Past research has noted that aspects of living in the United States place Latinos at risk for experiencing psychological problems. However, the specific features of the adaptation process that contribute to depression remain unclear. The purpose of the present study was to investigate the ability of acculturation, acculturative stress, and coping to predict membership into low, medium, and high groups of depression among Latinos. Within a group of 148 Latino adults from the community, a multinomial logistic regression revealed that an Anglo orientation, English competency pressures, and active coping differentiated high from low depression and that a Latino orientation and, to some extent, the pressure to acculturate distinguished medium from low depression. These results highlight a pattern of characteristics that function as risk and protective factors in relation to level of symptom severity. The findings are discussed in terms of implications for Latino mental health, including considerations for intervention and prevention. PsycINFO Database Record (c) 2010 APA, all rights reserved.

Full Text Available Background: Currently, depression among medical students is an important health issue at the global level. There is also a paucity of information on its relation to the stress level. Objective: The aim of this study is to assess the prevalence of depression and its relation to stress level and other factors among medical students. Materials and Methods: A cross-sectional study was conducted among medical students at a tertiary care medical institution in Puducherry, coastal south India. Beck Depression Inventory Scale was used for screening of depression and Cohen's Perceived Stress scale to assess perceived stress level. Data on associated factors were collected by self-administered questionnaire. Results: The overall prevalence of depression was found to be 48.4% (215/444. According to the cutoff scores, 229 (51.6% students scored as normal (0–9, 149 (33.6% as mild (10–18, 60 (13.5% as moderate (19–29, 3 (0.7% as severe (30–40, and 3 (0.7% students scored as very severe (>40 depression. Depression was significantly less among those with mild stress (adjusted odds ratio [OR] = 0.010 and moderate stress level (adjusted OR = 0.099 compared to severe stress level and those without interpersonal problems (adjusted OR = 0.448. Conclusion: Depression is more common among medical students. Stress coping mechanisms and improvement of interpersonal relationship may help to reduce depressive symptoms among medical students.

This study examined whether particular maternal and infant factors can identify mothers at risk for increased stress upon admission to the neonatal intensive care unit (NICU). Eighty-five mothers of preterm infants (25-34 weeks gestation) were assessed using the Parental Stressor Scale (PSS:NICU) and the Edinburgh Postnatal Depression Scale (EPDS) within 3.24 ± 1.58 d postpartum. Hierarchical linear regression models were used to determine the extent to which maternal stress is influenced by individual factors. Fifty-two percent of mothers experienced increased stress (PSS:NICU score ≥3) and 38% had significant depressive symptoms (EPDS score ≥10). Stress related to alterations in parental role was the most significant source of stress among NICU mothers. Distance from the hospital and married marital status were significant predictors for stress related to alterations in parental role (p = 0.003) and NICU sights and sounds (p = 0.01), respectively. Higher stress levels were associated with higher depressive scores (p = 0.001). Maternal mental health factors, demographic factors, pregnancy factors and infant characteristics were not associated with increased stress. Elevated stress levels and depressive symptoms are already present in mothers of preterm infants upon NICU admission. Being married or living long distance from the hospital is associated with higher stress. Future work is needed to develop effective interventions for alleviating stress in NICU mothers and preventing its potential development into postnatal depression.

Research has demonstrated that perceived stress and depression are risk factors for suicidal ideation in young adults, particularly women attending college. Female undergraduate students (N = 928) were administered measures assessing their levels of stress, depressive symptoms, suicidal thoughts, and mindfulness. A moderated-mediation analysis was conducted to examine the complex associations among these variables. Results indicated that mindfulness moderated the mediated effect of depressive symptoms on perceived stress and suicidal ideation. Specifically, the indirect effect was stronger in college women with lower levels of mindfulness as compared to those students who reported higher mindfulness. Thus, teaching mindfulness techniques on college campuses may be an important strategy for preventing suicide, especially among young adult women experiencing stress and depressive symptoms.

Psychiatrists in clinical practice face a number of stressors related to patient care, such as overwork. On the other hand, they gain satisfaction from their work. We quantified and assessed the potential relationship between levels of occupational stress, satisfaction, and depressive symptoms among Japanese clinical psychiatrists. We surveyed 206 psychiatrists with up to 15 years of clinical experience who primarily worked in patient care. Levels of occupational stress and occupational satisfaction were measured using the Visual Analogue Scale and the level of depressive symptoms was measured by the Center for Epidemiologic Studies Depression Scale. Workplace stressors and satisfiers were also evaluated. Out of 206 psychiatrists, 154 (74.8%) responded to the survey. The respondents' mean (SD) age was 34.3 (5.2) years. The estimated prevalence of significant depressive symptoms was 34.4% (n = 53), and the experienced frequent violence was 14.9% (n = 23). The level of depressive symptoms was inversely correlated with the level of occupational satisfaction. In respondents who reported a moderate level of occupational stress, having fewer depressive symptoms was associated with higher occupational satisfaction, but this association was not significant in those who reported a high level of stress. In addition, high occupational satisfaction was associated with interest towards work content, ability to work at one's discretion, opportunities for growth and career development, and ease of communication with supervisors and colleagues. Nearly one-third of the psychiatrists screened positive for significant depressive symptoms. Having fewer depressive symptoms was associated with higher occupational satisfaction in those who reported a moderate level of stress. Implications from the present findings may be to enhance occupational satisfaction by discussing work interests with a supervisor, as well as increased opportunities for career development, which may

To determine the prevalence of and factors associated with depression and stress with perceived quality of life and the salivary cortisol levels in Community Health Agent (CHA). Materials and Methods Cross-sectional descriptive study of CHAs in Pelotas-RS, Brazil. Data collection, including sociodemographic information and factors related to work and health. Beck Depression Inventory (BDI) II was used to assess depressive symptoms, Inventory of Stress Symptoms Lipp (ISSL) was used for the analysis of stress and the WHOQOL-BREF was used to investigate quality of life. Salivary cortisol was quantified via ELISA test. The assessments showed that 71.0% are in a state of stress resistance, 30.5% were in the alert state of stress and 32.8% were in the stress state of exhaustion. Depressive episodes (BDI≥12) were observed in 28.2%. The environmental domain had the lowest score for quality of life. We observed significantly higher salivary cortisol levels in CHAs with less than 1 year of service and with the lowest quality of life scores in the environmental subsection. A high prevalence of stress and depression was observed in this sample of CHAs. In addition, the worst levels of quality of life were identified in the environmental subsection. Cortisol levels corroborate these findings regarding quality of life within the environmental domain and began working less than a year previously.

Inadequate physical activity has adverse health consequences among adolescents. Mental health problem can be developed by lack of physical activity however it is controversial. The current study aimed to examine the association between level of physical activity with depression, anxiety and stress symptoms among adolescents. A representative sample of 1747 adolescents (13-14 years) was randomly selected from 6 schools in a south part of Malaysia. Respondents were asked to fill consent form, and questionnaires including Depression Anxiety and Stress Scale-21 and Physical Activity Questionnaire for Adolescents. Majority of respondents (71.9%) was Malay and more than half of the adolescents had low physical activity. About 40% had depression symptoms, followed by anxiety symptoms (65.9%) and stress symptoms (38.5%). Level of physical activity was significantly associated with gender, anxiety and stress (P<0.001). There were no associations with race, religion and depression symptom. This study provides some evidence among school-going adolescents related to anxiety and stress symptoms and low physical activities. Further studies are needed to show the protection effects of higher physical activity for depression, anxiety and stress symptoms in adolescents.

Postpartum depression affects a huge number of women and has detrimental consequences. Knowing the factors associated with postpartum depression during pregnancy can help its prevention. Although there is evidence surrounding behavioral or psychological predictors of postpartum depression, there is a lack of evidence of biological forecasters. The aim of this study was to analyze the sociodemographic, obstetric, and psychological variables along with hair cortisol levels during the first, second, and third trimesters of pregnancy that could predict postpartum depression symptoms. A sample of 44 pregnant women was assessed during 3 trimesters of pregnancy and the postpartum period using psychological questionnaires and hair cortisol levels. Participants were divided into 2 groups: a group with postpartum depression symptoms and a group with no postpartum depression symptoms. Results showed significant positive differences between groups in the first trimester regarding the Somatization subscale of the SCL-90-R (p Depression, Anxiety, and GSI subscales (p postpartum depression symptoms. In conclusion, our study provided evidence that psychopathological symptoms, pregnancy-specific stress, and hair cortisol levels can predict postpartum depression symptoms at different time-points during pregnancy. These findings can be applied in future studies and improve maternal care in clinical settings.

This study aimed to examine the relationship between work stress and depression; and investigate the mediating effect of occupational burnout among nurses in paediatric intensive care units. The relationships among work stress, occupational burnout and depression level have been explored, neither regarding occupational burnout as the mediating role that causes work stress to induce depression nor considering the paediatric intensive care unit context. A cross-sectional correlational design was conducted. One hundred and forty-four female paediatric intensive care unit nurses from seven teaching hospitals in southern Taiwan were recruited as the participants. Data were collected by structured questionnaires including individual demographics, the Nurse Stress Checklist, the Occupational Burnout Inventory and the Taiwan Depression Questionnaire. The results indicated that after controlling for individual demographic variables, the correlations of work stress with occupational burnout, as well as work stress and occupational burnout with depression level were all positive. Furthermore, occupational burnout may exert a partial mediating effect on the relationship between work stress and depression level. This study provides information about work stress, occupational burnout and depression level, and their correlations, as well as the mediating role of occupational burnout among paediatric intensive care unit nurses. It suggests government departments and hospital administrators when formulating interventions to prevent work stress and occupational burnout. These interventions can subsequently prevent episodes of depression in paediatric intensive care unit nurses, thereby providing patients with a safe and high-quality nursing environment. © 2016 John Wiley & Sons Ltd.
Full Text Available Background: Mental health disorders affect around 500 million people worldwide. In India, around 10-12% of people are affected by a mental disorder either due to stress, depression, anxiety, or any other cause. Mental health of workers affects the productivity of the workplace, with estimates putting these losses to be over 100 million dollars annually. Aims: The study aims to measure depression, anxiety, and stress levels of workers in an industry and to investigate if it has any effect on productivity of the firm. Materials and Methods: The study utilized a cross-sectional design and was conducted among workmen of the firm. A sociodemographic based questionnaire and a mental health screening tool -Depression Anxiety Stress Scale (DASS-21 were used for the same. A total of 90 completed questionnaires were analyzed for the study. The data was analyzed for central tendencies as well as for any associations and correlations. Results: The study showed that none of the workers had a positive score for depression. It also showed that around 36% of the workers had a positive score for anxiety and 18% of the workers had a positive score for stress on DASS-21 scale. The odds ratio between stress and number of leaves taken by a worker in the last 3 months suggested a dose-response relationship, but was statistically insignificant. Conclusion: The study found a prevalence rate of around 18-36% for anxiety and stress amongst the workers at the factory. Large-scale studies will help understand the effect mental health status has on the Indian workplace.

Full Text Available Abstract Background Given that the prevalence of antenatal and postnatal depression is high, with estimates around 13%, and the consequences serious, efforts have been made to identify risk factors to assist in prevention, identification and treatment. Most risk factors associated with postnatal depression have been well researched, whereas predictors of antenatal depression have been less researched. Risk factors associated with early parenting stress have not been widely researched, despite the strong link with depression. The aim of this study was to further elucidate which of some previously identified risk factors are most predictive of three outcome measures: antenatal depression, postnatal depression and parenting stress and to examine the relationship between them. Methods Primipara and multiparae women were recruited antenatally from two major hoitals as part of the beyondblue National Postnatal Depression Program 1. In this subsidiary study, 367 women completed an additional large battery of validated questionnaires to identify risk factors in the antenatal period at 26–32 weeks gestation.

The aim of this study was to investigate the correlation between levels of depression symptoms and age, thyroid-stimulating hormone levels, and stressful life events of the participants. Patients above 18 years old, with any thyroid disorders, and without psychiatric disorders were included in this study. All participants completed the Depression Anxiety Stress Scale 21 (DASS-21). The depression symptom score was calculated and interpreted as follows: less than 9: no depression; between 10 and 13: mild depression; between 14 and 20: moderate depression; between 21 and 27: severe depression, and more than 28: extremely severe depression. The total number of participants in this study was 199. There was no correlation between age, thyroid stimulating hormone, and the DASS score. There was also no significant difference in the DASS-21 score between genders. However, there was a positive correlation between depression symptoms and stressful life events (r=0.201, n=199, p < 0.05). These findings would suggest that increased depression symptom scores correlate with increased stressful life events. A larger study should be undertaken to confirm these findings.

A relationship between genetic makeup and susceptibility to major depressive disorder (MDD) has long been suspected on the basis of family and twin studies. A metaanalysis of reports on the basis of twin studies has estimated MDD's degree of heritability to be 0.33 (confidence interval, 0.26-0.39). Among families exhibiting an increased prevalence of MDD, risk of developing the illness was enhanced in members exposed to a highly stressful environment. Aberrant genes can predispose to depression in a number of ways, for example, by diminishing production of growth factors that act during brain development. An aberrant gene could also increase or decrease a neurotransmitter's release into synapses, its actions, or its duration of activity. The gene products of greatest interest at present are those involved in the synthesis and actions of serotonin; among them, the serotonin-uptake protein localized within the terminals and dendrites of serotonin-releasing neurons. It has been found that the Vmax of platelet serotonin uptake is low in some patients with MDD; also, Vmax is highly correlated in twins. Antidepressant drugs such as the selective serotonin reuptake inhibitors act on this uptake protein. The specific genetic locus causing serotonin uptake to be lower in some patients with major depression involves a polymorphic region (5-HTTLPR) in the promoter region of the gene for the uptake protein. The gene itself exists as several alleles, the short "S" allele and the long "L" allele. The S variant is associated with less, and the L variant with more, of the uptake protein. The effect of stressful life events on depressive symptoms in young adults was found to be significantly stronger among SS or SL subjects than among LL subjects. Neuroimaging studies showed that people with the SS or SL alleles exhibited a greater activation of the amygdala in response to fearful stimuli than those with LL. It has been reported recently that mutations in the gene that controls

Cardiovascular Reactivity in Patients With Major Depressive Disorder With High- or Low-Level Depressive Symptoms: A Cross-Sectional Comparison of Cardiovascular Reactivity to Laboratory-Induced Mental Stress.
Wang, Mei-Yeh; Chiu, Chen-Huan; Lee, Hsin-Chien; Su, Chien-Tien; Tsai, Pei-Shan
Depression increases the risk of adverse cardiac events. Cardiovascular reactivity is defined as the pattern of cardiovascular responses to mental stress. An altered pattern of cardiovascular reactivity is an indicator of subsequent cardiovascular disease. Because depression and adverse cardiac events may have a dose-dependent association, this study examined the differences in cardiovascular reactivity to mental stress between patients with major depressive disorder (MDD) with high depression levels and those with low depression levels. Moreover, autonomic nervous system regulation is a highly plausible biological mechanism for the pattern of cardiovascular reactivity to mental stress. The association between cardiovascular reactivity and parameters of heart rate variability (HRV), an index for quantifying autonomic nervous system activity modulation, was thus examined. This study included 88 patients with MDD. HRV was measured before stress induction. The Stroop Color and Word Test and mirror star-tracing task were used to induce mental stress. We observed no significant association between depressive symptom level and any of the cardiovascular reactivity parameters. Cardiovascular reactivity to mental stress was comparable between patients with MDD with high-level depressive symptoms and those with low-level depressive symptoms. After adjusting for confounding variables, the high-frequency domain of HRV was found to be an independent predictor of the magnitude of heart rate reactivity (β = -.33, p = .002). In conclusion, the magnitude of cardiovascular reactivity may be independent of depression severity in patients with MDD. The autonomic regulation of cardiovascular responses to mental stress primarily influences heart rate reactivity in patients with MDD. © The Author(s) 2015.

Adolescence is a transition period from childhood to early adulthood. Because of the immense pressure imposed on adolescents due to the complications and ambiguities of this transition, their level of excitement increases and sometimes it appears in the form of sensitivity and intense excitement. This study aimed at determining the effectiveness of assertiveness training on the levels of stress, anxiety, and depression of high school students. This quasi-experimental study was conducted on high school students of Isfahan in academic year 2012 - 13. A total of 126 second grade high school students were collected according to simple random sampling method and divided into two groups: experimental with 63 participants and control with the same number. Data gathering instruments included a demographic questionnaire, Gambill-Richey assertiveness scale, and depression anxiety stress scales (DASS-21). Assertiveness training was carried out on the experimental group in 8 sessions; after 8 weeks, posttest was carried out on both groups. Statistical tests such as independent t test, repeated measures ANOVA, Chi-square test, and the Mann-Whitney test were used to interpret and analyze the data. The Chi-square and Mann-Whitney tests did not show significant statistical differences between the two groups in terms of demographic variables (P ≥ 0.05). Repeated measures ANOVA showed no significant difference between the mean scores for assertiveness before (100.23 ± 7.37), immediately after (101.57 ± 16.06), and 2 months after (100.77 ± 12.50) the intervention in the control group. However, the same test found a significant difference between the mean score for assertiveness in the experimental group before (101.6 ± 9.1), immediately after (96.47 ± 10.84), and 2 months after (95.41 ± 8.37) implementing the training program (P = 0.002). The independent t test showed no significant difference in the mean score for anxiety and stress between two groups before the
Full Text Available Background: Nurses face a great amount of stress that can threaten their health and reduce their motivation. Nurses′ present working conditions lead to an increase in emotional pressures and depression. Conducting a study on this seems to be necessary, with regard to nurses′ stressful working conditions, in order to take steps toward achieving different and non-meditational treatments to treat their stress, anxiety, and depression and, consequently, promote nurses′ and patients′ health. Materials and Methods: This is a randomized clinical trial conducted on 52 nurses working in cancer patients wards, who were randomly assigned to intervention and control groups. Happiness educational program was administered for six sessions once a week in the study group and a communication training sessions with the patients in the control group, and DASS-42 questionnaire was completed before, immediately after, and 1 month after intervention by the subjects in both study and control groups. Data were analyzed by Chi-square, independent t-test, and analysis of variance (ANOVA through SPSS 18. Results: Mean scores of stress, anxiety, and depression showed no significant difference before and after intervention. Meanwhile, independent t-test showed that mean scores of stress, anxiety, and depression were significantly lower in the study group compared to the control group immediately after and 1 month after intervention (P < 0.05. Conclusions: Educational planning of happiness can reduce nurses′ depression, anxiety, and stress in the cancer patients′ wards. Psychiatric nurses can reduce depression, anxiety, and stress of nurses working in other hospitals also through application of this program.

The aim of this study is to determine the effects of continuous positive airway pressure (CPAP) treatment on depression, anxiety, and perceived stress levels and to identify factors predictive of treatment efficacy in patients with obstructive sleep apnea syndrome (OSAS). This study included 51 patients admitted to the Adiyaman University Medical School Otorhinolaryngology Department or Eskisehir Yunus Emre State Hospital between January and September 2014 with one or more complaints including snoring, excessive daytime sleepiness, or apnea witnessed by the partner. Diagnosis of OSAS was made by polysomnography and CPAP treatment was initiated. Depression levels were assessed in all study subjects using the Hospital Anxiety and Depression Scale (HADS) at the start of treatment and at 3 months. Anxiety levels were assessed using both the HADS and the State and Trait Anxiety Inventory (STAI), and perceived stress level was assessed using the Perceived Stress Questionnaire (PSQ). After CPAP treatment, we observed significant decreases in both the Depression and Anxiety Subscales of the HADS, in the Trait Anxiety subscale of the STAI, and in the PSQ. An evaluation of the initial parameters that predict improvements in these scales revealed that snoring time predicted decreases in all scale scores. In OSAS patients CPAP treatment has positive effects on psychological parameters like depression, anxiety, and perceived stress. We suggest that possible psychogenic benefits should be considered when deciding to start CPAP treatment, particularly in patients with pronounced and extended snoring who may also have social problems.

The purpose of this study was to compare anxiety, depression, and stress between mothers of children during maintenance treatment for acute lymphoblastic leukemia (ALL) and matched controls. Twenty-six mothers were recruited from the hematology unit at a children's hospital, and 26 mothers were recruited from the community. Participants were matched to their child's age and gender. Mothers completed the Hospital Anxiety and Depression Scale, the Perceived Stress Sale, and collected salivary cortisol 4 times a day for 3 consecutive days. Compared with mothers of healthy children, anxiety scores did not differ (P=.10), but depression scores were higher (P=.003) in mothers of children with ALL. More mothers in the ALL group scored above the cutoff of 7 indicating clinical anxiety (46%) and depressive symptoms (27%). A trend toward increased stress was found in mothers in the ALL group. No difference was found in overall daily cortisol (area under the curve), daily decrease in cortisol (slope), and cortisol awakening response. Mothers of children with ALL experienced emotional symptoms many months after the initial diagnosis.

Full Text Available Kai-xin-san (KXS, a Chinese herbal decoction being prescribed by Sun Simiao in Beiji Qianjin Yaofang about 1400 years ago, contains Ginseng Radix et Rhizoma, Polygalae Radix, Acori tatarinowii Rhizoma, and Poria. KXS has been used to treat stress-related psychiatric disease with the symptoms of depression and forgetfulness in ancient China until today. However, the mechanism of its antidepression action is still unknown. Here, the chronic mild-stress-(CMS- induced depressive rats were applied in exploring the action mechanisms of KXS treatment. Daily intragastric administration of KXS for four weeks significantly alleviated the CMS-induced depressive symptoms displayed by enhanced sucrose consumption. In addition, the expressions of those molecular bio-markers relating to depression in rat brains were altered by the treatment of KXS. These KXS-regulated brain biomarkers included: (i the levels of dopamine, norepinephrine, and serotonin (ii the transcript levels of proteins relating to neurotransmitter metabolism; (iii the transcript levels of neurotrophic factors and their receptors. The results suggested that the anti-depressant-like action of KXS might be mediated by an increase of neurotransmitters and expression of neurotrophic factors and its corresponding receptors in the brain.

Kai-xin-san (KXS), a Chinese herbal decoction being prescribed by Sun Simiao in Beiji Qianjin Yaofang about 1400 years ago, contains Ginseng Radix et Rhizoma, Polygalae Radix, Acori tatarinowii Rhizoma, and Poria. KXS has been used to treat stress-related psychiatric disease with the symptoms of depression and forgetfulness in ancient China until today. However, the mechanism of its antidepression action is still unknown. Here, the chronic mild-stress-(CMS-) induced depressive rats were applied in exploring the action mechanisms of KXS treatment. Daily intragastric administration of KXS for four weeks significantly alleviated the CMS-induced depressive symptoms displayed by enhanced sucrose consumption. In addition, the expressions of those molecular bio-markers relating to depression in rat brains were altered by the treatment of KXS. These KXS-regulated brain biomarkers included: (i) the levels of dopamine, norepinephrine, and serotonin (ii) the transcript levels of proteins relating to neurotransmitter metabolism; (iii) the transcript levels of neurotrophic factors and their receptors. The results suggested that the anti-depressant-like action of KXS might be mediated by an increase of neurotransmitters and expression of neurotrophic factors and its corresponding receptors in the brain. Thus, KXS could serve as alternative medicine, or health food supplement, for patients suffering from depression. PMID:22973399
Full Text Available Adolescent pregnant women are at greater risk for nutritional deficits, stress, and depression than their adult counterparts, and these risk factors for adverse pregnancy outcomes are likely interrelated. This study evaluated the prevalence of nutritional deficits in pregnant teenagers and assessed the associations among micronutrient dietary intake, stress, and depression. One hundred and eight pregnant Latina adolescents completed an Automated Self-Administered 24-hour dietary recall (ASA24 in the 2nd trimester. Stress was measured using the Perceived Stress Scale and the Prenatal Distress Questionnaire. Depressive symptoms were evaluated with the Reynolds Adolescent Depression Scale. Social support satisfaction was measured using the Social Support Questionnaire. More than 50% of pregnant teenagers had an inadequate intake (excluding dietary supplement of folate, vitamin A, vitamin E, iron, zinc, calcium, magnesium, and phosphorous. Additionally, >20% of participants had an inadequate intake of thiamin, riboflavin, niacin, vitamin B6, vitamin B12, vitamin C, copper, and selenium. Prenatal supplement inclusion improved dietary intake for most micronutrients except for calcium, magnesium, and phosphorous, (>50% below the Estimated Average Requirement (EAR and for copper and selenium (>20% below the EAR. Higher depressive symptoms were associated with higher energy, carbohydrates, and fats, and lower magnesium intake. Higher social support satisfaction was positively associated with dietary intake of thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, vitamin C, vitamin E, iron, and zinc. The findings suggest that mood and dietary factors are associated and should be considered together for health interventions during adolescent pregnancy for the young woman and her future child.

Full Text Available Depression, though generally episodic, results in lasting disability, distress, and burden. Rising prevalence of depression and suicide in the context of epidemiological transition demands more attention to social dimensions like gender related stresses, dysfunction, and their role in outcome of depression. Cross-sectional and follow-up assessment of men and women with depression at a psychiatric tertiary centre was undertaken to compare their illness characteristics including suicidal ideation, stresses, and functioning on GAF, SOFAS, and GARF scales (N=107. We reassessed the patients on HDRS-17 after 6 weeks of treatment. Paired t-test and chi-square test of significance were used to compare the two groups, both before and after treatment. Interpersonal and marital stresses were reported more commonly by women (P<0.001 and financial stresses by men (P<0.001 though relational functioning was equally impaired in both. Women had suffered stresses for significantly longer duration (P=0.0038. Men had more impairment in social and occupational functioning compared to females (P=0.0062. History of suicide attempts was significantly associated with more severe depression and lower levels of functioning in case of females with untreated depression. Significant cross-gender differences in stresses, their duration, and types of dysfunction mandate focusing on these aspects over and above the criterion-based diagnosis.

To measure the occurrence and levels of depression, anxiety and stress in undergraduate dental students using the Depression, Anxiety and Stress Scale (DASS-21). This cross-sectional study was conducted in November and December of 2014. A total of 289 dental students were invited to participate, and 277 responded, resulting in a response rate of 96%. The final sample included 247 participants. Eligible participants were surveyed via a self-reported questionnaire that included the validated DASS-21 scale as the assessment tool and questions about demographic characteristics and methods for managing stress. Abnormal levels of depression, anxiety and stress were identified in 55.9%, 66.8% and 54.7% of the study participants, respectively. A multiple linear regression analysis revealed multiple predictors: gender (for anxiety b=-3.589, p=.016 and stress b=-4.099, p=.008), satisfaction with faculty relationships (for depression b=-2.318, p=.007; anxiety b=-2.213, p=.004; and stress b=-2.854, prelationships (for depression b=-3.527, panxiety b=-2.213, p=.004; and stress b=-2.854, pstress b=-2.648, p=.045). The standardized coefficients demonstrated the relationship and strength of the predictors for each subscale. To cope with stress, students engaged in various activities such as reading, watching television and seeking emotional support from others. The high occurrence of depression, anxiety and stress among dental students highlights the importance of providing support programs and implementing preventive measures to help students, particularly those who are most susceptible to higher levels of these psychological conditions.
Full Text Available Background and Objectives Exercises bring about health. Therefore, knowing what kind of exercise is more effective in individuals’ spirituals health indices is important. Thus, the present study aims at comparing the impact of aerobic and anaerobic exercises on the level of depression, anxiety, stress, and happiness of nonathletic male students. Methods In this clinical trial study, sample included the nonathletic male students of Zahedan Azad University in 2014. 90 students were selected through convenience sampling and they were divided randomly into two experimental groups (aerobic and anaerobic and one control group. The aerobic group must do aerobic exercises and the anaerobic group must do anaerobic exercises for a period of 10 weeks (3 sessions a week, each lasted for 60 minutes. The data were collected using DASS-21 questionnaire for measuring the level of depression, anxiety and stress, and Oxford OHI questionnaire for measuring the amount of happiness before and after the intervention. The results were analyzed using statistical tests of MANCOVA in SPSS-13. Results The results showed that in both aerobic and anaerobic groups the mean score of depression, anxiety, stress and happiness improved after treatment. However, the improve in the mean score of anxiety, stress and happiness was more apparent in the anaerobic group. The results also showed that only stress and happiness resulted in a significant difference in different groups. Conclusions Both aerobic and anaerobic exercises result in reduction of stress and Anxiety. So it seems necessary to include such exercises in students’ daily schedule.

An experimental design was used to test whether self-reported, psychophysiological and symptomatic stress-responses increase as a function of the underlying vulnerability to psychosis as proposed by vulnerability-stress-models. Stress-responses of participants with psychotic disorders (PSY, n = 35) were compared to those of participants with attenuated positive symptoms (AS, n = 29), first-degree relatives of persons with psychotic disorders (REL, n = 26), healthy controls (HC, n = 28) and controls with depression (DEP, n = 30). Using a repeated measures design, participants were assigned to a noise stressor, a social stressor and a no stress condition in random order. Stress-responses were assessed via self-report, salivary cortisol levels, heart rate and skin conductance levels. State-paranoia and depression were assessed with clinical scales. PSY reported to be significantly more stressed than HC, AS and REL across all conditions which went along with increased heart rate and decreased overall cortisol release. In contrast, AS showed elevated levels of cortisol. PSY showed a stronger response of self-reported stress to the noise condition compared to the no stress condition than HC, but no stronger response than the other samples. Furthermore, the stressors did not trigger stronger psychophysiological responses or symptom-increases in PSY. The social stressor was brief and not individualized and did not have an effect on cortisol. The findings support the notion that subjective stress-responsiveness increases with vulnerability, but not the assumption that symptoms arise directly as a function of stress and vulnerability. Also, the generally high levels of arousal seem to be more relevant to psychosis than the responsiveness to specific stressors. Copyright © 2014 Elsevier Ltd. All rights reserved.

The goal of this study was to examine chronic and episodic stress in children of mothers with and without a history of major depressive disorder (MDD) during the children's lives. Participants were 255 mothers selected according to their history of MDD (present vs. absent during child's life) and their children (age 8-14; 53% girls, 81% Caucasian). Mothers' and children's histories of MDD were assessed using diagnostic interviews, and their depressive symptoms were assessed via self-report measures. Children's levels of chronic and episodic stress were assessed using a semistructured contextual threat interview. Children of mothers with a history of recurrent MDD, compared to single MDD or no depression, experienced more chronic stress within several domains including peers, mother-child relations, and other family member relations as well as greater episodic dependent interpersonal stress. Each of these group differences was maintained after excluding children with a history of MDD themselves and controlling for their current depressive symptoms. However, only the group difference in chronic peer stress was maintained when controlling for mothers' current depression. The results suggest that children exposed to recurrent maternal MDD experience higher levels of both chronic and episodic stress, at least some of which they contribute to themselves (dependent interpersonal stress) and which is at least partially independent of the effects of children's depression. In addition, much of this stress is associated primarily with current depression in the mother, though it appears that chronic peer stress may remain elevated even after the remission of maternal depression.
Full Text Available Adolescence is a time of continued brain maturation, particularly in limbic and cortical regions, which undoubtedly plays a role in the physiological and emotional changes. Juvenile rats repeatedly exposed to prenatal stress (PS exhibit behavioral features often observed in neuropsychiatric disorders including depression. However, to date the underlying neurological mechanisms are still unclear. In the current study, juvenile offspring rats whose mothers were exposed to PS were evaluated for depression-related behaviors in open field and sucrose preference test. NMDA receptor subunits NR1 and NR2A in the hippocampus, frontal cortex and striatum were assayed by western blotting. The results indicated that PS resulted in several behavioral anomalies in the OFT and sucrose preference test. Moreover, reduced levels of NMDA receptor subunits NR1 and NR2A in the hippocampus, and NR1 in prefrontal cortex and striatum of prenatally stressed juvenile offspring were found. Treatment with MK-801 to pregnant dams could prevent all those changes in the juvenile offspring. Collectivity, these data support the argument that PS to pregnant dams could induce depression-like behavior, which may be involved with abnormal expression of NR1 and NR2A in specific brain regions, and MK-801 may have antidepressant-like effects on the juvenile offspring.

MicroRNAs (miRNAs) are involved in stress-related pathologies. However, the molecular mechanisms underlying stress resilience are elusive. Using chronic mild stress (CMS), an animal model of depression, we identified animals exhibiting a resilient phenotype. We investigated serum levels of corticosterone, melatonin and 376 mature miRNAs to find peripheral biomarkers associated with the resilient phenotype. miR-16, selected during screening step, was assayed in different brain regions in order to find potential relationship between brain and peripheral alterations in response to stress. Two CMS experiments that lasted for 2 and 7 consecutive weeks were performed. During both CMS procedures, sucrose consumption levels were significantly decreased in anhedonic-like animals (panimals, whereas the drinking profiles of resilient rats did not change despite the rats being stressed. Serum corticosterone measurements indicated that anhedonic-like animals had blunted hypothalamic-pituitary-adrenal (HPA) axis activity, whereas resilient animals exhibited dynamic responses to stress. miRNA profiling revealed that resilient animals had elevated serum levels of miR-16 after 7 weeks of CMS (adjusted p-valueanimals exhibited reciprocal changes in miR-16 expression level in mesocortical pathway after 2 weeks of CMS (panimals can actively cope with stress on a biochemical level and miR-16 may contribute to a "stress-resistant" behavioral phenotype by pleiotropic modulation of the expression of genes involved in the function of the nervous system.

Horticultural therapy (HT) is a subgroup of occupational therapy (OT). Both HT and OT have been successful as adjunctive treatment modalities in substance abuse treatment. Studies have indicated that gardening promotes neuroendocrine and affective restoration from stress. The study intended to assess the effect of HT versus nonhorticultural OT on cortisol levels, depression, symptoms of posttraumatic stress disorder (PTSD), alcohol cravings, and quality of life. The research team designed a randomized pilot study. The study was open for participation from July 2012-October 2012. It took place during multiple occurrences of a 28-d treatment programs for substance use disorder at a Veterans Affairs medical center. Participants • Participants were 49 veterans, averaging 46.4 y old (SD = 11.9); the dropout rate was 37%. Participants were randomly assigned to the HT or the OT group. They attended supervised HT and OT groups 5 h/d for 3 wk. Outcome Measures • Pre- and posttreatment, participants completed the Quality of Life Enjoyment and Satisfaction Questionnaire-Short Form (Q-LES-Q-SF), the Alcohol Craving Questionnaire (ACQ-NOW), the Posttraumatic Stress Disorder Checklist Civilian Version (PCLC), and the Center for Epidemiologic Studies Depression Scale (CES-D). Salivary cortisol samples were taken at wk 1, 2, and 3. A repeated measures analysis of variance (ANOVA) (F2,20 = 0.878) revealed that the HT performed was associated with a 12% reduction in salivary cortisol levels from wk 1 to wk 3, but the difference was not statistically significant (P = .43). Separate 1-way analyses of covariance (ANCOVAs) revealed no statistically significant differences in the self-administered tests, although both the Q-LES-Q-SF and CES-D showed a trend toward improving quality of life and depressive symptoms in the HT group compared with the OT group. Additional analysis of the nonbiologic tests suggests that most participants in the HT and OT had some benefit from the

Emodin, the major active component of Rhubarb, has shown neuroprotective activity. This study is attempted to investigate whether emodin possesses beneficial effects on chronic unpredictable mild stress (CUMS)-induced behavioral deficits (depression-like behaviors) and explore the possible mechanisms. ICR mice were subjected to chronic unpredictable mild stress for 42 consecutive days. Then, emodin and fluoxetine (positive control drug) were administered for 21 consecutive days at the last three weeks of CUMS procedure. The classical behavioral tests: open field test (OFT), sucrose preference test (SPT), tail suspension test (TST) and forced swimming test (FST) were applied to evaluate the antidepressant effects of emodin. Then plasma corticosterone concentration, hippocampal glucocorticoid receptor (GR) and brain-derived neurotrophic factor (BDNF) levels were tested to probe the mechanisms. Our results indicated that 6 weeks of CUMS exposure induced significant depression-like behavior, with high, plasma corticosterone concentration and low hippocampal GR and BDNF expression levels. Whereas, chronic emodin (20, 40 and 80 mg/kg) treatments reversed the behavioral deficiency induced by CUMS exposure. Treatment with emodin normalized the change of plasma corticosterone level, which demonstrated that emodin could partially restore CUMS-induced HPA axis impairments. Besides, hippocampal GR (mRNA and protein) and BDNF (mRNA) expressions were also up-regulated after emodin treatments. In conclusion, emodin remarkably improved depression-like behavior in CUMS mice and its antidepressant activity is mediated, at least in part, by the up-regulating GR and BDNF levels in hippocampus.

Posttraumatic stress disorder and major depressive disorder are well-established risk factors for suicidal behavior. This study compared depressed suicide attempters with and without comorbid posttraumatic stress disorder with respect to additional diagnoses, global functioning, depressive symptoms, substance abuse, history of traumatic exposure, and suicidal behavior. Adult patients consecutively admitted to a general hospital after a suicide attempt were interviewed and assessed for DSM-IV diagnosis and clinical correlates. Sixty-four patients (71%) were diagnosed with depression; of them, 21 patients (32%) had posttraumatic stress disorder. There were no group differences in social adjustment, depressive symptoms, or suicidal intent. However, the group with comorbid depression and posttraumatic stress disorder had more additional Axis I diagnoses, a higher degree of childhood trauma exposure, and more often reported previous suicide attempts, non-suicidal self-harm, and vengeful suicidal motives. These findings underline the clinical importance of diagnosis and treatment of posttraumatic stress disorder in suicide attempters.

The hippocampus is sensitive to stress which activates norepinephrine terminals deriving from the locus coeruleus. Melatonin exerts positive effects on the hippocampal neurogenic process and on depressive-like behaviour. Thus, in the present study, an examination was made of the effect of chronic melatonin treatment on norepinephrine content, synthesis, uptake, vesicular transport and degradation in the hippocampus of rats exposed to CUMS. This entailed quantifying the norephinephrine, mRNA and protein levels of DBH, NET, VMAT 2, MAO-A and COMT. The results show that CUMS evoked prolonged immobility. Melatonin treatment decreased immobility in comparison with the placebo group, reflecting an antidepressant-like effect. Compared with the placebo group, a dramatic decrease in norepinephrine content, decreased VMAT2 mRNA and protein and increased MAO-A protein levels in the hippocampus of the CUMS rats were observed. However, no significant differences in the levels of DBH, NET, COMT mRNA and protein and MAO-A mRNA levels between the placebo and the stressed groups were found. The results showed the restorative effects of melatonin on the stress-induced decline in the norepinephrine content of the hippocampus. It was observed that melatonin treatment in the CUMS rats prevented the stress-induced decrease in VMAT2 mRNA and protein levels, whereas it reduced the increase of the mRNA of COMT and protein levels of MAO-A. Chronic treatment with melatonin failed to alter the gene expression of DBH or NET in the hippocampus of the CUMS rats. Additionally, the results show that melatonin enhances VMAT2 expression and norepinephrine storage, whilst it reduces norepinephrine degrading enzymes. Copyright © 2016 Elsevier B.V. and ECNP.

The aim of this systematic review was to assess the effect of interventions to reduce stress in pregnant women with a history of miscarriage. A systematic review of randomised controlled trials (RCTs). A total of 13 medical, psychological and social electronic databases were searched from January 1995 to April 2016 including PUBMED, CENTRAL, Web of Science and EMBASE. This review focused on women in their subsequent pregnancy following miscarriage. All published RCTs which assessed the effect of non-medical interventions such as counselling or support interventions on psychological and mental health outcomes such as stress, anxiety or depression when compared with a control group were included. Stress, anxiety or depression had to be measured at least preintervention and postintervention. This systematic review found no RCT which met our initial inclusion criteria. Of the 4140 titles screened, 17 RCTs were identified. All of them were excluded. One RCT, which implemented a caring-based intervention, included pregnant women in their subsequent pregnancy; however, miscarriage was analysed as a composite variable among other pregnancy losses such as stillbirth and neonatal death. Levels of perceived stress were measured by four RCTs. Different types of non-medical interventions, time of follow-up and small sample sizes were found. Cohort studies and RCTs in non-pregnant women suggest that support and psychological interventions may improve pregnant women's psychological well-being after miscarriage. This improvement may reduce adverse pregnancy-related outcomes in subsequent pregnancies. However, this review found no RCTs which met our criteria. There is a need for targeted RCTs that can provide reliable and conclusive results to determine effective interventions for this vulnerable group. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Full Text Available Stress contributes to a variety of diseases and disorders such as depression and peptic ulcer. The present study aimed to investigate the correlation between stress ulcer and depression in pathogenesis and treatment by using chronic stress depression (CSD, chronic psychological stress ulcer (CPSU and water immersion restrain stress models in rats. Our data showed that the ulcer index of the animals after CSD exposure was significantly higher than that of controls. Depression-like behaviors were observed in rat after CPSU exposure. Fluoxetine hydrochloride significantly reduced the ulcer index of rats exposed to CPSU stress, while ranitidine inhibited depression-like behavior of the animals in CSD group. The ulcer index of rats administered with mifepristone after CPSU stress was markedly reduced compared to CPSU group, although there was no significant difference in the depression-like behavior between mifepristone-treated CSD group and naive controls. We also found that the rats exposed to CPSU or CSD stress displayed a lower level of corticosterone than naive controls, however, the acute stress (AS group showed an opposite result. Additionally, in order to study the relevance of H(2 receptors and depression, we treated the CSD group with cimetidine and famotidine respectively. The data showed that cimetidine inhibited depression-like behavior in CSD rats, and famotidine had no impact on depression. Overall our data suggested that the hypothalamic-pituitary-adrenal (HPA axis dysfunction may be the key role in triggering depression and stress ulcer. Acid-suppressing drugs and antidepressants could be used for treatment of depression and stress ulcer respectively. The occurrence of depression might be inhibited by blocking the central H(2 receptors.
Full Text Available As important as it is to fully comprehend the relationship between stress and depression among university students, it is also vital to ascertain the role of perceived social support as an essential psychosocial factor for effectively delimiting the deleterious impact of stress exposure. As such, the current study aimed to examine whether perceived social support functioned as a mediating factor in the relationship between stress and depression among university students. Data was collected from undergraduate students of a public university in Sarawak, Malaysia. Information on demographics, depression, stress and perceived social support were collated through self-report questionnaires. Results revealed significant gender differences for perceived social support, wherein female students reported lower levels of social support compared to their counterparts. Mediation analysis portrayed that the association between stress and depression was partially accounted for, by the mediating role of perceived social support.

We aimed to assess the association between depression, anxiety, stress and impulsivity with respect to age. The Depression, Anxiety and Stress Scale (DASS-42) and the Barratt Impulsiveness Scale (BIS-11) were administered to 145 individuals. Due to a negative correlation between age, BIS-11 and DASS-42 subscales, participants were divided into three groups: young-aged (18-30years), middle-aged (31-49years) and old-aged (≥50years). Subjects from old-aged group had significantly lower scores of depression, anxiety, stress and impulsivity compared to those from younger groups. Anxiety, followed by stress and depression, was the strongest predictor of BIS-11 total score in young-aged and middle-aged individuals. There were no significant differences in the correlations between BIS-11 total score, depression, anxiety and stress in old-aged individuals. Our results indicate that the levels of depression, anxiety, stress and impulsivity decrease with age. Additionally, age might moderate the effect of depression, anxiety and stress on impulsivity.

Mucopolysaccharidosis type III (MPS III, Sanfilippo syndrome) is a lysosomal storage disorder, caused by a deficiency in one of four enzymes involved in the catabolism of the glycosaminoglycan heparan sulphate. It is a degenerative disorder, with a progressive decline in children's intellectual and physical functioning. There is currently no cure for the disorder. To date there is a paucity of research on how this disorder impacts parents psychological functioning. Specifically, research in the area has failed to employ adequate control groups to assess if the impact of this disorder on parents psychological functioning differs from parenting a child with intellectual disability (ID). The current study examined child behaviour and parental psychological functioning in 23 parents of children with MPS III and 23 parents of children with ID. Parents completed postal questionnaires about their child's behaviour and abilities and their own psychological functioning. Parents of children with MPS III reported fewer behavioural difficulties as their child aged, more severe level of intellectual disability, and similar levels of perceived social support, coping techniques, stress, anxiety and depression levels as parents of children with ID. Both groups of parents scored above the clinical cut off for anxiety and depression. Parents of children with MPS III rated themselves as significantly less future-orientated and goal directed than parents of children with ID. Services should develop support packages for parents of children with MPS III that incorporate an understanding of the unique stressors and current-difficulty approach of this population. Future research should examine gender differences between parental psychological functioning, using mixed qualitative and quantitative approaches, and utilise matched developmental level and typically developing control groups.

Although exposure to early adversity and prior experiences with depression have both been associated with lower levels of precipitating life stress in depression, it is unclear whether these stress sensitization effects are similar for all types of stress or whether they are specific to stressors that may be particularly depressogenic, such as those involving interpersonal loss. To investigate this issue, we administered structured, interview-based measures of early adversity, depression history, and recent life stress to one hundred adults who were diagnosed with major depressive disorder. As predicted, individuals who experienced early parental loss or prolonged separation (i.e., lasting one year or longer) and persons with more lifetime episodes of depression became depressed following lower levels of life stress occurring in the etiologically-central time period of three months prior to onset of depression. Importantly, however, additional analyses revealed that these effects were unique to stressors involving interpersonal loss. These data highlight potential stressor-specific effects in stress sensitization and demonstrate for the first time that individuals exposed to early parental loss or separation, and persons with greater histories of MDD, may be selectively sensitized to stressors involving interpersonal loss.

Perinatal distress has largely been conceptualised as the experience of depression and/or anxiety. Recent research has shown that the affective state of stress is also present during the perinatal period and thus may add to a broader understanding of perinatal distress. The aims of the present study were to investigate the changes in depression, anxiety and stress symptoms across pregnancy, and to explore the prospective relationships between these symptoms. Two-hundred and fourteen pregnant women were recruited when they were less than 16 weeks gestation. Women completed depression, anxiety and stress measures on a monthly basis, from 16 weeks gestation through to 36 weeks gestation. The covariate measures of sleep quality and social support were assessed bi-monthly at 16, 24 and 32 weeks gestation. Levels of depression, anxiety and stress symptoms were all shown to change over time, with women experiencing fewer symptoms during the middle of their pregnancy. Higher symptoms early in pregnancy predicted higher symptom levels throughout the rest of pregnancy. Higher depression scores early in pregnancy were also shown to predict higher anxiety and higher stress scores in late pregnancy. Increased stress scores during mid pregnancy also predicted higher anxiety scores in late pregnancy. Current findings indicate that symptom levels of depression, anxiety and stress vary over the course of pregnancy. Increased depression in early pregnancy seemed to be particularly pertinent as it not only predicted later depression symptoms, but also increased anxiety and stress in late pregnancy. Collectively, these results further highlight the importance of emotional health screening early in pregnancy. Copyright © 2014 Australian College of Midwives. Published by Elsevier Ltd.

Prenatal stress (PNS) during critical periods of brain development has been associated with numerous behavioral and/or mood disorders in later life. These outcomes may result from changes in the hypothalamic-pituitary-adrenal (HPA) axis activity, which, in turn, can be modulated by environmental factors, such as nutritional status. In this study, the adult male offspring of dams exposed to restraint stress during the last semester of pregnancy and fed different diets were evaluated for depressive-like behavior in the forced swimming test and for the corticosterone response to the test. Female Wistar rats were allocated to one of three groups: regular diet, diet supplemented with coconut fat or with fish oil, offered during pregnancy and lactation. When pregnancy was confirmed, they were distributed into control or stress groups. Stress consisted of restraint and bright light for 45 min, three times per day, in the last week of pregnancy. The body weight of the adult offspring submitted to PNS was lower than that of controls. In the forced swimming test, time of immobility was reduced and swimming was increased in PNS rats fed fish oil and plasma corticosterone levels immediately after the forced swimming test were lower in PNS rats fed regular diet than their control counterparts; this response was reduced in control rats whose mothers were fed fish oil and coconut fat. The present results indicate that coconut fat and fish oil influenced behavioral and hormonal responses to the forced swimming test in both control and PNS adult male rats.

To describe the prevalence of symptoms of depression and anxiety, and the level of life stress and worry in late pregnancy for Māori and non-Māori women. In late pregnancy, women completed a questionnaire recording their prior history of mood disorders; self-reported current depressive symptoms (⩾13 on the Edinburgh Postnatal Depression Scale), current anxiety symptoms (⩾6 on the anxiety items from the Edinburgh Postnatal Depression Scale), significant life stress (⩾2 items on life stress scale) and dysfunctional worry (>12 on the Brief Measure of Worry Scale). Data were obtained from 406 Māori women (mean age = 27.6 years, standard deviation=6.3 years) and 738 non-Māori women (mean age = 31.6 years, standard deviation=5.3 years). Depressive symptoms (22% vs 15%), anxiety symptoms (25% vs 20%), significant life stress (55% vs 30%) and a period of poor mood during the current pregnancy (18% vs 14%) were more prevalent for Māori than non-Maori women. Less than 50% of women who had experienced ⩾2 weeks of poor mood during the current pregnancy had sought help. Being young was an independent risk factor for depressive symptoms, significant life stress and dysfunctional worry. A prior history of depression was also consistently associated with a greater risk of negative affect in pregnancy. Antenatal mental health requires at least as much attention and resourcing as mental health in the postpartum period. Services need to specifically target Māori women, young women and women with a prior history of depression.

The stress generation hypothesis was tested in two different longitudinal studies examining relations between weekly depression symptom ratings and stress levels in adolescents and emerging adults at varied risk for depression. Participants in Study 1 included 240 adolescents who differed with regard to their mother’s history of depressive disorders. Youth were assessed annually across 6 years (Grades 6 through 12). Consistent with the depression autonomy model, higher numbers of prior major depressive episodes (MDEs) were associated with weaker stress generation effects, such that higher levels of depressive symptoms predicted increases in levels of dependent stressors for adolescents with ≤ 2 prior MDEs, but depressive symptoms were not significantly related to dependent stress levels for youth with ≥ 3 prior MDEs. In Study 2, participants were 32 remitted-depressed and 36 never-depressed young adults who completed a psychosocial stress task to determine cortisol reactivity and were re-assessed for depression and stress approximately eight months later. Stress generation effects were moderated by cortisol responses to a laboratory psychosocial stressor, such that individuals with higher cortisol responses exhibited a pattern consistent with the depression autonomy model, whereas individuals with lower cortisol responses showed a pattern more consistent with the depression sensitization model. Finally, comparing across the two samples, stress generation effects were weaker for older participants and for those with more prior MDEs. The complex, multi-factorial relation between stress and depression is discussed. PMID:25422968

Pre-, peri-, and postnatal stress have frequently been reported to be associated with negative health outcomes during adult life. However, it is unclear, if these factors independently predict mental health in adulthood. We estimated potential associations between reports of pre-, peri-, and postnatal stress and depression severity in outpatients (N = 473) diagnosed with depression, anxiety or somatoform disorders by their family physician. We retrospectively assessed pre-, peri-, and postnatal stress and measured depression severity as well as recent life stress using questionnaires. First, we estimated if depression severity was predicted by pre-, peri- and/or postnatal stress using multiple regression models. Second, we compared pre- and postnatal stress levels between patient subgroups of different degrees of depression severity, performing multilevel linear modeling. Third, we analyzed if an association between postnatal stress and current depression severity was mediated by recent life stress. We found no associations of pre-, or perinatal stress with depression severity (all p > 0.05). Higher postnatal stress was associated with higher depression severity (p stress as compared to patients with none to minimal, or mild depression (all p life stress of the association between postnatal stress and depression severity (p stress predicted depression severity in adult life. This association was mediated by recent life stress. Copyright © 2016 Elsevier Ltd. All rights reserved.

The incidence of stroke among younger adults in the United States is increasing. Few studies have investigated the prevalence of depressive symptoms after stroke among different age groups or the extent to which subjective stress at the time of stroke interacts with age to contribute to post-stroke depression. The present study examined whether there exists an age gradient in survivors' level of depressive symptoms and explored the extent to which financial, family, and health-related stress may also impact on depression. Bivariate analyses (N = 322) indicated significant differences in depression and stress by age group, as well as differences in age and stress by 3-month depression status. Linear regression analyses indicated that survivors between the ages of 25-54 and 55-64 years old had, on average, significantly higher depressive symptom scores. Those with financial, family, and health-related stress at the time of stroke, irrespective of age, also had significantly higher scores.

Students in junior high school, particularly in the third level, are prone to a variety of stressors. This in turn might lead to stress, anxiety, depression, and other health-related problems. There are a very limited number of action research studies to identify the effect of stress management techniques among students. Therefore, a study was conducted to assess the effect of a program used in the math class to decrease the student's level of stress, anxiety, and depression. This was an action research study, which was conducted in region three of the Education and Training Office of Isfahan, in the year 2012. Fifty-one students in a junior high school were selected and underwent a comprehensive stress management program. This program was prepared in collaboration with the students, their parents, teachers, and managers of the school, and was implemented approximately during a four-month period. The student's stress, anxiety, and depression were measured before and after the program using the DASS-21 questionnaire. The t-test identified that the mean scores of stress, anxiety, and depression after the intervention were significantly lower than the corresponding scores before the program. One-way analysis of variance (ANOVA) also showed that the students from the veterans (Janbaz) families had higher levels of stress compared to their classmates, who belonged to the non-veteran families (PEducation and implementation of stress management techniques including cognitive and behavioral interventions along with active and collaborative methods of learning in the math class might be useful both inside and outside the class, for better management of stress and other health-related problems of students.

Full Text Available Research on depression and stress has become important because of its high relevance especially in teenage pregnancy. This study aimed to identify the relationship between depression and stress levels and number of stressors faced by 82 first-time pregnant teenagers, who responded to the assessment instruments: Beck Depression Inventory, Perceived Stress Scale and Life Events Questionnaire. According to the results, adolescents who live with their own family are those with the highest means of stress and depression. Therefore, it can be concluded that adolescents who live with their own family are more prone to develop depression and stress during pregnancy, since this could be a contributing factor.

Full Text Available Abstract Introduction: The appearance and evolution of some clinical pain conditions may be influenced by stress and other psychosocial factors. Face, head and cervical muscles may increase their activity and tension in the presence of stress, leading to craniocervicomandibular pain in individuals exposed to stress. Objective: To assess the relationship among perceived stress, anxiety, depression and craniocervicomandibular pain in nursing professionals under stress at work. Materials and Methods: Forty-three women under stress at work, according to the Job Stress Scale (JSS, were assessed by the Perceived Stress Scale (PSS, the Hospital Anxiety and Depression Scale (HADS, pressure pain threshold, measured by algometry, and muscle sensitivity to hand palpation of the masticatory and cervical muscles. Results: A low moderate level of perceived stress was found in 62.79% of the sample, anxiety in 11.63% and depression in 9.30%. The psychosocial scales correlated with each other. No correlation was found between pressure pain threshold and perceived stress, anxiety and depression. The level of pain to hand palpation correlated with the perceived stress scores. Conclusion: Pressure pain threshold was not influenced by the psychosocial factors assessed. Pain intensity to hand palpation, however, was higher as the perception of stress increased.

The purpose of this study is to analyze what aspects of occupational stress predict depression among Korean workers, and determine which components of occupational stress or job characteristics is more strongly associated with depression. In this cross-sectional study, a total of 8,522 workers (21-65 years of age) from a nationwide sample were recruited. A self-administered questionnaire was used to assess socio-demographics, job characteristics, depressive symptoms measured by the Center for Epidemiologic Studies Depression Scale, and occupational stress assessed by the Korean occupational stress scale (KOSS). Multivariate analyses show that inadequate social support (OR = 1.58, 95% CI = 1.52, 1.66) and discomfort in occupational climate (OR = 1.25, 95% CI = 1.18, 1.32) were more important risk factors for depression than organizational injustice, job demand and job control. Compared to the 'business activities' industries, 'recreational, cultural and sporting activities' (OR = 3.45, 95% CI = 1.80, 6.58), 'hotel and restaurants' (OR = 3.34, 95% CI = 1.92, 5.80), 'real estate and renting and leasing' (OR = 2.24, 95% CI = 1.13, 4.44), 'wholesale and retail' (OR = 1.85, 95% CI = 1.28, 2.67), 'transportation' (OR = 1.85, 95% CI = 1.11, 3.07), and 'financial institute and insurance' (OR = 1.60, 95% CI = 1.04, 2.48) industries had significantly greater risk of depression after controlling for gender, age, marital status, duration of employment and all subscale of KOSS. The finding that inadequate social support and discomfort in occupational climate is a better predictor of depressive symptoms than organizational injustice in Korea, indicates that the newly developed KOSS has cultural relevance for assessing occupational stress in Korea. Future studies need to understand factors such as "emotional labor" within certain industries where increased risk for depression is observed.

To compare the psychological impact following early miscarriage between women who conceived naturally and women who conceived following assisted reproduction. Prospective cohort study. Assisted reproduction clinic and general gynaecological unit in a university-affiliated, tertiary referral hospital. A cohort of 150 women (75 after natural conception; 75 after assisted reproduction). Completed semi-structured interviews using two standard questionnaires [the 12-item General Health Questionnaire (GHQ-12) and the 22-item Revised Impact of Events Scale (IES-R)], at 1, 4, and 12 weeks after a diagnosis of first-trimester miscarriage. The GHQ-12 and IES-R scores for the two groups of women. The GHQ-12 and IES-R scores were significantly higher in the assisted reproduction group than the scores in the natural conception group, at 4 weeks and 12 weeks after miscarriage. Further breakdown of the scores revealed significantly higher hyperarousal symptoms at 4 and 12 weeks in the assisted reproduction group, indicating the traumatic effect of miscarriage to these women. Following first-trimester miscarriage, subfertile women who conceived after assisted reproduction had higher stress and anxiety-depression levels, and experienced more traumatic impact from the event, than those after natural conception. A timely support and psychological intervention would be beneficial in the management of this group of women. © 2013 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2013 RCOG.

This study examines results from three mental health screening measures in a cohort of adolescent public school students in seven public schools in Southeast Texas affiliated with the Dating it Safe study. We estimated the odds of receiving professional mental health treatment in the previous year given results from different mental health screening batteries: the CES-D 10 battery for depression screening, the Screen for Child Anxiety Related Disorders, and the Primary Care Posttraumatic Stress Disorder screen. Overall, students with higher scores on screening instruments for depression, posttraumatic stress disorder, and combinations of screening instruments were more likely to have sought past-year professional mental health treatment than non-symptomatic youth. However, the proportion of students screening positive and receiving professional treatment was low, ranging from 11 to 16 %. This study emphasizes the need for broader evaluation of population-based mental health screening among adolescents.
Full Text Available The current study was aimed to investigate the role of 5,7-dimethoxycoumarin in the prevention of chronic mild stress induced depression in rats. The chronic mild stress rat model was prepared using the known protocols. The results from open-field test showed that rats in the chronic mild stress group scored very low in terms of crossings and rearings than those of the normal rats. However, pre-treatment of the rats with 10 mg/kg doses of 5,7-dimethoxycoumarin prevented decline in the locomotor activity by chronic mild stress. The level of monoamine oxidase-A in the chronic mild stress rat hippocampus was markedly higher. Chronic mild stress induced increase in the monoamine oxidase-A level was inhibited by pre-treatment with 10 mg/kg doses of 5,7-dimethoxycoumarin in the rats. Chronic mild stress caused a marked increase in the level of caspase-3 mRNA and proteins in rat hippocampus tissues. The increased level of caspase-3 mRNA and protein level was inhibited by treatment of rats with 5,7-dimethoxycoumarin (10 mg/kg. 5,7-Dimethoxycoumarin administration into the rats caused a marked increase in the levels of heat shock protein-70 mRNA and protein. The levels of heat shock protein-70 were markedly lower both in normal and chronic mild stress groups of rats compared to the 5,7-dimethoxycoumarin treated groups. Thus 5,7-dimethoxycoumarin prevented the chronic mild stress induced depression in rats through an increase in the expression of heat shock protein-70 and inhibition of monoamine oxidase-A levels.

Prostaglandin (PG) D2 is the most abundant prostaglandin in the mammalian brain. The physiological and pharmacological actions of PGD2 in the central nervous system seem to be associated with some of the symptoms exhibited by patients with major depressive disorder. Previous studies have found that PGD2 synthase was decreased in the cerebrospinal fluid of major depressive disorder patients. We speculated that there may be a dysregulation of PGD2 levels in major depressive disorder. Ultra-performance liquid chromatography-tandem mass spectrometry coupled with a stable isotopic-labeled internal standard was used to determine PGD2 levels in the plasma of major depressive disorder patients and in the brains of depressive mice. A total of 32 drug-free major depressive disorder patients and 30 healthy controls were recruited. An animal model of depression was constructed by exposing mice to 5 weeks of chronic unpredictable mild stress. To explore the role of PGD2 in major depressive disorder, selenium tetrachloride was administered to simulate the change in PGD2 levels in mice. Mice exposed to chronic unpredictable mild stress exhibited depression-like behaviors, as indicated by reduced sucrose preference and increased immobility time in the forced swimming test. PGD2 levels in the plasma of major depressive disorder patients and in the brains of depressive mice were both decreased compared with their corresponding controls. Further inhibiting PGD2 production in mice resulted in an increased immobility time in the forced swimming test that could be reversed by imipramine. Decreased PGD2 levels in major depressive disorder are associated with depression-like behaviors. © The Author 2017. Published by Oxford University Press on behalf of CINP.

This study examined the independent and interactive contributions of maternal depression and youth stress responses to trajectories of youth depression in adolescence. Youths (n = 165, M age = 12.43, SD = 1.18) and their maternal caregivers participated in a 4-year longitudinal study. Mothers and youths were administered diagnostic interviews assessing depression, and youths provided reports of their responses to peer stress. Consistent with an interactive model, adaptive responses to stress (high effortful engagement and low involuntary disengagement) buffered the effect of maternal depression on initial levels and trajectories of youth depression, with gender differences emerging. Consistent with a dual-risk model, maternal depression and maladaptive responses to stress (high effortful disengagement and involuntary engagement) contributed additive risks such that youths displayed the highest levels of depression when they were exposed to maternal depression and showed maladaptive stress responses. This research provides novel evidence that responses to stress contribute to individual differences in depression among offspring of depressed mothers, and suggests that responses to stress are an important target for efforts to promote resilience in at-risk youth.

Health-care workers in developed nations are well known to experience high levels of burnout and psychiatric morbidity, but little information is available from the Caribbean and other less well-developed regions. This study sought to explore the prevalence of stress, burnout, and depressive symptoms and associated risk factors among medical students in Trinidad and Tobago, the southernmost Caribbean island. A cross-sectional survey design was used to sample students. Data was collected utilizing standardized questionnaires that assess stress, burnout, and depressive symptoms. Demographic data and information pertaining to potential risk factors was also gathered. Overall, 450 questionnaires were distributed and analysis was performed upon 381 completed surveys (response rate 85%). Students demonstrated high levels of stress and a significant prevalence of burnout (52%) and depressive symptoms (40%). Final year students demonstrated higher levels of burnout and depressive symptoms. Students who (i) felt they lacked emotional support, (ii) had little opportunity for relaxation and exercise, and (iii) did not feel they had control of their daily schedule all demonstrated higher levels of burnout and depressive symptoms. However, students who practiced from a faith base and considered their religion important demonstrated lower levels of both. Medical students in Trinidad and Tobago are experiencing high levels of stress with a large proportion suffering from burnout and depressive symptoms. These data suggest that immediate interventions are necessary to help students cope with the challenges faced during medical school. Additionally, more research is needed to explore the potential causal links between burnout and depression during medical school and the effectiveness of tailored interventions especially within the context of developing nations.

Through stress generation, individuals' own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.

Traumatic injury and mental health disorders are co-associated. Early identification of depression, anxiety and stress following injury, and subsequent preventive intervention, may reduce the long-term symptoms and negative impacts associated with depression and anxiety. The purpose of the study was to determine the incidence, severity and predictors of depression, anxiety and stress in injured patients in the acute phase of care, and at six months following injury, as well as the effectiveness of an in-hospital screening tool. This descriptive longitudinal study of trauma patients was conducted at a Level 1 Metropolitan Trauma Centre in Australia over 14 months. Participants were interviewed using the Depression Anxiety Stress Scale short-form version (DASS-21) during hospital admission then at 3 and 6 months after injury. Descriptive statistics were performed to evaluate participant characteristics and incidence of depression, anxiety and stress. Correlations and logistic regression were conducted to investigate the ability of the DASS-21 to predict symptoms of depression, anxiety and stress and to investigate factors associated with depression, anxiety and stress 6 months after injury. 201 participants ranging in age (18-94 years) and injury severity participated in the baseline interview and 109 completed all 3 interviews over 6 months. Over half (54%) reported above normal scores for depression, anxiety and/or stress in at least one of the 3 time points. Intensive care unit admission and high levels of depression, anxiety and stress at 3 months post injury were predictors for high levels of depression, anxiety and stress at 6 months. Low scores for depression, anxiety and stress during admission were correlated with low scores for depression, anxiety and stress at 3 and 6 months. Depression, anxiety and stress in patients hospitalised following injury is common and should be anticipated in patients who have had an intensive care admission. Screening at 3

The Humulus lupulus L. plant (hops) is used as a herbal medicinal product for anxiety/mood disorders. Our aim was to study the effects of a hops dry extract on self-reported depression, anxiety and stress levels in young adults. Apparently healthy young adults from our university completed the Depression Anxiety Stress Scale-21 (DASS-21) and those reporting at least mild depression, anxiety and stress were invited to complete the study intervention. This followed a randomized (1:1), placebo-controlled, double-blind, crossover design with two 4-week intervention periods (Melcalin hops or placebo; two 0.2 gr capsules once daily) separated by a 2-week wash-out. Anthropometric measurements, DASS-21 assessments and measurements of morning cortisol plasma levels were performed at the beginning and the end of the 4-week treatment periods. 36 participants (Females/Males: 31/5; age: 24.7±0.5 years) completed the study intervention (attrition: 6/42). No significant changes in body weight and composition or morning circulating cortisol were noted with the hops or placebo. Significantly decreased DASS-21 anxiety, depression and stress scores were documented with hops (9.2±7.3 vs. 5.1±5.9, 11.9±7.9 vs. 9.2±7.4, and 19.1±8.1 vs. 11.6±8.1; all p values depression, anxietyand stress symptoms, daily supplementation with a hops dry extract can significantly improve all these symptoms over a 4-week period. These beneficial effects agree with the indication of hops for anxiety/mood disorders and restlessness, as approved by the German Commission E.

To explore the relationship between the depression symptoms and occupational stress in occupational populations. Depression symptoms were measured by using the center for epidemiological survey-depression scale. The occupational stress instrument were employed to investigate the stressors, personalities, social support, and coping strategies as well as the subject's age, length of service, sex, educational level and marriage status. Chi(2) test was used for analyzing the difference of depression. The multiple covariance analysis was used for testing the difference of stressors, personalities, social support, and coping strategies among the groups with different scores of depression. The variables obtained in the optional prediction equation were identified by multiple stepwise regression analysis. The incidence rate of definite depression symptoms was 40.2%. The total average score was 21.74 +/- 8.99. Henan province had the highest incidence rate of depression symptoms, 43.8%, Hebei 39.4%, and Beijing the lowest, 23.4%. The male workers had the higher incidence rate of depression symptoms, 43. 0% than female, 35.4% (P affect the mental health.

Medical students can and do suffer from mental disorders is a concept yet to get wide acceptance. There are few studies comprehensively evaluating depression, stress, and burnout in medical students, especially in a longitudinal way in India. The current study aims to assess the impact of medical education on the development of psychological morbidities and the role of personality. First-year medical students of a leading medical college of India were enrolled on admission and given anonymized, validated, self-administered questionnaires assessing depression, stress, burnout, and personality. This was repeated at the end of 1 st year. Data were analyzed independently as questionnaires were anonymized. We found that 1 st year of medical college showed a significantly increasing depression ( P stress ( P burnout did not increase significantly. However, only disengagement dimension of burnout increased significantly. Personalities with weak capacity to adjust had a significant positive correlation with depression ( r = 0.277, P stress scores ( r = 0.210, P = 0.008). However, burnout did not correlate with any of the personality dimensions. Right from the 1 st year of medical education students perceive high-stress levels and have a high risk of depression. Burnout starts to creep in at least in the form of disengagement. This study provides a sound groundwork for planning interventions to reduce student's mental morbidity and avoid burnout.

Folk illnesses that are cultural constructions of psychological distress offer a vehicle for the cross-cultural study of stress and stress-related morbidity. This study explores the relationship between the Latin American folk illnesses susto and nervios and mental health. We hypothesize that these folk illnesses are distinct and that there is a stronger association between current levels of stress and depressive symptoms with past experience of nervios than with susto, because the cultural constructions of these folk illnesses reflect chronic and acute concepts of distress, respectively. Interviews were conducted in Guadalajara, Mexico, where participants responded to questions about their socio-demographic characteristics, stress, depressive symptoms, and whether they had experienced susto or nervios. Susto and nervios are very prevalent and occur across sociodemographic subgroups, with the exception that nervios occurred more often in women (p nervios had a much stronger association (p nervios were expressions of psychological distress; most of those with depression reported susto and/or nervios. This study validates the link between these folk illnesses and stress and depression and may, ultimately, facilitate cross-cultural research on stress.

Stress and depression consistently elevate inflammation and are often experienced simultaneously, which is exemplified by people in troubled relationships. Troubled relationships also elevate inflammation, which may be partially explained by their ability to engender high levels of stress and depression. People who are stressed, depressed, or in troubled relationships are also at greater risk for health problems than their less distressed counterparts. Inflammation, a risk factor for a variety of age-related diseases including cardiovascular disease, Type II diabetes, metabolic syndrome, and frailty, may be one key mechanistic pathway linking distress to poor health. Obesity may further broaden the health implications of stress and depression; people who are stressed or depressed are often overweight, and adipose tissue is a major source of proinflammatory cytokines. Stress, depression, and troubled relationships may have synergistic inflammatory effects: loneliness, subclinical depression, and major depression enhance inflammatory responses to an acute stressful event. The relationship between distress and inflammation is bidirectional; depression enhances inflammation and inflammation promotes depression. Interesting questions emerge from this literature. For instance, some stressors may be more potent than others and thus may be more strongly linked to inflammation. In addition, it is possible that psychological and interpersonal resources may buffer the negative inflammatory effects of stress. Understanding the links among stress, depression, troubled relationships, and inflammation is an exciting area of research that may provide mechanistic insight into the links between distress and poor health. © 2013 Wiley Periodicals, Inc.

Objective: To investigate the interaction between mental elasticityand occupational stress and depressionin female nurses and the mediating effect of mental elasticity, as well as the functioning way of mental elasticity in occupational stress-depression. Methods: From August to October, 2015, cluster sampling was used to select 122 female nurses in a county-level medical institution as study subjects. The Connor-Davidson Resilience Scale (CD-RISC) , Occupational Stress Inventory-Revised Edition (OSI-R) , and Self-Rating Depression Scale (SDS) were used to collect the data on mental elasticity, occupational stress, and depression and analyze their correlation and mediating effect. Results: The 122 female nurses had a mean mental elasticity score of 62.4±15.1, which was significantly lower than the Chinese norm (65.4±13.9) ( P occupational stress and depression ( r =-0.559 and -0.559, both P Occupational stress and the two subscales mental stress reaction and physical stress reaction were positively correlated with depression ( r =0.774, 0.734, and 0.725, all P occupational stress had a positive predictive effect on depression ( β =0.744, P occupational stress on depression and a significant mediating effect of mental elasticity ( a =-0.527, b =-0.227, c =0.744, c '=0.627; all P occupational stress and depression and can alleviate the adverse effect of occupational stress and reduce the development of depression.

Post-partum stress and depression (PPD) have a significant effect on child development and behavior. Depression is associated with hypercortisolism in humans, and the fluctuating levels of hormones, including corticosterone, during pregnancy and the post-partum, may contribute to PPD. The present study was developed to investigate the effects of high-level corticosterone (CORT) post-partum in the mother on postnatal neurogenesis and behavior in the offspring. Sprague-Dawley dams were treated with either CORT (40 mg/kg) or sesame oil injections daily for 26 days beginning the day after giving birth. Dams were tested in the forced swim test (FST) and in the open field test (OFT) on days 24-26 post-partum. Results showed that the dams exposed to CORT expressed "depressive-like" behavior compared to controls, with decreased struggling behavior and increased immobility in the FST. To investigate the effects of treatment on hippocampal postnatal cell proliferation and survival in the offspring, males and females from treated dams were injected with BrdU (50 mg/kg) on postnatal day 21 and perfused either 24 h (cell proliferation) or 21 days (cell survival) later. Furthermore, male and female offspring from each litter were tested in adulthood on various behavioral tests, including the forced swim test, open field test, resistance to capture test and elevated plus maze. Intriguingly, male, but not female, offspring of CORT-treated dams exhibited decreased postnatal cell proliferation in the dentate gyrus. Both male and female offspring of CORT-treated dams showed higher resistance to capture and greater locomotor activity as assessed in the open field test. As high levels of CORT may be a characteristic of stress and/or depression, these findings support a model of 'CORT-induced' post-partum stress and possibly depression and demonstrate that the offspring of affected dams can exhibit changes in postnatal neurogenesis and behavior in adulthood.

The present study examined stress generation in a developmental and family context among 171 mothers and their preadolescent children, ages 8-12 years, at baseline (Time 1) and 1-year follow-up (Time 2). In the current study, we examined the bidirectional relationship between children's depressive symptoms and dependent family stress. Results suggest that children's baseline level of depressive symptoms predicted the generation of dependent family stress 1 year later. However, baseline dependent family stress did not predict an increase in children's depressive symptoms 1 year later. In addition, we examined whether a larger context of both child chronic strain (indicated by academic, behavioral, and peer stress) and family factors, including socioeconomic status and parent-child relationship quality, would influence the stress generation process. Although both chronic strain and socioeconomic status were not associated with dependent family stress at Time 2, poorer parent-child relationship quality significantly predicted greater dependent family stress at Time 2. Child chronic strain, but neither socioeconomic status nor parent-child relationship quality, predicted children's depression symptoms at Time 2. Finally, gender, maternal depression history, and current maternal depressive symptoms did not moderate the relationship between level of dependent family stress and depressive symptoms. Overall, findings provide partial support for a developmental stress generation model operating in the preadolescent period.

Full Text Available Childhood adversity may lead to depressive relapse through its long-lasting influence on stress sensitivity. In line with the stress sensitization hypothesis, minor (daily stress is associated with depressive relapse. Therefore, we examine the impact of childhood adversity on daily stress and its predictive value on prospectively assessed depressive symptoms in recurrently depressed patients.Daily stress was assessed in recurrently depressed adult patients, enrolled into two randomized trials while remitted. The reported intensity and frequency of dependent and independent daily stress was assessed at baseline. Independent stress is externally generated, for example an accident happening to a friend, while dependent stress is internally generated, for example getting into a fight with a neighbor. Hierarchical regression analyses were performed with childhood adversity, independent and dependent daily stress as predictor variables of prospectively measured depressive symptoms after three months of follow-up (n = 138.We found that childhood adversity was not significantly associated with a higher frequency and intensity of daily stress. The intensity of both independent and dependent daily stress was predictive of depressive symptom levels at follow-up (unadjusted models respectively: B = 0.47, t = 2.05, p = 0.041, 95% CI = 0.02-0.92; B = 0.29, t = 2.20, p = 0.028, 95% CI = 0.03-0.55. No associations were found between childhood adversity and depressive symptoms at follow-up.No evidence was found supporting stress sensitization due to the experience of childhood adversity in this recurrently depressed but remitted patient group. Nevertheless, our research indicates that daily stress might be a target for preventive treatment.Trial A: Nederlands Trial Register NTR1907 Trial B: Nederlands Trial Register NTR2503.

Given the link between youth depression and stress exposure, efforts to identify related biomarkers have involved examinations of stress regulation systems, including the hypothalamic-pituitary-adrenal (HPA) axis. Despite these vast efforts, the underlying mechanisms at play, as well as factors that may explain heterogeneity of past findings, are not well understood. In this study, we simultaneously examined separate components of the HPA-axis response (e.g. activation intensity, peak levels, recovery) to the Socially Evaluated Cold-Pressor Test in a targeted sample of 115 youth (age 9-16), recruited to overrepresent youth with elevated symptoms of depression. Among youth who displayed a cortisol response to the task, depression symptoms were associated with higher peak responses but not greater rate of activation or recovery in boys only. Among those who did not respond to the task, depression symptoms were associated with greater cortisol levels throughout the visit in boys and girls. Results suggest that depression symptoms are associated with a more prolonged activation of the axis and impaired recovery to psychosocial stressors primarily in boys. We discussed two potential mechanistic explanations of the link between depression symptoms and the duration of activation: (1) inhibitory shift (i.e. point at which the ratio of inhibitory and excitatory input into the axis shifts from greater excitatory to greater inhibitory input) or (2) inhibitory threshold (i.e. level of cortisol exposure required to activate the axis' feedback inhibition system).

to understand the trends in, and relationships between, maternal stress, depressive symptoms and anxiety in pregnancy and post partum. a prospective longitudinal survey study was undertaken to explore maternal psychological distress throughout the perinatal period. The participants were recruited after 24 completed weeks of gestation, and were followed-up monthly until one month post partum (four surveys in total). participants were recruited from a single hospital in southern Taiwan, and asked to complete questionnaires in the hospital waiting area. inclusion criteria were: age ≥18 years, able to read and write Chinese, ≥24 weeks of gestation, singleton pregnancy and no pregnancy complications (including a diagnosis of antenatal depression or anxiety disorder). In total, 197 women completed all four surveys (response rate 74.62%). stress was measured with the 10-item Perceived Stress Scale, depressive symptoms were measured with the Center for Epidemiologic Studies' Depression scale, and anxiety was measured with the Zung Self-reported Anxiety Scale. Participants were followed-up at four time points: T1 (25-29 gestational weeks), T2 (30-34 gestational weeks), T3 (>34 gestational weeks) and T4 (4-6 weeks post partum). Appointments for data collection were made in accordance with the participants' antenatal and postnatal check-ups. The three types of maternal distress had different courses of change throughout the perinatal period, as levels of depressive symptoms remained unchanged, anxiety levels increased as gestation advanced but declined after birth, and stress decreased gradually during pregnancy but returned to the T1 level after birth. There was a low to high degree of correlation in maternal stress, depressive symptoms and anxiety in pregnancy and post partum. around one-quarter of the study participants had depressive symptoms during pregnancy and post partum. Stress and anxiety showed opposing courses during the perinatal period. Regardless of the

Insomnia-type sleep disturbances are frequent among patients suffering from stress-related exhaustion disorder. However, clinical observations indicate that a subgroup suffer from sleep lengths frequently exceeding 9 hours, coupled with great daytime sleepiness. The aim of the present study was to investigate differences in socio-demographic variables, use of medications, sleep parameters, anxiety, depression and fatigue, between individuals with varying sleep lengths, in a sample of 420 Swedish patients (mean age 42 ± 9 years; 77% women) referred to treatment for exhaustion disorder. Patients were allocated to the groups: "never/seldom ≥ 9 hours" (n = 248), "sometimes ≥ 9 hours" (n = 115) and "mostly/always ≥ 9 hours" (n = 57), based on their self-rated frequency of sleep lengths ≥ 9 hours. The design was cross-sectional and data was collected by means of questionnaires at pre-treatment. Univariate analyses showed that patients in the "mostly/always ≥ 9 hours" group were more often on sick leave, and reported more depression and fatigue, better sleep quality and more daytime sleepiness, than patients in the other groups. Multivariate analyses showed that these patients scored higher on measures of fatigue than the rest of the sample independently of gender, use of antidepressants, sick leave, depression and quality of sleep. Patients suffering from exhaustion disorder and reporting excessive sleep seem to have a generally poorer clinical picture but better quality of sleep than their counterparts with shorter sleep lengths. The mechanisms underlying these differences, together with their prognostic value and implications for treatment remain to be elucidated in future studies.

This study examines the moderating role of dispositional optimism on the relationship between perceived stress and depression of the Chinese "Ant Tribe." A total of 427 participants from an Ant Tribe community completed the measures of perceived stress, optimism, and depression. The structural equation modeling (SEM) analysis showed that dispositional optimism moderated the association between perceived stress and depression. The Ant Tribe with high perceived stress reported higher scores in depression than those with low perceived stress at low dispositional optimism level. However, the impact of perceived stress on depression was insignificant in the high dispositional optimism group. © The Author(s) 2015.

Telemental health (TMH) resources are plentiful; however, we know little about college students' opinions about such resources. We aimed to examine students' previous use of and willingness to use several types of TMH resources. Students (N = 662) from two U.S. Midwestern colleges participated. Using an online survey in spring 2017, we measured students' depression, anxiety, stress, and suicidal thoughts, preferences for care options during distress, and use and interest in anonymous chats with trained nonprofessionals, online therapy, and self-help resources. Overall, 10.1-13.8% had experience with these TMH resources; however, 24.6-40.1% expressed willingness to try them. At-risk students, especially those higher in depression/anxiety scores, showed greater use of and willingness to use some applications. Counseling centers might consider endorsing TMH resources as potential pathways to care. TMH resources might help broaden reach with minimal cost, reduce mental health help-seeking barriers, and provide support to at-risk populations.

Oxidative stress has been implicated in the pathophysiology of mood disorders in young adults. However, there is few data to support its role in the elderly. The primary aim of this study was to evaluate whether subjects with late-life depression (LLD) presented with changes in oxidative stress response in comparison with the non-depressed control group. We then explored how oxidative stress markers associated with specific features of LLD, in particular cognitive performance and age of onset of major depressive disorder in these individuals. We included a convenience sample of 124 individuals, 77 with LLD and 47 non-depressed subjects (Controls). We measure the plasma levels of 6 oxidative stress markers: thiobarbituric acid reactive substances (TBARS), protein carbonil content (PCC), free 8-isoprostane, glutathione peroxidase (GPx) activity, glutathione reductase (GR) activity, and glutathione S-transferase (GST) activity. We found that participants with LLD had significantly higher free 8-isoprostane levels (p = 0.003) and lower glutathione peroxidase activity (p = 0.006) compared to controls. Free 8-isoprostane levels were also significantly correlated with worse scores in the initiation/perseverance (r = -0.24, p = 0.01), conceptualization (r = -0.22, p = 0.02) sub-scores, and the total scores (r = -0.21, p = 0.04) on the DRS. Our study provides robust evidence of the imbalance between oxidative stress damage, in particular lipid peroxidation, and anti-oxidative defenses as a mechanism related to LLD, and cognitive impairment in this population. Interventions aiming to reduce oxidative stress damage can have a potential neuroprotective effect for LLD subjects. Copyright © 2018 Elsevier Ltd. All rights reserved.

Negative inferential style and deficits in emotional clarity have been identified as vulnerability factors for depression in adolescence, particularly when individuals experience high levels of life stress. However, previous research has not integrated these characteristics when evaluating vulnerability to depression. In the present study, a racially diverse community sample of 256 early adolescents (ages 12 and 13) completed a baseline visit and a follow-up visit 9 months later. Inferential style, emotional clarity, and depressive symptoms were assessed at baseline, and intervening life events and depressive symptoms were assessed at follow-up. Hierarchical linear regressions indicated that there was a significant three-way interaction between adolescents' weakest-link negative inferential style, emotional clarity, and intervening life stress predicting depressive symptoms at follow-up, controlling for initial depressive symptoms. Adolescents with low emotional clarity and high negative inferential styles experienced the greatest increases in depressive symptoms following life stress. Emotional clarity buffered against the impact of life stress on depressive symptoms among adolescents with negative inferential styles. Similarly, negative inferential styles exacerbated the impact of life stress on depressive symptoms among adolescents with low emotional clarity. These results provide evidence of the utility of integrating inferential style and emotional clarity as constructs of vulnerability in combination with life stress in the identification of adolescents at risk for depression. They also suggest the enhancement of emotional clarity as a potential intervention technique to protect against the effects of negative inferential styles and life stress on depression in early adolescence.

Ayurveda (Indian-complimentary and alternative medicine) is still most sought after in India and has promising potential in management of Vishada [major depressive disorder (MDD)]. But, systematic research is lacking. In this study we evaluated of influence of ayurvedic treatment (Panchakarma and Ayushman-15) on psychopathology, heart rate variability (HRV) and endocrinal parameters in patients with major depression. 81 drug naive patients diagnosed as Vishada by ayurvedic physician and MDD according to DSM IV-TR were given ayurvedic Virechana module (therapeutic purgation) and were randomized into two groups. Patients in group A (n=41) received Ayushman-15A while group B (n=40) received Ayushman-15B for two months and Shirodhara (forehead-oil pouring therapy). Patients were assessed with Hamilton Depression Rating Scale (HDRS), Montgomery Asberg Depression Rating Scale (MADRS), Heart Rate Variability (HRV). Cortisol and adrenocorticotropic hormone (ACTH) were estimated at baseline and after ayurvedic therapy. HRV and endocrinal parameters were compared with age and gender matched healthy volunteers. HRV parameters showed significant sympathetic dominance in patients compared to healthy volunteers. Two months of ayurvedic treatment significantly decreased psychopathology, showed increase in vagal tone, decrease in sympathetic tone and reduced cortisol levels. However, there was no significant difference between groups receiving Ayushman A and B. This study provides evidence for antidepressant, cardiac (HRV) and beneficial neuroendocrine modulatory influence of Ayurveda therapy in patients of Vishada (MDD). Further studies are needed to confirm these findings. Greater insight into the neurobiology behind this therapy might provide valuable information about newer drug target.

Full Text Available Introduction: Aging is a natural process in individuals. Most of the elderly have problems in dealing with this natural process. Lost of occupation, friends and loneliness may result in depression in this age group. Cognitive therapy changes pessimistic idea, unrealistic hopes and excessive self evaluation may result and justify depression. Cognitive therapy may help elderly to recognize the problem in life, to develop positive objective of life and to create more positive personality. The aimed of this study was to analyze the effect of cognitive therapy to reduce the level of depression. Method: This study was used a pre experimental pre post test design. Sample were 10 elderly people who met to the inclusion criteria. The independent variable was cognitive therapy and dependent variable was the level of depression in elderly. Data were collected by using Geriatric Depression Scale (GDS 15, then analyzed by using Wilcoxon Signed Rank Test with significance levelα≤0.05. Result: The result showed that cognitive therapy has an effect on reducing depression with significance level p=0.005. Discussion: It can be concluded that cognitive therapy was effective in reducing depression level in elderly. Further studies are recommended to analyze the effect of cognitive therapy on decreasing anxiety in elderly by measuring cathecolamin.

The objective of this study was to find risk factors in pregnancy for post-traumatic stress and depression 1 month after childbirth. Furthermore, the relation between post-traumatic stress and depression was explored. A prospective longitudinal study. Pregnant women in Linköping and Kalmar, Sweden. A total of 1224 women were assessed in pregnancy, week 12-20 and 32, as well as 1 month postpartum. Post-traumatic stress and depression after delivery were assessed 1 month postpartum. Potential risk factors were assessed in early and late pregnancy. Variables measured during pregnancy were trait anxiety, depression, fear of childbirth, childbirth-related traumatic stress, stress coping capacity, social support, parity, educational level, age, gestation week, parity, educational level, civil status, previous psychological/psychiatric counselling, and previous experience of any traumatic events. Delivery mode was assessed from the medical records. Prevalence of post-traumatic stress (criteria A, B, C, D, E, and F according to DSM-IV) and depression (Beck's depression inventory). One month postpartum, 12 (1.3%) women had post-traumatic stress (met symptom criteria B, C, and D for post-traumatic stress disorder according to Diagnostic and statistical manual of mental disorders, 4th edition [DSM-IV]). The most important risk factors in pregnancy were depression in early pregnancy (OR=16.3), severe fear of childbirth (OR=6.2), and 'pre'-traumatic stress (in view of the forthcoming delivery) in late pregnancy (OR=12.5). The prevalence of depression was 5.6%. Post-traumatic stress and depression were positively related 1 month postpartum and were predicted by mainly the same factors. Risk factors for post-traumatic stress and depression after childbirth can be assessed in early pregnancy. Post-traumatic stress and depression also seem to share the same underlying vulnerability factors.

Suicide occurs in some, but not all depressed patients. So far, it remains unknown whether the studied stress-related candidate genes change in depression, suicide or both. The prefrontal cortex (PFC) is involved in, among other things, impulse control and inhibitory behavior and plays an important role in both suicide and depression. We have employed qPCR to study 124 anterior cingulate cortex (ACC) and dorsolateral PFC (DLPFC) brain samples, obtained from two brain banks, from: i) young depressed patients (average age 43 years) who committed suicide (MDD-S) and depressed patients who died from causes other than suicide (MDD-NS) and from ii) elderly depressed patients (average age 75 years) who did not commit suicide (DEP). Both cohorts were individually matched with non-psychiatric non-suicide control subjects. We determined the transcript levels of hypothalamic-pituitary-adrenal axis-regulating molecules (corticotropin-releasing hormone (CRH), CRH receptors, CRH binding protein, mineralocorticoid receptor/glucocorticoid receptor), transcription factors that regulate CRH expression, CRH-stimulating cytokines, chaperone proteins, retinoid signaling, brain-derived neurotrophic factor and tropomyosin-related kinase B, cytochrome proteins, nitric oxide synthase (NOS) and monoamines. In the MDD-S group, expression levels of CRH and neuronal NOS-interacting DHHC domain-containing protein with dendritic mRNA (NIDD) were increased. Other changes were only present in the DEP group, i.e. decreased NIDD, and increased and 5-hydroxytryptamine receptor 1A (5-HT1A) expression levels. Changes were found to be more pronounced in the anterior cingulate cortex than in the dorsolateral PFC. Depressed patients who committed suicide have different gene expression patterns than depressed patients who died of causes other than suicide. Copyright © 2015 Elsevier Ltd. All rights reserved.

Anxiety, stress, and depression affect the use of health care services, treatment decision-making, and responses to periodontal treatment. This study explored periodontists' confidence in detecting patient anxiety, stress, or depression, as well as their knowledge concerning the relationships between these factors and patients' pain, use of pain medication, and wound healing after periodontal treatment. In addition, this research surveyed if (and which) special accommodations were offered when treating patients with high levels of anxiety, stress, or depression. Data were collected from 171 members of the American Academy of Periodontology (response rate = 34.41%). Most respondents were male (82.2%), white (88.2%), and practiced in solo practices (60.9%). The respondents were more knowledgeable about the effects of anxiety and stress on pain, the use of pain medication, and wound healing than about the impact of depression on these outcomes. They agreed more strongly with statements that they were more confident in their ability to perceive when patients were anxious and stressed than when they were depressed. They also offered more special accommodations for patients with anxiety and stress than for patients with depression. The respondents were significantly less knowledgeable about the impact of depression on patients' responses to periodontal treatment than about the effect of anxiety and stress. Given the evidence concerning the relationships among depression, pain, pain medication use, and wound healing, it is important to educate periodontists about the role of anxiety and stress and the significance of depression on their patients' responses to periodontal therapy.

This article aims to assess the levels of stress and symptoms of depression among Danish medical students, as well as explore the effect of social support on psychological distress. The results are based on numbers from the follow-up study 'From Student to Graduate' (j.nr 2006-41-6876). Two dimensions of stress, frequency and perception, were measured on a scale from 0-6. Odds ratios and significance of associations between the various exposure variables and the outcome measure, symptoms of depression, were calculated using multiple logistic regression and Wald tests. 30.5% of the students reported depressive symptoms. Stress frequency measured a mean of 2.26 (SD = 1.35). The mean for stress perception was 2.85 (SD = 1.30). Women reported higher levels of stress and depression compared to male medical students, but the differences were not significant (p > 0.05). Only the dimensions of stress and coping alone were significantly associated with reporting symptoms of depression (p Stress levels were moderate, but significantly associated with symptoms of depression. The interaction between the stress dimensions and the outcome measure illustrates the importance of stress appraisal. Coping alone with psychological problems was significantly associated with symptoms of depression.
It is believed that depression will be the number one cause of disability worldwide in the year 2020, and stress will be a contributing factor. This is significant for South Africa which is considered to be one of the most highly stressed societies in the world with many social problems that contribute to stress and depression.

Appropriately estimating stress levels in daily life is important for motivating people to undertake stress-management behaviors or seek out information on stress management and mental health. People who exhibit high stress underestimation might not be interested in information on mental health, and would therefore have less knowledge of it. We investigated the association between stress underestimation tendency and mental health literacy of depression (i.e., knowledge of the recognition, prognosis, and usefulness of resources of depression) in Japanese workers. We cross-sectionally surveyed 3718 Japanese workers using a web-based questionnaire on stress underestimation, mental health literacy of depression (vignettes on people with depression), and covariates (age, education, depressive symptoms, income, and worksite size). After adjusting for covariates, high stress underestimation was associated with greater odds of not recognizing depression (i.e., choosing anything other than depression). Furthermore, these individuals had greater odds of expecting the case to improve without treatment and not selecting useful sources of support (e.g. talk over with friends/family, see a psychiatrist, take medication, see a counselor) compared to those with moderate stress underestimation. These relationships were all stronger among males than among females. Stress underestimation was related to poorer mental health literacy of depression. Copyright © 2018 Elsevier B.V.

Major depressive disorder (MDD) is often precipitated by life stress and growing evidence suggests that stress-induced alterations in reward processing may contribute to such risk. However, no human imaging studies have examined how recent life stress exposure modulates the neural systems that underlie reward processing in depressed and healthy individuals. In this proof-of-concept study, 12 MDD and 10 psychiatrically healthy individuals were interviewed using the Life Events and Difficulties Schedule (LEDS) to assess their perceived levels of recent acute and chronic life stress exposure. Additionally, each participant performed a monetary incentive delay task under baseline (no-stress) and stress (social-evaluative) conditions during functional MRI. Across groups, medial prefrontal cortex (mPFC) activation to reward feedback was greater during acute stress versus no-stress conditions in individuals with greater perceived stressor severity. Under acute stress, depressed individuals showed a positive correlation between perceived stressor severity levels and reward-related mPFC activation (r=0.79, p=0.004), whereas no effect was found in healthy controls. Moreover, for depressed (but not healthy) individuals, the correlations between the stress (r=0.79) and no-stress (r=-0.48) conditions were significantly different. Finally, relative to controls, depressed participants showed significantly reduced mPFC gray matter, but functional findings remained robust while accounting for structural differences. Small sample size, which warrants replication. Depressed individuals experiencing greater recent life stress recruited the mPFC more under stress when processing rewards. Our results represent an initial step toward elucidating mechanisms underlying stress sensitization and recurrence in depression. Copyright © 2015 Elsevier B.V. All rights reserved.

This study investigated whether overgeneral autobiographical memory (OGM) predicts the course of depression in adolescents. As part of a larger longitudinal study of risk for emotional disorders, 55 adolescents with a past history of major depressive disorder or minor depressive disorder completed the Autobiographical Memory Test. Fewer specific memories predicted the subsequent onset of a major depressive episode (MDE) over a 16-month follow-up period, even when covarying baseline depressive symptoms. This main effect was qualified by an interaction between specific memories and chronic interpersonal stress: Fewer specific memories predicted greater risk of MDE onset over follow-up at high (but not low) levels of chronic interpersonal stress. Thus, our findings suggest that OGM, in interaction with chronic interpersonal stress, predicts the course of depression among adolescents, and highlight the importance of measuring interpersonal stress in OGM research. © 2010 Psychology Press, an imprint of the Taylor & Francis Group, an Informa business

Some adolescents exhibit resilience even in the face of high levels of stress exposure. Despite this relationship, studies that investigate explanations for how resilience interacts with risk to produce particular outcomes and why this is so are lacking. The effect of resilience across the relationship between stress and symptoms of anxiety and stress and symptoms of depression was tested to provide explanations for how resilience interacts with stress and symptoms of anxiety, and depression. In a cross-sectional survey, 533 Ghanaian adolescents aged 13-17 years (M=15.25, SD=1.52), comprising 290 girls and 237 boys completed the Resilience Scale for Adolescents, Adolescent Stress Questionnaire, Spielberger State Anxiety Inventory, and Short Mood Feeling Questionnaire. Mediation and moderation analyses were conducted. The results indicated that resilience partially mediated the relationship between stress, and symptoms of anxiety, and depression. Effects of stress were negatively associated with resilience, and positively associated with symptoms of anxiety and depression. In a differential moderator effect, resilience moderated the relationship between stress and symptoms of depression but not stress and symptoms of anxiety. Although the findings in this study are novel, they do not answer questions about protective mechanisms or processes. Evidence that resilience did not have the same effect across stress, and symptoms of anxiety and depression may support resilience as a dynamic process model. Access to different levels of resilience shows that enhancing resilience while minimizing stress may improve psychiatric health in adolescents' general population. Copyright © 2016 Elsevier B.V.

This study examined the role of stress in the association among physical activity, obesity, and depression among women. The extent to which physical activity moderated these relationships was also examined. Data from the National Survey of American Life (N = 3235) and multivariable regression analyses were used to examine the effects of chronic stress, material hardship, racial discrimination, and physical activity on obesity and depression among African American, Caribbean Black and White women. Stress was not related to body mass index (BMI) for African American or White women, but chronic stress was associated with higher BMI for Caribbean Black women. Stress was associated with depressive symptoms, but there was variation by the type of stressor under consideration. Physical activity was associated with fewer depressive symptoms and lower BMI, but the relationships varied by type of stressor and race/ethnicity. Physical activity moderated the effect of chronic stress on depressive symptoms and BMI, but only for African American women who reported high levels of chronic stress. Among White women, physical activity moderated the effect of racial discrimination on BMI for those who reported experiencing both high and low levels of discrimination. This study was the first to document physical activity as a moderator in the relationship among stress, depression, and obesity using a nationally representative sample of racially/ethnically diverse women. Findings provide insight into the role of stress in relation to depression and obesity while highlighting heterogeneity among Black Americans.

The military is a unique occupational group and, because of this, military personnel face different kinds of stress than civilian populations. Sleep problems are an example. The purpose of this study was to investigate the relationship between sleep problems, depression level and coping strategies among military personnel. In this cross-sectional study, military personnel completed the Beck Depression Inventory, the Pittsburgh Sleep Quality Index and the Jalowiec Coping Scale. An evaluation of the test scores showed that officers had better sleep quality and fewer depressive symptoms than enlisted personnel. Military personnel with higher educational levels and less physical illness also had fewer depressive symptoms. Officers and noncommissioned officers preferred problem-focused strategies. Those with higher Beck Depression Inventory and Pittsburgh Sleep Quality Index scores and those who drank alcohol frequently preferred affective-focused strategies. Our results revealed that sleep quality, physical illness and alcohol consumption were associated with the mental health of military personnel. Treating these factors may improve the mental health of military personnel and enhance effective coping strategies. Copyright © 2016 Southern Society for Clinical Investigation.

This study examined the effect of intrinsic academic motivation and interpersonal conflict on the perceived depression and stress. Participants were 537 Chinese undergraduate students (191 males and 346 females; M age = 20.4 years, SD age = 1.3). They completed four scales measuring intrinsic academic motivation, interpersonal conflict, stress, and depression. Linear regressions were conducted with intrinsic academic motivation, interpersonal conflict, and their interaction as independent variables to predict depression and stress. Results showed that intrinsic academic motivation was negatively, while interpersonal conflict was positively, associated with depression and stress. Moreover, the interaction was significant: negative association of "intrinsic academic motivation and depression" and that of "intrinsic academic motivation and stress" was weaker among participants who reported higher (vs. lower) levels of interpersonal conflict. © The Author(s) 2016.

The refugees were asked about preventive and risk factors that occurred before and after their immigration. Subjects and methods: The sample comprised 55 children and adolescents (30 males and 25 females who were Yazidi refugees and had settled in the Uçkuyular, Oğuz, Onbaşi, and Uğurca villages of Batman, Turkey. The study was conducted 9 months after the refugees had immigrated. The participants were evaluated in their native language through a semistructured interview titled “Reliability and Validity of Schedule for Affective Disorders and Schizophrenia for School-Age Children – Present and Lifetime Version – Turkish Version”. A sociodemographic form was prepared so that investigators could understand their traumatic experiences before and after the migration and their current social conditions. All the interviews were conducted in the participants’ native language without the help of translators. The investigators filled out the sociodemographic forms. Results: Posttraumatic stress disorder (PTSD was detected in 20 children (36.4%, depression in 18 (32.7%, nocturnal enuresis in six (10.9%, and anxiety in four (7.3%. The following factors were found to be associated with depression: witnessing violence and/or death, being a girl, having older parents, being the elder child, and having multiple siblings (P<0.05. Risk factors for PTSD, depression, and comorbid conditions included witnessing violence and/or death (P<0.05. Four participants were observed to have both PTSD and

The 2015 National Health and Morbidity Survey estimated that over 29% of the adult population of Malaysia suffers from mental distress, a nearly 3-fold increase from the 10.7% estimated by the NHMS in 1996 pointing to the potential beginnings of a public health crisis. This study aimed to better understand this trend by assessing depressive symptoms and their correlates in a cross-section of Malaysians. Specifically, it assesses stress, perceived locus of control, and various socio-demographic variables as possible predictors of depressive symptoms in the Malaysian context. A total of 728 adults from three Malaysian states (Selangor, Penang, Terengganu) completed Beck’s depression inventory as well as several other measures: 10% of respondents reported experiencing severe levels of depressive symptoms, 11% reported moderate and 15% reported mild depressive symptoms indicating that Malaysians are experiencing high levels of emotional distress. When controlling for the influence of other variables, depressive symptoms were predictably related to higher levels of stress and lower levels of internal locus of control. Ethnic Chinese Malaysians, housewives and those engaged in professional-type occupations reported less depressive symptoms. Business owners reported more depressive symptoms. Further research should look more into Malaysians’ subjective experience of stress and depression as well as explore environmental factors that may be contributing to mental health issues. It is argued that future policies can be designed to better balance individual mental health needs with economic growth. PMID:28878710

This study was designed to investigate associations among five factor personality traits, perceived stress, and depressive symptoms and to examine the roles of personality and perceived stress in the relationship between gender and depressive symptoms. The participants (N = 3,950) were part of a cohort study for health screening and examination at the Kangbuk Samsung Hospital. Personality was measured with the Revised NEO Personality Inventory (NEO-PI-R). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D). Perceived stress level was evaluated with a self-reported stress questionnaire developed for the Korea National Health and Nutrition Examination Survey. A higher degree of neuroticism and lower degrees of extraversion, agreeableness, and conscientiousness were significantly associated with greater perceived stress and depressive symptoms. Neuroticism and extraversion had significant direct and indirect effects (via stress as a mediator) on depressive symptoms in both genders. Agreeableness and conscientiousness had indirect effects on depression symptoms in both genders. Multiple mediation models were used to examine the mediational roles of each personality factor and perceived stress in the link between gender and depressive symptoms. Four of the personality factors (except openness) were significant mediators, along with stress, on the relationship between gender and depressive symptoms. Our findings suggest that the links between personality factors and depressive symptoms are mediated by perceived stress. As such, personality is an important factor to consider when examining the link between gender and depression.

Stress and fatigue are common complaints of pregnant and postpartum women as is depression. These symptoms may be related to immunomodulation. However, few studies have examined these relationships. The aim of this study was to examine the relationships among stress, fatigue, depression, and cytokines as markers of immune modulation in prenatal and postpartum women. Women completed questionnaires and gave blood samples during late pregnancy and again at 4-6 weeks postpartum. Blood was analyzed for cytokines as measures of immune modulation. Stress, fatigue, and depression were experienced at moderately high levels, with higher levels of fatigue and depression in the postpartum but higher stress in the prenatal period. Levels of several cytokines were increased in the postpartum over the prenatal period. Stress and depression were related in the prenatal period and stress, depression, and fatigue were related in the postpartum. While various cytokines were related to each other in both periods, only stress was related to MIP-1β, a cytokine that may be important for childbirth processes. More studies, especially longitudinal and interventional studies, are needed to increase our knowledge about etiology, patterns, symptoms, factors, and management of maternal distress. The search for reliable biomarkers for at-risk mothers remains a priority.

To examine how cardiorespiratory fitness and self-perceived stress are associated with burnout and depression. To determine if any relationship between stress and burnout/depression is mitigated among participants with high fitness levels. 197 participants (51% men, mean age=39.2 years) took part in the study. The Åstrand bicycle test was used to assess cardorespiratory fitness. Burnout was measured with the Shirom-Melamed Burnout Questionnaire (SMBQ), depressive symptoms with the Hospital Anxiety and Depression Scale (HAD-D). A gender-matched stratified sample was used to ensure that participants with varying stress levels were equally represented. Participants with moderate and high fitness reported fewer symptoms of burnout and depression than participants with low fitness. Individuals with high stress who also had moderate or high fitness levels reported lower scores on the SMBQ Tension subscale and the HAD-D than individuals with high stress, but low fitness levels. Better cardiovascular fitness seems to be associated with decreased symptoms of burnout and a better capacity to cope with stress. Promoting and measuring cardiorespiratory fitness can motivate employees to adopt a more physically active lifestyle and thus strengthen their ability to cope with stress exposure and stress-related disorders.

The aim of this study was to explore differences in the intensity of depressiveness, sleep disturbances and sleepiness between post-traumatic stress disorder (PTSD) patients and patients with depression. A total of 170 patients were examined, including 120 PTSD patients and 50 patients with depression. All participants completed the Beck Depression Inventory, Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale. The results showed difference in the subjective assessment of sleep quality between the war veterans with PTSD and civilians with depression, without significant differences between them in the level of depressiveness and sleepiness. Considering the fact that insomnia can occur as an early, covert sign of both PTSD and depression and that differences in the intensity of sleep disturbances between the groups were established, the use of these and similar instruments for the assessment of sleep quality can be useful in distinguishing patients with PTSD and depression, treatment of their sleep disturbances, and prevention of more severe symptoms in both diagnostic categories.

Alexithymia is an important predictor of mobile phone addiction. Enhancing and improving college students' mental health can reduce the rate of mobile phone addiction. However, it is not clear about the role of depression, anxiety and stress in the relationship between college students' alexithymia and mobile phone addiction. A total of 1105 college students were tested with the Toronto Alexithymia Scale, the Depression Anxiety Stress Scale and the Mobile Phone Addiction Index. An individual's level of alexithymia was significantly correlated with depression, anxiety, stress and mobile phone addiction. Alexithymia had a significantly positive prediction effect on mobile phone addiction, and depression, anxiety, and stress on mobile phone are positive predictors. Depression, anxiety or stress had partially mediating effects between alexithymia and mobile phone addiction. Alexithymia not only directly had a positively impact on mobile phone addiction, but both also had an indirect effect on mobile phone addiction through depression, anxiety or stress. Limitations included sampling method and modest sample size, self-report measures, and unmeasured potential confounders. Alexithymia is an important correlate of mobile phone addiction, and depression, anxiety or stress is an important mediator in this relationship. Copyright © 2017 Elsevier B.V. All rights reserved.

Recent research indicates that young adult college students experience increased levels of depression, anxiety, and stress. It is less clear what strategies college health care providers might use to assist students in decreasing these mental health concerns. In this paper, we examine the relative importance of coping style, life satisfaction, and selected demographics in predicting undergraduates' depression, anxiety, and stress. A total of 508 full-time undergraduate students aged 18-24 years completed the study measures and a short demographics information questionnaire. Coping strategies and life satisfaction were assessed using the Brief COPE Inventory and an adapted version of the Brief Students' Multidimensional Life Satisfaction Scale. Depression, anxiety, and stress were measured using the Depression Anxiety and Stress Scale-21 (DASS-21). Multiple regression analyses were used to examine the relative influence of each of the independent variables on depression, anxiety, and stress. Maladaptive coping was the main predictor of depression, anxiety, and stress. Adaptive coping was not a significant predictor of any of the three outcome variables. Reducing maladaptive coping behaviors may have the most positive impact on reducing depression, anxiety, and stress in this population.

High levels of stress and deteriorating mental health among medical students are commonly reported. In Bergen, Norway, we explored the impact of personality traits measured early in their curriculum on stress reactions and levels of depression and anxiety symptoms as junior physicians following graduation. Medical students (n = 201) from two classes participated in a study on personality traits and mental health early in the curriculum. A questionnaire measuring personality traits (Basic Character Inventory (BCI)) was used during their third undergraduate year. BCI assesses four personality traits: neuroticism, extroversion, conscientiousness and reality weakness. Questionnaires measuring mental health (Hospital Anxiety and Depression Scale (HADS) and Symptom Checklist 25 (SCL-25)), and stress (Perceived Medical School Stress (PMSS)) were used during their third and sixth undergraduate year. During postgraduate internship, Cooper's Job Stress Questionnaire (CJSQ) was used to measure perceived job stress, while mental health and stress reactions were reassessed using HADS and SCL-25. Extroversion had the highest mean value (5.11) among the total group of participants, while reality weakness had the lowest (1.51). Neuroticism and reality weakness were related to high levels of perceived job stress (neuroticism r = .19, reality weakness r = .17) as well as higher levels of anxiety symptoms (neuroticism r = .23, reality weakness r = .33) and symptoms of depression (neuroticism r = .21, reality weakness r = .36) during internship. Neuroticism indirectly predicted stress reactions and levels of depression and anxiety symptoms. These relations were mediated by perceived job stress, while reality weakness predicted these mental health measures directly. Extroversion, on the other hand, protected against symptoms of depression (r = -.20). Furthermore, females reported higher levels of job stress than males (difference = 7.52). Certain personality traits measured early in

To perform a systematic review and meta-analysis that quantitatively tests and summarizes the hypothesis that depression results in elevated oxidative stress and lower antioxidant levels. We performed a meta-analysis of studies that reported an association between depression and oxidative stress and/or antioxidant status markers. PubMed and EMBASE databases were searched for articles published from January 1980 through December 2012. A random-effects model, weighted by inverse variance, was performed to pool standard deviation (Cohen's d) effect size estimates across studies for oxidative stress and antioxidant status measures, separately. Twenty-three studies with 4980 participants were included in the meta-analysis. Depression was most commonly measured using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria. A Cohen's d effect size of 0.55 (95% confidence interval = 0.47-0.63) was found for the association between depression and oxidative stress, indicating a roughly 0.55 of 1-standard-deviation increase in oxidative stress among individuals with depression compared with those without depression. The results of the studies displayed significant heterogeneity (I(2) = 80.0%, p < .001). A statistically significant effect was also observed for the association between depression and antioxidant status markers (Cohen's d = -0.24, 95% confidence interval = -0.33 to -0.15). This meta-analysis observed an association between depression and oxidative stress and antioxidant status across many different studies. Differences in measures of depression and markers of oxidative stress and antioxidant status markers could account for the observed heterogeneity. These findings suggest that well-established associations between depression and poor heath outcomes may be mediated by high oxidative stress.

Depression, anxiety, and stress are prevalent in patients with musculoskeletal pain, but the impact of these emotional states has not been evaluated in people with plantar heel pain. The aim of this study was to evaluate the association between depression, anxiety, and stress with plantar heel pain. Forty-five participants with plantar heel pain were matched by sex and age (±2 years) to 45 participants without plantar heel pain. Levels of depression, anxiety, and stress were measured using the Depression, Anxiety and Stress Scale (short version) in participants with and without plantar heel pain. Logistic regression was conducted to determine if levels of depression, anxiety, or stress were associated with having plantar heel pain. Univariate analysis indicated that participants with plantar heel pain had greater levels of depression (mean difference = 4.4, 95% CI 2.3 to 6.5), anxiety (mean difference = 2.6, 95% CI 0.9 to 4.3), and stress (mean difference = 4.8, 95% CI 1.9 to 7.8). After adjusting for age, sex, BMI, and education, for every 1 unit increase in depression, anxiety, or stress (in the DASS subscales), the odds ratios for having plantar heel pain were increased by 1.3 (95% CI 1.1 to 1.6), 1.3 (95% CI 1.1 to 1.5), and 1.2 (95% CI 1.1 to 1.3), respectively. Symptoms of depression, anxiety, and stress were independently associated with plantar heel pain. Larger prospective studies are necessary to evaluate the temporal association between these emotional states and plantar heel pain. Level III, cross sectional, observational. © The Author(s) 2016.

We recently demonstrated that exposure to early life stress exacerbates nerve injury-induced thermal and mechanical hypersensitivity in adult male and female mice. Accumulating evidence suggests that chronic pain causes emotional dysfunction, such as anxiety and depression. In the present study, we investigated the impact of early life stress on depression-like behavior after nerve injury in mice. In addition, we examined the expression of brain-derived neurotrophic factor (BDNF), which is known to be involved in the pathogenesis of depression. Early life stress was induced by maternal separation between 2 and 3 weeks of age combined with social isolation after weaning (MSSI). At 9 weeks of age, the sciatic nerve was partially ligated to elicit neuropathic pain. Depression-like behavior was evaluated using the forced swim test at 12 weeks of age. Tissue samples from different regions of the brain were collected at the end of maternal separation (3 weeks of age) or after the forced swim test (12 weeks of age). At 12 weeks of age, immobility time in the forced swim test was increased only in MSSI-stressed female mice with nerve injury. BDNF expression was increased in male, but not female, MSSI-stressed mice at 3 weeks of age. However, MSSI stress did not impact BDNF expression in male or female mice at 12 weeks of age. Our findings suggest that exposure to early life stress exacerbates emotional dysfunction induced by neuropathic pain in a sex-dependent manner. Changes in BDNF expression after early life stress may be associated with neuropathic pain-induced depression-like behavior in adulthood. Furthermore, sex differences in BDNF expression after exposure to early life stress may contribute to sex-specific susceptibility to neuropathic pain-induced emotional dysfunction.

Depression and ischemic heart disease (IHD) are strongly related common disorders. Depression itself is an independent cardiac risk factor and is associated with a two- to threefold increase in IHD mortality. Attention has now shifted to identifying the common underlying mechanisms that could make individuals susceptible to both disorders. Abnormalities that have been implicated in this relationship include abnormal platelet activation, decreased baroreceptor sensitivity and endothelial dysfunction. Depression and IHD both have a high association with environmental stress, and depression is characterized by abnormalities of the stress-hormone axis. This review provides a brief overview of some recent developments in our understanding of the pathophysiological links between stress, depression and IHD.

Depression may be a precursor to substance use disorder in some youngsters, and substance abuse might complicate the subsequent course of depression. This study examined whether hypothalamic-pituitary-adrenal (HPA) activity and stressful life experiences are related to the development of substance use disorder in depressed and nondepressed adolescents, and whether substance use disorder predicts a worsening course of depression. Urinary-free cortisol was measured for 3 nights in 151 adolescents with no prior history of substance use disorder (55 depressed, 48 at high risk for depression, and 48 normal subjects). Information was obtained on recent stressful life experiences. The participants were followed for up to 5 years to assess the onset of substance use disorder, course of depression, and stressful experiences. The relationships among depression, cortisol as a measure of HPA activity, stressful experiences, and substance use disorder were examined. Elevated cortisol was associated with onset of substance use disorder. Stressful life experiences moderated this relationship. Cortisol and stress accounted for the effects of a history or risk of depression on the development of substance use disorder. Substance use disorder was associated with higher frequency of subsequent depressive episodes. Higher cortisol prior to the onset of substance use disorder may indicate vulnerability to substance use disorder. Stressful experiences increase the risk for substance use disorder in such vulnerable youth. The high prevalence of substance use disorders in depressed individuals may be explained, in part, by high levels of stress and increased HPA activity.
Conclusion: By considering the influence of life stress it could be demonstrated that depression and burnout are not identical although they share substantial phenotypic variance (r = .46–.61. Most important, the trivariate associations are the same in a representative employee sample and in an inpatient clinical sample suggesting the same underlying mechanisms covering the whole range from normal behavior to psychopathology. However, only longitudinal data can show if burnout necessarily turns into depression with the consequence that the burnout – life stress association approaches the depression – life stress association over time.

The purpose of this paper was to evaluate relationships between sociodemographic, pregnancy, obstetric, and postnatal variables and postpartum depression, anxiety and stress levels in new mothers. One-hundred-thirty-nine women completed the baseline questionnaire and 105 completed the follow-up questionnaire at 4-6 months postpartum. Sociodemographic and pregnancy factors were assessed at baseline, birth and postnatal factors were assessed at time 2, and depression, anxiety, and stress were assessed at both time points. Caesarean delivery was associated with high postpartum depression, anxiety, and stress levels. Child sleep problems was related to depression, child health problems were related to anxiety, more SLE related to high stress, and maternal sleep problems were related to PPD. However, the results became non-significant after controlling for antenatal distress levels. Finally, women who underwent caesarean delivery had higher antenatal stress, anxiety, and depression levels, relative to women who did not undergo the procedure. Psychological stress and distress tended to persist in the women from the third-trimester of pregnancy to 4-6 months postpartum. It tended to occur in the context of caesarean delivery, maternal sleep problems, child's health and sleep problems, and stressful life-events. Copyright © 2015 Elsevier B.V. All rights reserved.

Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease. The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus. The psychometric evaluation using the Depression Anxiety Stress Scale (DASS)-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus) and group 2 (Control). DASS-42 questionnaire consists of 42 symptoms divided into three subscales of 14 items: Depression scale, anxiety scale, and stress scale. The Student t test was used to determine statistical difference for both the groups and to evaluate for significant relationships among variables. Psychological assessment using DASS-42 reveals lichen planus patients showed higher frequency of psychiatric co morbidities like depression, anxiety and stress compared to control group. This study has provided evidence that the DASS-42 questionnaire is internally consistent and valid measures of depression, anxiety, and stress. Psychiatric evaluation can be considered for patients with oral lichen planus with routine treatment protocols are recommended. DASS-42 Questionnaire can also be used to determine the level of anxiety, stress and depression in diseases of the oral mucosa like recurrent apthous stomatitis, burning mouth syndrome and TMD disorders.
Full Text Available Context: Lichen planus is a psychosomatic disease. Higher frequency of psychiatric symptoms, poor quality of life, higher level of anxiety and neuroendocrine and immune dysregulations, all these factors, will enhance the exacerbation of the disease. Aims: The present study was to assess depression, anxiety and stress levels in patients with oral lichen planus. Methods: The psychometric evaluation using the Depression Anxiety Stress Scale (DASS-42 questionnaire was carried out, by the same investigator on all members of group 1 (Oral Lichen Planus and group 2 (Control.

Predictors of depressive symptoms may differ before and after the first onset of major depression due to stress sensitization. Dependent stressors, or those to which characteristics of individuals contribute, have been shown to predict depressive symptoms in youth. The current study sought to clarify how stressors' roles may differ before and after the first depressive episode. Adolescents (N = 382, aged 11 to 15 at baseline) were assessed at baseline and every 3 months over the course of 2 years with measures of stressors and depressive symptoms. Semi-structured interviews were conducted every 6 months to assess for clinically significant depressive episodes. Hierarchical linear modeling showed a significant interaction between history of depression and idiographic fluctuations in dependent stressors to predict prospective elevations of symptoms, such that dependent stressors were more predictive of depressive symptoms after onset of disorder. Independent stressors predicted symptoms, but the strength of the association did not vary by depression history. These results suggest a synthesis of dependent stress and stress sensitization processes that might maintain inter-episode depressive symptoms among youth with a history of clinical depression.

The current policy guidelines on mental health aim to keep the mentally ill within the community, with the development of social support, including families, hence the emergence of the role of the family caregiver. To identify socio-demographic variables influencing anxiety, depression and stress for the informal caregivers of the mentally ill; to determine the influence of family background variables on caregiver anxiety, depression and stress; to analyse the relationship between social support and caregiver overload with caregiver anxiety, depression and stress. Cross-sectional, descriptive and correlational study with 104 caregivers, mostly female (62.5%), aged between 22 and 77 years with a mean age of 52.03 years. The following were used as instruments: the Family Apgar Scale; the Satisfaction with Social Support Scale (ESSS); the Caregiver Overload Scale (ESC); the Anxiety, Depression and Stress Scales (EADS-21). We found that females have higher rates (Panxiety, depression and stress; participants with less education have more anxiety than those with higher and secondary education (P=.001); caregivers living in rural areas have higher levels of depression (P=.044) and stress (P=.041); those who perceive belonging to families with marked dysfunctions have higher levels of depression (P=.0.001) and stress (P=.000); the higher the overload, the higher the levels of anxiety (P=.002), depression and stress (P=.000).

The direct and interactive effects of neuroticism and stressful life events (chronic and episodic stressors) on the severity and temporal course of depression symptoms were examined in 826 outpatients with mood and anxiety disorders, assessed on three occasions over a one-year period (intake, 6- and 12-month follow-ups). Neuroticism, chronic stress, and episodic stress were uniquely associated with intake depression symptom severity. A significant interaction effect indicated that the strength of the effect of neuroticism on initial depression severity increased as chronic stress increased. Although neuroticism did not have a significant direct effect on the temporal course of depression symptoms, chronic stress significantly moderated this relationship such that neuroticism had an increasingly deleterious effect on depression symptom improvement as the level of chronic stress over follow-up increased. In addition, chronic stress over follow-up (but not episodic stress) was uniquely predictive of less depression symptom improvement. Consistent with a stress generation framework, however, initial depression symptom severity was positively associated with chronic stress during follow-up. The results are discussed in regard to diathesis-stress conceptual models of emotional disorders and the various roles of stressful life events in the onset, severity, and maintenance of depressive psychopathology.

Admission to a professional program marks the beginning of fulfilling a career goal. However, the rigors of professional education can be demanding. Stress, depression, and anxiety (SDA) can interfere with learning, affect academic performance, and impair clinical practice performance. Studies report a general increase in the severity of and extent of mental health problems among college/university students. The literature regarding nursing students' mental health distress identifies academic and personal sources of stress and coping efforts, with emphasis on the stress and anxiety associated with clinical practice. This cross-sectional descriptive exploratory study investigated levels of SDA among nursing students in 3 years of a university-based program. The association between quality of life indicators including known stressors, such as financial concerns and balance between school and personal life, and SDA was also investigated. Through an online survey, 437 participants from one mid-western Canadian undergraduate nursing program completed the Depression Anxiety Stress Scales and provided data on quality of life indicators and demographic information. Participants also were invited to provide narrative data about their experiences with SDA. This article will present significant findings including: levels of SDA; comparisons between our sample and a normative sample on the dimensions of SDA; and the results of multiple regression analysis identifying significant predictors of each dimension. Themes from the qualitative comments from 251 of the participants were identified and added depth and clarity to the quantitative findings. The predominant themes represented were: perceptions of clinical practice, coping, personal issues, and balancing school, work, and personal life. Implications and recommendations for curriculum design, ensuring students understand program expectations prior to admission, and enhancing accessibility to mental health/support services

This prospective study tested the self-complexity buffering hypothesis that greater self-complexity moderates the adverse impact of stress on depression and illness. This hypothesis follows from a model that assumes self-knowledge is represented in terms of multiple self-aspects. As defined in this model, greater self-complexity involves representing the self in terms of a greater number of cognitive self-aspects and maintaining greater distinctions among self-aspects. Subjects completed measures of stressful events, self-complexity, depression, and illness in two sessions separated by 2 weeks. A multiple regression analysis used depression and illness at Time 2 as outcomes, stressful life events and self-complexity at Time 1 as predictors, and depression and illness at Time 1 as control variables. The Stress X Self-Complexity interaction provided strong support for the buffering hypothesis. Subjects higher in self-complexity were less prone to depression, perceived stress, physical symptoms, and occurrence of the flu and other illnesses following high levels of stressful events. These results suggest that vulnerability to stress-related depression and illness is due, in part, to differences in cognitive representations of the self.

Stressful life events are associated with an increase in depressive symptoms and the onset of major depression. Importantly, research has shown that the role of stress changes over the course of depression. The present study extends the current literature by examining the effects of early life stress on emotional reactivity to current stressors. In a multiwave study (N = 281, mean age = 18.76; 68% female), we investigated the proximal changes that occur in depressive symptoms when individuals are faced with life stress and whether a history of childhood emotional abuse moderates this relationship. Results support the stress sensitivity hypothesis for early emotional abuse history. Individuals with greater childhood emotional abuse severity experienced greater increases in depressive symptoms when confronted with current dependent stressors, controlling for childhood physical and sexual abuse. This study highlights the importance of emotional abuse as an indicator for reactivity to stressful life events. © 2013 Wiley Periodicals, Inc.

Previous studies have identified the significant role of stressful life events in the onset of depressive episodes. However, there is a paucity of cross-national studies on stressful life events that precede depression. We aimed to compare types of stressful life events associated with the onset of depressive episodes in patients with major depressive disorder (MDD) in five Asian countries. A total of 507 outpatients with MDD were recruited in China (n = 114), South Korea (n = 101), Malaysia (n = 90), Thailand (n = 103) and Taiwan (n = 99). All patients were assessed with the Mini-International Neuropsychiatric Interview and the List of Threatening Experiences. The prevalence of each type of stressful life events was calculated and compared between each country. The type of stressful life event that preceded the onset of a depressive episode differed between patients in China and Taiwan and those in South Korea, Malaysia and Thailand. Patients in China and Taiwan were less likely to report interpersonal relationship problems and occupational/financial problems than patients in South Korea, Malaysia and Thailand. Understanding the nature and basis of culturally determined susceptibilities to specific stressful life events is critical for establishing a policy of depression prevention and providing effective counseling services for depressed patients. © The Author(s) 2015.

The transition from adolescence to adulthood is associated with stressful adaptation experiences that may increase symptoms of depression. We explored the prevalence and sex differences of depressive symptoms and suicidal ideation in freshmen Latino college students in Puerto Rico, and identified stressful life events that could contribute to symptoms of depression. Two thousand one hundred sixty-three freshmen college students from the University of Puerto Rico (UPR) public education system were assessed for depression symptoms using the Beck Depression Inventory (BDI) and stressful life events using open questions. Nine percent of the sample reported depression symptoms at a moderate or severe level (BDI>20). Chi square analyses revealed a significantly higher prevalence for three of the stressful life events in females than males: relocation (10.2% females vs. 7.3% males; X(2) (1)=4.13, p=.042), break-up of a significant relationship (25.3% females vs. 17.8% males; X(2) (1)=13.76, pstressful life events are associated with an increased prevalence of depression symptoms. Early detection of depression and tailored prevention programs should be developed to improve both mental health and academic performance among the college population. Published by Elsevier B.V.
Full Text Available Compared to the general population, transpersons are exposed to higher levels of discrimination and violence. The stigmatization of transpersons can lead to physical and psychological problems. In particular, transindividuals exhibit a higher prevalence of depression compared to the cispopulation. The gender minority stress model (GMSM provides a comprehensive theoretical basis to interpret these biopsychosocial interactions. Using the GMSM, this study aimed to identify associations between experience of stigmatization and the mental health of transitioned transpersons using correlational analyses and multiple regression models. In total, 143 transpersons were recruited. Multivariate analyses identified three variables (i.e., unemployment, nonaffirmation of gender identity, and internalized transphobia to explain variance of depressive symptoms. Furthermore, a mediation of the proximal factors between distal factors and depressive symptoms was found. However, the moderating effect of resilience factors was not demonstrated. The results confirmed the importance of distal and proximal minority stressors for the mental health of transpersons. At the same time, the protective influence of resilience factors seemed to be surprisingly minor. In the treatment of transpersons, practitioners should not only focus on somatic aspects, but also consider the person’s previous experiences of stigmatization.

Sleep problems are common across the adult life span and may exacerbate depressive symptoms and the effect of common risk factors for depressive symptoms such as life stress. We examine sleep disturbance as a moderator of the association between stressful life events and depressive symptoms across five waves (25 years) of the nationally representative, longitudinal American Changing Lives Study. The sample includes 3,597 adults aged 25 years or older who were surveyed up to five times over 25 years. Multilevel models were run to examine between- and within-person variability in sleep disturbance and life event stress as predictors of depressive symptoms, and an interaction to test sleep disturbance as a moderator is included in a second step. Life events and sleep disturbance were associated with elevated depressive symptoms at the between- and within-person levels. A significant sleep disturbance by interaction of life events was found, indicating that when individuals experienced an above average number of life events and slept more restlessly than usual, they had a higher risk for depressive symptoms than individuals who experienced above average stress but slept well. Sleeping restfully may allow individuals the rejuvenation needed to manage stress adaptively and reduce depressive symptom burden. © The Author 2015.

The present study examined whether such stress generation effects are greater than the effects of stressful life events on depression, and whether stress generation is also evident with anxiety. Participants were two large age cohorts (N = 732 aged 44 years; N = 705 aged 63 years) from the West of Scotland Twenty-07 study. Stressful life events, depression, and anxiety symptoms were measured twice five years apart. Cross-lagged panel analysis examined the mutual influences of stressful life events on depression and on anxiety over time. Life events predicted later depressive symptomatology (p = .01), but the depression predicting life events relationship was less strong (p = .06), whereas earlier anxiety predicted life events five years later (p = .001). There was evidence of sex differences in the extent to which life events predicted later anxiety. This study provides evidence of stress causation for depression and weaker evidence for stress generation. In contrast, there was strong evidence of stress generation for anxiety but weaker evidence for stress causation, and that differed for men and women.

This study examined the association between perceived family economic stress, quality of father-son relationships, and depressive symptoms among African American adolescent fathers. Data were collected during pregnancy from 65 African American adolescents who were first-time fathers, ages 14-19. Results from multiple regression analyses indicated that higher paternal relationship satisfaction was associated with fewer depressive symptoms among adolescent fathers. Additionally, depressive symptoms were higher among adolescent fathers who reported experiencing higher levels of conflict with their fathers. Further, paternal conflict moderated the effect of perceived family economic stress on depressive symptoms. That is, among adolescent fathers experiencing low levels of conflict with their fathers, high perceived family economic stress was associated with more depressive symptoms. Study findings suggest that the risk for depressive symptoms is highest among adolescent fathers experiencing low family economic stress and highly conflictual relations with their fathers. These results highlight the complexities of paternal relationships and perceived economic stressors on depressive symptoms during pregnancy for African American adolescent fathers. The importance of expanding research on influential familial relationships and economic stressors on adolescent African American fathers is discussed. PMID:26617454

Oxidative stress is implicated in both depression and anxiety, but it is currently unclear whether this relates to syndromal diagnoses or trans-diagnostic dimensional symptoms. We examined the relationship between oxidative stress and severity of depression and anxiety symptoms in individuals with Major Depressive Disorder (MDD). Plasma oxidative stress markers F2-isoprostanes and oxidized glutathione (GSSG), and the antioxidant reduced glutathione (GSH), were assessed in 69 physically healthy, medication-free MDD subjects. Symptoms of anxiety and depression were assessed using the Hamilton Anxiety (HAM-A) and Hamilton Depression (HAM-D) Rating Scales. Total HAM-A and HAM-D scores, along with "core" anxiety and depression subscales, and individual HAM-D items "psychic anxiety" and "depressed mood," were related to oxidative stress markers. Analyses controlled for age, sex, BMI, and smoking. Total HAM-A ratings were positively associated with F2-isoprostanes (β=.26, p=.042) and GSSG (β=.25, p=.049), but not GSH (β=.05, p=.711). Core anxiety severity was positively associated with F2-isoprostanes (β=.34, p=.012) and GSSG, although this did not reach significance (β=.24, p=.074). None of the biological markers were significantly associated with total HAM-D or core depression ratings (all p>.13). Subjects scoring high on "psychic anxiety" had elevated F2-isoprostanes (p=.030) and GSSG (p=.020). This was not seen with "depressed mood" scores (all p>.12). We assessed peripheral oxidative markers, but their relationship to the brain is unclear. Oxidative stress is more closely related to anxiety than depression symptoms in MDD. This highlights the importance of relating oxidative stress to specific symptoms and could provide new insights into the biological correlates of affective disorders. Copyright © 2017 Elsevier B.V.

In the evolving work environment of global competition, the associations between work and home stress and psychological well-being are not well understood. To examine the impact of psychosocial stress at work and at home on anxiety and depression. In medically healthy employed men and women (aged 30-60), serial regression analyses were used to determine the independent association of psychosocial stress at work and at home with depression symptoms, measured using the Beck Depression Inventory-II (BDI-II), and anxiety symptoms, measured using the Spielberger Trait Anxiety Inventory (STAI). Psychosocial stress at work was measured using the Job Content Questionnaire to assess job psychological demands, job control, job social support and job insecurity. Psychosocial stress at home was assessed by 12 questions including stress at home, personal problems, family demands and feelings about home life. Serial regression analyses in 129 subjects revealed that job insecurity and home stress were most strongly associated with depression and anxiety symptoms. Job insecurity accounted for 9% of the variation both in BDI-II scores and in STAI scores. Home stress accounted for 13 and 17% of the variation in BDI-II scores and STAI scores, respectively. In addition, job social support was significantly and independently associated with STAI scores but not BDI-II scores. Work and home stress were associated with anxiety and depression symptoms in both men and women. Both work and home stress should be considered in studies evaluating anxiety and depression in working populations. © The Author 2015.

Full Text Available After trauma, depressive disorders are among the most frequent emerging diagnoses. However, although the symptoms of depression are well characterized, the molecular mechanisms underlying this disorder are largely unknown. Factors involved in the heterogeneous pathogenesis of depression include polymorphisms in stress-related genes, gender, age, developmental history, and environmental (traumatic stressors such as epigenetic factors. These factors may make different parts of the stress-related brain systems more vulnerable to different stressful or traumatic life events or psychological stresses, causing alterations in a network of neurotransmitters and neuromodulators including amines, amino acids, nitric oxide (NO, and neuropeptides, and finally make individuals at risk for depression. The hypothalamo–pituitary–adrenal (HPA axis has a prominent position in this network. With the postmortem brain material obtained from the Netherlands Brain Bank, we have carried on a series of studies with the aim to elucidate the specific changes in these systems in relation to special subtypes of depression. Our final destination is to set up tailor-made treatment for depressive patients on the basis of his/her developmental history, genetic and epigenetic background, and the vulnerability in particular neurobiological systems. This presentation is a review of our findings of changes in systems of sex steroids, receptors in the hypothalamic paraventricular nucleus, corticotrophin-releasing hormone, orexin, γ-aminobutyric acid, and NO in the etiology of depression, in relation to HPA activity, sex differences, and suicide.

Prevalence of anxiety, depression and post traumatic stress disorder is high after earthquake. The aim of the study is to study the prevalence and comorbidity of commonly occurring psychological symptoms in people exposed to Nepal mega earthquake in 2015 after a year of the event. A community based, cross sectional, descriptive study was carried out in Bhumlichaur area of Gorkha district, Nepal after around 14 months of the first major earthquake. We used self-reporting questionnaire 20, Post-traumatic stress disorder 8 and hospital anxiety and depression scale to screen for presence of symptoms of anxiety and depression or post-traumatic stress disorder in this population. The risk of having these disorders according to different socio-demographic variable was assessed by calculating odds ratio. All calculations were done using predictive and analytical software (PASW) version 16.0. A total of 198 participants were included in the final data analysis. The mean age of study participants was 35.13 years (SD=18.04). Borderline anxiety symptoms were found in 104 (52.5%) while significant anxiety symptoms were found in 40 (20%) of respondents. Borderline depressive symptoms were seen in 40 (20%) while significant depressive symptoms were seen in 16 (8%) of subjects. Around 27% (n= 53) of respondents were classified as having post-traumatic stress disorder. The prevalence of anxiety and depressive symptoms and post-traumatic stress disorder seems to be high even after one year in people exposed to earthquake.

This review aims to shed light on the relationship that involves exposure to early life stress, depression and Parkinson's disease (PD). A systematic literature search was conducted in Pubmed, MEDLINE, EBSCOHost and Google Scholar and relevant data were submitted to a meta-analysis . Early life stress may contribute to the development of depression and patients with depression are at risk of developing PD later in life. Depression is a common non-motor symptom preceding motor symptoms in PD. Stimulation of regions contiguous to the substantia nigra as well as dopamine (DA) agonists have been shown to be able to attenuate depression. Therefore, since PD causes depletion of dopaminergic neurons in the substantia nigra, depression, rather than being just a simple mood disorder, may be part of the pathophysiological process that leads to PD. It is plausible that the mesocortical and mesolimbic dopaminergic pathways that mediate mood, emotion, and/or cognitive function may also play a key role in depression associated with PD. Here, we propose that a medication designed to address a deficiency in serotonin is more likely to influence motor symptoms of PD associated with depression. This review highlights the effects of an antidepressant, Fluvoxamine maleate, in an animal model that combines depressive-like symptoms and Parkinsonism.

Full Text Available Depression is associated with an unusually high rate of aging-related illnesses and early mortality. One aspect of "accelerated aging" in depression may be shortened leukocyte telomeres. When telomeres critically shorten, as often occurs with repeated mitoses or in response to oxidation and inflammation, cells may die. Indeed, leukocyte telomere shortening predicts early mortality and medical illnesses in non-depressed populations. We sought to determine if leukocyte telomeres are shortened in Major Depressive Disorder (MDD, whether this is a function of lifetime depression exposure and whether this is related to putative mediators, oxidation and inflammation.Leukocyte telomere length was compared between 18 unmedicated MDD subjects and 17 controls and was correlated with lifetime depression chronicity and peripheral markers of oxidation (F2-isoprostane/Vitamin C ratio and inflammation (IL-6. Analyses were controlled for age and sex.The depressed group, as a whole, did not differ from the controls in telomere length. However, telomere length was significantly inversely correlated with lifetime depression exposure, even after controlling for age (p<0.05. Average telomere length in the depressed subjects who were above the median of lifetime depression exposure (≥9.2 years' cumulative duration was 281 base pairs shorter than that in controls (p<0.05, corresponding to approximately seven years of "accelerated cell aging." Telomere length was inversely correlated with oxidative stress in the depressed subjects (p<0.01 and in the controls (p<0.05 and with inflammation in the depressed subjects (p<0.05.These preliminary data indicate that accelerated aging at the level of leukocyte telomeres is proportional to lifetime exposure to MDD. This might be related to cumulative exposure to oxidative stress and inflammation in MDD. This suggest that telomere shortening does not antedate depression and is not an intrinsic feature. Rather, telomere shortening

Purpose To apply a diathesis × stress model to testing the association between peer victimization and depression in a sample of preadolescent girls. Methods DSM-IV symptoms of depression symptoms were measured at ages 9 and 11, assertiveness and peer victimization were assessed by youth report at age 9. Results The interaction of low levels of assertiveness and high peer victimization at age 9 was predictive of depression symptoms at age 11, controlling for earlier depression symptoms. Conclusions The results extend the literature on peer relations and depression by identifying a group of girls who may be particularly vulnerable to the stress of negative peer interactions.

The occurrence of depression in younger adults is related to the combination of long-standing factors such as personality traits (neuroticism) and more acute factors such as the subjective impact of stressful life events. Whether an increase in physical illnesses changes these associations in old age depression remains a matter of debate. We compared 79 outpatients with major depression and 102 never-depressed controls; subjects included both young (mean age: 35 years) and older (mean age: 70 years) adults. Assessments included the Social Readjustment Rating Scale, NEO Personality Inventory and Cumulative Illness Rating Scale. Logistic regression models analyzed the association between depression and subjective impact of stressful life events while controlling for neuroticism and physical illness. Patients and controls experienced the same number of stressful life events in the past 12 months. However, in contrast to the controls, patients associated the events with a subjective negative emotional impact. Negative stress impact and levels of neuroticism, but not physical illness, significantly predicted depression in young age. In old age, negative stress impact was weakly associated with depression. In this age group, depressive illness was also determined by physical illness burden and neuroticism. Our data suggest that the subjective impact of life stressors, although rated as of the same magnitude, plays a less important role in accounting for depression in older age compared to young age. They also indicate an increasing weight of physical illness burden in the prediction of depression occurrence in old age. © 2013 The Authors. Psychogeriatrics © 2013 Japanese Psychogeriatric Society.

Chronic stress is a risk factor for major depression. Social defeat stress is a well-validated murine model of depression. However, little is known about the gene activity dynamics during the development of a depression-like state. We analyzed the effects of social defeat stress of varying duration (10 and 30 days) on the behavioral patterns and prefrontal-cortex transcriptome of C57BL/6 mice. The 10-day exposure to social defeat stress resulted in a high level of social avoidance with no signs of depression-associated behavior. Most animals exposed to 30 days of social defeat stress demonstrated clear hallmarks of depression, including a higher level of social avoidance, increased immobility in the forced swimming test, and anhedonic behavior. The monitoring of transcriptome changes revealed widespread alterations in gene expression on the 10th day. Surprisingly, the expression of only a few genes were affected by the 30th day of stress, apparently due to a reversal of the majority of the early stress-induced changes to the original basal state. Moreover, we have found that glucocorticoid-sensitive genes are clearly stimulated targets on the 10th day of stress, but these genes stop responding to the elevated corticosterone level by the 30th day of stress. The majority of genes altered by the 30-day stress were downregulated, with the most relevant ones participating in chromatin modifications and neuroplasticity (e.g., guanine nucleotide exchange factors of the Rho-family of GTPases). Very different molecular responses occur during short-term and long-term social stress in mice. The early-stress response is associated with social avoidance and with upregulation and downregulation of many genes, including those related to signal transduction and cell adhesion pathways. Downregulation of a few genes, in particular, genes for histone-modifying methyltransferases, is a signature response to prolonged stress that induces symptoms of depression. Altogether, our data

Antenatal maternal mental health problems have numerous consequences for the well-being of both mother and child. This study aimed to test and construct a pertinent model of antenatal depressive symptoms within the conceptual framework of a stress process model. This study utilized a cross-sectional study design. participants were adult women (18 years or older) having a healthy pregnancy, in their third trimester (the mean weeks gestation was 34.71). depressive and anxiety symptoms were measured by Zung's Self-rating Depressive and Anxiety Scale, stress was measured by Pregnancy-related Pressure Scale, social support and coping strategies were measured by Social Support Rating Scale and Simplified Coping Style Questionnaire, respectively. path analysis was applied to examine the hypothesized causal paths between study variables. A total of 292 subjects were enrolled. The final testing model showed good fit, with normed χ (2) = 32.317, p = 0.061, CFI = 0.961, TLI = 0.917, IFI = 0.964, NFI = 0.900, RMSEA = 0.042. This path model supported the proposed model within the theoretical framework of the stress process model. Pregnancy-related stress, financial strain and active coping have both direct and indirect effects on depressive symptoms. Psychological preparedness for delivery, social support and anxiety levels have direct effects on antenatal depressive symptoms. Good preparedness for delivery could reduce depressive symptoms, while higher levels of anxiety could significantly increase depressive symptoms. Additionally, there were indirect effects of miscarriage history, irregular menstruation, partner relationship and passive coping with depressive symptoms. The empirical support from this study has enriched theories on the determinants of depressive symptoms among Chinese primipara, and could facilitate the formulation of appropriate interventions for reducing antenatal depressive symptoms, and enhancing the mental health of

This study aimed to investigate the influences of pubertal timing and stressful life events on Chinese adolescents' depression and delinquency. Sex differences in these influences were also examined. A large sample with 4,228 participants aged 12-15 years (53% girls) was recruited in Beijing, China. Participants' pubertal development, stressful life events, depressive symptoms, and delinquency were measured using self-reported questionnaires. Both early maturing girls and boys displayed more delinquency than their same-sex on-time and late maturing peers. Early maturing girls displayed more depressive symptoms than on-time and late maturing girls, but boys in the three maturation groups showed similar levels of depressive symptoms. The interactive effects between early pubertal timing and stressful life events were significant in predicting depression and delinquency, particularly for girls. Early pubertal maturation is an important risk factor for Chinese adolescents' depression and delinquency. Stressful life events intensified the detrimental effects of early pubertal maturation on adolescents' depression and delinquency, particularly for girls. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Stress generation is a process in which individuals contribute to stressful life events. While research has supported an association between current depression and stress generation, it has been noted that individuals with prior depression tend to contribute to stressors even when they are no longer experiencing a depressive episode. The aim of the study is to elucidate the pathways through which prior major depression predicts interpersonal stress generation in women. Specifically, we examined current subsyndromal depressive symptoms and problematic interpersonal behaviours as potential mediators. Fifty-one college women were followed prospectively for 6 weeks. Participants were interviewed to assess current and past depression as well as stressful life events they experienced over the 6-week period. The findings suggest that prior major depression continues to have an impact even after the episode has ended, as the disorder continues to contribute to stress generation through residual depressive symptoms.

The aim of this study was to determine the oxidative stress; serum level of Total Antioxidant Capacity (TAC)and Malondialdehyde (MDA) level and the depression score among the depressed rotational shift workers in Shahid Tondgouyan Refinery in Tehran (Iran). A cross-sectional study was conducted among all the 189 shift workers in Shahid Tondgouyan oil refinery who were eligible to participate in the study. They did not take any antidepressants for two months or any supplements for two weeks prior to the study entry. Written consent was obtained from the participants. 21- Item Beck Depression Inventory was used to measure the depression level. Furthermore, body weight, height and systolic and diastolic blood pressure were collected from all the participants. The levels of Total Antioxidant Capacity (TAC) and Malondialdehyde (MDA) were measured by 8 ml fasting blood sample. MDA was determined by thiobarbituric acid reaction. Serum total antioxidants were measured using the spectrophotometric ABTS. In the ABTS test, 2,2'-azinobis (3-ethylbenzthiazoline-6-acid) (ABTS) is converted into its radical cation (ABTS•+) by addition of sodium persulphate. This blue-green radical cation absorbs light at 734 nm. ABTS•+ is reactive towards most antioxidants. Descriptive statistics, ANOVA, ANCOVA and regression tests and correlation were used to analyze the data using SPSS software version 16. The age of the participants ranged from 21 to 52 years. The mean age of the participants was 30.58 year (±6.97yr). Of all the participants, 28% (n= 53) had no depression symptoms (depression score between 0 and 9), 65.1% (n=123) were categorized as having mild depression (depression score between 10 and 18) and 6.9% (n=13) were categorized as having moderate depression (depression score between 19 and 29). The participants' BMI ranged from 15.9 to 34.3; the mean BMI of the participants was 24.82 kg/m(2) (+ 3.81 kg/m(2)). The mean of the serum TAC level was 2.51 (± 0.56) mg/dl, and the

Chronic stress is a potent risk factor for depression, but the mechanism by which stress causes depression is not fully understood. To investigate the molecular mechanism underlying stress-induced depression, C57BL/6 inbred mice were treated with repeated restraint to induce lasting depressive behavioral changes. Behavioral states of individual animals were evaluated using the forced swim test, which measures psychomotor withdrawals, and the U-field test, which measures sociability. From these behavioral analyses, individual mice that showed depression-like behaviors in both psychomotor withdrawal and sociability tests, and individuals that showed a resiliency to stress-induced depression in both tests were selected. Among the neuropeptides expressed in the amygdala, thyrotropin-releasing hormone (TRH) was identified as being persistently up-regulated in the basolateral amygdala (BLA) in individuals exhibiting severe depressive behaviors in the two behavior tests, but not in individuals displaying a stress resiliency. Activation of TRH receptors by local injection of TRH in the BLA in normal mice produced depressive behaviors, mimicking chronic stress effects, whereas siRNA-mediated suppression of either TRH or TRHR1 in the BLA completely blocked stress-induced depressive symptoms. The TRHR1 agonist, taltirelin, injection in the BLA increased the level of p-ERK, which mimicked the increased p-ERK level in the BLA that was induced by treatment with repeated stress. Stereotaxic injection of U0126, a potent inhibitor of the ERK pathway, within the BLA blocked stress-induced behavioral depression. These results suggest that repeated stress produces lasting depression-like behaviors via the up-regulation of TRH and TRH receptors in the BLA. Copyright © 2015 Elsevier Ltd. All rights reserved.

Recent literature has indicated that exposure to multiple traumatic events in adults is associated with high levels of posttraumatic stress disorder (PTSD), anxiety, and depression. Against the backdrop of stressful life events and childhood abuse and neglect, we investigated the cumulative effect of multiple trauma exposure on PTSD, anxiety, and depression in an adolescent sample. One thousand one hundred forty 10th-grade learners from 9 Cape Town (South Africa) schools completed questionnaires on stressful life experiences; trauma exposure; and symptoms of anxiety, depression, and PTSD. Our population of interest for this study was adolescents between the ages of 14 and 18 years who had been exposed to serious, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, qualifying traumatic events. The final sample size was thus 922. Rates of trauma exposure, PTSD, depression, and anxiety were high. Controlling for sex, stressful life experiences in the past year, and childhood adversity, we found an effect of cumulative trauma exposure effect on PTSD and depression, with an increase in the number of traumas linearly associated with an increase in symptoms of PTSD (F((4,912)) = 7.60, P cumulative effect on anxiety. Our findings indicate that adolescents exposed to multiple traumas are more likely to experience more severe symptoms of PTSD and depression than those who experience a single event, with this effect independent of childhood adversity and everyday stressful life experiences. Exposure to multiple trauma, however, does not seem to be associated with more severe anxiety symptoms.
Full Text Available Recent epidemiological data suggests 13.3% of Hong Kong residents suffered from Common Mental Disorders, most frequently mixed anxiety and depressive disorder. This study examines the weighted prevalence and associated risk factors of depression, anxiety and stress among Hong Kong nurses. A total of 850 nurses were invited to participate in this cross-sectional study. Participants completed the Depression, Anxiety and Stress Scale 21 and multiple logistic regression was used to determine significant relationships between variables. Chronic past-year illness and poor self-perceived mental health were significant correlates of past-week depression, anxiety and stress. It confirmed further positive correlations between depression and divorce, widowhood and separation, job dissatisfaction, disturbance with colleagues, low physical activity levels and sleep problems. Marital status; general medicine; sleep problems, and a lack of leisure significantly correlated with anxiety. Stress was significantly associated with younger age, clinical inexperience, past-year disturbance with colleagues, low physical activity, no leisure and drinking alcohol. Nurses were more depressed, anxious and stressed than the local general population, with over one-third of our respondents classified as subject to these disorders.

Introduction. The present study examined the relationship between metacognition (i.e., "thinking about thinking") and depression. More specifically, the depressive realism hypothesis (Alloy & Abramson, 1979), which posits that depressed people have a more accurate view of reality than nondepressed people, was tested. Methods. Nondepressed, mildly depressed, and moderately depressed individuals predicted their memory performance by making judgements of learning after each studied item. These predictions were then compared with actual performance on a free recall task to assess calibration, an index of metacognitive accuracy. Results and conclusions. Consistent with the depressive realism hypothesis, mild depression was associated with better calibration than nondepression. However, this "sadder but wiser" phenomenon appears to only exist to point, as moderate depression and nondepression showed no calibration differences. Thus, the level-of-depression account of depressive realism is supported.

Full Text Available Sex differences exist in vulnerability, symptoms and treatment of many neuropsychiatric disorders. In this review we discuss both preclinical and clinical research that investigates how sex influences depression endophenotypes at the behavioral, neuroendocrine, and neural levels across the lifespan. Chronic exposure to stress is a risk factor for depression and we discuss how stress during the prenatal, postnatal, and adolescent periods differentially affects males and females depending on the method of stress and metric examined. Given that the integrity of the hippocampus is compromised in depression, we specifically focus on sex differences in how hippocampal plasticity is affected by stress and depression across the lifespan. In addition, we examine how female physiology predisposes depression in adulthood, specifically in postpartum and perimenopausal periods. Finally, we discuss the underrepresentation of women in both preclinical and clinical research and how this limits our understanding of sex differences in vulnerability, presentation, and treatment of depression.

Full Text Available Background: Stress, anxiety, and postpartum depression are the most common problems among women in their childbearing age. Research has shown that aromatherapy administered during labor reduces anxiety in mothers. With regard to the specific biological conditions in postpartum period and the subsequent drop in hormone levels, this study investigated the effect of lavender on prevention of stress, anxiety, and postpartum depression in women. Materials and Methods: In a clinical trial, 140 women admitted to the obstetric and gynecological unit were randomly divided into aromatherapy and non-aromatherapy groups immediately after delivery. Intervention with aromatherapy consisted of inhaling three drops of lavender essential oil every 8 h with for 4 weeks. The control group received routine care after discharge and was followed up by telephone only. After 2 weeks, 1 and 3 months of delivery, women were assessed by the 21-item Depression, Anxiety, and Stress Scale and the Edinburgh stress, anxiety, and depression scale in the two groups. Data analysis was performed by Mann-Whitney, analysis of variance (ANOVA, and post hoc tests. Level of significance was set as 0.05 for all tests. Results: The results showed that the mean stress, anxiety, and depression at time point of 2 weeks (P = 0.012, P < 0.0001, and P = 0.003, respectively and stress, anxiety, and depression scores at time points of 1 month (P < 0.0001 and 3 months after delivery (P < 0.0001 were significantly lower in the study group compared with the control group. Conclusions: Inhaling the scent of lavender for 4 weeks can prevent stress, anxiety, and depression after childbirth.

This study aimed to investigate and compare the executive functions of students with depression, anxiety, and stress symptoms with those functions in healthy ones. This study was a comparative and non-clinical analysis. The study population comprised all students of Shahid Beheshti University, Tehran, Iran. A total of 448 students were recruited using convenience sampling method. They were also screened using the Depression Anxiety Stress Scales (DASS) test comprising 21 items. Of study participants, 30 people were depressed, 27 had anxiety, and 15 suffered from stress. Then, 50 control people were matched with them. Next, both groups were compared using the Stroop test, Wisconsin card sorting, and cognitive ability test. Using MANOVA test, data analysis revealed no significant differences among 4 groups with regard to selective attention and shifting attention. Depressed group reacted rapidly as opposed to the anxiety group with regard to measures of shifting attention and cognitive abilities; it was observed that the memory, inhibition control, planning, and flexibility of the healthy group were better than those of the 3 other groups. The findings of this research raised specific issues in relation to the role of depression, anxiety, and stress in the disruption of the executive functions of sufferers. Selective and shifting attention and cognitive abilities are specifically affected in this regard. Meanwhile, the role of stress in impairing decision making and the major role of anxiety in impairing sustained attention was shown to be considerable.

We examined maternal avoidant coping as a mediator between maternal parenting stress and maternal depressive symptoms during early adolescence. Three years of self-report data were collected from 173 mothers, beginning when mothers' adolescents were in 6th grade and aged 11-13 years. Utilizing longitudinal path analysis, results indicated that avoidant coping at time two mediated the association between parenting stress at time one and depressive symptoms at time three. Additionally, the reverse direction of effects was examined, revealing that the relation between parenting stress and avoidant coping was unidirectional, while the relation between avoidant coping and depressive symptoms was bidirectional. Our results suggest that during early adolescence, mothers who experience more stress in the parenting role are more likely to engage in higher levels of avoidant coping when faced with parenting problems. In turn, a mother's long-term avoidant reactions to parenting problems may predict increases in depressive symptoms. Moreover, our findings of a bidirectional relation between avoidant coping and depressive symptoms suggest that prior levels of depression might serve as a barrier to efficient and effective coping. The present study may inform preventive intervention efforts aimed at decreasing the use of avoidance in response to parenting stressors by increasing adaptive parental coping with stressors, and providing appropriate support and resources for parents.

In the period of gestation, delivery and post-delivery, fear and tension produced in puerperae are likely to evolve into depression as they worry too much about delivery pain. In recent years, it has been noted that stressful events during this period aggravate postpartum depression. To discuss the effect of these childbirth-related stressful events on neuroendocrine functions of patients with postpartum depression, 300 full-term puerperae who had been admitted to the Beijing Obstetrics and Gynecology Hospital, Capital Medical University between October, 2011 and October, 2013 and who had suffered from stressful childbirth-related events were enrolled as a study group. This group was divided into six subgroups, i.e., A, B, C, D, E and F, based on the number of stressful events they had suffered which were labeled by numbers 1 to 6. Additionally, 100 puerperae from the same hospital who had not suffered from childbirth-related stressful events were taken as controls. Relevant clinical indexes, including serum adrenocorticotropic hormone (ACTH), plasma 5-hydroxytryptamine (5-HT), noradrenaline ELISA (NE), dopamine (DA) and cortisol level were measured and compared. It was found that incidence probability of postpartum depression was significantly different between the study group (13.67%, 41/300) and the control group (7%, 7/100). Moreover, the incidence probability of postpartum depression of puerperae suffering from no less than 4 childbirth-related stressful events was higher than those suffering from no more than 3, and the difference was statistically significant (Pdepression.

Stress, anxiety and depression are raised amongst parents of children with a developmental disorder. However, the processes by which stress leads to depression and anxiety are poorly understood. In a cross-sectional survey, levels of parental stress, depression and anxiety were compared between parents of children with an autistic disorder, children with Down's syndrome and children with no disorder (N = 619) and the mediational role of locus of control was examined. Anxiety and depression were higher in parents of children with a disorder, and highest in parents of children with autism. Locus of control was more external in parents of children with autism. Locus of control failed to mediate the relationship between stress and both anxiety and depression in parents of children with a disorder. This suggests that help for parents of a child with a disorder may be effective if focused on the sources of stress rather than perceived control over events.

Full Text Available Objectives Previous epidemiological studies about oxidative stress and depression are limited by hospital-based case-control design, single-time measurements of oxidative stress biomarkers, and the small number of study participants. Therefore, in this study, we analyzed the association between biomarker of oxidative stress and depressive symptom scores using repeatedly measured panel data from a community-dwelling elderly population. Methods From 2008 to 2010, a total of 478 elderly participants residing in Seoul, Korea, were evaluated three times. Participants underwent the Korean version of the Short Form Generic Depression Scale (SGDS-K test for screening depression, and urinary malondialdehyde (MDA levels were measured as an oxidative stress biomarker. We used a generalized estimating equation with a compound symmetry covariance structure to estimate the effects of oxidative stress on depressive symptom scores. Results A two-fold increase in urinary MDA concentration was significantly associated with a 33.88% (95% confidence interval [CI], 21.59% to 47.42% increase in total SGDS-K scores. In subgroup analyses by gender, a two-fold increase in urinary MDA concentration was significantly associated with increased SGDS-K scores in both men and women (men: 30.88%; 95% CI, 10.24% to 55.37%; women: 34.77%; 95% CI, 20.09% to 51.25%. In bivariate analysis after an SGDS-K score ≥8 was defined as depression, the third and the fourth urinary MDA quartiles showed a significantly increased odds ratio(OR of depression compared to the lowest urinary MDA quartile (third quartile OR, 6.51; 95% CI, 1.77 to 24.00; fourth quartile OR, 7.11; 95% CI, 1.99 to 25.42. Conclusions Our study suggests a significant association between oxidative stress and depressive symptoms in the elderly population.

Full Text Available Abstract Background Major depression is a widely used diagnostic category but there is increasing dissatisfaction with its performance. The diathesis-stress model is an alternative approach that does not require the (sometimes arbitrary imposition of categories onto the spectrum of depressive morbidity. However, application of this model has not been well explored and its consistency with available epidemiologic data is uncertain. Methods Simulation provides an opportunity to explore these issues. In this study, a simulation model based on an intuitive representation of diathesis-stress interaction was developed. Both diathesis and stress were represented using continuous distributions, without categorization. A diagnostic threshold was then applied to the simulation output to create nominal categories and to explore their consistency with available information. Results An apparently complex epidemiologic pattern emerged from the diathesis-stress interaction when thresholds were applied: incidence was time dependent, recurrence depended on the number of past episodes, baseline symptoms were associated with an increased risk of subsequent episodes and the remission rate declined with increasing episode duration. Conclusions A diathesis-stress conceptualization coupled with application of a threshold-based diagnostic definition may explain several of the apparent complexities of major depression epidemiology. Some of these complexities may be artifacts of the nominal diagnostic approach. These observations should encourage an empirical exploration of whether diathesis-stress interactions provide a more parsimonious framework for understanding depression than current approaches.

Occupational stress (OS) among teachers predispose to depression and anxiety. No study was done to assess these problems among Egyptian teachers. This study aimed to assess the prevalence of OS, depression and anxiety among Egyptian teachers. A cross sectional study was done on 568 Egyptian teachers. The respondents filled a questionnaire on personal data, and the Arabic version of the Occupational Stress Index (OSI), the Arabic validated versions of Taylor manifest anxiety scale and the Beck Depression Inventory (BDI) were used to assess OS, anxiety and depression respectively. The prevalence of OS, anxiety and depression among teachers was (100%, 67.5% and 23.2%) respectively. OS, anxiety and depression scores were significantly higher among teachers with an age more than 40years, female teachers, primary school teachers, those with inadequate salary, higher teaching experience, higher qualifications and higher workload. A significant weak positive correlation was found between OS scores and anxiety and depression scores. This study indicated the need for future researches to address risk factors of OS and mental disorders among Egyptian teachers, and the need of periodical medical evaluation of teachers and medical and psychological support for the identified cases.

University students face not only challenges related with independent living, but also academic challenges. This predisposes them to depression, anxiety and stress, which are fairly common. The aim was to assess the prevalence of depression, anxiety and stress, and identify their correlates among university students. A cross-sectional study was conducted on 506 students between the ages of 18 and 24 years from four public universities in the Klang Valley, Malaysia. Through an anonymous, self administered questionnaire, they were assessed by the Depression Anxiety Stress Scale-21 (DASS-21). Data on socio-demographic, family characteristics and living arrangement were also obtained. Student's t-test and one-way ANOVA were used to explore association between these aspects. Analysis showed among all students, 27.5% had moderate, and 9.7% had severe or extremely severe depression; 34% had moderate, and 29% had severe or extremely severe anxiety; and 18.6% had moderate and 5.1% had severe or extremely severe stress scores based on the DASS-21 inventory. Both depression and anxiety scores were significantly higher among older students (20 and above) and those born in rural areas. Whereas, higher stress scores were significantly higher among older students (20 and above), females, Malays and those whose family had either low or high incomes compared to those with middle incomes. The prevalence of anxiety is much higher than either depression or stress, with some differences in their correlates except for age. These differences need to be further explored for development of better intervention programs and appropriate support services targeting this group. Copyright © 2013 Elsevier B.V.

Full Text Available The current industrialized world and ever advancing technology has changed human life by a significant increase in the level of stress and anxiety. Nurses are among those professionals who experience an overwhelming level of stress, anxiety and depression due to work overload and subsequent burnout. The nature of nursing profession for a vulnerable human character increases the possibility of emotional setbacks. Hence, this study was designed to explore and identify the prevalence of anxiety, stress and depression among the Iranian nurses and investigate how these variables relate to personal characteristics and influence the quality of patient care. Using a correlational descriptive design and random cluster method, 242 nurses who worked at different hospital wards in Tabriz, Iran were assessed for anxiety, stress and depression, while their personal characteristics were identified. Data were collected by using a standard questionnaire for stress, anxiety and depression (DASS-21 and later analyzed by SPSS (ver.17.Results showed that Iranian nurses suffered from a moderate level of anxiety, stress and depression and gender influenced these variable rates (p<0.05. Hospital ward type had a relation with stress level (p<0.05, being interested in nursing had an inverse relation to anxiety, stress and depression (p<0.05, while the education level positively related to depression rate among nurses (p<0.05. Type of work at different shifts influenced stress (p<0.05 and marital status reduced depression among nurses (p<0.05. Prevalence of stress and anxiety among the Iranian nurses were at a significant level with susceptibility to experience psychological disorders and provide lower quality of patient care. Findings of this study can alarm the Iranian authorities in healthcare systems to adopt a new policy and improve the current state of health for nurses and patients.

Full Text Available Agriculture is one of the most dangerous industries in the United States. Farmworkers, including migrant farmworkers, are at risk for work-related injuries. This study explores the association between stress, depression, and occupational injury among migrant farmworkers in Nebraska. Occupational injury was hypothesized to significantly increase the odds of farmworkers being stressed and depressed. Two hundred migrant farmworkers (mean age = 33.5 years, standard deviation (SD = 12.53; 93.0% men, 92.9% of Mexican descent were interviewed. In bivariate analyses, results indicated that stress and depression were positively associated with occupational injury. Two logistic regression models were developed. Occupational injury was a significant factor for depression, but not for stress. Participants who had been injured on the job were over seven times more likely to be depressed. These results highlight the interconnection between the work environment and mental health. More must be done to foster well-being in rural, agricultural communities. Improving occupational health and safety information and training, integrating behavioral health services into primary care settings, and strengthening the protections of the Migrant and Seasonal Agricultural Worker Protection Act may improve conditions for migrant farmworkers in the rural Midwest.

Parents of young children generally report more depressive symptoms than parents of adult children or people without children, mainly because the presence of young children increases exposure to significant stressors (such as stressful life events). However, most studies on the depressogenic role of stressful life events in parents of young children have focussed on mothers. Using data from 1138 families with young children in Norway, we investigated gender differences in the effect of stressful life events after a child's birth on the development of parental depressive symptoms in 3 follow-ups at child's ages 3-6 years. We also explored if gender differences in disposition (personality) may explain any gender differences in the depressogenic effect of life events. Nesting parents within families, we found a female gender bias for both neuroticism and depressive symptoms but no gender difference in the number of life events reported. Importantly, the number of stressful life events predicted the level and course of depressive symptoms similarly for mothers and fathers. Personality traits did not change the association between stressful life events and depressive symptoms in either mothers or fathers. Given the study design, causality cannot be inferred. There was no gender difference in the depressogenic effect of stressful life events in our sample. There was no evidence for a female dispositional sensitivity to the depressogenic effect of stressful life events, either. Stressful life events put both mothers and fathers of young children at risk of depression. Copyright © 2018 The Authors. Published by Elsevier B.V. All rights reserved.

Maintaining health and work ability among older employees is a primary target of national labour and social policies (NLSP) in Europe. Depression makes a significant contribution to early retirement, and chronic work-related stress is associated with elevated risks of depression. We test this latter association among older employees and explore to what extent indicators of distinct NLSP modify the association between work stress and depressive symptoms. We choose six indicators, classified in three categories: (1) investment in active labour market policies, (2) employment protection, (3) level of distributive justice. We use data from three longitudinal ageing studies (SHARE, HRS, ELSA) including 5650 men and women in 13 countries. Information on work stress (effort-reward imbalance, low work control) and depressive symptoms (CES-D, EURO-D) was obtained. Six NLSP indicators were selected from OECD databases. Associations of work stress (2004) with depressive symptoms (2006) and their modification by policy indicators were analysed using logistic multilevel models. Risk of depressive symptoms at follow-up is higher among those experiencing effort-reward imbalance (OR: 1.55 95% CI 1.27-1.89) and low control (OR: 1.46 95% CI 1.19-1.79) at work. Interaction terms indicate a modifying effect of a majority of protective NLSP indicators on the strength of associations of effort - reward imbalance with depressive symptoms. Work stress is associated with elevated risk of prospective depressive symptoms among older employees from 13 European countries. Protective labour and social policies modify the strength of these associations. If further supported findings may have important policy implications.

Full Text Available The study identified the profile of the single working mothers in terms of number of children, number of years as a single parent and reason for being a single parent; assessed the single mothers’ stress level and adversity quotient; determined the significant difference of stress level and adversity quotient of single mothers when grouped according to profile variables; determined the best predictor of stress level and adversity quotient. Moreover this research endeavoured to test significant relationship between the adversity quotient and stress level of single working mothers. Lastly, it proposed a stress management program for single working mothers for them to cope with their stress and adversities in life. The researcher employed quantitative method using standardized questionnaires namely Depression, Anxiety, Stress Scale (DASS and Adversity Response Profile (ARP. The respondents were twenty five (25 single working mothers of the students of Batangas State University. From the results, majority of the respondents have 3 children, widow and in early years as single parent; with a normal level of stress and an average adversity quotient.. There are no significant differences on the stress level and adversity quotient of the respondents when grouped according to profile variables. Finally, stress level has no significant effect on adversity quotient of single working mothers. From the findings, the researcher further recommends that the Office of Guidance and Counseling should update the student information database to determine students with a single working mother. The Parent-Teacher Association may form a single-parent subgroup for the single working mothers to be able to identify to other mothers with same situation. Moreover, the proposed stress management program may be reviewed and implemented by the Office of Guidance and Counseling in coordination with the Parent-Teacher Association of Batangas State University.

Prenatal restraint stress (PRS) can induce persisting changes in individual's development. PRS increases anxiety and depression-like behaviors and induces changes in the hypothalamo-pituitary-adrenal (HPA) axis in adult PRS rats after exposure to stress. Since adaptive capabilities also depend on temporal organization and synchronization with the external environment, we studied the effects of PRS on circadian rhythms, including the sleep-wake cycle, that are parameters altered in depression. Using a restraint stress during gestation, we showed that PRS induced phase advances in hormonal/behavioral circadian rhythms in adult rats, and an increase in the amount of paradoxical sleep, positively correlated to plasma corticosterone levels. Plasma corticosterone levels were also correlated with immobility in the forced swimming test, indicating a depressive-like profile in the PRS rats. We observed comorbidity with anxiety-like profile on PRS rats that was correlated with a reduced release of glutamate in the ventral hippocampus. Pharmacological approaches aimed at modulating glutamate release may represent a novel therapeutic strategy to treat stress-related disorders. Finally, since depressed patients exhibit changes in HPA axis activity and in circadian rhythmicity as well as in the paradoxical sleep regulation, we suggest that PRS could represent an original animal model of depression.

Objective: Anxiety and stress are common in patients undergoing invasive procedures. Coronary angiography is a definitive diagnostic evaluation for coronary artery disease and valvular disease. It is necessary to give information to the patients in order to minimize levels of anxiety and stress to this invasive procedure. The aim of this study was to evaluate the effect of patients education by video on levels of anxiety, stress and depression of patients undergoing coronary angiography. Methodology: In a quasi-experimental, pretest-posttest design, 128 patients were randomly assigned to either control or experimental group. Control group received verbal routine education by nurses and experimental group received an informative video about coronary angiography procedure as well as pre and post angiography interventions. Using Depression, Anxiety, Stress Scale (DASS-21) levels of these variables were measured before and after education. Results: Seventy eight (60.9%) males and fifty (39.1%) females participated in the study. There was a statistically significant reduction in the Anxiety, stress and depression levels of experimental group after video information (P = .000). There was a statistically significant correlation between sex with anxiety (P = .000) and stress (P = .04). Conclusions: The use of patients education by informative video is a useful method for decreasing psychological parameters of patients undergoing coronary angiography procedure. Results of the study confirm the usefulness of video information prior to an Invasive angiography procedure. (author)

Globally, there have been increasing numbers of migrant women; these women are at an increased risk for depressive symptoms. The purpose of this study was to examine the associations among acculturation, acculturative stress and depressive symptoms in Vietnamese women who migrated to South Korea through marriages. We hypothesized that acculturative stress would serve as a mediator in the relationship between acculturation and depressive symptoms. Our findings from surveys with 217 Vietnamese immigrant women showed that the indirect effect of acculturation on depressive symptoms, mediated through acculturative stress [- .15 (.04)], was significant (bias corrected 95% confidence interval for the indirect effect = - .25, - .08). Low levels of acculturation increased acculturative stress, which in turn led to the elevated symptoms of depression. Our findings not only illuminate the adaptation processes of international, female migrants but also suggest avenues to protect and promote their mental well-being.

Overgeneral memory (OGM), the tendency to retrieve categories of events from autobiographical memory instead of single events, is found to be a reliable predictor for future mood disturbances and post-traumatic symptom severity. Patients with borderline personality disorder (BPD) often report co-morbid episodes of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). Therefore, we investigated whether OGM would predict depression severity and (post-traumatic) stress symptoms in BPD patients. At admission (N = 54) and at six-month follow-up (N ≥ 31), BPD patients completed the Structured Clinical Interview for DSM-IV Disorders, the Assessment of DSM-IV Personality Disorders, the Autobiographical Memory Test, the Beck Depression Inventory-2nd edition (BDI-II), and the Impact of Event Scale. OGM at baseline predicted (a) higher levels of depressive symptoms at follow-up and (b) more intrusions related to a stressful event over and above baseline levels of borderline symptoms, depressive symptoms, and intrusions, respectively. No association was found between memory specificity and event-related avoidance at follow-up. Despite previous findings suggesting that OGM in BPD is less robust than in MDD and PTSD, our results suggest that memory specificity in BPD patients may have some relevance for the course of depressive and stress symptomatology in BPD.

Contemporary literature suggests that medical education might adversely affect students' mental health. Alfaisal University in Riyadh, Saudi Arabia is a developing institution; hence, there has been a concern regarding the mental well-being of the students. This study was designed to assess the traits of depression, anxiety, and stress among students in relation to potential underlying reasons. All 575 medical students across the 5 years of study participated by filling out the Depression, Anxiety, and Stress Scale-21 (DASS-21) questionnaire anonymously twice. Firstly, 2-3 weeks before a major examination (pre-examination), and secondly, during regular classes (post-examination). Correlation was sought regarding sex, year of scholarship, attendance of a premedical university preparatory program (UPP), housing, and smoking. Subjective comments from students were also obtained. A total of 76.8% and 74.9% of students participated in pre-and post-examination groups, respectively. The majority were the children of expatriate workers in Saudi Arabia, and included Arabs, South Asians, and North Americans. Prevalence of depression, anxiety, and stress was high (43%, 63%, and 41%, respectively) which reduced (to 30%, 47%, and 30%, respectively) to some extent after examinations. Saudis and those who had attended UPP had higher DASS-21 scores. Smoking and female sex predicted higher levels of "baseline" depression, anxiety, or stress. The students perceived the curriculum and schedule to be the primary causes of their high DASS-21 scores. The students had high "baseline" traits of depression, anxiety, and stress, and these were higher if an examination was near, especially among Saudis and those who had attended UPP. Smoking and female sex predicted higher levels of "baseline" depression, anxiety, or stress. Students suggested that study burden and a busy schedule were the major reasons for their high DASS-21 scores.

Nicotine dependence is common in people with mood disorders; however the operative pathways are not well understood. This paper reviews the contribution of inflammation and oxidative stress pathways to the co-association of depressive disorder and nicotine dependence, including increased levels of pro-inflammatory cytokines, increased acute phase proteins, decreased levels of antioxidants and increased oxidative stress. These could be some of the potential pathophysiological mechanisms involved in neuroprogression. The shared inflammatory and oxidative stress pathways by which smoking may increase the risk for development of depressive disorders are in part mediated by increased levels of pro-inflammatory cytokines, diverse neurotransmitter systems, activation the hypothalamic-pituitary-adrenal (HPA) axis, microglial activation, increased production of oxidative stress and decreased levels of antioxidants. Depressive disorder and nicotine dependence are additionally linked imbalance between neuroprotective and neurodegenerative metabolites in the kynurenine pathway that contribute to neuroprogression. These pathways provide a mechanistic framework for understanding the interaction between nicotine dependence and depressive disorder. Copyright © 2013. Published by Elsevier Ltd.

Identifying the level of anxiety, stress and depression symptoms in family members of patients with heart failure; identifying the relationship between these feelings with sociodemographic and clinical variables. A cross-sectional study carried out with 100 family members. Depression, anxiety, and stress were evaluated by the Beck Depression and Anxiety Inventories and the Perceived Stress Scale - 10. The relationship between feelings and variables was performed through the t-test, Mann-Whitney or Kruskal-Wallis. Mean depression was 8.24, anxiety was 77.95, and stress was 17.43. The correlation coefficient between depression and anxiety and depression and stress was 0.53, and it was 0.66 between anxiety and stress. Females (p=0.002, p=0.031), smoking (p=0.05, p=0.011) and sedentary lifestyle (p=0.023, p=0.001) were related to anxiety and stress, respectively. Family income lower than five minimum wages (p=0.012) was related to depression, and regular/poor self-perceived health status related to the three feelings. Family members did not present high levels of these feelings. The scales were directly correlated with each one another and some variables were related to stress, anxiety and depression.

This study investigated the specific association of stressful life events (SLE) and experiential avoidance (EA) with depression in patients with mental disorders. It also analyzed the possible mediating role of depression in the relation of EA to well-being and life satisfaction. A total of 147 patients (mean age = 40.16 years) diagnosed with anxiety, mood or adjustment disorder were recruited from a mental health centre. They completed measures of SLE, EA, depression, well-being and life satisfaction. Regression analyses showed that SLE and EA were positively related to depression (R 2 = .45), although the contribution made by EA was higher (β = .61, p depression. This indirect effect was less consistently supported with respect to emotional well-being (B = -3.33, SE = .48, p depression in patients with mental disorders. The results also provide evidence that depression seems to play an important mediational role when considering the negative impact that EA exerts on patients´ well-being and satisfaction.

Major life stressors, especially those involving interpersonal stress and social rejection, are among the strongest proximal risk factors for depression. In this review, we propose a biologically plausible, multilevel theory that describes neural, physiologic, molecular, and genomic mechanisms that link experiences of social-environmental stress with internal biological processes that drive depression pathogenesis. Central to this social signal transduction theory of depression is the hypothesis that experiences of social threat and adversity up-regulate components of the immune system involved in inflammation. The key mediators of this response, called proinflammatory cytokines, can in turn elicit profound changes in behavior, which include the initiation of depressive symptoms such as sad mood, anhedonia, fatigue, psychomotor retardation, and social-behavioral withdrawal. This highly conserved biological response to adversity is critical for survival during times of actual physical threat or injury. However, this response can also be activated by modern-day social, symbolic, or imagined threats, leading to an increasingly proinflammatory phenotype that may be a key phenomenon driving depression pathogenesis and recurrence, as well as the overlap of depression with several somatic conditions including asthma, rheumatoid arthritis, chronic pain, metabolic syndrome, cardiovascular disease, obesity, and neurodegeneration. Insights from this theory may thus shed light on several important questions including how depression develops, why it frequently recurs, why it is strongly predicted by early life stress, and why it often co-occurs with symptoms of anxiety and with certain physical disease conditions. This work may also suggest new opportunities for preventing and treating depression by targeting inflammation.

Recent studies have identified high levels of job stress in military personnel. This study examined the relationship among job stress, depression, work performance, types of stressors, and perceptions about supervisors in military personnel. Eight hundred nine military personnel answered a 43-item survey on work stress, physical and emotional health, work performance, perceptions about leadership, job stressors, and demographics. More than one- quarter (27.4%) of this military population reported suffering from significant job stress. Both the report of work stress and depression were significantly related to impaired work performance, more days of missed work, poorer physical health, and negative perceptions about the abilities of supervisors and commanders. Depression and job stress were significantly and positively related to each other. These results support accumulating data indicating that work stress is a significant occupational health hazard in the routine military work environment. Targeting and eliminating sources of job stress should be a priority for the U.S. military to preserve and protect the mental health of military personnel.

Background The biology of peripartum depression remains unclear, with altered stress and the Hypothalamus-Pituitary-Adrenal axis response having been implicated in its pathophysiology. Methods The current study was undertaken as a part of the BASIC project (Biology, Affect, Stress, Imaging, Cognition), a population-based longitudinal study of psychological wellbeing during pregnancy and the postpartum period in Uppsala County, Sweden, in order to assess the association between evening salivary cortisol levels and depressive symptoms in the peripartum period. Three hundred and sixty-five pregnant women from the BASIC cohort were recruited at pregnancy week 18 and instructed to complete a Swedish validated version of the Edinburgh Postnatal Depression Scale at the 36th week of pregnancy as well as the sixth week after delivery. At both times, they were also asked to provide evening salivary samples for cortisol analysis. A comprehensive review of the relevant literature is also provided. Results Women with postpartum EPDS score ≥ 10 had higher salivary evening cortisol at six weeks postpartum compared to healthy controls (median cortisol 1.19 vs 0.89 nmol/L). A logistic regression model showed a positive association between cortisol levels and depressive symptoms postpartum (OR = 4.1; 95% CI 1.7–9.7). This association remained significant even after controlling for history of depression, use of tobacco, partner support, breastfeeding, stressful life events, and sleep problems, as possible confounders (aOR = 4.5; 95% CI 1.5–14.1). Additionally, women with postpartum depressive symptoms had higher postpartum cortisol levels compared to both women with depressive symptoms antenatally and controls (p = 0.019 and p = 0.004, respectively). Conclusions Women with depressive symptoms postpartum had higher postpartum cortisol levels, indicating an altered response of the HPA-axis in postpartum depression. PMID:26322643

Depression is the most common form of mental disability in the world. Depressive episodes may be precipitated by severe acute stressful events or by mild chronic stressors. Studies on the mechanisms of depression require both appropriate experimental models (most of them based on the exposure of animals to chronic stressors), and appropriate tests for assessment of depressive states. In this study male Wistar rats were exposed to two different chronic stress paradigms: an eight-week chronic unpredictable mild stress or a two-week combined chronic stress. The behavioral effects of stress were evaluated using sucrose preference, forced swim and open field tests. After the exposure to chronic unpredictable mild stress, anhedonia was developed, activity in the open field increased, while no changes in the duration of passive floating could be detected. After chronic combined stress, anhedonia was also evident, whereas behavior in the open field and forced swim test did not change. The levels of corticosterone in the blood and brain structures involved in stress-response did not differ from control in both experiments. The absence of significant changes in corticosterone levels and passive floating may be indicative of the adaptation of animals to chronic stress. Anhedonia appears to be a more sensitive indicator of depressive-like behavioral effects of chronic stress as compared to behavior in the forced swim or open field tests.

Depression and burnout are highly prevalent among residents, but little is known about modifiable personality variables, such as resilience and stress from uncertainty, that may predispose to these conditions. Residents are routinely faced with uncertainty when making medical decisions. To determine how stress from uncertainty is related to resilience among pediatric residents and whether these attributes are associated with depression and burnout. We surveyed 86 residents in pediatric residency programs from 4 urban freestanding children's hospitals in North America in 2015. Stress from uncertainty was measured with the use of the Physicians' Reaction to Uncertainty Scale, resilience with the use of the 14-item Resilience Scale, depression with the use of the Harvard National Depression Screening Scale; and burnout with the use of single-item measures of emotional exhaustion and depersonalization from the Maslach Burnout Inventory. Fifty out of 86 residents responded to the survey (58.1%). Higher levels of stress from uncertainty correlated with lower resilience (r = -0.60; P resilience (56.6 ± 10.7 vs 85.4 ± 8.0; P resilience (76.7 ± 14.8 vs 85.0 ± 9.77; P = .02) compared with residents who were not burned out. We found high levels of stress from uncertainty, and low levels of resilience were strongly correlated with depression and burnout. Efforts to enhance tolerance of uncertainty and resilience among residents may provide opportunities to mitigate resident depression and burnout. Copyright © 2018 Academic Pediatric Association.

Abstract Background While it is recognised that depression is prevalent in Rheumatoid Arthritis (RA), recent studies have also highlighted significant levels of anxiety in RA patients. This study compared two commonly used scales, the Depression Anxiety and Stress Scale (DASS) and the Hospital Anxiety and Depression Scale (HADS), in relation to their measurement range and cut points to consider the relative prevalence of both constructs, and if prevalence rates may be due to scale-specific ca...
Three experiments are reported in which expectancies about performance in stressful conditions by nondepressed and depressed nonclinical populations were examined. The first experiment was concerned with estimates of either errors or response rates made in advance, with regard to the likely competence level of a (hypothetical) person allegedly working in conditions of either loud noise, fatigue, sleep loss, social stress, or incentive. Nondepressed subjects as well as depressed subjects provided negative expectancies. The second experiment involved obtaining an estimate of personal competence in conditions where subjects were instructed that personal performance on the task would be required after the estimate had been provided. Nondepressed subjects differed from depressed subjects in that the estimates of the former were less negative in terms of the magnitude of the estimates provided. A third experiment was designed to see whether the negative expectancies about performance in stress exhibited both by nondepressed and by depressed subjects would be used in making allowances for the competence of a typist on the basis of a typescript allegedly produced under high noise conditions. An unexpected effect was that depressed subjects judged the typist more harshly and failed to make allowance for adverse working conditions in the way that nondepressed subjects did. The results are discussed in terms of the implications for understanding cognitive factors in depression.
Full Text Available Background: Cancer diagnosis is the biggest stress for the child and his family. Diagnosis and treatment of cancer in children can cause stress, which often has a negative effect on the health of parents. Psychological reactions such as anxiety, depression, denial and loss of confidence in parents observed that because of the fear of recurrence and future of children. This study aimed to determine the level of stress and anxiety and depression in parents of children with leukemia who were in the maintenance phase of treatment. Methods: This cross-sectional study has been conducted on 48 parents have referred to the clinic of Dr. Sheikh Hospital of Mashhad City, Iran, whom selected using easy sampling method. DASS-21 questionnaire was used for data collection. Another questionnaire containing demographic information such as age, sex, income, educational level and duration of illness was filled under supervision of the psychologist and pediatric physician. Data with SPSS software, ver. 20 (IBM, Armonk, NY, USA, descriptive statistics and Pearson correlation analysis was performed. Results: The results showed that in this study, 37% had abnormal stress levels (33% and 2% of mild stress, moderate stress and severe stress 2% and 79% had abnormal anxiety level (mild 19%, moderate 31% and severe 29% and 67% had abnormal depression level (mild 33%, moderate depression 33% tests, respectively. In our study, there was no relationship between age, sex and duration of illness with these variables. Conclusion: According to this study, in addition to the classic treatment of patients, parent’s mental performance should be paid attention.

Though there is a considerable amount of research supporting the association between stressful life events and major depression, there is a paucity of research concerning a range of other life stress constructs, non-depressive disorders, the role of stable personality traits, and gender differences. This study addresses these deficits by: (a) focusing on the association between interpersonal and non-interpersonal chronic life stress (CLS) and both depressive and anxiety disorders; (b) examining the roles of neuroticism and low extraversion in these associations; and (c) assessing gender differences. Participants were 603 adolescents from a study examining risk factors for emotional disorders. Depression and social phobia were associated with interpersonal CLS (IP-CLS), with neuroticism partially accounting for these associations. Low extraversion partially accounted for the association between social phobia and IP-CLS. Depression was also associated with non-interpersonal CLS (NI-CLS), but only in females. This study provides preliminary evidence for the importance of personality variables in explaining shared associations between stress and depression. Additionally, the stress-social phobia relationship is highlighted with no evidence supporting an association between other anxiety disorders and CLS.

Chronic stress is considered a widely accepted risk factor for the development of neuropsychiatric and neurological disorders. Indeed, high cortisol levels, and, thus, hypothalamic pituitary adrenal (HPA)-axis dysregulation, have been indicated as the most frequent alteration in patients affected by depression, as well as by Alzheimer's disease (AD). Furthermore, depressive state has been pointed as an early manifestation of AD, advocating an overlap between these neuropathological events. We have previously demonstrated that central soluble beta amyloid 1-42 (Aβ) administration peptide induces a depressive like-behavior in rats, with altered HPA axis activation, reduced cortical serotonin and neurotrophin levels. The crucial role of Aβ in stress response is becoming more and more evident, indeed many reports indicate that its release is increased in stressful conditions and stress-based paradigm. Furthermore, it has been reported that stress controls Aβ production and/or clearance. Chronic stress is responsible of inducing neuroinflammation processes and reduced serotoninergic tone, both pathophysiological mechanisms proposed in the association of depression with another chronic disease, such as diabetes. Likewise, AD has also been indicated as type 3 diabetes, considering the large body of literature that suggests common biological bases. Thus, the main aim of the present review is to evaluate the most recent literature findings in humans and animal models in regard to the role of Aβ in stress response and in relation to the biological substrates and pathological pathways common to AD and comorbid diseases, such as depression and diabetes.

The thesis of this review is that oxidative stress is the central factor in major depressive disorder (MDD) and Alzheimer's disease (AD). The major elements involved are inflammatory cytokines, the hypothalamic-pituitary axis, the hypothalamic-pituitary gonadal, and arginine vasopressin systems, which induce glucocorticoid and "oxidopamatergic" cascades when triggered by psychosocial stress, severe life-threatening events, and mental-affective and somatic diseases. In individuals with a genomic vulnerability to depression, these cascades may result in chronic depression-anxiety-stress spectra, resulting in MDD and other known depressive syndromes. In contrast, in subjects with genomic vulnerability to AD, oxidative stress-induced brain damage triggers specific antioxidant defenses, i.e., increased levels of amyloid-β (Aβ) and aggregation of hyper-phosphorylated tau, resulting in paired helical filaments and impaired functions related to the ApoEε4 isoform, leading to complex pathological cascades culminating in AD. Surprisingly, all the AD-associated molecular pathways mentioned in this review have been shown to be similar or analogous to those found in depression, including structural damage, i.e., hippocampal and frontal cortex atrophy. Other interacting molecular signals, i.e., GSK-3β, convergent survival factors (brain-derived neurotrophic factor and heat shock proteins), and transition redox metals are also mentioned to emphasize the vast array of intermediates that could interact via comparable mechanisms in both MDD and AD.

Specifically, alterations in pro-inflammatory cytokines have been related to the development of several psychological and neurobiological manifestations of depressive disorder, as well as to stress exposure. A number of findings point to tumor necrosis factor alpha (TNF-α as one of the central factors in these processes. Accordingly, in the present study, we test the hypothesis that specific influences of chronic stressors related to traumatic stress and dissociation are related to alterations in TNF-α levels. We performed psychometric measurement of depression (Beck Depression Inventory [BDI]-II, traumatic stress symptoms (Trauma Symptom Checklist [TSC]-40, and psychological and somatoform dissociation (Dissociative Experiences Scale [DES] and Somatoform Dissociation Questionnaire [SDQ]-20, respectively, and immunochemical measure of serum TNF-α in 66 inpatients with unipolar depression (mean age 43.1 ± 7.3 years. The results show that TNF-α is significantly related to DES (Spearman R=−0.42, P<0.01, SDQ-20 (Spearman R=−0.38, P<0.01, and TSC-40 (Spearman R=−0.41, P<0.01, but not to BDI-II. Results of the present study suggest that TNF-α levels are related to dissociative symptoms and stress exposure in depressed patients. Keywords: depression, dissociation, TNF-alpha, traumatic stress

To explore compassion fatigue and compassion satisfaction with the potential contributing factors of anxiety, depression and stress. To date, no studies have connected the quality of work-life with other contributing and co-existing factors such as depression, anxiety and stress. A self-report exploratory cross sectional survey of 132 nurses working in a tertiary hospital. The reflective assessment risk profile model provides an excellent framework for examining the relationships between the professional quality of work factors and contributing factors within the established risk profiles. The results show a definite pattern of risk progression for the six factors examined for each risk profile. Additionally, burnout and secondary traumatic stress were significantly related to higher anxiety and depression levels. Higher anxiety levels were correlated with nurses who were younger, worked full-time and without a postgraduate qualification. Twenty percent had elevated levels of compassion fatigue: 7.6% having a very distressed profile. At-risk nurses' stress and depression scores were significantly higher than nurses with higher compassion satisfaction scores. The employed nurse workforce would benefit from a psychosocial capacity building intervention that reduces a nurse's risk profile, thus enhancing retention. © 2013 John Wiley & Sons Ltd.
Full Text Available Background/Aim. Comorbidity of the posttraumatic stress disorder (PTSD and depression is often recognized in the clinical practice. The aim of the paper was to determine the severity of depression and the group of symptoms which are the most prominent in clinical depression comorbid with PTSD. Methods. Totally 60 patients were assessed and divided into the experimental and control group using the Structured Clinical Interview for DSM-IV Axis I Disorders, Investigator Version (SCID-I, modified (SCID for DSM-IV and ICD-10 diagnostic criteria. The presence and the severity of the disorders were assessed by means of the following instruments: Clinician-Administrated PTSD Scale for DSM-IV (CAPS-DX, Montgomery-Asberg Depression Rating Scale (MADRS and 17-item Hamilton Rating Scale for Depression (HAMD. The differences between groups were evaluated using Student t test and by means of the correlation analysis of the data with p < 0.05. Results. The obtained results showed that depression witch was comorbid with PTSD was of significant clinical severity with 31.20 score on HAMD and 30.43 score on MADRS in PTSD-D group. The group of the symptoms: lassitude, inability to feel, suicidal thoughts and inner tension contributed mostly to the global severity of the comorbid clinical depression on MADRS. The group of the symptoms: suicide and somatic symptoms, gastrointestinal, guilt, hypochondriasis, work and activity, anxiety psychic, agitation, and weight loss, genital symptoms and anxiety somatic contributed mostly to the global severity of comorbid clinical depression on HAMD. The average score was 16.03 and 16.97 on HAMD and MADRS, respectively in PTSD group. Conclusion. Depression which is comorbid with posttraumatic stress disorder represents significant clinical entity with domination of the different groups of symptoms between the groups PTSD and PTSD-D on HAMD. Identification of aforementioned severity of illness and delineated group of symptoms lead

Stressful life events and chronic stress are implicated in the development of depressive disorder in humans. Neuropeptide Y (NPY) and galanin have been shown to modulate the stress response, and exert antidepressant-like effects in rodents. To further investigate these neuropeptides in depression......-like behaviour, NPY and galanin gene expression was studied in brains of mice subjected to chronic restraint stress (CRS) and concomitant treatment with the antidepressant fluoxetine (FLX). CRS caused a significant increase in depression-like behaviour that was associated with increased NPY mRNA levels...... in the medial amygdala. Concomitant FLX treatment reverted depression-like effects of CRS and led to significant increases in levels of NPY and galanin mRNA in the dentate gyrus, amygdala, and piriform cortex. These findings suggest that effects on NPY and galanin gene expression could play a role...

To explore the relationship between levels of reported depression, anxiety, and stress with scores on the Conners's Adult ADHD Rating Scale (CAARS). Information was obtained from 84 1st-year psychology students using the CAARS, the Depression Anxiety and Stress Scale (DASS), and the Life Experiences Survey (LES). Approximately 23%, 18%, and 12% of students scored above critical values on the Diagnostic and Statistical Manual of Mental Disorders (4th ed., DSM-IV) Inattention Symptoms, the DSM-IV ADHD Symptoms Total, and the Inattention/Restlessness subscales, respectively. CAARS scores were positively related to reported levels of depression, anxiety, and stress, which accounted for significant variance among the three subscales. Only 5% of participants scored above recommended critical values on the ADHD index; however, a significant amount of the variance on this measure was also attributable to the DASS. Mood symptoms such as depression, anxiety, and stress may obscure correct attribution of cause in those being evaluated for ADHD.

Full Text Available Abstract Background Alzheimer's disease presents a social and public health problem affecting millions of Italians. Those affected receive home care from caregivers, subjected to risk of stress. The present investigation focuses on stress, anxiety and depression in caregivers. Methods Data on 200 caregivers and their patients were collected using a specific form to assess cognitive, behavioural, functional patient (MMSE, and ADL-IAD and caregiver stress (CBI. The relationship between stress, depression and disease has been assessed by means of a linear regression, logistic analysis which reveals the relationship between anxiety, stress and depression and cognitive problems, age, the patient's income. Results The caregivers are usually female (64%, mean age of 56.1 years, daughters (70.5%, pensioners and housewives (30%, who care for the sick at home (79%. Of these, 53% had little time for themselves, 55% observed worsening of health, 56% are tired, 51% are not getting enough sleep. Overall, 55% have problems with the patient's family and/or their own family, 57% at work. Furthermore, 29% feel they are failing to cope with the situation as they wish to move away from home. The increase in the degree of anxiety and depression is directly proportional to the severity of the illness, affecting the patient (r = 0.3 stress and depression r = 0.4 related to CBI score. The memory disorders (OR = 8.4, engine problems (OR = 2.6, perception disorders (OR = 1.9 sick of the patient with Alzheimer's disease are predictive of caregiver stress, depression is associated with the presence of other disorders, mainly behavioural (OR = 5.2, low income (OR = 3.4, patients Conclusion The quality of life of caregivers is correlated with the severity of behavioural disorders and duration of the Alzheimer's disease. The severity of the disease plays an important role in reorganization of the family environment in families caring for patients not institutionalised. It is

To determine the factors related to stress, Burnout and depression in urology, as well as consequences in residents and urologists, in addition to the possible applicable strategies to diminish and treat them. Depression, stress and Burnout syndrome has become a problem in urology specialty. These topics have gained interest in international congresses and urological associations. Efforts are being made to find related factors as well as possible strategies and applicable support programs. Burnout frequency is higher among health professionals than general population, 40-76% in students and residents, its incidence has skyrocketed in recent years, in addition Urology is one of the specialties with highest incidence and severity. Its increase has been related to work overload, documentation, administrative/bureaucratic workload, hostile work environment; its consequences include poor work performance, medical errors, depression, substance abuse, disruption in family and couple relationships and suicidal ideation. Strategies for prevention including resilience training, lifestyle balance, teamwork, and support programs. Stress, burnout and depression are problems in urology, early detection, promoting individual techniques in resilience, lifestyle and teamwork are fundamental now and for the future of the specialty. Developing and implementing support programs should be seriously considered by health systems and urological associations.

Maternal stress during pregnancy has been linked to premorbid abnormalities associated with depression (e.g., difficult temperament, cognitive deficits) in offspring. However, few studies have looked across developmental periods to examine maternal stress during pregnancy and offspring depression during adolescence and whether these associations differ by sex. The current study used data from 1711 mother-offspring dyads (offspring sex: 49.8% male) in a longitudinal birth cohort study. Maternal narratives collected during pregnancy were qualitatively coded for stress-related themes by independent raters. Latent class analysis (LCA) identified distinct subgroups of offspring based on exposure to maternal prenatal stress and other developmental factors from the prenatal, childhood, and adolescent periods that have been associated with depression and/or maternal prenatal stress. LCA identified subgroups that were compared to determine whether and to what extent they differed on adolescent depressive symptoms. LCA revealed a subgroup of "high-risk" individuals, characterized by maternal factors during pregnancy (higher ambivalence/negativity and lower positivity towards the pregnancy, higher levels of hassles, lower maternal education and higher maternal age at birth, higher pre-pregnancy BMI) and offspring developmental factors (decreased cognitive functioning during childhood and adolescence, lower perceived parental support during adolescence, and higher levels of maternal depression during adolescence). High-risk females exhibited elevated conduct symptoms and higher birth order, while high-risk males exhibited decreased internalizing symptoms and lower birth order. Both high-risk males and females reported elevated depressive symptoms during adolescence relative to their "low-risk" counterparts.

Clinical theories posit interpersonal stress as an important factor in the emergence and exacerbation of depression and anxiety, while neuroendocrine research confirms the association of these syndromes with dysregulation in a major stress response system, the hypothalamic-pituitary-adrenal (HPA) axis. However, the proposal that depression and anxiety symptoms and diagnoses are associated with problematic HPA responses to close relationship stress has not been directly tested. We examined 196 heterosexual dating couples' depression and anxiety symptoms and diagnoses, assessed with questionnaires and diagnostic interviews, in relation to cortisol responses to discussion of an unresolved relationship conflict. Participants provided seven salivary samples in anticipation of and directly following the discussion, and throughout an hour-long recovery period, which were assayed for cortisol. Multilevel models of the HPA response predicted by symptoms or diagnoses showed that women's depressive symptoms predicted attenuated cortisol levels, with a flatter response curve. In contrast, men's depression symptoms and women's anxiety symptoms and diagnoses predicted higher cortisol levels. These findings highlight the importance of examining sex differences in responses to interpersonal stressors for understanding HPA dysregulation in internalizing psychopathology.

Depression seriously affects one's ability to perform work tasks and function at work. We studied the impact of both the individual and work factors on work ability index in patients suffering from depression. The prospective study, which was conducted by using questionnaires, included 210 patients with depression, who had been on sick leave from 60 to 360 days. The individual factors were evaluated by the standardized abridged form of Occupational Stress Questionnaire, while the work place factors in relation to work ability were evaluated by the work ability index. Poor work ability was observed in 151 (71%) of subjects suffering from depression. All workplace stresses, lack of support by colleagues and supervisors, ergonomically not adjusted work and huge work load are statistically associated with poor work ability index (P=0.001). More than 95% of variables of the evaluated work ability index are the result of varying in the group of stresses at work place (R2=0.95). Perception of bad health condition (Rsq=0.412, P=0.001), low level of life satisfaction (Rsq=0.309, P=0.001), low level of motivation and work knowledge (Rsq=0.309, P=0.001) are predictors for poor work ability. The work ability cannot be related with age and sex. The key activities for maintaining the work ability at the times when epidemic of depression emerges, as it is nowadays, are timely carrying out the psycho-treatments, mental and professional rehabilitation, occupational therapy and adapted work place.

Although the relation between stressful life events (SLEs) and risk of major depressive disorder is well established, important questions remain about the effects of stress on the course of geriatric depression. Our objectives were (1) to examine how baseline stress and change in stress is associated with course of geriatric depression and (2) to test whether polymorphisms of serotonin transporter (5-HTTLPR) and catechol-O-methyltransferase (COMT Val158Met) genes moderate this relation. Two-hundred and sixteen depressed subjects aged 60 years or older were categorized by remission status (Montgomery-Asberg depression rating scale≤6) at 6 and 12 months. At 6 months, greater baseline numbers of self-reported negative and total SLEs and greater baseline perceived stress severity were associated with lower odds of remission. At 12 months, only baseline perceived stress predicted remission. When we examined change in stress, 12-month decrease in negative SLEs and level of perceived stress were associated with improved odds of 12-month remission. When genotype data were included, COMT Val158Met genotype did not influence these relations. However, when compared with 5-HTTLPR L/L homozygotes, S allele carriers with greater baseline numbers of negative SLEs and with greater decrease in negative SLEs were more likely to remit at 12 months. This study demonstrates that baseline SLEs and perceived stress severity may influence the 12-month course of geriatric depression. Moreover, changes in these stress measures over time correlate with depression outcomes. 5-HTTLPR S carriers appear to be more susceptible to both the effects of enduring stress and the benefit of interval stress reduction.

To explore through literature review the appropriateness of three common tools for use by community nurses to screen war veteran and war widow(er) clients for depression, anxiety and post-traumatic stress disorder. War veterans and, to a lesser extent, war widow(er)s, are prone to mental health challenges, especially depression, anxiety and post-traumatic stress disorder. Community nurses do not accurately identify such people with depression and related disorders although they are well positioned to do so. The use of valid and reliable self-report tools is one method of improving nurses' identification of people with actual or potential mental health difficulties for referral to a general practitioner or mental health practitioner for diagnostic assessment and treatment. The Geriatric Depression Scale, Depression Anxiety Stress Scales and Post-traumatic Stress Disorder Checklist are frequently recommended for mental health screening but the appropriateness of using the tools for screening war veteran and war widow(er) community nursing clients who are often aged and have functional impairment, is unknown. Systematic review. Current literature informs that the Geriatric Depression Scale accurately predicts a diagnosis of depression in community nursing cohorts. The three Depression Anxiety Stress Scales subscales of depression, anxiety and stress are valid; however, no studies were identified that compared the performance of the Depression Anxiety Stress Scales in predicting diagnoses of depression or anxiety. The Post-traumatic Stress Disorder Checklist predicts post-traumatic stress disorder in community cohorts although no studies meeting the selection criteria included male participants. This review provides recommendations for the use of the Geriatric Depression Scale, Depression Anxiety Stress Scales and The Post-traumatic Stress Disorder Checklist based on examination of the published evidence for the application of these screening tools in samples

Several classic studies have concluded that the accuracy of identifying uncontrollable situations depends heavily on depressive mood. Nondepressed participants tend to exhibit an optimistic illusion of control, whereas depressed participants tend to better detect a lack of control. Recently, we suggested that the different activity levels (measured as the probability of responding during a contingency learning task) exhibited by depressed and nondepressed individuals is partly responsible for...

To study depression, anxiety and stress (DAS) among adolescent school students belonging to affluent families and the factors associated with high levels of DAS. 242 adolescent students belonging to class 9-12th selected for the study. DASS-21 questionnaire was used for assessing DAS. The scores in the three domains (DAS) were found to be remarkably correlated. It was seen that depression was significantly more among the females (mean rank 132.5) than the males (mean rank 113.2), p=0.03. Depression (p=0.025), Anxiety (0.005) and Stress (pstudents. Depression and Stress were found to be significantly associated with the number of adverse events in the student's life that occurred in last one year. A significant proportion of the students were found to be having high levels of DAS and several important factors were found to be associated with them. Proactive steps at the school-level and community-level and steps for improved parent-adolescent communication are needed for amelioration of the problem.
Although the stress and stressful life events are known as the precipitation of depressive disorder, the areas of stress and types of stressful life events found in depression are varied by different socio-cultural context. Identify the stress areas, stress severity, and types of stressful life events associated with the onset of depressive disorder in Thai depressed patients. Ninety depressed and ninety non-depressed subjects, aged above 18 years old, from the Department of Psychiatry, King Chulalongkorn Memorial Hospital, were recruited into the present study between July 2007 and January 2008. All subjects completed a demographic data form, and a 1-Year Life Stress Event Questionnaire. The association between the number of stressful life events, stress areas, stress severity, types of stressful life events, and the onset of depressive disorder were analyzed by independent t-test and chi-square test. Logistic regression was performed to identify the predictors of depressive disorder. Most of the subjects were young and middle-aged women, living in Bangkok and the central region. The depressed subjects experienced more stressful life events than the non-depressed subjects (5.81 +/- 3.19 vs. 3.24 +/- 2.80 events in one year) (p stress areas (health-related, family-related, financial, occupational, and social stress), and overall stress were associated with the onset of depressive disorder (p stress in all areas were at the higher risk of depressive disorder than those with the mild stress (p stress was the stress area highest associated with the depressive disorder (OR = 5.93, 95% CI = 2.33-16.92, p stressful life events associated with the onset of depressive disorder were the medical hospitalization, medical illness leading to missing work or disturbed daily routine, change in sleeping habits, absence of recreation, arguments with spouse, sexual difficulties with spouse, family financial problems, job loss, and trouble with boss (p stress was the significant

Elevated depression and stress have been linked to greater levels of alcohol problems among young adults even after taking into account drinking level. This study attempts to elucidate variables that might mediate the relation between symptoms of depression and stress and alcohol problems, including alcohol demand, future time orientation, and craving. Participants were 393 undergraduates (60.8% female, 78.9% White/Caucasian) who reported at least 2 binge-drinking episodes (4/5+ drinks for women/men, respectively) in the previous month. Participants completed self-report measures of stress and depression, alcohol demand, future time orientation, craving, and alcohol problems. In separate mediation models that accounted for gender, race, and weekly alcohol consumption, future orientation and craving significantly mediated the relation between depressive symptoms and alcohol problems. Alcohol demand, future orientation, and craving significantly mediated the relation between stress symptoms and alcohol problems. Heavy-drinking young adults who experience stress or depression are likely to experience alcohol problems, and this is due in part to elevations in craving and alcohol demand, and less sensitivity to future outcomes. Interventions targeting alcohol misuse in young adults with elevated levels of depression and stress should attempt to increase future orientation and decrease craving and alcohol reward value.

Pursuing higher education is not an easy task as it requires hard work, dedication, and motivation. Although there are many rewards involved in growing up academically, nevertheless, it contains a few hazards too. For instance, suicidal ideation is associated with presence of depression, anxiety, and stress with low level of satisfaction with life in students finding difficulty in handling educational demands of higher education. Therefore, the present study focused on the query that whether there is any difference or not among medical, engineering, and social sciences students of city of Karachi, Pakistan in the level of suicidal ideation, depression, anxiety, stress, and life satisfaction. Using comparative group design, total 300 students (150 males and 150 females) with age range of 19-26 were selected from faculties of medical, engineering, and social sciences of different universities of Karachi, Pakistan, through purposive sampling. Respondent Profile Form, The Suicide Behaviours Questionnaire-Revised, Depression Anxiety Stress Scale-21, and Satisfaction with Life Scale were administered to assess suicidal ideation; depression, anxiety, stress; and life satisfaction, respectively, of the students. Scores were analysed through ANOVA and Post Hoc (Tukey's HSD) test using SPSS. Social sciences and engineering students were significantly higher on depression, anxiety, and stress than medical students [F (2, 297) =8.701, p=.000] whereas insignificant differences in the level of suicidal ideation [F (2, 297) =1.914, p=.149] and life satisfaction [F (2, 297) = .726, p = .485] among these students were found. With the help of these findings, it would be easier to counsel students of different disciplines in time on the lines of suggested preventive measures.

Full Text Available Objective: To evaluate changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Methods: This cohort study involved patients enrolled in a smoking cessation program in Cuiabá, Brazil. We selected patients who completed the program in six months or less (n = 142. Patient evaluations were conducted at enrollment (evaluation 1 [E1]; after 45 days of treatment with medication and cognitive-behavioral therapy (E2; and at the end of the six-month study period (E3. Patients were evaluated with a standardized questionnaire (to collect sociodemographic data and determine smoking status, as well as with the University of Rhode Island Change Assessment scale, Beck Anxiety Inventory, Beck Depression Inventory, and Lipp Inventory of Stress Symptoms for Adults. The data were analyzed with the nonparametric Wilcoxon test for paired comparisons. To compare treatment success (smoking cessation with treatment failure, the test for two proportions was used. Results: Among the 142 patients evaluated, there were improvements, in terms of the levels of anxiety, depression, motivation, and stress, between E1 and E2, as well as between E1 and E3. In addition, treatment success correlated significantly with the levels of motivation and anxiety throughout the study period, whereas it correlated significantly with the level of depression only at E2 and E3. Conclusions: We conclude that there are in fact changes in the levels of patient anxiety, depression, motivation, and stress over the course of smoking cessation treatment. Those changes appear to be more pronounced in patients in whom the treatment succeeded.

Globally, graduate students have been found to have high prevalence of mental health problems. With increasing severity of mental health problems on university campuses and limited resources for mental health treatment, alternative interventions are needed. This study investigated the use of biofeedback training to help reduce symptoms of stress, anxiety, and depression. A sample of 60 graduate students in public health nursing was randomly assigned to either the biofeedback intervention or the control group. Results indicated that biofeedback intervention was effective in significantly reducing the levels of stress, anxiety, and depression over the 4-week period, while the control group had increases in symptoms of anxiety and depression over the same timeframe. As future leaders in the public health nursing arena, the more psychologically healthy the graduate students in public health nursing are, the better the public health nursing professionals they will be as they go forth to serve the community after graduation.

Full Text Available Cortical spreading depression (CSD is closely associated with important pathologies including stroke, seizures and migraine. The mechanisms underlying SD in its various forms are still incompletely understood. Here we describe SD-like events in an invertebrate model, the ventilatory central pattern generator (CPG of locusts. Using K(+ -sensitive microelectrodes, we measured extracellular K(+ concentration ([K(+](o in the metathoracic neuropile of the CPG while monitoring CPG output electromyographically from muscle 161 in the second abdominal segment to investigate the role K(+ in failure of neural circuit operation induced by various stressors. Failure of ventilation in response to different stressors (hyperthermia, anoxia, ATP depletion, Na(+/K(+ ATPase impairment, K(+ injection was associated with a disturbance of CNS ion homeostasis that shares the characteristics of CSD and SD-like events in vertebrates. Hyperthermic failure was preconditioned by prior heat shock (3 h, 45 degrees C and induced-thermotolerance was associated with an increase in the rate of clearance of extracellular K(+ that was not linked to changes in ATP levels or total Na(+/K(+ ATPase activity. Our findings suggest that SD-like events in locusts are adaptive to terminate neural network operation and conserve energy during stress and that they can be preconditioned by experience. We propose that they share mechanisms with CSD in mammals suggesting a common evolutionary origin.

Agmatine has been recently emerged as a novel candidate to assist the conventional pharmacotherapy of depression. The acute restraint stress (ARS) is an unavoidable stress situation that may cause depressive-like behavior in rodents. In this study, we investigated the potential antidepressant-like effect of agmatine (10mg/kg, administered acutely by oral route) in the forced swimming test (FST) in non-stressed mice, as well as its ability to abolish the depressive-like behavior and hippocampal antioxidant imbalance induced by ARS. Agmatine reduced the immobility time in the mouse FST (1-100mg/kg) in non-stressed mice. ARS caused an increase in the immobility time in the FST, indicative of a depressive-like behavior, as well as hippocampal lipid peroxidation, and an increase in the activity of hippocampal superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GR) activities, reduced catalase (CAT) activity and increased SOD/CAT ratio, an index of pro-oxidative conditions. Agmatine was effective to abolish the depressive-like behavior induced by ARS and to prevent the ARS-induced lipid peroxidation and changes in SOD, GR and CAT activities and in SOD/CAT activity ratio. Hippocampal levels of reduced glutathione (GSH) were not altered by any experimental condition. In conclusion, the present study shows that agmatine was able to abrogate the ARS-induced depressive-like behavior and the associated redox hippocampal imbalance observed in stressed restraint mice, suggesting that its antidepressant-like effect may be dependent on its ability to maintain the pro-/anti-oxidative homeostasis in the hippocampus.

When exposed to stressful life events, a significant number of adolescents will experience depressive symptoms. One model of depression suggests that individuals with a negative cognitive style are most vulnerable to depression following life stress. Alternatively, altered activation of the hypothalamic-pituitary-adrenal axis may explain vulnerability to depression following life stress. Each of these models plausibly explains the emergence of depressive symptoms during adolescence and have been investigated largely independently. The current study recruited a sample of urban adolescents (N = 179) to evaluate whether cortisol response to a laboratory stress induction and negative cognitive style are related and whether they independently interact with exposure to stressful life events to predict symptoms of depression. Negative cognitive style was not associated with cortisol response to the laboratory stressor. Rather, negative cognitive style and cortisol recovery independently interacted with stressful life events to predict current symptoms of depression. Results support a heterogeneous etiology of depression.

The aim of the current study was to determine whether the serum prolidase levels are associated with the etiopathogenesis of depression. This study included 29 patients with major depressive disorder (MDD), who were consecutively recruited from the psychiatric outpatient clinic, and 30 healthy individuals recruited from the general community. Each patient underwent a detailed diagnostic evaluation by two psychiatrists using the Structured Clinical Interview for DSM-IV (SCID-I). Serum prolidase activity and oxidative parameters were measured in the patient and control groups. The severity of depressive symptoms was assessed using the Hamilton Depression Rating Scale. Serum prolidase level was significantly higher in patients with MDD compared to healthy subjects (pStress Index (OSI) were also significantly higher in patients with MDD (pstress in patients with MDD. Increased serum prolidase levels in patients with MDD may be interpreted as the interaction of prolidase activity, glutamate transmission and oxidative stress. It is suggested that prolidase activity is involved in the etiopathogenesis of depressive disorder.

To determine whether anxiety or depression is associated with takotsubo stress cardiomyopathy (TSCM). A retrospective case-control study was conducted among 73 TSCM cases and 111 acute coronary syndrome (ACS) controls matched for age, sex, and cardiac catheterization date. The study was conducted between May 1, 2009, and February 28, 2010. The Hospital Anxiety and Depression Scale was completed by all participants after hospital discharge. The Hospital Anxiety and Depression Scale was used to assess psychological distress with measurement of anxiety and depression scores. The presence of a stressful emotional or physical trigger before the TSCM presentation was determined. Univariate testing was performed to quantify the associations between anxiety and depression and TSCM trigger status. Multivariable logistic regression was used to quantify the independent associations between anxiety and depression and TSCM status after controlling for relevant covariates. The mean anxiety score was 6.7 ± 4.7 for TSCM cases versus 5.4 ± 3.4 for ACS controls (P = .06). The mean depression score was 4.3 ± 3.7 for TSCM cases versus 4.0 ± 3.1 for controls (P = .61). Anxiety was particularly associated with TSCM status with an emotional trigger (P = .05). After multivariable adjustment, anxiety (OR = 1.13; 95% CI, 1.01-1.26; P = .03) was associated with TSCM status but depression was not (OR = 0.94; 95% CI, 0.83-1.05; P = .29). In comparison with a control group with ACS, patients who presented with TSCM have higher levels of anxiety but not depression.

Major depressive disorder (MDD) is often associated with dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis by chronic stress. In comparison, psychosocial stress-induced activation of salivary α-amylase (sAA) functions as a marker of sympathoadrenal medullary system (SAM) activity. However, in contrast to salivary cortisol, sAA has been less extensively studied in MDD patients. The present study measured sAA and salivary cortisol levels in patients with MDD. The authors determined Profile of Mood State (POMS) and State-Trait anxiety Inventory (STAI) scores, Heart Rate Variability (HRV), and sAA and salivary cortisol levels in 88 patients with MDD and 41 healthy volunteers following the application of electrical stimulation stress. Patients with major depressive disorder were 8 points or more on Hamilton Depression Scale (HAM-D) scores. Tension-Anxiety, Depression-Dejection, Anger-Hostility, Fatigue, and Confusion scores in patients with major depressive disorder were significantly increased compared to healthy controls. In contrast, Vigor scores in patients with MDD were significantly decreased compared with healthy controls. There was no difference in heart rate variability measures between MDD patients and healthy controls. The threshold of electrical stimulation applied in MDD patients was lower than that in healthy controls. SAA levels in female MDD patients were significantly elevated relative to controls both before and after electrical stimulation. Finally, there were no differences in salivary cortisol levels between major depressive patients and controls. In the present study only three time points were explored. Furthermore, the increased secretion of sAA before and after stimulation could allude to an increased responsiveness of novel and uncontrollable situations in patients with MDD. These preliminary results suggest that sAA might be a useful biological marker of MDD. Copyright © 2011 Elsevier Inc. All rights reserved.

The psychometric properties of the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995a) were examined in depressed psychiatric hospital samples. Three studies administered the DASS and other symptom measures at admission and discharge to consecutive adult hospital patients with a primary diagnosis of depression. Study 3 aimed to address problems with the DASS by extending the response options. Study 1 found that the DASS had good reliability and validity, was moderately sensitive to change, but the Depression Scale exhibited a ceiling effect. In Study 2, confirmatory factor analysis supported a three-factor structure and the DASS continued to demonstrate good psychometric properties, but the ceiling effect was replicated. Study 3 found that by extending the response scale to include an additional option, the factor structure of the instrument as a whole was maintained, the sensitivity to treatment was increased, but the ceiling effect was only marginally reduced. The psychometric properties of the DASS were sound in clinically depressed samples, but the Depression Scale exhibited a ceiling effect that could not be resolved with minor changes to the scale. Suggestions for revisions of the DASS are made.

To assess the relationships between migraine, depression, anxiety, stress, and sleep problems. Psychiatric conditions and sleep disturbances are common in migraineurs. Depression, anxiety, stress, migraine, and sleep problems frequently coexist as comorbidities. Eighty-seven episodic migraineurs (62 females, 25 males; 32.8 ± 6.9) and 41 control subjects (25 females, 16 males; 31.5 ± 5.6) were prospectively enrolled for the study. The participants completed a sociodemographic data form and a migraine disability assessment scale (MIDAS), depression, anxiety, stress scale (DASS), and Pittsburg Sleep Quality Index (PSQI). In migraineurs, a significant positive correlation was found between PSQI total scores and MIDAS scores (migraine related disability for at least three consecutive months) (r = 0. 234, p = 0.04). Only 24.1 % of migraineus (n = 21) had minimal or no disability, 75.9 % of the patients (n = 66) had more than a little disability according to MIDAS scores. PSQI total scores were also correlated with pain intensity over a three month period (MIDAS B) (r = 0.221, p = 0.04). While PSQI scores were found significantly different between migraineurs and control subjects (5.5 ± 2.9 vs 4.5 ± 2.5; p = 0.04), the correlation of all the DASS subscale scores between the groups was not statistically significant. Our findings showed that episodic migraine was a risk factor on its own for sleep disturbances without comorbid depression, anxiety, and stress. Moreover, migraine-related disability and pain intensity in migraine attacks were related to poor sleep quality.

To measure levels of parenting stress and postnatal depression in mothers of very preterm infants in comparison with mothers of infants born at term is the objective of this study. The study also aimed to explore factors associated with parenting stress in the mothers of the preterm infants. One hundred and five mothers who delivered 124 babies at ≤30 weeks gestation were enrolled together with 105 term mothers who delivered 120 babies. At one year of age (corrected for prematurity for the preterm cohort), the mothers completed the Parenting Stress Index Short Form (PSI), the Edinburgh Postnatal Depression Scale (EPDS) and the Short Temperament Scale for Toddlers. The infants had neurodevelopmental assessment. The preterm and term groups were compared. Questionnaires were completed by 101 of the preterm mothers and 98 of the term mothers. The mean PSI Total Stress score was significantly higher for the preterm mothers (70.28 vs 64.52, p = 0.022), with 19% of the preterm group and 9% of the term group having high scores (p = 0.038).There was no group difference on the EPDS or measures of temperament, with disability being greater in the preterm infants. For the preterm group, maternal depression and infant temperament were independent predictors of Total Stress scores on multivariate analysis. Parenting stress in mothers of preterm infants at one year of age is significantly greater than that found in mothers of term infants. For preterm mothers, symptoms of depression and infant temperament are independent risk factors for higher levels of parenting stress. Copyright © 2013 Elsevier Ltd. All rights reserved.

Previous studies have demonstrated that repeated restraint stress in rodents produces increases in depression and anxietylike behaviors and alters the expression of corticotrophinreleasing factor (CRF) in the hypothalamus. The current study focused on the impact of Bupleurum falcatum (BF) extract administration on repeated restraint stress-induced behavioral responses using the forced swimming test (FST) and elevated plus maze (EPM) test. Immunohistochemical examinations of tyrosine hydroxylase (TH) expression in rat brain were also conducted. Male rats received daily doses of 20, 50, or 100 mg/kg (i.p.) BF extract for 15 days, 30 min prior to restraint stress (4 h/day). Hypothalamicpituitary- adrenal axis activation in response to repeated restraint stress was confirmed base on serum corticosterone levels and CRF expression in the hypothalamus. Animals that were pre-treated with BF extract displayed significantly reduced immobility in the FST and increased open-arm exploration in the EPM test in comparison with controls. BF also blocked the increase in TH expression in the locus coeruleus of treated rats that experienced restraint stress. Together, these results demonstrate that BF extract administration prior to restraint stress significantly reduces depression and anxiety-like behaviors, possibly through central adrenergic mechanisms, and they suggest a role for BF extract in the treatment of depression and anxiety disorders.

Treatment-resistant depression (TRD) remains a pressing clinical problem. Optimizing treatment requires better definition of the specificity of the involved brain circuits. The rat strain bred for negative cognitive state (NC) represents a genetic animal model of TRD with high face, construct and predictive validity. Vice versa, the positive cognitive state (PC) strain represents a stress-resilient phenotype. Although NC rats show depressive-like behavior, some symptoms such as anhedonia require an external trigger, i.e. a stressful event, which is similar to humans when stressful event induces a depressive episode in genetically predisposed individuals (gene-environment interaction). We aimed to distinguish neurobiological predisposition from the depressogenic pathology at the level of brain-network reorganization. For this purpose, resting-state functional magnetic resonance imaging time series were acquired at 9.4 Tesla scanner in NC (N=11) and PC (N=7) rats before and after stressful event. We used a graph theory analytical approach to calculate the brain-network global and local properties. There was no difference in the global characteristics between the strains. At the local level, the response in the risk strain was characterized with an increased internodal role and reduced local clustering and efficiency of the anterior cingulate cortex (ACC) and prelimbic cortex compared to the stress-resilient strain. We suggest that the increased internodal role of these prefrontal regions could be due to the enhancement of some of their long-range connections, given their connectivity with the amygdala and other default-mode-like network hubs, which could create a bias to attend to negative information characteristic for depression.

Bergamot essential oil (BEO) possesses sedation and anxiolytic properties similar to diazepam. After long period of exposure to stressors, including restrained stress, depressive-like behavior can be produced. BEO has been suggested to reduce depression. However, there is no scientific evidence supporting this property. To investigate the effect of BEO in chronic stressed rats on: 1) behavior related depressive disorder, 2) hypothalamic pituitary adrenal (HPA) axis response, and iii) brain-derived neurotrophic factor (BDNF) protein levels in hippocampus. Male Wistar rats, weighing 200 to 250 g, were induced chronic restrained stress 15 minutes dailyfor two weeks. For the next two weeks, these rats were divided intofour groups, control-i.p., fluoxetine-i.p., control-inhale, and BEO-inhale. Fluoxetine (10 mg/kg i.p.) or saline was intraperitoneally administered daily while 2.5% BEO or saline was inhaled daily. At the end of the treatment, rats were assessed for depressive-like behavior using the forced swimming test (FST). After the behavioral test, the animals were immediately decapitated and trunk blood samples were collected for the measurement ofcorticosterone and adrenocorticotropic hormone (ACTH) levels and hippocampus was dissected and stored in afreezer at -80 °C until assay for BDNF protein. BEO andfluoxetine significantly decreased the immobility time in the FST (p BDNF protein determination, neither BEO norfluoxetine had any effect on BDNF protein levels in hippocampus compared to their controls. The inhalation ofBEO decrease behavior related depressive disorder similar tofluoxetine but has no effect on HPA axis response and BDNF protein levels in chronic restrained stress.

Alterations of hypothalamic-pituitary-adrenal (HPA) function are well-established in adults with current depression. HPA alterations may persist into remission and confer increased risk for recurrence. A modified version of the Trier Social Stress Test (TSST) was administered at baseline to 32 young adults with remitted major depressive disorder and 36 never-depressed controls. Participants were randomly assigned to either a 'high-stress' condition involving social evaluation or a 'low-stress' control condition. Cortisol concentrations were measured in saliva samples throughout the TSST. Participants were assessed again after 6 months for the occurrence of stressful life events and depressive symptoms/disorders during the follow-up period. Participants who exhibited enhanced cortisol reactivity in the low-stress condition showed increases in depressive symptoms over follow-up, after controlling for stressful life events during the follow-up period. Anticipatory stress cortisol and cortisol reactivity each interacted with history of depressive episodes to predict depression trajectories. The single TSST administration limits conclusions about whether alterations of cortisol reactivity represent trait-like vulnerability factors or consequences ("scars') of past depression. These results extend previous findings on stress sensitivity in depression and suggest that altered HPA function during remission could reflect an endophenotype for vulnerability to depression recurrence. Findings support interactive models of risk for depression recurrence implicating HPA function, depression history, and sensitivity to minor stressors. Results may have implications for interventions that match treatment approaches to profiles of HPA function. Copyright © 2012 Elsevier B.V. All rights reserved.

Depression is prevalent among individuals with diabetes and associated with suboptimal self-management. Little is known about the feasibility and potential impact of tele-behavioral therapy to improve depressive symptoms and self-management among diabetes patients. This was a retrospective observational study of consecutive graduates enrolled in a national 8-week diabetes behavioral telehealth program between August 1, 2014, and January 31, 2015 (N = 466; mean age 56.8 ± 5.0 years; 56% female). Participant characteristics (demographics, comorbidities) were obtained by standardized questionnaire. Depression, anxiety, and stress symptoms (DASS; validated Depression Anxiety and Stress Scale 21 survey), and glucose self-testing frequency and values (point-of-care monitor) were measured at program start and completion. Changes in DASS severity and glucose self-testing frequency were assessed by chi-square tests. Changes in DASS and blood glucose levels were evaluated by paired t-tests. At baseline, approximately one in three participants had elevated depression (32%), anxiety (33%), or stress (31%) scores. Significant reductions in average DASS, depression (-8.8), anxiety (-6.9), and stress (-9.9), scores were observed at graduation among those with elevated baseline scores (p depression, anxiety, or stress categories. Improved glucose self-testing frequency (69% vs. 60% tested ≥once per week; p = 0.0005) and significant reductions in mean morning glucose levels (-12.3 mg/dL; p = 0.0002) were observed from baseline to graduation. Participants with normal versus non-normal depression scores were more likely to have lower (depression, anxiety, stress, and glucose levels, as well as increased frequency of glucose self-testing, among participants in a diabetes behavioral telehealth program.
Full Text Available Objective: The aim of this research was to find out the effect of the Information Phase of a Stress Management Program (SMP on the perceptions of participants about their stress levels. Method: A total sample of 100 workers (nursing staff, private business men and women, laboratory assistants, the protective services [foreman and security staff], as well as people in human resources departments took part in this study. All the participants were from the Northern and Gauteng Provinces in South Africa. The Combined Hassles and Uplifts Scale (Folkman & Lazarus, 1989 was used as an instrument to measure the perceived stress level of participants in a SMP. Result: A significant reduction in stress levels was achieved among those who received the Information Phase of the SMP only, as well as those who received the whole stress management techniques. There was no significant difference between the amount of reduction in perceived stress-levels achieved among those that received the Information Phase of the SMP only, compared to that of those who received the whole techniques. Conclusion: The authors conclude that where the resources are limited, only the information phase of a SMP may be given to desiring clients. That should help to save time and money spent on participating in SMPs. This should however not discourage the use of the whole SPM, where affordable. Keywords: Stress Management Programs, Information Phase, Perception, Stress Level.

The purpose of the current study was to examine the mutual relationships between dyadic level (i.e., marital quality and parenting stress) and individual level factors (i.e., children and parental depressive symptoms) in families of children with Oppositional Defiant Disorder (ODD). Specifically, we explored whether marital interaction (marital quality) was associated with symptoms of child depression through parent-child interaction (parenting stress) and parent depressive symptoms. We also explored whether parent-child interaction was associated with symptoms of parent depression through marital interaction and child depressive symptoms. This study was conducted with 256 parent-child dyads, consisting of children with ODD and one of each child's parents. Participants were recruited from 14 primary schools located in northern, eastern, and southwestern China. Results revealed that marital quality predicted symptoms of child depression through the parenting stress, but not parent depressive symptoms; and parenting stress predicted symptoms of parent depression through marital quality, but not through child depressive symptoms. Also, parenting stress significantly and directly predicted parent depressive symptoms. We concluded in families of children with ODD, the association of marital interaction and parent-child interaction on both symptoms of parent and child depression highlighted the mutual effects of the couple subsystem and the parent-child subsystem. Furthermore, in regard to parental and child depressive symptoms, implications for intervention are provided.

Alfaisal University in Riyadh, Saudi Arabia is a developing institution; hence, there has been a concern regarding the mental well-being of the students.Objectives: This study was designed to assess the traits of depression, anxiety, and stress among students in relation to potential underlying reasons.Methods: All 575 medical students across the 5 years of study participated by filling out the Depression, Anxiety, and Stress Scale-21 (DASS-21 questionnaire anonymously twice. Firstly, 2–3 weeks before a major examination (pre-examination, and secondly, during regular classes (post-examination. Correlation was sought regarding sex, year of scholarship, attendance of a premedical university preparatory program (UPP, housing, and smoking. Subjective comments from students were also obtained.Results: A total of 76.8% and 74.9% of students participated in pre- and post-examination groups, respectively. The majority were the children of expatriate workers in Saudi Arabia, and included Arabs, South Asians, and North Americans. Prevalence of depression, anxiety, and stress was high (43%, 63%, and 41%, respectively which reduced (to 30%, 47%, and 30%, respectively to some extent after examinations. Saudis and those who had attended UPP had higher DASS-21 scores. Smoking and female sex predicted higher levels of “baseline” depression, anxiety, or stress. The students perceived the curriculum and schedule to be the primary causes of their high DASS-21 scores.Conclusion: The students had high “baseline” traits of depression, anxiety, and stress, and these were higher if an examination was near, especially among Saudis and those who had attended UPP.

Full Text Available Transition to parenthood represents an important life event increasing vulnerability to psychological disorders. Postpartum depression and parenting distress are the most common psychological disturbances and a growing scientific evidence suggests that both mothers and fathers are involved in this developmental crisis. This paper aims to explore maternal and paternal experience of transition to parenthood in terms of parenting distress and risk of postpartum depression. Seventy-five couples of first-time parents were invited to compile the Edinburgh Postnatal Depression Scale and the Parenting Stress Index-Short Form in the first month of children life. Study sample reported very high levels of parenting distress and a risk of postpartum depression in 20.8% of mothers and 5.7% of fathers. No significant correlation between parenting distress and the risk of postpartum depression emerged, both in mothers than in fathers group while maternal distress levels are related to paternal one. The first month after partum represents a critical phase of parents life and it could be considered a developmental crisis characterized by anxiety, stress and mood alterations that could have important repercussions on the child psycho-physical development.

Our previous study has reported that the proactive secretion and role of central high mobility group box 1 (HMGB1) in lipopolysaccharide-induced depressive behavior. Here, the potential mechanism of HMGB1 mediating chronic-stress-induced depression through the kynurenine pathway (KP) was further explored both in vivo and in vitro. Depression model was established with the 4-week chronic unpredictable mild stress (CUMS). Sucrose preference and Barnes maze test were performed to reflect depressive behaviors. The ratio of kynurenine (KYN)/tryptophan (Trp) represented the enzyme activity of indoleamine-2,3-dioxygenase (IDO). Gene transcription and protein expression were assayed by real-time RT-PCR and western-blot or ELISA kit respectively. Along with depressive behaviors, HMGB1 concentrations in the hippocampus and serum substantially increased post 4-week CUMS exposure. Concurrent with the upregulated HMGB1 protein, the regulator of translocation of HMGB1, sirtuin 1 (SIRT1) concentration in the hippocampus remarkably increased. In addition to HMGB1 and SIRT1, IDO, the rate limiting enzyme of KP, was upregulated at the level of mRNA expression and enzyme activity in stressed hippocampi and LPS/HMGB1-treated hippocampal slices. The gene transcription of kynurenine monooxygenase (KMO) and kynureninase (KYNU) in the downstream of KP also increased both in vivo and in vitro. Mice treated with ethyl pyruvate (EP), the inhibitor of HMGB1 releasing, were observed with lower tendency of developing depressive behaviors and reduced activation of enzymes in KP. All of these experiments demonstrate that the role of HMGB1 on the induction of depressive behavior is mediated by KP activation. Copyright © 2017 Elsevier Inc. All rights reserved.

Nursing students are valuable human resources. Detection of potential depression among nursing students is crucial since depression can lead to low productivity, minimized quality of life, and suicidal ideas. Identifying factors affecting depression among students can help nursing educators to find ways to decrease depression. The purpose of this study was to examine rates of depression and the associations between depression and stress, emotional support, and self-esteem among baccalaureate nursing students in Thailand. This correlational, cross-sectional study recruited 331 baccalaureate Thai nursing students. Students completed three instruments that had been translated into Thai: The Center for Epidemiology Studies Depression Scale, Perceived Stress Questionnaire, and Rosenberg Self-Esteem Scale. Another instrument created in Thai was used to measure emotional support. Results revealed that, when using the standard definition, 50.1% of the students were depressed. Stress was positively related to depression, whereas emotional support and self-esteem were negatively related to depression.

Our study aims to estimate the prevalence of symptoms of depression and daily life hassles in elite athletes. A cross-sectional prospective epidemiological study design. An online anonymous survey was administered during a 2-month period from May to July 2015. Athletes 18 years of age (or older) who were members of the High Performance Sport New Zealand programme were invited to participate. Of 370 potential participants, 187 completed responses were received (51%). Symptoms of depression were measured by the Centre for Epidemiological Studies Depression Scale-Revised (CESD-R). Life stress was measured by the Daily Hassles Questionnaire. Overall 21% (n=39) of participants reported symptoms consistent with depression. Only 2 of the 39 athletes were currently taking an anti-depressant medication. Those contemplating retirement, partaking in individual sport, and who were less than 25 years old had significantly increased odds of experiencing depression. Reported life stressors were higher in females, in those who play an individual sport and those in a centralised programme. There was a significant correlation between higher levels of life stress and experiencing depressive symptoms. This study highlights that depressive symptoms are prevalent in elite athletes with multiple potential risk factors identified including high life stress. These variables warrant further exploration to enable the early identification of athletes with depressive symptoms, screening and support for elite athletes.

Full Text Available Experimental models of depression often entail exposing a rodent to a stressor and subsequently characterizing changes in learning and anhedonia, which may reflect symptoms of human depression. Importantly, not all people and not all laboratory rats exposed to stressors develop depressed behavior; these resilient individuals are the focus of our review. Herein we describe research from the learned helplessness and intermittent swim stress models of depression in which rats that were allowed to cope with the stressor appear to be behaviorally and neurochemically similar to rats that were not allowed to cope yet appeared resilient in behavioral tests. For example, rats exposed to inescapable tailshock, but do not develop learned helplessness, exhibit altered sensitivity to the behavioral effects of GABAA receptor antagonists and reduced in vitro benzodiazepine receptor ligand binding. This pattern suggested that resilience might involve activation of an endogenous benzodiazepine-like compound, possibly an allostatic modulator of the GABAA receptor like allopregnanolone. From the intermittent swim stress model, we have observed in resilient rats protection from stressor-induced glucocorticoid increases and immune activation. In order to identify the neural mediators of these correlates of resilience, non-invasive measures are needed to predict the resilient or vulnerable phenotype prior to analysis of neural endpoints. To this end, we found that ultrasonic vocalizations (USVs appear to predict the resilient phenotype in the intermittent swim stress paradigm. We propose that combining non-invasive predictive measures, such as USVs with biological endpoint measures, will facilitate future research into the neural correlates of resilience.

Full Text Available Rumination in response to stress (stress-reactive rumination has been linked to higher levels of depressive symptoms in adolescents. However, no work to date has examined the neural mechanisms connecting stress-reactive rumination and adolescent depressive symptoms. The present work attempted to bridge this gap through an fMRI study of 41 adolescent girls (Mage = 15.42, SD = 0.33 – a population in whom elevated levels of depressive symptoms, rumination, and social stress sensitivity are displayed. During the scan, participants completed two tasks: an emotion regulation task and a social stress task. Using psychophysiological interaction (PPI analyses, we found that positive functional connectivity between the amygdala and ventrolateral prefrontal cortex (VLPFC during the emotion regulation task mediated the association between stress-reactive rumination and depressive symptoms. These results suggest that stress-reactive rumination may interfere with the expression and development of neural connectivity patterns associated with effective emotion regulation, which may contribute, in turn, to heightened depressive symptoms.

This study investigated whether an Expressive Writing intervention decreased depression and posttraumatic stress symptoms after childbirth. 113 women (M age = 31.26 yr., SD = 4.42) were assessed at Time 1 for depression (Beck Depression Inventory) and PTS (Perinatal PTSD Questionnaire) in the first days after childbirth, then randomized to either expressive writing or neutral writing conditions and reassessed at Time 2, 3 months later. The results (ANCOVAs, regression models) show that at 3 mo. depressive and posttraumatic symptoms were lower in women who performed the expressive writing task than in the neutral writing group. Moreover, the intervention condition was associated significantly with decreased depression at the high and at the mean levels of baseline depression at Time 1. Regarding PTSD, the results showed that the intervention condition was linked significantly to reductions of the symptoms at all levels of baseline PTSD. Mainly, these outcomes suggest that Expressive Writing can be a helpful early and low-cost universal intervention to prevent postpartum distress for women.

To compare the prevalence of anxiety, depression, and stress in medical students from all semesters of a Brazilian medical school and assess their respective associated factors. A cross-sectional study of students from the twelve semesters of a Brazilian medical school was carried out. Students filled out a questionnaire including sociodemographics, religiosity (DUREL - Duke Religion Index), and mental health (DASS-21 - Depression, Anxiety, and Stress Scale). The students were compared for mental health variables (Chi-squared/ANOVA). Linear regression models were employed to assess factors associated with DASS-21 scores. 761 (75.4%) students answered the questionnaire; 34.6% reported depressive symptomatology, 37.2% showed anxiety symptoms, and 47.1% stress symptoms. Significant differences were found for: anxiety - ANOVA: [F = 2.536, p=0.004] between first and tenth (p=0.048) and first and eleventh (p=0.025) semesters; depression - ANOVA: [F = 2.410, p=0.006] between first and second semesters (p=0.045); and stress - ANOVA: [F = 2.968, p=0.001] between seventh and twelfth (p=0.044), tenth and twelfth (p=0.011), and eleventh and twelfth (p=0.001) semesters. The following factors were associated with (a) stress: female gender, anxiety, and depression; (b) depression: female gender, intrinsic religiosity, anxiety, and stress; and (c) anxiety: course semester, depression, and stress. Our findings revealed high levels of depression, anxiety, and stress symptoms in medical students, with marked differences among course semesters. Gender and religiosity appeared to influence the mental health of the medical students.

This study examines the prevalence of depression, anxiety and symptoms of stress among baccalaureate nursing students in Hong Kong. Recent epidemiological data suggest that the prevalence of mild to severe depression, anxiety and stress among qualified nurses in Hong Kong stands at 35.8%, 37.3% and 41.1%, respectively. A total of 661 nursing students were recruited to participate in our cross-sectional mental health survey using the Depression, Anxiety and Stress Scale 21. Multiple logistic regression was used to determine significant relationships between variables. Working in general medicine, being in financial difficulty, having sleep problems, not having leisure activity and perceiving oneself in poor mental health were significant correlates of past-week depression, anxiety and stress. Year of study, physical inactivity and family crisis in the past year correlated significantly with depression. Imbalanced diets significantly correlated with anxiety. Stress was significantly associated with a lack of alone time. This is the first study to confirm empirically that clinical specialty, financial difficulties and lifestyle factors can increase nursing students' levels of depression and anxiety and symptoms of stress. Prevention, including the early detection and treatment of mental disorder, promises to reduce the prevalence of these indicators among this group.

Life stress consistently increases the incidence of major depression. Recent evidence has shown that individual symptoms of major depressive disorder (MDD) differ in important dimensions such as their genetic and etiological background, but the impact of stress on individual MDD symptoms is not known. Here, we assess whether stress affects depression symptoms differentially. We used the chronic stress of medical internship to examine changes of the nine Diagnostic and Statistical Manual (DSM)-5 criterion symptoms for depression in 3021 interns assessed prior to and throughout internship. All nine depression symptoms increased in response to stress (all P stress (P Stress differentially affects the DSM-5 depressive symptoms.

Although college campuses represent strategic locations to address mental health disparity among minorities in the US, there has been strikingly little empirical work on risk processes for anxiety/depression among this population. The present investigation examined the interactive effects of acculturative stress and experiential avoidance in relation to anxiety and depressive symptoms among minority college students (n = 1,095; 78.1% female; Mage = 21.92, SD = 4.23; 15.1% African-American (non-Hispanic), 45.3% Hispanic, 32.5% Asian, and 7.1% other races/ethnicities. Results provided empirical evidence of an interaction between acculturative stress and experiential avoidance for suicidal, social anxiety, and anxious arousal symptoms among the studied sample. Inspection of the significant interactions revealed that acculturative stress was related to greater levels of suicidal symptoms, social anxiety, and anxious arousal among minority college students with higher, but not lower, levels of experiential avoidance. However, in contrast to prediction, there was no significant interaction for depressive symptoms. Together, these data provide novel empirical evidence for the clinically-relevant interplay between acculturative stress and experiential avoidance in regard to a relatively wide array of negative emotional states among minority college students.

It has been shown that asymmetric dimethylarginine (ADMA), carbonyl groups, catalase (CAT) and neurokinin A (NKA) are actively involved in neuronal processes such as depression and posttraumatic stress disorder (PTSD). One of their roles is to protect the body from oxidative damage. This is done by affecting neuronal growth, development and plasticity. The study aimed at assessing the concentrations of ADMA, carbonyl groups, CAT and NKA in patients with varying levels of depression severity, PTSD, and depression concurrent with PTSD. The study covered 460 people. Out of them, 120 suffered from different types of depression. The study groups comprised: 60 subjects with mild depression (MD), 60 subjects with moderate depression (MOD), 60 subjects with severe depression (SeD), 60 subjects with MD and PTSD (MD+PTSD), 60 subjects with MOD and PTSD (MOD+PTSD), 60 subjects with SeD and PTSD (SeD+PTSD), and 60 subjects with PTSD alone. Each group of 60 participants included 30 males and 30 females. The concentrations of all blood parameters were determined at 7 a.m. using the ELISA method. Depressive episodes became more severe as the concentration levels of studied markers increased. ADMA, carbonyl groups, CAT and NKA can be useful markers of chronic stress in both males and females with depression, PTSD, and depression concurrent with PTSD. They can be utilized when making an initial diagnosis and evaluating the severity of disease. Changes in their concentration levels may show a biological response to oxidative stress characteristic of depression. Copyright © 2017. Published by Elsevier Urban & Partner Sp. z o.o.

The aim was to study the association between stress level and chronic facial pain, while controlling for the effect of depression on this association, during a three-year follow-up in a general population-based birth cohort. In the general population-based Northern Finland 1966 Birth Cohort, information about stress level, depression and facial pain were collected using questionnaires at the age of 31 years. Stress level was measured using the Work Ability Index. Depression was assessed using the 13-item depression subscale in the Hopkins Symptom Checklist-25. Three years later, a subsample of 52 subjects (42 women) with chronic facial pain and 52 pain-free controls (42 women) was formed. Of the subjects having high stress level at baseline, 73.3% had chronic facial pain, and 26.7% were pain-free three years later. The univariate logistic regression analysis showed that high stress level at 31 years increased the risk for chronic facial pain (crude OR 6.1, 95%, CI 1.3-28.7) three years later. When including depression in a multivariate model, depression associated statistically significantly with chronic facial pain (adjusted OR 2.5, 95%, CI 1.0-5.8), whereas stress level did not (adjusted OR 2.3, 95%, CI 0.6-8.4). High stress level is connected with increased risk for chronic facial pain. This association seems to mediate through depression.

To examine in a sample of young elite athletes (a) the presence of clinically relevant symptoms of burnout and depression, and (b) a possible interaction of perceived stress and mental toughness in the prediction of burnout and depressive symptoms. 6-month prospective study. A representative sample of 257 young elite athletes (M=16.82years, SD=1.44, 36% females) was recruited in North-Western Switzerland. 197 athletes were followed-up across a 6-month period. Burnout was assessed with the Shirom-Melamed Burnout Measure (SMBM), and depression with the 9-item depression module of the Patient Health Questionnaire (PHQ). Values of ≥4.40 (SMBM) and >14 (PHQ-9) were considered indicative of clinically relevant burnout or depression. Stress perceptions were assessed with the Perceived Stress Scale (PSS), and mental toughness with the Mental Toughness Questionnaire (MTQ). Hierarchical regression analyses were used to test stress-buffering effects. The percentage of athletes with clinically relevant levels of burnout and depressive symptoms was 12% and 9%, respectively. Both cross-sectional and prospective analyses showed that compared to participants with low mental toughness, those with higher mental toughness scores reported significantly fewer mental health issues, when exposed to high stress. By contrast, when stress levels were low, mental toughness was unrelated to psychological health complaints. About every tenth young elite athlete reported burnout or depressive symptoms of potential clinical relevance. While high perceived stress was associated with increased psychological health complaints, mental toughness was able to off-set some of the negative consequences resulting from high stress exposure.

Nursing students are susceptible to a higher risk of depression. Recognition of depression, assertiveness and the relationship between them is important since if a relationship exists, probably enhancing the level of assertiveness can reduce depression in this high risk group. We aimed to investigate depression and assertiveness levels and the relationship between them in nursing students of Tehran University of Medical Sciences. The target population of this cross-sectional study was bachelor nursing students of Tehran University of Medical Sciences, as the largest and one of the most prestigious Iranian universities. For selecting samples, the convenience sampling method was used. Having no previous information about classes, the researcher selected the students from the courses held while the researcher was present for sampling at the faculty and studied all the students willing to participate in the study in selected classes. The questionnaire consisted of demographic information, Gambrill and Richey assertion inventory, and Beck's depression inventory. SPSS software, version 16, was used to analyze the data. ANOVA and independent samples t test were used for as appropriated. 55.6% of students indicated average and low levels of assertiveness and 38.7% were suffering from mild to severe depression. Pearson correlation test showed a significant inverse relationship (r=0.314 and Passertiveness and depression. There were significant relationships between depression and interest in the field of study (P=0.001) and between assertiveness and gender (P=0.035). There was an inverse significant relationship between depression and assertiveness among nursing students. We suggest a cohort study design that can determine the effect of these variables on each other completely.

Although stressful life events (SLEs) and depression are associated, we do not know if the intersection of race and gender modifies the magnitude of this link. Using a nationally representative sample of adults in the USA, we tested if the association between SLE and major depressive episode (MDE) depends on the intersection of race and gender. Data came from the National Survey of American Life (NSAL), 2003, a cross-sectional survey that enrolled 5899 adults including 5008 Blacks (African-Americans or Caribbean Blacks), and 891 Non-Hispanic Whites. Logistic regression was used for data analysis. Stressful life events (past 30 days) was the independent variable, 12-month MDE was the dependent variable, and age, educational level, marital status, employment, and region of country were controls. In the pooled sample, SLE was associated with MDE above and beyond all covariates, without the SLE × race interaction term being significant. Among men, the SLE × race interaction was significant, suggesting a stronger association between SLE and MDE among White men compared to Black men. Such interaction between SLE × race could not be found among women. The association between SLE and depression may be stronger for White men than Black men; however, this link does not differ between White and Black women. More research is needed to better understand the mechanism behind race by gender variation in the stress-depression link.

The goal of this study was to determine whether sleep moderates the associations between family-related stress and depressive symptoms and negative affect outcomes during adolescence. We combined traditional survey measures of stress and depressive symptoms with daily assessments of stress and negative affect to examine whether sleep differentially impacts the link between chronic and acute experiences of stress and affect. Participants were 316 adolescents from ethnically diverse backgrounds. Primary caregivers and adolescents reported on stressful family events during the past 12 and 3 months, respectively. Adolescents also reported on their daily experiences of family demands for 15 days and wore actigraph watches for the assessment of sleep during the first eight nights. Regression analyses revealed that more stressful family events were related to more depressive symptoms. This relation was stronger among adolescents with lower sleep efficiency. The same pattern emerged for the relation between daily family demands and negative affect aggregated across the 15 days. Daily-level analyses indicated that daily negative affect was related to daily family demands when sleep efficiency was higher than usual, but only among European American adolescents. These findings suggest that chronic experiences of lower sleep efficiency, but not sleep duration, may render adolescents more vulnerable to the negative effects of family stress on emotional adjustment. A more complex picture emerged for the role of prior night's sleep in the day-to-day variation in negative affect reactivity to family stress.

Dyslipidemia and obesity have been observed in persons with severe anxiety or depression, and in tricyclic antidepressant (TCA) users. This likely contributes to the higher risk of cardiovascular disease (CVD) in anxiety and depressive disorders. We aimed to elucidate whether biological stress systems or lifestyle factors underlie these associations. If so, they may be useful targets for CVD prevention and intervention. Within 2850 Netherlands Study of Depression and Anxiety (NESDA) participants, we evaluated the explaining impact of biological stress systems (i.e., the hypothalamic-pituitary-adrenal [HPA] axis, autonomic nervous system [ANS] and inflammation) and lifestyle factors (i.e., tobacco and alcohol use, and physical activity) on adverse associations of anxiety and depression severity and TCA use with high and low-density lipoprotein cholesterol, triglycerides, body mass index and waist circumference. Through linear regression analyses, percentual change (%Δ) in β was determined and considered significant when %Δ>10. The inflammatory marker C-reactive protein had the most consistent impact (explaining 14-53% of the associations of anxiety and depression severity and TCA use with lipid and obesity levels), followed by tobacco use (explaining 34-43% of the associations with lipids). The ANS mediated all associations with TCA use (explaining 32-61%). The HPA axis measures did not explain any of the associations. Increased dyslipidemia and (abdominal) obesity risk in patients with more severe anxiety disorders and depression may be partly explained by chronic low-grade inflammation and smoking. TCAs may increase metabolic risk through enhanced sympathetic and decreased parasympathetic ANS activity. That the HPA axis had no impact in our sample may reflect the possibility that the HPA axis only plays a role in acute stress situations rather than under basal conditions.

Increasing evidence has demonstrated that patients with depression have a higher risk of developing type 2 diabetes. Insulin resistance has been identified as the key mechanism linking depression and diabetes. The present study established a rat model of depression complicated by insulin resistance using a 12-week exposure to chronic mild stress (CMS) and investigated the therapeutic effects of curcumin. Sucrose intake tests were used to evaluate depressive-like behaviors, and oral glucose tolerance tests (OGTT) and intraperitoneal insulin tolerance tests (IPITT) were performed to evaluate insulin sensitivity. Serum parameters were detected using commercial kits. Real-time quantitative PCR was used to examine mRNA expression. CMS rats exhibited reduced sucrose consumption, increased serum glucose, insulin, triglyceride (TG), low density lipoprotein-cholesterol (LDL-C), non-esterified fatty acid (NEFA), glucagon, leptin, and corticosterone levels, as well as impaired insulin sensitivity. Curcumin upregulated the phosphorylation of insulin receptor substrate (IRS)-1 and protein kinase B (Akt) in the liver, enhanced insulin sensitivity, and reversed the metabolic abnormalities and depressive-like behaviors mentioned above. Moreover, curcumin increased the hepatic glycogen content by inhibiting glycogen synthase kinase (GSK)-3β and prevented gluconeogenesis by inhibiting phosphoenolpyruvate carboxykinase (PEPCK) and glucose 6-phosphatase (G6Pase). These results suggest that curcumin not only exerted antidepressant-like effects, but also reversed the insulin resistance and metabolic abnormalities induced by CMS. These data may provide evidence to support the potential use of curcumin against depression and/or metabolic disorders.

The aims of the current study were to examine the prevalence of potentially traumatic events (PTEs), posttraumatic stress disorder (PTSD; data available in males only), and depressive symptoms in a Puerto Rican sample of 678 adult caretakers (50% female) of twins participating in the Puerto Rican Infant Twin Study. The World Health Organization Composite International Diagnostic Interview version 3.0 (CIDI 3.0) was utilized to assess rates of PTEs, PTSD, and depression among male participants while an abbreviated version of the CIDI 3.0 and the Mood and Feelings Questionnaire were administered to females to assess PTEs and depressive symptoms. Significantly more males than females reported exposure to a PTE (76.6% vs. 44.2%, χ(2) = 64.44, p < 0.001). In males, endorsement of multiple PTEs was associated with increased level of PTSD symptomatology (β = 0.33, p < 0.001). With regard to depression, a similar dose-response relationship was found in both males and females, with depressive symptoms increasing as number of PTEs increased (βs = 0.15, 0.16, ps < 0.05). Exposure to an attack with a weapon was significantly associated with increased depression symptoms in both males and females (βs = 0.24, 0.20, ps < 0.01, respectively). These findings highlight the need for identification of putative risk and resilience factors among PTE-exposed individuals in Puerto Rico.

Depression is common in older people and its identification and treatment has been highlighted as one of the major challenges in an ageing world. Poor physical and cognitive health, bereavement, and prior depression are important risk factors for depression in elderly people. Attributional or cognitive style has been identified as a risk factor for depression in children, adolescents and younger adults but its relevance for depression and mood in elderly people has not been investigated in the context of other risk factors. Sixty-four older adults from an 'extra care' living scheme (aged 59-97) were recruited for a 6-week prospective study to examine the relationships between cognitive style and depressive symptoms. Regression analyses revealed that, when other risk factors were controlled for, cognitive style and its interaction with stress predicted changes in depressive symptoms, therefore partially replicating prior research. Cognitive-stress-vulnerability models also apply to elderly populations, but may be rather predictive of changes in depression when facing lower levels of stress. Copyright 2010 Elsevier Ltd.

Full Text Available Background: Smoking is prohibited in India at all the public places including hospital premises, but people with habit of smoking are not able to abide the rules strictly. Somehow, level of dependence and stress along with other psychological variables like anxiety and depression play key roles in smoking in the hospital premises. Methodology: Present study aimed to know the level of dependence and other psychological variables like depression, anxiety, and stress in the caregivers of patients of casualty and outpatients departments. Seventy five participants were recruited purposively from the hospital premises. The Fagerström Test for Nicotine Dependence and the Depression Anxiety Stress Scales (DASS- Hindi were administered. Result: Participants reported nicotine dependence was associated with psychological variables like mild to moderate level of depression, anxiety, and stress. Caregivers of casualty patients were having high level of stress than caregivers of outpatients. Conclusion: It can be concluded that psychological variables play a significant role in nicotine dependence.

Depression and anxiety have been associated with a range of symptoms that often overlap. Depression, Anxiety and Stress Scale-21 (DASS-21) is a single instrument to assess symptoms of depression, anxiety and stress. This study aimed to adapt and validate the DASS-21 for use in the Brazilian Portuguese language. The DASS-21 has been adapted following the translation-back translation methodology from English to Portuguese. 242 subjects completed the following assessments: the DASS-21, the Beck Depression Index (BDI), Beck Anxiety Index (BAI) and the Inventory of Stress Symptoms of Lipp (ISSL). The Kaiser-Meyer-Olkin (KMO) result was .949, indicating that the adequacy of the model was high. Cronbach's alpha was .92 for the depression, .90 for the stress, and .86 for the anxiety, indicating a good internal consistency for each subscale. The correlations between DASS scale and BDI scale, BAI scale and ISSL inventory were strong. The factorial analysis and distribution of factors among the subscales indicated that the structure of three distinct factors is adequate. Older subjects over 65 years of age were not largely represented in this sample. A study specific to this elderly population should be conducted. Another limitation of the study was education level. The impact of low education in its applicability should be considered. The findings support the validity of the Brazilian Portuguese version of the DASS-21 and add to the evidence of the DASS-21 quality and ability to assess emotional states separately, eliminating the use of different instruments to assess these states. © 2013 Published by Elsevier B.V.

Hijab or veiling is commonly practiced by Muslim women but remains controversial in the broader secular society. Some Western feminists argue that veiling is an oppressive behavior that negatively affects women by, for example, engendering depression. This article tests this hypothesis with a national sample of American Muslim women (N = 194). The results of the regression analysis did not support the hypothesis. Indeed, women who veiled more frequently reported lower, rather than higher, levels of depressive symptoms. In other words, wearing the hijab appears to be a protective factor in the area of depression. Given the prevalence of depression among women, the results have important implications for practice with Muslim women at both the micro and the macro levels. © 2017 National Association of Social Workers.

Previous research has focussed extensively on the distinction of HPA-axis functioning between patient groups and healthy volunteers, with relatively little emphasis on a direct comparison of patient groups. The current study's aim was to analyse differences in the cortisol stress response as a function of primary diagnosis of panic disorder (PD), post-traumatic stress disorder (PTSD), and major depressive disorder (MDD). A total of n=30 PD (mean age±SD: 36.07±12.56), n=23 PTSD (41.22±10.17), n=18 MDD patients (39.00±14.93) and n=47 healthy control (HC) individuals (35.51±13.15) participated in this study. All the study participants were female. The Trier Social Stress Test (TSST) was used for reliable laboratory stress induction. Blood sampling accompanied the TSST for cortisol and ACTH assessment. Panic-related, PTSD-specific questionnaires and the Beck Depression Inventory II were handed out for the characterisation of the study groups. Repeated measure ANCOVAs were conducted to test for main effects of time or group and for interaction effects. Regression analyses were conducted to take comorbid depression into account. 26.7% of the PD patients, 43.5% of the PTSD patients, 72.2% of the MDD patients and 80.6% of the HC participants showed a cortisol stress response upon the TSST. ANCOVA revealed a cortisol hypo-responsiveness both in PD and PTSD patients, while no significant group differences were seen in the ACTH concentrations. Additional analyses showed no impact of comorbid depressiveness on the cortisol stress response. MDD patients did not differ in the hormonal stress response neither compared to the HC participants nor to the PD and PTSD patients. Our main findings provide evidence of a dissociation between the cortisol and ACTH concentrations in response to the TSST in PTSD and in PD patients, independent of comorbid depression. Our results further support overall research findings of a cortisol hypo-responsiveness in PD patients. A hypo

The fetal brain is highly susceptible to stress in late pregnancy, with lifelong effects of stress on physiology and behavior. The aim of this study was to determine the physiological and behavioral effects of prenatal stress during the prepubertal period of female and male rats. We subjected pregnant Sprague-Dawley rats to a restraint stress protocol from gestational day 14 until 21, a critical period for fetal brain susceptibility to stress effects. Male and female offspring were subsequently assessed at postnatal day 24 for anxiety- and depressive-like behaviors, and spontaneous social interaction. We also assessed maternal behaviors and two stress markers: basal vs. acute-evoked stress levels of serum corticosterone and body weight gain. Prenatal stress did not affect the maternal behavior, while both female and male offspring had higher body weight gain. On the other hand, lower levels of corticosterone after acute stress stimulation as well as anxiety- and depressive-like behaviors were only evident in stressed males compared to control males. These results suggest that prenatal stress induced sex-specific effects on the hypothalamus-pituitary-adrenal (HPA) axis activity and on behavior during prepuberty. The HPA axis of prenatally stressed male rats was less active compared to control males, as well as they were more anxious and experienced depressive-like behaviors. Our results can be useful to study the neurobiological basis of childhood depression at a pre-clinical level. This article is protected by copyright. All rights reserved.

Corticotropin-releasing hormone (CRH) plays a central role in the regulation of the hypothalamic-pituitary-adrenal (HPA)-axis, i.e., the final common pathway in the stress response. The action of CRH on ACTH release is strongly potentiated by vasopressin, that is co-produced in increasing amounts when the hypothalamic paraventricular neurons are chronically activated. Whereas vasopressin stimulates ACTH release in humans, oxytocin inhibits it. ACTH release results in the release of corticosteroids from the adrenal that, subsequently, through mineralocorticoid and glucocorticoid receptors, exert negative feedback on, among other things, the hippocampus, the pituitary and the hypothalamus. The most important glucocorticoid in humans is cortisol, present in higher levels in women than in men. During aging, the activation of the CRH neurons is modest compared to the extra activation observed in Alzheimer's disease (AD) and the even stronger increase in major depression. The HPA-axis is hyperactive in depression, due to genetic factors or due to aversive stimuli that may occur during early development or adult life. At least five interacting hypothalamic peptidergic systems are involved in the symptoms of major depression. Increased production of vasopressin in depression does not only occur in neurons that colocalize CRH, but also in neurons of the supraoptic nucleus (SON), which may lead to increased plasma levels of vasopressin, that have been related to an enhanced suicide risk. The increased activity of oxytocin neurons in the paraventricular nucleus (PVN) may be related to the eating disorders in depression. The suprachiasmatic nucleus (SCN), i.e., the biological clock of the brain, shows lower vasopressin production and a smaller circadian amplitude in depression, which may explain the sleeping problems in this disorder and may contribute to the strong CRH activation. The hypothalamo-pituitary thyroid (HPT)-axis is inhibited in depression. These hypothalamic

This research identifies stressors that correlate with depression, focusing on acculturation, among female Korean immigrants in California. Telephone interviews were conducted with female adults of Korean descent (N = 592) from a probability sample from 2006 to 2007. Sixty-five percent of attempted interviews were completed, of which over 90% were conducted in Korean. Analyses include descriptive reports, bivariate correlations, and structural equation modeling. Findings suggest that acculturation did not have a direct impact on depression and was not associated with social support. However, acculturation was associated with reduced immigrant stress which, in turn, was related to decreased levels of depression. Immigrant stress and social support were the principal direct influences on depression, mediating the effect for most other predictors. Stressful experiences associated with immigration may induce depressive feelings. Interventions should facilitate acculturation thereby reducing immigrant stress and expand peer networks to increase social support to assuage depression.

This article describes the efficacy of a guided imagery intervention for decreasing depression, anxiety, and stress and increasing comfort in psychiatric inpatients with depressive disorders. A quasi-experimental design sampled 60 short-term hospitalized depressive patients selected consecutively. The experimental group listened to a guided imagery compact disk once a day for 10 days. The Psychiatric Inpatients Comfort Scale and the Depression, Anxiety, and Stress Scales (DASS-21) were self-administered at two time points: prior to the intervention (T1) and 10 days later (T2). Comfort and DASS-21 were also assessed in the usual care group at T1 and T2. Repeated measures revealed that the treatment group had significantly improved comfort and decreased depression, anxiety, and stress over time.

Depressed individuals often refuse or withdraw from help, a phenomenon termed help-negation, which is a risk factor for poor outcomes. Most previous research has investigated psychosocial factors including stigma as causes of low help-seeking intentions for depression, however these do not adequately explain the problem. We hypothesised that because help-negation worsens with symptom severity, it might be linked to important biological changes associated with depression itself. We investigated the relative contributions of cortisol, a stress hormone linked to depression, and oxytocin, a hormone which mediates social behaviours, alongside psychosocial factors, to help-seeking intentions among depressed and non-depressed individuals. Morning plasma cortisol and oxytocin levels, psychopathology, suicidal ideation, help-seeking intentions from informal sources including family and friends, and formal sources including health professionals, and perceived social support were quantified in 63 adults meeting DSM-5 criteria for major depressive disorder (MDD) who were not receiving any treatment, and 60 healthy controls. Between-group analyses of variance, correlations, and hierarchical multiple regressions were employed. Help-seeking intentions were lower in depressed than healthy participants, negatively correlated to cortisol and positively correlated to oxytocin. Cortisol negatively, and oxytocin positively, predicted help-seeking intentions from informal but not formal sources, after controlling for psychopathology and psychosocial factors. Neuroendocrine changes associated with depression may contribute to low help-seeking from friends and family, which may have implications for interpersonal support and outcomes. Research and clinical approaches which incorporate biological as well as psychosocial factors may allow for more targeted and effective early interventions to address lack of help-seeking and depression progression.

As a regulator of food intake, ghrelin also plays a key role in mood disorders. Previous studies reported that acute ghrelin administration defends against depressive symptoms of chronic stress. However, the effects of long-term ghrelin on rodents under chronic stress hasn't been revealed. In this study, we found chronic peripheral administration of ghrelin (5nmol/kg/day for 2 weeks, i.p.) could alleviate anxiety- and depression-like behaviors induced by chronic unpredictable mild stress (CUMS). The depression-like behaviors were assessed by the forced swimming test (FST), and anxiety-like behaviors were assessed by the open field test (OFT) and the elevated plus maze test (EPM). Meanwhile, we observed that peripheral acylated ghrelin, together with gastral and hippocampal ghrelin prepropeptide mRNA level, were significantly up-regulated in CUMS mice. Besides, the increased protein level of growth hormone secretagogue receptor (GHSR) in hippocampus were also detected. These results suggested that the endogenous ghrelin/GHSR pathway activated by CUMS plays a role in homeostasis. Further results showed that central treatment of ghrelin (10μg/rat/day for 2 weeks, i.c.v.) or GHRP-6 (the agonist of GHSR, 10μg/rat/day for 2 weeks, i.c.v.) significantly alleviated the depression-like behaviors induced by CUMS in FST and sucrose preference test (SPT). Based on these results, we concluded that central GHSR is involved in the antidepressant-like effect of exogenous ghrelin treatment, and ghrelin/GHSR may have the inherent neuromodulatory properties against depressive symptoms.

Several classic studies have concluded that the accuracy of identifying uncontrollable situations depends heavily on depressive mood. Nondepressed participants tend to exhibit an optimistic illusion of control, whereas depressed participants tend to better detect a lack of control. Recently, we suggested that the different activity levels (measured as the probability of responding during a contingency learning task) exhibited by depressed and nondepressed individuals is partly responsible for this effect. The two studies presented in this paper provide further support for this mediational hypothesis, in which mood is the distal cause of the illusion of control operating through activity level, the proximal cause. In Study 1, the probability of responding, P(R), was found to be a mediator variable between the depressive symptoms and the judgments of control. In Study 2, we intervened directly on the mediator variable: The P(R) for both depressed and nondepressed participants was manipulated through instructions. Our results confirm that P(R) manipulation produced differences in the participants' perceptions of uncontrollability. Importantly, the intervention on the mediator variable cancelled the effect of the distal cause; the participants' judgments of control were no longer mood dependent when the P(R) was manipulated. This result supports the hypothesis that the so-called depressive realism effect is actually mediated by the probability of responding.

Chronic exposure to stressful environment is a key risk factor contributing to the development of depression. However, the mechanisms involved in this process are still unclear. Brain-derived neurotropic factor (BDNF) has long been investigated for its positive role in regulation of mood, although the role of its precursor, proBDNF, in regulation of mood is not known. In this study, using an unpredictable chronic mild stress (UCMS) paradigm we found that the protein levels of proBDNF were increased in the neocortex and hippocampus of stressed mice and this UCMS-induced upregulation of proBDNF was abolished by chronic administration of fluoxetine. We then established a rat model of UCMS and found that the expression of proBDNF/p75 NTR /sortilin was upregulated, whereas the expression of mature BDNF and TrkB was downregulated in both neocortex and hippocampus of chronically stressed rats. Finally, we found that the injection of anti-proBDNF antibody via intracerebroventricular (i.c.v.) and intraperitoneal (i.p.) approaches into the UCMS rats significantly reversed the stress-induced depression-like behavior and restored the exploratory activity and spine growth. Although intramuscular injection of AAV-proBDNF did not exacerbate the UCMS-elicited rat mood-related behavioral or pathological abnormalities, i.c.v. injection of AAV-proBDNF increased the depression-like behavior in naive rats. Our findings suggest that proBDNF plays a role in the development of chronic stress-induced mood disturbances in rodents. Central (i.c.v.) or peripheral (i.p.) inhibition of proBDNF by injecting specific anti-proBDNF antibodies may provide a novel therapeutic approach for the treatment of stress-related mood disorders.

Developmental transitions are experienced throughout the life course and necessitate adapting to consequential and unpredictable changes that can undermine health. Our six-month study (n = 239) explored whether selective secondary control striving (motivation-focused thinking) protects against the elevated levels of stress and depressive symptoms increasingly common to young adults navigating the challenging school-to-university transition. Path analyses supplemented with tests of moderated mediation revealed that, for young adults who face challenging obstacles to goal attainment, selective secondary control indirectly reduced long-term stress-related physical and depressive symptoms through selective primary control and previously unexamined measures of discrete emotions. Results advance the existing literature by demonstrating that (a) selective secondary control has health benefits for vulnerable young adults and (b) these benefits are largely a consequence of the process variables proposed in Heckhausen et al.'s (2010) theory.

Anxiety and depression following traumatic brain injury (TBI) are associated with poorer outcomes. A brief self-report questionnaire would assist in identifying those at risk, however validity of such measures is complicated by confounding symptoms of the injury. This study investigated the validity of the Depression Anxiety Stress Scales (DASS) and Hospital Anxiety and Depression Scale (HADS), in screening for clinical diagnoses of anxiety and mood disorders following TBI. One hundred and twenty-three participants with mild to severe TBI were interviewed using the SCID (Axis I) and completed the DASS and HADS. The DASS, DASS21 and HADS scales demonstrated validity compared with SCID diagnoses of anxiety and mood disorders as measured by Area Under ROC Curve, sensitivity and specificity. Validity of the DASS depression scale benefited from items reflecting symptoms of devaluation of life, self-deprecation, and hopelessness that are not present on the HADS. Validity of the HADS anxiety scale benefited from items reflecting symptoms of tension and worry that are measured separately for the DASS on the stress scale. Participants were predominantly drawn from a rehabilitation centre which may limit the extent to which results can be generalized. Scores for the DASS21 were derived from the DASS rather than being administered separately. The DASS, DASS21 and HADS demonstrated validity as screening measures of anxiety and mood disorders in this TBI sample. The findings support use of these self-report questionnaires for individuals with TBI to identify those who should be referred for clinical diagnostic follow-up. © 2013 Elsevier B.V.

Understanding how persistent interpersonal difficulties distinctly affect the course of major depressive disorder (MDD) during emerging adulthood is critical, given that early experiences impact future coping resources and functioning. Research on stress and MDD has mostly concentrated on stressful life events, while chronic stress largely has not been explored. The present study examined interpersonal (intimate relationship, close friendships, social life, family relationships) and noninterpersonal (academic, work, financial, personal health, and family members' health) domains of chronic stress as time-varying predictors of depressive recurrence in emerging adults. Baseline assessments identified previously depressed emerging adults (N = 119), who subsequently completed 6-month, 12-month and 18-month follow-up interviews to determine chronic stress experiences and onset of new major depressive episodes. Survival analyses indicated that time-varying total chronic stress and chronic interpersonal stress predicted higher risk for depression recurrence; however, chronic noninterpersonal stress was not associated with recurrence. Intimate relationship stress, close friendship stress, family relationship stress, personal health, and family members' health independently predicted MDD recurrence, over and above well-established depression risk factors of dysfunctional cognitions and personality disorder symptoms. Evidence that interpersonal stress could have substantial impact on course of depression is consistent with theories of emerging adulthood, a time when young people are individuating from the family and experiencing significant social transition.

Full Text Available OBJECTIVE: To evaluate the temporal and case-controlled correlations of anxiety, depression and stress with hyperemesis gravidarum. STUDY DESIGN: We performed a longitudinal cohort study of women with hyperemesis gravidarum using the Depression, Anxiety and Stress Scale (DASS-21 to evaluate psychological distress at hospitalization and in the third trimester of pregnancy (from 28 weeks gestation. Third pregnancy trimester controls were recruited from routine antenatal clinic attendees who were matched to gestational age at the second DASS-21 assessment in the HG cohort. RESULTS: The prevalences of nausea and vomiting, depression, anxiety and stress caseness in newly hospitalised hyperemesis gravidarum women were 100% and 100%, 19%, 69% and 21% which by the third trimester had fallen to 15.7% and 9.9%, 4%, 19% and 3% and in third trimester controls were 15.9% and 14.2%, 14%, 61% and 20% respectively. Within the hyperemesis gravidarum cohort, nausea, vomiting depression, anxiety and stress reduced significantly by an absolute 84.3% (95% CI 76.2%-89.8%, 90.1% (82.8%-94.2%, 14.9% (7.2%-23.0%, 49.6% (38.6%-58.7% and 18.2% (10.4%-26.4% respectively between hospitalization for hyperemesis gravidarum and at the third trimester. In the third trimester, when comparing the hyperemesis gravidarum cohort to controls, the risk of nausea or vomiting was similar but depression, anxiety and stress were significantly lower: adjusted odds ratio AOR 0.10 (95% CI 0.03-0.5, 0.11 (0.05-0.23 and 0.08 (0.02-0.33 respectively. CONCLUSION: Our study revealed a reassuring pattern of a strong rebound from depression, anxiety and stress in women with hyperemesis gravidarum such that by the third pregnancy trimester the level of psychological distress was even lower than in controls. This observation imply that much of the psychological distress in acute hyperemesis gravidarum is self-limiting and probably in the causal pathway of hyperemesis gravidarum. Care in women with

Posttraumatic stress disorder (PTSD) and depression co-occur frequently following the experience of potentially traumatizing events (PTE; Morina et al., 2013). A person-centered approach to discern heterogeneous patterns of such co-occurring symptoms is recommended (Galatzer-Levy and Bryant, 2013). We assessed heterogeneity in PTSD and depression symptomatology; and subsequently assessed relations between class membership with psychopathology constructs (alcohol use, distress tolerance, dissociative experiences). The sample consisted of 268 university students who had experienced a PTE and susequently endorsed clinical levels of PTSD or depression severity. Latent profile analyses (LPA) was used to identify the best-fitting class solution accouring to recommended fit indices (Nylund et al., 2007a); and the effects of covariates was analyzed using a 3-step approach (Vermunt, 2010). Results of the LPA indicated an optimal 3-class solutions: high severity (Class 2), lower PTSD-higher depression (Class 1), and higher PTSD-lower depression (Class 3). Covariates of distress tolerance, and different kinds of dissociative experiences differentiated the latent classes. Use of self-report measure could lead to response biases; and the specific nature of the sample limits generalizability of results. We found evidence for a depressive subtype of PTSD differentiated from other classes in terms of lower distress tolerance and greater dissociative experiences. Thus, transdiagnostic treatment protocols may be most beneficial for these latent class members. Further, the distinctiveness of PTSD and depression at comparatively lower levels of PTSD severity was supported (mainly in terms of distress tolerance abilities); hence supporting the current classification system placement of these disorders.

Full Text Available Introduction: Psychiatric disorders such as depression, stress, and anxiety are factors that affect the quality of life, suicide and many physical problems, and socioeconomic in elders. Considering the importance of the issue and increasing the number of elderly people in this County, researchers decided to investigate the levels of stress, anxiety, and depression in the elderly health centers of Khoy, Iran. Methods: This cross-sectional study was done on 383 elderly people referred to health centers in Khoy County. A random cluster sampling was used in this study where each health care is considered as a cluster. The Depression, Anxiety, Stress Scale 21 (DASS-21 standard questionnaire was used for data collection. The SPSS software was used for all computations. Data were analyzed using descriptive statistic, t-test, and one-way ANOVA. P < 0.050 was determined to be significant. Results: The results of this study showed that 1.3% of the elderly people suffer from very severe stress, 1.3% from severe depression, and 3.1% from severe anxiety. Likewise, the comparison between anxiety, stress, and depression disorders with demographic variables showed that there is a significant association between these disorders and sex, education, marital status, medical condition, as well as their housing conditions (P < 0.050. Conclusion: The results of this study indicated anxiety disorders, depression, and stress prevail among the elderly. In addition, some factors such as education, housing, medical condition, and marital status had significant effects on anxiety disorders, depression, and stress. Therefore, more attention is deserved in these aspects. Moreover, appropriate measures need to be taken to improve the mental health of elderly people.
Full Text Available This paper presented the Turkish version of the Depression Anxiety Stress Scale-21 (DASS-21 in community and clinical samples, examined its psychometric properties. Construct validity and concurrent validity were conducted in validity studies. Depression Anxiety Stress Scale-42 (DASS-42 was used for concurrent validity. In reliability analysis, the instruments internal consistency and re-test reliability were studied. Results of explanatory factor analyses demonstrated that 21 items yielded three-factors. Results of confirmatory factor analyses for three-dimensional model showed that acceptable fit index values in community sample and perfect fit index values in clinical sample. Factor loadings ranged from .42 to .72. In the concurrent validity, significant positive relationships were found between DASS-42 and DASS-21. Cronbach alpha internal consistency coefficient was found as α= .87 for depression sub-scale, α= .85 for anxiety sub-scale and α= .81 for stress sub-scale in clinical sample. Moreover, test-retest reliability coefficient was obtained as r=.68 for depression sub-scale, r=.66 for anxiety sub-scale and r=.61 for stress sub-scale in community sample, and corrected item-total correlations ranged from .43 to .77 in clinical sample. In second study, DASS-21 discriminated the patients (depression mean score=10.83; anxiety mean score=10.39; stress mean score=11.85 from the healthy subjects (depression mean score=5.88; anxiety mean score=5.37; stress mean score=7.90 well (U=5310.50; 4748.50; 5562.50, p=0.00. According to psychometric properties, DASS-21 is a reliable and valid instrument in the assessment of depression, anxiety, stress levels. [JCBPR 2018; 7(1.000: 19-30

Nursing students often experience depression, anxiety, stress and decreased mindfulness which may decrease their patient care effectiveness. Mindfulness-based stress reduction (MBSR) effectively reduced depression, anxiety and stress, and increased mindfulness in previous research with other populations, but there is sparse evidence regarding its effectiveness for nursing students in Korea. To examine the effects of MBSR on depression, anxiety, stress and mindfulness in Korean nursing students. A randomized controlled trial. Fifty (50) nursing students at KN University College of Nursing in South Korea were randomly assigned to two groups. Data from 44 students, MBSR (n=21) and a wait list (WL) control (n=23) were analyzed. The MBSR group practiced mindfulness meditation for 2 h every week for 8 weeks. The WL group did not receive MBSR intervention. Standardized self-administered questionnaires of depression, anxiety, stress and mindfulness were administered at the baseline prior to the MBSR program and at completion (at 8 weeks). Compared with WL participants, MBSR participants reported significantly greater decreases in depression, anxiety and stress, and greater increase in mindfulness. A program of MBSR was effective when it was used with nursing students in reducing measures of depression, anxiety and stress, and increasing their mindful awareness. MBSR shows promise for use with nursing students to address their experience of mild depression, anxiety and stress, and to increase mindfulness in academic and clinical work, warranting further study.

Two of the problems that currently affect a large proportion of university students are high levels of anxiety and stress experienced in different situations, which are particularly high during the first years of their degree and during exam periods. The present study aims to investigate whether mindfulness training can bring about significant changes in the manifestations of depression, anxiety, and stress of students when compared to another group undergoing a physical activity program and a control group. The sample consisted of 125 students from the Bachelor of Education Program. The measuring instrument used was the Abbreviated Scale of Depression, Anxiety and Stress (DASS-21). The results indicate that the effects of reducing the identified variables were higher for the mindfulness group than for the physical education group and for the control group F(2) = 5.91, p = .004, η2 = .106. The total scores for all variables related to the mindfulness group decreased significantly, including an important stress reduction t(29) = 2.95, p = .006, d = .667. Mindfulness exercises and some individual relaxing exercises involving Physical Education could help to reduce manifestations of stress and anxiety caused by exams in students.
Full Text Available A decrease in the quality of sleep is believed to cause anxiety and worsen depression. Comparisons of salivary melatonin levels with different factors including quality of sleep, state and trait anxieties, and depression, were conducted to examine whether there is a relationship between melatonin, presumably associated with sleep, and psychological stress. The saliva of healthy young females was collected during the daytime and before they went to bed at night (when they were awake and resting in a sitting position, and salivary melatonin levels were measured. The quality of sleep was scored using the Pittsburgh Sleep Quality Index (PSQI–-a questionnaire method. State and trait anxieties, and depression were scored using other questionnaire methods: the State-Trait Anxiety Inventory (STAI and Self-Rating Depression Scale (SDS, respectively. The following findings were obtained: (1 Salivary melatonin levels measured during the daytime and before going to bed were higher in females with a high depression score, compared to those with a low score, and there was a correlation between the depression scores and salivary melatonin levels measured at night; and (2 salivary melatonin levels measured before going to bed at night (in a sitting position were higher in females with a high state anxiety score, suggesting a correlation between state anxiety scores and salivary melatonin levels during the night. Both depression and a sense of anxiety are forms of psychological stress. Therefore, it is assumed that, when a person is under psychological stress, the action of melatonin as a ligand on its receptor is reduced. Meaning psychological stress may induce oxidative stress in the body. On the other hand, no correlation was noted between the quality of sleep and salivary melatonin levels during the night, presumably because saliva was collected when the subjects were awake and sitting, rather than sleeping.

This study examined cross-sectional and longitudinal patterns of parenting stress, adult anxiety, and depression in mothers of children with profound or severe visual impairment (PVI or SVI) at 1 year and 2 years of age. Mothers of a national longitudinal cohort (OPTIMUM Project) of infants with congenital disorders of the peripheral visual system and PVI (light perception at best) or SVI (basic 'form' vision of non-light reflecting objects) participated. Infant age at baseline (T 1 ) was 8 to 16 months. Mothers completed the Parenting Stress Index - Short Form and the Hospital Anxiety and Depression Scale at T 1 (n=79) and at follow-up 12 months later (T 2 ) (n=73). Mothers of the total group had higher parenting stress levels (34.6% in clinical range) than community normative data at T 1 (p=0.017). Mothers of infants in the PVI subgroup had elevated stress at T 1 (p=0.014) and T 2 (p=0.009). The PVI subgroup was also elevated in the Difficult Child subscale at T 2 (p=0.001). Within-sample differences in parenting stress between the visual impairment subgroups were found at T 2 only: the PVI subgroup scored higher than the SVI subgroup (p=0.029). Adult anxiety and depression in the total group were not elevated compared with community normative data at T 1 and T 2 ; however, higher parenting stress was related to raised adult anxiety and depression levels at T 1 and T 2 (p=0.001). Regression analysis found parenting stress and lower child vision level (T 1 ) predicted parenting stress (T 2 ) (p=0.001; 42% variance). Mothers of 1-year-old infants with visual impairment showed raised risk for parenting stress, which continued to be elevated for children with PVI and those perceived as 'difficult' at 2 years. This was also a psychological risk, with greater adult anxiety and depression in those mothers with raised parenting stress. The clinical significance is that identification of parenting stress and targeted parenting, and behavioural support of the child in

This study aimed to assess possible interactive effects of coping styles and psychological stress on depression and anxiety symptoms in Chinese patients with Type 2 diabetes. Three hundred and four patients with Type 2 diabetes underwent a face-to-face interview by trained research staff according to a standardized questionnaire including information on socio-demographic characteristics, psychological stress, coping styles and anxiety and depressive symptoms. The interactive effects of coping styles and psychological stress on depression and anxiety symptoms were assessed by hierarchical multiple regression analyses. There were significant associations of the four domains of psychological stress with anxiety and depressive symptoms, except for the relationship between 'reduced economic condition' and depressive symptoms. 'Negative coping style' significantly increased the level of both anxiety and depressive symptoms; whereas, 'active coping style' and 'avoidant coping style' decreased the risk of depressive symptoms. The interactions of 'negative coping style' with 'worrying about decline in body/physical function' and 'reduced economic condition' significantly increased the risk of anxiety and depressive symptoms, and the interaction of 'social/family crisis caused by the disease' with 'avoidance coping style' and 'worrying about decline in body/physical function' with 'active coping style' significantly decreased the risk of depressive symptoms. The results of this study suggest that certain coping styles might moderate the association of psychological stress with anxiety and depressive symptoms in Chinese patients with Type 2 diabetes.

To identify the effects of foot reflexology massage on fatigue, stress and depression of postpartum women. A nonequivalent control group pre-post design was used. A total of 70 women in a postpartum care center were recruited and were assigned to the experimental group (35) or control group (35). Foot reflexology massage was provided to the experimental group once a day for three days. Data were collected before and after the intervention program which was carried out from December, 2013 to February, 2014. Data were analyzed using Chi-square test, Fisher's exact test, and t-test. The level of fatigue in the experimental group was significantly lower than the control group (t=-2.74, p=.008). The level of cortisol in the urine of women in the experimental group was significantly lower than the control group (t=-2.19, p=.032). The level of depression in the experimental group was significantly lower than the control group (t=-3.00, p=.004). The results show that the foot reflexology massage is an effective nursing intervention to relieve fatigue, stress, and depression for postpartum women.

Full Text Available Abstract Background Mental health problems in young people are an important public health issue. Students leaving their hometown and family at a young age to pursue better educational opportunities overseas are confronted with life adjustment stress, which in turn affects their mental health and academic performance. This study aimed to examine the relationships among stress, coping strategies, and depressive symptoms using the stress coping framework in overseas Chinese university preparatory students in Taiwan. Methods A cross-sectional study was conducted at an overseas Chinese university preparatory institute in Taiwan. Of enrolled overseas Chinese university preparatory students at 2009, 756 completed a structured questionnaire measuring stress, strategies for coping with it, and the Center for Epidemiologic Studies Depression Scale. Results High levels of stress significantly predicted the adoption of active, problem-focused coping strategies (R2 = 0.13, p R2 = 0.24, p z = 8.06, p Conclusion Our study results suggested that stress is associated with coping strategies and depressive symptoms and passive strategies mediate the relation between stress and depressive symptoms in overseas Chinese university preparatory students.

To determine the prevalence of symptoms of depression, anxiety and stress among secondary school girls. A cross- sectional study was carried out on secondary school girls in Abha city, Aseer Region, Saudi Arabia, using the Arabic version of the Depression, Anxiety, and Stress Scale (DASS-42). Of 545 female students recruited in this study, 73.4% had the symptoms of at least one of the three studied disorders; 50.1% had at least two disorders. The prevalence of symptoms of depression, anxiety and stress was 41.5 %, 66.2% and 52.5% respectively. The majority of symptoms were mild to moderate in severity. The scores for depression, anxiety, and stress were positively and significantly correlated. No significant association was found between the girls' sociodemographic characteristics and the scores of the three studied disorders. One of the most important aspects of a primary care physician's care of females is to screen for and treat common mental disorders.

Over the past four years, the Franciscan University Counseling Center has reported a 231% increase in yearly visits, as well as a 173% increase in total yearly clients. This trend has been observed at many universities as mental health issues pose significant problems for many college students. The objective of this study was to investigate potential correlates of depression, anxiety, and stress in a sample of college students. The final analyzed sample consisted of 374 undergraduate students between the ages of 18 and 24 attending Franciscan University, Steubenville, Ohio. Subjects completed a survey consisting of demographic questions, a section instructing participants to rate the level of concern associated with challenges pertinent to daily life (e.g. academics, family, sleep), and the 21 question version of the Depression Anxiety Stress Scale (DASS21). The results indicated that the top three concerns were academic performance, pressure to succeed, and post-graduation plans. Demographically, the most stressed, anxious, and depressed students were transfers, upperclassmen, and those living off-campus. With the propensity for mental health issues to hinder the success of college students, it is vital that colleges continually evaluate the mental health of their students and tailor treatment programs to specifically target their needs.

The Depression Anxiety Stress Scale (DASS) was designed to efficiently measure the core symptoms of anxiety and depression and has demonstrated positive psychometric properties in adult samples of anxiety and depression patients and student samples. Despite these findings, the psychometric properties of the DASS remain untested in older adults, for whom the identification of efficient measures of these constructs is especially important.

An increasing number of women from other countries, mostly Mainland China and Southeast Asia, are marrying Taiwanese husbands and settling in Taiwan. Immigration, marriage abroad, and pregnancy may be stressful and adversely affect maternal health. Relatively little research has compared the life stress and depressive symptoms of pregnant women of different ethnic groups living in nonmetropolitan areas in Taiwan. This study investigates the levels of life stress and depressive symptoms in pregnant Taiwanese women and Vietnamese "foreign brides" currently living in southern Taiwan. Eligible women in their last trimester of pregnancy who attended their local antenatal clinic were recruited for the study. Participants completed standardized measures, including the Difficult Life Circumstances Scale, Social Support APGAR Scale, and Edinburgh Postnatal Depression Scale. Two hundred thirty-six Taiwanese women and 44 Vietnamese women participated. Major life difficulties for both groups of women were related to their marital relationship, housing, or health problems. Taiwanese participants reported perceiving financial strain more often than their Vietnamese peers, whereas Vietnamese participants reported perceiving greater concerns regarding their children's development and about recent physical abuse than their Taiwanese peers. Furthermore, the Vietnamese participants reported less social support and higher rates of antenatal depression than Taiwanese participants. Clinical nurses and midwives should be sensitive to the particular difficulties and insufficient social support faced by pregnant women from different backgrounds in Taiwan. Women from foreign countries or those under unique challenging circumstances may face a particular risk of adverse outcomes. Identifying stresses informs the development of effective nursing interventions and support activities for new mothers and their families.

Full Text Available OBJECTIVE: Epilepsy is characterized by sudden seizures and loss of control in patients; it leads to constantly be under stress. Psychiatric disorders, particularly depressive disorders are more frequent in patients with epilepsy than in the whole of society. In this study; we aimed to compare depression,anxiety and desperation levels between epileptic patients and healthy ones. METHODS: 34 patients and 34 healthy controls were enrolled to the study. Demographic features of all subjects were also recorded. Neurologic examination, Electroencephalography (EEG and cranial magnetic resonance imaging(MRI of patients were also evaluated. State-Trait Anxety Inventory (STAI is for anxiety, Beck Depression Inventory (BDE is for depression, Beck Hopelessness Scale (BUO is for hopelessness were evaluated. RESULTS: Epileptic patients were with mean age of 24.56 ± 8.49, healthy subjects were with the mean age 27.44 ± 5.66 years. 13 of patients were female(38.2% and 21 patients were male(%38.2 in all groups.There was no significant difference about demographic features(p>0.05. When continuous and instant anxiety levels of epileptic and healthy groups were compared, no significant difference was observed between instant anxiety levels(p> 0.05; but there was difference between continuous anxiety levels (p <0.05. Also, hopelessness and depression levels were similar between groups (p<0.05. CONCLUSION: The results of the study showed that depression, anxiety and hopelessness levels were higher in epileptic patients when compared to healthy people. In addition, patients with seizure control with less drug use will reduce the level of trait anxiety was concluded.

Older farmers experience a high rate of suicide, and depression is closely aligned with suicide among agricultural workers. Depressive symptoms may be influenced by work patterns, work satisfaction, stress, and health status. In addition, members of a couple may affect each other's depressive symptoms. The purpose was to determine whether depressive symptoms score is predicted by hours worked on the farm, satisfaction with work, number of health conditions, perceived stress, and demographics in a sample of older farm couples, and to assess the degree of influence on depressive symptoms spouses have on each other. A total of 494 couples participated in the initial interview for a longitudinal study of farmers aged 50 and above. Data from husbands and wives were used together in a multilevel, dyad-based regression model to determine predictors of depressive symptoms. Men's depressive symptoms scores were predicted by their own number of health conditions and stress and by their wives' stress and health conditions. Women's depressive symptoms scores were predicted by their own work satisfaction, stress, and number of health conditions and their husbands' time spent working on the farm and stress. Stress management may be particularly important in older farm couples, since perceived duress of 1 member of the dyad impacts both. Work factors and health conditions also affect depressive symptoms in older rural couples, but these may be less easily modified. © 2013 National Rural Health Association.

This study investigated the mediating roles of sleep and depression on the relationships between stress, fat intake, and fruit and vegetable intake among low-income overweight and obese pregnant women by trimesters. Participants (N = 213) completed a self-administered survey including stress (exogenous variable), depression, sleep (mediators), fat intake, and fruit and vegetable intake (endogenous variables). Path analysis was performed to compare mediation effects among pregnant women in each trimester. Consistently across three trimesters, stress was related to depression but not sleep duration, night time sleep disturbance, sleep quality, sleep latency or fat intake. Sleep duration was not associated with depression. Depending on trimester, night time sleep disturbance, sleep quality, and sleep latency were related to depression; night time sleep disturbance and depression affected fat intake; stress influenced fruit and vegetable intake. Sleep duration, sleep disturbance, sleep quality, sleep latency and depression did not mediate the relationships between stress, fat intake, and fruit and vegetable intake in the second and third trimesters. However, depression mediated the relationship between stress and fat intake in the first trimester. Stress management interventions may help low-income overweight and obese pregnant women decrease depressive symptoms and therefore contribute to overall nutritional health.
Full Text Available Introduction: Bullying is a form of low-level violence in the school environment that if unnoticed to become dangerous forms of violence occurs. The aim of this study was examining the relationship between anxiety, stress and depression and female adolescents' suicidal thoughts with the meditating role of the victim of bullying. Materials and Methods: This study is descriptive and has used the correlation method. For this purpose in the academic year 2016-2017, 300 students of high school girl students (seventh and eighth grade of public schools of Pakdasht city were selected by random cluster sampling method and they filled in the suicidal thoughts, anxiety, stress, depression and victim of bullying questionnaire. For data analysis, Pearson’s correlation method and structural equation modeling were used by using SPSS-19 and LISRELV8.80 software. Results: Pearson’s correlational results showed that there is a positive and meaningful relation between anxiety, stress, depression and victim of bullying with suicidal thoughts (P≤0.01. Also the victim of bullying variable has a meditating role in relation among research variable and all of the direct and indirect effects of anxiety, stress, depression and victim of bullying on suicidal thoughts are meaningful. Conclusion: The results indicate that anxiety, stress, depression along with victim of bullying in female adolescents cause suicidal thoughts therefore preventing and reducing the risk at schools is absolutely necessary.

Full Text Available Objectives: A casual relationship between temperament, job stress and depressive symptoms has not been established yet. The purpose of this study was to assess the relationships between job stress, temperament and depressive symptoms in female nurses at a Japanese general hospital. Material and Methods: A self-report survey was conducted among 706 nurses. We measured job stress, temperament, and depressive symptoms using the Brief-Job Stress Questionnaire, the TEMPS-A and a screening scale of items from the Ministry of Health, Labour and Welfare of Japan. In order to examine the causal relationship between the measures the stepwise multiple regression and path analyses were used. Results: Depressive symptoms were modestly correlated with job stress (γ = -0.23-0.30. Except for hyperthymic temperament measures, the correlations between depressive symptoms and temperament types were significant and moderate (γ = 0.36-0.50. Overtime, job control as well as depressive and cyclothymic types of temperament were significantly correlated with depressive symptoms (β = 0.15, p < 0.05; β = 0.19, p < 0.01; β = 0.26, p < 0.001; β = 0.32, p < 0.001, respectively. Path-analysis revealed that depressive and cyclothymic types of temperament influenced depressive symptoms both directly (β = 0.67, p < 0.001 and indirectly via job stress (β = 0.35, p < 0.001 from temperament to job stress; β = 0.20, p < 0.05 from job stress to depressive symptoms. Irritable and anxious types of temperament and quantitative job overload did not contribute to the path-analytic model. Conclusions: Health care professionals should consider temperament, especially depressive and cyclothymic types, in order to help employees cope better with job stress factors. We need further research about the effective intervention to help employees better cope with their job stress.

Both HIV infection and Methamphetamine (Meth) use disorders are associated with greater depressive symptoms and oxidative stress; whether the two conditions would show additive or interactive effects on the severity of depressive symptoms, and whether this is related to the level of oxidative stress in the CNS is unknown. 123 participants were evaluated, which included 41 HIV-seronegative subjects without substance use disorders (Control), 25 with recent (HIV-seropositive subjects without substance use disorders (HIV) and 23 HIV+Meth subjects. Depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Scale (CES-D), and oxidative stress markers were evaluated with glutathione (GSH), 4-hydroxynonenal (HNE), and activities of gamma-glutamyltransferase (GGT) and glutathione peroxidase (GPx) in the cerebrospinal fluid (CSF). Compared with Controls, HIV subjects had higher levels of HNE (+350%) and GGT (+27%), and lower level of GSH (-34%), while Meth users had higher levels of GPx activity (+23%) and GSH (+30 %). GGT correlated with GPx, and with age, across all subjects (p HIV groups, but not in Meth and HIV+Meth groups. HIV and Meth use had an interactive effects on depressive symptoms, but did not show additive or interactive effects on oxidative stress. The differential relationship between depressive symptoms and oxidative stress response amongst the four groups suggest that depressive symptoms in these groups are mediated through different mechanisms which are not always related to oxidative stress.

There is ample evidence that depression is000 a common comorbid health issue in people with type 1 or type 2 diabetes. Reviews have also concluded that depression in diabetes is associated with higher HbA1c levels, less optimal self-care behaviours, lower quality of life, incident vascular...... complications and higher mortality rates. However, longitudinal studies into the course of depression in people with type 1 diabetes remain scarce.

The current study examined associations over an 18-month period between maternal work stressors, negative work-family spillover, and depressive symptoms in a sample of 414 employed mothers with young children living in six predominantly nonmetropolitan counties in the Eastern United States. Results from a one-group mediation model revealed that a less flexible work environment and greater work pressure predicted higher levels of depressive symptoms, and further, that these associations were mediated by perceptions of negative work-family spillover. Additionally, results from a two-group mediation model suggested that work pressure predicted greater perceptions of spillover only for mothers employed full-time. Findings suggest the need for policies that reduce levels of work stress and help mothers manage their work and family responsibilities.

The depression-distortion hypothesis posits that depressed mothers report child characteristics in a negatively-biased manner, motivating research on discrepant reporting between depressed mothers and their children. However, the literature has predominately focused on report discrepancies of youth psychopathological and behavioral outcomes, with limited focus on youth stress despite the marked increase of stressful events during adolescence. The current study investigated whether the presence versus absence of a maternal history of major depressive disorder differentially influenced reporting of adolescent stress when compared to her child's report, utilizing a community sample of diverse adolescents. As hypothesized, mothers with a history of depression were more likely to report more youth stress than their children reported. Specifically, mothers with a history of depression were more likely than nondepressed mothers to report more familial, social, and youth-dependent stressors relative to their children; nondepressed mothers were more likely to report less independent stressors than their children.

Acculturative stress is a risk factor for depression, and may be important in the risk for depression among acculturating Japanese adolescents. However, little to no research has been published on the mental health of acculturating Japanese adolescents. Further, although family cohesion has been shown to be protective against depression across ethnic groups, no prior research has examined family cohesion as a protective factor for Japanese adolescents. To examine these relationships, 26 Japanese temporary resident adolescents and 76 parents in the Midwest were recruited to participate. Moderate to strong correlations between acculturative stress, depression, likelihood for and seriousness of family conflict were found. A regression analysis found that likelihood for family conflict moderated the relationship between acculturative stress and depression. Findings broaden our understanding of the role of acculturative stress and family conflict on depression risk for Japanese adolescent immigrants.

Prolonged stress may lead to mental illness, but the prevalence of stress in a working age population seeking primary health care for whatever reason, is unknown. This paper seeks to examine to what extent this group perceives stress, as well as symptoms of burnout/exhaustion, depression and anxiety. In 2009, 587 primary health care patients aged 18-65 years (377 women, 210 men), with an appointment with a primary health care physician, participated in the study. A screening questionnaire with questions about age, gender, marital status, employment, reason for medical consultation, and the QPS Nordic screening question about stress was distributed:" Stress is defined as a condition where you feel tense, restless, anxious or worried or cannot sleep at night because you think of problems all the time. Do you feel that kind of stress these days? There were five possible answers; "not at all" and "only a little" (level 1),"to some extent" (level 2),"rather much" and "very much" (level 3). In a second step, symptoms of burnout/exhaustion (Shirom-Melamed Burnout Questionnaire and the Self-rated Exhaustion Disorder instrument) and anxiety/depression (Hospital Depression and Anxiety scale) were assessed among those with higher levels of perceived stress. 345 (59%) of the study patients indicated stress levels 2 or 3 (237 women and 108 men). Women more often indicated increased levels of stress than men. Two thirds of the participants expressing stress levels 2-3 indicated a high degree of burnout, and approximately half of them indicated Exhaustion Disorder (ED). Among highly stressed patients (level 3), 33% reported symptoms indicating possible depression and 64% possible anxiety. More than half of this working age population perceived more than a little stress, as defined, women to a greater extent than men. Symptoms of burnout and exhaustion were common. A high level of perceived stress was often accompanied by symptoms of depression and/or anxiety.

This study examined the prevalence of perceived stress and depressive symptoms in cancer survivors and their family members compared with subjects without cancer and without family members with cancer. The subjects of this cross-sectional study were adults ≥19 years old who participated in the 2012 Korea Community Health Survey. Stress and depressive symptoms in cancer survivors and their family members were assessed and compared to symptoms in control groups by chi-square tests and multiple logistic regression analyses. Of the 6783 cancer survivors, 26.9% and 8.7% reported having stress and depressive symptoms, respectively, and 27.7% and 5.9% of family members of cancer survivors reported having stress and depressive symptoms, respectively. Cancer survivors showed higher adjusted odds ratio (aOR) for stress (aOR = 1.26, 95% confidence interval (CI) = 1.16-1.37) and depressive symptoms (aOR = 1.82, 95% CI = 1.57-2.11) than subjects without cancer history. Family members of cancer survivors showed a higher OR for stress and depressive symptoms than subjects without a family member who survived cancer. Cancer survivors and family members of cancer survivors had more stress and depressive symptoms than controls. Careful management for cancer patients and their family members should include screening for stress and depression to improve mental health associated with cancer survivorship.

Chronic headache in adolescents is frequent and often associated with anxiety and depression. The present study investigated, whether psychological and physical stress symptoms have an infl uence on the occurrence of anxiety and depression and what is the role of stress coping. The sample consisted of 77 15 years old girls with chronic headache and 72 girls, who served as controls. Stress symptoms and stress coping were measured with the Stressverarbeitungsfragebogen für Kinder und Jugendliche (Coping with Stress Questionnaire for Children and Adolescents), depression was assessed by the Depression Inventory for Children and Adolescents, anxiety by the State-Trait Anxiety Inventory for Children. Linear regression was used to analyze the relationship between stress factors and anxiety resp. depression. Physical stress symptoms were related to anxiety, but not to depression. Coping strategies of the depressed as well as the anxious children were characterized by stress reinforcing behaviors. The results point to focusing on physical symptoms in the anxious headache patients and to avoidance coping in the depressed children.

Stress-induced disturbance of the hypothalamic-pituitary-adrenal (HPA) axis is strongly implicated in incidence of mood disorders. A heightened neuroinflammatory response and oxidative stress play a fundamental role in the dysfunction of the HPA axis. We have previously demonstrated that iptakalim (Ipt), a new ATP-sensitive potassium (K-ATP) channel opener, could prevent oxidative injury and neuroinflammation against multiple stimuli-induced brain injury. The present study was to demonstrate the impacts of Ipt in stress-induced HPA axis disorder and depressive behavior. We employed 2 stress paradigms: 8 weeks of continuous restraint stress (chronic restraint stress, CRS) and 2h of restraint stress (acute restraint stress, ARS), to mimic both chronic stress and severe acute stress. Prolonged (4 weeks) and short-term (a single injection) Ipt treatment was administered 30min before each stress paradigm. We found that HPA axis was altered after stress, with different responses to CRS (lower ACTH and CORT, higher AVP, but normal CRH) and ARS (higher CRH, ACTH and CORT, but normal AVP). Both prolonged and short-term Ipt treatment normalized stress-induced HPA axis disorders and abnormal behaviors in mice. CRS and ARS up-regulated mRNA levels of inflammation-related molecules (TNFα, IL-1β, IL-6 and TLR4) and oxidative stress molecules (gp91phox, iNOS and Nrf2) in the mouse hypothalamus. Double immunofluorescence showed CRS and ARS increased microglia activation (CD11b and TNFα) and oxidative stress in neurons (NeuN and gp91phox), which were alleviated by Ipt. Therefore, the present study reveals that Ipt could prevent against stress-induced HPA axis disorders and depressive behavior by alleviating inflammation and oxidative stress in the hypothalamus.

Self-reported depressive experiences are common among university students. However, most studies assessing depression in university students are cross-sectional, limiting our understanding of when in the academic year risk for depression is greatest and when interventions may be most needed. We examined within-person change in depressive symptoms from September to April. Study 1 (N = 198; 57% female; 72% white; Mage = 18.4): Depressive symptoms rose from September, peaked in December, and fell across the second semester. The rise in depressive symptoms was associated with higher perceived stress in December. Study 2 (N = 267; 78.7% female; 67.87% white; Mage = 21.25): Depressive symptoms peaked in December and covaried within persons with perceived stress and academic demands. The results have implications for understanding when and for whom there is increased risk for depressive experiences among university students.

Diabetes mellitus is a highly prevalent condition in Malaysia, increasing from 11.6% in 2006 to 15.2% in 2011 among individuals 18 years and above. Co-morbid depression in diabetics is associated with hyperglycemia, diabetic complications and increased health care costs. The aims of this study are to determine the prevalence and predictors of depression, anxiety and stress symptoms in Type II diabetics attending government primary care facilities in the urban area of Klang Valley, Malaysia. The study was cross sectional in design and carried out in 12 randomly selected primary care government clinics in the Klang Valley, Malaysia. A total of 2508 eligible consenting respondents participated in the study. The Depression, Anxiety and Stress Scale (DASS) 21 questionnaire was used to measure depression, anxiety and stress symptoms. Data was analyzed using the SPSS version 16 software using both descriptive and inferential statistics. The prevalence of depression, anxiety and stress symptoms among Type II diabetics were 11.5%, 30.5% and 12.5% respectively. Using multiple logistic regression, females, Asian Indians, marital status (never married, divorced/widowed/separated), a family history of psychiatric illness, less than 2 years duration of diabetes and current alcohol consumption were found to be significant predictors of depression. For anxiety, unemployment, housewives, HbA1c level of more than 8.5%, a family history of psychiatric illness, life events and lack of physical activity were independent risk factors. Stress was significantly associated with females, HbA1c level of more than 8.5%, presence of co-morbidity, a family history of psychiatric illness, life events and current alcohol consumption. For depression (adjusted OR 2.8, 95% CI 1.1; 7.0), anxiety (adjusted OR 2.4, 95% CI 1.1;5.5) and stress (adjusted OR 4.2, 95% CI 1.8; 9.8), a family history of psychiatric illness was the strongest predictor. We found the prevalence of depression, anxiety and stress

Multiple theories posit that people with a history of depression are at higher risk for a depressive episode than people who have never experienced depression, which may be partly due to differences in stress-reactivity. In addition, both the dynamic model of affect and the broaden-and-build theory suggest that stress and positive affect interact to predict negative affect, but this moderation has never been tested in the context of depression history. The current study used multilevel modeling to examine these issues among 1,549 college students with or without a history of depression. Students completed a 30-day online diary study in which they reported daily their perceived stress, positive affect, and negative affect (including depression, anxiety, and hostility). On days characterized by higher than usual stress, students with a history of depression reported greater decreases in positive affect and greater increases in depressed affect than students with no history. Furthermore, the relations between daily stress and both depressed and anxious affect were moderated by daily positive affect among students with remitted depression. These results indicate that students with a history of depression show greater stress-reactivity even when in remission, which may place them at greater risk for recurrence. These individuals may also benefit more from positive affect on higher stress days despite being less likely to experience positive affect on such days. The current findings have various implications both clinically and for research on stress, mood, and depression. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

The current study compared two competing theories of the stress generation model of depression (stress causation vs. stress continuation) using interview-based measures of episodic life stress, as well as interpersonal and noninterpersonal chronic life stress. We also expanded on past research by examining anxiety disorders as well as depressive disorders. In addition, we examined the role of neuroticism and extraversion in these relationships. Participants were 627 adolescents enrolled in a two-site, longitudinal study of risk factors for depressive and anxiety disorders. Baseline and follow-up assessments were approximately one year apart. Results supported the stress causation theory for episodic stress generation for anxiety disorders, with neuroticism partially accounting for this relationship. The stress causation theory was also supported for depression, but only for more moderate to severe stressors; neuroticism partially accounted for this relationship as well. Finally, we found evidence for interpersonal and noninterpersonal chronic life stress continuation in both depressive and anxiety disorders. The present findings have implications regarding the specificity of the stress generation model to depressive disorders, as well as variables involved in the stress generation process.

Full Text Available Introduction: Adolescence is a stressful period due to physical, psychological, sexual changes, and the presence of psychiatric disorders such as depression, anxiety, and stress at this stage of life is a matter of concern. Objectives: The objectives of the study were to determine the prevalences of depression, anxiety, and stress among higher secondary school students of Imphal and to determine the association between depression, anxiety, and stress and selected variables such as gender, standard, and religion. Materials and methods: From September 2014 to October 2014, a cross-sectional study was conducted among higher secondary school students of Imphal. The sample size was calculated to be 750. Seven schools were randomly selected, and all the students in that school were enrolled in the study. The study tool used was a questionnaire containing DASS (Depression Anxiety Stress Scale and sociodemographic characteristics. Results: The prevalences of depression, anxiety, and stress among 830 valid respondents were 19.5%, 24.4%, and 21.1%, respectively. In total, 81.6% of the respondents had at least one of the studied disorders and 34.7% of the respondents had all the three negative states. The prevalences of depression, anxiety, and stress were high among females and were significant for anxiety (P = 0.00 and stress (P = 0.04. The prevalences of depression and stress were significantly higher among 12th standard students with P-values of 0.00 and 0.02. Conclusion: The prevalences of depression, anxiety, and stress were high with anxiety and stress significantly higher among females, whereas prevalences of depression and stress were significantly higher among 12th standard students. More studies are recommended to determine the factors leading to these mental disorders.

Depression is a common co-morbid disorder in substance use disorder (SUD) patients. Hence, valid instruments are needed to screen for depression in this subpopulation. In this study, the predictive validity of the Depression, Anxiety and Stress Scale (DASS-21) for the presence of a depressive disorder was investigated in SUD inpatients. Furthermore, differences between DASS-21 scores at intake and those recorded one week after inpatient detoxification were assessed in order to determine the measurement point of the assessment of the DASS-21 leading to the best predictive validity. The DASS-21 was administered to 47 patients at intake and shortly after inpatient detoxification. The results of the DASS-21 were compared to the Mini International Neuropsychiatric Interview (MINI), which served as the gold standard. Levels of sensitivity and specificity of 78-89% and 71-76% were found for the DASS-21 assessed after detoxification, satisfactorily predicting depression as diagnosed with the MINI. Total DASS-21 scores as well as the DASS subscale for depression were significantly reduced at the second measurement, compared to the DASS at intake. We conclude that the DASS-21 may be a suitable instrument to screen for depressive disorders in SUD patients when administered (shortly) after detoxification. Future research is needed to support this conclusion. © 2017 The Author(s) Published by S. Karger AG, Basel.

The stress response is mediated by the hypothalamo-pituitary-adrenal (HPA) system. Activity of the corticotropin-releasing hormone (CRH) neurons in the hypothalamic paraventricular nucleus (PVN) forms the basis of the activity of the HPA-axis. The CRH neurons induce adrenocorticotropin (ACTH) release from the pituitary, which subsequently causes cortisol release from the adrenal cortex. The CRH neurons co-express vasopressin (AVP) which potentiates the CRH effects. CRH neurons project not only to the median eminence but also into brain areas where they, e.g., regulate the adrenal innervation of the autonomic system and affect mood. The hypothalamo-neurohypophysial system is also involved in stress response. It releases AVP from the PVN and the supraoptic nucleus (SON) and oxytocin (OXT) from the PVN via the neurohypophysis into the bloodstream. The suprachiasmatic nucleus (SCN), the hypothalamic clock, is responsible for the rhythmic changes of the stress system. Both centrally released CRH and increased levels of cortisol contribute to the signs and symptoms of depression. Symptoms of depression can be induced in experimental animals by intracerebroventricular injection of CRH. Depression is also a frequent side effect of glucocorticoid treatment and of the symptoms of Cushing's syndrome. The AVP neurons in the hypothalamic PVN and SON are also activated in depression, which contributes to the increased release of ACTH from the pituitary. Increased levels of circulating AVP are also associated with the risk for suicide. The prevalence, incidence and morbidity risk for depression are higher in females than in males and fluctuations in sex hormone levels are considered to be involved in the etiology. About 40% of the activated CRH neurons in mood disorders co-express nuclear estrogen receptor (ER)-alpha in the PVN, while estrogen-responsive elements have been found in the CRH gene promoter region, and estrogens stimulate CRH production.

One of the problems that mothers of neonates having colostomy face is their disability in caring colostomy at home. This article is going to demonstrate the impact of educational program for these mothers on their sense of empowerment in caring their neonates. This clinical trial was performed in the Neonatal Intensive Care Units (NICUs) to evaluate the level of stress, anxiety and depression of mothers of neonates having colostomy before and after the educational program. In this program, 42 mothers were divided into two groups: experimental group (21 mothers who went under educational plan) and control group (21 mothers who only received the routine care). The levels of stress, anxiety and depression in all mothers were evaluated before and after the educational program with DASS 21 questionnaire. The results showed that educational program in the NICU for experimental groups made them independent and also empowered to care better for their babies. In addition, their depression, anxiety and stress levels were decreased. Since the educational program led to a decrease in the levels of stress, anxiety and depression in mothers, this program is recommended to mothers of neonates having colostomy.

Full Text Available It is known that interpersonal relations are an important aspect of human life and that any problemconcerning this aspect has a direct effect on people’s psychological well-being. From this fact, there arises the need of moreexplanation and research on perfectionism and depression which are accepted to have important effects on interpersonalrelations. The purpose of this study was to investigate the relationships between university students’ perfectionismtendencies and depression levels in relation to gender, socio-economic status, mother’s education level, father’s educationlevel, and parenting styles. In order to collect data, 340 students (170 females; 170 males were randomly recruited fromMugla University, Faculty of Education's various departments. The instruments held to collect data were the InformationForm, Multidimensional Perfectionism Scale and Beck Depression Inventory. SPSS for Windows was used to analyze thedata gathered. The group differences were tested by t-test and F statistics. Correlational statistics was employed to search forrelationships between all variables. The findings showed that there is a difference between the gender and SES according tothe scores of the university students that they got from the subdimensions of perfectionism “concern over mistakes” and“personal standarts”; mother’s education level, father’s education level and parenting styles according to the scores that theygot from “parental criticism” and “parental expectations”; the gender, socio-economic status and parenting styles accordingto the scores that they got from depression. The results are discussed in the light of previous findings and in the context ofperfectionism and depression, conducting future research for implications as well.

The current study was aimed to investigate the correlations between immobility time in the forced swimming test (FST, a behavioral indicator of stress level) and hippocampal monoamine levels (markers of depression), plasma adrenalin level (a peripheral marker of stress) as well as fluoro-jade C staining (a marker of neurodegeneration). Male Sprague-Dawley rats were subjected to acute, sub-chronic (7 d) or chronic (14 d) FSTs and immobility time was recorded. Levels of noradrenalin, serotonin and dopamine in the hippocampus, and adrenalin level in the plasma were quantified by high-performance liquid chromatography with electrochemical detection. Brain sections from rats after chronic forced swimming or rotenone treatment (3 mg/kg subcutaneously for 4 d) were stained with fluoro-jade C. The rats subjected to swimming stress (acute, sub-chronic and chronic) showed long immobility times [(214 +/- 5), (220 +/- 4) and (231 +/- 7) s, respectively], indicating that the animals were under stress. However, the rats did not exhibit significant declines in hippocampal monoamine levels, and the plasma adrenalin level was not significantly increased compared to that in unstressed rats. The rats that underwent chronic swimming stress did not manifest fluoro-jade C staining in brain sections, while degenerating neurons were evident after rotenone treatment. The immobility time in the FST does not correlate with markers of depression (monoamine levels) and internal stress (adrenalin levels and neurodegeneration), hence this parameter may not be a true indicator of stress level.
Full Text Available Background and Objectives: Heart failure is a life-threatening illness in which panic disorder, anxiety, depression, and death expectation are constantly experienced. This study, thus, determined to examine the relationship between spiritual health and depression, anxiety, and stress in patients with heart failure. Methods: This study was a descriptive-correlational investigation that was performed on 150 patients with heart failure in selected Ardabil teaching hospitals in 2014. Data was collected using Demographic Questionnaire, Ellison-Paloutzian Spiritual Well-Being Scale, and Depression, Anxiety, and Stress Scale (DASS-21. They were, then, analyzed using SPSS, descriptive statistical method, Pearson’s correlation coefficient, and multivariable regression analysis. Results: The results of this study showed that the spiritual wellbeing level of most subjects (75.3% was in the range of medium. Mean scores of religious and existential aspects of spiritual well-being were obtained to be 33.26±1.247 and 45.76±1.328, respectively. In addition, depression, anxiety, and stress levels of most research units were in the medium range. Pearson’s correlation coefficient showed that there was a statistically significant relationship between depression, anxiety, and stress in all aspects of spiritual wellbeing (r=-0.592, P<0.01. Conclusion: Results indicated that an increase in spiritual health would be a concomitant of a reduction in depression, anxiety, and stress levels in heart failure patients. Based on the results and importance of spiritual health, an improvement of proficiencies of medical and paramedical communities in offering spiritual healthcares appears to be mandatory.

The assessment of mental distress is a central aspect in pain research and treatment. Particularly for depression the comorbidity with pain poses methodological and conceptual challenges. This study examined the psychometric properties of the short version of the depression, anxiety and stress scale (DASS), used in both pain research and treatment and constructed to overcome the particular problems by omitting somatic items and concentrating on the psychological core aspects of depression, anxiety and stress. The psychometric properties of the DASS-21 were compared between patients with pain and various people without any pain problems (N = 950). The DASS has three subscales, depression, anxiety and stress, each with seven items. The construct validity of the DASS was examined using the hospital anxiety and depression scale (HADS) for anxiety and depression and the general depression scale (Allgemeine Depressionsskala, ADS) for depression. The sensitivity and specificity for depression were determined against a structured interview for diagnostic and statistical manual of mental disorders (DSM-IV) and compared with the Center for Epidemiological Studies depression scale (CESD) and HADS in pain patients. Cronbach's alpha of the DASS for the depression subscale was at least 0.91, while the anxiety and stress subscales had Cronbach alphas of 0.78-0.82 and 0.81-0.89, respectively. Although the depression subscale has only 7 items, it is just as reliable as the ADS with 21 items. It also has a better sensitivity and specificity than the HADS in identifying clinical patients with depression. The DASS is a reliable questionnaire, free to use and brief to administer; therefore, it is an alternative to the previously used instruments for the screening of depression. Furthermore, the subscale stress measures irritability and tension, which are important aspects of pain experience but underused in assessment procedures for the diagnosis and treatment evaluation of patients

The stress generation hypothesis posits that individuals actively contribute to stress in their lives. Although stress generation has been studied frequently in the context of depression, few studies have examined whether this stress generation process is unique to depression or whether it occurs in other disorders. Although evidence suggests that stress contributes to the development of eating disorders, it is unclear whether eating disorders contribute to subsequent stress. A prospective design was used to examine the influence of eating disorder symptoms on negative life stressors. Two hundred and ninety female undergraduates completed questionnaires at two time points that examined eating disorder, depressive and anxiety symptoms and the presence of negative life events. Regression analyses found that while eating disorder symptoms (i.e. bulimic symptoms and drive for thinness) were independent, significant predictors of negative life events, they did not predict negative life events above and beyond symptoms of depression. Limitations include the use of self-report measures and a college-based sample, which may limit generalizability of the results. Findings suggest that if stress generation is present in individuals with symptoms of eating disorders, it is likely attributable to symptoms of depression. Thus, it may be important for clinicians to target depressive symptoms in order to reduce the frequency of negative life stressors among individuals with eating disorders.

Full Text Available A exposição a fatores estressantes tem papel importante no desenvolvimento de transtornos depressivos. Os mecanismos envolvidos nesta relação, no entanto, ainda são pouco conhecidos, mas algumas evidências sugerem a participação da formação hipocampal: 1. o estresse pode causar alterações plásticas no hipocampo, que incluem remodelação dendrítica e inibição de neurogênese. Drogas antidepressivas impendem estes efeitos, possivelmente por aumentarem a expressão de fatores neurotróficos; 2. a facilitação da neurotransmissão serotoninérgica no hipocampo atenua conseqüências comportamentais do estresse e produz efeitos antidepressivos em modelos animais; 3. o antagonismo do principal neurotransmissor excitatório no hipocampo, o glutamato, produz efeitos semelhantes; 4. o hipocampo parece estar "hiperativo" em animais mais sensíveis em modelos de depressão e em humanos resistentes à antidepressivos; 5. o hipocampo, em conjunto com o complexo amigdalar, parece ter papel fundamental na consolidação e evocação de memórias aversivas. Não obstante estas evidências, o desafio futuro será o de tentar integrar os resultados destes diferentes campos (farmacológico, molecular, eletrofisiológico, clínico em uma teoria unificadora sobre o papel do hipocampo na regulação do humor e seus transtornos bem como nos efeitos de tratamentos antidepressivos.Stress exposure is an important factor in the development of depressive disorders. Although the mechanisms of this relationship are largely unknown, several pieces of evidence point to an involvement of the hippocampal formation: 1. stressful stimuli cause remodeling of hipocampal pyramidal cells and inhibit neurogenesis in the dentate gyrus. Antidepressive drugs attenuate these effects, probably by increasing the expression of neurotrophic factors; 2. facilitation of serotonergic neurotransmission in the hippocampus attenuates behavioral consequences of stress and produce

The current study examined the relationships among combat exposure, presence of and search for meaning in life, general and social self-efficacy, and both posttraumatic stress disorder (PTSD) and depression symptom severity for a Veteran sample (N = 93). Participants completed an online survey comprising the Combat Exposure Scale, Meaning in Life Questionnaire, Self-Efficacy Scale, Depression subscale of the Depression, Anxiety, Stress Scales-21, and PTSD Checklist-Specific Stressor version. The majority of participants were male and Caucasian. Participants served in various service eras To determine factors that predicted PTSD and depression severity, separate hierarchical linear regressions were performed. In the final PTSD model, rank, combat exposure, and general self-efficacy were significant predictors, with officer rank, lower combat exposure, and higher general self-efficacy associated with lower PTSD severity. The interaction between combat exposure and general self-efficacy was also significant, with self-efficacy moderating the relationship between combat exposure and PTSD severity. For depression, rank, presence of meaning in life, and general self-efficacy were significant predictors in the model, with officer rank, higher presence of meaning in life, and general self-efficacy associated with lower depression severity. A focus on strengthening self-efficacy may assist with lower levels of PTSD and depression symptomatology after combat trauma. © 2014 Wiley Periodicals, Inc.

Abstract Exposure to stress is highly correlated with the emergence of mood-related illnesses. Because major depressive disorder often emerges in adolescence, we assessed the effects of social defeat stress on responses to depressive-like behaviors in juvenile mice. To do this, postnatal day (PD) 35 male c57BL/6 mice were exposed to 10 days of social defeat stress (PD35-44), while control mice were handled daily. Twenty-four hours after the last episode of defeat (PD45), separate groups of mice were tested in the social interaction, forced swimming, sucrose preference, and elevated plus-maze behavioral assays (n = 7-12 per group). Also, we examined body weight gain across days of social defeat and levels of blood serum corticosterone 40 min after the last episode of defeat stress. Our data indicates that defeated mice exhibited a depressive-like phenotype as inferred from increased social avoidance, increased immobility in the forced swim test, and reduced sucrose preference (a measure of anhedonia), when compared to non-defeated controls. Defeated mice also displayed an anxiogenic-like phenotype when tested on the elevated plus-maze. Lastly, stressed mice displayed lower body weight gain, along with increased blood serum corticosterone levels, when compared to non-stressed controls. Overall, we show that in adolescent male c57BL/6 mice, social defeat stress induces a depression- and anxiety-like phenotype 24 h after the last episode of stress. These data suggest that the social defeat paradigm may be used to examine the etiology of stress-induced mood-related disorders during adolescence.

This study was conducted to examine the level of infertility stress, marital adjustment, depression, and quality of life in infertile couples and assess the actor and partner effects in these areas using the actor-partner interdependence model. Cross-sectional study. Participants were 121 infertile couples. After pilot study, data were collected from November 2012 to March 2013 using the following questionnaires: the Fertility Quality of Life, Fertility Problem Inventory, Revised Dyadic Adjustment Scale, and Beck Depression Inventory. There was a gender difference in infertility stress, depression, and quality of life. Infertility stress had actor and partner effects on the quality of life. Marital adjustment had an actor effect on the quality of life for the wives. Depression had actor and partner effects on quality of life for the wives, but only an actor effect for the husbands. This study found that there were actor and partner effects of infertility stress, marital adjustment, and depression on the quality of life in infertile couples. These findings may help nurses be aware of such effects and can be used as a baseline data in the development of nursing interventions for infertile couples.

The thesis of this review is that oxidative stress is the central factor in major depressive disorder (MDD) and Alzheimer’s disease (AD). The major elements involved are inflammatory cytokines, the hypothalamic pituitary axis, the hypothalamic pituitary gonadal, and arginine vasopressin systems, which induce glucocorticoid and “oxidopamatergic” cascades when triggered by psychosocial stress, severe life threatening events, and mental-affective and somatic diseases. In individuals with a genomic vulnerability to depression these cascades may result in chronic depression-anxiety-stress spectra, resulting in MDD and other known depressive syndromes. In contrast, in subjects with genomic vulnerability to Alzheimer’s disease, oxidative stress-induced brain damage triggers specific antioxidant defenses, i.e. increased levels of amyloid-β (Aβ) and aggregation of hyper-phosphorylated tau, resulting in paired helical filaments and impaired functions related to the ApoEε4 isoform, leading to complex pathological cascades culminating in AD. Surprisingly, all the AD associated molecular pathways mentioned in this review have been shown to be similar or analogous to those found in depression, including structural damage, i.e. hippocampal and frontal cortex atrophy. Other interacting molecular signals, i.e. GSK-3β, convergent survival factors (brain-derived neurotrophic factor and heat shock proteins), and transition-redox metals are also mentioned to emphasize the vast array of intermediates that could interact via comparable mechanisms in both MDD and AD.

There is a great deal of evidence about the mental health implications of physical child abuse and environmental stressors, or hardships that people experience at the household and neighborhood level (e.g., neighborhood violence; economic hardship, substance abuse, or conflict among family members). Yet, studies often focus on either abuse or environmental stress, not both, or examine abuse and environmental stressors as a combined set of experiences. Less is known, therefore, about how child abuse and environmental stress might work as either distinct or interrelated risks to diminish mental health over time. In this longitudinal study, we used path analyses to examine the cumulative effects of physical child abuse and environmental stressors on adult depressive symptoms among a sample of children followed into adulthood (N = 356). The goal was to assess whether chronic physical child abuse remains an independent predictor of adult outcomes once we accounted for the cumulative effects of household and neighborhood stressors across the lifecourse. Cumulative measures of physical child abuse and environmental stress each independently predicted a higher likelihood of adult depressive symptoms (ß = .122, p < .01 and ß = .283, p < .001, respectively). After accounting for adolescent depressive symptoms, only cumulative environmental stressors independently predicted depressive symptoms (ß = .202, p < .001). Tests of the indirect effect of cumulative environmental stress on the relationship between cumulative physical abuse and adult depressive symptoms were marginally statistically significant. Results add to literature that examines child abuse, adversity, and lifecourse perspectives on health. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values. We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law. The questionnaire was then analyzed using its specific software to process the results related to the 7 dimensions. These results were compared using the Pearson correlation and multiple linear regression with the blood glucose values obtained from each subject. From the analysis of the data the following areas resulted critical, in other words linked to an intermediate (yellow area) or high (red area) condition of stress: sustain from managers, sustain from colleagues, quality of relationships and professional changes. A significant positive correlation (p work stress can be statistically associated with increased levels of blood glucose.
Full Text Available Clinical and experimental studies suggest a causal role of chronic stress for brain pathology and diseases e.g. depression and Alzheimer´s disease (AD as stress is strongly associated with neuronal and synaptic atrophy/loss resulting in impaired mood and/or cognition. Indeed, synaptic loss is a key underlying pathomechanism in both disorders while growing clinical evidence supports a pathological link between depression and AD pointing to shared neurobiological underpinnings and pathogenic mechanisms e.g. AD-related mechanisms, such as APP misprocessing, are also found to be affected in depression while depression predisposes individuals to develop AD. Based on the above, our studies have been conceived to contribute towards bridging the current gap monitoring AD-related mechanisms in the CMS (chronic mild stress animal model of depression before and after antidepressant treatment. We found that depressive status in these animals was accompanied by increased APP misprocessing and tau accumulation as well as neuronal atrophy in hippocampus and prefrontal cortex. Interestingly, antidepressant treatment with two different antidepressants reversed both biochemical and synaptic changes. Furthermore, we demonstrate the blockage of stress-triggered depressive behavior and neuronal/synaptic atrophy in animals lacking APP misprocessing and amyloid beta generation, further supporting the involvement of APP misprocessing in depressive pathology and behavior. Thus, this study forms the first in vivo approach to clarify the involvement of AD-related APP misprocessing on stress-driven synaptic pathology underlying depressive pathology.
Results: Participants in the study were parents of 26 male (65% and 14 female (35% autistic children. The average age of the children was 62.9+/-16.6 months. .Mothers had higher levels of depression and anxiety scores. Mothers of autistic children who participated in the study received higher scores on depression, state anxiety and trait anxiety compared to fathers. Among mothers, a significant relationship was found between level of education and level of state anxiety. Conclusion: The findings of this study show that mothers have higher levels of depression and anxiety compared to fathers. This finding might be explained with reference to customs and traditions of the Turkish society in which the study was conducted, which require women to take more responsiblity for family matters. It is recommended that special education and rehabilitation centers provide counseling to parents about the effects of having an autistic children on their lives, and advise them on seeking psychological help if necessary.

Previous research suggests that effects of caffeine on behaviour are positive unless one is investigating sensitive groups or ingestion of large amounts. Children are a potentially sensitive subgroup, and especially so considering the high levels of caffeine currently found in energy drinks. The present study used data from the Cornish Academies Project to investigate associations between caffeine (both its total consumption, and that derived separately from energy drinks, cola, tea, and coffee) and single-item measures of stress, anxiety, and depression, in a large cohort of secondary school children from the South West of England. After adjusting for additional dietary, demographic, and lifestyle covariates, positive associations between total weekly caffeine intake and anxiety and depression remained significant, and the effects differed between males and females. Initially, effects were also observed in relation to caffeine consumed specifically from coffee. However, coffee was found to be the major contributor to high overall caffeine intake, providing explanation as to why effects relating to this source were also apparent. Findings from the current study increase our knowledge regarding associations between caffeine intake and stress, anxiety, and depression in secondary school children, though the cross-sectional nature of the research made it impossible to infer causality.

The aim of the present study was to assess the association of psychological stress and social support with anxiety and depressive symptoms in Chinese newly diagnosed breast cancer patients. Four hundred and one patients with breast cancer were recruited. Their demographic characteristics, psychological stress and social support were determined with a structured questionnaire, and their anxiety and depressive symptoms were assessed with the Hospital Anxiety and Depression Scale. Psychological stressors caused by breast cancer diagnosed originated from five major sources, as determined by factor analysis. These included "Worrying about health being harmed, " "Fear of decline of physical function, " "Fear of work being harmed, " "Worry about daily life and social relationship being restricted, " and "Fear of family being harmed. " Hierarchical linear regression analysis indicated that, after adjusting for gender, age, marital status, educational level, and duration of illness, solid social support can alleviate such symptoms. The results of this study suggest that there are strong associations between patients' needs and psychological distress with newly diagnosed breast cancer. Social support might affect these associations in Chinese women with breast cancer.

This finding has been attributed to the reaction of having to care for a child with neurodevelopmental disorders. While there have been reports on autism spectrum disorder in Arab/Islamic countries such as Oman, there is no study from this region, to our knowledge, reporting the performance of indices of stress, anxiety, and depression among CASD. This study aimed to examine whether there is variation in the performance of indices of stress, depression, and anxiety explored via Depression, Anxiety and Stress Scale 21 among CASD, caregivers of children with intellectual disabilities, and caregivers of typically developing children. All indices of stress, depression, and anxiety were higher in CASD compared to other caregivers in the control group. This study corroborates with other studies carried out in other populations that caring for children impacts the mental health status of caregivers. Therefore, there are strong grounds to contemplate the mechanism to help such a vulnerable group of family caregivers. Keywords: stress, anxiety, depression, caregivers, autism, Oman

We investigated geographic concentration in elevated risk for a range of postdisaster trajectories of chronic posttraumatic stress symptom (PTSS) and depression symptoms in a longitudinal study (N = 561) of a Hurricane Ike affected population in Galveston and Chambers counties, TX. Using an unadjusted spatial scan statistic, we detected clusters of elevated risk of PTSS trajectories, but not depression trajectories, on Galveston Island. We then tested for predictors of membership in each trajectory of PTSS and depression (e.g., demographic variables, trauma exposure, social support), not taking the geographic nature of the data into account. After adjusting for significant predictors in the spatial scan statistic, we noted that spatial clusters of PTSS persisted and additional clusters of depression trajectories emerged. This is the first study to show that longitudinal trajectories of postdisaster mental health problems may vary depending on the geographic location and the individual- and community-level factors present at these locations. Such knowledge is crucial to identifying vulnerable regions and populations within them, to provide guidance for early responders, and to mitigate mental health consequences through early detection of mental health needs in the population. As human-made disasters increase, our approach may be useful also in other regions in comparable settings worldwide.

Post-traumatic stress disorder is common among North Korean refugees who have fled their country for economic, financial and humanitarian reasons. Co-morbid depression and anxiety are also common among North Korean refugees, due to the difficulties they have faced within their country and during their escape journey. Depression and anxiety complicate treatment for post-traumatic stress disorder, and lead to poorer outcomes. Thus, the aim of the present study was to provide a meta-analysis of studies investigating post-traumatic stress disorder, depression, and anxiety among North Korean refugees. Selected articles were published in English, and included measures of post-traumatic stress, and/or depression and anxiety. 10 studies were included in the depression meta-analysis, and 6 in the anxiety meta-analysis. A random-effects model revealed strong, significant associations between post-traumatic stress and depression, r=0.63, 95% CI (0.51, 0.72), pstress, depression and anxiety were higher among adults and those with more than five years outside of North Korea. Depression appears to be an important treatment focus for North Korean refugees with post-traumatic stress.

It has been suggested that elevated maternal social anxiety may play a disorder-specific role in maintaining childhood social anxiety disorder (SAD), but few studies have examined whether mothers of children with SAD are more socially anxious than mothers of children with other anxiety disorders (ANX). This study set out to examine whether symptoms of social anxiety were more severe amongst mothers of 7-12 year old children presenting for treatment with SAD (n = 260) compared to those presenting with ANX (n = 138). In addition, we examined whether there were differences between these two groups in terms of maternal and paternal general anxiety, depression, and stress. Parents of 7-12 year old children referred for treatment of SAD or ANX completed self-report questionnaire measures of emotional symptoms. Compared to mothers of children with ANX, mothers of children with SAD reported significantly higher levels of social anxiety, general anxiety, and depression. In addition, fathers of children with SAD reported significantly higher levels of anxiety, stress, and depression than fathers of children with ANX. This study is one of the few existing studies that have examined mothers' and fathers' psychopathology across different childhood anxiety disorders. Compared to parents of children with ANX, parents of children with SAD may have poorer mental health which may inhibit optimum child treatment outcomes for children with SAD. Thus, targeting parental psychopathology may be particularly important in the treatment of childhood SAD. Consideration of parental psychopathology may be particularly important in the treatment of childhood social anxiety disorder. Mothers of children with social anxiety disorder are more socially anxious than mothers of children with other anxiety disorders Fathers of children with social anxiety disorder are more anxious and depressed than fathers of children with other anxiety disorders Participants were predominantly of high

The purpose of the study is to identify the predictors of depression and intimate partner violence (IPV) among Latinos in rural Southeastern North Carolina. A sample of 291 migrant and seasonal farmworkers was interviewed to complete the demographic questionnaire, HITS (intimate violence tendency), Migrant Farmworker Stress Inventory, Center for Epidemiologic Studies Depression Scale (depression), and CAGE/4M (alcohol abuse). OLS regression and structural equation modeling were used to test the hypothesized relations between predictors of IPV and depression. The findings indicated that respondents reporting higher levels of stress also reported higher levels of IPV and depression. The goodness-of-fit statistics for the overall model again indicated a moderate fit of the model to the data (χ2 = 5,612, p square error for approximation = 0.09; adjusted goodness-of-fit index = 0.44; comparative fit index = 0.52). Although the findings were not robust to estimation in the structural equation models, the OLS regression models indicated direct associations between IPV and depression.

There is limited information on the characteristics of stressful life events in depressed pediatric clinical populations and the extent to which sex, age, and their interactions may influence the relations of life events and depression. Using a very large clinical sample of children and adolescents with major depressive disorder (MDD), we therefore examined life events in various ways, as well as their relations to age and sex. The study included a clinic-based sample of 434 children (ages 7-14) with a DSM-IV diagnosis of MDD and their mothers, and a school-based comparison sample of 724 children and their mothers. Life event information was obtained from the mothers. Children with MDD had twice the number of lifetime stressful events than did the comparison group, with very high levels of stressors by the age of 7-9 that stabilized across adolescence. In contrast, the comparison sample experienced a gradual increase in stressful life events as a function of age up to mid-adolescence. Parental health events, death of close relatives, and intrafamilial events were significantly associated with MDD diagnosis. There were significantly stronger associations between parental health- as well as death-event clusters and MDD diagnosis among younger children than adolescents. Geographical differences between the clinical and comparison samples, as well as possible parental reporting biases may affect the generalizability of these findings. The association between some stressful life events and MDD seems to be moderated by age, underscoring the need to examine specific events, as well as clusters of events. Better understanding of such interactions may facilitate early identification of possible risk factors for pediatric MDD.

Poor psychological health in medical students has been reported nationwide. This study estimated the prevalence of depression, anxiety and stress symptoms among medical students who were enrolled in a public university in Upper Egypt and determine the association of these morbidities with the students' basic socio-demographic variables. This cross-sectional study included 700 students. A self-administered, questionnaire for the socio-demographic characteristics, Depression Anxiety Stress Scale (DASS 21) and Pittsburgh Sleep Quality Index (PSQI) questionnaire were used for assessment. High frequencies of depression (65%), anxiety (73%) and stress (59.9%) were reported. Stress scores were significantly higher than depression and anxiety (P=0.001). 55.7% were poor sleepers. In univarate analysis, females, those living in the University campus/students' residence facility, in the preclinical years and with lower academic achievement had higher scores of DASS and PSQI compared to their comparative partners. Significant correlations were reported between stress with depression, anxiety and PQSI scores (P=0.0001). In multivariate analysis, stress scores were significantly associated with female sex, depression and anxiety scores. We conclude that depression, anxiety and stress symptoms are common in medical students of Assiut University relative to other schools and female gender was significantly correlated with these findings.

Co-morbid depression with post-traumatic stress disorder (PTSD) is often treatment resistant. In developing a preclinical model of treatment-resistant depression (TRD), we combined animal models of depression and PTSD to produce an animal with more severe as well as treatment-resistant depressive-like behaviours. Male Flinders sensitive line (FSL) rats, a genetic animal model of depression, were exposed to a stress re-stress model of PTSD [time-dependent sensitisation (TDS)] and compared with stress-naive controls. Seven days after TDS stress, depressive-like and coping behaviours as well as hippocampal and cortical noradrenaline (NA) and 5-hydroxyindoleacetic acid (5HIAA) levels were analysed. Response to sub-chronic imipramine treatment (IMI; 10 mg/kg s.c.×7 days) was subsequently studied. FSL rats demonstrated bio-behavioural characteristics of depression. Exposure to TDS stress in FSL rats correlated negatively with weight gain, while demonstrating reduced swimming behaviour and increased immobility versus unstressed FSL rats. IMI significantly reversed depressive-like (immobility) behaviour and enhanced active coping behaviour (swimming and climbing) in FSL rats. The latter was significantly attenuated in FSL rats exposed to TDS versus unstressed FSL rats. IMI reversed reduced 5HIAA levels in unstressed FSL rats, whereas exposure to TDS negated this effect. Lowered NA levels in FSL rats were sustained after TDS with IMI significantly reversing this in the hippocampus. Combining a gene-X-environment model of depression with a PTSD paradigm produces exaggerated depressive-like symptoms that display an attenuated response to antidepressant treatment. This work confirms combining FSL rats with TDS exposure as a putative animal model of TRD.

Ghrelin is orexigenic hormone primarily synthesized by endocrine X/A-like cells of gastric oxyntic mucosa to stimulate appetite and food intake along with regulation of growth hormone and insulin secretion; glucose and lipid metabolism; gastrointestinal motility; blood pressure, heart rate and neurogenesis. Furthermore, peripherally (after crossing the blood brain barrier) as well as centrally synthesized ghrelin (in the hypothalamus) regulates diverse functions of central nervous system including stress-associated behavioral functions. Exposure to stress alters the ghrelin levels and alteration in ghrelin levels significantly affects neuro-endocrinological parameters; metabolism-related physiology, behavior and mood. Studies have shown both anxiolytic and anxiogenic role of ghrelin suggesting its dual role in modulating anxiety-related behavior. However, it is proposed that increase in ghrelin levels during stress condition is an endogenous stress coping behavior and increased ghrelin levels may be required to prevent excessive anxiety. In preclinical and clinical studies, an elevation in ghrelin levels during depression has been correlated with their antidepressant activities. Ghrelin-induced modulation of stress and associated conditions has been linked to alteration in hypothalamic-pituitary-adrenal (HPA) axis; autonomic nervous system (mainly sympathetic nervous system and serotonergic neurotransmission. A reciprocal relationship has been reported between corticotropin-releasing hormone (CRH) and ghrelin as ghrelin increases the release of CRH, ACTH and corticosteroids; while CRH decreases the expression of ghrelin. Similarly, ghrelin increases the serotonin turnover and in turn, serotonin controls ghrelin signaling to modulate anxiety-related behavior. The present review discusses the dual role of ghrelin in stress and related behavioral disorders along with possible mechanisms.

In response to high levels of comorbidity and symptom overlap between posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and other disorders, much attention has been devoted to the role of specific and nonspecific symptoms among the disorders. The present study investigated the overlapping symptoms of PTSD and MDD in treatment-seeking veterans. Exploratory factor analyses were used to identify latent factors of both self-reported and clinician-rated symptoms of PTSD and MDD. Results of exploratory factor analyses supported a 2-factor model representing symptoms of depression and PTSD; however, a subset of PTSD symptoms, characterized by emotional numbing and dysphoria, loaded onto the depression factor, rather than the PTSD factor. These nonspecific PTSD symptoms were predictive of comorbid MDD and increased depression symptomatology in patients with PTSD. Together, these findings demonstrate the importance of accounting for nonspecific symptoms in diagnosis and treatment of PTSD, highlighting a need for revisions to our current diagnostics.

Family members of patients who die in an ICU are at increased risk of psychological sequelae compared to those who experience a death in hospice. This study explored differences in rates and levels of complicated grief (CG), posttraumatic stress disorder (PTSD), and depression between family members of patients who died in an ICU versus a non-ICU hospital setting. Differences in family members' most distressing experiences at the patient's end of life were also explored. The study was an observational cohort. Subjects were next of kin of 121 patients who died at a large, Midwestern academic hospital; 77 died in the ICU. Family members completed measures of CG, PTSD, depression, and end-of-life experiences. Participants were primarily Caucasian (93%, N = 111), female (81%, N = 98), spouses (60%, N = 73) of the decedent, and were an average of nine months post-bereavement. Forty percent of family members met the Inventory of Complicated Grief CG cut-off, 31% met the Impact of Events Scale-Revised PTSD cut-off, and 51% met the Center for Epidemiologic Studies Depression Scale depression cut-off. There were no significant differences in rates or levels of CG, PTSD, or depressive symptoms reported by family members between hospital settings. Several distressing experiences were ranked highly by both groups, but each setting presented unique distressing experiences for family members. Psychological distress of family members did not differ by hospital setting, but the most distressing experiences encountered at end of life in each setting highlight potentially unique interventions to reduce distress post-bereavement for family members.

The risk of cardiovascular disease is dramatically increasing in Africans (black). The prothrombotic stress response contributes to atherothrombotic disease and is modulated by depressive symptoms. We examined coagulation reactivity to acute mental stress and its relation to psychological well-being in Africans relative to Caucasians (white). A total of 102 African and 165 Caucasian school teachers underwent the Stroop Color-Word Conflict test. Circulating levels of von Willebrand factor (VWF) antigen, fibrinogen, and D-dimer were measured before and after the Stroop. Cardiovascular reactivity measures were also obtained. All participants completed the Patient Health Questionnaire-9 and the General Health Questionnaire-28 for the assessment of depressive symptoms and total psychological distress, respectively. After controlling for covariates, resting levels of VWF, fibrinogen, and D-dimer were higher in Africans than in Caucasians (all p-values ≤0.006). Depressive symptoms and psychological distress were not significantly associated with resting coagulation measures. Stress reactivity in VWF (pstress when compared with Caucasians. Ethnic differences in the vascular adrenergic stress response might partially explain this finding. Depressive symptoms were associated with exaggerated VWF reactivity in Africans relative to Caucasians. The clinical implications of these findings for Africans need further study.

The existence of a high co-morbidity between Alzheimer's disease (AD) and depression has been known for a long time. More interesting though are recent studies indicating that depression and number of depressive episodes earlier in life is associated with increased risk of AD development....... This suggests the existence of common neuropathological mechanisms behind depression and AD. Here we propose that the brain changes associated with depressive episodes that compromise the brain's ability to cope with stress may constitute risk factors for development of AD. Furthermore, in individuals...... serotonergic and cholinergic system, hypothalamic-pituitary-adrenal axis and brain derived neurotrophic factor, and discussed in relation to AD....

Metabolic syndrome and depression seem to share some common underlying mechanisms, although less is known about the impact of metabolic syndrome dietary treatments on depression. This study examined the association between a hypocaloric treatment designed to reduce metabolic syndrome features in self-perceived depression and the potential involvement of dietary components and oxidative stress changes. Analyses were based on volunteers (n = 55) with metabolic syndrome (age 50 ± 1 y.o.; 38M/17F), where depressive symptoms were assessed using the Beck Depression Inventory. Participants followed two hypocaloric diets (control diet and RESMENA diet) with the same energy restriction (-30% TCV) for six months. Depressive symptoms, dietary records, anthropometrical measurements, biochemical parameters and oxidative stress levels were analysed. Both diets improved self-perceived depression similarly (p = 0.528). Participants with lower depressive symptoms at baseline reported a significantly higher intake of omega-3 polyunsaturated fatty acids (p trend = 0.002). Interestingly, after adjusting for potential confounders, the increase in folate consumption (p = 0.011) and the decrease in plasma malondialdehyde levels (p = 0.012) throughout the intervention, were associated with the improvement in depressive symptoms. A higher intake of folate and a decline in malondialdehyde plasma levels during a weight loss intervention, were related to improvements in manifestations of depression (www.clinicaltrials.gov; NCT01087086).

In South Africa, alcohol use poses a public health burden. Hazardous alcohol use often co-occurs with psychological distress (e.g., depression and post-traumatic stress). However, the majority of the research establishing the relationship between alcohol use and psychological distress has been cross-sectional, so the nature of co-occurring changes in psychological distress and alcohol use over time is not well characterized. The objective of this study is to examine the longitudinal relationship between psychological distress and alcohol use among South African women who attend alcohol serving venues. Four waves of data were collected over the course of a year from 560 women in a Cape Town township who attended drinking venues. At each assessment wave, participants reported depressive symptoms, post-traumatic stress symptoms, and alcohol use. Multilevel growth models were used to: 1) assess the patterns of alcohol use; 2) examine how depressive symptoms uniquely, post-traumatic stress symptoms uniquely, and depressive and post-traumatic stress symptoms together were associated with alcohol use; and 3) characterize the within person and between person associations of depressive symptoms and post-traumatic stress symptoms with alcohol use. Women reported high levels of alcohol use throughout the study period, which declined slightly over time. Post-traumatic stress symptoms were highly correlated with depressive symptoms. Modeled separately, both within person and between person depressive and post-traumatic stress symptoms were uniquely associated with alcohol use. When modeled together, significant between person effects indicated that women who typically have more post-traumatic stress symptoms, when controlling for depressive symptoms, are at risk for increased alcohol use; however, women with more depressive symptoms, controlling for post-traumatic stress symptoms, do not have differential risk for alcohol use. Significant within person effects indicated an

Stress associated with the college transition can bring about depression and anxiety symptoms, but family relationships can reduce the impact of stress. We hypothesized that secure attachment to parents, comfort with talking about stressors, and family support would reduce the strength of the relationships between transition-related stress and…
It is by now widely recognized that acute and chronic stress have an impact on the immune system. Acute stress may have a stimulating effect on the immune system, while in the case of chronic stress--and in particular in depression--the immune system may be down-regulated. However, there is

Exposure to peer stress contributes to adolescent depression, yet not all youth experience these effects. Thus, it is important to identify individual differences that shape the consequences of peer stress. This research investigated the interactive contribution of cumulative peer stress during childhood (second-fifth grades) and executive…

Shuyusan, a traditional Chinese medicine, was shown to improve depression symptoms and behavioral scores, as well as increase 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacetic acid, and 5-hydroxytryptophan levels, in a rat model of chronic stress-induced depression. However, dopamine, noradrenalin, and 3-methoxy-4-hydroxyphenylglycol expressions remained unchanged following Shuyusan treatment. Compared with the model group, the number of 5-HT-positive neurons in layers 4-5 of the frontal cortex, as well as hippocampal CA1 and CA3 regions, significantly increased following Shuyusan treatment. These results suggested that Shuyusan improved symptoms in a rat model of chronic stress-induced depression with mechanisms that involved 5-HT, 5-HT metabolite, 5-HT precursor expressions.

Mediation analysis investigates whether a variable (i.e., mediator) changes in regard to an independent variable, in turn, affecting a dependent variable. Moderation analysis, on the other hand, investigates whether the statistical interaction between independent variables predict a dependent variable. Although this difference between these two types of analysis is explicit in current literature, there is still confusion with regard to the mediating and moderating effects of different variables on depression. The purpose of this study was to assess the mediating and moderating effects of anxiety, stress, positive affect, and negative affect on depression. Two hundred and two university students (males = 93, females = 113) completed questionnaires assessing anxiety, stress, self-esteem, positive and negative affect, and depression. Mediation and moderation analyses were conducted using techniques based on standard multiple regression and hierarchical regression analyses. The results indicated that (i) anxiety partially mediated the effects of both stress and self-esteem upon depression, (ii) that stress partially mediated the effects of anxiety and positive affect upon depression, (iii) that stress completely mediated the effects of self-esteem on depression, and (iv) that there was a significant interaction between stress and negative affect, and between positive affect and negative affect upon depression. The study highlights different research questions that can be investigated depending on whether researchers decide to use the same variables as mediators and/or moderators.

Long-term exposure to stress or high glucocorticoid levels leads to depression-like behavior in rodents; however, the cause remains unknown. Increasing evidence shows that astrocytes, the most abundant cells in the central nervous system (CNS), are important to the nervous system. Astrocytes nourish and protect the neurons, and serve as glycogen repositories for the brain. The metabolic process of glycogen, which is closely linked to neuronal activity, can supply sufficient energy substrates for neurons. The research team probed into the effects of chronic corticosterone (CORT) exposure on the glycogen level of astrocytes in the hippocampal tissues of male C57BL/6N mice in this study. The results showed that chronic CORT injection reduced hippocampal neurofilament light protein (NF-L) and synaptophysin (SYP) levels, induced depression-like behavior in male mice, reduced hippocampal glycogen level and glycogen synthase activity, and increased glycogen phosphorylase activity. The results suggested that the reduction of the hippocampal glycogen level may be the mechanism by which chronic CORT treatment damages hippocampal neurons and induces depression-like behavior in male mice.

Research suggests that exclusive breastfeeding may have a stress-protective role in postpartum depression; however, less is known about the underlying mechanisms by which this protection may occur or whether the protective relationship holds for women who mix breast and bottle feeding. To examine patterns of the stress response, inflammation, and depressive symptoms among women predominantly breastfeeding or bottle feeding their infants at 6 months postpartum. A part of a larger longitudinal study across 6 months postpartum investigating the psychoneuroimmunology (PNI) of postpartum depression. Prenatal clinics and community. One hundred nineteen postpartum women who met inclusion/exclusion criteria and followed up from the prenatal period to postpartum 6 months. Data were collected during seven home visits occurring during the 3rd trimester (weeks 32-36) and on postpartum days 7 and 14, months 1, 2, 3, and 6. Women completed stress and depression surveys and provided blood for pro- (IL-1β, IL-6, IL-8, TNF-a, IFN-γ) and anti-inflammatory (IL-10) cytokines, and collected saliva for diurnal cortisol. Self-report of predominant breastfeeding during 6 months postpartum ranged from 91.9% at day 7 to 70.6% at month 6 postpartum. There were no associations between the pattern of feeding and depressive symptoms. Biological differences, however, existed between the groups, with levels of salivary cortisol at 8 AM and 8:30 AM at month 6 higher and levels of IL-6 at month 6 lower in women who primarily breastfed compared to those who primarily bottle fed their infants after controlling for confounding variables. Breastfeeding was not related to postpartum depression however differences in stress and inflammatory markers are apparent at month 6 postpartum. Copyright © 2015 Elsevier Ltd. All rights reserved.

Ingroup perception or the views people with depression have about their group, may influence their vulnerability to social identity threat and lead to enhanced stress reactions and impaired performance. It is unclear how ingroup perception can influence stress appraisals in performance situations among people with a history of depression who are currently in remission. We investigated the impact of ingroup perception on primary stress appraisal, i.e. how threatening a test situation is perceived, as well as on secondary stress appraisal, or perceived coping resources. Sixty people with a history of depression and currently in remission underwent computerized performance tests. Ingroup perception (group identification, group value and entitativity) and stress appraisals were assessed by self-report. In multiple linear regressions higher group identification predicted stronger perception of the situation as stressful if participants perceived people with depression as a coherent group (high entitativity) and held this group in low regard (low group value). In turn, stronger group identification was related to more perceived coping resources especially if participants did not regard people with depression as a coherent group. Our findings highlight the relevance of ingroup perception for stress and coping processes in people with a history of depression. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

Hypoxic exposure results in several pathophysiological conditions associated with nervous system, these include acute and chronic mountain sickness, loss of memory, and high altitude cerebral edema. Previous reports have also suggested the role of hypoxia in pathogenesis of depression and related psychological conditions. On the other hand, sub lethal intermittent hypoxic exposure induces protection against future lethal hypoxia and may have beneficial effect. Therefore, the present study was designed to explore the neuroprotective role of intermittent hypobaric hypoxia (IHH) in Unpredictable Chronic Mild Stress (UCMS) induced depression like behaviour in rats. The IHH refers to the periodic exposures to hypoxic conditions interrupted by the normoxic or lesser hypoxic conditions. The current study examines the effect of IHH against UCMS induced depression, using elevated plus maze (EPM), open field test (OFT), force swim test (FST), as behavioural paradigm and related histological and molecular approaches. The data indicated the UCMS induced depression like behaviour as evident from decreased exploration activity in OFT with increased anxiety levels in EPM, and increased immobility time in the FST; whereas on providing the IHH (5000m altitude, 4hrs/day for two weeks) these behavioural changes were ameliorated. The morphological and molecular studies also validated the neuroprotective effect of IHH against UCMS induced neuronal loss and decreased neurogenesis. Here, we also explored the role of Brain-Derived Neurotrophic Factor (BDNF) in anticipatory action of IHH against detrimental effect of UCMS as upon blocking of BDNF-TrkB signalling the beneficial effect of IHH was nullified. Taken together, the findings of our study demonstrate that the intermittent hypoxia has a therapeutic potential similar to an antidepressant in animal model of depression and could be developed as a preventive therapeutic option against this pathophysiological state.

in serum by immunoassay and independent determinants of the serum VEGF level were assessed by generalized linear models.The main findings were that depression, severity of depression, previous depressive episodes, age and body mass index (BMI) were associated with higher serum VEGF levels. The genetic...... marker rs10434 was significantly associated with depression after correction for multiple testing, but not with the serum VEGF level. Our final model included depression and BMI as predictors of serum VEGF levels. Our study suggests a role for circulating serum VEGF in depression. Furthermore, our data...
