Suicide prevention is the top clinical priority for VA/DoD. Suicide is one of the leading
causes of death in the United States and worldwide with suicide rates among U.S. military
Veterans doubling (27.7 per 100,000) the rate of civilian levels. Despite a rise in
prevention efforts, rates have continued to increase. Theories of suicide and
rehabilitation psychology stress the importance of the person-environment interaction in
contributing to one's disability experience. Several studies have found that the most
frequent situation precipitating suicide was a problem with a romantic partner. In
contrast, people with higher relationship satisfaction are less likely to have suicidal
thoughts. The International Classification of Functioning, Disability and Health (ICF)
identifies social engagement and communication as important components of functioning.
Prevention of suicide in at-risk Veterans is of vital importance and the quality of one's
intimate relationship is an understudied intervention target for suicide prevention. The
importance of including family members in Veterans' suicide related care is a critical
component of the National Strategy for Preventing Veteran Suicides 2018-2028, the
National Action Alliance on Suicide Prevention, and a key finding from VA/DoD patient
focus groups conducted for the 2019 VA/DoD Clinical Practice Guidelines for the
Assessment and Management of Patients at Risk for Suicide. Despite the fact that VA/DoD
recommend and Veterans desire treatments that involve family members, currently no
couple-based suicide-specific interventions exist. The goals of this CDA-II are to refine
and pilot a novel suicide-specific couple-based intervention-Treatment for Relationships
and Safety Together (TR&ST). TR&ST adapts an evidence-based intervention for suicide,
Brief Cognitive Behavioral Therapy (BCBT) for Suicide, to be dyadically focused and
integrates Cognitive Behavioral Couple Therapy (CBCT) skills.
The proposed 5-year study consists of two phases. Phase 1: treatment refinement with 12
couples (N=24) and Phase 2: pilot Randomized Controlled Trial (RCT) of TR&ST compared to
VA Standard Suicide Intervention, which will involve suicide risk assessment, VA safety
planning, Suicide Prevention Coordinator (SPC) follow-up, and referral to outpatient
mental health with 60 couples (N=120). The intervention period is 11-weeks and the entire
study period is approximately 7 months. Couples in both phases will be quantitatively
assessed at baseline, mid-treatment, post-treatment, and 3-months post-treatment. The
primary outcome to be evaluated is change in severity of suicidal ideation. Secondary
outcomes concern changes in interpersonal functioning theorized to influence suicidal
ideation and behavior.
The Specific Aims of the study are:
Aim 1 (Phase 1): refine TR&ST in a population of Veterans with active suicidal ideation
Aim 2 (Phase 2): evaluate feasibility and acceptability of TR&ST Hypothesis 1 is that
TR&ST will be feasible to deliver, as evidenced by attainment of recruitment goals,
retention rates 70%, and high credibility and expectancy ratings and satisfaction.
Aim 3 (Phase 2): estimate the preliminary impact of TR&ST vs. VA Standard Suicide
Intervention on suicidal ideation severity and proximal targets of interpersonal
functioning over 7 months to determine if a future efficacy trial is warranted.
Hypothesis 2a is that Veterans engaged in TR&ST (vs. VA Standard Suicide Intervention)
will have greater reduction in suicidal ideation severity (primary outcome) Hypothesis 2b
is that Veterans and partners engaged in TR&ST (vs. VA Standard Suicide Intervention)
will have improved interpersonal functioning (i.e., communication, bonding, relationship
satisfaction) Hypothesis 2c is that the effect of TR&ST on Veteran's reduced suicidal
ideation will be mediated by improvements in Veteran and partner interpersonal
functioning Exploratory Aim 1: examine rates of suicide related behavior for Veterans in
TR&ST (vs. VA Standard Suicide Intervention) Exploratory Aim 2: examine links between
weekly changes in suicidal ideation and relationship quality Exploratory Aim 3: examine
the impact of TR&ST on depression, PTSD, and relationship conflict
