Objective: There is a limited number of instruments to measure online gambling disorder among the Turkish population. Online Gambling Disorder Questionnaire is a 5-point Likert-type, self-report tool that evaluates problematic online gambling frequency and duration. This study aimed to assess The Turkish Version of the Online Gambling Disorder Questionnaire in a non-clinical sample.

Methods: This research is conducted on students of Ankara Yıldırım Beyazıt University Vocational School of Health Services. In the first-phase, content validity and in the second phase, construct, concurrent validity, internal consistency, and test–retest reliability were assessed. The questionnaire was completed online, and informed consent was obtained from the participants. The following instruments were used: Online Gambling Disorder Questionnaire, Internet Gaming Disorder Scale, and Generalized Problematic Internet Use Scale.

Results: A total of 243 (77.1%) of 315 subjects who participated in the study were women, and their mean age was 20.49 ± 2.54 years. The Cronbach’s alpha coefficient of the Online Gambling Disorder Questionnaire was found to be 0.939. In validity analysis, the Kaiser–Meyer–Olkin value was determined to be 0.887 (Bartlett sphericity test; P < .001) and was found to be compatible with factor analysis. In investigation of the co-test validity of the Online Gambling Disorder Questionnaire, as scores on the Online Gambling Disorder Questionnaire scale increased, scores on the Internet Gaming Disorder Scale-20 and Generalized Problematic Internet Use Scale increased in women (r = 0.214, P < .001 and r = 0.161, P < .05; respectively) but did not change in men (r = 0.115, P > .05 and r = 0.032, P > .05; respectively).

Conclusion: In general, the results suggest that the Online Gambling Disorder Questionnairehas a stable and unidimensional structure. Preliminary psychometric results indicate that the Online Gambling Disorder Questionnaire has good validity and reliability properties.
