This study is conducted among regular EGMs' players (defined as having played EGMs at least once every two weeks for the past 12 months) who are not classified as probable pathological gamblers by the PGSI.After answering a series of short questionnaires by phone, participants are asked to schedule a gambling session which is done in a laboratory on the university's campus. This laboratory replicates a typical bar, and is equipped with real EGMs. Participants are recruited under the false pretense of giving their opinion on the realism of the bar replica, and on the overall feeling of the gambling session in it. They are told that: (a) they are free to gamble as much and for as long as they like; (b) they are allowed to take breaks; (c) gambling is to be done with their own money; (d) the only compensation for participation are the potential winnings made while gambling; (e) net winnings across their whole session are paid, but losses are real. There is only one participant at a time in the laboratory for the gambling session.After having stopped by their own volition (some exceptions apply, see "Detailed Description" for further details), participants are debriefed on the real goals of this study and reimbursed any incurred losses while gambling. They are then be asked to answer another series of questionnaires., conditionsModule conditions: Gambling, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: RANDOMIZED, interventionModel: PARALLEL, interventionModelDescription: Stratified block randomization assignment. Blocks are size 4 and strata are divided on problem gambling severity using PGSI categories. Two conditions:* Experimental: Regular gambling session + Prevention pop-up messages* Active Comparator: Regular gambling sessionThree assessment phases:* Pre-experiment. Telephone interview before the gambling session. Measures baseline characteristics and schedule the gambling session. Usually done within a couple of days following an application to participate.* Experiment. Gambling session in the laboratory. Behaviour is continuously measured starting with the first time the participant puts money in the EGM to participant choosing to end their gambling session. Duration is limited to 2 hrs (unbeknownst to participant). Session is scheduled days to weeks after the Pre-experiment, depending on participant's availability.* Post-experiment. Debriefing and post-experiment interview. Done right after the gambling session is ended., primaryPurpose: PREVENTION, maskingInfo masking: SINGLE, maskingDescription: Participants are recruited under the false pretense of evaluating the realism of a gambling session in a laboratory replicating a bar environment. While the participants in the experimental group should notice the novel prevention messages, before debriefing, for all they know, there are no groups to be assigned to. Therefore they would not be aware, that there are two different groups, nor that this study tests the effects of prevention pop-up messages.Note that masking becomes "open label" after debriefing. Indeed, after being informed of the true goals of this study, participants will easily be able to determine in which group they were assigned based on what occured during their gambling session. Though, gambling behaviours are recorded before debriefing and won't be affected by unmasking.There is no functional way to mask group assignment to the members of the research team. However, the randomization procedure assures that allocation is purely random., whoMasked: PARTICIPANT, enrollmentInfo count: 80, type: ESTIMATED, armsInterventionsModule interventions name: Prevention pop-up messages, interventions name: Mandatory time limit, interventions name: Responsible gambling information, interventions name: Electronic gambling machine (model IGT GL20), interventions name: Square terminal, outcomesModule primaryOutcomes measure: Gambling behaviour (between group) -
