Big Five personality development in adolescence and adulthood

How HEXACO personality traits are involved in school performance of middle school adolescents (10-14 years)

This paper aimed at investigating the relationship between HEXACO personality traits and academic performance in two samples of Italian 10-14 years old middle-school adolescents (N = 714 and N = 1093) using Multilevel Mixed Models. The main results show that: 1) Conscientiousness and Openness to Experience were the most important predictors of school performance, followed by Honesty-Humility; 2) a modest effect was present also for eXtraversion and Emotionality; 3) these influences occurred net of the influence of gender and class and could be generalized to male and female adolescents across 6th, 7th and 8th grade; 5) Perfectionism, Diligence and Prudence within Conscientiousness, Inquisitiveness within Openness, and Sincerity within Honesty-Humility were the facets more correlated with school performance; 6) results were replicated in two studies. Results are discussed and conclusions are drawn.

Exploring the relationship between personality traits and locus of control in early adolescence. Does gender play a role?

The main aim of this study was to analyse associations between the five-factor model personality traits and locus of control of successes and failures based on the theory of social learning and to assess whether gender moderated relationships between these variables in Polish early adolescents. The following instruments were used: the Picture Based Personality Survey for Children and the Locus of Control Questionnaire. A total of 1016 students participated in the study, including 49% boys and 51% girls. Both for girls and boys, the highest correlations were found between conscientiousness and locus of control in success situations. Neuroticism correlated negatively with the two types of locus of control. A moderating effect of gender was observed between openness to experience and locus of control of successes, and it was stronger in girls than in boys.

Adolescent personality development as a longitudinal marker for burnout and happiness in emerging adulthood

This study examined whether individual differences in personality (development) from adolescence to emerging adulthood were associated with burnout and happiness in emerging adulthood. At Time 1 (2009; Mage = 15.7 years), Time 2 (2012), and Time 3 (2015), Belgian participants ( N = 329; 43.1% boys) reported on the personality dimensions of extraversion, agreeableness/benevolence, conscientiousness, emotional stability, and openness/imagination. Burnout (exhaustion, disengagement) and happiness (life satisfaction, overall affect) were measured through self-reports at Time 4 (2018). For each personality dimension, except benevolence, higher levels were associated with fewer burnout symptoms. Initial levels of all personality dimensions were related to more happiness. Shallower decreases in extraversion, emotional stability, and stronger increases in imagination were related to fewer burnout symptoms and more happiness. Results indicate the importance of studying personality development as a determinant of later well-being, above and beyond effects of initial levels. Findings offer new insights into the field of personality, occupational, and positive psychology.

Does intelligence predict development of investment traits from mid to late adolescence? Evidence from a 3-year longitudinal study

INTRODUCTION

Investment theories have claimed reciprocal relations between intelligence and investment traits (i.e., personality traits related to seeking out, and dealing with, cognitive challenges). However, previous research has primarily addressed the effects of investment traits on intellectual development (environmental enrichment hypothesis) and often focused on either childhood or later adulthood. The present study investigated the effects of intelligence on investment traits (environmental success hypothesis) from mid to late adolescence.

METHOD

In a 3-year longitudinal survey (2008-2011) covering four measurement occasions, the predictive effects of both fluid and crystallized intelligence on intraindividual change in both the achievement motive (i.e., hope for success and fear of failure) and need for cognition were examined. Overall, 476 adolescents (t₁ : M_age  = 16.43, SD = 0.55; 51.3% girls) from Germany participated.

RESULTS

Second-order latent growth models indicated that fluid intelligence predicted a steeper growth in hope for success (β = .40), but was unrelated to change in the other investment traits. Crystallized intelligence had no effects on the investment traits under study.

CONCLUSIONS

The results contribute to the research on the bidirectionality of intelligence and investment traits and add to our understanding of personality development from mid to late adolescence. Specifically, they underline the importance of nurturing hope for success especially in individuals with lower intelligence, but also show that support for the environmental success hypothesis seems to be limited to certain investment traits.

Trajectories of temperament from late childhood through adolescence and associations with anxiety and depression in young adulthood

Anxiety and depression are pervasive and pernicious mental health problems for young adults. Developmental trajectories of adolescent temperament (Effortful Control, Negative Emotionality, and Positive Emotionality) may help us predict who will experience anxiety/depression during young adulthood. The present study used longitudinal data from a large, community sample of Mexican-origin youth ( N = 674) to examine how temperament develops across adolescence (age 10–16) and whether the developmental trajectories of temperament are associated with anxiety/depression during young adulthood (ages 19 and 21). Results indicate that Effortful Control, Negatively Emotionality, and the Affiliation facet of Positive Emotionality tend to decrease across adolescence, whereas Surgency tends to increase. Smaller decreases in Effortful Control and greater increases in Positive Emotionality across adolescence were associated with fewer anxiety/depression symptoms during young adulthood, whereas smaller decreases in Negative Emotionality were associated with more anxiety/depression symptoms later on. Thus, temperament development serves as both a protective factor (Effortful Control, Positive Emotionality) and a risk factor (Negative Emotionality) for later anxiety/depression in Mexican-origin youth.

The personality and cognitive traits associated with adolescents' sensitivity to social norms

Little is known about the personality and cognitive traits that shape adolescents' sensitivity to social norms. Further, few studies have harnessed novel empirical tools to elicit sensitivity to social norms among adolescent populations. This paper examines the association between sensitivity to norms and various personality and cognitive traits using an incentivised rule-following task grounded in Game Theory. Cross-sectional data were obtained from 1274 adolescents. Self-administered questionnaires were used to measure personality traits as well as other psychosocial characteristics. Incentivised rule-following experiments gauged sensitivity to social norms. A series of multilevel mixed effects ordered logistic regression models were employed to assess the association between sensitivity to norms and the personality and cognitive traits. The results highlighted statistically significant univariate associations between the personality and cognitive traits and sensitivity to norms. However, in the multivariate adjusted model, the only factor associated with sensitivity to norms was gender. The gender-stratified analyses revealed differences in the personality and cognitive traits associated with sensitivity to norms across genders. For males need to belong was significantly negatively associated with sensitivity to norms in the multivariate model. By comparison, emotional stability was negatively associated with sensitivity to norms for females. This study reinforced the findings from an earlier study and suggested female adolescents had higher levels of sensitivity to norms. The results indicated no consistent pattern between sensitivity to norms and the personality and cognitive traits. Our findings provide a basis for further empirical research on a relatively nascent construct, and bring a fresh perspective to the question of norm-following preferences among this age group.

Maturation or disruption? Conscientiousness development in the transition into adolescence

Research to date has shown longitudinal changes in conscientiousness during early and middle adolescence, but most studies have been conducted in Western countries. The present study aimed to examine the pattern of mean-level conscientiousness change at the transition into early adolescence among a Chinese sample using curve of factors (CUFFS) models. Four waves of data from 661 Chinese children aged 8 years old at baseline in the China Family Panel Studies were used. Parents were asked to rate their children’s level of conscientiousness every 2 years. On average, mean-level conscientiousness showed a decelerating increase. Girls had higher average conscientiousness levels than boys, but they did not differ in change patterns. The inconsistency between the current study and previous research indicates that conscientiousness development may depend, in part, on cultural factors.

Intra-Individual Variability in Creativity

Abstract. Individual differences perspectives have dominated the scientific study of creativity since the 1950’s. These perspectives, however, mainly emphasize group-level variations or inter-individual differences, with limited interest in individual-level variations. Yet, (1) group-level findings are often used to make inferences at the person-level, which might not apply consistently across individuals, and (2) a focus on intra-individual variations could supplement knowledge based on inter-individual differences and accurately inform creativity as a dynamic and multifaceted psychological construct. Indeed, when observed at the individual level, creativity can vary from moment to moment, task to task, and even item to item, which is not well reflected in the current understanding of creativity. After introducing the historical context for the study of individual differences in creativity, this article presents and illustrates three fundamental and distinct aspects of intra-individual variability as they apply to creativity, namely (in)consistency (or processing fluctuation), dispersion, and intraindividual change. While doing so, recent developments in apparatus and methods to assess creativity as a more dynamic phenomenon are presented. The article concludes by discussing the promise of accounting for intra-individual variability in creative performance and potential and the new knowledge it may elicit for both creativity research and practice.

Entrepreneurial tendency across the adult lifespan

This study examines whether age associates with entrepreneurship tendencies across the lifespan, after taking into account aspects of personality that affect entrepreneurship. Participants (N = 963) aged 18–81, including 200 actual entrepreneurs, completed questionnaires about entrepreneurship tendency, personality traits, and attachment orientations. Results show that age is associated with a reduced tendency to engage in entrepreneurial activity. However, this decline is quite limited, it weakens with age, and is absent after age 50. In addition, the negative association of age with entrepreneurial tendency is smaller in participants with above-median entrepreneurship tendency scores relative to those with below-median scores, and it disappears in actual entrepreneurs. Furthermore, most of the traits that have been previously associated with entrepreneurial tendencies, especially Openness to Experience and Extraversion, remain unchanged with age, accounting for the stability of entrepreneurial tendency over time. The results have implications for policy makers who wish to encourage older adults to engage in entrepreneurial activity.

Exploring associations between subjective well-being and personality over a time span of 15-18 months: a cohort study of adolescents in Sweden

Introduction

Subjective well-being (SWB) is a contributing factor for building resilience and a resource for positive outcomes, e.g. study achievement and work performance. Earlier studies have examined associations between and prospective effects of personality traits on SWB, but few addressed the role that SWB plays in formation of personality over time. The purpose of our study was to examine associations and prospective effects of SWB on personality traits and vice versa in a cohort sample of secondary school students in Sweden who completed self-reported measures of SWB and personality traits at baseline (N = 446, 76% females) and at 15–18 month follow-up (N = 283, 71% females).

Methods

SWB was defined and measured by the WHO-5 Well-being Index and the Satisfaction with Life Scale. The Big Five Inventory was used to measure personality traits. Autoregressive models were used to analyse associations and potential prospective effects of SWB on personality traits and vice versa.

Results

Low levels of neuroticism and high levels of extraversion, conscientiousness and agreeableness were associated with high levels of SWB at baseline and follow-up. The association between SWB and neuroticism was notably strong. We found high statistically significant rank order stability across the two time points for all measures of personality traits with stability effects, derived from the autoregressive models, ranging from .199 for extraversion to .440 for neuroticism. Stability for SWB was statistically significant across the two time points and ranged from .182 for well-being to .353 for life satisfaction. SWB had a prospective effect on agreeableness only. None of the personality traits had any significant prospective effects on SWB.

Conclusions

The present findings indicate that although correlated, bidirectional prospective effects between personality traits and SWB could not be confirmed. Neuroticism displayed the strongest negative association with adolescents’ SWB. Schools are an appropriate setting to improve well-being, and allocating resources that reduce neuroticism is crucial, including structural interventions, policies for healthy school settings and teaching emotional regulation techniques.

Mixed Results on the Efficacy of the CharacterMe Smartphone App to Improve Self-Control, Patience, and Emotional Regulation Competencies in Adolescents

Unprecedented levels of access to adolescents' time and attention provide opportunities to convert traditional character and socioemotional competencies interventions into behavioral intervention technologies. However, these new tools must be evaluated rather than assuming previously validated activities will be efficacious when converted to a mobile platform. Thus, we sought to design and provide initial data on the effectiveness of the CharacterMe smartphone app to build self-control and patience, which are built on underlying social-emotional regulation competencies, in a sample of 618 adolescents (M_age = 16.07, Female = 56.6%). We also sought to examine whether framing the app activities as having a transcendent (spiritual connection or moral/prosocial) rather than instrumental purpose would increase engagement and change in self-control, patience, and emotion regulation. Finally, we tested the impact of framing activities as building strengths vs. fixing weaknesses. Results highlight the difficulty of translating psychological interventions to behavioral intervention technologies. Overall, the CharacterMe smartphone app was unsuccessful in increasing self-control, patience, or emotion regulation in adolescents, with analyses showing no significant mean changes over time. Framing conditions and user engagement were largely not significant predictors of change in self-control, patience, and emotion regulation.

Becoming a perfectionistic adolescent: Perceived parental behaviors involved in developmental trajectories of perfectionism

Perfectionism is a pervasive and prevalent personality disposition with high implications for psychological maladjustment. Adolescence represents a particularly relevant period for the development of perfectionism, and perceived parental behaviors have been shown to play an important part. Yet, so far only few longitudinal studies have investigated the role of risk and protective parental behaviors in the development of perfectionism in adolescents. Examining a sample of 744 adolescents ( Mage = 15.2 years), the present study investigated developmental trajectories of self-oriented, socially prescribed, and other-oriented perfectionism over four waves spaced five to six months apart. Results of growth mixture modeling showed that self-oriented perfectionism followed three developmental trajectories (low and decreasing; medium and decreasing; high and stable) as did socially prescribed perfectionism (low and stable; medium and increasing; high and stable). Other-oriented perfectionism showed four developmental trajectories (low and decreasing; low and stable; high and stable; high and increasing). Significant differences were observed between groups regarding all investigated perceived parental behaviors (psychological control, behavioral control, responsiveness, and autonomy support). Similarities and differences between the development of each form of perfectionism and the role of each parental behavior as well as implications of these findings for the understanding of the development of perfectionism in adolescence are discussed.

On the Rocky Road to Independence: Big Five Personality Traits and Locus of Control in Polish Primary School Students during Transition into Early Adolescence

This article reports the results of a survey of 455 Polish primary school sixth-graders experiencing changes in the education system. The goal of the study was to identify the relationships between the Big Five personality traits, measured with the picture-based personality survey for children (PBPS-C) and locus of control, determined using the locus of control questionnaire (LOCQ). The results lead to the conclusion that primary school students do not have an established locus of control of either success or failure. There are also no significant differences between boys and girls in the way they interpret the causes of situations and events that happen to them. Boys, compared to girls, scored significantly higher on traits related to seeking and enjoying the company of others. On the other hand, girls exhibited significantly higher levels of traits responsible for increased anxiety than boys. The personality traits that correlated the strongest with locus of control were Conscientiousness, Openness to Experience, and Agreeableness. A regression model showed that locus of control of success was significantly affected by two traits: Extraversion and Conscientiousness. Locus of control of failure was significantly predicted by Extraversion, Openness to Experience, Agreeableness (positively), and Neuroticism (negatively). Regression model with gender as a moderator of relationships between personality traits and locus of control turned out to be insignificant.

Age and gender differences in personality traits from early childhood through adolescence

OBJECTIVE

Most research on personality development has employed self-report questionnaires and concerned individuals older than 10 years. This is the first study to examine mean-level age differences in personality traits from early childhood to late adolescence in the non-Western cultural context.

METHOD

Personality was measured in two community samples of parent reports of 2-18-year-old children (N = 4,330) and self-reports of 10-19-year-old adolescents (N = 4,663) from Russia by the Inventory of Child Individual Differences-Short version (ICID-S) at the three levels of the hierarchy, the two higher order traits, the Big Five, and lower order traits.

RESULTS

Across childhood, the Agreeableness, Conscientiousness, and Neuroticism traits increased, and the Extraversion and Openness traits decreased. In adolescence, parent-reported Conscientiousness traits increased and Neuroticism traits decreased, whereas youth-rated Alpha and Agreeableness decreased in middle adolescence. There were small gender differences in trait levels and age trends. Parents and youths did not agree on gender differences in age trends for Neuroticism and Extraversion.

CONCLUSION

The findings support personality maturation from early childhood to late adolescence, with the exception of increasing Neuroticism across childhood, and provide some evidence for the disruption in personality maturation in adolescence. Parents and adolescents may have different perspectives on personality development.

Comparações entre Meninos e Meninas no Zulliger - Sistema Compreensivo

Resumo O objetivo deste estudo foi verificar se existe diferença no desempenho entre meninos e meninas no teste de Zulliger, pelo Sistema Compreensivo ZSC. A amostra constituiu-se de 623 crianças com idades entre 6 a 14 anos, provenientes da região Sudeste do Brasil, divididas em quatro faixas etárias, a saber, seis a sete anos, oito a nove, dez a onze e doze a quatorze anos. As médias foram comparadas por meio do teste t. Os resultados indicaram que algumas diferenças foram significativas, embora o número de variáveis tenha sido reduzido consideravelmente, quando comparado com a literatura. Os achados são discutidos junto a estudos com técnicas projetivas e outros de personalidade. Conclui-se que, embora muitas variáveis sejam corroboradas na literatura, são necessários mais estudos com amostras mais homogêneas, por exemplo, controlando nível cognitivo e variáveis sociodemográficas.

Parental styles, gender and the development of hope and self‐esteem

We examined the developmental trajectory of trait hope and self‐esteem over 4 years and the impact of gender and perceived parental styles on these trajectories. Participants were 884 high school students. There was a general decline in hope and self‐esteem over time, with females declining more rapidly than males. Girls had higher hope than boys in Grade 7, but lower hope by Grade 10. Perceived parental authoritativeness at Time 1 was related to high hope across the 4 years, whilst perceived parental authoritarianism was related to low self‐esteem. We discuss the importance of perceived parental styles for adolescent well being, as well as possible explanations for changes in hope and self‐esteem. Copyright © 2008 John Wiley & Sons, Ltd.

Emotional Stability and Affective Self–regulatory Efficacy Beliefs: Proofs of Integration between Trait Theory and Social Cognitive Theory

The present study aimed to investigate the development and interplay of emotional stability and affective self–regulatory efficacy beliefs through adolescence to young adulthood. A latent growth curve approach was used to investigate level and stability of emotional stability and self–efficacy in managing negative emotions and in expressing positive emotions. We found that initial levels of emotional stability and self–efficacy beliefs are highly correlated. In accordance with the posited hypothesis, the growth rate of perceived self–efficacy in managing negative emotions predicted the growth rate of emotional stability, whereas the opposite path was not significant. The growth rates of perceived self–efficacy in expressing positive emotions and emotional stability were not related to each other. Taken together, these findings point to self–efficacy beliefs as instrumental to the change of traits. Practical implications of results are discussed, highlighting the role of social cognitive theory in supplying the proper strategies to design effective interventions to enable people to make the best use of their potentials.

Stressful Events and Temperament Change during Early and Middle Adolescence: The TRAILS Study

This project investigates how stressful events are related to deviations from normative temperament development during adolescence. Temperament traits were assessed at ages 11 and 16 years. Life–event data was captured using an interview (total n = 1197). Normative changes were found in all traits. A linear trend was found between the experience of stressful events and temperament development. Adolescents exposed to stressful events showed smaller decreases in fear and shyness, stronger decreases in effortful control and affiliation and smaller increases in high intensity pleasure. Exposure to stressful events was related to increases in frustration instead of decreases. Our results show that whereas normative development is mostly in the direction of maturation, adolescents who experienced stressful events showed less maturation of their temperament.

Self–other agreement in personality development in romantic couples

A large body of evidence indicates that personality traits show high rank-order stability and substantial mean-level changes across the lifespan. However, the majority of longitudinal research on personality development has relied on repeated assessments of self-reports, providing a narrow empirical base from which to draw conclusions and develop theory. Here, we (1) tested whether self- and informant-reports provided by couples show similar patterns of rank-order stability and mean-level change and (2) assessed self–other agreement in personality development. We charted the Big Five personality trajectories of 255 couples ( N = 510; M age = 27.01 years) who provided both self- and partner-reports at four assessments across 1.5 years. Results indicated similar rank-order stabilities in self- and partner-report data. Latent growth curve models indicated no significant differences between self- and partner-reported personality trajectories, with exceptions to extraversion and agreeableness. We further found strong cross-sectional agreement across all Big Five traits and assessment waves as well as moderate self–other agreement in personality change in emotional stability and agreeableness. These findings highlight the relevance of multi-method assessments in personality development, while providing information about personality stability and change. Discussion focuses on the theoretical implications and future directions for multi-method assessments in longitudinal personality research.

Personality determinants of subjective executive function in older adults

Objectives: Problems in subjective executive function, the perceived cognitive control of mental processes for goal-directed behavior, may indicate cognitive impairment in older adulthood. Although, previous studies highlight the importance of personality on objective cognitive performance, no studies clarify their role with subjective executive function. To inform methods of early identification of cognitive impairment, this study explored how temperament and personality traits account for problems in subjective executive function.Method: The current project examined the associations between temperament and personality on subjective executive function across two samples of community-dwelling older adults (65+ years, n₁ = 25, n₂ = 50). Both studies measured subjective executive function (Behavioral Rating Inventory of Executive Function-Adult) and separately administered scales on temperament (Adult Temperament Questionnaire) and personality (Big Five Inventory).Results: Concerning temperament, older adults higher in negative affect endorsed greater difficulty in subjective executive function. Regarding personality traits, older adults with higher neuroticism and lower conscientiousness reported higher difficulty in subjective executive function.Conclusion: Findings enhance our understanding of subtle cognitive changes and may aid in early detection. In particular, distressful inclinations were associated with more reported problems in executive function whereas problem-solving tendencies were inversely related. Future work should examine if enhanced negativity coupled with analytical disengagement predicts problems in subjective executive function over time.

Personality Development from Age 12 to 25 and its Links with Life Transitions

During adolescence and young adulthood, individuals show personality changes and experience various life transitions. Whereas personality might affect the timing of life transitions, life transitions might also induce personality maturation. We examined Big Five personality maturation from age 12 to 25 using a 9–year longitudinal study of Dutch youths from two cohorts ( n 1 = 683, MageT1 = 12.70; n 2 = 268, Mage T1 = 16.87). We linked personality maturation to the incidence and timing of four transitions: first romantic relationship, leaving the parental home, first job, and first cohabitation or marriage. Results indicated increases in mean levels, rank–order stabilities and profile stability of personality between age 12 and 25, which were largely replicated across the cohorts. Very few associations between personality and life transitions existed. However, higher mean–level Extraversion predicted leaving the parental home and starting the first romantic relationship, an earlier age when starting the first job, and an earlier average timing of transitions. Regarding social investment effects, we only found that those who never experienced a romantic relationship at age 25 decreased, while those who did increased in profile stability over time. These results suggest that personality consistently matures during adolescence and young adulthood and that higher Extraversion predict greater readiness for new steps towards adulthood.

Big Five personality traits among Polish students facing the transformations of the education system

Background

The aim of the present study was to analyze personality traits in the Big Five Model among Polish students in early adolescence, who were on the verge of introduction of a new reform in the Polish education system. The article presents a summary of the results of the first of the planned three stages of the longitudinal study.

Participants and procedure

The participants of the study were 910 people at the sixth grade of primary schools, aged from 11 to 13 (M = 12.40, SD = 0.58), and at the first grade of junior high schools, aged from 12 to 14 (M = 13.40, SD = 0.53) in the school year 2016/2017. The analysis of personality traits was carried out using the Picture Based Personality Survey for Children (PBPS-C v1).

Results

The results showed that young people from primary schools are more conscientious and open to experience than their older schoolmates. Girls from primary schools are more conscientious and open to new experience than their older peers; and boys from primary schools are more conscientious than their older schoolmates. Gender and level of education turned out to be sig-nificant predictors of some personality traits. Extraversion is associated with boys while neuroticism and agreeableness are as-sociated with girls. Level of education is associated with openness to experience and conscientiousness.

Conclusions

The results are discussed in the context of possible practical rearing influence aimed at supporting young people’s development in the context of educational changes that they are about to face.

Sequences of maladaptation: Preadolescent self-regulation, adolescent negative social interactions, and young adult psychopathology

This study aims to test whether adolescent negative social interactions mediate the relation between early adolescent self-regulatory capacities and young adult psychopathology, using a fully prospective mediation model. Data were derived from the Tracking Adolescents' Individual Lives Survey, a large population cohort of Dutch adolescents (n = 962). At age 11, three indicators of self-regulation were assessed: low frustration, high effortful control, and high response inhibition. Negative social interactions between ages 11 and 22 were captured twice using the Event History Calendar. Psychopathology (i.e., internalizing and externalizing problems) was assessed at ages 11 and 22. Findings indicate that adolescents' frustration and effortful control but not response inhibition assessed at age 11 are related to both internalizing and externalizing problems at age 22, after controlling for psychopathology at age 11, sex, and socioeconomic status. These associations were partly (about 22%) mediated by the negative social interactions adolescents experienced. Effect sizes were all modest. This study shows that self-regulation is related to subsequent psychopathology in part through its effect on negative social interactions, providing evidence for sequences of self-regulatory capacities, life experiences, and developmental outcomes.

Development and Initial Validation of the Five-Factor Model Adolescent Personality Questionnaire (FFM-APQ)

This research reports on the 4-phase development of the 25-item Five-Factor Model Adolescent Personality Questionnaire (FFM-APQ). The purpose was to develop and determine initial evidence for validity of a brief adolescent personality inventory using a vocabulary that could be understood by adolescents up to 18 years old. Phase 1 (N = 48) consisted of item generation and expert (N = 5) review of items; Phase 2 (N = 179) involved item analyses; in Phase 3 (N = 496) exploratory factor analysis assessed the underlying structure; in Phase 4 (N = 405) confirmatory factor analyses resulted in a 25-item inventory with 5 subscales.

Self-Concept in Adolescents-Relationship between Sport Participation, Motor Performance and Personality Traits

The relationship between sport participation, personality development, self-concept and self-esteem has been discussed repeatedly. In this research, a standardized written survey together with tests on motor performance were carried out with 1399 students (707 male; 692 female) in school years 7 (12.9 ± 0.6 years) and 10 (15.8 ± 0.6 years) to measure the extent of a relationship between physical self-concept (self-developed short scale) and sporting activity, measured motor performance (German motor performance test DMT (Deutscher Motorik-Test) 6–18) and report mark in physical education. Relationships were also analyzed between physical self-concept and general personality traits (neuroticism, extraversion, openness to experiences, compatibility, and conscientiousness, measured with NEO Five Factor Inventory (NEO-FFI)). The assessment of own physical attractiveness and own athleticism differs by sex (F(1, 962) = 35.21; p < 0.001), whereby girls assess themselves more critically. Weak significant relationships are displayed between motor performance and the assessment of own physical attractiveness (r(395) = 0.31; p < 0.01). Motor performance is given a higher predictive value with regard to a subject’s own self-concept, (physical attractiveness β = 0.37; t(249) = 5.24; p < 0.001; athleticism β = 0.40; t(248) = 6.81; p < 0.001) than the mark achieved in physical education (physical attractiveness β = −0.01; n.s.; athleticism β = −0.30; t(248) = 5.10; p < 0.001). Relationships were found overall between personality traits and physical self-concept. The influence of the ‘neuroticism’ trait is particularly strong (physical attractiveness β = −0.44; t(947) = −13.58; p < 0.001; athleticism β = −0.27; t(948) = −7.84; p < 0.001). The more pronounced this trait, the lower the assessment of own physical attractiveness and own athleticism.

Neighbourhood Poverty, Work Commitment and Unemployment in Early Adulthood: A Longitudinal Study into the Moderating Effect of Personality

We studied how personality moderates the effect of neighbourhood disadvantage on work commitment and unemployment in early adulthood. Using a personality typology of resilients, overcontrollers, and undercontrollers, we hypothesised that the association between neighbourhood poverty and both work commitment and unemployment would be stronger for overcontrollers and undercontrollers than for resilients. We used longitudinal data (N = 249) to test whether the length of exposure to neighbourhood poverty between age 16 and 21 predicts work commitment and unemployment at age 25. In line with our hypothesis, the findings showed that longer exposure was related to weaker work commitment among undercontrollers and overcontrollers and to higher unemployment among undercontrollers. Resilients’ work commitment and unemployment were not predicted by neighbourhood poverty.

On Correlated Change in Personality

Abstract. Correlated change in personality is essential to understanding change and development. It refers to the question of whether and to what degree changes in personality are interrelated over time within and between individuals. Compared to the longstanding literature on personality development, relatively less research has focused on correlated change in personality. The main goal of this paper is thus to discuss the potential of this concept for the field of personality development. First, we define correlated change and propose a categorization framework with multiple dimensions. Second, we discuss several theoretical concepts of correlated change that help understand the patterns, causes, and mechanisms underlying correlated change in personality. Third, we briefly describe several statistical approaches to modeling correlated change. Fourth, we summarize previous research on correlated change in personality. We focus our research on (a) correlated change within the Big Five personality traits, and (b) between the Big Five personality traits and three domains of life. Finally, we conclude by discussing challenges and future directions of the concept for the field of personality development.

Личност, кариерни интереси и стратегии за професионална реализация в годините на възникващата зрелост (18-29 г)

Една от психосоциалните задачи на развитието през годините на възникващата зрелост (18-29 г.) е свързана с избора на кариера. Настоящата статия се опитва да изясни професионалната идентичност на младите хора в България, посредством техните кариерни интереси, стратегии за трудова реализация и личностни особености. Извадката се състои от 257 изследвани лица на възраст 18-29 г. Използвана е скалата на Орегон за измерване на професионалните интереси - ORVIS (Pozzebon, Visser, Ashton, Lee, & Goldberg, 2010), въпросник за изучаване на алтернативи и стратегии за трудова реализация (Bozhinova, 2003) и въпросник за измерване на пет факторната структура на личността - Big Five model (Costa & McCrae, 1992). Резултатите от изследването показаха, че в годините на възникваща зрелост се открояват професионалните интереси Креативност, Алтруизъм и Лидерство в комбинация със средноактивна стратегия за реализация и ориентиране на пазара на труда. Личностните фактори, които доминират, са Съзнателност, Отвореност към опита и Доброжелателност. Петте фактора на личността си взаимодействат слабо със седем от осемте професионални интереса при младежите.

Whose "Storm and Stress" Is It? Parent and Child Reports of Personality Development in the Transition to Early Adolescence

The present study investigated Big Five personality trait development in the transition to early adolescence (from the fifth to eighth grade). Personality traits were assessed in 2,761 (47% female) students over a 3-year period of time. Youths' self-reports and parent ratings were used to test for cross-informant agreement. Acquiescent responding and measurement invariance were established with latent variable modeling. Growth curve models revealed three main findings: (a) Normative mean-level changes occurred for youths' self-report data and parent ratings with modest effects in both cases. (b) Agreeableness and Openness decreased for self-reports and parent ratings, whereas data source differences were found for Conscientiousness (decreased for self-reports and remained stable for parent ratings), Extraversion (increased for self-reports and decreased for parent ratings), and Neuroticism (remained stable for self-reports and decreased for parent ratings). (c) Girls showed a more mature personality overall (self-reports and parent ratings revealed higher levels of Agreeableness, Conscientiousness, and Openness) and became more extraverted in the middle of adolescence (self-reports). Personality changes modestly during early adolescence whereby change does not occur in the direction of maturation, and substantial differences exist between parent ratings and self-reports.

"Peaks, Slumps, and Bumps": Individual Differences in the Development of Creativity in Children and Adolescents

This article reviews developmental studies of creativity in children and adolescents with a focus on "peaks" and "slumps" that have often been described in the literature. The irregularity of the development of creativity is interpreted in light of conceptual and measurement issues and with regard to the interaction between individual-level resources, task-specific demands, and environmental influences, resulting in apparent individual differences in the development of creativity. The need for longitudinal designs, multidimensional and multi-domain assessment of creative potential limiting the contribution of task-specific factors is outlined and discussed as an important direction for developmental research on creativity.

Neuroticism and extraversion in relation to physiological stress reactivity during adolescence

The current study examined mean level and change in extraversion and neuroticism across adolescence in relation to physiological stress reactivity to social evaluation. Adolescents (n=327) from the Dutch general population reported on personality measures at five annual assessments. At age 17 years, adolescents participated in a psychosocial stress procedure characterized by social evaluation during which cortisol, heart rate, pre-ejection period (PEP) and heart rate variability were assessed. Dual latent growth curve models were fitted in which the intercepts (mean level) and slopes (change) of personality across adolescence predicted the intercepts (baseline) and slopes (reactivity) of the physiological stress measures. Most comparisons revealed no relation between personality and stress reactivity. Adolescents with higher mean level scores on extraversion did show lower cortisol reactivity. Adolescents with higher mean level neuroticism scores showed higher PEP reactivity. Our findings lend partial support for a relation between personality and physiological stress reactivity.

The relationship between temperament and character and psychotic-like experiences in healthy children and adolescents

BACKGROUND

Prior work by our group identified personality profiles associated with psychotic-like experiences (PLE's) in healthy adults that were strikingly similar to those found in schizophrenia patients, with the exception of two key differences. Specifically, higher levels of PLE's were linked to higher persistence and cooperativeness, suggesting that these characteristics might represent personality-based resilience factors. Notably, age and personality were significantly correlated in these data, raising questions about whether healthy children and adolescents would show similar results. To date, no study has examined personality profiles associated with both positive and negative PLE's in healthy children and adolescents using Cloninger's Temperament and Character Inventory (TCI). Thus, this study examined the relationship between TCI dimensions and PLE's in healthy children and adolescents.

METHOD

The TCI and the Community Assessment of Psychic Experiences (CAPE) were administered to 123 healthy children and adolescents aged 8-18. Multiple regression models were used to examine personality dimensions associated with overall severity of PLE's as well as severity of positive and negative PLE's separately.

RESULTS

Positive, negative, and overall PLE severity were all associated with a personality pattern of higher harm avoidance and lower self-directedness. Negative PLE severity was also associated with lower persistence.

CONCLUSIONS

Personality correlates of PLE's in healthy children and adolescents were largely consistent with our past work on PLE's in healthy adults. However, our previously identified resilience factors were notably absent in this sample. These findings may suggest that these personality characteristics have not yet crystallized or emerged to aid in coping with PLE's.

Testing the effectiveness of a mentoring intervention to improve social participation of adolescents with visual impairments: study protocol for a randomized controlled trial

BACKGROUND

Social participation is challenging for people with visual impairments. As a result, on average, social networks are smaller, romantic relationships formed later, educational achievements lower, and career prospects limited. Adolescents on their way towards achieving these goals may benefit from the knowledge and experience of adults who have overcome similar difficulties. Therefore, a mentoring intervention, called Mentor Support, will be set up and studied in which adolescents with visual impairments are matched with successfully social participating adults with and without visual impairments. The main objective of this study is to evaluate the effectiveness of Mentor Support. Secondary aims are to distinguish the importance of the disability-specific experience of mentors, predictors of success, and mediating factors.

METHODS/DESIGN

The effect of Mentor Support will be tested in a randomized clinical trial, using pre-test one week before starting, post-test after 12 months, and follow-up after 18 months. Participants will be referred to one of the experimental groups or the control group, and this randomization will be stratified according to country region. Three groups are included in the trial: 40 participants will receive Mentor Support by mentors with a visual impairment in combination with care-as-usual, 40 participants will receive Mentor Support by mentors without visual impairments in combination with care-as-usual, and 40 participants will receive care-as-usual only. Mentor Support consists of 12 face-to-face meetings of the mentee with a mentor with an overall time period of one year. On a weekly basis, dyads have contact via email, the Internet, or telephone. The primary outcome measure is improved social participation within three domains (work/school, leisure activities, and social relationships). Mediator variables are psychosocial functioning and self-determination. Predictors such as demographics and personality are also investigated in order to distinguish the pathways to successful social participation. Intention-to-treat and completer analyses will be conducted.

DISCUSSION

The primary outcomes of this trial regard increased social participation. The study may yield insights to further improve effects of support programs to adolescents with visual impairments.

Personality trait change across late childhood to young adulthood: Evidence for nonlinearity and sex differences in change

We explored patterns of self-reported personality trait change across late childhood through young adulthood in a sample assessed up to 4 times on the lower-order facets of Positive Emotionality (PEM), Negative Emotionality (NEM), and Constraint (CON). Multilevel modeling analyses were used to describe both group- and individual-level change trajectories across this time span. There was evidence for nonlinear age-related change in most traits, and substantial individual differences in change for all traits. Gender differences were detected in the change trajectories for several facets of NEM and CON. Findings add to the literature on personality development by demonstrating robust nonlinear change in several traits across late childhood to young adulthood, as well as deviations from normative patterns of maturation at the earliest ages.

Genetic and Environmental Contributions to Personality Trait Stability and Change Across Adolescence: Results From a Japanese Twin Sample

We examined developmental trends and sources of stability and change in adolescent personality by using twin data collected from 1981 to 2010 (273 monozygotic (MZ) and 48 dizygotic (DZ) twin pairs) from a secondary school affiliated with the University of Tokyo. Phenotypic analyses showed high rank-order stability and substantial mean-level increases in neuroticism and declines in extraversion over the adolescent years. Longitudinal bivariate genetic analyses revealed that the best-fitting model for adolescent personality includes additive genetic and non-shared environmental influences. Heritability estimates ranged approximately from 0.30 to 0.60. Additionally, three-year stability in adolescent personality was influenced mainly by genetic factors, and there were both genetic and environmental innovations in mid-adolescence. Our findings suggest that both genetic and environmental effects have significant roles in the etiology of personality development across adolescence.
