BACKGROUND: The HoNOS has been developed as a routine measure of outcomes in mental health. AIMS: To explore the validity and interrater reliability of HoNOS in a first-onset psychosis follow-up study. METHOD: Between 1992 and 1994 we ascertained a cohort of all persons with first-onset psychosis. We re-assessed these people at 3 years (n = 166) with several outcome scales, including HoNOS. Patients' keyworkers also completed the HoNOS. We estimated concurrent validity by calculating correlations between HoNOS and other scales, and interrater reliability. RESULTS: Researcher HoNOS correlated highly with other scales (0.46 < p < 0.86; P < 0.001). Keyworker HoNOS correlations were lower (0.41 < p < 0.51; P < 0.05), but still significant for all scores except the HoNOS-social subscale (0.12 < p < 0.28). Agreements between researcher and keyworker HoNOS were modest (0.47 < ICC < 0.85). CONCLUSIONS: In this research cohort HoNOS correlates well with established outcome scales. Keyworker ratings show similar, but weaker, relationships; its use in routine settings may require further training for calibration of severity.
