Participants and Methods: The current study assessed individuals between the ages of 18 and 60 who recently experienced a traumatic injury (N=213), which resulted in an mTBI for 76% of the sample. Individuals completed the Peritraumatic Dissociative Experiences Questionnaire (P-DEQ).

Associations between all three constructs were first assessed with bivariate correlations. Next, to assess whether P-DEQ scores were associated with mTBI symptoms after accounting for PTSD symptom severity, a linear regression was run with mTBI symptoms as the dependent variable, and PCL-5 scores entered as the first independent variable in the model, and P-DEQ scores as the second independent variable. Results: Of a possible total of 13 different mTBI symptoms, participants reported a mean of 5.47 symptoms (SD = 3.47). Mean PDEQ scores were 26.72 (SD = 9.0), and mean PCL-5 scores were 28.36 (SD=18.54). Peritraumatic dissociation was significantly, positively correlated with total number of mTBI symptoms. (r = .346, p <.001). MTBI symptoms were also positively correlated with PCL-5 scores (r = .344, p < .001), and PCL-5 scores were significantly correlated with peritraumatic dissociation (r = .461, p < .001). In the linear regression, after accounting for the relationship between PCL-5 sores and mTBI symptoms (r=.344, p < .001), peritraumatic dissociation was also significantly associated with mTBI symptoms, accounting for an additional 4.4% of variance (β = .238, p <.001). Overall PTSD symptom severity and peritraumatic dissociation accounted for 16.3% of variance in mTBI symptoms. Conclusions: Results suggest that individuals who experience peritraumatic dissociation during a traumatic injury event also experience a greater number of mTBI symptoms, even after accounting for PTSD symptoms. In a clinical context, these findings suggest the importance of an integrative approach when assessing symptoms of mTBI and symptoms of peritraumatic dissociation. Further exploration of the relationship between mTBI and peritraumatic dissociation is a necessity in order to better understand how peritraumatic dissociation may be associated with risk for mTBI.

Objective:

Traumatic brain injury (TBI) can result in emotional numbing, derealization, reduced awareness, and depersonalization. Dissociation at the time of trauma, or peritraumatic dissociation, is associated with later emotional detachment, memory impairment, and perceptual alterations. Literature consistently suggests that peritraumatic dissociation in the acute aftermath of a traumatic event is a predictor to developing posttraumatic stress disorder (PTSD). Many studies on peritraumatic dissociation and PTSD exclude mild traumatic brain injury (mTBI) from the inclusion criteria. The aim of this study is an attempt to bridge the gap in the literature and show significance in the association between peritraumatic dissociation and mTBI symptoms.

Participants and Methods:

The current study assessed individuals between the ages of 18 and 60 who recently experienced a traumatic injury (N=213), which resulted in an mTBI for 76% of the sample. Individuals completed the Peritraumatic Dissociative Experiences Questionnaire (P-DEQ). At two weeks post-trauma, individuals also completed self-report measures that assessed mTBI symptoms on a continuous scale (number of symptoms). and the PCL-5 to measure symptoms of PTSD. Associations between all three constructs were first assessed with bivariate correlations. Next, to assess whether P-DEQ scores were associated with mTBI symptoms after accounting for PTSD symptom severity, a linear regression was run with mTBI symptoms as the dependent variable, and PCL-5 scores entered as the first independent variable in the model, and P-DEQ scores as the second independent variable.

Results:

Of a possible total of 13 different mTBI symptoms, participants reported a mean of 5.47 symptoms (SD = 3.47). Mean PDEQ scores were 26.72 (SD = 9.0), and mean PCL-5 scores were 28.36 (SD=18.54). Peritraumatic dissociation was significantly, positively correlated with total number of mTBI symptoms. (r = .346, p <.001). MTBI symptoms were also positively correlated with PCL-5 scores (r = .344, p < .001), and PCL-5 scores were significantly correlated with peritraumatic dissociation (r = .461, p < .001). In the linear regression, after accounting for the relationship between PCL-5 sores and mTBI symptoms (r=.344, p < .001), peritraumatic dissociation was also significantly associated with mTBI symptoms, accounting for an additional 4.4% of variance (β = .238, p <.001). Overall PTSD symptom severity and peritraumatic dissociation accounted for 16.3% of variance in mTBI symptoms.

Conclusions:

Results suggest that individuals who experience peritraumatic dissociation during a traumatic injury event also experience a greater number of mTBI symptoms, even after accounting for PTSD symptoms. In a clinical context, these findings suggest the importance of an integrative approach when assessing symptoms of mTBI and symptoms of peritraumatic dissociation.
