Predictors of acute stress following mild traumatic brain injury

The aim of this study was to investigate the predictors of acute stress disorder (ASD) following mild traumatic brain injury (MTBI). Patients who sustained MTBI following a motor vehicle accident (n = 48) were assessed with a structured interview within 18 days of the trauma for the presence of ASD and administered the Beck Depression Inventory (BDI), Coping Style Questionnaire, Dissociative Experiences Scale, and the Eysenck Personality Inventory. ASD was diagnosed in 14.6% of patients and 4.2% were diagnosed with sub-syndromal ASD. BDI scores and avoidant coping were significant predictors of ASD and acute stress severity. This study provides further evidence that traumatic stress reactions occur following MTBI and highlights the possibility of identifying those who may benefit from early intervention.
