Conduct Disorder Rating Scale- for parents (CDRS-P)


It is considered a public health priority to effectively manage the troublesome behaviour of disorderly adolescents and children. Conduct disorder (CD) is estimated to affect up to 5% of children between the ages of four and sixteen and is often linked to drug abuse, violence, and sexual victimization. Therefore it is important to have reliable and consistent measures of CD. However, many existing scales measure CD is ways which are not wholly consistent with the criteria set out in the DSM-IV. To address this shortcoming Waschbusch & Elgar (2007) developed the Conduct Disorder Rating Scale- for parents (CDRS-P).


The psychometric properties of the Conduct Disorder Rating Scale- for parents (CDRS-P) are discussed in Waschbusch & Elgar, (2007).
