Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is Exposure therapy. Exposure is a specific form of cognitive behaviour therapy, known as a behavioural approach whereby the person/participant conducts tasks where they deliberately expose themselves to triggers or cues which elicit a gambling urge or in the case of anxiety disorders where exposure was invented to anxiety. The therapeutic model is that by repeating these exposure exercises daily or 3-4 times weekly (Cue Exposure Therapy CET), until the urge reduces by at least half in each session (this is called habituation) the person unlearns or extinguishes the urge to gamble. Participants (sports betting gamblers) are provided 1 session weekly for up to 10 sessions (10-12 weeks). During each session the therapist guides the participant to select triggers that elicit a gambling urge e.g., looking at the gambling app on their phone or a gambling advertisement for 20-40 minutes until the urge has reduced by at least half and then repeat this task daily until the urge extinguishes (habituation). The therapist and gambler create a hierarchy of triggers and these are addressed in a gradient from easy to difficult until all or most triggers/urges have been eliminated. Progress is monitored by the participant filling out homework sheets describing their tasks and urge as well as questionnaires at each session on gambling urge and gambling time and money spent. We have published a paper on 6 cases of sports betting addiction treated by the SA Statewide Gambling Therapy Service (SGTS). CET was provided face to face by experienced SGTS staff using a standardised workbook adapted for sports betting. In CET as described in the case studies, all urges to gamble are extinguished and the person gains control over their gambling either through abstinence or occasional gambling.

The phase 1 pilot proposal aims to recruit 40 participants from all areas of SA and provide CET using mobile phone or internet in contrast to those who have received the intervention from SGTS face in a clinic setting as described in the published 6 case studies. This would provide the data to inform a phase 2 national randomised controlled trial with funding sought from other states and/or NHMRC Partnership grant.

Secondary outcome [7] 411598 0
Qualitative data -Semi-structured interviews with purposefully chosen (age above and below 25, those who improved/recovered/those who dropped out/did not recover) 6 intervention participants 4 TOs and 1 therapists to determine recruitment barriers and enablers, acceptability and feasibility and any improvements to the intervention or delivery and recruitment. These components will be collected and analysed concurrently as a composite. Of particular interest will be the on-line and social media strategies used to recruit non help seeking sports betters. These interviews will be conducted by the RA using phone or videoconferencing with set open ended questions .
