Reactive aggression is posited to occur as a result of hypersensitivity to threat, whereas fearlessness may drive proactive aggression. This study aimed to test if physiological fear reactivity differentially relates to self-report reactive and proactive aggression using immersive virtual reality fear (VR) induction. We collected subjective fear ratings and sympathetic (SNS; skin conductance) and parasympathetic (PNS; respiratory sinus arrhythmia) nervous system reactivity during an interactive VR horror video.

Previous research has found that personality factors may be relevant predictors of post-deployment drinking, yet results have been inconsistent and may be influenced by the selection of drinking outcome. This study aimed to examine relations between PTSD, negative urgency, and the five factor models of personality with multiple alcohol consumption patterns, including maximum drinks in a day, number of binge drinking episodes, at-risk drinking, and average weekly drinks in a sample of 397 Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn (OEF/OIF/OND) Veterans.

Emerging theory suggests that treating PTSD may not disrupt an association between negative affect and alcohol craving, which underlies negative reinforcement drinking. The goal of the current study was to determine the respective influences of PTSD symptoms, coping motives, and negative affect on trauma and alcohol cue reactivity to inform theoretical models of co-occurring PTSD and AUD.

Psychopathy has been long associated with anxiety, and anxiety has been argued to play an important role in psychopathy-related behaviors, such as aggression. However, these associations have not yet been explored in Not Guilty by Reason of Insanity (NGRI) Acquittees. The goals of the present study were to test the correlations between the 4-facet psychopathy construct and anxiety, and to assess whether anxiety mediates the association between psychopathy and aggression.

The present study aimed to test for sex differences in the relation between the four-facet model of psychopathy and intelligence, and to assess whether fluid intelligence moderates the link between psychopathy and aggression. In a community sample of men ( = 356) and women ( = 196), we assessed psychopathy using the Psychopathy Checklist: Screening Version (PCL:SV), fluid intelligence using the Raven's Progressive Matrices, and types of aggression using the Aggression Questionnaire (AQ).

Introduction: A strong association between posttraumatic stress disorder (PTSD) and problematic alcohol use has been demonstrated among Veteran populations exposed to combat trauma. Several traits, such as higher levels of risk-taking propensity (RTP) and impulsivity (e.g.

However, little is known about potential etiological factors underlying the development of perceived (i.e.
View Article and Find Full Text PDFObjective: Distress tolerance (DT; the perceived or actual ability to withstand negative internal states) has emerged as a promising transdiagnostic risk factor in clinically severe populations. However, little is known about etiological factors associated with the development of DT. We hypothesized that greater levels of childhood trauma would be associated with lower perceived and behavioral DT, beyond theoretically relevant covariates.

However, it is unclear which individuals experiencing PTSD symptoms are at greatest risk for alcohol-use problems following trauma exposure. Individuals endorsing high anxiety sensitivity, which is the fear of anxiety and related sensations, may be particularly motivated to use alcohol to cope with PTSD symptoms.

However, there is a lack of research investigating relations between, and correlates of, trauma and cannabis phenotypes in epidemiologic samples. The current study examined associations between trauma (i.
