Developing an Intervention to Promote Lethal Means Safety in Suicidal Adolescents

Study Overview
=================
Brief Summary
-----------------
Study Objective: to develop a phone-based intervention to aid parents of suicidal adolescents to adhere to lethal means safety. Lethal means counseling is the practice of educating patients and their families about limiting access to items that can be used to attempt suicide. Though lethal means counseling is standard practice in treating suicidal patients, there is little experimental literature related to its utilization across different providers and its efficacy. Further, there is a significant gap in the literature on lethal means counseling as it relates to adolescents. The proposed project will investigate a novel text message-based intervention aimed to promote lethal means safety.

Detailed Description
-----------------
Participants will be adolescents (age 12-17) who are currently enrolled in the SPARC IOP for a recent suicide attempt or significant suicidal ideation with a plan or intent and their parents or legal guardians. SPARC clinical staff will identify patients and parents who would be eligible based on inclusion/exclusion criteria provided to them. If the family is interested, the study staff will be on hand to present the study and collect informed assent from patients and consent from parent(s). Investigators will enroll up to 120 pairs of parents and teens receiving care at the SPARC clinic. Investigators will utilize a Children's Health HIPAA compliant texting services to send prompts to the parents of the teens. Phase I of the study was approved in STU-2020-0100 in which the team developed interviews and data collection guides. In Phase II, approved in STU-2021-0658, the team is conducting pilot testing of the intervention to determine if parents find it useful. In this study, Phase III, investigators will randomize the families into two groups: the first being the treatment as usual (TAU) group (N = 60) and the second being the intervention group (N = 60). Parents and guardians in the control group will not receive the text-based intervention. In the intervention group, parents of teens currently enrolled in the SPARC program will enroll in and receive text-based reminders (safety prompts and questionnaire) to adhere to lethal means safety practices twice a week, serving as an intervention to increase adherence to lethal means safety. Data will be collected at 4 time points: SPARC intake, SPARC discharge, 1 month following SPARC discharge, and 6 month following SPARC discharge. At 1-month and 6-month follow up, parents will complete Client Satisfaction Questionnaire regarding satisfaction with the intervention, a brief measure of family functioning, and a brief measure of parental-self efficacy in the context of their child's suicidality. Additionally, at 1-month and 6-month follow up, adolescents will complete questionnaires regarding their access to lethal means in the time frame and measures of suicidality and symptomatology. All 1-month and 6-month questionnaires will be completed by families digitally or over the phone.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Adolescent suicidal behavior | Adolescent suicidal behavior will be measured by Columbia Suicide Severity Rating Scale (C-SSRS) which is used to measure suicidal thoughts and behaviors in Investigational New Drug (IND) studies. The C-SSRS rates an individual's degree of suicidal ideation (SI) on a scale, ranging from wish to be dead to active suicidal ideation with specific plan and intent. The scale identifies SI severity and intensity, which may be indicative of an individual's intent to commit suicide. C-SSRS SI severity subscale ranges from 0 (no SI) to 5 (active SI with plan and intent). | 6 months | 
| Parent satisfaction as measured by CSQ-8 | Parent satisfaction will be measured by Client Satisfaction Questionnaire (CSQ-8) which is a self report measure of satisfaction with health and behavioral services received. The CSQ-8 is measured on a four point Likert scale from 1 Quite Dissatisfied to 4 Very Satisfied. Scores range from 8-32, with higher values indicating higher satisfaction | 6 months | 
| Parent suicide prevention self efficacy as measured by parent suicide prevention self efficacy scale | Parent suicide prevention self efficacy is measured by parent suicide prevention self efficacy scale which measures parent's confidence on a scale of 0 (not at all confident) to 10 (completely confident) | 6 months |
