All participants will download the tFOCUS app to their mobile phone. tFOCUS uses EMA to assess variables identified as being salient to treatment engagement and illness self-management. The application delivers algorithm-driven micro interventions to address reported problem(s). Data is transmitted to a clinician "dashboard," which can be used for remote monitoring.

Control participants will receive the currently recommended best practices of post-discharge care, including follow-up appointments, instructions, referrals and a follow-up check in.

tFOCUS integrates evidence-based strategies for self-management of severe mental illness (SMI) into a comprehensive mobile assessment and treatment system that is grounded in theoretical SMI models. The application promotes self-management strategies aimed at improving medication adherence to manage biologically driven psychiatric symptoms, increase social support to reduce the negative impact of social withdrawal, improve sleep hygiene to reduce levels of fatigue, and promote strategies for coping with persistent symptoms. tFOCUS application strategies are linked to participants' specific assessment responses, allowing for a highly personalized self-management intervention experience

The RAS is a self-report measure of aspects of mental health recovery, including hope and self-determination. The total score (sum of items) will be used and ranges from 22 to 110 with higher scores indicating higher suicidal thoughts and behaviors.
