Abstract

Background Context

Studies have shown that pain acceptance strategies related to psychological flexibility are important in the presence of chronic musculoskeletal pain. However, the predictors of these strategies have not been studied extensively in patients with whiplash-associated disorders (WAD).

Purpose

The purpose of this study was to predict chronic pain acceptance and engagement in activities at 1-year follow-up with pain intensity, fear of movement, perceived responses from significant others, outcome expectancies, and demographic variables in patients with WAD before and after multimodal rehabilitation (MMR).

Study design

The design of this investigation was a cohort study with 1-year postrehabilitation follow-up.

Study setting

The subjects participated in MMR at a Swedish rehabilitation clinic during 2009–2015.

Patient sample

The patients had experienced a whiplash trauma (WAD grade I–II) and were suffering from pain and reduced functionality. A total of 386 participants were included: 297 fulfilled the postrehabilitation measures, and 177 were followed up at 1 year after MMR.

Outcome measures

Demographic variables, pain intensity, fear of movement, perceived responses from significant others, and outcome expectations were measured at the start and after MMR. Chronic pain acceptance and engagement in activities were measured at follow-up.

Methods

The data were obtained from a Swedish Quality Registry for Pain Rehabilitation (SQRPR).

Results

Outcome expectancies of recovery, supporting and distracting responses of significant others, and fear of (re)injury and movement before MMR were significant predictors of engagement in activities at follow-up. Pain intensity and fear of (re)injury and movement after MMR significantly predicted engagement in activities at follow-up. Supporting responses of significant others and fear of (re)injury and movement before MMR were significant predictors of pain acceptance at the 1-year follow-up. Solicitous responses of significant others and fear of (re)injury and movement at postrehabilitation significantly predicted pain acceptance at follow-up.

Conclusion

For engagement in activities and pain acceptance, the fear of movement appears to emerge as the strongest predictor, but patients' perceived reactions from their spouses need to be considered in planning the management of WAD.
