Reliability and Validity of Turkish Version of Short Form of the Social Role Participation Questionnaire in Patients With Ankylosing Spondylitis.

Abstract

This study aims to evaluate the reliability and validity of the Turkish version of the Short Form of the Social Role Participation Questionnaire (s-SRPQ) in Turkish patients with ankylosing spondylitis. The Turkish version of s-SRPQ questionnaire was obtained after a translation and back translation process. The study sample included 100 ankylosing spondylitis patients (59 males, 41 females; mean age 42.0±11.0 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 (SF-36) survey, 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 validiy. 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. The Turkish version of s-SRPQ/experienced physical difficulties scores correlated with the SWLS and SF-36 sub-parameters negatively; and Ankylosing Spondylitis Disease Activity Index, and BASFI, and ASQoL positively. The SRPQ/satisfaction with role performance scores correlated with the SWLS and SF-36 sub-parameters positively; and BASDAI, and BASFI, and ASQoL negatively. 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 ankylosing spondylitis.
