BACKGROUND: The COVID-19 pandemic has led to innumerable challenges in the practice of physical therapy (PT) in both local and global settings. Healthcare settings often use Personal Protective Equipment (PPE) to prevent contamination. Despite its benefits, compliance is challenged by issues such as discomfort, availability, accessibility, and individual perception. OBJECTIVES: Considering the contrasting roles and nature of healthcare practitioners' work and the differences in the demands of PPE usage, this study aims to develop a profession-specific questionnaire on the perceptions of physical therapists on PPE usage in response to the COVID-19 pandemic with good face and content validity. METHODS: The study comprises Phase 1 for questionnaire development and Phase 2 for questionnaire validation. Five experts recruited using purposive sampling participated in three rounds of the validation process. Each expert evaluated the face and content validity through Google Forms. Consequently, an expert panel evaluation to reach a consensus on the final items. Google sheets were utilized for analysis. EXPECTED RESULTS The final questionnaire will have 35 items covering the Health Belief Theory domains. All items will receive FVI (overall agreement scores), I-CVI, S-CVI/Ave, and S-CVI/UA scores that meet the cut-off. The final questionnaire will be useful in evaluating physical therapists' perceptions of using PPE due to COVID-19 and may also be helpful to organizations, policymakers, and other entities in their decision-making for PPE protocols, guidelines, and implementation. Future researchers can use this study to conduct a pilot study that assesses other psychometric properties of the tool.
