* For each scale three cut-off points are highlighted in bold type: the optimal cut-off point with the best balance between sensitivity and specificity, the best lower cut-off point with a sensitivity ≥0.85, and the best higher cut-off point with a specificity ≥0.85 4DSQ = Four-Dimensional Symptom Questionnaire HADS = Hospital Anxiety and Depression Scale PPV = positive predictive value NPV = negative predictive value |
