As of 09/2025, the study was unable to be completed due to the administrative pause of research activities at the New York State Psychiatric Institute.

The aim of this study is to develop a manualized suicide prevention intervention to improve the retention and engagement of suicidal clients. (For the purposes of this proposal, engagement is defined as return to treatment after the initial session and retention as treatment attendance in an ongoing manner.) In the prior grant received by the investigators (#R01 MH112139) a large-scale project implementing evidence-based suicide prevention practices in 165 outpatient behavioral health clinics in New York State, it was determined that several aspects of the Zero Suicide model were successfully implemented but that treatment engagement and retention of acutely suicidal clients was far from optimal.

This project will have two phases; only the second phase is considered a clinical trial. In the first phase, the investigators will conduct qualitative interviews with clients engaged in outpatient behavioral health for suicide-related reasons, as well as outpatient behavioral health staff (peer specialists and clinicians) with experience working with suicidal clients, to determine to determine client, clinician and situational facilitators and barriers of suicidal clients' engagement in ongoing care. Specifically, interviews will assess if the proposed interventions of shared decision-making (SDM), structured phone outreach (SPO) and peer support are acceptable and feasible from both a client and staff perspective and perceived to be effective in enhancing treatment engagement and retention and decreasing suicidal ideation and behavior. The investigators will also conduct secondary quantitative data analyses with administrative data obtained during the previously-funded project to examine characteristics of those who did not engage or remain in treatment and/or had self-harm behavior during the implementation period, to identify clients who may benefit from additional support or assistance at the outset of treatment and during ongoing care.

In the second phase of the study, the investigators will use the findings from the first phase to develop a manualized treatment engagement and retention protocol and conduct a small pilot study to assess the protocol's feasibility and acceptability to clients and staff (peer specialists and clinicians) and preliminary effectiveness, as indicated by client satisfaction and engagement.

Suicide is the 10th leading cause of death in the US, killing more than 47,000 Americans each year. US suicide deaths have increased dramatically, a staggering 62% increase over the past two decades. While suicide research has made great strides in the development of "best practices" for screening, risk assessment, suicide-specific clinical interventions, and follow-up protocols, there is a striking gap between assessment and intervention development and the implementation of these practices in typical clinical settings.Furthermore, very little research has explored if the "best practices" recommended by clinical experts and researchers are deemed feasible, acceptable, or even desirable by clients experiencing suicidal thoughts and behavior.

• Has experience working with clients enrolled in behavioral healthcare for suicide-related reasons
• Willingness to participate in training and deliver the pilot intervention
• Willingness to complete the pre-training, post-training, and 1-month follow-up assessment
