The development of a child assessment interview for research and clinical use

Abstract

The Child Assessment Schedule (CAS) was developed to address the need for a standardized child interview that could be used for research and clinical purposes. The CAS has several distinguishing characteristics: (1) Questions and responses are standardized, (2) the format was designed to enhance rapport with the child, and (3) information necessary for DSM III childhood diagnoses is explicitly solicited. The CAS was administered to 32 child outpatients, 18 inpatients, and 37 normal controls. Derived scores were obtained for total psychopathology, 11 content areas, and 9 symptom complexes. Interrater reliability for the total CAS score was quite high. The CAS was able to discriminate among the three groups in total score indicating degree of psychopathology, on 9 of the 11 content areas, and on 8 of the 9 symptom complexes. Significant correlations were found between the CAS and maternal report of child behavior and between the CAS and child self-report of internal affects. It was concluded that the CAS has adequate reliability and validity, although further research is indicated.
