ABSTRACT: The Detailed Assessment of Posttraumatic Stress (DAPS; Briere, 2001) is a comprehensive questionnaire that assesses posttraumatic stress disorder (PTSD) diagnostic criteria as well as peritraumatic responses and associated problems such as dissociation, suicidality, and substance abuse. DAPS scores have demonstrated excellent reliability, validity, and clinical utility, performing as well or better than leading PTSD questionnaires. The present study was an initial psychometric evaluation of the unreleased DAPS (DAPS-2), revised for

ABSTRACT: The Military Suicide Research Consortium (MSRC) developed a 57-item questionnaire assessing suicide risk factors, referred to as the Common Data Elements (CDEs), in order to facilitate data sharing and improve collaboration across independent studies. All studies funded by MSRC are required to include the CDEs in their assessment protocol. The CDEs include shortened measures of the following: current and past suicide risk, lethality and intent of past suicide attempts, hopelessness, thwarted belongingness, anxiety sensitivity, posttraumatic stress disorder symptoms, traumatic brain injury, insomnia, and alcohol abuse. This study aimed to evaluate the psychometric properties of the CDE items drawn from empirically validated measures. Exploratory factor analysis was used to examine the overall structure of the CDE items, and confirmatory factor analyses were used to evaluate the distinct properties of each scale. Internal consistencies of the CDE scales and correlations with full measures were also examined. Merged data from 3,140 participants (81.0% military service members, 75.6% male) across 19 MSRC-funded studies were used in analyses. Results indicated that all measures exhibited adequate internal consistency, and all CDE shortened measures were significantly correlated with the corresponding full measures with moderate to strong effect sizes. Factor analyses indicated that the shortened CDE measures performed well in comparison with the full measures. Overall, our findings suggest that the CDEs are not only brief but also provide psychometrically valid scores when assessing suicide risk and related factors that may be used in future research.

3 Article Posttraumatic Stress Disorder Symptom Clusters and Acquired Capability for Suicide: A Reexamination Using DSM-5 Criteria. 2018

Spitzer, Elizabeth G / Zuromski, Kelly L / Davis, Margaret T / Witte, Tracy K / Weathers, Frank. ·Department of Psychology, Auburn University, Auburn, AL, USA. ·Suicide Life Threat Behav · Pubmed #28261858.

ABSTRACT: This study used the interpersonal-psychological theory of suicide to explore the relationships among DSM-5 posttraumatic stress disorder (PTSD) symptom clusters derived from the six-factor anhedonia model and facets of acquired capability for suicide (ACS). In a sample of 373 trauma-exposed undergraduates, most PTSD symptom clusters were negatively associated with facets of ACS in bivariate correlations, but the anhedonia cluster was positively associated with ACS in regression models. Structure coefficients and commonality analysis indicated that anhedonia served as a suppressor variable for the other symptom clusters. Our findings further elucidate the complex relationship between specific PTSD symptom clusters and ACS.

4 Article The Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5): Development and Initial Psychometric Evaluation. 2015

Blevins, Christy A / Weathers, Frank W / Davis, Margaret T / Witte, Tracy K / Domino, Jessica L. ·VA Portland Health Care System, Portland, Oregon, USA. · Department of Psychology, Auburn University, Auburn, Alabama, USA. · South Texas Veterans Health Care System, San Antonio, Texas, USA. ·J Trauma Stress · Pubmed #26606250.

ABSTRACT: The Posttraumatic Stress Disorder Checklist (PCL) is a widely used DSM-correspondent self-report measure of PTSD symptoms. The PCL was recently revised to reflect DSM-5 changes to the PTSD criteria. In this article, the authors describe the development and initial psychometric evaluation of the PCL for DSM-5 (PCL-5). Psychometric properties of the PCL-5 were examined in 2 studies involving trauma-exposed college students. In Study 1 (N = 278), PCL-5 scores exhibited strong internal consistency (α = .94), test-retest reliability (r = .82), and convergent (rs = .74 to .85) and discriminant (rs = .31 to .60) validity. In addition, confirmatory factor analyses indicated adequate fit with the DSM-5 4-factor model, χ2 (164) = 455.83, p < .001, standardized root mean square residual (SRMR) = .07, root mean squared error of approximation (RMSEA) = .08, comparative fit index (CFI) = .86, and Tucker-Lewis index (TLI) = .84, and superior fit with recently proposed 6-factor, χ2 (164) = 318.37, p < .001, SRMR = .05, RMSEA = .06, CFI = .92, and TLI = .90, and 7-factor, χ2 (164) = 291.32, p < .001, SRMR = .05, RMSEA = .06, CFI = .93, and TLI = .91, models. In Study 2 (N = 558), PCL-5 scores demonstrated similarly strong reliability and validity. Overall, results indicate that the PCL-5 is a psychometrically sound measure of PTSD symptoms. Implications for use of the PCL-5 in a variety of assessment contexts are discussed.

5 Article Item order effects in the evaluation of posttraumatic stress disorder symptom structure. 2015

Witte, Tracy K / Domino, Jessica L / Weathers, Frank W. ·Department of Psychology, Auburn University. ·Psychol Assess · Pubmed #25688561.

ABSTRACT: Factor analytic research has demonstrated consistently that the 3-factor DSM-IV model of posttraumatic stress disorder (PTSD) symptom structure provides a poorer fit than alternative 4- and 5-factor models. In the current study we examined whether order of item presentation accounts for these findings. In a large sample (N = 1,311) of trauma-exposed undergraduates we conducted a series of confirmatory factor analyses using the PTSD Checklist and Posttraumatic Stress Diagnostic Scale, which present symptom items in the same order as DSM-IV, and the Detailed Assessment of Posttraumatic Stress, which presents items in a different order. Across all 3 measures the 3-factor DSM-IV model provided a relatively worse fit and the 5-factor dysphoric arousal model provided a relatively better fit compared with other tested models. We also examined the distinctiveness of 2 pairs of symptom clusters that appear in the dysphoric arousal model--avoidance versus numbing and dysphoric arousal versus anxious arousal--by comparing their patterns of associations with external correlates. Avoidance and numbing demonstrated differential associations with external correlates, as did dysphoric arousal and anxious arousal. Taken together, results indicate that order effects are unlikely to account for differences in relative fit between leading models of PTSD symptom structure. We discuss the need for future research in this area, especially studies designed to evaluate order effects more directly.

6 Article Dissociation and posttraumatic stress disorder: a latent profile analysis. 2014

Blevins, Christy A / Weathers, Frank W / Witte, Tracy K. ·Department of Psychology, Auburn University, Auburn, Alabama, USA. ·J Trauma Stress · Pubmed #25069601.

ABSTRACT: The fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, ) contains a dissociative subtype for posttraumatic stress disorder (PTSD) characterized by significant depersonalization and derealization. In this study the PTSD dissociative subtype was examined using latent profile analysis in a sample of 541 trauma-exposed college students. Items from the PTSD Checklist and Multiscale Dissociation Inventory were used as latent class indicators. Results supported a 3-class solution including a well-adjusted class, a PTSD class, and a PTSD/dissociative class characterized by elevated symptoms of PTSD, depersonalization, and derealization. Significant class differences were found on a number of measures of related psychopathology with Cohen's d effect size estimates ranging from 0.04 to 1.86. Diagnostic and treatment implications regarding the dissociative subtype are discussed.

7 Article PTSD symptom clusters are differentially associated with components of the acquired capability for suicide. 2014

Zuromski, Kelly L / Davis, Margaret T / Witte, Tracy K / Weathers, Frank / Blevins, Christy. ·Department of Psychology, Auburn University, Auburn, AL, USA. ·Suicide Life Threat Behav · Pubmed #24796870.

ABSTRACT: Previous research has established the link between posttraumatic stress disorder (PTSD) and suicidal behavior. In the current study, constructs proposed to explain this relationship were examined, applying the framework of the interpersonal-psychological theory of suicide (IPTS). Relationships between acquired capability for suicide (ACS; i.e., fearlessness about death [FAD] and pain tolerance) and specific PTSD symptom clusters were explored. In a sample of 334 trauma-exposed undergraduates, anxious arousal and FAD were negatively associated, and numbing and pain tolerance were positively associated. Results establish a foundation for investigating the role of ACS in understanding observed relationships between suicidal behavior and PTSD symptoms.
