Measure
Transition Theory-based Intervention
Participants in the intervention arm will receive the Transition Theory-based intervention consisting of 4 sessions with a community health worker (2 during pregnancy, 2 postpartum) to support their transition from pregnancy to postpartum. Transition Theory-based Intervention: The behavioral intervention is a theoretically driven curriculum focused on supporting mothers from pregnancy through postpartum in order to promote sustained HIV treatment adherence. Sessions utilize motivational interviewing and consist of a range of topics including motherhood, preparing for baby, disclosure, HIV education, adherence, birth experiences, support systems, and living positively.
Enhanced Standard of Care Control
Participants in the control arm will receive the standard of care plus one session with a community health worker. Enhanced Standard of Care Control: In addition to standard of care, participants receive the first session of the Transition Theory-based Intervention curriculum which focuses on motherhood and preparation for baby but does not discuss the transition from pregnancy to postpartum or the postpartum period.

PRIMARY outcome

Timeframe: 3 months postpartum

Population: Transition Theory-based intervention participants received 4 counseling sessions compared to 1 session for those in the enhanced standard of care control condition; means are reported based on these denominators and should not be compared by condition

Feasibility will be assessed through the number of counseling sessions completed.

PRIMARY outcome

Timeframe: 6 months postpartum

Population: There was substantial LTFU for the 6 month postpartum timepoints. Analyses are conducted with all participants for whom these assessments were collected.

Preliminary efficacy will be assessed as the correlation between study arm and self-reported HIV adherence on the 3 item Wilson ART adherence scale (self-report, 3 item scale recoded as 0-100, 100 indicating perfect adherence in the past month) at 6 months postpartum.

PRIMARY outcome

Timeframe: 6 months postpartum

Preliminary efficacy will be assessed as the correlation between study arm and retention in HIV services at 6 months postpartum. Retention in HIV services is measured by clinic records. Retention at 6 months postpartum is measured as attended HIV clinic appointment in the past 3 months.
