Although the relation between family relationships and the timing of sexual debut has been the focus of many studies, research
on mediating factors is scarce. This study examines whether low levels of family cohesion result in an earlier onset of romantic
and sexual experiences, and whether the link between family cohesion and an early sexual debut is mediated by early romantic
initiation. A longitudinal sample of 314 adolescent girls and 222 boys, aged 12–17 at Wave 1, completed questionnaires at
three measurement points with three year intervals. The results showed that sexual debut followed romantic initiation for
77% of the participants. For early adolescent females (aged 12–14), high levels of family cohesion resulted in a later sexual
debut and this association was fully mediated by a delay of romantic initiation. Among boys and older girls, timing of romantic
initiation did not mediate the link between family cohesion and timing of sexual initiation. Early adolescent girls who have
negative relationships with their parents turn to romantic relationships for intimacy and support, which subsequently provide
the opportunity for an early sexual debut. Low levels of family cohesion thus primarily precipitate romantic initiation and
sexual initiation appears to be secondary to this process among girls in this age group. 相似文献

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

Evidence suggests that lesbian and gay young adults use substances more frequently than their heterosexual peers. Based on
the life course perspective, we argue that this difference may be due to the unavailability of marriage as a turning point
in the lives of lesbian/gay young adults. We use data from a nationally representative sample of youth (N = 13,581, 52.4% female, 68.6% white, ages 18—26) to examine sexual orientation differences in substance use and explore whether
these differences vary by romantic partnership formation in young adulthood. We find that the formation of more serious partnerships
(e.g., cohabitation, marriage) is associated with less frequent substance use among heterosexual young adults, though this
pattern does not hold for lesbian and gay young adults. We conclude that the partnership options available to lesbians and
gay men do not provide the same health-protective benefits that marriage does for heterosexuals. 相似文献

正第三章五年计划下的经济发展与经济政策①第一节苏维埃经济彻底社会主义化的历程起初,国外并没有把五年计划当回事,仅将其当作一种宣传,意在激励人们工作。这种怀疑论走得太远了;当计划的内容在苏维埃俄国大多得以落实时,怀疑让位于震惊,在某些圈子里,及至痴迷。然而,彻底的怀疑与过度的痴迷一样,都是非理性的。但是,怀疑论者有一点是对的:一眼就能看出,计划的巨额投资并没有带来一般生活水准的同步改善。同时,不要忘记,掌控所有资源、以 相似文献

My brand new bicycle had been stolen! Disbelief. Anger! Disappointment... I had been riding it for only a day,and was as excited as a,well,a boy with a new bike. Even though I only paid what would be the equivalent of half a tank of gas for my truck back home,I was still sorely put out. 相似文献

亚太地区出现一个全新的局面。一方面,区域内的国际合作正在拓展,一个能够带来区域稳定和安全并得到普遍认同的体系正在形成。另一方面,亚太国家之间争夺地区内影响力的对抗和竞争的危险性日益加重,甚至有可能导致公开冲突并阻碍区域一体化的进程。为此,继续构建一个囊括地区内所有国家的,以合作、互信、对等安全为基础的新机制十分重要。亚太地区的发展直接影响俄罗斯联邦的利益,俄罗斯倡导要确保地区的稳定和安全,以及囊括所有亚太国家的建设性合作。近年来,俄罗斯政府特别重视促进东西伯利亚及远东地区的经济发展,该地区是俄罗斯实现亚太地区一体化的一个重要载体。开展同中国的合作,进一步开发俄罗斯远东地区,对于俄罗斯贯彻经济战略、实现经济现代化、融入亚太地区的经济空间,都具有原则性的重要意义。 相似文献
