Using family stress theory, this study examined the relationship between adolescent reports of selected demographic variables (gender, age, family form), interparental conflict (style, content, intensity, resolution), stress due to the pileup of stressors, coping strategies (social support, detrimental coping), and adolescent family life satisfaction. The sample was comprised of 155 adolescents ranging from 14 to 18 years of age who completed self-report questionnaires at one of three rural Oklahoma high schools. Four dimensions of interparental conflict (overt conflict style, conflict about childrearing, conflict about family roles/finances, conflict resolution), stress due to pileup, social support coping, and detrimental coping were significantly related to family life satisfaction. Adolescent age was positively related to family life satisfaction. Within the scope of family stress theory, scholars have addressed how the combination of stressors and coping strategies relates to the adaptation of individuals within family systems (McCubbin and Patterson 1983). Further, investigations of the relationship of parental divorce to well-being in children and adolescents suggest that interaction patterns within various family forms may be more fruitful in explaining the adaptation of youth than parental marital status (Demo 1992). The perception by youth of conflict between their parents (i.e., interparental conflict) has emerged as a key family stressor that has the potential to explain variation in adolescent adaptation in a variety of family forms (Buehler, Krishnakumar, Anthony, Tittsworth, and Stone 1994). Stressor events for adolescents such as interparental conflict generally do not occur in isolation. Rather, they exist within the context of other stressors such as economic stress, difficulties at school, or normative developmental tasks for families with adolescents (e.g., changing family roles to allow greater adolescent autonomy; McCubbin and Patterson 1986). Further, considerable variation exists in the coping strategies (e.g., social support, avoidance) that adolescents use in response to stress (McCubbin and Patterson 1986). Finally, previous research shows variation between certain demographic variables and adolescent adaptation. Thus, the current study was developed to examine how selected demographic variables (gender, age, family form), adolescent perceptions of interparental conflict (style, content, intensity, degree of resolution), stress based on the pileup of stressor events, and coping strategies relate to adolescent satisfaction with family life (one indicator of adaptation).  相似文献

We show that within Bertola and Svensson's second-generation target zone model, mean-reverting interventions and endogenous devaluation risk are closely interrelated. Over the period 1983–93 we analyze the degree of mean reversion in the underlying fundamental process as well as the term structure of interest rate differentials vis-à-vis Germany for six Exchange Rate Mechanism currencies. For Austria, Denmark and the Netherlands, and for Belgium after 1990 our estimates are broadly in line with the first-generation target zone model, whereas those for France and Italy are in accordance with the model that allows for endogenous devaluation risk.

This paper examines generational politics in the Korean American community in Los Angeles. After outlining how the Immigration Act of 1965 led to the acceleration of generational transition in the contemporary immigrant experience, the paper focuses its attention on the entry of the post-immigrant generation into Korean American community politics. Relying on interviews and case studies, the entry of the post-immigrant generation is examined both as a source of new political resources for community mobilization as well as a new source of intra-community conflict. As greater numbers of the post-immigrant generation reach adulthood and become active in political affairs, the issue of generational politics will play an increasingly important role for shaping not only the political developments in immigrant communities but also the broader politics of the American society.  相似文献

To evaluate the effectiveness of couples therapy and determine the characteristics and qualities of couples who fare best in treatment, 139 couples presenting at a nonlaboratory sliding-fee clinic in Dallas, Texas, were evaluated. Observational and self-report measures of the Beavers Systems Model were taken at the first session and, for some subjects, at termination. Therapists also rated the couples on goal attainment and on dimensions of the therapeutic alliance. Not surprisingly, there was a direct association between number of sessions and goal attainment, with couples attending only one or two sessions having the lowest goal attainment. There were also significant family functioning qualities associated with success: more competent couples fared better in therapy. Another consistent finding was that couples with no children did better in treatment than those who were also parents. It is interesting that remarried couples without children did best in treatment, followed by first-married couples with no children, first-married couples with children, and, finally, remarried couples with children. Implications for screening and clinical work with couples are presented.  相似文献

Analyses of data from 600 households in the province of Lubin, Poland, five years after the economic transformation indicated the transfers of goods and services between households to be quite prevalent, with households with high levels of resources giving goods and services and those with low levels of resources receiving goods and services. The receipt of such transfers does not improve the living conditions of the receiving households relative to those who do not receive help; in fact, those receiving help report lower levels of satisfaction than those not receiving assistance.  相似文献

Support to frail elders is of international and growing importance. This article compared receipt of assistance with ADL limitations, home health help, any assistance received, and unmet needs in functionally impaired individuals aged 70 years old or older in the United States (n = 1847, 80% women, M age = 80 years) and Great Britain (n = 1203, 57% women, M age = 78 years). Informal and formal assistance levels were higher in Great Britain, and rates of unmet need did not differ across ADL domains measured. Receipt of formal and informal care were associated positively, which is consistent with both supplementary and complementary perspectives on the formal-informal care interface. Few individuals in either country received formal services alone. Results suggest that community-based formal support does not substitute for family help. Implications for family and economic policy are discussed.  相似文献

While two-stage designs in problem gambling research are expensive and relatively difficult to execute, they have the potential to yield more accurate prevalence estimates as well as valuable additional information about gambling and problem gambling in the community. However, gains in precision are heavily dependent on the accuracy of the screening methods used and the sample sizes involved. Sound practice requires reliable information about the variances and confidence levels associated with different screens. In the spirit of contributing to the ongoing dialog about ways to improve the measurement of problem gambling, we examine several reasons to question whether the revised estimates offered by Gambino are in fact an improvement.  相似文献
