OBJECTIVE: To translate and cross-culturally adapt the Reintegration to Normal Living Index into brazilian portuguese, assess the content validity, test-retest reproducibility, and reliability of the instrument in individuals with multiple sclerosis.
METHOD: The process of translation and crosscultural adaptation of the Reintegration to Normal Living Index into brazilian portuguese followed standard guidelines. The study was conducted in three stages: a) cross-cultural adaptation; b) content validity using the experience of individuals with multiple sclerosis; c) reproducibility test-retest (7-day interval) and reliability by assessing internal consistency. The Content Validity Index (CVI), Intraclass Correlation Coefficient (ICC) and Cronbach's alpha were calculated.
RESULTS: Fifty patients with an average diagnosis time of 10.4 (±8.4) years were evaluated. The I-CVI for all statements in the questionnaire was above 0.90. In the analysis of test-retest reproducibility and reliability of the RNLI-BP, excellent ICC (0.911) and Cronbach's Alpha (0.953) were found. The mean score of the Reintegration to Normal Living Index was 76.0 (±23.5) in the first assessment and 76.3 (±25.3) in the second assessment.
CONCLUSION: The Brazilian Portuguese version of the Reintegration to Normal Living Index (RNLI-BP) has content validity, reproducibility and reliability in measuring participation in individuals with multiple sclerosis.
