Personality similarity and friendship: A follow-up study.

This study repeated the procedures of an earlier study (see 35: 2117) that showed similarity of objectively measured (Edwards Personality Preference Schedule) personality characteristics to be a significant correlate of friendship. Experiment I tested the repeatability of this finding with a similar sample (college freshmen) and the results again supported the similarity principle. Experiment II tested the generalizability of the earlier finding. The procedures were applied to a different population (college seniors), and the results failed to confirm the similarity hypothesis. Personality differences between freshmen and seniors can be viewed as a function of increased social and emotional maturity on the part of seniors (Izard, 1962). Perhaps the more "mature" person has less need to see his personality characteristics reflected in his friends. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality profiles of cultures: Aggregate personality traits.

Personality profiles of cultures can be operationalized as the mean trait levels of culture members. College students from 51 cultures rated an individual from their country whom they knew well (N=12,156). Aggregate scores on Revised NEO Personality Inventory (NEO-PI-R) scales generalized across age and sex groups, approximated the individual-level 5-factor model, and correlated with aggregate self-report personality scores and other culture-level variables. Results were not attributable to national differences in economic development or to acquiescence. Geographical differences in scale variances and mean levels were replicated, with Europeans and Americans generally scoring higher in Extraversion than Asians and Africans. Findings support the rough scalar equivalence of NEO-PI-R factors and facets across cultures and suggest that aggregate personality profiles provide insight into cultural differences.

Personality and functional outcome following traumatic brain injury.

Objective: To investigate pre- to postinjury personality change in relation to outcomes following traumatic brain injury (TBI). Design: Prospective analysis of personality ratings, depression, and outcome using multiple regression analyses. Participants: Cohort of 3 clinical trauma groups (mild TBI, moderate-severe TBI, orthopedic injury) and their significant others (SO). Outcome Measures: Independent Living Scale, Vocational Independence Scale, and Mayo-Portland Adaptability Inventory, 1-2 years postinjury. Predictor Variables: Posttraumatic amnesia (PTA); patient and SO NEO Personality Inventory-Revised ratings of preinjury personality taken at 1-2 months postinjury. Results: Personality function was normal for all groups (regardless of rating source) and stable over time. Neuroticism, and specifically depression, accounted for small proportions of variance in functional outcome, beyond PTA. Conclusions: There is little empirical evidence for significant personality disturbance or change up to 2 years post-TBI. Personality and depression contribute modestly to functional outcomes. Results support a distinction between "personality change" and behavior change following TBI. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A Tale of Two Visions: Can a New View of Personality Help Integrate Psychology?

Personality psychology studies how psychological systems work together. Consequently, the field can act as a unifying resource for the broader discipline of psychology. Yet personality's current fieldwide organization promotes a fragmented view of the person, seen through such competing theories as the psychodynamic, trait, and humanistic. There exists an alternative--a systems framework for personality--that focuses on 4 topics: identifying personality, personality's parts, its organization, and its development. This new framework and its view of personality are described. The framework is applied to such issues as personality measurement, psychotherapy outcome research, and education. The new framework may better organize the field of personality and help with its mission of addressing how major psychological systems interrelate.

Personality characteristics and risk-taking tendencies among adolescent gamblers.

Eight hundred and seventeen high school students in the Montreal region completed the DSM-IV-J diagnostic gambling measure, High School Personality Questionnaire (HSPQ), Zuckerman Sensation Seeking Scale (SSS), along with a gambling questionnaire ascertaining gambling participation and gambling-related behaviours. Eight of fourteen personality factors assessed by the HSPQ, as well as three of the four subscales of the SSS differed by gambling severity. A discriminant analysis found that high levels of Disinhibition, Boredom Susceptibility, Cheerfulness and Excitability, as well as low levels of Conformity, and Self-Discipline are strongly associated with the function that best predicts problem gambling severity level. The findings suggest that there exist qualitative differences in personality and risk-taking styles for adolescents based upon the severity of their gambling behaviour, lending support to the premise that certain types of individuals are more susceptible than others to developing a gambling problem.

Exploring the universality of personality judgments: Evidence from the great transformation (1000 BCE–200 BCE).

We examined whether personality judgments were present in texts of the diverse religious and philosophical traditions that emerged during the Great Transformation, an era spanning roughly 1000 BCE to 200 BCE. Some psychologists have suggested that the tendency of humans to judge personality has evolved; if some ancient societies failed to record personality judgments, it would be evidence against such an evolutionary position. In addition, learning about the prevalence and specifics of ancient personality judgments can help psychologists better understand the prehistory of personality psychology. Eight cultural traditions were studied: two each from China (Confucianism, Taoism), Greece (Classical and Hellenistic philosophy), India (Buddhism, Hinduism), and the Middle East (Judaism, Zoroastrianism). We found evidence that personality judgments were an important aspect of all of these traditions. Not only did people judge one another, but they also offered instructions on how to judge others.

Personality types in adolescence: Change and stability and links with adjustment and relationships: A five-wave longitudinal study.

We examined change and stability of the 3 personality types identified by Block and Block (1980) and studied their links with adjustment and relationships. We used data from a 5-wave study of 923 early-to-middle and 390 middle-to-late adolescents, thereby covering the ages of 12–20 years. In Study 1, systematic evidence for personality change was found, in that the number of overcontrollers and undercontrollers decreased, whereas the number of resilients increased. Undercontrol, in particular, was found to peak in early-to-middle adolescence. We also found substantial stability of personality types, because 73.5% of the adolescents had the same personality type across the 5 waves. Personality change was mainly characterized by 2 transitions: overcontrol → resiliency and undercontrol → resiliency. The transitional analyses implied that the resilient type serves more often as the end point of personality development in adolescence than do overcontrol and undercontrol. Analyses of the personality type trajectories also revealed that the majority of adolescents who change personality type across 5 years made only 1 transition. Study 2 revealed systematic differences between resilients and overcontrollers in anxiety. Stable resilients were less anxious over time than were stable overcontrollers. Further, change from overcontrol to the resilient type was accompanied by decreases in anxiety, whereas change from the resilient type to overcontrol was accompanied by an increase in anxiety. Similarly, systematic differences between personality types were found in the formation of intimate relationships. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Personality, Family History, and Competence in Early Adult Romantic Relationships.

The present investigation tested how well family characteristics and the personality traits assessed by the Multidimensional Personality Questionnaire (A. Tellegen, 1982) measured in late adolescence predict aspects of romantic relationships in early adulthood. Nurturant-involved parenting practices and personality traits were related to observed negative interactions and to couples' reports of relationship quality. These results from a prospective longitudinal study suggest that the origins of competence in romantic relationships can be found both in individual differences in personality (especially in negative emotionality) and in differences in developmental experiences. Discussion further develops an account of relationship success and dysfunction that integrates proximal factors, such as couple interactions, with more distal factors such as personality and socialization experiences.

Personality factors in college dropout.

An entire freshman class (N = 2149) at the University of Iowa was administered a personality and an intellectual ability test prior to their 1st academic year. 13 months later groups of 1st-year dropouts (DO) and nondropouts (NDO) were defined. Based upon a value-conformity hypothesis, it was predicted that DOs would be more assertive and less task-oriented. Intellectual ability was controlled as a factor in dropout by matching each DO with an NDO S having an identical ability score. Personality differences were studied at 3 ability levels and for the sexes separately. The results supported the hypothesis for both sexes but only at the high-ability level.

Personality disorder in older adults: Assessment challenges and strategies.

Might some older persons experienced as difficult by their health care providers be exhibiting signs of maladaptive personality functioning? Personality disorder may be a more significant problem among treatment-seeking older adults than was previously believed. Psychologists seeking to assess personality disorder must confront several challenges, including their own beliefs regarding personality and aging, criteria sets of uncertain validity for the older persons, and the limitations of current assessment tools. Empirically informed assessment of personality disorder in older adults may be enhanced by reviewing evidence regarding the prevalence, associated demographic and clinical features, and natural history of personality pathology across the life span. This review also describes how assessing personality disorder in older adults poses unique diagnostic difficulties and proposes practical strategies for evaluating this challenging client group.

Personality–relationship transaction in young adulthood.

Personality and social relationships were assessed twice across a 4-year period in a general population sample of 489 German young adults. Two kinds of personality–relationship transaction were observed. First, mean-level change in personality toward maturity (e.g., increase in Conscientiousness and decrease in Neuroticism) was moderated by the transition to partnership but was independent of other developmental transitions. Second, individual differences in personality traits predicted social relationships much better than vice versa. Specifically, once initial correlations were controlled for, Extraversion, Shyness, Neuroticism, self-esteem, and Agreeableness predicted change in various qualities of relationships (especially with friends and colleagues), whereas only quality of relationships with preschool children predicted later Extraversion and Neuroticism. Consequences for the transactional view of personality in young adulthood are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Impressions of Personality in Parkinson's Disease: Can Rehabilitation Practitioners See Beyond the Symptoms?

Objective: To explore rehabilitation practitioners' use of observable cues of personality to form accurate impressions of persons with Parkinson's disease. Participants: Ninety-nine practitioners from disciplines of occupational, physical, and speech therapy and nursing and medicine. Procedure: Participants viewed excerpts of videotaped interviews of 6 men and 6 women with mild-to-moderate Parkinson's disease and formed impressions of the targets' personality. Main Outcome Measure: NEO Five Factor Inventory personality test. Analysis: Brunswik lens model correlational analysis of the associations between expressive behavior and personality judgments. Results: Practitioners were accurate in judging Openness to Experience, Agreeableness, and Conscientiousness but were unable to detect interparticipant differences in levels of Extraversion and Neuroticism. Conclusion: Accuracy in judging some traits suggests that future research may identify interventions, such as sensitizing practitioners to valid behavioral cues or modifying contextual features, to maximize a practitioner's ability to understand a client's personality.

Personality differences in attempted suicide versus suicide in adults 50 years of age or older.

The authors tested hypotheses concerning personality differences in treatment-seeking suicide attempters (AT; n = 60) and a community sample of suicides (SU; n = 43) over age 50. On the basis of prior research, the authors hypothesized that SU would be lower in Neuroticism and Openness and higher in Conscientiousness. A 2-group (AT vs. SU) multivariate analysis of covariance with NEO Personality Inventory--Revised (Informant Version) domain scores as dependent variables revealed that SU were lower in Neuroticism and higher in Conscientiousness. The authors conclude that AT and SU in this age group can be distinguished on the basis of informant ratings of personality traits. These differences can inform risk detection.

Multidimensional structure of the Hypomanic Personality Scale.

The structure of the Hypomanic Personality Scale was explored in a sample of young adults (N = 884); resulting structures were validated on subsamples with measures of personality traits, internalizing symptoms, and externalizing behaviors. Hierarchical cluster analysis and estimates of general factor saturation suggested the presence of a weak general factor, as well as 3 subordinate clusters. The 3-cluster subscales (Social Vitality, Mood Volatility, and Excitement) were moderately correlated but conceptually distinct and were correlated in opposing patterns with a range of personality and psychopathology measures. Results show that cluster subscales suppress total score associations with validity measures. Recommendations are made to analyze Hypomanic Personality Scale data by subscale, and theoretical implications are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Personality variables in union-management relations.

To test the hypothesis that personalities of key figures have a significant impact upon the course of union-management relations at the plant level, quantitative data were gathered on the relationship in 33 tool-and-die shops. Each manager and each steward provided personality data (Guilford-Zimmerman) and judgments of best and poorest co-workers. A factor analysis of all possible intercorrelations showed a greater than chance expectancy of significant loadings of personality measures on the factors representing basic dimensions of the union-management relationship. Within limits set by such factors as technology and union policy, the personality of the top manager or the top union official may significantly modify the course of union-management interactions.

Universal Features of Personality Traits From the Observer's Perspective: Data From 50 Cultures.

To test hypotheses about the universality of personality traits, college students in 50 cultures identified an adult or college-aged man or woman whom they knew well and rated the 11,985 targets using the 3rd-person version of the Revised NEO Personality Inventory. Factor analyses within cultures showed that the normative American self-report structure was clearly replicated in most cultures and was recognizable in all. Sex differences replicated earlier self-report results, with the most pronounced differences in Western cultures. Cross-sectional age differences for 3 factors followed the pattern identified in self-reports, with moderate rates of change during college age and slower changes after age 40. With a few exceptions, these data support the hypothesis that features of personality traits are common to all human groups. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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.

Personality, self-estimated intelligence, and uses of music: A Spanish replication and extension using structural equation modeling.

This study replicates and extends a recent study on personality, intelligence and uses of music [Chamorro-Premuzic, T., & Furnham, A. (2007). Personality and music: Can traits explain how people use music in everyday life? British Journal of Psychology, 98, 175–185] using Spanish participants and structural equation modeling. Data from 245 university students showed that, in line with our hypotheses, individuals higher in Neuroticism were more likely to use music for emotional regulation (influencing their mood states), those higher in Extraversion were more likely to use music as background to other activities, and those higher in Openness were more likely to experience music in a cognitive or intellectual way. As predicted, self-estimates of intelligence were also linked to cognitive use of music, though not when individual differences were considered. On other hand, contrasting with initial predictions, Extraversion was positively rather than negatively linked to emotional use of music. Small incremental effects of gender (over personality) were also found on the emotional use of music. Results are discussed in regards to previous findings on personality traits as determinants of uses of music. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality traits change in adulthood: Reply to Costa and McCrae (2006).

In a response to comments by P. T. Costa, Jr., and R. R. McCrae (see record 2006-00818-002) on the current authors' original article (see record 2006-00818-001), the authors show that Costa and McCrae's writings on personality suggest a belief in immutability of personality traits. The authors agree with Costa and McCrae that new personality trait models that provide an accurate lower order structure of personality traits are needed and explain why the Revised NEO Personality Inventory is not the correct model for that purpose. The authors provide direct evidence refuting the hypothesis that personality traits change only because of biologically based intrinsic maturation. The authors present arguments supporting the contention that meta-analyses should be preferred to single longitudinal studies when drawing inferences about general patterns of personality development. Finally, the authors point out why the differences between their position and Costa and McCrae's are important. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Personality and Transformational and Transactional Leadership: A Meta-Analysis.

This study was a meta-analysis of the relationship between personality and ratings of transformational and transactional leadership behaviors. Using the 5-factor model of personality as an organizing framework, the authors accumulated 384 correlations from 26 independent studies. Personality traits were related to 3 dimensions of transformational leadership--idealized influence-inspirational motivation (charisma), intellectual stimulation, and individualized consideration--and 3 dimensions of transactional leadership--contingent reward, management by exception-active, and passive leadership. Extraversion was the strongest and most consistent correlate of transformational leadership. Although results provided some support for the dispositional basis of transformational leadership--especially with respect to the charisma dimension--generally, weak associations suggested the importance of future research to focus on both narrower personality traits and nondispositional determinants of transformational and transactional leadership.
