Pain Catastrophizing Correlates with Early Mild Traumatic Brain Injury Outcome

Abstract EN

Background.

Identifying which patients are most likely to be at risk of chronic pain and other postconcussion symptoms following mild traumatic brain injury (MTBI) is a difficult clinical challenge.

Objectives.

To examine the relationship between pain catastrophizing, defined as the exaggerated negative appraisal of a pain experience, and early MTBI outcome.

Methods.

This cross-sectional design included 58 patients diagnosed with a MTBI.

In addition to medical chart review, postconcussion symptoms were assessed by self-report at 1 month (Time 1) and 8 weeks (Time 2) after MTBI.

Pain severity, psychological distress, level of functionality, and pain catastrophizing were measured by self-report at Time 2.

Results.

The pain catastrophizing subscales of rumination, magnification, and helplessness were significantly correlated with pain severity ( r = .

31 to .

44 ), number of postconcussion symptoms reported ( r = .

35 to .

45 ), psychological distress ( r = .

57 to .

67 ), and level of functionality ( r = - .

43 to - .

29 ).

Pain catastrophizing scores were significantly higher for patients deemed to be at high risk of postconcussion syndrome (6 or more symptoms reported at both Time 1 and Time 2).

Conclusions.

Higher levels of pain catastrophizing were related to adverse early MTBI outcomes.

The early detection of pain catastrophizing may facilitate goal-oriented interventions to prevent or minimize the development of chronic pain and other postconcussion symptoms.
