简要总结
Suicide is a national crisis, especially among older Veterans for whom evidence-based suicide prevention efforts are lacking. This proposal responds to the national priority to develop and improve interventions for suicide prevention, with a focus on at-risk older Veterans. The randomized control trial will compare VA usual care, which is suicide safety planning, with brief Problem Solving Therapy and suicide safety planning. This study uses Problem Solving Therapy because it has support from our pilot data and from secondary data analysis from other studies for reducing late life suicide risk. This treatment also has support for alleviating two key risk factors for late life suicide risk, functional disability and executive dysfunction, and thus this study will examine how older Veterans with varying levels of functional disability and executive functioning respond to treatment to inform future targeted implementation. In accordance with national priorities, existing infrastructure in Problem Solving Training could be expanded to support more rapid VA-wide implementation.
详细描述
The proposed randomized control trial will examine the efficacy of a brief behavioral treatment for reducing suicidal ideation and for increasing reasons for living in older Veterans at risk for suicide. Two common issues in older adults, functional disability and executive dysfunction, increase suicide risk and will be examined as moderators and mediators of treatment outcomes. The proposed study will examine Problem Solving Therapy (PST) using a protocol that teaches skills to address emotional and practical barriers to effective problem solving. The VA usual care practice of collaborative safety planning will be the control condition, herein referred to as enhanced usual care (EUC). For participant safety, Veterans enrolled in PST will also receive EUC. The study design is random assignment to the treatment, PST plus EUC, or the control condition, EUC only. Both the treatment and the control are evidence-based interventions delivered in six sessions. The study will occur at VA Palo Alto (primary site) and VA Syracuse/VA Canandaigua (secondary site). The assessments and treatments will be conducted entirely by phone. Longitudinal assessment of suicidal ideation and reasons for living will occur at eleven timepoints: baseline, after each of the six weekly treatment sessions, posttreatment (7 weeks), at 1-, 3-, and 6-month follow-up. The recruitment goal is 150 Veterans over a five-year period with 75 participants randomized to each treatment. Veterans must be 60 years or older, report suicide ideation, and meet diagnostic criteria for a depressive disorder, anxiety disorder, and/or posttraumatic stress disorder to be eligible. Veterans will be excluded and referred for other services if they have psychotic symptoms, bipolar disorder, or severe OCD; certain alcohol/substance use disorders; severe or unstable medical conditions; recent head injury (past year); terminal illness; positive cognitive screen indicative of possible dementia; or if they are unable to participate in the study or follow-up sessions. Recruitment will occur through multiple strategies at VA, Vet centers, and in the community to ensure the feasibility of recruiting a total of 75 Veterans at each site. To meet this recruitment goal, the primary and secondary site will each enroll 2 to 3 Veterans per month. Fidelity ratings of audiotaped treatment sessions will be made by independent raters on 20% of sessions. Mixed effects modeling will be used to estimate the effect of treatment versus the control for the outcomes of suicidal ideation and reasons for living. Models will covary for demographics, medical and psychiatric comorbidity, and psychotropic use. For the primary aim, models will determine whether PST plus EUC is associated with a larger treatment effect compared with EUC only for suicidal ideation and reasons for living. Secondary aims will determine if baseline functional disability and executive dysfunction moderate treatment outcomes, and whether a change in these two variables from baseline to posttreatment are significantly associated with (mediate) change in suicidal ideation and reasons for living. The tertiary aims will use qualitative methods to assess Veteran satisfaction with the treatment and control including the types of problems with which treatment helped them, and suggestions for improving it for future Veterans. The current VA/DoD Clinical Practice Guidelines (CPGs) for suicide do not list treatment options specifically for older Veterans despite the majority of VHA patients being 55 years or older. Thus, evidence-based outcomes from the proposed work have potential to inform the CPG recommendations for using PST with Safety Planning and/or Safety Planning alone with older Veterans. Dissemination of the treatment could be supported by expanding existing VA training infrastructure in problem solving based interventions.

结局指标
主要结局
Geriatric Suicide Ideation Scale (GSIS)
时间窗: Change across 11 timepoints: baseline, after each of the 6 weekly treatment sessions, posttreatment (7 weeks), 1-, 3-, and 6-month follow-up.
Geriatric Suicide Ideation Scale (GSIS) will assess SI over time. This 31-item self-report measure has four factors (suicide ideation, death ideation, loss of personal and social worth, and perceived meaning in life). The total score will serve as the outcome measure. Total scores range from 31 to 155. Higher scores indicate greater severity of suicide-related thinking. Internal consistency is excellent ( alpha = .90), with strong test-retest reliability (r = .86 over 1- to 2-month period). Construct and discriminant validity have been established. The GSIS will be administered at 11 timepoints: baseline, after each of the 6 weekly treatment sessions, posttreatment (7 weeks), 1-, 3-, and 6-month follow-up.
Reasons for Living - Older Adult Scale (Short RFL-OA)
时间窗: Change across 11 timepoints: baseline, after each of the 6 weekly treatment sessions, posttreatment (7 weeks), 1-, 3-, and 6-month follow-up.
Reasons for Living - Older Adult Scale (Short RFL-OA) is a 30-item questionnaire of positive attitudes, coping ability, \& religious and family RFL. Items include areas of importance to older populations, (e.g., family reasons). The total score will be the outcome measure. Total scores range from 30 to 180, with higher scores indicating that one places greater importance on different protective factors for not trying to kill oneself by suicide. Internal consistency is excellent (alpha = .94). Construct validity is established in older adults. The RFL-OA will be administered at 11 timepoints: baseline, after each of the 6 weekly treatment sessions, posttreatment (7 weeks), 1-, 3-, and 6-month follow-up.
