Conducted a 10-wk self-esteem workshop for 15 male inmates (most were aged 19-25 yrs) serving 2.5-5 yr sentences for drug-related offenses, burglary, aggressive offenses, and murder. A pre- and postworkshop measure of self-esteem was administered. The program emphasized family-related self-concept, using experiential and discussion strategies. Topics included family antecedents of self-perception, self-assessment and acceptance, behavioral demonstration of self-worth, and current family interactions and effects. Results show a significant increase in Ss' family-based self-esteem scores, but no change in peer- or work-oriented self-concept. The fact that family-related self-concept appears to be amenable to improvement in the prison setting should have implications for rehabilitation goals and subsequent program planning.
