In South Australia (SA) problem gambling is mainly a result of the widespread availability of electronic gaming machines. A key treatment provider in SA offers free cognitive and behavioural therapy (CBT) to help-seeking problem gamblers. The CBT program focuses on the treatment of clients' urge to gamble using exposure therapy (ET) and cognitive therapy (CT) to restructure erroneous gambling beliefs. The aim of this study was to explore treatment specific and non-specific effects for CT alone and ET alone using qualitative interviews. Interviewees were a sub-sample of participants from a randomised trial that investigated the relative efficacy of CT versus ET. Findings revealed that all interviewees gained benefit from their respective therapies and their comments did not appear to favour one therapy over another. Both treatment specific and treatment non-specific effects were well supported as playing a therapeutic role to recovery. Participants' comments in both therapy groups suggested that symptom reduction was experienced on a gambling related urge-cognition continuum. In addition to symptom improvement from therapy-specific mechanisms, ET participants described a general acquisition of "rational thought" from their program of therapy and CT participants had "taken-over" their gambling urges. The findings also highlighted areas for further improvement including therapy drop-out.
