What is being tested?
The study compares usual recovery support with a new method using smartphones (SARC-YA) after treatment discharge. Participants will get a smartphone, data plan, apps for daily assessments, feedback, behavioral tracking, and self-help tools to prevent relapse.See study design
What are the potential side effects?
There may not be traditional medical side effects; however, participants might experience stress or anxiety from constant monitoring or reliance on digital devices which could impact their mental health.

Experimental Treatment
Active Control
Group I: Smartphone Addiction Recovery Coach (SARC) - Assisted Relapse PreventionExperimental Treatment1 Intervention
Participants in the experimental condition will receive a smartphone, a calling/texting/data plan, and the SARC-YA mobile applications for the first 6 months post treatment discharge. Experimental participants will 1) complete a 2-3 minute recovery-focused ecological momentary assessment (EMA) at 5 random times a day, receive feedback on their current answers, and provided access to behavioral charting of their past answers over time; and 2) receive continuous access to a suite of self-initiated ecological momentary interventions (EMI) to support their recovery via tool box of coping tools, apps related to getting support, and apps related to maintaining a healthy lifestyle.
Group II: Recovery Support as Usual ControlActive Control2 Interventions
Participants in the control and experimental condition will have access to post treatment recovery support services as usual.
