Mild traumatic brain injury characteristics do not negatively influence cognitive processing therapy attendance or outcomes.

Some providers have expressed hesitation about the appropriateness of PTSD treatment for veterans with a history of mild traumatic brain injury (mTBI), given concerns that TBI-related sequelae may negatively affect PTSD treatment and/or should be the focus of treatment instead. However, research suggests that those with a history of mTBI can benefit from evidence-based PTSD treatment. To extend these findings, we examined whether specific mTBI injury markers were associated with PTSD treatment attendance and response. Iraq/Afghanistan-era veterans with PTSD and history of mTBI (N = 88) all received Cognitive Processing Therapy (CPT; either standard CPT without the trauma account or SMART-CPT, a modified version of CPT that included cognitive rehabilitation strategies). Analyses examined whether time since injury, presence of loss of consciousness (LOC) or posttraumatic amnesia (PTA), and number and mechanism of mTBIs were associated with treatment attendance or response. None of the five injury variables examined were associated with number of treatment sessions attended. Multilevel modeling indicated that injury variables did not moderate treatment response (across treatment conditions) in terms of change in PTSD and depression symptoms. There was a three-way interaction showing that individuals who denied ever experiencing LOC exhibited a greater decrease in PTSD and depression symptoms in standard CPT relative to those in the SMART-CPT. Thus, a history of mTBI should not preclude individuals from receiving standard CPT, regardless of injury characteristics. In fact, PTSD treatment should often be a first line of treatment for these veterans, given evidence of a mental health etiology to persistent post-concussive symptoms.

SMART-CPT for veterans with comorbid post-traumatic stress disorder and history of traumatic brain injury: a randomised controlled trial.

OBJECTIVE: To better concurrently address emotional and neuropsychological symptoms common in veterans with comorbid post-traumatic stress disorder (PTSD) and history of traumatic brain injury (TBI), we integrated components of compensatory cognitive training from the Cognitive Symptom Management and Rehabilitation Therapy (CogSMART) programme into cognitive processing therapy (CPT) for PTSD to create a hybrid treatment, SMART-CPT (CogSMART+CPT). This study compared the efficacy of standard CPT with SMART-CPT for treatment of veterans with comorbid PTSD and history of TBI reporting cognitive symptoms. METHODS: One hundred veterans with PTSD, a history of mild to moderate TBI and current cognitive complaints were randomised and received individually delivered CPT or SMART-CPT for 12 weeks. Participants underwent psychological, neurobehavioural and neuropsychological assessments at baseline, on completion of treatment and 3 months after treatment. RESULTS: Both CPT and SMART-CPT resulted in clinically significant reductions in PTSD and postconcussive symptomatology and improvements in quality of life. SMART-CPT resulted in additional improvements in the neuropsychological domains of attention/working memory, verbal learning/memory and novel problem solving. CONCLUSION: SMART-CPT, a mental health intervention for PTSD, combined with compensatory cognitive training strategies, reduces PTSD and neurobehavioural symptoms and also provides added value by improving cognitive functioning.

Worse baseline executive functioning is associated with dropout and poorer response to trauma-focused treatment for veterans with PTSD and comorbid traumatic brain injury.

Although trauma-focused treatment, including Cognitive Processing Therapy (CPT), effectively reduces PTSD symptoms, treatment dropout, nonresponse, and relapse are substantial. Executive functioning (EF) is essential to engage the cognitive skills involved in CPT (e.g., inhibiting/evaluating distorted thoughts, flexibly generating alternative thoughts). It was hypothesized that worse baseline EF would be associated with reduced CPT completion and responsivity. Seventy-four Iraq/Afghanistan-era Veterans with PTSD and history of mild-to-moderate traumatic brain injury were randomized to either standard CPT or modified CPT that included cognitive rehabilitation strategies (SMART-CPT). Those who dropped out of treatment prematurely performed more poorly on EF tests at baseline than treatment completers. Worse baseline performances on EF tests of working memory, inhibition, and inhibition/switching were associated with poorer response to CPT (less reduction in PTSD symptoms). In addition, a three-way interaction indicated that individuals with worse baseline cognitive flexibility did not benefit as much from standard CPT but demonstrated significant PTSD symptom improvement in the SMART-CPT condition, comparable to those with better baseline cognitive flexibility. Modifying CPT to accommodate executive dysfunction may boost treatment effectiveness and allow Veterans to fully engage in and benefit more from components of CPT (e.g., cognitive restructuring).

Contributions to Executive Dysfunction in Operation Enduring Freedom/Operation Iraqi Freedom Veterans With Posttraumatic Stress Disorder and History of Mild Traumatic Brain Injury.

OBJECTIVE: Posttraumatic stress disorder (PTSD), history of mild traumatic brain injury (mTBI), and executive function (EF) difficulties are prevalent in Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) Veterans. We evaluated the contributions of injury variables, lower-order cognitive component processes (processing speed/attention), and psychological symptoms to EF. PARTICIPANTS: OEF/OIF Veterans (N = 65) with PTSD and history of mTBI were administered neuropsychological tests of EF and self-report assessments of PTSD and depression. RESULTS: Those impaired on one or more EF measures had higher PTSD and depression symptoms and lower processing speed/attention performance than those with intact performance on all EF measures. Across participants, poorer attention/processing speed performance and higher psychological symptoms were associated with worse performance on specific aspects of EF (eg, inhibition and switching) even after accounting for injury variables. Although direct relationships between EF and injury variables were equivocal, there was an interaction between measures of injury burden and processing speed/attention such that those with greater injury burden exhibited significant and positive relationships between processing speed/attention and inhibition/switching, whereas those with lower injury burden did not. CONCLUSION: Psychological symptoms as well as lower-order component processes of EF (attention and processing speed) contribute significantly to executive dysfunction in OEF/OIF Veterans with PTSD and history of mTBI. However, there may be equivocal relationships between injury variables and EF that warrant further study. Results provide groundwork for more fully understanding cognitive symptoms in OEF/OIF Veterans with PTSD and history of mTBI that can inform psychological and cognitive interventions in this population.

Psychosocial predictors of employment status among men living with spinal cord injury.

OBJECTIVE: To explore the relationship between employment status and community access, perceived community discrimination, social support from significant others, depressive symptoms, and gender-related variables for 83 men living with spinal cord injury. STUDY DESIGN: Correlational research. SETTING: Internet-based investigation employing spinal cord injury listservs. MAIN OUTCOME MEASURE: Participant employment status. RESULTS: A forced-entry hierarchical logistic regression indicated that means of injury, community access and perceived community discrimination, social support from significant others, depressive symptoms, and men's adherence to masculine norms for primacy of work, self-reliance, and emotional control significantly predicted employment status. CONCLUSIONS: Psychosocial variables such as community access, perceived discrimination, social support from significant others, depressive symptoms, and gender identity represent important and understudied predictors of employment status among men living with spinal cord injury.

Men's adjustment to spinal cord injury: the unique contributions of conformity to masculine gender norms.

Men constitute 82% of the approximately 250,000 people in the United States living with a spinal cord injury. Unfortunately, however, little is known about the impact of men's adherence to gender norms on their adjustment to such injuries. The present investigation examined the utility of masculine norms in explaining variance in depression beyond that accounted for by commonly identified predictors of men's adjustment following spinal cord injury. As hypothesized, results suggested that men's adherence to masculine norms accounted for unique variance in their depression scores beyond that contributed by social support, environmental barriers/access, and erectile functioning. Respondents who adhered to norms stressing the primacy of men's work demonstrated lower rates of depression, whereas those who conformed to norms for self-reliance demonstrated higher depression scores. The authors discuss future research directions and potential psychotherapeutic strategies for working with men with spinal cord injuries.
