The Reasons for Gambling Questionnaire (RGQ) is a self-report instrument containing 15 items to assess individual motives or reasons to gamble. This study presents psychometric data on the Swedish version of the instrument with a focus on factor structure. A Swedish sample (N = 19,530) was screened for risk gambling with the Lie/Bet questionnaire, the effective study sample (n = 237) consisting of respondents with a positive answer on this questionnaire who agreed to participate in an additional postal questionnaire and had no missing items on the RGQ. The originally proposed subscales of the instrument fit the data poorly and a slightly different five-factor solution was suggested. We conclude that the RGQ needs further revision and that the dimensionality of gambling motives is a question that deserves further attention.
