The self-administered Cochin 17-item Scleroderma Functional scale (CSF-17) provides reliable patient-reported outcome assessment of mobility and general tasks in patients with systemic sclerosis, study data in the British Journal of Dermatology suggest.

Patients with systemic sclerosis who were enrolled in the Scleroderma Patient-centered Intervention Network Cohort (n=184) were emailed a provisional 65-item International Classification of Functioning, Disability and Health (ICF)-based questionnaire that was developed on the basis of interviews of patients with the disease.
