This 4-year study will examine the value of a type of a brief cognitive behavioral therapy treatment for Veterans with anxiety and worry. This treatment will be delivered either in-person, or by video telehealth to the Veteran's home. The treatment will be delivered by providers at three Veterans Administration Medical Centers (Houston, New Orleans, and San Antonio). The study will compare the helpfulness of this treatment to the usual care Veterans receive for anxiety and worry. A supplement to this study will also evaluate daily discrimination experiences of Veterans based on the participant's race, ethnicity, religion, physical appearance, or other characteristics.
This 4-year, multisite trial (Houston, New Orleans and San Antonio) will use a pragmatic randomized trial design to examine the effectiveness and implementation potential of a brief cognitive behavioral therapy(bCBT) intervention for anxiety delivered either in-person or via VA Video Connect-Home (VVC-H), according to patient preference. Brief CBT will be delivered by existing Primary Care Mental Health Integration (PCMHI) providers at three large VAMCs (Houston, New Orleans, and San Antonio). Aim 1 will examine the clinical effectiveness of the bCBT intervention vs. Enhanced Usual Care (EUC) for anxiety at 4-, 8-, and 12-month follow-ups. Aim 2 will determine factors associated with bCBT response and explore Veteran demographic and clinical factors associated with VVC-H engagement. An exploratory aim will use mixed, qualitative and quantitative methods to better understand implementation successes and challenges related to delivery and impact of bCBT anxiety and VVC-H use in the PCMHI setting. The primary hypothesis is that anxiety outcomes, as measured by the General Anxiety Disorder 7-item scale (GAD-7) will be superior at 4-, 8-, and 12-month follow up for patients who are assigned to receive bCBT vs. EUC. In addition, participants will be asked to complete the Diversity Supplement measures and qualitative interview to evaluate whether sociocultural factors are associated with the severity and type of anxiety symptoms among Veterans of different race/ethnicity groups.

The proposed bCBT treatment for anxiety was specifically designed for use within VA PCMHI settings and uses a patient-centered approach to increase engagement while addressing the mental health needs of anxious Veterans. Emphasis was placed on maximizing intervention potency and minimizing intensity and duration to improve implementation value and alignment with VA PCMHI requirements. The intervention directly addresses challenges to delivery of CBT providing 1) a brief, practical model of care to address multiple anxiety conditions consistent with the PCMHI model (e.g. 4-6 sessions; measurement-based care), and 2) a clinically potent intervention that includes exposure-based skills.

GAD-7 Change
The GAD-7 is a seven-item self-report instrument for screening, diagnosis and severity assessment of anxiety disorder. It is psychometrically strong and valid for use in the primary care setting. A GAD-7 score of 10 or higher will be required for study inclusion. Treatment response will be defined as a 50% reduction in baseline GAD-7 scores. The GAD-7 total score for the seven items ranges from 0 to 21: 0-4 Minimal anxiety; 5-9 Mild anxiety; 10-14 Moderate anxiety; 15-21 Severe anxiety.
Time frame: Baseline, 4-, 8-, and 12-month
OASIS Change
The Overall Anxiety Severity and Impairment Scale (OASIS) will be a secondary measure of anxiety. Unlike the GAD-7, which will be administered by both research staff and PCMHI providers, the OASIS will only be administered by research staff, thereby avoiding response bias that may occur in the clinical setting. The OASIS is a widely used five-item measure of anxiety for primary care settings assessing anxiety frequency, anxiety severity, avoidance behaviors, social interference, and interference at work, school, or home. Each item of the OASIS instructs respondents to endorse one of five responses that best describes their experiences over the past week. Response items are coded from 0 to 4 and can be summed to obtain a total score ranging from 0 to 20. A higher score indicates a poorer outcome.
Time frame: Baseline, 4-, 8-, and 12-month
SF-12 Change
The SF-12 is a self-reported outcome measure assessing the impart of health on an individual's everyday life. Physical and Mental Health Composite Scores are computed using the score of 12 questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health. The investigators will assess quality of life using the 12-item Short Form Health Survey for Veterans (SF-12V18), an instrument adopted by VHA as a measure of functional status. SF-12V responses can be summarized in component scores for physical (PCS) and mental (MCS) functioning.
Time frame: Baseline, 4-, 8-, and 12-month
