Acceptability, Feasibility, and Preliminary Impact of a Web-based, HIV Prevention Toolkit With Cisgender Male Couples in Lima, Peru

This digital couples-based HIV/STI prevention intervention project will determine preliminary efficacy to improve uptake of evidence-based strategies and a tailored prevention plan among cisgender male couples who are in a relationship (defined as greater than 3 months or more).

About this study

The project draws on our strong findings from the preliminary work we conducted in Lima. The 3-year project will update and adapt an existing digital health couples-based HIV/STI prevention toolkit intervention that showed promise for reducing couples' HIV risk. The intervention is theoretically grounded in Couples Interdependence Theory for health behavior change. The project is a 6-month pilot randomized control trial with 60 at-risk male couples using a delayed, educational control condition of 3 months. Our Specific Aims are to: 1) Assess feasibility to retain 60 consented and eligible male couples in a 6-month pilot RCT through quantitative measurement of enrollment and retention/attrition rates, and by reason for attrition; 2) Describe acceptability of the adapted toolkit intervention using mixed methods23 from 3 data sources. At last follow-up, partners responses to the Health Information Usability Evaluation Scale24 and other survey items (e.g., 3 things liked best/least about the toolkit, features for improvement) will be captured, along with the additional details they will share about their experiences during the individual-level, qualitative exit interview; 3) Examine preliminary impact of the toolkit intervention on couples': a) formation and adherence to a tailored risk-reduction plan and agreement; b) relationship functioning (e.g., communication); c) use of/adherence to evidence-based HIV/STI prevention strategies; and d) HIV/STI incidence. Preliminary impact will be assessed via changes in couples' outcomes a-d over time between trial arms, and for all couples.

Treatment and study plan

Para ti, para mi, para nosotros (P3)

Behavioral

From day 1 to day 180 (i.e., entire 6-month duration, post baseline) of the pilot trial, participants randomized to the intervention arm will have access to use the five modules as directed. The P3 intervention includes modules focused on topics of: HIV/STI prevention, sexual agreements, communication/decision-making skills, strengthening relationships and creating goals, and physical activity.

Waitlist Control Para ti, para mi, para nosotros (P3)

Behavioral

From day 91 to day 180 (i.e., starting after 3-month assessment) of the pilot trial, participants randomized to the waitlist control condition will have access to use the five modules as directed. The P3 intervention includes modules focused on topics of: HIV/STI prevention, sexual agreements, communication/decision-making skills, strengthening relationships and creating goals, and physical activity.

Primary outcomes

  1. Changes in the creation of a detailed risk reduction plan by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months

    Participants will be asked if they created a detailed risk-reduction plan that contains evidence-based strategies with their partner at all time points, using a dichotomous measure containing yes/no responses.

    Changes in number of individuals and couples who create a detailed risk reduction plan from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

  2. Changes in the creation of a detailed agreement by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Participants will be asked if they created a detailed agreement with their partner at all time points, using a dichotomous measure containing yes/no responses.

    Changes in number of individuals and couples who create a detailed sexual agreement from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

  3. Changes in adherence to risk-reduction plan by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Participants will be asked whether they had adhered to their risk reduction plan at all time points.

    Changes to categorical responses (yes/no) at individual and couple levels from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

  4. Changes in adherence to agreement by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months

    Participants will be asked whether they had adhered to their agreement at all time points.

    Changes to categorical responses (yes/no) at individual and couple levels from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

  5. Changes in the number of evidence-based prevention strategies being used over time by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months

    Participants will be asked to select which evidence-based HIV/STI prevention strategies they are currently using at all time points.

    Changes to categorical responses (yes/no) at individual and couple levels from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

  6. Change in HIV incidence by comparing results from testing at baseline to 6-months.

    Time frame: baseline to 6 months

    Participants will be asked to provide sample to test for HIV at baseline and 6-months.

    Count: New HIV diagnosis via testing at follow-up occurring 6 months after baseline randomization.

  7. Change in STI incidence by comparing results from testing at baseline to 6-months.

    Time frame: baseline to 6 months

    Participants will be asked to provide sample to test for HIV at baseline and 6-months.

    Count: New STI diagnosis via testing at follow-up occurring 6 months after baseline randomization.

  8. Changes in relationship mutual constructive communication (MCC) patterns by comparing responses from baseline to 3-months, 3-months to 6-months, and baseline to 6-months.

    Time frame: baseline to 3-months, 3-months to 6-months, and baseline to 6-months

    Participants will be asked about their MCC patterns at all time points, using a validated theoretical measure containing 11 questions with Likert-type scale responses ranging from 1-9. Higher scores indicate more positive communication patterns.

    Changes in mean scores (individual, couple) will be evaluated from baseline to 3-months and 3-months to 6-months.
