Mi Propio Camino Intervention RCT for Blood Pressure Medication Adherence

The study is a randomized controlled trial (RCT) consisting of a 4-session educational intervention (completed over the course of 4-8 weeks) and a 6-month follow-up period for adherence monitoring. Participants will be allocated to one of two educational intervention groups following a block randomization schedule, stratified on the hypothesized mediator variable of medication-related beliefs (high versus low scores on the BMQ Necessity-Concerns subscore) to ensure the groups are balanced on this variable. Primary endpoint is medication adherence at 6 month follow-up, defined as the proportion of days that the prescribed number of doses was taken by the patient during a 30-day period, measured by a pill bottle cap monitor (medication events monitoring device \[MEMS\]).

Inclusion criteria are: (1) age 18 years or greater, (2) uncontrolled hypertension (BP above 140/90 mmHg), (3) Hispanic ethnicity, (4) Spanish or English-speaking, (5) at least one office visit at the study clinic in prior 12 months. Exclusion criteria: Persons with stage 4 or 5 chronic kidney disease (CKD) will be excluded.
