Discussion

Cross-sectional survey finds strong internal consistency and test-retest reliability of CHAI in chronic disease management.

The CHAI shows strong internal consistency with a Cronbach's alpha of 0.85, indicating reliability in measuring health activation.
In a sample of 572 adults, known-group validity was confirmed with higher CHAI scores in individuals with chronic diseases, reflecting better health activation.
Cognitive interviews used in Phase 1 indicated acceptable content validity with a Scale-Level Content Validity Index of 0.86, highlighting minor wording issues.
Test-retest reliability was confirmed with an ICC of 0.802, suggesting the CHAI tool can reliably measure health activation over time.

Lee et al. (2025) studied this question.
