Suicide and attempted suicide are major public health issues in the U.S., accounting for almost 45,000 deaths in 2016, and over 1 million attempts each year. There is an urgent need for interventions based on evidence- based principles that decrease suicidal behavior and are feasible to deliver to large numbers of patients at times when their risk for suicide is high. In this treatment development project, we propose to develop and test a narrative-based video intervention for people with suicidal behavior or plan being discharged from psychiatric hospitalization. In response to the need for treatment over this transition, we previously developed a 6-month, in-person and telephone, clinician-delivered, psychosocial intervention called Coping Long Term with Active Suicide Program (CLASP) for patients being discharged from psychiatric hospitalization. CLASP targets key risk factors associated with suicidal behavior in order to reduce subsequent risk. In this project, we propose to develop a new intervention, called LifePlans, based on the CLASP model but using an easily disseminable video-based format in which real patients discuss their history of suicidal behavior and coping strategies. Based on previous research, we believe that having people with lived experience tell their own stories has the potential to be engaging and to catalyze behavior change. LifePlans will consist of 5, 30-min episodes that highlight patients’ experiences consistent with the CLASP model: 1) developing a personalized “Life Plan” to stay safe and restrict means, 2) clarifying valued life domains and related goals to improve hopefulness, 3) using problem solving to cope with illness, 4) improving communication with family/friends to increase social support, and 5) adhering to outpatient treatments. This study will have 3 phases. In phase 1, we will interview patients with a history of psychiatric hospitalization for suicidal behavior about their life experiences and coping history. We will invite a subset back to be interviewed on camera for a series of documentary-style videos that will form the basis of LifePlans. After the filming of additional clinician-related content and with feedback from a Patient and Family Advisory Council, we will create 5, 30-min episodes of LifePlans and accompanying patient workbook that illustrate key CLASP principles using narrative methods. We will then conduct an open trial (n=10; phase 2) and a pilot RCT (n=40; phase 3) to test the feasibility/acceptability of LifePlans for hospitalized patients with a pre-admission suicide plan/attempt. Patients will be assessed at baseline, discharge, 1, and 6 months post-discharge on suicidal behaviors (primary), suicidal ideation, psychiatric symptoms, functioning, rehospitalization rate, and possible mechanisms. We will examine feasibility and acceptability (rate of video viewing, engagement, satisfaction, recruitment/retention). In the RCT, we will examine treatment differences (within relevant co...
