Abstract:
Body perception disturbances are a typical symptom among people with Complex Regional Pain Syndrome (CRPS). To assess it, the Bath CRPS Body Perception Disturbance Scale (B-BPDS) is a comprehensive tool which was validated in English and translated/validated in German and Japanese. To date, no French version was available. We translated the B-BPDS in French using the forward-backward method to obtain a French version (B-BPDS-F). Then, we examined its internal consistency, concurrent validity and structural validity. 32 participants were included for the first evaluation and 21 for the second. Internal consistency of the B-BPDS-F was adequate after removing item 3 on attention. B-BPDS-F was significantly correlated with pain at rest, quality of life total score and anxiety/depression dimensions. Exploratory Factor Analysis showed 2 main factors which explain 63 and 31% of the total variance. ICC was found acceptable. Our results are in line with previous work and provide a valid measurement tool in French.
