Detecting the Presence of a Personality Disorder Using Interpersonal and Self-Dysfunction

Narcissistic and dependent traits and behavior in four archetypal 2-person, 2-choice games

Introduction

The characteristic behaviors we use to define personality pathology arise from specific interpersonal interactions. In an effort to create a laboratory-based context in which behavior might be expected to be influenced by particular personality traits, we used four 2-person, 2-choice games (the Prisoner's Dilemma, Chicken, Leader, and Hero games) to create a simulated interaction and focused specifically on narcissism and dependency.

Method

An online sample of 1137 (35% male, M age = 38.46 years, SD age = 13.20) participants completed brief, self-reported measures of trait narcissism and dependency and played one of the four games. Before deciding how to act or react, participants received either no message, a promise to cooperate, or a threat to defect from a (confederate) partner.

Results

When receiving no message, those who cooperated in the Prisoner's Dilemma had lower trait narcissism, while those who defected in the Chicken and Leader games had higher trait narcissism. Also with no message, participants who cooperated in the Hero game had higher trait dependency. Promises only affected the relationship between trait narcissism in the Leader game while threats only affected the relationship between trait dependency in the Chicken game.

Discussion

These findings add to the limited behavioral research on personality pathology and largely support established interpersonal conceptualizations and models. Future work might extend these findings using even more ecologically valid approaches to explore the behavioral correlates of personality traits that have important implications for interpersonal interactions.

The Development of Criterion A Personality Pathology: The Relevance of Childhood Social Functioning for Young Adult Daily Self-Functioning

The DSM-5 alternative model for the diagnosis of personality disorders (AMPD) states that self- and interpersonal (Criterion A) dysfunction is necessary to diagnose a personality disorder, qualified by maladaptive personality trait profiles (Criterion B). This study tested whether childhood maladaptive personality traits predict interpersonal dysfunction during adolescence, which further predicts lower self-functioning in young adulthood. A mixed clinical-community sample of 157 10-year-olds participated for ten years. Social problems and personality traits were rated by parents at age 10 and 12. At age 20, young adults completed 14 daily ratings of self-functioning. Traits of emotional instability and disagreeableness predicted social problems and self-problems. Social problems predicted worse self-functioning in adulthood. An indirect effect of childhood narcissistic traits on higher levels of self-functioning via lower levels of social problems was found. Results are discussed in terms of their contribution to our understanding of the AMPD from a developmental perspective.

Identity and Personality Pathology: A Convergence Across the DSM-5 Personality Disorder Model and the Alternative Model for Personality Disorders

Long-standing theory regarding personality pathology as well as the recently proposed DSM-5 Alternative Model for Personality Disorders (AMPD) posit that self/identity problems are a hallmark feature cutting across forms of personality pathology. With emergence of the AMPD, researchers have started to focus empirical investigations on identity pathology as a transdiagnostic factor across personality pathology. The current study investigated identity pathology across indicators of personality pathology from both the current categorical perspective (DSM-5 PD) and the dimensional perspective in the AMPD. Identity diffusion and low self-concept clarity were correlated with all PD feature scales and all maladaptive personality dimension scales. Regression analyses revealed most indicators of personality pathology were significant correlates of identity diffusion and low self-concept clarity. Borderline and Avoidant PD feature scales and Negative Affectivity and Detachment maladaptive personality dimension scales emerged as the strongest correlates of identity pathology. The role that identity pathology plays in personality pathology is highlighted.

What are we missing in dimensional models that might explain core dynamic processes in borderline personality disorder? Commentary on Miskewicz et al. (2022)

Comments on the original article by Miskewicz et al. (see record 2021-98114-001) regarding dimensional models that might explain core dynamic processes in borderline personality disorder. Miskewicz et al.'s findings provide strong evidence that although dynamic processes in borderline personality disorderare important, a trait-only model cannot fully explain core dynamic processes underlying symptom fluctuations as a function of context in borderline personality disorder (BPD). In fact, any single model is likely insufficient to explain BPD functioning in all its complexity. An important next step is to examine how traits and other theoretically and empirically informed constructs might synergistically (rather than merely independently) explain the dynamic expression of BPD symptoms in real-world contexts.

Impulsivity and Emotional Dysregulation Predict Choice Behavior During a Mixed-Strategy Game in Adolescents With Borderline Personality Disorder

Impulsivity and emotional dysregulation are two core features of borderline personality disorder (BPD), and the neural mechanisms recruited during mixed-strategy interactions overlap with frontolimbic networks that have been implicated in BPD. We investigated strategic choice patterns during the classic two-player game, Matching Pennies, where the most efficient strategy is to choose each option randomly from trial-to-trial to avoid exploitation by one’s opponent. Twenty-seven female adolescents with BPD (mean age: 16 years) and twenty-seven age-matched female controls (mean age: 16 years) participated in an experiment that explored the relationship between strategic choice behavior and impulsivity in both groups and emotional dysregulation in BPD. Relative to controls, BPD participants showed marginally fewer reinforcement learning biases, particularly decreased lose-shift biases, increased variability in reaction times (coefficient of variation; CV), and a greater percentage of anticipatory decisions. A subset of BPD participants with high levels of impulsivity showed higher overall reward rates, and greater modulation of reaction times by outcome, particularly following loss trials, relative to control and BPD participants with lower levels of impulsivity. Additionally, BPD participants with higher levels of emotional dysregulation showed marginally increased reward rate and increased entropy in choice patterns. Together, our preliminary results suggest that impulsivity and emotional dysregulation may contribute to variability in mixed-strategy decision-making in female adolescents with BPD.

Contemporary psychological perspectives of personality disorders

PURPOSE OF REVIEW

The aim of this study was to review the recent literature on contemporary psychological perspectives of personality disorders, including novel psychotherapeutic interventions aimed at these vulnerable individuals.

RECENT FINDINGS

Among the various psychological theories and models of personality disorders, still the most popular and researched are psychodynamic, cognitive and interpersonal perspectives. More specifically, object relations theory, cognitive schema conceptualization and interpersonal circumplex model have produced the most empirical investigations of personality disorders in recent years. Latest work has suggested that all three perspectives have contributed to and are compatible with the dimensional personality disorders framework in DSM-5-AMPD and ICD-11 (including level of personality functioning and personality traits). These models have yielded specific psychological treatments of personality disorders; although most psychotherapies have been constructed for patients with borderline personality disorder (BPD), there is an increasing number of treatment modalities aimed at individuals with other forms of personality disorder, such as those with narcissistic or antisocial traits/disorders. More research into their effectiveness and long-term benefits is necessary.

SUMMARY

Novel research keeps updating our knowledge on the cause, manifestations and psychological treatments of personality disorders, particularly from psychodynamic, cognitive and interpersonal perspectives.

Opioids and social bonding: Effect of naltrexone on feelings of social connection and ventral striatum activity to close others

Close social bonds are critical to immediate and long-term well-being. However, the neurochemical mechanisms by which we remain connected to our closest loved ones are not well understood. Opioids have long been theorized to contribute to social bonding via their actions on the brain. But feelings of social connection toward one's own close others and direct comparisons of ventral striatum (VS) activity in response to close others and strangers, a neural correlate of social bonding, have not been explored. Therefore, the current clinical trial examined whether opioids causally affect neural and experiential signatures of social bonding. Eighty participants were administered naltrexone (n = 40), an opioid antagonist that blocks natural opioid processing, or placebo (n = 40) before completing a functional MRI scan where they viewed images of their close others and individuals they had not seen before (i.e., strangers). Feelings of social connection to the close others and physical symptoms commonly experienced when taking naltrexone were also collected. In support of hypotheses, naltrexone (vs. placebo) reduced feelings of social connection toward the close others (e.g., family, friends, romantic partners). Furthermore, naltrexone (vs. placebo) reduced left VS activity in response to images of the same close others, but did not alter left VS activity to strangers. Finally, the positive correlation between feelings of connection and VS activity to close others present in the placebo condition was erased by naltrexone. Effects remained after adjusting for physical symptoms. Together, results lend support to theories suggesting that opioids contribute to social bonding, especially with our closest loved ones.

Importance of Self and Other in Defining Personality Pathology

Criteria A of the DSM-5 Alternative Model for Personality Disorders (AMPD) defines personality pathology in terms of impairments in "self" (identity, self-direction) and "interpersonal" (empathy, intimacy) functioning. Articulated as a set of dynamic regulatory and relational processes that are stratified in the Level of Personality Functioning Scale, these impairments involve how individuals think and feel about themselves and others and how they relate to others. Defining personality pathology in terms of regulatory and relational processes involving self and other, and distinguishing severity of personality pathology from individual differences in its expression (Criteria B), offers the AMPD several advantages. First, it distinguishes the nature and severity of personality pathology from other forms of psychopathology. Second, it allows the AMPD to integrate personality structure and personality processes. Third, it is highly suitable for synthesis with the Contemporary Integrative Interpersonal Theory of personality. Finally, beyond the interpersonal perspective, it facilitates even broader theoretical and treatment integration.

Personality Disorders as Emergent Interpersonal Syndromes: Psychopathic Personality as a Case Example

Personality disorders have long been bedeviled by a host of conceptual and methodological quandaries. Starting from the assumption that personality disorders are inherently interpersonal conditions that reflect folk concepts of social impairment, the authors contend that a subset of personality disorders, rather than traditional syndromes, are emergent interpersonal syndromes (EISs): interpersonally malignant configurations (statistical interactions) of distinct personality dimensions that may be only modestly, weakly, or even negatively correlated. Preliminary support for this perspective derives from a surprising source, namely, largely forgotten research on the intercorrelations among the subscales of select MMPI/MMPI-2 clinical scales. Using psychopathic personality as a case example, the authors offer provisional evidence for the EIS hypothesis from four lines of research and delineate its implications for personality disorder theory, research, and classification. Conceptualizing some personality disorders as EISs elucidates long-standing quandaries and controversies in the psychopathology literature and affords fruitful avenues for future investigation.
