    AbstractThe present study aimed to translate and validate the Scleroderma Health Assessment Questionnaire (SHAQ) for Persian-speaking patients (SHAQ-P), using a cross-sectional study. This cross-sectional study included SSc patients with 2013 ACR/EULAR criteria. The SHAQ was translated using a "forward-backward" method. HAQ-DI and SSc-HAQ scores were calculated from the patient-answered questionnaires. Rheumatology experts assessed the face and content validities of the SHAQ-P. Psychometric properties of the SHAQ-P were then assessed: Structural validity was analyzed using principal component factor analysis. Discriminant and convergent validities were measured on subgroups of the initial patient population. Test-retest reliability was measured on patients who filled the SHAQ-P again after 1 month. The Scale-CVI-average (S-CVI/Ave) score for content validity was 88.7%. Face validity was measured to be 68.17% using the QQ10 questionnaire. Factor analysis revealed a two-factor structure with 20 out of 26 questions loading on the first factor (N = 285). One-way ANOVA showed that patients with a higher number of involved organs had higher average HAQ-DI and SSc-HAQ-scores (N = 60, P = 0.019 and 0.023, respectively). HAQ-DI and SSc-HAQ-scores were significantly correlated with the physical component score of SF36 (N = 31, correlation coefficient =  - 0.65 and  - 0.72, respectively). Reliability testing after one month demonstrated that HAQ-DI and SSc-HAQ-scores were significantly correlated with their initial (N = 40, correlation coefficient = 0.86 and 0.84, respectively), proving that the Persian SHAQ was a valid and reliable questionnaire to evaluate scleroderma patients' quality of life.© 2023.
