The purpose of the present archival study was to investigate the relationship between parental substance abuse and the risk for maladjustment and psychopathology in children in a clinic sample. Children of alcoholic parents and children of drug-dependent parents were compared to children of non-substance abusing parents. The subjects were 83 boys age 6 to 12. Children of substance abuse parents had lower levels of adaptive functioning and higher levels of school behavioral problems. Although previous studies have reported a strong association between an adverse family environment and the risk of child maladjustment, the present study did not find that the addition of an adverse family environment increased the risk for maladjustment or school behavioral problems in children of substance abusers.
