    2011-01-01

    Background Falls are one of the main causes of fractures in elderly people and after a recent fracture, the risk of another fall is increased, resulting in subsequent fracture. Therefore, risk factors for future falls should be determined. We prospectively investigated the relationship between depression and the incidence of falls in post-menopausal women after a low-energy fracture. Methods At baseline, 181 women aged 60 years and older who presented with a recent low-energy fracture were evaluated at the fracture and osteoporosis outpatient clinics of two hospitals. As well as clinical evaluation and bone mineral density tests, the presence of depression (measured using the Edinburgh Depression Scale, EDS, depression cut-off > 11) and risk factors for falling were assessed. During two years of follow-up, the incidence of falls was registered annually by means of detailed questionnaires and interviews. Results Seventy-nine (44%) of the women sustained at least one fall during follow-up. Of these, 28% (n = 22) suffered from depression at baseline compared to 10% (n = 10) of the 102 women who did not sustain a fall during follow-up (Χ2 = 8.76, df = 1, p = .003). Multiple logistic regression showed that the presence of depression and co-morbidity at baseline were independently related to falls (OR = 4.13, 95% CI = 1.58-10.80; OR = 2.25, 95% CI = 1.11-4.56, respectively) during follow-up. Conclusions The presence of depression in women aged 60 years and older with recent low-energy fractures is an important risk factor for future falls. We propose that clinicians treating patients with recent low-energy fractures should anticipate not only on skeletal-related risk factors for fractures, but also on fall-related risk factors including depression.

    Full Text Available Until present no data was available inArmeniain respect of incidence of low energy fractures that are typical of osteoporotic locations which consequently did not allow to evaluate the scope of this problem across the country.Purpose of the study – to identify the incidence of low energy fractures in proximal femur, in distal forearm, in proximal humerus and in distal tibia across population ofArmenia aged 50 years and older.Materials and methods. An observing population study was performed in two regions of Armenia during 2011-2013 where the frequency of selected locations in cases of moderate trauma was identified. During 2011-2012 the information was collected based on traumatology service records adding in 2013 other sources including primary level of healthcare due to observed infrequent applications for medical help in cases of trauma. Results. In 2013 the incidence of proximal femur fractures in men was reported as 136 cases per 100 000 of population aged 50 years and older, in women – 201 cases per 100 000. At the same time only 57.7% of patients with proximal femur fractures were admitted to hospital. Distal forearm fractures incidence in men and women was observed correspondingly 56/100 000 and 176/100 000 cases, proximal humerus fractures – 39/100 000 and 86/100 000 cases and distal tibia fractures – 39/100 000 and 86/100 000 cases. The predicted annual number of proximal femur fracture in Armenia amounts to 2067 cases, distal forearm fractures – 1205, proximal humerus fractures – 640.Conclusion. Epidemiological data that was collected for the first time on low energy fractures incidence confirmed the acute osteoporosis issue inArmenia and revealed the problems in organization of medical care for the group of senior patients with injuries.

    Full Text Available Stress is critically involved in the development and progression of disease. From the stress of undergoing treatments to facing your own mortality, the physiological processes that stress drives have a serious detrimental effect on the ability to heal, cope and maintain a positive quality of life. This is becoming increasingly clear in the case of neurodegenerative diseases. Neurodegenerative diseases involve the devastating loss of cognitive and motor function which is stressful in itself, but can also disrupt neural circuits that mediate stress responses. Disrupting these circuits produces aberrant emotional and aggressive behavior that causes long-term care to be especially difficult. In addition, added stress drives progression of the disease and can exacerbate symptoms. In this review, I describe how neural and endocrine pathways activated by stress interact with ongoing neurodegenerative disease from both a clinical and experimental perspective.

    We explored the prospective, microlevel relationship between nightly sleep quality (SQ) and the subsequent day's stress on positive (PA) and negative affect (NA) as well as the moderating relationships between nightly SQ, subsequent stress, and subsequent PA on NA. We investigated whether age moderated these relationships. We collected 56 days of sleep, stress, and affect data using daily diary questionnaires (N = 552). We used multilevel modeling to assess relationships at the between- and within-person levels. Daily increases in SQ and decreases in stress interacted to predict higher daily PA and lower daily NA. Better SQ in older adults enhanced the benefits of PA on the stress-NA relationship more during times of low stress, whereas better sleep in younger adults enhanced the benefits of PA more during times of high stress. Between-person effects were stronger predictors of well-being outcomes than within-person variability. The combination of good SQ and higher PA buffered the impact of stress on NA. The moderating impact of age suggests that sleep and stress play different roles across adulthood. Targeting intervention and prevention strategies to improve SQ and enhance PA could disrupt the detrimental relationship between daily stress and NA. © The Author 2015.

Occupational stress measured among a total of 498 workers of a shipbuilding firm who visited the hospital for health examination using the Korean Occupational Stress Scale (KOSS)-short form, and the relationship between sociodemographic factors, health-related behaviors, occupational stress, and gastric disease, and the distribution of occupational stress by sociodemographic factors in the gastric disease group was examined. There was no significant association between gastric disease and total occupational stress score and its seven sub-factors. The analysis showed that risk of gastric disease was significantly higher in the Q1 group in which the stress caused by occupational discomfort among seven sub-factors was lowest than that in the Q4 group (odds ratio, 2.819; 95% confidence interval, 1.151 to 6.908). Analysis only on the gastric disease group showed that the stress score of laborers was higher in the four sub-factors than that of office workers (P occupational stress in the low-educated and laborers. It is recommended for future studies to confirm the causal relationship between occupational stress and gastric disease by large scale studies using a KOSS which appropriately reflects workplace culture.

    Pineal hormone and thyroid functions, were studied simultaneously in rats after the induction of acute psychic stress as well as exogenous administration of melatonin, thyroxine and also after thyroidectomy. A gradual increase in 131 I uptake, serum PBI and melatonin levels were observed in blood, reaching maximum on 8th day of psychic stress. Melatonin administration resulted in hypothyroidism whereas thyroxine increased the activity of pineal qland. Thyroidectomy revealed a gradual decrease in melatonin content of pineal gland whereas supplementation with thyroxine resulted in a melatonin content similar to that observed in sham operated (control) group.

    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.

  2. The momentary relationship between stress and headaches in adolescent girls.

    2009-09-01

    The objective of this study was to compare the relationship between repeated momentary reports of stress and headaches in female adolescents with varying degrees of headache frequency. Headaches are the most common form of pain reported by adolescents affecting more than a third of all adolescents. High levels of stress during adolescence may predispose an adolescent to experience headaches in adulthood. Randomized, momentary data collection of stress and headaches provides the most accurate data regarding the adolescent experience of these variables. The research methodology, ecological momentary assessment, is a valid approach to better understand the relationship between stress and headaches in adolescence. Data were obtained by each participant's use of an electronic diary (ED), which captured repeated momentary reports of perceived stress, head pain, and stress-related symptoms in female adolescents with varying degrees of recurrent headache. Seven times per day for the 21-day study period, teen girls responded to ED questions about their current stress levels, head pain, and stress-related symptoms. Based on participants' momentary reports of headaches, Low Headache, Moderate Headache, and Chronic Headache groups were created. General estimating equation models were used to analyze the relationship between momentary variables as well as the lag effect between stress and head pain. Thirty-one participants, aged 14-18 years, completed 2841 randomized ED reports and reported 674 occurrences of headache. The Chronic Headache and Moderate Headache groups reported significantly increased levels of stress, head pain, and headaches. The relationship between momentary stress and head pain was significantly strong both within and across participants. The strength of this relationship increased with increased headache activity. A significant lag effect was found between stress and headaches; however, the effect of depression as a moderator of the stress and headache

    Stress is a concept that has received increased attention in marital research during the last decade, showing that it plays an important role in understanding the quality and stability of close relationships. Evidence suggests that stress is a threat to marital satisfaction and its longevity. Research has been based upon theoretical models of stress in close relationships, specifically family stress models [e.g., Hill, R. (1958). Generic features of families under stress. Social Casework, 39, 139-150.; McCubbin, H. I., & Patterson, J. M. (1983). Family transitions: Adaptation to stress. In H. I. McCubbin & C. R. Figley (Eds.), Stress and the family: Coping with normative transitions (Vol. 2, pp. 5-25). New York: Brunner/Mazel] and couple's stress model's proposed by Karney, Story, and Bradbury [Karney, B. R., Story, L. B., & Bradbury, T. N. (2005). Marriages in context: Interactions between chronic an acute stress among newlyweds. In T. A. Revenson, K. Kayser, & G. Bodenmann (Eds.), Couples coping with stress: Emerging perspectives on dyadic coping (pp.13-32). American Psychological Association: Washington, D.C.] and Bodenmann [Bodenmann, G. (1995). A systemic-transactional conceptualization of stress and coping in couples. Swiss Journal of Psychology, 54, 34-49.; Bodenmann, G. (2005). Dyadic coping and its significant for marital functioning. In T. Revenson, K. Kayser, & G. Bodenmann (Eds.), Couples coping with stress: Emerging perspectives on dyadic coping (pp.33-50). American Psychological Association: Washington, D.C.]. In this review we: (1) examine the various theoretical models of stress, (2) analyze and summarize the typologies relating to stress models (internal versus external, major versus minor, acute versus chronic), and (3) summarize findings from stress research in couples that has practical significance and may inspire clinical work. Future directions in research and clincial significance are suggested.

  4. Polyamines and abiotic stress in plants: A complex relationship

    Full Text Available The physiological relationship between abiotic stress in plants and polyamines was reported more than 40 years ago. Ever since there has been a debate as to whether increased polyamines protect plants against abiotic stress (e.g. due to their ability to deal with oxidative radicals or cause damage to them (perhaps due to hydrogen peroxide produced by their catabolism. The observation that cellular polyamines are typically elevated in plants under both short-term as well as long-term abiotic stress conditions is consistent with the possibility of their dual effects, i.e. being a protector as well as a perpetrator of stress damage to the cells. The observed increase in tolerance of plants to abiotic stress when their cellular contents are elevated by either exogenous treatment with polyamines or through genetic engineering with genes encoding polyamine biosynthetic enzymes is indicative of a protective role for them. However, through their catabolic production of hydrogen peroxide and acrolein, both strong oxidizers, they can potentially be the cause of cellular harm during stress. In fact, somewhat enigmatic but strong positive relationship between abiotic stress and foliar polyamines has been proposed as a potential biochemical marker of persistent environmental stress in forest trees in which phenotypic symptoms of stress are not yet visible. Such markers may help forewarn forest managers to undertake amelioration strategies before the appearance of visual symptoms of stress and damage at which stage it is often too late for implementing strategies for stress remediation and reversal of damage. This review provides a comprehensive and critical evaluation of the published literature on interactions between abiotic stress and polyamines in plants, and examines the experimental strategies used to understand the functional significance of this relationship with the aim of improving plant productivity, especially under conditions of abiotic stress.

    This bibliographic review aimed to differentiate between stress and Burnout and to establish their relationship with nursing work to support the understanding of psychical suffering at work. The study was based on the analysis and interpretation of articles, thesis and dissertations produced between 1990 and 2001. Although there is a consensus among the individuals on the existence of stress and burnout, there are several controversies surrounding these terms. These theories were created in the context of capitalist production increase. Stress refers to a personal tiring that interferes in the life of the person but not necessarily in his/her relationship with the work. Burnout is a syndrome involving negative attitudes and behaviors towards users, clients, organization and work. It is a gradual process of subjective experiences that result in practical and emotional problems to workers and organizations. Nursing work facilitates stress and burnout and causes suffering and illness among workers.

    Stressful life events and daily life stresses have both deleterious and cumulative effects on human body. In several studies, stress has been shown to affect various parameter of higher mental function like attention, concentration, learning and memory. Present study was designed to explore the relationship among GI level, EI level, psychological stress levels and acute stress reactivity in young normal healthy subjects. The study was conducted on thirty four healthy male student volunteers to study a) acute stress reactivity in subjects with varying levels of General Intelligence (GI) and Emotional Intelligence (EI) and b) correlation between GI, EI, acute stress and perceived stress. Baseline GI and EI and acute stress and perceived stress scores were measured by standard assessment scales. Using median value of GI and EI scores as cutoff values, subjects were categorized into four groups. Among different GI-EI groups, acute stress reactivity was similar but salivary Cortisol (especially post stressor level) and perceived stress level was a differentiating factor. High level of EI was associated inversely with acute and chronic perceived stress level. Significant correlation was found between acute and chronic perceived stress levels. Level of general intelligence showed no relation to acute or chronic stress levels as well as acute stress reactivity. The differences in various groups of GI and EI had no effect on the baseline and post stress performance on Sternberg memory test and all the three conditions of Stroop test. In conclusion emotional intelligence as an attribute is better suited to handle day to day acute stress and chronic perceived stress.

The negative effects of physical exercise are commonly attributed to an imbalance between the levels of antioxidants (both low molecular weight antioxidants and antioxidant enzymes) and reactive oxygen and nitrogen species due to excessive production of free radicals during physical exercise. In this critical review, we look for answers for three specific questions regarding the interrelationship between physical exercise and oxidative stress (OS), namely, (i) the dependence of the steady-state level of OS on fitness, (ii) the effect of intensive exercise on the OS and (iii) the dependence of the effect of the intense exercise on the individual fitness. All these questions have been raised, investigated and answered, but the answers given on the basis of different studies are different. In the present review, we try to explain the reason(s) for the inconsistencies between the conclusions of different investigations, commonly based on the concentrations of specific biomarkers in body fluids. We think that most of the inconsistencies can be attributed to the difference between the criteria of the ill-defined term denoted OS, the methods used to test them and in some cases, between the qualities of the applied assays. On the basis of our interpretation of the differences between different criteria of OS, we consider possible answers to three well-defined questions. Possible partial answers are given, all of which lend strong support to the conclusion that the network responsible for homeostasis of the redox status is very effective. However, much more data are required to address the association between exercise and OS and its dependence on various relevant factors.

    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.

    Full Text Available Insomnia among workers reduces the quality of life, contributes toward the economic burden of healthcare costs and losses in work performance. The relationship between occupational stress and insomnia has been reported in previous studies, but there has been little attention to temperament in occupational safety and health research. The aim of this study was to clarify the relationships between temperament, occupational stress, and insomnia. The subjects were 133 Japanese daytime local government employees. Temperament was assessed using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Auto questionnaire (TEMPS-A. Occupational stress was assessed using the Generic Job Stress Questionnaire (GJSQ. Insomnia was assessed using the Athens Insomnia Scale (AIS. Stepwise multiple logistic regression analyses were conducted. In a stepwise multivariate logistic regression analysis, it was found that the higher subdivided stress group by "role conflict" (OR = 5.29, 95% CI, 1.61-17.32 and anxious temperament score (OR = 1.33; 95% CI, 1.19-1.49 was associated with the presence of insomnia using an adjusted model, whereas other factors were excluded from the model. The study limitations were the sample size and the fact that only Japanese local government employees were surveyed. This study demonstrated the relationships between workers' anxious temperament, role conflict, and insomnia. Recognizing one's own anxious temperament would lead to self-insight, and the recognition of anxious temperament and reduction of role conflict by their supervisors or coworkers would reduce the prevalence of insomnia among workers in the workplace.

    The worldwide epidemic of metabolic syndromes and the recognized burden of mental health disorders have driven increased research into the relationship between the two. A maladaptive stress response is implicated in both mental health disorders and metabolic disorders, implicating the hypothalamic-pituitary-adrenal (HPA) axis as a key mediator of this relationship. This review explores how an altered energetic state, such as hyper- or hypoglycemia, as may be manifested in obesity or diabetes, affects the stress response and the HPA axis in particular. We propose that changes in energetic state or energetic demands can result in "energetic stress" that can, if prolonged, lead to a dysfunctional stress response. In this review, we summarize the role of the hypothalamus in modulating energy homeostasis and then briefly discuss the relationship between metabolism and stress-induced activation of the HPA axis. Next, we examine seven mechanisms whereby energetic stress interacts with neuroendocrine stress response systems, including by glucocorticoid signaling both within and beyond the HPA axis; by nutrient-induced changes in glucocorticoid signaling; by impacting the sympathetic nervous system; through changes in other neuroendocrine factors; by inducing inflammatory changes; and by altering the gut-brain axis. Recognizing these effects of energetic stress can drive novel therapies and prevention strategies for mental health disorders, including dietary intervention, probiotics, and even fecal transplant.

    Full Text Available Regardless of where one lives in the world, one cannot escape three defi ning forces of our time: globalisation, the information revolution and the speed of change (Cascio, 2001. To ensure continued organisational performance and to maintain the competitive advantage, organisations must therefore constantly implement changes in strategy, structure, process and culture (Higgs, 2002; Langley, 2000. Goleman (1998 proposes a solution of self-awareness as a key skill in handling stress, thereby indicating that a lack of emotional intelligence in such an unstable environment means possible failure that can impact on everyone’s future. The general aim of this research was to determine whether there is a relationship between emotional intelligence and stress management in a group of managers. This was done through a quantitative study of the relationship between stress management and emotional intelligence. These constructs were operationalised by means of a combination of scales present in the Feelings and Emotions domain of the Occupational Personality Questionnaire (OPQ32i and the Emotional Quotient Inventory (Bar-On EQ-i. The correlation and regression results seem to indicate that stress management (the ability to cope with stress is a component of emotional intelligence, while stress can be either an input or an outflow of emotional intelligence or the lack thereof.

    The increase in oxidative stress that accompanies aging has been implicated in the abnormal advance of aging and in the onset of various systemic diseases. However, the details of what effects the increase in oxidative stress that accompanies aging has on saliva secretion are not known. In this study, naturally aging mice were used to examine the stimulated whole saliva flow rate, saliva and serum oxidative stress, antioxidant level, submandibular gland H-E staining, and immunofluorescence staining to investigate the effect of aging on the volume of saliva secretion and the relationship with oxidative stress, as well as the effect of aging on the structure of salivary gland tissue. The stimulated whole saliva flow rate decreased significantly with age. Also, oxidative stress increased significantly with age. Antioxidant levels, however, decreased significantly with age. Structural changes of the submandibular gland accompanying aging included atrophy of parenchyma cells and fatty degeneration and fibrosis of stroma, and the submandibular gland weight ratio decreased. These results suggest that oxidative stress increases with age, not just systemically but also locally in the submandibular gland, and that oxidative stress causes changes in the structure of the salivary gland and is involved in hyposalivation.

    Burnout represents a critical disruption in an individual's relationship with work, resulting in a state of exhaustion in which one's occupational value and capacity to perform are questioned. Burnout can negatively affect an individual's personal life, as well as employers in terms of decreased work quality, patient/client satisfaction, and employee retention. Occupational stress is a known contributor to burnout and occurs as a result of employment requirements and factors intrinsic to the work environment. Empirical research examining genetic counselor-specific burnout is limited; however, existing data suggests that genetic counselors are at increased risk for burnout. To investigate the relationship between occupational stress and burnout in genetic counselors, we administered an online survey to members of three genetic counselor professional organizations. Validated measures included the Maslach Burnout Inventory-General Survey (an instrument measuring burnout on three subscales: exhaustion, cynicism, and professional efficacy) and the Occupational Stress Inventory-Revised (an instrument measuring occupational stress on 14 subscales). Of the 353 respondents, more than 40 % had either considered leaving or left their job role due to burnout. Multiple regression analysis yielded significant predictors for burnout risk. The identified sets of predictors account for approximately 59 % of the variance in exhaustion, 58 % of the variance in cynicism, and 43 % of the variance in professional efficacy. Our data confirm that a significant number of genetic counselors experience burnout and that burnout is correlated with specific aspects of occupational stress. Based on these findings, practice and research recommendations are presented.

    Background: Occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. Recently, staff network of different government universities of Thailand have called higher education commission, and Ministry of Education, Thailand to resolve the issue of government education policy (e.g. wage inequity, poor welfare, law, and job & environment condition) that leads to their job insecurity, physical and mental health problems from occupational stress. The aim of this study was to investigate a causal relationship of occupational stress among the academic university employees. Methods: This cross sectional research was conducted in 2014 among 2,000 academic university employees at Thai government universities using stratified random sampling. Independent variables were wage, family support, periods of duty, and job & environmental condition. Dependent variable was stress. Results: Job & environmental condition, as social and environmental factor, and periods of duty as individual factor had direct effect to stress (Pstress (P stress among academic university employees at moderate level.

    Full Text Available This study develops a simple and rational shear stress-relative slip model of concrete interfaces with monolithic castings or smooth construction joints. In developing the model, the initial shear cracking stress and relative slip amount at peak stress were formulated from a nonlinear regression analysis using test data for push-off specimens. The shear friction strength was determined from the generalized equations on the basis of the upper-bound theorem of concrete plasticity. Then, a parametric fitting analysis was performed to derive equations for the key parameters determining the shapes of the ascending and descending branches of the shear stress-relative slip curve. The comparisons of predictions and measurements obtained from push-off tests confirmed that the proposed model provides superior accuracy in predicting the shear stress-relative slip relationship of interfacial shear planes. This was evidenced by the lower normalized root mean square error than those in Xu et al.’s model and the CEB-FIB model, which have many limitations in terms of the roughness of the substrate surface along an interface and the magnitude of equivalent normal stress.

    Vigilant coping is characterized by a deep processing of threat-related information. In many cases, vigilant coping increases stress symptoms, whereas avoidant coping decreases negative affect. However, vigilance may be beneficial when stress-eliciting situations involve a risk of injury or escalation as is usually the case in police operations. We investigated the roles of vigilance and cognitive avoidance in police operations in a cross-sectional survey. The participants were 137 students (104 men, M age  = 28.54, SD = 8.04) from the Federal University of Applied Administrative Sciences; 76 of them were already police officers (work experience: M = 12.59 years), and 61 were police officer candidates who had completed a 3- to 6-month police internship. Participants completed a paper-and-pencil survey and reported their operational stress, dispositional vigilance and cognitive avoidance in police operations, and stress symptoms. We found that vigilance was negatively associated with stress symptoms and moderated the relationship between operational stress and stress symptoms. Cognitive avoidance, on the other hand, just missed the level of statistical significance in our test of whether it was positively associated with stress symptoms. Our findings demonstrate that vigilance may protect against the negative consequences of stress in police operations.

    Allergic rhinitis is considered to be a major health problem that impairs quality of life. A possible relationship with psychological stress may exist. The aim of this study is to verify the relationship between persistent allergic rhinitis (PAR) and psychological stress aiming to improve treatment and thereby quality of life (QOL) of patients. Patients with PAR (166) were diagnosed then analyzed using the Kessler Psychological Distress Scale. Patients with allergic rhinitis and who were positive on the Kessler scale (122) were randomly divided equally into a control group which received levocetirizine and a study group which received levocetirizine and imipramine. Nasal symptom assessment and QOL assessment were performed in all patients after treatment. Of the 166 patients with PAR, 122 (73.5 %) were positive on the Kessler Psychological Distress Scale. There was a marked improvement in the study group compared with the control group as regards nasal symptoms with better QOL in the study group (6.93) compared with the control group (2.13). Psychological stress has a strong impact on persistent allergic rhinitis. When stress is controlled by a combined treatment of imipramine and levocetirizine, allergic rhinitis symptoms improved and a better QOL was obtained. 3b.

    Full Text Available Many empirical confinement models for normal and high strength concrete have been developed. Nevertheless, reported studies in the term of confinement of fiber reinforced concrete are limited. Whereas, the use of fiber reinforced concrete in structural elements has become the subject of the research and has indicated positive experiences. Since the stress-strain relationship of concrete in compression is required for analysis of structural members, the study of the stress-strain relationship for synthetic fiber reinforced concrete is substantial. The aim of the study is to examine the capabilities of the various models available in the literature to predict the actual experimental behavior of synthetic fiber reinforced high-strength concrete columns. The experimental data used are the results of the circular column specimens with the spiral spacing and the volume fraction of synthetic fiber as the test variables. The axial stress-strain curves from the tests are then compared with the various models of confinement from the literature. The performance index of each model is measured by using the coefficient of variation (COV concept of stress and strain behavior parameter. Among the confinement models, Cusson model shows the closest valid value of the coefficient of variation.

    This study was performed to investigate the relationship between the injured lateral ankle ligaments on MRI and stress ankle radiographs. Two hundred and twenty-nine consecutive patients (mean age 35.5 years, SD 14.6 years; 136 males and 93 females) that underwent ankle stress radiographs and MRI for lateral ankle instability were included. Tibiotalar tilt angle and anterior translation of talus were measured on stress ankle radiographs. Degree of lateral ligaments (anterior talofibular, calcaneofibular, and posterior talofibular) and deltoid ligament injuries were evaluated and scored as intact (0), partial injury (1), and complete injury (2) on MR images. Effusion of ankle joint was also recorded. The effects of gender, age, injuries of ligaments, and ankle joint effusion on stress radiographs were statistically analyzed. Gender (p = 0.010), age (p = 0.020), and anterior talofibular ligament (ATFL) injury (p < 0.001) were the factors significantly affecting tibiotalar tilt angle. Posterior talofibular ligament (PTFL) injury (p = 0.014) was found to be the only significant factor affecting the anterior translation on the anterior drawer radiographs. ATFL injury and PTFL injury on MRI significantly affected tibiotalar tilt angle and anterior drawer on stress radiographs. Other factors, such as age and gender, need to be considered in evaluating radiographic lateral ankle instability. (orig.)

    The purpose of this study was to examine the relationship between stress coping and burnout in Japanese hospital nurses. Findings on effective stress management training are required in order to reduce nurse's stress and prevent it from becoming chronic. The study included 1291 nurses who completed the General Coping Questionnaire and the Japanese version of the Maslach Burnout Inventory-General Survey. The data were analysed using structural equation modelling. In women, a frequent use of cognitive reinterpretation predicted low exhaustion and cynicism and high professional efficacy. In men, a frequent use of problem solving predicted low cynicism and high professional efficacy. Although for women, a frequent use of problem solving predicted high professional efficacy that was similar to men, there was also a concurrent high exhaustion. These findings suggested that enhancement of cognitive coping skills for women and problem-solving skills for men could contribute to a reduction of burnout in nurses. Our findings suggested that effective intervention strategies in order to prevent hospital nurse's stress from becoming chronic might be different between men and women. This difference should be taken into account in nursing management.

Methods In April 2008, 272 submariners trained in a navy base were selected as study subjects by random group sampling method, and tested by primary personal information questionnaire, self-rated health measurement scale (SRHMS, self-developed submariners' work stressors questionnaire, and work stress self-rated scale. Physical health, mental health and social health of submariners were analyzed, and scores were compared with the norm of reference scores. Correlations were analyzed respectively between 10 items of submariners' general information (including age, length of military service, education degree, years at the present post, times of receiving awards, on-duty hours, off-duty hours, hours of sleep, lost days of leave, positive attitude to work and their physical health score, mental health score, social health score, total health score, as well as between 15 submariners' work stressors (including workrelated risks, diet problems, high temperature, humidity and noise in workplace, shortage of clean clothes, illness, losing contact with outside, lack of information about the task, lacking supports from family members, relationship problems, lack of involvement in task decisions, boring and dull work, on duty, heavy work, high quality of work, coping with unexpected threat and their physical health score, mental health score, social health score and total health score. Results No significant difference was found between submariners' SRHMS total score and the normal referenced score (t=0.56, P>0.05, but the physical health score and mental health score were significantly lower than normal referenced scores respectively (t=–2.172, P<0.05; t=–3.299, P<0.01, and the social health score was significantly higher than normal referenced score (t=9.331, P<0.001.

    Coping, the cognitive and behavioral effort required to manage the effects of stressors, is important in determining psychological stress responses (ie, the emotional, behavioral, and cognitive responses to stressors). Coping was classified into categories of emotional expression (eg, negative feelings and thoughts), emotional support seeking (eg, approaching loved ones to request encouragement), cognitive reinterpretation (eg, reframing a problem positively), and problem solving (eg, working to solve the problem). Stress mindset refers to the belief that stress has enhancing (stress-is-enhancing mindset) or debilitating consequences (stress-is-debilitating mindset). This study examined whether coping mediated the relationship between stress mindset and psychological stress responses. Psychological stress responses were conceptualized as depression-anxiety, irritability-anger, and helplessness. The following two hypotheses were tested: 1) a stronger stress-is-enhancing mindset is associated with less frequent use of emotional expression, emotional support seeking, and problem solving, which in turn is associated with lower levels of depression-anxiety, irritability-anger, and helplessness; 2) a stronger stress-is-debilitating mindset is associated with more frequent use of these coping strategies, which in turn is associated with higher levels of these psychological stress responses. The participants were 30 male and 94 female undergraduate and graduate students (mean age =20.4 years). Stress mindset, coping, and psychological stress responses were measured using self-report questionnaires. Six mediation analyses were performed with stress-is-enhancing mindset or stress-is-debilitating mindset as the independent variable, one of the psychological stress responses as the dependent variable, and the four coping strategies as mediators. Emotional expression partially mediated the relationship between a strong stress-is-debilitating mindset and higher irritability

    Full Text Available Four hundred and two R&D personnel were surveyed through questionnaires to study the relationship between mental toughness, stress appraisal (including experience of stress and stress control, and innovation performance. The findings reveal a significant negative correlation between mental toughness and stress experience and a significant positive correlation between mental toughness and both stress control and innovation performance. Furthermore, although the experience of stress was negatively correlated with innovation performance, stress control had the opposite effect. Experience of stress and stress control were the mediating variables for mental toughness and innovation performance, respectively. There was also a significant interaction effect between stress appraisal and mental toughness.

    Full Text Available Metabolic syndrome (MS represents a cluster of physiological and anthropometric abnormalities. The purpose of this study was to investigate the relationships between the levels of inflammation, adiponectin, and oxidative stress in subjects with MS. The inclusion criteria for MS, according to the Taiwan Bureau of Health Promotion, Department of Health, were applied to the case group (n = 72. The control group (n = 105 comprised healthy individuals with normal blood biochemical values. The levels of inflammatory markers [high sensitivity C-reactive protein (hs-CRP and interleukin-6 (IL-6, adiponectin, an oxidative stress marker (malondialdehyde, and antioxidant enzymes activities [catalase (CAT, superoxide dismutase (SOD, and glutathione peroxidase (GPx] were measured. Subjects with MS had significantly higher concentrations of inflammatory markers and lower adiponectin level, and lower antioxidant enzymes activities than the control subjects. The levels of inflammatory markers and adiponectin were significantly correlated with the components of MS. The level of hs-CRP was significantly correlated with the oxidative stress marker. The IL-6 level was significantly correlated with the SOD and GPx activities, and the adiponectin level was significantly correlated with the GPx activity. A higher level of hs-CRP (≥1.00 mg/L, or IL-6 (≥1.50 pg/mL or a lower level of adiponectin (<7.90 µg/mL were associated with a significantly greater risk of MS. In conclusion, subjects suffering from MS may have a higher inflammation status and a higher level of oxidative stress. A higher inflammation status was significantly correlated with decreases in the levels of antioxidant enzymes and adiponectin and an increase in the risk of MS.

    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.

    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.

    This paper examines the association between relationship stress and sexual dysfunction. The results demonstrated a strong association between female sexual dysfunction (FSD) and relationship stress, and between male sexual dysfunction (MSD) and relationship stress among their female partners. No studies examined the association between FSD and relationship stress of male partners. Treatment for MSD was associated with improved relationship stress for female partners, but no studies were located that examined this association for treatment of FSD. These findings suggest that FSD and relationship stress are strongly related, but the association does not seem to be so strong for men. The review highlights the need for further research in this field to inform therapy for both sexual dysfunction and relationship problems. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To maintain a stable intracellular environment, cells utilize complex and specialized defense systems against a variety of external perturbations, such as electrophilic stress, heat shock, and hypoxia, etc. Irrespective of the type of stress, many adaptive mechanisms contributing to cellular homeostasis appear to operate through gene regulatory networks that are organized into negative feedback loops. In general, the degree of deviation of the controlled variables, such as electrophiles, misfolded proteins, and O2, is first detected by specialized sensor molecules, then the signal is transduced to specific transcription factors. Transcription factors can regulate the expression of a suite of anti-stress genes, many of which encode enzymes functioning to counteract the perturbed variables. The objective of this study was to explore, using control theory and computational approaches, the theoretical basis that underlies the steady-state dose response relationship between cellular stressors and intracellular biochemical species (controlled variables, transcription factors, and gene products) in these gene regulatory networks. Our work indicated that the shape of dose response curves (linear, superlinear, or sublinear) depends on changes in the specific values of local response coefficients (gains) distributed in the feedback loop. Multimerization of anti-stress enzymes and transcription factors into homodimers, homotrimers, or even higher-order multimers, play a significant role in maintaining robust homeostasis. Moreover, our simulation noted that dose response curves for the controlled variables can transition sequentially through four distinct phases as stressor level increases: initial superlinear with lesser control, superlinear more highly controlled, linear uncontrolled, and sublinear catastrophic. Each phase relies on specific gain-changing events that come into play as stressor level increases. The low-dose region is intrinsically nonlinear, and depending on

    Little attention has been focused on stress levels of parents of children with cochlear implants (CIs). This study examined the stress experience of 70 parents of children with CIs by comparing stress levels in this group of parents to those in parents of children without disabilities, identifying primary stressors, examining the relationship between parent stress and child language, and comparing stress in parents of children with bilateral and unilateral CIs. Parents completed a parent stress questionnaire, and the receptive vocabulary and language abilities of the children were evaluated. Results indicated that these parents had a higher incidence of stress than the normative population. Parent stress levels and child language outcomes were negatively correlated. Child behavior and lack of spousal and social support were the prime causes of parent stress. Parents of children with bilateral CIs were significantly less stressed than were parents of children with unilateral CIs.

    As many countries around the world face an aging infrastructure crisis, there is an increasing need to develop more accurate monitoring and assessment techniques for reinforced concrete structures. One of the challenges associated with assessing existing infrastructure is correlating externally measured parameters such as crack widths and surface strains with reinforcement stresses as this is dependent on a number of variables. The current research investigates how the use of distributed fiber optic sensors to measure reinforcement strain can be correlated with digital image correlation measurements of crack widths to relate external crack width measurements to reinforcement stresses. An initial set of experiments was undertaken involving a series of small-scale beam specimens tested in three-point bending with variable reinforcement properties. Relationships between crack widths and internal reinforcement strains were observed including that both the diameter and number of bars affected the measured maximum strain and crack width. A model that uses measured crack width to estimate reinforcement strain was presented and compared to the experimental results. The model was found to provide accurate estimates of load carrying capacity for a given crack width, however, the model was potentially less accurate when crack widths were used to estimate the experimental reinforcement strains. The need for more experimental data to validate the conclusions of this research was also highlighted.

    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.

    The present study examined the relationship between personality traits and the response to acute psychological stress induced by a standardized laboratory stress induction procedure (the Trier Social Stress Test, TSST). The stress response was measured with a combination of cardiovascular reactivity, hypothalamic-pituitary-adrenal axis reactivity, and subjective affect (including positive affect, negative affect and subjective controllability) in healthy individuals. The Generalized Estimating Equations (GEE) approach was applied to account for the relationship between personality traits and stress responses. Results suggested that higher neuroticism predicted lower heart rate stress reactivity, lower cortisol stress response, more decline of positive affect and lower subjective controllability. Individuals higher in extraversion showed smaller cortisol activation to stress and less increase of negative affect. In addition, higher openness score was associated with lower cortisol stress response. These findings elucidate that neuroticism, extraversion and openness are important variables associated with the stress response and different dimensions of personality trait are associated with different aspects of the stress response.

    Fault permeability is known to depend strongly on stress and fluid pressures. Exponential relationships between permeability and effective pressure have been proposed to approximate fault response to fluid pressure variations. However, the applicability of these largely empirical laws remains questionable, as they do not take into account shear stress and shear strain. A series of experiments using mHPP probes have been performed within fault zones in very low permeability (less than 10-19 m2) Lower Jurassic shale formations at Tournemire (France) and Mont Terri (Switzerland) underground laboratories. These probes allow to monitor 3D displacement between two points anchored to the borehole walls at the same time as fluid pressure and flow rate. In addition, in the Mont-Terri experiment, passive pressure sensors were installed in observation boreholes. Fracture transmissivity was estimated from single borehole pulse test, constant pressure injection tests, and cross-hole tests. It is found that the transmissivity-pressure dependency can be approximated with an exponential law, but only above a pressure threshold that we call the Fracture Opening Threshold (F.O.P). The displacement data show a change of the mechanical response across the F.O.P. The displacement below the F.O.P. is dominated by borehole response, which is mostly elastic. Above F.O.P., the poro-elasto-plastic response of the fractures dominates. Stress determinations based on previous work and on the analysis of slip data from mHPPP probe indicate that the F.O.P. is lower than the least principal stress. Below the F.O.P., uncemented fractures retain some permeability, as pulse tests performed at low pressures yield diffusivities in the range 10-2 to 10-5 m2/s. Overall, this dual behavior appears consistent with the results of CORK experiments performed in accretionary wedge decollements. Results suggest (1) that fault zones become highly permeable when approaching the critical Coulomb threshold (2

Coping was classified into categories of emotional expression (eg, negative feelings and thoughts, emotional support seeking (eg, approaching loved ones to request encouragement, cognitive reinterpretation (eg, reframing a problem positively, and problem solving (eg, working to solve the problem. Stress mindset refers to the belief that stress has enhancing (stress-is-enhancing mindset or debilitating consequences (stress-is-debilitating mindset. This study examined whether coping mediated the relationship between stress mindset and psychological stress responses. Psychological stress responses were conceptualized as depression-anxiety, irritability-anger, and helplessness. The following two hypotheses were tested: 1 a stronger stress-is-enhancing mindset is associated with less frequent use of emotional expression, emotional support seeking, and problem solving, which in turn is associated with lower levels of depression-anxiety, irritability-anger, and helplessness; 2 a stronger stress-is-debilitating mindset is associated with more frequent use of these coping strategies, which in turn is associated with higher levels of these psychological stress responses.

    A relationship between transposable elements (TEs) and the eukaryotic stress response was suggested in the first publications describing TEs. Since then, it has often been assumed that TEs are activated by stress, and that this activation is often beneficial for the organism. In recent years, the availability of new high-throughput experimental techniques has allowed further interrogation of the relationship between TEs and stress. By reviewing the recent literature, we conclude that although there is evidence for a beneficial effect of TE activation under stress conditions, the relationship between TEs and the eukaryotic stress response is quite complex.

    Of all work stressors, occupational stress is the leading cause of many disorders among workers. Drivers are classified as a high risk group for work related stress. This study set out to determine the relationship between risk factors of cardiovascular diseases and occupational stress among drivers. Two hundred and twenty two Ilam's intercity drivers were selected for the study. For measuring work stress, the Osipow work stress questionnaire was used. After a 10-h fasting period, systolic and diastolic blood pressure was recorded. Intravenous blood samples were taken to determine cholesterol, triglyceride and blood glucose levels. The independent samples t-test and Pearson's correlation test were used to assess the relationship between variables and occupational stress. Seventy-one percent of the intercity drivers suffered from average to acute stress, and 3.1% of them suffered from acute stress. There was no significant relationship between occupational stress and diastolic blood pressure (p = 0.254) among the drivers. Nevertheless, the Pearson's correlation test demonstrated a strong relationship between work stress and blood glucose (p stress were observed in the Ilam's intercity drivers. Occupational stress may have effect on blood glucose levels but the results did not suggest a considerable relationship between risk factors of cardiovascular diseases and occupational stress among intercity drivers.

    There is a rich literature on social support and physical health, but research has focused primarily on the protective effects of social relationship. The stress buffering model asserts that relationships may be protective by being a source of support when coping with stress, thereby blunting health relevant physiological responses. Research also indicates relationships can be a source of stress, also influencing health. In other words, the social buffering influence may have a counterpart, a social aggravating influence that has an opposite or opposing effect. Drawing upon existing conceptual models, we expand these to delineate how social relationships may influence stress processes and ultimately health. This review summarizes the existing literature that points to the potential deleterious physiological effects of our relationships when they are sources of stress or exacerbate stress.

    The protracted conflict in Iraq and Afghanistan and an all-volunteer military has resulted in multiple war zone deployments for many service members. While quick redeployment turnaround has left little time for readjustment for either the service member or family, dealing with the long-term sequelae of combat exposure often leaves families and intimate partners ill-prepared for years after deployments. Using a modified grounded theory approach, digitally recorded couple interviews of 23 couples were purposefully selected from a larger sample of 441 couples to better understand the impact of war zone deployment on the couple. The veteran sample was recruited from a randomly selected cohort of men in treatment for posttraumatic stress disorder (PTSD). Overall, it was found when veterans experiencing deployment-related PTSD reenter or start new intimate relationships they may bring with them a unique cluster of interrelated issues which include PTSD symptoms, physical impairment, high rates of alcohol and/or drug abuse, and psychological and physical aggression. These factors contributed to a dynamic of exacerbating conflict. How these couples approached relationship qualities of mutuality, balanced locus of control and weakness tolerance across six axes of caregiving, disability, responsibility, trauma, communication, and community impacted the couple's capacity to communicate and resolve conflict. This dyadic relationship model is used to help inform implications for clinical practice. © 2013 American Association for Marriage and Family Therapy.

    Stressors external to the marriage frequently affect the way spouses evaluate their marital quality. To date, however, understanding of the interplay between external stress and internal relationship processes has been limited in two ways. First, research has generally examined only the short-term consequences of stress. Second, the mechanisms through which external stressors influence relationship outcomes are unclear. This study addressed both limitations by examining relationship cognitions that may mediate the effects of external stress throughout 4 years of marriage. Analyses confirmed that stressful experiences were associated with the trajectory of marital quality overtime. Furthermore, both the content and the organization of spouses' specific relationship cognitions mediated this effect. That is, stress negatively influenced the nature of spouses' marital perceptions as well as the way spouses interpreted and processed those perceptions. These findings draw attention to ways that the context of relationships shapes and constrains relationship processes.

    Subjects with higher occupational position are speculated to have higher ability to handle with stress, and they were less affected by job stress. This study focused on the relationship between job satisfaction and three sub-scales of a brief job stress questionnaire (BJSQ) related to workload. This self-administered questionnaire was distributed to 371 employees of a company, and all the workers sent back their responses. Among the 57 items graded on a 4-point Likert-type scale to measure job stressors, psycho-physical complaints, and support for workers, the authors studied the influence of quantitative and qualitative job overload (six items), job control (three items), and support port (six items). The job satisfaction score estimated on a 4-point Likert-type scale was also used in relation to job stress determined using a 15-item scale from the BJSQ based on demand-control-support model. Occupational positions were classified into directors, managers, and general workers, and the content of job was classified into clerical workers, skilled technicians, and unskilled manual workers. All the scales on job stress presented acceptable alpha coefficients reflecting high internal consistency (job demand: 0.855, job control: 0.644, and support: 0.878, respectively). Principal axis factor analysis was conducted, and three factors were extracted; support, job demand and job control. There was a significant difference in the mean score among four groups divided by the job satisfaction level as evaluated by Dunnett's multiple comparison, and members who were dissatisfied with their job showed a high job demand, limited job control, and poor support. The mean score of support for managers were significantly higher (lower support) than that for general workers. The logistic regression analysis revealed that job control and support contributed significantly to job satisfaction. In addition, unskilled manual workers showed significantly higher job dissatisfaction compared

    Sociability is an essential trait for dogs to successfully interact with humans. In this study, the relationship between sociability and physiological stress was examined. Additionally, whether differences exist between companion dogs (C group) and shelter dogs (S group) was examined. Overall, healthy 37 dogs (C group=21 and S group=16) were examined. After 5 min of walking, the dog and the owner (or the chief manager) rested freely in the experimental location for 5 min. The behavioral test with 6 categories was conducted to evaluate sociability over 4 min. The establishment of two groups (H group=dogs with high sociability; L group=dogs with low sociability) was supported by the statistical results of the behavioral tests. Saliva was collected before (P1) and after the test period (P2), and salivary cortisol levels were determined and statistically analyzed. The cortisol concentrations at P2 and the differences in concentrations between P1 and P2 (P2-P1) in the groups with high sociability were significantly lower than those in the groups with low sociability. These results may demonstrate that sociable dogs adapt more comfortably to strangers and unfamiliar situations. Meanwhile, there were significant differences in hormonal results between the C and S groups. For this reason, their sociability should be evaluated using behavioral and physiological assessments before re-adoption to ensure their successful adaptation.

    Stress mindset theory suggests that positive stress beliefs lead to positive, rather than negative, outcomes when engaging with stressors. Similarly, the Transactional Model of Stress predicts that perceiving a stressor as challenging leads to positive outcomes whereas negative perceptions of the stressor as threatening invoke negative outcomes. The aim of this study was to provide preliminary data examining the nature of the relationship between stress mindset and primary appraisals. It was predicted that positive beliefs about stress would be associated with perceiving a stressful situation as more challenging, and inversely related to perceptions of threat. Participants (N = 124) initially completed measures assessing stress mindset, lifetime and current perceived stress, trait anxiety, and self-efficacy. Then participants received a set of instructions regarding a stressful mathematics task, followed by completion of post-manipulation stress mindset and primary appraisals measures, prior to completing the mathematics task. Multiple linear regression analyses revealed that participants who held a greater number of positive beliefs (as opposed to negative beliefs) about stress also perceived the stressor as being more challenging. However, there was no significant relationship between valence of beliefs and threat appraisals. These findings provide initial evidence for the nature of the relationship between valence of stress beliefs and challenge appraisals. Further research is needed to understand how stress beliefs impact on the way in which an individual copes with stressful situations.

At low stress levels, the acoustoelastic effect and the closure of existing microcracks results in a gradual increase in surface wave...... velocities. At higher stress levels, concrete suffers irrecoverable damage: the existing microcracks widen and coalesce and new microcracks form. This progressive damage process leads first to the flattening and eventually the drop in the velocity-stress curves. Measurements on specimens undergoing several...... loading cycles revealed that the velocities show a stress-memory effect in good agreement with the Kaiser effect. Comparing the velocities measured during loading and unloading, the effects of stress and damage on the measured velocities could be differentiated. Moreover, the stress dependency of surface...

    A central model for chronic tension-type headache (CTH) posits that stress contributes to headache, in part, by aggravating existing hyperalgesia in CTH sufferers. The prediction from this model that pain sensitivity mediates the relationship between stress and headache activity has not yet been examined. To determine whether pain sensitivity mediates the relationship between stress and prospective headache activity in CTH sufferers. Self-reported stress, pain sensitivity and prospective headache activity were measured in 53 CTH sufferers recruited from the general population. Pain sensitivity was modelled as a mediator between stress and headache activity, and tested using a nonparametric bootstrap analysis. Pain sensitivity significantly mediated the relationship between stress and headache intensity. The results of the present study support the central model for CTH, which posits that stress contributes to headache, in part, by aggravating existing hyperalgesia in CTH sufferers. Implications for the mechanisms and treatment of CTH are discussed.

    2015-04-01

    According to the systemic-transactional stress model (STM; G. Bodenmann, European Review of Applied Psychology, 1997; 47: 137), extradyadic stress from daily hassles can have a negative impact on the individual psychological and physical health and the couple's relationship. This study is the first one to test the STM propositions in a model that includes both partners' individual and relational outcomes simultaneously. The model also includes actor and partner effects as well as the interdependence between partners' processes. Cross-sectional, self-report data were collected from 110 community couples in Switzerland. Consistent with STM predictions, results from the path model analysis indicate that for actor effects extradyadic stress from daily hassles relates directly to lower psychological (increase in anxiety symptoms) and physical well-being and only indirectly to lower relationship satisfaction through increased intradyadic stress from relationship problems and also through more depressive symptomatology in men. The female extradyadic stress and intradyadic stress had partner effects on the male intradyadic stress and the male relationship satisfaction, respectively. Limitations as well as research and clinical implications for marriage and family therapists are discussed. © 2014 American Association for Marriage and Family Therapy.

    Stress is related to symptom severity among youth at clinical high-risk (CHR) for psychosis, although this relation may be influenced by protective factors. We explored whether the association of CHR diagnosis with social stress is moderated by the quality of parent-child relationships in a sample of 96 (36 CHR; 60 help-seeking controls) adolescents and young adults receiving mental health services. We examined self-reported social stress and parent-child relationships as measured by the Behavior Assessment System for Children, Second Edition (BASC-2), and determined CHR status from the clinician-administered Structured Interview for Psychosis-Risk Syndrome (SIPS). The social stress subscale, part of the clinical domain of the BASC-2, assesses feelings of stress and tension in personal relationships and the relations with parents subscale, part of the adaptive domain of the BASC-2, assesses perceptions of importance in family and quality of parent-child relationship. There was a modest direct relation between risk diagnosis and social stress. Among those at CHR, however, there was a significant relation between parent-child relationships and social stress (b=-0.73, t[92]=-3.77, psocial stress for those at risk for psychosis. Findings provide additional evidence to suggest that interventions that simultaneously target both social stress and parent-child relationships might be relevant for adolescents and young adults at clinical high-risk for psychosis.

    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.

    1977-01-01

    Local variations of Rayleigh (surface) circumferential ultrasonic wave velocity near a pipe-girth weld in large-diameter thin-wall type 316H stainless steel pipe were measured. The weldment was similar to those anticipated for the Liquid Metal Fast Breeder Reactor (LMFBR) piping systems. The residual stress distribution was estimated independently from shell theory for an elastic, infinite, thin shell with circumferential line loading. An upper bound on the magnitude of the residual stresses was estimated assuming the deformation of the shell was entirely elastic. The pattern of surface wave velocity variations matches the theoretical residual stress pattern closely. It is suggested that the monitoring of surface wave velocity variations might be used for characterizing residual stress patterns near critical welds in piping, aiding in design calculations, and for in-service monitoring of the state of stress of weldments

    The purpose of this study was to examine the extent to which stress moderated the relationships between problem-gambling severity and psychopathologies. We analyzed Wave-1 data from 41,869 participants of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC). Logistic regression showed that as compared to a non-gambling (NG) group, individuals at-risk gambling (ARG) and problem gambling (PPG) demonstrated higher odds of multiple Axis-I and Axis-II disorders in both high- and low-stress groups. Interactions odds ratios were statistically significant for stress moderating the relationships between at-risk gambling (versus non-gambling) and Any Axis-I and Any Axis-II disorder, with substance-use and Cluster-A and Cluster-B disorders contributing significantly. Some similar patterns were observed for pathological gambling (versus non-gambling), with stress moderating relationships with Cluster-B disorders. In all cases, a stronger relationship was observed between problem-gambling severity and psychopathology in the low-stress versus high-stress groups. The findings suggest that perceived stress accounts for some of the variance in the relationship between problem-gambling severity and specific forms of psychopathology, particularly with respect to lower intensity, subsyndromal levels of gambling. Findings suggest that stress may be particularly important to consider in the relationships between problem-gambling severity and substance use and Cluster-B disorders. Published by Elsevier B.V.

    Stress is an important factor affecting the health of working population. While work exposures are determinants of levels of work and life stress, we do not know whether similar or different exposures are related to stress levels for men and women. This study aimed to formally examine male/female differences in the relationships between psychosocial work exposures and work and life stress in a representative sample of Canadian labour market participants. We used data from 2012 cycle of the Canadian Community Health Survey (CCHS), a representative population-based survey conducted by Statistics Canada. The sample was restricted to employed labour force participants working 15+ hours per week (N = 8328, 48% female). To examine the relationship between work exposures and work and life stress, we conducted path analyses. Psychosocial work exposures included social support, job insecurity, job control, and job strain. Differences between estimates for men and women were explored using multigroup analyses, constraining paths between male and female models to be equivalent and examining the impact on change in model fit. Male/female differences were observed in the relationships between supervisor support and work stress levels as well as between job control, job insecurity, job strain, and life stress levels. Higher levels of supervisor support at work were associated with lower work stress among women, but not among men. Low job control had a direct protective effect on life stress for men but not for women, while high job strain had a direct adverse effect on life stress among women but not among men. Higher job insecurity was more strongly associated with higher life stress among men compared with women. The relationship between work stress and life stress was similar among men and women. The findings of this study suggest that the relationships between psychosocial exposures and work and life stress differ for men and women. Our study also raised important questions

    The cardiovascular system may represent a significant pathway by which marriage and stress influence health, but research has focused on married individuals cross-sectionally. This study examined associations among chronic stress, negative spousal relationship quality, and systolic blood pressure over time among middle-aged and older husbands and wives. Participants were from the nationally representative longitudinal Health and Retirement Study. A total of 1,356 (N = 2,712) married and cohabitating couples completed psychosocial and biomeasure assessments in waves 2006 and 2010. Analyses examined whether Wave 1 (2006) relationship quality and stress were associated with changes in blood pressure over time. The effects of stress and negative relationship quality were dyadic and varied by gender. Husbands had increased blood pressure when wives reported greater stress, and this link was exacerbated by negative spousal relationship quality. Negative relationship quality predicted increased blood pressure when both members of the couple reported negative quality relations. Findings support the dyadic biopsychosocial model of marriage and health indicating: (a) stress and relationship quality directly effect the cardiovascular system, (b) relationship quality moderates the effect of stress, and (c) the dyad rather than only the individual should be considered when examining marriage and health. © The Author 2015.

    In different-sex couples, individual and partner stress can both have a negative impact on relationship functioning (actor and partner effects). Gay and bisexual men experience unique stress (sexual minority stress), but few studies have examined the effects of this stress on relationship functioning among young male couples. The current study examined (a) actor and partner effects of general and minority stress (internalized stigma, microaggressions, victimization, and outness) on relationship functioning (relationship quality and negative relationship interactions), (b) interactions between individual and partner stress as predictors of relationship functioning, and (c) dyadic coping and relationship length as moderators of actor and partner effects. Actor-partner interdependence models were tested using data from 153 young male couples. There was strong support for actor effects. Higher general stress and internalized stigma were associated with lower relationship quality, but only for those in longer relationships. Additionally, higher general stress, internalized stigma, and microaggressions, and lower outness, were associated with more negative relationship interactions. There was limited support for partner effects. Having a partner with higher internalized stigma was associated with more negative relationship interactions, but none of the other partner effects were significant. There was no support for individual and partner stress interacting to predict relationship functioning or for dyadic coping as a stress buffer. Findings highlight the influence of one's own experiences of general and minority stress on relationship functioning, but raise questions about how partner stress influences relationship functioning among young male couples.

    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.

    Full Text Available Background: Working conditions have considerably changed and exposure to psychosocial risk factors, particularly occupational stress, has recently had an increasing trend. Studies have shown that sickness absence was the worst outcome of occupational stress. The present study aimed to assess the relationship between dimensions of occupational stress and sickness absence in a gas company in Boushehr, Iran. Methods: This cross-sectional study was conducted on 400 employees of a gas company, Boushehr, Iran who were selected through random sampling. Osipow occupational stress questionnaire was used to determine the participants’ stress levels. Then, the data were analyzed using descriptive statistics and Kruskal-Wallis test. Results: The participants’ mean of sickness absence was 2.164.57± days per year. Besides, 1.5%, 32.5%, 36.3%, and 29.8% of the participants had low, low to moderate, moderate to severe, and severe occupational stress, respectively. Additionally, the mean of total stress was moderate to severe among the study participants. This was also the case concerning the stress dimensions. The results revealed a significant relationship between the number of sickness absences and dimensions of occupational stress, including workload, role insufficiency, role conflict, responsibility, physical environment, and total stress (P=0.0001. Conclusion: The majority of the employees had high levels of occupational stress. Besides, a significant association was observed between the dimensions of occupational stress and sickness absence. Accordingly, to decrease the number of sickness absence, we should take measures to reduce occupational stress.

    Studies assessing the impact of stress on health outcomes are lacking in developing countries such as Botswana, in Southern Africa. This study examines the relationships between individual life stressors (stressful life events and chronic life stressors), social relationships and quality of life (QoL), for low-income urban residents in Francistown, Botswana. Although there are many studies of social support and quality of life, no studies have so far explored the relationship among the three variables. Selected concepts from stress theory are used as a conceptual framework. Using a cross-sectional quantitative design (both descriptive and explanatory), this study examined the associations among life stress (stressful life events and chronic life stressors), social relationships, and four indicators of health and QoL among a sample of 388 low-income urban dwellers in Francistown, Botswana. Using multiple regression models, the results of this study show that the availability of social relationships was associated with better physical and psychological health and level of independence. Controlling for the physical domain of QoL, social relationships buffered the effects of chronic life stressors on QoL and level of independence. Social relationships buffer the effects of stressful life events on quality, not on psychological well-being. Social relationships had no moderating effect on physical health, level of independence and on quality of life.

    The present research paper aims to bring deeper understanding and insight to perceptions and experiences of occupational stress from relationships at work in the cultural context of Vietnam. The paper also examines differences in perceptions, experiences of occupational stress from this problem and makes a comparison with perspectives in other cultures. Grounded theory approach is used to study occupational stress by collecting data from in-depth interviews with 42 academic women employed at Vietnamese higher education institutions to understand the meaning, the nature and source of the occupational stress from relationships at work they experience and the impact of occupational stress on their lives. Cultural factors play an important role in occupational stress. Cultural factors such as power distance and hierarchy influence perception, experiences of occupational stress and the ways occupational stress is responded to. The Vietnamese context differs from other cultural contexts in the range of factors perceived as stressors for Vietnamese women. This paper is the first grounded theory study of occupational stress among women academics in Vietnam that determines that the natural of the relationship at work play an important role in how women understand and respond to occupational stress and supports the growing evidence that occupational stress is common, global but different in other cultures.

    Chronic psychological stressis a risk factor formultiple diseases of aging. Accelerated cellular aging as indexed by short telomere length has emerged as a potential common biological mechanism linking various forms of psychological stress and diseases of aging. Stress appraisals determine the degree and type of biological stress responses and altered stress appraisals may be a common psychological mechanism linking psychological stress and diseases of aging. However, no previous studies have examined the relationship between stress appraisals and telomere length. We exposed chronically stressed female caregivers and non-caregiving controls (N= 50; M age = 62.14±6.10) to a standardized acute laboratory stressor and measured their anticipatory and retrospective threat and challenge appraisals of the stressor. We hypothesized that threat and challenge appraisals would be associated with shorter and longer telomere length respectively, and that chronic care giving stress would influence telomere length through altered stress appraisals. Higher anticipatory threat appraisals were associated with shorter age-adjusted telomere length (β = −.32, p = .03), but challenge appraisals and retrospective threat appraisals showed no independent association with telomere length. Caregivers reported significantly higher anticipatory (β = −.36, p = .006)and retrospective (β = −.29, p = .03) threat appraisals than controls, but similar challenge appraisals. Although there was no significant main effect of caregiver status on telomere length, care giving had a significant indirect effect on telomere length through anticipatory threat appraisals. Exaggerated anticipatory threat appraisals may be a common and modifiable psychological mechanism of psychological stress effects on cellular aging. PMID:22293459

    Latina/o college students have been shown to engage in more high risk drinking behavior than students from other ethnic minority groups, and are more likely to experience certain negative alcohol related consequences as a result of drinking. Previous research links stress to drinking among college students and indicates drinking occurs within a gendered context. Although this suggests an effect of gender role socialization, studies exploring these relationships among Latina/os are lacking. To explore potential relationships of stress, gender role prescriptions of the heritage culture, and drinking among Latina/o college students. Specifically, to explore potential interactions between stress and multiple dimensions of machismo and marianismo as related to alcohol use. Latina/o undergraduates (N = 248) completed a questionnaire. Self-reported stress, quantity of alcohol consumption, and frequency of binge drinking were recorded for all participants. Gender role prescriptions were assessed via endorsement of two dimensions of machismo (men) or two dimensions of marianismo (women). Stress was positively related to general quantity for women. Each dimension of machismo was distinctly related to binge drinking for men. Significant interactions emerged between both machismo and marianismo and stress as related to both alcohol use outcomes. For women, the moderating pattern between marianismo and stress varied according to type of alcohol use. Conclusions/Importance: Gender role beliefs influence the relationship between stress and alcohol use among Latina/o college students. Future research should account for the intersection of gender and culture when considering the stress-alcohol relationship.

This study aimed to investigate the relationship between personality traits, job satisfaction, and stress-related. Materials and Methods: This analytical study was performed among the telecommunications industry workers. 254 persons were randomly selected as the population of the study . Eysenck Personality Questionnaire and job satisfaction and stress questionnaires were applied to gather the required data. The collected data were analyzed using SPSS statistical software. Results: There was an inverse relationship between job satisfaction and job stress. The results of job stress questionnaires showed that 176, 37, and 8 employees were under high, moderate, and low stress, respectively. Overall job satisfaction scores were 14.25 + 10.95. The relationship between job stress and scale E showed a significant positive correlation between two variables so that as the level of introspection increases, people will feel more jop stress. The two scale N and L have meaningful relationship with job satisfaction so that the more stable the character, the higher the job satisfaction . Conclusion: It can be concluded that in order for promoting the job satisfaction and reducing the job stress, self-confidence enhancing skills should be trained to the employees.

    Based on the theoretical framework of Problem Behavior and Stress Reduction theories for problematic Internet use (PIU), this study aimed to investigate the relationship between parental PIU and the PIU among adolescents taking into consideration the stress levels of young people. This was a population-based parent and adolescent dyad health survey utilizing a random sampling technique. PIU for both parents and adolescents was measured by the Internet addiction test designed by Young. The stress level of adolescents was assessed using the stress subscale of the Depression Anxiety Stress Scale (DASS). Data were analyzed using logistic regression modeling techniques with adjustment for potential confounding factors with analysis on the modification effect of stress levels on the relationship between parent and adolescent PIU. Of the total 1,098 parent and adolescent dyads with usable information, 263 adolescents (24.0%) and 62 parents (5.7%) could be classified as moderate and severe problematic users of the Internet. About 14% (n = 157) of adolescents could be classified with moderate-to-severe stress. Regression analysis results suggested a significant interaction between parental PIU and adolescents' stress levels on adolescent PIU. Stratified regression analyses by stress level resulted in a significant parent and adolescent PIU relationship in the low stress group (odds ratio, 3.18; 95% confidence interval 1.65-6.14). However, the association between parent and adolescent PIU in the high stress group became insignificant. There was a significant parent and adolescent PIU relationship; however, this relationship is differentially affected by the stress status of the adolescent. The direct implication of the results is that parental Internet use should also be assessed and included as part of the treatment regime for adolescents.

    This study examined the prevalence of childbirth-related post-traumatic stress (PTS) symptoms at 2 years postpartum and the relationship between such symptoms and both self-reported parenting stress and perceptions of the mother-child relationship. 81 women completed measures of childbirth-related PTS symptoms at 6 weeks and 3 months postpartum; these results were used in an exploration of their predictive links with mother-child relationship and parenting measures at 2 years. 17.3% of respondents reported some PTS symptoms at a clinically significant level at 2 years postpartum. However, these symptoms were only weakly linked to parenting stress and were not related to mothers' perceptions of their children. However earlier PTS symptoms within 3 months of childbirth did show limited associations with parenting stress at 2 years but no association with child relationship outcomes once current depression was taken into account. Implications for clinical practice and the concept of childbirth-related post-traumatic stress disorder are discussed.

    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.

    The objective of the present study was to investigate the relationship between masticatory function-related factors (masticatory performance, occlusal contact area, maximum bite force, number of chewing strokes, and muscle activity) and the stress-relieving effects of chewing. A total of 28 healthy male subjects were instructed to rest or chew for 10min after 30min of stress loading with arithmetic calculations. Their stress state was assessed by measuring salivary cortisol levels. Saliva was collected at three time points: before stress loading, immediately after stress loading, and 10min after stress loading. Compared to resting, chewing produced a significantly greater reduction in the rate of change in salivary cortisol levels 10min after stress loading. A negative correlation was observed between the rate of decrease in salivary cortisol levels and the number of chewing strokes. No significant correlation was observed between the rate of decrease in salivary cortisol levels and other measurement items. In healthy dentulous people, the number of chewing strokes has been shown to be a masticatory function-related factor that affects stress relief from chewing, suggesting the possibility that more appropriate chewing would produce a greater effect psychological stress relief.

    To analyze the relationship between occupational stress and diseases in secondary school teachers in a city of Sichuan Province, and to provide a basis for the evaluation of the long-term effects of occupational stress in teachers. With secondary school teachers as the target population, the stratified cluster sampling was adopted to conduct three studies among 780, 119, and 689 secondary school teachers in a city of Sichuan Province in 1999, 2005, and 2009, respectively. The Occupational Stress Inventory-Revised Edition (OSI-R) and working ability index (WAI) were used to investigate occupational stress and diseases in secondary school teachers. The variation of occupational stress in secondary school teachers was compared between different periods and the relationship between the intensity of stress and diseases was evaluated, on the basis of which the variation of the relationship over time was analyzed. There were significant differences in occupational stress in secondary school teachers between different periods (Pstress and psychological stress were significantly higher in 2009 than in 1999 (Poccupational stress in 2009 changed with cardiovascular, respiratory, and mental diseases. The incidence of abnormal psychological stress was a risk factor for all chronic, respiratory, and mental diseases (OR: 1.88, 2.25, and 5.91). The time dependence of odds ratio was only found in the risk of respiratory diseases: occupational stress resulted in a significant increase in the risk of respiratory diseases over time (Pstress was a risk factor for mental diseases (OR=2.31). The intensity of occupational stress in secondary school teachers changes over time. Occupational stress elevates the risks of certain diseases and has a time-dependent effect on the risk of respiratory diseases. Occupational stress in secondary school teachers needs more attention and effective prevention.

    This study examined the relationships between chronic stress, food cravings, and body mass index. A community-based sample of adults (N = 619) completed a comprehensive assessment battery and heights and weights were measured. Chronic stress had a significant direct effect on food cravings, and food cravings had a significant direct effect on body mass index. The total effect of chronic stress on body mass index was significant. Food cravings partially mediated the relationship between chronic stress and body mass index. These findings are consistent with research that chronic stress may potentiate motivation for rewarding substances and behaviors and indicate that high food cravings may contribute to stress-related weight gain. © The Author(s) 2015.

  17. Emotional intelligence as a moderator in the stress-burnout relationship: a questionnaire study on nurses.

    2012-08-01

    To investigate inter-relationships between emotional intelligence (EI), work stress and burnout in a group of nurses in the Western Cape Province, South Africa. The moderating effect of EI in the stress-burnout relationship and group differences (nurses working in different wards) in burnout were also investigated. Stress and subsequent burnout commonly threaten the occupational health and well-being of nurses in South Africa and elsewhere. Developing EI in nurses may increase individual stress resistance and combat burnout. A cross-sectional research design with anonymous questionnaires was conducted. Self-report data were used. Survey data were collected from 122 nurses working in different wards at four hospitals from a private hospital group. The Swinburne University Emotional Intelligence Test, Sources of Work Stress Inventory and Maslach Burnout Inventory were used to measure EI, stress and burnout, respectively. Consistent inverse relationships between emotional control and management as dimensions of EI, and stress and burnout emerged. A differential effect of high vs. low EI on the stress-burnout relationship was evident. Workload and the work/family interface emerged as significant predictors of burnout. Respondents working in maternity, paediatric and ER wards reported more feelings of personal accomplishment than those working in general wards. Higher EI is significantly related with lower stress and burnout in a sample of South African nurses. The moderator effect of EI in the stress-burnout relationship suggests that enhanced EI may help diminish burnout development when chronic stress is experienced. EI developmental interventions, if introduced in nursing curricula, may increase emotional coping resources and enhanced social skills, which may benefit the long-term occupational health of nurses. This may be relevant in developing countries, where environmental stressors related to the organisational context (budget constraints) and wider social

    Academic incivility can increase student stress, jeopardize learning, damage relationships, and negatively impact the academic environment. This 3-year longitudinal study measured a cohort of prelicensure nursing students' progressive perceptions of stress, coping, student-student and faculty-student relationships, and levels of academic civility. While civility scores remained mild to moderately high overall, there was a slightly declining trend over the 3-year period. Perceived stressors and coping strategies and ways to improve academic civility are identified and discussed.

    Affiliative social relationships are impacted by stressors and can shape responses to stress. However, the effects of stress on social relationships in different contexts are not well understood. Meadow voles provide an opportunity to study these effects on peer relationships outside of a reproductive context. In winter months, female meadow voles cohabit with peers of both sexes, and social huddling is facilitated by exposure to short, winter-like day lengths in the lab. We investigated the role of stress and corticosterone (cort) levels in social behavior in short day-housed female meadow voles. A brief forced swim elevated cort levels, and we assessed the effects of this stressor on new and established relationships between females. In pairs formed following exposure to swim stress, the stressor significantly reduced the fraction of huddling time subjects spent with a familiar partner. Swim stress did not affect partner preferences in pairs established prior to the stressor. Finally, we examined fecal glucocorticoid metabolite levels via immunoassay in voles housed under short day (10h light) versus long day (14 h light) conditions and detected higher glucocorticoid levels in long day-housed voles. These findings support a role for stress regulation in the formation of social relationships in female meadow voles, and are consistent with a potential role for seasonal variation in cort in the behavioral transition from solitary to social. Together they highlight the importance of stress and possibly glucocorticoid signaling for social behavior. Copyright © 2016 Elsevier Inc. All rights reserved.

    The relationship between structural relaxation on molecular length scales and macroscopic stress relaxation was explored in a disordered block-copolymer melt. Experiments show that the structural relaxation time, measured by x-ray photon correlation spectroscopy is larger than the terminal stress relaxation time, measured by rheology, by factors as large as 100. We demonstrate that the structural relaxation data are dominated by the diffusion of intact micelles while the stress relaxation data are dominated by contributions due to disordered concentration fluctuations

    Suicide among United States service members is a significant public health concern. Intimate partner relationship stress may contribute to suicide risk, as a failed or failing relationship is the most commonly documented stressor preceding military suicide attempts and deaths. However, little is known about the manner by which relationship stressors are associated with the experience of military suicidality. A sample of 190 psychiatrically hospitalized military personnel and adult dependents enrolled in an ongoing randomized controlled trial evaluating the efficacy of an inpatient cognitive behavioral treatment for suicidality were included in this study. Analyses examined depression, hopelessness, and suicidality among participants with (n = 105) and without (n = 85) self-reported romantic relationship stress. Over half (55%) of the sample reported current romantic relationship stress. Compared to participants without current romantic relationship stress, results indicated that individuals reporting current romantic relationship stress were more hopeless (AOR = 1.07 (95% CI: 1.01-1.12), p = 0.020), more likely to endorse multiple suicide attempts (AOR = 1.96 (95% CI: 1.01-3.79), p = 0.046), had higher overall suicide risk (AOR = 2.49, (95% CI: 1.03-6.06), p = 0.044), and were more likely to report that the reason for their suicidality was at least in part to get a reaction from others. Findings suggest romantic relationship stress is associated with greater suicide risk, and have clinical implications for suicide prevention and intervention. Future research may examine mechanisms and pathways between romantic relationship stress, suicidality, and prevention and intervention strategies. Published by Elsevier Inc.

    Past research has demonstrated negative associations between exposure to stressors and quality of interpersonal relationships among children and adolescents. Nevertheless, underlying mechanisms of this association remain unclear. Chronic stress has been shown to disrupt prefrontal functioning in the brain, including inhibitory control abilities, and evidence is accumulating that inhibitory control may play an important role in secure interpersonal relationship quality, including peer problems and social competence. In this prospective longitudinal study, we examine whether changes in inhibitory control, measured at both behavioral and neural levels, mediate the association between stress and changes in secure relationship quality with parents and peers. The sample included 167 adolescents (53% males) who were first recruited at age 13 or 14 years and assessed annually three times. Adolescents' inhibitory control was measured by their behavioral performance and brain activities, and adolescents self-reported perceived stress levels and relationship quality with mothers, fathers, and peers. Results suggest that behavioral inhibitory control mediates the association between perceived stress and adolescent's secure relationship quality with their mothers and fathers, but not their peers. In contrast, given that stress was not significantly correlated with neural inhibitory control, we did not further test the mediation path. Our results highlight the role of inhibitory control as a process through which stressful life experiences are related to impaired secure relationship quality between adolescents and their mothers and fathers.

We adopted a descriptive and correlational research design and collected data from 261 pregnant women during their first trimester in southern Taiwan using structured questionnaires. Results showed that (1 stress was significantly and positively correlated with Yang-Xu, Yin-Xu, and Tan-Shi-Yu-Zhi constitutions, respectively; (2 Yin-Xu and Tan-Shi-Yu-Zhi constitutions had significant correlations with all symptoms of discomfort, while Yang-Xu had significant correlations with all symptoms of discomfort except for “running nose”; (3 Tan-Shi-Yu-Zhi constitution and stress were two indicators for “fatigue”; Tan-Shi-Yu-Zhi was the indicator for “nausea”; Yang-Xu and Yin-Xu were indicators for “frequent urination.” Our findings also indicate that stress level affects constitutional changes and that stress and constitutional change affect the incidence of discomfort. This research can help healthcare professionals observe these discomforts and provide individualized care for pregnant women, to nurture pregnant women into neutral-type constitution, minimize their levels of discomfort, and promote the health of the fetus and the mother.

    Both exposure to stress and perseverative cognitions (PCs)-repetitive cognitive representations of real or imagined stressors-are linked with poor psychological health. Yet, stress exposure and PCs are correlated, thus potentially obscuring any unique effects. The purpose of this paper is to concurrently test associations between stress exposure and PCs and psychological health to examine the independent relationship of each with psychological health. Moreover, we examined whether these relationships are similar across sex, age, and race. An adult community sample (n = 302) completed a measure of stress exposure, three PCs scales, and questionnaires assessing self-reported psychological health, including emotional well-being, vitality, social functioning, role limitations due to personal problems, subjective well-being, depressive symptoms, and poor sleep quality. Structural equation modeling was used to test a model in which both stress exposure and PCs predict psychological health. PCs consistently predicted all the psychological health outcomes, but stress was largely unrelated to the outcomes despite bivariate correlations suggesting a relationship. A follow-up model identified indirect effects of stress exposure on psychological health via PCs. Results were fairly consistent regardless of one's sex, age, or race. PCs robustly predicted all of the psychological health outcomes, intimating PCs as a common pathway to poor psychological health. Results have implications for stress interventions, including the need to address PCs after experiencing stress.

    Community mental health providers often operate within stressful work environments and are at high risk of emotional exhaustion, which can negatively affect job performance and client satisfaction with services. This cross-sectional study examined the relationships between organizational stress, provider adaptability, and organizational commitment. Variables were analyzed with moderated multilevel regression in a sample of 311 mental health providers from 49 community mental health programs. Stressful organizational climate, characterized by high levels of emotional exhaustion, role conflict, and role overload, was negatively related to organizational commitment. Organizational stress moderated the relationship between provider adaptability and organizational commitment, such that those who were more adaptable had greater levels of organizational commitment when organizational stress was low but were less committed than those who were less adaptable when organizational stress was high. Providers higher in adaptability may perceive their organization as a greater fit when the work environment is less stressful; however, highly adaptable providers may also exercise choice that manifests in lower commitment to staying in an overly stressful work environment. Service systems and organizational contexts are becoming increasingly demanding and stressful for direct mental health service providers. Therefore, community mental health organizations should assess and understand their organizational climate and intervene with empirically based organizational strategies when necessary to reduce stressful climates and maintain adaptable employees.

    Full Text Available As one of the serious complications of diabetes, diabetic retinopathy(DRhas become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species(ROSproduction due to damage of electron transport chain proteins, mitochondrial DNA(mtDNAdamage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. In this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

    Full Text Available Stroke variably activates interleukin- (IL- 17 expression, reduces regulatory T cells, and induces oxidative stress, which may support neurodegeneration. Ischemic stroke patients were screened for depressive symptoms (Center for Epidemiological Studies Depression (CES-D and cognitive status (Mini Mental State Examination. Proinflammatory cytokines (IL-17, IL-23, and interferon- [IFN-] γ, anti-inflammatory cytokine IL-10, and lipid hydroperoxide (LPH, a measure of oxidative stress, were assayed from fasting serum. Of 47 subjects (age 71.8 ± 14.4 years, 36% female, 19 had depressive symptoms (CES-D ≥ 16, which was associated with poorer cognitive status (F1,46=8.44, P=0.006. IL-17 concentrations did not differ between subjects with and without depressive symptoms (F1,46=8.44, P=0.572; however, IL-17 was associated with poorer cognitive status in subjects with depressive symptoms (F1,46=9.29, P=0.004. In those subjects with depressive symptoms, IL-17 was associated with higher LPH (ρ=0.518, P=0.023 and lower IL-10 (ρ=-0.484, P=0.036, but not in those without. In conclusion, poststroke depressive symptoms may be associated with cognitive vulnerability to IL-17 related pathways, involving an imbalance between proinflammatory and anti-inflammatory activity and increased oxidative stress.

    2012-01-01

    The current study examines the moderating effect of customer service orientation and emotional energy on the stress-performance relationship for 681 U.S. casual dining restaurant employees. Customer service orientation was hypothesized to moderate the stress-performance relationship for Front-of-House (FOH) workers. Emotional energy was hypothesized to moderate stress-performance for Back-of-House (BOH) workers. Contrary to expectations, customer service orientation failed to moderate the effects of stress on performance for FOH employees, but the results supported that customer service orientation is likely a mediator of the relationship. However, the hypothesis was supported for BOH workers; emotional energy was found to moderate stress performance for these employees. This finding suggests that during times of high stress, meaningful, warm, and empathetic relationships are likely to impact BOH workers' ability to maintain performance. These findings have real-world implications in organizational practice, including highlighting the importance of developing positive and meaningful social interactions among workers and facilitating appropriate person-job fits. Doing so is likely to help in alleviating worker stress and is also likely to encourage worker performance.

    Full Text Available Noise exposure is one of the major occupational hazards in many places, and has several health effects, including hearing loss and psychological effects such as sleep disturbances and mental stress. The objective of this research was to determine the relationship between noise and stress and other risk factors that affect job stress. A cross-sectional comparative design involved a total of 326 workers consisting of 220 workers in high noise conditions and 106 workers in low noise conditions. The data were collected directly from the respondents by filling out the questionnaire on worker characteristics, the stress diagnostic questionnaire, and the symptom checklist 90, through discussions with company management, and by measurement of noise levels. The job stress prevalence in workers in high noise conditions was 55% and in those in low noise conditions 24.5%. The results showed that risk factors such as gender of workers, noise conditions, habitual use of ear plugs, shift work, and work stressors had a significant relationship with job stress. Multivariate analysis indicated that the habit of using earplugs was a dominant risk factor causing job stress. The prevalence of job stress in high noise conditions was higher than that in workers in low noise conditions. Noise conditions have a significant relationship with job stress (OR=2.46; 95% CI 1.33 - 4.55. Workers in high noise conditions who did not always use or never had used ear plugs had a higher chance of experiencing stress than those in low noise conditions who did not need ear plugs (OR=21.76; 95% CI 8.09 - 58.52. This study supported that noise exerts its health effect via stress, since noise often raise stress in various ways.

  1. Moderators and Mediators of the Relationship Between Stress and Insomnia: Stressor Chronicity, Cognitive Intrusion, and Coping

    Study Objectives: To assess moderators, such as stressor chronicity, and mediators, including stress response in the form of cognitive intrusion and coping behavior, of the prospective association between naturalistic stress and incident insomnia. Design: Longitudinal. Setting: Epidemiological. Participants: A community-based sample of good sleepers (n = 2,892) with no lifetime history of insomnia. Interventions: None. Measurements and Results: Participants reported the number of stressful events they had encountered at baseline, as well as the perceived severity and chronicity of each event. Similarly, volitional stress responses such as coping, as well as more involuntary responses such as cognitive intrusion were assayed for each stressor. Follow-up assessment 1 y hence revealed an insomnia incidence rate of 9.1%. Stress exposure was a significant predictor of insomnia onset, such that the odds of developing insomnia increased by 19% for every additional stressor. Chronicity significantly moderated this relationship, such that the likelihood of developing insomnia as a result of stress exposure increased as a function of chronicity. Cognitive intrusion significantly mediated the association between stress exposure and insomnia. Finally, three specific coping behaviors also acted as mediators: behavioral disengagement, distraction, and substance use. Conclusions: Most studies characterize the relationship between stress exposure and insomnia as a simple dose-response phenomenon. However, our data suggest that certain stressor characteristics significantly moderate this association. Stress response in the form of cognitive intrusion and specific maladaptive coping behaviors mediate the effects of stress exposure. These findings highlight the need for a multidimensional approach to stress assessment in future research and clinical practice. Citation: Pillai V, Roth T, Mullins HM, Drake CL.

    Based on a large scale population study, associations between experienced non-reciprocity in social relationships and three health indicators (depressive symptoms, self-rated health, sleeping problems) are analysed. The norm of reciprocity is commonly defined as the obligation to return actions or services provided by another person. We use baseline survey data of the Heinz Nixdorf Recall Study. Participants (n = 4814) were randomly selected from mandatory lists of residency from three adjacent cities of the Ruhrregion (Germany) with a response rate of 55.8 %. Non-reciprocity is measured by a questionnaire containing three scales: "partnership", "parent-child", and "non-specific relationships". Depressive symptoms are assessed by the German short version of the CES-D scale, self-rated health by a single widely tested item and sleeping problems by an index consisting of three items. Associations are explored using logistic regression analyses with age, education, occupational position and two indicators of social support as control variables. Results show that men and women who experience non-reciprocity in social relationships have significantly elevated risks of depressive symptoms, poor self-rated health and sleeping problems. Associations decrease after controlling for age, education, occupational position and social support but remain significant in most cases. The reciprocity approach proposed here offers the opportunity to systematically explore negative aspects of social relationships and resulting health consequences.

    It was demonstrated experimentally that only one test specimen is required to determine the combined-load stress-strain relationships of a given fiber composite system. These relationships were determined using a thin angle-plied laminate tube and subjecting it to a number of combined-loading conditions. The measured data obtained are compared with theoretical predictions. Some important considerations associated with such a test are identified, and the significance of combined-load stress-strain relationships in certain practical designs are discussed.

    Hydraulic fracturing stress measurements and acoustic borehole televiewer logs were run in holes USW G-1 and USW G-2 at Yucca Mountain as part of the Nevada Nuclear Waste Storage Investigations for the U. S. Department of Energy. Eight tests in the saturated zone, at depths from 646 to 1288 m, yielded values of the least horizontal stress S/sub h/ that are considerably lower than the vertical principal stress S/sub v/. In tests for which the greatest horizontal principal stress S/sub H/ could be determined, it was found to be less than S/sub v/, indicating a normal faulting stress regime. The borehole televiewer logs showed the presence of long (in excess of 10 m), vertical, drilling-induced fractures in the first 300 m below the water table. These are believed to form by the propagation of small preexisting cracks under the excess downhole fluid pressures (up to 5.2 MPa) applied during drilling. The presence of these drilling-induced hydrofractures provides further confirmation of the low value of the least horizontal stresses. A least horizontal principal stress direction of N60 0 W--N65 0 W is indicated by the orientation of the drilling-induced hydrofractures (N25 0 E--N30 0 E), and the orientation of stress-induced well bore breakouts in the lower part of USW G-2 (N65 0 W). This direction is in good agreement with indicators of stress direction from elsewhere at the Nevada Test Site. The observed stress magnitudes and directions were examined for the possibility of slip on preexisting faults. Using these data, the Coulomb criterion for frictional sliding suggests that for coefficients of friction close to 0.6, movement on favorably oriented faults could be expected

    This selective review aims to highlight some of the most recent empirical or theoretical advancements in the study of social relationships as buffers against stress and as protective factors against risk for disease, focusing on articles published between 2013 and 2015. The review summarizes novel findings showing that social relationships can protect individuals against negative health outcomes associated with chronic adversity and can be associated with reduced cumulative physiological damage (allostatic load). There is also evidence that some relationships can be a source of stress. Additionally, recent findings concerning the psychological and neurobiological mechanisms of action for social support, the developmental patterning of social stress-buffering and recent experimental studies attempting to change relationships to affect health are also reviewed.

    Whereas significant advances have been made in understanding how exposure to early adversity "gets under the skin" of children to result in long term changes in developmental outcomes, the processes by which positive social relationships become biologically embedded remain poorly understood. The aim of this study was to understand the pathways by which maternal and infant social environments become biologically embedded in infant cortisol reactivity. Two hundred seventy-two pregnant women and their infants were prospectively assessed during pregnancy and at 6 months postpartum. In serial mediation analyses, higher perceived social support from partners during pregnancy was associated with lower infant cortisol reactivity or larger decreases in cortisol in response to a stressor at 6 months of age via lower self-reported prenatal maternal depression and higher mother-infant interaction quality. The findings add to our understanding of how perinatal social relationships become biologically embedded in child development. © 2017 Wiley Periodicals, Inc.

    Families experiencing child maltreatment or risk factors for child maltreatment often receive referrals to interventions focused on changing parenting practices. Compliance with specific parenting programs can be challenging as many of the stressors that place families at-risk may also interfere with program participation. Because families may receive limited benefit from programs they do not fully receive, it is critical to understand the relationship between parenting stress and barriers to program completion. We used structural equation modeling to examine the relationship among parenting stress, perceived barriers to program participation, and program completion in two datasets involving low-income parents. Data were collected at two time points from a sample of parents involved with child welfare services and a sample of parents considered at-risk of future involvement (total study n = 803). Direct paths from parenting stress at time 1 to barriers to participation and parenting stress at time 2, and from parenting stress at time 2 to program completion were significant. Interestingly, increased barriers to participation were related to increased parenting stress at time 2, and greater parenting stress was related to increased program completion. Results suggest that with increasing levels of parenting stress, parents have an increased likelihood of completing the program. Assessing and addressing the influence of perceived barriers and parenting stress on program participation may decrease the likelihood of treatment attrition.

    The association between stress and health has been well researched in the past; however, comparatively few mediators have been tested to understand the underlying mechanism. With increasing awareness on mental well-being, this study evaluated the relationship between perceived stress and perceived health and examined mental well-being as a mediator. Two-hundred undergraduates aged 21 to 26 years completed the English Perceived Stress Scale, Health Status Questionnaire and Asian Mental Well-Being Scale that assess perceived stress, perceived health and mental well-being, respectively. Factor analysis and structural equation modelling on the Perceived Stress Scale replicated the reported two-factor structure after excluding an insignificant item. Linear multiple regression analyses indicated that perceived stress was negatively associated with perceived health. Results showed that mental well-being partially mediated the relationship between perceived stress and perceived health, although it is acknowledged that this association could be bidirectional. Findings from the present study suggest that future research could focus on reducing stress and improving mental well-being to alleviate the effect of stress on health. © 2013 John Wiley & Sons, Ltd.

    The present study examined the relationships among grit, academic performance, perceived academic failure, and stress levels of Hong Kong associate degree students using path analysis. Three hundred and forty-five students from a community college in Hong Kong voluntarily participated in the study. They completed a questionnaire that measured their grit (operationalized as interest and perseverance) and stress levels. The students also provided their actual academic performance and evaluated their perception of their academic performance as a success or a failure. The results of the path analysis showed that interest and perseverance were negatively associated with stress, and only perceived academic failure was positively associated with stress. These findings suggest that psychological appraisal and resources are more important antecedents of stress than objective negative events. Therefore, fostering students' psychological resilience may alleviate the stress experienced by associate degree students or college students in general.

    Using Smith's (1986) cognitive-affective model of athletic burnout as a guiding framework, the purpose of this study was to examine the relationships among athletes' stress in life, negative thoughts, and the mediating role of negative thoughts on the stress-burnout relationship. A total of 300 college student-athletes (males = 174; females = 126, M age  = 20.43 y, SD = 1.68) completed the College Student Athlete's Life Stress Scale (CSALSS; Lu et al., 2012), the Automatic Thoughts Questionnaire (ATQ; Hollon & Kendall, 1980), and the Athlete Burnout Questionnaire (ABQ; Raedeke & Smith, 2001). Correlational analyses found that two types of life stress and four types of negative thoughts correlated with burnout. Additionally, hierarchical regression analyses found that four types of negative thoughts partially mediated the stress-burnout relationship. We concluded that an athlete's negative thoughts play a pivotal role in predicting athletes' stress-burnout relationship. Future study may examine how irrational cognition influences athletes' motivation and psychological well-being.

    Full Text Available The purpose of this study was to explore the mediating and moderating effects of parenting alliance on the relationship between marital adjustment, as represented by the dimensions dyadic consensus, dyadic satisfaction, dyadic cohesion, and affectional expression, and maternal and paternal stress. Self-report data were gathered from 236 Italian families (236 mothers: M = 40.9; SD = 4.4 and 236 fathers: M = 42.9; SD = 4.8 of children aged 6–11 years (M = 8.6; SD = 1.7. A set of regression analyses were conducted to examine whether parenting alliance mediates or moderates the relationship between marital adjustment and parenting stress. Regression analyses were consistent with a model of coparenting as a mediator but not as a moderator of the relationship between marital adjustment and parenting stress.

    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.

    Several studies have linked teachers' personality characteristics and sense of efficacy to stress. However, investigating the relationship between these three constructs in this context was limited. This study aims to investigate the relationship between personality, sense of efficacy and perceived stress among Korean teachers. A total of 137 teachers working in elementary, middle, and high schools located in Seoul, South Korea were recruited for the study. The participants were administered Temperament and Character Inventory, Teacher's Sense of Efficacy Scale (TSES), and Perceived Stress Scale. The TSES was negatively correlated with harm avoidance and positively correlated with persistence, self-directedness, cooperativeness, and self-transcendence. Perceived stress was positively correlated with harm avoidance and negatively correlated with persistence and self-directedness. The path analysis showed that harm avoidance directly predicted perceived stress (β=0.37, 95% CI=0.21-0.53, p=0.002), and self-directedness and persistence predicted one's sense of efficacy (β=0.18, 95% CI=0.01-0.39 and β=0.31, 95% CI=0.10-0.47), which predicted perceived stress (β=-0.21, 95% CI=-0.39 to -0.02). The results of the present study indicate that harm avoidance might be associated with stress-proneness, while persistence, self-directedness, and sense of efficacy might act as protective resources against stress in Korean teachers.

    In geomagnetic field, a series of tensile experiments on the low-carbon steel sticks were carried out. A special homemade detector was used to measure the magnetic gradient on the material surface. The results showed that the relationship between the magnetic gradient and the stress varied with different conditions of measurement. There was no obvious correlation between the magnetic gradient and the tensile stress if the sample remained on the material test machine. If the sample was taken off from the machine, the measured magnetic gradient was linear with the prior maximum stress. In Nanjing, PR China, a place of 32 o N latitude, the slope of the linear relationship was about 67 (uT/m)/MPa. This offered a new method of non-destructive stress testing by measuring the magnetic gradient on the ferromagnetic component surface. The prior maximum applied stress of the sample could be tested by measuring the present surface magnetic gradient. Actually this phenomenon was the metal magnetic memory (MMM). The magnetic gradient near the stress concentration zone of the sample, the necking point, was much larger than other area. Thus, the hidden damage in the ferromagnetic component could be detected early by measuring the magnetic gradient distribution on its surface. In addition, the magnetic memory signal gradually weakened as the sample was taken off and laid aside. Therefore, it was effective for a given period of time to detect the stress or stress concentration based on the MMM testing.

    This study extends recent coach stress research by evaluating how coaches perceive their stress experiences to affect athletes, and the broader coach-athlete relationship. A total of 12 coaches working across a range of team sports at the elite level took part in semi-structured interviews to investigate the 3 study aims: how they perceive athletes to detect signals of coach stress; how they perceive their stress experiences to affect athletes; and, how effective they perceive themselves to be when experiencing stress. Following content analysis, data suggested that coaches perceived athletes able to detect when they were experiencing stress typically via communication, behavioural, and stylistic cues. Although coaches perceived their stress to have some positive effects on athletes, the overwhelming effects were negative and affected "performance and development", "psychological and emotional", and "behavioural and interaction" factors. Coaches also perceived themselves to be less effective when stressed, and this was reflected in their perceptions of competence, self-awareness, and coaching quality. An impactful finding is that coaches are aware of how a range of stress responses are expressed by themselves, and to how they affect athletes, and their coaching quality. Altogether, findings support the emerging view that coach stress affects their own, and athlete performance.

    Acid rain is a worldwide environmental problem. Serious acid rain pollution in subtropical China has constituted a potential threat to the health of the local forest. In the present paper, the changing properties of the chlorophyll concentration and spectral reflectance at the visible wavelengths for the six subtropical broad-leaved tree species leaves under simulated acid rain (SAR) treatment with different pH levels were studied. With the increasing strength of the SAR, the chlorophyll concentrations of the experimental species under pH 2.5 and pH 4.0 treatment were higher than that under pH 5.6; the spectral reflectance at the visible wavelengths for pH 2.5 and pH 4.0 were lower than that for pH 5.6 in general; while there weren't significant differences between pH 2.5 and pH 4.0. After the treatment with different levels of SAR, the differences in spectral reflectance at the visible wavelengths mainly focused around the green peak and red edge on the reflectance curve. The subtropical broad-leaved tree species studied were relatively not sensitive to acid rain stresses; some stronger acid rain may accelerate the growth of the tree species used here to some extent.

    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.

These findings are relevant as around 20% of young people are affected by moderate-to-severe acne, and indeed acne severity is associated with increased risks of anxiety, depression and suicidal ideation.2 The authors identified that “stress severity strongly correlated with an increase in acne severity,” and suggested that stress likely has an important role in the pathogenesis of acne.1 However, the paper could have been taken further to better establish the true extent of this relationship, and ultimately whether certain patients will benefit from clinical interventions based on their perceived stress scale. View the original paper by Zari and Alrahmani.

    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.

    Full Text Available Introduction Soil salinity is one of the major abiotic stresses affecting plant growth and production. It is estimated that approximately half of the irrigated lands of Iran are affected by salinity and much of the agricultural lands of Iran especially in the central regions are susceptible to salinity. According to the development of saline soils and water resources, utilization of halophytes as alternatives for cultivation in saline conditions could be a suitable strategy to crop production. In addition to understanding the physiological salinity tolerance pathways, studying such crops could help to plant breeding and transferring these useful traits to crop species and also domestication of these plants. Materials and methods This experiment was conducted in 2009-2010 in Salinity Research Station of faculty of agriculture, Ferdowsi University of Mashhad as split-plot based on Complete Randomized Block Design with three replications. Salinity as the main plot had two levels of 5.2 and 16.5 dSm-1 and five kochia ecotypes including Birjand, Urmia, Borujerd, Esfahan and Sabzevar were allocated as sub-plot. Seedlings were irrigated with saline water having electrical conductivity (EC of 5.2 dSm-1 until the full establishment and thereafter salinity stress was imposed with saline water having EC=16.5 dSm-1. Physiological and biochemical traits were measured in the youngest fully expanded leaf at the beginning of the anthesis and shoot biomass at the end of the growth season. Data analysis was performed using Minitab 16 and means were compared by LSD test at a significance level of 0.05. Results and Discussion Results indicated that biomass was increased in Birjand, Isfahan and Urmia ecotypes as salinity level increased while it was decreased in Sabzevar and Boroujerd ecotypes. A reduction of 34, 31, 11 and 29 percentage and an increase of 4 percentage in seed yield was seen in Sabzevar, Birjand, Boroujerd, Urmia and Isfahan, respectively. Harvest

    Understanding how veterans appraise their post-deployment experiences could provide insight into better assisting their deployment transitions. We aimed to assess the factor structure of positive and negative post-deployment appraisals in Australian veterans and to examine the resultant factors in their relationship with military stress and psychological health. Questions capturing post-deployment attitudes were developed by the researchers in collaboration with veterans. The questions were administered to 1938 veterans and the results factor analysed. The relationships between post-deployment appraisal, military stress and psychological health were examined using Structural Equation Modelling. A three-factor solution was found for the post-deployment appraisal questions; representing personal development, lack of recognition, and appreciation of life and country. Military stress was associated with the three factors and psychological health. The three factors were weakly to moderately associated with psychological health. Mediation between military stress and psychological health by any post-deployment appraisal factor was minimal. Post-deployment appraisal measures three important attitudes and concerns of veterans after deployment. Military stress is associated with the post-deployment appraisal factors. However, the factors did not mediate the relationship between military stress and psychological health. These factors provide insight into how veterans appraise their complex array of post-deployment experiences, and may provide useful in regard to transitions and integration into civilian life.

    Full Text Available The aim of this study was to examine the relationship between cognitive competitive anxiety intensity and coping strategies in table tennis players. One hundred and two (102 US competitive table tennis players of age range from 10 to 60 filled out a Revised Competitive State Anxiety Inventory-2 (CSAI-2R, Cox et al., 2003 at least 30 minutes before the start of their tournament match and a Modified Cope questionnaire (MCOPE; Crocker and Graham, 1995 15 minutes after they finished their match. Our study found significant differences between low and high cognitive competitive anxiety groups with regard to the use of coping strategies. The high cognitive competitive anxiety intensity group used significantly more behavioral disengagement (avoidance coping, p ≤ 0.05, denial coping strategies (emotion focused coping, p ≤ 0.01 compared to the low cognitive anxiety intensity group. Our results suggest that there is some connection between anxiety intensity and coping strategies. If the cognitive anxiety intensity (for example, intensity from worrying is very high, an athlete might be more likely to use avoidance coping (such as behavioral disengagement and emotion-focused coping (such as denial and venting of emotions compared to athletes who have low cognitive competitive anxiety. Furthermore, gender differences in cognitive anxiety and direction were found. Confidence management techniques such as positive self-talk, breathing techniques and visualization should be taught to athletes to assist them in coping with their competitive anxiety better and to enhance their performance.

    Women subject to violence by their intimate partners often experience a range of psychosocial problems such as depression, excessive alcohol use, and stressful life events that, in turn, lead to health issues. This study examined psychosocial difficulties and oxidative stress levels in abused and non-abused Korean women and analyzed the relationship between psychosocial outcomes and oxidative stress levels. Markers were determined in 16 women (seven abused, nine non-abused). The two groups of women (abused and non-abused) were compared with respect to scores in depression, alcohol use, life stress events, and oxidative stress biomarkers using the Mann-Whitney U test. Correlations between depression, alcohol use, life stress events, and oxidative stress biomarkers were tested by the Spearman rank correlation coefficient. The abused women had significantly higher levels of oxidative stress markers and significantly lower levels of antioxidants than the non-abused women. Life stress events and oxidative biomarker levels were significantly correlated. These findings have implications for both social services providers and medical personnel when assessing abused women to ensure that they receive the most appropriate service. © 2016 National Association of Social Workers.

    Research has suggested that psychological stress is associated with reduced lung function and with the development of respiratory disease. Among the major potential sources of stress in adulthood are working conditions. We aimed to examine the relationship of work stress with lung function. We drew on 4-year prospective data from the Survey of Health, Ageing and Retirement in Europe. The analyzed sample comprised 2627 workers aged 50 years or older who were anamnestically free of respiratory disease. Work stress at baseline was operationalized by abbreviated instruments measuring the well-established effort-reward imbalance model (seven items) and the control component of the job-demand control (two items). Peak expiratory flow (PEF) was determined at baseline and at follow-up. Continuous and categorized (i.e., by the tertile) work stress variables were employed in multivariable linear regression models to predict PEF change. Work stress did not show statistically significant associations with PEF change. For instance, the unstandardized regression coefficient for PEF decline according to high versus low effort-reward imbalance was -1.41 (95% confidence interval = -3.75, 0.94). Our study is the first to examine prospective relationships between work stress and PEF. Overall, we did not observe meaningful associations. Future studies should consider a broader spectrum of spirometric parameters and should expand research to younger and possibly less-selected working populations (i.e., aged <50 years).

    To clarify the prevalence of stress, and examine the relationship between sleep disorders and stress coping strategies among highly stressed individuals in the general Japanese population. A cross-sectional nationwide survey was undertaken in November 2007. Men and women were randomly selected from 300 districts throughout Japan. Data from 7671 (3532 men (average age 53.5 ± 17.0 years) and 4139 women (average age 53.9 ± 17.7 years)) were analyzed. Participants completed a self-reported questionnaire on stress, sleep disorders, and stress coping strategies in the previous month. Highly stressed individuals comprised 16.6% (95% confidence interval 15.8-17.5%) of the total sample, and most were aged 20-49 years. In multiple logistic regression, symptoms of insomnia (ie, difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening), excessive daytime sleepiness, nightmares, daytime malfunction, and lack of rest due to sleep deprivation were more prone to occur in highly stressed individuals. In addition, logistic regression analysis controlling for other adjustment factors revealed that stress coping strategies such as 'giving up on problem-solving', 'enduring problems patiently', 'smoking' and 'drinking alcohol' were positively associated with the above-mentioned sleep disorders. On the other hand, stress coping strategies such as 'exercising', 'enjoying hobbies', and 'sharing worries' were inversely associated with the above-mentioned sleep disorders. Distraction-based stress coping (eg, hobbies, exercise, and optimistic thinking) was found to be preferable to problem-based stress coping in a highly stressed Japanese general population.

The statistical analysis was performed using student’s t-test, One Way ANOVA, correlation coefficient, and linear regression model through SPSS statistical software (version 11.5.   Results: The results showed that the mean score of occupational stress and work ability was 149 ± 0.01 and 38.81±0.05, respectively. There was a negative correlation between job-related stress and work ability. Midwives with higher occupational stress experienced poorer work ability (P=0.021, r=-0.061.   Conclusion: Sever work stress is associated with reduced work ability. So it is recommended to eliminate or decrease occupational stress and increase work ability among Iranian midwives using preventive measures, although identification of sources of occupational stress seems necessary in order to adopt appropriate stress management strategies.

    Common mental disorders (CMD) are a constellation of mental health conditions that include depression, anxiety, and other related nonpsychotic affective disorders. Qualitative explanatory models of mental health among reproductive-aged women in India reveal that distress is strongly associated with CMD. The relationship of perceived stress and CMD might be attenuated or exacerbated based on an individual's sociodemographic characteristics. To screen for Common Mental Disorders (CMD) among reproductive-aged women from rural western India and explore how the relationship between perceived stress and CMD screening status varies by sociodemographic characteristics. Cross-sectional survey of 700 women from rural Gujarat, India. CMD screening status was assessed using Self-Reported Questionnaire 20 (SRQ-20). Factors associated with CMD screening status were evaluated using multivariable logistic regression. Effect modification for the relationship of perceived stress and CMD screening status was assessed using interaction terms and interpreted in terms of predicted probabilities. The analytic cohort included 663 women, with roughly 1 in 4 screening positive for CMD (157, 23.7%). Poor income, low education, food insecurity, and recurrent thoughts after traumatic events were associated with increased risk of positive CMD screen. Perceived stress was closely associated with CMD screening status. Higher education attenuated the relationship between high levels of stress and CMD screening status (82.3%, 88.8%, 32.9%; P value for trend: 0.03). Increasing income and age attenuated the link between moderate stress and CMD. Our findings suggest a high burden of possible CMD among reproductive-aged women from rural western India. Higher education might mitigate the association between elevated stress and CMD. Future efforts to improve mental health in rural India should focus on preventing CMD by enhancing rural women's self-efficacy and problem-solving capabilities to overcome

    The goal of this study was to analyze the relationships between self-esteem, perceived stress, the quality of different types of interpersonal relationships, and gender in adolescents. This study used a sample of 1614 adolescent high school students and robust data analytic techniques to test the proposed relationships. The results partially supported the initial hypothesis in that perceived stress mediated the relationships between self-esteem and four of the types of interpersonal relationships (i.e., same-sex peer relationships, opposite-sex peer relationships, parent-child relationships, and teacher-student relationships) and moderated the relationship between self-esteem and same-sex peer relationships. In addition, a moderated role of gender was also partially supported in that perceived stress mediated the relationships between self-esteem and same-sex peer relationships, opposite-sex peer relationships, and the parent-child relationship for girls, but not boys. On the basis of these findings, it was concluded that perceived stress plays an intervening role in the relationship between self-esteem and different types of interpersonal relationships and that gender seems to be a moderator for some of the patterns of the relationships between these variables. These findings are discussed in light of the possible mechanisms by which the variables could influence each other. Implications for theory and practice as well as some directions for future research were also suggested.

    Active commuting - walking and bicycling for travel to and/or from work or educational addresses - may facilitate daily, routine physical activity. Several studies have investigated the relationship between active commuting and commuting stress; however, there are no studies examining the relationship between solely bicycle commuting and perceived stress, or studies that account for environmental determinants of bicycle commuting and stress. The current study evaluated the relationship between bicycle commuting, among working or studying adults in a dense urban setting, and perceived stress. A cross-sectional study was performed with 788 adults who regularly travelled to work or study locations (excluding those who only commuted on foot) in Barcelona, Spain. Participants responded to a comprehensive telephone survey concerning their travel behaviour from June 2011 through to May 2012. Participants were categorised as either bicycle commuters or non-bicycle commuters, and (based on the Perceived Stress Scale, PSS-4) as either stressed or non-stressed. Multivariate Poisson regression with robust variance models of stress status based on exposures with bicycle commuting were estimated and adjusted for potential confounders. Bicycle commuters had significantly lower risk of being stressed than non-bicycle commuters (Relative Risk; RR (95% CI)=0.73 (0.60 to 0.89), p=0.001). Bicycle commuters who bicycled 4 days per week (RR (95% CI)=0.42 (0.24 to 0.73), p=0.002) and those who bicycled 5 or more days per week (RR (95% CI)=0.57 (0.42 to 0.77), pstressed than those who bicycled less than 4 days. This relationship remained statistically significant after adjusting for individual and environmental confounders and when using different cut-offs of perceived stress. Stress reduction may be an important consequence of routine bicycle use and should be considered by decision makers as another potential benefit of its promotion. © Article author(s) (or their employer

    Living with a left ventricular assist device has significant psychosocial sequelae that affect health-related quality of life (HRQOL). The purpose of this study was to (1) describe psychosocial indicators of stress including perceived stress, depression, fatigue, and coping; (2) examine relationships among stress indicators by level of perceived stress; (3) examine relationships among indicators of stress and clinical outcomes; and (4) test the moderation of social support on the relationship between stress and clinical outcomes. Participants were recruited from 2 outpatient clinics in a cross-sectional study design. Standardized measures were self-administered via survey. Descriptive statistics, correlation, and multiple linear regression analysis were conducted. The sample (N = 62) was mostly male (78%), black (47%), and married (66%), with a mean age of 56.5 ± 13 years. The overall sample had a moderate stress profile: moderate perceived stress (mean, 11.7 ± 7), few depressive symptoms (mean, 3.2 ± 3.9), and moderate fatigue (mean, 14.3 ± 9.1). Increased perceived stress was associated with fatigue, depressive symptoms, and maladaptive coping (P stress and fatigue were significant correlates of overall HRQOL (adj. R = 0.41, P relationship between perceived stress and HRQOL, controlling for fatigue (R = 0.49, P stress have worse depressive symptoms, fatigue, and coping. The influence of high social support to improve the relationship between stress and HRQOL underscores the importance of a comprehensive plan to address psychosocial factors.

    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.

    There have been relatively few studies on the relationship between recent perceived environmental stress and cognitive performance, and the existing studies do not control for state anxiety during the cognitive testing. The current study addressed this need by examining recent self-reported environmental stress and divided attention performance, while controlling for state anxiety. Fifty-four university undergraduates who self-reported a wide range of perceived recent stress (10-item perceived stress scale) completed both single and dual (simultaneous auditory and visual stimuli) continuous performance tests. Partial correlation analysis showed a statistically significant positive correlation between perceived stress and the auditory omission errors from the dual condition, after controlling for state anxiety and auditory omission errors from the single condition (r = 0.41). This suggests that increased environmental stress relates to decreased divided attention performance in auditory vigilance. In contrast, an increase in state anxiety (controlling for perceived stress) was related to a decrease in auditory omission errors from the dual condition (r = - 0.37), which suggests that state anxiety may improve divided attention performance. Results suggest that further examination of the neurobiological consequences of environmental stress on divided attention and other executive functioning tasks is needed.

    Frontal glutamatergic synapses are thought to be critical for adaptive, long-term stress responses. Prefrontal cortices, including the anterior cingulate cortex (ACC) contribute to stress perception and regulation, and are involved in top-down regulation of peripheral glucocorticoid and inflammatory responses to stress. Levels of kynurenic acid (KYNA) in saliva increase in response to psychological stress, and this stress-induced effect may be abnormal in people with schizophrenia. Here we test the hypothesis that ACC glutamatergic functioning may contribute to the stress-induced salivary KYNA response in schizophrenia. In 56 patients with schizophrenia and 58 healthy controls, our results confirm that levels of KYNA in saliva increase following psychological stress. The magnitude of the effect correlated negatively with proton magnetic resonance spectroscopy (MRS) glutamate + glutamine (r = -.31, p = .017) and glutamate (r = -0.27, p = .047) levels in the ACC in patients but not in the controls (all p ≥ .45). Although, a causal relationship cannot be ascertained in this cross-sectional study, these findings suggest a potentially meaningful link between central glutamate levels and kynurenine pathway response to stress in individuals with schizophrenia.

    The mean and phase averaged pressure and wall shear stress distributions were measured on the stator wall of a 50% eccentric annular seal which was whirling in a circular orbit at the same speed as the shaft rotation. The shear stresses were measured using flush mounted hot-film probes. Four different operating conditions were considered consisting of Reynolds numbers of 12,000 and 24,000 and Taylor numbers of 3,300 and 6,600. At each of the operating conditions the axial distribution (from Z/L = -0.2 to 1.2) of the mean pressure, shear stress magnitude, and shear stress direction on the stator wall were measured. Also measured were the phase averaged pressure and shear stress. These data were combined to calculate the force distributions along the seal length. Integration of the force distributions result in the net forces and moments generated by the pressure and shear stresses. The flow field inside the seal operating at a Reynolds number of 24,000 and a Taylor number of 6,600 has been measured using a 3-D laser Doppler anemometer system. Phase averaged wall pressure and wall shear stress are presented along with phase averaged mean velocity and turbulence kinetic energy distributions located 0.16c from the stator wall where c is the seal clearance. The relationships between the velocity, turbulence, wall pressure and wall shear stress are very complex and do not follow simple bulk flow predictions.

    To study the relationship between occupational stress and psychological health state among oil workers. 1,230 oil workers in 122 work types of oil industry were selected and written occupational stress questionary(OSQ) and symptom check list (SCL-90). Petroleum workers' psychological health states were poor with increasing occupational stress degree. The scores in physical symptoms(1.87 +/- 0.80, 1.72 +/- 0.70), depression(1.74 +/- 0.76, 1.62 +/- 0.67), horror(1.48 +/- 0.65, 1.39 +/- 0.55) in the high and medium stress group were obviously higher than those in low stress group(1.55 +/- 0.61, 1.43 +/- 0.54, 1.28 +/- 0.46, respectively, P < 0.05). The score of mood state in the high and medium stress group was obviously higher than that in low stress group(P < 0.05). Psychological health states and mood state in the petroleum workers with short service length are significantly poorer than that with long service length(P < 0.01). Occupational stress should affect psychological health state of petroleum workers.

    To analyze the job burnout and mental health status of clinicians and the relationship of personality with job burnout and psychological stress, and to investigate the direct or indirect effects of personality on psychological stress. Maslach Burnout Inventory-General Survey (MBI-GS), Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RSC), and Kessler 10 Scale were administered to 775 clinicians. Of all clinicians, 29.5% had mild burnout, with a score of 22.7 ± 8.18 for psychological stress risk. The effect of personality on emotional exhaustion and cynicism was greater than that on personal accomplishment. Clinicians with a personality of introversion, neuroticism, and psychoticism suffered a higher risk of psychological stress. Personality had both direct and indirect effects on psychological stress. Neuroticism had the strongest effect on psychological stress, with an effect size of 0.55. Clinicians have a high level of both job burnout and mental psychological stress risk. Personality is significantly correlated with job burnout and psychological stress risk. Measures depending on personality should be taken for effective intervention.

    Objective: To investigate the relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease (ACVD). Methods: Serum levels of superoxide dismutases (SOD), malonaldehyde (MDA) (with biochemistry) interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and cortisol (with RIA) were measured in 32 patients with acute cerebrovascular disease (ACVD) plus stress complications and 48 patients without stress complications as well as 36 controls. Results: Serum SOD contents in non-stressed group were higher than those in stressed group (P<0.05) but lower than those of the controls (P<0.05). However the levels of MDA, IL-6, TNF-α and cortisol were highest in the stressed group and lowest in the controls (all P<0.05). Conclusion: Oxygen free radicals, IL-6, TNF-α and cortisol were involved in stress complications in patients with ACVD. Monitoring the levels of serum SOD, MDA, IL-6, TNF-α and cortisol could be useful for predicting stress complications and evaluating the therapeutic effect. (authors)

    Emotional intelligence (EI) theory provides a view about predicting effective factors in people's lives whether in education or profession. According to earlier studies, people who have higher emotional skills are more successful in many of life aspects :e.g., reaction to stress and controlling stress situations. Since students are the future of society, this study was carried out to evaluate the relationship between EI and education stress in the students of Birjand University of Medical Sciences (BUMS). In this cross-sectional study, 260 students were selected by proportional sampling in four faculties: Medicine, Nursing and Midwifery, Paramedical Sciences, and Health. Data were collected using two questionnaires: The standardized EI Shering's (33 questions, five domains) and the Student-Life Stress Inventory (57 questions, nine domains). The obtained data were analyzed by independent t-test, Pearson's correlation coefficient, and linear regression at the significant level of α = 0.05. Totally, 65.8% of participants were females and 31.1% were males. The educational level of the participants included Associate's degree (44.6%) Bachelor's degree in science (31.2%), and medical science (23.1%). There was no significant correlation between EI scores and educational stress in students. But there was a significant relationship between EI with sex (P = 0.02) and mean of EI scores with three domains of academic stress: Personal favorites (P = 0.004), reaction to stressors (P = 0.002), and performance in stressful situations (P = 0.001). Although EI growth in different individuals can promote their success, it cannot decrease academic stress by itself which was particularly significant in females. Therefore, other causes of stress such as individual differences must be taken into consideration.

    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

    Once high levels of work-related stress among teachers were confirmed many studies concentrated on identifying and investigating key stress factors among school teachers. Unfortunately there are very few researches made on stress causing factors among teachers in Republic of Macedonia. To determine the most frequent stress causing factors among teachers in elementary schools and to investigate their relationship with demographic and job characteristics. We performed a descriptive-analytical model of a cross-sectional study which involved 300 teachers employed in nine elementary schools. Evaluation of examined subjects included completion of a specially designed questionnaire. Among six categories of factors that generate work related stress (job demands, control, relationships, role, changes and support) control and support had the highest mean scores. Within the control category the highest levels of perceived teacher's work-related stress were caused by the following factors - changes in terms and conditions without consultation and given responsibility without the authority to take decisions. 141 out of the interviewed teachers (47%) have mentioned changes in terms and conditions without consultation as very stressful, while another 50 (16.67%) have reported it as stressful. 123 out of interviewed teachers (41%) have stated given responsibility without the authority to take decisions as very stressful, with another 105 (35%) have reported it as stressful. In the category support the highest levels of perceived teacher's work-related stress were caused by stress factors - lack of funds/resources to do the job and limited or no access to training. Out of 300 interviewed teachers, 179 (59.67%) have reported lack of funds/resources to do the job as very stressful, while another 50 (16.67%) as stressful. There is no significant relationship between the stress factor limited or no access to training and demographic and job characteristics. Our findings confirm that

    The purpose of this note is to describe a relationship between hardness and flow stress for the ordered L1$sub 2$ phase Zr$sub 3$Al, a possible structural material for use in nuclear power reactors. Experimental data obtained with the Zr-8.9% Al alloy lead to the conclusion that the hardness of polycrystalline Zr$sub 3$Al obeys an expression of the Hall-Petch form. When combined with a similar expression for flow stress, established previously, a simple relationship is obtained for flow stress in terms of hardness of well annealed material. Hardness measurements thus provide a rapid and inexpensive assessment of the strength of Zr$sub 3$Al. 8 refs

    Structural equation modeling was used to test a model in which positive affect, negative affect, perceived stress, and social support were hypothesized to mediate the relationship between forgiveness and mental and physical health. Six hundred and twenty-three undergraduates completed a battery of self-report measures. Results of the analyses indicated that the forgiveness-health relation was mediated by positive affect, negative affect, stress, and the interrelationship between negative affect and stress. There was limited support for social support and the interrelationship between positive affect and social support as mediators. The results suggested that the relationship between forgiveness and health is mediated rather than direct. Implications and directions for future research are discussed.

    This report evaluates the direct tensile strength and an equivalent uniaxial tensile stress-strain relationship for prestressed concrete using data from specimens tested at the University of Alberta which represent segments from the wall of a containment vessel. The stress-strain relationship, when used in conjunction with the BOSOR5 program, enables prediction of the response of prestressed concrete under any biaxial combination of compressive and/or tensile stresses. Comparisons between the experimental and analytical (BOSOR5) load-strain response of the wall segments are also presented. It is concluded that the BOSOR5 program is able to predict satisfactorily the response of the wall segments and multi-layered shell structures. (author)

  19. Stress Exposure in Significant Relationships Is Associated with Lymph Node Status in Breast Cancer.

    Full Text Available Life stress exposure may impact on health and disease. Previous literature showed that stressful life events are associated with cancer incidence, survival and mortality. In animal models, patterns of maternal care have been shown to critically affect stress sensitivity and immunity trajectories later in life, by modifying DNA methylation during critical periods early in life. However, the role of parental care in breast cancer progression and survival has only limitedly been explored. Here, we investigated whether these factors may be linked to biological prognostic variables.One hundred twenty-three women hospitalized for surgery of primary breast cancer completed a questionnaire assessing parental bonding. Stressful events throughout the life span were also assessed.We found that the absence of optimal parental relationships is significantly associated with an increased risk of lymph node involvement, adjusting for confounders, while cumulative stress in the area of sentimental relationships is borderline significantly associated with the same prognostic factor.Our results suggest that parental bonding and sentimental relations may have a role in breast cancer progression. These variables represent an important evolutionary aspect which may modulate cancer progression through psycho-physiological stress pathways and influence the immune system.

    This study examined the moderating role of contingent self-worth on the relationships between school stressors and psychological stress responses among Japanese adolescents. A total of 371 Japanese junior high school students (184 boys and 187 girls, M age  = 12.79 years, SD = 0.71) completed the Japanese version of the Self-Worth Contingency Questionnaire and a mental health checklist at two points separated by a two-month interval. Hierarchical multiple regression analyses were then used to determine whether contingent self-worth moderated the relationship between school stressors and psychological stress responses. The results indicated that, when psychological stress responses were controlled for at Time 1, contingent self-worth did not predict the psychological stress responses at Time 2. However, a two-way interaction between contingent self-worth and stressors was found to significantly influence psychological stress responses, thus indicating that stressors had a stronger impact on psychological stress responses among those with high contingent self-worth compared to those with low contingent self-worth.

    Although increased reactive oxygen species (ROS) is caused by stress accelerates collagen degradation, there was no data on the relationship between stress and urinary hydroxyproline (Hyp) and proline (Pro), a good marker of collagen degradation. The purpose of this study was to evaluate the relationship between depression, anxiety, and stress (DAS) and concentrations of urinary Hyp and Pro. 97 hospital employees aged 20 to 58 were asked to fill out comprehensive self-administrated questionnaires containing information about their medical history, lifestyle, length of the work year, shift-work and DAS. depression anxiety stress scale (DASS) was applied to evaluate chronic mental disorders. Urine samples were analyzed using high performance liquid chromatography (HPLC) with double derivatization for the assay of hydroxyproline and proline. The mean value of Hyp and Pro concentration in all subjects was 194.1 ± 113.4 μmol/g and 568.2 ± 310.7 μmol/g. DASS values and urinary Pro concentrations were differentiated by sex (female > male, p others, p < 0.05). In the stepwise multiple linear regressions, urinary Hyp and Pro concentrations were influenced by stress (Adjusted r2 = 0.051) and anxiety and job (Adjusted r2 = 0.199), respectively. We found that stress and anxiety were correlated with urinary Hyp and Pro concentrations. To identifying a definite correlation, further study in large populations will be needed.

    Exposure to highly palatable foods may increase eating in response to stress, but this behavioral response has not been examined in relation to the neighborhood food environment. This study examined whether the neighborhood food environment modified relationships between psychosocial stress and dietary behaviors. Probability-sample survey (n=460) and in-person food environment audit data were used. Dietary behaviors were measured using 17 snack food items and a single eating-out-of-home item. Chronic stress was derived from five subscales; major life events was a count of nine items. The neighborhood food environment was measured as availability of large grocery stores, small grocery stores, and convenience stores, as well as proportion of restaurants that were fast food. Two-level hierarchical regression models were estimated. Snack food intake was positively associated with convenience store availability and negatively associated with large grocery store availability. The measures of chronic stress and major life events were generally not associated with either dietary behavior overall, although Latinos were less likely to eat out at high levels of major life events than African Americans. Stress-neighborhood food environment interactions were not statistically significant. Important questions remain regarding the role of the neighborhood food environment in the stress-diet relationship that warrant further investigation. Copyright © 2013 Elsevier Ltd.

    Most lesbian, gay, and bisexual (LGB) people want a stable, satisfying romantic relationship. Although many of the predictors of relationship outcomes are similar to those of heterosexual couples, same-sex couples face some additional challenges associated with minority stress that also impact upon relationship quality. Here, we investigate the association between minority stressors and relationship quality in a sample of 363 adults (M age = 30.37, SD = 10.78) currently in a same-sex romantic relationship. Internalized homophobia and difficulties accepting one's LGB identity were each negatively associated with relationship satisfaction via heightened concealment motivation. We also examined the protective role of identity affirmation on relationship quality, finding a direct positive relationship between the two variables. Minority stressors were negatively associated with couple relationship satisfaction via heightened concealment motivation. The finding that identity affirmation directly predicted increased couple satisfaction also highlights the important role of protective factors in same-sex couple relationships. © 2018 Family Process Institute.

    Stress analysis with X-ray diffraction (XRD) for hexagonal polycrystalline materials in the Laue classes 6/mmm and 6/m has been studied on the basis of the crystal symmetry of the constituent crystallites which was proposed by R. Yokoyama and J. Harada ['Re-evaluation of formulae for X-ray stress analysis in polycrystalline specimens with fibre texture', Journal of Applied Crystallography, Vol.42, pp.185-191 (2009)]. The relationship between the stress and strain observable by XRD in a hexagonal polycrystalline material with [0001] fibre texture was formulated in terms of the elastic compliance defined for its single crystal. As a result, it was shown that the average strains obtained in the crystallites for both symmetries of 6/mmm and 6/m are different from each other under the triaxial or biaxial stress field. Then, it turned out that the line width of XRD changes depending on the measurement direction. (author)

    Full Text Available Abstract Background The purpose of this study was to investigate the relationship among work stress, sex life satisfaction, and mental health of married nurses. Demographic information, work stress, sex life satisfaction, sexual desire and mental health measured using the Chinese Health Questionnaire, data were collected from 100 married nurses in Taiwan. Findings Sex life satisfaction and age were negatively correlated, but sex life satisfaction and sexual desire were positively correlated. The mental health of over-committed nursing staff was not affected. Higher reward for effort was positively correlated with sex life satisfaction. Conclusions No matter whether job stress was high or low, receiving a higher reward for effort led to better sex life satisfaction, which had a satisfying positive effect on the nurses' lives. To improve nursing care quality at the hospital, nursing administrators should assist nurses in confronting work stress via positive adjustment, which is associated with the nurses’ sexual harmony, and quality of life.

    Four-point bending tests were made on rectangular isotropic 7477PT graphite specimens of different sizes to observe the relation between load and outermost fiber strain. Analytical methods, allowing for nonlinear stress-strain relationships different between tension and compression, were developed for calculating the fiber stress distribution in a beam and the failure probability based on the Weibull statistical theory for bending fracture. With increase of the stress, the stress-strain curves for tension deviate from the linearity and also from those for compression. The true bending strengths of the rectangular bars are 10 -- 20 percent lower than elastic bending strengths. Revised Weibull theory gives failure probability distributions agreeing with measured ones, compared with the theory based on elastic behavior. (auth.)

    The first year of parenthood can be a stressful time, especially for high-risk couples. Symptoms of posttraumatic stress (PTS) have been associated with decreased intimacy, communication, and relationship adjustment, yet there is a lack of research on how PTS symptoms might affect couples in early parenthood. Furthermore, there is little evidence regarding the way in which PTS symptoms may affect couples above and beyond known risk factors such as intimate partner violence (IPV) and harmful alcohol use. The current study investigated how PTS symptoms were related to new parents' relationship satisfaction in the context of IPV and harmful drinking. Ninety-eight heterosexual couples filled out questionnaires 1 year after the birth of their first child. Hierarchical multiple regression analyses indicated that, for men, PTS symptoms predicted lower relationship satisfaction over and above IPV victimization and harmful drinking. However, for women, psychological IPV victimization was the only significant multivariate predictor. In addition, for men, PTS symptoms interacted with harmful drinking to predict poorer relationship satisfaction. The results suggest that women's relationship satisfaction is particularly linked to psychological IPV victimization during early parenthood, whereas men's relationship satisfaction is particularly associated with their own harmful drinking and PTS symptoms. Implications are discussed.

    Fear of crime is a growing social and public health problem globally, including in developed countries such as Sweden. This study investigated the impact of fear of crime on self-reported health and stress among men living in Gävleborg County. The study used data collected from 2993 men through a cross sectional survey in the 2014 Health in Equal Terms survey. Descriptive and logistic regression analyses were carried out to study the relationship between fear of crime and self-reported health and stress. There was a statistically significant association between fear of crime and self-reported poor health and stress among men residing in Gävleborg County. In the bivariate analysis, men who reported fear of crime had odds of 1.98 (CI 1.47-2.66) and 2.23 (CI 1.45-3.41) respectively. Adjusting for demographic, social and economic variables in the multivariate analysis only reduced the odds ratio for self-reported poor health to 1.52 (CI 1.05-2.21) but not for self-reported stress with odds of 2.22 (1.27-3.86). Fear of crime among men was statistically significantly associated with self-reported poor health and stress in Gävleborg County. However, the statistically significant relationship remained even after accounting for demographic, social and economic factors, which warrants further research to better understand the role played by other variables.

    The relationship between increased serum enzyme activity of prolidase and increased rate of collagen turnover in the arterial wall has been asserted in previous studies. Collagen reflects much of the strength to the connective tissue involved in the arterial wall. Atherosclerosis is very common vessel disease and oxidative stress plays a pivotal role in the etiopathogenesis. Our objective was to examine the serum enzyme activity of prolidase and its possible relationships with oxidative stress parameters in obese subjects. Our present study was conducted 27 obese subjects and 26 age-matched healthy control subjects. The serum enzyme activity of prolidase in all study population was evaluated spectrophotometrically. Oxidative stress levels in obese subjects were analyzed with total antioxidant capacity (TAC) and total oxidant status (TOS) as well as oxidative stress index (OSI). Obese subjects have higher serum TOS and OSI indicators as well as prolidase activity than those in control subjects (for all; pstress levels in obese subjects. The significantly correlation between increased oxidative stress and increased prolidase activity may play a pivotal role in etiopathogenesis of atherosclerotic cardiovascular diseases in obese subjects.

    The goal of the study described here was to examine the interrelationship between psychological factors (anxiety, stress, and depression) and seizures. In this longitudinal cohort study, data on anxiety, depression, perceived stress, and seizure recency (time since last seizure) and frequency were collected at two time points using standard validated questionnaire measures. Empirically based models with psychological factors explaining change in (1) seizure recency and (2) seizure frequency scores across time were specified. We then tested how these psychological factors acted together in predicting seizure recency and frequency. Our data were used to test whether these models were valid for the study population. Latent variable structural equation modeling was used for the analysis. Four hundred thirty-three of the 558 individuals who initially consented to participate provided two waves of data for this analysis. Stress (beta=0.25, Panxiety (beta=0.30, Pdepression (beta=0.30, Pdepression that mediated the relationship of both anxiety and stress with modeled change in seizure recency (beta=0.19, PDepression mediates the relationship between stress and anxiety and change in seizure recency and seizure frequency. These findings highlight the importance of depression management in addition to seizure management in the assessment and treatment of epilepsy in an adult population.

    We examined whether romantic relationship satisfaction would serve as a link between early and later stressors which in turn would influence the Thyroid Function Index (TFI), an indicator of physiological stress response. Using the framework of genetic susceptibility theory combined with hypotheses derived from the vulnerability-stress-adaptation and stress-generation models, we tested whether the hypothesized mediational model would be conditioned by 5-HTTLPR genotype, with greater effects and stronger evidence of mediation among carriers of the “s” allele. In a sample of African American women in romantic relationships (n = 270), we found that 5-HTTLPR moderated each stage of the hypothesized mediational model in a “for better or for worse” manner. That is genetic polymorphisms function to exacerbate not only the detrimental impact of negative environments (i.e. “for worse effects”) but also the beneficial impact of positive environments (i.e. “for better effects”). The effect of early stress on relationship satisfaction was greater among carriers of the “short” allele than among those who did not carry the short allele, and was significantly different in both the “for better” and “for worse” direction. Likewise, the effect of relationship satisfaction on later stressors was moderated in a “for better” or “for worse” manner. Finally, impact on physiological stress, indexed using TFI level, indicated that the impact of later stressors on TFI level was greater in the presence of the short allele, and also followed a “for better” or “for worse” pattern. As expected, the proposed mediational model provided a better fit for “s” allele carriers. PMID:26376424

    The present study examined associations between stress and problematic alcohol use among US Navy members anticipating deployment, whether depressive symptoms mediated the stress-alcohol link, and whether social support and relationship satisfaction moderated associations between stress, depressive symptoms, and problematic alcohol use. Participants were 108 US Navy members assigned to an Arleigh Burke-class destroyer anticipating an 8-month deployment after Operational Enduring Freedom/Operation Iraqi Freedom. Stress was indirectly related to problematic alcohol use such that higher levels of stress were associated with higher levels of depressive symptoms, which were further associated with higher levels of alcohol use. The indirect effect of stress to problematic alcohol use via depressive symptoms was tested at different levels of social support and relationship satisfaction. At higher levels of social support and relationship satisfaction, the association between stress and problematic alcohol use via depressive symptoms decreased. Results help identify targets for alcohol prevention efforts among current military members.

    Conclusion The results of this study showed that parent-child stress had a significant effect on developmental skills of children with cochlear implants. Due to the importance of developmental skills in children with cochlear implants, the results of this study warned the need to provide counseling and psychological support for this group of parents. Accordingly, the programs should be offered in the form of workshops for mothers of these children. Also, psychologists and family counselors and experts in family therapy are recommended to have special attention to the role of stress in parent-child relationships in treatment programs and training.

    The maximum diameter (MD) criterion is the most important factor when predicting risk of rupture of abdominal aortic aneurysms (AAAs). An elevated wall stress has also been linked to a high risk of aneurysm rupture, yet is an uncommon clinical practice to compute AAA wall stress. The purpose of this study is to assess whether other characteristics of the AAA geometry are statistically correlated with wall stress. Using in-house segmentation and meshing algorithms, 30 patient-specific AAA models were generated for finite element analysis (FEA). These models were subsequently used to estimate wall stress and maximum diameter and to evaluate the spatial distributions of wall thickness, cross-sectional diameter, mean curvature, and Gaussian curvature. Data analysis consisted of statistical correlations of the aforementioned geometry metrics with wall stress for the 30 AAA inner and outer wall surfaces. In addition, a linear regression analysis was performed with all the AAA wall surfaces to quantify the relationship of the geometric indices with wall stress. These analyses indicated that while all the geometry metrics have statistically significant correlations with wall stress, the local mean curvature (LMC) exhibits the highest average Pearson's correlation coefficient for both inner and outer wall surfaces. The linear regression analysis revealed coefficients of determination for the outer and inner wall surfaces of 0.712 and 0.516, respectively, with LMC having the largest effect on the linear regression equation with wall stress. This work underscores the importance of evaluating AAA mean wall curvature as a potential surrogate for wall stress.

    Glucocorticoids are hormones that mediate the energetic demands that accompany environmental challenges. It is therefore not surprising that these metabolic hormones have come to dominate endocrine research on the health and fitness of wild populations. Yet, several problems have been identified in the vertebrate research that also apply to the non-human primate research. First, glucocorticoids should not be used as a proxy for fitness (unless a link has previously been established between glucocorticoids and fitness for a particular population). Second, stress research in behavioral ecology has been overly focused on "chronic stress" despite little evidence that chronic stress hampers fitness in wild animals. Third, research effort has been disproportionately focused on the causes of glucocorticoid variation rather than the fitness consequences. With these problems in mind, we have three objectives for this review. We describe the conceptual framework behind the "stress concept", emphasizing that high glucocorticoids do not necessarily indicate a stress response, and that a stress response does not necessarily indicate an animal is in poor health. Then, we conduct a comprehensive review of all studies on "stress" in wild primates, including any study that examined environmental factors, the stress response, and/or fitness (or proxies for fitness). Remarkably, not a single primate study establishes a connection between all three. Finally, we provide several recommendations for future research in the field of primate behavioral endocrinology, primarily the need to move beyond identifying the factors that cause glucocorticoid secretion to additionally focus on the relationship between glucocorticoids and fitness. We believe that this is an important next step for research on stress physiology in primates. Copyright © 2017 Elsevier Inc. All rights reserved.

    Women in menopause have the more mood swings than before menopause. At the same time seem to sexual self-concept and sexual aspects of self-knowledge has a great impact on their mental health. This study aimed to investigate the sexual self-concept and its relationship to depression, stress and anxiety in postmenopausal women's. In this descriptive correlation research, 300 of postmenopausal women referred to healthcare and medical treatment centers in Abadeh city were selected by convenience sampling method. The information in this study was collected by using questionnaires of multidimensional sexual self-concept and depression anxiety stress scale 21 (DASS-21). For data analysis, SPSS/17 software was used. The results showed the mean score positive sexual self-concept was 41.03 ± 8.66 and the average score of negative sexual self in women's was 110.32 ± 43.05. As well as scores of depression, stress, and anxiety, 35.67%, 32.33% and 37.67% respectively were in severe level. Positive and negative sexual self-concept scores with scores of stress, anxiety, and depression, of post-menopausal women in the confidence of 0.01, is significantly correlated ( P stress, anxiety, and depression in severe level and also a significant correlation between increased stress, anxiety and depression with negative and weak self-concept of women's, it is necessary to devote more careful attention to mental health issues of women's and have appropriate interventions.

    The purpose of this study was to conduct a confirmatory factor analytic investigation of the Femininity Ideology Scale (FIS) and to assess whether feminine gender role stress mediated the relationship between femininity ideology and anxiety. During the 2010-2011 academic year, a convenience sample of 606 college women were recruited from three universities and one college. Confirmatory factor analysis supported a four- versus the hypothesized five-factor model, resulting in the elimination of the Dependency/Deference factor. Mediation analysis using structural equation modeling indicated no direct relationship between Femininity Ideology and Anxiety, although an indirect one was observed, mediated through Feminine Gender Role Stress. The results are discussed in terms of possible changes in contemporary notions of femininity, and the utility of using the FIS in applied therapeutic settings.

    Over a century of behavioral research has shown that stress can enhance or impair learning and memory. In the present review, we have explored the complex effects of stress on cognition and propose that they are characterized by linear and non-linear dose-response functions, which together reveal a hormetic relationship between stress and learning. We suggest that stress initially enhances hippocampal function, resulting from amygdala-induced excitation of hippocampal synaptic plasticity, as ...

    The prevalence of adolescent overweight is significant, almost 25% in some minorities, and often is associated with depressive symptoms. Psychological and psychosocial factors as well as poor coping skills have been correlated with unhealthy eating and obesity. The purpose of this study was to examine relationships among self-esteem, stress, social support, and coping; and to test a model of their effects on eating behavior and depressive mood in a sample of 102 high school students (87% minority). Results indicate that (a) stress and low self-esteem were related to avoidant coping and depressive mood, and that (b) low self-esteem and avoidant coping were related to unhealthy eating behavior. Results suggest that teaching adolescents skills to reduce stress, build self-esteem, and use more positive approaches to coping may prevent unhealthy eating and subsequent obesity, and lower risk of depressive symptoms. 2008 Wiley Periodicals, Inc.

    Design and Methods: The study used data collected from 2993 men through a cross sectional survey in the 2014 Health in Equal Terms survey. Descriptive and logistic regression analyses were carried out to study the relationship between fear of crime and self-reported health and stress. Results: There was a statistically significant association between fear of crime and self-reported poor health and stress among men residing in Gävleborg County. In the bivariate analysis, men who reported fear of crime had odds of 1.98 (CI 1.47- 2.66 and 2.23 (CI 1.45-3.41 respectively. Adjusting for demographic, social and economic variables in the multivariate analysis only reduced the odds ratio for self-reported poor health to 1.52 (CI 1.05-2.21 but not for self-reported stress with odds of 2.22 (1.27-3.86. Conclusions: Fear of crime among men was statistically significantly associated with self-reported poor health and stress in Gävleborg County. However, the statistically significant relationship remained even after accounting for demographic, social and economic factors, which warrants further research to better understand the role played by other variables.

    Changes in the UK community pharmacy profession including new contractual frameworks, expansion of services, and increasing levels of workload have prompted concerns about rising levels of workplace stress and overload. This has implications for pharmacist health and well-being and the occurrence of errors that pose a risk to patient safety. Despite these concerns being voiced in the profession, few studies have explored work stress in the community pharmacy context. To investigate work-related stress among UK community pharmacists and to explore its relationships with pharmacists' psychological and physical well-being, and the occurrence of self-reported dispensing errors and detection of prescribing errors. A cross-sectional postal survey of a random sample of practicing community pharmacists (n = 903) used ASSET (A Shortened Stress Evaluation Tool) and questions relating to self-reported involvement in errors. Stress data were compared to general working population norms, and regressed on well-being and self-reported errors. Analysis of the data revealed that pharmacists reported significantly higher levels of workplace stressors than the general working population, with concerns about work-life balance, the nature of the job, and work relationships being the most influential on health and well-being. Despite this, pharmacists were not found to report worse health than the general working population. Self-reported error involvement was linked to both high dispensing volume and being troubled by perceived overload (dispensing errors), and resources and communication (detection of prescribing errors). This study contributes to the literature by benchmarking community pharmacists' health and well-being, and investigating sources of stress using a quantitative approach. A further important contribution to the literature is the identification of a quantitative link between high workload and self-reported dispensing errors. Copyright © 2014 Elsevier Inc. All rights

  16. Child-Care Instability and Behavior Problems: Does Parenting Stress Mediate the Relationship?

    Pilarz, Alejandra Ros; Hill, Heather D

    2017-10-01

    Child care instability is associated with more behavior problems in young children, but the mechanisms of this relationship are not well understood. Theoretically, this relationship is likely to emerge, at least in part, because care instability leads to increased parenting stress. Moreover, low socioeconomic status and single-mother families may be more vulnerable to the effects of instability. This study tested these hypotheses using data from the Fragile Families and Child Wellbeing study (n=1,675) and structural equation modeling. Three types of child care instability were examined: long-term instability, multiplicity, and needing to use back-up arrangements. Overall, findings showed little evidence that parenting stress mediated the associations between care instability and child behavior problems among the full sample. Among single-mother and low-income families, however, needing to use back-up arrangements had small positive associations with parenting stress, which partially mediated the relationship between that type of care instability and child externalizing behavior problems.

    Relationship dissolution is a distressing experience which can result in the emergence of posttraumatic stress (i.e. post-dissolution PTSS) and other psychological symptoms among college students. Little is known, however, whether posttraumatic stress cognitions and interpersonal dependency may influence the severity of these distress outcomes. This study examined the interrelationship between posttraumatic stress symptoms (PTSS), posttraumatic stress cognitions, interpersonal dependency and psychological co-morbidities following relationship dissolution. One hundred and eighty college students (M = 69, F = 111) who had experienced relationship dissolution completed the Posttraumatic Stress Diagnostic Scale, Posttraumatic Stress Cognition Inventory, Interpersonal Dependency Inventory and General Health Questionnaire-28. Posttraumatic stress symptoms following relationship dissolution (post-dissolution PTSS) were associated with increased psychological co-morbidities. Negative view of oneself and self-blame mediated between PTSS and psychological co-morbidities. Assertion of autonomy moderated the mediational effects of negative cognitions on psychological co-morbidities. People can develop PTSSs and other psychological symptoms following the dissolution of a romantic relationship. Their concept of self and tendency to seek independence and control played a key role in determining the severity of distress symptoms.

    To explore the interrelationship and mediating effect of factors that are beneficial (i.e., antioxidants) and harmful (i.e., inflammation and oxidative stress) to the relationship between sleep and cardiometabolic health. Cross-sectional data from the 2005-2006 National Health and Nutrition Examination Survey. Nationally representative population sample from the US. Age ≥ 20 y with sleep data; final analytical sample of n = 2,079. N/A. Metabolic syndrome was classified according to the Joint Interim Statement, and sleep duration was categorized as very short, short, adequate, and long sleepers (≤ 4, 5-6, 7-8, and ≥ 9 h per night, respectively). The indirect mediation effect was quantified as large (≥ 0.25), moderate (≥ 0.09), modest (≥ 0.01), and weak (sleep duration categories, whereas oxidative stress was elevated among short and very short sleepers. Select sleep duration- cardiometabolic health relationships were mediated by C-reactive protein (CRP), γ-glutamyl transferase (GGT), carotenoids, uric acid, and vitamins C and D, and were moderated by sex. Specifically, moderate-to-large indirect mediation by GGT, carotenoids, uric acid, and vitamin D were found for sleep duration-waist circumference and -systolic blood pressure relationships, whereas vitamin C was a moderate mediator of the sleep duration-diastolic blood pressure relationship. Several factors related to inflammation, oxidative stress, and antioxidant status were found to lie on the casual pathway of the sleep duration-cardiometabolic health relationship. Further longitudinal studies are needed to confirm our results. © 2015 Associated Professional Sleep Societies, LLC.

    To identify the relationship of work stress and family stress to the health of women in Korea. Cross-sectional study. Three hundred and thirty-one married women working in 14 manufacturing companies in Korea. Subjects responded to a questionnaire that included items on work stress, family stress, social support, and general characteristics. Perceived health status (PHS) was assessed with the Short Form-36. There was a significant positive relationship between social support and PHS, but significant negative relationships were found between PHS and work stress as well as family stress. Hierarchical multiple regression analysis explained the health status of married working women by four categories: personal, work related, family related, and social support, and accounted for 45.4% of the variance. When family-related factors were added to the model, the power of explanation was increased by 17.9% compared with the explained variance. Family stress was a major variable not only for explaining the variance but also for correlating with health status. Both work stress and family stress should be considered together when addressing the health of working women in the industrial sector in Korea.

    Black women in the Deep South experience excess morbidity/mortality from obesity-related diseases, which may be partially attributable to poor diet. One reason for poor dietary intake may be high stress, which has been associated with unhealthy diets in other groups. Limited data are available regarding dietary patterns of black women in the Deep South and to our knowledge no studies have been published exploring relationships between stress and dietary patterns among this group. This cross-sectional study explored the relationship between stress and adherence to food group recommendations among black women in the Deep South. Participants (n = 355) provided demographic, anthropometric, stress (PSS-10), and dietary (NCI ASA-24 hour recall) data. Participants were obese (BMI = 36.5 kg/m(2)) and reported moderate stress (PSS-10 score = 16) and minimal adherence to Dietary Guidelines for Americans food group recommendations (1/3 did not meet recommendations for any food group). Participants reporting higher stress had higher BMIs than those reporting lower stress. There was no observed relationship between stress and dietary intake in this sample. Based on these study findings, which are limited by potential misreporting of dietary intake and limited variability in stress measure outcomes, there is insufficient evidence to support a relationship between stress and dietary intake.

    2010-01-01

    The effects of perceived stress (PS) on the relationship between adaptive and maladaptive forms of perfectionism and burnout were examined. Smith's (1986)stress appraisal model and Kelley, Eklund, and Ritter-Taylor's (1999) model of coach burnout were used to test two models of burnout in a sample of college coaches (N=177). The results indicated that there is an indirect effect of self-evaluative perfectionism (i.e., maladaptive form of perfectionism) on burnout through PS as well as a significant direct link to burnout, accounting for 56% of its variance. In contrast, conscientious perfectionism (CP) (i.e., adaptive perfectionism) did not directly impact burnout, nor was there an indirect effect through PS. Based on Lazarus's (1999) ideas about stress appraisal, the results suggested that maladaptive forms of perfectionism resulted in more threatening perceptions of stress, thus, potentially leading to the experience of burnout. However, adaptive forms of perfectionism did not seem to result in increased appraisals of stress or result in burnout. The results did indicate a significant correlation between the two forms of perfectionism, which may explain why CP did not significantly impact PS or burnout.

    This paper presents an experimental investigation of two different magnetorheological (MR) fluids, namely, water-based and hydrocarbon-based MR fluids in compression mode under various applied currents. Finite element method magnetics was used to predict the magnetic field distribution inside the MR fluids generated by a coil. A test rig was constructed where the MR fluid was sandwiched between two flat surfaces. During the compression, the upper surface was moved towards the lower surface in a vertical direction. Stress-strain relationships were obtained for arrangements of equipment where each type of fluid was involved, using compression test equipment. The apparent compressive stress was found to be increased with the increase in magnetic field strength. In addition, the apparent compressive stress of the water-based MR fluid showed a response to the compressive strain of greater magnitude. However, during the compression process, the hydrocarbon-based MR fluid appeared to show a unique behaviour where an abrupt pressure drop was discovered in a region where the apparent compressive stress would be expected to increase steadily. The conclusion is drawn that the apparent compressive stress of MR fluids is influenced strongly by the nature of the carrier fluid and by the magnitude of the applied current

    Full Text Available Most research finds socio-psychological aspects and the organism-environment relationship crucial in the onset of stress-related phenomena; equally important is the subject’s evaluation of stimuli. The Burnout syndrome is defined as a psychological state perceived as emotive breakdown and sense of depersonalization, featuring decreased effectiveness at work and a lower evaluation of one’s performance. At school, the most significant widespread stressors are issues in managing student behavior. However, in the literature few works treat stress and burnout as a specific function of the teacher-pupil relationship. This research will highlight the significant correlations existing between burnout, self-efficacy, students’ academic performance and the quality of pupil-teacher relationships. 37 primary-school teachers in north-west Italy were involved (age range: 27-57 yrs; M=44.76 yrs; SD=8.38 yrs. Tools used were a specially designed socio-personal questionnaire, the Maslach Burnout Inventory (M.B.I. and the Classroom and School Context Teacher Self-Efficacy Scale (CSC-TSES, while teachers’ perception of the relationship with their pupils was investigated with STRS (Italian adaptation. Preliminary analysis reveals mutual influence between teachers' self-efficacy levels and degree of burnout; Conflict is the only dimension correlating significantly with burnout levels and self-efficacy in class management ability

    The association between depression, anxiety, and stress among Arab menopause and postmenopausal women have been explored in detailed. The objective of this study was to determine the correlation between depression, anxiety, and stress in menopausal and postmenopausal women and shedding more light on a complex relationship. A cross-sectional descriptive study was used to generate menopause symptoms experienced by Arabian women at the primary health care centers in Qatar. A representative sample of 1468 women aged 45-65 years were approached during July 2012 and May 2014 and 1101 women agreed to participate (75.0%) and responded to the study. Depression, anxiety, and stress were measured using the Depression Anxiety Stress Scales 21. Data on body mass index (BMI), clinical and other parameters were used. Univariate, multivariate, and matrix correlation analysis were performed for statistical analysis. A total of 1101 women agreed to participate after informed consent was obtained. The mean age and standard deviation (SD) of the menopausal age were 49.55 (3.12), the mean and SD of postmenopausal age was 58.08 (3.26) ( P stress among menopause and postmenopause. The multivariate regression analyses revealed that age in years, diastolic BP, consanguinity, regular exercise were a predictor for depression. Meanwhile, diastolic BP, occupation, and physical activity considered the main risk factors for anxiety. Furthermore, age in years, occupation, and sheesha smoking habits were considered as the main risk factors associated with stress. A large number of factors were associated with experiencing menopausal and psycho-social problems and which had negative effects on the quality of life among Arabian women. Depression, anxiety, and stress should be considered as important risk factors for osteoporosis.

    Acculturative stress prevents international students from adapting to the host culture, increasing their risk for depression. International students in China are a growing and at-risk population for acculturative stress and depression. With data from the International Student Health and Behaviour Survey (Yu et al., ) in China, seven acculturative stress components were detected in a previous study (Yu et al., ), including a central component (self-confidence), three distal components (value conflict, identity threat and rejection) and three proximal components (poor cultural competence, opportunity deprivation and homesickness). The current study extended the previous study to investigate the relationship between these components and depression with data also from International Student Health and Behaviour Survey. Participants were 567 students (59% male, 40.4% African, mean age = 22.75, SD = 4.11) recruited in Wuhan, China. The sample scored high on the Acculturative Stress Scale for International Students (M = 92.81, SD = 23.93) and Center for Epidemiologic Studies Short Depression Scale (M = 0.97, SD = 0.53). Acculturative stress was positively associated with depression; the association between the three distal stress components and depression was fully mediated through self-confidence, while the three proximal components had a direct effect and a self-confidence-mediated indirect effect. These findings extended the value of the previous study, highlighted the central role of self-confidence in understanding acculturative stress and depression and provided new data supporting more effective counselling for international students in China.

    Previous studies have suggested that meaning in life may buffer the negative effects of stress. This study is the first to investigate the moderating role of meaning in life in the relationship between the perception of stress and diurnal cortisol in two independent samples of healthy adults. In study 1 (n = 172, men = 82, women = 90, age range = 21-55 years, mean age = 37.58 years), the results of moderated regression analyses revealed that there was a significant positive relationship between overall perceived stress in the past month and both diurnal cortisol levels (area-under-the-curve with respect to the ground; AUCg) and the diurnal cortisol slope (DCS) only in individuals with low levels of meaning in life conceptualized as the degree to which one engages in activities that are personally valued and important. In study 2 (n = 259, men = 125, women = 134, age range = 18-54 years, mean age = 29.06 years), we found a non-significant interaction term between meaning in life conceptualized as having goals and a sense of excitement regarding one's future and perception of stress in a model of both adjusted AUCg and DCS. The results were independent of age, sex, body mass index, education, and race. The results shed light on the importance and the complexity of the construct of meaning in life and offer a possible explanation for why some people who face stressors may be more vulnerable than others to developing stress-related health problems.

The purpose of this study was to determine the moderating role of psychological stress on exercise-induced immune changes. Twenty-nine recreational runners were recruited for this study four weeks before completing a marathon. Each subject reported: weekly training volume (miles/wk) for the week prior to the study visit; completed the Perceived Stress Scale (PSS), the state version of the State-Trait Anxiety Inventory (STAI) and the Penn State Worry Questionnaire (PSWQ); and donated blood for assessment of CD4+ T cell subpopulations and mitogen-induced cytokine production. Participants ran an average of 30 (±13.4) miles (1 mile=1.6 km) per week. Average values (SD) for immune biomarkers were: regulatory T cells (Treg), 3.2% (±1.2%); type 1 regulatory cells (Tr1), 27.1% (±8.3%); T helper 3 (Th3), 1.8% (±0.7%); interferon gamma (IFNγ), 3.1 pg/ml (±1.0); interleukin (IL)-4, 1.4 pg/ml (±1.1); IFNγ/IL-4, 8.6 (±1.2); IL-10, 512 pg/ml (±288). There was a significant relationship between running volume and both Treg cell numbers (slope of the regression line (β)=0.05, p less than 0.001) and IL-10 production β=-10.6, p=0.002), and there was a trending relationship between running volume and Tr1 cell numbers (β=-0.2%, p=0.064). Perceived stress was a trending moderator of the running volume-Treg relationship, whereas worry was a significant moderator of the running volume-IFNγ and running volume-IFNγ/IL-4 relationships. These data indicate that various forms of psychological stress can impact endurance exercise-based changes in certain immune biomarkers. These changes may reflect an increased susceptibility to clinical risks in some individuals.

    Full Text Available Research on the role of social support in occupational samples has suggested that work-based social support [WBSS] may have a significant buffering and main effect on occupational stress. Using occupational stress research as a model, the present research explored the relationship between WBSS and job-induced post-traumatic stress [PTS] in a sample of cash-in-transit security guards that had experienced a high incidence of armed robberies in the line of duty. Results indicate that WBSS has a significant relationship with PTS. Factors associated with elevated PTS levels are discussed and comparisons are made with guards who had not experienced traumatic incidents.

    Full Text Available Objective: Job stress and burnout levels of oncology nurses increase day-by-day in connection with rapidly increasing cancer cases worldwide as well as in Turkey. The purpose of this study was to establish job stress and burnout levels of oncology nurses and the relationship in between. Methods: The sample of this descriptive study comprised of 189 nurses that are selected by nonprobability sampling method, employed by 11 hospitals in Istanbul. Survey form of 20 questions, Job Stressors Scale and Maslach Burnout Inventory (MBI were used during collection of data. Data were evaluated using percentage, Kruskal-Wallis, Mann-Whitney U and Spearman correlation analyses. Results: In the study, there was a positively weak correlation between "Work Role Ambiguity" subdimension of Job Stressors Scale and "Emotional Exhaustion" and "Personal Accomplishment" subdimensions, whereas a positively weak and medium correlation was encountered between "Work Role Conflict" subdimension and "Emotional Exhaustion" and "Depersonalization" subdimensions. A negatively weak correlation was found between "Work Role Overload" subdimension and "Emotional Exhaustion" and "Depersonalization" subdimensions. Conclusion: A significant relationship was established between subdimensions of job stress level and of burnout level, that a lot of oncology nurses who have participated in the study wanted to change their units, because of the high attrition rate.

    When people who are married or cohabiting face stressful life situations, their ability to cope may be associated with two separate dimensions of interpersonal behavior: positive and negative. These behaviors can be assessed with the Couple Resilience Inventory (CRI). It was expected that scales on this instrument would correlate with outcome variables regarding life well-being, stress, and relationship satisfaction. It was also expected that effects for negative behavior would be larger than effects for positive and that the effects might be curvilinear. Study 1 included 325 married or cohabiting people currently experiencing nonmedical major life stressors and Study 2 included 154 married or cohabiting people with current, serious medical conditions. All participants completed an online questionnaire including the CRI along with an alternate measure of couple behavior (to confirm scale validity), a measure of general coping style (to serve as a covariate), and measures of outcome variables regarding well-being, quality of life, perceived stress, and relationship satisfaction. The effects for negative behavior were larger than effects for positive in predicting most outcomes, and many effects were curvilinear. Notably, results remained significant after controlling for general coping style, and scales measuring positive and negative behavior demonstrated comparable levels of validity.

    Full Text Available Child abuse is behavior in which child faces physical, sexual, negligence and emotional abuses. This study’s aimed to investigate relationship between childhood abuse and self-compassion with stress-coping strategies among women. Statistical population included all of married women in Tehran. The sample contains 182 participants who were selected by convenience sampling method entertainment centers, shopping centers, health centers and cultural centers. The data were collected by Mohammad Khani’s self-report questionnaire, Neff's self-compassion scale and coping strategies of Blings and Mous. The findings showed that emotional abuse with mean of 23.54 was the hisgest and physical abuse with mean of 7.87 was the lowest one. Results showed that there is negative relationship between the abuse’s total score and self-compassion’s total score. All physical abuse's subscales, emotional abuse and negligence can predict the self-compassion except sexual abuse. Also none of the abuse subscales can predict the stress-coping methods. The results have shown that the experience of abuse in childhood injury ,can be affected him in adulthood on self-concept and coping responces to stress and problems.

    Full Text Available Increased aflatoxin contamination in corn by the fungus Aspergillus flavus is associated with frequent periods of drought and heat stress during the reproductive stages of the plants. The objective of this study was to evaluate the relationship between aflatoxin contamination and physiological responses of corn plants under drought and heat stress. The study was conducted in Stoneville, MS, USA under irrigated and non-irrigated conditions. Five commercial hybrids, P31G70, P33F87, P32B34, P31B13 and DKC63-42 and two inbred germplasm lines, PI 639055 and PI 489361, were evaluated. The plants were inoculated with Aspergillus flavus (K-54 at mid-silk stage, and aflatoxin contamination was determined on the kernels at harvest. Several physiological measurements which are indicators of stress response were determined. The results suggested that PI 639055, PI 489361 and hybrid DKC63-42 were more sensitive to drought and high temperature stress in the non-irrigated plots and P31G70 was the most tolerant among all the genotypes. Aflatoxin contamination was the highest in DKC63-42 and PI 489361 but significantly lower in P31G70. However, PI 639055, which is an aflatoxin resistant germplasm, had the lowest aflatoxin contamination, even though it was one of the most stressed genotypes. Possible reasons for these differences are discussed. These results suggested that the physiological responses were associated with the level of aflatoxin contamination in all the genotypes, except PI 639055. These and other physiological responses related to stress may help examine differences among corn genotypes in aflatoxin contamination.

    We investigated whether stress may influence fatigue, or vice versa, as well as factors mediating this relationship. Fifty healthy participants (31 females, 23.6±3.2 years) completed up to 5 momentary assessments of stress and fatigue during 5 days of preparation for their final examinations (exam condition) and 5 days of a regular semester week (control condition). Sleep quality was measured by self-report at awakening. A sub-group of participants (n=25) also collected saliva samples. Fatigue was associated with concurrent stress, stress reported at the previous measurement point, and previous-day stress. However, momentary stress was also predicted by concurrent fatigue, fatigue at the previous time point, and previous-day fatigue. Sleep quality mediated the association between stress and next-day fatigue. Cortisol and alpha-amylase did not mediate the stress-fatigue relationship. In conclusion, there is a reciprocal stress-fatigue relationship. Both prevention and intervention programs should comprehensively cover how stress and fatigue might influence one another.

    Duffy, Stephen [Cleveland State Univ., Cleveland, OH (United States)

    2013-09-09

    This project will implement inelastic constitutive models that will yield the requisite stress-strain information necessary for graphite component design. Accurate knowledge of stress states (both elastic and inelastic) is required to assess how close a nuclear core component is to failure. Strain states are needed to assess deformations in order to ascertain serviceability issues relating to failure, e.g., whether too much shrinkage has taken place for the core to function properly. Failure probabilities, as opposed to safety factors, are required in order to capture the bariability in failure strength in tensile regimes. The current stress state is used to predict the probability of failure. Stochastic failure models will be developed that can accommodate possible material anisotropy. This work will also model material damage (i.e., degradation of mechanical properties) due to radiation exposure. The team will design tools for components fabricated from nuclear graphite. These tools must readily interact with finite element software--in particular, COMSOL, the software algorithm currently being utilized by the Idaho National Laboratory. For the eleastic response of graphite, the team will adopt anisotropic stress-strain relationships available in COMSO. Data from the literature will be utilized to characterize the appropriate elastic material constants.

    This study examined the relationships among dissociation, childhood trauma and sexual abuse, and posttraumatic stress disorder (PTSD) symptoms in HIV-positive men. Data was collected from 167 men enrolled in a randomized clinical trial (Project RISE) that examined a group therapy intervention to decrease HIV-related risk behavior and trauma-related stress symptoms. Participants completed the Trauma History Questionnaire, the Impact of Event Scale - Revised, and the Stanford Acute Stress Reaction Questionnaire. Overall, 35.3% of the participants reported having experienced childhood sexual abuse (CSA). A total of 55.7% of the sample met diagnostic criteria for PTSD. The intensity of dissociative symptoms that participants endorsed was positively associated with experience of childhood sexual abuse (r = .20, p Dissociative symptoms were also positively associated with specific PTSD symptoms, notably hyperarousal (r = .69, p dissociation than childhood sexual abuse. These results suggest that childhood sexual abuse may be involved in the development of dissociative symptoms in the context of adulthood stress reactions. Furthermore, the pattern of the association between dissociation and PTSD is consistent with the possibility of a dissociative PTSD subtype among HIV-positive men. PMID:22211444

    The menstrual cycle involves significant changes in hormone levels, causing physical and psychological changes in women that are further influenced by stress. The aim of this study was to understand the relationship between menstrual cycle phase and salivary cortisol patterns during the day as well as the salivary cortisol response to the Virtual Reality Version of the Trier Social Stress Test (TSST-VR). Forty two women not taking oral contraceptives (24 in follicular phase and 18 in luteal phase) participated in the study. Five samples of salivary cortisol collected during the day and another five samples of cortisol during the TSST-VR were analyzed. Psychological stress measures and psychopathological symptomatology were also evaluated. A 2 × 4 mixed ANCOVA showed an interaction between the two groups on the TSST-RV invoked cortisol response to the [F(3,42) = 3.681; p = 0.023) where women in luteal phase showed higher cortisol post exposure levels (5.96 ± 3.76 nmol/L) than women in follicular phase (4.31 ± 2.23 nmol/L). No other significant differences were found. Our findings provide evidence that menstrual cycle phase tended to influence cortisol response to laboratory-induced mental stress, with more reactivity observed in the luteal phase.

    Endocrine changes due to menopause have been associated to oxidative stress and muscle mass loss. The study objective was to determine the relationship between both variables in early postmenopause. An exploratory, cross-sectional study was conducted in 107 pre- and postmenopausal women (aged 40-57 years). Levels of serum lipid peroxides and uric acid and enzymes superoxide dismutase and glutathione peroxidase, as well as total plasma antioxidant capacity were measured as oxidative stress markers. Muscle mass using bioelectrical impedance and muscle strength using dynamometry were also measured. Muscle mass, skeletal muscle index, fat-free mass, and body mass index were calculated. More than 90% of participants were diagnosed with overweight or obesity. Postmenopausal women had lower values of muscle mass and strength markers, with a negative correlation between lipid peroxide level and skeletal muscle index (r= -0.326, p<.05), and a positive correlation between uric acid and skeletal muscle index (r=0.295, p<.05). A multivariate model including oxidative stress markers, age, and waist circumference showed lipid peroxide level to be the main contributor to explain the decrease in skeletal muscle mass in postmenopause, since for every 0.1μmol/l increase in lipid peroxide level, skeletal muscle index decreases by 3.03 units. Our findings suggest an association between increased oxidative stress and muscle mass loss in early postmenopause. Copyright © 2018 SEEN y SED. Publicado por Elsevier España, S.L.U.

    Full Text Available This paper is a theoretical review whose general objective was to analyze the complex links between two frequently recurring phenomena in the field of mental health: the stress and depression, from the psychoneuroendocrinological point of view, considering the implication of the cortisol hormone on the relationship mentioned above. For this purpose we proceeded through a database search in Medline, Pubmed, Wiley Online Library, and Scielo data. It was concluded that chronic stress and some forms of depression would establish a continuum. They have neurobiological and pathophysiological basis with many similarities. In addition, a hostile environment during early childhood would increase the vulnerability to the stress and to suffering from depression in the adulthood. The epigenetic studies indicated the methylation of glucocorticoid receptor gene as mechanism associated with the development of this vulnerability. Finally, so much the psychotherapy cognitive behavioral as the administration of antidepressing medication, they have demonstrated to reach his therapeutic effects across the increase in neural plasticity on cerebral key structures in the neurobiological processes involved in the stress.

    Men with prostate cancer often need social support to help them cope with illness-related physiological and psychosocial challenges. Whether those needs are met depends on receiving support optimally matched to their needs. This study examined relationships between perceived stress, prostate cancer-related stigma, weak-tie support preference, and online community use for social support in a survey of online prostate cancer community participants (n = 149). Findings revealed a positive relationship between stigma and perceived stress. This relationship, however, was moderated by weak-tie support preference and online community use for social support. Specifically, stigma was positively related to perceived stress when weak-tie support was preferred. Analyses also showed a positive relationship between stigma and perceived stress in those who used their online community for advice or emotional support. Health communication scholars should work collaboratively with diagnosed men, clinicians, and online community administrators to develop online interventions that optimally match social support needs.

    The disposal of low-level nuclear wastes by burial in deep sea sediments is an option currently being considered. This report lays the groundwork for an investigation of the stability of canisters containing nuclear wastes against movement due to fluidisation of the surrounding sediments, where such fluidisation may result from thermally induced stresses. The requisite constitutive relationships for ocean sediments under stress and temperature gradients are derived from the theory of critical state soil mechanics. A parametric survey has been made of the behaviour of an element of soil in order to assess various models and the importance of the governing parameters, The formulation of a finite element algorithm is given for the solution of the sediment stability problem.

    Four and seven weeks after powerful earthquakes in El Salvador, the authors examined the relationships among demographics, traumatic event exposure, social support, resource loss, acute stress disorder (ASD) symptoms, depression, and posttraumatic growth. Participants were 253 college students (Study 1) and 83 people in the community (Study 2). In Study 1, female gender, traumatic event exposure, low social support, and loss of personal characteristic, condition, and energy resources contributed to ASD symptoms and depression. In Study 2, damage to home and loss of personal characteristic and object resources contributed to ASD symptoms and depression. Posttraumatic growth was not associated with ASD symptoms or depression. Findings support the conservation of resources stress theory (Hobfoll, 1998). Resource loss spirals, excessive demands on coping, and exposure to multiple disasters are discussed.

    Research purpose: The main objective of this study was to assess the relationship between indicators of wellbeing and stress and to further assess the relative importance of these wellbeing indicators in explaining stress variance in a large sample of Eastern Cape primary and high school teachers in South Africa. Motivation for the study: The majority of teacher stress studies focus on the misfit between the individual’s resources and the environmental demands. There is a scarcity of studies reporting on protective factors in teaching and we know little about their possible role as possible protective factors against stress. This is important in developing stress prevention strategies. Research design, approach and method: A cross-sectional survey was used targeting public school teachers in the Eastern Cape. The sample size was 562 randomly selected teachers from both public primary and high schools. Main findings: The results revealed that stress is prevalent amongst teachers. Subjective and psychological wellbeing factors added significantly to the explained stress variance. Also, both negative affect and role problems had significant positive correlations with stress, whilst psychological wellbeing had a strong inverse relationship with stress. Practical/managerial implications: The results implied that interventions focusing on improving psychological wellbeing and reduction of negative affect can contribute to stress prevention. Contribution/value-add: The results contributed towards a better understanding of the relative importance of wellbeing constructs as protective factors against teacher stress.

    The role of psychosocial stress in the development of obesity and metabolic syndrome is receiving increased attention and has led to examination of whether physical activity may moderate the stress-metabolic syndrome relationship. The current study examined relationships among physical activity, stress, and metabolic syndrome in adolescents. Participants (N = 126; 57 girls, 69 boys) were assessed for anthropometry, psychosocial stress, physical activity, and metabolic syndrome variables; t tests were used to examine sex differences, and regression analysis was used to assess relationships among variables controlling for sex and maturity status. Mean body mass index approached the 75th percentile for both sexes. Typical sex differences were observed for systolic blood pressure, time spent in moderate and vigorous physical activity, and perceived stress. Although stress was not associated with MetS (β = -.001, P = .82), a modest, positive relationship was observed with BMI (β = .20, P = .04). Strong relationships between physical activity and stress with MetS or BMI were not found in this sample. Results may be partially explained by overall good physical health status of the participants. Additional research in groups exhibiting varying degrees of health is needed.

    2015-12-01

    Although lesbian women are more likely to be obese compared to heterosexual women, relatively little research has examined correlates of overweight and obesity among lesbians. The purpose of this study was to examine the association of minority stress and depression, relationship quality, and alcohol-use variables to overweight and obesity among lesbians in relationships. Self-identified lesbians (n=737) in current relationships completed measures of demographics, minority stress, depressive symptoms, relationship variables, and alcohol use. Overweight and obesity were associated with more public identification as a lesbian, more depressive symptoms, increased heavy drinking, longer relationship length, and lower relationship consensus. Health promotion and weight loss intervention programs for lesbians should incorporate psychological, relationship, and alcohol use components to reduce overweight and obesity among lesbians.

    The present study examined whether individuals' personality traits, Neuroticism and Conscientiousness, moderated the relationship between perceived stress and depressive symptoms among U.S. Chinese older adults. Data analysis was based on the Population Study of Chinese Elderly in Chicago (PINE). Three thousand one hundred and fifty-nine Chinese adults aged 60 years and older participated in the PINE study. They completed scales that assessed their personality (ie, Neuroticism and Conscientiousness of the NEO Five-Factor Inventory), perceived stress (the Chinese Perceived Stress Scale), and depressive symptoms (the Patient Health Questionnaire). Perceived stress was positively related to depressive symptoms among U.S. Chinese older adults. No moderation effects were found for Neuroticism. Conscientiousness significantly moderated the perceived stress-depressive symptom relationship. The positive relationship between perceived stress and depressive symptoms was weaker for people who were higher in Conscientiousness than those who were lower in Conscientiousness. Conscientiousness mitigated the stress-depressive symptom relationship among U.S. Chinese older adults. Future research is needed to identify the psychological and sociocultural profiles of individuals who show stress resilience and those who are vulnerable. Social services and psychological interventions are needed to promote health and well-being among U.S. Chinese older adults. © The Author 2017.

    2017-06-01

    This study examined whether daily variations in levels of mothers' work, home, and relationship stress were related to collaborative and oppositional qualities of mother-child conflict interactions across 1 week. Mothers reported on 1 specific conflict interaction with their 5- to 8-year-old child and their work, home, and relationship stress through online surveys each day for 7 consecutive days. Diary data from 142 mothers were analyzed in 6 multilevel models, each including within- and between-family levels of a stressor predicting collaborative or oppositional conflict qualities. Results suggested that families in the sample differed from each other, and also varied during the week, in collaborative and oppositional conflict qualities as well as stress in all 3 domains. Mothers reported a greater degree of oppositional conflict qualities on days characterized by higher perceptions of home chaos. Additionally, mothers who reported higher average levels of negativity in romantic relationships endorsed oppositional conflict qualities to a greater extent than mothers with lower relationship negativity. Two multilevel models including all 3 stressors in relation to collaborative and oppositional conflict revealed that for mothers managing multiple roles, average romantic relationship stress was the most important unique contributor to mother-child conflict qualities and daily relationship stress was particularly influential among mothers with sons compared to those with daughters. Results support the spillover hypothesis of stress within the family system and are discussed in terms of mothers' coping mechanisms and emotional engagement.

    2010-01-01

    This study examined associations between intimate partner aggression and physical health symptoms among a sample of help-seeking women experiencing relationship aggression (N = 388). Using a structural equation modeling framework, the authors found posttraumatic stress disorder (PTSD) symptoms to fully mediate the associations of both physical and psychological aggression with physical health symptoms. The influence of PTSD symptoms on physical health symptoms was partially mediated by anger/irritability. Results were consistent with studies from other trauma groups suggesting that PTSD is pivotal with respect to explaining the effects of trauma on health. PMID:17874920

  5. Linear and non-linear dose-response functions reveal a hormetic relationship between stress and learning.

    Zoladz, Phillip R; Diamond, David M

    2008-10-16

    Over a century of behavioral research has shown that stress can enhance or impair learning and memory. In the present review, we have explored the complex effects of stress on cognition and propose that they are characterized by linear and non-linear dose-response functions, which together reveal a hormetic relationship between stress and learning. We suggest that stress initially enhances hippocampal function, resulting from amygdala-induced excitation of hippocampal synaptic plasticity, as well as the excitatory effects of several neuromodulators, including corticosteroids, norepinephrine, corticotropin-releasing hormone, acetylcholine and dopamine. We propose that this rapid activation of the amygdala-hippocampus brain memory system results in a linear dose-response relation between emotional strength and memory formation. More prolonged stress, however, leads to an inhibition of hippocampal function, which can be attributed to compensatory cellular responses that protect hippocampal neurons from excitotoxicity. This inhibition of hippocampal functioning in response to prolonged stress is potentially relevant to the well-described curvilinear dose-response relationship between arousal and memory. Our emphasis on the temporal features of stress-brain interactions addresses how stress can activate, as well as impair, hippocampal functioning to produce a hormetic relationship between stress and learning.

  6. The role of stress in the relationships between gender and health-promoting behaviours.

    2010-09-01

    Studies have shown that in Western societies, women live longer than men. Among other factors, this has been attributed to health behaviours; men engage in health-risking behaviours, while women perform health-promoting behaviours. These tendencies were argued to align with cultural notions of masculinity and femininity. There may be some evidence, however, that men and women engage in different types of health-promoting behaviours, and stress may play a role in these tendencies. This study attempts to examine the various types of health-promoting behaviours women engage in and compare them to the tendencies of men. Secondly, it examines the mediating role of stress in the relationships between gender and health-promoting behaviours. The sample was comprised of 402 young Israeli adults. Half were undergraduate university students majoring in social work. The remaining participants were sampled by 'snowball sampling'. Participants completed a questionnaire containing 63 closed-ended questions on various health issues. For the purpose of this study, gender, stress and health-promoting behaviours measures were used. Data were collected over three academic years by the teacher responsible for the course and were received by the author at the end of the data collection phase. The study was approved by the institution's internal review board. The results indicate that,-while women engage in 'type 2 behaviours'- refraining from smoking and drinking, eating breakfast regularly and sleeping 7-8 hours per night-men engage in 'type 1 behaviours'- physical exercise, refraining from snacking, and maintaining an appropriate body mass. We also found that, to some extent, women refrain from 'type 1 behaviours' because of their levels of general stress. Our study suggests that the social construction of masculinity and femininity which undermines individuals' health needs to be challenged and addressed. In particular, the enduring role of stress in women's health outcomes should be

    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

    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.

  9. Identification of stress responsive genes by studying specific relationships between mRNA and protein abundance.

    Protein expression is regulated by the production and degradation of mRNAs and proteins but the specifics of their relationship are controversial. Although technological advances have enabled genome-wide and time-series surveys of mRNA and protein abundance, recent studies have shown paradoxical results, with most statistical analyses being limited to linear correlation, or analysis of variance applied separately to mRNA and protein datasets. Here, using recently analyzed genome-wide time-series data, we have developed a statistical analysis framework for identifying which types of genes or biological gene groups have significant correlation between mRNA and protein abundance after accounting for potential time delays. Our framework stratifies all genes in terms of the extent of time delay, conducts gene clustering in each stratum, and performs a non-parametric statistical test of the correlation between mRNA and protein abundance in a gene cluster. Consequently, we revealed stronger correlations than previously reported between mRNA and protein abundance in two metabolic pathways. Moreover, we identified a pair of stress responsive genes ( ADC17 and KIN1 ) that showed a highly similar time series of mRNA and protein abundance. Furthermore, we confirmed robustness of the analysis framework by applying it to another genome-wide time-series data and identifying a cytoskeleton-related gene cluster (keratin 18, keratin 17, and mitotic spindle positioning) that shows similar correlation. The significant correlation and highly similar changes of mRNA and protein abundance suggests a concerted role of these genes in cellular stress response, which we consider provides an answer to the question of the specific relationships between mRNA and protein in a cell. In addition, our framework for studying the relationship between mRNAs and proteins in a cell will provide a basis for studying specific relationships between mRNA and protein abundance after accounting for potential

    Nursing education can be a stressful experience. To fully benefit from this experience and develop a positive professional identity, it is essential for nursing students to effectively cope with education-related stress. The aim of the study was to investigate the relationships between nursing students' education-related stress and stress coping, self-esteem, social support, and health status. This study utilized a cross-sectional, descriptive, and correlational design. The sample consisted 517 nursing students from a bachelor program in Turkey during the 2014-2015 academic year. Participants provided data on sociodemographic characteristics as well as completing the following instruments: Nursing Education Stress Scale, Coping Behavior Inventory for Nursing Students, Multidimensional Scale of Perceived Social Support, Rosenberg Self-Esteem Scale, and General Health Questionnaire. Relationships were examined using multivariate structural equation modeling. Results indicated that nursing students' stress coping levels were affected by self-esteem and social support. Additionally, this interaction appears to affect general health status. Although the direct effect of stress on coping was non-significant, its overall effect was significant within the model. It is necessary to conduct further intervention studies examining the role of self-esteem and social support in facilitating nursing students' stress-related coping during their education.

    Negative perceptions of self and others have lately become one of the criteria for Posttraumatic Stress Disorder (PTSD) among adults and adolescents. Drawing from theories of mental representations in psychopathology, this study examined self-reported negative cognitions, self and parental representations, and relationship themes among adolescents with and without PTSD. Thirty one adolescents with PTSD (11 boys, mean age = 14.06, SD = 2.24) were matched with 29 adolescents who had no psychiatric diagnosis (11 boys, mean age = 14.96, SD = 1.78). Adolescents completed self-report measures, wrote a description of self, mother and father, and were interviewed about positive and negative relationship episodes with mother, father, and peers. Adolescents with PTSD reported more self-criticism and performance evaluation than did controls. Their self-representation exhibited a lower sense of agency, which was related to structural variables (i.e., less integrative description). Although parental representations of adolescents with PTSD were not generally less benevolent or more punitive than those of controls, their relationship themes revealed a higher proportion of the wish to be distant from others. Adolescents with PTSD exhibited more passive responses and perceived more dominant or controlling responses from their parents. Findings point out to a serious impairment in representations of self and relationship patterns in adolescent PTSD.

    Sexual minorities are exposed to stressors in the workplace (workplace minority stress), which can be detrimental for well-being (e.g., levels of anxiety). The present study examined whether a particular set of relationship processes, dyadic coping, served to moderate the association between workplace minority stress and symptoms of anxiety. Using a dyadic sample of 64 female same-sex couples, we found that partner problem-focused supportive dyadic coping (DC) and emotion-focused supportive DC (marginally) buffered, whereas partner delegated DC and negative DC did not moderate, the association between workplace minority stress and symptoms of anxiety. Implications for relationship researchers and mental health practitioners are discussed.

    Recently, workers' mental health has become important focus in the field of occupational health management. Depression is a psychiatric illness with a high prevalence. The association between job stress and depressive symptoms has been demonstrated in many studies. Recently, studies about the association between sleep quality and depressive symptoms have been reported, but there has been no large-scaled study in Korean female workers. Therefore, this study was designed to investigate the relationship between job stress and sleep quality, and depressive symptoms in female workers. From Mar 2011 to Aug 2011, 4,833 female workers in the manufacturing, finance, and service fields at 16 workplaces in Yeungnam province participated in this study, conducted in combination with a worksite-based health checkup initiated by the National Health Insurance Service (NHIS). In this study, a questionnaire survey was carried out using the Korean Occupational Stress Scale-Short Form(KOSS-SF), Pittsburgh Sleep Quality Index(PSQI) and Center for Epidemiological Studies-Depression Scale(CES-D). The collected data was entered in the system and analyzed using the PASW (version 18.0) program. A correlation analysis, cross analysis, multivariate logistic regression analysis, and hierarchical multiple regression analysis were conducted. Among the 4,883 subjects, 978 subjects (20.0%) were in the depression group. Job stress(OR=3.58, 95% CI=3.06-4.21) and sleep quality(OR=3.81, 95% CI=3.18-4.56) were strongly associated with depressive symptoms. Hierarchical multiple regression analysis revealed that job stress displayed explanatory powers of 15.6% on depression while sleep quality displayed explanatory powers of 16.2%, showing that job stress and sleep quality had a closer relationship with depressive symptoms, compared to the other factors. The multivariate logistic regression analysis yielded odds ratios between the 7 subscales of job stress and depressive symptoms in the range of 1

    Job stress is a serious threat to the quality of working life (QWL) of health-care employees and can cause hostility, aggression, absenteeism and turnover, as well as reduced productivity. In addition, job stress among employees affects the quality of health-care services. The purpose of this study was to gain a better understanding of the relationships between job stress and QWL of employees, and their impact on turnover intention at Isfahan hospitals, Iran. The study employed a cross-sectional research design. A validated questionnaire was used to collect data from hospital employees. Overall, 26% of employees graded their job stress high. The major sources of stress were inadequate pay, inequality at work, too much work, staff shortage, lack of recognition and promotion prospects, time pressure, lack of job security and lack of management support. An inverse relationship was found between job stress and QWL among hospital employees. The most important predictor of QWL was disturbance handling, followed by job proud, job security and job stress. Finally, while QWL was negatively associated with turnover intentions, job stress was positively related to employees' intention to quit. Since job stress has a strong correlation with employee QWL and turnover intention, it is very important to apply the right human resources policies to increase employees' QWL and decrease subsequent turnover. This study invites further research to explore, implement and evaluate intervention strategies for prevention of occupational stress and improvement in QWL.

    Scientific Abstract Adults with autism spectrum disorder (ASD) face substantial challenges accomplishing basic tasks associated with daily living, which are exacerbated by their broad and pervasive difficulties with social interactions. These challenges put people with ASD at increased risk for psychophysiological distress, which likely factors heavily into social functioning for adults with ASD, as suggested by a growing literature on stress in children that indicates that children with ASD have differential responses to stress than healthy children. We hypothesized that adults with ASD and without intellectual disability (n=38) would experience more stress than healthy volunteers (n=37) and that there would be an inverse relationship between stress and social functioning in individuals with ASD. Baseline, semi-structured interview data from a randomized-controlled trial of two treatments for adults with ASD were used to assess differences in stress between adults with ASD and healthy volunteers and to assess the relationship between stress response and social functioning in adults with ASD. Findings indicate that adults with ASD experience greater perceived and interviewer-observed stress than did healthy volunteers and that stress is significantly related to social functioning in adults with ASD. These findings highlight the role of stress in adult functioning and outcomes and suggest the need to develop and assess treatments designed to target stress and coping in adults with ASD.

    Full Text Available Background: Several behavioral factors, specially stress, eating behavior, and physical activity have been linked with adolescent obesity. In our country, mental health of adolescents is often neglected. So, we designed this study to describe the current perception of stress in Bangladeshi adolescent students. Objective: Aim of this study was to assess association between stress and body mass index of adolescents while controlling for physical activity and examining stress associated eating behavior. Materials and Methods: This cross-sectional study was carried out among 278 adolescent students during the period from January to December 2013. Data were collected through self-administered questionnaire which included physical activity questions, Dutch Eating Behavior Questionnaire (DEBQ, Adolescent stress questionnaire (ASQ and standard anthropometric measurements and were analyzed statistically using SPSS version 21.0. Results: In this study majority of the respondents were males. Among the female respondents, about 12.23% were overweight and obese compared to their male peers (4.1%. The normal and high BMI adolescents in the study showed significantly different proportions regarding gender (p<0.001, father’s education (p=0.036 and smoking status (p=0.22.

    Full Text Available In the paper we present a measure assessing and distinguishing between shame-proneness and guilt-proneness, TOSCA-3 (Test of Self-Conscious Affect; Tangney & Dearing, 2002, and describe its theoretical and research background. Shame is defined as a non-functional and deeply concealed emotion, involving feelings of exposure and unworthiness, which focuses on the self and potentially leads to social isolation. In contrast, guilt is described as a less painful and more functional emotion, focusing on behavior and motivating interpersonal reparation. We also present a study with a sample of students on the relationship of shame and guilt to stress, anxiety and depression. The study confirmed the results obtained with other tests, showing that shame-proneness as opposed to guilt-proneness is moderately linked to anxiety and depression. The study also demonstrated the relationship of shame-proneness to stress. In the conclusion, the possibilities of further research on interpersonal implications of shame-proneness and with specific populations are discussed.

    Occupational stress can have a harmful effect on the individual both physically and psychologically. In Korea, occupational stress of physician is rarely demonstrated. Although it is well reported that physicians tend to have a high incidence of minor psychiatric disorders, the magnitude of the problem remains unclear. Interns and residents are thought to be under substantial amount of stress, and tend to have psychiatric disorder. In this paper, we aimed to evaluate the relationship between the occupational stress and depression of residents. The participants of this study were surgical and medical residents in a tertiary hospital in Korea. For measurement of occupational stress, we used an occupational stress scale. In addition, to evaluate the prevalence of depression, we used the Beck Depression Inventory. Female doctors showed higher degree of occupational stress than the males. The interns and chief residents showed higher degree of occupational stress than the other residents. Interestingly, in this study, most of the participants experienced a depressive mood. Compared with the general population, job demand and culture of workplace were high. Occupational stress was the only significant predictor of a depressive mood. Hospital residents experience a high degree of occupational stress leading to a depressed mood due to various risk factors. Therefore, it is essential to recognize the occupational stress of residents early, to encourage positive competition and peer and social support, and to help improve the residents' ability to cope with stress.

The technique utilized ultrasonic pulse-echo that determined the wave velocity change due to torque applied between bolt and nut. Mild steel bar with nominal diameter of 19 and 25mm were used. The specimen was loaded by means of a torque wrench that gave the required amount of moment (∼300Nm). This was carefully achieved manually. In order to measure the strain, strain gauges were employed. The direct strain gauge method gives the strain values. This strain is used to calculate the stress due to the applied load. The experiment had been carried out in a control environment with constant temperature. The relationship between torque-velocity, torque-strain and stress-strain is obtained and compared. The test results indicate that ultrasonic wave velocity decrease with the applied torque. This is due to degradation or loss of strength of the material. The potential of this NDT method to obtain structure quality and strength determination is discussed. (author)

    It has been suggested that oxidative stress may have a role in the etiopathogenesis of congestive heart failure. To investigate and compare the oxidative-antioxidative status and oxidative stress index (OSI) of patients with idiopathic dilated cardiomyopathy (IDC) with those of healthy volunteers, and to determine the relationship between total antioxidant capacity (TAC) and ejection fraction (EF). Twenty-eight patients with IDC and 24 control subjects were enrolled in the study. Antioxidative status was evaluated by measuring the TAC and the vitamin C and thiol levels in the plasma. Oxidative status was evaluated by measuring the total peroxide level. The per cent ratio of TAC to total peroxide level was accepted as the OSI. EF was measured using Simpson's method. TAC and vitamin C and thiol levels of plasma were found to be significantly lower in patients with IDC than in control subjects (P total peroxide levels and OSIs were significantly higher in patients with IDC than in control subjects (P = 0.002 and P = 0.002, respectively). An important positive correlation was found between TAC and EF (r = 0.772; P total peroxide levels in patients. Oxidants are increased and antioxidants are decreased in patients with IDC; as a result, the oxidative-antioxidative balance is shifted to the oxidative side. There is a significant correlation between the potency of oxidative stress and the severity of IDC. It is believed that supplementation of antioxidants in the treatment of IDC may be helpful to these patients.

    Pregnancy is a period involving important metabolic changes that enable the maintenance of the mother's health and development of the fetus. This study aimed to assess the relationship among periodontal disease, insulin resistance, salivary cortisol concentration and level of perceived stress in pregnant women. This was a cross-sectional study. The sample comprised 96 pregnant women between the fifth and seventh month of pregnancy registered at the Basic Health Units of the Unified Health System (SUS). The periodontal condition was assessed after obtainment free and informed consent from the participants. Participants were divided into three groups: control subjects with a healthy periodontal condition (CN; n=46), patients with gingivitis (GI; n=26), and patients with periodontitis (PI; n=24). Saliva and blood samples were collected for evaluation of salivary cortisol concentration, glycemia, insulinemia and Homeostasis Model Assessment-Insulin Resistance index. A validated survey for the assessment of perceived stress levels was also performed. PI group showed significantly higher (pperiodontal disease during pregnancy. This study emphasizes the importance of preventing periodontitis in order to avoid insulin resistance and stress during pregnancy since these can cause systemic complications for the mother and the fetus.

    Law enforcement officers suffer higher morbidity and mortality rates from all causes than the general population. Cardiovascular disease (CVD) accounts for a significant portion of the excess illness, with a reported prevalence as high as 1.7 times that of the general population. To determine which occupational hazards cause this increased risk and morbidity, it is imperative to study law enforcement officers before they retire. The long-range goal of our research is to reduce the incidence of CVD-related illness and death among aging law enforcement officers. The purpose of the present study was to measure pro- and anti-atherogenic inflammatory markers in blood samples from law enforcement officers (n = 71) and determine what types of occupation-related stress correlate with differences in these markers. For each outcome variable of interest, we developed separate regression models. Two groups of potential predictors were examined for inclusion in the models. Selected measures of stress were examined for inclusion in the models, in addition to general covariates, such as gender, ethnicity, years in law enforcement, and body mass index. Our results revealed statistically significant relationships between several physiologic variables and measures of stress. PMID:21362637

    The introduction of High-Strength Steel (HSS) reinforcing bars in reinforced concrete members has gained much attention in recent years and led to many advantages such as construction timesaving. It is also more economical since it can reduce the amount of reinforcing steel bars used in concrete members which in turn alleviates the congestion of reinforcement. Up to present, the building codes, e.g. American Concrete Institute (ACI) 318M-14 and Standard National Indonesia (SNI) 2847:2013, still restrict the use of higher-strength steel reinforcing bars for concrete design up to Grade 420 MPa due to the possible suspected brittle behavior of concrete members. This paper evaluates the characteristics of stress-strain relationships of HSS bars if they are comparable to the characteristics of those of Grade 420 MPa. To achieve the objective of the study, a series of steel bars from various grades (420, 550, 650, and 700 MPa) was selected. Tensile tests of these steel samples were conducted under displacement-controlled mode to capture the complete stress-strain curves and particularly the post-yield response of the steel bars. The results indicate that all the steel bars tested had the actual yield strengths greater than the corresponding specified values. The stress-strain curves of HSS reinforcing bars (Grade 550, 650, and 700 MPa) performed slightly different characteristics with those of Grade 420 MPa.

    Neighborhood quality is associated with health. Increasingly, researchers are focusing on the mechanisms underlying that association, including the role of stress, risky health behaviors, and subclinical measures such as allostatic load (AL). This study uses mixed-effects regression modeling to examine the association between two objective measures and one subjective measure of neighborhood quality and AL in an ethnically diverse population-based sample (N = 2706) from a medium-sized Texas city. We also examine whether several measures of psychological stress and health behaviors mediate any relationship between neighborhood quality and AL. In this sample, all three separate measures of neighborhood quality were associated with individual AL (P < .01). However, only the subjective measure, perceived neighborhood quality, was associated with AL after adjusting for covariates. In mixed-effects multiple regression models there was no evidence of mediation by either stress or health behaviors. In this study, only one measure of neighborhood quality was related to a measure of health, which contrasts with considerable previous research in this area. In this sample, neighborhood quality may affect AL through other mechanisms, or there may be other health-affecting factors is this area that share that overshadow local neighborhood variation.

    Comorbid psychopathology and stress were considered possible mediators that may explain the relationship between some autistic traits and repetitive behaviours. The current study sought to examine the mediational effects of comorbid psychopathology, executive dysfunctions and stress in the relationship between some autistic traits and repetitive behaviours. A battery of questionnaires including measures of autistic traits, repetitive behaviours, stress, executive dysfunctions and comorbid psychopathology were administered to a sample of adults with autism and intellectual disabilities (n = 43). We found that when taken as set dimensions of comorbidity, dysexecutive functioning and stress mediated or explained the effects of autistic symptoms on repetitive behaviour. The total model explained 60% of the variation in repetitive behaviours (R = 0.60; F = 13.64, P autism, while executive functioning did not contribute to that relationship. © 2013 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    In this longitudinal study, we examined the relationship between the sources and functions of social support and dimensions of child- and parent-related stress for mothers of young children with mild developmental delays. Sixty-three mothers completed assessments of stress and support at two time points. Multiple regression analyses revealed that parenting support during the early childhood period (i.e. advice on problems specific to their child and assistance with child care responsibilities), irrespective of source, consistently predicted most dimensions of parent stress assessed during the early elementary years and contributed unique variance. General support (i.e. primarily emotional support and validation) from various sources had other, less widespread effects on parental stress. The multidimensional perspective of the construct of social support that emerged suggested mechanisms mediating the relationship between support and stress and provided a framework for intervention.

Zalewska. Workaholism was measured once - before a holiday, the explained and intervening variables (the level of conflicts and stress, respectively) were measured at three stages. To test the mediating role of general and occupational stress, hierarchical regression analysis as well as the method of bootstrapping were applied. Our results indicate that general stress is an important mediator of the relationship between workaholism recognized as an addiction and work-family conflicts. Occupational stress turned out to be the only mediator in the relationship between workaholism (recognized as an addiction) and the work-family conflict, noted exclusively in the first stage of the study. Both general and occupational stress were not significant mediators in the relationship between workaholism recognized as a behavioral tendency and the conflicts described.

    This study sought to clarify the importance and cross-cultural relevance of associations between generalized perceived stress and depression. Also tested was the hypothesis that perceived stress would correlate more strongly with anxiety than with depression, whereas control would be more predictive of depression than of anxiety. Relationships between perceived stress, anxiety, depression, and perceived control were examined in samples of Iranian (n = 191) and American (n = 197) undergraduates. Correlations among these variables were generally similar across the two societies. Perceived stress did predict anxiety better than depression, but perceptions of control predicted depression significantly better than anxiety only in the United States. Best fitting structural equation models revealed that anxiety and perceived control completely accounted for the linkage between perceived stress and depression in both societies. An equally acceptable and more parsimonious model described perceived stress as a consequence rather than as an antecedent of anxiety and perceived control. Structural equation models were essentially identical across the two cultures except that internal control displayed a significant negative relationship with anxiety only in Iran. This result seemed to disconfirm any possible suggestion that a supposedly individualistic process like internal control could have no noteworthy role within a presumably more collectivistic Muslim society like Iran. Overall, these data documented the importance of anxiety and perceived control in explaining the perceived stress-depression relationship cross-culturally and therefore questioned the usefulness of perceived stress in predicting depression. Whether this understanding of the stress-depression relationship deserves general acceptance will require additional studies that measure the frequency of stressful life events and that utilize a longitudinal design.

    Objectives : There is insufficient evidence regarding the potential risk of mobile phone use on mental health. Therefore, the aim of this research was to examine the relationship between mobile phone use and mental health by measuring the levels of depression, anxiety, and stress among university students in Serbia and Italy. Methods : This cross-sectional study was carried out at two distinguished universities in Serbia and Italy from March to May of the 2015/2016 academic year and included 785 students of both genders. The questionnaire was compiled and developed from different published sources regarding the manner and intensity of mobile phone use, along with the Depression Anxiety Stress Scale (DASS 42) for measuring psychological health. The statistical analysis of the data included the application of binary logistic regression and correlation tests. Results: Statistical analysis indicates that anxiety symptoms are somewhat more present in younger students (odds ratio (OR) = 0.86, 95% confidence interval (CI): 0.76-0.96), in those who send more text messages SMSs (OR = 1.15, 95% CI: 1.11-1.31), and in those who browse the internet less frequently (OR = 0.84, 95% CI: 0.73-0.95). Stress is more common in students who make fewer calls a day (OR = 0.79, 95% CI: 0.64-0.97), as well in those who spend more time talking on the mobile phone per day (OR = 1.28, 95% CI: 1.12-1.56). The strongest predictor of high stress levels was keeping the mobile phone less than 1 m away during sleeping (OR = 1.48, 95% CI: 1.12-2.08). Conclusions: The results indicated that the intensity and modality of mobile phone use could be a factor that can influence causal pathways leading to mental health problems in the university student population.

    In horses, hyperinsulinemia and insulin resistance (insulin dysregulation) are associated with the development of laminitis. Although obesity is associated with insulin dysregulation, the mechanism of obesity-associated insulin dysregulation remains to be established. We hypothesized that oxidative stress in skeletal muscle is associated with obesity-associated hyperinsulinemia in horses. Thirty-five light breed horses with body condition scores (BCS) of 3/9 to 9/9 were studied, including 7 obese, normoinsulinemic (BCS ≥ 7, resting serum insulin obese, hyperinsulinemic (resting serum insulin ≥ 30 μIU/mL) horses. Markers of oxidative stress (oxidative damage, mitochondrial function, and antioxidant capacity) were evaluated in skeletal muscle biopsies. A Spearman's rank correlation coefficient was used to determine relationships between markers of oxidative stress and BCS. Furthermore, to assess the role of oxidative stress in obesity-related hyperinsulinemia, markers of antioxidant capacity and oxidative damage were compared among lean, normoinsulinemic (L-NI); obese, normoinsulinemic (O-NI); and obese, hyperinsulinemic (O-HI) horses. Increasing BCS was associated with an increase in gene expression of a mitochondrial protein responsible for mitochondrial biogenesis (estrogen-related receptor alpha, ERRα) and with increased antioxidant enzyme total superoxide dismutase (TotSOD) activity. When groups (L-NI, O-NI, and O-HI) were compared, TotSOD activity was increased and protein carbonyls, a marker of oxidative damage, decreased in the O-HI compared to the L-NI horses. These findings suggest that a protective antioxidant response occurred in the muscle of obese animals and that obesity-associated oxidative damage in skeletal muscle is not central to the pathogenesis of equine hyperinsulinemia.

    Despite high prevalence and concerning associated problems, little effort has been made to conceptualize the construct of posttraumatic guilt. This investigation examined the theoretical model of trauma-related guilt proposed by Kubany and Watson (2003). This model hypothesizes that emotional and physical distress related to trauma memories partially mediates the relationship between guilt cognitions and posttraumatic guilt. Using path analysis, this investigation (a) empirically evaluated relationships hypothesized in Kubany and Watson's model, and (b) extended this conceptualization by evaluating models whereby guilt cognitions, distress, and posttraumatic guilt were related to posttraumatic stress disorder (PTSD) symptoms depression symptom severity. Participants were male U.S. Iraq and Afghanistan veterans (N = 149). Results yielded a significant indirect effect from guilt cognitions to posttraumatic guilt via distress, providing support for Kubany and Watson's model (β = .14). Findings suggested distress may be the strongest correlate of PTSD symptoms (β = .47) and depression symptoms (β = .40), and that guilt cognitions may serve to intensify the relationship between distress and posttraumatic psychopathology. Research is needed to evaluate whether distress specific to guilt cognitions operates differentially on posttraumatic guilt when compared to distress more broadly related to trauma memories.

    in both conditions, but was not different from pre-exercise. Reactive hyperaemia was reduced after no-EIHS but increased after EIHS. Thus, normalizing FMD to the shear stimulus (FMD/SR AUC ) revealed a significant reduction in FMD after EIHS only (pre-exercise 0.15 ± 0.04 and 0.13 ± 0.02 s -1 versus postexercise, 0.13 ± 0.02 and 0.06 ± 0.02 s -1 , no-EIHS and EIHS, respectively). We conclude that moderate heat stress superimposed on moderate-intensity exercise resulted in reduced vascular endothelial function. This heat stress-induced alteration in the shear-dilatory relationship may relate to the increased risk of acute coronary events associated with activities that combine physical exertion and heat stress (i.e. firefighting). © 2016 The Authors.

    This study examined the role of stress as a mediator of the relationship between prior drug addiction and current high-risk sexual behaviour. Eight hundred twenty women aged 18 to 30 years, who received care at community-based family planning clinics, were interviewed using the Composite International Diagnostic Interview and the Sexual Risk Behavior Assessment Schedule. They also completed the brief version of the Self-Control Scale as a measure of problem-solving strategies and measures of recent stressful events, daily hassles and ongoing chronic stress. Regardless of addiction history, stress exposure during the previous 12 months was associated with risky sexual behaviour during the previous 12 months. Structural equation modelling revealed that 12-month stress levels mediated the relationship between past drug addiction and 12-month high-risk sexual behaviours, as well as the negative relationship between problem-solving strategies and high-risk sexual behaviours. Problem-solving strategies did not moderate the relationship between drug addiction and high-risk sexual behaviours. These findings suggest that stress management training may help reduce risky behaviour among young, low-income women. Copyright © 2014 John Wiley & Sons, Ltd.

  2. Identification of stress responsive genes by studying specific relationships between mRNA and protein abundance

    Full Text Available Protein expression is regulated by the production and degradation of mRNAs and proteins but the specifics of their relationship are controversial. Although technological advances have enabled genome-wide and time-series surveys of mRNA and protein abundance, recent studies have shown paradoxical results, with most statistical analyses being limited to linear correlation, or analysis of variance applied separately to mRNA and protein datasets. Here, using recently analyzed genome-wide time-series data, we have developed a statistical analysis framework for identifying which types of genes or biological gene groups have significant correlation between mRNA and protein abundance after accounting for potential time delays. Our framework stratifies all genes in terms of the extent of time delay, conducts gene clustering in each stratum, and performs a non-parametric statistical test of the correlation between mRNA and protein abundance in a gene cluster. Consequently, we revealed stronger correlations than previously reported between mRNA and protein abundance in two metabolic pathways. Moreover, we identified a pair of stress responsive genes (ADC17 and KIN1 that showed a highly similar time series of mRNA and protein abundance. Furthermore, we confirmed robustness of the analysis framework by applying it to another genome-wide time-series data and identifying a cytoskeleton-related gene cluster (keratin 18, keratin 17, and mitotic spindle positioning that shows similar correlation. The significant correlation and highly similar changes of mRNA and protein abundance suggests a concerted role of these genes in cellular stress response, which we consider provides an answer to the question of the specific relationships between mRNA and protein in a cell. In addition, our framework for studying the relationship between mRNAs and proteins in a cell will provide a basis for studying specific relationships between mRNA and protein abundance after

    We conducted a cross-sectional survey of 4 primary care MetroNet centers in metropolitan Detroit. Our objective was to describe the causal role of fatigue in the relationship among stress, stress resiliency, and perceived health in primary care. Fatigue is a public health problem that has been linked to stress and poor health. The causal role of fatigue between stress and perceived health is unknown. Four hundred surveys were distributed to adult patients in 4 primary care centers in metropolitan Detroit between 2006 and 2007. Internal consistency reliabilities and principal factor analyses were calculated for the key psychological scales. Perceived health is the primary outcome. Path models were used to study the relationship among stress, fatigue, and perceived health. We also modeled the impact of select stress resiliency factors including sleep, recovery, and social support. Of the 400 distributed surveys, 315 (78.7%) had a response rate of 70% or more and were included in the analysis. Respondents were predominantly middle aged (median age, 43 years); female (58.7%); and African American (52.0%). The majority worked full time (56.5%); did not have a college degree (77.7%); and were not married (55.2%). Fatigue was reported by 59% of respondents, 42.7% of which was unexplained. The path model supported the causal role of fatigue between stress and perceived health. The positive effects of sleep, recovery, and social support on fatigue, stress, and perceived health were validated. Fatigue was common in this metropolitan primary care environment and completely mediated the relationship between stress and poor perceived health. Therefore, stress, when significant enough to cause fatigue, may lead to poor health.

    The nature and underlying mechanisms of the observed increased vulnerability to posttraumatic stress disorder (PTSD) in women are unclear. We investigated the genetic overlap of PTSD with anthropometric traits and reproductive behaviors and functions in women. The analysis was conducted using female-specific summary statistics from large genome-wide association studies (GWAS) and a cohort of 3577 European American women (966 PTSD cases and 2611 trauma-exposed controls). We applied a high-resolution polygenic score approach and Mendelian randomization analysis to investigate genetic correlations and causal relationships. We observed an inverse association of PTSD with genetically determined anthropometric traits related to body shape, independent of body mass index (BMI). The top association was related to BMI-adjusted waist circumference (WC adj ; R = -0.079, P body shape and PTSD, which could be mediated by evolutionary mechanisms involved in human sexual behaviors.

    The current study aimed to explore the association of cognitive emotion regulation, social support, resilience and acute stress responses in Chinese soldiers and to understand the multiple mediation effects of social support and resilience on the relationship between cognitive emotion regulation and acute stress responses. A total of 1477 male soldiers completed mental scales, including the cognitive emotion regulation questionnaire-Chinese version, the perceived social support scale, the Chinese version of the Connor-Davidson resilience scale, and the military acute stress scale. As hypothesized, physiological responses, psychological responses, and acute stress were associated with negative-focused cognitive emotion regulation, and negatively associated with positive-focused cognitive emotion regulation, social supports and resilience. Besides, positive-focused cognitive emotion regulation, social support, and resilience were significantly associated with one another, and negative-focused cognitive emotion regulation was negatively associated with social support. Regression analysis and bootstrap analysis showed that social support and resilience had partly mediating effects on negative strategies and acute stress, and fully mediating effects on positive strategies and acute stress. These results thus indicate that military acute stress is significantly associated with cognitive emotion regulation, social support, and resilience, and that social support and resilience have multiple mediation effects on the relationship between cognitive emotion regulation and acute stress responses.

    Objective: To evaluate the current status of job burnout and qual ity of work life (QWL) in workers for offshore oil platforms, and to analyze the relationship of job stress with job burnout and QWL and the direct and indirect effects of job stress on QWL. Methods: Cluster random sampling was used to select 382 work-ers for 8 oil platforms of China National Offshore Oil Corporation in October 2015. A self - designed questionnaire was used to collect the individual characteristics of subjects. The Quality of Work Life Scale (QWL7 - 32) , Occupa-tional Stress Inventory - Revised Edition (OSI - R) , and Maslach Burnout Inventory - General Survey (MBI - GS) were used to investigate the QWL, job stress, and job burnout of subjects. Results: Among all the workers for offshore oil platforms, 87.2% had mild job burnout. The total QWL score was 116.01 ± 16.73; 8.3% of the workers had poor QWL, and 68.5% had moderate QWL. QWL was reduced with heavier task, vaguer task, and increasing mental stress and physical stress ( P stress had di-rect and indirect effects on QWL; stress reaction had the most effect on QWL (total effect size - 0.509) , followed by social support (total effect size 0.444) . Conclusion: Most workers for offshore oil platforms have mild job burn-out and moderate QWL. Job stress is associated with job burnout and QWL, and stress reaction and social support have relatively high influence on QWL.

    The aim of this study is to explore the relationship between job stress and coping strategies of Hong Kong nurses working in an acute surgical unit. This is a descriptive correlational study. Data were collected from 98 Hong Kong surgical nurses using the Nursing Stress Scale and the Jalowiec Coping Scale. Results showed that workload (M = 15.36), lack of support (M = 13.32), and inadequate preparation (M = 12.33) are the most common stressors for Hong Kong surgical nurses. The most frequent strategies used by nurses to cope with stress can be characterized as evasive (M = 19.23), confrontive (M = 17.46), and optimistic (M = 15.81), all of which are also rated as the most effective strategies in reducing stress levels. Only the confrontive, optimistic, supportant, and emotive coping strategies reveal significant correlations (p stress levels of nurses, whereas the evasive, fatalistic, palliative, and self-reliant strategies showed no significant correlation with stress levels (p > .05). Recognizing the impacts of job-related stress and making use of effective coping methods play a vital role in reducing nurse's stress. A change in leadership styles from the managerial level and reallocation of manpower may help reduce job stress. The use of confrontive and optimistic coping strategies in reducing job-related stress for surgical nurses should be advocated and promoted in their daily work. Copyright © 2011 Elsevier Inc.

    Depression, anxiety and stress have been recognized as important mental outcome measures in stressful working settings. The present study explores the prevalence of self-perceived depression, anxiety and stress; and their relationships with psychosocial job factors. A cross-sectional study involving 728 male automotive assembly workers was conducted in two major automotive assembly plants in Malaysia using the validated Malay versions of the Depression Anxiety Stress Scales (DASS) and Job Content Questionnaire (JCQ). Based on the DASS cut-off of > or =78 percentile scores, the prevalence of self-perceived depression, anxiety and stress was 35.4%, 47.2% and 31.1%, respectively. Four (0.5%), 29 (4.0%) and 2 (0.3%) workers, respectively, reported extremely severe self-perceived depression, anxiety and stress. Multiple linear regression analyses, controlling for age, education, salary, duration of work and marital status, revealed that psychological job demand, job insecurity and hazardous condition were positively associated with DASS-Depression, DASS-Anxiety and DASS-Stress; supervisor support was inversely associated with DASS-Depression and DASS-Stress. We suggest that reducing psychological job demand, job insecurity and hazardous condition factors may improve the self-perceived depression, anxiety and stress in male automotive assembly workers. Supervisor support is protective for self-perceived depression and stress.

    A substantial literature has reported that stress negatively impacts on cognitive processes. As dementia caregiving can be stressful, it has been hypothesized that the challenges of dementia care may increase caregivers' own vulnerability to cognitive decline. Prefrontal processes are thought to be most vulnerable to stress; however, few studies have examined whether greater caregiver stress predicts poorer executive dysfunction, and no previous research has considered potential moderators of this relationship. We examined (1) whether greater psychological stress mediated a relationship between caregiver stress exposure and executive functioning and (2) whether greater self-efficacy and cognitive reserve (CR) moderated this relationship. Spousal dementia caregivers (n = 253) completed the Neuropsychiatric Inventory Questionnaire (stress exposure), the Perceived Stress Scale, the National Adult Reading Test (CR), the Fortinsky dementia-specific caregiver self-efficacy scale, and the Color Trails Test (executive functioning). Moderated mediation was tested using the PROCESS macro. Age, gender, and dementia risk factors were included as covariates. Greater stress exposure indirectly predicted executive functioning through psychological stress. Stronger relationships between greater psychological stress and poorer executive functioning were observed among caregivers with lower CR; there was no evidence that self-efficacy moderated the relationship between stress exposure and psychological stress. Our findings are in line with the idea that greater psychological stress in response to challenges associated with dementia care predicts poorer caregiver executive functioning, particularly among caregivers with low CR. However, these findings are cross sectional; it is also possible that poorer executive functioning contributes to greater caregiver stress.

    The goal of this study was to assess the relationship between emotion- and task-oriented coping (EOC/TOC) with stress and employment in patients undergoing maintenance hemodialysis. Individuals aged 18 to 64 yr who had uremia and had been undergoing hemodialysis regularly for at least three months were evaluated according to sociodemographic and clinical factors. Work status was defined using the most recent International Labour Organization definitions. Patients were requested to complete the following questionnaires: the Japanese version of the Coping Inventory for Stressful Situations, the Short Form-36 Health Survey, an item on itchiness, the Self-Efficacy on Health-Related Behavior Scale, the Japanese version of the Health Locus of Control Scale, the Social Support Scale, and the Japanese version of the Hospital Anxiety and Depression Scale. A total of 317 individuals participated in this study. Among men, age, physical functioning, EOC, and depression differed significantly (pTOC was not significantly associated with employment in either sex. Multiple logistic regression analyses, including possible confounders, indicated that when EOC increased by 10 points, the associated adjusted odds ratio of an unemployed or economically inactive status changed by 1.48 (95% confidence interval, 1.04-2.11; p=0.030) in men and by 1.88 (95% confidence interval, 1.02-3.46; p=0.042) in women. These results suggest that EOC is associated with employment in patients receiving maintenance hemodialysis.

    Stress coping is defined as a behavioral or cognitive response of an individual to uncomfortable or difficult situations. It has been suggested that coping, like personality, is related to the pathology and course of mental disorders. Accordingly, we here used a clinical sample to investigate the relationships between coping strategies and personality traits. Subjects were 60 outpatients who were in remission from major depressive disorder and who completed the Coping Inventory for Stressful Situations (CISS) and the Munich Personality Test (MPT). Task-oriented coping showed a positive correlation with extraversion and frustration tolerance. Emotion-oriented coping was closely associated with neuroticism, esoteric tendencies and isolation tendency. Avoidance-oriented coping was related to extraversion. Principal component analysis indicated three corresponding factors between coping and personality; one was related to psychopathology (loading from the neuroticism, esoteric tendencies and isolation tendency scales of the MPT, and from the emotion-oriented coping scale of the CISS), a second was a social-adaptive ability component (loading from the frustration tolerance and extraversion scales of the MPT, and from the task-oriented coping and avoidance-oriented coping scales of the CISS), and a third was a passive-avoidance coping component (loaded from the emotion-oriented coping and avoidance-oriented coping scales of the CISS only). Some personality traits such as extraversion and frustration tolerance are significantly related to task-oriented coping, and psychopathological personality traits such as neuroticism are associated with emotional-oriented coping in major depressive disorder.

    To explore the relationship between job satisfaction and occupational stress in the workers of a thermal power plant. The cluster sampling method was used to investigate 875 workers in a thermal power plant. The job satisfaction, occupational stressors, strains, personalities, meeting strategy and social support were measured using occupational stress instruments, job content questionnaire and effort-reward imbalance questionnaire. There were no significant differences of job satisfaction scores between different groups according to sex, educational level, marriage status, smoking and drinking (P > 0.05). But there were significant differences of job satisfaction scores between different age groups or between different service length groups (P responsibility for persons and things, promotion opportunity, job control, job stabilization, rewards, mental health, positive affectivity, self-esteem, superior support and coworker support scores (P responsibility for persons and things, promotion opportunity, job control, job stabilization, reward, mental health, positive affectivity, self-esteem and buffer scores of the workers with high job satisfaction scores were significantly higher than those of workers with moderate and lower job satisfaction scores (P four times as high as that for workers with high reward (OR = 3.773), the risks of job dissatisfaction for workers with low social support and mental locus of external work control were about two times as high as that for workers with high social support or mental locus of internal work control (OR = 2.419 and 2.219, respectively). The daily life stress, low control strategy, low support strategy, low job control and negative affectivity were risk factors of job dissatisfaction (OR = 1.125 approximately 1.790), but the self-esteem and positive affectivity could reduce the risk of job dissatisfaction.

    Spirituality and forgiveness have been shown to be associated with psychological well-being, while guilt has been associated with poor health. Little is known, however, about the relationship between forgiveness, spirituality, guilt, posttraumatic stress (PTSD) and psychological co-morbidity among people in recovery from addiction. Eighty-one people (F = 36, M = 45) in recovery from drug and alcohol addiction were recruited from two residential units and two drop-in centres in a city in the United Kingdom. They completed the Posttraumatic Stress Diagnostic Scale (PDS), the General Health Questionnaire-28 (GHQ-28), the Spiritual Involvement and Beliefs Scale (SIBS), the Heartland Forgiveness Scale (HFS), the Traumatic Guilt Inventory (TGI), the Michigan Alcoholism Screening Test (MAST-22) and the Drug Abuse Screening Test (DAST-20). The control group comprised of 83 (F = 34, M = 49) individuals who confirmed that they did not have addiction and completed the PDS & GHQ-28. 54 % of the addiction group met the criteria for full PTSD and reported anxiety, somatic problems and depression. They described themselves as spiritual, had strong feelings of guilt associated with their addiction, and had difficulty in forgiving themselves. Controlling for demographics, number of events and medication management, regression analyses showed that spirituality predicted psychological co-morbidity, whilst feelings of guilt predicted PTSD symptoms and psychological co-morbidity. Unexpectedly, forgiveness did not predict outcomes. This study supports existing literature, which shows that people with drug and alcohol addiction tend to have experienced significant past trauma and PTSD symptoms. Their posttraumatic stress reactions and associated psychological difficulties can be better understood in the light of guilt and spirituality. Meanwhile, their ability to forgive themselves or others did not seem to influence health outcomes.

    Growing evidence documents elevated behavioral risk among sexual-minorities, including gay, lesbian, and bisexual individuals; however, tests of biological or psychological indicators of stress as explanations for these disparities have not been conducted. Data were from the 2005-2010 National Health and Nutrition Examination Survey, and included 9662 participants; 9254 heterosexuals, 153 gays/lesbians and 255 bisexuals. Associations between sexual orientation and tobacco, alcohol, substance, and marijuana use, and body mass index, were tested using the chi-square test. Stress, operationalized as depressive symptoms and elevated C-reactive protein, was tested as mediating the association between sexual orientation and behavioral health risks. Multiple logistic regression was used to test for mediation effects, and the Sobel test was used to evaluate the statistical significance of the meditating effect. Gays/lesbians and bisexuals were more likely to report current smoking (p sexual orientation and current smoking (aOR 2.04, 95% CI 1.59, 2.63), lifetime history of substance use (aOR 3.30 95% CI 2.20, 4.96), and lifetime history of marijuana use (aOR 2.90, 95% CI 2.02, 4.16), among bisexuals only. C-reactive protein did not mediate the sexual orientation/behavior relationship. Higher prevalence of current smoking and lifetime history of substance use was observed among sexual minorities compared to heterosexuals. Among bisexuals, depressive symptoms accounted for only 0.9-3% of the reduction in the association between sexual orientation and marijuana use and tobacco use, respectively. More comprehensive assessments of stress are needed to inform explanations of the disparities in behavioral risk observed among sexual minorities.

    2012-11-10

    The incidence of severe maternal morbidity is increasing in high-income countries as a consequence, in part, of increased obstetric intervention and increasingly complex medical needs of women who become pregnant. Access to emergency obstetric care means that for the majority of women in these countries, an experience of severe maternal morbidity is unlikely to result in loss of life. However, little is known about the subsequent impact on postnatal psychological health resulting in an evidence gap to support provision of appropriate care for these women. There has recently been increasing recognition that childbirth can be a cause of post-traumatic stress disorder (PTSD). The combination of experiencing a life-threatening complication and its management may culminate in psychological trauma. This systematic review examined the association between women's experience of severe maternal morbidity during labour, at the time of giving birth or within the first week following birth, and PTSD and its symptoms. Relevant literature was identified through multiple databases, including MEDLINE, PsycINFO, EMBASE, CINAHL, British Nursing Index, Web of Science, Cochrane library and the British Library, using predetermined search strategies. The search terms included "post-traumatic stress disorder", "PTSD", "stress disorders, post-traumatic", "maternal morbidity", "pregnancy complications" "puerperal disorders", "obstetric labo(u)r complication", "postpartum h(a)emorrhage", "eclampsia". Studies identified were categorised according to pre-defined inclusion and exclusion criteria. The quality of included studies was assessed using the relevant CASP appraisal tools. Eleven primary studies met review criteria. Evidence of a relationship between severe maternal morbidity and PTSD/PTSD symptoms was inconsistent and findings varied between studies. Nevertheless, there is some evidence that severe pre-eclampsia is a risk factor for PTSD and its symptoms, an association possibly

    Cognitive Resource Theory (CRT) suggests that under high levels of stress, employees are more prone to committing indiscipline. As few studies have examined this relationship over time, the authors conducted a six-wave longitudinal study examining the relationship of soldiers' indiscipline with work demands and control. The study included archival data collected quarterly over 2 years from 1,701 soldiers representing 10 units in garrison (Germany and Italy), in training rotations (Grafenwoehr, Germany), and on peacekeeping deployments (Kosovo, Kuwait). No main effects were found for work overload, and the findings for the moderating effects of control were contradictory. Within each time point, as work overload increased, soldiers who felt less control committed more indiscipline, supporting CRT. Over time, however, as work overload increased, soldiers who perceived less control 6 months earlier committed less indiscipline. Additionally, the authors found reverse causal effects for control such that prior perceptions of a lack of control were associated with indiscipline and prior incidents of indiscipline with less control.

    Full Text Available The main purpose of this study is to assess the relationship between four bioclimatic indices for cattle (environmental stress, heat load, modified heat load, and respiratory rate predictor indices and three main milk components (fat, protein, and milk yield considering uncertainty. The climate parameters used to calculate the climate indices were taken from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA reanalysis from 2002 to 2010. Cow milk data were considered for the same period from April to September when the cows use the natural pasture. The study is based on a linear regression analysis using correlations as a summarizing diagnostic. Bootstrapping is used to represent uncertainty information in the confidence intervals. The main results identify an interesting relationship between the milk compounds and climate indices under all climate conditions. During spring, there are reasonably high correlations between the fat and protein concentrations vs. the climate indices, whereas there are insignificant dependencies between the milk yield and climate indices. During summer, the correlation between the fat and protein concentrations with the climate indices decreased in comparison with the spring results, whereas the correlation for the milk yield increased. This methodology is suggested for studies investigating the impacts of climate variability/change on food and agriculture using short term data considering uncertainty.

    Individual variation in the endocrine stress response has been linked to survival and performance in a variety of species. Here, we evaluate the relationship between the endocrine stress response and anti-predator behaviors in wild checkered puffers (Sphoeroides testudineus) captured at Eleuthera Island, Bahamas. The checkered puffer has a unique and easily measurable predator avoidance strategy, which is to inflate or 'puff' to deter potential predators. In this study, we measured baseline and stress-induced circulating glucocorticoid levels, as well as bite force, a performance measure that is relevant to both feeding and predator defence, and 'puff' performance. We found that puff performance and bite force were consistent within individuals, but generally decreased following a standardized stressor. Larger puffers were able to generate a higher bite force, and larger puffers were able to maintain a more robust puff performance following a standardized stressor relative to smaller puffers. In terms of the relationship between the glucocorticoid stress response and performance metrics, we found no relationship between post-stress glucocorticoid levels and either puff performance or bite force. However, we did find that baseline glucocorticoid levels predicted the ability of a puffer to maintain a robust puff response following a repeated stressor, and this relationship was more pronounced in larger individuals. Our work provides a novel example of how baseline glucocorticoids can predict a fitness-related anti-predator behavior. Copyright © 2015 Elsevier Inc. All rights reserved.

The primary presenting problem children report after disasters is posttraumatic stress symptoms (PTSS). Prior research suggests that PTSS is inversely related to social support, which is often disrupted after a disaster. Objective : This study examined the relationship between social support (from parents, teachers, and peers) and PTSS in children affected by Hurricane Katrina. The research contributes to the literature by examining the mechanisms that drive this relationship over time. Methods : In this study, 426 children were followed over four timepoints, beginning 3-7 months after Hurricane Katrina and concluding 25-27 months post-hurricane. Three path models analysed the relationship between social support (from parents, teachers, and peers, measured by the Social Support Scale for Children) and PTSS (measured by the UCLA PTSD Reaction Index). Covariates included child age, minority status, gender, perceived life threat, and actual life threat. Nonsignificant paths were trimmed from the final models. Global fit indices were examined to determine model fit. Results : In the parent and peer social support models, PTSS exhibited statistically significant effects on social support from one wave to the next. In the teacher model, this was only true between Waves 2 and 3. Social support showed a statistically significant effect on PTSS between Wave 2 and Wave 3 in the peer model (standardized estimate = -0.26, p  social support to PTSS were significant in the parent and teacher models. Conclusion : Findings support a social selection model in which PTSS undermine social support, particularly in the first two years post-disaster. If these findings are replicated, this suggests that, in cases of limited funding, PTSS should be prioritized, given their cascading effects on social support.

    This study aimed to determine the relationships between cognitive and emotional intelligence, coping and stress symptoms in the context of Type A personality pattern. The Raven Progressive Matrices, Emotional Intelligence Questionnaire, Ways of Coping Inventory, Stress Symptoms Scale, and Type A Personality Scale were administered to 271 university students. Two groups, Type As and Type Bs were created according to the Type A Personality Scale scores and were compared in terms of their scores on the other scales that were administered. Our analyses showed that stress symptoms were negatively correlated with effective coping, stress management, and general mood dimensions of the Emotional Intelligence Questionnaire. They were also positively correlated with ineffective coping and Type A behaviors. Being female also significantly predicted stress symptoms. When the participants were grouped according to Type A Personality Scale scores as Type As and Type Bs, the regression analysis showed that the stress symptoms of Type As were significantly predicted by the insufficient use of effective coping styles and deficiencies in the general mood component of emotional intelligence, whereas the stress symptoms of Type Bs were predicted by the insufficient use of effective coping styles, overuse of ineffective coping styles, and increase in the intrapersonal abilities component of emotional intelligence. Stress symptoms can be related to the variables associated with personality styles. It is suggested that stress management programs for Type As should include exercises that increase emotional intelligence, especially the components of drawing pleasure from their life situation, being more positive, hopeful and optimistic.

    Human factor can be affected by prevalence stress measured using Depression, Anxiety and Stress Scale (DASS). From the respondents feedback can be summarized that the main factor causes the highest prevalence stress is due to the working conditions that require operators to handle critical situation and make a prompt critical decisions. The relationship between the prevalence stress and performance shaping factors found that PSFFitness and PSFWork Process showed positive Pearson’s Correlation with the score of .763 and .826 while the level of significance, p = .028 and p = .012. These positive correlations with good significant values between prevalence stress and human performance shaping factor (PSF) related to fitness, work processes and procedures. The higher the stress level of the respondents, the higher the score of selected for the PSFs. This is due to the higher levels of stress lead to deteriorating physical health and cognitive also worsened. In addition, the lack of understanding in the work procedures can also be a factor that causes a growing stress. The higher these values will lead to the higher the probabilities of human error occur. Thus, monitoring the level of stress among operators RTP is important to ensure the safety of RTP.

    The sandwich generation represents adults, often in midlife, who care for both children and ageing parents/relatives. While the stress they experience has received some attention, little research has investigated the subjective well-being (SWB) of this population. This study examined the relationship between perceived stress and SWB and the moderating effect of coping style. Ninety-three participants (80 women), aged 23-63 years, completed an online survey measuring perceived stress, coping strategies, life satisfaction and positive and negative affect. Stress was negatively associated with SWB. While emotion- and problem-focused coping were directly associated with SWB outcomes, the only moderating effect found was for avoidance-focused coping (AFC). Specifically, AFC was associated with higher positive affect for those reporting lower stress. This study highlights the need to recognise the distinct circumstances that exist for the sandwich generation. Limitations and suggestions for future research are discussed. © 2017 AJA Inc.

    To determine the relationship between the frequency of work-related stress and prevalence of functional dyspepsia in a sample of 218 military older 50 years in 2010 in Lima Military Hospital Geriatric. Descriptive and explanatory study and for the data collection on stress, were used the Vital Events Scale Holmes-Rahe and clinical records for clinical and upper endoscopy registration that comply the criteria of Rome III for functional dyspepsia. For processing and data analysis the statistical software package SPSS (Statistical Package for Social Sciences) was used. 100% of military showed some level of work stress during the study year; thus, 36.7% had a high level, 31.2% medium or moderate level, and 32.1% had low stress level; these percentages medium and high stress levels accounted for 67.9%. These results establish that job stress is a common discomfort in the study population (tabulated Chi2 = 3.841, chi2 observed = 27,908). Regarding functional dyspepsia prevalence of 37.2%, which indicates that it is a common condition in those military (tabular Z = 1.96, Z c = 9.163) it was determined. There is a significant relationship between the frequency of work-related stress and prevalence of functional dyspepsia in military activity in older than 50 years (tabulated Chi2 = 5.991, chi2 observed = 28,878, contingency coefficient = 0.342).

    This study examined the array of associations among the emotional valence and the coherence of mothers' representations of their relationship with their toddlers, mothers' reported parenting stress, and toddlers' internalizing and externalizing behaviors. To evaluate maternal representations, 55 mothers were interviewed using the Five Minute Speech Sample procedure (FMSS; Magaña et al., 1986), which was coded for criticism and positive comments (Magaňa-Amato, 1993), as well as coherence (Sher-Censor & Yates, 2015). Mothers also completed the Parenting Stress Index - Short Form (PSI; Abidin, 1997) to evaluate their parenting stress and the Child Behavior Checklist (CBCL/1.5-5; Achenbach & Rescorla, 2000) to assess their toddlers' internalizing and externalizing behaviors. Results indicated that parenting stress was associated with maternal criticism and fewer positive comments in the FMSS, but not with the coherence of mothers' FMSS. Parenting stress, criticism, and lower coherence in the FMSS were associated with maternal reports of externalizing behaviors. Only parenting stress and lower coherence in the FMSS were related to mothers' reports of internalizing behaviors of the child. Thus, the emotional valence and the coherence of mothers' representations of their relationship with their child and parenting stress may each constitute a distinct aspect of parenting and contribute to the understanding of individual differences in toddlers' internalizing and externalizing behaviors. Implications for research and practice with families of toddlers are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Stress has been associated with poor self-control. Individual differences in impulsivity and other behavioral tendencies may influence the relationship of stress with self-control, although this possibility has not been examined to date. The present research investigated whether cumulative stress is associated with poor self-control, and whether this relationship is mediated by impulsivity, behavioral approach, and behavioral inhibition in men and women. A community sample of 566 adults (319 women and 247 men) was assessed on the Cumulative Adversity Interview, Brief Self-control Scale, Barratt Impulsivity Scale, and Behavioral Activation System and Behavioral Inhibition System Scale (BIS/BAS). Data were analyzed using regression and bootstrapping techniques. In the total sample, the effects of cumulative stress on self-control were mediated by impulsivity. Neither behavioral inhibition nor behavioral approach mediated the association between cumulative stress and self-control in the total sample. Results were similar when men and women were considered separately, with impulsivity, but not behavioral inhibition or approach, mediating the association between cumulative stress and self-control. Impulsive individuals might benefit preferentially from interventions focusing on stress management and strategies for improving self-control. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This observational paper endeavours to recognize the connection between spirituality and stress. Four types of indicators are utilized for the estimation of anxiety, vis-à-vis, behavioural indicators, emotional indicators, sleep indicators and personal habits. As per pre-documented theory, if spirituality is high within an individual, then his/her stress will be low and vice versa. In college, the stress of education and scoring grades influences the understudy. Information is gathered through a survey in the light of spirituality index and stress index. Findings prove that the indicators of the stress are more visible in female students. Apart from this, there has been not much substantial study in the area of stress and spirituality among college students. Hence, the main purpose of this study was to discuss the various types of stress and effects of spirituality on the engineering students belonging to the age group of 21-26 years, prioritizing the indicators of stress as per the gender of students. The entire study constituted of a sample group of 200 participants, and for the entire process, correlation analysis was used to find the relative relation between spirituality and stress among girls and boys. T test is used for rejection of the null hypothesis. The article focuses on the current issues that students have been facing in the twenty-first century. Result of the study showed that there is a negative relationship between the spirituality and stress of male and female students. Moreover, the article provides unique contribution to the literature and also offers suggestions for generating new research ideas that can be used to ameliorate the problems that plague individuals and organizations in today's world. This is the first article which covers the spirituality and stress of the engineering student and discusses the impact on young adults, as well as highlighting certain ways to overcome stress and enhance spirituality.

    Large numbers of United States service members and veterans are enrolling in colleges and universities. Many are experiencing posttraumatic stress symptoms secondary to their military service, and these symptoms are associated with academic dysfunction. However, little is known about the mechanism(s) through which posttraumatic stress increases risk for academic difficulties. The goal of the current study was to evaluate perceived interpersonal relationship quality as a mediator of this association. The current study investigated the indirect effect of posttraumatic stress on academic dysfunction through three indices of perceived interpersonal relationship quality (i.e., family distress, family support, and social network support) in a clinical sample of 2,120 student service members and veterans. Participants were further divided into four groups based on relationship status and gender (i.e., partnered women, nonpartnered women, partnered men, and nonpartnered men), and moderation by group was examined. For all four groups, there were significant indirect effects of posttraumatic stress on academic dysfunction through greater family distress and lower social network support. Further, the overall indirect effect of posttraumatic stress on academic dysfunction was stronger for partnered women compared with the three other groups and was attributable to the stronger path from family distress to academic dysfunction for partnered women. Poor perceived relationship quality may be a modifiable risk factor for academic dysfunction among student service members and veterans experiencing military-related posttraumatic stress. Partnered women may be especially well-suited to interventions that enhance the interpersonal context of posttraumatic stress as a way to optimize academic outcomes.

    Research has demonstrated associations between experiences of discrimination, relationship quality, and mental health. However, critical questions remain unanswered with regard to how stigma enacted and experienced at the dyadic-level influences relationship quality and mental health for transgender women and their cisgender (nontransgender) male partners. The present study sought to examine how experiences of transgender-related discrimination (i.e., unfair treatment, harassment) and relationship stigma (i.e., the real or anticipated fear of rejection based on one's romantic affiliation) were associated with both partners relationship quality and mental health. Couples (n = 191) were recruited to participate in cross-sectional survey. Dyadic analyses using actor-partner interdependence models were conducted to examine the influence of minority stressors on clinically significant depressive distress and relationship quality. For both partners, financial hardship, discrimination, and relationship stigma were associated with an increased odds of depressive distress. For both partners, financial hardship was associated with lower relationship quality. Among transgender women, their own and their partner's higher relationship stigma scores were associated with lower relationship quality; however, among male partners, only their partner's greater relationship stigma scores were associated with lower relationship quality. Findings provide preliminary support for dyadic crossover effects of relationship stigma on the health of partners. Findings illustrate the importance of minority stress and dyadic stress frameworks in understanding and intervening upon mental health disparities among transgender women and their male partners. Couples-based interventions and treatment approaches to help transgender women and their male partners cope with minority stressors are warranted to improve the health and well-being of both partners.

    Associations of specific types of stress with increased food intake and subsequent weight gain have been demonstrated in animal models as well as in experimental and epidemiological studies on humans. This study explores the research question of to what extent potentially obesity-related factors determine perceived stress in individuals with obesity. N = 547 individuals with obesity participated in a cross-sectional study assessing perceived stress as the outcome variable and potential determinants of stress related to obesity. Based on the available evidence, a five factorial model of 'obesity-related obesogenic stressors' was hypothesized, including the dimensions, 'drive for thinness', 'impulse regulation', 'ineffectiveness', 'social insecurity', and 'body dissatisfaction'. The model was tested using multiple linear regression analyses. The five factorial model of 'potentially obesity-related stressors' resulted in a total variance explanation of adjusted R² = 0.616 for males and adjusted R² = 0.595 for females for perceived stress. The relative variance contribution of the five included factors differed substantially for the two sexes. The findings of this cross-sectional study support the hypothesized, potentially obesity-related factors: 'drive for thinness', 'impulse regulation', 'ineffectiveness', 'social insecurity', and 'body dissatisfaction' as relevant determinants of perceived stress in individuals with obesity. © 2017 The Author(s) Published by S.

    Full Text Available Background and Objectives: Spiritual well-being has been recognized as an important resource to cope with illness and life stresses. The aim of this study is to determine the Spiritual well-being status as well as stress coping strategies in hemodialysis patients. Methods: This descriptive-analysis study included 95 randomly selected patients undergoing treatments with hemodialysis in hemodialysis centers of Qom hospitals. Data collection instruments were the Spiritual Well-Being Scale and Jalowiec Coping Scale Data were analyzed via SPSS 16 software, by using descriptive statistics, Pearson correlation coefficient and independent t-test. Results: The mean and standard deviation score of spiritual well-being of patients were 91.98±15.09 while the mean and standard deviation of existential and religious well-being were 50.76±8.06 and 41.22±8.91, respectively. 52.6% got scores higher than the average score in spiritual well-being. The most common coping strategies in patients were Evasive and Supportant copings. Spiritual well-being and problem-oriented coping strategies had a significant positive correlation (r = 0.41, p = 0.008. But there was no significant relationship between spiritual well-being and emotion-focused coping strategies. Conclusion: Results showed that hemodialysis patients mostly use emotion-oriented strategies when facing disease and treatment’s challenges. There was a positive relation between spiritual well-being and problem-oriented coping strategies; therefore, in order to increase levels of coping with the disease, the care plan should be written with an emphasis on patients' spiritual needs.

    The aim of the present study was to examine the relationship between objective data of physical activity and markers of oxidative stress in older men and women. Participants were old adults, aged≥60years (61 women and 34 men) who were all capable of performing basic daily activities by themselves and lived on their own. To describe physical activity we used objective data measured by accelerometers which record active and sedentary periods during everyday life for five days. Determination of oxidative stress was conducted from three perspectives: determination plasma total antioxidant status (TAS), plasma antioxidant enzyme activities, i.e., glutathione peroxidase (GPx), catalase (CAT) and superoxide dismutase (SOD), and membrane lipid peroxidation (TBARS). In the group of women, those who met physical activity recommendations (WR) had lower level of TAS. In addition, the moderate to vigorous physical activity (MVPA) was negatively correlated with TAS. Simultaneously, MVPA was correlated with increase in the GPx antioxidant enzyme activity, and the counts per minute were positively correlated with CAT activity. In the group of men, the cpm and the MVPA were negatively correlated with lipid peroxidation while lifestyle physical activity was positively correlated with CAT activity. These findings suggest that MVPA in the elderly although it is related to a decrease in the TAS in women, induces adaptive increase in antioxidant enzyme activity and decreases lipid peroxidation in both women and men. These results suggest that at this time of life, it is not only the amount of physical activity performed that is important but also its intensity. Copyright © 2015 Elsevier Inc.

    Full Text Available Background: Posttraumatic stress disorder (PTSD is a stress disorder, whose prevalence was 2-15%. PTSD is associated with mood, anxiety, personality and substance use disorders (SUD. The substance user patients with PTSD have more problems, and severity of symptoms is more than non-substance users with PTSD patients. These patients may be nervous, aggressive, and restless and their function will be affected in many aspects. The aim of this study was to determine the relationship between aggression levels and substances use among PTSD patients. Methods: Among patients with PTSD referred to Kermanshah Farabi Hospital in 2011,182 cases were selected and their aggression levels were assessed by Buss & Perry Aggression Questionnaire. The aggression levels in PTSD patients with and without SUD were compared. Result: The highest frequencies were in middle-aged (81.1%, males (91.8%, married (77.5% and poor economic status (63.2% patients. Substances using was higher among married patients and the most abused substances was opium. Substances consumption was higher among patients with lower socioeconomic status and opium and amphetamines were the most abused substance. Most PTSD types were related to after-war events (70.3%. Mean of total aggression was higher in SUD. Rate of total aggression was higher in patients using opium. Conclusion: Compared to those without PTSD, individuals with this disorder are more likely to have aggression. Patients with concurrent PTSD and SUD suffer from more severe complaints and show worse treatment outcomes compared with patients with either disorder alone.

  20. The Cortisol Awakening Response Mediates the Relationship Between Acculturative Stress and Self-Reported Health in Mexican Americans.

    2017-12-01

    The assessment of acculturative stress as synonymous with acculturation level overlooks the dynamic, interactive, and developmental nature of the acculturation process. An individual's unique perception and response to a range of stressors at each stage of the dynamic process of acculturation may be associated with stress-induced alterations in important biological response systems that mediate health outcomes. Evidence suggests the cortisol awakening response (CAR) is a promising pre-clinical biomarker of stress exposure that may link acculturative stress to self-reported health in Mexican Americans. The aim of the current study was to examine whether alterations in the CAR mediate the relationship between acculturative stress and self-reported health in Mexican Americans. Salivary cortisol samples were collected at awakening, 30, 45, and 60 min thereafter, on two consecutive weekdays from a sample of adult Mexican Americans. Acculturative stress and self-reported health were assessed. Data were aggregated and analyzed (n = 89) using a mixed effects regression model and path analysis. Poorer self-reported health was associated with attenuated CAR profiles (primarily due to a diminished post-awakening rise in cortisol) predicted by both moderate and high levels of exposure to acculturative stress. Stress-induced alterations in the CAR mediated the relationship between exposure to acculturative stressors and self-reported health. Findings demonstrate that different levels of acculturative stress are associated with distinct CAR profiles and suggest the CAR is one possible biological pathway through which exposure to culturally unique stressors may be linked to health disparities.

    2016-01-01

    Objective Posttraumatic stress disorder (PTSD) is associated with both aggressive and suicidal behavior. Recent research suggests that the diagnosis of Intermittent Explosive Disorder (IED), an impulse-control disorder characterized by repeated impulsive aggressive behavior, may help to identify individuals at risk for attempting suicide. Given the relationship between anger and PTSD, there is likely to be an increased prevalence of IED among individuals with PTSD; however, little is known about the overlap in these two disorders, including how individuals with comorbid IED and PTSD may differ from those with either disorder alone. The purpose of this study is to examine the clinical correlates of comorbid IED and PTSD and the contribution of these two disorders (among others) to lifetime suicide attempt and characteristics of suicidal behavior. Method In a large sample of community research volunteers (N=1460), we compared individuals with PTSD, IED, and comorbid PTSD and IED on measures of current mood, trait aggression, and trait impulsivity. We also examined the contributions of PTSD, IED, and other syndromal and personality disorders to the prediction of lifetime aggression and lifetime suicide attempt, and their relationship to characteristics of suicide attempts, including level of intent, use of violent versus non-violent means, and the medical seriousness of the attempt. Results Comorbid PTSD and IED was associated with significantly elevated levels of depression, anxiety, anger, aggression, and impulsivity, as well as with high rates of comorbidity with other psychiatric disorders. IED (β=.56, psuicide attempt in multivariate analysis (ORs: 1.6 and 1.6, pssuicide attempt (41.4% in this sample). Conclusion These findings add support to the notion that the diagnosis of IED may aid in identifying individuals at risk for aggressive and suicidal behavior. PMID:27624432

    Post traumatic cognitions (PTCs) are important determinants of post traumatic stress symptoms (PTS symptoms). We tested whether risk factors of PTS symptoms (trauma, demographics, social and family-related factors) predict PTCs and whether PTCs mediate the association between risk factors and PTS symptoms among war-affected children. The participants were 240 Palestinian children 10-12 years old, half boys and half girls, and their parents. Children reported about psychological maltreatment, sibling and peer relations, war trauma, PTCs, PTS symptoms, and depression. Parents reported about their socioeconomic status and their own PTS symptoms. The associations between the variables were estimated in structural equation models. In models which included all the variables, PTCs were predicted by and mediated the effects of psychological maltreatment, war trauma, sibling conflict, and peer unpopularity on PTS symptoms. Other predictors had statistically non-significant effects. Psychological maltreatment had the largest indirect effect (b* = 0.29, p = 0.002) and the indirect effects of war trauma (b* = 0.10, p = 0.045), sibling conflict (b* = 0.10, p = 0.045), and peer unpopularity (b* = 0.10, p = 0.094) were lower and about the same size. Age-salient social relationships are potentially important in the development of both PTCs and PTS symptoms among preadolescents. Furthermore, PTCs mediate the effects of the risk factors of PTS symptoms. The causality of the associations among the variables is not established but it could be studied in the future with interventions which improve the negative aspects of traumatized children's important social relationships.

    While Veterans in general are no more dangerous than the civilian population, Veterans with posttraumatic stress disorder (PTSD) have stronger associations with anger and hostility and certain forms of aggression, such as intimate partner violence, than civilians with PTSD. This is alarming because up to 21% of Veterans seeking Veterans Affairs (VA) health care are diagnosed with PTSD. Emotion regulation difficulties (emotion dysregulation) are also related to increased PTSD symptom severity and may play a role in aggressive behavior. Because the predominant form of aggression in PTSD appears to be the impulsive subtype, the authors sought to clarify the relationship between PTSD, emotion dysregulation, and impulsive aggression. We examined how emotion dysregulation influenced impulsive aggression in a Veteran sample (N = 479) seeking treatment for trauma sequelae. All Veterans completed measures that assessed demographic information, emotion dysregulation, aggression frequency and subtype, and PTSD symptoms. Men generally reported more aggression than women. The emotion dysregulation, aggression, and PTSD measures were significantly correlated. Two cross-sectional mediation models showed emotion dysregulation fully accounted for the relationship between PTSD and impulsive aggression (indirect path for men: b = .07, SE = .026, bias-correct and accelerated confidence interval [BCa CI] = [0.02, 0.13]; indirect path for women: b = .08, SE = .022, BCa CI = [0.05, 0.13]). PTSD can increase negative emotions yet does not always lead to aggressive behaviors. The ability to regulate emotions may be pivotal to inhibiting aggression in those with PTSD. PTSD interventions may benefit from augmentation with emotion regulation skills training. © The Author(s) 2015.

    To compare fracture risk in persons with and without HIV infection and to examine the influence of highly active antiretroviral therapy (HAART) initiation on risk of fracture. Population-based nationwide cohort study using Danish registries. Outcome measures were time to first fracture at any site, time to first low-energy and high-energy fracture in HIV-infected patients (n = 5306) compared with a general population control cohort (n = 26 530) matched by sex and age during the study period 1995-2009. Cox regression analyses were used to estimate incidence rate ratios (IRRs). HIV-infected patients had increased risk of fracture [IRR 1.5, 95% confidence interval (CI) 1.4-1.7] compared with population controls. The relative risk was lower in HIV-monoinfected patients (IRR 1.3, 95% CI 1.2-1.4) than in HIV/hepatitis C virus (HCV)-coinfected patients (IRR 2.9, 95% CI 2.5-3.4).Both HIV-monoinfected and HIV/HCV-coinfected patients had increased risk of low-energy fracture, IRR of 1.6 (95% CI 1.4-1.8) and 3.8 (95% CI 3.0-4.9). However, only HIV/HCV-coinfected patients had increased risk of high-energy fracture, IRR of 2.4 (95% CI 2.0-2.9). Among HIV-monoinfected patients the risk of low-energy fracture was only significantly increased after HAART exposure, IRR of 1.8 (95% CI 1.5-2.1). The increased risk in HAART-exposed patients was not associated with CD4 cell count, prior AIDS, tenofovir or efavirenz exposure, but with comorbidity and smoking. HIV-infected patients had increased risk of fracture compared with population controls. Among HIV-monoinfected patients the increased risk was observed for low-energy but not for high-energy fractures, and the increased risk of low-energy fracture was only observed in HAART-exposed patients.

    In order to evaluate the relationship of quality of life (QOL) with physical fitness, competence and stress response in the elderly population in Japan, a cross sectional field survey of elderly subjects was conducted. This survey was taken in Naguri village, Saitama. The data collected included physical fitness, competence, stress response and QOL in addition to demographic variables. As for physical fitness indexes, grip strength (GS), single leg balance with eyes closed (SLB), bar grip ping reaction time (RT), trunk flexion (RF), ten-meter walking time (WT) and vital capacity (VC) were measured. The SF-36 was used for QOL assessment. A total of 120 elderly subjected participated to the survey. There were 42 males (73.5 +/- 5.74 years) and 78 females (74.2 +/- 6.17 years). The associations between physical health parameters in SF-36 and WT were highly significant: physical functioning (beta = -2.96, p fit indexes of the structural equation model describing the relationships among physical fitness, competence, stress response and QOL indicated excellent fit to the data with GFI = 0.95 and AGFI = 0.88. Stress response showed relatively stronger influence on QOL than physical fitness or competence. Although there were slight differences in degree of influence, physical fitness, stress response and competence were found to be clearly related to QOL in elderly subjects. To keep good QOL status, it is important to maintain good physical fitness and level of competence and to reduce stress response.

    This study analyzes the role of Perceived Emotional Intelligence (PEI) on sources of job stress and mental health in 250 elementary school teachers from Jaén (Spain). The aim of the study was two-fold: (1) to analyze the associations between Perceived Emotional Intelligence (PEI), sources of occupational stress and mental health; and (2) to determine whether PEI moderates the relationship between sources of occupational stress and mental health. An initial sample of 250 teachers was assessed Three questionnaires, the Trait Meta-Mood Scale, the Sources of Stress Scale in Teachers and the Medical Outcomes Study 36-item Short Form Health Survey, were used to evaluate PEI, sources of occupational stress and mental health, respectively. Teachers with higher levels of emotional attention reported lower levels of mental health (r = -.30; p relationship between sources of occupational stress and emotional role. Specifically, each significant interaction (i.e., deficiencies x attention, adaptation x attention, and adaptation x clarity) made a small and unique contribution in the explanation of emotional role (all p < .05, all sr 2 ∼ .02). Finally, our results imply that PEI is an important moderator of teachers´ occupational stressors on mental health.

    This study investigated sensory processing in a sample of Spanish children with autism spectrum disorder (ASD). Specifically, the study aimed to explore (1) the prevalence and distribution of atypical sensory processing patterns, (2) the relationship between adaptive and maladaptive behaviour with atypical sensory processing and (3) the possible relationship between sensory subtype and maternal stress. The short sensory profile 2 (Dunn 2014) and the vineland adaptive behavior scale (Sparrow et al. 1984) were administered to examine the sensory processing difficulties and maladaptive behaviours of 45 children with ASD aged 3 to 14; their mothers also completed the parenting stress index-short form (Abidin 1995). Atypical sensory features were found in 86.7% of the children; avoider and sensor being the two most common patterns. No significant relationship was found between atypical sensory processing and adaptive behaviour. However, the analysis showed a strong relationship between sensory processing and maladaptive behaviour. Both maladaptive behaviour and sensory processing difficulties correlated significantly with maternal stress although maternal stress was predicted only by the sensory variable, and in particular by the avoider pattern. The findings suggest that sensory features in ASD may be driving the high prevalence of parental stress in carers. They also suggest that the effect on parental stress that has been attributed traditionally to maladaptive behaviours may be driven by sensory difficulties. The implications of these findings are discussed in relation to the development of interventions and the need to explore contextual and cultural variables as possible sources of variability. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

    Asphalt binder is responsible for the thermo-viscoelastic mechanical behavior of asphalt concrete. Upon application of pure compressive stress to an asphalt concrete specimen, the stress is transferred by mechanisms such as aggregate interlock and the adhesion/cohesion properties of asphalt mastic. In the pure tensile stress mode, aggregate interlock plays a limited role in stress transfer, and the mastic phase plays the dominant role through its adhesive/cohesive and viscoelastic properties. Under actual combined loading patterns, any coordinate direction may experience different stress modes; therefore, the mechanical behavior is not the same in the different directions and the asphalt specimen behaves as an anisotropic material. The present study developed an anisotropic nonlinear viscoelastic constitutive relationship that is sensitive to the tension/compression stress mode by extending Schapery's nonlinear viscoelastic model. The proposed constitutive relationship was implemented in Abaqus using a user material (UMAT) subroutine in an implicit scheme. Uniaxial compression and indirect tension (IDT) testing were used to characterize the viscoelastic properties of the bituminous materials and to calibrate and validate the proposed constitutive relationship. Compressive and tensile creep compliances were calculated using uniaxial compression, as well as IDT test results, for different creep-recovery loading patterns at intermediate temperature. The results showed that both tensile creep compliance and its rate were greater than those of compression. The calculated deflections based on these IDT test simulations were compared with experimental measurements and were deemed acceptable. This suggests that the proposed viscoelastic constitutive relationship correctly demonstrates the viscoelastic response and is more accurate for analysis of asphalt concrete in the laboratory or in situ.

    The goal of the present study was to examine the relationships of depression, anxiety and stress with bone mineral density (BMD). We hypothesized negative relations between those mood variables and BMD in three assessed areas. The study showed association between depression and decreased BMD. The hypothesis regarding anxiety and stress was partially confirmed. In the last decade, the relationship of osteoporosis to psychological variables has been increasingly studied. The accumulating evidence from these studies supports the conclusion that depression is related to decreased BMD. Nevertheless, several studies found no support for this relationship. Moreover, only a small number of studies examined the association between anxiety or stress and decreased BMD. The goal of the present study was to examine the relationships of depression, anxiety and stress with BMD by means of adequate measuring instruments, while controlling for background factors known to be related to BMD decrease (e.g., body mass index, family history). The study included 135 post-menopausal female participants, who arrived for BMD screening, between the years 2006 and 2009. Several days prior to the examination, participants completed a series of questionnaires assessing depression and anxiety. BMD was measured using DXA, in spine, right and left hip. The study showed negative associations between depression and BMD variables in the three assessed areas. There were negative correlations between anxiety, stress and spine BMD, as well as a tendency towards negative relations in the right and left hip BMD. Concurrent hierarchical regressions showed that the addition of the three psychological variables increased the explained variance by 6–8 %. In addition, depression was found to have a unique significant contribution to the explained variance in right and left hip BMD. The findings provide supporting evidence for the existence of associations between mood variables and decreased BMD. Further

    Full Text Available This study aimed to explore the relationships between vulnerability to labour stress and job satisfaction in a sample of people with hearing loss. 54 people were attended, all workers aged between 18 and 58 years (M=30.37. Escala de Vulnerabilidade ao Estresse Laboral (EVENT and Escala de Satisfação no Trabalho (EST were applied, and the application process involved a researcher who communicates by Brazilian Signs Language (LIBRAS. The results showed low and moderate negative correlations between the tests. Men had higher scores on the EVENT and the women in the EST. People who speak LIBRAS had the highest averages in the EST, while the others scored more on EVENT. It was found that the longer in the same company, the greater the tendency to be more vulnerable and less satisfied. It is concluded that further studies should be done in order to evaluate other variables intertwined in the process of inclusion of people with hearing loss.

    Posttraumatic stress disorder (PTSD) is frequently linked with substance abuse. The self-medication hypothesis suggests that some people may use illicit substances in an attempt to self-treat psychiatric symptoms. This study explores the relationship between substance abuse and PTSD symptom clusters in a methadone maintenance population. Clients of a methadone maintenance program at a public Drug and Alcohol Service were invited to complete the PTSD Checklist-Civilian Version, a screening tool for PTSD. Information about their history of substance use was also collected. Eighty clients (43 female, 37 male), aged 35 ± 8.0 years (mean ± SD), participated in the study, of which 52.7% screened positive for PTSD. Severity of marijuana use was significantly associated with a number of reexperiencing and hyperarousal symptoms and with overall severity of PTSD symptoms. Opiate, amphetamine, and benzodiazepine use did not appear to be related to PTSD symptoms. In this sample, marijuana may be used to self-treat certain PTSD symptoms, supporting the self-medication hypothesis. Further research is required to confirm the association between a diagnosis of PTSD and substance use. Given the high prevalence of PTSD in the substance-using population, routine PTSD screening in the substance abuse treatment setting may be justified. Copyright © 2011 Elsevier Inc.

    The purpose of this study was to examine the relationship and predictive power of various psychosocial job stressors for the 3 dimensions of burnout in emergency departments. This study was structured as a cross-sectional design, with a questionnaire as the tool. The data were gathered using an anonymous questionnaire in 3 hospitals in Spain. The sample consisted of 191 emergency departments. Burnout was evaluated by the Maslach Burnout Inventory and the job stressors by the Nursing Stress Scale. The Burnout Model in this study consisted of 3 dimensions: emotional exhaustion, cynicism, and reduced professional efficacy. The model that predicted the emotional exhaustion dimension was formed by 2 variables: Excessive workload and lack of emotional support. These 2 variables explained 19.4% of variance in emotional exhaustion. Cynicism had 4 predictors that explained 25.8% of variance: Interpersonal conflicts, lack of social support, excessive workload, and type of contract. Finally, variability in reduced professional efficacy was predicted by 3 variables: Interpersonal conflicts, lack of social support, and the type of shift worked, which explained 10.4% of variance. From the point of view of nurse leaders, organizational interventions, and the management of human resources, this analysis of the principal causes of burnout is particularly useful to select, prioritize, and implement preventive measures that will improve the quality of care offered to patients and the well-being of personnel.

    Stress proliferation theory suggests that parental incarceration may have deleterious intergenerational health consequences. In this study, I use data from the 2011-2012 National Survey of Children's Health (NSCH) to estimate the relationship between parental incarceration and children's fair or poor overall health, a range of physical and mental health conditions, activity limitations, and chronic school absence. Descriptive statistics show that children of incarcerated parents are a vulnerable population who experience disadvantages across an array of health outcomes. After adjusting for demographic, socioeconomic, and familial characteristics, I find that parental incarceration is independently associated with learning disabilities, attention deficit disorder and attention deficit hyperactivity disorder, behavioral or conduct problems, developmental delays, and speech or language problems. Taken together, results suggest that children's health disadvantages are an overlooked and unintended consequence of mass incarceration and that incarceration, given its unequal distribution across the population, may have implications for population-level racial-ethnic and social class inequalities in children's health. © American Sociological Association 2014.

    Rational Emotive Behaviour Therapy (REBT) assumes that rational beliefs act as cognitive protective factors against the development of psychopathology; however little empirical evidence exists regarding the nature of the possible protective effects that they offer. The current study investigates whether rational beliefs moderate the impact of irrational beliefs on posttraumatic stress symptomology (PTS). Three hundred and thirteen active law enforcement, military, and related emergency service personnel took part in the current study. Sequential moderated multiple regression analysis was employed to investigate: (i) the direct impact of irrational beliefs on PTS; (ii) the direct impact of rational beliefs on PTS; (iii) the moderating effects of rational beliefs in the relationship between irrational beliefs and PTS. The irrational beliefs predicted by REBT theory emerged as critical predictors of PTS symptomology, in particular Depreciation beliefs. Rational beliefs (Preferences, and Acceptance beliefs) had a direct, negative impact on levels of PTS, and Acceptance beliefs moderated the impact of Catastrophizing beliefs on PTS. Irrational beliefs are important cognitive vulnerability factors in symptoms of PTS, while rational beliefs (Acceptance) appear to have a protective role in the emergence of PTS symptoms, both directly and by moderating the impact of Catastrophizing beliefs.

    While many studies have identified a significant relation between child maltreatment and adolescent substance use, the developmental pathways linking this relation remain sparsely explored. The current study examines posttraumatic stress (PTS) symptoms, mother-child relationships, and internalizing and externalizing problems as potential longitudinal pathways through which child maltreatment influences adolescent substance use. Structural equation modeling was conducted on 883 adolescents drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). The pathways of PTS symptoms linked physical and sexual abuse to substance use, and the pathways of mother-child relationships linked emotional abuse and neglect to substance use. None of the four types of maltreatment affected substance use via internalizing or externalizing problems. The findings suggest that intervention efforts aimed at addressing posttraumatic stress symptoms and improving mother-child relationship quality may be beneficial in reducing substance use among adolescents with child maltreatment histories.

    We study the statistics of wind-driven open ocean currents. Using the Ekman layer model for the integrated currents, we investigate analytically and numerically the relationship between the wind-stress distribution and its temporal correlations and the statistics of the open ocean currents. We found that temporally long-range correlated winds result in currents whose statistics is proportional to the wind-stress statistics. On the other hand, short-range correlated winds lead to Gaussian distributions of the current components, regardless of the stationary distribution of the winds, and therefore to a Rayleigh distribution of the current amplitude, if the wind stress is isotropic. We found that the second moment of the current speed exhibits a maximum as a function of the correlation time of the wind stress for a non-zero Coriolis parameter. The results were validated using an oceanic general circulation model. (paper)

    2013-01-01

    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.

    Adolescence and young adulthood are developmental periods during the life course that are sometimes associated with heightened stress and engagement in binge eating. Binge eating has been linked to psychiatric comorbidity, poorer physical health, and lower quality of life. However, less is known about protective factors that could buffer against binge eating behaviors. The current study examined the moderating role of resilience on the relationship between perceived stress and binge eating symptoms among emerging adult female college students. Participants were 297 young adult women aged 18-25 years (M age  = 19.22, SD = 1.51; 52% self-identifying as a racial/ethnic minority) with Body Mass Index ranging from 15 to 66 (M BMI  = 25.01, SD = 6.18). Women completed this cross-sectional study while they were attending universities in the Western or Southern United States. Participants provided demographic and height/weight information, and completed the following measures: Perceived Stress Scale, Binge Eating Scale, and Brief Resilience Scale. Higher perceived stress was significantly associated with more severe binge eating symptoms (b = 0.31; p relationship between perceived stress and binge eating symptoms varied by resilience level (b = -0.16; p stress were more likely to engage in binge eating relative to women experiencing low stress; however, resilience attenuated this association. Resilience could be targeted to reduce the negative effects of perceived stress on eating behaviors in young women. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The variation between rest and peak stress end-systolic pressure-volume relation is an afterload-independent index of left ventricular contractility. Whether and to what extent it depends on end-diastolic volume remains unclear. The aim of this study was to assess the dependence of the delta rest-stress end-systolic pressure-volume relation on end-diastolic volume in patients with negative stress echo and all ranges of resting left ventricular function. We analyzed interpretable data obtained in 891 patients (593 men, age 63 ± 12 years) with ejection fraction 47% ± 12%: 338 were normal or near-normal or hypertensive; 229 patients had coronary artery disease; and 324 patients had ischemic or nonischemic dilated cardiomyopathy. They were studied with exercise (n = 172), dipyridamole (n = 482) or dobutamine (n = 237) stress echocardiography. The end-systolic pressure-volume relation was evaluated at rest and peak stress from raw measurement of systolic arterial pressure by cuff sphygmomanometer and end-systolic volume by biplane Simpson rule 2-dimensional echocardiography. Absolute values of delta rest-stress end-systolic pressure-volume relation were higher for exercise and dobutamine than for dipyridamole. In the overall population, an inverse relationship between end-systolic pressure-volume relation and end-diastolic volume was present at rest (r 2 = 0.69, P stress (r 2 = 0.56, P stress end-systolic pressure-volume relation was considered (r 2 = 0.13). Left ventricular end-diastolic volume does not affect the rest-stress changes in end-systolic pressure-volume relation in either normal or abnormal left ventricles during physical or pharmacological stress.

    Ford, Denise Marie

    Students identified as gifted come from varying socio-economic strata and nationalities with a range of talents and temperaments comprising a diverse community. They may experience stress for a variety of reasons. Although a certain amount of stress can enhance the learning process, too much stress can impede learning, especially memory. Strategies have been offered for relieving stress, yet the benefits of physical activities as stress reducers for the gifted have frequently been overlooked. The purpose of this study was to investigate the relationship among aerobic activity, stress, and memory ability in students in an elementary school gifted program. An exceptional aspect of this research was that the students were an integral part of their own study. As co-researchers they had a vested interest in what they were doing, enhancing the significance of the experience and heightening learning. This action research project conducted in a mid-western school district with fourth and fifth grade students examined the impact of aerobic movement on physical indicators of stress and memory. The study lasted twelve weeks with data collected on physical indicators of stress, memory test scores, parent observations, interviews with students, a parent focus group session, observational data, student comments, and investigator/teacher journal. By infusing regular exercise into curricula, stress levels in students identified as gifted were examined. Students' scores on declarative memory tasks conducted with and without an accompanying aerobic activity were documented. Students learned of the delicate relationship between stress and memory as they studied the physiology of the brain. Twenty-four hour retention rates of declarative memory items were higher when a 20-minute aerobic activity intervention preceded the memory activity. Perceived stress levels were lowered for 14 of the 16 co-researchers. Students indicated a positive attitude toward physical activity and its

    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.

    Past research has shown that higher stress is associated with increased burnout symptoms. The purpose of this study was to test whether mental toughness protects against symptoms of burnout and whether mental toughness moderates the relationship between perceived stress and burnout over time. Fifty-four vocational students (M age = 18.1 yr., SD = 1.2; 27 males, 27 females) completed self-report questionnaires twice, 10 mo. apart. Perceived stress, mental toughness, and burnout were measured using the Adolescent Stress Questionnaire (ASQ), the Mental Toughness Questionnaire (MTQ), and the Shirom-Melamed Burnout Measure (SMBM). Students who perceived higher stress and lower mental toughness scores reported higher burnout symptoms. Although no significant interaction effects were found between stress and mental toughness in the prediction of burnout, the graphical inspection of the interactions indicated that among students with high stress, those with high mental toughness remained below the cutoff for mild burnout, whereas an increase in burnout symptoms was observable among peers with low mental toughness.

    This study investigated associations among young adults' hypothalamic-pituitary-adrenal axis activity, autonomic nervous system activity, and subjective stress in response to interpersonal conflict to better characterize coordination across stress systems. Seven saliva samples were collected from 199 young adult opposite-sex couples before, during, and after they discussed an unresolved relationship conflict. Samples were later assayed for cortisol and alpha-amylase (sAA). Couples rated anticipatory stress prior to the conflict and perceived stress immediately following the task. Growth curve modeling was used to examine two possible levels of within-person coordination across physiological systems: alignment between cortisol and sAA responses throughout the sampling period ("matched phase coordination"), and association between overall levels of cortisol and sAA in response to conflict ("average level coordination"). Whereas both partners showed the former type of coordination, only women showed the latter type. Positive anticipation of the stressor predicted stronger cortisol-sAA matched phase coordination for women. Pre-task ratings related to women's sAA, and post-task ratings related to both partners' cortisol responses.

    This study investigated associations among young adults' hypothalamic-pituitary-adrenal axis activity, autonomic nervous system activity, and subjective stress in response to interpersonal conflict to better characterize coordination across stress systems. Seven saliva samples were collected from 199 young adult opposite-sex couples before, during, and after they discussed an unresolved relationship conflict. Samples were later assayed for cortisol and alpha-amylase (sAA). Couples rated anticipatory stress prior to the conflict and perceived stress immediately following the task. Growth curve modeling was used to examine two possible levels of within-person coordination across physiological systems: alignment between cortisol and sAA responses throughout the sampling period (“matched phase coordination”), and association between overall levels of cortisol and sAA in response to conflict (“average level coordination”). Whereas both partners showed the former type of coordination, only women showed the latter type. Positive anticipation of the stressor predicted stronger cortisol-sAA matched phase coordination for women.

    The relationships of drinking, stress, life satisfaction, coping style, and antidepressant use to mental health were examined in a highly educated workforce. This study used a one-time mail-out, mail-back cross-sectional survey design to examine the relationships of mental health with three kinds of stress (life events, work stress, home stress); two kinds of life satisfaction (work and home); use of avoidance coping; and antidepressant use. This study was conducted at a large worksite in northern California in which the workforce was comprised of predominantly highly educated employees. Questionnaires were mailed to a random sample of 10% of 8567 employees, and 504 were completed and returned by participants (59%). Complete data were provided by 460 participants (53%). Respondents completed the Mental Health Index, the Alcohol Use Disorders Identification Test (AUDIT), and measures of coping style, work and home stress and satisfaction, stressful life events, and antidepressant use. Mean Mental Health Index scores were at the 32nd percentile of the U.S. population-based norms, with low percentile values associated with worse mental health. Using multiple regression analysis, the factors examined in this study were significantly related to Mental Health Index scores as the dependent variable [F(16, 443) = 27.41, p stress at work (p home (p work (p home life (p = .01); engaging in avoidance coping (p stress, home satisfaction and work stress, home satisfaction and avoidance coping, and home satisfaction and use of antidepressants. Mental health status was poorer on average in a highly educated workforce compared with general U.S. norms. Most of the factors that were found to be associated with poorer mental health were ones that are potentially modifiable, such as experiencing more stress and less satisfaction in work and home life and engaging in current hazardous or harmful drinking. The findings that mental health is worse among individual employees who exhibit

    Full Text Available Development of mungbean cultivarstolerant to drought stress through mutation breeding approach would enable us to anticipate the crop yield-reducing effects of climate changes. The objective of this research was to evaluate the yield performance of mungbean mutant lines that showed tolerance to drought stress, and to analyze their genetic diversity and relationship among mutant lines using SSR markers. The study was conducted during the dry season of 2012 in the Muneng experimental farm, Probolinggo, East Java. The experiment was laid out in a randomized block design with four replications. Five mutant lines and two parental lines as control were tested for evaluation of yield and drought tolerance under twoenvironments of two irrigation systems as treatment. The two environmental conditions consisted of optimal irrigation (at least three times: at planting, flowering and during pod filling and suboptimal irrigation (two times at planting and flowering. To evaluate genetic variation among selected mutant lines and their discrimination from parental lines in molecular level, a cluster analysis was performed using Unweighted Pair Group Method with Arithmetic Mean (UPGMA in the NTSYS software. The results showed that three mutant lines, including PsJ30, PsJ31, PsJ32 produced the highest grain yields of 1.17, 1.01, and 1.04 ton/ha, respectively, compared to the other mutant lines and the parents Gelatik (0.85 ton/ha and Perkutut (0.87 ton/ha as control check. Of those mutant lines, PSJ31 was the most tolerant to drought with sensitivity index value of 0.47. The PSJ31 has now been officially released as a new variety ( 2013, named as Muri which was identified to have high yield and tolerant to drought. Based on 23 SSR markers used for clustering analysis of those 3 selected mutant lines,9SSR markers (MBSS R033; satt137; MBSSR008; MBSSR203; MBSSR013; MBSSR021; MBSSR016; MBSSR136; and DMBSSR013 were successfully identified the three mungbean mutant

    To analyze the relationship between memory performance and the neuroendocrine and cardiovascular response to acute psychosocial stress in healthy older people, and the sex and age impact in this relationship. We randomly selected 100 literate older adults, without cognitive or functional impairment. The neuroendocrine stress response was evaluated by measuring the concentration of salivary cortisol, whereas cardiovascular reactions were determined based on blood pressure and heart rate measures taken before, during and after participant exposure to an acute psychosocial stressor (the Trier social stress test [TSST]). Memory performance was evaluated by applying the word pairs test before and after the TSST. A significant reduction in the word pair test scores was observed after the TSST, and a negative correlation between cortisol concentration and immediate and delayed recall of the word pair. Cortisol concentration associated with age, sex and education explained memory performance variability before and after the TSST. The results showed that the influence of acute stress on memory performance during aging might vary according to age and sex, highlighting potential differences in the vulnerability of older individuals to the neurotoxic effects of stress exposure on memory and consequently on the development of cognitive disorders.

    Occupational stress of social workers is associated with various psychosocial hazards in the work environment. Some of them affect person-organization fit (P-O fit). The aim of the study was to verify a hypothesis on the mediating role of P-O fit in the relationship between work environment and stress. The research was based on a sample of 500 social workers directly involved in social work. The data were obtained using the Person-Organization Fit Questionnaire by Czarnota-Bojarska, the Work Environment Questionnaire developed by the Department of Occupational Psychology, Nofer Institute of Occupational Medicine, Łódź, and the Perceived Stress Scale (PSS-10) by Cohen et al. As revealed by the regression analysis of the 4 analyzed work environment factors, only organizational politics was significantly related with perceived stress. Complementary and supplementary dimensions of P-O fit and identification with organization were the mediators of the relationship between organizational policies and stress, but only complementary fit proved to be a total mediator. The results of the study suggest that person-organization fit, especially its complementary aspect, is an essential determinant of accomplishing the core functions of social work and good practice among social workers.

    Sleep is vital for cardiometabolic health, but a societal shift toward poor sleep is a prominent feature of many modern cultures. Concurrently, factors such as diet and lifestyle have also changed and may mediate the relationship between sleep quality and cardiometabolic health. Objectives were to explore (1) the interrelationship and (2) mediating effect of inflammation, oxidative stress, and antioxidants on sleep quality and cardiometabolic health. Cross-sectional data from the US National Health and Nutritional Examination Survey 2005-06 (≥20 y; N = 2,072) was used. Cardiometabolic health was defined as per the Joint Interim Statement; overall sleep quality was determined from six sleep habits and categorized as good, fair, poor, and very poor. Fair quality sleepers had optimal inflammation, oxidative stress, and antioxidant levels. Inflammation was above the current clinical reference range across all sleep quality categories, while oxidative stress was only within the clinical reference range for fair sleep quality. Selected sleep quality-cardiometabolic health relationships were mediated by inflammation, oxidative stress, and antioxidants and were moderated by sex. Our results provide initial evidence of a potential role for inflammation, oxidative stress, and antioxidants in the pathway between poor sleep quality-cardiometabolic decline. Further prospective research is needed to confirm our results.

    There are many mechanisms in which stress can lead to weight gain thus high a BMI. The endocrine and inflammatory pathway can directly increase abdominal adiposity. Another way in which stress leads to weight gain is through changes in health behaviors. The study aimed to investigate the prevalence of musculoskeletal disorders (MSDs) among healthy students of Ahlia University, and to determine the relationship between the development of MSDs and academic stressors and body mass index. Self-administered questionnaires were distributed to 94 students aged 18-26 years who were enrolled at various Ahlia University colleges and met other inclusion criteria. The students responded to the standardized Nordic musculoskeletal questionnaire and the modified College Student Stress Inventory regarding musculoskeletal symptoms and academic stressors. Height and weight measurements were also obtained to determine body mass index. A total of 77.66% reported MSDs in one or more body part, with the prevalence being higher among women than among men. The 7-day prevalence of MSDs severe enough to interfere with activities of daily living was 60.64%, and 44.68% by female and male students, respectively. There was a significant relationship between academic stress and MSDs in the neck, shoulders, lower back, and hips, while the relationship between MSDs, and body mass index, academic stress, and grade point average was not significant. The prevalence of MSDs among Ahlia University students was found to be high. Apart from the positive correlation between academic stress and MSDs in certain body parts, other correlations were not significant.

    Objective: To examine the relationship between recovery experience, occupational stress, and physiological health of nurses in a municipal grade A tertiary hospital. Methods: A total of 296 in-service nurses from 7 municipal grade A tertiary hospitals were selected from October 2015 to February 2016. Individual characteristics of the subjects were collected using a self-made questionnaire. The recovery experience, occupational stress, and physiological health of the subjects were assessed based on the physiological health dimensions in the Chinese version of Recovery Experience Questionnaire (REQ-C) , Job Content Questionnaire (JCQ) , and Quality of Work Life (QWL7-32) . Results: The mean recovery experience score of nurses from the municipal grade A tertiary hospital was 45.04±7.72, and 51.35% of the nurses had satisfactory recovery experience. Occupational stress was identified in 81.76% of the nurses. Based on the four categories of occupational stress, 65 nurses were identified with high-strain jobs (21.95%) , 56 with relaxed (low-strain) jobs (18.92%) , 49 with passive jobs (16.55%) , and 126 with active jobs (42.57%) . In addition, the mean physiological health score of the nurses was 21.20±4.24. Physiological health was negatively correlated with occupational stress ( r =-0.173, P stress ( r =-0.116, P stress, where subjects with high-demand active jobs had the poorest recovery experience ( F =2.610, P stress of nurses, where increased job demand can lead to stronger stress response, reduced recovery experience, and poorer physiological health.

    To evaluate the relationship between the mental stress-induced decrease in left ventricular ejection fraction (LVEF) and the severity of exercise-induced ischaemia, 20 patients with stable coronary artery disease (CAD) underwent radionuclide ventriculography during mental stress testing and stress myocardial perfusion single-photon emission tomography (SPET). We also examined whether changes in haemodynamic and neurohormonal parameters are related to changes in LVEF during mental stress. The LVEF decreased from 54.8%±17.7% to 49.8%±16.2% with mental stress (P<0.0005). Ten of the 20 patients (50.0%) had a ≥5% decrease in LVEF. The remaining ten patients had no or a <5% decrease in LVEF. There was a significant correlation between the change in LVEF during mental stress and the size of the reversible defect on stress myocardial perfusion SPET (r=-0.80, P<0.0005), with close regional correspondence (75% identical). This correlation was less strong in the 12 patients with a total defect score at rest of <10 (r=-0.69, P=0.014) than in the eight patients with a total defect score at rest of ≥10 (r=-0.94, P=0.001). The changes in blood pressure and heart rate were not significantly correlated with the change in LVEF, but the percent change in adrenaline concentration correlated with the change in LVEF. It is suggested that mental stress impairs systolic function by inducing transient myocardial ischaemia. The effect of neurohormonal responses during mental stress on LV systolic function may also be important in patients with CAD. (orig.)

    The purpose of this study was to examine the relationships of personality traits and stress with gingival inflammation and with soft-tissue oral pathology. Personality traits of psychoticism (P), extroversion and introversion (E), and neuroticism (N) were measured with Eysenck's personality questionnaire (EPQ). Stress was measured with a modified organizational and individual assessment survey (OIAS) developed by Hendrix. Military recruits from Ft. Leonard Wood, Missouri, were examined for soft-tissue oral pathology and gingival status at weeks one (n = 241) and six (n = 61) of basic combat training (BCT). The EPQ and OIAS were administered to 217 recruits during week six of BCT. A discriminant analysis was used to determine correlations among study variables. Significant correlations (P personality traits and various measures of tolerance of stress. Little variance was found between groups originally presenting with or without disease.

    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.

    In low- and middle-income countries, a shortage of properly trained, supervised, motivated and equitably distributed health workers often hinder the delivery of lifesaving interventions. Various health workforce bottlenecks can be addressed by tackling well-being and interpersonal relationships of health workers with their colleagues and clients. This paper uses data from the Helping Health Workers Cope (HHWC) project in a rural district of Sierra Leone to achieve three objectives. First, we describe the effect of counseling and psychosocial training on coping skills, stress levels, and provider-provider and provider-client relationships. Second, we examine whether a change in coping skills is associated with a change in relationships. Finally, we qualitatively identify key ways through which the uptake of coping skills is linked to a change in relationships. The HHWC project was implemented from February 2012 to June 2013 in Kono district in the Eastern province of Sierra Leone, with the neighboring district of Tonkolili selected as the control site. The evaluation followed a mixed-methods approach, which included a quantitative survey, in-depth interviews and focus group discussions with health workers and clients. Mean values of the variables of interest were compared across sub-populations, and correlation analyses were performed between changes in coping skills, stress levels, and changes in relationships. Overall, the results demonstrate that the HHWC intervention had a positive effect on coping skills, stress levels and provider-provider and provider-client relationships. Furthermore, associations were observed between changes in coping skills and changes in relationships as well as changes in stress management skills and changes in relationships. Psychosocial education can have major impacts on health worker well-being and the quality of health care delivery.

    On the basis of mechanical tests and metallographic studies, strainrange partitioned lives were predicted by introducing stress-strain materials parameters into the Universal Slopes Equation. This was the result of correlating fatigue damage mechanisms and deformation mechanisms operating at elevated temperatures on the basis of observed mechanical and microstructural behavior. Correlation between high temperature fatigue and stress strain properties for nickel base superalloys and stainless steel substantiated the method. Parameters which must be evaluated for PP- and CC- life are the maximum stress achievable under entirely plastic and creep conditions respectively and corresponding inelastic strains, and the two more pairs of stress strain parameters must be ascertained.

    In the present study, witnessing in-home violence and peer relationship quality are evaluated as to their relative impact on Post Traumatic Stress (PTS) symptoms among children aged 8 to 17 investigated by child protective services (CPS) for maltreatment exposure. The sample included 2151 children from the National Survey of Child and Adolescent Well-Being II (NSCAW II). Linear growth models were estimated to assess associations between changes in PTS symptoms, witnessing in-home violence, and peer relationship quality over time. Greater frequency of witnessing in-home violence at baseline (i.e. wave 1) was associated with higher baseline PTS symptoms (β = 0.44). Increases in witnessing in-home violence frequency over time (average annual change across three years) had a strong association with increases in PTS symptoms over time (β = 0.88). Baseline peer relationship quality was associated with fewer PTS symptoms at baseline (β = -0.45). Increases in peer relationship quality over time were strongly associated with declines in PTS symptoms over time (β = -0.68). Peer relationship quality at baseline did not moderate baseline or over time associations between witnessing in-home violence and PTS symptoms. The average decline in PTS symptoms due to decreases in witnessing in-home violence and increases in peer relationship quality was 0.51 and 0.65 standard deviations respectively, over the three-year study period. Reducing chronic witnessing in-home violence and promoting the development of healthy social relationships with peers are critical for PTS symptom recovery. Copyright © 2018 Elsevier Ltd.

    The aim of this study was to examine the relationship between menses-associated health problems of women, such as premenstrual symptoms, menstrual pain and irregular menstrual cycles, and psychosocial stress. A cross-sectional study was conducted among Japanese college students, measuring psychosocial stress levels by means of IMPS (The Inventory to Measure Psychosocial Stress). A total of 264 female students (mean age 19.4 years), who were invited to participate in the study in October 2007, completed the questionnaire, which dealt with anthropometric data, lifestyle, menstrual history, and menstrual health status. Forty-three students were excluded due to missing data, and the remaining 221 were analyzed. The proportions of students who reported premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles were 79%, 79%, and 63%, respectively. Students who reported premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles had higher stress scores than those who did not. Multiple logistic regression analyses were used to identify independent factors associated with having premenstrual symptoms, menstrual pain, and the experience of irregular menstrual cycles. Stress score, heavy menstrual flow, and menstrual pain were significant predictors for premenstrual symptoms, while age at menarche and having premenstrual symptoms were significant predictors for menstrual pain. Both stress score and body mass index were found to be significant predictors for having experienced irregular menstrual cycles. The results suggest that psychosocial stress is independently associated with premenstrual symptoms and the experience of irregular menstrual cycles among college students, implying that changes in the functional potentiality of women as a result of stress are related with changes in their menstrual function.

    The development of borderline personality disorder (BPD) has been associated with parenting styles and parental psychopathology. Only a few studies have examined current parental rearing styles and parental psychopathology in relationship to BPD symptoms in adolescents. Moreover, parenting stress has not been examined in this group. The current study examined 101 adolescents (14-19 years old) with BPD symptoms and their mothers. Assessments were made on severity of BPD symptoms, youth-perceived maternal rearing styles, and psychopathology and parenting stress in mothers. Multiple regression analyses were used to examine potential predictors of borderline severity. No correlation was found between severity of BPD symptoms in adolescents and parenting stress. Only youth-perceived maternal overprotection was significantly related to BPD severity. The combination of perceived maternal rejection with cluster B traits in mothers was significantly related to BPD severity in adolescents. This study provides a contribution to the disentanglement of the developmental pathways that lead to BPD.

    To examine the relationship of self-reported parental overprotection, perceived child vulnerability, and parenting stress to parent-reported behavioral, emotional, and social adjustment of children currently on treatment for cancer. Parents of 62 children (34 boys, 28 girls) currently on treatment for cancer were recruited from an outpatient pediatric cancer clinic. Children ranged in age from 2 to 12 years; age at diagnosis ranged from 1.33 to 11.83 years. Higher levels of parenting stress, but not parental overprotection or perceived child vulnerability, were associated with poorer behavioral and social adjustment. Higher levels of perceived child vulnerability and parenting stress, but not parental overprotection, were independently associated with poorer emotional adjustment. Specific parenting variables appear to be related to specific adjustment outcomes in children with cancer. Longitudinal follow-up of these children is necessary to determine the developmental trajectory of parent variables and long-term child outcomes.

    Job characteristics and the consequences of everyday stress among radio journalists who are not exposed to traumatic events have not been studied sufficiently before. We aimed at determining the most common job characteristics and their stressfulness; relationships between stress exposure, health and occupational functioning; differences between radio journalists and other journalists, and also the psychosocial risk for health and functioning in this group. The studied group involved 208 journalists, 134 of whom worked in radio stations. The respondents filled in the Psychosocial Risks Scale (PRS) developed by the Department of Health and Work Psychology of the Nofer Institute of Occupational Medicine, Łódź, Poland. Requirement of mental effort and readiness to response quickly for most of the time as well as limited possibilities for promotion were the most frequent journalists' complaints. We confirmed that higher levels of stress resulted in worse functioning--the radio journalists who experienced lower stress assessed their health status and ability to work better, were more satisfied with particular aspects of their work, and were more involved in their work. They also presented a significantly lower turnover intention. Moreover, the radio journalists were more involved in their work than other journalists, but experienced lower satisfaction, took more sick leaves and had more days of absence. Well-known relationships between stress level, satisfaction and occupational functioning were confirmed. The most important conclusion refers to the fact that psychosocial risks and stress analysis should be based on the understanding of specificity of each occupation or even position. It is so, because the same job characteristic may pose a challenge for one person, while for another--it can result in extreme discomfort and anxiety--such an attitude broadens understanding of the phenomenon. We also confirmed that the PRS is a well-designed method, appropriate to

    Full Text Available Aim: Students are subjected to different kinds of stressors, such as the pressure of academics with an obligation, an uncertain future and difficulties of integrating into the system. Although nursing and midwifery students experience a high level of stress during their training, there has been limited research on stress and its impact on the student's physical responses, such as gastrointestinal symptoms. The aims of this study are to assess the prevalence of gastrointestinal symptoms in nursing and midwifery students and to examine the association between the perceived stress and gastrointestinal symptoms. Methods: This performed using cross-sectional descriptive study design study enrolled a total of 449 students participates in the study in a university degree program was carried out on 366 nursing and midwifery students accepted. A personal information questionnaire, Perceived Stress Scale and a Gastrointestinal Symptoms Questionnaire were administered through a self-reported system. Results: Seventy point two percent of the nursing and midwifery students experienced at least one gastrointestinal symptom, with 35.8% of students reporting at least three gastrointestinal symptoms. Most of the nursing and midwifery students complained of upper dysmotility and bowel symptoms. In addition, students who reported higher perceived stress were significantly more likely to complain of gastrointestinal symptoms. Compared to students with the lowest perceived stress level, the adjusted odds ratio for gastrointestinal symptoms in students with the highest perceived stress level was 6.45 times higher. Conclusions: Gastrointestinal symptoms that are highly prevalent among nursing and midwifery students are significantly associated with the perceived stress level. High perceived stress should be considered a risk factor for gastrointestinal symptoms. Based on the study findings, there is a critical need of instructing the nursing and midwifery students

    Youth suicide is increasingly being recognized as a major social problem in South Korea. In this study, we aimed to explore the effects of parental support on the relationship between life stress and suicidal ideation among middle-school students. This study analyzed data from a cross-sectional study on mental health conducted by the South Korea National Youth Policy Institute between May and July of 2013. Questionnaire responses from 3,007 middle-school students regarding stress factors, thoughts of suicide during the past year, and parental support were analyzed in terms of 3 subscale elements: emotional, academic, and financial support. Among the participants, 234 male students (7.8%) and 476 female students (15.8%) reported experiencing suicidal ideation in the past year. Life stress significantly influenced suicidal ideation (Pstress increased suicidal ideation (adjusted odds ratio [aOR], 1.318; Pstress on suicidal ideation decreased with parental support (aOR, 1.238; Pstress was independently related to an increase in suicidal ideation. Parental support buffered the relationship between life stress and suicidal ideation.

    Numerous studies conducted within the USA demonstrate higher levels of benefit finding in ethnic minority individuals compared to nonminority individuals living with chronic disease. As benefit finding may be a salient buffer for the effects of stress, the current study examined the association between perceived stress and benefit finding in human immunodeficiency virus (HIV)+ men who have sex with men (MSM) living in the southeast USA and investigated whether ethnicity was a moderator of this relationship. We hypothesized that benefit finding would be greater in ethnic minority MSM than in white MSM and that ethnic minority MSM with high levels of stress would experience greater benefit finding than their white MSM counterparts. The current study utilized baseline (T1) and 3-month follow-up (T2) data drawn from a previous trial of a psychosocial intervention in HIV+ MSM. Participants were 130 HIV+ MSM; 52 % were white and 48 % belonged to minority ethnic groups (African-American, Caribbean-American, Hispanic). Analyses revealed that benefit finding was greater in ethnic minority MSM at baseline; however, this difference became nonsignificant when age, education level, highly active antiretroviral therapy adherence, and CD4 count were added to the model. Moderated regression analyses revealed a significant interaction between T1 perceived stress and ethnicity in predicting T2 benefit finding, such that higher levels of T1 perceived stress predicted lower levels of T2 benefit finding in ethnic minority MSM only. This association was independent of intervention group assignment. The current study's results highlight potential differences in the relationship between stress and benefit finding processes in white and ethnic minority HIV+ MSM.

    Mercury (Hg) is a global pollutant that is released into the environment from geologic and anthropogenic sources. Once it enters an organism, it generates several toxicity mechanisms and oxidative stress has been proposed as the main one. Metal susceptibility is greater in children, which is a result of their physiology and behavior. In Yucatan, Mexico, burning of unregulated garbage dumps and household trash, ingestion of top marine predators, and pottery manufacturing are among the conditions that could promote Hg exposure. However, for Yucatan, there are no published studies that report Hg levels and associated oxidative stress status in children. Therefore, this study aimed to assess Hg levels in blood and urine and oxidative stress biomarkers levels in a sample of 107 healthy children from three localities in Yucatan, Mexico, as well as investigate the relationship between these parameters. Hg was detected in 11 (10.28%) of blood samples and 38 (35.51%) of urine samples collected from the participating children. Fourteen subjects showed Hg above recommended levels. The oxidative stress biomarkers were slightly elevated in comparison with other studies and were statistically different between the sampling sites. No linear correlation between Hg levels and oxidative stress biomarkers was found. Nevertheless, exploratory univariate and multivariate analysis showed non-linear relations among the measured variables. Globally, the study provides, for the first time, information regarding Hg levels and their relationship with oxidative stress biomarkers in a juvenile population from Mexico's southeast (Yucatan) region. In agreement with worldwide concern about Hg, this study should stimulate studies on metal monitoring in humans (especially children) among scientists working in Mexico, the establishment of polices for its regulation, and the reduction of human health risks.

    The purpose of this study was to explore potential mediators of the relationship between depression and obesity in a sample of low-income, minority women. Data were extracted from a sample of 535 women enrolled in a weight loss intervention for the prevention of type 2 diabetes. Using a non-parametric bootstrapping procedure, the potential mediation effects of stress eating and sleep disturbance on the relationship between depression and obesity were tested. Results of a single mediation model indicated that depressive symptomatology was significantly associated with obesity (β=0.800, SE=0.290, p=0.006), and that stress eating (β=0.166, 95% CI [0.046, 0.328]) and sleep disturbance (β=1.032, 95% CI [0.612, 1.427]) were significant independent mediators of this relationship. Sleep disturbance remained a significant mediator in a combined mediation model (β=1.009, 95% CI [0.653, 1.399]). Findings add to the growing literature on the psychosocial factors implicated in the link between depression and obesity, particularly among disadvantaged populations. Future longitudinal research should aim to establish causal pathways between obesity, stress eating, sleep disturbance, and depression.

    This study examined the hypotheses that contingent self-esteem would be positively associated with alcohol-related problems and that global self-esteem would be negatively associated with such problems. It also examined the hypothesis that high stress and maladaptive coping would mediate these relationships. A sample of college students (n = 399) who were predominantly Hispanic (89%) completed measures of global and contingent self-esteem; stress and coping; and alcohol-related problems. Correlational and latent variable analyses indicated that contingent self-esteem positively related to alcohol-related problems, with maladaptive coping mediating this relationship. In contrast, global self-esteem negatively related to such problems, a relationship that was also mediated by maladaptive coping and stress. Overall, the results highlight the potentially harmful consequences of contingent self-worth and the adaptive nature of non-contingent self-esteem. They also demonstrate the important role that coping plays in mediating self-esteem's associations with alcohol-related problems. Copyright © 2012 John Wiley & Sons, Ltd.

    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.

    Psychiatric nursing is a stressful area of nursing practice. The purpose of this study was to examine occupational stress among psychiatric nurses in Japan. In this cross-sectional study, 238 psychiatric nurses were recruited from 7 hospitals. Data regarding the Generic Job Stress Questionnaire (GJSQ), the Center for Epidemiologic Studies for Depression Scale (CES-D), and the Health Practice Index (HPI) were obtained via self-report questionnaires. After adjusting for all the variables, CES-D scores were associated with job stress, but social support reduced the effect of stress on depression among psychiatric nurses. However, the interpretation of these results was hampered by the lack of data concerning important occupational factors, such as working position, personal income, and working hours. Further longitudinal investigation into the factors associated with depression may yield useful information for administrative and psychological interventions.

    The objective of this study was to test the direct and moderating effects of different coping styles in mitigating perceived stress associated with antenatal anxiety symptoms among 755 pregnant women in Chengdu. A cross-sectional study using a questionnaire survey was carried out. The Perceived Stress Scale, the Trait Coping Style Questionnaire and the Zung Self-rating Anxiety Scale were used to measure stress, coping and anxiety symptoms, respectively. Hierarchical regression analysis was used to test the direct and moderating effects of coping styles in the relationship between perceived stress and antenatal anxiety symptoms. Direct effects of negative coping (NC) styles were found. Women with higher NC scores were more likely to have anxiety symptoms. Positive coping (PC) styles had moderating effects on perceived stress, whereas NC styles did not. The findings of this study highlight the direct and moderating effects of coping styles. This knowledge is important to healthcare professionals in planning health service provision. Health services should dedicate resources to teaching pregnant women how to enhance PC styles, alter NC styles and cultivate optimistic thinking to alleviate anxiety symptoms.

    We investigated the relationships between stress, learning strategies, and study success among first-year veterinary students at the very beginning of their veterinary studies. The study was carried out during the first course on macroscopic anatomy (osteology), which students have in the past found to be exceptionally stressful. Students (N=45) completed a questionnaire concerning their self-reported views on stress and learning strategies, which were compared with their self-reported written-test scores. Participants who had previously gained university credits did not have significantly better test scores, but they achieved the learning goals with significantly less stress than other participants. Previous experience of university study helped students not only to adjust to a new type of course content and to achieve the learning goal of the osteology course, but also to cope with the stress experienced from taking concurrently running courses. Of the respondents who specifically named factors relating to self-regulation and modification of their learning strategy, all had gained prior credits. These students were able to use their study time efficiently and adjust their schedules according to the course demands.

    Parent and teacher ratings of child behaviors are often discrepant, and these discrepancies may be correlated with parenting stress. The present study explored whether various parenting stress factors are associated with discrepancies between parent and teacher ratings of attention-deficit/hyperactivity disorder and oppositional defiant disorder (ODD) as well as internalizing symptoms in preschool children. We recruited 299 Taiwanese preschool children (aged 4–6 years) from the community or via clinical referrals. A structural equation modeling was used to analyze the relationships among three factors derived from the Parenting Stress Index-Short Form and informant discrepancies on symptoms of inattention, hyperactivity/impulsivity, ODD, and internalizing behaviors. Scores reported by parents were higher for each of the symptoms examined than those reported by teachers, and the degree of agreement between informants ranged from low to moderate. The parental distress factor of parenting stress was associated only with parent ratings, whereas other factors of parenting stress—parent-child dysfunctional interaction and parents’ stress resulted from their child’s temperament—were correlated with both parent and teacher ratings. Only parental distress factor predicted informant discrepancies for all behavioral symptoms assessed. Our findings suggest that parental distress should be considered when parent rating scores show significant discrepancies from that of teacher rating scores. PMID:29016602

    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.

    Systemic hypertension confers a hypercoagulable state. We hypothesized that resting mean blood pressure (MBP) interacts with stress hormones in predicting coagulation activity at rest and with acute mental stress. We measured plasma clotting factor VII activity (FVII:C), FVIII:C, fibrinogen, D-dimer, epinephrine and norepinephrine, and saliva cortisol in 42 otherwise healthy normotensive and hypertensive medication-free men (mean age 43 +/- 14 years) at rest, immediately after stress, and twice during 60 min of recovery from stress. At rest, the MBP-by-epinephrine interaction predicted FVII:C (beta = -0.33, P AUC) predicted D-dimer AUC (beta = 0.34, P = 0.04) independent of MBP. The MBP-by-epinephrine AUC interaction predicted FVII:C AUC (beta = 0.28) and fibrinogen AUC (beta = -0.30), and the MBP-by-norepinephrine AUC interaction predicted FVIII:C AUC (beta = -0.28), all with borderline significance (Ps < 0.09) and independent of age and BMI. MBP significantly altered the association between stress hormones and coagulation activity at rest and, with borderline significance, across the entire stress and recovery interval. Independent of MBP, catecholamines were associated with procoagulant effects and cortisol reactivity dampened the acute procoagulant stress response.

    Personality traits have often been highlighted to relate to how people cope with stressful events. The present paper focuses on character strengths as positive personality traits and examines two basic assumptions that were derived from a core characteristic of character strengths (i.e., to determine how individuals deal with adversities): (1) character strengths correlate with coping and (2) buffer the effects of work-related stress on job satisfaction. Two different samples (i.e., a mixed sample representing various occupations [N = 214] and a nurses sample [N = 175]) filled in measures for character strengths, coping, work-related stress, and job satisfaction. As expected, intellectual, emotional, and interpersonal strengths were related to coping. Interpersonal strengths played a greater role for coping among nurses, as interactions with others are an essential part of their workday. Furthermore, intellectual strengths partially mediated the negative effect of work-related stress on job satisfaction. These findings open a new field for research on the role of personality in coping with work-related stress. Character strengths are trainable personal characteristics, and therefore valuable resources to improve coping with work-related stress and to decrease the negative effects of stress. Further research is needed to investigate this assumed causality.

    This aimed to assess the potential role of chronic stress in saliva secretion, xerostomia, and oral health in a population attending a saliva clinic. Data of 114 patients who met the inclusion criteria and completed all questionnaires were analyzed in this study. Participants completed several validated questionnaires, including the Perceived Stress Scale, the Oral Health Impact Profile (OHIP-14), Xerostomia Inventory (XI), and Bother xerostomia Index (BI). Subsequently, the unstimulated, chewing-stimulated, and citric acid-stimulated saliva secretion rates were determined gravimetrically. Data were evaluated using Spearman's correlation analysis and the Mann-Whitney U test. A significant correlation was observed between perceived stress and XI score (r = 0.312, p = 0.001), as well as between perceived stress and BI score (r = 0.334, p = 0.001). Stress levels also were significantly associated with OHIP-14 scores (r = 0.420, p stress and salivary flow rate could not be established. In this population, perceived chronic stress seems to be related to several aspects of dry mouth, including the perception of dry mouth, suffering from dry mouth, and the impact on quality of life. These effects were independent of the use of psychotropic medication. No actual reduction in salivary flow was found. Further studies to explore the causal linkage of stress with xerostomia seem warranted. Perceived chronic stress seems to be related with several aspects of dry mouth. This finding might be relevant in future prevention and treatment of xerostomia.

    Teaching has been reported to be one of the most stressful occupations in the world. Few studies have been conducted to explore the effects of occupational stress on burnout among teachers in developing countries. This study aimed to explore the relationship between occupational stress and burnout among teachers in primary and secondary schools in the Liaoning Province of China. A questionnaire that assessed occupational stress comprised of Karasek's job content questionnaire (JCQ), Siegrist's effort-reward imbalance questionnaire (ERI), and burnout assessed by the Maslach Burnout Inventory-General Survey was distributed to 681 teachers in primary and secondary schools. A total of 559 effective respondents became our final study subjects. Hierarchical linear regression and logistic regression analyses were performed through the use of SPSS 17.0 to explore the association between occupational stress and burnout. A high level of emotional exhaustion was significantly associated with high extrinsic effort, high overcommitment, low skill discretion, and high job demand. A high level of cynicism was associated with low reward, low skill discretion, high overcommitment, and low supervisor support. The low level of professional efficacy was associated with low coworker support, low reward, low skill discretion, and high job demand. Compared to the JCQ, the ERI was more likely to explain the burnout of teachers in our study. Occupational stress proved to be associated with dimensions of burnout among Chinese teachers. It is important for administrators of primary and middle schools to note that strategies to decrease teachers' occupational stress seem to be crucial to enhance physical and mental health of teachers in China.

    Stress is a well-known risk factor for psychopathology and rodent models of social defeat have strong face, etiological, construct and predictive validity for these conditions. Syrian hamsters are highly aggressive and territorial, but after an acute social defeat experience they become submissive and no longer defend their home territory, even from a smaller, non-aggressive intruder. This defeat-induced change in social behavior is called conditioned defeat (CD). We have shown that dominant hamsters show increased neural activity in the ventromedial prefrontal cortex (vmPFC) following social defeat stress and exhibit a reduced CD response at social interaction testing compared to subordinates. Although the vmPFC can inhibit the neuroendocrine stress response, it is unknown whether dominants and subordinates differ in stress-induced activity of the extended hypothalamic-pituitary-adrenal (HPA) axis. Here, we show that, following acute social defeat, dominants exhibit decreased submissive and defensive behavior compared to subordinates but do not differ from subordinates or social status controls (SSCs) in defeat-induced cortisol concentrations. Furthermore, both dominants and SSCs show greater corticotropin-releasing hormone (CRH) mRNA expression in the basolateral/central amygdala compared to subordinates, while there was no effect of social status on CRH mRNA expression in the paraventricular nucleus of the hypothalamus or bed nucleus of the stria terminalis. Overall, status-dependent differences in the CD response do not appear linked to changes in stress-induced cortisol concentrations or CRH gene expression, which is consistent with the view that stress resilience is not a lack of a physiological stress response but the addition of stress coping mechanisms. Lay summary Dominant hamsters show resistance to the behavioral effects of acute social defeat compared to subordinates, but it is unclear whether social status modulates the neuroendocrine stress response

    Background: High levels of both prolonged grief symptoms (PGS) and posttraumatic stress symptoms (PTSS) are relatively common following bereavement, and the two types of bereavement complications share some of the same features. Little research has studied which of the two precedes the other...... following the death of a loved one. The purpose of this study was to examine the temporal relationship between change in high levels of PGS and PTSS during the first four years following old age spousal loss. Methods: Participants were 237 Danes (40% male; mean age = 73 years, SD = 4.4; range 65-81) who....... Results: Lower-level mediation analyses wereas performed. Results indicated that PGS mediated 83% of the relationship between time and PTSS, while PTSS only mediated 17% of the relationship between time and PGS. These results suggest that changes in PGS mediated changes in PTSS following spousal...

    Post-traumatic stress disorder (PTSD) is a major health concern among the U.S. military population, affecting up to 12% to 24% of veterans returning from Iraq and Afghanistan. Sleep disturbances, neuroticism, and childhood trauma have all been associated with the development of PTSD in military populations, especially in relation to combat experiences. The effects of disrupted sleep and post-traumatic stress can affect the physical well-being of soldier and sailors in the field and impact them for years after deployment. This study aimed to evaluate the relationship between self-reported measures of combat experiences, PTSD symptoms, sleep, neuroticism, and childhood adversity in an active duty military population. 972 U.S. Navy Sailors serving in Afghanistan were given anonymous surveys that assess scales of combat stressors, PTSD symptoms, sleep problems, neuroticism, adverse child experiences (ACEs), and other covariates. Sleep disturbances were hypothesized as moderators, having an indirect effect on the relationship between combat experiences and PTSD symptoms. Neuroticism scores and ACEs were proposed as moderators of the combat-PTSD symptom relationship. Mediation and moderation models were developed and tested using logistic regressions. Increased number of combat experiences was found to be a significant predictor of PTSD, even when adjusting for all covariates (p moderating factor. These results indicate that the presence of nightmares may partially explain how traumatic combat experiences lead to the development of PTSD. The study also reaffirms neuroticism as risk factor for developing PTSD symptoms. These findings highlight the importance of sleep hygiene and operational stress models in combat situations and may help stress control professionals address risk factors associated with PTSD symptoms.

    It is generally believed that the failure of TBCs is attributed to the spallation occurred in the ceramic coat. The spallation is closed linked with sinuate morphology factors, including its amplitude and period, at the TGO/bond coat interface. In this work, dependence of the residual stress distribution on the sinuate morphology in the TBCs has been studied by means of finite element method (FEM) simulation for isothermally annealed specimens. The simulation results indicated that the maximum value of residual stress existed inside the TGO layer. It was also found that the maximum residual stress occurred at different points, near the TGO/bond coat interface at the peak of the sinuate interface, while near the TGO/ceramic coat interface at the valley, respectively. And the maximum residual stress increased with increasing the ratio of the amplitude to period in the sine morphology, which has been proved by the thermal cycle experimental results. (orig.)

    The aim of this study was to evaluate the predictive effects of infertility-related stress on psychological distress and marital satisfaction. Structural equation modeling was used to estimate a nonrecursive model hypothesizing the impact of infertility-related stress on both emotional distress and marital dissatisfaction, which were supposed to have a reciprocal influence on each other. The model was estimated using data from a sample of 150 infertile patients (78 males and 72 females). Findings confirmed the predictive effects of infertility-related stress on both emotional and marital distress. However, infertility-related stress was found to have more impact on emotional distress than on marital satisfaction. © The Author(s) 2014.

    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 aim was to assess subjective oral health symptoms and job stress, as measured by self-assessment of how demanding the job is, in male financial workers. The participants were recruited by applying screening procedures to a pool of Japanese registrants in an online database. For the stress check, 7 items about how demanding the job is were selected from The Brief Job Stress Questionnaire (BJSQ). Participants comprised a total of 950 financial male workers, ages 25 to 64. Participants who answered "I can't complete my work in the required time" had more decayed teeth (p=0.010). Participants who felt that their job is highly demanding (answered affirmatively to 6 or all 7 items) were more likely to report "often get food stuck between teeth" (p=0.030), "there are some foods I can't eat" (p=0.005), "bad breath" (p=0.032), and "jaw makes clicking sound" (p=0.032). The independent variable of total stress score of 24-28 was found to be correlated to at least three oral health symptoms (OR: 3.25; 95%CI: 1.66-6.35). These results indicate that certain job stress factors are associated with certain oral health symptoms, and that oral health symptoms are likely predictors of job stress.

    This study investigates the parental perception of stress related to the upbringing of children with CHARGE syndrome and its association with behavioral and physical child characteristics. Parents of 22 children completed the Nijmegen Parenting Stress Index-Short, Developmental Behavior Checklist, and Dutch Vineland Screener 0-12 and reported their child's problems with hearing, vision and ability to speak. Parenting stress was high in 59% of the subjects. Behavioral problems on the depression, autism, self-absorbed and disruptive behavior scales correlated positively with parenting stress. A non-significant trend was found, namely higher stress among the parents of non-speaking children. No associations were found with other child characteristics, i.e. level of adaptive functioning and intellectual disability, auditory and visual problems, deafblindness, gender, and age. Raising a child with CHARGE syndrome is stressful; professional support is therefore essential for this population. More research into other possible influencing characteristics is needed to improve family-oriented interventions. Since CHARGE is a rare syndrome, closer international collaboration is needed, not only to expand the group of study subjects to increase statistical power, but also to harmonize research designs and measurement methods to improve the validity, the reliability, and the generalization of the findings.

    Full Text Available This study analyses the role played by daily stress, assessed through self-report and at the psychobiological level, in relation to basic cognitive function when predicting school performance. The sample comprised 100 schoolchildren (55 girls and 45 boys, age range 8 to 11 years from a state school in the city of Malaga (Spain. Daily stress was assessed through the Children's Daily Stress Inventory (IIEC m Spanish; Tnanes et al., 2009. Psychobiological stress was measured through the cortisol/DHEAS ratio, derived from saliva samples taken in the morning on two consecutive days. Basic cognitive skills were assessed by means of the Computerized Cognitive Assessment System (CDR battery; Wesnes et al., 2003, 2000. Finally, the measure of school performance was the mean value of the final grades recorded in the child's school report. In addition to descriptive and correlational statistical analyses, multiple regression analyses were conducted in order to assess the model. The results show that children's daily stress self-reported contributes to predict school performance, and has proven to be more influential than basic cognitive function when it comes to predict school performance. Therefore, in order to achieve good school performance, a pupil not only requires good basic cognitive function, but must also present low levels of self-reported daily stress. These findings suggest a new way of e
