With a full-scale randomized control trial, the investigators will evaluate the efficacy and cost effectiveness of Mlambe, an economic and relationship-strengthening intervention that provides incentivized saving accounts, financial literacy training, and relationship skills education to break the cycle of poverty around drinking, strengthen couple support and communication, and reduce heavy drinking among HIV-affected married couples with a partner who drinks alcohol in Malawi.

The inter-related issues of alcohol use, intimate partner violence (IPV), and economic insecurity threaten to derail progress towards UNAIDS 95-95-95 targets in sub-Saharan Africa (SSA). Rates of heavy drinking are alarmingly high among people living with HIV (PLWH), and almost twice that of the general population. Heavy drinking is very common in Malawi, and has deleterious effects on antiretroviral therapy (ART) adherence and HIV clinical outcomes, but also indirectly affects health by damaging the couple relationships needed for social support, economic survival, and well-being. Most alcohol interventions treat heavy drinking as an individual-level issue; however, for people in committed relationships, research suggests an urgent need for interventions that consider alcohol use as a couple-level issue involving both partners. Novel alcohol interventions are paramount for breaking cycles of IPV and poverty, and creating stronger families to prevent HIV, and reduce HIV mortality, morbidity, and transmission. Yet, no interventions to date have jointly addressed the economic and relationship context of drinking alcohol among people living with HIV in SSA, which may have synergistic effects on heavy alcohol use when combined.

To address this gap, the investigators developed and tested Mlambe, an economic and relationship-strengthening intervention that provides incentivized saving accounts, financial literacy training, and relationship skills education to break the cycle of poverty around drinking, strengthen couple support and communication, and reduce heavy drinking. Pilot results showed that Mlambe was feasible and acceptable, and showed promise of efficacy. Given this strong evidence, the investigators will evaluate the efficacy and cost-effectiveness of Mlambe with a full-scale RCT. This is the first RCT of an integrated economic and relationship-strengthening intervention to address alcohol use in HIV-affected couples.

For Aim 1, the primary hypothesis is that the odds of heavy alcohol use will be lower in Mlambe as compared to enhanced usual care (EUC). Secondarily, the investigators expect that Mlambe participants will have a higher odds of ART and appointment adherence, and viral suppression, and lower number of drinking days, AUDIT-C score, and PEth levels. For Aim 2, the investigators hypothesize that Mlambe participants will report greater improvements in relationship dynamics (e.g., better communication, less IPV) as compared to EUC participants.

Inclusion Criteria:

1. In a married or cohabitating union
2. Have at least one partner with a positive AUDIT-C screen in prior 3 months
3. Must also currently be on ART for at least 6 months
4. Must have disclosed their HIV status to their partner

Exclusion Criteria:

1) Severe intimate partner violence reported in previous 3 months and/or fear that safety would be at risk by participation in the study (reported at screening). Couples who participated in Mlambe's pilot study will also be excluded.

The dataset will include self-reported demographic and behavioral data from surveys and laboratory data from blood specimens. Individual-participant level or IPD data will be shared. The data will be made in a de-identified format. In addition to the IPD dataset, the researcher will share the data dictionary and final protocol with amendments.

Identifiable data will be de-identified prior to repository submission. All participant-level data will be preserved and shared through deposition in the National Institute on Alcohol Abuse and Alcoholism (NIAAA) sponsored data repository, the NIAAA Data Archive (NIAAADA), a controlled access public repository. The NIAAADA is housed within the NIMH Data Archive (NDA).

All collection data will be shared automatically two years after the grant end date specified on the first Notice of Award. Any subject-level data and the associated analyzed data used in a journal publication will be shared at the time of publication, even if the publication occurs before the two-year automatic share date.

The data will be made available for sharing with the general research community via the NIAAA website. Investigators at institutions with a Federal Wide Assurance (FWA) will be able to gain access to NIAAADA data by submitting a data access request in accordance with applicable NIAAADA policies. Data requests will be reviewed and granted by an NDA Data Access Committee. NDA will make decisions about how long to preserve the data, but that data archive has not deleted any deposited data up to now.
