To validate the Japanese version of the Patient Health Questionnaire against the Mini-International Neuropsychiatric Interview-Plus in Japan 131 patients in 4 primary care settings and 2 general hospital settings participated. These patients completed the Patient Health Questionnaire and returned it to their physician within 48 hr. Subsequently, the subjects underwent a diagnostic evaluation interview based on the Mini-International Neuropsychiatric Interview-Plus by an interviewer blind to the results of the Patient Health Questionnaire screening. The Patient Health Questionnaire diagnosis was characterized using kappa values between 0.70 and 1.0 for Somatoform Disorder, Major Depressive Disorder, Panic Disorder, Bulimia Nervosa, Alcohol Abuse/Dependence, and Premenstrual Disorder. Sensitivities, specificities, and negative predictive values were very good (between 0.84 and 1.0) for the first 4 diagnoses but not Alcohol Abuse/Dependence or Premenstrual Disorder, as were the Positive predictive values (between 0.78 and 1.0). Findings show very good concordance of the Japanese version of the Patient Health Questionnaire with the Japanese version of the Mini-International Neuropsychiatric Interview-Plus.

"In this study, we used the Japanese version of the PHQ-9. The Japanese version of the PHQ-9 also has excellent validity in primary care and in psychiatric settings  . A major depressive episode is diagnosed in two ways using the PHQ- 9: it is diagnosed by a diagnostic algorithm and a summary score . "
[Show abstract][Hide abstract] ABSTRACT: The aim of our study was to reveal the personality traits of individuals with major and other depressive episodes among the young adult population. Furthermore, character traits of individuals with ideas of suicide or self-harm were also investigated in this study.
The subjects of this study were 1421 university students who completed the Patient Health Questionnaire (PHQ-9) and the Temperament and Character Inventory (TCI). The subjects were divided into three separate groups: the major depressive episode group (N=41), the other depressive episode group (N=97), and the non-depressive controls (N=1283). This separation was achieved using the PHQ-9 algorithm diagnosis. We compared the TCI scores using an analysis of variance. Moreover, the Cochran-Armitage trend test was used to determine the diagnosis, ideas of suicide or self-harm, and analysis of character profiles.
The major depressive episode group had significantly higher HA (P<0.001), lower RD (P<0.001), lower SD (P<0.001), and lower C (P<0.001) scores than non-depressive controls. The other depressive episode group had significantly higher HA scores (P<0.001) and lower SD scores (P<0.001) than non-depressive controls. The Cochran-Armitage trend test revealed that the prevalence of depressive episodes decreased as the character profiles matured (χ(2)trend=57.2, P<0.0001). The same tendency was observed in individuals who had ideas of suicide or self-harm (χ(2)trend=49.3, P<0.0001).
High HA and low SD scores were common personality traits among young adults with major depressive episodes. Furthermore, the immaturity of character profiles was clearly associated with depressive episodes and ideas of suicide or self-harm.
