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.

Gambling Disorder Screening Day (GDSD) occurs on the second Tuesday of March annually. This events is modeled after National Alcohol and Depression Screening Days, which research shows increase awareness and help-seeking for these problems. There has never been a study of the impacts of GDSD on its participants. The event is growing in popularity across Massachusetts, the U.S., and around the world, which makes its assessment imperative. Gambling operators might be able to support independent public health interventions for safer gambling due to their reach (e.g., through email marketing lists) among gamblers. Operator involvement in such efforts would help fulfill their responsibility for promoting safer gambling and help-seeking. Although limited public health expertise and opposing financial interests limit the value of operators' direct involvement in public health intervention, the value of indirect support through promoting third-party public health efforts remains an open question. Accordingly, this study considers how gambling operators might contribute to gamblers' participation in GDSD, and how it compares to another technique (e.g., MTurk) that offers high engagement.

As the event grows in popularity, it is imperative to ensure that GDSD has the intended effects, especially for high-reach supporters, such as gambling operators. This is particularly important for different types of people who might be more or less receptive to operator-promoted GDSD events. The investigators might, for example, expect to observe differences depending upon individuals' race/ethnicity status. Individuals minoritized by race/ethnicity have distinct barriers to help-seeking, including previous healthcare discrimination, lack of culturally and linguistically appropriate care, and an absence of resources and treatment opportunities designed with their unique needs and cultures in mind. Operator-promoted GDSD events, therefore, might need to be tailored to ensure reach, receptivity, and responsivity among minoritized people.

This study will provide information that can shape future gambling industry involvement in public health events, and simultaneously, complete a large (i.e., over 2,000 individuals) gambling screening. In addition, the proposed research involves a novel collaboration with an industry partner to examine a new digital protocol for gambling screening and intervention. The findings will provide new information about the efficacy of online mass screening for gambling-related problems.

Study Aims:

1. Co-develop with the Hoosier Lottery a campaign to promote a new digital protocol for gambling screening and intervention study timed to coincide with GDSD 2024 promotion;
2. Use a longitudinal sample of greater-Indiana gamblers to evaluate differences in GDSD reach (i.e., numbers of individuals screened), receptiveness (i.e., post-screening ratings of clarity, informativeness, relevance and helpfulness), and responsivity (i.e., changes in post-screening reports of gambling behavior and safer play intentions and behaviors) for lottery-recruited and platform-recruited (i.e., MTurk) screening participants randomized to intervention or control groups, using baseline and 3-month follow-up surveys and purposeful sampling; and,
3. Conduct a moderator analysis to examine whether status as a minoritized group member interacts with recruitment pathway to shape participants' responsivity to the screening/intervention protocol.

Inclusion Criteria:

• To be eligible for this study, participants must (1) be at least 18 years old, (2) have gambled at least monthly during the past 12 months, and (3) reside in Indiana, Kentucky, Michigan, Illinois, or Ohio.

Exclusion Criteria:

• Being from outside of U.S.

The investigators will share data on the Division on Addiction Transparency Project website.

Following publication of associated papers.

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.
