Abstract

Objective The nine-item mood module of the Patient Health Questionnaire (PHQ-9) was developed to screen and to diagnose patients in primary care with depressive disorders. We systematically reviewed the psychometric literature on the PHQ-9 and performed a meta-analysis to ascertain its summary sensitivity and specificity.Methods EMBASE, PubMed and PsycINFO were used to search literature up to July 2006. Studies were included if (1) they investigated the diagnostic accuracy of the PHQ-9 and (2) the PHQ-9 had been compared with a reference test. The quality of the studies was appraised using the Quality Assessment of Diagnostic Accuracy Studies. We calculated sensitivity, specificity and confidence intervals for each included study. We used the random effects model to calculate the summary sensitivity and specificity.Results We found a sensitivity of 0.77 (0.71-0.84) and a specificity of 0.94 (0.90-0.97) for the PHQ-9. The positive predictive value in an unselected primary care population was 59%, which increased to 85-90% when the prior probability increased to 30-40%.Conclusion In primary care, the PHQ-9 is a valid diagnostic tool if used in selected subgroups of patients with a high prevalence of depressive disorder.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
