A modified version of the Adolescent Problem Inventory (API) for boys and the parallel Problem Inventory for Adolescent Girls (Freedman, Rosenthal, Donahoe, Schlundt, & McFall, 1978; Gaffney & McFall, 1981) was used to assess adolescents' social skill in handling deviance. Adolescents self-reported their most likely responses to a series of problematic hypothetical situations, which were then rated for their competence not only in resolving the situation at hand but also in making future problematic situations less likely using a 0 to 10 scale. Situations included conflicts with peers, parents, and teachers, and situations in which adolescents might be tempted to engage in delinquent behaviors.
