• Lead Sponsor: Ohio State University

Brief Summary

The current study is a clinical trial, meaning a research study in which human subjects are prospectively assigned to one or more interventions to evaluate the effects of those interventions on health-related behavioral outcomes. Specifically, male and female adults with current suicidal intent will be randomly assigned to receive either a 1-hour session of crisis response planning (CRP) or a 1-hour session of standard crisis risk management (Treatment as Usual). The effects of both conditions on changes in emotion regulation, behavioral inhibition, stress reactivity, and suicide risk will be evaluated post-intervention and at six-month follow-up. Additional assessments of changes in mood and suicidality will be collected daily during the first 10-days following intervention, and then monthly for a duration of six months. A cohort of healthy controls is included in the study but are not randomized to either treatment condition. The investigators hypothesize the following: 1) A single session of CRP will acutely change suicide risk and 2) Individuals who receive CRP will show sustained improvements in measures of suicidality when compared to individuals who received the Treatment as Usual intervention.

Arm && Interventions

Group	Intervention	Description
Crisis Response Planning (CRP)	Crisis Response Planning	The crisis response planning (CRP) session will last between 30 minutes to 1-hour. It will occur face-to-face with a trained study therapist. The CRP session involves the following standard suicide intervention strategies: supportive listening, provision of crisis resources, and referral to a mental health professional (if not already established). The CRP active component involves a collaborative process in which the therapist invites the patient to share the events, symptoms, and contextual factors leading up to and surrounding the participant's suicidal crisis. Next, the patient and therapist identify the patient's personal warning signs for an emotional crisis, self-management coping skills, patient's reasons for living, and sources of social support. These components are written, by the patient, on an index card. The index card serves as a concrete reference for patients in the real-world.
Crisis Risk Counseling	Crisis Risk Counseling	The crisis risk counseling session will last between 30 minutes to 1-hour. It will occur face-to-face with a trained study therapist. It will include the following standard suicide intervention strategies: supportive listening, provision of crisis resources, and referral to a mental health professional (if not already established). The therapist will conduct a semi-structured suicide risk assessment interview, after which subjects will complete a self-guided safety plan worksheet. The worksheet takes approximately 10-minutes to complete and will be done independently.

Primary Outcome Measures

Name	Time	Method
Frontolimbic neural circuit activation and connectivity	Pre-treatment, Post-treatment, and 6-months follow-up.	Task-induced activity in frontolimbic neural circuits measured with fMRI. Core regions of interest are: ventral prefrontal cortex, dorsal prefrontal cortex, inferior frontal gyrus, insula, and dorsal anterior cingulate cortex.
Suicidality	Pre-treatment, Post-treatment, 1-week post-intervention, monthly post-intervention, and 6-months post-intervention.	Self-reported suicide ideation, intent, behaviors and urges will be repeatedly assessed throughout the protocol using the Self-Injurious Thoughts and Behaviors Interview-Revised (SITBI-R), Beck's Scale for Suicidal Ideation (SSI), Lethality Rating Scale, and Suicide Cognitions Scale - Revised (SCS-R).

Secondary Outcome Measures

Name	Time	Method
Mood and psychiatric symptoms	Pre-treatment, Post-treatment, 1-week post-intervention, monthly post-intervention, and 6-months post-intervention.	Mood states and general depression and anxiety symptoms are repeatedly assessed throughout the protocol using the Beck Depression Inventory (BDI-II), Beck Anxiety Inventory (BAI), Beck Hopelessness Scale, Snaith-Hamilton Pleasure Scale (SHAPS), UPPS-P Impulsive Behavior Scale, and Validated Visual Mood Analog Scales (VMAS).
Markers of negative affectivity	Pre-treatment, Post-treatment, and 6-months follow-up.	Acoustic startle electromyographic (EMG) response, behavioral data (i.e., reaction times and self-report scales) during lab tasks.
