Confirmatory Factor Analysis and Reliability of the Burn Specific Health Scale-Revised in Brazilian Burned Patients.

Abstract

The aim of the study was to analyze the factor structure and the reliability of the Brazilian-Portuguese version of the Burn Specific Health Scale-Revised (BSHS-R) in a sample of Brazilian burned adults. This study was a cross-sectional study. The internal consistency was analyzed using Cronbach's α, considering coefficients ≥.70 as appropriate. We conducted confirmatory factor analysis (CFA) to test the hypothesis that the BSHS-R Brazilian-Portuguese version has a factor structure similar to the original. We assessed the factor structure of the BSHS-R Brazilian-Portuguese version by CFA, examining three models: three-factor, six-factor, and seven-factor structure. The participants were 299 burned adults. The CFA indicated good model fit indices for the seven-factor model (root mean square error of approximation = .062; goodness-of-fit index = .844; adjusted goodness-of-fit index = .809; Akaike information criterion = 1,054.06). The seven-factor BSHS-R Brazilian-Portuguese version showed Cronbach's α of .93. The BSHS-R Brazilian-Portuguese version with seven factors is reliable and valid and measures the perceived health status construct.
