To evaluate the construct validity, test-retest reliability, and clinical correlates of the IPAQ and SQUASH physical activity questionnaires in patients with ankylosing spondylitis.
Construct validity was evaluated by comparing IPAQ and SQUASH against 7-day ActiGraph accelerometer data in 63 outpatients with ankylosing spondylitis.
Test-retest reliability was measured by administering both questionnaires twice, approximately 1 week apart, in 52 outpatients.
Clinical assessments of disease activity, physical function, spinal mobility, and quality of life were compared against activity measures across all 115 participants.
Total scores for the IPAQ and SQUASH correlated moderately with accelerometer output (ρ = 0.38 and r = 0.35, respectively).
Test-retest intraclass correlation coefficients were 0.83 for the IPAQ and 0.89 for the SQUASH, with Bland-Altman analyses revealing wider 95% limits of agreement for the IPAQ.
Higher physical activity across all tools correlated significantly with lower disease activity, better physical function, and higher quality of life, whereas spinal mobility correlated only with the accelerometer and SQUASH.

Implication

Observational study demonstrates modest validity and superior reliability of SQUASH over IPAQ in ankylosing spondylitis, indicating its utility for population assessments.
