Translation, transculturation and validity of the self-administered questionnaire for functionality (Systemic Sclerosis Questionnaires [SySQ]) for use in Spanish patients with systemic sclerosis and its relationship to the severity of the disease and to quality of life. ⋯ SySQ in this validated Spanish version is a suitable instrument to measure functional status in patients with systemic sclerosis.
