Peer Mentorship to Reduce Suicide Attempts Among High-Risk Adults

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.
