Psychometric Evaluation of the Arabic Activity-specific Balance Confidence (A-ABC) and the Arabic Prosthetic Mobility Questionnaire (PMQ)

Psychometric Evaluation of the Arabic Activity-specific Balance Confidence (A-ABC) and the Arabic Prosthetic Mobility Questionnaire (PMQ) in Saudi Lower Amputees

The primary aim of this study is to perform perform a psychometric analysis of Arabic Activity-specific Balance Confidence (A-ABC) and the Arabic Prosthetic Mobility Questionnaire (A-PMQ) through a modern psychometric approach involving Rasch analysis (RA) to enable its use among Arabic speaking population and to enhance confidence in its use patients with lower limb amputation.
