The Guide to the Assessment of Test Session Behavior: Validity in Relation to Cognitive Testing and Parent-Reported Behavior Problems in a Clinical Sample

Examined the validity of the Guide to the Assessment of Test Session behavior (GATSB) in a clinical sample. The GATSB is a structured and standardized measure that was normed on the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) standardization sample. The purpose of this study was to extend validity research on the GATSB to cognitive measures other than the WISC-III and to parent-reported child behavior problems. Test observations were taken for 122 children ages 6 to 16 years who were referred to an outpatient psychology clinic for psychoeducational evaluations. GATSB scores demonstrated a moderate relation with general indexes from the WISC-III, the Woodcock-Johnson Psychoeducational Battery-Revised (WJ-R), and the Wide Range Assessment of Memory and Learning (WRAML), but displayed low magnitude correlations with the Child Behavior Checklist (CBCL). These results expand existing data supporting the validity of the GATSB and suggest that it may be fruitfully adopted into a clinic setting.
