Validity and reliability of Baecke questionnaire in physical activities measurement are assessed in both healthy and ill subjects (10,13,21,26,27).
The Baecke questionnaire, however, is a useful instrument which can assess a person's long period of physical activities (the previous year) and can be used for both healthy and ill people.
The Baecke questionnaire is a tool that evaluates individual's habitual physical activities over the previous 12 months.
Initially, based on the standardized cross-cultural translation guidelines project (30), the English version of the Baecke questionnaire was translated into Persian.
For the purpose of validation, the Persian version of the Baecke questionnaire was administered to 126 healthy subjects.
As shown in Table 2, the Persian version of Baecke questionnaire enjoys sound reliability indices in test-retest measurements (ICC > 0.7).
