The authors cite clinical literature attesting to the importance of recognizing the family, rather than the individual, as the proper locus of conceptualizing, diagnosing, and treating mental illnesses. Specifically with regard to severe psychiatric illnesses, in particular schizophrenia, family dysfunction contributes to the emergence of the illness, significantly affects its course, and strongly influences the achievement and maintenance of treatment gains. Currently, a movement is afoot to limit sharply the amount and kind of treatment offered to schizophrenic patients and their families. Rooted in a “medical model” or “biogenic” view of the etiology of schizophrenia, this school of thought prescribes psychoeducation as the family treatment of choice. The present article looks at some misconceptions regarding treatment that prompted a widespread turning away from psychoanalytically oriented family psychotherapy for schizophrenic patients and their families, examines the reductionism (biological and behavioral) inhering in the exclusive use of psychoeducation, and looks at the clinical dangers of such reductionism. Finally, it proposes that family psycho-therapists should not abandon a concern with the inner lives of severely ill patients and their families in the face of spuriously generalized claims made by reductionist researchers. 相似文献

The effectiveness of a time-out intervention for adolescent psychiatric patients, adjudicated (delinquent) youth, and behaviorally disordered youngsters was explored in this study. The research was conducted in three psychiatric hospitals for children and adolescents, a facility for adjudicated youth, and in a day-treatment program. Utilizing a comparative outcome model, 813 occurrences of time-out with 274 youth were investigated in order to assess levels of effectiveness. The results indicated that time-out had a significant impact, and the use of a child-care specialist as time-out monitor improves overall effectiveness. Important implications for practicing professionals and clinical researchers are noted. 相似文献

Force variability in isometric responses 总被引:2,自引:0,他引:2

In the present study we examined the contribution of different impulse parameters to peak force variability in an isometric task. Five experiments are reported that each held constant a different impulse parameter while allowing the other impulse parameters to vary. The results indicate that change in force level is the parameter that has the greatest effect on peak force variability, although time to peak force and preload also systematically influence response variability. A formula that accommodates the relation between impulse parameters and force variability is proposed. The data suggest that even in isometric tasks, it is the force-time properties of the impulse, rather than discrete parameters such as peak force, that determine the outcome variability. 相似文献
