The relationship between basic research, theory, and clinical work with families is conceptualized during a discussion of Jamaican family structure and the application of change theory to a clinical case of depression in a Jamaican woman. It was found that three types of family structure are prevalent in Jamaica. The European ideal of a patriarchal-patrifocal structure creates problems for working-class Jamaicans. General system theory provides support for a different model. Change theory is applied to resolve the paradox created by the European model. 相似文献

A critical review of the theoretical and outcome studies on family therapy with delinquents is presented. Assessment of the theoretical developments reveals that families of delinquents may be distinguishable from other families by their interactional sequences and processes. The available outcome studies within the field indicate that family therapy is viable for interventions with this population, with behavioral, structural, strategic, and communication approaches receiving the most support, but more specific and robust evidence is still needed. Trends in the research and critical issues are identified and used to provide suggestions for future research and practice. 相似文献

Interventions were employed to program maintenance following correspondence training. The use of reinforcement of verbalization and a mixed sequence of procedures designed to establish indiscriminable contingencies was evaluated in multiple-baseline designs across subjects and behaviors. The results indicated that target behaviors were maintained under less intrusive interventions and in the absence of programmed contingencies during extended follow-up conditions. The results are discussed in terms of changes in reinforcement schedules established in maintenance interventions. 相似文献

Two studies were conducted to investigate the effects of perceived control in two men's prisons, one housing 181 inmates and the other housing 623 inmates. In both prisons, inmates' perceived control over the environment was found to be significantly related to their ratings of their living accommodations, experienced stress, and physical symptoms, even when type of cell was held constant. 相似文献
