Validation of the Japanese version of the Patient Health Questionnaire-4 (PHQ-4-J) to screen for depression and anxiety.

ABSTRACT:

Objective

We aimed to validate the Japanese version of the Patient Health Questionnaire-4 (PHQ-4-J). People in Japan, especially healthcare workers (HCWs) suffer from high rates of mental health symptoms. The PHQ-4 is an established ultra-brief mental health measure used in various settings, populations and languages. The Japanese version of the PHQ-4 has not been validated.

Methods

Two hundred eighty people in Japan (142 HCWs and 138 from the general public) responded to the PHQ-4-J. Internal consistency, and factorial validity were assessed using confirmatory factor analysis (CFA) and Multiple Indicators Multiple Causes (MIMIC) models.

Results

Internal consistency was high (α = 0.70-0.86). CFA yielded very good fit indices for a two-factor solution (RMSEA = 0.04, 95
