Predictors of persistence in a longitudinal preventive intervention program for young disruptive boys.

Several investigators have underlined the importance of long-term prevention programs in order to expect positive results for at-risk children. One essential prerequisite to addressing this issue is the retention of participants in such programs. The present study aims at examining the contribution of mother-child interactions, mother's social isolation, improvement in the mother-child relationship, and improvement in the child's behavior to the prediction of persistence. Participants (n = 59 disruptive boys) were recruited for a 3-year multicomponent preventive intervention program. Results indicated an improvement of the boys' behavior (reduction of inattention/hyperactivity and reduction of fighting) during the first year of the program, and showed that mother-child positive interactions before the beginning of the program were the best predictors of persistence. Implications of these results for long-term preventive programs are discussed.
