GamTest is a feature of the responsible gambling tool PlayScan. It is an online self-rating measure to assess one’s gambling behaviour and negative consequences from gambling. GamTest has been found to work well for people with high-risk gambling, but not for people with low-risk. In this study, the researchers explored how to improve GamTest for use with people with low-risk gambling. Data from 2,234 Swedish adults who spent a low amount of money on gambling were analyzed. The results showed that GamTest could be adapted by shortening it to nine items (from 15 items) and using a scale ranging from 1 to 7 (instead of 1 to 10). Gender appeared to affect how people responded to three items of GamTest.
