Friendship Bench Adaptation to Improve Mental Health & HIV Care Engagement Outcomes Among PLWH and PWID in Vietnam (VITAL)

Friendship Bench Adaptation to Improve Mental Health & HIV Care Engagement Outcomes Among PLWH and PWID in Vietnam

Adaptation of the Friendship Bench Counseling Intervention to Improve Mental Health and HIV Care Engagement Outcomes Among People Living With HIV Who Inject Drugs in Vietnam

This project will adapt and pilot a feasible and effective problem-solving therapy designed for low-resource settings to address common mental disorders like depression and anxiety - the Friendship Bench- in a Vietnamese population of individuals living with HIV who also have opiate use disorder. The Friendship Bench approach has the potential to make an important contribution to address CMDs and reduce barriers to HIV treatment success among people living with HIV (PLWH) with Opioid Use Disorder (OUD), a critical population driving the HIV epidemic in Vietnam and many Southeast Asian countries. This proposal will generate critical evidence for designing a fully powered clinical trial to test the investigation team's adapted FB protocol in improving HIV, mental health, and drug use treatment outcomes for this vulnerable population.

Injection drug use is the primary driver of the HIV epidemic in Southeast Asia. In 2017, the HIV prevalence among people who inject drugs (PWID) in Southeast Asia was 15%. PWID, most of whom have OUD, who are living with HIV have low rates of retention in care, antiretroviral therapy (ART) initiation, and viral suppression. PWID also experience high rates of HIV-related and all-cause mortality. Common mental disorders (CMDs), including depressive, anxiety, and stress-related illnesses, occur in 40-50% of PLWH and OUD. Despite serious consequences of mental illness on health and HIV progression, mental illness remains under-diagnosed and under-treated in HIV populations, especially in low- and middle-income countries (LMICs), such as many countries in Southeast Asia. To respond to the great need for mental health treatment in low- and middle-income countries, the global mental health field has focused on developing task-shifting and integration approaches that equip non-specialists to deliver evidence-based mental health interventions at scale. However, such task shifting interventions to address CMDs have received limited attention in Southeast Asia among OUD. Vietnam, with its high prevalence of PLWH and OUD, its integration of methadone maintenance therapy (MMT) with HIV care, and its priority for developing CMD care for this population, is an ideal setting to evaluate task-shifting mental health approaches to address CMDs and improve HIV care outcomes. The Friendship Bench (FB) is a feasible and effective task-shifting mental health intervention designed for low-resource settings that is a strong candidate to address CMDs in this population. FB is a problem solving therapy-based intervention with demonstrated effectiveness in treating CMDs among primary care patients when delivered by lay counselors. Lay counselors may effectively deliver FB to PLWH with OUD, but CMD may prove more difficult to treat in patients with OUD and require professionally trained counselors to be effective. The investigators' objective is to complete a pilot randomized trial of 75 patients from 4 MMT clinics in Hanoi. The investigators' specific aims are: 1) To adapt the Friendship Bench (FB) protocol to be optimized for PLWH and OUD in Vietnam; and 2) To evaluate the feasibility, fidelity, and acceptability of the adapted FB as well as preliminary indicators of its impact in improving CMDs and HIV care and drug use treatment outcomes. The Friendship Bench approach has the potential to make an important contribution to address CMDs and reduce barriers to HIV treatment success among PLWH with OUD, a critical population driving the HIV epidemic in Vietnam and many Southeast Asian countries. This proposal will generate critical evidence for designing a fully powered clinical trial to test the adapted FB protocol in improving HIV, mental health, and drug use treatment outcomes for this vulnerable population.

25 participants seeking HIV and/or MMT services at participating clinics in Hanoi, Vietnam will be enrolled in this study arm during study recruitment. Individuals enrolled in this arm will initiate FB with a professional counselor. Individuals enrolled in this arm will receive 6 weekly counseling sessions per the adapted FB protocol (Aim 1).

25 participants seeking HIV and/or MMT services at participating clinics in Hanoi, Vietnam will be enrolled in this study arm during study recruitment. Individuals enrolled in this arm will initiate FB with a trained lay counselor. Individuals enrolled in this arm arm will receive 6 weekly counselling sessions per the adapted FB protocol (Aim 1).

25 participants seeking HIV and/or MMT services at participating clinics in Hanoi, Vietnam will be enrolled in this study arm during study recruitment. Enhanced usual care will include general training of the HIV providers and clinics about CMD identification and management, and feedback to the HIV provider of the status of their enrolled patient to allow follow-up per the clinic's standard care.

Participants randomized to this arm will receive the Friendship Bench protocol delivered by a professional counselor.

Participants randomized to this arm will receive the Friendship Bench protocol delivered by a trained lay counselor.

Enhanced usual care (EUC) will include general training of the HIV providers and clinics about CMD identification and management, and feedback to the HIV provider of the status of their enrolled patient to allow follow-up per the clinic's standard care. Information will be collected in follow-up interviews to characterize the care that patients receive. These activities will occur in all three arms, but they are the only activities in the EUC arm.

This measure of feasibility will be measured as the ability to successfully enroll PLWH and OUD with CMDs in the pilot intervention. Feasibility will be evaluated by measuring the recruitment rate (number of patients approached in order to accrue the final sample).

This measure of feasibility will be measured as the ability to retain PLWH and OUD with CMDs in the pilot trial. Feasibility will be evaluated by measuring the number of participants retained in the study (number of patients enrolled at baseline who are still enrolled in the trial), through study completion.

The number of FB sessions attended by participants out of total FB sessions offered, during the target intervention duration of 6 weeks.

The number of patients who were either very satisfied or somewhat satisfied with the FB among all participants who received the FB. Satisfaction will be measured on a 4-point Likert scale-- 1 indicates high satisfaction and 4 indicates high dissatisfaction.

The total number of FB sessions meeting or exceeding for at least 75% of the total number of fidelity checklist items assessed per session.

HIV viral load will be measured from clinical records, or measured and ordered by the study if no viral load is collected in the appropriate window.

The proportion of scheduled visits in the 12-month follow-up period that are attended vs. no-shows (the "kept visit proportion"), with no-show defined as no appointment kept in the 30 days following a scheduled appointment. HIV appointment data will be abstracted from clinic records at the end of the study period.

CMD symptoms will be evaluated via the 21-item Depression, Anxiety, and Stress Scale (DASS-21), which consists of three subscales. Responses are ranked from 0 (Does not apply to me at all) to 3 (Applied to me very much or most of the time). All subscales are multiplied by 2. The total scale is calculated by summing the subscales, range 0-126, for depression (threshold ≥14), anxiety (threshold ≥10), and stress (threshold ≥19); higher scores indicate higher severity of symptoms.

Depression symptoms will be evaluated via the 21-item Depression, Anxiety, and Stress Scale (DASS-21), which consists of three subscales. Responses are ranked from 0 (Does not apply to me at all) to 3 (Applied to me very much or most of the time). All subscales are multiplied by 2. Scores ≥ 14 on the depression subscale indicate a depressive disorder.

The absolute reduction of depressive symptoms from baseline to 6 weeks will be evaluated via the DASS-21 depression subscale.

Anxiety symptoms will be evaluated via the 21-item Depression, Anxiety, and Stress Scale (DASS-21), which consists of three subscales. Responses are ranked from 0 (Does not apply to me at all) to 3 (Applied to me very much or most of the time). All subscales are multiplied by 2. Scores ≥ 10 on the anxiety subscale indicate an anxiety disorder

The absolute reduction of anxiety symptoms from baseline to 6 weeks will be evaluated via the DASS-21 anxiety subscale.

Stress symptoms will be evaluated via the 21-item Depression, Anxiety, and Stress Scale (DASS-21), which consists of three subscales. Responses are ranked from 0 (Does not apply to me at all) to 3 (Applied to me very much or most of the time). All subscales are multiplied by 2. Scores ≥ 19 on the stress subscale indicate a stress disorder.

The absolute reduction of stress symptoms from baseline to 6 weeks will be evaluated via the DASS-21 stress scale.

Out of the first 365 days of study participation, the total number of days a participant took their MMT dose divided by 365 days.
