Identifying Psychopathy Subtypes on the Basis of Personality Structure.

The authors used model-based cluster analysis to identify subtypes of criminal psychopaths on the basis of differences in personality structure. Participants included 96 male prisoners diagnosed as psychopathic, using the Psychopathy Checklist Revised (PCL-R; R. D. Hare, 1991). Personality was assessed using the brief form of the Multidimensional Personality Questionnaire (MPQ-BF; C. J. Patrick, J. J. Curtin, & A. Tellegen, 2002). The best-fitting model yielded two clusters. Emotionally stable psychopaths were characterized by low Stress Reaction and high Agency. Aggressive psychopaths were characterized by high Negative Emotionality, low Constraint, and low Communion. These results suggest that psychopaths as defined by the PCL-R includes distinct subtypes, distinguishable in terms of personality structure, that may reflect different etiologies.

The Validity of the Five-Factor Model Prototypes for Personality Disorders in Two Clinical Samples.

The authors examined the validity of D. R. Lynam and T. A. Widiger's (2001) prototypes for personality disorders (PDs) derived from the facets of the 5-factor model (FFM) of personality in 2 clinical samples. In the 1st sample (N = 94), there was good agreement between the prototypes generated by experts and the profiles reported by patients. These FFM PD similarity scores also demonstrated good convergent and discriminant validity with results from a semistructured interview and a self-report measure of Axis II pathology. In the 2nd sample (N = 132), the FFM PD similarity scores demonstrated excellent longitudinal stability and good predictive validity with regard to consensus ratings of PD features. The implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Alcohol, Tobacco, and Drug Use Disorders and Personality Disorder Symptoms.

In a nonclinical sample of 395 young adults, the authors evaluated the relations between major personality traits, Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) personality disorder symptoms, and DSM-IV alcohol use disorders (AUDs). Consistent with previous findings, traits related to disinhibition and negative affectivity were consistently associated with AUDs, as were Cluster B personality disorder symptoms (especially antisocial and borderline disorder symptoms). Multivariate analyses revealed that Cluster B symptoms were significantly associated with AUDs above and beyond what was accounted for by personality traits. Further, the authors found differential patterns of relations between other substance use disorders (SUDs; i.e., tobacco dependence and drug use diagnoses) and personality disorder symptoms. Overall, these results suggest that personality disorder symptoms predict unique variance in SUDs that reflect maladaptive aspects of personality traits.

Differing Conceptions of Moral Exemplarity: Just, Brave, and Caring.

People's conceptions of different types of moral exemplarity were examined in an attempt to augment the current emphasis on moral rationality with a fuller understanding of moral personality. In Study 1 (with 805 adults), a free-listing procedure was used to generate the attributes of 3 types of moral exemplars (just, brave, and caring). In Study 2 (with 401 undergraduates), prototypicality- and personality-rating procedures were used to generate a personality profile for each type of moral exemplar and to examine the relations among them. In Study 3 (with 240 undergraduates), a similarity-sorting procedure was used to identify the typologies implicit in people's understanding of these different types of moral exemplarity. The findings indicate that moral excellence can be exemplified in rather divergent ways and that understanding of moral functioning would be enhanced by attention to this wider range of moral virtues.

Parents' Personality and Infants' Temperament as Contributors to Their Emerging Relationship.

The authors examined the contributions of infant's temperament and parent's personality to their relationship. In Study 1, 102 infants, mothers, and fathers were studied when infants were 7 months; in Study 2, 112 infants and mothers were followed from 9 to 45 months. Infants' temperament (joy, fear, anger, and attention) was observed in standard temperament paradigms. Parents' personality measures encompassed the Big Five traits and Empathy in Study 1 and Mistrust, Manipulativeness, Aggression, Dependency, Entitlement, and Workaholism in Study 2. Parent-child relationship (shared positive affect and parental responsiveness in Studies 1 and 2 and parental tracking of the infant in Study 1) was observed in naturalistic contexts. In Study 1, mothers' Neuroticism, Empathy, and Conscientiousness and fathers' Agreeableness, Openness, and Extraversion related to the relationship with the infants. All measures of infant temperament also related to the emerging relationship. In Study 2, maternal Mistrust, Manipulativeness, Dependency, and Workaholism predicted the relationship with the child.

Flux, Pulse, and Spin: Dynamic Additions to the Personality Lexicon.

Personality constructs were proposed to describe intraindividual variability in interpersonal behavior. Flux refers to variability about an individual's mean score on an interpersonal dimension and was examined for the 4 poles of the interpersonal circumplex. Pulse and spin refer to variability about an individual's mean extremity and mean angular coordinate on the interpersonal circumplex. These constructs were measured using event-contingent recording. Latent state-trait analyses indicated high stability of flux in submissive, agreeable, and quarrelsome behaviors and some stability in the flux of dominance. Further analyses indicated moderate to high stability in pulse and spin. Neuroticism predicted greater pulse, spin, and submissive behavior flux. Extraversion predicted greater flux in agreeable behavior. In contrast, Agreeableness predicted reduced spin and quarrelsome behavior flux. Social environmental variables predicted greater flux in dominant behavior. Flux, pulse, and spin provide reliable and distinctive additions to the vocabulary for describing individual differences.

Escapable Conclusions: Toomela (2003) and the Universality of Trait Structure.

A. Toomela (2003) concluded that personality structure may be shaped by a cultural mechanism, word meaning structure, and that the apparent universality of the Five-Factor Model (FFM) was the result of inadequate sampling of concrete thinkers. A reanalysis using targeted rotation showed that the intended structure was generally replicated; small deviations in the most concrete thinkers were probably due to measurement error. The reanalysis authors found no evidence of structural differences in a second sample of adults classified as concrete or abstract thinkers. The FFM structure has been replicated in many samples containing individuals with cognitive or educational limitations; observer ratings may be preferred if these limitations are severe. To date, there is no compelling evidence that culture affects personality structure. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Goal and Personality Trait Development in Emerging Adulthood.

The present research examined continuity and change in the importance of major life goals and the relation between change in goals and change in personality traits over the course of college (N = 298). Participants rated the importance of their life goals 6 times over a 4-year period and completed a measure of the Big Five personality traits at the beginning and end of college. Like personality traits, life goals demonstrated high levels of rank-order stability. Unlike personality traits assessed during the same period and in the same sample, the mean importance of most life goals decreased over time. Moreover, each goal domain was marked by significant individual differences in change, and these individual differences were related to changes in personality traits. These findings provide insights into the relatively unstudied question of how life goals change during emerging adulthood. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Dark Side of Relational Pursuit: From Attraction to Obsession and Stalking,.

Review declaring pleasant surprise with this relatively short book on stalking. It contains 164 pages of text, and provides a thorough context for understanding and treating stalking behavior, including a focus on both victim and perpetrator. The book is divided into five chapters. The first of these defines the nature of stalking behavior. Stalking is defined as harmful conduct, which involves unwanted communication and repeated unwanted intrusion by one individual upon another. The review notes that stalking behavior has three defining characteristics--(a) relentless and persistent contact, which is (b) unwanted and (c) adverse to the recipient. It is further observed that there is no single motive for stalking, nor any specific psychological profile for the personality of stalkers.

Does who you marry matter for your health? Influence of patients' and spouses' personality on their partners' psychological well-being following coronary artery bypass surgery.

Research suggests that presurgical personality attributes influence postsurgical well-being in both patients and their spouses in the context of coronary artery bypass grafting (CABG) surgery. The authors hypothesized that a spouse's characteristics would influence a partner's psychological well-being, regardless of whether he or she was the patient or the caregiver. In this study, 111 male patients and their caregiver spouses completed measures of neuroticism, optimism, perceived marital satisfaction, and depression prior to elective CABG. Follow-up was conducted at 18 months. As expected, higher caregiver presurgical neuroticism predicted higher patient depressive symptoms at follow-up, with caregiver's concurrent 18-month affect controlled for. Likewise, higher patient presurgical neuroticism predicted higher caregiver depressive symptoms at follow-up. Additionally, higher patient presurgical depressive symptoms and lower presurgical optimism contributed to greater caregiving burden. Relationship satisfaction moderated these effects. These results suggest that partners' personality traits are important determinants of both patients' and their caregiving spouses' well-being.
