An interview measure of social-cognitive skills that have been found to discriminate aggressive and nonaggressive children was developed. The interview was administered to 25 second and third grade children identified by teachers as nonaggressive and 50 second and third grade children identified by teachers as aggressive and referred to an intervention for aggressive children. The interview measure was administered at pretreatment to all children. The interview has adequate inter-rater reliability and discriminates aggressive and nonaggressive children on the following scores: hostile attributions, number of hostile aggressive solutions and number of first solutions that are aggressive, and number of competent solutions in peer entry situations. Furthermore, the SCAP predicts behavioral improvement following a problem solving skills training intervention. (Author)
