The Psychometric Properties of the Online Gambling Symptom Assessment Scale (OGSAS)

Abstract

Over the last decade, many psychometric instruments have been developed that assess various online problematic behaviors. Despite the many scales assessing gambling disorder (and its equivalents), no instrument assessing the consequences of problematic online gambling currently exists. In order to assess the symptoms and consequences of online gambling disorder, the Gambling Symptom Assessment Scale (G-SAS) was modified and its psychometric properties were assessed using exploratory factor analysis. The data were collected from 326 undergraduate and graduate students from a large public Midwestern university in the USA. Results suggest that the newly developed Online Gambling Symptom Assessment Scale (OGSAS) is reliable and valid as regards assessing the symptoms of online gambling disorder.
