Interview skills deficits may limit employment prospects of mentally retarded adults. Although numerous papers highlight the importance of interview skills, few have validated effective strategies for use with mentally retarded persons. Further, there has been a lack of research contrasting rival interview skills training strategies. The present study was conducted with two mentally retarded young adults. It contrasted peer-directed instruction, in which both participants were equally deficient in the target skills, with teacher-directed instruction. Results of the investigation indicated that instruction, rehearsal, and feedback may be effective strategies regardless of who provides instruction. Comparisons of teacher-directed and peer-directed instruction indicated little or no difference in the effectiveness of the two procedures. However, the peer-directed procedure involved considerably less staff time than did the teacher-directed procedure.  相似文献

J M Lewis 《Family process》1988,27(3):273-283
At 1 year postpartum, 22 of 38 couples demonstrated the same level of marital competence as they had prenatally, 14 couples demonstrated deterioration in their marital relationship, and 2 couples were improved. At each of four levels of marital competence, there was a trend for the couples to demonstrate the same relationship response to parenthood. Highly competent relationships remained at high levels of competence. Competent but pained relationships were most vulnerable to regressive change in structure. Dominant-submissive, complementary relationships tended to remain stable at that level. Dominant-submissive, conflicted or severely conflicted relationships were most unpredictable and stability, regression, and improvement were seen. These findings are explored for possible correlations and are discussed from the perspective of several current models of family development.  相似文献

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
