The primary objective of this study is to evaluate the efficacy of Cognitively Augmented Behavioral Activation (CABA), a new hybrid treatment for Veterans diagnosed with comorbid mild Traumatic Brain Injury (mTBI) and posttraumatic stress disorder (PTSD). The study's specific goals are to determine whether: 1) CABA reduces PTSD symptoms in Veterans with mTBI/PTSD, 2) CABA reduces cognitive-related functional impairment in Veterans with mTBI/PTSD, 3) CABA results in improvements in depression symptoms, cognitive functioning, and quality of life in Veterans with mTBI/PTSD; and 4) CABA is an acceptable treatment for Veterans with mTBI/PTSD. The overall goal is to develop an evidence-based manualized treatment for comorbid mTBI/PTSD that can be readily implemented in Veterans Health Administration (VHA) treatment settings.
Veterans historically exhibit high rates of comorbid mTBI/PTSD. Given the comorbidity and neuropsychiatric symptom overlap of these disorders, it can be difficult to determine whether problems and disruptions in functioning are due to mTBI, PTSD, or both. Hence, it is challenging for providers to know how to prioritize these patients' clinical issues and how to effectively treat them. Currently, there are no evidence-based treatments for comorbid mTBI/PTSD. Further, it is unclear to what extent existing treatments for each disorder can be adherently and effectively implemented for the other. As such, most current treatment recommendations suggest a holistic or integrated approach to treatment for comorbid mTBI/PTSD targeting symptoms and functionality rather than underlying etiology. Investigators are proposing a treatment for comorbid mTBI and PTSD that directly targets daily functioning and quality of life. The study design makes use of the convergent availability of resources at the two participating Veterans Administration Health Care Systems in Portland, Oregon, and Seattle, Washington to conduct a Randomized Controlled Trial (RCT) of CABA. The study will recruit a total of 192 Veterans less than or equal to 55 years of age, 96 participants at each site, enrolled at participating VA Medical Centers (VAMCs) who are diagnosed with both mTBI and PTSD. Eligible participants will be randomly assigned to either the CABA or Treatment as Usual (TAU) group. Participants in the CABA group will receive the CABA intervention during the first 14 weeks of their participation in the study, whereas TAU participants will continue to receive TAU (usual care in a PTSD specialty treatment clinic, but no CABA) during their participation in the study. Both groups will undergo evaluations at baseline, 7 weeks (mid-treatment), 14 weeks (post-treatment), and 39 weeks (6 month follow-up). During their study participation, all participants will continue to receive their usual medical care.

CABA uses Behavioral Activation (BA) to identify meaningful goals and activities while learning cognitive skills to aid in working toward those goals. Early sessions of CABA focus on learning about mTBI, PTSD, and lifestyle skills that can improve thinking abilities and mood. Cognitive skills taught each week include internal and external skills to help manage problems with memory, attention, and regulation of thinking processes. Investigators and patients will spend a part of each session applying the cognitive skills to managing real life situations and getting patients active in the service of personal goals.
TAU care involves psychotherapy (counseling) provided by a specialist in the treatment of PTSD. Patients will be offered individual appointments with an experienced provider on the PTSD Clinical Team (PCT). Beyond this, the specific approach will be determined by the patient and his/her provider and may include skills for managing PTSD and/or a chance for the patient to "process" his/her traumatic experiences. Additional treatments may be offered to patients, such as group classes and medications. TAU care may also include additional evaluation and/or treatment of mTBI, provided by the usual care offered in Portland or Seattle's respective neuropsychology clinics. Treatment for mTBI includes individual or group sessions, and is based on clinical need.

PTSD Symptoms From Baseline as Measured by the Clinician Administered PTSD Scale - 5
The Clinician Administered PTSD Scale (CAPS-IV; Blake et al., 1995; Weathers, Keane, \& Davidson, 2001) was used to assess initial PTSD diagnosis (DSM-IV; APA, 2000) and PTSD symptom severity across assessment time points. The CAPS is considered a "gold standard" for assessing PTSD. Items are ranked on Likert scales according to both frequency (0-4) and intensity of symptoms (0-4), yielding an overall severity score based on the sum of frequency and intensity ratings across 17 items (range 0-136) . For this study, a diagnosis of PTSD was based on a scoring rule for items to be considered present of at least a "1" on frequency and "2" on intensity, with an overall severity score of at least 45 (Weathers, Ruscio, \& Keane, 1999).

PTSD Symptoms From Baseline as Measured by the PTSD Checklist-5
The Posttraumatic Stress Disorder Checklist-Fifth Edition (PCL-5; Blanchard, Jones-Alexander, Buckley, \& Forneris, 1996; Weathers, Litz, Herman, Huska, \& Keane, 1993; Weathers et al., 2013) was used to assess participants subjective PTSD related distress. The PCL-5 is a 20 item self-report measure that assesses the presence of DSM-5 PTSD symptoms. Items are rated on a 5-point Likert scale ranging from 0 to 4 according to how much the symptom bothered the respondent over the past month. Total scores with scores range from 0-80, with higher scores indicating more symptomatic distress. Scores totaling 31 or more are associated with presumptive PTSD among military populations.
