We assessed the reliability of the Baltimore Activity Scale for Intermittent Claudication (BASIC) for the evaluation of physical activity levels in individuals with intermittent claudication. We also identify the characteristics of the patients that influence the reliability of this questionnaire. A total of 38 men and women with peripheral artery disease and symptoms of intermittent claudication participated in the study. BASIC was administered to patients by the same evaluator at 2 different visits, separated by 7 days. The concordance coefficient ranged from .43 (How often do you walk at a fast pace?) to .85 (What happens when you feel pain while you walk?). The concordance coefficient of BASIC total score was .60. Higher concordance coefficients were observed in women (.66 vs .55), in younger patients (.63 vs .56), and in patients with lower ankle–brachial index (.64 vs .55). The reliability of BASIC questionnaire ranged from moderate to good in patients with claudication.
