简要总结
The purpose of this project is to study ways to make it more likely that patients will take their blood pressure medicine as recommended by their doctors.
详细描述
The objective of this randomized control trial is to evaluate, among 190 African-American patients with poorly controlled hypertension followed in a community-based primary care practice, whether motivational interviewing is more effective than usual care (routine counseling) in achieving adherence to prescribed blood pressure medications at 12 months.
The project aims to: 1) determine whether patients who receive motivational interview counseling have greater reduction in both systolic and diastolic blood pressure than those in the control group at 12 months. Clinic blood pressure readings will be assessed at baseline and at every three months thereafter for one year and 2) assess the effect of self-efficacy and intrinsic motivation as potential mediators of motivational interview on adherence. Self-efficacy and intrinsic motivation will be assessed at baseline and every three months thereafter for one year.

结局指标
主要结局
Score on Morisky Medication Adherence Scale (MMAS-4)
时间窗: Up to one year from baseline
Adherence to antihypertensive medications will be assessed at baseline and every three months thereafter for one year using a validated 4-item scale developed by Morisky that specifically addresses medication-taking. The scale asks patients to respond "yes" or "no" to a set of 4 questions. A positive response to any question indicates a problem with adherence. Each positive answer is assigned a score of 1. The total possible score is 4 with higher score indicating poorer adherence.
次要结局
- Blood pressure readings(Up to one year from baseline)
- Score on efficacy scale(Up to one year from baseline)
- Score on the Treatment Self-Regulation Questionnaire (TSRQ)(Up to one year from baseline)
