Tailored treatments are topical in pain rehabilitation. One key issue
for correlational studies is the identification of factors having a potential
causal impact on essential treatment outcomes. OBJECTIVE: To study associations
between pain beliefs and disability with regard to the amount and time-frame of
available data. DESIGN: A prospective, correlational design.
SETTING: Ninety-two patients consulting physical therapists in primary care for
persistent musculoskeletal pain. MAIN MEASURES: The Pain Disability Index, the
Self-Efficacy Scale and the Tampa Scale of Kinesiophobia. RESULTS: Functional
self-efficacy and fear of movement/(re)injury explained variance in pain-related
disability pretreatment (adj R(2) = 0.41). Self-efficacy was the most salient
predictor. Adding data from immediately post treatment decreased explained
variance (adj R(2) = 0.25). Functional self-efficacy and fear of movement/
(re)injury lost their significant contribution in favour of pain-related
disability at baseline. Change scores in functional self-efficacy and fear of
movement/(re)injury accounted for a modest share of explained variance in change
scores of disability (adj R(2) = 0.11). Fear of movement/(re)injury but not
functional self-efficacy was related to a reliable change in pain-related
disability. CONCLUSIONS: Longitudinal data suggest that pretreatment levels of
pain-related disability and changes in fear of movement/(re)injury are most
important to immediate treatment outcomes and individual reliable change.
Disability and elevated fear of movement/(re)injury should therefore be addressed
in tailored pain treatments.
