This study examined the degree to which a literature review of evidence-based services identified services appropriate for the actual problems of youth involved in intensive public mental health services. The diagnostic profiles and specific intervention targets reported by treatment providers were coded to determine whether a relevant empirically supported treatment was identified in the literature by the Hawaii Evidence-Based Services Committee for each problem. Of the 2,197 youth with diagnostic information available, 721 youth (33%) had a pure diagnosis for which an evidence-based service was identified in the literature, and 1,953 youth (89%) had a primary diagnosis with a relevant evidence-based service. Of the 1,220 youth with treatment target information, 1,094 (90%) had 1 or more problem areas targeted for intervention with an identified evidence-based service; thus, the vast majority of youth receiving intensive public mental services experienced a mental health difficulty for which an evidence-based service was identified through a review of the empirical literature. Nevertheless, many youth had additional problems for which evidence-based services have not yet been identified through research.
