Problem Gambling

Brief summary

This application involves a multi-stage study with the ultimate goal of developing an online treatment service for problem gamblers. We will recruit up to 100 problem gamblers, and offer problem gambling treatment services to them entirely over the internet. The program will be evaluated based on uptake, experience of the participants, and pre-test vs post-test differences in gambling and well-being.

Detailed description

Disordered gambling is now recognized as a behavioral addiction. Although the physical consequences of the disorder are very mild, the financial and emotional costs can be enormous. This application involves a multi-stage study with the ultimate goal of developing an online treatment service for problem gamblers. This project was originally designed to take place over a three-year period but has been condensed into two. Part one was scoping review. Part two involved focus groups with service providers and people experiencing gambling problems. Part three will gather some general population information on two on going population survey's run by our research team. Part four Involved key informant interviews, and part five would be the development and evaluation of a pilot online treatment service. This application deals with part five of the overall project, Parts two and four were conducted as 025-2017. In this study, we will recruit up to 100 problem gamblers, and offer problem gambling treatment services to them entirely over the internet. The program will be evaluated based on uptake, experience of the participants, and pre-test vs post-test differences in gambling and well-being. The data reported here are related to part 5 only. Due to funding cuts, we were only able to include 2 people in the completed study.

Design outcomes

Primary

MeasureTime frameDescription
Changes in Gambling Frequency as Measured by Self Reported Frequency on 12 Different Types of Gambling.Change from baseline to 3 monthsLevel of gambling frequency was measured using self reported frequency on a 7 point scale on 12 types of gambling. We used the maximum frequency across the twelve types of gambling so that if they reported participating in 5 types of gambling ranging from once per year (score of 1) to everyday (score of 7), we would score the person as 7. This way the measure was sensitive to changes in the most problematic frequent form of gambling for that person. Lower levels of gambling frequency after 12 months would be a positive outcome. To score frequency we computed each person's highest frequency for a range from 0 (none) to 7 (everyday) with higher numbers indicating more frequent gambling. The same was done for their post-test scores. We computed the difference score of post-test from pre-test which could range from 7 to -7 with negative numbers indicating improvement (reduced gambling participation).
Changes in Number of Games PlayedChange from baseline to 3 monthsNumber of games played was measured using a self report measure of participation in 12 games (see frequently above). Fewer games played would be a positive outcome. Possible range is from 0 to 12. We computed the difference score from pre-test to post-test which could range from 12 to -12 with negative numbers indicating improvement (reduced gambling participation).
Changes in Mindful Attention Awareness Scale (MAAS; Brown & Ryan, 2003).Change from baseline to 3 monthsMindfulness was measured using the Mindful Attention Awareness Scale (MAAS; Brown & Ryan, 2003). Range 1 to 6 based on average score per item; higher scores mean greater mindfulness. For the evaluation we computed the difference of the post-test and the pre-test for a range from 6 to -6 with positive numbers indicating an improvement in mindfulness.
Changes in Kessler-6 (K6; Galea, et al., 2007).Change from baseline to 3 monthsThe Kessler-6 measures psychological distress (K6; Galea, et al., 2007). Higher scores indicate more psychological distress. Score 0 to 25 with scores over 8 indicating moderate psychological distress. We are predicting lower levels of psychological distress at 3 follow-up as measured using the Kessler-6 (K6; Galea, et al., 2007). For the evaluation we computed the difference of post-test from pre-test with a range from 25 to -25 with negative numbers indicating an improvement.
Changes in Problem Gambling Severity Index (PGSI; Ferris & Wynne, 2001).Change from baseline to 3 monthsGambling problems are measured using PGSI (Ferris & Wynne, 2001). Each of the 9 item is measured on a 4 point scale from never (0) to almost always (3). The total ranges from 0 to 27. Higher scores indicate more gambling problems; Lower scores at followup would be a positive outcome. Total scores form 3 to 7 indicate moderate gambling problems; scores 7 or higher indicate severe gambling problems. In this study we subtracted pre-test scores from post test scores to compute a change score which would range from27 to -27 with higher number indicating a worse outcome and negative numbers indicating a positive outcome.
