Study Background/Rationale Active duty hospitalizations for suicidal ideation, 2005-20101 1. Medical Surveillance Monthly Report, Vol. 18 (4), April 2011.
Study Background/Rationale • Results of RCT of 12-session BCBT vs. TAU for suicide attempts among military personnel: • Suicide attempts reduced by 50% in BCBT • Significant reductions in PTSD symptoms in BCBT • No differences in depression, anxiety, suicidal ideation • Crisis response planning and reasons for living anecdotally observed to be important interventions
Study Background/Rationale • Suicidal individuals experience cognitive rigidity & failed problem solving • Overestimate likelihood of negative/undesirable outcomes2 • Anticipate fewer positive events will occur in future3 • Impaired ability to consider reasons for why undesirable events will not occur • Suicidal & nonsuicidalindiv. can list equal no. of reasons2 • Suicidal individuals take longer to generate the first reason2 • When reasons are listed, hopelessness drops4 2. MacLeod. (1994) 3. MacLeod et al. (1993) 4. Schotte & Clum. (1982).
Study Background/Rationale • Crisis Response Plan (CRP) • Problem solving tool that outlines crisis management steps • Collaboratively developed by clinician and patient • Now widely used in military mental health settings, especially triage • Potential problems with CRPs in triage: • Not originally designed as a single-session intervention • Fidelity of intervention is low • Does not explicitly target suicidal intent or desire
Study Background/Rationale • Most suicidal individuals experience both desire for life and desire for death simultaneously • Reasons for living associated with lower suicidal intent and perception of suicide as solution5 • Reasons for living associated with suicidal ambivalence • Suicidal ambivalence is associated with death by suicide6 • Enhancing suicidal patients’ reasons for living can reduce risk for suicidal behaviors • Suicidal patients can list reasons for living, but take a long time to generate the first item 5. Kovacs & Beck (1977) 6. Brown et al. (2005)
Research Question(s)/Hypotheses • The crisis response plan with reasons for living (CRP+RFL) intervention will contribute to significantly decreased risk for suicide attempts and hospitalization during follow-up relative to the crisis response plan alone (CRP) and treatment as usual (TAU). • The CRP+RFL intervention will contribute to greater ambivalence about suicide and faster recall of reasons for living relative to the CRP and TAU interventions. • Greater ambivalence about suicide and faster recall of reasons for living will mediate the relationship between intervention and reduced risk for suicide attempt during follow-up.
Design and Methodology Primary outcome: Suicide attempt (SASII) Suicidal ambivalence (BSSI Items 1 & 2) Hospitalization Secondary outcomes: Suicidal ideation (BSSI, DSI-SS) Subjective suicidal intent (SBQ-R) Proposed mediator:: Reasons for living (speed of identification)
Design and Methodology Subjects 360 active duty Soldiers recruited from Ft. Carson triage • Inclusion: 18+ y/o; active duty; speaks English; current suicidal ideation and/or recent suicide attempt • Exclusion: inability to consent due to medical or psychiatric condition (psychosis, mania, etc.) Staff 2 therapists, 1 evaluator • Embed therapists into 5 mental health teams • Follow-up assessments completed by blind evaluator

Planned Analyses • Between treatment differences • Suicide attempt, hospitalization: survival curve using log-rank and Wilcoxon statistics • Ambivalence, suicidal ideation, suicide intent: mixed effects regression with repeated measures • Speed of RFL recall • Mixed effects regression with repeated measures and pairwise comparisons • Mediation of RFL recall speed • Sobel test and test of indirect effects using bootstrapping method • Fundamental voice frequency analysis • Cross-lagged actor-partner interdependence models (APIMs)
