Background: The Problematic Online Gaming Questionnaire (POGQ) is an 18-item self-rated measure designed to assess the degree of problematic online gaming. This study translated the POGQ into Japanese (POGQ-J) and examined the POGQ-J’s factor structure, validity, and reliability for a Japanese population. Method: A total of 285 undergraduate students (128 males, 157 females, Mage=19.66, SD=1.36) participated in this study. Results: A confrmatory factor analysis indicated the appropriateness of the POGQ-J’s six-factor structure, χ2(129)=106.027, p<.931; CFI=.957; RMSEA=.040; SRMR=.054. Regarding convergent validity, the POGQ-J was found to be related to the time spent on online gaming (r=.309), the Game Addiction Scale for Adolescents (r=.824), and Young’s Internet Addiction Test (r=.581). Finally, the POGQ-J was found to have a high test–retest reliability. Conclusions: The POGQ-J is valid and reliable for assessing problematic online gaming in a Japanese population.
