Sjögren's disease & overlap diseases
Field testing and clinical validation of the mSQUASH to measure physical activity in patients with Sjögren's disease
Authors' conclusion
The mSQUASH is a feasible, valid and reliable questionnaire to assess daily physical activity in SjD patients.
Study context
- Population
- Patients with Sjögren's disease (SjD); field testing also in SLE, GCA/PMR and axSpA263 SjD for construct validity
- Participants
- 10 / 10 / 10 / 13
- Comparison
- SjD vs SLE vs GCA/PMR vs axSpA
- SjDn = 10
- SLEn = 10
- GCA/PMRn = 10
- axSpAn = 13
- Outcome
- Construct validity and test-retest reliability of the mSQUASH in SjD

Performance
As reported in the abstract
Correlation of mSQUASH total score with ESSPRI total score (Spearman ρ)
−0.30
Correlation of mSQUASH total score with EQ-5D total score (Spearman ρ)
−0.34
Test-retest reliability, ICC (n=75 SjD)
0.84
Further findings
Field testing
- All patient groups perceived the mSQUASH as relevant and easy to complete; some minor adaptations and clarifications implemented
Subdomain correlations
- Correlations higher for ESSPRI fatigue and pain than dryness, and highest for EQ-5D activity and mobility
