HIV Infections | Behavioral: myDEx Behavioral: NTHP | Not Applicable |
A resurgence of new HIV cases among young men who have sex with men (YMSM; ages 18--24) has underscored the importance of developing culturally- and developmentally- informed HIV programs for YMSM. The investigators are developing and pilot testing a tailored, web- based intervention called myDEx that focuses on delivering HIV prevention messages based on single YMSM's relationship expectations and partner--seeking behaviors. To maximize intervention appeal and appropriateness, the investigators have convened a youth advisory board (YAB) to provide insight and feedback during the 3--stage intervention development process. Using an iterative design and development process, they have developed tailored messages that align YMSM's relationship experiences and desires with HIV prevention strategies. The investigators designed and developed the myDEx tailored online prevention intervention, as well as an attention- control non--tailored HIV/AIDS prevention (NTHP) comparison intervention. After developing both interventions, the investigators used usability testing procedures to collect preliminary data from 16 YMSM on the proposed intervention's design and acceptability. Recommended changes were added to the intervention prior to launching a small pilot randomized controlled trial (RCT). The pilot RCT will compare myDEx (N=120) to NTHP (N=60) to assess intervention feasibility and acceptability, and gather preliminary behavioral data to inform a subsequent application. Assessments will be collected at 30, 60, and 90 days follow--up.
Specific Aims include:
- To develop a tailored (myDEx) and non-tailored (NTHP) HIV prevention intervention focused on addressing HIV risk behaviors among single YMSM;
- To collect preliminary data on the feasibility, acceptability, and intervention content of the myDEx (N=16) in preparation for a small pilot RCT; and,
- To implement a small pilot RCT of the refined myDEx (N=120) as compared to the NTHP (N=60) intervention, in order to evaluate its feasibility and acceptability and gather preliminary efficacy results in reducing sexual risk behaviors.

Experimental: myDEx Intervention
The proposed intervention will consist of a 6-session web-based program. Cognizant of challenges maintaining users' attention in a web application and to facilitate delivery through a smartphone, the investigators will design each session to be no more than 20 minutes in length. In the course of these 6 sessions, YMSM will have a total of 120 minutes of intervention exposure. Across sessions, the investigators will emphasize the importance of sexual decision-making across different partner types, help YMSM consider what type of relationship(s) they want, and align these relationship desires with safer sex practices.

Active Comparator: Non-tailored HIV Prevention
The investigators will create a 6-session web-based attention-control comparison to match myDEx in time and attention yet have non-tailored and non-interactive content (NTHP). NTHP will include HIV/STI information currently available on sex education websites.

Behavioral: NTHP
The investigators will create a 6-session attention-control comparison to match the intervention in time and attention yet have non-tailored and non-interactive content (NTHP). NTHP will include HIV/STI information currently available on sex education websites. The attention-control condition allows the investigators to avoid confounding due to content and ensures that all participants receive some HIV prevention content given their high vulnerability to HIV. Further, this comparison will help critically examine the extent to which tailoring increases the acceptability to the program, above and beyond having a non-tailored, non-interactive intervention. |
- Number of Participants With Change in Number of Risky Sexual Partnerships [ Time Frame: Count of participants from baseline to 90-day follow-up reported ]The investigators estimated the change in the total number of participants who reported engaging in condomless anal intercourse from baseline to 90-day follow-up.
- Number of Participants With Change in HIV Testing Behavior [ Time Frame: Count of participants from baseline to 90-day follow-up reported ]The investigators estimated the number of participants who reported testing for HIV from baseline to 90-day follow-up.
- Change in Self-efficacy Motivations to Engage in HIV Prevention Behaviors [ Time Frame: Baseline to 90-day follow-up period ]The investigators will measure the change in safer sex self-efficacy over time using the HIV Risk Behavior Self-Efficacy Scale by Fisher, Fisher, Misovich, Kimble & Malloy (1996). The scale is measured on a 4-point scale (range 1-4), where higher scores mean less self-efficacy to negotiate safer sex with partners met online.
- Changes in Psychological Well-being [ Time Frame: Baseline to 90-day follow-up period ]The investigators will measure symptoms of depression and anxiety using the Brief Symptom Inventory by Derogatis & Spencer (1982). Higher mean scores (scale 1-4) indicate greater symptoms of psychological distress.
