Drivers of Suicide Mobile App Study

This study will test the newly developed WisePath for Adults ("WisePath"), a robust digital technology developed under NIAAA SBIR Fast-Track award (R44AA029868; Drs. Dimeff & Jobes, Co-PIs) that is developed to efficiently and reliably aid delivery of recommended best-practices for the treatment of suicidal ideation in adults, including suicidal individuals who also misuse alcohol. WisePath includes techniques for prevention of suicidal behaviors (ideation, planning, attempts) while providing access to support resources in the moment via a mobile app. WisePath will include evidence-based practices for suicide prevention, including for those who are suicidal and also experience other behavioral health concerns such as depressed mood, sleep problems, and misuse of alcohol. This study will test WisePath with individuals who are experiencing these problems and recently sought treatment from a primary care provider. WisePath includes: psychoeducation, behavioral skills training, crisis stabilization planning, lethal means management, brief interventions for the treatment of suicidal ideation, depressed mood, sleep problems, alcohol misuse, and messages of hope, wisdom, and insights from people with lived experience (PLE).

We will conduct a randomized controlled trial (RCT; N=120) comparing WisePath (n=60) to an active control condition (a well-regarded suicide prevention self-help app + electronic wellness resources brochure; n=60) in adults experiencing suicidal ideation. To ensure a sufficient sample of individuals who misuse alcohol, no fewer than 35% (n=42) of the sample will be comprised of individuals who experience a harmful or hazardous level of alcohol use. Participants will be randomly assigned to a condition utilizing a minimization randomization procedure to match participants across condition on suicide severity, depression severity, and alcohol misuse. Participants will be assessed at baseline, 4, 8, and 12 weeks.

We hypothesize that in comparison to the active control condition, WisePath participants will show significantly better outcomes from baseline to the 4-, 8-, and 12-week assessment points such that:

• WisePath participants will report significantly greater decreases in suicidal and alcohol misuse behaviors compared to controls
• WisePath participants will report greater increases in self-efficacy and coping with suicidal thoughts and distress, as well as use of suicide prevention strategies compared to study controls
• WisePath participants will report a higher degree of satisfaction with their respective app compared to controls

Inclusion criteria

• Resides in the United States
• 22+ years of age
• English speaking
• At risk for suicide, as evidenced by at least one of the following:
• One or more lifetime suicide attempts (ASQ item 4)
• Endorsement of any ASQ items 1 -3 (expanded from "past few weeks" in ASQ to "past 30 days" in our measures)

• Item 1: In the past 30 days, have you wished you were dead?
• Item 2: In the past 30 days, have you felt that you or your family would be better off if you were dead?
• Item 3: In the 30 days, have you been having thoughts about killing yourself?
• Currently has a primary care provider and sought care from them in the past year
• Possesses and is the primary user of an Android- or iPhone-based smartphone with a data plan

Given that alcohol misuse exponentially increases the risk of death by suicide, can exacerbate other problems, and interfere with effective treatment, we will over-recruit individuals who misuse alcohol to ensure relevance of the tool for them. No fewer than 35% of the sample will be comprised of individuals who score 8 or more on the Alcohol Use Disorders Identification Test (AUDIT), indicating a harmful or hazardous level of drinking.

To ensure a sufficient sample of individuals who misuse alcohol, no fewer than 35% of the sample will be comprised of individuals who score 8 or more on the Alcohol Use Disorders Identification Test (AUDIT), indicating a harmful or hazardous level of drinking.

Exclusion criteria

• Severe depression (PHQ-9 score of 20 or greater)
• Alcohol dependence (AUDIT score of 32 or greater)
• Acutely suicidal (affirms item 5 of the Ask Suicide Screening Questions; Are you having thoughts of killing yourself right now? Followed by endorsing intent; Have you intended to act on urges to kill yourself in the past 30 days? or planning within the past 30 days; Have you made a plan to kill yourself in the past 30 days?)
• Significant drug abuse problems (scores 6 or greater on the DAST-10)

Individuals who are excluded because of the severity of their depression, suicide acuity, and/or degree of substance use disorder will be provided with resources (i.e., the Suicide and Crisis Lifeline (988), SAMHSA's National Helpline) and encouraged to reach out to their primary care or mental/behavioral health provider.
