The receiver operating characteristic (ROC) curve of the PHQ-9 and PHQ-2 versus the SCID-I for a depression diagnosis. doi:10.1371/journal.pone.0151042.g002 Based on examination of indicators as Youden's index, sensitivity, specificity and AUC, the score of 8 for PHQ...
Comparison of Sensitivity and Specificity for PHQ-2 ≥ 2 in Combination With PHQ-9 ≥ 5 to 15 Versus Sensitivity and Specificity for PHQ-9 ≥ 5 to 15, Among Studies That Used a Semi-structured Diagnostic Interview as the Reference Standard eTable 7. QUADAS-2 Ratings for Each Primary Study...
Thus, the primary objectives of our IPD meta-analyses are to determine the diagnostic accuracy of the PHQ-9, PHQ-8, and PHQ-2 to detect MDD among adults across all potentially relevant cutoff scores. Secondary analyses involve assessing accuracy accounting for patient factors that may influence ...
The PHQ9 is acceptable, and as good as longer clinician-administered instruments in a range of settings, countries, and populations. More research is needed to validate the PHQ2 to see if its diagnostic properties approach those of the PHQ9....

In secondary analyses, we will adjust estimates of sensitivity and specificity for age (<60 years versus ≥60 years), sex, and the presence or absence of medical comorbidity. This will allow an estimation of whether the sensitivity and specificity calculated based on the optimal cutoff identified...
To summarize the psychometric properties of the PHQ2 and PHQ9 as screening instruments for depression. We identified 17 validation studies conducted in pri
This is the first study that investigates the responsiveness of the Patient Health Questionnaire-9 (PHQ-9), a standard 9-item self-report depression scale, to antidepressant medication. Authors analyzed data from 1,788 depressed outpatients (66.8% women; mean age, 50.3 years), participating in ...
which we observed a pattern of discordance with our two primary outcome measures; the Beck Depression Inventory (BDI-II) classified patients as moderately severe at the end of treatment, whilst the Patient Health Questionnaire (PHQ-9) classified these same patients as being only mildly depressed. ...
While some studies have reported a two-factor structure [67] and found greater diagnostic accuracy using the PHQ9-CA subscale compared to the PHQ-9/S [20] (although the diagnostic accuracy of the PHQ9-CA was similar to the entire PHQ-9), several others suggest a unidimensional factor ...
