Abstract

Background: Maladaptive illness perceptions are known to contribute to the development of persistent post-concussive symptoms three to six months after mild traumatic brain injury (mTBI), but it is unclear which role these perceptions play in the chronic phase. This study examined which illness perceptions impact post-concussive and psychological symptoms in the chronic phase post-mTBI. Methods: This observational study used data from 112 adults who experienced persistent symptoms following mTBI and were referred for multidisciplinary treatment. Measures included a short version of the Illness Perception Questionnaire (IPQ-K), the Rivermead Post-Concussion Symptoms Questionnaire (RPQ) and the Brief Symptom Inventory 18 (BSI 18). Results: Specific illness perceptions were unique predictors of post-concussive symptoms (understanding, identity, duration and emotional response) and anxiety and depression symptoms (understanding and emotional response). Conclusion: Although the etiology of persistent post-concussive symptoms is multifactorial, the finding that specific illness perceptions contribute to experienced symptoms in the chronic phase post-mTBI underline the importance of psychoeducation in this population.
