Interventions

  • Phone call — BEHAVIORAL
    A phone call from a trained study clinician that uses a standardized phone script to (a) conduct a risk assessment and (b) recommend that the participant use their safety plan (any and all included components), which will be reviewed and revised as-needed during the call. This intervention occurs at High Risk only.
  • Text messaging — BEHAVIORAL
    A text message conversation initiated by a trained study clinician that uses a standardized text messaging script to (a) conduct a risk assessment and (b) recommend that the participant use their safety plan (any and all included components), which will be reviewed and revised as-needed during the text messaging interaction. This intervention occurs at High Risk only.
  • Automated interactive smartphone-based tool — BEHAVIORAL
    An automated interactive, smartphone-based tool that will (a) (at High Risk only) guide the participant through a risk assessment and (b) (at High and Medium/Low Risk) present recommendation to use and a review of the safety plan.
  • Non-interactive pop-up messages — BEHAVIORAL
    Automated non-interactive, static pop-up messages that recommend use of the safety plan or its components (Medium/Low Risk only).

Study Details

The goal of this study is to test the effects of just-in-time intervention strategies aimed to promote implementation of the safety plan and its components at different levels of suicidal urges and intent. The main questions the investigators aim to answer are: 1. What is the acceptability and feasibility of the just-in-time intervention strategies? 2. What are the proximal effects of just-in-time intervention strategies aimed to promote use of the safety plan and its components? 3. What internal and external contextual factors moderate the just-in-time intervention effects? Participants (adults hospitalized for suicidal thoughts or behaviors) will: * Answer questions about current suicidal thoughts on their smartphone up to 4 times each day during both hospitalization and the 4 weeks after they leave the hospital * Each time they submit a survey, be immediately randomized to receive (or not receive) a just-in-time intervention tailored to their level of current suicidal thoughts * Answer brief follow-up questions on their smartphone within a couple hours of each randomization * Provide feedback on their experience with the just-in-time interventions

Arms

  • Experimental: Just-in-time intervention for promoting use of the safety plan or its components
    Completed surveys will be assigned to a risk level (High Risk, Medium/Low Risk, or No Risk) based on self-reported level of suicidal urge and intent. Participants will be "micro-randomized" to one of the available intervention options based on the survey's risk level. All interventions will include reminders to use the safety plan or its components. At High Risk, participants will be randomized to either receive a phone call from a clinician, text messaging from a clinician, or automated interactive smartphone tool. At Medium/Low risk, participants will be randomized to receive an automated interactive smartphone tool, non-interactive pop-up messages, or no intervention. No randomization will occur (and no intervention given) at No Risk.

Primary Outcome Measure

Self-reported safety plan and coping strategy use [ Time Frame: Within two hours of each micro-randomization ]
