OBJECTIVE: To examine the influence of depression on postconcussion symptom
reporting in patients following mild traumatic brain injury (MTBI).
Sixty patients referred to a specialty clinic following MTBI, 58 outpatients with
Structured Clinical Interview for DSM-diagnosed depression, and 72 healthy
community control participants. Participants with MTBI were divided
into 2 subgroups on the basis of self-reported symptoms of depression (23
MTBI-depressed, 37 MTBI-not depressed). All participants completed a
postconcussion symptom questionnaire. MAIN OUTCOME MEASURE: British Columbia
Post-concussion Symptom Inventory. RESULTS: There were significant differences in
total reported postconcussion symptoms among all 4 groups (all P < .002; Cohen's
d = 0.68-3.24, large to very large effect sizes; MTBI-depressed > depressed
outpatients > MTBI-no depression > healthy controls). There were significant
differences in the number of symptoms endorsed (P < .05), with the highest number
of symptoms endorsed by the MTBI-depressed group, followed by depressed
outpatients, MTBI-no depression, and healthy controls. CONCLUSIONS: Patients who
experience MTBIs and who have a postinjury recovery course complicated by
significant depression report more postconcussion symptoms, and more severe
symptoms, than (a) outpatients with depression, and (b) patients with MTBIs who
do not have significant symptoms of depression.
