Abstract

Purpose: Considering the role of physical activity on public health and the high prevalence of physical inactivity worldwide, determining physical activity barriers is critical and will be a road map for future planning. This study aimed to develop a comprehensive questionnaire to determine physical activity barriers.
Methods: By reviewing previous studies, the main domains of the questionnaire were established. A physical activity expert interviewed 20 individuals aged 18 to 65 years. The results were evaluated by an expert panel for a content validity index. Face validity, test-retest reliability, and internal consistency were established on 204 individuals.
Results: The content validity index in all items was within the acceptable range (>0.85). Face validity was appropriate, and the misunderstanding index was < 20% in all items. Test-retest reliability in the final questionnaire in all items based on Cohen’s kappa was > 0.20, indicating fair agreement. Internal consistency with Cronbach’s alpha of 0.63 was within the acceptable range.
Conclusion: The study revealed that the newly designed survey is valid, accurate, and reliable. The use of this comprehensive tool by policymakers would help them properly identify the perceived barriers, and thus perform better physical activity interventions as promotional health programs.
