Abstract

Abstract : Objectives: People with spondyloarthritis (SpA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) have identified the importance of understanding how their disease and its treatment impacts on their social roles. This requires a reliable and valid standardised measure, and this study evaluates these measurement properties of the Social Role Participation Questionnaire (SRPQ). Methods: 109 participants (44 with AS, 65 with PsA) completed questionnaires on demographics, participation measures (SRPQ, Keele Assessment of Participation (KAP), Late Life Disability Instrument (LLDI)), disease severity (physician global) and activity (pain, fatigue, Bath Ankylosing Spondylitis Disease Activity Index), psychological measures (depressive symptoms (Hospital Anxiety and Depression Scale), Illness Intrusiveness)) and function (Health Assessment Questionnaire, Bath Ankylosing Spondylitis Functional Index). After testing scaling properties, test-retest reliability of the SRPQ was evaluated using intraclass correlation coefficients (ICC) and hypotheses of construct validity were evaluated using correlation coefficients. Results: Patients with AS had a mean age of 40 years and 65% were male, whereas patients with PsA had a mean age of 53 years and 63% were male. Although there were some differences between AS and PsA participants in their social role participation, scaling properties were good for both groups. ICCs were >0.90 for the satisfaction subscales of the SRPQ. For construct validity, SRPQ satisfaction subscales were moderately correlated with the KAP and LLDI (0.64–0.78), and less satisfaction was associated with higher disease severity and activity, more depressive symptoms, more illness intrusiveness and more disability (coefficients −0.67 to −0.88). Conclusion: Social role participation is an important concept for people with SpA, and the SRPQ is a reliable and valid measure for use with people with AS and PsA.
