Fifteen participants in the study attended seven group-sessions covering risk education, training in self-management skills, assertiveness training, and social and lifestyle issues. In addition, participants provided information for pre- and post intervention assessments covering AIDS risk knowledge, on sexual practices over 4-month retrospective periods, and on self-monitoring records of ongoing sexual activities and participation in role plays assessing behavioral assertiveness skills for resisting high-risk coercions. An 8-month follow up was conducted. Following intervention, the participants reported substantial changes, including high proportion of condom use; a marked decrease in risky activities with multiple partners; and maintenance of change at follow-up. These results indicate the usefulness of this group intervention model for counseling persons in risk-behavior reduction. 1 table, 2 figures, and 18 references (Author abstract modified)
