Suicide is among the leading causes of death worldwide, and the risk of suicide is highest in the period immediately following discharge from inpatient psychiatric care.1Importantly, despite the enormously elevated risk during this period, nearly 50% of patients do not attend scheduled therapy after discharge. Even among those who do attend therapy, however, the skills learned in treatment may be difficult to use during the highly distressing time leading up to and during a suicide crisis. Most traditional treatments are not designed to be effective during a suicide crisis. In order to reduce the risk of suicidal thoughts and behaviors in general and specifically during the post-discharge period, interventions are needed that: (1) are easily adhered to and (2) are accessible and effective during a suicide crisis. As such, the purpose of this research study is to test an innovative, new intervention in order to develop an effective and accessible intervention for those at high risk for suicide

Inclusion Criteria:

• Adult status (18+ years)
• Admission to eligible units in our partner hospital with a reason for admission having to do with suicide risk
