The purpose of this study was to determine the factor structure underlying responses of psychiatric outpatients to the Health Opinion Survey HOS, and to assess variations in those dimensions among diagnostic subgroups. The sample was composed of 2,168 enlisted Navy personnel with modal age of 19-20 years. Principle components analysis yielded three interpretable dimensions Depression, Anxiety, and Somatic Concerns. The salient variables defining each component were item analyzed to produce psychometrically acceptable subscales and the relationships between scores on the HOS subscales and clinical diagnosis were explored. It was found that 1 there was significant variation across diagnoses on each of the three subscales 2 for each scale there was a notable difference between more disturbed and less disturbed outpatients and 3 there was consistency in the relative scoring positions of the several diagnostic groups on HOS subscales. The HOS dimensions which emerged had both empirical and clinical validity, and the factor structure associated with the patient sample evidenced greater differentiation than that previously reported for nonclinical groups. It was concluded that the HOS subscales have potential clinical usefulness and warrant further development and refinement.
