Preliminary Support

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.

AbstractPersonality disorders (PDs) have been thought historically to be enduring, inflexible, and set in psychological stone relatively firmly; however, empirical findings from recent prospective multiwave longitudinal studies establish otherwise. Nearly all modern longitudinal studies of personality disorder have documented considerable change in PDs over time, suggesting considerable flexibility and plasticity in this realm of psychopathology. The factors and mechanisms of change in the PDs remain essentially opaque, and this area of PD research is just beginning to be probed using candidate predictors of change, such as personality systems. In this report, we investigate whether change in temperament dimensions (emotionality, activity, and sociability) predicts change in schizoid personality disorder. We present a latent growth framework for addressing this question and provide an illustration of the approach using data from the Longitudinal Study of Personality Disorders. Schizoid personality disorder was assessed using two different methodologies (structured psychiatric interview and self-report) and temperament was assessed using a well-known psychometric measure of temperament. All constructs were measured at three time points over a 4-year time period. To analyze these panel data, we fitted a covariance structure model that hypothesized simultaneous relationships between initial levels and rates of change in temperament and initial levels and rates of change in schizoid personality disorder. We found that rates of change in the core temperament dimensions studied do not predict rates of change in schizoid personality over time. We discuss the methodological advantages of the latent growth approach and the substantive meaning of the findings for change in schizoid personality disorder.

AbstractIt is argued that personality pathology represents the final emergent product of a complex interaction of underlying neurobehavioral systems as well as environment inputs. A number of factors may be involved in the developmental pathway and a cascading of effects is plausible, although a unifying cascade for all personality disorders is not likely. The present study suggests a possible cascade relevant to one personality disorder: schizoid personality disorder in emerging adulthood. In brief, it is hypothesized that the absence of a relationship characterized by a rich degree of psychological proximal process in early childhood, which is associated with nurturance and the facilitation of more complex development, predicts impairment in the actualization of the affiliation system (i.e., that system that facilitates interpersonal connectedness and social bonds in human beings and is under substantial genetic influence), and this impairment in the affiliation system predicts the appearance of schizoid personality disorder symptoms in emerging adulthood (late teens/early 20s), which persists over time into emerging adulthood. The impairment in the affiliation system is argued to proceed through childhood sociality as reflected in temperament on through adult personality as reflected in communal positive emotion. Furthermore, it is also hypothesized that the relationship between proximal processes and the affiliation system maintains irrespective of other childhood temperament factors that might adversely impact early parent/caregiver and child relations. The data for a preliminary illustration of this possible cascade are drawn from The Longitudinal Study of Personality Disorders, which is a prospective, multiwave study of personality disorders, personality, and temperament in a large sample of adults drawn from a nonclinical population.

Abstract Personality disorders are enduring patterns of inner experience and behavior that deviate markedly from those expected by the individual's culture; these inflexible and pervasive patterns reflect issues with cognition, affectivity, interpersonal functioning and impulse control, and lead to clinically significant distress or impairment in social, occupational, or other important areas of functioning. The AMA Guides to the Evaluation of Permanent Impairment, Fourth Edition, defines two specific personality disorders, in addition to an eleventh condition, Personality Disorder Not Otherwise Specified. Cluster A personality disorders include paranoid, schizoid, and schizotypal personalities; of these, Paranoid Personality Disorder probably is most common in the legal arena. Cluster B personality disorders include antisocial, borderline, histrionic, and narcissistic personality. Such people may suffer from frantic efforts to avoid perceived abandonment, patterns of unstable and intense interpersonal relationships, an identity disturbance, and impulsivity. Legal issues that involve individuals with cluster B personality disorders often involve determination of causation of the person's problems, assessment of claims of harassment, and assessment of the person's fitness for employment. Cluster C personality disorders include avoidant, dependent, and obsessive-compulsive personality. Two case histories illustrate some of the complexities of assessing impairment in workers with personality disorders, including drug abuse, hospitalizations, and inpatient and outpatient psychotherapy.

Test Retest Reliability

Summary: Short-term stability or test-retest reliability of self-reported personality traits is likely to be biased if the respondent is affected by a depressive or anxiety state. However, in some studies, DSM-oriented self-reported instruments have proved to be reasonably stable in the short term, regardless of co-occurring depressive or anxiety disorders. In the present study, we examined the short-term test-retest reliability of a new self-report questionnaire for personality disorder diagnosis (DIP-Q) on a clinical sample of 30 individuals, having either a depressive, an anxiety, or no axis-I disorder. Test-retest scorings from subjects with depressive disorders were mostly unstable, with a significant change in fulfilled criteria between entry and retest for three out of ten personality disorders: borderline, avoidant and obsessive-compulsive personality disorder. Scorings from subjects with anxiety disorders were unstable only for cluster C and dependent personality disorder items. In the absence of co-morbid depressive or anxiety disorders, mean dimensional scores of DIP-Q showed no significant differences between entry and retest. Overall, the effect from state on trait scorings was moderate, and it is concluded that test-retest reliability for DIP-Q is acceptable.

Abstract. The goal of the present investigation was to expand the literature on impulsivity and Cluster B personality disorders (PDs) by conceptualizing impulsivity in a multidimensional manner. Two separate undergraduate samples (n = 223; n = 204) completed measures of impulsivity and Cluster B dimensions. Impulsivity was indeed predictive of Cluster B dimensions and, importantly, each PD scale exhibited a unique impulsivity profile. Findings for borderline PD scores were highly consistent across samples and strongly and positively associated with urgency and lack of perseverance, as expected. Findings for the other PD dimensions also exhibited a fair amount of consistency. Implications of these findings for diagnostic classification and treatment are discussed.

Introduction: Social and personality psychologists have described Machiavellianism as a pragmatic, callous-unemotional, exploitative and manipulative attitude towards others. Several former studies linked Machiavellian personality traits and interpersonal problems or personality dysfunction. Aim: The aim of this study was to reveal the connection between Machiavellianism and interpersonal problems that are characteristic of personality disorders. Method: 252 participants (146 females and 106 males, aged 32.46±5.39 years, mean±SD) filled out self-report measures of Machiavellianism and personality disorder related interpersonal problems. Results: There was a medium strength relationships between Machiavellianism and several interpersonal problems. Aggression and ambivalence proved to be significant predictors of Machiavellian personality traits. Conclusions: Results are discussed in relation to the patient–therapist bond. Orv.
