Parents or parent surrogates of a sample of 18 juvenile clients were interviewed by telephone using a semistructured questionnaire to measure perceived changes in behaviors and attitudes following participation in a community-based JDPP. Consistent with the theoretical framework of the social development model, Hirschi's four social bonds (attachment, commitment, involvement, and belief) were used as criterion variables. The community-based JDPP served as the independent variable. Improved school achievement was reported by 77.8 percent of parents after participation in JDPP; 72.2 percent of parents noted an increase in children's interest in school. Several other areas were also perceived as considerably improved: willingness to help at home, time spent doing homework, hopefulness about the future, communication ability, and amount of time spent talking with parents. Overall, the study indicated that parents perceive significant changes in the behavior and attitudes of children after participation in a community- based JDPP.
