ABSTRACT
STUDY DESIGN:
Cross-cultural adaptation and psychometric analysis.OBJECTIVE:
To develop the Turkish version of the Fremantle Back Awareness Questionnaire (FreBAQ-T) and to evaluate its psychometric properties. SUMMARY OF BACKGROUND DATA There is a growing interest in the role that the disturbance of body perception may lead to long-lasting pain problems such as chronic low back pain (CLBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is a simple and low-cost way of evaluating disturbed back awareness in people with CLBP.METHODS:
The FreBAQ was translated from English into Turkish using the forward-backward-forward method. One hundred four participants with low back pain completed the FreBAQ-T. The FreBAQ-T was repeated in 15 participants after 1 week to establish test-retest reliability. Although internal and external construct validity was investigated using Rasch analysis and Spearman correlation coefficient, respectively; reliability was evaluated in terms of internal consistency by Cronbach alpha and Person Separation Index.RESULTS:
All items of the FreBAQ-T were found to fit the Rasch Model (chi-square 6.17 [dfâ=â9], Pâ=â0.723). The internal construct validity was good, overall mean item fit residual was -0.305 (standard deviation 0.369) and mean person fit residual was -0.290 (standard deviation 1.349). The reliability was good with Cronbach alpha of 0.87 and Person Separation Index of 0.82. When the test-retest was examined via differential item functioning by time, none of the items showed differential item functioning.CONCLUSION:
The FreBAQ-T is a valid, reliable, and unidimensional scale for patients with CLBP. This scale will allow assessing back-specific perception in the Turkish population with CLBP. LEVEL OF EVIDENCE 3.
