Highlights
- •Twelve-month prospect cohort study of 188 patients with severe TBI.
- •First investigation of postinjury relation between PTS and HRQoL.

- •PTS associated with interpersonal and cognitive functioning post-TBI.
- •PTS associated with total and emotional functioning if patients ≤50 years of age.
Abstract
Objective
To investigate the relation between posttraumatic stress (PTS) symptom severity and
health-related quality of life (HRQoL) after severe traumatic brain injury (TBI).
Design
Longitudinal prospective multicenter, cohort study on severe TBI in Switzerland (2007–2011).
Setting
Hospital, rehabilitation unit, and/or patient’s living facility.
Participants
Patients with severe TBI (N=109) were included in the analyses. Injury severity was
determined using the Abbreviated Injury Score of the head region after clinical assessment
and initial computed tomography scan.
Interventions
Not applicable.
Main Outcome Measures
HRQoL (Medical Outcomes Study 12-Item Short-Form Health Survey Physical and Mental
Component Summaries) and self-reported emotional, cognitive, and interpersonal functioning
(Patient Competency Rating Scale for Neurorehabilitation).
Results
Multilevel models for patients >50 and ≤50 years of age revealed significant negative
associations between PTS symptom severity and interpersonal functioning (P<.001 and P=.002), respectively. Among patients ≤50 years of age, PTS symptom severity was significantly
associated with total functioning (P=.001) and emotional functioning (P<.001). Among all patients, PTS symptom severity was significantly associated with
cognitive functioning (P<.001) and mental HRQoL (P=.01).
Conclusions
Findings indicate that PTS symptoms after severe TBI are negatively associated with
HRQoL and emotional, cognitive, and interpersonal functioning.
