Study summary

It has been shown that self-excluded gamblers are very heavy gamblers, and that it is not possible to distinguish between those who report self-exclusion for addictive reasons and those who self-exclude for commercial reasons, which strongly suggests that all self-excluded people are "self-diagnosed" problem gamblers. Several studies converge in recognizing self-excluded people as problem gamblers who have lost control of their gambling and are seeking to protect themselves by taking action, self-exclusion, to change their behaviour and protect themselves.

Several reviews of the literature on interventions for problem gamblers have recently identified self-exclusion as an intervention for problem gamblers.

However, the effectiveness of the current self-exclusion system appears to be limited, particularly for short self-exclusions and for heavier gamblers.

Considering that self-exclusion is an intervention for and by people who have developed a gambling disorder, it currently consists exclusively of a behavioural intervention, in the sense that it prevents the behaviour. It would then be possible to optimize this intervention by enriching it with other components that have been shown to be effective with problem gamblers or in other addictions: a brief intervention including a motivational, cognitive approach, personalized normative feedback, referral to online help services (cresus and gambling infoservice), and repeated contact to suggest an extension of the self-exclusion period without having to return to the gambling environment. We hypothesize improved efficacy as measured by reduced gambling for longer after an initial optimized self-exclusion compared to self-exclusion with the standard procedure. Days will be randomized according to an a priori randomization list, not players.

Eligibility

Primary outcome measure(s)

• change in total net loss over the last 4 weeks, between the last 4 weeks prior to self-exclusion T0, and the last 4 weeks at 12 months T2 — between the last 4 weeks before self-exclusion T0, and the last 4 weeks at 12 months T2
