Trial Summary

What is the purpose of this trial?

This trial tests a new talk therapy called Engage & Connect, aimed at middle-aged and older adults who feel socially isolated. The therapy encourages enjoyable social activities to help improve mood and reduce suicidal thoughts by making people feel happier and more connected.

Will I have to stop taking my current medications?

The trial requires that you either be off antidepressants or on a stable dose for 8 weeks, and you should not plan to change the dose during the study. Other psychotropic drugs are generally not allowed, except for a small dose of lorazepam.

What data supports the effectiveness of the treatment Social Reward Psychotherapy for Suicidal Thoughts?

Research shows that therapies like cognitive behavioral therapy (CBT) and problem-solving therapy (PST) can help reduce suicidal thoughts and behaviors. These therapies have been effective in improving mental health outcomes for people who have attempted suicide, suggesting that similar approaches in Social Reward Psychotherapy might also be beneficial. ^{1 2 3 4 5}

Is Social Reward Psychotherapy for Suicidal Thoughts safe for humans?

The available research does not provide specific safety data for Social Reward Psychotherapy or its other names, but psychotherapy in general is considered safe for humans, with studies showing it can help reduce suicidal thoughts and behaviors. ^{1 6 7 8 9}

What makes Engage & Connect Psychotherapy unique for treating suicidal thoughts?

Engage & Connect Psychotherapy is unique because it focuses on enhancing social connections and rewarding social interactions, which can improve feelings of hope and belongingness, unlike traditional therapies that primarily target psychiatric symptoms. ^{1 10 11 12 13}

Treatment Details

Interventions

• Engage & Connect Psychotherapy
• Symptom Review and Psychoeducation (SRP)

Trial Overview 'Engage & Connect' Psychotherapy is being tested against Symptom Review and Psychoeducation (SRP) over a 9-week period to see if it improves brain functions related to positive emotions and reduces suicidality in older adults suffering from depression.

Participant Groups

Group I: "Engage & Connect" Psychotherapy Experimental Treatment 1 Intervention

Engage \& Connect is a remotely-delivered psychotherapy, aimed to increase engagement in rewarding social activities and in turn, reduce suicidality. In Engage \& Connect, depressed middle-aged and older adults with suicidal ideation work with a therapist to develop "action plans" to pursue rewarding social activities of their choice.

Group II: Symptom Review and Psychoeducation (SRP) Active Control 1 Intervention

In this intervention, the therapist will review the participant's symptoms and provide literature-based clinical explanations and clarifications about the symptoms, the course, and the causes of depression and aging processes. In SRP, the therapist reviews the depressed individual's symptoms, and level of information on depression, identifies misconceptions, and guides selection of educational material which could benefit the patient.

Findings from Research

Cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT) have been identified as effective psychotherapeutic treatments for individuals who have attempted suicide, based on recent Cochrane reviews and meta-analyses.

Despite the effectiveness of these therapies, the overall impact is small, and there are significant methodological issues in the research, indicating a need for better empirical support and wider dissemination of suicide-specific psychotherapy programs.

Cognitive behavior therapy (CBT) and problem-solving therapy (PST) both led to significant improvements in various measures related to hopelessness and suicidal ideation among suicide attempters, indicating their efficacy as treatment options.

Participants receiving CBT and PST reported higher satisfaction levels compared to those receiving treatment as usual (TAU), highlighting the potential benefits of these brief therapies in managing suicidal thoughts.

Psychotherapeutic interventions have been shown to effectively reduce suicidal thoughts and behaviors, as evidenced by several randomized controlled trials (RCTs) that demonstrate their efficacy in preventing suicide attempts.

Despite these positive findings, the current literature has significant gaps and methodological limitations, indicating a need for more rigorous research to enhance the effectiveness of suicide prevention therapies.

Individuals who attempt suicide often do not continue with treatment, indicating a significant challenge in engaging them in ongoing care.

Current evidence on the effectiveness of psychosocial interventions in reducing repeated suicidal behaviors is inconclusive, suggesting that while some groups may benefit, more research is needed to improve treatment delivery and follow-through.

The study identified five effective manualized treatments for reducing suicidality, highlighting common interventions such as a clear treatment framework, crisis management strategies, and an active therapist style, based on a comprehensive review of literature from 1970 to 2007.

While the treatments shared several key elements, the study emphasizes the need for further research to determine which specific interventions or combinations are most effective in reducing suicidal behavior.

This study aims to evaluate a blended problem-solving therapy for men at risk of suicide, combining face-to-face therapy with a smartphone app, to improve outcomes for those who have engaged in self-harm.

The primary focus is on reducing suicidal ideation, with secondary measures assessing depression, anxiety, PTSD, and overall quality of life, using a cohort study design nested within a larger trial to explore the effectiveness of the intervention.

Telehealth problem-solving therapy (tele-PST) significantly reduced suicidal ideation among low-income homebound adults aged 50+, showing an effect size of 0.31 at 36 weeks, compared to a support call.

In-person PST also reduced hopelessness and suicidal ideation, but the effect was not as strong as tele-PST, indicating that telehealth may be a more effective option for this demographic.

This study aims to systematically review and analyze the effectiveness of psychotherapy in reducing suicidal thoughts and behaviors by conducting an individual patient data meta-analysis (IPD-MA) involving adult outpatients with suicidal ideation or behavior.

The research will identify factors that may moderate the efficacy of psychotherapy, providing valuable insights for mental health practitioners to tailor treatments for individuals at risk of suicide.

The Safety Planning Intervention (SPI) is effective in reducing suicidal ideation and behavior, as well as improving depression and treatment engagement among adults experiencing suicide-related distress, based on a systematic review of 26 studies.

The SPI is adaptable and can be delivered in various formats (in-person or online) and as a standalone or combined intervention, making it a flexible tool in suicide prevention practices.

Current suicide risk models primarily focus on psychiatric disorders, but they fail to address the personal and fluid nature of an individual's experience with suicidality, highlighting the need for more patient-centered approaches.

Effective therapeutic interventions for reducing suicide risk should emphasize collaboration between therapist and patient, focusing on active participation and understanding the individual's unique crisis, while also considering the integration of biological factors into psychological treatment models.

Building a strong therapeutic alliance with suicidal patients is crucial for effective treatment, emphasizing shared responsibility for patient safety.

Three key principles—fostering a treatment alliance, exploring the reasons behind suicidal thoughts, and encouraging emotional expression—are supported by evidence from trials, highlighting their importance in reducing feelings of isolation and improving patient outcomes.

In a study of 98 young adults who had recently attempted or thought about suicide, those with poorer problem-solving skills showed greater improvement when receiving problem-solving treatment compared to those with better skills, indicating that targeting deficits can be more effective.

The findings suggest that for individuals struggling with suicidal thoughts, focusing on improving problem-solving abilities rather than leveraging existing strengths may lead to better treatment outcomes over a 6-month follow-up period.
