Mental health and posttraumatic stress symptoms 2 years after severe multiple trauma: self-reported disability and psychosocial functioning.

OBJECTIVES: To describe mental health and posttraumatic stress symptoms (PTSS) for patients with severe multiple trauma at 2 years postinjury. Further, objectives were to examine relationships between PTSS and factors related to the person, injury, and postinjury physical and psychosocial functioning from the time of return home to 2 years after injury. The final aim was to identify predictors of PTSS and mental health at 2 years.

DESIGN: Prospective cohort study with a 2-year follow-up.

SETTING: Hospital and community setting.

PARTICIPANTS: Patients (N=99) age 18 to 67 years with multiple trauma and a New Injury Severity Score (NISS) greater than 15 treated at a regional trauma referral center. Mean age +/- SD was 35.3+/-14.2 years; 83% were men. Mean NISS +/- SD was 34.9+/-12.7.

INTERVENTION: Not applicable.

MAIN OUTCOME MEASURES: Postinjury psychologic distress associated with depression on the Medical Outcomes Study 36-Item Short-Form Health Survey Mental Health scale and PTSS on the Post-Traumatic Symptom Scale 10 (PTSS-10) at 2 years post injury. Self-reported physical, mental, and cognitive functioning at the return home and 1 and 2 years, and coping strategies.

RESULTS: Mean PTSS-10 score +/- SD at 2 years was 25.6+/-12.2. Twenty percent had a PTSS-High score, indicating posttraumatic stress disorder (PTSD). Twenty-seven percent had Mental Health scores indicating depression. Predictors of PTSS were sex (female), younger age, avoidant coping, pain, mental health, and cognitive functioning on the return home, which explained 70% of the variance in PTSS-10 score.

CONCLUSIONS: Twenty percent had a PTSS-High score indicating PTSD at 2 years postinjury. The personal factors sex (female), younger age, and avoidant coping and the functional factors pain, mental health, and cognitive functioning predicted PTSS at 2 years.
