Interpretation & limitations
- Clinical score is the mean of completed, correctly reverse-scored items multiplied by 10 (0–40). Higher scores indicate greater overall distress. No universal diagnosis or safety conclusion is produced. Individual risk responses require review regardless of total. Only the overall clinical score is implemented; wellbeing, problems, functioning, risk and non-risk domain scores are not calculated.
