Methods Patients with physician-confirmed SSc from the University of California, Los Angeles (UCLA) Scleroderma Quality of Life Study (n = 208) received clinical examinations and completed self-report questionnaires. The structural validity of the RAI was examined through confirmatory and exploratory factor analysis (CFA/EFA). Results A tenable factor structure was not identified through CFA or EFA. Conclusion The present structural analysis did not support the use of the RAI with SSc patients. ER -
