The novel frontal alpha asymmetry factor and its association with depression, anxiety, and personality traits.

Frontal alpha asymmetry (FAA) is widely examined in EEG research, yet a procedural consensus on its assessment is lacking. In this study, we tested a latent factorial approach to measure FAA. We assessed resting-state FAA at broad, low, and high alpha bands (8-13; 8-10.

Does Machiavellianism meaningfully differ from psychopathy? It depends.

Machiavellianism is a personality construct characterized by cynicism, callousness, and skillful manipulation of others to achieve personal gains. We review the Machiavellianism literature with a particular focus on its measurement alongside narcissism and psychopathy in the so-called "Dark Triad" (DT). We discuss criticisms of Machiavellianism on the grounds of insufficient construct validity as well as its virtual indistinguishability from psychopathy when assessed by commonly used instruments.

Personality disorders as predictors of intimate partner violence: A meta-analysis.

Despite years of research demonstrating a relation between personality pathology and intimate partner violence (IPV), no meta-analysis has been published examining how well, or poorly, all ten personality disorders (PDs) predict IPV perpetration or victimization, nor has any meta-analysis examined these relations across types of IPV. Therefore, the present study was undertaken to synthesize existing research on the effects of all ten PDs, as well as psychopathy and global PD symptoms, on physical, psychological, and sexual IPV perpetration and victimization. An initial search in PsycINFO, PubMed, and Sociological Abstracts yielded 3988 results.

Development and Validation of the Super-Short Form of the Five Factor Machiavellianism Inventory (FFMI-SSF).

Previous findings have showed that existing measures of Machiavellianism often fail to distinguish Machiavellianism from another construct in the Dark Triad (i.e., psychopathy) and do not align with theoretical descriptions.

Untangling the Relation Between Narcissistic Traits and Behavioral Aggression Following Provocation Using an FFM Framework.

Work on narcissism has identified two variants: grandiose and vulnerable. The variants share an antagonistic core, but differ in neuroticism and extraversion. The current study explored how the variants relate to behavioral aggression following provocation.

The Importance of Antagonism: Explaining Similarities and Differences in Psychopathy and Narcissism's Relations With Aggression and Externalizing Outcomes.

Psychopathy and narcissism are multidimensional constructs with substantial overlap. Low agreeableness (i.e.

Exploring Gender Differences in Machiavellianism Using a Measurement Invariance Approach.

Research suggests that men and women differ on mean levels of Dark Triad personality constructs such as Machiavellianism, but few studies have investigated whether or not these differences are due to actual latent trait differences or bias in measurement. Further, recent research suggests important challenges associated with existing measures of MACH in terms of overlap with psychopathy and matching expert descriptions. The present study took a recently developed measure of Machiavellianism (the Five Factor Machiavellianism Inventory; FFMI), based on the five-factor model, and examined its invariance across gender.

Examining the factor structure and validity of the Triarchic Model of Psychopathy across measures.

The triarchic model of psychopathy proposes 3 distinct trait domains underlying psychopathy: boldness, meanness, and disinhibition. The original (and most widely used) measure developed from this model is the Triarchic Psychopathy Measure (TriPM), which yields a total psychopathy score as well as scores on each of the 3 domains. Recently, researchers have derived several alternative measures from other inventories to assess these 3 domains; however, the purported underlying 3-factor structure of the alternative scales has been relatively untested.

The "core" of the dark triad: A test of competing hypotheses.

As research on the dark triad (DT; the interrelated constructs of Machiavellianism, narcissism, and psychopathy) has accumulated, a subset of this research has focused on explicating what traits may account for the overlap among the DT members. Various candidate traits have been investigated, with evidence supporting several of them, including antagonism (vs. agreeableness), honesty-humility, and callousness and interpersonal manipulation (the latter 2 as a set).

Using item-level analyses to better understand the consequences of partialing procedures: An example using the Dark Triad.

Objective: Partialing procedures are frequently used in psychological research. The present study sought to further explore the consequences of partialing, focusing on the replicability of partialing-based results.

Method: We used popular measures of the Dark Triad (DT; Machiavellianism, narcissism, and psychopathy) to explore the replicability of partialing procedures.

Using Bayesian methods to update and expand the meta-analytic evidence of the five-factor model's relation to antisocial behavior.

The Five Factor Model (FFM) of personality is the dominant hierarchical model of personality. Previous work has demonstrated the importance of the FFM domains and facets in understanding a variety of antisocial behaviors ranging from non-violent antisocial behavior to a variety of aggression outcomes. The aim of the present meta-analysis was to quantitatively summarize the empirical work that has examined these relations, as well as update and expand previous work in this area using Bayesian meta-analytic methods.

Development and preliminary validation of a five factor model measure of Machiavellianism.

Machiavellianism is characterized by planfulness, the ability to delay gratification, and interpersonal antagonism (i.e., manipulativeness and callousness).

Using Dominance Analysis to Decompose Narcissism and Its Relation to Aggression and Externalizing Outcomes.

Research on narcissism has shown it to be multidimensional construct. As such, the relations the larger construct bear with certain outcomes may mask heterogeneity apparent at the more basic trait level. This article used the Five Factor Narcissism Inventory, a Five-Factor Model-based measure of narcissism that allows for multiple levels of analysis, to examine the relative importance of narcissistic traits in relation to aggression, externalizing behavior, and self-esteem outcomes in two independent samples.

Differences among dark triad components: A meta-analytic investigation.

Since its emergence 14 years ago the dark triad (DT), composed of narcissism, psychopathy, and Machiavellianism, has become an increasingly popular research focus. Yet questions remain over whether the DT components are sufficiently distinct from another. We examined the nomological networks of each DT component through a meta-analysis of the available literature on the DT.

Quality of Life and Functioning in Comorbid Posttraumatic Stress Disorder and Major Depressive Disorder After Treatment With Citalopram Monotherapy.

Objectives: Posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) often have high comorbidity, consequently influencing patient-reported outcomes of depressive symptom severity, quality of life (QOL), and functioning. We hypothesized that the combined effects of concurrent PTSD and MDD would result in worse treatment outcomes, whereas individuals who achieved MDD remission would have better treatment outcomes.

Methods: We analyzed 2280 adult participants who received level 1 treatment (citalopram monotherapy) in the Sequenced Treatment Alternatives to Relieve Depression study, including 2158 participants with MDD without comorbid PTSD and 122 participants with MDD with comorbid PTSD (MDD + PTSD).

Patient-reported functioning in major depressive disorder.

Objectives: Compared with the general population, patients with major depressive disorder (MDD) report substantial deficits in their functioning that often go beyond the clinical resolution of depressive symptoms. This study examines the impact of MDD and its treatment on functioning.

Methods: From the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial, we analyzed complete data of 2280 adult outpatients with MDD at entry and exit points of each level of antidepressant treatment and again 12 months post treatment.

Parent, peer, and executive function relationships to early adolescent e-cigarette use: a substance use pathway?

Introduction: Little is known about influences on e-cigarette use among early adolescents. This study examined influences that have been previously found to be associated with gateway drug use in adolescents: demographic (age, gender, ethnicity, free lunch), social contextual influences of parents and peers, and executive function deficits (EF).

Methods: A cross-sectional survey was administered to 410 7th grade students from two diverse school districts in Southern California (M age;=12.
