Growing evidence suggests that social media overuse can take a pathological form, and users can exhibit behaviors similar to those appearing in several types of addiction. The aim of this study was to validate the Greek version of the Social Media Disorder Scale (SMDS) among young adults. An online survey was conducted among Greek adults, aged 18-29 years old. A total of 251 respondents voluntarily participated. Internal consistency, criterion, and construct validity were examined. Results suggest that the Greek version of SMDS shows good psychometric properties. Internal consistency was above the acceptable margin, with a satisfying Cronbach's a coefficient. Correlations with other addiction-related constructs were found to be moderate. Construct validity of the scale was evaluated with exploratory factor analysis. Exploratory factor analysis resulted in a single factor model, which explained almost half of the total variance. The Greek version of SMDS is a psychometrically sound and valid instrument, which researchers and practitioners can use to assess social media addiction in young adults. 收起
