Overview
Brief Summary
In this study, the investigators will conduct a randomized controlled trial (RCT) to evaluate the efficacy of the WET-S + treatment as usual (TAU) compared with TAU among high-risk, suicidal service members with PTSD or posttraumatic stress (PTS) admitted to the Carl R. Darnall Army Medical Center (CRDAMC) acute inpatient psychiatry unit at Fort Hood, Texas. Suicide risk and PTS symptom severity are the primary outcomes. Secondary outcomes include subsequent hospitalizations for suicidal thoughts and behaviors and suicide attempts. Investigators will conduct a needs assessment with stakeholders during the RCT to develop a tool kit for WET implementation in other DoD inpatient psychiatry units.
Detailed Description
This study aims to compare a new formulation of WET referred to as WET-for suicide (WET-S) that includes crisis response planning + treatment as usual (TAU) compared with TAU among high-risk, suicidal service members with PTS admitted to the Carl R. Darnall Army Medical Center (CRDAMC) acute inpatient psychiatry unit at Fort Hood, Texas. Aim 1: Determine if WET-S reduces the presence, frequency, and severity of suicidal ideation, suicide plans, suicide gestures, suicide attempts, non-suicidal self-injurious behaviors, and rehospitalization for suicidality. Aim 2: Determine if WET-S + TAU reduces PTS symptom severity among service members admitted to an acute psychiatric inpatient unit for SI and/or attempt compared with TAU. Aim 3: Determine if reductions in PTS symptoms mediate the association between treatment condition and suicide-related outcomes (suicidal ideation, plans, gestures, attempts, non-suicidal self-injurious behaviors, and rehospitalizations). Aim 4: Develop a tool kit for WET-S implementation through a needs assessment with key stakeholders and evaluation of contextual factors among DoD inpatient facilities to determine readiness for successful implementation of WET-S. Study investigators will conduct a randomized controlled trial (RCT) to evaluate the efficacy of the WET-S + treatment as usual (TAU) compared with TAU among high-risk, suicidal service members with PTSD or posttraumatic stress (PTS) admitted to the Carl R. Darnall Army Medical Center (CRDAMC) acute inpatient psychiatry unit at Fort Hood, Texas. Investigators will conduct a needs assessment with stakeholders during the RCT to develop a tool kit for WET implementation in other DoD inpatient psychiatry units. Data will be collected in Texas. Investigators conservatively anticipate enrollment of approximately 140 service members to achieve a final sample size of 124 (n = 62 per condition) after accounting for 15% attrition. CRDAMC receives approximately 4500 admissions each year for SI/attempt. TAU on the inpatient unit consists of crisis management and stabilization. Suicide risk and PTS symptom severity are the primary outcomes. Secondary outcomes include subsequent hospitalizations for suicidal thoughts and behaviors and suicide attempts.

- •Speak, read, and write English.
Exclusion Criteria
- •Active psychosis.

Outcomes
Primary Outcomes
Change in Self-Injurious Thoughts and Behaviors Interview Scores
Time Frame: Baseline, 1-month, 4-month follow-up
The SITBI is a structured interview that assesses the presence (lifetime, past year, past month), frequency, severity, and characteristics of five types of SITB: (a) suicidal ideation, (b) suicide plans, (c) suicide gestures, (d) suicide attempts, and (e) non-suicidal self-injury. The SITBI assesses the frequency of each type of thought or behavior in the respondent's lifetime, past year, and past month, as well as the age of onset of each thought or behavior endorsed. The SITBI also assesses the severity of each thought or behavior endorsed on a scale from 0 (low/little) to 4 (very much/severe) scale, on average and at the worst point at each of those time frames.
Change in Clinician Administered PTSD Scale Scores
Time Frame: baseline, 1-month, 4-month follow-up
The CAPS-5 is a structured diagnostic interview and gold standard for assessing PTSD. It provides a dichotomous PTSD diagnosis and overall symptom severity score. Scores range from 0 to 80, with greater scores signifying more severe PTSD symptoms.
Change in medical record outcomes
Time Frame: Baseline, 1-month, 4-month follow-up
At baseline and each follow-up assessment, study staff will access participants' medical record to obtain information about current and past mental health treatment, current and past psychiatric diagnoses, current and past psychiatric medication, and history of suicidal thoughts and behaviors. If applicable, date of admission(s) to inpatient psychiatric unit, chief complaint at the time of admission(s), details of psychiatric stay(s), and length of stay(s) will also be obtained. Changes in any of these variables from baseline to follow-up will be recorded.
Change physical and mental health assessed by Military Suicide Research Consortium Common Data Elements
Time Frame: Baseline, 1-month, 4-month follow-up
Participants will provide self-report information about their physical and mental health and behaviors at each time point.
