Despite the clinical relevance of self-injurious thoughts and behaviors (SITB) among youth, little is known about the subset of youth most at-risk for SITB. This study examined the moderating roles of gender, racial/ethnic background, and school-level (and their interactions) on rates of SITB within a large (N = 2638, 52.2% female), ethnically-diverse sample of middle- and high-school youth in a relatively poor and underserved area of the Southern United States. Extending extant research in this area, findings indicated a significant interaction between gender and race for self-injurious behaviors, with African–American boys reporting higher rates than all other groups. Findings also indicated significant interactions between school-level and both gender and race for self-injurious thoughts. Whereas comparable levels of self-injurious thoughts were reported across middle- and high-schools for girls and African–American youth, the frequency of these thoughts was higher among both boys and White students in high-school (vs. middle-school). Results highlight the need for further research on SITB among diverse youth in underserved areas.  相似文献

Depressive symptoms in Latino youth have been related to both culturally-universal and culturally-based stressors. However, few studies have examined the unique contributions of culturally-based stressors above and beyond other types of stressors. Moreover, no past studies with Latinos have examined the role of culturally-based stressors within a hopelessness model of depressive symptoms, a cognitive model with the strongest empirical support in adolescence. The current study examined these issues in a sample of 171 Latino adolescents (7th-10th grades; mean age?=?14; 46?% male). The Latino adolescents were primarily Mexican-American (78?%) and born in the United States (60?%). Students completed measures during a school period on their experiences of parent-child conflict, economic stress, discrimination from peers, and acculturative stress as well as depressive symptoms and attributional style. The results indicated that culturally-based stressors (e.g., acculturative stress and discrimination) predicted greater depressive symptoms even when controlling for culturally-universal stressors (e.g., parent-child conflict, economic stress). Moreover, a negative attributional style moderated the relationship between culturally-universal stressors and depressive symptoms, but this was not the case for culturally-based stressors. Culturally-based stressors play an important role in depressive symptoms among Latino youth. These stressors predicted greater symptomatology even when controlling for other types of stressors and a negative attributional style. These findings suggest that there may be other cognitive risk factors associated with culturally-based stressors.  相似文献

Socioeconomic stress has long been found to place youth at risk, with low family income conferring disadvantages in adolescents’ school achievement and success. This study investigates the role of socioeconomic stress on academic adjustment, and pinpoints family obligation as a possible buffer of negative associations. We examined direct and interactive effects at two time points in the same sample of Asian American adolescents—early high school (N = 180 9th–10th graders; 60 % female) and 2 years later in late high school (N = 156 11th–12th graders; 87 % of original sample). Results suggest that socioeconomic stress is indeed associated with poor academic adjustment, measured broadly through self-reported GPA, importance of academic success, and educational aspirations and expectations. Family obligation was positively related to adjustment, and also was found to buffer the negative effects of socioeconomic stress, but only during adolescents’ later high school years. Adolescents reporting more family obligation experienced less of the negative effects of financial stress on academic outcomes than those reporting lower obligation. Cultural and developmental implications are discussed in light of these direct and moderating effects.  相似文献

While organizational systems are associated with innovation and adaptability, interorganizational relationships may be predisposed to stability. Using multinomial logit analysis, we test how resource dependencies affect system stability in local United Way (UW) systems between 2000 and 2010. We find strong support for the resource dependence argument. UW are less likely to drop larger, powerful partners that are strong fundraising partners. However, powerful, long-term partners not contributing to the strategic objectives of the UW system are more likely to experience a decrease in allocations. While powerful resource partners may capture the UW, UW systems continue to change through the addition of new partners and the reallocation of resources among long-term partners. However, context also affects the capacity for change. Larger UWs are more likely to add new partners and less likely to keep long-term partners.  相似文献

The study examines separation-individuation during adolescence and young adulthood for gay, lesbian, and bisexual youths, and evaluates the consequences of parent-youth relationships for well-being and sexual orientation identity development. Seventy-two youths completed interview and questionnaire measures of relatedness, autonomy, and conflictual independence in relation to mothers and fathers, along with self-reports of parent attitudes, identity consolidation, and well-being. When youths perceived that their parents had relatively accepting attitudes regarding sexual orientation they demonstrated closer relatedness and greater conflictual independence with parents, but not greater autonomy. Both accepting parental attitudes and greater separation-individuation predicted more positive well-being for the youths, though only parental attitudes predicted greater consolidation of sexual orientation identity. Although mothers were generally closer and more supportive than fathers, relationships with both parents were important, independent predictors of personal adjustment. The discussion proposes mutual influences among separation-individuation, perceived acceptance by parents, identity consolidation and well-being.  相似文献
