OBJECTIVE: To evaluate the relationships between key outcome variables,
classified according to the International Classification of Functioning,
Disability and Health (ICF), and observed and self-reported functional ability in
patients with chronic widespread pain. DESIGN: Cross-sectional with systematic
data collection in a clinical setting. SUBJECTS: A total of 257 consecutively
enrolled women with chronic widespread pain. METHODS: Multidimensional assessment
using self-report and observation-based assessment tools identified to cover ICF
categories included in the brief ICF Core Set for chronic widespread pain.
RESULTS: Relationships between ICF variables and observed functional ability
measured with the Assessment of Motor and Process Skills (AMPS) were few. Out of
36 relationships analysed, only 4 ICF variables showed a moderate correlation
with the AMPS motor ability measure. A moderate to strong correlation between
numerous ICF variables and self-reported functioning was noted. Multivariate
regression modelling supported significant contributions from pain and
psychosocial variables to the variability in self-reported functional ability,
but not to the variability in AMPS ability measures. CONCLUSION:
Observation-based assessment of functional ability in patients with chronic
widespread pain is less influenced by pain and psychosocial factors than are
self-reported evaluations. Valid observation-based assessment tools, such as the
AMPS, should be included in clinical evaluation and future research addressing
functional outcomes in this patient population.
