The reliability of individual trial event-related potential (ERP) components extracted from electroencephalogram has been consistently questioned since ERP research began. This ambivalence is based on misunderstood assumptions stemming from Cronbach and Classical Test Theory. Contemporary methods allow for the reliability of individual ERP trials to be estimated and for analyses of these trial-level ERP components to be meaningfully parsed.

Narcissism can be conceived hierarchically at three levels: as a global construct (Level 1), as two dimensions (Level 2; grandiosity and vulnerability), and as a trifurcated model with three underlying dimensions: interpersonal antagonism, narcissistic neuroticism, and agentic extraversion (Level 3). The aim of the study was to examine how narcissism dimensions across the three levels differ in their associations with various forms of interpersonal functioning. The authors assessed multiple domains of interpersonal functioning using data collected from 447 MTurk workers, 606 students, and 365 informants.

Article Synopsis
  • Personality disorders stem from ineffective interpersonal behaviors, and researchers have mostly focused on how individuals view their own and others' behaviors, but not enough on how they perceive others' interpersonal actions.* -
  • A study with 470 undergrads revealed that people prefer interpersonal behaviors that mirror their own, especially regarding warmth, and dislike behaviors that contrast with theirs, regardless of how close the relationship is.* -
  • The research indicates that perceptions of others' behaviors significantly impact personality and psychological well-being, emphasizing the need to consider these perceptions when studying interpersonal dynamics related to personality disorders.*

The Alternative Model of Personality Disorders (AMPD) integrates several theoretical models of personality functioning, including interpersonal theory. The interpersonal circumplex dimensions of warmth and dominance can be conceptualized as traits similar to those in AMPD Criterion B, but interpersonal theory also offers dynamic hypotheses about how these variables that change from moment to moment, which help to operationalize some of the processes alluded to in AMPD Criterion A. In the psychotherapy literature, dynamic interpersonal behaviors are thought to be critical for identifying therapeutic alliance ruptures, yet few studies have examined moment-to-moment interpersonal behaviors that are associated with alliance ruptures at an idiographic level.

The Continuous Assessment of Interpersonal Dynamics (CAID) is an observational coding method that enables continuous tracking of warmth and dominance in both members of a dyad as an interaction unfolds. Research using this tool has revealed dynamic patterns relevant to psychopathology and psychotherapy, suggesting considerable potential for clinical assessment and research. However, CAID data are sensitive to a variety of person and situational factors, and the way that these factors combine to influence CAID data is poorly understood.

Personality disorders are rooted in maladaptive interpersonal behaviors. Previously, researchers have assessed interpersonal behaviors using self-ratings of one's own behaviors and third-person ratings of dyadic interactions. Few studies have examined individuals' perceptions of others' interpersonal behaviors.

The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirically and quantitatively derived dimensional classification system designed to describe the features of psychopathology and, ultimately, to replace categorical nosologies. Among the constructs that HiTOP organizes are "symptom components" and "maladaptive traits," but past HiTOP publications have not fully explicated the distinction between symptoms and traits. We propose working definitions of symptoms and traits and explore challenges, exceptions, and remaining questions.

Article Synopsis
  • The Big Five personality traits (extraversion, agreeableness, openness, conscientiousness, and neuroticism) and the interpersonal circumplex are key frameworks in studying personality and its social impacts.
  • Extraversion and agreeableness are believed to have the strongest connections to interpersonal dynamics, but all five traits influence social interactions in various ways.
  • The study found that each Big Five trait has distinct interpersonal profiles, indicating that even traits not directly associated with social behavior can still significantly impact how individuals relate to others.

We assessed the association of personality pathology with romantic couples' observed interpersonal behaviors. Couples engaged in four discussion tasks, after which observers used the Continuous Assessment of Interpersonal Dynamics method to continuously rate each participant's dominance and warmth over the course of each discussion. Using these ratings, we derived indices of average behaviors and changes in behaviors over the course of discussions.

The Observation of Human-Animal Interaction for Research (OHAIRE) is a coding tool developed to capture the behavior of children when interacting with social partners and animals in naturalistic settings. The OHAIRE behavioral categories of focus are emotional displays, social communication behaviors toward adults and peers, behaviors directed toward animals or experimental control objects, and interfering behaviors. To date, the OHAIRE has been used by 14 coders to code 2,732 min of video across four studies with a total of 201 participants ages 5 to 18 years ( = 10.

The Continuous Assessment of Interpersonal Dynamics (CAID) is a method in which trained observers continuously code the dominance and warmth of individuals who interact with one another in dyads. This method has significant promise for assessing dynamic interpersonal processes. The purpose of this study was to examine the impact of individual sex, dyadic familiarity, and situational conflict on patterns of interpersonal warmth, dominance, and complementarity as assessed via CAID.

The dimensional pathological personality trait model proposed in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition (DSM-5), Section III Criterion B, has shown promising results for its validity and utility in conceptualizing personality pathology. However, as its structural equivalence across sex is yet to be tested, the validity for the model across males and females remains uncertain. In the present article, we examined sex measurement invariance of the DSM-5 trait model in a large undergraduate sample using the Personality Inventory for DSM-5.

The categorical model of personality disorder classification in the American Psychiatric Association's (5th ed. []; American Psychiatric Association, 2013 ) is highly and fundamentally problematic. Proposed for 5 and provided within Section III (for Emerging Measures and Models) was the Alternative Model of Personality Disorder (AMPD) classification, consisting of Criterion A (self-interpersonal deficits) and Criterion B (maladaptive personality traits).

In this article, we organize multimethod, multitimescale data around the interpersonal situation, a conceptual framework that can be used to integrate personality, psychopathology, and psychotherapy constructs in order to guide the assessment of clinical dynamics. We first describe the key variables of the interpersonal situation model and articulate methods for assessing those variables as they manifest (a) across different levels of personality, (b) across situations, and (c) within situations. We next use a case to demonstrate how to assess aspects of the interpersonal situation in a manner that enhances case conceptualization and facilitates the evaluation of clinical hypotheses.

There is a long history of using personality to subtype patients in treatment for substance use disorders (SUD). However, no one has validated a typology of SUD patients using a structural model of normal-range personality, particularly indicating whether subtypes differ on treatment processes and outcomes. We developed a personality-based typology among 196 military veterans enrolled in residential SUD treatment at a Veterans Affairs medical center.

In our article "Evidence for the Criterion Validity and Clinical Utility of the Pathological Narcissism Inventory" (2012), we provided incorrect values for the r(contrast-cv) coefficients we presented in Table 1. In the current report, we provide correct r(contrast-cv) values in Table 1 and discuss the implications of our updated results, particularly with respect to how these results differ from our initial report.

Impulsivity, a multi-faceted construct characterized by rash, unplanned actions and a disregard for long-term consequences, is associated with poor substance use disorder (SUD) treatment outcomes. Little is known though about the influence of impulsivity on treatment process variables critical for initiating and maintaining behavioral change. This knowledge gap is important as different aspects of impulsivity may be susceptible to diverse cognitive, behavioral and pharmacological influences.

Although several studies suggest that negative affect and interpersonal problems serve as important contributors for eating-related problems, much of this research has been conducted among women and less is known about their roles in precipitating and maintaining eating problems among men. Previous studies with undergraduate men suggest that difficulties in emotion regulation are associated with disordered eating even after controlling for differences in body mass index (BMI) and negative affect. The present study sought to replicate these findings and extend them to assess any unique variance explained by problems in interpersonal functioning among both men and women.
