The purpose of this study was to compare the interactions of clinic-referred mothers and fathers with their conduct problem children with those of nonclinic “normal” parents and their children without problems in terms of their expression of positive and negative affect. Forty parents and their 20 children participated. Results indicated that clinic mothers and fathers exhibited significantly increased negative verbal behaviors with their children than nonclinic parents. Valence scores also indicated clinic mothers had significantly more negative nonverbal affect behaviors than nonclinic mothers. Clinic children exhibited significantly less positive verbal and nonverbal affect behaviors with their mothers than nonclinic children. Valence scores indicated that clinic children exhibited more negative nonverbal behaviors with both mothers and fathers in comparison to nonclinic children.
