Study Overview
Brief Summary
This is a multi-center pilot study to examine the effectiveness of a health literacy-based intervention to improve medication adherence and self-efficacy of medication use among individuals with coronary heart disease (CHD). The specific aims are to: i) develop a health literacy-based intervention to improve medication adherence for CHD individuals with low health literacy and ii) evaluate the effects of a health literacy-based intervention on improving medication adherence and self-efficacy in CHD individuals.
Detailed Description
The project will be conducted in 2 phases. Phase 1 is to develop the health literacy-based intervention that consists of a video and an education booklet. Phase 2 is to conduct a pilot study to evaluate the effectiveness of the intervention. A total of 60 participants with low health literacy and diagnosed with CHD will be recruited in two settings. Data will be collected at baseline and 4-weeks after enrollment. The following data will be collected:
At baseline: Socio-demographic information (e.g. age, gender, education level, income, past medical history, social support), health literacy (eligibility screening at time of recruitment), CHD knowledge, medication adherence, and medication self-efficacy.
4-weeks after enrollment: medication self-efficacy and medication adherence.

Arms & Interventions
Intervention group
At baseline: video and education booklet. 2-weeks after enrollment: telephone call by nurse.
Intervention: Health literacy-based intervention (Behavioral)
Control group
Usual care
Outcomes
Primary Outcomes
Change from baseline medication adherence at 4-weeks follow-up
Time Frame: Baseline and 4-weeks follow-up
Measured using the Chinese version of the Hill-Bone Medication Adherence Scale (HB-MAS). The HB-MAS is a self-reported measure of the extent of medication adherence. The HB-MAS consists of 9 questions with each item rated on a 4-point scale (1 = none of the time; 2 = some of the time; 3 = most of the time; and 4 = all of the time). The total score ranges from 9 (minimum) to 36 (maximum), where lower scores indicate higher levels of medication adherence.
Secondary Outcomes
- Change from baseline medication self-efficacy at 4-weeks follow-up(Baseline and 4-weeks follow-up)
