The purpose of this study is to compare the drug abusing adolescent, along with his family, with a non-drug abusing adolescent and his family by (l) a comparison of the adolescents on measures of self esteem and perceived parental behavior, (2) a comparison of the parents of drug abusing adolescents with the parents of non-drug abusing adolescents on child-rearing attitudes and on distortion in perceived parental behavior, and (3) an identification of the salient factors contributing to the prediction of drug-using behavior in adolescents. The adolescent's self esteem, his perception of parental behavior, the ability of the parents to predict the child's parental perceptions, and the professed parental attitudes toward confidence and responsibility in child-rearing, all combine to suggest a set of factors differentiating the drug abusing adolescent from the non-drug abusing adolescent.
