Reliability and validity of the Exercise Benefits/Barriers scale in the elderly

Confiabilidad y validez de la Exercise Benefits/Barriers Scale en ancianos

OBJECTIVE: Assess the reliability and validity of the Exercise Benefits/Barriers Scale (EBBS) in the elderly. METHODS: The reliability was assessed by internal consistency (Cronbach's alpha) and by the test-retest Kendall's W. To verify the construct validity it was used a correlation between the EBBS results and the personal and clinic variables. RESULTS: The Cronbach's alfa of the EBBS was 0.94. The test-retest value was 0.60. The variables that presented association with the EBBS were: level of education (p = 0.02), practice of physical activity (p = 0.0001), with whom one resides (p= 0.032) and lifestyle (p= 0.0001). CONCLUSION: The statistical analysis revealed that the translated version of the EBBS is valid and reliable however, its use is recommended in different scenarios due to regional differences in Brazil, in order to have the validity of the instrument widely exploited.
