Brief Summary

This couples-based, digital health intervention project is serostatus neutral and seeks to determine efficacy for: a) use and adherence to evidence-based HIV/STI prevention-care strategies; b) creation and adherence to a tailored prevention-care plan; c) creation and adherence to a tailored sexual agreement; and d) improvements in other relationship dynamics among male couples who are in a relationship (defined as greater than 3 months or more).

Outcome Measures

Primary Outcomes (12)

  • Change in HIV incidence by comparing results from test kits received at baseline to 16-months.

    Participants will be asked to provide sample to test for HIV at baseline and 16-months, using at-home self-collection test kits. Count: New HIV and STI diagnosis via biomedical testing at follow-up occurring 16 months after baseline randomization.

    Baseline to 16-months

  • Change in STI incidence by comparing results from test kits received at baseline to 16-months.

    Participants will be asked to provide samples to test for STIs at baseline and 16-months, using at-home self-collection test kits. Count: New HIV and STI diagnosis via biomedical testing at follow-up occurring 16 months after baseline randomization.

    Baseline to 16-months

  • Changes in relationship communication patterns by comparing responses from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

    Participants will be asked 11 questions with Likert-type scale responses (range 1-9) at all time points: 3 items for mutual constructive communication (MCC): higher scores represent greater MCC. 8 items for avoidance and withdrawal patterns (AW): higher scores represent greater AW. Changes in mean scores of MCC and AW (individual, couple), respectively, will be evaluated from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

  • Changes in relationship commitment by comparing responses from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

Higher scores represent greater trust toward the partner in the relationship. Changes in mean scores (individual, couple) from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

  • Changes in relationship communal coping by comparing responses from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

    Participants will be asked 42 items (range 1-5): outcome efficacy to reduce HIV threat subscale of joint effort (7 items), communication (7 items), and planning and decision-making (7 items); couple efficacy reduce HIV threat subscale of joint effort (7 items), communication (7 items), and planning and decision-making (7 items). Higher scores represent greater attitudes to achieve outcomes or couple's confidence that together they can engage in communal coping efforts.

  • Changes in relationship transformation of motivation by comparing responses from baseline to 8-months, 8-months to 16-months, and baseline to 16-months.

    Participants will be asked about their relationship transformation of motivation (ToM) at all time points, using 2 questions (range 1-5). ToM measures (1) cognitive and (2) emotional response to the health threat. Higher scores represent greater cognitive response and emotional response, respectively.
