Mapping Big Five Personality Traits Within and Across Domains of Interpersonal Functioning

The Big Five and the interpersonal circumplex are among the most extensively used structural frameworks in personality research. Of the five factors, extraversion and agreeableness are theorized to carry the most interpersonal context, however, all five factors are likely to have important interpersonal implications. In the present study, we evaluated the associations between domains of interpersonal functioning and the Big Five domains and facets using the bootstrapped structural summary method. Results suggested that all Big Five traits showed prototypical and specific interpersonal profiles, with variability observed across lower order facets and domains of interpersonal functioning. Several Big Five traits and facets not overtly related to interpersonal behavior nonetheless showed specific, prototypical associations to interpersonal profiles. Findings suggest that Big Five traits and facets are saturated with interpersonal content and even personality characteristics that are not explicitly interpersonal may still have specific interpersonal implications.

Construction and Validation of the Interpersonal Influence Tactics Circumplex (IIT-C) Scales

Assessment of interpersonal dispositions (e.g., traits, problems) commonly employs self- and informant-report measures that conform to the two-dimensional interpersonal circumplex (IPC) model. Here, we adopted the IPC and interpersonal theory as a framework for mapping the universe of content of interpersonal influence. Although there are existing measures of influence tactics used in influence research, this literature is divided among disciplines with varying construct definitions and no unifying theory. Here, we define interpersonal influence as the conscious maneuvering of one’s behavior to engender desired responses from others in interpersonal situations. The current article details the construction and validation of the Interpersonal Influence Tactics Circumplex (IIT-C) Scales in two samples ( Ns = 862, 608). The 64-item IIT-C assesses a comprehensive taxonomy of interpersonal influence tactics conforming to the structure of the IPC. Circumplex structure of the IIT-C was confirmed and replicated. Using the structural summary method for circumplex data, associations with other IPC measures, existing measures of influence, normal personality traits, and pathological personality traits supported the validity of IIT-C scores. The IIT-C assesses a theoretically based and empirically derived set of interpersonal influence tactics and provides a common language for integrating distinct streams of influence research by conforming to the IPC.

Seeking a Common Framework for Research on Narcissism: An Attempt to Integrate the Different Faces of Narcissism within the Circumplex of Personality Metatraits

The current paper presents a proposal for integrating different narcissism constructs (grandiose, vulnerable, communal, and collective) within the Circumplex of Personality Metatraits (CPM), an integrative model of personality structure that could also be used to accommodate the narcissism spectrum model. The study was conducted on a community sample ( N = 781 adults). The theoretically predicted locations of the different narcissism constructs within the CPM space were empirically verified using the structural summary method. We found that grandiose, vulnerable, and communal narcissism can be meaningfully located within the CPM, while the status of collective narcissism remains unclear. Thus, the CPM can serve as a personality matrix explaining the differences and similarities between the various faces of narcissism. © 2019 European Association of Personality Psychology

Dark Triad Traits Within the Framework of the Circumplex of Personality Metatraits Model

The present study attempts to locate the Dark Triad traits within the space of the Circumplex of Personality Metatraits Model. The study was conducted on a sample of 339 adolescents (48.2% females) in Poland, which were administered the Circumplex of Personality Metatraits Questionnaire and two measures of the Dark Triad traits, the Short Dark Triad (SD3; Jones & Paulhus, 2014 ), and the Narcissistic Admiration and Rivalry Questionnaire (NARQ; Back et al., 2013 ). We hypothesized that psychopathy and Machiavellianism will be located near Alpha-Minus (Disinhibition), while narcissism will be located near Delta-Minus (Sensation Seeking). Moreover, we expected that the two narcissistic strategies of narcissistic admiration and rivalry will be located near Beta-Plus (Plasticity) and Alpha-Minus, respectively. The hypotheses were tested using the Structural Summary Method, of which the results mostly corroborated our expectations. The overlap of Machiavellianism and psychopathy, as well as narcissism’s place in the Dark Triad, is discussed.

SCZI or PTI – Schizophrenia or Psychosis?

This paper attempts to illustrate the usefulness of therapy follow-up studies with the Rorschach, based on a particularly striking and difficult protocol (including Structural Summary 1 and 2), in which the two indexes pointed to either schizophrenia (Schizophrenia Index, SCZI) or a psychotic episode (Perceptual-Thinking Index, PTI) in an adolescent whose later development was distinctly positive. Implications of the interpretive process are discussed, of the use of both indexes in favor of the PTI, as well as of the danger of depending on single indexes or of using the Rorschach for psychiatric diagnosis.

Interpersonal Problems Across Levels of the Psychopathology Hierarchy

We examined the relationship between psychopathology and interpersonal problems in a sample of 825 clinical and community participants. Sixteen psychiatric diagnoses and five transdiagnostic dimensions were examined in relation to self-reported interpersonal problems. The structural summary method was used with the Inventory of Interpersonal Problems Circumplex Scales to examine interpersonal problem profiles for each diagnosis and dimension. We built a structural model of mental disorders including factors corresponding to detachment (avoidant personality, social phobia, major depression), internalizing (dependent personality, borderline personality, panic disorder, posttraumatic stress, major depression), disinhibition (antisocial personality, drug dependence, alcohol dependence, borderline personality), dominance (histrionic personality, narcissistic personality, paranoid personality), and compulsivity (obsessive-compulsive personality). All dimensions showed good interpersonal prototypicality (e.g., detachment was defined by a socially avoidant/nonassertive interpersonal profile) except for internalizing, which was diffusely associated with elevated interpersonal distress. The findings for individual disorders were largely consistent with the dimension that each disorder loaded on, with the exception of the internalizing and dominance disorders, which were interpersonally heterogeneous. These results replicate previous findings and provide novel insights into social dysfunction in psychopathology by wedding the power of hierarchical (i.e., dimensional) modeling and interpersonal circumplex assessment.

Interpersonal Self-Efficacy, Goals, and Problems of Persistently Depressed Outpatients: Prototypical Circumplex Profiles and Distinctive Subgroups

Severely and persistently depressed outpatients ( n = 138) completed interpersonal circumplex measures of self-efficacy, problems, and values/goals. Compared with normative samples, patients showed deficits in agency: They reported less self-efficacy, especially for being assertive, tough, and influential; stronger goals, especially to avoid conflict or humiliation; and more problems, especially with being too timid, inhibited, and accommodating. Circular and structural summary indices suggested greater variability among patients in goal profiles than in efficacy or problem profiles; nonetheless, latent profile analyses identified coherent subgroups of patients with distinct patterns of efficacy (e.g., lacking confidence for speaking up vs. setting boundaries) and problems (e.g., being overly inhibited vs. self-sacrificing) as well as goals (e.g., to be included vs. unobtrusive). Women and those with more severe symptoms were overrepresented in the least agentic groups. The results show how observing patients through multiple circumplex surfaces simultaneously can help clarify their interpersonal dispositions and inform interventions.

Beyond Description in Interpersonal Construct Validation

The interpersonal circumplex is a well-established structural model that organizes interpersonal functioning within the two-dimensional space marked by dominance and affiliation. The structural summary method (SSM) was developed to evaluate the interpersonal nature of other constructs and measures outside the interpersonal circumplex. To date, this method has been primarily descriptive, providing no way to draw inferences when comparing SSM parameters across constructs or groups. We describe a newly developed resampling-based method for deriving confidence intervals, which allows for SSM parameter comparisons. In a series of five studies, we evaluated the accuracy of the approach across a wide range of possible sample sizes and parameter values, and demonstrated its utility for posing theoretical questions on the interpersonal nature of relevant constructs (e.g., personality disorders) using real-world data. As a result, the SSM is strengthened for its intended purpose of construct evaluation and theory building.
