This study examined the costs of pervasive developmental disorder (PDD) treatment in a large healthcare organization. When compared to individual therapy and mixed therapy, family therapy had significantly fewer sessions, fewer episodes of care, and better cost-effectiveness. Individual therapy had significantly shorter treatment length than mixed therapy. There were no differences in treatment length or number of episodes by license, but dropout and cost-effectiveness were significantly different. Medical doctors had the highest dropout and best cost-effectiveness, while Marriage and Family Therapists had the lowest dropout and Masters of Social Work had the poorest cost-effectiveness. Children had significantly higher dropout than other age groups. An autism diagnosis was associated with fewer sessions but additional episodes of care when compared to PDD. Having a comorbid diagnosis is associated with longer treatment length but slightly fewer episodes of care. A regression model to predict number of episodes of care by intensity of treatment, provider type, and modality, intensity of treatment explained only 6% of the variance.
