About this study

The study will test the feasibility and acceptability of using text messages and behavioral economics-based incentives to support anchoring Anti-Retroviral Therapy (ART) adherence to an existing routine in order to improve long-term ART medication adherence. The intervention phase of the three-phased study will constitute the pilot RCT. A sample of 150 clients who have initiated ART in the preceding three months will be randomized to either usual care (C = 50) or one of the two INMIND intervention groups (daily text message reminders with or without incentives) for three months (T1 = 50; T2=50). Subsequently, behavioral persistence will be evaluated for six months post-intervention. Assessments will be conducted at baseline, month 3, and month 9. The primary outcomes are 1) electronically measured mean medication adherence during the intervention and 2) six months post intervention, along with 3) timeliness of medication adherence during the intervention and 4) six months post-intervention.

Read the detailed description

Adherence of Anti-Retroviral Therapy (ART) among HIV-infected patients initiating treatment (treatment initiators) in Sub-Saharan Africa has remained low, even though the number of treatment initiators has increased in recent years. Lack of retention in care and low adherence in the first year of ART treatment are substantial barriers to virologic suppression. The current R34 study tests a novel approach for improving long-term ART adherence among treatment initiators by turning adherence into a behavioral routine. This is done in two ways: 1) anchoring ART adherence to an existing routine, and 2) providing more immediate rewards and increasing the salience through reminder messages. Insights from behavioral economics suggest that such an intervention may be particularly effective for people with present bias (those who have a tendency to give in to short-term temptation at the cost of more long-term benefits) and lack of salience (where over time, the choice of target behavior is overshadowed by more pressing needs of daily life) which have been found to be prevalent among people living with chronic medical conditions from past studies.

The intervention will be tested through a pilot RCT, wherein 150 adult clients will be randomly assigned to three groups. The first intervention group would receive daily text messages that reinforce routine formation information provided to all participants (across the three groups). The second intervention group will receive the text messages, and additionally be eligible for a prize drawing based on timely ART adherence, at each monthly clinic visit. The control group will receive care as usual, consisting of routine formation information as well as adherence counseling. The intervention will last three months, with a six-month post-intervention follow up period. All participants will receive MEMS caps to record adherence, and will complete assessments over nine months (baseline, post-intervention, and six months post-intervention).

The Specific Aim of the intervention phase of the study is to test the preliminary effectiveness of the intervention, including the relative effectiveness of the two different implementation approaches. This is preceded by the formative phase, with the Specific Aim of developing the intervention parameters. The intervention phase is succeeded by the adaptation phase, whose Specific Aim is to collect data in preparation for a subsequent R01 application.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Daily Text MessagesBehavioural

    Participants will receive daily text message reminders to use their routine behavior to trigger medication adherence.

  • Incentivization based on timely ART adherenceBehavioural

    Participants will be eligible to draw a prize if they take their medication within +/- one hour of the stated existing routine to which pill-taking is anchored on at least 70% of days between recruitment and the 3-month study visit.

Study groups in NCT05131165
Study groupRoleWhat they receive
ControlNo interventionThis arm will receive care as usual, including the adherence support mechanisms that are part of usual care practices. At recruitment participant will be explained the importance of pill-taking. All participants (including in the control group) will receive a leaflet containing detailed information on how to establish healthy pill-taking routines. Finally, clinic staff will counsel participants on how to select an already regularly routine behavior that occurs at roughly the same time each day that forms the basis of their implementation plan.
Intervention group receiving messages (Messages Group)ExperimentalParticipants will receive the same information as those in the Control Group, but in addition, receive the "Daily Text Message" Intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of Pills Taken as Prescribed Over the Intervention Period (Baseline - Month 3)

    MEMS-data was collected continuously over the course of the three-month intervention period allowing us to investigate mean adherence. Only one of the ART medications was used to calculate the primary adherence variable (# of actual bottle openings / # of prescribed bottle openings).

    Measured: Three months

  2. Proportion of Pills Taken as Prescribed Over the Post-intervention Period (Months 4-9)

    MEMS-data was collected continuously over the course of the six-month post intervention period allowing for the investigation of post-intervention mean adherence. Only one of the ART medications was used to calculate the primary adherence variable (# of actual bottle openings / # of prescribed bottle openings).

    Measured: Six months post-intervention

  3. Proportion of Pills Taken Within +/- 1 Hour of the Anchor Time Over the Intervention Period (Baseline - Month 3)

    A novel measure of routine adherence (that it is explicitly based on the temporal pattern of pill-taking), calculated as the fraction of scheduled pills taken within a one-hour window around the typical time that participants report completing their existing routine behavior that anchors their pill-taking, was calculated. This measure provides an objective way for determining behavioral automaticity of pill-taking.

    Measured: Three months

  4. Proportion of Pills Taken Within +/- 1 Hour of the Anchor Time Over the Post-Intervention Period (Months 4-9)

    This measure would be calculated as a fraction of scheduled pills taken within a one-hour window around the typical time that participants report completing their existing routine behavior that anchors their pill-taking, for all visits made post-intervention.

    Measured: Six months post-intervention

Secondary outcomes (2)
  1. Retention in Care

    Retention in care was measured as the fraction of participants recruited who are still active clients at the clinic at month 9.

    Measured: Month 9

  2. Change in Viral Suppression Status

    HIV RNA (viral load) was the secondary outcome measure. For each participant, viral loads taken just prior to baseline and viral loads taken just after month-9 were compared; if participant was virally suppressed (with < 200 copies of HIV per millilitre (mL) of blood) at baseline, but had a viral load of >= 200 copies/mL after month-9, then the indicator was assigned "-1"; if there was no change in viral suppression status (i.e., if participant either had >= 200 copies of virus/mL at baseline and month-9 OR if participant had < 200 copies/mL at baseline and month-9), then the indicator was assigned "0". If, however, the participant's viral load went from >= 200 copies/mL at baseline to < 200 copies/mL after month-9, then the indicator was assigned "1".

    Measured: Month 9

Individual data sharing
Yes: Data collected in the execution of the aims described in the application will be shared in the form of journal publications. Following publication of the main paper(s) for this study and the grant end-date, the RAND Human Subjects Protection Committee will be consulted about how to securely make data publicly available in the form of an electronic database for researchers who successfully complete a registration process (described below). Any shared data will be de-identified and will not contain any direct identifiers or indirect identifiers (that could identify participants by inference). No qualitative data will be shared, as such data would be difficult to de-identify given that participants will be telling their own experiences and thus could be identified by inference. Documentation of shared data will be provided in the form of a codebook in which each variable name and response options are defined.
