Development and preliminary evaluation of a measure ofself-efficacy of Self-Management in ARThritis: Self-Management in Arthritis (SMART)
Authors' conclusion
The novel Self-Management in Arthritis (SMART) questionnaire incorporates 20 items to assess efficacy for five domains of self-management of arthritis. Preliminary psychometrics are promising with unidimensional subscales, strong internal consistency, and acceptable test-retest reliability.
