- Be married, or cohabitating for at least 6 months
- Willing to be randomized into either treatment condition (bCBCT + OT or bCBCT + PL)
- Agree to have assessment and treatment sessions audio/video recorded

- Have the capacity to participate in virtual care (access to internet via DSL or a cable provider, private space)
Exclusion

- Exclusion criteria for Veteran:
- Severe ongoing medical problems, including heart disease, uncontrolled hypotension (systolic blood pressure \<100 mm Hg) or hypertension (systolic BP \>130 or diastolic BP \> 80 mm Hg), and neuroendocrinological disorders (e.g., diabetes). Exclusion to be determined in collaboration with study physician following completion of physician's one-on-one appointment with Veteran and review of all relevant information (e.g., risk factors, health history, concomitant medications, etc.) from Veteran's VA medical record and study screening/assessment processes including selfreport measures and blood pressure measurement. Additionally, Veterans for whom the study physician has elevated concern, will be asked to attend an in-person visit at a VA medical center, clinic, or the Veterans Medical Research Foundation before enrollment.
- Positive screen (7+) for borderline personality disorder (BPD) as assessed by the MacLean Screening Instrument for BPD76. Exclusion to be determined following case consult by PI or other clinician.
- Pregnancy, delivery in the past 6 months, current breastfeeding, or the ability to become pregnant while not practicing an effective method of contraception.

Veteran must verbally confirm that they completed the test themselves that day. Veteran must also agree to use an effective birth control method from study entry until conclusion of treatment to prevent pregnancy. The ability to become pregnant is defined as: assigned female at birth, fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilization methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy.
- Effective birth control methods include intrauterine device (IUD), injected, implanted, intravaginal, or transdermal hormonal methods, oral hormones, a barrier contraception method (e.g., male or female condoms, diaphragm, cap), or vasectomized sole sexual partner.
- Pregnancy tests will be purchased by the study and mailed to Veteran unless PI has approved waiver of testing requirement.
