Validating the Gambling Functional Assessment—Revised in a United Kingdom sample

Abstract

The gambling functional assessment-revised (GFA-R) was designed to assess whether the respondent’s gambling was maintained by positive reinforcement or escape. The present study attempted to validate the GFA-R’s psychometric properties using United Kingdom (UK) university students and to compare the results to those from a sample of American university students. Two hundred seventy four UK students completed the GFA-R, and 153 also completed the South Oaks gambling screen (SOGS). Two hundred one United States (US) university students completed both measures. A confirmatory factor analysis indicated that the original model of the GFA-R provided an excellent fit for the UK data and internal consistency was high. These outcomes were similar, if not superior, to those from the US sample. SOGS scores strongly correlated with GFA-R escape subscale scores in both samples, replicating previous results. These findings indicate that the GFA-R is a valid measure for use in the UK, which is potentially useful to both practitioners and researchers. They also suggest that the strong relationship between endorsing gambling as an escape and measures of disordered gambling may be ubiquitous.
