Suicide Attempts

The vast majority of suicides occur in low-and middle-income countries (LMICs), and evidence on effective psychotherapeutic interventions to prevent suicide that are culturally adapted to these contexts is limited. This scenario implies an urgent need for evidence-based suicide prevention strategies in Brazil. This research aims to evaluate the effectiveness of brief cognitive-behavioral therapy in preventing suicide in an outpatient setting of a Brazilian university. A randomized, controlled clinical trial with two arms, whose participants are adults who have attempted suicide or have had suicidal ideation with intent to die, will be designed. Inclusion criteria will be suicidal ideation with intent to die in the last week and/or suicide attempt in the last month. Patients will be randomly assigned to receive either a weekly 12-session supportive therapy or brief cognitive-behavioral therapy. The duration of treatment will be approximately 3 months. Both groups will have weekly individual therapy. Follow-up contact will be made 1 month and 6 months after treatment. If necessary, patients are entitled to two booster sessions during the follow-up period. The outcomes to be assessed, a priori, are suicide attempts, self-harm without suicidal intent and suicidal ideation, assessed by the Beck Scale for Suicide Ideation (BSI). Linear mixed models will be used to assess the outcomes of continuous variables, logistic regression models for categorical outcomes and survival analysis for the analysis of suicide attempts.

To inform the effective management of adolescent suicide risk by evaluating promising treatments and developing the evidence-base for interventions that are well suited for widespread adoption, sustained quality, and impact.

Suicide is a leading cause of death in Veterans. Suicide rates among Veterans have increased approximately 36% from 2001 to 2020. Veterans are at increased risk for suicide compared to non-Veterans, with the rate of suicide death being 57.3% higher for Veterans than non-Veterans. The present study will pilot test a virtual couple-based crisis response plan (CRP-C) for Veterans in order to reduce crisis symptoms and decrease suicide risk.

Suicide is the 2nd leading cause of death among adolescents, with the highest risk period for suicide being the month following psychiatric inpatient hospitalization. The investigators propose testing a brief, scalable intervention using evaluative conditioning aimed at reducing suicidal thoughts and behaviors among adolescents during and after inpatient hospitalization. Scalable interventions, such as the one proposed that reduce suicide risk during this markedly high-risk period, could result in large-scale decreases in suicide death.
