Peer Mentorship to Reduce Suicide Attempts Among High-Risk Adults

Study Overview
=================
Brief Summary
-----------------
Amid consistently worsening suicide rates, in 2012 the U.S.Surgeon General's National Strategy for Suicide Prevention proposed to change the narrative about suicide prevention to include a focus on promoting hope and belongingness. Despite hopelessness and thwarted belongingness being among the most replicated risk factors for suicide, many widely implemented suicide prevention efforts instead emphasize the identification of acute suicide risk and referral to mental health treatment services. However, there are very few health service interventions known to reduce suicides among those identified as high risk. Those interventions shown to be effective have not achieved the wide scale implementation necessary to alter the trend of increasing suicide deaths. New interventions are needed, and one promising, scalable intervention with a novel approach to addressing the risk factors advocated by the Surgeon General is peer mentorship. A peer mentorship intervention, PREVAIL, has been piloted in a two-site randomized controlled trial (N=70) and is acceptable and feasible with enrollment of nearly half of eligible high-risk patients, mean completion of over 6 mentorship sessions, and 85% of sessions meeting fidelity standards for addressing the intended targets of hope and belongingness. The aims of this hybrid effectiveness-implementation study are: Specific Aim 1: Determine the effectiveness of the PREVAIL peer mentorship intervention for reducing suicide attempts and suicidal ideation among recently hospitalized adult psychiatric patients at high risk for suicide. Specific Aim 2: Examine the mechanisms of peer mentorship by measuring the effects of PREVAIL on potential mediators,including hope and belongingness. Specific Aim 3: Identify barriers and facilitators to implementation of PREVAIL.

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: are age 18 years or older, are currently admitted to an inpatient psychiatric unit and have medical record documentation of suicidal ideation or suicide attempt at the time of admission, have a Beck Suicide Scale score of 5 or higher for the 1-week period prior to admission, are fluent in English, are able to be reached reliably by telephone. Exclusion Criteria: substantially cognitively impaired (according to the Mini-Cog), unable to provide informed consent for any reason (including incompetency), determined by the patient's attending psychiatrist that peer mentorship is not appropriate due to unstable psychosis, cognitive disorder, or severe personality disorder, already receiving or intending to receive peer mentorship (i.e., sponsor from Alcoholics Anonymous) or group-based peer support on a biweekly or more frequent basis, residing more than 50 miles from any peer mentor, planning to be discharged to another inpatient or residential facility, or receiving electroconvulsive therapy

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Peer Mentorship intervention<br>A Peer Specialist will be making weekly follow-up contact with study participants in the community or by telephone for 3 months following hospital discharge. The content of the peer mentorship interactions will be based on the manual developed by the study team and will address protective factors such as hope and belongingness. | Behavioral: Peer mentorship<br>* The peer mentor will meet with the participant for the first time while the participant is still in the hospital. Sessions will be scheduled according to the participant's preferences, with a suggested maximum frequency of twice weekly for the first two weeks, weekly for weeks 3 to 8, and then every other week for the last month. Allowable meeting locations include public places in the community (e.g., coffee shop, park), the participant's home, or a research clinic space or by phone. Session content is flexible and allows for the peer mentor to provide general supportive listening, validation, and sharing. Session duration is on average 1 hour with at least 15 minutes discussing hope or belongingness according to semi-structured conversation guides. The session structure and content are intentionally highly flexible to allow for genuineness in the peer relationship, thereby increasing acceptability and implicit belongingness.<br>* Other names: PREVAIL;|
| Active Comparator: Enhanced Usual Care (EUC)<br>The EUC condition will consist of a caring message from the study team via e-mail or text message (based on the participant's preference) 24-72 hours after discharge. An example message is, We hope things are going well for you since you left the hospital. If you wish to reply, we'd be glad to hear from you. A list of local mental health resources will be available if participants reply and during the 3 and 6-month follow-up assessments. The EUC condition is modeled on prior studies of caring letters and brief contacts by health professionals after suicidal crisis and national recommendations to provide post-crisis follow-up contacts. | Behavioral: Enhanced Usual Care<br>* The EUC condition will consist of a caring message from the study team via e-mail or text message (based on the participant's preference) 24-72 hours after discharge.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Suicide attempts (measured by the Columbia Suicide Severity Rating Scale) | Any suicide attempt as measured according to an electronic self-report version of the Columbia Suicide Severity Rating Scale (CSSR-S). The definition of suicide attempt for the primary outcome will consist of any actual suicide attempt, aborted suicide attempt, or interrupted suicide attempt according to the CSSR-S. | 6-months | 
| Suicidal ideation (measured by the Beck Suicide Scale (BSS)) | Patient's current suicidal ideation as measured by the Beck Suicide Scale (BSS). The BSS is a self-report 19-item scale preceded by five screening items. The BSS and its screening items assess thoughts, plans and intent to commit suicide. All 24 items are rated on a three-point scale (0 to 2). Total scores could range from 0 to 48 (if the screening items are included). No specific cut-off scores exist to classify severity. Increasing scores reflect greater suicide risk. | 6-months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Suicide attempts (measured by the medical record) | Any suicide attempt as notated in the patients electronic medical record. The definition of suicide attempt for the primary outcome will consist of any actual suicide attempt, aborted suicide attempt, or interrupted suicide attempt. | 6-months | 
| Self efficacy to avoid suicidal action (measured by the Self Efficacy to Avoid Suicidal Action Scale) | Patient's self efficacy to avoid suicidal action, as measured by the Self Efficacy to Avoid Suicidal Action Scale (SEASA). To indicate level of confidence, respondents rate each item on a 6-point scale (0%, 20%, 40%, 60%, 80%, 100%). Lower scores on the SEASA were found to be associated with a higher incidence and greater severity of suicide attempts. | 6-months | 
| Suicidal ideation (measured by the Beck Suicide Scale (BSS)) | Patient's worst-point suicidal ideation as measured by the Beck Suicide Scale (BSS). The BSS is a self-report 19-item scale preceded by five screening items. The BSS and its screening items assess thoughts, plans and intent to commit suicide. All 24 items are rated on a three-point scale (0 to 2). Total scores could range from 0 to 48 (if the screening items are included). No specific cut-off scores exist to classify severity. Increasing scores reflect greater suicide risk. | 6-months |
