Abstract

Objective To assess the performance of the Japanese version of the Patient Health Questionnaire-9 (J-PHQ-9) for depression in primary care.Methods Participants in both phases completed the J-PHQ-9, while patients in the second phase also completed the SF-8 (the short form for the health-related QOL scale SF-36). Subjects (n = 284; male = 107, female = 177) had to return the questionnaires to their health care professional within 48 hours and undergo a diagnostic evaluation interview based on the Japanese version of M.I.N.I-Plus.Results 93 patients were diagnosed as having major depressive disorder (MDD). In the J-PHQ-9, the optimal cutpoint ≥ 10 had sensitivity of 90.5% and specificity of 76.6%. As for the categorical algorithms, the sensitivity was 80.6%; specificity was 89.5%, and a positive likelihood ratio of 7.7. The Stratum-specific likelihood ratios (SSLRs) of the J-PHQ-9 scores of 0-9, 10-14, 15-19, and 20-27 for major depression were 0.10 (95% CI: 0.05-0.20), 1.67 (95% CI: 1.02-2.76), 5.41 (95% CI: 2.87-10.22), and 11.98 (95% CI: 5.39-26.63), respectively. The relationship between the severity of J-PHQ-9 and the MCS of SF-8 was significant (χ 2 ＝ 85.72, df = 4, P ≤ 0.0001).Conclusions This study has validated the J-PHQ-9 as a useful tool for the assessment of MDD in primary care in Japan.

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.
