Past Research

The objectives of this study were to:

1. Classify patients’ medication adherence behavior with oral diabetes medications based on their beliefs in medicines and illness perceptions, and
2. To describe the characteristics of the patients in each cluster based on psychosocial variables such as patient’ self-efficacy, clinical, and sociodemographic characteristics.

Based on Horne’s necessity-concerns framework and the Extended Self-Regulatory Model, this study used an exploratory technique, cluster analysis to cluster patients into groups based on their beliefs. Personalized interventions developed based on patient clusters may lead to improved adherence and health outcomes.

If patients are going to be able to make informed decisions on which pharmacy to visit based on publicly reported quality information, they need to understand what pharmacy quality means. It is important to align and prioritize efforts aimed at educating patients on pharmacy quality and the use of pharmacy quality rating reports.

The study aims of this UW ICTR funded grant were:

1. To design a peer-led educational-behavioral intervention to change patient beliefs, self-efficacy, and medication adherence in African Americans (AAs) with type 2 diabetes and
2. To pilot a component (i.e., 3 of 8 weekly sessions) of the educational-behavioral intervention and utilize patient feedback to examine the feasibility and acceptability of the intervention.

June 2016–June 2020

This project, funded by a 4-year NIH KL2 Career Development Award, aimed to culturally adapt an illness perception questionnaire that assesses African American/Black beliefs about type 2 diabetes.

Based on the self-regulatory model using an exploratory sequential mixed methods approach, we utilized focus groups, cognitive interviews, and survey administration to develop a valid and reliable tool useful in identifying modifiable illness beliefs among African Americans/Blacks.

This study set the stage for the development and testing of an intervention that modifies patient beliefs and improves medication adherence among African American/Blacks with type 2 diabetes.

This study aimed to determine if health literacy had a moderator effect on the relationship between beliefs in medicines and illness perceptions in regards to medication adherence.

For patients with limited health literacy, it was not known if simply improving patients’ belief in the need for the medication (often provided by pharmacists educating patients on medicines) may lead to improved medication adherence. This study helped to further investigate this question.

This research utilized the perspectives of patients with limited health literacy and the pharmacists who care for them to refine the prescription warning labels placed on medicine containers.
