Recently, Dodge et al. (2024) published an article in 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 of care to promote mental health and well-being.

Article Synopsis
  • The study investigates how using small datasets to select an optimal cutoff score for the Patient Health Questionnaire-9 (PHQ-9) can lead to inaccurate results.
  • Researchers evaluated whether data-driven methods for cutoff selection resulted in scores that were significantly different from the true population optimal score and if these methods produced biased accuracy estimates.
  • Findings showed that many small studies frequently failed to identify the correct optimal cutoff score, particularly in smaller samples, leading to an overestimation of test sensitivity.

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 questionnaire, respectively.

Article Synopsis
  • * The prevalence of lifetime full PTSD is reported at 8.4%, while subthreshold PTSD is at 3.9%, with both conditions linked to various psychiatric disorders and clinical issues.
  • * Veterans with subthreshold PTSD experience significant reductions in mental, psychosocial, and cognitive functioning, indicating the need for targeted identification and treatment to improve their overall well-being.

Although there are effective psychotherapies available for posttraumatic stress disorder (PTSD), brief treatments for PTSD are needed to expand the reach of treatment. Written exposure therapy (WET) is a brief treatment that has the potential to fill an important need in PTSD treatment and has a rapidly expanding evidence base to support its use. In this paper we provide information on how WET was developed, and we present proposed underlying mechanisms of the treatment and evidence supporting the underlying mechanism.

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.

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 approximate experiments followed iteratively by pragmatic trials hold promise for resolving these problems. The current report presents a proof-of-concept study using electronic health records (EHR) of n = 43,470 outpatients beginning MDD treatment in Veterans Health Administration Primary Care Mental Health Integration (PC-MHI) clinics, which offer access not only to ADMs but also psychotherapy and combined ADM-psychotherapy.

Background: With few exceptions, previously conducted research on hazardous drinking among Veterans has employed samples in which the majority of participants identify as male. In addition, past studies have solely focused on alcohol consumption, rather than associated risk for dependence. In this study, we expanded upon the extant literature by investigating sex differences in trajectories and predictors of change in alcohol consumption and dependence risk among post-9/11 Veterans.

Article Synopsis
  • This study creates a method to identify Army transitioning service members (TSMs) most at risk of becoming homeless to implement preventive measures.
  • Using data from 4,790 soldiers and two machine learning models, the research predicts homelessness risk based on available administrative and self-reported data.
  • The findings show that targeted machine learning approaches can effectively identify high-risk individuals for outreach, significantly aiding in homelessness prevention efforts.

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 adequate dose of individual or group psychotherapy was associated with PTSD symptom improvement, we identified mental health outpatient visits in the electronic medical record for a cohort of veterans enrolled in Veterans Health Administration (VHA) services ( = 1,649) across 5 years.

Fibers made from biopolymers are one solution for conserving both resources and the environment. However, these fibers currently have limited strengths, which limit their use for textile applications. In this paper, a biopolymer stereocomplex poly(-lactide) (scPLA) formation on a technical scale of high-molecular-weight poly(D-lactide) (PDLA) and poly(L-lactide) (PLLA) is presented.

Introduction: Posttraumatic stress disorder (PTSD) results in substantial costs to society. Prevalence of PTSD among adults is high, especially among those presenting to primary care settings. Evidence-based psychotherapies (EBPs) for PTSD are available but dissemination and implementation within primary care settings is challenging.

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 A and the events that it covers. Because of the COVID-19 pandemic and recent race-based incidents, the Criterion A debate has been reinvigorated.

We used item response theory (IRT) analysis to examine Clinician-Administered PTSD Scale for (CAPS-5) item performance using data from three large samples of veterans (total = 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 each symptom cluster. However, coverage varied by cluster, and item difficulties were unevenly distributed within each cluster, with numerous instances of redundancy.

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 various ways, making it difficult to interpret findings across studies. To address this problem, we systematically compared individuals who met criteria for nine different subthreshold PTSD definitions with individuals diagnosed with either full PTSD or no PTSD (i.

Article Synopsis
  • - The PTSD Checklist for DSM-5 (PCL-5) is a tool used to assess the severity of PTSD symptoms, but its minimal important difference (MID) metrics had not been studied in primary care settings until now.
  • - A study involving 971 primary care patients who screened positive for PTSD found strong test-retest reliability for the PCL-5 scores, indicating consistent measurement over time.
  • - The estimated MID for the PCL-5 change scores ranges from 9 to 12, suggesting that changes within this range reflect significant improvements in PTSD symptoms, while scores of 5 or less may not indicate meaningful change.
