Abstract

Purpose The aim of this study was to determine the reliability and validity of a Chinese version of the Patient Health Questionnaire (PHQ-9) for the purpose of screening major depressive disorder (MDD) among primary care patients in Taiwan.Method A total of 1954 primary care patients completed the PHQ-9. Patients (n = 1532) were interviewed using the Schedule for Clinical Assessments in Neuropsychiatry and 17-item of Hamilton Rating Scale. Subsample cases were retested within 2 weeks.Results The PHQ-9 had a good internal consistency (α = .80) and test-retest reliability (intraclass correlation coefficient = 0.87). A principal component factor analysis yielded 1-factor structure, which accounted for a total of 42.0% of the variance. The PHQ-9 was significantly correlated with the external validators such as the 17-item of Hamilton Rating Scale and the Short Form of the Quality of Life Enjoyment and Satisfaction Questionnaire (P < .001). Using the Schedule for Clinical Assessments in Neuropsychiatry interview as the criterion standard, a PHQ-9 score of 10 or higher had a sensitivity of 0.86 and a specificity of 0.94 for recognizing MDD. The screening accuracy of the 2 items version, PHQ-2, was also satisfactory (scores ≥ 2: sensitivity 0.88; specificity 0.82). The single-question screen, PHQ-1 (depressed mood), was 78% sensitive and 93% specific for detecting MDD (score ≥ 2).Conclusion The PHQ-9 and its 2 subscales, PHQ-2 and PHQ-1, seem reliable and valid for detecting MDD among Chinese primary care patients.

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.
