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

The belief that individual marital therapy (IMT) is an ineffective form of treatment for marriage problems and markedly inferior to the conjoint approaches has become almost an article of faith in family therapy circles. This position was originally advanced in the influential reviews of the research literature conducted by Gurman and Kniskern, and their conclusions have been cited in numerous other articles. This paper re-reviews the research studies purportedly supporting this conclusion and finds almost all of them to be invalidated by gross flaws in design and implementation. It is argued that from the highly inadequate evidence available, no conclusions can be reached concerning either the absolute or relative effectiveness of IMT. 相似文献

The analysis of behavior sequences can be a useful technique for understanding family process and has been increasingly employed as a result of developments in family theory. Some of the most popular sequential analytic methods are reviewed, and problems of applying these methodologies to investigations of family interaction are discussed. Independence-of-observations, nonstationarity, and autocontingency are differentiated as three distinct types of serial dependence. In addition, issues concerning the choice of data type, analysis of low base rate behaviors, and the decision as to whether to correct for base rates are considered. Guidelines are presented for dealing with each of these issues in the context of the research or clinical question being addressed. 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
