Consensual facet structures help to unify a highly fractured personality literature, but mask information obtained from unique personality facets assessed by individual personality inventories. The current study identifies the consensual and unique facets of neuroticism, conscientiousness, and agreeableness based on analyses of five widely used personality inventories (Disinhibition Inventory-I [DIS-I], Faceted Inventory for the Five-Factor model [FI-FFM], HEXACO Personality Inventory-Revised [HEXACO-PI-R], NEO Personality Inventory-3 [NEO-PI-3], and Temperament and Affectivity Inventory [TAI]) in a community sample ( = 440). Factor analyses revealed that neuroticism consisted of three consensual facets (distress/depression, anger, and sentimental anxiety) and four unique facets (shyness, regret/self-doubt, lassitude, and distractibility); conscientiousness consisted solely of four consensual facets (achievement striving, order, attentiveness, and responsibility); and agreeableness consisted solely of four consensual facets (prosociality, anger, venturesomeness, and trust).

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 status and examined associations between PTSD symptom severity and health care costs and utilization, extracted from Veteran Health Administration (VHA) administrative databases. Using a nationwide longitudinal sample of U.

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 between PTSD diagnoses in the Veterans Affairs (VA) EHR and PTSD diagnoses based on a semistructured diagnostic interview and mental health service use in a sample of veterans ( = 1,299) enrolled in VA healthcare.

: Posttraumatic stress disorder (PTSD) is associated with premature onset of chronic health conditions such as cardiovascular disease. Diet and exercise are behavioural contributors to physical health, and research suggests they are influenced by psychiatric symptoms, including PTSD. : The aim of this study was to examine longitudinal associations between PTSD and exercise and diet quality and to test if emotion regulation strategies contribute to the link between PTSD and these health behaviours.

Background: Research suggests that re-experiencing and avoidance are "core" PTSD symptoms, but there has been little research explicating their unique connections to psychopathology other than internalizing conditions such as depression and anxiety. We aim to unpack symptom heterogeneity within PTSD by exploring associations between re-experiencing and avoidance clusters and major psychopathology domains in a dimensional metastructural framework (e.g.

This study examined the psychometric properties of a widely used measure of symptom exaggeration, the Miller Forensic Assessment of Symptoms Test (M-FAST, Miller, 2001), in a sample of 209 (83.7% male) trauma-exposed veterans (57.9% probable current posttraumatic stress disorder; PTSD).

We examined the validity of self-report measures of narcissism and mania by relating them to interview-based ratings of psychopathology. Narcissism scales were taken from the Narcissistic Personality Inventory (NPI), the Personality Diagnostic Questionnaire-4+, and the Short Dark Triad. Mania measures included the Altman Self-Rated Mania Scale (ASRM) and scales taken from the Hypomanic Personality Scale (HPS) and Expanded Version of the Inventory of Depression and Anxiety Symptoms.

Extraversion shows both negative and positive associations with psychopathology. Previous work in this area has focused largely on either a broad higher order extraversion domain score or on specific lower-order extraversion facets. The goal of this study was to explicate how two intermediate of the trait- and -relate to psychopathology.

Prospective memory (PM) - or memory for tasks to be completed in the future - is essential for daily functioning. Although depression and anxiety have been shown to impair PM performance, few studies have explored the relative contributions of different symptom domains. Here, we examined the relation between anxiety, depression, negative mood, and PM performance using the tripartite model.

Although personality and emotion regulation abilities appear to overlap considerably, few studies have adopted an integrative approach by examining personality and emotion regulation together. Therefore, it is unclear how much incremental power emotion regulation demonstrates in predicting psychopathology beyond personality traits, and vice versa. Results from a community sample characterized by high levels of psychopathology (N = 299) indicated that personality and emotion regulation represent strongly related but distinguishable constructs, with both showing incremental power beyond the other in many cases in predicting self-reported and interview-rated psychopathology.

The primary goal of this study was to explicate the construct validity of the Narcissistic Personality Inventory (NPI) and the Hypomanic Personality Scale (HPS) by examining their relations both to each other and to measures of personality and psychopathology in a community sample ( N = 255). Structural evidence indicates that the NPI is defined by Leadership/Authority, Grandiose Exhibitionism, and Entitlement/Exploitativeness factors, whereas the HPS is characterized by specific dimensions reflecting Social Vitality, Mood Volatility, and Excitement. Our results establish that (a) factor-based subscales from these instruments display divergent patterns of relations that are obscured when relying exclusively on total scores and (b) some NPI and HPS subscales more clearly tap content specifically relevant to narcissism and mania, respectively, than others.

The goal of this study was to explicate how the lower order facets of extraversion are related to psychopathology. We used a "bottom-up" approach in which specific extraversion scales from 3 comprehensive personality inventories were used to model these facets as latent factors. We collected both self-report and interview measures of a broad range of psychopathology from a large community sample.

The current study examined the bivariate and multivariate associations of personality with Body Mass Index (BMI) and several eating behavior inventories, focusing on facets of Neuroticism, Conscientiousness, and Impulsivity. Simultaneous multiple regressions showed that the facets Traditionalism, Urgency, and low Vulnerability were significant predictors of BMI. A factor analysis of the eating behavior scales revealed two dimensions: (a) Food and Body Preoccupation and (b) Cued Eating; Neuroticism, low Conscientiousness, and Perfectionism were significant predictors of both eating behavior factors.
