Ohio State University191 enrolled

Overview

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.

Exclusion Criteria: * Medical or neurologic condition or neurocognitive dysfunction that would interfere with the study * Current or past manic/hypomanic episode, schizophrenia, or psychotic symptoms * Deafness in either ear * Currently pregnant or trying to become pregnant * Electroconvulsive therapy (ECT) within the past 6 months * Current moderate to severe substance use disorder * Lack of fluency in English * Positive alcohol breathalyzer test and/or acute drug intoxication the day of the fMRI scans * Unwilling or unable to sign the informed consent document * Under 18 years old at the time of enrollment * Traumatic brain injury from a suicide attempt or another event * Presence of ferrous-containing metals within the body * Inability to tolerate small, enclosed spaces without significant anxiety * Individuals enrolled as controls: no lifetime history of any DSM-5 disorder * Individuals enrolled as controls: no lifetime history of suicide ideation or intent

Outcomes

Primary Outcomes

Frontolimbic neural circuit activation and connectivity

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.

Time frame: Pre-treatment, Post-treatment, and 6-months follow-up.

Suicidality

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).

Time frame: Pre-treatment, Post-treatment, 1-week post-intervention, monthly post-intervention, and 6-months post-intervention.

Secondary Outcomes

Markers of negative affectivity

Acoustic startle electromyographic (EMG) response, behavioral data (i.e., reaction times and self-report scales) during lab tasks.
