Abstract
Background
Social role participation (RP) is a key outcome in patients with ankylosing spondylitis (AS). The Social Role Participation Questionnaire (SRPQ) assesses RP, its limitations, and satisfaction with performance.
Objective
This study aimed to translate and culturally adapt the SRPQ into Turkish and evaluate its validity and reliability in individuals with AS.
Methods
The SRPQ was translated and culturally adapted following established guidelines. A total of 129 Turkish-speaking patients with AS were included in this multicenter, cross-sectional study. Internal consistency was evaluated using Cronbach's alpha, and test-retest reliability was assessed using the Intraclass Correlation Coefficient (ICC). Construct validity was evaluated through correlations with the AS Quality of Life (ASQoL) Scale, Short Form Health Survey 36 (SF-36), and the Work Productivity and Activity Impairment (WPAI) scale.
Results
The Turkish SRPQ showed good to excellent internal consistency (Cronbach's alpha, 0.734–0.963) and test–retest reliability (ICC, 0.736–0.963). The physical difficulty dimension correlated strongly with the ASQoL (
r
= 0.756), WPAI-Q6 (
r
= 0.694), and the SF-36 physical functioning score (
r
= −0.658) (all

p

Conclusion
The Turkish version of the SRPQ is a valid, reliable, and culturally appropriate instrument for assessing social RP in Turkish-speaking patients with AS.
