Tobacco, alcohol, and drug use are problems for American-Indian people. We reviewed these problems and the explanations for them and described a bicultural competence skills approach for preventing substance abuse with American-Indian adolescents. Data from a study of that approach suggest its efficacy with American-Indian youth. At posttest and a 6-month follow-up, American-Indian subjects who received preventive intervention based on bicultural competence skills concepts improved more than did American-Indian subjects in a no-intervention control condition on measures of substance-use knowledge, attitudes, and interactive skills, and on self-reported rates of tobacco, alcohol, and drug use. Our findings have implications for future substance-abuse prevention research with American-Indian people.  相似文献

Training in systemic therapy necessitates a structured approach to teaching systemic thinking. The Systemic Therapy Sessions Summary Form, a record-keeping method, is presented as a tool for enhancing training in systemic therapy. The purpose of this form is to provide the structure for the trainee to develop circular hypotheses, to connect reflexively the assessment and intervention components of therapy, and to maintain a sense of the evolving nature of therapy across sessions. A case example illustrates the use of this record-keeping format.  相似文献

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

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
