Abstract

Background: The Patient-Rated Elbow Evaluation (PREE) is a commonly used self-reported outcome measure in patients with elbow dysfunctions. Aims: The purpose of this study was to conduct an exploratory factor analysis (EFA) of the newly translated and cross-culturally adapted Patient-Rated Elbow Evaluation-Arabic version (PREE-AR). Also, to examine its floor and ceiling effects. Patients and Methods: An EFA using the principal component analysis (PCA) method was conducted on a sample of 88 participants with elbow pain. The oblique (nonorthogonal) rotation method was used. The Eigenvalue of 1.00 was used as a cutoff point to retain a factor. A scree plot was produced to visually examine the eigenvalues. Item loading on factors with a value greater than 0.4 was considered enough to show a satisfactory inclusion in the structure. A floor or a ceiling effect was considered to be present if more than 15% of participants scored at the lowest or the highest scores respectively. Results: The Kaiser-Meyer-Olkin (KMO) value of 0.891 with Bartlett's test of sphericity (P<0.001) justified the appropriateness of running the factor analysis.The analysis produced a three-factor structure which accounted for 66% of the total variance. Most of the “function" items loaded on factor number1 with less loading of the “pain" items of the three-factor structure. All participants scored outside the 15% threshold of the highest and the lowest total score of the questionnaire. Conclusion: The newly adapted PREE-AR items are loaded on a three-factor structure and the questionnaire does not have a floor or a ceiling effect.
