In this meta‐analytic review, we examined the relation between natural mentoring and youth outcomes in four domains: academic and vocational functioning, social‐emotional development, physical health, and psychosocial problems. Natural mentoring relationships are thought to foster positive youth development and buffer against the risks associated with the tumultuous years of adolescence. Two separate meta‐analyses were conducted on the presence of a natural mentor and the quality of the natural mentoring relationship, including thirty studies from 1992 to present. The findings indicated that the presence of a natural mentor was significantly associated with positive youth outcomes (r = .106). A larger effect size was found for the quality of the natural mentoring relationship in terms of relatedness, social support, and autonomy support (r = .208). The largest effect sizes were found for social‐emotional development and academic and vocational functioning. Risk‐status (e.g., teenage mothers, homeless youth, youth in foster care, and youth of alcoholic parents) did not moderate the relation between presence and quality of natural mentoring relationships and youth outcomes, which may indicate that natural mentors are generally beneficial for all youth regardless of risk‐status. Implications for theory and practice concerning the quality of the natural mentoring relationship are discussed.  相似文献

The stigma surrounding mental ill‐health is an important issue that affects likelihood of diagnosis and uptake of services, as those affected may work to avoid exposure, judgment, or any perceived loss in status associated with their mental ill‐health. In this study, we drew upon social identity theory to examine how social group membership might influence the stigma surrounding mental ill‐health. Participants from two urban centers in Ireland (= 626) completed a survey measuring stigma of mental health, perceived social support as well as identification with two different social groups (community and religion). Mediation analysis showed that subjective identification with religious and community groups led to greater perceived social support and consequently lower perceived stigma of mental ill‐health. Furthermore, findings indicated that high identification with more than one social group can lead to enhanced social resources, and that identification with a religious group was associated with greater community identification. This study thus extends the evidence base of group identification by demonstrating its relationship with stigma of mental ill‐health, while also reinforcing how multiple identities can interact to enhance social resources crucial for well‐being.  相似文献

Sleep problems are prevalent among Veterans. Left untreated, such problems may elevate psychological distress and increase risk of subsequent mental health disorders. Psychological resilience may buffer against negative psychological outcomes, yet the relationship between sleep and resilience has not been studied. This study explored poor sleep, resilience, and psychological distress using questionnaires collected as part of the Study of Post-Deployment Mental Health. Participants (N = 1,118) had served in the US military since September 11, 2001, had one or more overseas deployments, and were free from a past-month DSM-defined mental health disorder. Hierarchical linear regression was used to examine the association between poor sleep quality (Pittsburgh Sleep Quality Index total score) and psychological distress (Global Symptom Index; Symptom Checklist-90-R), controlling for demographic and health characteristics. Moderation analyses tested for a potential buffering effect of resilience (Connor-Davidson Resilience Scale). Poor sleeping Veterans had worse physical and psychological health, lower resilience, and endorsed more lifetime traumatic events. Poor sleep was associated with greater psychological distress controlling for health and demographic characteristics. Both resilience factors—adaptability and self-efficacy—had significant buffering effects on the relationship between poor sleep and psychological distress, suggesting that resilience may protect against negative outcomes in poor sleepers. Additional research is warranted to better understand the relationships between sleep, resilience, and psychological distress. Such research may inform pertinent prevention efforts, including interventions that improve sleep, enhance resilience, and protect against incident mental health diagnoses.  相似文献

Feelings of vigor are associated with positive consequences in the work place but these relationships have not yet been assessed in a high-risk occupational context. The current study assessed the relationships between feelings of vigor on physical health symptoms, functional impairment, and depression symptoms among U.S. service members who recently returned from a combat deployment. U.S. service members were asked to complete questionnaires at 2 time points. Significant positive correlations were found between combat experiences and the 3 outcomes. Significant negative correlations were found for feelings of vigor and each outcome. Regression analyses indicated a significant effect for feelings of vigor such that higher feelings of vigor at Time 1 predicted better physical health and fewer depression symptoms at Time 2. There was no significant effect for functional impairment. Results demonstrate the potential importance of maintaining or improving feelings of vigor throughout the work day, especially for those with high risk occupations.  相似文献

Abstract

The goal of therapy is typically to improve clients’ self-management of their problems, not only during the course of therapy but also after therapy ends. Although it seems obvious that therapists are interested in improving clients’ self-management, the psychotherapy literature has little to say on the topic. This article introduces Leventhal’s Common-Sense Model of Self-Regulation, a theoretical model of the self-management of health, and applies the model to the therapeutic process. The Common-Sense Model proposes that people develop illness representations of health threats and these illness representations guide self-management. The model has primarily been used to understand how people self-manage physical health problems, we suggest it may also be useful to understand self-management of mental health problems. The Common-Sense Model’s strengths-based perspective is a natural fit for the work of counseling psychologists. The model has important practical implications for addressing how clients understand mental health problems over the course of treatment and self-manage these problems during and after treatment.  相似文献

Objective: Negative feelings about condoms are a key barrier to their use. Using the behavioural affective associations model, we examined the joint effects of affective associations and cognitive beliefs about condoms on condom use.

Design: In Study 1 (N = 97), students completed measures of their affective associations and cognitive beliefs about sex and condoms, sexual activity and condom use. In Study 2 (N = 171), a measure of behavioural intentions and condom selection task were added.

Main outcome measures: Condom use measured in Study 1 as (1) current condom use, and (2) willingness to use condoms; in Study 2 as: (1) behavioural intentions, (2) number of condoms selected.

Results: Affective associations with sex and condoms were behaviour-specific, were directly associated with the respective behaviour, and mediated the relations of cognitive beliefs to behaviour, ps < .05. In Study 2, affective associations were associated with behavioural intentions and the number of condoms selected, ps < .05; cognitive beliefs were indirectly associated with these outcomes through affective associations, indirect effects: ps < .05.

Conclusions: Affective associations are a behaviour-specific and proximal predictor of condom use, mediating the effect of cognitive beliefs, suggesting they may be a particularly viable intervention target.  相似文献

Objective: Worries about health threatening effects of potential health hazards of modern life (e.g. electric devices and pollution) represent a growing phenomenon in Western countries. Yet, little is known about the causes of this growing special case of affective risk perceptions termed Modern Health Worries (MHW). The purpose of this study is to examine a possible role of biased media reports in the formation of MHW.

Design: In two experiments, we investigated whether typical television reports affect MHW. In Study 1, 130 participants were randomly assigned to a film on idiopathic environmental intolerance (IEI) or a control film about cystic fibrosis. In Study 2, 82 participants were randomly assigned to either a film on the dangers of electromagnetic fields or a control condition.

Main outcome measures: Increases in MHW after sensational media reports.

Results: In Study 1, only participants high on the personality trait of absorption revealed increased MHW after watching the IEI film. In Study 2, specifically worries about radiation were found to be elevated after watching the film on the dangers of electromagnetic fields compared to the control film.

Conclusion: The results of both studies reveal a significant and specific influence of sensational short mass media reports on MHW. The influence of potential moderators such as absorption remains to be clarified.  相似文献

Objective: The prevailing focus regarding eating behaviour is on restriction, concern, worry and pathology. In contrast, the purpose of the present studies was to focus on a positive relationship with eating in non-clinical samples from Germany, the USA and India.

Design: In Study 1, the Positive Eating Scale (PES) was tested and validated in a large longitudinal sample (T1: N = 772; T2: N = 510). In Study 2, the PES was tested in online samples from the USA, India and Germany (total N = 749).

Main Outcome Measures: Health risk status was measured in Study 1 with objective health parameters (fasting serum glucose, triglycerides, high-density lipoprotein cholesterol, blood pressure, waist circumference, BMI).

Results: Study 1 revealed acceptable psychometric properties of the PES, internal consistency (α = .87), as well as test–retest reliability after six months (r = .67). Importantly, a positive relationship with eating was associated with decreased health risk factors six months later. In Study 2, the structure of the PES was confirmed for German, Indian and US-American adults, suggesting validity across remarkably different eating environments.

Conclusion: A positive relationship with eating might be a fruitful starting point for prevention and intervention programmes promoting physical and psychological health.  相似文献

Objective: To examine whether rates of change in perceived control are predictive of cardiovascular disease (CVD) incidence across adulthood and old age.

Design: We used the PATH Through Life Project (n = 7103, M = 40, SD = 16; 52% women), a longitudinal panel survey that encompasses three cohorts at Time 1, ages 20–24, 40–44 and 60–64, who have been assessed three times at four-year intervals.

Method: We examined whether rates of change in perceived control were associated with CVD incidence over 8 years of time, over and above that of baseline levels of perceived control and known risk factors for CVD.

Main Outcome Measures: Self-reported CVD incidence.

Results: Increases in perceived control over time were associated with decreased likelihood of 8-year incidence of CVD and these effects were independent of socio-demographics, covariates and baseline levels of perceived control. The effects were consistent across young adulthood, midlife and old age and for men and women.

Conclusions: Findings demonstrate the importance of changes in perceived control as a predictor of CVD incidence across adulthood and old age. We suggest future research using mediation analysis to test reverse causality and mechanisms underlying the effects of perceived control on CVD incidence.  相似文献
