Abstract
Background and Aims: The match-mismatch (MM) model of pain, mainly investigated in laboratory situations, states that people with pain make predictions of pain by evaluating previous (painful) events. Aim of study was to examine whether the MM model could be generalized to daily life of chronic pain patients, and what the influence is of cognitive behavioral rehabilitation on the MM mechanism.
Methods: Before as well as after treatment, 100 chronic pain patients were randomly prompted 10 times a day during 7 days to complete a questionnaire concerning pain experience, pain expectation and contextual aspects (Experience Sampling). Multi-level regression techniques and path analysis were used for data-analysis.
Results: Effects of (mis)matches were in the hypothesized direction: underpredictions were followed by significant increases in predicted and experienced pain; overpredictions by significant decreases in predicted pain and matches mainly by ‘no changes’ in pain. Additionally, chronic pain patients were more likely to underpredict than overpredict pain (respectively 41.2% and 19.2% of total number of (mis)matches. The more pain control (b = −0.265; t = −2.135) or fear-avoidance (b = −0.465; t = −1.937) patients showed, the smaller the difference between the number of underpredictions and overpredictions. After treatment, the number, size and effect of mismatches decreased, particularly in case of underpredictions.
Conclusion: The MM mechanism could be applied in daily life of chronic pain patients. The results provided an indication of the importance of underpredictions in daily life of chronic pain patients, which may be influenced by fear-avoidance and pain control.
