There currently is a paucity of well-validated instruments to
quantitatively measure physical activity (PA) levels in patients with
fibromyalgia syndrome (FMS). This study aims to determine the construct validity
and test-retest reliability of two self-report physical activity questionnaires
[short-form international physical activity questionnaire (s-IPAQ) and community
health activities model program for seniors (CHAMPS)] in a fibromyalgia
population. Methods. Thirty subjects (mean age 49.1 +/- 9.6 years; 90% females)
who met the American College of Rheumatology criteria for FMS were invited to
participate in the study. Two-week test-retest reliability was evaluated for the
CHAMPS and s-IPAQ. Construct validity was evaluated by comparing PA reported from
these questionnaires with data obtained from accelerometry (steps/week,
counts/week) and the 6-minute walk test (6-MWT). Results. CHAMPS showed greater
test-retest reliability (r = 0.58; p < 0.001) compared with s-IPAQ (r = 0.18; p =
0.15). No significant correlations were observed between the self-report PA
questionnaires and the 6-MWT or accelerometry data (p > 0.05). Conclusions. In a
fibromyalgia population, the s-IPAQ does not appear to be a reliable and valid PA
assessment tool. CHAMPS displayed moderate test-retest reliability; however, no
associations were found between CHAMPS and objectives measures of PA. In view of
the known benefits of exercise in patients with FMS, there is a need to develop
new measures or validate other existing well-established PA questionnaires.
