A conceptual framework is advanced that assumes that psychological symptoms emerge within multiple contexts, such as the workplace, and are influenced by the interplay of individual and situational risk and protective factors over time. This framework was utilized to examine the impact of work and work-family role stressors, coping, and work-related social support on psychological symptoms among 239 female, secretarial employees in the USA, using both cross-sectional and longitudinal structural equation models. Work stressors and avoidance coping were viewed as risk factors, and active coping and social support as protective factors. Work stressors contributed substantially to increased symptoms, primarily through a direct pathway in the cross-sectional model, but also indirectly to both Time 1 and Time 2 symptoms (4 months later) via pathways through active and avoidance coping. In both models, avoidance coping also predicted increased symptoms. Avoidance coping also served to partially mediate the relationship between work stressors and symptoms in the cross-sectional model, but not in the longitudinal model. Active coping was related to fewer psychological symptoms in both models, thereby reducing the negative effect of work stressors on symptoms. Likewise, work-related social support served an indirect protective function by contributing to lower levels of reported work stressors and greater use of active coping. Work stressors but not active coping mediated the relationship between social support and symptoms. Implications for future research and workplace interventions are discussed. 相似文献

This study analyses the influence of chronic occupational stress on cardiovascular reactivity (heart rate [HR] and blood pressure [BP] elevation from baseline to maximal challenge) during a standard mental stress test (modified version of the STROOP colour word interference test). The test was applied to a sample of 190 healthy male blue-collar workers at the end of a regular working day. Our research hypothesis was based on the assumption that sustained autonomic activation due to chronic occupational stress may reduce cardiovascular responsiveness to challenge: workers defined by high level of chronic occupational stress exhibited lower maximal HR and BP elevations under challenge as compared to workers with low levels of stress. Three distinct indicators of occupational stress were derived from structured interviews: 'cumulative workload', 'worsening of job conditions', and 'high demand and low job security'. Statistical analysis, using ANOVA, showed that all main effects of chronic stress were in the expected direction (6 of 9 effects were statistically significant at the 0'05 level). These effects remained stable after adjusting for age, hypertensive status, physiological baseline level, cigarette smoking, test performance, and individual style of coping. In summary, cardiovascular reactivity under experimental challenge is modulated by an individual's experience of chronic occupational stress. 相似文献

Alarmed by the large numbers of high school-age youth who are disengaged at school and leaving high school without a diploma or the important skills for the workplace, policymakers and youth advocates are beginning to see high school after-school as the new frontier in after-school programming. Although older youth represent a sizable percentage of American students, they garner only a small fraction of the federal, state, and local investments for after-school programs. This chapter reviews the insights and lessons learned from three after-school initiatives that have shown success in attracting high school students to their programs and engaging them in meaningful activities to support their success in school and transition to early adulthood: the After School Safety and Education for Teens, After School Matters, and the After-School Corporation. Emerging from these pioneering efforts are some promising practices and program models that can guide the development of future after-school programs, but not without the help of policymakers and funders, both public and private. 相似文献

This administrative data analysis examined substance use and mental health severity among a sample of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) individuals receiving residential treatment for an alcohol or drug use disorder. LGBTQ were statistically compared to heterosexual patients on a number of variables, including frequency and amount of pretreatment alcohol use, frequency of pretreatment illicit drug use, co-occurring Axis I mental health diagnoses, and past history of physical or sexual abuse. LGBTQ patients exhibited significantly greater severity on nearly all variables, suggesting a strong relationship between clinical severity and being a sexual minority. This study also found a relationship between patient gender and the pattern of differences between LGBTQ and heterosexual patients. These results replicate and extend those of studies examining LGBTQ in the general population and suggest opportunities for development of alcohol/drug treatment approaches that address the unique needs of LGBTQ. 相似文献

The present study was conducted to identify game parameters that would reduce the risk of abuse of video lottery terminals (VLTs) by pathological gamblers, while exerting minimal effects on the behavior of non-pathological gamblers. Three manipulations of standard VLT game features were explored. Participants were exposed to: a counter which displayed a running total of money spent; a VLT spinning reels game where participants could no longer stop the reels by touching the screen; and sensory feature manipulations. In control conditions, participants were exposed to standard settings for either a spinning reels or a video poker game. Dependent variables were self-ratings of reactions to each set of parameters. A set of 2(3) × 2 × 2 (game manipulation [experimental condition(s) vs. control condition] × game [spinning reels vs. video poker] × gambler status [pathological vs. non-pathological]) repeated measures ANOVAs were conducted on all dependent variables. The findings suggest that the sensory manipulations (i.e., fast speed/sound or slow speed/no sound manipulations) produced the most robust reaction differences. Before advocating harm reduction policies such as lowering sensory features of VLT games to reduce potential harm to pathological gamblers, it is important to replicate findings in a more naturalistic setting, such as a real bar. 相似文献
