Construct Validity of the Braden Scale for Pressure Ulcer Assessment in Acute Care: A Structural Equation Modeling Approach.

Construct Validity of the Braden Scale for Pressure Ulcer Assessment in Acute Care: A Structural Equation Modeling Approach. Ostomy Wound Manage. 2017 Feb;63(2):38-41 Authors: Chen HL, Cao YJ, Shen WQ, Zhu B Abstract The Braden Scale is the most widely used pressure ulcer risk assessment system in the world. To investigate its construct validity using structural equation modeling (SEM), a secondary analysis of retrospective data of patients admitted to an acute care facility was conducted using the records of 2588 patients who were at risk for pressure ulcers and admitted between January 2013 and December 2013. Data were extracted to an Excel sheet and analyzed, including demographic characteristics (ie, patients age, gender, weight, and disease spectrum), as well as total Braden scores and subscale scores. The SEM was set according to modification indices suggestion. The original Braden Scale model was supported by χ2(9) = 22.854, CFI = 0.902, GFI = 0.974, root mean square error of approximation (RMSEA) = 0.092, indicating inadequate model fit. After modification according to software indices, χ2(2) = 2.052, CFI = 0.999, GFI = 0.999, RMSEA = 0.020 indicated an acceptable fit of the model (final model). The factor loadings of 6 subscales were all significant (P <.001), with .147 for nutrition, .137 for activity, .167 for friction and shear, .825 for sensory perception, .626 for mobility, and .556 for moisture subscale. The nutri...
