Mild traumatic brain injury (mTBI), also known as concussion, is a common injury sustained by Veterans. While most individuals who sustain mTBI experience a complete recovery within several weeks of injury, many Veterans with history of mTBI report frequent and long-lasting neurobehavioral complaints and functional impairment. Though research suggests that these outcomes are strongly influenced by co-occurring conditions such as post-traumatic stress disorder, depression, and chronic pain, evidence-based interventions capable of addressing this wide array of concerns are lacking. This study seeks to address this gap by evaluating the effectiveness of a brief and flexible behavioral health treatment (Problem-Solving Training for Concussion, or PST-Concussion), which was designed to be delivered by generalist providers working in VA primary care settings. If PST-Concussion is shown to be effective, this skills-focused intervention may help improve Veterans' recovery experience following mTBI.
This study will be a longitudinal randomized two-arm parallel group clinical trial. Participants will be randomized 1:1 to either PST-Concussion or treatment as usual (TAU). Participants assigned to PST-Concussion will receive six, approximately 30-minute telehealth treatment sessions. Assessments will include standard self-report and cognitive measures that will be administered at baseline, post-treatment, and three-month follow-up. The primary objective of this study will be to evaluate the effectiveness of PST-Concussion in reducing psychological distress compared to TAU. Secondary and tertiary objectives will be to evaluate whether PST-Concussion is associated with appreciable change in subjective neurocognitive functioning, objective neurocognitive functioning, psychosocial functioning, and disability and quality of life. Multi-level modeling will be used to evaluate treatment effects at post-treatment and three-month follow-up. A test of non-inferiority will be conducted to evaluate the potential durability of observed treatment effects from post-test to follow-up. A portion of participants assigned to PST-Concussion will also be interviewed at post-treatment or follow-up to gain insight into the practical impact of intervention on psychosocial functioning and quality of life.

PST-Concussion is a combined treatment consisting of brief problem-solving training, standard concussion education, motivational interviewing, goal-setting, and compensatory cognitive strategies.
Patients assigned to TAU will receive the care that they and their providers determine is necessary to best manage their presenting concerns.

RECRUITINGBrief Symptom Inventory-18 (BSI-18) Global Severity Index T-Score
The BSI-18 is a brief measure of psychological distress brought about by common somatic and affective symptoms. It has been validated for use in patients with history of TBI and is appropriate for use in primary care. Similar to a previous trial of PST for mTBI, its Global Severity Index (GSI) T-score will serve as the primary outcome measure. GSI T-scores range from 30-80, with lower scores signaling an overall lower level of psychological distress.
Time frame: Up to 24 weeks
Hopkins Verbal Learning Test-Revised (HVLT-R)
A brief test of verbal learning, recall, and recognition. Participants are read a word list over 3 learning trials, and are asked to recall as many words as possible after a 25-minute delay. Raw scores are converted to T-scores (range = \<20 to \>80), with higher scores signaling better verbal memory performance.
Time frame: Up to 24 weeks
Neurobehavioral Symptom Inventory (NSI)
A 22-item checklist of affective, cognitive, and somatosensory symptoms commonly reported after concussion. Scores range from 0 to 88, with lower scores signaling lower overall symptom reports.
Time frame: Up to 24 weeks
Wechsler Adult Intelligence Scale- Fourth Edition (WAIS-IV) Digit Span
A brief verbal attention test. Participants are presented with a sequence of digits and asked to repeat them forward and backward. Raw scores are converted to percentile ranks (range = \<1 to \>99); higher ranks signal better overall performance.
Time frame: Up to 24 weeks
World Health Organization Quality of Life - BREF (WHOQOL-BREF)
A 26-item abbreviated version of the full-length WHOQOL measure that evaluates disability and quality of life in domains such as social relationships, physical and mental health, and satisfaction with person-environment interactions. Raw scores are averaged to compute domain scores (range = 4-20), with higher scores signaling an overall higher quality of life.
Time frame: Up to 24 weeks
Inventory of Psychosocial Functioning (IPF)
An 80-item multidimensional measure of psychosocial functioning and impairment related to mental health symptoms. An overall total is calculated as the mean of all completed subscales, which include: romantic relationships, family, work, friendships and socializing, parenting, education, and self-care. Each domain scale yields a score ranging from 0-100, with higher scores indicating greater impairment.
Time frame: Up to 24 weeks
