As a severity measure, the PHQ-9 score can range from 0 to 27, since each of the 9 items can be scored from 0 (not at all) to 3 (nearly every day). An item was also added to the end of the diagnostic portion of the PHQ-9 asking patients who checked off any problems on the...

The median score of each item was 0, with inter-quartile range of 0–1. The total score of PHQ-2 ranged from 0 to 6 with a median score of 0. Reliability and item analysis The PHQ-9 had a Cronbach's alpha of 0.82, with the correlations between the total sc...
Often, these studies report results from a small range of cutoff points around whatever cutoff score is most accurate in that given study. When published data are combined in meta-analyses, estimates of accuracy for different cutoff points may be based on data from different studies, rather than...
Results: The Cronbach's α coefficient of the PHQ-9 was 0.839. The Pearson's correlation coefficient among the 9 items of the PHQ-9 scale was 0.160 ~ 0.578 (P < 0.01), and the Pearson's correlation coefficient between each item and the total score was at the range of ...
