OBJECTIVE: The purpose of this study was to measure the reliability, internal consistency, construct validity, and floor and ceiling effects of the Brazilian version of the Self-Estimated Functional Inability because of Pain (SEFIP-dance) instrument. METHODS: This was a questionnaire validation study. Both professional dancers and those who use dance as a recreational activity were included in the study. For test-retest reliability, SEFIP-dance was administered to the same dancer at 2 different times, with an interval of 7 days between the moments. For construct validity, Spearman's correlation coefficient (r s) was used to determine the magnitude of the correlations between SEFIP-dance and the Numerical Rating Scale, the 36-Item Short-Form Health Survey, the Roland-Morris Disability Questionnaire for general pain, and the Örebro Musculoskeletal Pain Questionnaire. RESULTS: A total of 111 dancers were recruited and included in the study. From this total sample, a subsample of 31 was used for the calculations of test-retest reliability: when considering each item of SEFIP-dance, we observed adequate κ values (κ ≥ 0.52); considering the total score, we observed excellent reliability (intraclass correlation coefficient = 0.94). In addition, we identified adequate values for internal consistency (Cronbach's α ≥ 0.80). We observed significant correlations of the SEFIP-dance total score with the Numerical Rating Scale, 36-Item Short-Form Health Survey, the Roland-Morris questionnaire, and the Örebro Musculoskeletal Pain Questionnaire (r s varying between 0.248 and 0.489). Ceiling and floor effects were not observed. CONCLUSION: This study found that the Brazilian Portuguese version of SEFIP-dance has psychometric properties suitable for its use in dancers.
