<h3>Background</h3> Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease with a usual onset in the third decade of life, when persons are committed to various social roles that adults fulfil.<sup>1</sup> When evaluating the outcomes of clinical care, social role participation is an increasingly important outcome, especially when considering diseases with substantial limitations in physical functioning such as inflammatory rheumatic diseases.<sup>2</sup> The Short Form of the Social Role Participation Questionnaire (s-SRPQ) is a questionnaire which was developed to assess effect of ankylosing spondylitis (AS) on participation.<sup>2</sup> <h3>Objectives</h3> This study aims to evaluate the reliability and validity of the Turkish version of the s-SRPQ in Turkish patients with AS. <h3>Methods</h3> The Turkish version of s-SRPQ questionnaire was obtained after a translation and back translation process. The study sample included 100 AS patients (59 males, 41 females; mean age 42.00±11.00 years; range 19 to 69 years). To assess the test-retest reliability of the Turkish s-SRPQ, the questionnaire was reapplied 15 days after the first interview (interclass correlation coefficient, ICC). Cronbach's alpha (a) was used to evaluate the internal consistency. The s-SRPQ was compared with Short Form-36 survey (SF-36), Ankylosing Spondylitis Quality of Life questionnaire (ASQoL), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), and Satisfaction With Life Scale (SWLS) for convergent validity. The internal structure of s-SRPQ was examined by factor analysis. <h3>Results</h3> For s-SRPQ/experienced physical difficulties; the individual item ICC ranged from 0.78 to 1.00 and Cronbach's alpha value ranged from 0.88 to 1.00. For s-SRPQ/satisfaction with role performance; the individual item ICC ranged from 0.93 to 0.98 and Cronbach's alpha value ranged from 0.96 to 0.99. KMO values was determined as 0.90 and 0.89 in the s-SRPQ/experienced physical difficulties and s-SRPQ/satisfaction with role performance, respectively. Bartlett's test of sphericity had a p&lt;0.001. The Turkish version of s-SRPQ/experienced physical difficulties scores negatively correlated with the SWLS and SF-36 sub-parameters scores (p&lt;0.01). There were also strong positive correlations between <i>s-</i>SRPQ/experienced physical difficulties scores and BASDAI, BASFI, and ASQoL scores (p&lt;0.01). The SRPQ/satisfaction with role performance scores positively correlated with the SWLS and SF-36 sub-parameters scores (p&lt;0.01). There were also strong negative correlations between s-SRPQ/experienced physical difficulties scores and BASDAI, BASFI, and ASQoL scores (p&lt;0.01). <h3>Conclusions</h3> Turkish version of s-SRPQ has good comprehensibility, internal consistency, and validity and is an adequate and useful instrument for the assessment of participation in Turkish patients with AS. <h3>References</h3> [1] Sieper J, Braun J, Rudwaleit M, Boonen A, Zink A (2002) Ankylosing spondylitis: an overview.
