Is “maturing out” of problematic alcohol involvement related to personality change?

Problematic alcohol involvement typically peaks in the early 20s and declines with age. This maturing out of alcohol involvement is usually attributed to individuals attaining adult statuses incompatible with heavy drinking. Nevertheless, little is known about how changes in problematic alcohol use during emerging/early adulthood relate to changes in etiologically relevant personality traits that also change during this period. This study examined the relation between changes in problematic alcohol involvement and personality (measures of impulsivity, neuroticism, and extraversion) from ages 18 to 35 in a cohort of college students (N = 489) at varying risk for alcohol use disorders. Latent growth models indicated that both normative and individual changes in alcohol involvement occur between ages 18 and 35 and that these changes are associated with changes in neuroticism and impulsivity. Moreover, marital and parental role statuses did not appear to be third-variable explanations of the associated changes in alcohol involvement and personality. Findings suggest that personality change may be an important mechanism in the maturing-out effect. (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)     

Genetic and environmental influences on personality trait stability and growth during the transition to adulthood: A three-wave longitudinal study.

During the transition to adulthood individuals typically settle into adult roles in love and work. This transition also involves significant changes in personality traits that are generally in the direction of greater maturity and increased stability. Competing hypotheses have been offered to account for these personality changes: The intrinsic maturation hypothesis suggests that change trajectories are endogenous, whereas the life-course hypothesis suggests that these changes occur because of transactions with the social environment. This study investigated the patterns and origins of personality trait changes from ages 17 to 29 using 3 waves of Multidimensional Personality Questionnaire data provided by twins. Results suggest that (a) trait changes were more profound in the first relative to the second half of the transition to adulthood; (b) traits tend to become more stable during the second half of this transition, with all the traits yielding retest correlations between .74 and .78; (c) Negative Affectivity declined over time, and Constraint increased over time; minimal change was observed on agentic or communal aspects of Positive Emotionality; and (d) both genetic and nonshared environmental factors accounted for personality changes. Overall, these genetically informed results support a life-course perspective on personality development during the transition to adulthood.

Narrating personality change.

The present research investigated the longitudinal relations between personality traits and narratives. Specifically, the authors examined how individual differences in 170 college students' narratives of personality change (a) were predicted by personality traits at the beginning of college, (b) related to actual changes and perceived changes in personality traits during college, and (c) related to changes in emotional health during college. Individual differences in narratives of personality trait change told in the 4th year of college fell into 2 dimensions: affective processing, characterized by positive emotions, and exploratory processing, characterized by meaning making and causal processing. Conscientious, open, and extraverted freshmen told exploratory stories of change as seniors. Emotionally healthy freshmen told stories of change that were high in positive affect. Both positive affective and exploratory stories corresponded to change in emotional stability and conscientiousness during college above and beyond the effects of perceived changes in these traits. In addition, both positive affective and exploratory narratives corresponded to increases in emotional health during college independent of the effects of changes in personality traits. These findings improve our understanding of how individuals conceptualize their changing identity over time. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Work experiences and personality development in young adulthood.

This longitudinal study provides an analysis of the relationship between personality traits and work experiences with a special focus on the relationship between changes in personality and work experiences in young adulthood. Longitudinal analyses uncovered 3 findings. First, measures of personality taken at age 18 predicted both objective and subjective work experiences at age 26. Second, work experiences were related to changes in personality traits from age 18 to 26. Third, the predictive and change relations between personality traits and work experiences were corresponsive: Traits that "selected" people into specific work experiences were the same traits that changed in response to those same work experiences. The relevance of the findings to theories of personality development is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The stability of personality traits in individuals with borderline personality disorder.

Although stability and pervasive inflexibility are general criteria for Diagnostic and Statistical Manual of Mental Disorders, 4th edition (American Psychiatric Association, 1994) personality disorders (PDs), borderline PD (BPD) is characterized by instability in several domains, including interpersonal behavior, affect, and identity. The authors hypothesized that such inconsistencies notable in BPD may relate to instability at the level of the basic personality traits that are associated with this disorder. Five types of personality trait stability across 4 assessments over 6 years were compared for BPD patients (N = 130 at first interval) and patients with other PDs (N = 302). Structural stability did not differ across groups. Differential stability tended to be lower for 5-factor model (FFM) traits in the BPD group, with the strongest and most consistent effects observed for Neuroticism and Conscientiousness. Growth curve models suggested that these 2 traits also showed greater mean-level change, with Neuroticism declining faster and Conscientiousness increasing faster, in the BPD group. The BPD group was further characterized by greater individual-level instability for Neuroticism and Conscientiousness in these models. Finally, the BPD group was less stable in terms of the ipsative configuration of FFM facet-level profiles than was the other PD group over time. Results point to the importance of personality trait instability in characterizing BPD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Do personality problems improve during psychodynamic supportive–expressive psychotherapy? Secondary outcome results from a randomized controlled trial for psychiatric outpatients with personality disorders.

Studies involving patients with personality disorders (PDs) have not focused on improvement of core aspects of the PD. The authors examined changes in quality of object relations, interpersonal problems, psychological mindedness, and personality traits in a sample of 156 patients with Diagnostic and Statistical Manual of Mental Disorders (4th ed.) PD diagnoses being randomized to either manualized or nonmanualized dynamic psychotherapy. Effect sizes adjusted for symptomatic change and reliable change indices were calculated. The authors found that both treatments were equally effective at reducing personality pathology. Only in neuroticism did the nonmanualized group do better during the follow-up period. The largest improvement was found in quality of object relations. For the remaining variables, only small and clinically insignificant magnitudes of change were found.

Striking the (Im)proper balance between scientific advances and clinical utility: Commentary on the DSM–5 proposal for personality disorders.

We review briefly the contributions of Skodol et al. (2011a, 2011b), Pincus (2011), and Widiger (2011) describing and critiquing the proposed changes in the assessment of personality and personality disorders for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–5). Despite the hard work of the DSM–5 Work Group to date, there are shortcomings and areas of controversy in the current proposal that demand further attention and change. We discuss the controversy in the broader context of the DSM over the past 30 years. In addressing specific problems, we focus on the limitations of the proposed system for assessing traits (even as we endorse the movement toward dimensional assessment of personality) and the difficulties posed by the current “hybrid” model that attempts to include both traits and types. In moving forward, we suggest greater emphasis on decision making regarding the presence and severity of any personality disorder (understood on the basis of generalized failures in adaptation) and greater flexibility in identifying the variants of personality disorders in order to accommodate both traits and types more inclusively during this transition toward dimensional approaches to assessment.

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.

Method factors in changes associated with psychotherapy.

This study investigated the factorial structure of changes concomitant with client-centered therapy. Most of the variables were differences obtained subtracting the pretherapy scores from the corresponding post-therapy scores of each of 93 clients. The 1st 4 factors seem to reflect: change in favorableness of client self-evaluation, change in adequacy ratings based on the TAT, therapist's perception of change, and change on Hs and Hy from the MMPI. The 5th factor was length of therapy. Of these orthogonal factors, the 1st 4 are seen as method factors, each being associated primarily with an observer-instrument combination. As measured, the changes associated with short psychotherapy cannot be adequately represented by a single global rating or by scores for personality traits defined either broadly or narrowly.

Personality trait development from age 12 to age 18: Longitudinal, cross-sectional and cross-cultural analyses.

Three studies were conducted to assess mean level changes in personality traits during adolescence. Versions of the Revised NEO Personality Inventory (P. T. Costa, Jr., & R. R. McCrae, 1992a) were used to assess the 5 major personality factors. A 4-year longitudinal study of intellectually gifted students (N = 230) was supplemented by cross-sectional studies of nonselected American (N = 1,959) and Flemish (N = 789) adolescents. Personality factors were reasonably invariant across ages, although rank-order stability of individual differences was low. Neuroticism appeared to increase in girls, and Openness to Experience increased in both boys and girls; mean levels of Extraversion, Agreeableness, and Conscientiousness were stable. Results extend knowledge of the developmental curve of penalty traits backward from adulthood and help bridge the gap with child temperament studies.

Too much of a good thing: Curvilinear relationships between personality traits and job performance.

The relationships between personality traits and performance are often assumed to be linear. This assumption has been challenged conceptually and empirically, but results to date have been inconclusive. In the current study, we took a theory-driven approach in systematically addressing this issue. Results based on two different samples generally supported our expectations of the curvilinear relationships between personality traits, including Conscientiousness and Emotional Stability, and job performance dimensions, including task performance, organizational citizenship behavior, and counterproductive work behaviors. We also hypothesized and found that job complexity moderated the curvilinear personality–performance relationships such that the inflection points after which the relationships disappear were lower for low-complexity jobs than they were for high-complexity jobs. This finding suggests that high levels of the two personality traits examined are more beneficial for performance in high- than low-complexity jobs. We conclude by discussing the implications of these findings for the use of personality in personnel selection. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stability and change of personality across the life course: The impact of age and major life events on mean-level and rank-order stability of the Big Five.

Does personality change across the entire life course, and are those changes due to intrinsic maturation or major life experiences? This longitudinal study investigated changes in the mean levels and rank order of the Big Five personality traits in a heterogeneous sample of 14,718 Germans across all of adulthood. Latent change and latent moderated regression models provided 4 main findings: First, age had a complex curvilinear influence on mean levels of personality. Second, the rank-order stability of Emotional Stability, Extraversion, Openness, and Agreeableness all followed an inverted U-shaped function, reaching a peak between the ages of 40 and 60 and decreasing afterward, whereas Conscientiousness showed a continuously increasing rank-order stability across adulthood. Third, personality predicted the occurrence of several objective major life events (selection effects) and changed in reaction to experiencing these events (socialization effects), suggesting that personality can change due to factors other than intrinsic maturation. Fourth, when events were clustered according to their valence, as is commonly done, effects of the environment on changes in personality were either overlooked or overgeneralized. In sum, our analyses show that personality changes throughout the life span, but with more pronounced changes in young and old ages, and that this change is partly attributable to social demands and experiences.

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)     

Development of personality in early and middle adulthood: Set like plaster or persistent change?

Different theories make different predictions about how mean levels of personality traits change in adulthood. The biological view of the Five-factor theory proposes the plaster hypothesis: All personality traits stop changing by age 30. In contrast, contextualist perspectives propose that changes should be more varied and should persist throughout adulthood. This study compared these perspectives in a large (N=132,515) sample of adults aged 21-60 who completed a Big Five personality measure on the Internet. Conscientiousness and Agreeableness increased throughout early and middle adulthood at varying rates; Neuroticism declined among women but did not change among men. The variety in patterns of change suggests that the Big Five traits are complex phenomena subject to a variety of developmental influences.

Do changes in drinking motives mediate the relation between personality change and “maturing out” of problem drinking?

Recent research has indicated that developmental changes in the personality traits of neuroticism and impulsivity correlate with changes in problem drinking during emerging and young adulthood. However, it remains unclear what potential mechanisms, or mediators, could account for these associations. Drinking motives, particularly drinking to regulate negative affect (drinking to cope) and to get “high” or “drunk” (drinking for enhancement), have been posited to mediate the relationship between personality and drinking problems. Recent work indicates that changes in drinking motives parallel changes in alcohol involvement from adolescence to young adulthood. The present study examined changes in drinking motives (i.e., coping and enhancement) as potential mediators of the relation between changes in personality (impulsivity and neuroticism) with changes in alcohol problems in emerging and young adulthood. Analyses were based on data collected from a cohort of college students (N = 489) at varying risk for alcohol use disorders from ages 18 to 35. Parallel process latent growth modeling indicated that change in coping (but not enhancement) motives specifically mediated the relation between changes in neuroticism and alcohol problems as well as the relation between changes in impulsivity and alcohol problems. Findings suggest that change in coping motives is an important mechanism in the relation between personality change and the “maturing out” of problematic alcohol involvement.

Cohort differences in Big Five personality factors over a period of 25 years.

The notion of personality traits implies a certain degree of stability in the life span of an individual. But what about generational effects? Are there generational changes in the distribution or structure of personality traits? This article examines cohort changes on the Big Five personality factors Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience, among first-year psychology students in the Netherlands, ages 18 to 25 years, between 1982 and 2007. Because measurement invariance of a personality test is essential for a sound interpretation of cohort differences in personality, we first assessed measurement invariance with respect to cohort for males and females separately on the Big Five personality factors, as measured by the Dutch instrument Five Personality Factors Test. Results identified 11 (females) and 2 (males) biased items with respect to cohort, out of a total of 70 items. Analyzing the unbiased items, results indicated small linear increases over time in Extraversion, Agreeableness, and Conscientiousness and small linear decreases over time in Neuroticism. No clear patterns were found on the Openness to Experience factor. Secondary analyses on students from 1971 to 2007 of females and males of different ages together revealed linear trends comparable to those in the main analyses among young adults between 1982 onward. The results imply that the broad sociocultural context may affect personality factors. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Long-term correlated change in personality traits in old age.

The present study examines long-term correlated change in personality traits in old age across a time period of 12 years. Data from the Interdisciplinary Study on Adult Development were used to investigate different aspects of personality change and stability. The sample consisted of 300 adults ranging from 60 to 64 years of age at Time 1. Personality was measured with the NEO Five-Factor Inventory. Longitudinal structural stability, differential stability, change in interindividual differences, mean-level change, and correlated change of the 5 personality traits were examined utilizing structural equation modeling. After having established strict measurement invariance, factor variances in Openness to Experience and Conscientiousness were found to be different across testing occasions, implying variant covariation patterns over time. Stability coefficients were around .70, indicating high but not perfect differential stability. The amount of interindividual differences increased with respect to Openness to Experience and Conscientiousness. Both mean-level change and stability in personality were observed. Eventually, except for Neuroticism, a number of medium effect-sized correlations among changes in personality traits emerged, implying that personality changes share a substantial amount of commonality.

A meta-analysis of normal and disordered personality across the life span.

Debate continues about whether personality, both normal and disordered, can change significantly or is mainly stable across the life span. One issue that receives little attention is the degree to which personality stability coefficients may be influenced by attenuation due to measurement error. The current meta-analysis examines the data from recent research on personality stability, reporting both uncorrected and corrected stability coefficients. Attenuation due to measurement error was found to cause a significant reduction in personality stability coefficients, raising the possibility that some studies may conflate personality change with measurement error. Overall, corrected stability coefficients suggested that the stability of personality across adulthood is high, with only modest change. By contrast, personality during childhood is significantly more changeable. Both normal personality and personality disorders were highly stable across the life span, and patients in therapy experienced no more personality change than did nonpatients. Cross-cultural comparisons suggested relatively similar levels of personality stability cross-culturally, although personality stability among people in South Pacific nations is slightly lower than among those in the United States, Canada, or European nations.
