This paper summarizes the process of instituting a standardized mental health assessment protocol in a community health treatment program serving maltreated youth. The assessment program was intended to: (1) provide descriptive data regarding the populating utilizing the service; (2) examine the efficacy of therapeutic interventions and monitor program quality; and (3) supply individual clinical data to mental health providers for use in treatment planning and monitoring. Data for 242 subjects receiving outpatient services for sexual, physical, or emotional abuse and neglect have been collected. Analysis is in terms of the three program goals. Concerning the goal of providing descriptive data, although assessments were conducted on only 60 percent of patients, data have been collected on demographics, maltreatment history, mental health service use history, and treatment expectancies, and mental health and family problems and competencies. Concerning use for assessing therapeutic efficacy, follow-up data have been collected for only 59 youth and their families. Concerning supplying individual clinical data to mental health providers, clinicians have reported satisfaction with assessment summaries. (Contains 16 references.) (DB)
