Personality development in emerging adulthood: integrating evidence from self-ratings and spouse ratings

The authors examined self-ratings and spouse ratings in a young adult newlywed sample across a 2-year interval. Rank-order stability correlations were consistently high and did not differ across the 2 types of ratings. As expected, self-ratings showed significant increases in conscientiousness and agreeableness--and declines in neuroticism/negative affectivity--over time. Spouse ratings yielded a very different pattern, however, showing significant decreases in conscientiousness, agreeableness, extraversion, and openness across the study interval. Spouse ratings also showed evidence of a "honeymoon effect," such that they tended to be more positive than self-ratings at Time 1. This effect had dissipated by the 2nd assessment; in fact, the spouse ratings tended to be more negative at Time 2. Analyses of individual-level change revealed little convergence between self- and spouse-rated change, using both raw change scores and reliable change index scores. Finally, correlational and regression analyses indicated that changes in spouse ratings were significantly associated with changes in marital satisfaction; in contrast, changes in self-ratings essentially were unrelated to marital satisfaction. These results highlight the value of collecting multimethod data in studies of adult personality development.     

The NEO-PI-3: a more readable revised NEO Personality Inventory

Use of the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992) in adolescent samples has shown that a few respondents have difficulty with a subset of items. We identified 30 items that were not understood by at least 2% of adolescent respondents and 18 additional items with low item-total correlations, and we wrote 2 trial replacement items for each. We used self-report and observer rating data from 500 respondents aged 14 to 20 to select replacement items. The modified instrument retained the intended factor structure and showed slightly better internal consistency, cross-observer agreement, and readability (Flesch-Kincaid grade level = 5.3). The NEO-PI-3 appears to be useful in high school and college samples and may have wider applicability to adults as well.     

The NEO Personality Inventory: Using the Five-Factor ModeI in Counseling

Personality psychologists have recently concluded that five major dimensions account for most individual differences in personality traits. The NEO Personality Inventory (NEO-PI) is a concise measure of this Five-Factor Model and of some of the important traits that define the factors. Characteristics of the test, features for administration and scoring, and studies of reliability, stability, and validity are summarized. The NEO-PI may be particularly appropriate for use in counseling because it is brief, nonpsychopathological in content, and sensitive to client strengths as well as weaknesses. We suggest several ways in which the counselor can learn how to use the NEO-PI effectively.     

Reliability of informant ratings and spouse similarity based on the Temperament and Character Inventory

A cohort of 136 Swedish spouse pairs rated themselves and each other with the Temperament and Character Inventory. The data allowed assessment of the reliability of ratings by knowledgeable informants compared to self-rating for this personality test. The reliability of the informant rating was in the expected range, with an average correlation of .58. Agreement was slightly higher for the Temperament dimensions than for the Character dimensions. Additionally, the design allowed evaluation of the similarity between husbands and wives across the seven dimensions measured by the TCI. Correlations between spouses in self-reports were very low for Temperament, with only Harm Avoidance having a statistically significant correlation (.22, p < .05). On the other hand, all three Character dimensions were significantly correlated. These results support the conceptualization of Temperament and Character as separate components of personality. The results are consistent with previous reports on the personality of spouse pairs.     

Predicting Supervisor Ratings of Job Performance Using the NEO Personality Inventory

The resurging interest in identifying personality predictors of job performance has led researchers to use the five-factor model of personality as an important conceptual tool. Two recent meta-analyses illustrated the potential predictive power of the model within an employment context. In this study, we evaluated the relations between a well-validated self-report measure of the five-factor model and supervisor ratings of performance. Fifty-two women and 159 men completed the NEO Personality Inventory (Costa & McCrae, 1985) and were independently rated on various performance dimensions by their supervisors. Scores on the Conscientiousness scales correlated with all the performance ratings over this diverse number of occupational groups. Low Neuroticism and high Extraversion scores also predicted high performance. Low straightforwardness (a facet of agreeableness) was associated with ability to accomplish work-related goals and to adapt to changing work conditions. The results support the utility of the five-factor model as a predictor of job performance.     

Maternal perceptions and adolescent self-esteem: a six-year longitudinal study

A six-year longitudinal study investigated the development of self-esteem in relation to mother's child-rearing attitudes, role satisfaction, and perceived temperament of the child. Participants were two age cohorts of girls and boys from the Cardiovascular Risk in Young Finns study, being 6 (n = 416) and 9 years old (n = 408) at the beginning of the study (baseline). Scores regarding mother's hostile child-rearing attitudes, mother's low role satisfaction, and maternal perceptions of child's difficult temperament (high activity, negative emotionality, and low cooperativeness) were obtained at baseline and three years later. Self-esteem was measured by self-reports six years later, at the ages of 12 and 15. The results indicated considerable gender differences. Among girls nearly all childhood variables individually predicted self-esteem, whereas among boys the associations were less evident. Additionally, perceived difficult temperament at baseline predicted hostile child-rearing attitudes at first follow-up, which further predicted low self-esteem among girls only.     

Positive impression management and its influence on the Revised NEO Personality Inventory: a comparison of analog and differential prevalence group designs

Participants (n = 22) completed the Revised NEO Personality Inventory (NEO PI-R) as part of an authentic job application. Protocols produced by this group were compared with "analog" participants (n = 23) who completed the NEO PI-R under standard instructions and again under instructions designed to mimic the test-taking scenario of the job applicants (the "fake-good" condition). Participants completing the NEO PI-R under fake-good instructions and the job applicants scored lower on the Neuroticism and higher on the Extraversion scales than did the participants responding under standard instructions. Analog participants in the fake-good condition scored higher on the Extraversion and lower on the Agreeableness scales than did the job applicants. These results suggest that outcomes from analog designs are generalizable to real-world samples where response dissimulation is probable.     

Prosocial development in early adulthood: a longitudinal study

Consistency of measures of a prosocial personality and prosocial moral judgment over time, and the interrelations among them, were examined. Participants and friends' reports of prosocial characteristics were obtained at ages 21-22, 23-24, and 25-26 years. In addition, participants' prosocial judgment was assessed with interviews and with an objective measure of prosocial moral reasoning at several ages. Reports of prosocial behavior and empathy-related responding in childhood and observations of prosocial behavior in preschool also were obtained. There was interindividual consistency in prosocial dispositions, and prosocial dispositions in adulthood related to empathy/sympathy and prosocial behavior at much younger ages. Interview and objective measures of moral reasoning were substantially interrelated in late adolescence/early adulthood and correlated with participants' and friends' reports of a prosocial disposition.     

The stability of self-concept during adolescence and early adulthood: a six-year follow-up study

The stability and gender differences of self-concept during adolescence and early adulthood were studied in 894 randomly selected Finnish subjects using the shortened version of the Coopersmith (1967) Self-Esteem Inventory. There were no differences between the men and women in the total score for self-concept. In early adulthood, men scored higher than women on general self-esteem, and women scored higher on the home-parents factor in each developmental period from pre-adolescence to adulthood. The stability of self-concept, as well as its different components, was rather high. General self-esteem showed the highest predictive value for the total score 6 years later.     

Incremental validity of spouse ratings versus self-reports of personality as predictors of marital quality and behavior during marital conflict

The personality traits of neuroticism and agreeableness are consistently related to marital quality, influencing the individual's own (i.e., actor effect) and the spouse's marital quality (i.e., partner effect). However, this research has almost exclusively relied on self-reports of personality, despite the fact that spouse ratings have been found to have incremental validity over self-reports for a variety of other important outcomes. In a study of 300 middle-aged and older married couples, we examined the incremental validity of spouse ratings of neuroticism and agreeableness in predicting concurrent levels of self-reported marital quality, observations of behavior during a marital disagreement task, and depressive symptoms. Neuroticism and agreeableness had expected actor and partner effects on each of these outcomes. Spouse ratings of these traits demonstrated incremental validity in estimates of actor and partner effects on marital quality, marital behavior, and depressive symptoms. Results suggest that spouse ratings of personality may be important additions to the typical reliance on self-reports for research and clinical assessment in marriage.     

The validity and utility of the positive presentation management and negative presentation management scales for the Revised NEO Personality Inventory

Schinka, Kinder, and Kremer developed "validity" scales for the Revised NEO Personality Inventory (NEO PI-R; Costa & McCrae) to detect underreporting-the Positive Presentation Management (PPM) Scale and overreporting-the Negative Presentation Management (NPM) Scale. In this investigation, the clinical utility of these scales was examined using the established validity scales from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al.) as the referent. The sample was composed of 370 psychiatric patients who completed the NEO PI-R and the MMPI-2 as part of a routine evaluation. Results indicated that response distortion compromised the utility of the NEO PI-R domain scales. Moreover, the PPM and NPM scales and an NPM-PPM index significantly differentiated invalid under-and overreporting groups from a valid responding group. The PPM and NPM-PPM index were adequate in classifying under- and overreporters, respectively.     

Relationship between self-esteem and depressive mood in old age: Results from a six-year longitudinal study

The reciprocal nature of the relationship between depression and personality traits (e.g., self-esteem, neuroticism) is still elusive (e.g., vulnerability and scar models). The aim of this study was to examine the longitudinal reciprocal effects between self-esteem and depressive mood in older adults. 757 participants aged 64–97 years assessed 4 times over a six-year period. Cross-lagged models were estimated using SEM. Our findings showed a relative stability over a six-year period of both self-esteem and depressive mood. There were no cross-lagged reciprocal effects between self-esteem and depressive mood over time, thereby rejecting both vulnerability and scar models. It means that self-esteem and depressive mood do not predate each other in old age. These results suggest a developmental phenomenon in which self-esteem and depressive mood follow two parallel and stable developmental trajectories through old age.     

On the usefulness of measures of normal personality for clinical assessment: evidence of the incremental validity of the Revised NEO Personality Inventory

As a means of examining the incremental validity of a normal personality measure in the prediction of selected Axis I and II diagnoses, 1,342 inpatient substance abusers completed the Revised NEO Personality Inventory (NEO-PI-R) and the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) and were assessed with structured clinical interviews to determine diagnostic status. Results demonstrated that scores from the NEO-PI-R (a) were substantially related to the majority of diagnoses, accounting for between 8% and 26% of the variance in the diagnostic criteria; (b) explained an additional 3% to 8% of the variability beyond 28 selected MMPI-2 scale scores; (c) increased diagnostic classification an additional 7% to 23% beyond MMPI-2 scale scores; and (d) were significantly more useful when examined at the facet trait level than at the domain trait level. Implications for incorporating measures of normal personality into clinical assessment batteries are discussed.     

Consensual validity parameters of the Zuckerman-Kuhlman personality questionnaire: evidence from self-reports and spouse reports

One way of validating questionnaire responses is correlating them with ratings made by external assessors who know the ratee well: This is known as consensual validity. In this study, we assessed the consensual validity of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ; Zuckerman, 2002; Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993). A multitrait-multimethod matrix of self-reported and spouse reported personality ratings was used to establish convergent and discriminant validity by means of Campbell and Fiske's (1959) evaluative criteria. Self-reports of 86 men and 85 women were correlated with their spouses' reports. Intraclass correlations ranged from .47 to .63 for the 5 dimensions, providing strong evidence of convergent and discriminant validity. The results obtained favor the use of the ZKPQ as a valid self-report measure of personality traits.     

Continuity and change in the life story: a longitudinal study of autobiographical memories in emerging adulthood

If a person's internalized and evolving life story (narrative identity) is to be considered an integral feature of personality itself, then aspects of that story should manifest some continuity over time while also providing evidence regarding important personality change. Accordingly, college freshmen and seniors provided detailed written accounts of 10 key scenes in their life stories, and they repeated the same procedure 3 months and then 3 years later. The accounts were content analyzed for reliable narrative indices employed in previous studies of life stories: emotional tone, motivational themes (agency, communion, personal growth), and narrative complexity. The results showed substantial continuity over time for narrative complexity and positive (vs. negative) emotional tone and moderate but still significant continuity for themes of agency and growth. In addition, emerging adults (1) constructed more emotionally positive stories and showed (2) greater levels of emotional nuance and self-differentiation and (3) greater understanding of their own personal development in the 4th year of the study compared to the 1st year. The study is the first to demonstrate both temporal continuity and developmental change in narrative identity over time in a broad sampling of personally meaningful life-story scenes.     

Readability of Three Adult Personality Tests: Basic Personality Inventory,Jackson Personality Inventory,and Personality Research Form-E

Three personality tests, the Basic Personality Inventory (BPI), the Jackson Personality Inventory (JPI), and the Personality Research Form-E (PRF-E) were evaluated for readability using a number of indices. Sentence length, word length, sentence type, and four readability formulas indicated that the readability of the BPI, JPI, and PRF-E would not impede the administration or interpretation of these tests in broad segments of the population.     

Determinants of ethnic identity development in adulthood: A longitudinal study

Ethnic identity is defined in terms of the interaction between exploration of and commitment to a given cultural background. The present study investigated the effect of individual background, role transitions, and the social environment on the development of ethnic identity in a sample of German adults aged 21–73 years (N = 2,940). Additionally, identity transitions and the moderating effect of disequilibrating life events on identity over time were examined (N = 827). Overall, results are consistent with findings for other identity domains: Respondents could be assigned to one of four identity stages, ranging from unexamined to achieved identity. Particularly, the individual background and the extent of community involvement affected ethnic identity formation in adulthood. Longitudinal analyses revealed that only one-third of respondents had remained in the same identity stage; most individuals had transitioned forward or backward. Changes in ethnic identity were not moderated by disequilibrating life events.     

Length of Personality Inventory and the Evaluation of a Generalized Personality Interpretation

Subjects were given the same generalized personality interpretation based on personality inventories differing in length. The short inventory was seen as more efficient than the two longer forms. While no significant differences were noted between forms in terms of accuracy and depth of the interpretation, in percentage terms the short form was more favorably evaluated.
