Validation of the Instagram Addiction Scale in Greek Youth

Instagram is one of the fastest growing social networking platforms. A body of evidence suggests that Instagram problematic use and addiction have negative effects on the psychological well-being of young people. The Instagram Addiction Scale, a self-report tool assessing Instagram problematic use and addiction, has been developed recently. The aim of the present study was to validate the Instagram Addiction Scale in the Greek language and to assess its psychometric properties. An online and on-print self-report survey was conducted among Greek youth, aged between 18 and 24 years. The survey included the Instagram Addiction Scale, the Rosenberg Self-esteem Scale, the Perceived Stress Scale, and the Big Five Inventory. A total of 967 respondents participated in the study. The analysis suggested that the Greek version of the Instagram Addiction Scale has good psychometric properties. The principal component factor analysis for construct validity generated two subscales as the original instrument: social effect and impulsion. Internal consistency for the two subscales and the scale’s total score was satisfactory, with Cronbach’s α at 0.76, 0.85 and 0.88, respectively. Correlation analyses revealed positive associations between the perceived stress scale and social effect, and the Instagram Addiction Scale’s total score (p<0.0001 and p=0.002 respectively). This is the first study validating the Instagram Addiction Scale in Greek youth, which can be used by researchers and practitioners for the evaluation of youth problematic use of Instagram.
