Group ("Project Life Force") vs. Individual Suicide Safety Planning RCT (PLF)

Description

Worldwide someone dies by suicide every 40 seconds. In the United States, Veterans exhibit significantly higher suicide risk when compared to the general United States population. One in five suicide deaths is a Veteran and in spite of enhanced suicide prevention services in the Veterans Administration (VA), twenty Veterans commit suicide daily. These very concerning numbers demonstrate an urgent need to develop additional, empirically validated interventions for suicidal Veterans.

One component of the VA's coordinated effort to treat high-risk suicidal Veterans, and diminish suicide risk, is through the construction of a Suicide Safety Plan. Considered a best practice, the SSP instructs one to: recognize personal warning signs of suicide; use internal coping strategies; engage social contacts that can offer support and serve as distraction from suicidal thoughts; contact family members or friends who may help resolve a crisis; provide contact information for VA professionals to help and, specify steps for how to make the immediate environment safer. The patient takes the SSP home for his or her use during (or at the onset of) a suicidal crisis. Safety planning is based on the idea that suicide risk fluctuates over time, and aims to prevent suicidal crises from escalating, and stop individuals from acting on their suicidal thoughts and urges. Research suggests creation of the SSP is effective; one study found that Veterans who present to an emergency room show decreased suicide behavior after creating a SSP.

This study aims to fill this treatment gap by examining a novel intervention integrating skills training with safety planning for high risk suicidal Veterans, "Project Life Force" (PLF). The PLF intervention augments the SSP with skills training, and psychoeducation, to maximize use and effectiveness of the plan in a group setting. This intervention's skill instruction is delivered in a group format. Research suggests groups mitigate loneliness and increase a sense of belonging, which is in line with the extensive literature supporting the interpersonal psychological theory (i.e., that those who die by suicide have a low sense of belonging. More recently, reports on the relation of "military unit cohesion" and suicide risk, suggests that increasing unit cohesion may have a protective effect. Overall, PLF aims to enhance suicide coping skills, safety planning and connection to others.

The main objective of this RCT is to examine if Veterans who are at high risk for suicide will benefit from the novel group intervention, PLF, compared to Veterans who receive TAU.The specific aims and hypotheses of PLF are:

Aim 1: To conduct a multi-site randomized clinical trial (RCT) of a group safety planning intervention, "PLF" versus individual safety planning in 265 suicidal Veterans. PLF will be compared with the comparison condition- individual safety planning, the current standard of care, designated as TAU.

Exploratory Aim 2: To test whether increased suicide coping and improved belongingness partially mediates treatment response in PLF>TAU.

Exploratory Aim 3: To test whether group cohesion partially mediates treatment response in PLF.

Exploratory Aim 4: To test whether the change in Safety Plan Quality (post intervention - baseline) is greater PLF>TAU, as well as whether the change in safety plan quality partially mediates treatment response in the follow up period.

Hypothesis A1: Compared to TAU, Veterans who participate in PLF, will demonstrate a decrease in suicidal behavior.

Hypothesis A2: Compared to TAU, Veterans who participate in PLF will show a decrease in depression and hopelessness.

Hypothesis A3: Compared to TAU, Veterans who participate in PLF will have increased compliance and attitudes towards mental health treatment.
