Fast screening of depression in cancer patients: the effectiveness of the HADS

In oncology clinics, there is an increasing need for fast and accurate screening scales and procedures in order to evaluate cancer patients for depression. The present study investigated the comparative effectiveness in recognising depressed patients of the Hospital Anxiety and Depression Scale (HADS), a self-report screening scale, and the Montgomery-Asberg Depression Rating Scale (MADRS), a semi-structured clinician-rated scale, in 151 patients affected by mixed cancer pathologies. With the MADRS, 73.5% of the patients were identified as depressed, whereas the HADS identified 36.4% and 58.3% as depressed, using the cut-offs of 11 and 8 respectively. The results suggest moderate agreement between the MADRS and the HADS when a cut-off of 8 is used (K-test: 0.44), while using a HADS cut-off of 11 gave a significantly higher underestimation of depressed patients (K-test: 0.29). In conclusion, the results suggest that the HADS can be useful as a sufficiently accurate first-step screening tool for depression in mixed oncology settings.
