@entity1 @entity409 @entity158
OBJECTIVES: To translate and culturally adapt the Shoulder @entity158 and Disability Index (SPADI) into Brazilian-Portuguese and to assess its reliability. METHODS: The first step was the translation, synthesis, back-translation, revision by the committee, pre-testing and evaluation of documents by the committee and the author of the SPADI. The revised version by the committee was applied to 90 subjects with @entity409 , aged over 18 years from different education and sociocultural levels. The items misunderstood by 20% or more of @entity1 were reformulated and reapplied until they reach values lower than 20%. The second stage consisted of two applications of SPADI to 32 @entity1 with @entity409 in a interval ranging from 2 to 7 days. The data from the translation were analyzed descriptively, the test-retest reliability by Intraclass Correlation Coefficient (ICC) and the internal consistency by Cronbach's Alpha. RESULTS: Some expressions have been adapted to the Brazilian population and the items in the @entity158 and disability subscales were changed for an easier reading in Portuguese Language. The pre-test revealed a need to change only one item of the @entity158 domain and to administer the questionnaire by interview, since it was repeated three times and in the first two applications with self-reported questionnaire the @entity1 had not been reporting their symptoms with regards to the past week and also they have not been properly used the item "Not Applicable". The test-retest reliability ranged from 0.90 to 0.94 and the internal consistency ranged from 0.87 to 0.89. CONCLUSION: After the translation and cultural adaptation, it was obtained a reliable version of SPADI-Brazil.
