Assessing normal and abnormal personality functioning: strengths and weaknesses of self-report, observer, and performance-based methods

Assessing personality characteristics; distinguishing the boundaries between normal and abnormal functioning; identifying impairment in the domains of work, interpersonal relationships, and emotional state due to maladaptive personality traits; and translating these findings into effective, appropriate treatment interventions is a complicated endeavor. Valid, reliable conclusions about an individual's personality functioning and adjustment cannot be reached unless one has accurate information about that person's patterns of behavior, cognitions, emotions, and interpersonal relationships. I discuss strengths and weaknesses of assessment approaches utilizing explicit assessment methods, such as self-report measures and clinical interviews; information obtained from knowledgeable observers; and performance-based, implicit assessment methods such as the Rorschach Comprehensive System (Exner, 2003). In contrast to explicit methods of assessment, implicit methods can provide salient information about a personality construct whether or not individuals have accurately conceptualized that construct, have weighed how the construct describes them, are self-aware, and are willing to openly provide information relevant to that construct. I propose that the accuracy of conclusions about an individual's personality style, problems in adjustment, and treatment needs may be improved if conclusion are based on a multimethod assessment approach that incorporates information gathered using explicit assessment methods, information provided by significant others, and data from performance-based or implicit measures of personality.     

Personality traits and health‐risk behaviours in university students

Relations between personality and health‐risk behaviours in university undergraduates were examined using multiple measures of personality across multiple samples (N = 1151). Big Five personality variables, at both factor and facet levels, were used to predict three specific health‐risk behaviours: (a) tobacco consumption, (b) alcohol consumption and (c) speeding in an automobile. Our findings showed that low Conscientiousness and low Agreeableness were uniformly associated with this cluster of potentially health damaging behaviours. Extraversion was additionally associated with alcohol use. Interaction effects were found between Conscientiousness and Agreeableness on smoking and (for men only) on drinking. Other personality variables not centrally related to the Big Five, such as Risk‐Taking (high) and Integrity (low), were also implicated in the present health‐risk behaviours.

Is personality disorder inherited? An overview of the evidence

Genetic factors appear to be of considerable importance in determining normal variation in personality. This is suggested by family, twin, and adoption studies as well as by indirect findings based on animal and psychophysiological studies. In contrast, there is consistent evidence that the contribution of shared family environment is minimal. Despite difficulties in defining personality disorder, it appears that many types of personality disorder, in particular schizotypal personality disorder and antisocial personality disorder/criminality, are also influenced genetically. The genetic transmission of normal personality traits and disorder is most easily explained by the contribution of multiple genes of small effect rather than by single-gene inheritance. Recent advances in molecular genetics have led to the localization of genes of minor effect for some traits. This raises the possibility of detecting a molecular basis of traits and disorders such as personality and personality disorder.Anita Thapar is supported by a Research Training Fellowship from the Medical Research Council.     

Perceived strengths of urban girls and boys experiencing homelessness

Homelessness, with concomitant poverty and mobility, is often associated with multiple negative outcomes for school‐aged children; less is known about the positive characteristics of children experiencing homelessness. This study focused on understanding the mother‐perceived strengths of 50 elementary school‐aged children experiencing homelessness. Mothers typically identified multiple child strengths, even among children experiencing emotional or behavioural difficulties. These strengths included positive personality and behavioural characteristics, intelligence and academic achievement and positive physical attributes. Implications for intervention and further research are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Theodore Millon's Contributions to Conceptualizing Personality Disorders

We review Theodore Millon's contributions to conceptualizing personality disorders in contemporary clinical science and practice. Millon worked tirelessly across professional domains and theoretical orientations, developing a rich integrative theory of personality and its pathology, directly and indirectly impacting the evolving iterations of the Diagnostic and Statistical Manual of Mental Disorders (DSM–III through DSM–5), and advocating for the personality disorders through his contributions to cofounding the International Society for the Study of Personality Disorders and the Journal of Personality Disorders. We conclude with a closer look at Millon's final major contributions to conceptualizing personality disorders as well as the strengths and limitations of his approach.     

Making Rorschach interpretation as good as it can be

This article delineates six guidelines for enhancing the quality and utility of interpretations derived from the Rorschach inkblot method. These include (a) using all of the available structural, thematic, and behavioral data in arriving at interpretations; (b) focusing interpretive statements primarily on personality processes and drawing clinical conclusions and recommendations secondarily on the basis of identified personality processes; (c) addressing interpretations to both personality strengths and personality weaknesses to attend equally to adaptive capacities and maladaptive tendencies; (d) formulating and conveying interpretations at appropriate levels of certainty to distinguish clearly between probable fact and possible conjecture; (e) pursuing and expressing both nomothetic and idiographic implications of interpretations to the fullest possible extent, recognizing that personality is best described by considering both how people resemble and how they differ from each other; and (f) grounding the implications of interpretations in each respondent's cultural context to take adequate account of the mediation of cultural relativism between personality characteristics and their adaptive consequences.     

Borderline Personality Disorder in Adolescence Through the Lens of the Interview of Personality Organization Processes in Adolescence (IPOP-A): Clinical Use and Implications

Borderline personality disorder can be assessed in adolescence mainly through a dimensional approach that takes into account strengths and weaknesses of emerging personality patterns. Clinical interviews could help clinicians to gather information about adolescent’s functioning, fostering therapeutic alliance and promoting a mentalizing stance during the assessment of borderline adolescents. In this article, the Interview of Personality Organization Processes in Adolescence (IPOP-A) is presented through clinical case material to show its usefulness in clinical and research settings. The IPOP-A assesses an adolescent’s emerging personality along three dimensions: identity, quality of object relations and affect regulation. These dimensions are the core of borderline personality in adolescence.     

Tracking Fluctuations in Psychological States Using Social Media Language: A Case Study of Weekly Emotion

Personality psychologists are increasingly documenting dynamic, within-person processes. Big data methodologies can augment this endeavour by allowing for the collection of naturalistic and personality-relevant digital traces from online environments. Whereas big data methods have primarily been used to catalogue static personality dimensions, here we present a case study in how they can be used to track dynamic fluctuations in psychological states. We apply a text-based, machine learning prediction model to Facebook status updates to compute weekly trajectories of emotional valence and arousal. We train this model on 2895 human-annotated Facebook statuses and apply the resulting model to 303 575 Facebook statuses posted by 640 US Facebook users who had previously self-reported their Big Five traits, yielding an average of 28 weekly estimates per user. We examine the correlations between model-predicted emotion and self-reported personality, providing a test of the robustness of these links when using weekly aggregated data, rather than momentary data as in prior work. We further present dynamic visualizations of weekly valence and arousal for every user, while making the final data set of 17 937 weeks openly available. We discuss the strengths and drawbacks of this method in the context of personality psychology's evolution into a dynamic science. © 2020 European Association of Personality Psychology     

Strength balance and implicit strength measurement: New considerations for research on strengths of character

Jack of all trades, master of none seems apropos to character strengths. Research indicates that readily endorsed and intrinsically motivating strengths (i.e. signature strengths) are most useful in promoting well-being; improving less-developed strengths receives less emphasis. Unfortunately, that research focuses exclusively on explicit self-report. We tested whether strength balance (i.e. jack of all strengths) impacts well-being beyond mastering signature strengths by conducting a multivariate regression with signature strengths and strength balance predicting life satisfaction and psychological need (relatedness, competency, and autonomy) satisfaction. We also developed a novel, strength-based implicit association test (IAT) to complement explicit measurement. Our study (N?=?140 adults) results suggest that signature strengths and strength balance uniquely predicted greater well-being. Though our IAT possessed poor internal consistency, it provides valuable information regarding the design of future implicit measures of character strengths. Strength balance and implicit strength measurement may offer new opportunities to further understanding of personality and well-being.     

Personality Assessment in the Diagnostic Manuals: On Mindfulness,Multiple Methods,and Test Score Discontinuities

Recent controversies have illuminated the strengths and limitations of different frameworks for conceptualizing personality pathology (e.g., trait perspectives, categorical models), and stimulated debate regarding how best to diagnose personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), and in other diagnostic systems (i.e., the International Classification of Diseases, the Psychodynamic Diagnostic Manual). In this article I argue that regardless of how PDs are conceptualized and which diagnostic system is employed, multimethod assessment must play a central role in PD diagnosis. By complementing self-reports with evidence from other domains (e.g., performance-based tests), a broader range of psychological processes are engaged in the patient, and the impact of self-perception and self-presentation biases can be better understood. By providing the assessor with evidence drawn from multiple modalities, some of which provide converging patterns and some of which yield divergent results, a multimethod assessment compels the assessor to engage this evidence more deeply. The mindful processing that ensues can help minimize the deleterious impact of naturally occurring information processing bias and distortion on the part of the clinician (e.g., heuristics, attribution errors), bringing greater clarity to the synthesis and integration of assessment data.     

Gratitude,forgivingness, and well-being in adulthood: Tests of moderation and incremental prediction

Following recent guidelines for moral personality research, this study sought to provide insights into how moral personality traits influence well-being in adulthood. Using a large sample of Swiss adults (N?=?962), we examined the roles of gratitude and forgivingness on well-being in adulthood (assessed as positive affect, negative affect, optimism, pessimism, and satisfaction with life). Our results point to three primary findings. First, grateful and forgiving adults report greater well-being in adulthood and these effects are not moderated by age, gender, or marital status. Second, both traits uniquely predict well-being when controlling for each other, suggesting the importance of studying multiple moral personality variables. Third, these two traits largely remained significant predictors of well-being when controlling for the Big Five traits. Results are discussed with respect to their place within current directions in moral personality research as well as how they provide a foundation for future work.     

Disintegrated experience: the dissociative disorders revisited

We present proposed changes to the dissociative disorders section of the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders and review the concept of pathological and nonpathological dissociation, including empirical findings on the relations between trauma and dissociative phenomenology and between dissociation and hypnosis. The most important proposals include the creation of two new diagnostic entities, brief reactive dissociative disorder and transient dissociative disturbance, and the readoption of the criterion of amnesia for a multiple personality disorder diagnosis. We conclude that further work on dissociative processes will provide an important link between clinical and experimental approaches to human cognition, emotion, and personality.     

The Role of Character Strengths and Importance of Family on Mexican American College Students' Career Decision Self‐Efficacy

This study examined how character strengths and the importance of family influenced Mexican American college students' (N = 129) career decision self‐efficacy. Findings from a multiple regression analysis indicated that psychological grit and curiosity were significant predictors of career decision self‐efficacy. The authors discuss the importance of these findings and provide recommendations for future research.     

Character Strengths – Stability,Change, and Relationships with Well-Being Changes

Character strengths are positively valued personality traits that are assumed to be stable across time and situations, but also malleable due to cultivation or deliberate intervention. Also, studies showed that character strengths are robustly related to well-being. Consequently, character strengths have often been used in interventions aimed at increasing well-being. However, the stability of character strengths and the longitudinal relationships with well-being are widely unexplored: First, previous reports on the stability of character strengths have mainly focused on one assessment instrument only and second, they did not consider other indicators of stability (and malleability) besides rank-order stability, (i.e., mean-level stability). In this longitudinal study, we assessed character strengths and well-being at two time points and examined the stability and malleability of character strengths and the convergence of changes in character strengths and well-being by means of correlation analyses. Two samples (n₁ = 601, n₂ = 1162) completed different measures of character strengths and instruments for the assessment of well-being, ill-being, and health within up to three and a half years. Results showed that character strengths are stable over longer time periods (test-retest reliabilities ranging from r_tt = .60–.83) and that relationships between changes in strengths and well-being are highly parallel to what has been reported in cross-sectional studies (strongest relationships for zest, hope, curiosity, and love). Furthermore, results suggest that some strengths, most predominantly humor, but also spirituality and prudence might be more amenable for change than others. These results might bear important information for selecting character strengths in interventions.

     

4. Personality Profiles

ABSTRACT Chapter 4 discusses the origins of the Dodge Morgan case study and the circumstances of his assessments. We present findings in the contexts of both the five-factor model (FFM) and the life-story model (LSM). We interpret Personality Research Form scale scores within the five-factor structure in order to create Morgan's FFM personality profile, which is supplemented with Thematic Apperception Test (TAT) data. We structure his LSM profile from multiple evaluations, including his TAT protocol and his earliest memories; from autobiographical data, including his published writings; and from additional biographical sources. Finally, we discuss the strengths and limitations of each theory and profile construction method.     

Personality,health, and aging: prolegomenon for the next generation

The effect of personality characteristics on physical health continues to be an important topic in personality psychology, behavioral medicine, and health psychology. A more definitive methodological approach to the topic has evolved in recent years, emphasizing prospective designs, well-validated measures of personality, and unambiguous health outcomes. Further, this research is increasingly based on more detailed, physiologically plausible models of the possible mechanisms linking personality and health. Yet, one valuable perspective, life span development, has been relatively absent. As a guide to the next generation of studies on personality and health, we review conceptual and methodological issues, emphasizing the potential role of the life span perspective. We also illustrate these issues by reviewing recent reach on three personality characteristics studied as risk factors for physical disease—hostility, neuroticism, and optimism. The strengths of current personality and health research, recent developments in personality psychology, and the concepts and methods of life span approaches can be combined to construct a more complete and useful account of personality's effects on health and disease.     

Predicting high risk sexual behaviour in heterosexual and homosexual men: the roles of impulsivity and sensation seeking

Impulsivity and sexual sensation seeking were examined as personality correlates of high risk sexual behaviour — unprotected sex with multiple partners — in samples of heterosexual (n=112) and homosexual (n=104) men. Among heterosexuals, both personality variables were associated with frequency of unprotected sex but only sexual sensation seeking was associated with number of sex partners. Sexual sensation seeking also mediated the association between use of drugs other than alcohol and number of sex partners. Among homosexuals, no personality or substance use variables predicted high risk sexual behaviour. Implications of the findings for the study of determinants of sexual risk-taking are discussed.     

Personality Strengths as Resilience: A One‐Year Multiwave Study

We examined how personality strengths prospectively predict reactions to negative life events. Participants were 797 community adults from 42 countries. At five points over the course of 1 year, participants completed a series of questionnaires measuring seven personality strengths (hope, grit, meaning in life, curiosity, gratitude, control beliefs, and use of strengths), subjective well‐being, and frequency and severity of negative life events. Using hierarchical linear modeling with assessment periods nested within participants, results from lagged analyses found that only hope emerged as a resilience factor. To illustrate the importance of using appropriate lagged analyses in resilience research, we ran nonlagged analyses; these results suggest that all seven personality strengths moderated the effect of negative life events on subjective well‐being, with greater strengths associated with healthier outcomes. To provide evidence that personality strengths confer resilience, a prospective examination is needed with the inclusion of events and responses to them. The use of concurrent methodologies and analyses, which is the norm in psychology, often leads to erroneous conclusions. Hope, the ability to generate routes to reach goals and the motivation to use those routes, was shown to be particularly important in promoting resilience.     

Personality Traits Predict the Developmental Course of Externalizing: A Four‐Wave Longitudinal Study Spanning Age 17 to Age 29

The objective of the present study was to determine whether and how personality predicts the developmental course of externalizing problems, including antisocial behavior and substance dependence. In a large, population‐based longitudinal study (N = 1,252), the 11 personality traits assessed by the Multidimensional Personality Questionnaire were measured at age 17, and DSM diagnoses of adult antisocial behavior, alcohol dependence, and drug dependence were obtained at ages 17, 20, 24, and 29. We fit a quadratic multiple indicator latent growth model where the three diagnoses loaded onto an externalizing factor. This model fit the data well, and externalizing increased until it started to decline at age 24. High aggression and low control were the most significant predictors of the development of externalizing, with aggression playing a significant role in the development of externalizing across the 12‐year time span, and control predicting the development from age 17 to 24. The findings highlight the importance of considering the developmental course of externalizing in the context of personality and suggest that the specific personality traits of aggression and control might be targeted in externalizing prevention and intervention programs.     

Comparison of self-reports, reports by knowledgeable informants, and behavioral observation data

The strengths and weaknesses for the assessment of personality characteristics of self-reports, reports by knowledgeable informants, and measures based on behavioral observation data are discussed and compared It is suggested that measurement methods should be evaluated with respect to Loevinger's concept of structural validity The concept of structural validity is expanded to include evidence that the scores have properties paralleling the theoretical definition of the characteristic with respect to reliability over occasions, range of referent attributes sampled, and generality across situations or the specification of situation parameters Each of the methods is evaluated for its potential to construct measures with structural validity for different models of constructs The methods are also discussed in relation to several other common threats to validity, specifically, threats stemming from the respondent, from the investigator, and from sampling errors It is likely that demonstrations of convergence between these methods will be possible for some but not all constructs It is also suggested that the examination of structural validity will contribute to the evolution and refinement of constructs appropriate for interactionist theories
