Existing research suggests that sexual minority youth experience lower levels of well-being, in part because they perceive less social support than heterosexual youth. Sexual minority youth with strong family relationships may demonstrate resilience and increased well-being; however, it is also possible that the experience of sexual stigma may make these relationships less protective for sexual minority youth. Using two waves of data from the National Longitudinal Study of Adolescent Health, we explore the links between same-sex attraction, family relationships, and adolescent well-being in a sample of over 13,000 7th–12th grade adolescents (51 % female, 52 % non-Latino/a white, 17 % Latino, 21 % African American, and 7 % Asian). Specifically, we examine whether lower levels of parental closeness, parental involvement, and family support among same-sex attracted youth explain in part why these youth experience increased depressive symptoms and risk behaviors, including binge drinking, illegal drug use, and running away from home, relative to other-sex attracted youth. Second, we ask whether family relationships are equally protective against depressive symptoms and risk behaviors for same-sex attracted and other-sex attracted youth. We find that same-sex attracted youth, particularly girls, report higher levels of depressive symptoms, binge drinking, and drug use in part because they perceive less closeness with parents and less support from their families. Results also suggest that parental closeness and parental involvement may be less protective against risk behaviors for same-sex attracted boys than for their other-sex attracted peers. Findings thus suggest that interventions targeting the families of sexual minority youth should educate parents about the potentially negative effects of heteronormative assumptions and attitudes on positive adolescent development. 相似文献

This article explores three formats for interstate relations developed by, or at least significantly influenced by Germany in the post-Cold War period: the Petersburg Dialogue, the German–Russian–Polish Trialogue and the Weimar Triangle. An examination of the form and function of each of these formats is followed by a discussion of what these formats have in common and why they are worthy of further study. The paper addresses whether this ‘variable geometry’ of Germany's foreign policy of trust-building is likely to survive a period of turbulent relations or changes in leadership and, furthermore, how the effectiveness of dialogues, trialogues and triangles might be evaluated. 相似文献

Parental reports of adolescent substance use were compared to the adolescents' self-reports using identical scales. Congruence was defined as exact agreement on whether adolescents were current users, ex-users, or never-users. Both parents were found to be less accurate in predicting their adolescents' alcohol use compared to cigarette or marijuana use. Single mothers were significantly less likely to be congruent than were mothers from two-parent households. Mother and father congruence on all substances was unrelated to the adolescent's sex, race, or after school employment. For both parents, congruence for adolescent marijuana use was significantly related to the age and GPA of the adolescent. Congruence may also reflect important properties of family functioning, as significant relations were found between both adolescent and parent ratings of family cohesion and parent-adolescent congruence on perceptions of marijuana use.This research was supported by Grant DA03706 from the National Institute of Drug Abuse (Hyman Hops, Principal Investigator).Jennifer Langhinrichsen is a doctoral candidate in psychology interested in adolescent and family interactions. The other authors are psychologists or data analysts working on family influences on substance use and mental health. 相似文献

Based on 10 weekly telephone interviews with first-year college students (N=202; 63% women; M=18.8 years, SD=.4), within- and between-person associations of positive and negative affect with alcohol use were examined. Multi-level models confirmed hypothesized within-person associations between weekly positive affect and alcohol use: Higher positive affect weeks had greater alcohol consumption, more drinking and heavy drinking days in the same week, and less plans to drink the following week. However, between-person, average positive affect did not predict individual differences in alcohol use. The negative affect—alcohol use association was complex: Within-person, higher negative affect was associated with less drinking days but between-person, with more drinking days; lability in negative affect was associated with greater average alcohol use and more drinking and heavy drinking days. Health promotion efforts for late adolescent and emerging adult students are advised to recognize these paradoxical effects (e.g., promoting dry celebratory campus-events, strategies to manage negative mood swings).

Alexis de Tocqueville believed that “democratic peoples’... passion for equality is ardent, insatiable, eternal, and invincible.”
This article examines whether and under what conditions residents of the United States demonstrate such a commitment to equality.
I show that at many points in history, Americans have indeed chosen to move toward greater justice and less oppression; however,
there are clear limits to their passion for equality. White Americans endorse less social, political, and economic equality
than do African Americans, but even the latter often resist equality for groups that they perceive to be threats, or for behaviors
that threaten strong social or moral norms. The article discusses implications for political activists of these patterns of
support for and resistance to greater equality, and suggests strategies for overcoming oppression and promoting justice. 相似文献
