The purpose of this study is twofold: (1) to compare stress appraisals, coping strategies, social resources, and burnout at work between social workers, psychologists and nurses; and (2) to assess the effectiveness of appraisals and support in reducing burnout and enhancing effective coping strategies. Questionnaires containing assessments of work stress appraisals, coping strategies used to deal with problems at work, and social support at work, as well as burnout measures of exhaustion, depersonalization, and accomplishment were completed by 249 female professionals (age range 25-61). No differences were observed between the three professions on most psychological measures, except for the depersonalization outcome of burnout, which was significantly lower among psychologists than among nurses or social workers. High challenge/control appraisal of the job was directly related to all burnout outcomes, contributing to less exhaustion and depersonalization and to more personal accomplishment. The challenge/control appraisal was also negatively associated with emotion-focused coping. By comparison, the stress/load appraisal contributed to more exhaustion at work, while emotion-focused coping contributed to higher depersonalization. Social support was associated with higher challenge/control appraisal, with the latter mediating support effects on burnout. These data suggest that the perception of challenge/control in one's work may be an important factor in preventing work burnout in the three professions tested in the study.

The research investigated the associations of social and affective factors with risk‐taking in male and female adolescents. A sample of 269 Israeli adolescents completed questionnaires measuring frequency of involvement in risk‐taking behaviours, relationships with parents, orientation towards peer group, depressive mood, and aggressive behaviour. Correlations and multiple regression analyses showed that risk behaviour among male adolescents was mainly related to orientation towards peer group, while for female adolescents relationships with parents was the prominent factor in risk behaviour. The parental factor also contributed to the depressive mood of both genders in the sample. However, depressive mood showed only a weak association with risk taking. These results underscore the differential associations of relationships with parents vs. peers among adolescent boys and girls, respectively, in regard to risk taking.

Sexual dimorphisms are responsible for profound metabolic differences in health and behavior. Whether males and females react differently to environmental cues, such as solar ultraviolet (UV) exposure, is unknown. Here we show that solar exposure induces food-seeking behavior, food intake, and food-seeking behavior and food intake in men, but not in women, through epidemiological evidence of approximately 3,000 individuals throughout the year. In mice, UVB exposure leads to increased food-seeking behavior, food intake and weight gain, with a sexual dimorphism towards males. In both mice and human males, increased appetite is correlated with elevated levels of circulating ghrelin. Specifically, UVB irradiation leads to p53 transcriptional activation of ghrelin in skin adipocytes, while a conditional p53-knockout in mice abolishes UVB-induced ghrelin expression and food-seeking behavior. In females, estrogen interferes with the p53–chromatin interaction on the ghrelin promoter, thus blocking ghrelin and food-seeking behavior in response to UVB exposure. These results identify the skin as a major mediator of energy homeostasis and may lead to therapeutic opportunities for sex-based treatments of endocrine-related diseases.
