The aim of this study was to develop and validate a scale to measure computer and videogame addiction. Inspired by earlier theories and research on game addiction, we created 21 items to measure seven underlying criteria (i.e., salience, tolerance, mood modification, relapse, withdrawal, conflict, and problems). The dimensional structure of the scale was investigated in two independent samples of adolescent gamers (N = 352 and N = 369). In both samples, a second-order factor model described our data best. The 21-item scale, as well as a shortened 7-item version, showed high reliabilities. Furthermore, both versions showed good concurrent validity across samples, as indicated by the consistent correlations with usage, loneliness, life satisfaction, social competence, and aggression.

The association between Internet addiction and psychiatric disorder: A review of the literature

Since the mid-1990s, there have been frequent reports of individuals whose use of the computer and internet is problematic. Given the recent expansion and the expected increase in internet availability and usage in the coming years, it is important that healthcare professionals be informed about this behavior and its associated problems. Recently, psychological and psychiatric literature has described individuals that exhibit problematic internet use who often suffer from other psychiatric disorders. In the face of this comorbidity, it is essential to evaluate whether these individuals represent a distinct class of disorder, or a manifestation/coping mechanism related to other underlying diagnosis. In either event, problematic internet use negatively impacts social and emotional functioning. Based on the current limited empirical evidence, problematic internet use may best be classified as an impulse control disorder. It is therefore imperative that problematic internet use be appropriately identified among symptomatic individuals. For these reasons, we propose specific diagnostic criteria that will allow for consistent identification and assist in further study of this behavior.
