Translation into Brazilian Portuguese, Cross-Cultural Adaptation and Validation of the Physical Activity Scale for the Elderly for Healthy Older People

Aim: Despite the availability of physical activity questionnaires in Portuguese, there is a lack of instruments specifically adapted to the Brazilian cultural context that adequately capture physical activity patterns in older adults. Therefore, this study aimed to translate and cross-culturally adapt the Physical Activity Scale for the Elderly (PASE) into Brazilian Portuguese and to assess its internal consistency and reliability. Methods: The cross-cultural adaptation involved translators, back-translators, and experts who prepared the PASE-Br version. Intraclass correlation coefficient was used to assess its reliability in 48 older adults. The final PASE-Br version was approved by consensus, with no need for pretesting changes. Result: Intra- and inter-rater assessments classified PASE-Br reliability as low to very high/excellent and moderate to very high/excellent, respectively. Internal consistency was considered acceptable (Cronbach’s alpha 0.81). Conclusion: The PASE-Br demonstrates preliminary evidence of reliability and internal consistency for estimating physical activity levels in the Brazilian older population.
