The Measure of Activity Performance of the Hand (MAP-Hand) is
reliable and valid in patients with rheumatoid arthritis.
OBJECTIVE: To assess
the validity and responsiveness of the MAP-Hand in patients with hand
osteoarthritis. METHODS: Patients were recruited from 2 rheumatology centres. The
internal consistency of the MAP-Hand was assessed by Cronbach's alpha. Content
validity was evaluated based on patient interviews. Construct validity and
responsiveness were based on predefined hypotheses of correlation between the
MAP-Hand and concurrent measures. RESULTS: Ten men and 201 women, mean age 62.8
years (standard deviation (SD) 6.8) and disease duration 12.5 (SD 7.5) years were
included. A Cronbach's alpha of 0.86 was determined. All 18 items in the MAP-Hand
were described in the interviews. Sixty-seven percent of the correlation
coefficients for baseline scores and 75% for change scores were in correspondence
with the predefined hypotheses. A high correlation was found between the MAP-Hand
and the Australian/Canadian Hand Osteoarthritis Index function score at baseline
(rho = 0.76). A moderate correlation was found for change scores (rho = 0.52).
CONCLUSION: The content of the MAP-Hand adequately reflects described activity
limitations in patients with hand osteoarthritis. The results suggest that the
MAP-Hand has adequate internal consistency and responsiveness. Before the
MAP-Hand is used in patients with hand osteoarthritis, evaluations of reliability
and further construct validity are warranted.
