Rapid Effects of MDMA Administration on Self-Reported Personality Traits and Affect State: A Randomized, Placebo-Controlled Trial in Healthy Adults.

3,4-methylenedioxymethamphetamine (MDMA) assisted therapy has been shown to be a safe and effective treatment for PTSD and emerging research suggests a change in personality traits may be a factor in treatment response. Most prior research on MDMA and personality has focused on cross-sectional comparisons of MDMA users and non-users; as such, well-controlled research assessing personality and affective states following MDMA vs placebo administration is needed. In the current pre-registered study, we investigated the impact of MDMA administration on five-factor model (FFM) traits and affective states before and 48 h after drug administration in a randomized, placebo-controlled study of healthy adults ( = 34).

Is Personality Pathology Ego-Syntonic? Self- and Meta-Perception of Maladaptive Personality Traits.

Research has challenged the assumption that personality pathology is "ego-syntonic" or perceived favorably and consistent with one's self-image. The present study employed a community sample ( = 401) to examine relations between self-rated maladaptive personality and liking of maladaptive traits in self and others as well as meta-perception of personality pathology (i.e.

Psychometric evaluation of a Visual Interpersonal Analog Scale.

Interpersonal theory organizes social behavior along dominant (vs. submissive) and warm (vs. cold) dimensions.

Factor Structure of the FFM ATM: Antagonism, Emotional Stability, Impulsivity, and Agency.

The Dark Triad (DT) refers to three socially aversive personality constructs: psychopathy, narcissism, and Machiavellianism. In response to concerns with existing self-report questionnaires measuring these constructs, we created the Five Factor Model Antagonistic Triad Measure (FFM ATM), which uses 46 items to assess multidimensional, faceted versions of the three DT constructs. The current pre-registered study used two large samples (s = 600 and 1,247) to explore the structure of the FFM ATM using bass-ackward factor analyses.

Check and report: The state of data validity detection in personality disorder science.

The backbone of any field of science is quality data. In personality disorder (PD) science and the broader field of clinical psychology, researchers must consider whether participants were attentive to, understood, and responded honestly and with sufficient effort to self-report questionnaires. We review literature regarding the prevalence of invalid (i.

Continuous-Time Modeling of the Bidirectional Relationship Between Incidental Affect and Physical Activity.

Background: Previous research suggests that there is a bidirectional relationship between incidental affect (i.e., how people feel in day-to-day life) and physical activity behavior.

Narcissism and the DSM-5 alternative model of personality disorder.

In the Section III alternative model of personality disorder, narcissistic personality disorder (NPD) is assessed via required elevations on 2 of 4 Criterion A domains of personality dysfunction (i.e., self-direction, identity, empathy, intimacy) and 2 personality traits (Criterion B: attention seeking and grandiosity).

Incremental and interactive relations of triarchic psychopathy measure scales with antisocial and prosocial correlates: A preregistered replication of Gatner et al. (2016).

Meanness (i.e., callousness/unemotionality, antagonism) and disinhibition (e.

Momentary dynamics of emotion-based impulsivity: Exploring associations with dispositional measures of externalizing and internalizing psychopathology.

Emotion-based impulsivity has emerged as an important transdiagnostic risk factor for both internalizing and externalizing psychopathology. However, it is unclear how this dynamic process unfolds within individuals. We measured urgency within-persons as the momentary association between impulsivity and contemporaneous negative and positive affect in 4 ecological momentary assessment samples (N = 233[16,202 observations]; N = 302[11,360]; N = 311[17,517]; N = 291[20,297]) that span clinical, community, and student populations.

Searching high and low for meaningful and replicable morphometric correlates of personality.

Recent personality neuroscience research in large samples suggests that personality traits tend to bear null-to-small relations to morphometric (i.e., brain structure) regions of interest (ROIs).

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.

Impulsivity, Affect, and Stress in Daily Life: Examining a Cascade Model of Urgency.

Using multilevel structural equation modeling, the authors examined within- and between-person predictors of daily impulsivity, with a particular focus on testing a cascade model of affect and daily stress in a 100-day daily diary study of 101 psychiatric patients with personality disorder diagnoses. On average (i.e.

A day in the life of Narcissus: Measuring narcissistic grandiosity and vulnerability in daily life.

There is growing interest in understanding the fluctuations in grandiose and vulnerable narcissistic states over time. Momentary data collection is vital in facilitating this new area of inquiry. Two narcissism adjective scales, the Narcissistic Grandiosity Scale and the Narcissistic Vulnerability Scale, have recently been developed for this purpose.
