The RCADS and RCADS-P are each 47-item questionnaires designed to assess for the same DSM-IV depression and anxiety disorders in children and adolescents. The RCADS and RCADS-P are composed of six subscales: Separation Anxiety Disorder, Social Phobia, Generalized Anxiety Disorder, Obsessive-Compulsive Disorder, Panic Disorder, and Major Depressive Disorder, and also yields an Anxiety Total Score (sum of all five anxiety scales) and Total Score (sum of all six subscales). The RCADS and RCADS-P items were adapted from previous measures as well as evaluation of DSM-IV diagnostic criteria. A majority of items come from the SCAS (Spence 1997 (link)), which itself generated items from a combination of literature review, existing measures, structured interviews, and DSM diagnostic criteria. Additional items on the RCADS and RCADS-P were adapted from questionnaires related to GAD criteria, pathological worry, and depression (Chorpita et al. 1997 (link); Reynolds and Richmond 1978 (link); Kovacs 1981 ). The RCADS and RCADS-P measures ask youths and their parents to rate items according to how often each applies to the child. Responses range from 0–3, corresponding to “never”, “sometimes”, “often”, and “always”. The RCADS has been shown to have good internal consistency, high convergent and discriminant validity, and an adequate factor structure in both community and clinical samples of children and adolescents aged seven to seventeen (Chorpita et al. 2000 (link); Chorpita et al. 2005 (link)). The RCADS-P instructions and items are the same as those of the RCADS, with the wording of RCADS-P item stems modified to suit parent informants (e.g., “I worry about things” modified to “My child worries about things”). The RCADS-P psychometric properties are still under empirical investigation.1
