NCT06235333

Brief Summary

The study is a randomized trial of gambling screening plus feedback (intervention) or gambling information (control) conditions, with data collection at baseline (T1) and a 3-month follow-up (T2). Two participant recruitment strategies (i.e., Hoosier Lottery cohort and MTurk Workers cohort) will allow the investigators to compare how recruitment source relates to post-intervention gambling behavior change intentions and assorted gambling-related behavior changes. The investigators also seek to understand how experiences with screening vary for minoritized and non-minoritized people who gamble.

Outcome Measures

Primary Outcomes (11)

  • Reach

    At Time 1, the investigators will count the number of individuals who elect to launch the GDSD screening protocol.

    Time 1 (March 12, 2024)

  • Protocol Feedback.

    At Time 1, the investigators will ask participants to indicate the extent to which they agree that specific parts of the GDSD protocol are (1) clear, (2) informative, (3) relevant, and (4) helpful. Participants will make ratings on a 5-point scale ranging from Strongly Disagree to Strongly Agree.

    Time 1 (March 12, 2024)

  • Gambling Frequency.

    At Time 1 and Time 2, the investigators will assess past three-months gambling behavior. The investigators will ask participants to indicate the frequency with which they engaged in six gambling activities (e.g., Lottery/Scratch Tickets; Poker, Casino Table Games; Sports; Slots/Keno; Other) in the past 3 months on a scale from Never (0) to More than Once a Week (6). For some analyses, the investigators will assign individuals a single 3-month frequency score (range 0-6) by identifying individuals' maximum frequency playing any game during the past three months.

    Time 1 (March 12, 2024) and Time 2 (June 12, 2024)

  • Gambling Intentions.

    At Time 1, the investigators will inquire about participants' future gambling intentions by asking them to report how much they expect they will gamble on six types of gambling games during the next three months using the same frequency scale adapted for future gambling.

    Time 1 (March 12, 2024)

  • Guidelines Compliance.

    At Time 1 and Time 2, the investigators will ask participants to report, to the best of their recollection, whether they have complied with three Lower Risk Gambling Guidelines \[LRGG; 21\] during the previous three months: (1) Gambled no more than 1% of household income before tax per month, (2) Gambled no more than four days per month, and (3) Avoided regularly gambling at more than two types of games. Participants will indicate that they have complied with a practice, have not complied, or do not know. For some analyses, the investigators will assign individuals a single compliance score (0-3) by summing the number of guidelines with which an individual complied during the past three months.

    Time 1 (March 12, 2024) and Time 2 (June 12, 2024)

  • Guidelines Intentions.

    At Time 1, the investigators will ask participants to report their intentions for following the three LRGG during the next three months. Participants will make ratings on a 5-point scale ranging from Extremely Unlikely to Extremely Likely.

    Time 1 (March 12, 2024)

  • Safer Gambling Practices.

    At Time 1 and Time 2, the investigators will ask participants to report, to the best of their recollection, whether they have engaged in six safer gambling practices \[21\] during the previous three months: (1) limit your consumption of alcohol, cannabis and other drugs while gambling; (2) limit your access to money; (3) schedule activities right after gambling sessions, which can set a limit on the amount of time you have to gamble; (4) think about how having gambling companions or gambling alone might impact you; (5) keep in mind how much money you are able to spend on entertainment when deciding how much to gamble; and, (6) plan ahead and set limits. Participants will indicate that they have engaged in a practice, have not engaged, or do not know. For some analyses, the investigators will assign individuals a single safer gambling score (0-6) by summing the number of safer gambling practices with which an individual engaged during the past three months.

    Time 1 (March 12, 2024) and Time 2 (June 12, 2024)

  • Safer Gambling Intentions.

    At Time 1, the investigators will ask participants to report their intentions for engaging in the six safer gambling practices during the next three months. Participants will make ratings on a 5-point scale ranging from Extremely Unlikely to Extremely Likely.

    Time 1 (March 12, 2024)

  • Help Seeking Behavior.

    At Time 1 and Time 2, the investigators will ask participants to report whether they engaged in gambling education and gambling help-seeking activities during the past three months. Participants will indicate Yes or No to whether they have engaged with (1) a gambling self-help workbook that can be completed anonymously online; (2) a gambling self-help workbook that was mailed to their home; (3) an online gambling helpchat; (4) a phone-based gambling helpline; (5) a gambling recovery podcast; (6) a gambling recovery smartphone app; (7) Gamblers Anonymous or other mutual support groups; (8) gambling "how to" books or services; or (9) professional treatment for gambling, including a more in-depth assessment of their gambling behavior. For some analyses, the investigators will assign individuals a single help seeking score (0-9) by summing the number of help-seeking activities with which an individual engaged during the past three months.

    Time 1 (March 12, 2024) and Time 2 (June 12, 2024)

  • Help Seeking Intentions.

    At Time 1, the investigators will ask participants to indicate their likelihood of engaging in the nine gambling education and gambling help-seeking activities during the next three months. Participants will make ratings on a 5-point scale ranging from Extremely Unlikely to Extremely Likely.

    Time 1 (March 12, 2024)

  • Positive Play Scale.

    At Time 1 and Time 2, the investigators will ask participants to complete the Positive Play Scale \[22\] on a 3-month timeframe. The investigators will calculate Cronbach's alpha and, if the investigators observe adequate internal consistency, the investigators will calculate its four subscale scores by summing.

    Time 1 (March 12, 2024) and Time 2 (June 12, 2024)

Masking Details
Through Qualtrics programming, individuals will be randomly assigned to an intervention or control group. Because this happens automatically, the investigators will not know assigned conditions until after data collection is completed. Participants will be aware of their condition because they will either participate in a screening or receive problem/responsible gambling information before completing a survey.

Intervention Model
PARALLEL
Model Details: There are two possible conditions: (1) intervention, which consists of a branching responsible/problem gambling information and gambling screening experience and (20 control, which consists of limited responsible/problem gambling information experience.
