Communicative Pathways Predicting Adherence in Type II Diabetic Patients

posted on 2020-07-27, 20:22 authored by Clinton L BrownClinton L Brown
The current study empirically tested four models of type II diabetic patient adherence, including wellness, screening, medication, and treatment adherence. Four mediators were proposed patient understanding, agreement, trust, and motivation were tested for each model. The current study is grounded in patient-centered communication, responding to Street’s (2013) call to model pathways between communication and patient health outcomes. Moreover, the study argues that adherence, for type II diabetic patients should be conceptualized as four distinct clusters of behavior (wellness, screening, medication, and treatment). A sample of (n=817) type II diabetes patients from the U.S. under the care of a medical provider and taking medication for their type II diabetes were surveyed. Findings from the present study indicate that the relationship between patient-centered communication and patient-health outcomes is mediated by proximal outcomes. The results contribute to our understanding or patient-centered communication, patient understanding, agreement, trust, and motivation, and adherence behaviors. Resulted indicated that while three of the four proposed hypotheses were supported, the most commonly studied type of adherence (medication), the relationship between patient-centered communication and medication adherence was not mediated. The current study ends with a discussion and implication of the findings as well as directions for future research
