Despite several suggestions that peer support is empowering for persons with mental health problems because of its mutual nature, few studies have empirically studied the role of its reciprocity and the effects on subjective well-being of clients from mainstream mental health care settings. Using data of 628 users of vocational and psychiatric rehabilitation centers ( N  = 51) in Flanders, the effects of the reciprocity of peer support on self-esteem and self-efficacy are explored by testing hypotheses derived from the theories of exchange, social capital, equity, and self-esteem enhancement. Results show that providing peer support is more beneficial than receiving it. One conclusion is that the net beneficial effects of receiving support from peers are overestimated.  相似文献

The authors examined White and Black participants' emotional, physiological, and behavioral responses to same-race or different-race evaluators, following rejecting social feedback or accepting social feedback. As expected, in ingroup interactions, the authors observed deleterious responses to social rejection and benign responses to social acceptance. Deleterious responses included cardiovascular (CV) reactivity consistent with threat states and poorer performance, whereas benign responses included CV reactivity consistent with challenge states and better performance. In intergroup interactions, however, a more complex pattern of responses emerged. Social rejection from different-race evaluators engendered more anger and activational responses, regardless of participants' race. In contrast, social acceptance produced an asymmetrical race pattern--White participants responded more positively than did Black participants. The latter appeared vigilant and exhibited threat responses. Discussion centers on implications for attributional ambiguity theory and potential pathways from discrimination to health outcomes.  相似文献

Ecological validity of neuropsychological assessment includes the ability of tests to predict real-world functioning and/or covary with brain structures. Studies have examined the relationship between adaptive skills and test performance, with less focus on the association between regional brain volumes and neurobehavioral function in healthy children. The present study examined the relationship between temporal lobe gray matter volumes and performance on two neuropsychological tests hypothesized to measure temporal lobe functioning (visual perception-VP; peabody picture vocabulary test, third edition-PPVT-III) in 48 healthy children ages 5-18 years. After controlling for age and gender, left and right temporal and left occipital volumes were significant predictors of VP. Left and right frontal and temporal volumes were significant predictors of PPVT-III. Temporal volume emerged as the strongest lobar correlate with both tests. These results provide convergent and discriminant validity supporting VP as a measure of the "what" system; but suggest the PPVT-III as a complex measure of receptive vocabulary, potentially involving executive function demands.  相似文献

Background Family physicians (FPs) are increasingly involved in delivering genetic services. Familiarization with aspects of genetic counseling may enable FPs to help patients make informed choices. Purpose Exploration of interactive role-play as a means to raise FPs’ awareness of the process and content of genetic counseling. Methods FPs attending two large Canadian family medicine conferences in 2005 were eligible—93 participated. FPs discussed a case during a one-on-one session with a genetic counselor. Evaluation involved pre and post intervention questionnaires Results FPs’ baseline genetic knowledge was self-rated as uniformly poor. Baseline confidence was highest in eliciting family history and providing psychosocial support and lowest in discussing risks/benefits of genetic testing and counseling process. Post-intervention, 80% of FPs had better appreciation of family history and 97% indicated this was an effective learning experience. Conclusions Role-play with FPs is effective in raising awareness of the process and content of genetic counseling and may be applied to other health disciplines.

Female fragile X premutation carriers are at ∼10-fold increased risk of premature ovarian failure (follicle stimulating hormone >40 mIU/mL, amenorrhea, age <40). A milder degree of premature ovarian aging (diminished ovarian reserve, where follicle stimulating hormone levels are typically 10–20 mIU/mL) results in infertility. Approximately 10% of fertility clinic patients have this diagnosis. A cohort of 20 women diagnosed with diminished ovarian reserve provided a blood specimen (confidential results), and completed structured questionnaires that assessed emotional reactions to potentially being a premutation carrier (pretest questionnaire, n = 20) and the posttest known carrier status (3 month follow-up questionnaire, n = 18 non-carriers). Responses were measured using 9-point scales, and analyzed with Fisher exact and Wilcoxon exact tests. While most participants did not view fragile X premutations as a serious medical condition, perceptions of seriousness were positively correlated with anger and regret about not knowing sooner of the potential association of these premutations with infertility. Overall, when women (pretest) imagined themselves as carriers, their self-esteem and Health Orientation Scale responses were unchanged with the exception of feeling more afraid (p = 0.004). Despite strongly wishing for negative test results, they were glad to know there might be a medical explanation for their infertility.

This article presents reflections on the seven articles included in this special series. The classification of school attendance problems (SAPs) based on structured checklists of SAP types (school refusal, truancy, school withdrawal, and school exclusion) together with functional analysis opens the way for establishing norms and social referents. We discuss how authorized nonattendance can also be problematic if it is persistent, and that it is important to take this type of SAP into account if the field is to effectively understand and respond to the complex range of bio-psycho-socio-cultural determinants of absenteeism. We highlight other gaps in the current literature, one of which is the lack of attention to evidence-based prevention and early intervention strategies. Avenues for future research are suggested, with emphasis on the need for pragmatic approaches to address the complexities of SAPs. Promising work is beginning to address the SAPs that are prevalent in special populations such as those with autism spectrum disorder. Overall, our reflections highlight the incremental changes that have characterized the field, exemplified by this series of articles, and the promise of transformational change in tackling the major challenge of SAPs as research in the field continues.  相似文献

Pornography use, preference for “porn‐like” sex, masturbation, and sexual and relationship satisfaction were assessed among two samples of men (NStudy 1 = 326, NStudy 2 = 335). Frequent pornography use was associated with sexual dissatisfaction, greater preference for porn‐like sex, and more frequent masturbation in both studies. Pornography use was associated with relationship dissatisfaction in Study 2 only. The data did not support the notion that pornography negatively impacts sexual or relationship satisfaction via preference for porn‐like sex. In fact, it may bolster sexual satisfaction by promoting sexual variety. The data were consistent with a model in which pornography negatively, indirectly affects sexual and relationship satisfaction via masturbation frequency. Pornography use may have multiple opposing influences on sexual satisfaction.  相似文献

Delay discounting refers to the tendency of individuals to subjectively devalue rewards that are to be received in the future, with high rates of delay discounting being associated with a variety of maladaptive life outcomes (e.g., unhealthy dietary and exercise behaviors). The current study explored the psychological and social processes involved in adult age‐related differences in delay discounting of monetary rewards. Younger adults exhibited higher levels of delay discounting than older adults. This increased level of patience in older adults was found whether smaller‐sooner rewards were to be received immediately or in the future. However, there was an interaction with reward magnitude, whereby younger adults exhibited higher levels of delay discounting for smaller reward magnitudes but not larger reward magnitudes. Social influence on delay discounting was investigated by having participants complete three phases of the delay‐discounting task: an individual precollaboration phase, a collaboration phase in age‐group‐matched dyads, and an individual postcollaboration phase. A convergence effect was observed in that dyad members' postcollaboration choices were significantly more similar compared to their baseline choices during the precollaboration phase. Moreover, levels of convergence were comparable between younger and older adults, suggesting age invariance in social influence on delay discounting. The current results demonstrate a degree of malleability in delay discounting that extends into older adulthood, making interventions targeting the construct a promising avenue for future research.  相似文献

In this research, we investigate the impact of significant life experiences on intertemporal decisions among young adults. A series of experiments focus specifically on the impact of experiencing the death of a close other by cancer. We show that such an experience, which bears information about time, is associated with making decisions that favor the long-term future over short-term interests (Studies 1 and 2). Underlying this effect appears to be increased salience and concreteness regarding one’s future life course, shifting focus away from the present toward the long run (Studies 3 and 4). Finally, we explore the shift caused by a cancer death of a public figure and examine its stability over time (Study 5). Implications for research on intertemporal decision making and the impact of life events on perceptions and preferences are discussed.  相似文献
