A Comparison of Two Brief Suicide Prevention Interventions Tailored for Youth on the Autism Spectrum

Study Overview
=================
Brief Summary
-----------------
Rates of suicide have increased significantly over the past two decades, particularly among youth. Compared to the general population, autistic people are significantly more likely to think about suicide, attempt suicide, and die by suicide. Autistic individuals have identified suicide prevention as a top research priority; however, little is known about how to best help autistic youth at risk for suicide. The purpose of this study is to compare the effectiveness, feasibility, and acceptability of two suicide prevention strategies tailored for autistic individuals: the Safety Planning Intervention tailored for Autistic individuals (SPI-A) and SPI-A plus structured follow-up contacts (SPI-A+).

Detailed Description
-----------------
This study includes three aims: Aim 1: Among autistic youth (age 12-24) at risk for suicide, compare the effectiveness of SPI-A vs. SPI-A+. The primary outcomes of interest are suicidal ideation (SI) and suicidal behavior (SB). Secondary patient-centered outcomes are mental health treatment initiation and engagement, quality of life, well-being, skills to manage SI, access to lethal means, safety plan use, and acute care services for suicidality. Aim 2: Compare implementation outcomes of acceptability and feasibility for the two interventions from the perspectives of patients, clinicians, and health system administrators. Aim 3: Explore patient characteristics that may moderate the relationship between intervention and SI and SB.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Safety Planning Intervention Tailored for Autistic Individuals<br>The Safety Planning Intervention Tailored for Autistic individuals (SPI-A) is a brief collaborative intervention that results in an individually tailored plan designed to lower the short-term risk of suicide in autistic youth. | Behavioral: Safety Planning Intervention tailored for Autistic Individuals<br>* To develop the SPI-A, clinicians work collaboratively with patients, and when indicated, their family members, to create a list of concrete coping mechanisms to be enacted leading up to or during a crisis. This list can be depicted in writing or pictorially, depending on patient preference. As part of the intervention, patients (and family members, when appropriate) also identify warning signs that signal the need to use the safety plan, as well as a detailed plan for reducing access to lethal means. SPI-A is a stand-alone intervention without a follow-up component.<br>* Other names: SPI-A;|
| Active Comparator: Safety Planning Intervention Tailored for Autistic Individuals Plus Structured Follow-Up Contacts<br>The Safety Planning Intervention Tailored for Autistic individuals plus structured follow-up contacts (SPI-A+) is a multi-component intervention comprised of SPI-A and structured follow-up consisting of at least 2 brief contacts. | Behavioral: Safety Planning Intervention Tailored for Autistic Individuals Plus Structured Follow-Up Contacts<br>* SPI-A+ includes SPI-A plus a structured follow-up component. The structured follow-up component of SPI-A+ includes three elements: A brief risk assessment and mood check Review and, if needed, revision of SPI-A Support related to outpatient mental health treatment initiation<br>* Other names: SPI-A+;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in suicidal ideation and behavior | The Columbia-Suicide Severity Rating Scale (C-SSRS) is a clinical interview that measures suicidal ideation (range 0-5, with higher scores indicating more severe ideation) and suicidal behavior (count of total number of actual attempts, interrupted attempts, aborted attempts, and preparatory acts or behavior). The C-SSRS will be administered at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Through 12 months of follow-up | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in mental health treatment utilization | The Service Assessment for Children and Adolescents (SACA) is an interview designed to gather information on the patient participants' use of mental health services, including residential (e.g., hospital), outpatient (e.g., outpatient mental health clinic), and school (e.g., counseling) services. The SACA will be administered at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Change in quality of life | The Patient-Reported Outcomes Measurement Information System (PROMIS) Autism Battery - Lifespan (PAB-L) is a subset of PROMIS measures that has been validated for assessment of quality of life among autistic individuals. The PAB-L youth self-report includes four domains: Subjective Well-being, Relationships, Emotional Distress, and Health. Items are rated on a 1-5 scale, with higher scores indicating a greater presence of the measured construct. Patient participants will complete the PAB-L at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Change in well-being | Well-being will be measured with the Outcome Rating Scale (ORS), a 4-item visual analog scale assessing functioning in individual, interpersonal, social, and overall functioning over the past week. Item scores range from 0-10, with higher scores indicating better functioning. Patient participants will complete the ORS at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Change in skills to manage suicidal ideation | The Suicide-Related Coping Scale (SRCS) assesses knowledge of and confidence in using coping strategies and supports to manage suicidal thoughts and urges. The SRCS items are rated on a 5-point scale (strongly disagree to strongly agree). Higher scores indicate greater coping skills to manage suicidal crises. Patient participants will complete the SRCS at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Change in access to lethal means | The patient participants will answer the three access to lethal means questions from the Adapted Behavioral Risk Factor Surveillance System Survey (BRFSS), selected from the PhenX Toolkit, at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. These questions capture whether firearms are present in the home and, if so, how they are stored (e.g., loaded and unlocked). | Up to 12 months | 
| Change in safety plan use | The Brief Safety Plan Use Scale (BSPUS) will be used to assess the extent to which patient participants have utilized their safety plans since the prior assessment timepoint (e.g., How many times did you use the safety plan since last meeting? Where have you been keeping the safety plan?). Patient participants will complete the BSPUS at 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Change in acute care services for suicidality | The Service Assessment for Children and Adolescents (SACA) will be used to assess patient participants' acute care services for suicidal thoughts and behaviors. The SACA will be administered at baseline, 1-month follow-up, 6-month follow-up, and 12-month follow-up. | Up to 12 months | 
| Intervention acceptability | Patient, clinician, and health system leader participants will complete the Acceptability of Intervention Measure (AIM), a widely used four-item measure that can be administered to a wide range of stakeholders to determine the extent to which they believe an intervention is acceptable. Items are rated from 1-5, with higher scores indicating greater acceptability. Patient participants will complete the AIM at the 1-month follow-up timepoint. Clinician and health system leader participants will complete the AIM in Year 1 and Year 4 of the study. | Patient Participants: 1-month follow-up; Clinician and Health System Leader Participants: up to 4 years | 
| Intervention feasibility | Patient, clinician, and health system leader participants will complete the Feasibility of Intervention Measure (FIM), a widely used four-item measure that can be administered to a wide range of stakeholders to determine the extent to which they believe an intervention is feasible. Items are rated from 1-5, with higher scores indicating greater feasibility. Patient participants will complete the FIM at the 1-month follow-up timepoint. Clinician and health system leader participants will complete the FIM in Year 1 and Year 4 of the study. | Patient Participants: 1-month follow-up; Clinician and Health System Leader Participants: up to 4 years |
