Use of the Child and Adolescent Functional Assessment Scale to predict service utilization and cost.

The Child and Adolescent Functional Assessment Scale (CAFAS) is a multidimensional measure of impairment that assesses the extent of interference in day-to-day functioning secondary to emotional, behavioral, or substance use problems. Respondents were 984 youths, aged 5 to 17, who were referred for mental health services. They were assessed at intake and at 6 and 12 months postintake with a battery of measures administered by evaluation staff who were independent of treatment. Utilization indicators included restrictiveness of care, total cost, number of bed days, and total number of days of service received. The CAFAS total score at intake was a significant predictor of service utilization and cost determined at 6 and 12 months postintake. The CAFAS score was also the best predictor when compared with other measures of psychopathology. Only the CAFAS and presence of conduct disorder contributed to the prediction of service utilization and cost at 12 months.
