    Full Text Available En este trabajo se busco conocer si existen diferencias en el locus de control según el nivel de pobreza en una población de 900 personas clasificadas en tres grupos: pobres extremos, pobres moderados y no pobres. Los sujetos estudiados compartieron la característica de ser personas económicamente independientes. Para este estudio se utilizaron como instrumentos de medición, un cuestionario sociodemográfico y una escala de locus de control. Los resultados muestran que los grupos de mayor ingreso familiar así como el grupo de no pobres y el de pobres moderados presentan en mayor medida un locus de control interno, mientras que el grupo de pobres extremos un mayor locus de control externo; por otro lado se observó que las personas de sexo masculino así como los de más edad (36 a 72 años presentan un locus de control más interno que aquellas personas de sexo femenino y de menor edad (19 a 35 años. Además, las personas con mayor nivel educativo (licenciatura y postgrado presentan una mayor tendencia hacia la internalidad en comparación con las personas de menor nivel educativo (sin escolaridad, primaria, secundaria y preparatoria. A su vez, se observó que la escolaridad de los padres influye en el locus de control.

    Full Text Available In the developed world, the hazards associated with obesity have largely outstripped the risk of starvation. Obesity remains a difficult public health issue to address, due in large part to the many disciplines involved. A full understanding requires knowledge in the fields of genetics, endocrinology, psychology, sociology, economics, and public policy – among others. In this short review, which serves as an introduction to the Frontiers in Endocrinology research topic, we address one cross-disciplinary relationship: the interaction between the hunger/satiation neural circuitry, an individual’s perceived locus of control, and the risk for obesity. Mammals have evolved a complex system for modulating energy intake. Overlaid on this, in humans, there exists a wide variation in perceived locus of control – that is, the extent to which an individual believes to be in charge of the events that affect them. Whether one has primarily an internal or external locus of control itself affects, and is affected by, external and physiological factors and has been correlated with the risk for obesity. Thus, the path from hunger and satiation to an individual’s actual behavior may often be moderated by psychological factors, included among which is locus of control.

  7. A single base difference between Pit-1 binding sites at the hGH promoter and locus control region specifies distinct Pit-1 conformations and functions.

    Activation of the human growth hormone (hGH-N) gene in pituitary somatotropes is mediated by a locus control region (LCR). This LCR is composed of DNase I-hypersensitive sites (HS) located -14.5 kb to -32 kb relative to the hGH-N promoter. HSI, at -14.5 kb, is the dominant determinant of hGH-N expression and is essential for establishment of a 32-kb domain of histone acetylation that encompasses the active hGH locus. This activity is conferred by three binding sites for the POU domain transcription factor Pit-1. These Pit-1 elements are sufficient to activate hGH-N expression in the mouse pituitary. In contrast, Pit-1 sites at the hGH-N promoter are consistently unable to mediate similar activity. In the present study, we demonstrate that the functional difference between the promoter-proximal and the HSI Pit-1 binding sites can be attributed in part to a single base difference. This base affects the conformation of the Pit-1/DNA complex, and reciprocal exchange of the divergent bases between the two sets of Pit-1 elements results in a partial reversal of their transgenic activities. These data support a model in which the Pit-1 binding sites in the hGH LCR allosterically program the bound Pit-1 complex for chromatin activating functions.

    1979-12-01

    Reviews findings on the relationships between locus of control and anxiety and examines these relationships for three types of anxiety measures; general trait anxiety, situation specific trait anxiety, and state anxiety. In general, findings support the existence of meaningful relationships between greater externality and higher levels of both general trait anxiety and test anxiety. It was suggested that the relation between locus of control and state anxiety is a function of the situational context in which state anxiety is measured.

    The diversity of sickle cell disease severity is attributed to several cis acting factors, among them the single nucleotide polymorphisms (SNPs) and (AT) rich region in the β-locus control region (β-LCR). This contains five DNase I hypersensitive sites (HS) located 6 to 22 kb upstream to the ϵ gene. The most important of these is the HS2 (5' β-LCR-HS2), characterized by the presence of three different SNPs and a microsatellite region known to be in association with β(S) chromosomes in various populations. The aim of this study was to present the molecular investigation of the 5' β-LCR-HS2 site in normal and sickle cell disease individuals in order to determine if there is any correlation or specificity between these molecular markers, the β(S) Tunisian chromosomes and phenotypical expression of sickle cell disease. One hundred and twenty-four chromosomes from Tunisian individuals (49 β(S) carriers and 13 normal individuals) were screened by polymerase chain reaction (PCR) and sequencing for the polymorphic short tandem microsatellite repeats (AT)(X)N(12)(AT)(Y) and the three SNPs (rs7119428, rs9736333 and rs60240093) of the 5' β-LCR-HS2. Twelve configurations of the microsatellite motif were found with an ancestral configuration elaborated by ClustalW software. Normal and mutated alleles were observed at the homozygous and heterozygous states for the three SNPs. Correlation between microsatellites and SNPs suggests that mutant SNP alleles were mainly associated, in the homozygous sickle cell disease phenotype, with the (AT)(8)N(12)GT(AT)(7) configuration, whereas, normal SNP alleles were associated with the (AT)(X)N(12)(AT)(11) configurations in normal β(A) chromosomes. The correlation of these various configurations with Hb F expression was also investigated. The principal component analysis (PCA) showed the correlation between the homozygous sickle cell disease phenotype, mutated SNP alleles and the Benin microsatellite configuration (AT)(8)N(12)GT

    Full Text Available The integration of online learning in university courses is considered to be both inevitable and necessary. Thus there is an increasing need to raise awareness among educators and course designers about the critical issues impacting on online learning. The aim of this study, therefore, was to assess the differences between two groups of first-year Business Sciences learners (online and conventional learners in terms of biographic and demographic characteristics and locus of control. The study population consisted of 586 first-year learners of whom 185 completed the Locus of Control Inventory (LCI. The results show that the two groups of learners do not differ statistically significantly from each other with respect to locus of control. The findings and their implications are also discussed. Opsomming Die integrasie van aanlyn-leer in universiteitskursusse word beskou as sowel onafwendbaar as noodsaaklik.

Respecto de los primeros, se ha indagado acerca de las atribuciones que se realizaban en torno a las recompensas y sanciones, que ellos distribuían a sus alumnos. Respecto de los segundos, se ha buscado determinar la valoración que estos realizaban de sus profesores, en términos de aquellas atribuciones. Para ello, se utilizaron dos paradigmas clásicamente empleados para verificar la existencia de una norma: el paradigma de la autopresentación (docentes, y el paradigma de los juicios (alumnos. La cuestión planteada fue determinar si en el caso de los comportamientos distributivos de refuerzos, las causas se atribuían a variables externas -en particular a los receptores de esos refuerzos- y si esas formas de atribución eran conocidas y valoradas o no, por los alumnos. De los resultados, surgió la confirmación de nuestra hipótesis de explicaciones externas en materia de comportamientos distributivos de sanciones en el ámbito de la docencia y la valoración positiva de estas atribuciones por los alumnos.

    This article examined how individuals' locus of control might moderate the effect of health message frames. An experiment was conducted whereby participants read either individual- or social-responsibility message frames after their locus of control was primed. Results indicated that messages presented in individual-responsibility frames were more persuasive when people were primed with internal locus of control, whereas social-responsibility framed appeals were more persuasive when people were primed with external locus of control. These results were found for individuals in both high and low cognitive load conditions. Theoretical and practical implications of the findings are discussed.

    Examined relationships between the Multidimensional Health Locus of Control (MHLC) Scales, Beck Depression Inventory, Trait subscales of the State-Trait Personality Inventory, and dental ratings of oral hygiene and presence of periodontal disease with dental outpatients (N = 101) at a Veterans Administration Medical Center Dental Clinic. Results indicated that this sample of outpatients scored comparably on MHLC Health Internality and Health Externality to a sample reported by Wallston and Wallston. Older dental patients, in the present sample, scored significantly higher on Powerful Others Externality in contrast to younger Ss, which suggests greater reliance on health professionals for dental health. Confirmatory evidence is presented on the negative correlations of depression, anger, and anxiety with Health Internality. Differential approaches to dental treatment are discussed.

    An internal locus of control contributes to positive youth outcomes such as a general well-being and academic success, while also serving as a protective factor against exposure to community violence and reducing negative behaviors like violence. Despite these benefits, very little is known about antecedents of an internal locus of control orientation. Without an understanding of what factors contribute to the development of an internal locus of control, it is not clear how to best encourage its formation. This study uses data from the Project on Human Development in Chicago Neighborhoods to examine whether various mesosystem variables (family management strategies, peer interactions, neighborhood context, and individual-level characteristics) are associated with an internal locus of control orientation among 1,076 youth ages 9-19 living in 78 Chicago neighborhoods. Study participants were Hispanic (46 %), African American (34 %), and White (15 %), and 50 % were female. The findings suggest that, while most levels of the mesosystem influence locus of control orientation, family management strategies are more prominent determinants of an internal locus of control than peers, neighborhood context, or individual characteristics. Parental supervision over the time a youth spends at home and family socioeconomic status are consistent predictors of an internal locus of control, while harsh discipline is associated with an external locus of control. The discussion examines the import of various parenting techniques in shaping an internal locus of control and considers future avenues for research to further unpack how antecedents of locus of control can vary across youth.

    Health locus of control beliefs plays a major role in improving self-management skills of the chronically ill - a main goal in disease management programmes (DMP). This study aims at characterising participants in disease management regarding their health locus of control. Data are based on 4 cross-sectional postal surveys between spring and autumn of 2006 and 2007 within the Health Care Monitor of the Bertelsmann Foundation. Among the 6 285 respondents, 1 266 are chronically ill and not enrolled in a DMP and 327 are participating in a DMP. A high internal locus of control (HLC) occurs significantly less often in DMP patients than in normal chronically ill patients (and healthy people) controlling for age, gender and social class. With increasing age, a high internal locus of control is also significantly less likely. When comparing healthy people, the chronically ill and the DMP participants a social gradient of a high internal locus of control belief can be observed. The weaker internal and higher doctor-related external locus of control of DMP participants should be carefully observed by the physician when trying to strengthen the patients' self-management skills. Evaluators of DMP should take into account the different baselines of DMP patients and relevant control groups and incorporate these differences into the evaluation. © Georg Thieme Verlag KG Stuttgart · New York.

    1992-06-01

    Training in the neurolinguistic programming techniques of shifting perceptual position, visual-kinesthetic dissociation, timelines, and change-history, all based on experiential cognitive processing of remembered events, leads to an increased awareness of behavioral contingencies and a more sensitive recognition of environmental cues which could serve to lower trait anxiety and increase the sense of internal control. This study reports on within-person and between-group changes in trait anxiety and locus of control as measured on the Spielberger State-Trait Anxiety Inventory and Wallston, Wallston, and DeVallis' Multiple Health Locus of Control immediately following a 21-day residential training in neurolinguistic programming. Significant with-in-person decreases in trait-anxiety scores and increases in internal locus of control scores were observed as predicted. Chance and powerful other locus of control scores were unchanged. Significant differences were noted on trait anxiety and locus of control scores between European and U.S. participants, although change scores were similar for the two groups. These findings are consistent with the hypothesis that this training may lower trait-anxiety scores and increase internal locus of control scores. A matched control group was not available, and follow-up was unfortunately not possible.

    Latent profile analysis identified health locus of control profiles among 436 Hispanic Americans who completed the Multidimensional Health Locus of Control scales. Results revealed four profiles: Internally Oriented-Weak, -Moderate, -Strong, and Externally Oriented. The profile groups were compared on sociocultural and demographic characteristics, health beliefs and behaviors, and physical and mental health outcomes. The Internally Oriented-Strong group had less cancer fatalism, religiosity, and equity health attributions, and more alcohol consumption than the other three groups; the Externally Oriented group had stronger equity health attributions and less alcohol consumption. Deriving multidimensional health locus of control profiles through latent profile analysis allows examination of the relationships of health locus of control subtypes to health variables. © The Author(s) 2015.

    The research concerned relations among development at Erikson's first six stages of psychosocial development, locus of control, and several measures of time orientation. The investigation involved 68 female and 65 male high school and university students. Development at Erikson's Stages 1,3, 4, and 5 was significantly related to the I-E Scale, with positive development being associated with internal control. Locus of control was also related to sex and age. Women were found to be more externally controlled than men. Internal control was associated with increasing age over the range from 15 to 25 years. Development at each of Erikson's first five stages was significantly correlated with one or more measures of tempiral relatedness, or integration of perceived past, present, and future time zones. Other measures of time orientation failed to show consistent relations to psychosocial development.

    To investigate general states of the work locus of control and explore the relationship between work locus of control and occupational stress in oil workers. 582 oil workers were investigated by using the General Questionnaire and Occupational Stress Measure Inventory. There were significant differences in WCLS score between two age groups (= 30 years old group and locus of control; values of role ambiguity, working prospect, depression and social support were higher in the group of external locus of control (P locus of control had positive relation with role ambiguity, working prospect, depression, and social support, and negative with interpersonal relationship, promotion, participation, task consistency, challenge, job satisfaction, mental health, self-esteem and coping strategies. In the regression analysis, work locus of control was the major predictive factor of work satisfaction. Work locus of control is associated with many occupational stress factors. The group of extrinsic work locus of control experience more stress in oil workers.

    1975-10-01

    Sixty male alcoholic inpatients were administered the Locus of Control scale (IE), the Activity Preference Questionnaire (APQ), the Manifest Anxiety scale (MAS), and the Tennessee Self Concept scale (TSCS). Ss defined as having an external locus of control appeared significantly more anxious than internal Ss on the MAS; however, no differences were found between groups on the APQ or TSCS scales. The self-report (MAS) and nonobtrusive (APQ) measures of anxiety were not correlated significantly. A differential pattern of correlations was found between the MAS and APQ and TCSC subscale scores. The obtained correlations support the contention that the MAS may measure more accurately a dimension of neuroticism and/or negative self-concept rather than anxiety. Further research appears necessary to investigate the internal consistency and dimensionality of the MAS.

  19. Root locus analysis and design of the adaptation process in active noise control.

    Tabatabaei Ardekani, Iman; Abdulla, Waleed H

    2012-10-01

    This paper applies root locus theory to develop a graphical tool for the analysis and design of adaptive active noise control systems. It is shown that the poles of the adaptation process performed in these systems move on typical trajectories in the z-plane as the adaptation step-size varies. Based on this finding, the dominant root of the adaptation process and its trajectory can be determined. The first contribution of this paper is formulating parameters of the adaptation process root locus. The next contribution is introducing a mechanism for modifying the trajectory of the dominant root in the root locus. This mechanism creates a single open loop zero in the original root locus. It is shown that appropriate localization of this zero can cause the dominant root of the locus to be pushed toward the origin, and thereby the adaptation process becomes faster. The validity of the theoretical findings is confirmed in an experimental setup which is implemented using real-time multi-threading and multi-core processing techniques.

  3. Genetic and environmental influences on the relationship between flow proneness, locus of control and behavioral inhibition.

    Directory of Open Access Journals (Sweden)

    Miriam A Mosing

    Full Text Available Flow is a psychological state of high but subjectively effortless attention that typically occurs during active performance of challenging tasks and is accompanied by a sense of automaticity, high control, low self-awareness, and enjoyment. Flow proneness is associated with traits and behaviors related to low neuroticism such as emotional stability, conscientiousness, active coping, self-esteem and life satisfaction. Little is known about the genetic architecture of flow proneness, behavioral inhibition and locus of control--traits also associated with neuroticism--and their interrelation. Here, we hypothesized that individuals low in behavioral inhibition and with an internal locus of control would be more likely to experience flow and explored the genetic and environmental architecture of the relationship between the three variables. Behavioral inhibition and locus of control was measured in a large population sample of 3,375 full twin pairs and 4,527 single twins, about 26% of whom also scored the flow proneness questionnaire. Findings revealed significant but relatively low correlations between the three traits and moderate heritability estimates of .41, .45, and .30 for flow proneness, behavioral inhibition, and locus of control, respectively, with some indication of non-additive genetic influences. For behavioral inhibition we found significant sex differences in heritability, with females showing a higher estimate including significant non-additive genetic influences, while in males the entire heritability was due to additive genetic variance. We also found a mainly genetically mediated relationship between the three traits, suggesting that individuals who are genetically predisposed to experience flow, show less behavioral inhibition (less anxious and feel that they are in control of their own destiny (internal locus of control. We discuss that some of the genes underlying this relationship may include those influencing the function of

    This cross-sectional study evaluated locus of control and its subscales in Parkinson's disease. A total of 50 consecutive Parkinson's disease participants and 50 healthy volunteers (control group) were enrolled. External locus of control was significantly higher in Parkinson's disease participants, whereas internal locus of control had no significant differences. External locus of control and internal locus of control were correlated in control group, but not in Parkinson's disease. In Parkinson's disease participants, external locus of control was negatively associated with health-related quality of life as well as positively associated with emotional distress and disease severity (but not with disability). After adjusting to confound variables, the associations remained. On the other hand, internal locus of control was negatively associated with depression.

    1999-12-01

    The authors investigated the effects of locus of control expectancies and task difficulty on procrastination. Forty-two college students were administered an academic locus of control scale and a task that was similar to a typical college homework assignment. The students were randomly assigned to 1 of 2 task difficulty levels. Although none of the results involving task difficulty was significant, several results involving locus of control were significant. Specifically, analyses revealed that students with internal locus of control expectancies tended to begin working on the assignment sooner than students with external locus of control expectancies. In addition, students with internal locus of control completed and returned the assignment sooner than students with external locus of control. The results are discussed within the context of J. B. Rotter's (1966, 1975, 1982) social learning theory.

    Full Text Available The primary objective of the study was to construct a normative scale of locus of control for use with students and adults. A corollary of the study was to establish the personality, interest and cognitive correlates of locus of control. Conceptually the instrument is based on attribution theory and on social learning theory. The first edition of the Locus of Control Inventory (LCI was applied to 356 first-year university students during 1994. A factor analysis of the 65 items of the inventory yielded three factors. The factors were interpreted as Autonomy, Internal Control and External Control. Three scales, corresponding to the three factors, were constructed, and yielded reliability coefficients of 0,80; 0,77 and 0,81 respectively. Following this the cognitive, interest and personality correlates of the LCI were determined. The implications of the findings are discussed.

    For many people, the influence of believing in a higher power can elicit powerful effects. This study examined the relationship between God control, health locus of control, and frequency of religious attendance within 838 college students through online surveys. Regression analysis showed that chance and external locus of control and frequency of religious attendance were significant and positive predictors of God Locus of Health Control. The association of powerful others external locus of control and God Locus of Health Control differed by race (stronger in non-Whites than Whites) and somewhat by gender (stronger in women than men). For some people, the role of a supreme being, or God, should be considered when designing programs for improving health behaviors.

    The aim of the research was to indicate whether there are differences between locus of control (LOC) in girls with anorexia readiness syndrome (ARS) and without this syndrome. There was also a question about the relationship between LOC and the tendency to respond in incorrect attitudes towards food, eating and their bodies under stress. The sample consisted of girls aged 13-18 years randomly selected from five public Polish middle and high schools. Tools: 1) Eating Attitudes Questionnaire (EAQ) by B. Ziółkowska; 2) Locus of Control Questionnaire (LOCQ) by G. Krasowicz, A. Kurzyp-Wojnarska, to assess LOC of the subjects. The criterion group (N=23) was formed by girls who received high score in EAQ (signs of ARS) in the first stage of research (N=189). The control group (N = 23) were girls who received a low score in EAQ (no signs of ARS). Subjects with ARS were characterized by more external LOC than girls without any signs of this syndrome (t = -2.898; p control, LOC may play a role as a mediating variable rather than a direct determinant of this syndrome.

Respecto de los primeros, se ha indagado acerca de las atribuciones que se realizaban en torno a las recompensas y sanciones, que ellos distribuían a sus alumnos.Respecto de los segundos, se ha buscado determinar la valoración que estos realizaban de sus profesores, en términos de aquellas atribuciones. Para ello, se utilizaron dos paradigmas clásicamente empleados para verificar la existencia de una norma: el paradigma de la autopresentación (docentes, y el paradigma de los j uicios (alumnos. La cuestión planteada fue determinar si en el caso de los comportamientos distributivos de refuerzos, las causas se atribuían a variables externas -en particular a los receptores de esos refuerzos- y si esas formas de atribución eran conocidas y valoradas o no, por los alumnos. De los resultados, surgió la confirmación de nuestra hipótesis de explicaciones externas en materia de comportamientos distributivos de sanciones en el ámbito de la docencia y la valoración positiva de estas atribuciones por los alumnos.Abstract:This one is a scientific article brings over of the Locus of Distribution, arisen from a study realized with a population of teachers and university pupils.

    Full Text Available Six brothers were accused of gagging and raping a woman. A single male Y-STR profile was obtained from vaginal smear swab and clothes of the victim, which did not match with the DNA profile of the accused brothers. As a reference point, the blood sample of their father (aged 87 years was also analyzed with the same kit. The Y-STR haplotype of all six brothers was found to be the same as that of their father except at locus DYS458. At this locus, while the eldest, second and fourth siblings share allele 18 with their father, a loss of one repeat (allele 17 instead of 18 is observed in the third son while fifth and sixth siblings have allele 19 representing a gain of one repeat. Thus, two changes viz. a gain (twice and loss of one repeat at this locus in one generation is both interesting and unusual.

    Martins, Raquel Gomes; Carvalho, Irene Palmares

    2013-07-01

    To identify patients' preferences for models of communicating bad news and to explore how such preferences, and the reasons for the preferences, relate with personality characteristics, specifically patients' health locus of control (HLC): internal/external and 'powerful others' (PO). Seventy-two patients from an oncology clinic watched videotaped scenarios of a breaking bad news moment, selected the model they preferred, filled an HLC scale and were interviewed about their choices. Data were analyzed with Chi-square, Kruskal-Wallis and Mann-Whitney tests. Interviews were content-analyzed. 77.8% preferred an "empathic professional", 12.5% a "distanced expert" and 9.7% an "emotionally burdened expert". Preferences varied significantly with HLC scores (patients with higher internal locus of control (ILC) and lower PO preferred the empathic model), presence of cancer, age and education. Patients explained their preferences through aspects of Caring, Professionalism, Wording, Time and Hope. ILC registered significant differences in regards to Wording and Time, whereas PO was associated with Hope and Time. HLC is an important dimension that can help doctors to better know their patients. Knowing whether patients attribute their health to their own behaviors or to chance/others can help tailor the disclosure of bad news to their specific preferences.

    Strawberry (Fragaria sp.) stands as an interesting model for studying flowering behaviour and its relationship with asexual plant reproduction in polycarpic perennial plants. Strawberry produces both inflorescences and stolons (also called runners), which are lateral stems growing at the soil surface and producing new clone plants. In this study, the flowering and runnering behaviour of two cultivated octoploid strawberry (Fragaria × ananassa Duch., 2n = 8× = 56) genotypes, a seasonal flowering genotype CF1116 and a perpetual flowering genotype Capitola, were studied along the growing season. The genetic bases of the perpetual flowering and runnering traits were investigated further using a pseudo full-sibling F1 population issued from a cross between these two genotypes. The results showed that a single major quantitative trait locus (QTL) named FaPFRU controlled both traits in the cultivated octoploid strawberry. This locus was not orthologous to the loci affecting perpetual flowering (SFL) and runnering (R) in Fragaria vesca, therefore suggesting different genetic control of perpetual flowering and runnering in the diploid and octoploid Fragaria spp. Furthermore, the FaPFRU QTL displayed opposite effects on flowering (positive effect) and on runnering (negative effect), indicating that both traits share common physiological control. These results suggest that this locus plays a major role in strawberry plant fitness by controlling the balance between sexual and asexual plant reproduction.

    This study examined psychometric properties of the Levenson's Locus of Control Scale among Iranian infertile patients. In all, 312 infertile patients completed the Levenson's Locus of Control Scale and Hospital Anxiety and Depression Scale. The confirmatory factor analysis indicated that the original three-factor model of Levenson's Locus of Control Scale was adequate ( χ 2 / df = 2.139; goodness-of-fit index = 0.88; root mean square error of approximation = 0.061; and standardized root mean square residual = 0.076). The Cronbach's alpha of the subscales ranged from 0.56 to 0.67. The Levenson's Locus of Control Scale subscales significantly correlated with anxiety and depression, showing an acceptable convergent validity. In conclusion, the Levenson's Locus of Control Scale has adequate reliability and validity and can be used to measure locus of control orientation in Iranian infertile patients.

    Racial disparities in cognitive outcomes may be partly explained by differences in locus of control. African Americans report more external locus of control than non-Hispanic Whites, and external locus of control is associated with poorer health and cognition. The aims of this study were to compare cognitive training gains between African American and non-Hispanic White participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study and determine whether racial differences in training gains are mediated by locus of control. The sample comprised 2,062 (26% African American) adults aged 65 and older who participated in memory, reasoning, or speed training. Latent growth curve models evaluated predictors of 10-year cognitive trajectories separately by training group. Multiple group modeling examined associations between training gains and locus of control across racial groups. Compared to non-Hispanic Whites, African Americans evidenced less improvement in memory and reasoning performance after training. These effects were partially mediated by locus of control, controlling for age, sex, education, health, depression, testing site, and initial cognitive ability. African Americans reported more external locus of control, which was associated with smaller training gains. External locus of control also had a stronger negative association with reasoning training gain for African Americans than for Whites. No racial difference in training gain was identified for speed training. Future intervention research with African Americans should test whether explicitly targeting external locus of control leads to greater cognitive improvement following cognitive training.

  20. Multilocus genetic models of handedness closely resemble single-locus models in explaining family data and are compatible with genome-wide association studies.

    McManus, I C; Davison, Angus; Armour, John A L

    2013-06-01

    Right- and left-handedness run in families, show greater concordance in monozygotic than dizygotic twins, and are well described by single-locus Mendelian models. Here we summarize a large genome-wide association study (GWAS) that finds no significant associations with handedness and is consistent with a meta-analysis of GWASs. The GWAS had 99% power to detect a single locus using the conventional criterion of P < 5 × 10(-8) for the single locus models of McManus and Annett. The strong conclusion is that handedness is not controlled by a single genetic locus. A consideration of the genetic architecture of height, primary ciliary dyskinesia, and intelligence suggests that handedness inheritance can be explained by a multilocus variant of the McManus DC model, classical effects on family and twins being barely distinguishable from the single locus model. Based on the ENGAGE meta-analysis of GWASs, we estimate at least 40 loci are involved in determining handedness. © 2013 New York Academy of Sciences.

  3. Are there gender differences in locus of control specific to alcohol dependence?

    2017-01-01

    To investigate gender differences in locus of control in an alcohol-dependent population. Locus of control helps to explain behaviour in terms of internal (the individual is responsible) or external (outside forces, such as significant other people or chance, are responsible) elements. Past research on gender differences in locus of control in relation to alcohol dependence has shown mixed results. There is a need then to examine gender and locus of control in relation to alcohol dependence to ascertain the veracity of any locus of control differences as a function of gender. The Multidimensional Health Locus of Control form-C was administered to clients from alcohol dependence treatment centres in the West of Scotland. Independent t-tests were carried out to assess gender differences in alcohol dependence severity and internal/external aspects of locus of control. One hundred and eighty-eight (53% females) participants were recruited from a variety of alcohol dependence treatment centres. The majority of participants (72%) came from Alcoholics Anonymous groups. Women revealed a greater internal locus of control compared with men. Women also had a greater 'significant others' locus of control score than men. Men were more reliant on 'chance' and 'doctors' than women. All these trends were not, however, statistically significant. Gender differences in relation to locus of control and alcohol dependence from past studies are ambiguous. This study also found no clear statistically significant differences in locus of control orientation as a function of gender. This article helps nurses to contextualise health behaviours as a result of internal or external forces. It also helps nursing staff to better understand alcohol dependence treatment in relation to self-efficacy and control. Moreover, it highlights an important concept in health education theory. © 2016 John Wiley & Sons Ltd.

    The objective of this study was to examine the factor structure, reliability, and validity of the Form C of the Multidimensional Health Locus of Control scales in adolescents. A confirmatory factor analysis indicated that adequate fit of a four-factor model and the internal consistency of the scales were adequate. Criterion validity of the four scales of the Form C of the Multidimensional Health Locus of Control was also supported by significant correlations with measures of pain-related self-efficacy, anxiety, and coping strategies. The results indicate that the four Form C of the Multidimensional Health Locus of Control scale scores are reliable and valid and therefore support their use to assess pain-related locus of control beliefs in adolescents.

  5. Single Locus Maintains Large Variation of Sex Reversal in Half-Smooth Tongue Sole (Cynoglossus semilaevis).

    Science.gov (United States)

    Jiang, Li; Li, Hengde

    2017-02-09

    Sex determination is a fundamental biological process for individual sex development and population sex ratios. However, for some species, the primary sex might be altered during development, and individuals can develop into the opposite sex. Sex reversal may happen in insects, reptiles, amphibians, and fishes. In half-smooth tongue sole ( Cynoglossus semilaevis ), some genetically female fish irreversibly reverse to pseudomales, resulting in higher costs in aquaculture owing to a lower growth rate of male fish during a 2-yr growth period. Here, we identified a locus with large controlling effect on sex reversal in the half-smooth tongue sole through genome-wide association study with high-density single nucleotide polymorphisms (SNPs). This SNP is located at the third intron of the F-box and leucine rich repeat protein 17 ( FBXL17 ) gene on the Z chromosome, and it has two alleles, A and T. Genetic females with Z A W genotypes will never reverse into phenotypic males, but those with Z T W genotypes can sometimes undergo sex reversal. This SNP explains 82.7% of the genetic variation, or 58.4% of the phenotypic variation. Based on our results, a reproductive management program could be developed to improve the phenotypic female ratio in aquaculture, and elucidate the mechanism of sex reversal in half-smooth tongue sole. We expect that these findings will have a substantial impact on the population management in many harvested species where sex reversal occurs. Copyright © 2017 Jiang and Li.

    DNA replication in the human β-globin locus is subject to long-distance regulation. In murine and human erythroid cells, the human locus replicates in early S phase from a bidirectional origin located near the β-globin gene. This Hispanic thalassemia deletion removes regulatory sequences located over 52 kb from the origin, resulting in replication of the locus from a different origin, a shift in replication timing to late S phase, adoption of a closed chromatin conformation, and silencing of globin gene expression in murine erythroid cells. The sequences deleted include nuclease-hypersensitive sites 2 to 5 (5′HS2-5) of the locus control region (LCR) plus an additional 27-kb upstream region. We tested a targeted deletion of 5′HS2-5 in the normal chromosomal context of the human β-globin locus to determine the role of these elements in replication origin choice and replication timing. We demonstrate that the 5′HS2-5-deleted locus initiates replication at the appropriate origin and with normal timing in murine erythroid cells, and therefore we conclude that 5′HS2-5 in the classically defined LCR do not control replication in the human β-globin locus. Recent studies also show that targeted deletion of 5′HS2-5 results in a locus that lacks globin gene expression yet retains an open chromatin conformation. Thus, the replication timing of the locus is closely correlated with nuclease sensitivity but not globin gene expression. PMID:10891496

    Health locus of control may be an important predictor of health care utilization. We analyzed associations between health locus of control and frequency of emergency department visits and hospital admissions, and investigated self-rated health as a potential mediator. Overall, 863 patients in an urban emergency department completed the Multidimensional Health Locus of Control instrument, and self-reported emergency department use and hospital admissions in the last year. We found small but significant associations between Multidimensional Health Locus of Control and utilization, all of which were mediated by self-rated health. We conclude that interventions to shift health locus of control may change patients' perceptions of their own health, thereby impacting utilization.

    Health locus of control defined as individual beliefs based on past experiences in health issues and having external or internal control over them, could affect health. Health locus of control plays a role in health behaviors. We aimed to investigate the relationship between health locus of control and health behavior in emergency medical personnel in Ahvaz during 2016. This is a cross-sectional descriptive study, which began in August 2016 for a period of six months on 215 emergency medical personnel in Ahvaz who were selected randomly. The data were collected by a demographic questionnaire, Rotter's locus of control questionnaire, and health behavior questionnaire and analyzed using SPSS software, version 22. The correlation between variables was estimated by Pearson's correlation coefficient and independent t test. The level of significance for all statistical tests was set at 0.05. We found no significant relationship between health locus of control (external and internal) and health behavior (P>0.05).Health behaviors were very good in terms of personal health (86.5%), nutrition (53%), and sleep and rest (48.4%), and poor in terms of physical activity (52.6%) and stress management (79.5%). Furthermore, 79.5% of the emergency personnel, in general, had poor heath behaviors. Leaders and officials in the field of health must necessarily design programs in relation to health locus of control and the factors developing and affecting it as well as the role of health locus of control in doing correct behaviors.

    Locus of control, i.e. the degree of an individual's belief on the control of his/her life, has been related to many health outcomes, including weight loss in overweight/obese individuals. No information is available on the impact of locus of control in maintaining weight loss. We aimed to investigate the effect of locus of control in weight loss maintenance and explore potential associations with lifestyle factors. Study participants included 239 individuals (41% males) who had lost at least 10% of body weight in the past and either maintained the loss (maintainers: weight maintenance of at least 10% of initial weight) or regained it (regainers). Locus of control was defined by a relevant multi-dimensional scale; participants were categorised to internals and externals, based on "internal" and "others" sub-scales. A significant interaction was found between locus of control and weight loss maintenance status (p locus of control. Individualised treatment, according to locus of control, may increase weight loss maintenance rates in former overweight/obese individuals. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Given rising technology use across all demographic groups, digital interventions offer a potential strategy for increasing access to health information and care. Research is lacking on identifying individual differences that impact willingness to use digital interventions, which may affect patient engagement. Health locus of control, the amount of control an individual believes they have over their own health, may predict willingness to use mobile health (mHealth) applications ('apps') and online trackers. A cross-sectional study (n = 276) was conducted to assess college students' health locus of control beliefs and willingness to use health apps and online trackers. Internal and powerful other health locus of control beliefs predicted willingness to use health apps and online trackers while chance health locus of control beliefs did not. Individuals with internal and powerful other health locus of control beliefs are more willing than those with chance health locus of control beliefs to utilize a form of technology to monitor or change health behaviors. Health locus of control is an easy-to-assess patient characteristic providers can measure to identify which patients are more likely to utilize mHealth apps and online trackers.

    Full Text Available This study analyzes the relationship between locus of control and interpersonal relations structures in Argentina. After a representative sample (n = 1500 of households in seven major urban centers (>200,000 inhabitants, it examines the relationship between the externality of locus of control and different aspects of personal networks of each respondent. The results show that people having more relations experiment lower levels of externality of locus of control. Likewise, lower levels of externality are informed when personal ties outside the neighborhood are available, as well as ties high educational level. In this regard, significant associations are verified between control and personal relations structures.

    Burnout is a major problem for nursing. There is a strong relationship between work stress and emotional exhaustion. Although studies report a negative correlation between the internal locus of control and emotional exhaustion and work stress, the number of studies available on the subject is limited. This study intends to examine the extent to which the relationship between work stress and emotional exhaustion is mediated by nurses' internal locus of control. The study adopted a cross-sectional survey design. The data were analyzed using structural equation modeling techniques. The study sample consisted of 347 nurses who worked in a university hospital in Izmir, Turkey and who agreed to participate in the study. The Work-Related Strain Inventory was used to evaluate the nurses' work stress level, Maslach Burnout Inventory was used to evaluate their emotional exhaustion levels, and the Locus of Control Scale was used to evaluate the internal locus of control. The variables of the study were based on the Neuman Systems Model. Work stress was positively related to internal locus of control (β3 = .21, p 0.1). Internal locus of control was negatively related to emotional exhaustion (β = -.14, p Work stress is directly (β = .87, p Work stress is directly (β = .87, p work stress was mediated, the impact of internal locus of control was limited. It is recommended that different variables be included in future studies so that they can mediate the relationship between work stress and emotional exhaustion.

    Objective: To investigate relationship between emotional intelligence and health locus of control in married women with breast cancer disease. Study Design: Cross sectional study. Place and Duration of Study: The data was collected from Nuclear Oncology and Radiology Institute (NORI Hospital) Islamabad (n=210) and from Combined Military Hospital (CMH) Rawalpindi (n=101). Data collection was completed between the period from Oct 2013 to Feb 2014. Patients and Methods: The sample was selected using non- probability sampling technique. Collected breast cancer patients sample was n= 311 whose age range was from 18-80 years. A biographical sheet that contain personal and disease information of patient, and two scales were used: Self Report Measure of Emotional Intelligence (Khan and Kamal, 2010), and Multidimensional Health Locus of Control (Wallston, Stein, and Smith, 1994) were used to assess the constructs explored in this study. Results: Results depict that there was significant positive correlation between emotional intelligence (EI), including its sub scales Emotional Self-Regulation Skills (ESRS), Emotional Self Awareness Skills (ESAS), and Interpersonal Skills Scale (ISS) with the Internal Health Locus of Control (IHLOC). Doctors Health Locus of Control (DHLOC) also have significant relationship to emotional intelligence's all sub divisions, whereas external health locus of control including Chance Health Locus of Control (CHLOC) and Powerful Other people Health Locus of Control (PHLOC) both are related to psychological distresses but it was observed in breast cancer population that chance was significantly correlated to ESAS, and ISS and powerful other people locus. Further on group comparison One Way Analysis of Variance (ANOVA) depicted no significant difference on disease stage groups. Conclusion: The strength factors of EI and HLOC are highlighted in current study. It was concluded that Emotional Intelligence (EI) and health locus of control (IHLOC

    We investigated the health and illness concepts of 53 healthy children aged 8 to 14 years using a modified illness and health locus of control scale (KKG, Lohaus and Schmitt, 1989) with the scales internal, external-p (powerful others) and external-c (chance). A comparison of the results with those on self-esteem (FSK 4-6), anxiety (CMAS-R) and hopelessness (HSC) scales showed a decrease in externality, but not an increase in internality, with increasing age and a correlation between self-confidence and a more internal locus of control. The influence of children's health locus of control on treatment compliance is discussed.

    The effect of high and low assertiveness on locus of control and health problems was examined with 78 direct-service workers in mental health and mental retardation settings in northeastern Pennsylvania. The direct-service workers completed the Rathus (1973) Assertiveness Schedule, the Rotter (1966) Internal-External Locus of Control Scale, and a health-problems inventory. Highly assertive individuals were found to be more internally controlled and to experience fewer health problems than were individuals low in assertiveness.

    Non-adherence is a significant factor contributing to medication wastage. Whilst there is some evidence on the influence of patients' health locus of control in relation to adherence, there has been little inquiry into its relationship with mediation wastage. To determine the relationship between medication adherence and health locus of control as well as medication wastage and health locus of control in patients with chronic conditions. Outpatients having a diagnosis of asthma, cardiovascular conditions, or diabetes participated in a cross-sectional study employing a self-administered questionnaire. The questionnaire determined presence of unused medication (wastage), adherence using 'Tool for Adherence Behaviour Screening' (TABS), and health locus of control using 'Multidimensional Health Locus of Control' (MHLC) scale Form C. Logistic regression was performed to ascertain the effects of MHLC and demographics in relation to adherence and wastage. MHLC beliefs were divided into 8 types of health locus of control. One-Way ANOVA was used to assess differences between conditions and belief types. P-values ≤ .05 were considered significant. There were 330 patients recruited (58% male; age, mean±(SD): 61 ± 15 years; 110 asthma, 110 cardiovascular, 110 diabetes). In terms of health locus of control, females had higher 'doctors' beliefs (p = .054) and significantly lower 'other people' beliefs (p = control. 'Yea-sayers' had the least presence of unused medication, followed by 'pure internal' believers. 'Pure powerful others external' had the highest presence of unused medication. Healthcare professionals should take into account patients' health locus of control beliefs whilst conducting an intervention with patients; this can impact positively medication adherence and minimisation of medication wastage.

    1997-12-01

    The purpose of this study was to examine relationships among scores on vocational interests, self-esteem, and locus of control for high school students. Grade and sex differences were also examined. 1364 high school students ranging in age from 14 to 19 years of age were administered the Coopersmith Self-esteem Inventory, Nowicki-Strickland Locus of Control Scale for Children, and the Strong-Campbell Interest Inventory. High school students with higher scores on self-esteem and showing an orientation toward internal locus of control expressed more interests in a variety of vocational themes than adolescents with lower scores on self-esteem and scores for external locus of control. Sex and grade differences in vocational interests of adolescents were also noted. The findings were discussed in light of theoretical and practical considerations.

    The purpose of this study was to investigate the relationship between self-concept and locus of control in interpersonal conflict resolution approaches and to determine the predictors of conflict resolution approach choices. The study included 345 students aged between 18 and 28 years that were studying at universities in Ankara. Data were collected using the Interpersonal Conflict Resolution Approaches Scale to measure conflict resolution approaches, the Social Comparison Scale to measure self-concept, and the Internal-External Locus of Control Scale to measure locus of control. It was observed that confrontation approach to interpersonal conflict was predicted by self-concept (beta = 0.396, P interpersonal conflict resolution process. Individuals with a positive self-concept and an internal locus of control adopted solutions to interpersonal conflict resolution that were more effective and constructive.

    Locus of Control (LoC) refers to an individuals' perception of whether they are in control of life events. Health Locus of Control refers to whether someone feels they have influence over their health. Health Locus of Control has not been studied in any depth in voice-disordered patients. The objective of this study was to examine Health Locus of Control in three patient groups: (1) Spasmodic Dysphonia, (2) Functional Dysphonia and (3) a nondysphonic group with Nonlaryngeal Dystonia. LoC was measured and compared in a total of 57 patients using the Multidimensional Health Locus of Control Scales (diagnostic specific) Form C. Internal, Chance, and Powerful others LoC were measured and comparisons were made using one-way analysis of variance. Contrary to expectations Internal LoC was found to be significantly higher in the Functional Dysphonia group when compared to the other two groups. There was no significant difference between the groups in Chance or Powerful others LoC. The two organic groups, Spasmodic Dysphonia and Nonlaryngeal Dystonia, were more alike in Internal Health Locus of Control than the Functional Dysphonia group. The diagnostic nature of the groups was reflected in their LoC scores rather than their voice loss. These results contribute to the debate about the etiology of Spasmodic Dysphonia and will be of interest to those involved in the psychology of voice and those managing voice-disordered patients.

    This study examines self-esteem and locus of control in adult children of alcoholics. We assessed these measures in 195 professional adults in relation to alcoholism and functioning in the family of origin. Although the presence of parental alcoholism was not a predictor of significant differences in adult self-esteem or locus of control, familial dysfunction was reflected in significant differences in self-esteem. This suggests that parental alcoholism does not necessarily result in personality differences in adult children.

    Past research has shown that locus of control plays an important role in a wide range of behaviors, such as academic achievement and positive social behaviors. However, little is known about whether locus of control plays the same role in minority adolescents' peer relationships. The current study examined ethnic differences in the associations between locus of control and peer relationships in early adolescence using samples from the Early Childhood Longitudinal Study (ECLS-K: 5,612 Caucasian, 1,562 Hispanic, 507 Asian, and 908 African-American adolescents) and the National Education Longitudinal Study (NELS: 8,484 Caucasian, 1,604 Hispanic, and 860 Asian, and 1,228 African American adolescents). Gender was approximately evenly split in both samples. The results from the two datasets were highly consistent. Significant interactions between ethnicity and locus of control indicated that having a more internal locus of control was particularly important for Caucasian students' peer relationships (ECLS-K) and social status (NELS), but less so for Asian, Hispanic, and African American students. Our findings suggest that the role of locus of control in peer relationship is contingent upon culture.

    To investigate the association between political trust in the Riksdag and lack of belief in the possibility to influence one's own health (external locus of control), taking horizontal trust into account. The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample of 28,198 persons aged 18-80 years participated. Logistic regression models were used to investigate the associations between political trust in the Riksdag (an aspect of vertical trust) and lack of belief in the possibility to influence one's own health (external locus of control). The multiple regression analyses included age, country of birth, education, and horizontal trust in other people. A 33.7% of all men and 31.8% of all women lack internal locus of control. Low (external) health locus of control is more common in higher age groups, among people born outside Sweden, with lower education, low horizontal trust, low political trust, and no opinion concerning political trust. Respondents with not particularly strong political trust, no political trust at all and no opinion have significantly higher odds ratios of external locus of control throughout the multiple regression analyses. Low political trust in the Riksdag seems to be independently associated with external health locus of control.

    Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups. First, the locus of control was measured in both groups through a pretest, and cognitive-behavioral techniques were then taught to the intervention group during eight 45 to 90-minute sessions. The locus of control in patients of both groups was finally re-measured through a posttest. Data were collected using Rotter's Locus of Control Inventory. The Wilcoxon test and Mann-Whitney U test were respectively used in SPSS18 for data analysis. In the pretest and posttest stages respectively, 4.8% and 14.3% of samples in the control group as well as 14.3% and 33.3% of samples in the intervention group enjoyed internal locus of control. The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive

    Studies in many systems have led to the model that the human β-globin locus control region (LCR) regulates the transcription, chromatin structure, and replication properties of the β-globin locus. However the precise mechanisms of this regulation are unknown. We have developed strategies to use homologous recombination in a tissue culture system to examine how the LCR regulates the locus in its natural chromosomal environment. Our results show that when the functional components of the LCR, as defined by transfection and transgenic studies, are deleted from the endogenous β-globin locus in an erythroid background, transcription of all β-globin genes is abolished in every cell. However, formation of the remaining hypersensitive site(s) of the LCR and the presence of a DNase I-sensitive structure of the β-globin locus are not affected by the deletion. In contrast, deletion of 5′HS5 of the LCR, which has been suggested to serve as an insulator, has only a minor effect on β-globin transcription and does not influence the chromatin structure of the locus. These results show that the LCR as currently defined is not necessary to keep the locus in an “open” conformation in erythroid cells and that even in an erythroid environment an open locus is not sufficient to permit transcription of the β-like globin genes.

    We evaluated the effect of cognitive training among 1,534 participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) randomized controlled trial (RCT) on 5-year improvements in 3 cognitive-specific measures of locus of control-internal, chance, and powerful others. ACTIVE was a multisite RCT (age > or = 65), with 4 groups (memory, reasoning, speed of processing, and no-contact control). Complete 5-year follow-up data were available for 1,534 (55%) of the 2,802 participants. A propensity score model was used to adjust for potential attrition bias. Clinically important improvements (and decrements) in the cognitive-specific locus of control scale scores were defined as greater than or equal to 0.5 SD (medium) and greater than or equal to 1.0 SD (large). Multinomial logistic regression was used to simultaneously contrast those who improved and those who declined with those whose locus of control scale score was unchanged. Statistically significant effects reflecting medium-sized (> or = 0.5 SD) improvements in internal locus of control between baseline and the 5-year follow-up were found for the reasoning and speed of processing intervention groups who were 76% (p control group. No improvement effects were found on the chance or powerful others locus of control measures or for the memory intervention group. Cognitive training that targets reasoning and speed of processing can improve the cognitive-specific sense of personal control over one's life in older adults.

    Two hypotheses were investigated in the present study: 1) Patients with full posttraumatic stress symptoms following spinal cord injury (SCI) would experience more general health problems than those with partial posttraumatic stress disorder (PTSD), with no-PTSD and the control group; 2) Patients with full PTSD would endorse the external locus of control more than those with partial PTSD, no-PTSD and the control group. Sixty-two patients were recruited from a specialized rehabilitation clinic for spinal cord injury. The control group comprised 60 participants without SCI. Patients with SCI were assessed using the Posttraumatic Stress Disorder Checklist, the General Health Questionnaire-28 (GHQ-28) and the Multidimensional Health Locus of Control (MHLC). The control group was assessed using the GHQ-28 and the MHLC. The full PTSD group experienced more somatic problems, anxiety, social dysfunction and depression than the partial PTSD, the no-PTSD and the control groups. The results also showed that the full PTSD group endorsed significantly more external health locus of control than the control group. However, no significant differences were found between the three patient groups in health locus of control. The three PTSD sub-scales were positively correlated with general health problems. Further analyses showed that partial PTSD patients with paraplegia and partial PTSD patients whose SCI had a medically related cause were more likely to report less internal locus of control than other patients. Patients who suffered from full PTSD experienced more general health problems than those with fewer PTSD symptoms and those without SCI. External locus of control was a distinctive strategy that SCI-PTSD patients used in coping with the effects of SCI-PTSD.

    2003-04-01

    The present study was designed to investigate the relationships between premenstrual symptomatology, locus of control, anxiety, and depression in women with normal menstrual cycles. Sixty-nine female participants completed a survey, comprised of the Menstrual Distress Questionnaire (MDQ; Moos, 1968), Levenson's (1981) locus of control scales, the Depression Anxiety Stress Scale (DASS; Lovibond and Lovibond, 1995), and a questionnaire constructed by the researchers based on the DSM-IV criteria for Premenstrual Dysphoric Disorder (PMDD). Both overall and specific subtypes of premenstrual symptomatology were found to correlate with external locus of control, anxiety, and depression. In addition, locus of control was found to moderate the relationship between premenstrual symptomatology, anxiety and depression. Finally, women who were in the premenstrual phase when completing the questionnaire scored significantly lower on the internal scale than those in either the follicular or early luteal phases. It was concluded that an external locus of control may be associated with a susceptibility to depression or anxiety when certain premenstrual or postmenstrual changes are experienced.

    Full Text Available AbstractIntroduction The health locus of control is defined as the perception of individuals in relation to whom they believe to be responsible for their health condition, including low back pain.Objective To identify whether individuals suffering from chronic low back pain in active physical therapy treatment believe they are responsible for their own condition.Material and methods Cross-sectional study involving 28 patients under active physical therapy treatment for non-specific chronic low back pain. Sociodemographic data and low back characteristics — including disability and pain severity — were collected. The Multidimensional Health Locus of Control (MHLC scale was used to assess the health locus of control.Results Participants undergoing active low back pain treatment presented a mean (SD of 26 points (11.40 in a 0–100 point scale for disability and 6.39 points (2.24 on a 0–10 scale for pain. In relation to the health locus of control, the means (SD for internal, external and chance subscales were, respectively: 29.32 (3.98, 24.75 (3.58, and 13.71 (6.67. 82.1% of the participants presented higher rates for internal locus of control.Conclusion Patients undergoing active treatment for chronic low back pain believe they are responsible for their own condition. Further longitudinal studies may determine whether active treatments affect the beliefs of low back pain patients.

    Full Text Available The intensive reforms taking place in general education field in Georgia impose considerable stress to those engaged in teaching profession. This may gradually lead to the condition of professional burnout of teachers. According to the conducted research some teachers have experienced burnout while others did not. The purpose of the present research is to identify how the personal quality such as control of locus may have influenced the level of burnout in Georgian teachers. Two self-assessment instruments, Rotter Scale and Maslach Burnout Inventory (MBI, were used in this research to measure control of locus type and level of burnout among Georgian teachers. Two questionnaires were distributed among 407 teachers at Public schools of Georgia. After dismissing inaccurately filled out questionnaires the analysis was conducted based on the data received from 373 questionnaires. The research findings revealed that Georgian teachers with internal locus of control are less likely to become professional burnout victims. Significant correlations proved to exist between locus of control orientation and teacher burnout on Emotional Exhaustion (EE and Personal Achievements (PA subscales of MBI. The article explores the opportunities to change locus of control from external to internal as a part of teacher professional development activities guided by school Principals and through redesigning of teacher preparation programs in order to make teachers more resistant to professional burnout.

    Full Text Available The aim of this study is to investigate the relationships between the affective learning needs namely, self-efficacy and locus of control, learning efforts and academic achievement among engineering students. For this purpose, a survey was conducted on first year engineering students from two technical universities in Malaysia. Self-efficacy and locus of control were assessed using existing instruments while learning efforts were assessed using a specifically designed instrument based on Carbonaro’s model of learning effort. Academic achievement data were based on cumulative grade point average (CGPA obtained from self-report by participants. The findings indicate that females engineering students tend to have higher self-efficacy compared to males while both groups have similar locus of control and invest in similar learning efforts. Only locus of control is found to be related to academic achievement while self-efficacy is found to be related to efforts. In conclusion, locus of control seems to be an important factor in predicting academic achievement among engineering students.

    This study explored God locus of control beliefs (i.e., God's control over behavior) regarding their influence on alcohol use and sexual behavior as an alternative religiosity measure to religious behaviors, which does not capture perceived influence of religiosity. Additionally, demographic differences in religious beliefs were explored. College students aged 18-24 (N = 324) completed a survey between April 2012 and March 2013. Principal components and multivariate analyses were conducted. Findings suggest that measures provide reliable, valid data from college students. God locus of control is linked to not consuming alcohol or engaging in sex. There were differences regarding relationship status and religious denomination. God locus of control beliefs are an appropriate construct for collecting data about college students' religiosity. Furthermore, health educators at faith-based institutions could incorporate this construct into their programming, encouraging abstinence but also behaving responsibly for those who do drink and are sexually experienced.

    The factor structure of the Multidimensional Health Locus of Control scale remains in question. Additionally, research on health belief differences between Black and White respondents suggests that the Multidimensional Health Locus of Control scale may not be invariant. We reviewed the literature regarding the latent variable structure of the Multidimensional Health Locus of Control scale, used confirmatory factor analysis to confirm the three-factor structure of the Multidimensional Health Locus of Control, and analyzed between-group differences in the Multidimensional Health Locus of Control structure and means across Black and White respondents. Our results indicate differences in means and structure, indicating more research is needed to inform decisions regarding whether and how to deploy the Multidimensional Health Locus of Control appropriately.

  10. The Limits of the Use of Locus of Control in Industrial Psychology: A Critical Evaluation

    2016-10-01

    Full Text Available Locus of control is a personality variable that is employed by researchers from diverse disciplines. This article examines the limits of the construct’s usage in industrial and organizational psychology. Although locus of control is documented to predict a wide array of workplace behavior such as job satisfaction, job performance and turnover intention, some important conceptual, methodological and empirical flaws raise suspicions on the explanations proposed by researchers. Considering the shortage of experimental and longitudinal evidence, it is argued that the causal direction of the well-established correlations between locus of control and other organizational behavioral variables might be the opposite of the theory’s expectation. It is also claimed that some related constructs such as self-efficacy and belief in a just world might provide further explanations for observed correlations.

    2007-06-01

    The authors examined the relationship between jurors' locus of control and defendants' attractiveness in death penalty sentencing. Ninety-eight participants voluntarily served as mock jurors. The authors administered J. B. Rotter's (1966) Internal-External Locus of Control Scale to participants and then randomly assigned them to a group with either an attractive or an unattractive defendant (represented by photographs). Participants read a murder vignette and selected a punishment--either a lifetime jail sentence or the death penalty-for the defendant. Results indicated that neither jurors' locus of control nor defendants' attractiveness influenced sentencing. However, jurors' age and gender significantly influenced sentencing. Men, with the exception of the youngest men, were more likely than women to choose the death penalty. Additionally, young women were more likely than older women to select the death penalty. The authors discuss the implications of these results for the study of jury behavior and bias.

    1992-12-01

    Examined the relationships between negative events, locus of control, social support, and psychological adjustment in an early adolescent sample. Of interest were the potential stress-buffering effects of social support and the conjunctive effects of social support and locus of control upon adjustment. Family support was positively related to adjustment in several domains, whereas school support was only related to school competence. Peer support was positively related to peer competence and anxiety, and negatively related to school competence. Examination of the buffering hypothesis suggested that both family and school support served to moderate the relationship between negative events and school competence. Conjunctive effects were also detected in that school support buffered number of negative events best for those individuals with an internal locus of control for successes.

    Rohsenow, D J; O'Leary, M R

    1978-02-01

    Research literature dealing with the relationships of locus of control to age, ability to function, and personality traits is reviewed. Results are contradictory on the relationship of locus of control in alcoholics to age, social desirability, and intellectual functioning. There is some tendency for internality to be related to better social functioning and the defenses of denial, intellectualization, and repression. There is some possible support for a relationship of externality and anxiety, and externality does appear related to helplessness, depression, isolation, general clinical pathology, and the defense of turning against another. No relationship has been found between locus of control and field dependence for alcoholics. Methodological difficulties have included problems with sampling, unsystematic research, assuming homogeneity of alcoholic samples, and assuming linearity and unidimensionality of the scales. Possible research which could clarify some of the areas are suggested.

    The contributions of frequency of positive and negative self-statements and their ratio, locus of control, and depression in prediction of self-esteem were examined. Volunteers were 145 college students (100 women and 45 men) who were administered the Coopersmith Self-esteem Inventory-Adult Form, Automatic Thought Questionnaire-Revised, the Beck Depression Inventory, and the Rotter Internal-External Locus of Control Scale. Intercorrelations suggested significant relationships among variables. The magnitude of the relationship was strongest between the frequency of negative self-statements and self-esteem. These results are consistent with and lend further support to prior studies of Kendall, et al. and Schwartz and Michaelson.

    Full Text Available Acute lymphoblastic leukemia (ALL is a very distressing experience for children and requires a special effort of adjustment. Therefore, it seems to be crucial to explore coping resources for the experienced risk condition. In this sense, the study focuses on coping strategies and locus of control in children with ALL during the treatment phase, and on their possible relation. The correlation between children and maternal coping strategies is also investigated. The participants involved were an experimental group of 40 children with ALL and their mothers, and 30 healthy children as the control group. The tools used were: the Child Behavioral Style Scale and the Monitor-Blunter Style Scale to assess the coping strategies of children and mothers; the locus of Control Scale for Children to analyze the children’s perception of controlling the events. Both children with ALL and their mothers resorted to monitoring coping strategies with a statistically significant rate of occurrence (children: M=17.8, SD=3.8; mothers: M=10.48, SD=3.4. The data concerning the locus of control show this tendency towards internal causes (M=53.1, SD=4.7. There were statistically significant correlations between monitoring coping strategies and external locus of control (r=0.400, P<0.05. The results gained from the control group are almost equivalent. The outcomes show several interesting resources of the psychological functioning of children as well as of their mothers.

    Diabetic foot affects more than 25% of diabetic patients and finally up to 20% of cases result in amputation. The most important factor resulting in severe complications or even death is lack of self-care. Health locus of control has been introduced as one of health factors and predicting factors of self-care. This research was performed for analyzing the correlation between self-care behaviors and health locus of control in diabetic foot patients. In this descriptive study, 120 patients with diabetic foot were chosen using convenience sampling from endocrine clinic and wards of endocrine and vascular surgery of Teleqani Hospital of Shahid Beheshti Medical University. The data were gathered by demographic, self-care behavior, and health locus of control questionnaires. The t-test, analysis of variance (ANOVA) and spearman coefficient were used to analyze the data. RESULTS of this research showed that there is a direct and significant relation between selfcare behaviors and internal health locus of control (plocus of control (plocus of control improve and strengthen patients' self-care behaviors and their involvement in treatment.

    In species with duplicated major histocompatibility complex (MHC) genes, estimates of genetic variation often rely on multilocus measures of diversity. It is possible that such measures might not always detect more detailed patterns of selection at individual loci. Here, we describe a method that allows us to investigate classical MHC diversity in red jungle fowl (Gallus gallus), the wild ancestor of the domestic chicken, using a single locus approach. This is possible due to the well-characterised gene organisation of the 'minimal essential' MHC (BF/BL region) of the domestic chicken, which comprises two differentially expressed duplicated class I (BF) and two class II B (BLB) genes. Using a combination of reference strand-mediated conformation analysis, cloning and sequencing, we identify nine BF and ten BLB alleles in a captive population of jungle fowl. We show that six BF and five BLB alleles are from the more highly expressed locus of each gene, BF2 and BLB2, respectively. An excess of non-synonymous substitutions across the jungle fowl BF/BL region suggests that diversifying selection has acted on this population. Importantly, single locus screening reveals that the strength of selection is greatest on the highly expressed BF2 locus. This is the first time that a population of red jungle fowl has been typed at the MHC region, laying the basis for further research into the underlying processes acting to maintain MHC diversity in this and other species.

    To assess personality disorder (PD), emotional intelligence (EI), and locus of control of alcohol dependent (AD) patients and its comparison with normal controls. Based on purposive sampling technique, 33 AD patients were selected from the De-Addiction Ward of Ranchi Institute of Neuro-Psychiatry and Allied Sciences (RINPAS) and 33 matched normal subjects were selected from Ranchi and nearby places. Both the groups were matched on various sociodemographic parameters, that is, age, gender, and socioeconomic level. All participants were assessed with Millon Clinical Multiaxial Inventory-III, Mangal EI Inventory, and Locus of Control scale. Obtained responses were scored by using standard scoring procedures and subsequently statistically analyzed by using Chi-square test. AD patients have more comorbid pathological personality traits and disorders in comparison to their normal counterparts. Depressive, narcissistic, and paranoid PDs were prominent among AD group; followed by schizotypal, antisocial, negativistic, dependent, schizoid, sadistic, masochistic, and borderline PD. In comparison to normal participants, AD patients were significantly deficient in almost all the areas of EI and their locus of control was externally oriented. Patients with AD have significantly higher PDs, low EI, and an external orientation on the locus of control. Identification and management of these comorbid conditions are likely to improve the management and outcome of AD.

    Assuming that suicide is the result of a series of factors acting cumulatively, the aim of this paper was to study the association of self-esteem, resilience and locus of control with the risk of suicidal behavior in a sample of nursing students. Observational, cross-sectional and correlational study with 186 nursing students who answered a questionnaire that contained, in addition to demographic data, the Spanish forms of Rosenberg self-esteem scale, the brief resilient coping scale, the Plutchik scale of suicide risk and the Rotter's internal-external locus of control scale. The scores of males and females are very similar on all scales except Locus of Control, where a significantly greater tendency of females attributed to external control. 6.4% of students have scores indicating suicide risk. Suicide risk scores correlated negatively and significantly with self-esteem and resilience and positively with locus of control. The multiple linear regression analysis identified self-esteem as the main variable related to suicide risk. The results suggest that students who have low self-esteem, have difficulty in adjusting to adverse situations and tend to the external attribution of the consequences of their actions may have an increased risk of suicidal behavior. Furthermore, the identification of self-esteem as the important factor involved in suicide risk can help in designing prevention programs. Copyright © 2016 Elsevier España, S.L.U.

    This study investigated the relationship between locus of control and chosen field of music specialization. The Nowicki-Strickland Locus of Control Scale was designed to assess the construct of locus of control and reinforcement, which is defined as the perception of a connection between one's action and its consequences; the version of the scale used in this study was specifically developed and validated for use with college-aged students by Nowicki (2000). This scale was administered to four separate college-aged groups: music therapy majors, music education majors, applied music majors, and nonmusic majors who also had previous music background and were currently enrolled in a formal college music performance organization. Results indicated that there were indeed, differences among these populations with music therapy majors evidencing a significantly lower internal locus of control. Music education majors and nonmajors evidenced a greater internal level and were not significantly different from each other, yet both were significantly different from the music therapy majors. Music performance majors were also significantly lower in internal control compared to the music education and nonmusic majors, but they were not significantly different from the music therapy majors. This entire line of research has a long history and seems advisable to continue with all music populations, especially potential music therapists in order to investigate those aspects of self-perception that may help or hinder therapeutic effectiveness.

    To determine the Persian version's reliability and validity of the Multidimensional Health Locus of Control and God Health Locus of Control scales among women with family history of breast cancer. The cross-sectional study was conducted in Sabzevar, Iran, in 2012. It randomly selected women with family members affected by breast cancer. Predesigned questionnaires were completed through interviews. Content and face validity was evaluated using the opinions of a panel of experts, and construct validity was confirmed by applying confirmatory factor analysis.The instruments' reliability was assessed using Cronbach's alpha and test-retest reliability. There were 200 women in the study with their age ranging between 18 and 69 years and revealed the following; root mean square error of approximation for Multidimensional Health Locus of Control Scale = 0.013, and God Locus of Health Control Scale = 0.077; comparative fit index = 0.999, 0.998; incremental fit index = 0.999, 0.998;Tucker-Lewis fit index = 0.998, 0.998; and normed fit index = 0.983, 0.997 respectively. Cronbach's alpha was 0.61 for Internal Health Locus of Control, 0.8 for Chance Health Locus of Control, 0.68 for Power Health Locus of Control and 0.9 for God Locus Health Control. The Persian version of the subscales supported the main version.

    Several evidences indicate that the locus coeruleus (LC) is involved in central chemoreception responding to CO 2 /pH and displaying a high percentage of chemosensitive neurons (>80%). However, there are no studies about the LC-mediated hypercapnic ventilation performed in females. Therefore, we assessed the role of noradrenergic LC neurons in non-ovariectomized (NOVX), ovariectomized (OVX) and estradiol (E2)-treated ovariectomized (OVX+E2) rats in respiratory response to hypercapnia, using a 6-hydroxydopamine (6-OHDA) - lesion model. A reduction in the number of tyrosine hydroxylase (TH) immunoreactive neurons (51-90% in 3 animals of NOVX group, 20-42% of lesion in 5 animals of NOVX females, 61.3% for OVX and 62.6% for OVX+E2 group) was observed seven days after microinjection of 6-OHDA in the LC. The chemical lesion of the LC resulted in decreased respiratory frequency under normocapnic conditions in OVX and OVX+E2 group. Hypercapnia increased ventilation in all groups as consequence of increases in respiratory frequency (fR) and tidal volume (V T ). Nevertheless, the hypercapnic ventilatory response was significantly decreased in 6-OHDA-NOVX>50% rats compared with SHAM-NOVX group and with females that had 20-42% of LC lesion. In OVX and OVX+E2 lesioned groups, no difference in CO 2 ventilatory response was observed when compared to SHAM-OVX and SHAM-OVX+E2 groups, respectively. Neither basal body temperature (Tb) nor Tb reduction in response to hypercapnia were affected by E2 treatment, ovariectomy or LC lesion. Thus, our data show that LC noradrenergic neurons seem to exert an excitatory role on the hypercapnic ventilatory response in female rats, as evidenced by the results in NOVX animals with LC lesioned more than 50%; however, this modulation is not observed in OVX and OVX+E2 rats. In addition, LC noradrenergic neurons of OVX females seem to provide a tonic excitatory drive to maintain breathing frequency in normocapnia, and this response may not to be

    2017-06-01

    This study examined the incidence of PTSD and psychiatric co-morbidity among women who experienced stillbirth and investigated the relationship between locus of control, trauma characteristics of stillbirth, posttraumatic cognitions, PTSD and co-morbid psychiatric symptoms following stillbirth. Fifty women recorded information on stillbirth experiences, and completed the Posttraumatic Stress Diagnostic Scale, General Health Questionnaire-28, Edinburgh Post-natal Depression Scale, Rotter's Locus of Control Scale and the Posttraumatic Cognitions Inventory. 60, 28 and 12 % met the diagnostic criteria for probable full-PTSD, partial and no-PTSD respectively. Sixty-two percent and 54 % scored at or above the cutoff of the General Health Questionnaire-28 and postnatal depression respectively. Women who experienced stillbirth reported significantly more psychiatric co-morbid and post-natal depressive symptoms than the comparison group. Both groups were similar in locus of control. Women who experienced stillbirth reported negative cognitions about the self the most. After adjusting for postnatal depression, trauma characteristics were significantly correlated with Posttraumatic cognitions which, in turn, were significantly correlated with PTSD and psychiatric co-morbidity. Locus of control was not significantly correlated with psychological outcomes. Mediational analyses showed that negative cognitions about self mediated the relationship between trauma characteristics and psychiatric co-morbidity only. Women reported a high incidence of probable PTSD and co-morbid psychiatric symptoms following stillbirth. Stillbirth trauma characteristics influenced how they negatively perceived themselves. This then specifically influenced general psychological problems rather than PTSD symptoms.

    The authors would like to thank Dr. Morisky for giving us permission to use the Morisky Medication Adherence Scale To explore caregivers' Health Locus of Control's relationship to self-reported adherence to penicillin prophylaxis or hydroxyurea in children with sickle cell disease (SCD). A questionnaire-based study was conducted of caregivers of children with SCD who visited a comprehensive sickle cell center in an inner city hospital, who were either on penicillin prophylaxis or hydroxyurea or both. Multidimensional Health Locus of Control Scale (MHLC) and the Morisky Medication Adherence Scale (MMAS-8) questionnaires were used for the study. Caregivers of 43 children (27 on penicillin prophylaxis, 13 on hydroxyurea, and 3 on both) completed the MHLC and the MMAS-8. There was no significant difference in adherence between the penicillin and the hydroxyurea groups. The mean Powerful Others score of caregivers of the hydroxyurea only group (25.5+5.6) was higher than that of the penicillin only group (21.2+6.1, p=0.043). Regression analysis revealed an inverse relationship of Chance Locus of Control to adherence in the entire group (Beta = -0.306, R2=0.093, F[1,40]=4.12, p=0.049). Chance Locus of control may identify caregivers of children with SCD at risk for non-adherence to treatment. © 2015 National Medical Association. Published by Elsevier Inc. All rights reserved.

    2006-01-01

    Full Text Available This paper deals with the relationship between some elements of self-concept (general self-esteem and locus of control and going in for sport in adolescence. The relationship between going in for sport and variables of self-concept (general self-esteem and external locus of control was investigated in a sample of 300 adolescent boys and girls (150 sportsmen and 150 non-sportsmen. Modification of the Rosenberg’s General self-esteem scale and Bezinović-Savčić’s Scale of externality were used to measure variables of self-concept. The significant positive correlation between variables of going in for sport and general selfesteem, as well as negative ones between variables of going in for sport and external locus of control were found in the whole sample of subjects and in the sample of boys, but not of girls. The sex role stereotypes and greater importance that the culture puts on success in sport for boys have contributed to such results. The sex differences in correlations between variables of self-concept and going in for sport suggest that going in for sport influences general self-esteem and locus of control in adolescents through social feedback and social evaluation of sport achievement and physical fitness. .

  16. Can Locus of Control Compensate for Socioeconomic Adversity in the Transition from School to Work?

    Science.gov (United States)

    Ng-Knight, Terry; Schoon, Ingrid

    2017-10-01

    Internal locus of control is associated with academic success and indicators of wellbeing in youth. There is however less understanding regarding the role of locus of control in shaping the transition from school to work beyond the more widely studied predictors of socioeconomic background and academic attainment. Guided by a socio-ecological model of agency, the current study examines to which extent internal locus of control, understood as an indicator of individual agency, can compensate for a lack of socioeconomic resources by moderating the association between parental disadvantage and difficulties in the transition from school to work. We draw on data collected from a longitudinal nationally representative cohort of 15,770 English youth (48% female) born in 1989/90, following their lives from age 14 to 20. The results suggest that the influence of agency is limited to situations where socioeconomic risk is not overpowering. While internal locus of control may help to compensate for background disadvantage regarding avoidance of economic inactivity and unemployment to some extent, it does not provide protection against long-term inactivity, i.e. more than 6 months spent not in education, employment or training.

    Full Text Available Background: Job burnout is an occupational hazard that reduces physical and mental energy of the staff. This study was aimed to investigate the relationship between the nurses' job burnout and their social responsibility considering the moderating role of control locus. Methods: In an analytical and cross-sectional study we used 3 valid questionnaires including Maslach burnout inventory, Dynson social responsibility and Rotter locus of control in 3 educational hospitals of Yazd, Iran. A total of 246 nurses contributed in the study. Data analysis was done through SPSS19. We used Pearson and Kendall correlation coefficient in data analysis. Findings: The mean scores of job burnout and social responsibility of studied group were 60.75 +8.37 and 71.84+15.47, respectively. Job burnout is negatively correlated with social responsibility statistically (r= -0.250 while locus of control acts as the moderator of this correlation. Conclusion: Our results suggest that creating a supportive work environment for nurses enhances their social responsibility trough affecting their level of job burnout. Also, the approved moderating role of control locus in the relationship of job burnout and social responsibility indicates that the personality traits can be considered as the appropriate criteria for entry to nursing schools.

    The objectives of this study were to assess the relationship between Locus of Control (LoC) and oral health among a group of rural adolescent school children and to examine the influence of socioeconomic status (SES) on the association between health, LoC and oral health status. A total of 318 children 15 years of age from a public and private school formed the study population. The children were administered following the Indian translation of the 18-item Multidimensional Health Locus of Control scale, and subsequently examined for caries and oral hygiene. T tests and correlation analyses showed a significant relationship between higher 'Internal' Locus of Control and dental caries. A hierarchical multiple regression analysis was performed to assess the effect of socioeconomic status on LoC and oral health using three interaction models which showed a statistically significant interaction between 'Internal' LoC and socioeconomic status on caries. Socioeconomic stratum-specific estimates of the relationship between the LoC and caries revealed a positive association between Internal LoC and caries in the middle socioeconomic group. The results demonstrated the relationship between Locus of Control and oral health, and the role of socioeconomic status having a strong bearing on this relationship.

    Among individuals residing in the United States, the Internet is the third most used source for obtaining health information. Little is known, however, about its use by Latinas. To understand health-related Internet use among Latinas, the authors examined it within the theoretical frameworks of health locus of control and acculturation. The authors predicted that acculturation would serve as a mediator between health locus of control and health-related Internet use, age and health-related Internet use, income and health-related Internet use, and education and health-related Internet use. Data were collected via a 25-minute self-report questionnaire. The sample consisted of 932 young (M age = 21.27 years), low-income Latinas. Using structural equation modeling, the authors observed that acculturation partially mediated the relation between health locus of control and health-related Internet use and fully mediated the relations among age, income, and Internet use. An internal health locus of control (p income (p Internet use. The Internet is a powerful tool that can be used to effectively disseminate information to Latinas with limited access to health care professionals. These findings can inform the design of Internet-based health information dissemination studies targeting Latinas.

    2014-10-01

    Coalescent-based species delimitation methods combine population genetic and phylogenetic theory to provide an objective means for delineating evolutionarily significant units of diversity. The generalised mixed Yule coalescent (GMYC) and the Poisson tree process (PTP) are methods that use ultrametric (GMYC or PTP) or non-ultrametric (PTP) gene trees as input, intended for use mostly with single-locus data such as DNA barcodes. Here, we assess how robust the GMYC and PTP are to different phylogenetic reconstruction and branch smoothing methods. We reconstruct over 400 ultrametric trees using up to 30 different combinations of phylogenetic and smoothing methods and perform over 2000 separate species delimitation analyses across 16 empirical data sets. We then assess how variable diversity estimates are, in terms of richness and identity, with respect to species delimitation, phylogenetic and smoothing methods. The PTP method generally generates diversity estimates that are more robust to different phylogenetic methods. The GMYC is more sensitive, but provides consistent estimates for BEAST trees. The lower consistency of GMYC estimates is likely a result of differences among gene trees introduced by the smoothing step. Unresolved nodes (real anomalies or methodological artefacts) affect both GMYC and PTP estimates, but have a greater effect on GMYC estimates. Branch smoothing is a difficult step and perhaps an underappreciated source of bias that may be widespread among studies of diversity and diversification. Nevertheless, careful choice of phylogenetic method does produce equivalent PTP and GMYC diversity estimates. We recommend simultaneous use of the PTP model with any model-based gene tree (e.g. RAxML) and GMYC approaches with BEAST trees for obtaining species hypotheses.

  10. A novel high-resolution single locus sequence typing scheme for mixed populations of Propionibacterium acnes in vivo.

    Directory of Open Access Journals (Sweden)

    Christian F P Scholz

    Full Text Available The Gram-positive anaerobic bacterium Propionibacterium acnes is a prevalent member of the normal skin microbiota of human adults. In addition to its suspected role in acne vulgaris it is involved in a variety of opportunistic infections. Multi-locus sequence-typing (MLST schemes identified distinct phylotypes associated with health and disease. Being based on 8 to 9 house-keeping genes these MLST schemes have a high discriminatory power, but their application is time- and cost-intensive. Here we describe a single-locus sequence typing (SLST scheme for P. acnes. The target locus was identified with a genome mining approach that took advantage of the availability of representative genome sequences of all known phylotypes of P. acnes. We applied this SLST on a collection of 188 P. acnes strains and demonstrated a resolution comparable to that of existing MLST schemes. Phylogenetic analysis applied to the SLST locus resulted in clustering patterns identical to a reference tree based on core genome sequences. We further demonstrate that SLST can be applied to detect multiple phylotypes in complex microbial communities by a metagenomic pyrosequencing approach. The described SLST strategy may be applied to any bacterial species with a basically clonal population structure to achieve easy typing and mapping of multiple phylotypes in complex microbiotas.

    Oil palm breeding has been progressing very well in Southeast Asia, especially in Malaysia and Indonesia. Despite this progress, there are still problems due to the difficulty of controlled crossing in oil palm. Contaminated/illegitimate progeny has appeared in some breeding programs; late and failure of detection by the traditional method causes a waste of time and labor. The use of molecular markers improves the integrity of breeding programs in perennial crops such as oil palm. Four half-sib families with a total of 200 progeny were used in this study. Thirty polymorphic single locus DNA microsatellites markers were typed to identify the illegitimate individuals and to obtain the correct parental and progeny assignments by using the CERVUS and COLONY programs. Three illegitimate palms (1.5%) were found, and 16 loci proved to be sufficient for sibship assignments without parental genotypes by using the COLONY program. The pairwise-likelihood score (PLS) method was better for half-sib family assignments than the full likelihood (FL) method.

    This paper describes some basics for the root locus controls design method as well as for loop shaping, and establishes approaches to expedite the application of these two design methodologies to easily obtain control designs that meet requirements with superior performance. The two design approaches are compared for their ability to meet control design specifications and for ease of application using control design examples. These approaches are also compared with traditional Proportional Integral Derivative (PID) control in order to demonstrate the limitations of PID control. Robustness of these designs is covered as it pertains to these control methodologies and for the example problems.

    Empirical researches have proved that there are powerful correlations between dependent personality and depression. Different hypotheses were described to conceptualize links between these two entities. The dysfunction of attributive style seems to be linked to dependency and to depression. Interpersonal dependency can be considered to be a mode of adaptation to the external direction of the locus of control. The self-esteem so subjected to the climate of social interactions can lead, by the discontinuity of its protective relations, to the depression. In a coordinated model, this study explores psychopathological aspects between depressive cognition, self-esteem and interpersonal dependency. This study tries to support the hypothesis that depression and dependency are consequences of an external locus of control, secondary in deterioration of the self-esteem and the main objective is to highlight correlations between external locus of control, interpersonal dependency, hopelessness and depressive affect. The regrouping of 42 patients in a protocol of psychotherapeutic practices allowed the realization of this retrospective study, multicentric within different hospitals or ambulant psychiatric structures of the agglomeration of Lille, during a period of 6 months. The administration of questionnaires (Beck Depression Inventory/Dependent Personality Questionnaire by Tyrer, translated by Loas/Hopelessness Scale by Beck/Powerful others and Chance Scale [IPC] of Levenson, translated by Loas) was included into clinical practice. The main results indicate that external locus of control "powerful others" is significantly correlated with pathological dependency (Plocus "chance" (Plocus "powerful others" (Plocus of control as a psychopathologic component between depression and dependent personality. This cognitive aspect manifests vulnerability in the depression of the patients suffering from pathological dependency. Also, the place of external locus of control ("powerful

    The primary objective of this paper was to integrate two research traditions, social cognition approach and individual state approach, and to understand the relationships between locus of control (LOC), risk perception, flight time, and safety operation behavior (SOB) among Chinese airline pilots. The study sample consisted of 193 commercial airline pilots from China Southern Airlines Ltd. The results showed that internal locus of control directly affected pilot safety operation behavior. Risk perception seemed to mediate the relationship between locus of control and safety operation behaviors, and total flight time moderated internal locus of control. Thus, locus of control primarily influences safety operation behavior indirectly by affecting risk perception. The total effect of internal locus of control on safety behaviors is larger than that of external locus of control. Furthermore, the safety benefit of flight experience is more pronounced among pilots with high internal loci of control in the early and middle flight building stages. Practical implications for aviation safety and directions for future research are also discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

    This study integrates healthy ageing and health psychology theories to explore the mechanisms underlying the relationship between health control expectancies and age-attitudes on the process of ageing well. Specifically, the aim of this study is to investigate the relationship between age-stereotypes and health locus of control. A population-based survey of 739 adults aged 20-97 years (mean = 57.3 years, SD = 13.66; 42% female) explored attitudes towards ageing and health attitudes. A path-analytical approach was used to investigate moderating effects of age and gender. Higher age-stereotype endorsement was associated with higher chance (β = 2.91, p controlling for age, gender, education and self-rated health. Significant age and gender interactions were found to influence the relationship between age-stereotypes and internal health locus of control. Our findings suggest that the relationship between age-stereotypes and health locus of control dimensions must be considered within the context of age and gender. The findings point to the importance of targeting health promotion and interventions through addressing negative age-attitudes.

    To compare locus of control and coping strategies in older persons with and without depression. This cross-sectional study included 144 depressed in-patients from seven psychogeriatric hospital units, and 106 community-dwelling older persons without depression. All participants were 60 years and older. Locus of control was assessed by a 17-items self-report questionnaire with six response categories. Coping strategies were assessed by a 26-items self-report questionnaire with five response categories. For analytical purposes, age (controlling for demographics, health, and social variables, the depressed in-patients showed a higher external locus of control orientation and a less frequent use of problem-focused coping strategies compared with the non-depressed group. No differences in use of emotion-focused strategies were found between the two groups. Compared with the non-depressed old persons, the depressed hospitalized older persons were characterized by perceptions of less personal control, and less use of problem-focused strategies, what also might have brought positive alterations into their situation.

    To determine whether glycemic control in adults with either insulin-dependent diabetes mellitus (IDDM) or non-insulin-dependent diabetes mellitus (NIDDM) is related to perceived family function, stress/coping, affect, and locus of control. Cross-sectional, observational study. Four hundred seven subjects from a family medicine ambulatory care unit, a tertiary pediatric diabetic unit, or a public-funded community health center, all located in Winston-Salem, NC, completed a series of psychometric instruments that included the Family APGAR (Adaptation, Partnership, Growth, Affection, and Resolve), FACES III (Family Adaptability and Cohesion Evaluation Scales) Cohesion subscale, Affect Balance Scale, Multidimensional Health Locus of Control Scales, and the Brief Encounter Psychosocial Instrument. Glycemic control was measured by fasting blood glucose levels and glycosylated hemoglobin A1C levels as well as by patients' perception of their control. Those with NIDDM had scores indicative of more external sources of control than those with IDDM. A greater proportion of adults with both subtypes of diabetes perceived their families to be disengaged than subjects from families without diabetes. In a bivariate analysis, family dysfunction correlated with lack of perceived glycemic control, while perceived stress and negative affect correlated with fasting glucose levels in those with NIDDM but not those with IDDM. Using multivariate discriminant analysis, adults with NIDDM in good glycemic control as measured by glycosylated hemoglobin levels had lower family cohesion and negative affect than those in poor control. Conversely, those with IDDM with acceptable glycosylated hemoglobin levels had higher family cohesion, less negative affect, fewer chance loci of control, but higher perception of inadequate coping than those in poor control. Knowledge of the family function, affect, locus of control, perceived stress, and coping may be useful to the family physician in the care

    Internal locus of control is associated with better psychological outcomes in comparison with external locus of control. Individuals experiencing a psychotic episode have a more external orientation, an externalizing bias for negative events and associations between paranoid delusions and external locus of control. The concept of multidimensional locus of control as measured by the Multidimensional Health Locus of Control (MHLC) scale may provide important information about the nature and course of psychotic symptoms. This narrative review explored the relationship between the orientation of locus of control and psychosis. Few studies have used the scale in samples with people experiencing psychotic symptoms and so there is limited evidence about the psychometric properties of the MHLC scale within this client group, although the findings from studies that have explored the properties of this tool in other groups suggest it could be a valuable instrument for use in psychosis. Further research is required to determine both the relationship between locus of control and psychosis in terms of therapeutic factors and outcome, and also the veracity of the MHLC scale as an instrument of choice in this group. © 2014 John Wiley & Sons Ltd.

THREE METHODS WERE APPLIED: Multidimensional Health Locus of Control Scale by K.A. Wallston, B.S. Wallston and R. DeVellis; the Acceptance of Illness Scale by B.J. Felton, T.A. Revenson, and G.A. Hinrichsena; and a personal questionnaire. Two groups were subject to the research: 68 patients with Graves-Basedow disease and 54 patients with Hashimoto disease. Patients with Graves-Basedow disease, women above all, have their health locus of control in other persons (P = 0,001) and are less inclined to accept their illness (P = 0,005) when compared to patients with Hashimoto disease. A statistically significant correlation occurred between the age of patients and external (i.e., in other persons) health locus of control. Beliefs in health locus of control and type of illness in female patient group are predictors of illness acceptance (P = 0,0009).

    The study aimed to investigate the relationship among self concepts, health locus of control, cognitive functioning and health-promoting lifestyles in patients diagnosed with schizophrenia. We examined health-promoting lifestyles through self-efficacy, self-esteem, health locus of control and neurocognitive factors. Fifty-six people with schizophrenia were enrolled in the study group. All subjects participated in the self-esteem (Rosenberg Self-Esteem Scale), self-efficacy (General Self-Efficacy Scale), health locus of control (The Multidimensional Health Locus of Control Scales), health-promoting lifestyles (Health Promotion Life-style Profile-II) and a series of neurocognitive measures. Stepwise regression analysis revealed that self-efficacy, internal health locus of control and attentional set-shifting accounted for 42% of the variance in total health-promoting lifestyles scores. Self-efficacy, self-esteem, internal and powerful others health locus of control and attentional set-shifting were significant predictors for domains of health-promoting lifestyles, respectively. Study findings can help mental health professionals maintain and improve health-promoting behaviors through a better understanding of self-esteem, self-efficacy, health locus of control and neurocognitive functioning among people with schizophrenia.

    Responding to criticisms surrounding the structural validity of the higher order core self-evaluations (CSE) construct, in the current study we examined the appropriateness of including locus of control as an indicator of CSE. Drawing from both theoretical and empirical evidence, we argue that locus of control is more heavily influenced by evaluations of the environment compared with the other CSE traits. Using data from 4 samples, we demonstrate that model fit for the higher order CSE construct is better when locus of control is excluded versus included as a trait indicator and that the shared variance between locus of control and CSE is nominal. This does not mean that locus of control is irrelevant for CSE theory though. We propose that evaluations of the environment moderate the relations that CSE has with its outcomes. To test this proposition, we collected data from 4 unique samples that included a mix of student and employee participants, self- and other-ratings, and cross-sectional and longitudinal data. Our results revealed that locus of control moderated relations of CSE with life and job satisfaction, and supervisor-rated job performance. CSE had stronger, positive relations with these outcomes when locus of control is internal versus external. These findings broaden CSE theory by demonstrating one way in which evaluations of the environment interface with evaluations of the self.

    HIV/AIDS knowledge has been rated as the most important factor for HIV prevention. However, studies have also shown that knowledge alone does not always translate into reduced risky sexual behavior (RSB). Health locus of control (HLC) categorized as perceived control over health status (internal locus of control) or attribution of health status to chance or fate (external health locus of control) is a psychological construct that has been shown to impact health outcomes including RSB. This study thus investigated the relationship between HLC and RSB among Nigerian adolescents. A cross-sectional survey design was employed among 361 adolescents from nine senior secondary schools selected through stratified random sampling from Jos, Plateau State Nigeria. Data were collected between August and October of 2008. Health Locus of Control Scale was used to categorize individuals into having either an internal or external HLC. RSB was assessed using the Brief HIV Screener (BHS). Descriptive statistics were computed and Mann-Whitney U test was used to determine differences in BHS scores by HLC categories. Odds ratios and adjusted odds ratios were calculated for individual BHS question responses based on HLC. Participants were 169 males (46.8%) and 192 females (53.2%) with a mean age of 16.9. When grouped into HLC categories, 141 were internal and 220 were external. The mean score on the BHS showed statistically significant difference based on HLC (p=0.01). Odds for using a condom during sexual intercourse were higher for adolescents with an internal HLC while adolescents with an external HLC had significantly higher RSB scores. Prevention programs targeted at adolescents should also aim to internalize their HLC.

    Cancer patients need to trust their oncologist. How the oncologist communicates probably contributes to patients' trust. Yet, patient characteristics such as their attachment style and health locus of control may influence how such communication is perceived. We examined how these personality characteristics influence trust as well as moderate the relation between oncologist communication and trust. Eight videotaped scenarios of an oncologic consultation were created. Oncologist communication was systematically varied regarding their expressed competence, honesty and caring. Cancer patients (n = 345) were randomly assigned to view the videos and report their trust in the observed oncologist. Patients' self-reported attachment style, health locus of control and trust in their own oncologist were assessed. Patients with a stronger external health locus of control trusted the observed oncologist more (p communication of caring and honesty on trust: avoidant attachment significantly diminished the effect (p style influences how oncologist communication influences trust, underscoring the importance of oncologists tailoring their communication to individual patients. We confirmed observational findings that patients convinced that others control their health trust their oncologist more than others. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Given that waste generation is an economic and environmental problem for nations and governments, it is necessary that we advance our knowledge on the etiology of waste prevention behaviours. This study aimed to investigate about the relationships between the locus of control, hardiness, emotional intelligence, and waste prevention behaviours. Four hundred and forty participants (226 females and 214 males from Universiti Putra Malaysia completed a survey questionnaire. Structural Equation Modeling (SEM estimated that individuals who were high in emotional intelligence and hardiness showed better waste prevention behaviours as well as those individuals with internal locus of control. Also, the results showed that older students tend to have better waste prevention behaviours. These findings reinforce the importance of personality traits and emotional intelligence in waste prevention behaviours.

    Due to high prevalence and serious impacts, childhood caries represents a public health issue. Behavioural risk factors such as locus of health control have been implicated in the development of the disease; however their association with childhood caries has not been thoroughly studied. The aim of this cross-sectional survey was to assess the relationship between parental locus of health control and caries experience and untreated caries of their preschool children in a representative sample in Czech Republic, adjusting for relevant sociodemographic characteristics. A representative sample of 285 preschool children and their parents was recruited. Study data included children's dental status recorded in nurseries and parental questionnaires with 13 attitudinal items regarding locus of control (LoC) in caries prevention. The association between parental locus of control and children's caries experience and level of untreated caries was analysed using logistic regression, adjusting for the effect of key sociodemographic variables. There was a statistically highly significant linear trend between increased parental LoC and higher probability of the children to be free from untreated caries, independent from the effect of sociodemographic variables of children and parents. A similar highly statistically significant trend, although not entirely linear, and independent from sociodemographic variables was observed with respect to the chance of the children to be free from caries experience with increasing strength of parental LoC. After full adjustment, children in the strongest parental LoC quintile were 2.81 (1.23-6.42, pcontrol of both untreated caries and caries experience in their preschool children and highlight that a more internal LoC within the family is advantageous in the prevention of dental caries.

    Most studies about coping in pregnancy focus on risk pregnancies where it has generally been found that the use of religious coping has a positive effect, although to our knowledge there are no studies that associate religious coping to locus of control. We analyzed, in a sample of 285 Spanish women with normal pregnancies, the effect of both variables on psychiatric symptoms and on the relationship between psychiatric symptoms and pregnancy worries. The results show no association between locus of control and religious coping. Locus of control has a significant influence on the pregnant women's mental health, while religious coping just adds an additional influence.

    Carter, Larry W; Mollen, Debra; Smith, Nathan Grant

    2014-01-01

    Within the framework of minority stress theory, lesbian, gay, and bisexual (LGB) individuals are conceptualized as members of a minority group defined by sexual orientation. Two of the component processes of minority stress hypothesized by Meyer (2003), internalized heterosexism and the experience of prejudice events, were examined in the current study. Both internalized heterosexism and the experience of prejudice events have been associated with increased psychological distress in LGB populations. Researchers have also observed a relationship between external locus of control and increased psychological distress in general population samples. The current study explored whether locus of control served as a moderator in the relationship between the overall psychological distress of LGB individuals and both internalized heterosexism and the experience of workplace-based prejudice events (n = 165). Results indicated that locus of control served as a moderator in the relationship between experience of workplace-based prejudice events and overall psychological distress but not for the relationship between internalized heterosexism and distress.

  10. Motivating contributions to online forums: can locus of control moderate the effects of interface cues?

    Science.gov (United States)

    Kim, Hyang-Sook; Sundar, S Shyam

    2016-01-01

    In an effort to encourage users to participate rather than lurk, online health forums provide authority badges (e.g., guru) to frequent contributors and popularity indicators (e.g., number of views) to their postings. Studies have shown the latter to be more effective, implying that bulletin-board users are motivated by external validation of their contributions. However, no consideration has yet been given to individual differences in the influence of such popularity indicators. Personality psychology suggests that individuals with external, rather than internal, locus of control are more likely to be other-directed and therefore more likely to be motivated by interface cues showing the bandwagon effect of their online posts. We investigate this hypothesis by analyzing data from a 2 (high vs. low authority cue) × 2 (strong vs. weak bandwagon cue) experiment with an online health community. Results show that strong bandwagon cues promote sense of community among users with internal, rather than external, locus of control. When bandwagon cues are weak, bestowal of high authority serves to heighten their sense of agency. Contrary to prediction, weak bandwagon cues appear to promote sense of community and sense of agency among those with external locus of control. Theoretical and practical implications are discussed.

    Although the two medaka species Oryzias latipes and O. curvinotus share the sex-determining gene Dmy, XY sex reversal occurs in interspecific hybridization between O. latipes females of the Hd-rR inbred strain and O. curvinotus males. In this Hd-rR-curvinotus mating, all XX and XY hybrids developed as females. In this study, we used another O. latipes inbred strain (HNI) for the mating, and found that 23% of XY hybrids developed as males, although all XX and the remaining XY hybrids developed as females. Linkage analysis using 236 XY hybrid males obtained from (Hd-rR × HNI) F(1) females showed that a single major locus, Hybrid maleless (Hml), on autosomal linkage group 17, contributed to the strain difference in the XY sex reversal. Furthermore, we found that crossing females of a different O. latipes inbred strain, HO4C, did not cause XY sex reversal in the interspecific hybrids, and that the XY hybrids from (Hd-rR × HO4C) F(1) females showed a 1:1 sex ratio. XY hybrid males had the HO4C allele at sequence-tagged site loci around the Hml locus whereas XY females had the Hd-rR allele, confirming the strong contribution of this locus to XY sex reversal. Reverse transcriptase PCR analysis showed a reduced expression of Dmy(curvinotus) in XY fry of the Hd-rR-curvinotus hybrids at hatching. These results suggest that the Hd-rR allele at the Hml locus interfere with the function of Dmy(curvinotus) on a hybrid background, thus resulting in XY sex reversal.

  13. Single-Locus versus Multilocus Patterns of Local Adaptation to Climate in Eastern White Pine (Pinus strobus, Pinaceae.

    Directory of Open Access Journals (Sweden)

    Om P Rajora

    Full Text Available Natural plant populations are often adapted to their local climate and environmental conditions, and populations of forest trees offer some of the best examples of this pattern. However, little empirical work has focused on the relative contribution of single-locus versus multilocus effects to the genetic architecture of local adaptation in plants/forest trees. Here, we employ eastern white pine (Pinus strobus to test the hypothesis that it is the inter-genic effects that primarily drive climate-induced local adaptation. The genetic structure of 29 range-wide natural populations of eastern white pine was determined in relation to local climatic factors using both a reference set of SSR markers, and SNPs located in candidate genes putatively involved in adaptive response to climate. Comparisons were made between marker sets using standard single-locus outlier analysis, single-locus and multilocus environment association analyses and a novel implementation of Population Graphs. Magnitudes of population structure were similar between the two marker sets. Outlier loci consistent with diversifying selection were rare for both SNPs and SSRs. However, genetic distances based on the multilocus among population covariances (cGD were significantly more correlated to climate, even after correcting for spatial effects, for SNPs as compared to SSRs. Coalescent simulations confirmed that the differences in mutation rates between SSRs and SNPs did not affect the topologies of the Population Graphs, and hence values of cGD and their correlations with associated climate variables. We conclude that the multilocus covariances among populations primarily reflect adaptation to local climate and environment in eastern white pine. This result highlights the complexity of the genetic architecture of adaptive traits, as well as the need to consider multilocus effects in studies of local adaptation.

    2016-10-01

    Full Text Available Background The belief that an individual can influence and control the course of events is a factor which enables a person to overcome difficulties. Some studies, however, have questioned the universality of this statement. This study aims to investigate and explore the relationship between the self-health locus of control and the effectiveness of cooperation in the treatment process in adolescents with chronic diseases. Participants and procedure One hundred and sixty-four adolescent patients suffering from chronic diseases (61 girls and 103 boys ranging from 11 to 17 years old participated in the study. Eighty-seven had primary hypertension and 77 had type 1 diabetes. To investigate their sense of health control we used the Health Locus of Control Scale (HLC. Cooperation in the treatment process was assessed using a 4-item scale completed by a doctor. Results Better results in the treatment were positively correlated with a better internal health locus of control. A negative correlation between the chance health locus of control and results in the treatment was found. Differences in the health locus of control proved to be dependent on gender, age and different clinical groups. Conclusions Health locus of control in patients with chronic diseases seems to be a crucial factor in determining the results of the treatment process in such patients.

    The term emetophobia (i.e., a fear of vomiting) exists as rather an elusive predicament, often eluding conventional treatment. The present study involved 149 participants, consisting of 51 emetophobics, 48 phobic controls (i.e. those who suffered from a different phobia), and 50 nonphobic controls. Participants were administered the Rotter (1966) Locus of Control Scale and the Health Locus of Control Scale by B.S. Wallston, Wallston, Kaplan, and Maides (1976). Significant differences were found among the three groups; specifically, that emetophobics had a significantly higher internal Locus of Control Scale score with regard to both general and health-related issues than did the two control groups. It is suggested that vomiting phobics may have a fear of losing control, and that their vomiting phobia is reflective of this alternative, underlying problem. More research is required to explore the association between emetophobia and issues surrounding control; however, the current study suggests that it may be helpful for therapists to consider this aspect when treating a patient with vomiting phobia.

    We investigated the relationship between three factors--internal/external locus of control, self-esteem, and parental verbal interaction--for at-risk Black male adolescents in the United States. Forty-two male students in Grades 6, 7, and 8 who had been identified by their teachers as being at risk completed the Locus of Control Scale for Children (Nowicki & Strickland, 1973), the Self-Esteem Inventory (Coopersmith, 1967), and the Verbal Interaction Questionnaire (Blake, 1991). A moderate positive relationship found between self-esteem and parental verbal interaction was consistent with a previous finding for White high school students. A moderate negative relationship found between locus of control and self-esteem differed from a previous finding of no significant relationship for Black elementary children. A weak, yet significant, negative relationship was found between locus of control and parental verbal interaction.

    The present study examined job stress and job satisfaction and their relation to measures of neuroticism, Type A behavior, and I-E locus of control as well as sex differences among Kuwaiti men (n= 189) and women (n = 210) employees. Women had significantly higher means on scales of job stress, neuroticism, and external locus of control, while men scored significantly higher on job satisfaction. Analysis yielded significant and positive correlations of job stress with neuroticism and locus of control of both men and women. Job satisfacrion scores correlated significantly but negatively with external locus of control for both sexes, while job satisfaction had a positive correlation with Type A behavior for women only. The significant correlation between job stress and job satisfaction was negative.

    Little is known about the influence of control beliefs on antiretroviral drug adherence in patients who migrated from sub-Saharan Africa to Europe. The aim of this study was to explore the differences in health locus of control and control beliefs between HIV infected patients from sub-Saharan Africa with and without a lifetime experience of migration. A sample of 62 HIV infected consecutive patients referred to the HIV clinics at the University Hospital of Münster (Germany) and at the Rubaga Hospital Kampala (Uganda) were enrolled into this study. We compared three groups of patients: sub-Saharan African migrants, German patients, and local Ugandan patients. We used the German health and illness related control beliefs questionnaire (KKG), the Competence and control beliefs questionnaire (FKK), and the Powe Fatalism Inventory-HIV/AIDS-Version (PFI-HIV/AIDS-Version) and translated these scales into English and Luganda. In addition, the patients' sociodemographic, acculturation, clinical, and immunological data were registered. Significant results were shown in HIV related external locus of control between migrated sub-Saharan African and local Ugandan patients compared to German patients. General control beliefs showed no significant differences. In the PFI-HIV-Version, there was a significant difference between migrated sub-Saharan African and Ugandan patients compared to German patients. Our data suggest that the experience of migration does not influence the locus of control. Compared to German HIV patients, African patients in general showed a significantly higher external health locus of control which might have implications for drug adherence.

    Many plant, animal, and fungal genomes contain cytosine DNA methylation in asymmetric sequence contexts (CpHpH, H = A, T, C). Although the enzymes responsible for this methylation are unknown, it has been assumed that asymmetric methylation is maintained by the persistent activity of de novo methyltransferases (enzymes capable of methylating previously unmodified DNA). We recently reported that the DOMAINS REARRANGED METHYLASE (DRM) genes are required for de novo DNA methylation in Arabidopsis thaliana because drm1 drm2 double mutants lack the de novo methylation normally associated with transgene silencing. In this study, we have used bisulfite sequencing and Southern blot analysis to examine the role of the DRM loci in the maintenance of asymmetric methylation. At some loci, drm1 drm2 double mutants eliminated all asymmetric methylation. However, at the SUPERMAN locus, asymmetric methylation was only completely abolished in drm1 drm2 chromomethylase 3 (cmt3) triple mutant plants. drm1 drm2 double mutants also showed a strong reduction of CpNpG (n = A, T, C, or G) methylation at some loci, but not at others. The drm1 drm2 cmt3 triple mutant plants did not affect CpG methylation at any locus tested, suggesting that the primary CpG methylases are encoded by the MET1 class of genes. Although neither the drm1 drm2 double mutants nor the cmt3 single mutants show morphological defects, drm1 drm2 cmt3 triple mutant plants show pleiotropic effects on plant development. Our results suggest that the DRM and CMT3 genes act in a partially redundant and locus-specific manner to control asymmetric and CpNpG methylation.

  1. Targeted transgenesis at the HPRT locus: an efficient strategy to achieve tightly controlled in vivo conditional expression with the tet system.

    The tet-inducible system has been widely used to achieve conditional gene expression in genetically modified mice. To alleviate the frequent difficulties associated with recovery of relevant transgenic founders, we tested whether a controlled strategy of transgenesis would support reliable cell-specific, doxycycline (Dox)-controlled transgene expression in vivo. Taking advantage of the potent hypoxanthine-aminopterin-thymidine selection strategy and an embryonic stem (ES) cell line supporting efficient germ-line transmission, we used hypoxanthine phosphoribosyltransferase (HPRT) targeting to insert a single copy tet-inducible construct designed to allow both glucocorticoid receptor (GR) and beta-galactosidase (beta-Gal) expression. Conditional, Dox-dependent GR and beta-Gal expression was evidenced in targeted ES cells. Breeding ES-derived single copy transgenic mice with mice bearing appropriate tet transactivators resulted in beta-Gal expression both qualitatively and quantitatively similar to that observed in mice with random integration of the same construct. Interestingly, GR expression in mice was dependent on transgene orientation in the HPRT locus while embryonic stem cell expression was not. Thus, a conditional construct inserted in single copy and in predetermined orientation at the HPRT locus demonstrated a Dox-dependent gene expression phenotype in adult mice suggesting that controlled insertion of tet-inducible constructs at the HPRT locus can provide an efficient alternative strategy to reproducibly generate animal models with tetracycline-induced transgene expression.

    This descriptive study used quantitative and qualitative methods to gain a deeper understanding of the perceptions of locus of control and the academic success of baccalaureate nursing students from ethnically diverse backgrounds. Students who were more likely to attribute academic outcomes to forces beyond their personal control were more likely to have lower medical-surgical theory grades, more likely to be Filipino or from other Asian groups, and more likely to be students for whom English was their second language. The most frequently reported factors students identified as contributors to academic success were good study strategies, persistence, and supportive social connections.

    To investigate the relationship between the healthy lifestyle behaviors and the health locus of control and health-specific self-efficacy in university students. The study included 572 undergraduate students of a university in the central Anatolia region of Turkey. The data were collected with the General Characteristics Form, the Health-Promoting Lifestyle Profile II, the Multidimensional Health Locus of Control Scale, and the Perceived Health Competence Scale and investigated with the structural equation model. Health-specific self-efficacy was an important predictor of healthy lifestyle behaviors. The Internal health locus of control influenced the healthy lifestyle behaviors through health-specific self-efficacy. The other dimension was the Powerful Others health locus of control that affected healthy lifestyle behaviors, both directly and indirectly, through health-specific self-efficacy. There was a chance that the health locus of control had a negative effect on healthy lifestyle behaviors through self-efficacy. Health-specific self-efficacy is an important prerequisite for changes in healthy lifestyle behaviors, which supports Pender's model. The subscales of the health locus of control vary in their effects on healthy lifestyle behaviors, which partly supports Pender's model. Nurses, by using this model, can examine ways of improving these cognitive-perceptual factors and implement health education programs that are directed towards improving them in young persons. © 2016 Japan Academy of Nursing Science.

    The main objective of this study was to investigate the mediating role of uncertainty in the relationship between locus of control with quality of life, anxiety, and depression. A descriptive and correlational survey was conducted in a private hospital in Kuala Lumpur, Malaysia. A convenience sample of 118 Malaysian breast cancer patients voluntarily participated in the study and responded to a set of questionnaires including: socio-demographic questionnaire, the short form of Locus of Control Scale, the Functional Assessment of Cancer Therapy-Breast (FACT-B), the Hospital Anxiety and Depression Scale (HADS), and the Short-Form Mishel Uncertainty in Illness Scale (SF-MUIS). The results revealed that breast cancer patients with higher internal locus of control and lower external locus of control experience a higher quality of life, lower anxiety, and lower depression. Also, uncertainty mediated the relationship between locus of control with quality of life and depression (quasi-significant). The findings indicated the need for early, targeted psychological interventions seeking to gradually shift cancer patients' locus of control from external to internal in order to improve their quality of life and reduce their depression and anxiety. Moreover, health care providers by providing relevant information to cancer patients, especially for externally oriented patients, can reduce their uncertainty which in turn would improve their quality of life.

    To identify the relationship and behaviour of the variables of self-control, self-efficacy and locus control in weight regulation of obese, overweight and normal weight adults. Transversal study undertaken in the Health Centre of El Coto (Gijón) from 1st April to 30th July 2015. Subjects between 18-65 years of age with a body mass index recording within the last two years. serious medical illness, eating disorders or pregnant women. Behavioural variables: self-regulation of body weight (Inventory of self-control of body weight), perceived self-efficacy in weight regulation (Inventory of perceived self-efficacy in weight regulation) and locus control in weight regulation (Inventory of locus control in weight regulation). Anthropometric variables: weight (kg) and height (m), body mass index. One hundred and six participants were included: 32 were obese, 28 overweight and 46 normal weight. Significant differences were found between the 3 study groups for total scale of self-efficacy (F=61.77; p<.01), total scale of self-regulation (F=45.97; p<.01), internal locus control (F=13.92; p=.019), other weighty influences of locus control (F=9.21; p<.01) and random locus control (F=3.50; p=.011). The relationship between body mass index and behavioural variables of self-efficacy, self-regulation and locus control, suggests the need for healthcare professionals to include psychological factors of behaviour in any preventive action and intervention directed at weight control.

    An effective preceptor is a vital component of a strong learning experience for learners. Many clinical preceptors provide on-site supervision and clinical teaching but lack the skills necessary to be effective teachers. Few studies have examined the factors related to teaching competence among clinical nurse preceptors. This article is a report of a study that examined (a) the differences in teaching competence by preceptor background, (b) the influence of locus of control on self-evaluated teaching competence, (c) the association between self-directed learning and self-evaluated teaching competence, and (d) the predictors of self-evaluated teaching competence among clinical nurse preceptors. This descriptive and correlational study used a cross-sectional survey of a convenience sample of 243 clinical nurse preceptors from a medical center in northern Taiwan. Of these, 242 completed questionnaires for an effective response rate of 99.6%. The self-evaluated Teaching Competencies Scale, Internal-External Scale, and Self-Directed Learning Instrument were used to assess teaching competencies and related factors among clinical nurse preceptors. Descriptive statistics, one-way ANOVA, Mann-Whitney test, and multivariate linear regression were used to analyze data. Clinical nurse preceptors averaged 4.03 in teaching competence, indicating a moderately above average score. Higher teaching competence was associated with older age, being married, >10-year work experience, not assigned by unit manager, and good internal locus of control. Self-directed learning significantly correlated with teaching competence (r = .62). Internal locus of control and self-directed learning were significant independent predictors of teaching competence after adjusting for age, marital status, total years as a clinical nurse preceptor, and willingness to be a clinical nurse preceptor. Together, these accounted for 33.6% of teaching competence variance. Nurse managers should recognize all factors

      The incidence of Healthcare Associated Infections (HAI) is an important indicator of the quality of care. The behaviors associated with the prevention of infections are not only supported by rational knowledge or motivation, but are mediated by social, emotional and often stereotyped behaviors. The awarness of the good practices related to HAI, may be a factor. Other studies, identify how the perception of the problem in healthcare professionals is often influenced by a tendency towards an external Locus of Control: the patient, the family, the other wards, other care settings. The aim of this study is to investigate the perception of healthcare professionals. In particular they have been measured their  awarness of the good practices, perceptions of the potential contamination level of some commonly used objects, knowledge about the management of invasive devices, Locus of Control.   A cross-sectional correlational design was utilized.  An ad hoc questionnaire was interviewed by 222 health professionals nurses and physicians in a northern hospital of Italy. The percentage of professionals who have attended training courses over the last 5 years was quite high, both for upgrades on HAI (78.7%) and Vascular Catheters (78.8%), while the percentage of professionals who updated on bladder catheterization (59.46%) was lower. The mean  score of good practice awareness towards HAI (5.06), is high. The perception of the potential level of contamination of some devices had a  mean ranging from 4.62 (for the drip) to 5.26 (for the door handle). The average value of the Locus of Control (43.54) indicates that participants demonstrated a value that is midway between External and Internal. The correlation test analysis revealed no significant relationships among professionals'age, knowledge about HAI, or infection related venus catheter. Also, results revealed that there were statistically significant positive relationships between professionals' Good Practices

    Few instruments have been translated and validated for people who use American Sign Language (ASL) as their preferred language. This study examined the reliability and validity of a new ASL version of the widely-used Multidimensional Health Locus of Control (MHLC) scales. Deaf individuals (N = 311) were shown the ASL version via videotape, and their responses were recorded. Confirmatory factor analysis supported the four-factor structure of the MHLC. Scale reliabilities (Cronbach’s alphas) ranged from .60 to .93. There were no apparent gender or ethnic differences. These results provide support for the new ASL version of the MHLC scales.

  20. Who Do You Think Is in Control in Addiction? A Pilot Study on Drug-related Locus of Control Beliefs.

    2012-12-01

    The drug-related locus of control scale (DR-LOC) is a new instrument for assessing a person's belief of "being in control" in situations involving drug abuse. It consists of 16-item pairs presented in a forced-choice format, based on the conceptual model outlined by Rotter. The model characterizes the extent to which a person believes that the outcome of an event is under their personal control (internal locus of control) or the influence of external circumstances (external locus of control). A total of 592 volunteers completed the DR-LOC and the Rotter's I-E scale. Approximately half of the respondents were enrolled in a drug treatment program for opiates, stimulants and/or alcohol dependence (n = 282), and the remainder (n = 310) had no history of drug dependence. Factor analysis of DR-LOC items revealed 2 factors reflecting control beliefs regarding (i) the successful recovery from addiction, and (ii) decisions to use drugs. The extent to which a person attributes control in drug-related situations is significantly influenced by their personal or professional experiences with drug addiction. Drug-dependent individuals have a greater internal sense of control with regard to addiction recovery or drug-taking behaviors than health professionals and/or non-dependent control volunteers. The DR-LOC has shown to effectively translate generalized expectancies of control into a measure of control expectancies for drug-related situations, making it more sensitive for drug-dependent individuals than Rotter's I-E scale. Further research is needed to demonstrate its performance at discriminating between heterogeneous clinical groups such as between treatment-seeking versus non-treatment-seeking drug users.

  1. Are measures of self-esteem, neuroticism, locus of control, and generalized self-efficacy indicators of a common core construct?

    Judge, Timothy A; Erez, Amir; Bono, Joyce E; Thoresen, Carl J

    2002-09-01

    The authors present results of 4 studies that seek to determine the discriminant and incremental validity of the 3 most widely studied traits in psychology-self-esteem, neuroticism, and locus of control-along with a 4th, closely related trait-generalized self-efficacy. Meta-analytic results indicated that measures of the 4 traits were strongly related. Results also demonstrated that a single factor explained the relationships among measures of the 4 traits. The 4 trait measures display relatively poor discriminant validity, and each accounted for little incremental variance in predicting external criteria relative to the higher order construct. In light of these results, the authors suggest that measures purporting to assess self-esteem, locus of control, neuroticism, and generalized self-efficacy may be markers of the same higher order concept.

On the basis of evidence for strong links between locus of control orientation and attitudes, an attempt was made to enhance internality through instruction.A quasiexperimental research strategy was employed to compare the effects of two instructional treatments, with pretest measures being used to check the initial equivalence of treatment groups, and analysis of covariance (ANCOVA) being used to test treatment effects. Both treatments incorporated strategies known to have positive effects on attitudes, but the experimental treatment was novel in its emphasis on self-management, goal clarification, and individualized course expectations.There was found by ANCOVA to be a significant (p 0.05) difference in science locus of control (SciLOC) orientation between groups following treatment, with subjects exposed to the experimental treatment exhibiting greater internality. Quantitative comprehension and subject age were employed as covariates of SciLOC orientation, and subject gender was employed as a moderator variable. Though the treatment effect is small, accounting for 3% of the variance in SciLOC orientation, control orientation is shown susceptible to educational intervention. These results encourage attention to teacher attitudes from a rather new perspective, and they raise several interesting research questions regarding instructional methods and the long-term effects of enhancing internality.

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

    The primary aim of this study was to evaluate whether school maladjustment longitudinally predicts the daytime sleepiness of college students with ADHD above and beyond symptoms of ADHD and to determine whether internalizing dimensions mediate the relationship between maladjustment and sleepiness. A prospective longitudinal study of 59 college students comprehensively diagnosed with ADHD who completed ratings at the beginning, middle, and end of the school year. School maladjustment at the beginning of the year significantly predicted daytime sleepiness at the end of the year above and beyond symptoms of ADHD. Locus of control mediated the relationship between maladjustment and daytime sleepiness. The significant school maladjustment difficulties that students with ADHD experience following the transition to college may lead to the development of problems with daytime sleepiness, particularly for those students with high external locus of control. This pattern is likely reciprocal, whereby sleep problems in turn result in greater school impairment, reinforcing the idea that life events are outside of one's control. © The Author(s) 2014.

    Locus of Control research has established that college students are becoming more external, and that internality is preferable. If an external locus of control is associated with poor self-esteem, alienation, depression, and "burn out" in nurses as it is with other individuals, then we need to reverse this trend. Lefcourt (1976) tells us that in the future, methods fostering internality will be crucial. Toffler (1980) says that to break out of the rigid mentality of the Second Wave, future-oriented nurses must be self-responsible. Self-responsible, internally controlled practitioners will enable themselves and the nursing profession to grow as they will anticipate and participate in the selection of the knowledge, skills, and characteristics they need to grow. The purpose of this study was to determine if a course which explores the transition into a futuristic-oriented professional nursing role would move registered nurse students in a baccalaureate program toward stronger internality. A basic pretest-intervention-post test experimental design was used and results of an analysis of covariance significantly determined the efficacy of the course in encouraging greater internality, F (3,60) = 49.55, p less than .0001.

    Full Text Available Objective: To assess the health locus of control, spirituality and hope of cure in patients with intestinal stoma. Methods: This study was conducted at the Polo of Ostomized People in the city of Pouso Alegre, Minas Gerais. Participants were 52 patients with intestinal stoma. Three questionnaires were applied for data collection: a questionnaire on demographic and stoma-related data; the Scale for Health Locus of Control; the Herth Hope Scale, and the Self-rating Scale for Spirituality. Results: Most ostomized subjects were women aged over 61 years, married and retired. As to the stoma, in the majority of cases these operations were definitive and were carried out due to a diagnosis of neoplasia. Most ostomized subjects had a 20- to 40-mm diameter colostomy, 27 showed dermatitis as a complication, and 39 (75% used a two-part device. The mean total score for the Scale for Health Locus of Control, the Herth Hope Scale, and the Self-rating Scale for Spirituality were 62.42, 38.27, and 23.67, respectively. Regarding the dimensions of the Scale for Health Locus of Control, the dimension “completeness of health” = 22.48, dimension “externality-powerful others” = 22.48, and dimension “health externality” = 19.48. Conclusion: Ostomized patients participating in the study believe they can control their health and that caregivers and individuals involved in their rehabilitation can contribute to their improvement. The cure or improvement has a divine influence through religious practices or beliefs.

    Thirty female anorectics (mean age 26.4) and 30 female college student controls (mean age 25.3) completed a multidimensional locus of control scale, the Structural Family Interaction Scale, The Eating Attitudes Test, and a global clinical assessment measure. Three variables associated with Minuchin, Rosman, and Baker's (1978) family systems theory (overprotection, enmeshment, and rigidity) and one related to Bruch's (1973) theoretical position on anorexia nervosa (locus of control) were contrasted in terms of their relative effectiveness in predicting both the presence or absence and severity of the disorder. The best predictor of both measures in a series of regression and discriminant function analyses was locus of control orientation. The anorectics were significantly more external than the controls. The two groups did not differ on any of the family variables central to Minuchin et al.'s theory. The results support Bruch's contention that underlying anorexia nervosa is a sense of personal ineffectiveness.

    Full Text Available While considerable research has examined the academic and cognitive value of journaling, little has examined the psychological impact of journaling on the personal development of college students. Research on cognitive-behavioral therapy indicates that journaling can have a positive impact on individuals’ self-growth and intrapersonal characteristics. The purpose of this study is to examine the impact of classroom-based journaling on students’ self-efficacy and locus of control. Students in two undergraduate courses were required to complete weekly journal assignments; one class received targeted information on cognitive-behavioral therapy (CBT and one class did not. Students completed pre-, mid-, and postcourse assessments on self-efficacy, locus of control, and learning. Results revealed that self-efficacy scores for both groups significantly improved after the early journaling assignments; however, there were no differences between those who received direct CBT instruction and those who did not. These findings indicate that journaling may have important psychological benefits above and beyond its expected academic and cognitive outcomes.

    The core objective of the present work is to explore the reasons why workers from different employment sectors join training courses to improve their job. To this end we assessed achievement motivation, locus of control and professional qualifications according to the participants' employment sector. The final sample consisted of 1460 active Spanish workers from four different employment sectors: services, catering, metal construction, and others. Of the sample, 40.1% were male and 59.9% female, with a mean age of 33.3 years (SD = 9.7). The results show that the new scale developed to assess achievement motivation, locus of control and workers' qualifications presents adequate psychometric characteristics. Statistically significant differences were found in relation to employment sector. The areas studied showed satisfactory levels of workers' effort and achievement motivation to perform their jobs, though their attitudes toward the training courses as a basis for improving their employability are varied. Workers in the catering sector had higher levels of external attribution and the lowest interest in training. Those in the service sector had higher levels of achievement motivation and effort at work. Future research should develop a joint program covering the public and private sectors for the modification of these beliefs, attitudes and attributions.

  12. Hybrid Sterility Locus on Chromosome X Controls Meiotic Recombination Rate in Mouse.

    Full Text Available Meiotic recombination safeguards proper segregation of homologous chromosomes into gametes, affects genetic variation within species, and contributes to meiotic chromosome recognition, pairing and synapsis. The Prdm9 gene has a dual role, it controls meiotic recombination by determining the genomic position of crossover hotspots and, in infertile hybrids of house mouse subspecies Mus m. musculus (Mmm and Mus m. domesticus (Mmd, it further functions as the major hybrid sterility gene. In the latter role Prdm9 interacts with the hybrid sterility X 2 (Hstx2 genomic locus on Chromosome X (Chr X by a still unknown mechanism. Here we investigated the meiotic recombination rate at the genome-wide level and its possible relation to hybrid sterility. Using immunofluorescence microscopy we quantified the foci of MLH1 DNA mismatch repair protein, the cytological counterparts of reciprocal crossovers, in a panel of inter-subspecific chromosome substitution strains. Two autosomes, Chr 7 and Chr 11, significantly modified the meiotic recombination rate, yet the strongest modifier, designated meiotic recombination 1, Meir1, emerged in the 4.7 Mb Hstx2 genomic locus on Chr X. The male-limited transgressive effect of Meir1 on recombination rate parallels the male-limited transgressive role of Hstx2 in hybrid male sterility. Thus, both genetic factors, the Prdm9 gene and the Hstx2/Meir1 genomic locus, indicate a link between meiotic recombination and hybrid sterility. A strong female-specific modifier of meiotic recombination rate with the effect opposite to Meir1 was localized on Chr X, distally to Meir1. Mapping Meir1 to a narrow candidate interval on Chr X is an important first step towards positional cloning of the respective gene(s responsible for variation in the global recombination rate between closely related mouse subspecies.

    Self-esteem and behavioral consequences, which are due to external or internal locus of control, are effective on academic achievement of students. The aim of this study was to determine the prediction of locus of control and self-esteem in academic achievement among the students. This cross-sectional study was conducted on 300 college students in Kermanshah University of Medical Sciences in 2014. Data collection tools were in three sections: demographic, Rotter internal-external locus of control scale and Coopersmith self-esteem inventory. Data were analyzed using the SPSS software version 21. Results showed that 29.8% and 76.2% of the participants had internal locus of control, and high self-esteem, respectively. There was a significant correlation between self-esteem, locus of control and academic achievement of the students. Self-esteem accounted for 39.5% of the variation in academic achievement. It seems that interventions to increase self-esteem among student can help improve academic achievement among them.

    To investigate the effects of disposition (locus of control, optimism, and depression) on recollections of cognitive functioning following cancer treatment. Participants were survivors of colorectal cancer (n = 88) and their spouses (n = 40). Survivors retrospectively rated their cognitive functioning and depression, as experienced following treatment and currently rated their dispositions for optimism and locus of control. Survivors' spouses likewise provided their recollections of survivors' cognitive functioning and depression at time following treatment. Correlations between survivors' and spouses' ratings for cognitive functioning were statistically significant but not for depression. Results supported validity of survivors' longer term retrospective reports. Although internal locus of control correlated positively with retrospectively self-reported cognitive functioning, and negatively with retrospectively self-reported depression, moderated hierarchical multiple regression found independent contribution of internal locus of control was limited to predicting quality of life; and that, among variables tested, depression correlated strongest with cognitive functioning. Neither internal locus of control nor optimism in colorectal cancer survivors influences correlation between cognition and depression. Health care providers should note individual differences in responses to treatment and be alert to the impact of depression on perceived everyday functioning.

    The present prospectively designed 15-year longitudinal research was conducted to study whether locus of control is linked to diagnosis, to major symptoms, to functioning and recovery, and to personality for schizophrenia patients, depressive patients, and patients with other major disorders. The research studied 128 patients from the Chicago Follow-up Study at the acute phase and reassessed them 5 times over a 15-year period. Patients were evaluated on locus of control, global outcome, recovery, premorbid developmental achievements, psychosis, diagnosis, depression, and personality variables. 1) After the acute phase, schizophrenia patients were not more external than other diagnostic groups. 2) Internality is significantly associated with increased recovery in schizophrenia. 3) A more external locus of control was significantly related to depression. 4) The relationship between externality and psychosis was significant. In severe psychiatric disorders a more external locus of control is not specific to schizophrenia and after the acute phase is not associated with one particular diagnostic group. A more external locus of control is significantly related to fewer periods of recovery, to both depressed mood and psychosis, and to various aspects of personality.

    Medication adherence is an important determinant of disease outcomes, yet medication use on average tends to be low among patients with chronic conditions, including asthma. Although several predictors of non-adherence have been assessed, more research is needed on patients' beliefs about God and how these relate to medication use. To examine the relationship between perceptions about "God's" role in health and other locus of control factors with inhaled corticosteroid (ICS) adherence among asthma patients. Participants were from a clinical trial to improve ICS adherence and were 5-56 years old, had a diagnosis of asthma, and were receiving ICS medication. Baseline adherence was estimated from electronic prescription and pharmacy fill records. Patients were considered to be adherent if ICS use was ≥80% of prescribed. A baseline survey with the Multidimensional Health Locus of Control scale was used to assess five sources (God, doctors, other people, chance, and internal). Medication adherence was low (36%). Patients' who had a stronger belief that God determined asthma control were less likely to be adherent (odds ratio [OR] 0.82, 95% confidence interval [CI] 0.70-0.96). This relationship was stronger among African American (OR 0.68, 95% CI0.47-0.99) compared to white patients (OR 0.89, 95% CI 0.75-1.04), and among adults (OR 0.81, 95% CI 0.69-0.96) compared to children (OR 0.84, 95% CI 0.58-1.22). Patients' belief in God's control of health appears to be a factor in asthma controller use, and therefore should be considered in physician-patient discussions concerning course of treatment.

    To determine the relations between household material hardships and having a low internal locus of control over the prevention of child obesity in low-income Hispanic pregnant women. We performed a cross-sectional analysis of baseline data collected during a third trimester prenatal visit from women participating in the Starting Early Study, a randomized controlled trial to test the efficacy of a primary care-based family-centered early child obesity prevention intervention. Using multiple logistic regression analyses, we determined whether 4 domains of material hardship (food insecurity, difficulty paying bills, housing disrepair, neighborhood stress), considered individually and also cumulatively, were associated with having a low internal locus of control over the prevention of child obesity. The sample included 559 low-income Hispanic pregnant women, with 60% having experienced at least 1 hardship. Food insecurity was independently associated with a low internal locus of control over the prevention of child obesity (adjusted odds ratio, 2.38; 95% confidence interval, 1.50-3.77), controlling for other hardships and confounders. Experiencing a greater number of material hardships was associated in a dose-dependent relationship with an increased odds of having a low internal locus of control. Prenatal material hardships, in particular food insecurity, were associated with having a lower prenatal internal locus of control over the prevention of child obesity. Longitudinal follow-up of this cohort is needed to determine how relations between material hardships and having a low internal locus of control will ultimately affect infant feeding practices and child weight trajectories.

    In this research, we wanted to clarify how gender images are different or invariant and related to parents, attributes, and the attitude of controlling life (locus of control) in two cultural contexts, Japan and Finland. For this purpose, students' ideal gender images, consisting of ideal mother, female, father and male images, and parents' similarity to the four ideal gender images were studied in 135 Japanese and 119 Finnish university students. Major findings were (a) Japanese students' ideal gender images were more stereotypic than those of Finnish students; (b) students' ideal mother image and parents' similarity to the ideal mother image were related only to their sex, which supports Jung's theory; (c) students socially learned other ideal gender images, but these did not fit with expectation from social learning theory; (d) Japanese students' mothers are models or examples of gender images, but Finnish male students did not seem to base their ideal gender images on their parents. Implication of measures was discussed.

This parameter can be associated with medication adherence, in addition to other psychosocial factors that may also influence this behavior. This study was performed to investigate the influence of the LPC on medication adherence in patients undergoing an orthopedic procedure. Subjects and methods: We conducted a prospective cohort study on patients who attended an orthopedic clinic for arthroscopy treatment. The patients’ LPC and pain intensity data were obtained on the day of admission through the use of the LPC scale and the visual analog scale (VAS, respectively, both being validated tools. After arthroscopic surgery, the patients received drug prescriptions and were reassessed after 15 days regarding treatment adherence, using the Morisky test. A P-value <0.05 was considered statistically significant. Results: We assessed 79 individuals from both the internal LPC group (n=35 and external LPC group (n=44 and found that there were no group differences in sex, affected limb, cause of injury, repetitive strain injury, duration of pain, or pain intensity. However, there was a higher proportion of patients in the external LPC group that adhered to the prescribed medication compared with the internal LPC group (P>0.01. Conclusion: The results showed that among patients who underwent an orthopedic procedure, there was a higher adherence rate to prescribed medication in the external LPC group compared with the internal LPC group.Keywords: behavior, locus of control

    Health locus of control is a measure of an individual's beliefs in factors that are thought to determine health experiences. Scores are generated and form a graduated linear scale from external to internal control, with respect to their views on health causality. Health locus of control has been considered to be a relatively stable entity. However, it is not clear if this status changes in the advent of serious health challenges, such as coronary artery bypass graft surgery. The aim of this study is to explore the variability of health locus of control and its association with postoperative health in this context. In a longitudinal cohort study of patients undergoing coronary artery bypass graft surgery, a purposive sample ( n=215) were recruited from the waiting list and followed up postoperatively, at approximately one year and seven years later. Patients undergoing coronary artery bypass graft surgery demonstrated marked fluctuations in health locus of control in their peri-operative and rehabilitative phases. Mean health locus of control became more external (often associated with poorer outcomes) peri-operatively, and more internal (generally associated with better health outcomes) in the rehabilitative period. Health locus of control scores were shown to be changeable during a major health care intervention, with possible consequences for patient outcomes and care needs. The significant health belief upheaval demonstrated in this cohort should be considered in assessing patients preoperatively, and managed as part of the patients' clinical journey by both acute and rehabilitation staff. It is likely to have particular importance in individualised assessment and management of future prevention advice for patients.

    The aim of our study was to investigate the relationship between information needs and cancer patients' perceptions of the impact of the disease, self-efficacy, and locus of control. Using a standardized questionnaire, we obtained data from patients who attended a series of lectures. The questionnaire included questions on their information needs, sources of information, satisfaction with information, and short questionnaires on self-efficacy, perception of the disease, and locus of control of reinforcement. Data was obtained from 185 patients. Our results showed that the sources of information that were most often used were physicians (84 %), print media (68 %), and the Internet (59 %); online fora (7.5 %), non-medical practitioners (9.7 %), and telephone-based counseling (8.6 %) were only used by a minority. Patients with a high perception of their own control over the disease more often used any source of information available to them and were more often interested in acquiring additional information. Higher self-efficacy was significantly associated with the need for information on all topics. Patients with a higher external locus of control significantly more often used sources of information and had significantly more need for additional information. By contrast, there were no associations with an internal locus of control. Neither external nor internal locus of control showed any associations with satisfaction with information. Information needs seem to be higher in patients with a high external locus of control and low self-efficacy. Physicians, other professionals, and institutions that provide information may take these relationships into consideration for tailoring their services to patients.

    The association of 9p21.3 locus single nucleotide polymorphisms with arterial ischemic stroke in adults was demonstrated in many studies, but there are no studies in pediatric arterial ischemic stroke patients. We investigated whether the 9p21.3 locus polymorphism, namely rs10757278, is associated with the arterial ischemic stroke risk in children. The study group consisted of 335 individuals: 80 children with arterial ischemic stroke, their biological parents (n = 122), and 133 children (age and sex matched) without any symptoms of arterial ischemic stroke as a control group. The rs10757278 polymorphism was genotyped using the TaqMan® Pre-designed SNP Genotyping Assay (Applied Biosystems). Two different study design models were used: family-based association test (transmission-disequilibrium test) and case-control model. There were no statistically significant differences in the distribution of genotypes and alleles of the rs10757278 polymorphism between groups of children with arterial ischemic stroke and controls. The frequency of both transmitted alleles in transmission-disequilibrium test analysis was identical (50%). The A allele carrier state (AA+AG genotype) was more frequent in arterial ischemic stroke children with hemiparesis than in patients without this symptom (94.5% versus 68.0%, P = .004). There is no evidence to consider the 9p21.3 locus polymorphism as a risk factor for childhood arterial ischemic stroke. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    This study examines the relationship between educators' locus of control and job stress using samples from the US and Zimbabwe. Multiple regression analyses are used to identify significant relationships in the US sample between teachers' external locus of control and the severity of the job stress that they experience, coupled with the perceived degree of organisational support received. However, this relationship between the locus of control and stress indices could not be identified for the Zimbabwean sample. Significant differences between the two samples were noted in terms of educators' perceptions of the frequency of poor organisational support, with the Zimbabwean teachers reporting greater dissatisfaction. To explain these differences, a qualitative approach was utilised to illuminate the contextual stressors that educators face in Zimbabwe. The implications for teacher preparation measures are discussed.

    Prevention and treatment of the addictions are key public health priorities in modern society. In medical practice, in relation to the biochemical processes, mapping the addiction-prone personality traits, like external/internal locus of control are getting more and more attention. Individuals with high level on internal locus of control, for example, tend to take care of their health behavior; the lack of it, on the other hand, may worsen the effectiveness of stress release which may increase the likelihood of turning to substance use. The main goal of the present study was to investigate the relationship between adolescent substance use (both lifetime prevalence and the actual substance user status) and external/internal locus of control). The data collection of the questionnaire survey was going on among 656 high school students in Szeged (age range between 14-21 years, mean = 16.5 years, S.D. = 1.5 years of age, 49.1% of the sample was female). Associations between indicators of substance use (as dependent variables) and scale points of external/internal locus of control (as independent variables) were assessed using odds ratios calculated by logistic regression analyses, whereas gender was used as a controlling variable. Among boys, scale points of external, among girls, those of internal locus of control showed higher values. External locus of control increased, whereas internal locus of control decreased the risk of substance use, however, the relative role of external/internal locus of control was different according to the type of substance use and the prevalence values. In terms of smoking, lifetime prevalence, whereas in terms of marijuana use, the actual user status was influenced. In addition, while the latter one was also affected by gender, it did not play a role at all in the previous one. All these findings suggest that behavioral control may play a particularly important role in prevention of adolescent substance use. For developing this, methods

    In this paper, a new method for the calculation of all stabilizing PI controllers is given. The proposed method is based on plotting the stability boundary locus in the (k p , k i )-plane and then computing the stabilizing values of the parameters of a PI controller. The technique presented does not require sweeping over the parameters and also does not need linear programming to solve a set of inequalities. Thus it offers several important advantages over existing results obtained in this direction. Beyond stabilization, the method is used to shift all poles to a shifted half plane that guarantees a specified settling time of response. Computation of stabilizing PI controllers which achieve user specified gain and phase margins is studied. It is shown via an example that the stabilizing region in the (k p , k i )-plane is not always a convex set. The proposed method is also used to design PID controllers. The limiting values of a PID controller which stabilize a given system are obtained in the (k p , k i )-plane (k p , k d )-plane and (k i , k d )-plane. Furthermore, the proposed method is used to compute all the parameters of a PI controller which stabilize a control system with an interval plant family. Examples are given to show the benefits of the method presented

    Depression is an important health issue in cancer patients. People use different coping strategies and health locus of control to manage stressful situations, which relate to different risks of depression. Coping strategies and health locus of control can be changed by cognitive behavioral interventions. In a cohort study, we investigated differences in coping strategy and health locus of control in older (≥70 years) and middle-aged (50-69 years) cancer patients, and older patients without cancer (≥70 years), and their association with presence of depression. We also investigated how these factors interact. We used the short version of the Utrecht Coping List, the Multidimensional Health Locus of Control scale, and the 15-item Geriatric Depression Scale. Data were available from 1317 participants. Overall prevalence of depression was 12%. Older cancer patients tended to use an avoiding coping strategy more frequently than middle-aged cancer patients. This was associated with higher risk of depression. Older cancer patients less often used an active coping strategy, in comparison with middle-aged cancer patients, which was associated with a lower risk of depression. Especially in women using a seeking social support strategy, there was a lower risk of depression. Overall, the internal health locus of control was associated with higher and the external 'powerful others' locus with lower risk of depression. Older cancer patients strongly differ from middle-aged cancer patients, in particular with respect to coping. Interventions to prevent or alleviate depression should incorporate these differences.

    This study investigates the differences between adults with visual impairments and sighted adults with regard to locus of control (LOC) and self-esteem. One hundred and eight adults with visual impairments (blindness or low vision) and fifty-five sighted adults took part in this study. Sighted adults showed a higher score on the self-esteem scale than either the individuals with low vision or with blindness. Moreover, analysis indicated no significant differences amongst the three groups of participants regarding LOC. Significant predictors of self-esteem were vision status and age at loss of sight. Significant predictors of LOC were vision status and independent movement. Findings are discussed with regard to their implications for parents, social workers, teachers, and rehabilitation specialists. Copyright © 2013 Elsevier Ltd. All rights reserved.

    In a prospective longitudinal study the authors examined the associations between parent locus of control of reinforcement (LOCR), measured before the birth of a child, and behavioral-emotional outcomes in that child at age 7 years. A total of 307 couples completed questionnaires regarding their emotional status and LOCR at their first prenatal care appointment. When their children turned 7 years old, teachers completed questionnaires regarding each participating child's behavior. Findings indicate significant associations between fathers' prenatal LOCR and child outcomes, particularly hyperactivity in sons. Hyperactivity and behavioral-emotional problems in girls, in contrast, were better predicted by maternal prenatal emotional distress. Results provide evidence that paternal and maternal characteristics that predate the birth of a child relate to later behavioral outcomes in that child. Implications for prevention of child psychopathology are discussed.

    To determine the relationships of adherence to daily peak expiratory flow rate (PEFR) monitoring, recommended for asthma self-management, with self-concept and health locus of control in a sample of 42 children, ages 7 through 11. Secondary analysis was conducted on data collected as part of our 5-week randomized, controlled asthma self-management clinical trial. During the study, the Piers-Harris Children's Self-Concept Scale (PHCSC) and Children's Health Locus of Control Scale (CHLOC) were administered at baseline (Week 1) and Week 5 for comparison, while adherence to electronically-measured peak flow monitor (PFM) was evaluated during Week 5. Adherence was positively correlated with higher self-concept (r(s) = .33, p = .03) and internal health locus of control (r(s) = .30, p = .05). Adherence to PFM and the intellectual and anxiety subscales of the PHCSC also were positively associated (r(s) = .38, p = .01, in both cases). Children who have a positive self-concept, particularly in the areas of intellect and anxiety, are more adherent to their recommended asthma regimen. Similarly, those who perceive their ability to control their health more positively adhere better to daily PEFR monitoring. These results suggest that children's adherence interventions may need to include components aimed at enhancing self-concept and health locus of control.

    To assess the influence of health locus of control and fear of hypoglycaemia on metabolic control and treatment satisfaction in people with Type 1 diabetes mellitus on continuous subcutaneous insulin infusion. People with Type 1 diabetes on continuous subcutaneous insulin infusion for at least 1 year, sub-classified as an 'acceptable glucose control' group [HbA 1c ≤ 58 mmol/mol (7.5%)] and a 'suboptimum glucose control' group [HbA 1c > 58 mmol/mol (7.5%)], were consecutively enrolled in a multicentre cross-sectional study. Questionnaires were administered to assess health locus of control [Multidimensional Health Locus of Control (MHLC) scale, with internal and external subscales], fear of hypoglycaemia [Hypoglycaemia Fear Survey II (HFS-II)] and treatment satisfaction [Diabetes Treatment Satisfaction Questionnaire (DTSQ)]. We enrolled 214 participants (mean ± sd age 43.4 ± 12.1 years). The suboptimum glucose control group (n = 127) had lower mean ± sd internal MHLC and DTSQ scores than the acceptable glucose control group (19.6 ± 5.2 vs 21.0 ± 5.0, P = 0.04 and 28.8 ± 4.8 vs 30.9 ± 4.5, P locus represents the most important locus of control pattern for achieving good metabolic control. © 2017 Diabetes UK.

    To assess the effectiveness of application of health locus of control in pregnant women for prevention of postpartum depression in Iran. Nearly 10-15% of women suffer postnatal depression by the end of the second week after delivery, which creates problems in caring for the child that may affect child's future learning and concentration. Pre-post experimental design. Two hundred and thirty volunteer women were randomly divided into experimental and control groups. The data collection tools included a demographic questionnaire, the Multidimensional Health Locus of Control Scale and the Edinburg Depression Scale. Based on the associations found in the pretest, intervention programme was planned and carried out in the focused group discussion method. Data were collected after the end of scheduled sessions, immediately and one month later. The data were analysed with SPSS-16 using statistical methods including anova, chi-square test, Student's t-test and paired t-test. Chance health locus of control significantly reduced and internal health locus of control significantly increased, immediately after intervention. Also, a month after intervention, a significant difference was observed between the two groups in reducing postpartum depression. The planned participatory intervention led to empowerment and increased awareness and internalisation of health control beliefs and less tendency towards external health control beliefs, especially chance, improvement in general health leading to improved psychological health for prevention of postpartum depression in mothers. Clinicians might assess chance and internal health locus of control to identify the women at risk of developing depression during their pregnancy and to develop prevention and treatment plans. © 2013 John Wiley & Sons Ltd.

    This study presents the reported outcomes of a two-year, part-time Masters' programme in human relations using an experiential learning methodology based mainly on humanistic psychological theory. The following hypotheses were examined. That as a result of the two-year programme: the experience of reported stress would be reduced; reported attitudes to student classroom control would shift from custodial to humanistic; there would be an increase in reports from participants of a sense of control over their lives; changes of behaviour in work, social settings and at home related to these three variables would be reported. Involved in the study were 42 experienced teachers. These included 32 women and 10 men, with an average age of 35, who worked in a wide range of educational institutions. Their learning style preferences were also considered as independent variables. A control group of 42 was established with similar demographic characteristics. Prior to the course, the experimental group and the control group were given the Maslach Burnout Inventory and the Pupil Control Ideology Form. In the early stages of the course, the experimental group completed the Kolb Learning Style Inventory and an informal measure of locus of control which was repeated at the end of the first year of the course. A sample of 32 from the experimental group were given semi-structured interviews relating to changes in their professional and personal lives. The results indicated that, following the training, there was a reduction in reported stress, indications of a more humanistic orientation towards pupil control and an increase in a sense of an internal locus of control. The quantitative data were confirmed by qualitative data generated from semi-structured interviews, which involved substantial reports of applications of the training in their professional and personal lives. These results provide support for including experiential human relations training as part of both the in

    The unprecedented popularity of online communication has raised interests and concerns among the public as well as in scholarly circles. Online communications have pushed people farther away from one another. This study is a further examination of the effects of online communications on well-being, in particular: Locus of control, Loneliness, Subjective well-being, and Preference for online social interaction. Chinese undergraduate students (N = 260; 84 men, 176 women; M age = 20.1 yr., SD = 1.2) were questioned about demographic information and use of social media as well as four previously validated questionnaires related to well-being. Most participants used QQ, a popular social networking program, as the major channel for online social interactions. Locus of control was positively related to Loneliness and Preference for online social interaction, but negatively related to Subjective well-being; Loneliness (positively) and Subjective well-being (negatively) were related to Preference for online social interaction; and Loneliness and Subjective well-being had a full mediating effect between the relationships of Locus of control and Preference for online social interaction. The findings of the study showed that more lonely, unhappy, and externally controlled students were more likely to be engaged in online social interaction. Improving students' locus of control, loneliness, and happiness may help reduce problematic Internet use.

    As one of the most common cancers worldwide, breast cancer places an extraordinary burden on the populations of African ancestry. Common SNPs in the TERT-CLPTM1L locus have been reported to be associated with several types of cancer, including breast cancer. We sought to investigate whether the previously reported common single nucleotide polymorphisms (SNPs) in the TERT-CLPTM1L locus could also contribute to the breast cancer risk in women of African ancestry. We genotyped eleven SNPs in 2,892 women of African descent but were unable to detect any significant association between TERT-CLPTM1L SNPs and their predispositions for breast cancer risk. Given the differences in linkage disequilibrium patterns across populations, our findings suggest that larger independent studies from diverse populations are expected to evaluate the importance of the TERT-CLPTM1L locus in breast cancer.

    Preconception health programs have resulted in improved health behaviors among participants and have shown promise in reducing adverse birth outcomes. However, the role of health beliefs in preconception health program outcomes has been overlooked but warrants attention due to reported positive associations between women's views of control over fetal health and health behavior in pregnancy. Towards an ultimate aim of improving preconception health program reach and effectiveness, we examined properties of a fetal health locus of control (FHLC; Labs & Wurtele, 1986) measure in nulliparous, childbearing aged university women and men. Students (n=1467) completed an online survey that included the FHLC subscales maternal, powerful others', and chance control over fetal health. Factor analyses and correlations with related scales supported the soundness of FHLC constructs in both women and men. All participants rated maternal control in fetal health nearly twice as highly as powerful others' and chance. We therefore recommend that FHLC be integrated into preconception health program evaluation as personal agency in fetal health likely has an important role in women's and men's preconception health behavior and health behavior change.

    The current study utilizes Skinner's framework to examine the unique contributions of internal locus of control, self-efficacy, and perceived outcome control over course performance on students' academic experiences. Undergraduate students (N = 225) took part in a longitudinal study and completed two surveys (Time 1: just before their mid-term exams; Time 2: just before their final exam in the same semester). Both locus of control and self-efficacy at Time 1 predicted course-level perceived control over course performance at Time 2. Student-level perceived control over course performance at Time 2 mediated the relationship between self-efficacy at Time 1 and course-level perseverance, course-specific stress, and course enjoyment at Time 2. For global perceived stress and life satisfaction measured at Time 2, both locus of control and self-efficacy at Time 1 had only a direct effect on global perceived stress at Time 2, but only self-efficacy at Time 1 predicted life satisfaction at Time 2. Both locus of control and self-efficacy uniquely contribute to students' academic experiences. Student-level perceived control plays an important mediating role between locus of control and self-efficacy at Time 1, and course-level perseverance, course-specific stress, and course enjoyment at Time 2.

    Ethnic inequalities in health in Western societies are well-documented but poorly understood. We examined associations between health locus of control (HLC) and depressive symptoms among native and non-native Dutch people in the Netherlands. We used hierarchical multiple linear regression analyses on a representative sample of the multi-ethnic population of Amsterdam and The Hague (n = 10,302). HLC was measured with the multidimensional health locus of control scale. Depressive symptoms were measured with the Kessler Psychological Distress scale. Multivariate analyses showed that HLC contributes to ethnic differences in the prevalence of depressive symptoms. Respondents who scored high on external locus of control (PHLC) were more likely to have depressive symptoms than those with a low score on PHLC (β = 0.133, p locus of control (IHLC) were less likely to have depressive symptoms compared to those scoring low on IHLC (β = -0.134, p < 0.001). The associations were most pronounced among Turkish-Dutch and Moroccan-Dutch respondents. Our findings suggest that HLC contributes to ethnic inequalities in depressive symptoms, especially among Turkish and Moroccan ethnic groups. Professionals (e.g. clinicians and policy makers) need to take HLC into account when assessing and treating depression among ethnic minority groups, particularly in Turkish and Moroccan populations. Future research should look further into the associations within these groups.

    The present study sought to examine the interactive effects of an external locus of control and interaction in a negative peer group climate on men's perpetration of physical aggression and infliction of injury toward their female intimate partners. Participants were 206 heterosexual males recruited from the metro-Atlanta community who completed self-report measures of external locus of control, involvement in a negative peer group climate, and physical aggression and infliction of injury against intimate partners during the past 12 months. Negative peer group climate was conceptualized as a peer group that displays behavior which may instigate aggressive norms, attitudes, and behaviors. Results indicated that men with an external locus of control were more likely to perpetrate physical aggression toward and inflict injury on their intimate partners if they reported high, but not low, involvement in a negative peer group climate. These results extend current research suggesting external locus of control as a risk factor for intimate partner aggression by highlighting the impact of negative peer groups. Implications and future intervention research are discussed. © The Author(s) 2014.

    Health locus of control (HLC) has been associated with a variety of ailments and health outcomes and designed to predict behaviors and cognitive processes relevant to mental and physical health. This study investigated the relationships between perceived health locus of control, self-esteem, and mental health status among Iranian students. In this analytical study the subjects were recruited from students in Gonabad University of Medical Sciences, Iran, who studied in the first year (N=154). Students completed the questionnaires for assessing demographic, perceived health locus of control, self - esteem and psychological well- being data. The statistical analysis revealed a negative relationship between perceived Internal HLC and self-esteem with psychological well-being. The positive correlation of the perceived Chance HLC with psychological well-being was statistically significant (r= 0.21, Pself-esteem was statistically significant (r= 0.25, Plow perceived Internal HLC, self-esteem and psychological problems was found among these students. The findings will be addressed in relation to their implications for effective mental health education based on health locus of control especially internal and powerful others beliefs associated with self-esteem for students. This will require additional monitoring and uninterrupted trying in order to be effective.

    2010-08-01

    This study examined the influence of locus of control on disordered eating as mediated by the self-regulation of eating attitudes. The assessment instruments were adapted for athletes as the entire sample of 179 volunteer University students (M(age)=21.12; SD=2.87) were all regularly involved in competition. The results showed that (a) an internal locus of control had a positive influence on the self-regulation of eating attitudes in social interaction contexts; (b) self-regulatory eating attitudes had a negative influence on disordered eating in contexts of negative affect, social interaction, and lack of anticipation of consequences on performance; and (c) an internal locus of control had an influence on disordered eating through the mediation of self-regulatory eating attitudes in social interaction contexts, and an external locus of control attributed to the coach and sports friends had an influence on disordered eating through the mediation of self-regulatory eating attitudes in contexts of negative affect, social interaction and lack of anticipation of consequences on performance. This study, combined with an earlier study from Scoffier, Maïano, and d'Arripe-Longueville (2009) on the antecedents of athletes' eating disorders, suggests the powerful impact of the social environment on the development of disordered eating in athletes. 2010 Elsevier Ltd.

    Full Text Available Genotyping of Klebsiella pneumoniae is indispensable for management of nosocomial infections, monitoring of emerging strains--including extended-spectrum beta-lactamase (ESBL producers-, and general epidemiology. Such objectives require a high-resolution genotyping method with a fixed scheme that allows (1 long-term retrospective and prospective assessment, (2 objective result readout and (3 library storage for database development and exchangeable results. We have developed a multiple-locus variable number tandem repeat analysis (MLVA using a single-tube fluorescently primed multiplex PCR for 8 Variable Number Tandem Repeats (VNTRs and automated fragment size analysis. The type allocation scheme was optimized using 224 K. pneumoniae clinical isolates, which yielded 101 MLVA types. The method was compared to the gold standard multilocus sequence typing (MLST using a subset of these clinical isolates (n = 95 and found to be highly concordant, with at least as high a resolution but with considerably less hands-on time. Our results position this MLVA scheme as an appropriate, high-throughput and relatively low-cost tool for K. pneumoniae epidemiology.

  7. μ-Opioid receptor activation and noradrenaline transport inhibition by tapentadol in rat single locus coeruleus neurons.

    2015-01-01

    Tapentadol is a novel analgesic that combines moderate μ-opioid receptor agonism and noradrenaline reuptake inhibition in a single molecule. Both mechanisms of action are involved in producing analgesia; however, the potency and efficacy of tapentadol in individual neurons has not been characterized. Whole-cell patch-clamp recordings of G-protein-coupled inwardly rectifying K(+) (KIR 3.x) currents were made from rat locus coeruleus neurons in brain slices to investigate the potency and relative efficacy of tapentadol and compare its intrinsic activity with other clinically used opioids. Tapentadol showed agonist activity at μ receptors and was approximately six times less potent than morphine with respect to KIR 3.x current modulation. The intrinsic activity of tapentadol was lower than [Met]enkephalin, morphine and oxycodone, but higher than buprenorphine and pentazocine. Tapentadol inhibited the noradrenaline transporter (NAT) with potency similar to that at μ receptors. The interaction between these two mechanisms of action was additive in individual LC neurons. Tapentadol displays similar potency for both µ receptor activation and NAT inhibition in functioning neurons. The intrinsic activity of tapentadol at the μ receptor lies between that of buprenorphine and oxycodone, potentially explaining the favourable profile of side effects, related to μ receptors.

    Adherence to immunosuppressive medication is essential for favourable kidney transplant outcomes. The present study aims to investigate how self-efficacy beliefs, health locus of control and religiosity are associated with adherence to immunosuppressives in post kidney transplant recipients. This is a cross-sectional study with 88 recipients with more than 1 year after transplantation. Three methods were used to classify patients as adherent or non-adherent: Basel Assessment of Adherence Scale for Immunosuppressives - BAASIS, the collateral report and blood levels of immunosuppressive medications. Self-efficacy, health locus of control, and religiosity were evaluated applying General Perceived Self-Efficacy Scale, Multidimensional Health Locus of Control Scale and Duke University Religion Index, respectively. Non-adherence was modelled by uni- and multivariated analysis. Sixty-three percent of the patients were male, age 47.2 ± 12.9 years, and median post-transplant time 108.71 (49.0-266.0) months. We found 70.5% of patients were non-adherent through at least one method. Adherent patients presented higher self-efficacy scores (45.1 ± 4.9 vs 38.3 ± 8.6; P locus of control (OR 1.23, IC 1.04-1.45, P = 0.016) and lower intrinsic religiosity (OR 0.56, IC 0.38-0.84, P = 0.006). Our study showed that self-efficacy, chance locus of control, and intrinsic religiosity were associated with non-adherence to immunosuppressives. A broader perception of the kidney transplant patient´s integrality can help health professionals to design strategies to promote adherence in this population. © 2015 Asian Pacific Society of Nephrology.

    A woman's psychological health can affect prenatal behaviors. The purpose of this study was to examine the relationship between maternal beliefs, prenatal behaviors, and preterm birth (PTB) in a multiethnic population. This was a planned secondary analysis of a cross-sectional trial of postpartum women with singleton gestation. In all, 210 participants were given the Fetal Health Locus of Control (FHLC) scale to measure three primary maternal beliefs that influenced their prenatal behaviors (Internal Control, Chance, Powerful Others). Women who experienced preterm delivery and those who smoked during pregnancy scored the Chance category significantly higher than those who delivered term infants (p = .05; p = .004, respectively). This suggests those who smoked during pregnancy had a greater degree of belief that Chance influenced their infant's health status. Cultural differences also emerged specific to the impact of health care providers on PTB; with Hispanic women scoring Powerful Others the highest among the groups (p = .02). Nurses can plan a critical role in identifying at-risk women (smoking, strong Chance beliefs) while providing a clear message that taking action and modifying high-risk behaviors can reduce risk for adverse pregnancy outcome. © The Author(s) 2013.

    Locus of control (LOC) measures the extent to which individuals perceive control over their lives. Those with a more "internal" LOC feel self-sufficient and able to determine important aspects of their own future, while those with a more "external" LOC feel that their lives are governed by events beyond their control. Reduced internal LOC and increased external LOC have been found in cognitive disorders, but the neural substrates of these control perceptions are yet unknown. In the present study, we explored the relationship between amygdala functional connectivity and LOC in 18 amnestic mild cognitive impairment (MCI) and age-, sex-, and education-matched, 22 cognitively healthy controls (HC). Participants completed cognitive challenge tasks (Stroop Word Color task and Dual 1-back) for 20min, and underwent resting-state functional magnetic resonance imaging immediately before and after the tasks. We found significantly lower internal LOC and higher external LOC in the MCI group than the HC group. Compared to HC, MCI group showed significantly stronger positive associations between internal LOC and baseline right amygdala connections (including right middle frontal gyrus and anterior cingulate cortex), and stronger negative associations between internal LOC and change of these right amygdala connections. Across all participants, external LOC explained the relationships between associations of another set of right amygdala connections (including middle cingulate cortex and right superior frontal gyrus), both at baseline and for change, and performance in the cognitive challenge tasks. Our findings indicate that the right amygdala networks might be critical in understanding the neural mechanisms underlying LOC's role in cognitive aging. Copyright © 2017 Elsevier Ltd.

    Prenatal depression is a significant predictor of postpartum depression and is detrimental to fetal development. To examine whether depression during pregnancy is associated with social support and health locus of control (HLC). Data were collected from a sample of 208 Iranian pregnant women using a demographic questionnaire, the Edinburgh Postnatal Depression Scale, the multidimensional HLC Scale and the social support appraisals. Depression was experienced by 37% of participants. Overall, women reported higher level of family support (6.88 ± 1.15) than other supports (6.87 ± 1.29). Protective supports from other resources (6.87 ± 1.29) were higher than those from friends (5.94 ± 1.5). Internal, powerful others and chance beliefs had the highest mean scores. Social support and chance HLC significantly influenced the proposed mediator (depressive mood) in the linear regression model. Bivariate analysis showed significant associations between social support (friend, family and others) and depressive mood. Internal HLC had a significant association with social support and powerful others HLC. However, Pearson correlation coefficient was not significant between depressive mood and all dimensions of HLC. Clinicians could assess social support and chance HLC to identify and treat women at risk of prenatal depression. By providing support during pregnancy, depression levels in women and its effects on the fetus may be decreased, which could prevent postpartum depression. © The Author(s) 2015.

    2004-10-01

    The new psychological disorder of Internet addiction is fast accruing both popular and professional recognition. Past studies have indicated that some patterns of Internet use are associated with loneliness, shyness, anxiety, depression, and self-consciousness, but there appears to be little consensus about Internet addiction disorder. This exploratory study attempted to examine the potential influences of personality variables, such as shyness and locus of control, online experiences, and demographics on Internet addiction. Data were gathered from a convenient sample using a combination of online and offline methods. The respondents comprised 722 Internet users mostly from the Net-generation. Results indicated that the higher the tendency of one being addicted to the Internet, the shyer the person is, the less faith the person has, the firmer belief the person holds in the irresistible power of others, and the higher trust the person places on chance in determining his or her own course of life. People who are addicted to the Internet make intense and frequent use of it both in terms of days per week and in length of each session, especially for online communication via e-mail, ICQ, chat rooms, newsgroups, and online games. Furthermore, full-time students are more likely to be addicted to the Internet, as they are considered high-risk for problems because of free and unlimited access and flexible time schedules. Implications to help professionals and student affairs policy makers are addressed.

    2007-10-01

    To clarify effects of the Health Locus of Control (HLC) on smoking behavior, relationships between smoking and HLC among junior high school students were examined. The subjects of the initial study, conducted in 1991, were public elementary schoolchildren in their 3rd year (11-12 years old). We then investigated the same children again in 1994 and 1997. We here mainly used data for 265 students (136 males and 129 females) obtained in 1997 when they were public junior high school students in their 3rd year (14-15 years old). Questionnaires included items on smoking experience, smoking intention and the Parcel & Meyer's Children's HLC scales. 1. Smoking experience was not associated with the HLC. 2. Concerning smoking intention among boys, the neutral group expressed stronger beliefs in the powerful others HLC in 1994 and 1997 than the positive group. In addition, the positive group expressed weaker beliefs in the powerful others HLC in 1994 than the negative group. 3. Concerning smoking intention among girls, the neutral group expressed stronger belifs in the powerful others HLC in 1997 than the negative group. Smoking experience was not associated with the HLC. However, smoking intention was significantly associated with beliefs in the powerful others HLC. In this regard, the neutral group tended to have strong beliefs in the powerful others HLC suggesting that students in this group might be easily affected by other people in both positive and negative ways. In other words, they must be guided in a good fashion through appropriate health education.

  18. Locus of Control revisited: development of a new bi-dimensional measure

    Directory of Open Access Journals (Sweden)

    Javier Suárez-Álvarez

    Full Text Available Locus of control (LOC has a long tradition in Psychology, and various instruments have been designed for its measurement. However, the dimensionality of the construct is unclear, and still gives rise to considerable controversy. The aim of the present work is to present new evidence of validity in relation to the dimensionality of LOC. To this end, we developed a new measurement instrument with 23 items. The sample was made up of 697 Spanish participants, of whom 57.5% were women (M=22.43; SD= 9.19. The results support the bi-dimensionality of LOC: internal (α=.87 and external (α=.85. Furthermore, both subscales have shown adequate validity evidence in relation to self-efficacy, achievement motivation and optimism (r xy> .21. Statistically significant differences were found by sex (p < .05: men scored higher in external LOC and women in internal LOC. The validity evidence supports a two-dimensional structure for the LOC, and the measurement instrument developed showed adequate psychometric properties.

Logistic regressions analyzed associations between childhood and current economic stress, and lack of internal HLC. A 33.7% prevalence of men and 31.8% of women lack internal HLC, which was significantly associated with the covariates included. The accumulation hypothesis was partly supported because combined childhood and adulthood economic stress exposures were significantly associated with lack of internal HLC in a graded manner. The critical period hypothesis was not supported since the association between economic stress in childhood and lack of internal HLC was partly significant in the final model, and the association with adult (current) economic stress was also significant. The accumulation hypothesis was partly supported. The critical period hypothesis was not supported since both childhood and current economic stress experience were significantly associated with lack of internal HLC. Economic conditions in childhood as well as adulthood are plausibly of relevance for HLC.

    This paper describes the translation of the Multidimensional Health Locus of Control (MHLC) scales into American Sign Language (ASL). Translation is an essential first step toward validating the instrument for use in the Deaf community, a commonly overlooked minority community. This translated MHLC/ASL can be utilized by public health nurses researching the Deaf community to create and evaluate targeted health interventions. It can be used in clinical settings to guide the context of the provider-patient dialogue. The MHLC was translated using focus groups, following recommended procedures. Five bilingual participants translated the MHLC into ASL; five others back-translated the ASL version into English. Both focus groups identified and addressed language and cultural problems before the final ASL version of the MHLC was permanently captured on by motion picture photography for consistent administration. Nine of the 24 items were directly translatable into ASL. The remaining items required further discussion to achieve cultural equivalence with ASL expressions. The MHLC/ASL is now ready for validation within the Deaf community. PMID:18816365

    The human GH (hGH) gene cluster is regulated by a remote 5' locus control region (LCR). HSI, an LCR component located 14.5 kb 5' to the hGH-N promoter, constitutes the primary determinant of high-level hGH-N activation in pituitary somatotropes. HSI encompasses an array of three binding sites for the pituitary-specific POU homeodomain factor Pit-1. In the present report we demonstrate that all three Pit-1 sites in the HSI array contribute to LCR activity in vivo. Furthermore, these three sites as a unit are fully sufficient for position-independent and somatotrope-restricted hGH-N transgene activation. In contrast, the hGH-N transgene is not activated by Pit-1 sites native to either the hGH-N or rat (r)GH gene promoters. These findings suggest that the structures of the Pit-1 binding sites at HSI specify distinct chromatin-dependent activities essential for LCR-mediated activation of hGH in the developing pituitary.

    Health control beliefs were postulated to be associated with health behaviour. However, the results of studies assessing these associations suggest that they might not be universal. Among young adults associations have been reported, but the evidence is limited. The objective of this analysis was to re-examine these associations in a sample of university students in Germany. Data from a multicentre cross-sectional study among university students in North Rhine-Westphalia, Germany was used (N=3,306). The Multidimensional Health Locus of Control Scale with three dimensions (one internal and two external) and six aspects of health behaviour (smoking habits, alcohol use, drug consumption, being over-/ or underweight, physical activity, and importance of healthy nutrition) were evaluated. Students with stronger internal locus of control paid more attention to healthy nutrition and displayed a higher level of physical activity. Individuals with a stronger belief in health professionals were less likely to use drugs and paid more attention to healthy nutrition. Furthermore, higher scores in the second external locus of control dimension (beliefs in luck or chance) were associated with a higher likelihood of current smoking, lower physical activity and less attention to healthy nutrition. Students engaged more strongly in unhealthy behaviour if they believed that luck determines health. In contrast, believing in having control over one's own health was associated with more healthy behaviour. These findings support the need to consider health control beliefs while designing preventive strategies in this specific population.

    OBJECTIVES Locus of control (LOC) is a psychological construct reflecting the degree to which one perceives circumstances to be controlled by personal actions (internal LOC) versus outside factors (external LOC). Because LOC could influence a patient's medical decision-making and health behaviors, our objective is to describe the association between an increasing number of co-existing conditions and LOC in older adults. DESIGN Cross-sectional study using survey data from the North Carolina Established Population for Epidemiologic Studies of the Elderly (NC EPESE) dataset. SETTING and PARTICIPANTS Community-dwelling older adults aged 68 and older (N=3,212). MEASUREMENTS Nine common medical conditions were assessed by self-report. LOC was measured by standard questionnaire. Analyses adjusted for demographics, functional status (self-reported activities of daily living), cognition (Short Portable Mental Status Questionnaire), and depression score (Center for Epidemiologic Studies Depression Scale). RESULTS A higher number of chronic conditions was associated with external LOC (β=0.37, p<0.001). This relationship persisted after adjustment for age, race, sex, functional status, cognition, and depression (β=0.17, p <0.0001). Most individual conditions were not associated with LOC, although vision impairment (p<0.001) and arthritis (p<0.05) were associated with more internal LOC. CONCLUSION These results suggest that medically complex patients tend to exhibit a more external LOC, meaning that they perceive little personal control over circumstances and environment. Clinicians should be aware of this tendency, as external LOC may impede an older adult's willingness to engage in the considerable task of managing multiple chronic conditions. PMID:22458257

    To determine the preliminary psychometric properties of the Spanish form of the Multidimensional Health Locus of Control Scale (MHLC), which consists of three subscales: (1) Internalitu, (2) Powerful other externality, and (3) Chance externality. It also aims to study the relationship that the internal/external health control beliefs has with self-esteem, self-efficacy and perceived competence in a sample of nursing undergraduates. An observational and cross-sectional study including 109 nursing students who completed an anonymous questionnaire containing the demographic variables and the Spanish versions of the MHLC, the Rosenberg Self-Esteem Scale, the General Self-Efficacy Scale, and the Perceived personal competence Scale. A Cronbach's alpha coefficient of 0.713 for Internality, 0.665 for Chance and 0.728 for Powerful other were obtained. The test-retest correlation for the 18 items of the MHLC was 0.866. Internality subscale was positively and significantly correlated with self-efficacy and competence. By contrast, chance externality has negative and significant correlations with self-esteem and competence. There are no significant gender differences in any of the subscales. Younger subjects show greater tendency to external attribution. Factor analysis confirms the three-factor hypothesis. The results suggest that the Spanish form of the MHLC has adequate construct validity and acceptable metric properties. Also, they evidence the relationship between the attribution of health-related internal control with the perceived well-being and confidence in their own skills and abilities.

    Health locus of control refers to the belief that health is in one's control (internal control) or is not in one's control (external control). Among adults, external locus of control is associated with negative health outcomes, whereas internal locus of control is associated with favorable outcomes. Few studies examined these associations among youths. The objective of our study was to determine how locus of control relates to health care use, medication adherence, missed school, and readiness for transition to adult medical care for youths with chronic conditions. Participants at a camp for youths aged 6 to 17 years with chronic health conditions completed a survey measuring locus of control, readiness for transition to adult care, and medication adherence. Their parents completed a separate part of the survey about health care use and missed school days in the past year. A total of 163 youths completed the survey (78.5% white; 52.1% female; mean age, 12.3 y). Internal locus of control (β = 0.196; P = .013) and external Doctor locus of control with doctors controlling disease (β = 0.181; P = .025) were positively associated with transition readiness. External control by chance or with others controlling disease was negatively associated with transition readiness (β = -0.248; P = .002) and positively associated with emergency department visits (β = 0.225; P = .004) and with number of hospital inpatient nights at hospital (β = 0.166; P = .04). Adolescents with external control of their health by chance or by other people are at increased risk for negative health outcomes and may fail to develop the self-management skills needed for successful transitioning to adult care. Future studies should examine effects of changes in locus of control on health outcomes among youths.

    Locus of control is one of the most widely studied concepts in the history of personality psychology. In spite of its popularity and its associations with numerous relevant outcomes, the ability of locus of control to predict future behaviors involving parenting effectiveness has been under researched. The few parent locus of control children's outcome studies are characterized by cross-sectional methodologies that focus on mothers. The present study uses a prospective methodology to compare data on mothers' and fathers' locus of control with their child's behavior outcomes from a large scale research project, the Avon Longitudinal Study of Parents and Children (ALSPAC). Based on Rotter's Social Learning Theory published in 1954 and past empirical research, it was predicted and found that parent internality was associated with more positive child outcomes than parent externality. More specifically, when both parents were internal, their children had more positive outcomes in sleeping, eating, and tantrum behavior as compared to any other parent locus of control combination. However external parents had a less restrictive attitude which appeared to have a more beneficial effect on picky eating. Results confirmed how important parent locus of control is in the lives of children. Based on the findings, researchers are urged to develop interventions to change advice to parents and promote more internal locus of control among parents.

    Full Text Available Background and aimsThe degree to which a person perceives that the outcomes of the situations they experience are under their personal control is a psychological variable known asLocus of Control (LOC. Safety LOC is the construct that specifically address the internal andexternal LOC in industrial domain. Previous research suggest that safety locus of control can be assessed and used to predict safe behaviors.The main aim of this study was designing, validating, and determining the reliability of safety locus of control scale.MethodsFour hundred workers of Isfahan Steel Company participated in this study. The reliability coefficients were calculated in two different methods: test-retest and Cronbach alpha. In order to survey validity of the scale we used three methods including face validity, content validity and construct validity.ResultsWe established the content validity of the Persian translation by translating (and then back-translating each item from the English version into the Persian version. Exploratory principal components analysis yielded a three-factor structure that explaining a considerable proportion of the total variance (63.5. Moreover the fit indices of the Confirmatory FactorAnalysis turn out were sufficient to support three-factor structure. In addition, the reliability results were acceptable, too.ConclusionIn most studies, designing, validating and determining the reliability of scales are time consuming and costly and if there are valid and reliable scales in different topics, could avoid repetitious works in researches.The results showed that the reliability and validity of Safety Locus of Control was acceptable and respectable and is suggested as an applicable scale forindustrial psychology and safety studies in Iran.

    We investigated the direct and interaction influence of maternal age, breastfeeding self-efficacy (BSE), health locus of control (HLOC) on six dimensions of psychological wellbeing of breastfeeding mothers in Lagos, Nigeria. Data were collected from a convenience sample of 291 mothers attending health facilities in two suburb local government areas. The survey included socio-demographics (maternal age, marital status, ethnicity, education level and position of the baby currently breastfeeding), breastfeeding self-efficacy, health locus of control and psychological wellbeing scales. Independent variables were tested against sense of autonomy, positive relations with others, purpose in life, self-acceptance, environmental mastery and personal growth using factorial Multivariate Analysis of Variance. Results showed direct influence of BSE, HLOC and maternal age on various dimensions of psychological wellbeing. Interaction influences indicate BSE and HLOC on environmental mastery; BSE and maternal age on self-acceptance and HLOC and maternal age on sense of autonomy, positive relationship with others and self-acceptance respectively. In conclusion, maternal age, breastfeeding self-efficacy and health locus of control are vital for mothers to enjoy plenty dimensions of psychological wellbeing. Breastfeeding mothers need to be confident in their abilities to breastfeed and have control over their health-related behaviour in order to enjoy sufficient dimensions of psychological wellbeing.

    Many angiosperms, both monocotyledons and dicotyledons, heavily impregnate their vegetative and reproductive organs with solid particles of silicon dioxide (SiO2) known as opaline phytoliths. The underlying mechanisms accounting for the formation of phytoliths in plants are poorly understood, however. Using wild and domesticated species in the genus Cucurbita along with their F1 and F2 progeny, we have demonstrated that the production of large diagnostic phytoliths in fruit rinds exhibits a one-to-one correspondence to the lignification of these structures. We propose that phytolith formation in Cucurbita fruits is primarily determined by a dominant genetic locus, called hard rind (Hr), previously shown to code for lignin deposition. If true, this evidence represents a demonstration of genetic control over phytolith production in a dicotyledon and provides considerable support to hypotheses that silica phytoliths constitute another important system of mechanical defense in plants. Our research also identifies Hr as another single locus controlling more than one important phenotypic difference between wild and domesticated plants, and establishes rind tissue cell structure and hardness under the effects of Hr as an important determinant of phytolith morphology. When recovered from pre-Columbian archaeological sites, Cucurbita phytoliths represent genetically controlled fossil markers of exploitation and domestication in this important economic genus.

    Full Text Available Background: Work is an important source for establishing livelihoods and social occasions; however, it can also damage on person's health. The aim of the present study was to study of association between health locus of control and health promoting behaviors among employees of Bushehr University of Medical Sciences. Materials and Methods: This cross-sectional study was conducted on 208 employees of Bushehr University of Medical Sciences by using convenience sampling method. Data were collected by using standard questionnaires of health-promoting lifestyle and multidimensional health locus of control. Data analysis done by SPSS software version 20. Descriptive indicators and linear regression test was used. Results: Among regression models which related to health promoting behavior and its six dimensions, only there was a significant association between total behavior, physical activity and interpersonal relationship dimensions. Between demographic factors and health locus of control only internal health locus of control explained the health promoting behavior and it explained health promoting behavior changes  within 3.2% (R2=3.2%. None of the three health locus of control explained physical activity dimensions, while internal health locus of control explained interpersonal relation dimension positively and chance locus of control explained interpersonal relation dimension negatively and explained interpersonal relation changes within 4.9% (R2=4.9%. Conclusion: Due to the effect of internal health locus of control on health promotion behavior and interpersonal relationships, we should try to internalize locus of control by performing counseling programs to step toward improving employee health by improving behaviors related to health.

    2016-07-01

    Alcohol Myopia Theory (AMT; Steele & Josephs, 1990) purports that alcohol facilitates aggression by narrowing attentional focus onto salient and instigatory cues common to conflict situations. However, few tests of its counterintuitive prediction - that alcohol may decrease aggression when inhibitory cues are most salient - have been conducted. The present study examined whether an AMT-inspired self-awareness intervention manipulation would reduce heavy drinking men's intoxicated aggression toward women and also examined whether a relevant individual variable, locus of control, would moderate this effect. Participants were 102 intoxicated male heavy drinkers who completed a self-report measure of locus of control and completed the Taylor Aggression Paradigm (Taylor, 1967). In this task, participants administered electric shocks to, and received electric shocks from, a fictitious female opponent while exposed to an environment saturated with or devoid of self-awareness cues. Results indicated that the self-awareness manipulation was associated with less alcohol-related aggression toward the female confederate for men who reported an internal, but not an external, locus of control. Findings support AMT as a theoretical framework to inform preventative interventions for alcohol-related aggression and highlight the importance of individual differences in receptivity to such interventions.

    The first aim of the present study was to examine the factor structure of the traffic locus of control (T-LOC) scale in a Swedish sample of drivers. The second aim was to examine if this scale can be used to predict drivers' speeding behaviour. A sample of Swedish car owners (N=223) completed a questionnaire including questions based on the traffic locus of control (T-LOC) scale as well as questions about their speeding behaviour. The results showed a five factor solution including own skills, own behaviour, other drivers, vehicle/environment and fate. Own behaviour and vehicle/environment could be used to predict drivers' speeding behaviour on roads with a 90 km/h speed limit while none of the variables included in the traffic locus of control (T-LOC) scale could be used to predict drivers' speeding behaviour on roads with a 50 km/h speed limit. On 90 km/h roads own behaviour was positively related to drivers' speeding behaviour while vehicle/environment was negatively related to their speeding behaviour. Copyright 2010 Elsevier Ltd.

    Contemporary psycho-oncology focuses on the study of the psychological determinants of the functioning of cancer patients. Among the psychological factors that significantly affect the functioning of the patients are anxiety and depressive disorders. To assess the psychological functioning of patients with digestive system cancer in the cancer-treating process and to develop guidelines for psychological care dedicated to this group of patients based on the results of the study. A total of 69 patients aged 23 to 91 (average 56) years with digestive system cancer treated in the Gastroenterology Cancer Clinic in the Institute of Oncology in Warsaw were examined using HADS, Mini-MAC, and MHLC. The results were analysed using statistical tests and correlation analysis. Another 532 patients from other wards formed the reference group. Measured HLC, anxiety, and depression did not differ significantly from the overall patient population. The investigation of the relationships between anxiety and depression and mental adjustment to cancer showed a positive correlation between anxiety and depression and anxious preoccupation and hopelessness-helplessness, and negative correlation between anxiety and depression and fighting spirit. The obtained research results on the correlation of anxiety and depression with health locus of control show that the lower the severity of anxiety and depression, the higher the severity of internal health locus of control. The results confirm the necessity of psychological support forcancer patients showing evidence of destructive attitudes and external health locus of control, so that the severity of anxiety-depressive disorders can indirectly be reduced.

    The proliferation, differentiation, and survival of cells of the macrophage lineage depends upon signals from the macrophage colony-stimulating factor (CSF) receptor (CSF1R). CSF1R is expressed by embryonic macrophages and induced early in adult hematopoiesis, upon commitment of multipotent progenitors to the myeloid lineage. Transcriptional activation of CSF1R requires interaction between members of the E26 transformation-specific family of transcription factors (Ets) (notably PU.1), C/EBP, RUNX, AP-1/ATF, interferon regulatory factor (IRF), STAT, KLF, REL, FUS/TLS (fused in sarcoma/ranslocated in liposarcoma) families, and conserved regulatory elements within the mouse and human CSF1R locus. One element, the Fms-intronic regulatory element (FIRE), within intron 2, is conserved functionally across all the amniotes. Lineage commitment in multipotent progenitors also requires down-regulation of specific transcription factors such as MYB, FLI1, basic leucine zipper transcriptional factor ATF-like (BATF3), GATA-1, and PAX5 that contribute to differentiation of alternative lineages and repress CSF1R transcription. Many of these transcription factors regulate each other, interact at the protein level, and are themselves downstream targets of CSF1R signaling. Control of CSF1R transcription involves feed-forward and feedback signaling in which CSF1R is both a target and a participant; and dysregulation of CSF1R expression and/or function is associated with numerous pathological conditions. In this review, we describe the regulatory network behind CSF1R expression during differentiation and development of cells of the mononuclear phagocyte system. © 2017 The Author(s).

    Background : External locus of control orientation (ELOC) is a powerful predictor of adverse consequences in regard to health, educational attainment, inter-personal relationships and well-being. Although many cross-sectional studies have been carried out, relatively little is known about antecedent factors influencing the development of ELOC. Methods : Over 12,000 pregnant women who enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) in south-west England, had completed a brief version of the Adult Nowicki-Strickland Internal-External LOC scale, together with detailed questions concerning their own parents and childhood.  A series of hypothesis-free structured backwards stepwise logistic regression analyses used an exposome approach with ELOC as the outcome. Results : Significant positive associations were found with smoking of the parents of the surveyed women, including prenatal exposure, and their own onset of regular smoking in mid-childhood (6-11 years). Increased odds of ELOC were also found with the absence of their fathers in early childhood, presence of older siblings, and with being born and brought up in the same area as they resided in at the time surveyed. Protective influences in the surveyed women included positive rating of their mother's care, having a relatively educated mother, attending boarding school, their own age (the older they were, the less likely were they to have an external orientation), having a mentally ill parent, a sibling hospitalized or a relative die. Conclusions : There are two conclusions: (i) that not all stressful events contribute to the development of ELOC and it would be essential for models of antecedents of ELOC to take note of this complexity, and (ii) there are consistent (albeit unexpected) findings that highlight associations with cigarette smoke exposure of the woman from fetal life through to when starting to smoke regularly herself in mid-childhood. It is important that these findings

    Full Text Available Abstract Background Chronic inflammation and autoimmunity likely contribute to the pathogenesis of abdominal aortic aneurysms (AAAs. The aim of this study was to investigate the role of autoimmunity in the etiology of AAAs using a genetic association study approach with HLA polymorphisms. Methods HLA-DQA1, -DQB1, -DRB1 and -DRB3-5 alleles were determined in 387 AAA cases (180 Belgian and 207 Canadian and 426 controls (269 Belgian and 157 Canadian by a PCR and single-strand oligonucleotide probe hybridization assay. Results We observed a potential association with the HLA-DQA1 locus among Belgian males (empirical p = 0.027, asymptotic p = 0.071. Specifically, there was a significant difference in the HLA-DQA1*0102 allele frequencies between AAA cases (67/322 alleles, 20.8% and controls (44/356 alleles, 12.4% in Belgian males (empirical p = 0.019, asymptotic p = 0.003. In haplotype analyses, marginally significant association was found between AAA and haplotype HLA-DQA1-DRB1 (p = 0.049 with global score statistics and p = 0.002 with haplotype-specific score statistics. Conclusion This study showed potential evidence that the HLA-DQA1 locus harbors a genetic risk factor for AAAs suggesting that autoimmunity plays a role in the pathogenesis of AAAs.

    This study examined the moderating role of personality traits in the relationship between leader behavior and burnout. In two samples, employees (N = 91; N = 190) filled out the Maslach Burnout Inventory-General Survey and rated their leader's autocratic and charismatic leader behavior and their own neuroticism and internal work locus of control. As expected, neuroticism and internal work locus of control moderated the relationship between leader behavior and burnout. Charisma was associated with lower burnout, particularly for individuals low on internal locus. The relationship between autocratic leadership and burnout was positive for neurotic individuals, whereas for emotionally stable individuals this relationship weakened. These results were consistent across two independent samples: one with individual employee ratings of manager's leadership styles and the other with aggregate ratings of manager's leadership styles among employees in diverse organizations. Thus, although charismatic and autocratic leader behavior may respectively act to hinder or enhance overload and stress, the relationship between these leadership styles and burnout differs for followers with different traits.

    Diagnosis threat has been shown to produce detrimental effects on neuropsychological performance in individuals with mild traumatic brain injury (mTBI). Focusing on contact-sport players who are at great risk of mTBI, our study was designed to examine the moderating role of internal locus of control. Specifically, we predicted that following diagnosis threat (reminder of their risk of sustaining mTBI and of its consequences), low-internal contact-sport players would underperform (assimilation to the stereotype), while their high-internal counterparts would outperform (contrast effect). We predicted that effort and anxiety would mediate these effects. Contact-sport players and non-contact-sport players ("control" group) were randomly assigned to one condition (diagnosis threat or neutral) and then completed attention, executive, episodic memory, and working memory tasks. Regarding mediating and moderating variables, participants rated their effort and anxiety (self-report measures) and completed the Levenson (1974) locus of control scale. Regression-based path analyses were carried out to examine the direct and indirect effects. As expected, there was no effect of condition on the control group's performance. Contact-sport players with moderate and high levels of internal control outperformed (contrast effect) on executive and episodic memory tasks following diagnosis threat compared to the neutral condition. Additionally, the less anxiety moderate- and high-internal contact-sport participants felt, the better they performed on episodic memory and executive tasks. However, contact-sport players low in internal control did not underperform (assimilation effect) under diagnosis threat. Our results suggest that diagnosis threat instructions may have challenged moderate- and high-internal contact-sport participants, leading them to outperform compared to the neutral condition. Individuals who have moderate and high levels of internal locus of control may have higher

    The purpose of this study was to examine the prediction of depression on a group of Iranian older adults based on components of health locus of control. Sixty-six men and 42 women over the age of 55 were recruited from the retirement clubs in Shiraz, using convenience sampling. The participants completed the research questionnaires including the Geriatric Depression Scale (GDS) and the Multidimensional Health Locus of Control Scale (MHLC). The findings on health locus of control revealed that the highest score was on internal locus of control followed by God, powerful others and chance. The mean score on depression was on a normal range. Multiple regression analysis showed that two independent variables including internal control (ß = -.32, p control (ß = -.20, = p locus of control such as chance and powerful others as well as age did not predict depression. Findings also revealed that the independents variables explained 26% of the total variance of depression (R2 = .26, p locus of control on depression.

    Exposure is one of the most robust predictors of post-traumatic stress disorder (PTSD) symptoms in warfare situations. Yet, while many are sensitive to exposure, others do not develop PTSD. In the current study, we address how perceived media control along with external locus of control moderate effects of exposure on PTSD symptoms among 1268 individuals exposed to missile attacks (mean age=36.97). We expected that the coupling of low perceived media control, whereby one feels poor control over media consumption (an inability to stop), especially when irrelevant and non-informative (e.g., involuntarily viewing the same terror incident shown repeatedly in a looped fashion) along with a self-perception of external locus of control, will render participants highly vulnerable to exposure. As expected, results suggest that effects of exposure on PTSD are not automatic, rather, the coupling of both low media control along with believing that life event are controlled by external factors exacerbates effects of exposure. These findings bear practical implications, as both media control and locus of control can be modified by therapeutic interventions, rendering one less vulnerable to the detrimental effects of traumatic exposure.

    Obese individuals frequently experience weight-related bias or discrimination-even in healthcare settings. Although obesity bias has been associated with several demographic factors, little is known about the association of weight locus of control with bias against overweight persons or about weight bias among Chinese health professionals. The aim of the study was to examine attitudes toward obese patients in a sample of Chinese registered nurses (RNs) and the relationship between weight bias and nurses' weight locus of control. RNs working in nine community health service centers across Shanghai, China, answered three self-report questionnaires: The Attitudes Toward Obese Persons Scale (ATOP), the External Weight Locus of Control Subscale (eWLOC) from the Dieting Belief Scale, and a sociodemographic profile. Hierarchical, stepwise, multiple regression was used to predict ATOP scores. From among 385 invited, a total of 297 RNs took part in the study (77.1% response rate). Participants scored an average of 71.04 on the ATOP, indicating slightly positive attitudes toward obese persons, and 30.08 on the eWLOC, indicating a belief in the uncontrollability of body weight. Using hierarchical, stepwise, multiple regression, two predictors of ATOP scores were statistically significant (eWLOC scores and status as a specialist rather than generalist nurse), but explained variance was low. Chinese RNs seemed to have relatively neutral or even slightly positive attitudes toward obese persons. Those nurses who believed that obesity was beyond the individual's control or worked in specialties were more likely to have positive attitudes toward obese people. Improved understanding of the comprehensive etiology of obesity is needed.

    Full Text Available The Multidimensional Locus of Control IPC Scale (IPC LOC Scale is an instrument for assessing the locus of control on adults. The aim of the present study is to translate the IPC LOC Scale and evaluate its reliability and validity in a sample of Greek teachers. Data were collected from a nationwide sample of 3668 educators of all levels and specialties. The Cronbach’s alpha coefficient was used to determine the internal consistency reliability. A confirmatory factor analysis (CFA was conducted in order to test the construct validity of the questionnaire. Validity was further examined by investigating the correlation of the IPC LOC Scale with the Rosenberg self-esteem scale (RSES and its association with several demographic and work-related data. Internal consistency reliability was satisfactory with a Cronbach’s alpha above 0.70 for all LOC dimensions. CFA confirmed that the items composing the three subscales of the IPC LOC Scale measure the same construct. Also, the root mean square error of approximation (RMSEA, the comparative fit index (CFI and the goodness of fit index (GFI values were 0.053, 0.951, and 0.937, respectively for the three-factor model, further confirming the manufacturer’s theory for the three latent variables, Internality, Powerful Others, and Chance. Intercorrelations and correlation coefficients between the IPC LOC Scale and the RSES were significant, while age and sex differences were also found. The Greek version of the IPC LOC Scale was found to have satisfactory psychometric properties and could be used to evaluate the locus of control in Greek teachers.

    In China, the number of college students using mobile phone based messaging and social networking applications like WeChat is increasing rapidly. However, there has been minimal research into the addictive nature of these applications and the psychological characteristics associate with their excessive use. There is also no published scale available for assessing excessive use of WeChat and similar applications. In the current study, we collected data from 1,245 college students in China (715 females) and developed the WeChat Excessive Use Scale (WEUS). We then assessed the relationship between excessive use of WeChat and excessive use of a social networking application-Weibo, problematic use of mobile phones, external locus of control, and social interaction skills. Our 10-item scale featured three factors, namely- “mood modification,” “salience” and ‘‘conflict”- critical factors in assessing different forms of addiction. The WEUS was found to be a reliable instrument in assessing excessive use of WeChat as it showed good internal consistency and correlated with other measures of problematic use social networking and mobile phone addiction. Our results showed that excessive users of WeChat are more likely to excessively use Weibo than they are to problematically use mobile phones. Our study also showed that greater excessive use of WeChat is associated with higher external locus of control and greater online social interaction skills. These results reveal that WeChat has unique and strong appeal among college students in China. Further, practitioners should consider dealing with malleable factors like locus of control and real life social skills in treating people with problematic messaging and social networking.

    Full Text Available BACKGROUND: Pain is a multidimensional experience. Locus of control is an important factor related to chronic pain experience and treatment. There is a gap in the literature when discussing issues related to pain evaluation in elderly. OBJECTIVES: To analyze the factorial structure, intra and inter-rater reliability of the Brazilian version of the Pain Locus of Control Scale - Form C for elderly with chronic pain living in the community. METHODS: One hundred and eighty one elderly individuals (71.5±6.8 years of age answered a clinic and social-demographic questionnaire and the PLOC-C scale. A factorial analysis with varimax rotation of the PLOC-C scale was performed. The scalewas applied twice by two observers to evaluate the intra and inter-rater reliability analyzed using Pearson's Correlation Coefficients. RESULTS: The factorial analysis of the 18 item PLOC-C scale revealed six factors. Four items (1 and 6 from the chance locus of control subscale; 2 and 4 from the internal locus of control subscale migrated toward unpredictable factors in the original factorial structure. Analysis with the removal of the four items demonstrated a better factorial structure and higher levels of internal consistency (α=0.836 and 0.669 and reliability (intra-examiner: r=0.65 and 0.93; inter-examiner: r=0.82 and 0.92 when compared to the complete subscales. The variance explained was of 48.7% for the 18 items and 62.4% for the 14 items scale. CONCLUSION: The results demonstrate a better applicability of the reduced scale on the sample. The reduced version may contribute to greater knowledge and consequently better chronic pain management in the elderly.CONTEXTUALIZAÇÃO: Dor é uma experiência multidimensional.

    Full Text Available Objective: To analyze the relationship between sexual and contraceptive attitudes, the locus of health control and self-esteem among students of a private institution of higher education. Methods: Descriptive and correlational study with a quantitative approach, performed in a higher education school in Lisbon, with 152 students, from the 1st to the 4th year of undergraduate courses in Nursing, Physiotherapy, Cardiopneumology and Radiology. As research instrument, it was used a questionnaire with rating scales on ‘sexual attitudes’, ‘contraception attitudes’, ‘locus of health control’ and ‘self-esteem’. The data obtained was analyzed using descriptive and inferential statistics. Results: The majority of students (90.7% have already had sexual intercourse. Sexual attitudes were influenced by gender (p=0.0035, but not by the start of sexual activity or by the course’s year (p>0.05. Contraceptive attitudes were related to the year that students attended (p=0.031 and to gender (p=0.029. The external locus of control, on average, was higher among girls (29.2 than boys (30.1. The self-esteem increased with the student’s age (p=0.003. Conclusion: Investment in the area of sexual education is needed in the undergraduate programs, since the young people live their days in the school setting, spending little time with their families. The university should assume a special position in the development of the concept of sexuality based on the holistic perspective of the human being, promoting sexual education as essential in the construction of human identity and fundamental for health promotion doi: http://dx.doi.org/10.5020/18061230.2013.p505

    In the field of health psychology, the control has consistently been considered as a protective factor. This protective role has been also highlighted in eating attitudes' domain. However, current studies use the one-dimensional scale of Rotter or the multidimensional health locus of control scale, and no specific eating attitudes' scale in the sport context exists. Moreover, the social influence in previous scales is limited. According to recent works, the purpose of this study was to test the internal and external validity of a multidimensional locus of control scale of eating attitudes for athletes. One hundred and seventy-nine participants were solicited. A confirmatory factorial analysis was conducted in order to test the internal validity of the scale. The scale external validity was tested in relation to eating attitudes. The internal validity of the scale was verified as well as the external validity, which confirmed the importance of taking into consideration social influences. Indeed, the 2 subscales "Trainers, friends" and "Parents, family" are related respectively positively and negatively in eating disorders. Copyright © 2016 L'Encéphale, Paris.

    Social and political instability have become common situations in many parts of the world. Exposure to different types of traumatic circumstances may differentially affect psychological status. The aim of this study was to compare the relationship between personal perceptions of control over the events happening in one's life and psychological distress in two groups who experienced physical trauma but differed as to whether the trauma was a result of political upheaval and violence. Views on the extent to which the state was interested in the individual were also assessed. The sample consisted of 120 patients who were injured in the Cairo epicenter and 120 matched controls from the greater Cairo area whose injuries were from other causes. The Brown Locus of Control Scale and the Symptom Checklist-90-Revised (SCL 90-R) were administered approximately three months after the January 2011 start of the demonstrations and subsequent overthrow of the government. The groups did not differ on locus of control. For both groups, externality was associated with greater distress, suggesting a relationship between perceived helplessness in controlling one's life and distress. The Cairo group scored significantly higher than the control group on the SCL 90-R Global Severity Index (GSI) and Positive Symptom Total (PST). Perceptions of state interest in the population were low; overall, 78% viewed the state as having little or no interest in them. Discussion The relationship between exposure intensity and psychological distress is examined. In addition, differences in findings in populations experiencing political chaos compared with other types of disasters are considered. Beliefs regarding personal control over one's life circumstances are more closely associated with psychological distress than the circumstances in which the trauma occurred.

    Chronic pain is significantly influenced by behavioral, cognitive, and emotional factors. Few studies have investigated the health locus of control (HLC)-one's belief regarding where control over one's health lies-as it relates to patients with chronic pain. The purpose of this prospective, cross-sectional study was to examine the relationship between depression and health/pain locus of control (HLC) in adult patients with persistent pain. A series of questionnaires was administered to chronic pain patients, and these questionnaires were scored and analyzed. Patients were categorized into 3 groups based on health locus of control (internal, chance, powerful-others), which were examined with respect to their depression scores using analysis of variance. A total of 131 patients completed the study: 33% belonged to the internal group, 39% in the chance group, and 28% in the powerful-others group. The 3 groups had depression scores of 40 (SD = 8), 47 (SD = 10), and 42 (SD = 8), respectively. We found significant difference in depressions scores between the chance group and the internal group (P locus of control are less depressed compared to patients with fatalistic views on their health/pain in the chance group. The chance dimension of the Multidimensional Health Locus of Control scale was found to be a potential predictor of psychiatric comorbidities such as depression in the chronic pain patient population. © 2016 World Institute of Pain.

    Full Text Available The current study investigated a longitudinal data set of 4790 adults examining a set of socio-demographic and psychological factors that influence adult financial well-being. Parental social status (at birth, childhood intelligence and self-esteem (at age 10, locus of control (at age 16, psychological distress (age 30, educational qualifications (age 34, current occupation, weekly net income, house ownership status, and number of rooms (all measured at age 38 years were examined. Structural Equation Modelling showed that childhood intelligence, locus of control, education and occupation were all independent predictors of adult financial well-being for both men and women. Parental social status and psychological distress were also significant predictors of the outcome variable for men, but not for women. Whereas for women, in comparison to men, the effects of current occupation and childhood intelligence on the outcome variable appeared to be stronger. The strongest predictor of adult financial well-being was current occupational prestige, followed by educational achievement. The gender deferential of financial well-being indicators and its implications are discussed.

    Expression of mammalian GH is normally restricted to somatotropes and somatolactotropes (somatotrope lineages) in the anterior pituitary. The basis for this restriction remains incompletely understood. Recent studies indicate that deoxyribonuclease I hypersensitive site I (HSI) of the hGH locus control region, located at -14.5 kb relative to the hGH-N promoter, acts as a potent long-range enhancer of hGH-N transcription. Here we report that HSI is also critical to somatotrope-restriction of hGH-N expression. Loss of HSI activity, either by direct inactivation of HSI or by interference with HSI-dependent downstream events, results in a relaxation of hGH-N cell-type specification with expansion of hGH-N expression to the full spectrum of Pit-1 positive pituitary cell types. These findings expand the defined roles for HSI of the hGH locus control region to include somatotrope lineage restriction as well as transcriptional enhancement of hGH-N gene expression.

    Health-promoting behavior plays an important role in reducing the burden of coronary heart disease. Self-esteem and health locus of control may contribute to health-promoting behavior, and coping styles may mediate these associations. The aims of our study were to examine whether self-esteem and health locus of control are associated with health-promoting behavior and examine the possible mediating effect of coping styles in patients with coronary heart disease. Health-promoting behavior, self-esteem, health locus of control, and coping styles were assessed in 272 hospitalized patients (60 ± 12 years, 61% male) with coronary heart disease. Hierarchical regression analysis was conducted to analyze the relationships between health-promoting behavior and other variables. Mediation effect was examined according to the methods of Baron and Kenny. The mean score for health-promoting behavior was 2.57 ± 0.51; 38.2% of patients (n = 104) scored lower than 2.5. Self-esteem (β = .139, P locus of control and health-promoting behavior. Confrontation plays a mediating role in the association among self-esteem, internal health locus of control, and health-promoting behavior. Strategies should be undertaken to encourage the use of confrontation coping style, which will facilitate health-promoting behavior.

    In health psychology, several models are being constructed to understand human behaviour. Multidimensional health locus of control (MHLC) is one among them. We sought to know the relationship of MHLC with dental plaque and gingival status before and after oral health education programme among 286 college students, aged 18-21 years in Davangere city. Multidimensional health locus of control questionnaire consisting of questions measuring internal health locus of control (IHLC), powerful others health locus of control (PHLC) and chance health locus of control (CHLC) was administered to students. Dental plaque and gingival health status were recorded using Plaque Index (PLI) and Gingival Index (GI), 1967. Oral health education was provided using power point presentation after the baseline oral examination. After 10 weeks of intervention, the students were given the same proforma followed by the assessment of plaque and gingival status. A negative correlation was observed between PHLC and IHLC with PLI and GI and positive correlation of CHLC with PLI and GI at a level of P education was found to be effective and this could change the behaviour of individuals. © 2014 John Wiley & Sons A/S.

    Full Text Available Cada vez más organizaciones involucran a su personal en los procesos presupuestarios bajo la premisa de que una mayor participación mejorará la consecución de las metas presupuestarias. Sin embargo, la participación no siempre conduce a mejoras en el rendimiento, ya que las características de personalidad hacen que los individuos reaccionen de forma diferente ante situaciones presupuestarias similares. En este trabajo se estudia el papel de la característica de personalidad locus de control en la relación participación presupuestaria-rendimiento mediante un experimento de laboratorio con 115 estudiantes de grado. Los resultados confirman que el locus de control influye en los efectos de la participación presupuestaria sobre la eficiencia de los individuos. Nuestros resultados revelan, también, que individuos con locus de control externo alcanzan menores rendimientos que los sujetos con locus de control interno en entornos participativos, pero no obtienen rendimientos diferentes en función del entorno. Además, nuestros resultados muestran que solo para niveles bajos del locus de control (internos una mayor participación se traduce en mayores rendimientos.

    Thus, the present research was carried out aimed at determining the relationship between self-esteem and locus of control and quality of life during treatment stages in the patients referring to drug addiction rehabilitation centers of Borujen city, Iran. The current study was a sectional research of descriptive correlation type. The research sample was 150 individuals of patients referring to addiction rehabilitation centers of Borujen city. For data gathering, Rosenberg Self-esteem Scale, Rotter's Locus of Control Scale, and SF36 Quality of Life Questionnaire were used. Following collection of questionnaires, the data were analyzed using SPSS/16 software. According to the results, in the 12 th day of treatment, 96 patients exhibited moderate self-esteem, 102 patients had internal locus of control, and the score of their overall quality of life was 40.43±12.71. Furthermore, Pearson's correlation coefficient indicated that a significant and positive relationship was observed between locus of control and quality of life during different treatment stages. It seems that quality of life improves during addiction treatment stages due to improvement of personality traits including locus of control and self-esteem. Therefore, consultation methods as a very crucial priority in addiction rehabilitation centers shall be taken into account by the health sector authorities and managers and can play an essential role in enhancing quality of life.

  11. Filling in the Gap of Human Chromosome 4: Single Molecule Real Time Sequencing of Macrosatellite Repeats in the Facioscapulohumeral Muscular Dystrophy Locus.

    Full Text Available A majority of facioscapulohumeral muscular dystrophy (FSHD is caused by contraction of macrosatellite repeats called D4Z4 that are located in the subtelomeric region of human chromosome 4q35. Sequencing the FSHD locus has been technically challenging due to its long size and nearly identical nature of repeat elements. Here we report sequencing and partial assembly of a BAC clone carrying an entire FSHD locus by a single molecule real time (SMRT sequencing technology which could produce long reads up to about 18 kb containing D4Z4 repeats. De novo assembly by Hierarchical Genome Assembly Process 1 (HGAP.1 yielded a contig of 41 kb containing all but a part of the most distal D4Z4 element. The validity of the sequence model was confirmed by an independent approach employing anchored multiple sequence alignment by Kalign using reads containing unique flanking sequences. Our data will provide a basis for further optimization of sequencing and assembly conditions of D4Z4.

We combine guanxi in Chinese societies, power, influence tactics, and locus of control in the research model, 147 family business in Taiwan are proceeded the questionnaire survey, and 332 valid copies are retrieved. With hierarchical regression analysis, the findings show the close relations between managers’ power, perceived guanxi and leadership behavior, in which managers’ locus of control play a critical role. It is therefore suggested that the assignation of managers in such type of enterprises should be more cautious; in addition to the communication with the subordinates, the fitness with personality and competence should be concerned in order to maintain the favorable work efficiency and the relations between superiors and subordinates.La histórica y especial red de relaciones de la sociedad china se basa en lazos de sangre o en conexiones familiares emocionales de las que los negocios familiares son la mejor representación.

    Full Text Available Background: The influence of various psychological factors and coping mechanisms on quality of life (QOL in cancer patients has been well established. We evaluated locus of control and attributional styles, and their association with coping styles and quality of life (QOL among Iranian cancer patients. Methods: This cross-sectional study was conducted on patients with breast cancer and patients with colorectal cancer in stage I to III. Patients were assessed for demographic and disease characteristics, cancer-related symptoms, locus of control, attributional styles, coping styles, and QOL. Results: From 140 invited patients, 100 patients participated in the study. Data of 55 patients with breast cancer and 22 patients with colorectal cancer were appropriate and included for analysis (mean age of 47.5 ± 7.9 years, 89.6% female. Factors positively associated with QOL included educational level, internal locus of control, overall hopefulness, and confrontive, optimistic, and self-reliant coping styles (r = 0.228 to 0.426. Factors negatively associated with QOL included age, symptoms severity, overall hopelessness, and fatalistic and emotive coping styles (r = -0.221 to -0.674. Internal locus of control and hopefulness were associated with confrontive/adaptive coping styles (r = 0.226 to 0.381, while external locus of control and hopelessness were associated with evasive/maladaptive coping styles (r = 0.208 to 0.381. Conclusion: These results indicate that internal locus of control, hopefulness, and positive attributional styles are associated with more adaptive/confrontive coping strategies and better QOL in Iranian cancer patients. Further studies with more comprehensive psychosocial evaluation in a larger sample of cancer patients are warranted.

    BACKGROUND This study aimed to determine the relationship of health behaviors with the health locus of control and the sense of self-efficacy against the background of socio-economic factors and self-rated health among students of the Universities of the Third Age (U3As). MATERIAL AND METHODS The study included 320 U3A students, with mean age of 67.5 years. The following research tools were used: Health Behavior Inventory (HBI), Multidimensional Health Locus of Control Scale (MHLC), Generalized Self-Efficacy Scale (GSES), and an original survey of the author's own design. RESULTS Mean total HBI and GSES scores were 90.63 and 30.12, respectively. These results are satisfactory. A slight predominance of internal health locus of control was documented. A number of significant correlations were found between the HBI, GSES, and MHLC scores, except for the MHLC subscale expressing the influence of chance. Educational attainment was shown to have a significant impact on the scores for the positive attitude and proper dietary habits subscales of HBI, as well as on the GSES scores. Economic status of the participants influenced the levels of positive attitude, internal health locus of control, and self-efficacy. Furthermore, internal health locus of control was found to be modulated by subjective health of the respondents. The scores for external health locus of control and the influence of chance increased significantly with age. CONCLUSIONS The currently noticeable emphasis placed on lifelong education should serve as a good prognostic factor for health behaviors and personal health resources for years to come.

    God Locus of Health Control (GHLC) scale is an instrument for assessing to what extent one believes that God controls his/her health or disease. The aim of this study was to describe the cultural adaptation of this scale and to investigate the psychometric properties of Persian version. At first, the scale was forward-translated to Persian, and then, backward-translation was conducted. Finally, the synthesized back-translated version was prepared and compared to the draft Persian-language version of the GLHC. In the next step, in order to test cognitive debriefing, the Persian-language version of the questionnaire was completed by 20 pilgrims. Final version of Persian GHLC scale was answered by 600 pilgrims attending religious holy places. Mean age of respondents was 33.15 (±11.04) years. There was a positive correlation between six items of GLHC scale and inter-item correlation coefficients. The Cronbach's alpha coefficient was 0.84. Exploratory factor analysis showed that the G LHC scale had a one-factor structure. The factor loadings for all items ranged from 0.57 to 0.77. Residual correlations of all items were between -0.2 and +0.2. The people with lower income had significantly higher score of GLHC scale. GLHC scale score had a significant positive correlation with DUREL subscale and MHLC Chance Externality subscale score. There was no a significant correlation between GLHC scale score and Multidimensional Health Locus of Control (MHLC) Internality and Powerful subscales scores. The results of the present study showed that the Persian version of GHLC scale has acceptable factorial validity and internal consistency reliability.

    Full Text Available Background Parenting style impacts children’s psychosocial development. Students with borderline intellectual functioning (BIF are especially sensitive to the quality of parental care. The objective of this study was to compare parenting styles of mothers of children with BIF and mothers of typically developing peers, and establish associations between parenting styles and children’s psychosocial traits, which determine their school functioning. Participants and procedure Forty-two primary school students in Grades 4 to 6, their teachers, and mothers participated in the study. Based on their IQ level they comprised two groups: students with BIF (criterion group; n = 21 and students with average IQ (comparison group; n = 21. A series of measures were used to assess mothers’ parenting style and students’ psychosocial traits. Questionnaires measuring students’ psychosocial pro­perties were administered to children and their teachers in order to compare their perspectives. Results Mothers of children with BIF in comparison to mothers in the control group presented greater inclinations towards over-parenting. Based on self-reports, students with BIF did not differ from their typically developing classmates in terms of school motivation, anxiety, locus of control, or social adjustment, despite their lower academic performance. According to teachers, students with BIF had significantly lower school motivation and delayed socialization. For students with BIF but not for the comparison group, a negative correlation was found between mothers’ tendency to dominate over their child and students’ locus of control and school motivation. Conclusions Children with BIF are especially sensitive to the quality of mothers’ parenting style, which can have an adverse effect on their school adjustment.

    To examine the role of internal and external locus of control (LOC) in the frequency of physician visits longitudinally. A nationally representative, longitudinal cohort study of German households. Data were used from the years 2005 and 2010. Data were gathered from the German Socio-Economic Panel (GSOEP). The ten internal and external LOC items in the SOEP are based on a scale by Krampen. The number of physician visits in the last 3 months was used as outcome variable. According to Andersen's behavioural model, predisposing characteristics, enabling resources, and need factors were included as control variables. Fixed-effects Poisson regressions showed that physician visits increased with increasing external LOC, whereas changes in internal LOC were not associated with changes in physician visits. Furthermore, physician visits increased with need factors (decreased self-rated health; onset of disability), whereas predisposing characteristics and the enabling resources were not associated with physician visits. Our findings emphasize the meaning of changes in external LOC for physician visits. As there is evidence that interventions can change the LOC, efforts to modify external LOC might be beneficial for the health care system. Statement of contribution What is already known on this subject? A few cross-sectional studies have investigated the association between locus of control (LOC) and health care use. Longitudinal studies are needed to get a deeper understanding of the causal relationship between these factors. What does this study add? Our longitudinal study provides insights into the impact of general internal and external LOC on physician visits. This is the first study examining the long-term relation in Germany using a population-based sample. © 2017 The British Psychological Society.

En general, los pacientes con esquizofrenia demuestran un locus de control externo más en comparación con las poblaciones no psiquiátricas. Antes de investigación en la esquizofrenia también sugiere que la relación entre mayores síntomas psicóticos y la disminución del bienestar psicológico es más fuerte para los individuos que apoyan un locus de control externo más. Esta relación no ha sido probado en una población no clínica. En una muestra de la diversidad étnica de 420 participantes, este estudio encontró, en línea con las hipótesis, de que un locus de control externo más se asoció negativamente con el bienestar psicológico. Mientras que los síntomas psicóticos subclínicos se asociaron negativamente con el bienestar psicológico, el locus de control no moderó la relación general entre la psicosis subclínica y el bienestar psicológico como se esperaba. Los análisis secundarios examinaron las relaciones entre los síntomas psicóticos subclínicos, locus de control y el bienestar psicológico por el origen étnico y sugirieron que la etnicidad moderó la relación entre un locus de control externo y la disminución de bienestar. En otras palabras, para las minorías que había una relación entre una mayor locus de control externo y la disminución de bienestar, pero no para los blancos.

    The locus of health control is one of the individual characteristics determining the diet of an individual. The aim of this study was to analyse the consumption frequency of selected food products depending on the locus of health control in a group of pregnant women residing in a small town and rural setting in Małopolska district. The study was conducted in a group of 300 pregnant women from Małopolska region, who were between 20 and 40 years of age (29.02 +/- 6.33). The consumption frequency of food products was examined with a prepared questionnaire, in a 7-item scale (from 7 points--several times a day to 1 point--never). The locus of health control was determined with the MHLC scale developed by K.A. Wallston et al., and adapted by Z. Juczyński. The relationship between the MHLC scale and the frequency of consumption of various products was estimated on the basis of Spearman's coefficients of rank correlation and the Mann-Whitney U test, using Statistica 10.0 software. Higher level of internal control (MHLC-I) was associated with significant increase in the consumption frequency of orange and red vegetables (p locus of health control (MHLC-C) was associated with significantly reduced frequency of consuming whole grains (p control made more rational nutritional choices significantly more frequently than those with the external control.

    The purpose of this study was to examine the relationship between hematopoietic cell transplant candidate and proxy advance care planning (ACP) behavior and attitudes. A total of 49 candidates and 44 proxies completed the Advance Directive Attitudes Survey, Multidimensional Health Locus of Control Scale, Family Decision Making Self-Efficacy Scale, and the State-Trait Anxiety Inventory. In all, 45% of candidates reported completing an advance directive (AD), while only 26% had ADs on file; 80% of candidates discussed ACP wishes with their loved ones and 15% discussed ACP wishes with their medical team. The AD completers were significantly (1) older, (2) more positive about ADs, and (3) were less likely to believe that health events happen by chance. Discrepancies between reported ACP behavior and communication with health care practitioners have implications for end-of-life care. © The Author(s) 2013.

    The present study advances the understanding of how medical drama viewing influences healthy lifestyle behaviors (e.g., smoking, exercising, and consuming vegetables) by examining the role of the health locus of control (HLOC) beliefs and education level. An analysis of nationally representative data reveals that watching medical dramas is positively associated with chance and powerful others' HLOC beliefs. In addition, healthy lifestyle behaviors are positively associated with the internal HLOC belief and are negatively associated with the chance and powerful others' HLOC beliefs. Research findings demonstrate that there are indirect effects of medical drama viewing on these behaviors via chance and powerful others' HLOC beliefs. The indirect effect through the powerful others' HLOC belief is also contingent on the education level. The implications for the role of HLOC beliefs and education level in terms of the effects of medical dramas on health-promoting behaviors are discussed.

    Reporter gene assays are widely used in high-throughput screening (HTS) to identify compounds that modulate gene expression. Traditionally a reporter gene assay is built by cloning an endogenous promoter sequence or synthetic response elements in the regulatory region of a reporter gene to monitor transcriptional activity of a specific biological process (exogenous reporter assay). In contrast, an endogenous locus reporter has a reporter gene inserted in the endogenous gene locus that allows the reporter gene to be expressed under the control of the same regulatory elements as the endogenous gene, thus more accurately reflecting the changes seen in the regulation of the actual gene. In this chapter, we introduce some of the considerations behind building a reporter gene assay for high-throughput compound screening and describe the methods we have utilized to establish 1536-well format endogenous locus reporter and exogenous reporter assays for the screening of compounds that modulate Myc pathway activity.

    Full Text Available This research adopts the theory of planned behavior. The purpose of this research is to examine the effects of attitude toward behavior, subjective norms, and perceived behavioral control on the manager’s intention to commit fraudulent financial reporting moderated by locus of control. This research applies a mail survey as data collection method and judgment sampling as sample collection method. Research subjects are accounting and finance managers of manufacture industry in Indonesia. There are 1,700 questioners to be distributed during the research. However, there are only 148 of the 186 returned questioners to be included in the research analysis. Empirical evidence finds that locus of control moderates the effect of attitude toward behavior and subjective norms on the manager’s intentions to commit fraudulent financial reporting. However, locus of control does not moderate the effect of perceived behavioral control on the manager’s intentions to commit fraudulent financial reporting. These results indicate that the presence of locus of control - which is the belief in one's self - strengthen the influence of attitudes and subjective norms to make a fraudulent financial statements into action.

    A high percentage of cancer patients use complementary and alternative medicine (CAM). The aim of our study was to learn more about the association of CAM usage, information needs, perceived impact of disease, locus of control and self-efficacy of cancer patients. We asked patients attending a series of lectures on CAM using a standardized questionnaire which integrated questions on information needs, CAM and validated short questionnaires on self-efficacy, perception of the disease and locus of control of reinforcement. One hundred and eighty-five patients answered the questionnaire, from whom 45 % used CAM. Sixty percentage disclosed using CAM to the general practitioner and 57 % to the oncologist. Physicians and nurses, print media and the Internet are the most important source of information on CAM (used by 20-25 % each). Impact on neither daily life, perceived personal control nor coherence was associated with CAM usage, disclosure to physicians or sources of information. There also was no association between CAM usage and self-efficacy. In contrast, there was a significant association between CAM user rate and a high external locus of control. While CAM usage is agreed upon by many physicians due to the idea that it helps patients to become active and feel more in control of the disease, our data are in favor of the contrary. A strong perception of external locus of control seems to be a driver of CAM usage. Physicians should be aware of this association when counseling on CAM.

    Health Locus of Control (HLC) classifies our beliefs about the connection between our actions and health outcomes (Skinner, 1996) into three categories: "internal control", corresponding to health being the result of an individual's effort and habits; "control by powerful others", whereby health depends on others, such as doctors; and "chance control", according to which health depends on fate and chance. Using Choice Experiments we investigate the relationship between HLC and willingness to change lifestyle, in terms of eating habits, physical activity and associated cardiovascular disease risk, in a 384 person sample representative of the 40-65 aged population of Northern Ireland administered between February and July 2011. Using latent class analysis we identify three discrete classes of people based on their HLC: the first class is sceptical about their capacity to control their health and certain unhealthy habits. Despite being unsatisfied with their situation, they are reluctant to accept behaviour changes. The second is a group of individuals unhappy with their current situation but willing to change through exercise and diet. Finally, a group of healthy optimists is identified, who are satisfied with their current situation but happy to take more physical activity and improve their diet. Our findings show that any policy designed to modify people's health related behaviour should consider the needs of this sceptical class which represents a considerable proportion of the population in the region.

    2018-01-01

    The present study sought to examine the interactive effects of an external locus of control and interaction in a negative peer group climate on men’s perpetration of physical aggression and infliction of injury toward their female intimate partners. Participants were 206 heterosexual males recruited from the metro-Atlanta community who completed self-report measures of external locus of control, involvement in a negative peer group climate, and physical aggression and infliction of injury against intimate partners during the past 12 months. Negative peer group climate was conceptualized as a peer group that displays behavior which may instigate aggressive norms, attitudes, and behaviors. Results indicated that men with an external locus of control were more likely to perpetrate physical aggression toward and inflict injury on their intimate partners if they reported high, but not low, involvement in a negative peer group climate. These results extend current research suggesting external locus of control as a risk factor for intimate partner aggression by highlighting the impact of negative peer groups. Implications and future intervention research are discussed. PMID:25389191

    Full Text Available This study examines personal factors and work locus of control as determinants of job performance of library personnel in federal colleges of education in Nigeria. A survey research design of a correlational type was adopted. The total enumeration method was used to cover all the 195 library personnel. A questionnaire with the Work Locus of Control Scale (WLCS was used as an instrument to collect data. Two research questions and two hypotheses, tested at the 0.05 level of significance, were postulated for the study. Multiple regression and correlational analyses were used in analyzing the data collected. The study reveals that there was a significant relationship among independent variables (age, years of working in the library, academic qualification, position/rank, monthly salary, and work locus of control and job performance of respondents. The study also shows that the joint effects of independent variables on job performance of library personnel were significant (F(7;165 = 3.95; P < .05. It is recommended that library managers and administrators should endeavor to recruit people with internal locus of control, give considerations to age, academic qualification, job position/rank, years of working experience in the library, and monthly salary of library personnel when planning in order to enhance their job performance.

    The main aim of the study is to investigate the mediator roles of locus of control and repetitive thinking in the known relationship between adult attachment patterns and depression, obsessive compulsive disorder (OCD) and social anxiety symptoms. Together with this aim we sought to generate an integrative point of view to these relationships using a cognitive framework. There were 992 participants (661 women, 331 men) for the locus of control model, and 875 participants (581 women, 294 men) for the repetitive thinking model. All of the participants were college students and come from 14 different colleges across 9 different provinces. Participants were evaluated using the Locus of Control Scale, the Repetitive Thinking Questionnaire, the Experiences in Close Relationship Scale-II, the Beck Depression Inventory, the Maudsley Obsessive Compulsive Inventory and the Liebowitz Social Anxiety Scale. Structural Equation Modeling and mediator analysis were applied to the data. The results revealed that there are some partial mediator roles of the locus of control in the relationship between attachment anxiety and depression, OCD and social anxiety for women but there is only an association with depression for men. Regarding repetitive thinking, there are some partial mediator roles between attachment anxiety and depression, OCD and social anxiety for both women and men. These cognitive features do not mediate the relationship between avoidant attachment and psychopathology symptoms for either women or men. This study uncovered that cognitive features are important and incontrovertible variables in the relationship between attachment patterns and psychopathology symptoms.

    The comparison of the locus of control in groups of patients hospitalised due to alcohol withdrawal with and without delirium and analysis of psychotic experiences of patients with delirium. 25 patients with alcohol withdrawal with delirium and 25 without delirium took part in the study. They filled-in the Internal-External (I-E) Locus of Control Scale by Rotter; Multidimensional Health Locus of Control (MHLC) scale; the group with delirium also did the Psychopathological Symptoms Inventory, by Bizoń et al. The mean score in I-E Locus of Control Scale in the group with delirium was more external than in the group without delirium (M = 13.28; SD = 2.762 versus M = 11.64; SD = 2.612; t(48) = -2.157; p = 0.036). Group with delirium had also lower mean score in the dimension of internal control in MHLC, than the group without delirium (M = 24.8; SD = 6.149 versus M = 26.8; SD = 4.648; t(48) = 1.99; p = 0.04). There were no statistically significant differences between the groups in the other subscales. The auditory and visual hallucinations were most common among patients with delirium (84%, 80% respectively, as well as delusions of taking part in not existing events (92%) and persecutory delusions (80%). Psychotic experiences influenced behaviour in nearly 50% of the cases. A more external locus of control may be one of the factors contributing to the development of alcohol delirium. The content of psychotic experiences seems to have impact on the behaviour of many patients with alcohol delirium.

    2016-04-01

    To address the disparities that exist in utilization of mental health services for ADHD among Latino families and to further our understanding of factors that influence parents' decisions to seek treatment for ADHD, the goal of the current study was to examine parental locus of control (PLOC) in a community sample of Latino parents. Specifically, the current study investigated cultural influences on PLOC, as well as the influence of PLOC on help-seeking. Seventy-four primarily Spanish-speaking, Latino parents of school-age children completed measures to assess their help-seeking intentions, PLOC, and cultural orientation. Results indicated that U.S. mainstream orientation was associated with increased feelings of parental control and decreased beliefs in fate/chance and several Latino cultural values were associated with increased beliefs in fate/chance, and decreased feelings of parental efficacy and parental control. In addition, 2 PLOC domains (e.g., parental efficacy and fate/chance) were associated with beliefs that the behaviors of a child with ADHD would go away on their own. Results highlight the need for interventions aimed at modifying parenting behavior to take parents' cultural beliefs and values into account in order to accommodate and engage Latino families more effectively.

    2000-02-01

    Most individuals of Asclepias exaltata are self-sterile, but all plants lack prezygotic barriers to self-fertilization. To determine whether postzygotic rejection of self-fertilized ovules is due to late-acting self-incompatibility or to extreme, early acting inbreeding depression, we performed three diallel crosses among self-sterile plants related as full-sibs. The full-sibs segregated into four compatibility classes, suggesting that late acting self-incompatibility is controlled by a single gene (S-locus). Crosses between plants sharing one or both alleles at the S-locus are incompatible. An additional diallel cross was done among full-sib progeny from a cross of a self-sterile and a self-fertile plant. These progeny grouped into two compatibility classes, and plants within classes displayed varying levels of self-fertility. This suggests that the occasional self-fertility documented in natural pollinations is caused by pseudo-self-fertility alleles that alter the functioning of the S-locus.

  10. CAPRICE family genes control flowering time through both promoting and repressing CONSTANS and FLOWERING LOCUS T expression.

    2015-12-01

    CAPRICE (CPC) and six additional CPC family genes encode R3-type MYB transcription factors involved in epidermal cell fate determination, including Arabidopsis root hair and trichome differentiation. Previously, we reported that the CPC and CPC family genes TRIPTYCHON (TRY) and CAPRICE LIKE MYB3 (CPL3) also affect flowering time. The cpl3 mutant plants flower earlier, with fewer but larger leaves, than do wild type plants, and mutations in CPC or TRY delay flowering in the cpl3 mutant. In this study, we examined flowering time, leaf number, and fresh weight for CPC family gene double and triple mutants. Mutation in ENHANCER OF TRY AND CPC1 (ETC1) shortened the flowering time of the cpl3 single mutant. Mutation in ETC2 significantly reduced fresh weight in the cpl3 mutant. Expression levels of the flowering-related genes CONSTANS (CO) and FLOWERING LOCUS T (FT) were higher in the cpl3 mutant than in wild type plants. The high expression levels of CO and FT in cpl3 were significantly reduced by mutations in CPC, TRY, ETC1, or ETC2. Our results suggest that CPC family genes antagonistically regulate flowering time through CO and FT expression. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    1979-06-01

    This study examined the relationships among generalized expectancy for internal or external control, situational expectancy of control over aversive stimuli, trait anxiety level, and state anxiety reactivity. Seventy-two male subjects, selected from the upper and lower halves of the distributions of scores from the I-E and STAI A-Trait Scales, were randomly assigned to one of three conditions of expectancy of control over electric shock. Repeated measures of state anxiety were taken at three points in the experiment, and subjects were asked to rate the degree of control they expected to have in avoiding shocks. Results, based upon analyses of variance, were interpreted as strongly supportive of the use of the interactionist model in understanding the manner in which personality trait and situational variables interact in the determination of subject expectancies of control and anxiety reactivity.

    1991-01-01

    Understanding similarities between health-related and radon-related knowledge, attitudes, and behaviors may suggest application of effective strategies of radon-related education in targeted populations. A mail survey was returned by 300 randomly selected homeowners in a community at risk for high home radon concentrations (50% response). While 64% were concerned, only 7% tested their homes. The expected association between radon knowledge, radon concern, and information-seeking was identified. In addition, those who tested their homes had greater knowledge and did more information seeking. Health values and radon concern were only weakly related. Environmental concern explained the greatest variance in radon concern (10%). Internal health locus of controls were more likely to have high radon concern. Of the preventive health behaviors, not smoking and seat belt use were the best predictors of variance in radon concern (5%). Segmenting the population is suggested for best educational outcome. Relating information to environmental issues may be helpful. Health-conscious people may need awareness of risks. Issues of self-control and radon testing and reduction may be helpful for some. Synergy between smoke and radon, compounded by smokers lack of concern suggests targeting smokers for education efforts

    Axonal degeneration is responsible for the progression of the irreversible destruction caused by multiple sclerosis (MS) resulting ultimately in permanent disability. The KIF1B protein, a member of the kinesin family, is necessary for axon growth and myelination in vertebrates. In the recent paper, Aulchenko et al. suggested that the rs10492972[C] variant of KIF1B increases susceptibility to MS, but three following replication study didn't confirm this association. We studied the association of the polymorphic locus rs10492972 present in the KIF1B gene with genetic predisposition and its occurrence in clinical presentations of MS patients resident in western Siberia and the Sakha Republic (Yakutia), Russia. rs10492972 has been genotype in 833 samples of MS patient and 689 healthy controls. Distribution of rs10492972 genotypes corresponded with a Hardy-Weinberg distribution in both the MS patient and control groups, with the frequency of the C allele being the same in both groups (33%). Frequencies of occurrence of the genotypes were not shown to be associated with different disease courses or other characteristics of the disease, such as age at onset or duration. A complete meta-analysis of all analogous studies published to date showed that the protective effect of the rs10492972[C] allele is statistically significant (OR=0.95, C.I.95% [0.90-0.99], p=0.02).

    This study explored the contribution of two psychosocial factors, locus of control (LOC) and perceived parenting style, to symptoms of internalizing disorders in children with Tourette syndrome (TS). This contribution was further evaluated in relation to TS severity. Sixty-five children (53 boys, 12 girls) ages 9.0-16.9 years, of normal intelligence, completed questionnaires evaluating their depression and anxiety symptoms, LOC, and maternal parenting style. Their mothers rated TS severity, determined by tic severity, symptoms of attention-deficit hyperactivity disorder (ADHD) and obsessive compulsive symptoms (OCS). Higher rates of symptoms of anxiety and depression were associated with a more external LOC and a more rejecting and controlling parenting style. Additionally, depression correlated significantly with tic severity, ADHD and OCS, whereas anxiety correlated only with ADHD symptoms and OCS, but not with tics. Regression analyses showed that LOC, OCS and ADHD symptoms each significantly contributed to predicting anxiety level, whereas LOC and ADHD symptoms significantly contributed to predicting depression symptoms. Rates of symptoms of anxiety and depression in children with TS are markedly influenced by psychosocial factors, extending beyond the influence of ADHD and OCD, both common comorbid disorders in TS. An internal LOC, which is associated with an accepting and autonomy-granting parenting style, appears to be a protective factor against anxiety and depression.

    The formative years of adolescence are a crucial time for developing eating habits which, amongst other factors, are determined by personality traits. The aim of the study was to estimate eating behaviour in a group of middle school pupils according to gender and locus of control (LOC). Subjects were n = 200 boys and n = 200 girls, aged 14-16 living in the Malopolska region of Poland who were surveyed by questionnaire about their eating habits. A standardised Delta questionnaire, by Drwal, was used to assess LOC. Based on the median from the raw LOC scale scores, groups of boys and girls were thereby identified as having high internal (below the median) or high external (above the median) loci of control. The Chi2 test assessed the dependence between LOC and eating habits using PQStat software ver. 1.4.2.324 adopting values of p differences in certain eating behaviour have been found in middle school students that relate to their gender and LOC. The more rational and appropriate choices were taken by subjects with an internal LOC.

    College-age consumers are one of the groups most highly targeted by credit card marketers. While some college students use their credit cards wisely, others are unable to control their spending. The objective of this study was to investigate differences in attitude toward credit cards and the psychological factors of self-esteem and locus of control among college students who possess one or more credit cards. Attitude was operationalized to include three underlying components: cognitive, affective, and behavioral. We separated credit users into subcategories based on amount of installment debt. Convenience users were defined as those consumers who paid the credit-card balance in full each month. Installment users were classified as consumers who carried a balance month-to-month. Convenience users were compared to mild and heavy installment users to assess significance of differences in attitudinal and psychological factors. There were no significant differences in the psychological factors across the credit-card user groups. In addition, there was a statistically significant difference on each of the attitude components (knowledge/beliefs, affect, and behavior) across user groups; convenience users, mild installment, and heavy installment users.

    Genome-wide association studies (GWAS) have identified more than 100 genetic loci associated with type 2 diabetes (T2D). However, the underlying biological mechanisms for many of these associations remain unknown. GWAS signals close to the glucokinase regulatory protein gene (GCKR) have been reported for lipid and glucose metabolism traits and the risk of T2D. We investigated the regulatory function of an intronic locus at GCKR represented by the lead single nucleotide polymorphism (SNP) rs780094. We used ENCODE project histone modification and transcription factor binding data to determine the regulatory features of a GCKR intronic locus formed by the high linkage disequilibrium rs780094(C/T), rs780095(G/A), and rs780096(G/C) SNPs. Characterization of the transcriptional activity of this region was assessed by luciferase reporter assays in HepG2 cells and mouse primary hepatocytes. ChIP-qPCR was used to determine the levels of haplotype specific transcription factor binding and histone marks. A CRISPR-dCas9 transcriptional activator system and qPCR were used to activate the locus and measure GCKR expression, respectively. Differential haplotype expression was measured from human liver biopsies. The ENCODE data suggest the existence of a liver-specific intragenic enhancer at the locus represented by s780094. We observed that FOXA2 increased the transcriptional activity of this region in a haplotype specific way (CGG > TAC; rs780094, rs780095, and rs780096). In addition, the CGG haplotype showed higher binding to FOXA2 and higher levels of the H3K27Ac histone mark. The epigenetic activation of this locus increased the expression of endogenous GCKR in HepG2 cells, confirming that GCKR is the direct target gene of the enhancer. Finally, we confirmed that the CGG haplotype exhibits higher levels of transcription in human liver. Our results demonstrate the existence of a liver-specific FOXA2-regulated transcriptional enhancer at an intronic T2D locus represented by

    Human papillomavirus (HPV) can induce cervical intraepithelial neoplasias (CIN) grades 1, 2 and 3. Untreated, these lesions may progress to cervical cancer (CC) which is the third most common cancer in women worldwide. HLA-G plays an immunotolerant role in the immune response. The aim of this study was to characterize the configuration of SNPs located at the distal promoter of HLA-G in patients with CIN2 and CIN3 and control women. The study sample was composed of 207 women as follows: 73 diagnosed with CIN2 lesions, 56 with CIN3 and 78 healthy control women. Genotyping was performed by sequence base typing. Eleven haplotype configurations subdivided in two main haplogroups (H1dist and H2dist), were characterized and compared between patients and controls. The haplotypes H1.1Dist (GAGAACGC) and H2.1Dist (AGGTACAC) were more frequent in Euro-Descendants as well as in Brazilian Mixed. Nevertheless, the haplotype H2.1Dist standed out as a susceptibility haplotype in Brazilian Mixed patients while the H1.1Dist presented a protector effect in this same ethnic group. Whether such LCR haplotype configurations can impact on HLA-G gene expression levels in women who developed cervical intraepithelial neoplasia is still unknown and it is of utmost importance that more investigation on this field be pursued.

    Postpartum contraception helps reduce unintended pregnancy and space births to improve maternal and child health. This study explored women's perceptions of contraceptive choice during the postpartum period in the context of locus of control and trust in healthcare providers. Researchers conducted six focus groups with 47 women, ages 18-39, receiving postpartum care at an outpatient clinic. Techniques from grounded theory methodology provided an inductive approach to analysis. HyperRESEARCH 3.5.2 qualitative data analysis software facilitated a constant-comparative coding process to identify emergent themes. Participants expressed a preference for relationship-centered care, in which healthcare providers listened, individualized their approach to care through rapport-building, and engaged women in shared decision-making about contraceptive use through open communication, reciprocity, and mutual influence. Conflicting health messages served as barriers to uptake of effective contraception. While participants trusted their healthcare provider's advice, many women prioritized personal experience and autonomy in decisions about contraception. Providers can promote trust and relationship-centered care to optimize contraceptive uptake by listening, exploring patient beliefs and preferences about contraception and birth spacing, and tailoring their advice to individuals. Results suggest that antenatal contraceptive counseling should incorporate information about effectiveness, dispel misconceptions, and engage patients in shared decision-making.

  8. Androecious Genotype ‘Male 8’ Carries the CPCNA Gene Locus Controlling Natural Deastringency of Chinese PCNA Persimmons

    Full Text Available The androecious genotype of Diospyros spp. ‘Male 8’, which is distributed in Dabie Mountain area of the central China, was probably derived from the hybrids or natural variation of Chinese pollination constant and non-astringent (CPCNA persimmon. Its application potential as the breeding parent of pollination constant and non-astringent (PCNA is undefined. In this study, we identified the astringency type of a hybrid individual (H8-2 derived from the cross between ‘Huashi 1’ (pollination variant and astringent, PVA and ‘Male 8’. Through comparison with the known genotypes of CPCNA, Japanese PCNA (JPCNA and non-PCNA, the results of soluble/insoluble tannin content and tannin cell size measure showed that H8-2 was a PCNA genotype with the characteristic of natural deastringency of CPCNA. According to the currently known genetic features of PCNA persimmon, a new individual of PCNA may be generated in F1 population when two JPCNA genotypes are crossed or when the CPCNA genotype is used as a parent. Thus, the study verifies that androecious genotype ‘Male 8’ carries the dominant gene locus that controls the non-astringent trait of CPCNA, indicating its potential to be used as pollen donor for the genetic improvement of PCNA persimmon.

    Full Text Available Orientation: The role of traits as a determinant of states has resulted in researchers closely examining their potential for enhancing work behaviour. This is achieved through the examination of the trait and state perspectives. Research purpose: This research sought to determine the relationship between work locus of control (WLOC and psychological capital (PsyCap, with the objective of increasing alertness on the trait and state approach. Motivation for the study: The current study investigated the role of traits and states in contributing to the positive psychology arena within the recruitment industry. Research approach, design and method: This longitudinal research design involved 425 middle managers at Time 1 (T1, at both supervisory and specialist levels, and 190 middle managers at supervisory levels at Time 2 (T2. This longitudinal study used a biographical, WLOC and PsyCap questionnaires. Main findings: The findings indicated that WLOC has predictive value for PsyCap: a statistically significant and practical relationship was established between WLOC and PsyCap at T1 and T2. However, the multiple regression analysis results were not consistently demonstrated over time. Practical managerial implications: Understanding the role of personality traits and psychological states can provide managers with additional means of increasing employee efficiency through improving work processes such as recruitment and selection. Contributions/value-add: The recruitment and other industries are encouraged to utilise a strength-based approach to enhance work performance through selection processes that incorporate traits and states to further increase organisational competitiveness.

    The human β-globin locus control region (LCR) is essential for high-level expression of human var-epsilon-, γ-, and β-globin genes. Developmentally stable DNase I hypersensitive sites (designated HS) mark sequences within this region that are important for LCR activity. A 1.9-kilobase (kb) fragment containing the 5' HS 2 site enhances human β-globin gene expression 100-fold in transgenic mice and also confers position-independent expression. To further define important sequences within this region, deletion mutations of the 1.9-kb fragment were introduced upstream of the human β-globin gene, and the constructs were tested for activity in transgenic mice. Although enhancer activity was gradually lost with deletion of both 5' and 3' sequences, a 373-base-pair (BP) fragment retained the ability to confer relative position-independent expression. Three prominent DNase I footprints were observed in this region with extracts from the human erythroleukemia cell line K-562, one of which contained duplicated binding sites for transcription factor AP-1 (activator protein 1). When the 1.9-kb fragment containing an 19-bp deletion of the AP-1 binding sites was tested in transgenic mice, enhancer activity decreased 20-fold but position-independent expression was retained

    While longitudinal posttraumatic stress responses are known to be heterogeneous, little is known about predictors of those responses. We investigated if locus of control (LOC) and coping style are associated with long-term PTSD-trajectories after exposure to combat. Six hundred and seventy five Israeli soldiers with or without combat stress reaction (CSR) from the Lebanon war were assessed 1, 2, and 20 years after the war. Combat exposure, LOC, and coping style were then investigated as covariates of the trajectories of resilience, recovery, delayed onset, and chronicity. Symptomatic trajectories in the CSR and the non-CSR group were significantly associated to varying degrees with perceived life threat during combat (ORs: 1.76-2.53), internal LOC (0.77-0.87), emotional coping style (0.28-0.34), and low use of problem-focused coping (2.12-3.11). In conclusion, assessment of LOC and coping can aid prediction of chronic PTSD outcomes of combat exposure. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Spirituality seems to be an important cultural factor for African American women when thinking about their health. It is, however, not clear how spiritual health locus of control (SLOC impacts health-related outcomes in the context of health message processing models, such as the Extended Parallel Process and the Risk Perception Attitude framework. Using a survey of African American and Caucasian women in the context of breast cancer, the role of SLOC and its interactions with perceived efficacy and risk was examined on four health outcomes—message acceptance, talking about breast cancer, information seeking, and behavioral intentions. For African American women, SLOC had a positive impact for talking about breast cancer through an interaction with risk and efficacy such that women high in both SLOC and perceived efficacy, but low in perceived risk were more likely to talk about breast cancer than when efficacy was low. However, high SLOC exacerbated the negative effects of efficacy on talking about breast cancer regardless of the risk level for Caucasian women. SLOC also had a positive influence on attending to breast cancer information in the media for African American women. SLOC played no role in attending to breast cancer information for Caucasian women. Interestingly, SLOC played no role for African American women on behavioral intentions, however, it worked to decrease behavioral intentions for Caucasian women when risk was high.

  14. Identification of Orch3, a locus controlling dominant resistance to autoimmune orchitis, as kinesin family member 1C.

    Full Text Available Experimental autoimmune orchitis (EAO, the principal model of non-infectious testicular inflammatory disease, can be induced in susceptible mouse strains by immunization with autologous testicular homogenate and appropriate adjuvants. As previously established, the genome of DBA/2J mice encodes genes that are capable of conferring dominant resistance to EAO, while the genome of BALB/cByJ mice does not and they are therefore susceptible to EAO. In a genome scan, we previously identified Orch3 as the major quantitative trait locus controlling dominant resistance to EAO and mapped it to chromosome 11. Here, by utilizing a forward genetic approach, we identified kinesin family member 1C (Kif1c as a positional candidate for Orch3 and, using a transgenic approach, demonstrated that Kif1c is Orch3. Mechanistically, we showed that the resistant Kif1c(D2 allele leads to a reduced antigen-specific T cell proliferative response as a consequence of decreased MHC class II expression by antigen presenting cells, and that the L(578 → P(578 and S(1027 → P(1027 polymorphisms distinguishing the BALB/cByJ and DBA/2J alleles, respectively, can play a role in transcriptional regulation. These findings may provide mechanistic insight into how polymorphism in other kinesins such as KIF21B and KIF5A influence susceptibility and resistance to human autoimmune diseases.

    The purpose of this study was to identify the relationship between eating disorders, physical symptoms, depression and health locus of control. The research design was a descriptive study done by using a constructive self-report questionnaire. A total of 464 elementary school girls were measured. The instrument was a constructive questionnaire that consisted 136 items. The subjects were divided into 4 groups according to the Body Mass Index (BMI). Data analysis was done by SPSS/WIN Programs using frequency, percentage, mean, SD, ANOVA, Pearson correlation coefficient, and stepwise multiple regression. The score of eating disorders differed significantly by BMI : the score was highest in the group of obese students(F=4.208, P=.015). Stepwise multiple regression analysis revealed that the most powerful predictor of eating disorders was BMI. These results indicate that Korean elementary school girls need more education and counseling on diet. Also, we should take systematic efforts to reestablish the social standard of beauty to promote normal growth development.

    Synthetic regulatory proteins such as tetracycline (tet)-controlled transcription factors are potentially useful for repression as well as ectopic activation of endogenous genes and also for probing their regulatory mechanisms, which would offer a versatile genetic tool advantageous over conventional gene targeting methods. In this study, we provide evidence supporting this concept using Cd4 as a model. CD4 is expressed in double-positive and CD4 cells but irreversibly silenced in CD8 cells. The silencing is mediated by heterochromatin established during CD8 lineage development via transient action of the Cd4 silencer; once established, the heterochromatin becomes self-perpetuating independently of the Cd4 silencer. Using a tet-sensitive Cd4 allele harboring a removable Cd4 silencer, we found that a tet-controlled repressor recapitulated the phenotype of Cd4-deficient mice, inhibited Cd4 expression in a reversible and dose-dependent manner, and could surprisingly replace the Cd4 silencer to induce irreversible Cd4 silencing in CD8 cells, thus suggesting the Cd4 silencer is not the (only) determinant of heterochromatin formation. In contrast, a tet-controlled activator reversibly disrupted Cd4 silencing in CD8 cells. The Cd4 silencer impeded this disruption but was not essential for its reversal, which revealed a continuous role of the silencer in mature CD8 cells while exposing a remarkable intrinsic self-regenerative ability of heterochromatin after forced disruption. These data demonstrate an effective approach for gene manipulation and provide insights into the epigenetic Cd4 regulatory mechanisms that are otherwise difficult to obtain.

    Directory of Open Access Journals (Sweden)

    Full Text Available Hypersensitive site 5 (5'HS5 of the beta-globin Locus Control Region functions as a developmental stage-specific border in erythroid cells. Here, we have analyzed the role of 5'HS5 in the three dimensional organization of the beta-gene locus using the Chromatin Conformation Capture (3C technique. The results show that when 5'HS5 is deleted from the locus, both remote and internal regulatory elements are still able to interact with each other in a three-dimensional configuration termed the Active Chromatin Hub. Thus, the absence of 5'HS5 does not have an appreciable effect on the three dimensional organization of the beta-globin locus. This rules out models in which 5'HS5 nucleates interactions with remote and/or internal regulatory elements. We also determined the binding of CTCF, the only defined insulator protein in mammalian cells, to 5'HS5 by using chromatin immunoprecipitation (ChIP assays. We detect low levels of CTCF binding to 5'HS5 in primitive erythroid cells, in which it functions as a border element. Surprisingly, we also observe binding levels of CTCF to 5'HS5 in definitive erythroid cells. Thus, binding of CTCF to 5'HS5 per se does not render it a functional border element. This is consistent with the previous data suggesting that CTCF has dual functionality.

  20. Autoregulatory Feedback Controls Sequential Action of cis-Regulatory Modules at the brinker Locus

    2013-01-01

    Summary cis-regulatory modules (CRMs) act sequentially to regulate temporal expression of genes, but how the switch from one to the next is accomplished is not well understood. To provide insight, here we investigate the cis-regulatory system controlling brinker (brk) expression in the Drosophila embryo. Two distally located CRMs support expression at different times, while a promoter-proximal element (PPE) is required to support their action. In the absence of Brk protein itself or upon mutagenesis of Brk binding sites within the PPE, the late-acting CRM, specifically, is delayed. This block to late-acting CRM function appears to be removed when the early-acting CRM is also deleted. These results demonstrate that autoregulatory feedback is necessary for the early-acting CRM to disengage from the promoter so that the late-acting CRM may act. Autoregulation may be a commonly used mechanism to control sequential CRM action necessary for dynamic gene expression throughout the course of development. PMID:24044892
