The transition to parenthood: I. The rating of prenatal marital competence   总被引:1,自引:0,他引:1  
J M Lewis 《Family process》1988,27(2):149-165
This article is the first of three that will present data from the Timberlawn Psychiatric Research Foundation Young Family Project, a study of the development over time of competent family systems. The Project is briefly described and findings are presented from the initial data collection period. The operational definitions of marital competence and the Continuum of Marital Competence are presented, and the data are interpreted to suggest that the spouses' levels of individual psychological health, their agreement on values, and their socioeconomic status are related to the level of marital competence. The level of prenatal marital competence at Time 1 is used as an independent variable with which to predict both changes in marital structure and incorporation of the child into the family system at 3 months and 1 year postpartum. The results of these analyses will be presented in two subsequent articles.  相似文献

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

Through school-sponsored health fairs, 398 adolescents (153 males and 245 females) between the ages of 14 and 18 completed a questionnaire on their compliance with six of the U.S. Dietary Guidelines. Results indicated that adolescents report highest compliance on "eat a variety of foods" and "eat foods with adequate starch and fiber." Conversely, they indicated low compliance on "reduce sugar intake" and "reduce fat, saturated fat and cholesterol intake." Sex differences were noted on two dietary guidelines. Females reported lower compliance with respect to "maintain desirable body weight." Males, on the other hand, reported lower compliance than females on "reduce salt intake." Given the fact that the dietary guidelines of "reduce fat, saturated fat and cholesterol," "maintain desirable body weight," and "reduce salt intake" are all aimed at reducing cardiovascular risk, the low compliance reported by adolescents may have long-range health implications.  相似文献

This article examines the question of how the lack of differences in general self-esteem between adolescents of ethnic minorities and Dutch adolescents can be explained. Attention is focused on the reflected appraisal process. It was found that for adolescents of ethnic minorities there is a significant relationship between general self-esteem and the perceived evaluation of family members, and no such relationship with nonfamily members. For the Dutch adolescents the findings are the opposite, which may explain why adolescents of ethnic minorities in general do not have lower general self-esteem, despite low status, prejudice, and discrimination.  相似文献
