Development and evaluation of a centralized assessment hub for the clinician-administered PTSD Scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (Caps-5)
Our Clinician-Administered PTSD Scale for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition training protocol was used successfully in the largest PTSD clinical trial to date. The use of a centralized assessment hub ensured highly accurate assessment that likely could not have been achieved using site-based raters across multiple sites.

Evaluating the Effectiveness of Safety Plans for Mitigating Suicide Risk in Two Samples of Psychiatrically Hospitalized Military Veterans
Veterans health administration leads the way in population mental health science
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 of care to promote mental health and well-being. For the past 2 decades, the Veterans Health Adminis…
Development and initial validation of the Mount Sinai Resilience Scale
Collectively, the results of this study provide initial support for the convergent and discriminant validity of the MSRS and describe its factor structure. (PsycInfo Database Record (c) 2024 APA, all rights reserved)
An examination of the criterion-related validity of varying methods of indexing clinically significant change in posttraumatic stress disorder treatment
The J&T methodology for indexing CSC in PTSD symptoms has criterion-related validity, and a norm-referenced benchmark appears to be the most potent. However, the norm-referenced parameters may be overly specific, potentially leading to an underestimate of improvement. Research is needed to test the generalizability of these results.

DSM-5 criterion-a-based trauma types in service members and veterans seeking treatment for posttraumatic stress disorder
Because of discrepancies between participant and assessor typologies, clinical researchers should use participants' ratings, and these should trump assessor judgment. Differences in pretreatment behavioral and mental health problems across some participant-endorsed trauma types partially support the validity of the participant ratings.

The effect of time since index trauma on trauma-related beliefs
These results indicate that trauma-focused therapies become less potent in reducing trauma-related beliefs as time progresses since trauma exposure, particularly in CPT, for beliefs about the world. Results indicate PTSD treatment should be provided in closer proximity to trauma exposure before negative trauma-related beliefs become inflexible.

The impact of deployment-related stressors on the development of PTSD and depression among sexual minority and heterosexual female veterans
SMF veterans may have unique stressors driving their development of MDD and PTSD. Understanding how different military stressors may confer risk for SMF veterans versus HF veterans is necessary to provide informed and sensitive clinical care to SMF veterans.

Longitudinal change in self-reported peritraumatic dissociation during and after a course of posttraumatic stress disorder treatment
Objective: Peritraumatic dissociation, a dissociative reaction that occurs at the time of a traumatic event, has been established as a strong risk factor for posttraumatic stress disorder (PTSD). However, self-reported peritraumatic dissociation is typically assessed months or years after trauma exposure and may be influenced by current distress levels and other factors. Method: We examined the temporal stability of scores on the Peritraumatic Di…
Virtual mental health care in the Veterans Health Administration’s immediate response to coronavirus disease-19
The coronavirus disease 2019 (COVID-19) pandemic has increased the need for psychological care in the global population and has created new barriers to accessing services. Hospitals, mental health facilities, and other clinics face the challenge of providing continued care to a population that is under severe stress, while minimizing in-person visits that risk spreading the virus. The Veterans Health Administration (VHA) is the largest integrated…

The Clinician-Administered PTSD Scale for DSM–5 (Caps-5)
The Clinician-Administered PTSD Scale (CAPS) is an extensively validated and widely used structured diagnostic interview for posttraumatic stress disorder (PTSD). The CAPS was recently revised to correspond with PTSD criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). This article describes the development of the CAPS for DSM-5 (CAPS-5) and presents the result…
Association between perceptions of military service and mental health problems in a nationally representative sample of United States military veterans
Taken together, results of this study suggest that perceptions of military service are associated with suicidal ideation and other mental health conditions. In addition, assessing veterans' perceptions of their service could be used as a method to identify possible at-risk veterans who may benefit from mental health services and resources.

Investigating the Aftermath of Terror
Acts of terrorism are becoming increasingly common throughout the world. These events represent a significant public health concern given the associated health consequences. Although it is clear that terrorist attacks have mental and physical health sequelae, the exact nature and prevalence of these consequences are unclear. Epidemiological research can play an important role in better understanding the mental and physical impact of terrorist att…
The effect of enemy combat tactics on PTSD prevalence rates
The nature of combat (specifically, asymmetric enemy tactics) may be a risk factor for the development of PTSD among males. Factors other than enemy tactics may be more important to the development of PTSD among females. (PsycINFO Database Record
Examining trauma and posttraumatic stress disorder symptoms in court-mandated intimate partner violence perpetrators
There is a dearth of empirical literature characterizing the various forms of trauma experienced by men court mandated to intervention for intimate partner violence (IPV) perpetration. We investigated the potentially traumatic events (PTEs) experienced by men (N = 217) court mandated to enroll in a 41-week group IPV perpetrator program, as well as the relationships between PTEs, posttraumatic stress disorder (PTSD) symptoms, and IPV. Findings ind…

Victim–offender relationship status moderates the relationships of peritraumatic emotional responses, active resistance, and posttraumatic stress symptomatology in female rape survivors
This study examined whether the level of victim-offender relationship (VOR) moderated the relationship between peritraumatic fear and active resistance as well as the relationship between peritraumatic fear and posttraumatic stress symptom severity in a community sample of female rape survivors. One hundred thirty-five participants were interviewed about their emotional and behavioral responses during the rape and assessed for posttraumatic stres…
PTSD symptoms among male Vietnam veterans
The present study examined reported rates of specific posttraumatic stress disorder (PTSD) symptoms in a veteran sample and the extent to which specific symptoms predicted PTSD diagnostic status. A sample of 1325 unmedicated male Vietnam veterans were interviewed using the Structured Clinical Interview for the Diagnostic and Statistical Manual, 3rd edition revised (DSM–III–R) by doctoral-level clinicians. Of the total sample, 798 met diagnostic c…

The importance of the peritraumatic experience in defining traumatic stress
In the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev., DSM-IV-TR; American Psychiatric Association, 2000), posttraumatic stress disorder (PTSD) Criterion A2 stipulates that an individual must experience intense fear, helplessness, or horror during an event that threatened the life or physical integrity of oneself or others to be eligible for the PTSD diagnosis. In considering this criterion, we describe its origins, rev…
Psychological Outcomes Among Lesbian Sexual Assault Survivors
This study explored the relations among internalized homophobia (IH), experiential avoidance, and psychological symptom severity in a community sample of 72 lesbian sexual assault survivors. Results indicated that IH is associated with both experiential avoidance and posttraumatic stress disorder (PTSD) symptom severity. In addition, experiential avoidance is related to both PTSD and depression symptom severity. Finally, experiential avoidance co…
Females' Perception of Date Rape

METHODS: Male (n = 48) and female (n = 46) college students were assigned to either a written disclosure condition or a control writing condition. Participants in each condition wrote on 3 consecutive days for 20 minutes each session. Heart rate was recorded during each writing session and the narratives wer…
The Relationships Among Risk Recognition, Autonomic and Self-Reported Arousal, and Posttraumatic Stress Symptomatology in Acknowledged and Unacknowledged Victims of Sexual Assault
Objective: This study examined differences among acknowledged sexual assault victims, unacknowledged sexual assault victims, and nonvictims in risk recognition and its psychophysiological correlates. Methods: Acknowledged and unacknowledged victims of sexual assault and nonvictims (n = 97) listened to a hypothetical date rape interaction and were asked to indicate the point at which the man had become sexually inappropriate. Self-report and physi…
The moderating effects of stimulus valence and arousal on memory suppression
This study examined the separate and combined effects of stimulus valence and arousal on retrieval inhibition. Participants performed Anderson and Green's (2001) memory suppression task with stimuli varying across dimensions of valence and arousal. Memory was tested through free and cued recall as well as speeded recognition. Results showed that both stimulus valence and arousal influenced the extent to which participants successfully inhibited r…
Expressive writing buffers against maladaptive rumination
This study examined whether ruminative style moderated the effects of expressive writing. Sixty-nine participants were assessed for ruminative style and depression symptoms at the beginning of their 1st college semester. Participants were then randomized to either an expressive writing or a control writing condition. Changes in depression symptoms were assessed 2, 4, and 6 months later. Results showed that a brooding ruminative style moderated th…

The influence of externalizing comorbidity on psychophysiological reactivity among veterans with posttraumatic stress disorder
Although most individuals with posttraumatic stress disorder (PTSD) demonstrate heightened physiological reactivity to trauma-related cues, many of these individuals do not. The presence of comorbid externalizing disorders is a potential explanation for this inconsistency. This study investigated the psychophysiological reactions to both standardized and idiographic trauma-related cues among male Vietnam Veterans with PTSD only, PTSD and a comorb…
