Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized controlled trial that aims to compare the effectiveness of two psychological treatment approaches: the Attempted Suicide Short Intervention Program (ASSIP) and Acceptance and Commitment Therapy (ACT). The study seeks to determine which of these two methods is more effective in reducing suicidal ideation and mental pain in individuals who have recently attempted suicide.

In this study, 60 participants with a history of suicide attempts will be randomly assigned to three groups. One group will receive ASSIP in addition to treatment as usual (TAU), the second group will receive ACT alongside TAU, and the third group will be a control group receiving TAU only. The results will be assessed using the Beck Scale for Suicide Ideation (BSSI) and the Orbach \& Mikulincer Mental Pain Scale (OMMP) at three stages: pre-test, post-test, and follow-up.

The ultimate goal of this research is to provide valuable insights into the comparative effectiveness of ASSIP and ACT interventions for suicide attempters and to contribute to evidence-based suicide prevention strategies. The findings are expected to inform clinical practice and guide future research in this field.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Background and Rationale:

Suicide attempts are a major global public health concern and one of the leading causes of premature mortality, particularly among individuals aged 15 to 29 years. In Iran, as in many countries, suicide attempts represent a critical mental health issue requiring effective, evidence-based interventions. Two therapeutic approaches have demonstrated promising results in reducing suicidal ideation and preventing repeated attempts: the Attempted Suicide Short Intervention Program (ASSIP) and Acceptance and Commitment Therapy (ACT).

ASSIP is a brief, structured, narrative-based intervention developed to address the underlying personal crisis and cognitive-behavioral mechanisms that lead to suicidal behavior. It typically involves three to four sessions, followed by long-term follow-up contacts. ACT is a third-wave behavioral therapy aimed at increasing psychological flexibility and reducing experiential avoidance, often associated with suicidal crises.

Despite evidence supporting both methods internationally, little research has compared their effectiveness in the Iranian context.

Study Overview:

This randomized controlled trial will enroll 60 adults with a recent history of suicide attempt, identified through the Eslamshahr Health Network. Participants will be randomly assigned to one of three groups:

1. ASSIP plus treatment as usual (TAU)
2. ACT plus TAU
3. TAU only (control) Interventions will be delivered in an outpatient health center setting. The ASSIP group will receive three core sessions (with a possible fourth session) delivered according to the official ASSIP manual. The ACT group will receive four to five individual sessions following the "ACT for Life" protocol, specifically adapted for suicide prevention.

Assessment and Follow-up:

The primary outcomes are suicidal ideation and mental pain, assessed using validated Persian versions of the Beck Scale for Suicide Ideation (BSSI) and the Orbach \& Mikulincer Mental Pain Scale (OMMP). Assessments will occur at baseline (pre-test), immediately after treatment (post-test), and one month after intervention (follow-up). Data will be analyzed using SPSS v27, applying descriptive statistics, analysis of covariance, and post hoc comparisons.

Significance:

This study is expected to generate context-specific evidence on the comparative effectiveness of ASSIP and ACT in reducing suicidal ideation and mental (or psychological) pain in Iranian suicide attempters. The findings will help inform mental health services in Iran and contribute to global suicide prevention strategies by clarifying which short-term, evidence-based intervention is more effective and feasible in similar healthcare settings.

Intervention Model

PARALLEL

This study is a randomized controlled trial with three parallel groups. Participants will be randomly assigned to one of these three groups. The first group will receive ASSIP alongside treatment as usual (TAU) , the second group will receive ACT alongside TAU , and the third group (the control group) will receive only TAU. All groups will receive their interventions simultaneously and in parallel for the duration of the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

ASSIP + TAU

Participants in this group receive the Attempted Suicide Short Intervention Program (ASSIP) in addition to treatment as usual (TAU).

Group Type EXPERIMENTAL

Attempted Suicide Short Intervention Program (ASSIP)

Intervention Type BEHAVIORAL

This is a brief, structured, patient-centered therapy consisting of three to four face-to-face sessions. Each session typically lasts between 60 to 90 minutes. A fourth session may be added if clinically necessary.

Treatment as Usual (TAU)

Intervention Type OTHER

Treatment as usual (TAU) is not a structured intervention within this study. It may include standard outpatient or inpatient services, pharmacotherapy, or no structured treatment, depending on individual circumstances.

ACT + TAU

Participants in this group receive Acceptance and Commitment Therapy (ACT) alongside treatment as usual (TAU).

Group Type EXPERIMENTAL

Acceptance and Commitment Therapy (ACT)

Intervention Type BEHAVIORAL

This intervention uses the "ACT for Life" protocol, which is designed to maximize recovery after suicidal crises. It consists of three components delivered over three to six individual sessions. The average number of sessions is four to five, with each session lasting approximately 60 minutes.

Treatment as Usual (TAU)

Intervention Type OTHER

Treatment as usual (TAU) is not a structured intervention within this study. It may include standard outpatient or inpatient services, pharmacotherapy, or no structured treatment, depending on individual circumstances.

Control Group (TAU only)

This control group receives only treatment as usual (TAU).

Group Type OTHER

Treatment as Usual (TAU)

Intervention Type OTHER

Treatment as usual (TAU) is not a structured intervention within this study. It may include standard outpatient or inpatient services, pharmacotherapy, or no structured treatment, depending on individual circumstances.
