Participants will be randomly assigned to play either InvestiDate (n=40), or the non-health related attention and time control condition multiplayer videogame (n=40).

HIV/STI Testing- partner will be used to test the hypothesis that individuals who play InvestiDate will report more HIV/STI testing and partner testing in comparison to the control condition. The investigators will conduct a longitudinal analysis using a hierarchical linear mixed models approach to compare participants in the intervention group to participants in the control group on reported participant and partner HIV/STI testing from baseline across all follow-up assessments.

The CUSES is a 28 item self-report questionnaire which elicits responses using a five-point Likert scale format, ranging from 'strongly disagree' to 'strongly agree'. 10 of the 28 items were administered and scores were summed for each item for each participant. Each of the responses is scored as follows: 'strongly disagree' = 0, 'disagree' = 1, 'undecided' = 2, 'agree' = 3 and 'strongly agree' = 4. The possible range of scores is 0-40, with higher scores indicating greater self-efficacy.

The SRBBS measure includes 3 items (e.g., "How sure ate you that you could use a condom correctly or explain to your partner how to use a condom correctly?") measured on a scale from 1 (not sure at all) to 5 (extremely sure). For each participant a mean of the 3 items was calculated. Scores range from 1-5 with higher scores indicating higher levels of self-efficacy.

This subscale includes three items (e.g., "Imagine that you met someone at a party. He or she wants to have sex with you. Even though you are very attracted to each other, you're not ready to have sex. How sure are you that you could keep from having sex") rated on a scale ranging from 1 (not sure at all) to 5 (extremely sure). A mean score for the three items was calculated for each participant with score ranging from 1-5. Higher scores indicating higher levels of self-efficacy for refusing sex.

Self-efficacy for communication was assessed using the SECM subscale of the SRBBS. This subscale includes three items (e.g., "Imagine that you and your partner have been having sex but have not used condoms. You really want to start using condoms. How sure are you that you could tell that person that you want to use condoms") rated on a scale ranging from 1 (not sure at all) to 5 (extremely sure). A mean score for the three items was calculated for each participant with score ranging from 1-5. Higher scores indicating higher levels of communication.

Self-Efficacy for using PrEP was assessed with a 4 item survey. Each item was measured on a scale ranging from 1 (strongly disagree) to 5 (strongly agree). A mean score for the three items was calculated for each participant with score ranging from 1-5. Higher scores indicating higher levels of self-efficacy.

Attitudes about condom use were assessed using the ACU subscale of the SRBBS. This subscale includes three items scored from -2 (strongly disagree) to +2 (strongly agree). A mean score was calculated for each participant with negative mean scores indicating negative (unhealthy) attitudes about condom use and positive scores indicating positive (healthy) attitudes about condom use.

Attitudes about sexual intercourse were assessed using the ASI subscale of the SRBBS. This subscale includes three items scored from -2 (strongly disagree) to +2 (strongly agree). A mean score was calculated for each participant with negative mean scores indicating negative (unhealthy) attitudes about condom use and positive scores indicating positive (healthy) attitudes about sexual intercourse.

Intentions were measured with one item ("I intend to find a clinic in my community where I can speak to a doctor or health care provider about PrEP"). A mean score for the three items was calculated for each participant with score ranging from 1-5. Higher scores indicating stronger intentions.

STI/HIV knowledge was assessed using 12 questions for which participants could answer "true", "false", or "not sure". The answers were recoded as correct or incorrect, with "not sure" being coded as incorrect, and a sum was calculated for each participant. Scores range from 0 - 12 with higher scores indicating more STI-HIV knowledge.

Norms about condom use were assessed using the NCU subscale of the SRBBS. This subscale includes three items scored from -2 (strongly disagree) to +2 (strongly agree). A mean score was calculated for each participant with negative mean scores indicating negative (unhealthy) perceived about condom use and positive scores indicating positive (healthy) perceived norms about sexual intercourse.

Norms about sexual intercourse were assessed using the NSI subscale of the SRBBS. This subscale includes three items scored from -2 (strongly disagree) to +2 (strongly agree). A mean score was calculated for each participant with negative mean scores indicating negative (unhealthy) perceived about condom use and positive scores indicating positive (healthy) perceived norms about sexual intercourse.

Perceived norms about the use of PrEP were assessed using a 2 item survey. Both items were rated from 1 (not at all) to 4 (a lot). A mean of the two items was calculated for each participant with score ranging from 1-4. Higher scores indicate more positive perceived norms about the use of PrEP.

The BCU subscale includes six items assessed on a scale ranging from 1 (strongly disagree) to 5 (strongly agree). A mean score was calculated for each participant with score ranging from 1-5. Higher scores indicating more perceived barriers to condom use.

Acceptability of the intervention condition is assessed via self-reported survey at the post gameplay time point using the game experience and satisfaction questionnaire, which is a 10-item scale with 4-point Likert-type responses ranging from 1 (strongly disagree) to 4 (strongly agree). Total score range 10-40. Data were collected from participants in the experimental group only. Higher scores indicate stronger agreement with the statement.
