Background Physical activity questionnaires assess functional capacity in cardiovascular patients, yet none are specifically developed for second phase cardiac surgery rehabilitation. This study aimed to develop and validate a physical activity questionnaire for patients during the first three months following cardiac surgery. Methods A cross-sectional study was conducted with 94 post-cardiac surgery patients within three months after the surgery. In Phase 1, a physical activity questionnaire was developed for these patients, and later, its content validity was examined, and its reliability was determined. In Phase 2 of the study, the validity of the questionnaire was tested by evaluating its correlation with the 6-minute walk distance (6MWD), the scores from the Duke Activity Status Index (DASI), and the dimension-specific scores of the SF-36 quality of life questionnaire. Results A physical activity questionnaire for post-cardiac surgery patients was developed with 27 items. The Index of Item-ObjectiveCongruence (IOC) showed an average value of 0.91, and the reliability measured by Cronbach's alpha was 0.88. Regarding the validity, the scores from the questionnaire showed a significant correlation with the 6MWD (r s = 0.58), the scores from the DASI (r s = 0.69), and with the physical functioning dimension of the SF-36 questionnaire (r s = 0.40). Conclusion The physical activity questionnaire demonstrated the validity and reliability to assess the functional capacities of post-cardiac surgery patients, as well as correlation with other standardized physical activity questionnaires.
