Background: There is growing interest in research understanding the individual-specific predictors of child callous-unemotional (CU) traits, particularly in early childhood. Objective: This study reviewed evidence from studies that investigated the relationship between early child temperament factors (between 0 and 3 years) and CU traits in…

This study examined the link between academic majors and Dark Triad personality traits in 2,387 Greek university students. Utilizing Bifactor Exploratory Structural Equation Modeling, we identified a general dark factor (D-factor) and three specific traits. Latent Profile Analysis revealed four personality clusters: self-centric personalities,…

The current study uniquely examines mattering and narcissism and reflects our contention that pathological narcissism involves an excessive need to matter and a hypersensitivity to being devalued and not mattering to other people. Specifically, we evaluated the proposed association between pathological narcissism and deficits in mattering by…

We developed and validated a self-report scale for screening pathological traits of dependent personality disorder (DPD) from the Hierarchical Taxonomy of psychopathology (HiTOP) perspective. The sample was 693 adults who answered the new scale, the Dimensional Clinical Personality Inventory DPD (IDCP-DPD), the PID-5, the FFDI, and the FFBI. The…

The current study aimed to develop, and examine the psychometric properties of, an Arabized Jordanian version of the Big Three Perfectionism Scale (BTPS) which consists of 45 items distributed on 10 first-order factors ("facets") and three higher-order factors (i.e., rigid perfectionism, self-critical perfectionism, and narcissistic…

Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

The present study aimed to explore the mediating pathway on internet addiction through vengeance. The sample was consisted of 392 university students (N female = 242, 61.7% and N male = 150, 38.3%). The ages ranged between 18 and 35, with a mean age of 21.6 (SD = 1.95). The sample completed Young's Internet Addiction Test-Short Form, The Vengeance…

Previous studies suggested that perceived social support (PSS) significantly contributes to psychological wellbeing (PWB), partially explained by the sense of mattering. Nevertheless, individuals with different personality might perceive social support in different ways from the other. The interaction of PSS with trait narcissism, one of the dark…

Female Phenotype Theory (FPT) suggests that autistic women often present with less obvious social impairments than autistic men. We examined the possibility of an exaggerated female phenotype among undiagnosed but probably autistic women. In two nationwide online surveys, we compared self-reported social functioning and mental health between…

Ostracism and dark triad personality traits have been found to be linked with social media addiction. Despite the well-established relationship between the dark triad (i.e., narcissism, machiavellianism, and psychopathy) and social media addiction, there is limited research on their mediating effect. In the present study, we tested a hypothetical…

Studies have shown that socially prescribed perfectionism (SPP) is a critical predictor of depression. However, few studies have explored the mechanisms underlying the effects of SPP on depression in Chinese adolescents. Accordingly, the current study aims to explore the relationship between SPP and depression among Chinese adolescents, including…

The dark core of personality is a recent construct that encompasses the malevolent, antagonistic, and aversive side of human nature that represents the common inner core of dark personality traits. The aim of the present study is to develop a short, multidimensional, and invariant version of the dark core of personality D70 measure. Two samples of…

Objective: The current study evaluated frequency of nonsuicidal self-injury (NSSI) and associated maladaptive traits between three time periods: pre-pandemic, early pandemic, and later pandemic. Participants: Two college student samples (n = 362; n = 337) were collected via two online studies. Method: Participants completed measures assessing…

For autism spectrum disorder (ASD) in adults there are several diagnostic instruments available with a need for consideration of the psychometric properties. This study aimed to conduct a first psychometric evaluation of a new diagnostic ASD instrument, the NIDA (Dutch Interview for Diagnostic assessment of ASD in adults) in 90 adult males without…

Research on adults indicates other-oriented perfectionism (requiring perfection from others) is associated with various consequential outcomes independent of self-oriented perfectionism (requiring perfection of the self) and socially prescribed perfectionism (believing others require perfection of the self). However, historically, the most widely…
