The purpose of this study was to evaluate the reliability and validity of the Korean version of Maternal Behavior Rating Scale(MBRS) and Child Behavior Rating Scale(CBRS) by Mahoney(1999). The subjects of this study consisted of 30 parent-child dyad(17 normal children and 13 developmental disordered). Data were collected by videotapeing the mother and child while playing together at home. Two raters scored independently mother and child interaction by each of the items of MBRS & CBRS on a 5-point Likert scale. The results were as follows. First, MBRS and CBRS had sufficient internal reliability. Second, factor analytic study of MBRS and CBRS indicated that two factor model accounted best for the data. Third, while interacting with children, mother of normal children were more responsive than mother of developmental disordered children. And normal children were more active than developmental disordered children. This results supported reliability, validity and clinical utility of MBRS and CBRS.
