Objective To develop the willingness to use tele-rehabilitation scale for patients with chronic obstructive pulmonary disease (COPD) and provide an assessment tool for evaluating the willingness to use tele-rehabilitation in COPD patients. Methods Based on the Unified Theory of Acceptance and Use of Technology (UTA-UT) and the Health Belief Model (HBM), the initial items of the scale were formed by literature review and Delphi technique.A questionnaire survey was conducted in 156 patients with COPD using convenience sampling method. Item analysis,reliability testing, and validity testing were performed on the scale. Results The positive coefficients of both rounds of expert inquiries were 100%; the expert authority coefficients were 0.872 and 0.888 respectively; the Kendall′s coordination coefficients were 0.114 and 0.113 respectively （all P＜0.05）; the coefficients of variation ranged from 0.08 to 0.23 and from 0.05 to 0.22, respectively.There were a total of 26 items in the formal scale, with 7 common factors extracted through exploratory factor analysis resulting in a cumulative variance contribution rate of 84.84%. At the item level, the content validity index ranged from 0.800 to 1.000, while at the scale level it was 0.913.The Cronbach′s α coefficient for the entire scale was found to be 0.963.The split-half reliability was 0.884. Conclusion The willingness to use tele-rehabilitation scale for patients with COPD exhibits good reliability and validity, and can be used as an assessment tool for such patients.
