Reducing Suicide Risk in Adolescents and Young Adults Via a Psychobehavioral Intervention to Regularize Daily Rhythms

This is a randomized control trial (RCT) with subjects randomized 2:1 (using block randomization) to BE-SMART-DR or a psychoeducational control comparator condition (CC). Participation will include research clinical/behavioral interviews and symptom self-ratings, magnetic resonance imaging (MRI) scanning, actigraphy wearables, and use of smart phones for ecological momentary assessment (EMA). Subjects will participate in 12 weekly sessions and 6-month in person follow-up. Objectives 1. Show pre-post BE-SMART-DR suicidal ideation and propensity (SI/P) decreases associated with DR regularity and quality increases 2. Show pre-post BE-SMART-DR improvements in the functioning of a brain system that subserves emotional and other behavioral control (i.e., a hypothalamus-amygdala-ventral prefrontal cortex (vPFC), (HAV), system)
