A factor analysis was performed using 609 subjects, each of whom completed the 265 Hem self-report problem inventory. Factor analysis was used in this context as the logical first step in the development of the problem inventory. For the purpose of analysis, 240 of the Hems were used. Results suggest that there may be utility in further research involving the problem inventory. A literature review of current diagnostic issues, se 1 f-report inventory issues, diagnostic interviewing issues, and finally, self-report inventory development is included.
