Abstract

Purpose: To psychometrically test the Evaluation of Daily Activity Questionnaire in seven
musculoskeletal conditions.
Materials and Methods: 1200 people with: ankylosing spondylitis; osteoarthritis; systemic
lupus erythematosus; systemic sclerosis; chronic pain; chronic upper limb disorders; or
Primary Sjögren’s syndrome completed the Evaluation of Daily Activity Questionnaire,
Health Assessment Questionnaire and Short-Form Health Survey v2. We examined internal
construct validity using Rasch analysis, internal consistency, concurrent validity with the
Health Assessment Questionnaire and Short-Form Health Survey v2. Participants repeated
the Evaluation of Daily Activity Questionnaire to assess test-retest reliability.
Results: The 12 domains satisfied Rasch model expectations for fit, local dependency,
unidimensionality and invariance by age and gender, in each musculoskeletal condition.
Internal consistency was consistent with individual use (Cronbach’s alpha >0.90); concurrent
validity was strong (Health Assessment Questionnaire: rs =0.60 to 0.92; Short-
Form Health Survey v2 Physical Function: rs = -0.61 to -0.91) and test-retest
reliability excellent (Intra-Class Correlation Coefficient(2,1) = 0.77 to 0.96).
Conclusion: The Evaluation of Daily Activity Questionnaire satisfied Rasch model
requirements for construct validity and has good reliability and validity in each MSC. The
Evaluation of Daily Activity Questionnaire can be used as a measure of everyday activity in
practice and research with people with musculoskeletal conditions.
