Further, Harrell and Wirtz (1989) assessed the utility of the ADI by comparing ADI results from a sample of 264 adolescents to ratings from clinicians with training in adolescent assessment across the

four domains (e.g., loss of control, social and interpersonal, psycholog- ical, and physical indicators) of the ADI. Correlations on each of the four

domains were between .75 and .79 (p b .0001), and all the domains showed significant positive correlations with the clinician severity rating, which ranged between .64 and .71 (p b .0001).
