The Health Belief Model (HBM) will guide the content and delivery of the pharmacist-led educational intervention. The intervention will address six core HBM constructs: perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy. The purpose of applying the HBM is to improve patients' understanding of chronic obstructive pulmonary disease (COPD) and promote positive behavioural changes, particularly improved medication adherence.
