The use of regular inhaled therapy has shown to achieve such goals. However, patient’s belief is one of the factors affecting their treatment adherence. This study was carried out to determine the belief about regular inhaled therapy among COPD patients in Sibu Hospital. Materials and Methods Study Design: Cross-Sectional study Target population: Stable COPD patient Sampling method: Convenient sampling COPD specific Belief about Medicines Questionnaire. Validated questionnaire consists of 2 domains: 1.Necessity domain (7 questions, score range: 7-35): Assess patient’s belief on the necessity of their inhaled therapy. 2.Concern domain (15 questions, score range: 15-75): Assess patient’s concern on regular use of their inhaled therapy.
