Reliability and validity of the Spinal Appearance Questionnaire (SAQ) and the Trunk Appearance Perception Scale (TAPS)

摘要

BackgroundThe Spinal Appearance Questionnaire (SAQ) and the Trunk Appearance Perception Scale (TAPS) are questionnaires that mostly rely on drawings to assess scoliosis patients’ subjective viewpoints on their trunk deformity. Our aim was to perform an in-depth assessment of the psychometric quality of both measures, the SAQ (version 1.1) and TAPS, and compare them to provide practical recommendations.
