Abstract
The importance of adequately measuring independent as well as dependent variables in studies evaluating therapeutic services provided to antisocial children is indicated. Data were obtained from a study in which 139 antisocial children were stratified according to age and then randomly placed into 14 groups. The children were randomly assigned to either of 2 treatment strategies or to a control treatment strategy. The effect of the treatments was evaluated by 2 pre-post selfrating scales, by a prepost inventory completed by therapists, and by behavioral observations of both children and their therapists. Measurements of the children's and therapists' behaviors were secured at each weekly 2-hr, meeting for approximately 30 weeks. Very few significant differences occurred between the treatment and control groups on the dependent variables. The findings indicated that independent checks are necessary to insure that therapeutic strategies are actually being implemented, thus providing for an adequate test of their effects on the dependent variables.
