Interventions and Outcome Measures

Arms

no intervention: Standard ED care

experimental: Standard ED care with a text-based intervention

This arm incorporates adolescent-centered (A-C) and parent-centered (P-C) texting components

Parents in the intervention arm will receive up to 3 text messages per day over six weeks after ED discharge: daily A-C text and up to two P-C messages. The P-C component includes an embedded micro-randomized trial (MRT), and parents will be randomized twice each day over the six-week intervention to either receive or not receive a P-C message.

Interventions

Text-based intervention

Parents randomized to the texting intervention will receive up to 3 messages each day for 6 weeks: The intervention is comprised of adolescent-centered (A-C) texts focusing on parental adherence to recommended suicide prevention strategies to promote adolescents' safety and parent-centered (P-C) texts focused on improving parents' own well-being.

Primary outcome measure

  • Aim 1 (primary aim): likelihood of suicidal behavior (actual, interrupted, or aborted attempts) [ Time Frame: 12-week follow-up ]
  • Aim 2 (secondary aim) severity of parental stress [ Time Frame: Up to 6 weeks ]
