The Ohio scales youth form: Expansion and validation of a self-report outcome measure for young children

We examined the validity and reliability of a self-report outcome measure for children between the ages of 8 and 11. The Ohio Scales Problem Severity scale is a brief, practical outcome measure available in three parallel forms: Parent, Youth, and Agency Worker. The Youth Self-Report form is currently validated for children ages 12 and older. The Ohio Scales Problem Severity scale was administered to a clinical and comparison sample of children, ages 8-11, then readministered 1 week later to a subsample of children in order to examine test-retest reliability. The Ohio Scales demonstrated acceptable internal consistency and reliability. The Ohio Scales was significantly correlated with the Behavior Assessment System for Children (BASC) across both samples, providing evidence for concurrent validity. Children of the clinical sample reporting higher scores (i.e., more symptomatic) than the children of the comparison sample on the Ohio Scales, thereby demonstrating construct validity.
