Introduction to the special issue on personality and psychopathology.

The goal of this Special Issue is to enhance this reintegration of normal-range personality and abnormal psychology, 30 years after they were split apart. The articles in the Issue examine the topic from a variety of approaches, but each of them addresses the central problem of how normal-range individual differences are related to abnormal behavior. Seven of these articles examine personality in relation to specific types of psychopathology: personality disorders, alcoholism and antisocial personality, mood and anxiety disorders, dissociative disorders, somatoform disorders, eating disorders, and schizophrenia. It is impossible to summarize the wealth of findings that are contained in these articles; each deserves to be examined carefully. However, we can note some general conclusions here. First, it is abundantly clear that personality traits and psychopathological disorders are, in fact, empirically related. Second, although the observed relations tend to be orderly and psychologically meaningful, they also are relatively nonspecific. That is, one does not see a one-to-one correspondence between a given trait and a specific disorder; rather, each of the extensively studied traits is associated with several diagnostic categories. Third, due to a paucity of relevant data, the nature of these observed relations is still largely unclear. Several different explanatory models have been proposed, and each has received at least suggestive support in the literature. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hospital practice: Psychology's call to action.

The general public has recently made demands for continuity of care in psychological services from outpatient settings to inpatient facilities and back. These demands plus 3 economic and structural modifications within the nation's health-care arena, including the incursion of for-profit health-care corporations into the health delivery industry, the 1985 Joint Commission of Accreditation of Hospitals decision to include nonphysician providers on hospital medical staffs, and the 1990 California Supreme Court Decision (CAPP v. Rank) ensuring full medical staff participation by California psychologists, have opened the doors to the independent practice of psychology in hospitals, rehabilitation centers, nursing homes, and day treatment facilities. This article presents current professional realities for psychologists in hospitals and health-care settings and reviews the work of the American Psychological Association in support of hospital independent practice.

Personality traits across cultures and research on obedience.

Comments on an article by Twenge (see record 2008-19206-004) on the issue of psychological traits that may differ with culture and ethnicity in discussing the partial replication of Milgram’s obedience research (Burger, January 2009) (see record 2008-19206-001). But since a major stimulus for Milgram’s research was the destruction of European Jewry (Benjamin & Simpson, January 2009 (see record 2008-19206-002); Blass, 2009 (see record 2008-19206-006)), what about the “elephant in the room” of differences in European national groups on obedience, aggression, locus of control, and related factors? The five-factor model as applied across cultures offers a way of looking at European national differences in personality (Allik & McCrae, 2004). The results can be used to explore the possibility that personality traits that may be related to obedience might differ partly along cultural lines, with the considerable caveats that such traits probably change over time and generations, are subject to situational and historical variables, and interact with individual differences. The emphasis on situational determinants in discussions of the Milgram paradigm and its partial replication by Burger (2009) should not obscure possible cultural factors. Cultural factors in obedience to authority are worthy of further exploration. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

The search for dimensional structure differences between normality and abnormality: A statistical review of published data on personality and psychopathology.

A statistical review of published data for 37 personality and psychopathology inventories was conducted to determine whether there are dimensional structure differences between clinical and nonclinical respondents. Correlation and factor-loading matrices from multiscale inventories and from specialized measures were tested for structural invariance across populations. There was relatively consistent evidence for high levels of similarity between normal and abnormal populations both in the number of factors that exist in the data matrices and in the factor patterns. The dimensional universes of normality and abnormality are apparently the same, at least according to data derived from contemporary assessment instruments. Categorical-taxonic differences between clinical and nonclinical populations, which were not examined, may nevertheless exist within contexts of dimensional structure similarity.

Male and female subjects in personality research.

Though studies have consistently demonstrated psychological differences between males and females, a review of published research indicated how little this finding influenced the selection of Ss for studies or the interpretation of results. A plea is made to include as easy a measure to obtain as the sex variable in the design. From Psyc Abstracts 36:02:2AF82C. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Bridging psychology and biology with animal research.

Comments on the article by S. M. Kosslyn et al (see record 2002-12932-001), which advocated combining group-based research and individual differences research to illuminate the links between psychology and biology. The authors agree that the study of individual differences is vital for uncovering processes that have hitherto remained obscured by relying too heavily on group-level approaches, and commend their multilevel, multidisciplinary approach to this important topic. However, they believe that Kosslyn et al should have given more attention to one of the most promising avenues for pursuing their multilevel approach--comparative research. The authors suggest that, although Kosslyn et al did refer to animal studies, they did not sufficiently emphasize the potential contribution of animal research.

Master's programs in industrial/organizational psychology: Current status and a call for action.

Reviews published and unpublished sources to describe characteristics of terminal master's programs in industrial/organizational (I/O) psychology and argues that systematic attention should be paid to issues of education, employment, and professional identity for these master's graduates. The 55 or more programs represent a 3-fold increase in listings in less than a decade. In psycholoy departments, programs enrolled 59% of new I/O graduate students and awarded 67% of terminal graduate degrees during a 1-yr period. Important characteristics include length (about 2.5 yrs), many part-time and employed students, applied focus, emphasis on both industrial and organizational topics, but emphasis on either "psychology core" or technical I/O training. Most graduates find private sector employment, apparently moving away from organized I/O psychology. Implications for the profession are discussed.

Relations between personality and coping: A meta-analysis.

Personality may directly facilitate or constrain coping, but relations of personality to coping have been inconsistent across studies, suggesting a need for greater attention to methods and samples. This meta-analysis tested moderators of relations between Big Five personality traits and coping using 2,653 effect sizes drawn from 165 samples and 33,094 participants. Personality was weakly related to broad coping (e.g., Engagement or Disengagement), but all 5 traits predicted specific strategies. Extraversion and Conscientiousness predicted more problem-solving and cognitive restructuring, Neuroticism less. Neuroticism predicted problematic strategies like wishful thinking, withdrawal, and emotion-focused coping but, like Extraversion, also predicted support seeking. Personality more strongly predicted coping in young samples, stressed samples, and samples reporting dispositional rather than situation-specific coping. Daily versus retrospective coping reports and self-selected versus researcher-selected stressors also moderated relations between personality and coping. Cross-cultural differences were present, and ethnically diverse samples showed more protective effects of personality. Richer understanding of the role of personality in the coping process requires assessment of personality facets and specific coping strategies, use of laboratory and daily report studies, and multivariate analyses.

Education for research in psychology.

A report of a seminar held at Estes Park, Colorado, July 28-August 22, 1958, sponsored by the Education and Training Board of the American Psychological Association. The purpose of the seminar was "to provide information which would aid institutions giving graduate degrees in psychology in examining and improving their programs for training research men." Major sections are: (a) How Research Gets Done; (b) Formal Aspects of Graduate Training (Statistics, Other Tool Subjects, Breadth of Scholarship, Role of Theory in Research, Standardization), (c) Development of the Individual (Selection, Motivation, Apprenticeship); (d) Summing Up. Research is "learned by doing and taught mainly by contagion. Research must first be going on if there is to be research training… . Apprenticeship is, we believe, the most important part of education for research in psychology; the professor who hires a graduate student as a research assistant takes on the primary teaching responsibility for that student, a responsibility which both he and his department must recognize." Opposition is expressed to standardizing training programs for research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Need for cognition, task difficulty, and the formation of performance expectancies.

In the present article, the authors analyze how performance expectancies are generated and how they affect actual performance. The authors predicted that task difficulty would affect performance expectancies only when cognitive motivation (i.e., need for cognition [NFC]) and cognitive capacity are high. This should be the case because analyzing task difficulty is a process requiring cognitive capacity as well as cognitive motivation. The findings supported the expected NFC × Difficulty interaction for the formation of performance expectancies (Study 1, Study 2), but only when cognitive capacity was high (Study 2). The authors also predicted that expectancies would affect actual performance only if the task is difficult and if task difficulty is taken into account when the expectancy is generated. This hypothesis was supported: Significant relations between performance expectancies and actual performance were found only for difficult tasks and for participants higher in NFC. Studies 5 and 6 showed clear evidence that the NFC × Difficulty interaction could not be explained by differences in the use of task-specific self-concepts. The findings were robust across academic, social, and physical tasks. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Proposed changes in personality and personality disorder assessment and diagnosis for DSM-5 Part I: Description and rationale.

A major reconceptualization of personality psychopathology has been proposed for DSM-5 that identifies core impairments in personality functioning, pathological personality traits, and prominent pathological personality types. A comprehensive personality assessment consists of four components: levels of personality functioning, personality disorder types, pathological personality trait domains and facets, and general criteria for personality disorder. This four-part assessment focuses attention on identifying personality psychopathology with increasing degrees of specificity, based on a clinician's available time, information, and expertise. In Part I of this two-part article, we describe the components of the new model and present brief theoretical and empirical rationales for each. In Part II, we will illustrate the clinical application of the model with vignettes of patients with varying degrees of personality psychopathology, to show how assessments might be conducted and diagnoses reached.

Age differences in big five behavior averages and variabilities across the adult life span: Moving beyond retrospective, global summary accounts of personality.

In 3 intensive cross-sectional studies, age differences in behavior averages and variabilities were examined. Three questions were posed: Does variability differ among age groups? Does the sizable variability in young adulthood persist throughout the life span? Do past conclusions about trait development, based on trait questionnaires, hold up when actual behavior is examined? Three groups participated: young adults (18–23 years), middle-aged adults (35–55 years), and older adults (65–81 years). In 2 experience-sampling studies, participants reported their current behavior multiple times per day for 1- or 2-week spans. In a 3rd study, participants interacted in standardized laboratory activities on 8 occasions. First, results revealed a sizable amount of intraindividual variability in behavior for all adult groups, with average within-person standard deviations ranging from about half a point to well over 1 point on 6-point scales. Second, older adults were most variable in Openness, whereas young adults were most variable in Agreeableness and Emotional Stability. Third, most specific patterns of maturation-related age differences in actual behavior were more greatly pronounced and differently patterned than those revealed by the trait questionnaire method. When participants interacted in standardized situations, personality differences between young adults and middle-aged adults were larger, and older adults exhibited a more positive personality profile than they exhibited in their everyday lives.

Factors underlying expectancies of success and achievement: The influential roles of need for cognition and general or specific self-concepts.

It has been assumed that task-specific self-concepts are more important than general self-concepts in determining expectancies of success and subsequent achievement. The authors argue here that the influence varies depending on need for cognition (NFC). Findings from Study 1 (N = 104) showed that expectancies of success in an academic task could be predicted from specific self-concept for individuals with a high NFC and from general self-concept for individuals with a low NFC. In Study 2 (N = 193), where cognitive load was manipulated, given a high cognitive load, only general self-concept was predictive of success expectancies, independent of NFC. In Study 3 (N = 197), given a high relevance of correct expectancy ratings, only specific self-concept was predictive of expectancies and actual achievement, independent of NFC. In Studies 4 and 5, the results from Study 1 concerning the prediction of expectancies (as well as achievement) reappeared in a physical and a social domain.

Externalizing and Internalizing Subtypes of Combat-Related PTSD: A Replication and Extension Using the PSY-5 Scales.

This study replicated and extended prior findings of internalizing and externalizing subtypes of posttraumatic response (M. W. Miller, J. L. Greif, & A. A. Smith, 2003). Cluster analyses of the Minnesota Multiphasic Personality Inventory-2 Personality Psychopathology-Five (MMPI-2 PSY-5; A. R. Harkness, J. L. McNulty, Y. S. Ben-Porath, 1995) profiles obtained from 736 veterans with posttraumatic stress disorder (PTSD) partitioned the sample into a low pathology cluster defined by personality scores in the normal range, an externalizing cluster characterized by low constraint and high negative emotionality, and an internalizing cluster with high negative emotionality and low positive emotionality. Externalizers showed the highest rates of alcohol-related and antisocial personality disorders; internalizers, the highest rates of panic and major depressive disorder. These findings support the development of a personality-based typology of posttraumatic response designed to account for heterogeneity in the expression of PTSD and associated psychopathology.

Paul Meehl: Past and future lessons for the field.

Paul Everett Meehl (1920-2003) was an intellectual giant who made important contributions to several fields of thought. The present special section focuses on his contributions to psychopathology, personality, and methods of psychological inquiry. The editors identified six specific topic areas within these broad domains and invited a specialist on each topic to write a discussion. These authors were invited to review Meehl's contributions and clarify their historical significance and current relevance. In addition, two authors contributed personal perspectives on Meehl, revealing that Meehl profoundly affected psychological science by routes other than his publications and formal talks. Rather, his voluminous correspondence and his personal relationships allowed him to engage numerous colleagues in his passionate pursuit of ideas and insights.

A Dog's Got Personality: A Cross-Species Comparative Approach to Personality Judgments in Dogs and Humans.

This research offers a blueprint for how a cross-species comparative approach can be realized empirically. In a single design, parallel procedures and instruments were used in 2 species, dogs (Canis familiaris) and humans (Homo sapiens), to test whether personality differences exist and can be judged in dogs as accurately as in humans. Personality judgments of humans and dogs were compared on 3 accuracy criteria: internal consistency, consensus, and correspondence. Results showed that, on all 3 criteria, judgments of dogs were as accurate as judgments of humans. These findings are consistent with the evolutionary continuity hypothesis and suggest an important conclusion not widely considered by either personality or animal researchers: Personality differences do exist and can be measured in animals other than humans.

Relationship of personality to performance motivation: A meta-analytic review.

This article provides a meta-analysis of the relationship between the 5-factor model of personality and 3 central theories of performance motivation (goal-setting, expectancy, and self-efficacy motivation). The quantitative review includes 150 correlations from 65 studies. Traits were organized according to the 5-factor model of personality. Results indicated that Neuroticism (average validity=-.31) and Conscientiousness (average validity=.24) were the strongest and most consistent correlates of performance motivation across the 3 theoretical perspectives. Results further indicated that the validity of 3 of the Big Five traits--Neuroticism, Extraversion, and Conscientiousness--generalized across studies. As a set, the Big 5 traits had an average multiple correlation of .49 with the motivational criteria, suggesting that the Big 5 traits are an important source of performance motivation.
