Recently, Dodge et al. (2024) published an article in American Psychologist offering recommendations to the mental health field for changing from an individual-level to a population-level focus. These recommendations included scaling up evidence-based programs, innovating and evaluating population-level interventions, and creating a primary system...
Background: As reported in this journal, Resick and colleagues (2023) investigated discrepancies between scores from two widely used PTSD measures: the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5; Weathers et al., 2013) and the PTSD Checklist for DSM-5 (PCL-5; Weathers et al., 2013), a clinician-rated structured interview and a self-rated q...
Importance
Test accuracy studies often use small datasets to simultaneously select an optimal cutoff score that maximizes test accuracy and generate accuracy estimates.
Objective
To evaluate the degree to which using data-driven methods to simultaneously select an optimal Patient Health Questionnaire-9 (PHQ-9) cutoff score and estimate accuracy yi...
We examined beliefs and practices regarding firearm assessment and lethal means safety counseling (LMSC) among U.S. Air Force (USAF) mental health providers (MHPs) and behavioral health technicians (BHTs). Data were collected from 204 USAF MHPs (74.0%; n = 151) and BHTs (26.0%; n = 53) via an anonymous, voluntary survey. A modest proportion indicat...
Background
The period after psychiatric hospital discharge is one of elevated risk for suicide‐related behaviors (SRBs). Post‐discharge clinical outreach, although potentially effective in preventing SRBs, would be more cost‐effective if targeted at high‐risk patients. To this end, a machine learning model was developed to predict post‐discharge su...
Posttraumatic stress disorder (PTSD) is a disabling condition that causes impairments in psychosocial and physical functioning. Prior research links PTSD to lower self-reported physical activity (PA) engagement. However, few studies have examined the impact of PTSD on objective measures of PA.
PURPOSE: To examine associations of objectively measur...
Importance
The suicide rate of military servicemembers increases sharply after returning to civilian life. Identifying high-risk servicemembers before they leave service could help target preventive interventions.
Objective
To develop a model based on administrative data for regular US Army soldiers that can predict suicides 1 to 120 months after...
At the 39th meeting of the International Society of Traumatic Stress Studies, three leading researchers and clinicians in technology‐enabled traumatic stress support were invited to reflect on their careers and contributions to the field. Dr. Brian P. Marx has led the development of large‐scale technologies to screen, assess, and treat traumatic st...
Administration mode of patient-reported outcome measures (PROMs) may influence responses. We assessed if Patient Health Questionnaire-9 (PHQ-9), Edinburgh Postnatal Depression Scale (EPDS) and Hospital Anxiety and Depression Scale – Depression subscale (HADS-D) item responses and scores were associated with administration mode. We compared (1) self...
Objective: To compare the course of change in individual posttraumatic stress disorder (PTSD) symptoms during prolonged exposure therapy (PE) and cognitive processing therapy (CPT). Method: We analyzed data from a previously published randomized clinical trial comparing PE and CPT among male and female U.S. military veterans with PTSD (Schnurr et a...
Objective
The present study examined the 20-year course of posttraumatic stress disorder (PTSD) in World Trade Center (WTC) responders to address four questions: (1) How stable are symptoms of PTSD? (2) What is the average symptom trajectory? (3) How much do responders differ from the average trend? (4) How quickly do PTSD symptoms improve or worse...
Efforts to develop an individualized treatment rule (ITR) to optimize major depressive disorder (MDD) treatment with antidepressant medication (ADM), psychotherapy, or combined ADM-psychotherapy have been hampered by small samples, small predictor sets, and suboptimal analysis methods. Analyses of large administrative databases designed to approxim...
This article provides an overview of written exposure therapy (WET), which is a brief treatment approach for posttraumatic stress disorder (PTSD). The development of the treatment is described and the research supporting its efficacy and effectiveness is discussed. To date, research has found WET to be an effective treatment approach for PTSD, havi...
Prior studies on individuals with posttraumatic stress disorder (PTSD) defined an adequate dose of psychotherapy as receiving at least nine sessions within a 15-week period. Yet, few studies have examined whether this definition of adequate dose is associated with meaningful change in PTSD symptoms over an extended period. To examine whether an ade...
We examined transdiagnostic and posttraumatic stress disorder (PTSD)–specific associations with multiple forms of trauma exposure within a nationwide U.S. sample ( N = 1,649, 50.0% female) of military veterans overselected for PTSD. A higher‐order Distress factor was estimated using PTSD, major depressive disorder (MDD), and generalized anxiety dis...
Posttraumatic stress disorder (PTSD) Criterion A, also known as the “stressor criterion,” has been a major source of debate ever since PTSD was added to the third edition of the Diagnostic and Statistical Manual for Mental Disorders ( DSM ) in 1980. Since then, the traumatic stress field has held an ongoing debate about how to best define Criterion...
We used item response theory (IRT) analysis to examine Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) item performance using data from three large samples of veterans (total N = 808) using both binary and ordinal rating methods. Relative to binary ratings, ordinal ratings provided good coverage from well below to well above average within eac...
Subthreshold posttraumatic stress disorder (PTSD) has long been recognized as an important construct that identifies a subgroup of individuals who report significant PTSD symptoms and associated disability but do not endorse enough symptoms to meet the criteria for a full PTSD diagnosis. Different investigators have defined subthreshold PTSD in var...
Importance
Psychiatric hospitalization is the standard of care for patients presenting to an emergency department (ED) or urgent care (UC) with high suicide risk. However, the effect of hospitalization in reducing subsequent suicidal behaviors is poorly understood and likely heterogeneous.
Objectives
To estimate the association of psychiatric hosp...
The PTSD Checklist for DSM-5 (PCL-5) is a measure of posttraumatic stress disorder (PTSD) symptom severity that is widely used for clinical and research purposes. Although previous work has examined metrics of minimal important difference (MID) of the PCL-5 in veteran samples, no work has identified PCL-5 MID metrics among adults in primary care in...
Objective: The construct of psychological resilience has received increasing attention in the mental health field. This article describes the development and initial validation of a novel self-report resilience scale, which addresses gaps in the resilience measurement literature by assessing thoughts and behaviors that help promote resilience rathe...
Importance:
Evidence-based treatments for posttraumatic stress disorder (PTSD) exist, but all require 8 to 15 sessions and thus are less likely to be completed than brief treatments. Written exposure therapy (WET) is a brief and efficacious treatment that has not been directly compared with prolonged exposure therapy (PE), a more time-intensive, e...
The course of posttraumatic stress disorder (PTSD) symptoms varies among veterans of war zones, but sources of variation in long-term symptom course remain poorly understood. Modeling of symptom growth trajectories facilitates the understanding of predictors of individual outcomes over time. Although growth mixture modeling (GMM) has been applied t...
Objective: In posttraumatic stress disorder (PTSD), the assumption of the equipotentiality of traumas ignores potentially unique contexts and consequences of different traumas. Accordingly, Stein et al. (2012) developed a reliable typing scheme in which assessors categorized descriptions of traumatic events into six “types”: life threat to self (LT...
Objective: Clinicians, patients, and researchers need benchmarks to index individual-level clinically significant change (CSC) to guide decision making and inferences about treatment efficacy. Yet, there is no consensus best practice for determining CSC for posttraumatic stress disorder (PTSD) treatments. We examined criterion-related validity of t...
Background
Risk of suicide-related behaviors is elevated among military personnel transitioning to civilian life. An earlier report showed that high-risk U.S. Army soldiers could be identified shortly before this transition with a machine learning model that included predictors from administrative systems, self-report surveys, and geospatial data....
Importance
The months after psychiatric hospital discharge are a time of high risk for suicide. Intensive postdischarge case management, although potentially effective in suicide prevention, is likely to be cost-effective only if targeted at high-risk patients. A previously developed machine learning (ML) model showed that postdischarge suicides ca...
We assessed the interrater reliability, convergent validity, and discriminant validity of the Self-Injurious Thoughts and Behaviors Interview-Short Form (SITBI-SF) in a sample of 1,944 active duty service members and veterans seeking services for posttraumatic stress disorder (PTSD) and related conditions. The SITBI-SF demonstrated high interrater...
Posttraumatic stress disorder (PTSD) changed substantially when Diagnostic and Statistical Manual of Mental Disorders transitioned from fourth ( DSM-IV) to fifth ( DSM-5) edition. Hoge et al. found that although diagnostic prevalence remained consistent across nomenclatures, diagnostic concordance was low (55%). Study goals were to examine both the...
Purpose
The course of posttraumatic stress disorder (PTSD) symptoms varies among veterans of warzones, but sources of variation in long-term course remain poorly understood. Modeling of symptom growth trajectories facilitates understanding predictors of individual outcomes over time. Although growth mixture modeling (GMM) has been applied to milita...
The co-occurrence of posttraumatic stress disorder (PTSD) and alcohol use disorder (AUD) is common following sexual assault and associated with more severe symptomology and increased likelihood of sexual revictimization. Integrated interventions aimed at reducing PTSD and AUD symptoms following recent sexual assault are needed and should address ba...
The coronavirus disease 2019 (COVID-19) pandemic has created a global health crisis, with disproportionate effects on vulnerable sociodemographic groups. Although the pandemic is showing potential to increase suicide ideation (SI), we know little about which sociodemographic characteristics or COVID-19 experiences are associated with SI. Our United...
Introduction
Active duty service members transitioning to civilian life can experience significant readjustment stressors. Over the past two decades of the United States’ longest sustained conflict, reducing transitioning veterans’ suicidal behavior and homelessness became national priorities. However, it remains a significant challenge to identify...
Recent‐era U.S. veterans are clinically complex, with a high prevalence of co‐occurring mild traumatic brain injury (mTBI), psychiatric conditions, and behavioral dysfunction. The current study examined the direct and indirect associations between mTBI and persistent neurobehavioral, psychiatric, and functional disability symptoms among recent‐era...
Objective
Suicidal intent is a risk factor for engagement in suicidal behavior, use of violent means, and suicide mortality. Yet, scarce research has examined factors associated with suicidal intent among U.S. military veterans, a population at high risk for suicide. This study examined vulnerability factors associated with suicidal intent in a po...
Objective: Greater duration of negative trauma-related beliefs may inhibit improvements in these cognitions during posttraumatic stress disorder (PTSD) treatment. The goal of the current study was to examine the impact of time since trauma on change in negative trauma-related beliefs during PTSD treatment. Method: A sample of 126 adults diagnosed w...
Each year, approximately 50,000 individuals in the United States and over 800,000 individuals worldwide die by suicide (Naghavi & the Global Burden of Disease Self-Harm Collaborators, 2019). Each person who dies by suicide leaves in their wake a network of individuals affected in some way by their death. For individuals connected to mental health s...
Background
The transition from military service to civilian life is a high-risk period for suicide attempts (SAs). Although stressful life events (SLEs) faced by transitioning soldiers are thought to be implicated, systematic prospective evidence is lacking.
Methods
Participants in the Army Study to Assess Risk and Resilience in Servicemembers (ST...
Researchers studying posttraumatic stress disorder (PTSD) often use diagnostic codes within electronic medical records (EMRs) to identify individuals with the disorder. This study evaluated the performance of algorithms for defining PTSD based on International Classification of Diseases (ICD) code use within EMR data. We used data from a registry o...
The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) versions of the Clinician-Administered PTSD Scale (CAPS-5) and PTSD Checklist (PCL-5) are widely used PTSD measures. Researchers and clinicians routinely use both measures in tandem to quantify symptom change, despite substantive instrumentation differences beyond admi...
Objectives:
Veterans who decline to provide information on their history of self-injurious thoughts and behaviors (SITBs) may be at elevated suicide risk. We examined associations between non-response to a question assessing lifetime SITBs and proxy variables of suicide risk.
Methods:
In this population-based cross-sectional study of 4069 US vet...
Prior research suggests that anhedonia symptoms related to posttraumatic stress disorder (PTSD; i.e., diminished interest, detachment from others, and difficulty experiencing positive emotions) are consistently associated with a higher degree of impairment in psychosocial functioning beyond that associated with other PTSD symptoms. Unfortunately, m...
Background
Network modeling has been applied in a range of trauma-exposed samples, yet results are limited by an over reliance on cross-sectional data. The current analyses used posttraumatic stress disorder (PTSD) symptom data collected over a 5-year period to estimate a more robust between-subject network and an associated symptom change network....
Suicide risk is elevated among military service members who recently transitioned to civilian life. Identifying high-risk service members before this transition could facilitate provision of targeted preventive interventions. We investigated the feasibility of doing this by attempting to develop a prediction model for self-reported suicide attempts...
Background: Posttraumatic stress disorder (PTSD) is associated with physical inactivity and cigarette smoking. However, little is known about the degree to which comorbid psychiatric conditions affect the odds of physical inactivity and smoking among individuals with PTSD. Objective: To examine associations between PTSD, comorbid psychiatric condit...
Objective: The US military veteran population is changing rapidly, and contemporary data on the prevalence of DSM-5 posttraumatic stress disorder (PTSD) are lacking. The DSM-5 clarified PTSD Criterion A to delineate direct and indirect trauma exposures, but effects on the conditional probability of PTSD and functional impairment remain unknown. The...
Objective: Psychiatric disorders increase risk for contracting coronavirus disease 2019 (COVID-19), but we know little about relationships between psychiatric symptoms and COVID-19 risky and protective behaviors. Posttraumatic stress disorder (PTSD) has been associated with increased propensity to engage in risky behaviors, but may also be associat...
Prior research indicates that veterans are interested in including family members in healthcare and that family-inclusive mental health treatment can improve treatment outcomes. Consequently, the Veterans Health Administration’s (VHA) directive require providers to offer family-inclusive mental health services to veterans. However, the extent to wh...
Importance:
Posttraumatic stress disorder (PTSD) is a prevalent and serious mental health problem. Although there are effective psychotherapies for PTSD, there is little information about their comparative effectiveness.
Objective:

Posttraumatic stress disorder (PTSD) is associated with increased health care costs; however, most studies exploring this association use PTSD diagnostic data in administrative records, which can contain inaccurate diagnostic information and be confounded by the quantity of service use. We used a diagnostic interview to determine PTSD diagnostic st...
Importance
Posttraumatic stress disorder (PTSD) occurs more commonly among military service members than among civilians; however, despite the availability of several evidence-based treatments, there is a need for more efficient evidence-based PTSD treatments to better address the needs of service members. Written exposure therapy is a brief PTSD i...
Background: Network modeling has been applied in a range of trauma exposed samples, yet results are limited by an over reliance on cross-sectional data. The current analyses used posttraumatic stress disorder (PTSD) symptom data collected over a five-year period to estimate a more robust between-subject network and an associated symptom change netw...
Bckground
Theories of suicide suggest that suicidal ideation (SI) results in part from difficulty imagining the future, which itself relies on the ability to remember the past. The present study examines multiple components of episodic future thinking and memory including event richness, which is commonly measured within the cognitive literature bu...
We calculated the reliable change index (RCI) and clinically significant change (CSC) values for two widely used measures of posttraumatic stress disorder (PTSD): The Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) and the PTSD Checklist for DSM-5 (PCL-5) and examined how symptom changes at these thresholds related to improvements in psychosoc...
Individual behaviors are critical for preventing the spread of coronavirus disease 2019 (COVID-19) infection. Given that both protective and risky behaviors influence risk of infection, it is critical that we understand how such behaviors cluster together and in whom. Using a data-driven approach, we identified clusters of COVID-19-related protecti...
Increasing concern about the mental health sequelae to the COVID-19 pandemic has prompted a surge in research and publications on the prevalence of posttraumatic stress disorder in general population samples in relation to the pandemic. We examined how posttraumatic stress disorder in the context of the COVID-19 pandemic has been studied to date an...
Studies of active duty service members have shown that military personnel who screen positive for posttraumatic stress disorder (PTSD) are more than twice as likely to make a suicide attempt. Evidence-based PTSD treatments can reduce suicidal ideation; however, it can be challenging to provide evidence-based, trauma-focused, PTSD treatment to high-...
Patients with posttraumatic stress disorder (PTSD) are at an elevated risk of suicide. For patients hospitalized for suicide risk, psychosocial treatment and stabilization are routinely offered; however, the availability of evidence-based, manualized therapeutic interventions for PTSD is sparse. Typically, the short duration of hospitalization make...
The STRONG STAR Consortium (South Texas Research Organizational Network Guiding Studies on Trauma and Resilience) and the Consortium to Alleviate PTSD are interdisciplinary and multi-institutional research consortia focused on the detection, diagnosis, prevention, and treatment of combat-related posttraumatic stress disorder (PTSD) and comorbid con...
Objective:
Sexual minority female (SMF) veterans experience unique stressors apart from their service in the military. In this study, we compared SMF and heterosexual female (HF) veterans' rates of deployment-related stressors (i.e., military sexual assault, combat exposure, and harassment), posttraumatic stress disorder (PTSD), and major depressi...
Objective: Cannabis use disorder (CUD) is the most common illicit substance use disorder in the United States and is especially prevalent among returning veterans. The long-term mental health correlates of CUD remain unknown, which is significant given recent shifts toward legalization and medicinal use of cannabis nationally.
Method: Using a gende...
Background
Worldwide, nearly 800,000 individuals die by suicide each year; however, longitudinal prediction of suicide attempts remains a major challenge within the field of psychiatry. The objective of the present research was to develop and evaluate an evidence-based suicide attempt risk checklist [i.e., the Durham Risk Score (DRS)] to aid clinic...
There are currently no validated pharmacotherapies for posttraumatic stress disorder (PTSD)-related insomnia. The purpose of the National Adaptive Trial for PTSD-Related Insomnia (NAP Study) is to efficiently compare to placebo the effects of three insomnia medications with different mechanisms of action that are already prescribed widely to vetera...
In the current study, we examined the degree to which sudden gains (large, rapid, and stable symptom reduction in a one-session interval) predicted treatment outcome in adults randomized to two different trauma-focused treatments. Adults diagnosed with PTSD were randomized to either written exposure therapy (WET; n = 63), a brief, exposure-based tr...
Background
Suicidal and nonsuicidal self-injurious thoughts and behaviors (SITBs) are major health concerns among military veterans yet little is known about the temporal relations among these outcomes. This study examined the temporal relations between suicidal and nonsuicidal SITBs among higher-risk veterans. Specifically, we identified when SITB...
The Depressive Symptom Index-Suicidality Subscale (DSI-SS) is a four-item self-report measure of suicidal ideation severity widely used across research and clinical contexts. However, the psychometric properties of the English-language version of the DSI-SS have not been extensively examined within a psychiatric sample, and important properties of...
Prior research suggests that a significant number of veterans with posttraumatic stress disorder (PTSD) do not have this diagnosis recognized in the electronic health record (EHR). Unfortunately, such diagnostic errors can lead to improper allocation of already scarce health care services and resources. In this study, we examined concordance betwee...
This study examined whether romantic relationship functioning was associated with mental health treatment utilization in male and female veterans. Veterans (N = 760) enrolled in a longitudinal registry completed self-report measures and a diagnostic interview for posttraumatic stress disorder (PTSD). Mental health treatment utilization data procure...
