S. Johnson et al., The Diagnostic Interview Schedule for Children, Adolescents, and Parents: Initial reliability and validity data, BEHAV CHANG, 16(3), 1999, pp. 155-164
This study evaluated the psychometric properties of the Diagnostic Intervie
w Schedule for Children, Adolescents and Parents (DISCAP; Holland & Dadds,
1995), for DSM-IV anxiety disorders in children and adolescents. Two studie
s were conducted to examine the reliability and validity of the DISCAP. In
the first study, the DISCAP and the Youth Self Report (YSR; Achenbach, 1991
c) were administered to 120 nonclinical adolescents aged 12 through to 14 y
ears. In the second study, the DISCAP and Child Behaviour Checklist (CBCL;
Achenbach, 1991b) were administered to parents of 57 clinical children and
adolescents aged 6 through to 16 years. Inter-rater reliability data was co
llected, and both concurrent and discriminant validity of the DISCAP were a
ssessed against the YSR and CBCL. Inter-rater agreements for primary diagno
ses were high, and rating scale data supported the concurrent and discrimin
ant validity of the DISCAP diagnoses. Results suggest that the DISCAP can b
e used to facilitate reliable and valid diagnoses of childhood anxiety diso
rders.
