The primary aim of the present study is leverage existing infrastructure to develop novel technological features for a novel personalized smartphone intervention system, called the Mobile Application to Prevent Suicide (MAPS), and to establish feasibility, acceptability, safety, and estimate key parameters for primary outcomes (i.e., suicidal ideation and behavior; re-hospitalization), and target mechanisms.

Patient Satisfaction
Measured using the Client Satisfaction Questionnaire, a self-report measure of satisfaction with treatment. Scores range from 8 to 32, with higher scores representing higher satisfaction.
Time frame: 1 month
Acceptability of Research (Recruitment)

Time frame: Baseline
Acceptability of Research (Dropout)
Measured by dropout rate.
Time frame: 6 months
Acceptability of Research Procedures
Feedback on qualitative interview.
Time frame: 1 month
Acceptability of MAPS Intervention
Feedback on qualitative interview.
Time frame: 1 month
Satisfaction with MAPS Intervention
Measured by protocol completion rate.
Time frame: 4 weeks
Ecological Momentary Assessment (EMA) Adherence
Number of assessments completed out of total
Time frame: 4 weeks
Suicidal Ideation and Behavior
Will be assessed using the Columbia Suicide Severity Rating Scale, items from the Modified Scale for Suicidal Ideation, and ecological momentary assessment of suicidal ideation and behavior. The Columbia Suicide Severity Rating Scale can provide presence/absence of suicidal ideation and suicidal behavior, as well as a suicidal ideation score ranging from 0 to 5 with higher scores representing more severe ideation, and a suicidal ideation intensity rating from 0-25 with higher scores representing more intense ideation.
Time frame: 6 months
Rehospitalization
Number of inpatient rehospitalizations will be assessed using the Treatment History Interview and medical records review.
Time frame: 6 months
Emergency Department Visits
Number of emergency department visits will be assessed using the Treatment History Interview and medical records review.
Time frame: 6 months
Use of MAPS Intervention-delivered Coping Strategies (target mechanism)
Coping strategy use will be measured in three ways: (1) when participants are prompted to use a coping strategy via MAPS, followup prompts ask whether or not they used the coping skill, (2) in each EMA survey, participants are asked whether or not they used any coping skills since the last survey, and (3) the system provides output with regard to how many times participants dial a support contact phone number through the MAPS app.
Time frame: 4 weeks
Reduction of Negative Affect (target mechanism)
Negative affect will be measured using Positive and Negative Affect Scale (PANAS-X) items on ecological momentary assessment surveys. Each emotion item on the PANAS-X is rated on a 1-5 scale based on how participants feel, with 1 indicating "very slightly or not at all" and 5 indicating "extremely."
Time frame: 4 weeks
Self-Efficacy (target mechanism)
Coping self-efficacy will be measured using the Coping Self-Efficacy Scale. Self-efficacy for seeking mental health care will be measured by the Self-Efficacy to Seek Mental Health Care Scale. The total score can range from 0-260; the higher the score, the higher the level of coping self-efficacy.
