Self-monitoring
Self-monitoring will involve completing one brief smartphone-based survey (at a fixed time) per day on suicidal thoughts and related affect states and experiences over the past day during the four weeks after psychiatric hospitalization.
JITAI
The JITAI will involve prompts to complete additional randomly timed self-monitoring surveys throughout the day. When suicidal thoughts are reported on any self-monitoring survey, random assignment to receive or not receive a series of automated smartphone-based messages that recommend using specific coping strategies from either a personalized safety plan or general evidence-based coping strategies that others tend to find helpful.
Self-guided SSI
The brief (10-12 minute) online self-guided SSI will help individuals identify and address barriers to using coping strategies for suicidal thoughts. It may be delivered up to three times during the four weeks after hospitalization for those who do not sufficiently respond to the initial (self-monitoring only or self-monitoring plus JITAI) interventions.
Clinician-delivered SSI
The clinician-delivered SSI will consist of a brief (30-minute) Zoom or phone meeting in which a study clinician will help individuals identify and address barriers to using coping strategies for suicidal thoughts. Those who do not sufficiently respond to the initial (self-monitoring only or self-monitoring plus JITAI) interventions may receive up to three clinician-delivered SSIs during the four weeks after hospitalization.
