The current study explored the relationship in a general population sample between problem gambling severity and cognitive distortions about gambling. A representative sample of problem gamblers (N = 766) was asked about cognitive distortions related to gambling. A positive association between gambling severity and cognitive distortions emerged, even when the variables associated with participants' demographic characteristics were accounted for. The current study demonstrates that the relationship between problem gambling severity and cognitive distortions does exist in the general population of problem gamblers. This finding emphasizes the key role that cognitive distortions may play in the development and maintenance of pathological gambling.
