Correspondence between parents' reports on the Behavior Problem Checklist.

Interparent agreement on the Behavior Problem Checklist (BPC) was assessed in relation to several potentially influential variables. Major findings indicated parent agreement to be of a moderate level, generally higher in nondistressed than distressed samples, lower on Personality Problem items than Conduct Problem items, very low regarding presence of specific behaviors, and importantly related to type of reliability index employed. Issues deserving additional research effort are discussed.
