Prevention Messages for EGMs: Effects on Behaviours and Cognitions

Summary

The goals of this randomized controlled trial are to test the manifold effects of prevention pop-up messages on participants' behaviours, cognitions and affects. 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.

BEHAVIORAL

Prevention pop-up messages

Messages are shown full screen on the EGM's play screen on a fixed presentation schedule. Clock of the gambling session starts the first time the participant puts money in the EGM. From this event, messages are shown at those timepoints: \[1\] +10 minutes; \[2\] +40 minutes; \[3\] +70 minutes; \[4\] +100 minutes. Messages block the screen for 15 seconds before automatically closing. Up to 4 different messages are presented during the gambling session. Order is determined by sortition without replacement. Messages have a warning heading "Caution!". Content is, from top to bottom: (a) time spent gambling from beginning; (b) warning that gambling could lead to serious monetary loss; (c) 1 of 4 self-appraisal phrases about current gambling behaviour; (d) advice to the participant that a break could help choose what is best for them; (e) countdown before the message closes itself; (f) Health department logo is shown in the lower right corner as a more "neutral" endorsement of the messages.

BEHAVIORAL

Mandatory time limit

Activated either when (a) the previous time limit is up; or (b) the player bank meter reaches $0. When the previous time limit is up, a pop-up takes up the upper third of the play screen and requires the player to set a new time limit using one of five choice buttons (four firsts buttons: 15, 30, 45 or 60 minutes; fifth button: cash out, which prints a receipt and ends the gambling session). As the EGM cannot track who is playing, there are no limits on consecutive gambling sessions. When the player's bank meter reaches $0, the the pop-up described above appears as soon as new money is inserted in the EGM, no matter if the previous time limit is up or not.

BEHAVIORAL

Responsible gambling information

Located in a submenu accessed through a button on the main touch screen. This open a window which contains basic information on randomness and responsible gambling advice. The information is presented in small white font on a black background.

DEVICE

Electronic gambling machine (model IGT GL20)

EGM model currently in use in Quebec, Canada, the location where this study is conducted. The EGMs used in this study are fully functional and unaltered except for the presentation of prevention pop-up messages in the experimental arm of this study. These machines are equipped with basics responsible gambling features, the two main ones described in this section (i.e. "Mandatory time limit"; "Responsible gambling information"). Wins/losses sequence is fully randomized and not determined beforehand.

DEVICE

Square terminal

This terminal allows for buying non-alcoholic beverages (soft drinks or coffee) and chips during the experimentation. This is done to enhance the realism of the bar setting. It also allows for real cash withdrawal from bank account during gambling session. Quebec's code of conduct for EGMs commercialization prohibits retailers from having an ATM near their EGMs, and prohibits them from lending money to consumers or withdrawing cash for them to gamble. However, this rule is not always followed in practice. For this study, participants will be allowed to withdraw from their bank account, at the bar counter, if they ask for it. However, this will not be offered to them upfront.
