This study examined the mediated and moderated effects of a universal family-focused preventive intervention, delivered during young adolescence, on internalizing symptoms assessed in young adulthood. Sixth grade students (N=446; 52% female; 98% White) and their families from 22 rural Midwestern school districts were randomly assigned to the experimental conditions in 1993. Self-report questionnaires were administered at seven time points (pre-test to young adulthood-age 21) to those receiving the Iowa Strengthening Families Program (ISFP) and to the control group. Results showed that growth factors of adolescent internalizing symptoms (grades 6-12) were predicted by ISFP condition and risk status (defined as early substance initiation). Moderation of the condition effect by risk status was found, with higher-risk adolescents benefitting more from the ISFP. Results also supported the hypothesis that the ISFP's effect on internalizing symptoms in young adulthood was mediated through growth factors of adolescents' internalizing symptoms; risk moderation, however, was only marginally significant in young adulthood. The relative reduction rate on clinical or subclinical levels of young adult internalizing symptoms was 28%, indicating that for every 100 young adults displaying clinical or subclinical levels of internalizing symptoms from school districts not offering an intervention, there could be as few as 72 displaying those levels of symptoms in school districts that offered middle school prevention programming. These findings highlight how the positive effects of family-focused universal interventions can extend to non-targeted outcomes and the related potential public-health impact of scaling up these interventions.  相似文献

Research has linked the role of education to delinquency, but much of the focus has been on general population samples and with little attention to demographic differences. Employing a cumulative disadvantage framework that integrates elements of informal social control and labeling theories, this article examines whether academic achievement serves as a positive turning point and re-directs juvenile delinquents away from subsequent offending. Attention is also given to race/sex contingencies. Using a sample of 4,147 delinquents released from Florida correctional institutions (86% male, 57% non-White, average age at release = 16.8 years), propensity score analysis yielded two findings: youth with above average academic achievement while incarcerated were significantly more likely to return to school post-release, and youth with above average attendance in public school were significantly less likely to be re-arrested in the 1-year post-release period. While the academic gains were pronounced among African-American males, the preventive effects of school attendance are similar across race and sex, suggesting that education can be a part of a larger prevention effort that assists juvenile delinquents in successful community re-entry.  相似文献

This article seeks to explain why electoral support for the Venezuelan opposition has increased substantially, using Venezuelan public opinion survey data from LAPOP and an opt‐in sample collected through the online vote advice application Brújula Presidencial Venezuela. It analyzes why Venezuelans who had either voted for Chávez or abstained in 2006 defected and started to support the opposition in subsequent elections. It proposes several reasons: negative voter evaluations of the economy, concern for public safety, and dissatisfaction with Venezuelan democracy. While the finding that negative policy evaluations boost support for the opposition aligns with theoretical expectations, this study finds a strong relationship between having different evaluations of the quality of democracy and supporting Chávez, which shows that the advocacy of two competing visions of democracy by the incumbent and the opposition also affects voting patterns in Venezuela.  相似文献

The positive youth development perspective, a strength-based relational developmental systems model that focuses on mutually influential relationships between individuals and contexts, has been used to study thriving across the second decade of life. However, more attention has been paid empirically to identifying the features of the individual (e.g., intentional self regulation, hope, or purpose) or to enumerating the role of context-general ecological assets than to the nature of individual-context relationships linked to thriving within specific contexts. The goal of this special section is to provide initial research reports about context-specific instances of the thriving process. The research focuses on two contexts where many youth spend a considerable amount, and often the majority, of their time—school and out-of-school time sports activities.  相似文献

Depression is a common and debilitating disorder in adolescence. Sleep disturbances and depression often co-occur with sleep disturbances frequently preceding depression. The current study investigated whether catastrophic worry, a potential cognitive vulnerability, mediates the relationship between adolescent sleep disturbances and depressive symptoms, as well as whether there are gender differences in this relationship. High school students, ages 16–18, n = 1,760, 49 % girls, completed annual health surveys including reports of sleep disturbance, catastrophic worry, and depressive symptoms. Sleep disturbances predicted depressive symptoms 1-year later. Catastrophic worry partially mediated the relationship. Girls reported more sleep disturbances, depressive symptoms, and catastrophic worry relative to boys. The results, however, were similar regardless of gender. Sleep disturbances and catastrophic worry may provide school nurses, psychologists, teachers, and parents with non-gender specific early indicators of risk for depression. Several potentially important practical implications, including suggestions for intervention and prevention programs, are highlighted.  相似文献

ABSTRACT

This paper argues that the divergent performance of the rural economies of China and India after 1950 was a product of the different capabilities of the Chinese and Indian governments to mobilize the labor force and financial resources of the rural population. By mobilizing unpaid labor and the financial resources of the villagers through mediation by the collectives (before 1984) and local administrations (from 1984 to the abolition of agricultural taxation and compulsory rural labor mobilization in 2006), the Chinese state developed rural infrastructure and the quality of the labor force at a pace and geographical scope that was far beyond its limited fiscal capacity. Efforts by the Indian state to establish rural organizations with similar mobilization capabilities failed due to the effective opposition of well-entrenched political and economic interests in the countryside. Unable to mobilize the labor and financial resources of the villagers, the Indian government relied primarily on its limited fiscal resources, which produced a much slower development of physical infrastructure and labor force quality. These are the primary reasons why China’s rural economy developed much more rapidly than India’s, which contributed significantly to the divergence of their national economies in the post-1950 era.  相似文献
