Gambling Disorder Clinical Trial
Official title:
Developing and Testing the Effectiveness of a Novel Online Integrated Treatment for Problem Gambling and Tobacco Smoking: A Randomized Controlled Trial
Research has shown that problem gambling and tobacco smoking are highly comorbid. Problem gamblers who smoke tend to: have more severe gambling problems, experience stronger gambling urges, have other mental disorders, bet larger sums of money, spend more time in gambling activities, and have greater financial problems. Accordingly, it might be helpful to reduce your smoking as well, while you are trying to get a grip on your gambling. Previous studies have treated gambling on its own or tobacco smoking on its own. To date, there has not been a treatment that has targeted treating both at the same time. Considering how often these conditions occur together, it is important to see if combining their treatment results in beneficial outcomes. In the current research, the researchers aim to design and test an online, self-help intervention for co-occurring problem gambling and tobacco smoking. It will draw on strategies from Cognitive Behavioural Therapy (CBT) and Motivational Interviewing (MI) - both which have been shown to be successful in treating problem gambling and tobacco smoking. These outcomes will be compared to a group that receives treatment for problem gambling only. This research will provide insight into a potential new intervention for treating two highly co-occurring conditions.

Primary | Change in number of days gambled | Timeline Follow-Back (TLFB; Sobell & Sobell, 1992) - designed to assess the number of days gambled during a 30-day period. The TLFB has been shown to provide reliable and valid estimates of gambling behaviour, and is widely used in basic and treatment studies. | Participants will be assessed using the TLFB at three time points: at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Primary | Change in money spent gambling | TLFB designed to assess money (in dollars) spent gambling during a 30-day period. | Participants will be assessed using the TLFB at three time points: at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Primary | Change in time spent gambling | TLFB designed to assess the time spent gambling (in minutes) during a 30-day period. | Participants will be assessed using the TLFB at three time points: at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Secondary | Gambling symptom assessment | Brief self-report questionnaire with questions about gambling symptoms | Change in score from beginning of program (baseline T0) at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Secondary | Problem gambling severity | Brief self-report questionnaire with questions about gambling severity | Change in score from beginning of program (baseline T0) at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Secondary | Cigarette use | TLFB designed to assess the number of cigarettes smoked during a 30-day period. | Participants will be assessed using the TLFB at three time points: at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Secondary | Point Prevalence for Abstinence | Percentage of participants who remained abstinent from smoking in the 30-days prior to each assessment | Percentage of people at baseline (T0),immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). | |
Secondary | Nicotine dependence symptoms | Brief self-report questionnaire with questions about nicotine dependence | Change in score from beginning of program (baseline T0) at baseline (i.e., prior to treatment; T0), immediately following the 8-week treatment (T1), and at follow-up (i.e., 24 weeks from baseline, 16 weeks from end of treatment, T2). |
