The present study demonstrates the safety and effectiveness of an outpatient program designed to respond to adolescent-precipitated crises by mobilizing and restructuring the family's kinship system. Families of 75 adolescents at risk for hospitalization were followed up to 24 months after treatment with Systemic Crisis Intervention. Measures of offspring and family functioning, suicidal behavior, institutional use, and treatment costs are presented. Results clearly demonstrate the safety, effectiveness, and economic viability of Systemic Crisis Intervention.  相似文献

Therapists have a mandate to bring about change, and family therapists appear to have unusual leverage to fullfill such a mandate, that is, to facilitate changes rapidly and effectively. Because and in spite of this mandate, the very notion of change deserves critical reflection. The history of ideas and our clinical experience teach us that changes may be problematic. They may come too fast or too slowly, may endure or fade away, may turn out to be desirable or undesirable, equitable or inequitable, and may, when further consequences and larger systems levels are taken into account, be beneficial or disastrous. This essay examines some of the problematical and contradictory aspects of change and delineates two perspectives on change--systemic optimism and systemic pessimism.  相似文献

The child-rearing beliefs of 32 mothers and 36 day-care providers in Mexico were compared. Day-care providers expected children to master developmental skills at an earlier age than did mothers. Day-care providers more strongly valued the development of independent and cooperative behavior, and placed less importance on obedience. They also reported employing more flexible and nonauthoritarian discipline strategies than did mothers. Mothers and caregivers did not differ in the extent to which they attributed the success of their discipline strategies to their own actions rather than to external factors. Also examined was how mothers' beliefs differed in families characterized by interdependent versus individualistic social structures. In interdependent families, mothers were more likely to believe in later mastery of developmental skills and to make external attributions. These findings suggest that Mexican children experience incongruous social norms as they move between home and day care settings, and that these norms, at least within the home, are associated with the social structural features of the setting.  相似文献
