Comparison of major depression classification odds of the Composite International Diagnostic Interview (CIDI) versus the Structured Clinical Interview for DSM (SCID)
The figure presents the aOR of major depression classification for the CIDI compared to the SCID for primary studies based on the PHQ-9, EPDS, and HADS-D and pooled estimates at standardized scores of −1, 0, 1, 2 and 3. The standardized scores of −1, 0, 1, 2 and 3 are approximately equal to scores of 0, 5, 10, 16 and 21 on the PHQ-9 (SD = 5.26); 1, 7, 13, 18 and 24 on the EPDS (SD = 5.58); and 1, 5, 9, 13 and 17 on the HADS-D (SD = 4.07). We present standardized scores from −1 to 3, because raw scores corresponding to standardized scores below −1 or above 3 would be negative or beyond the maximum scores of the included screening tools.
