Systemic Sclerosis Quality of Life Questionnaire (SScQoL): translation into Turkish and assessing its psychometric properties.

The Turkish version of SScQoL seems to have adequate psychometric properties and can be used to evaluate HRQoL in clinical and research settings. Key points • Turkish version of SScQoL is a valid and reliable tool for measuring health-related quality of life of patients with systemic sclerosis. • SScQoL is the only diseases-specific quality of life measurement for systemic sclerosis available in Turkish. • Patients with limited and diffuse SSc seem to be similar in terms of self-reported health-related quality of life.
