Translation into Brazilian Portuguese and validation of the five-part questionnaire for identifying XXXX .

@entity1 @entity14884 @entity8018
INTRODUCTION: @entity14884 ( @entity14884 ) is an inherited clinical condition with increased joint elasticity in passive movements. In the general population, its frequency, which can be estimated through specific methods, such as the nine-point Beighton @entity8018 score (Beighton score) and the self-reported five-part questionnaire for identifying @entity8018 (five-part questionnaire), ranges from 10% to 20%. OBJECTIVES: To validate the Portuguese version of the five-part questionnaire and to determine its sensitivity and specificity when compared with the Beighton score for diagnosing @entity14884 . METHODS: The five-part questionnaire for identifying @entity8018 was translated into Portuguese and applied to 2,523 Brazilian university students. Then, a sample with 394 randomly selected students was evaluated by use of the Beighton score, aiming at establishing the @entity14884 diagnosis. Finally, the two methods were statistically compared. RESULTS: The @entity14884 frequency was 37.01% when using the five-part questionnaire, and 34% when using the Beighton score. Considering sex, the @entity14884 frequencies according to the five-part questionnaire and Beighton score were 43.54% and 44.26% in females, and 28.44% and 16% in males, respectively. The sensitivity of the self-reported questionnaire was 70.9% and its specificity was 77.4%, with an area under the receiver operating characteristic (ROC) curve of 0.786. CONCLUSIONS: @entity14884 is frequent in Brazilian university students, and more common in @entity1 . The self-reported five-part questionnaire for @entity14884 identification, translated into Portuguese and validated, was an effective method when compared with the Beighton score for identifying @entity14884 .
