Abstract
INTRODUCTION: We aimed to develop the Online Game Addiction Scale (OGAS) and examine its properties. METHODS: Three hundred and twenty-seven secondary school students (92% males and 8% females) participated in this study. A draft scale that included 69 items was used for assessing its validity and reliability. The exploratory factor analysis was used for assessing construct validity, and Cronbach's alpha coefficient, Spearman-Brown split-half reliability, and test-retest reliability were used for assessing reliability. RESULTS: After performing the exploratory analyses, a three-factor structure comprising 21 items was obtained, which explained the 59% of variance. The factor loads of the items ranged from 0.606 to 0.876. Reliability analyses revealed that Cronbach's alpha coefficients ranged from 0.83 to 0.91, coefficients of the Spearman-Brown split-half reliability ranged from 0.88 to 0.94, and outcomes of the test-retest reliability ranged from 0.71 to 0.94. CONCLUSION: Our results revealed that OGAS is a valid and reliable tool that has adequate psychometric properties.
