Diagnostic accuracy and practical utility of depression screening questionnaires across renal replacement therapy modalities

The BDI-II, BDI-FS, and HADS-D are useful for depression screening in renal populations, though the HADS-D demonstrated reduced performance in home dialysis. Standard cut-offs were inadequate, and modality-specific thresholds improved diagnostic accuracy. The BDI-FS, combining strong accuracy with brevity and ease of use, emerged as the most efficient tool for routine screening across RRT modalities.
