Superstitious beliefs in gambling among problem and non-problem gamblers: preliminary data.

Superstitious beliefs, defined as a strong conviction based on the erroneous perception of a cause-effect association between two independent events, are considered to play an instrumental role in the maintenance of gambling behaviour. In this preliminary study, responses to eight items assessing superstitious beliefs were compared among 56 electronic gaming machine (EGM) problem gamblers, 22 non-problem EGM and 23 non-EGM non-problem gamblers. Results suggested that problem gamblers endorsed more superstitious beliefs than non-problem gamblers and that such beliefs were correlated with gambling intensity. Further research is required to determine if superstitious beliefs represent a vulnerability factor for the development of problem gambling or emerge as a consequence of involvement in gambling.
