Efficacy Trial of Stress Check-Up

Study Overview
=================
Brief Summary
-----------------
Untreated posttraumatic stress disorder (PTSD) is associated with high societal and individual costs. Effective interventions for symptoms of posttraumatic stress (PTS) exist but are underutilized by those who could benefit, especially among active duty military. This study will develop and test a brief telephone-delivered motivational enhancement intervention (MET) for military personnel (active, reserve, or national guard) serving in the Army, Air Force, or Navy who are experiencing symptoms of PTS, but who are not currently engaged in PTS treatment. The goal of the intervention is to decrease stigma around seeking care, increase knowledge about treatment options, increase engagement in help-seeking behavior, all leading to reductions in PTS symptoms.

Detailed Description
-----------------
The health and well being of military personnel, and consequently the capacity for optimal functioning of military units, are compromised by posttraumatic stress disorder (PTSD). PTSD is associated with high personal and societal costs. Post-deployment rates of PTSD range from 5-20%; approximately 8% of combat exposed military personnel develop new onsets of PTSD. PTSD is frequently comorbid with other psychiatric disorders. Untreated PTSD is associated with high rates of suicide, medical services utilization, relationship impairment, legal difficulties, decreased worker productivity, and decreased military readiness. While PTSD treatment can be effective, individuals with PTSD may not seek treatment. Drop out and medication noncompliance are common. Moreover, military personnel encounter both real and perceived barriers to seeking treatment. Given the availability of effective treatments contrasted with the low rates of military personnel who present and complete treatment, figuring out how to connect individuals with PTSD symptoms into treatment and then helping them to stay engaged is a high priority. Motivational enhancement therapy (MET) has shown promise in promoting treatment entry and enhancing both retention and successful outcomes. A brief, telephone-delivered MET called a check-up, has shown promise in promoting self-initiated behavior change as well as voluntary treatment entry, enhanced retention, and more successful outcomes for substance abuse. Despite these promising findings, no work has focused on adapting MET for enhancing self-referral and treatment seeking with individuals with PTSD who are active duty and who are not already in treatment. Active duty military face additional challenges to entering treatment than veterans and thus specific research is necessary to evaluate whether similar programs would be efficacious for active duty personnel. Adapting the check-up application with military personnel is warranted for three key reasons: (1) it has the potential of overcoming barriers to treatment-seeking, i.e., stigma and apprehension of a negative impact on one's military career; (2) it has the potential of attracting voluntary participation; and (3) protocols for disseminating this low cost intervention for use with deployed military can readily be developed and evaluated.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Motivational Enhancement Therapy<br>The MET intervention will consist of three 45-90 minute telephone delivered sessions that will be staggered to occur 1 week, 1 month, and 2 months after the baseline assessment. | Behavioral: Motivational Enhancement Therapy<br>* The MET intervention will consist of three 45-90 minute telephone delivered sessions that will be staggered to occur 1 week, 1 month, and 2 months after the baseline assessment. The first MET session intervention will involve a counselor using motivational interviewing (MI) strategies to establish an empathic therapeutic relationship and focus learning about the PTSD symptoms the participant is experiencing and exploring ambivalence about seeking treatment services. MET sessions 2 and 3 will focus on identifying and responding to risk factors for dropping out of treatment (increases in ambivalence, avoidance behavior, concerns about stigma, life chaos), identifying and responding to barriers to participant's active engagement in treatment, and facilitating enrollment in alternate therapeutic resources if necessary.<br>|
| Active Comparator: Treatment as Usual<br>The treatment as usual (TAU) condition was selected to mirror the existing process in the military for identifying and encouraging treatment for personnel who screen positive for PTSD. | Behavioral: Treatment as Usual<br>* TAU will include a written referral list comprised of PTSD resources including information on in-person treatments, self-help, web-based and bibliotherapy options. At the completion of the study, participants in the TAU condition will be offered the MET intervention.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinician Administered PTSD Scale (CAPS) | The Clinician Administered PTSD Scale (CAPS) is a structured, clinician-administered interview that assesses the severity of each of the PTSD symptoms listed in Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and yields a clinical PTSD diagnosis and overall severity rating. The CAPS total severity rating ranges from 0-80, with higher scores indicating greater PTSD severity. | 1 months | 
| Treatment Utilization | The Treatment Utilization questionnaire asks about current and past use of different treatment services. Part 1: Participants are asked (yes/no) if they have ever participated in treatment or support for different concerns (i.e., depression, marital or family concerns, posttraumatic stress, smoking cessation, anger management, and drinking or drug use) and then asked to identify type of treatment or support (i.e., self help, group therapy, individual therapy, medication, inpatient/ residential program, and other) they received for any of the concerns they reported yes. Part 2: Participants are asked (yes/no/not applicable) if they have participated in treatment or support for any of the concerns reported in Part 1 in the past 3 months. Part 3: Participants are asked (yes/no) about their use of treatment and support resources used in the past 3 months for dealing with psychological or emotional concerns related to a traumatic event. | 3 months | 
| Treatment Reactions Scale | The Treatment Reactions Scale (TRS) is a 31-item measure that assesses the respondent's perceptions of treatment for mental and behavioral health. The TRS total score ranges from 31-155, with lower scores indicating more favorable reactions to treatment. The TRS consists of 5 subscales: Embarrassment/shame for seeking treatment (5 items, range 5-25; lower score indicates less embarrassment/shame for seeking treatment) Occupational/career impact of seeking treatment (4 items, range 4-20; lower score indicates less occupational/career impact of seeking treatment) Perceived debasement for receiving treatment (9 items, range 9-45; lower score indicates less perceived debasement for receiving treatment) Willingness to recommend treatment (7 items, range 7-35; lower score indicates more willingness to recommend treatment) Confidence in/belief in the efficacy of treatment (6 items, range 6-30; lower score indicates more confidence in/belief in the efficacy of treatment) | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Depression Module from the Patient Health Questionnaire (PHQ-9) | Measure that asks respondents to rate frequency of nine depressive symptoms over the past two weeks. | 2 weeks | 
| Daily Drinking Questionnaire | Measure that asks the respondent to think about a typical week and estimate the typical number of drinks he or she consumes each day of that week. | 1 week | 
| Alcohol Use Disorder Identification Test (AUDIT) | Measure that asks about the respondent's alcohol use. | 6 months |
