Psychometric properties of the Problem Video Game Playing scale in adults

Abstract

IntroductionInternet Gaming Disorder (IGD) was introduced for the first time within the “conditions for further study” in the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association, and a systematic review has concluded that the only available instrument for its measurement is the Problem Video Game Playing scale (PVP). Nevertheless, this scale was presented as a diagnostic tool for adolescents, and to date no study has analyzed its properties amongst adults. ObjectiveThe aim of the study was to analyze and compare the diagnostic and psychometric properties of the PVP in adult and adolescent gamers. MethodTwo samples of adult (n=525) and adolescent (n=384) gamers completed a survey including patterns of play, PVP, Severity of Dependence Scale, and other measures of playing to excess. ResultsConfirmatory factor analyses revealed that the scale presents a one-factor structure that is similar to that of the original version, both in adults and adolescents. Construct validity was supported by highly significant associations between the PVP and all alternative measures of playing to excess. On the other hand, reliability values were lower than in previous studies. ConclusionsThe PVP scale's properties are appropriate for the measurement of problem video gaming in adults as well as in adolescents, but studies with clinical assessments are still needed before any cutoff value for diagnosis can be established.
