ADAD can be used to assess substance use and other life problems, to assist with treatment planning, and to assess changes in life problem areas and severity over time.ADAD produces a comprehensive evaluation of the client and provides a 10-point severity rating for each of nine life problem areas. Composite scores to measure client behavioral change in each problem area during and after treatment can be calculated. Only 83 items of the 150 ADAD items are used for measuring change: posttest, followup tracking in an evaluation of clients after treatment, and evaluation of treatment outcome. These 83 items are circled on the ADAD form.Although ADAD was originally developed for use with adolescents in substance use disorder treatment settings, it has proved useful as a general assessment tool for adolescents in school settings, youth social service agencies, mental health facilities, and facilities and programs within the criminal justice system
