Life Events and Personality Trait Change

The prospective power of personality for childbearing: a longitudinal study based on data from Germany

The link between personality and fertility is relatively underexplored. Moreover, there are only a few studies focusing on the prospective association between personality and childbearing. However, none of these studies considered the Five-Factor Model (FFM), which is the most widely accepted measurement of personality. The present study fills this gap by examining the prospective association between the FFM and the hazard ratio of the first and the second childbirth in Germany. Analyses are based on recent data (2005–2017) from the Socio-economic Panel Study. Cox proportional hazard models are applied. Findings demonstrate that personality traits are associated with fertility. Extraversion is positively linked with the first childbirth, but is negatively associated with the second childbirth. These findings are mainly driven by males. Agreeableness is positively linked with the first childbirth across the total sample. Again, this correlation is mainly based on the findings for men, among whom a positive association between agreeableness and the second childbirth is also found. Among women, personality does not seem to be linked with the first childbirth. However, the risk of having a second child is found to be negatively associated with conscientiousness. My study adds to the current understanding of the personality–fertility association by exploring the impact of personality trait scores from the FFM on subsequent fertility behavior. However, further research is needed on the association between personality and childbearing; on the mechanisms through which personality affects fertility; and on how these links differ across cultures, among higher parities, and for births after re-partnering.

Examining individual differences in personality trait changes after negative life events

Personality traits can change throughout the entire life span, but people differ in their personality trait changes. To better understand individual differences in personality changes, we examined personal (personality functioning), environmental (environmental changes), and event-related moderators (e.g., perceived event characteristics) of personality trait changes. Therefore, we used a sample of 1069 participants who experienced a negative life event in the last 5 weeks and assessed their personality traits at five measurement occasions over 6 months. Employing preregistered multilevel lasso estimation, we did not find any significant effects. While exploratory analyses generally confirmed this conclusion, they also identified some effects that might being worth to be considered in future research (e.g., perceived impact and perceived social status changes were associated with changes in agreeableness after experiencing a relationship breakup). In total, our moderators explained less than 2% of variance in personality traits. Nonetheless, our study has several important implications for future research on individual differences in personality change. For example, future research should consider personal, environmental, and event-related moderators, use different analytical methods, and rely on highly powered samples to detect very small effects.

Value Fulfillment from a Cybernetic Perspective: A New Psychological Theory of Well-Being

Value Fulfillment Theory (VFT) is a philosophical theory of well-being. Cybernetic Big Five Theory (CB5T) is a psychological theory of personality. Both start with a conception of the person as a goal-seeking (or value-pursuing) organism, and both take goals and the psychological integration of goals to be key to well-being. By joining VFT and CB5T, we produce a cybernetic value fulfillment theory in which we argue that well-being is best conceived as the fulfillment of psychologically integrated values. Well-being is the effective pursuit of a set of nonconflicting values that are emotionally, motivationally, and cognitively suitable to the person. The primary difference in our theory from other psychological theories of well-being is that it does not provide a list of intrinsic goods, instead emphasizing that each person may have their own list of intrinsic goods. We discuss the implications of our theory for measuring, researching, and improving well-being.

The comforter-in-chief: How two traumatic experiences shaped president joe Biden's first 100 days

OBJECTIVE

In the first 100 days of his U.S. presidency, Joe Biden sought to comfort Americans who had lost loved ones to the pandemic and to initiate a surprisingly progressive policy agenda. I interpret these two cardinal features of his early presidency in terms of two traumatic losses in Biden's personal life, contextualizing the argument within a 3-tiered model of personality.

METHOD

This psychobiography of a single case mainly follows an inductive, grounded-theory approach that aims to find patterns in the data that both explain a life and link to evidence-based constructs in psychological science.

RESULTS

As Biden understands his own life story, the deaths of his wife and daughter in 1972 and first-born adult son in 2015 forged an empathic sensibility that enables him to connect deeply with other Americans through shared grief and pain. These two traumatic events also inform the uniquely conciliatory approach he followed to instigate social change.

CONCLUSIONS

The first 100 days of the Biden presidency provide a striking example of how a particular person's life history comes to meet the broader historical moment. The findings have implications for how personality researchers think about redemptive life stories and the nature of late-life narrative identity.

Do stimulation and support in the early childhood home environment and best friendship quality in adolescence predict adult personality?

BACKGROUND

The aim of this study was to determine whether stimulation and support in early childhood and best friendship quality in adolescence predict adult personality.

PARTICIPANTS AND PROCEDURE

We used data from 123 individuals from an ongoing longitudinal study, with multiple assessment phases and modalities (observation, parental rating, self-report) to investigate prospective associations between stimulation and support in the home in early childhood (age 1-2), best friendship quality in adolescence (age 15), and the Big Five personality traits in adulthood (age 29) controlling for temperament, socioeconomic status (SES), and gender.

RESULTS

After controlling for temperament, SES, and gender, we found that early childhood stimulation and support was related to adult openness to experiences, but not the other four traits, and that best friendship quality in adolescence was related to adult extraversion and agreeableness, but not conscientiousness, neuroticism, or openness to experiences.

CONCLUSIONS

The study contributes to research indicating that while personalities are relatively stable, they are not fixed at an early age and may be related to experiences and salient relationships throughout development. There is a dearth of research investigating such associations and the available findings are inconsistent. Conclusions about the relations between experiences such as stimulation and support in the home in early childhood or best friendship quality in adolescence and adult personality should thus be viewed skeptically until replicated.

Determinants of personal growth and life satisfaction in divorced adults

Divorce is a major life event that can trigger sudden changes in how adults perceive themselves and operate in their social environments. Some previous evidence has documented changes in personality in reaction to marital dissolution. However, little is known about the determinants of personality development in the post-divorce period. Guided by the positive personality development model in adulthood, this study examined sociodemographic characteristics, divorce-related variables and personality-related indicators as determinants of life satisfaction and personal growth in divorced adults. Participants included 460 divorced adults who completed self-reported measures regarding sociodemographic characteristics, divorce-related variables and personality development indicators. Results showed that autonomy, environmental mastery, self-acceptance, emotional self-regulation indicators and motivation for personality adjustment goals were associated with post-divorce life satisfaction. Personal growth was associated with purpose in life, self-expansion, psychological mindedness and motivation for personality growth goals. The sociodemographic characteristics and divorce-related variables differently predicted life satisfaction and personal growth. We discussed the implications of the positive personality development model in understanding post-divorce personality adjustment and maturity.

Saving Regret and Procrastination

In countries, where a substantial proportion of retirement income rests on savings, there is much concern that a sizeable fraction of the population reaches retirement with insufficient financial resources. We define saving regret as the wish in hindsight to have saved more earlier in life. We measured saving regret and possible determinants in a survey of U.S. households in which respondents were aged 60-79. We find high levels of saving regret, affirmed by some 58%. Saving regret exhibits significant and plausible correlations with personal characteristics and wealth: Married, older, healthier and wealthier respondents are less likely to report saving regret, suggesting the measure's validity. We find only weak evidence for correlations between saving regret and measures of procrastination: persons with traits associated with procrastination express saving regret about as often as those without those traits.

The relationship between parenting behavior and the personality of kindergarten children

According to Cloninger's biosocial model of personality touching upon temperament and character, personality development is a lifelong adaptive process that begins in early childhood. Similarly, theories of parenting behavior and attachment predict that associations between personality and parenting behavior should be found in young children. The present study therefore had the goal to investigate, whether associations between parenting behavior and personality in terms of Cloninger's temperament and character dimensions previously found in adolescence and adults can already be observed in kindergarten children. This study assessed personality in a sample of 324 kindergarten children (169 girls/155 boys) aged 3-6 years (M _age = 4.59, SD = 0.90). Parents rated their children's temperament and character using the JTCI 3-6 R questionnaire, which has been specifically developed to measure personality dimensions in three to six-year-olds according to Cloninger's model. Character traits (especially Self-Transcendence), which reach mature levels in adults, may not be reliably assessed in three-year-old children. Parenting behavior was documented using the DEAPQ-EL-GS self-report questionnaire measuring the parenting behavior dimensions Responsiveness and Demandingness. Correlation analyses revealed that responsive parenting behavior was positively related to the personality dimensions Reward Dependence, Self-Directedness, and Self-Transcendence. Demanding parenting behavior was positively related to the personality dimension Novelty Seeking, but negatively related to the personality dimensions Persistence, Self-Directedness and Cooperativeness. Although the cross-sectional design of our study prevents unequivocal conclusions about the causal direction of these associations, our results highlight possible differential consequences of responsive vs. demanding parenting behavior for personality development in children in line with theories of parenting behavior and attachment. Our results thus advance earlier work in adolescents and adults, by showing that parenting behavior influences the development of the child's personality according to Cloninger's biosocial model already in three to six-year-olds.

The role of personality in neighborhood satisfaction

Urbanists have long been interested in understanding what makes people satisfied with their neighborhoods. However, relatively little is known about how residents' personality traits may affect their neighborhood satisfaction. In this paper, we explore the direct and indirect associations of personality traits with neighborhood satisfaction in a representative sample of adults in Michigan (USA). We find that each of the personality traits in the five factor model are associated with neighborhood satisfaction in the same way that they are known to be associated with subjective well-being. However, we fail to observe evidence that personality traits moderate the association between perceptions of neighborhoods and neighborhood satisfaction, or that personality's association with neighborhood satisfaction is mediated by neighborhood perceptions. We conclude that there is potential for drawing on theoretical and empirical developments in positive psychology for understanding neighborhood satisfaction, but observe that the underlying mechanisms for the association between personality and neighborhood satisfaction remain unknown.

Work stress, overcommitment personality and alcohol consumption based on the Effort-Reward Imbalance model: A population-based cohort study

Work stress has been extensively supported to predict health outcomes like health behaviors. Evidence has linked work stress and personality independently to health, but the interrelationships between work stress and personality and their joint effects on health might deserve more attention in research. This study attempts to integrate recent developments in psychological research (diverse roles of personality in stress processes) into the well-established Effort-Reward Imbalance (ERI) model for work stress. Based on the ERI model, this population-based cohort study aims to investigate the relationships between work stress, personality and alcohol consumption; it particularly focuses on potential roles of overcommitment (OC) personality in ERI-drinking relations, including modifying, antecedent, mediator or direct effects. This two-wave cohort study was conducted in population samples of 3782 men and 3731 women (aged 45-69 years) from Czech Republic, Poland and Russia. Alcohol consumption was assessed by three drinking outcomes: binge drinking, heavy drinking and problem drinking. To assess modifying effect of OC in ERI-drinking relations, logistic regression was used. To assess antecedent or mediator role of OC in ERI-drinking relations, path analysis with the autoregressive and cross-lagged model was conducted. The results showed that OC had no significantly modifying effect in ERI-drinking relations. OC and ERI might have bidirectional relationships in the average follow-up period of 3.5 years; the effect of OC on ERI was remarkably stronger than the reversed causation. Antecedent role of OC in ERI-drinking relationship was significant, but mediator role of OC was not. In conclusion, our findings imply that "antecedent role" of OC in ERI-drinking relations is significant and promising as a potential target for individual intervention; future interventions are suggested to identify and target potential cognitive-behavioral mechanisms via which personality might influence work stress and subsequently health behaviors.

The Synergistic Effects of Neuroticism and Extraversion on Suicidal Ideation, Single Attempts, and Multiple Attempts in an Inpatient Sample

The current study sought to investigate the differential risk/protective factors of neuroticism and extraversion among individuals with only suicide ideation, those with a single suicide attempt, and those with multiple attempts. We hypothesized that extraversion would moderate the relation between neuroticism and suicide attempts (single and multiple) but not ideation. Patients in a private facility (N = 3343) completed measures assessing suicide history and general personality traits. Four moderation analyses were conducted with extraversion moderating the relationship between neuroticism and suicide ideation, single attempt (compared to zero attempts), and multiple attempts (compared to zero attempts and to single attempts). Extraversion moderated neuroticism only when comparing individuals with multiple suicide attempts to those with no attempts. Individuals who were low in both neuroticism and extraversion had higher levels of attempts than individuals with low neuroticism and high extraversion, highlighting the importance of considering biological predispositions as risk factors for suicide.

Self-esteem development during the transition to work: A 14-year longitudinal study from adolescence to young adulthood

INTRODUCTION

Previous studies examined the trajectory of self-esteem during critical developmental periods and over the life-span. However, little is known about how self-esteem changes during the school-to-work transition.

METHOD

We examined the effect of beginning a job for the first time on self-esteem development, using data from 368 adolescents assessed up to six times across a 14-year time span. Specifically, we analyzed the pattern of self-esteem change during the transition to work and whether the self-esteem trajectory varied as a function of several school- and job-related variables, while controlling for important covariates.

RESULTS

Results revealed linear increases in self-esteem across the 14-year study period, with partial support that the rate of increase slowed slightly after the school-to-work transition. We found significantly greater variability in the slopes after the transition, supporting the idea that people differ in the way they cope with the developmental tasks associated with important life transitions. We also found evidence for an interaction between college graduation and educational expectations, such that the positive effect of college graduation on self-esteem change was stronger for those who graduated with low (vs. high) educational expectations.

CONCLUSION

School-to-work transition has an effect on self-esteem development. Developmental processes of findings were discussed.

Do Personality Traits Moderate the Effects of Cohabitation, Separation, and Widowhood on Life Satisfaction? A Longitudinal Test for Germany

The start and end of a romantic relationship are associated with substantial changes in life satisfaction. Yet, whether Big Five personality traits moderate these relationship transition effects is hardly known. Such knowledge helps to understand individual variation in relationship transition effects and provides the possibility to further test the stress and social support explanations of these effects. Our fixed effects regressions on 28 waves of the German Socio-Economic Panel 1991-2018 show that Big Five traits moderate the effects of relationship transitions on life satisfaction to a limited extent. More neurotic men display a more negative effect of separation, and more neurotic and more agreeable women reveal a more negative effect of widowhood on life satisfaction. Big Five traits do not moderate the effect of the start of cohabitation on life satisfaction. Our findings support the stress perspective of relationship transition effects most and identify emotionally unstable individuals as a particularly vulnerable group.

Adolescence as a peak period of borderline personality features? A meta-analytic approach

This meta-analysis of cross-sectional data aimed to shed light on the often assumed peak in mean-level of borderline personality features during middle to late adolescence (i.e. age 17–22). Borderline personality features were operationalized through the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). Search terms were entered into PsycINFO and Scopus. A total of 168 samples were included in the analyses, comprising 25,053 participants. Mean age ranged from 14.35 to 51.47 years ( M = 29.01, SD = 8.52) and mean number of borderline personality features from 0 to 8.10 ( M = 4.59, SD = 2.34). The hypothesized peak between age 17 and 22 was not substantiated by the confirmatory ANOVA analysis. However, subsequent exploratory GAM analysis provided evidence for a peak at 29.4 years. Caution is needed in interpreting these findings given that different trends appeared when GAM models were constructed separately for community, patient and borderline personality disorder (BPD) samples. Age differences in community samples indicated a significant linear decline in mean-level of borderline personality features over time. A linear rising trend was found in BPD samples. As a between-person mean-level approach was used in the current study, future longitudinal studies are needed to substantiate if between-person age difference generalize to within-person changes.

Exploring variation in surgical practice: does surgeon personality influence anastomotic decision-making?

BACKGROUND

Decision-making under uncertainty may be influenced by an individual's personality. The primary aim was to explore associations between surgeon personality traits and colorectal anastomotic decision-making.

METHODS

Colorectal surgeons worldwide participated in a two-part online survey. Part 1 evaluated surgeon characteristics using the Big Five Inventory to measure personality (five domains: agreeableness; conscientiousness; extraversion; emotional stability; openness) in response to scenarios presented in Part 2 involving anastomotic decisions (i.e. rejoining the bowel with/without temporary stomas, or permanent diversion with end colostomy). Anastomotic decisions were compared using repeated-measure ANOVA. Mean scores of traits domains were compared with normative data using two-tailed t tests.

RESULTS

In total, 186 surgeons participated, with 127 surgeons completing both parts of the survey (68.3 per cent). One hundred and thirty-one surgeons were male (70.4 per cent) and 144 were based in Europe (77.4 per cent). Forty-one per cent (77 surgeons) had begun independent practice within the last 5 years. Surgeon personality differed from the general population, with statistically significantly higher levels of emotional stability (3.25 versus 2.97 respectively), lower levels of agreeableness (3.03 versus 3.74), extraversion (2.81 versus 3.38) and openness (3.19 versus 3.67), and similar levels of conscientiousness (3.42 versus 3.40 (all P <0.001)). Female surgeons had significantly lower levels of openness (P <0.001) than males (3.06 versus 3.25). Personality was associated with anastomotic decision-making in specific scenarios.

CONCLUSION

Colorectal surgeons have different personality traits from the general population. Certain traits seem to be associated with anastomotic decision-making but only in specific scenarios. Further exploration of the association of personality, risk-taking, and decision-making in surgery is necessary.

Differential personality change earlier and later in the coronavirus pandemic in a longitudinal sample of adults in the United States

Five-factor model personality traits (neuroticism, extraversion, openness, agreeableness, conscientiousness) are thought to be relatively impervious to environmental demands in adulthood. The coronavirus pandemic is an unprecedented opportunity to examine whether personality changed during a stressful global event. Surprisingly, two previous studies found that neuroticism decreased early in the pandemic, whereas there was less evidence for change in the other four traits during this period. The present research used longitudinal assessments of personality from the Understanding America Study (N = 7,109; 18,623 assessments) to examine personality changes relatively earlier (2020) and later (2021–2022) in the pandemic compared to pre-pandemic levels. Replicating the two previous studies, neuroticism declined very slightly in 2020 compared to pre-pandemic levels; there were no changes in the other four traits. When personality was measured in 2021–2022, however, there was no significant change in neuroticism compared to pre-pandemic levels, but there were significant small declines in extraversion, openness, agreeableness, and conscientiousness. The changes were about one-tenth of a standard deviation, which is equivalent to about one decade of normative personality change. These changes were moderated by age and Hispanic/Latino ethnicity, but not race or education. Strikingly, younger adults showed disrupted maturity in that they increased in neuroticism and declined in agreeableness and conscientiousness. Current evidence suggests the slight decrease in neuroticism early in the pandemic was short-lived and detrimental changes in the other traits emerged over time. If these changes are enduring, this evidence suggests population-wide stressful events can slightly bend the trajectory of personality, especially in younger adults.

Personality Development Across Adolescence and Young Adulthood: The Role of Life Transitions and Self-Concept Clarity

Personality develops across the lifespan, but most development occurs in adolescence and young adulthood. Life transitions to new social roles may be important drivers of mean-level personality development. The present study examined mean-level personality development in adolescence and young adulthood, and the role of the transition to tertiary education and working life therein in a sample of Dutch young people that were followed across 14 years ( N = 497, AgeW1 = 13.03 years). We explored whether young people’s self-concept clarity moderated these associations. Our hypotheses and analytical plan were pre-registered. Findings from Latent Growth Models showed support for maturation in personality across adolescence and young adulthood, but not a maturity dip. Having the role of employee was associated with higher conscientiousness, but no associations were found of the transition to tertiary education and the transition to work with mean-level development of any of the personality traits. Self-concept clarity did not moderate the role of transitions in mean-level personality development. Our findings suggest that socialization effects may not explain associations between life transitions and personality development in adolescence and young adulthood.

The transition to grandparenthood: No consistent evidence for change in the Big Five personality traits and life satisfaction

Intergenerational relations have received close attention in the context of population aging and increased childcare provision by grandparents. However, few studies have investigated the psychological consequences of becoming a grandparent. In a preregistered test of grandparenthood as a developmental task in middle and older adulthood, we used representative panel data from the Netherlands ( N = 563) and the United States ( N = 2210) to analyze first-time grandparents’ personality and life satisfaction development. We tested gender, employment, and grandchild care as moderators. To address confounding, we employed propensity score matching using two procedures: matching grandparents with parents and nonparents to achieve balance in different sets of carefully selected covariates. Multilevel models demonstrated mean-level stability of the Big Five personality traits and life satisfaction over the transition to grandparenthood, and no consistent moderation effects—contrary to the social investment principle. The few small effects of grandparenthood on personality development did not replicate across samples. We found no evidence of larger inter-individual differences in change in grandparents compared to the controls or of lower rank-order stability. Our findings add to recent critical re-examinations of the social investment principle and are discussed in light of characteristics that might moderate grandparents’ personality development.

Trauma Exposure and Short‐Term Volitional Personality Trait Change

OBJECTIVE

Research into post-traumatic growth (PTG) finds individuals report positive changes in their identity, relationships, and worldviews after trauma. In a pre-registered 16-week longitudinal study, we examined trait change after recent trauma exposure to test an operationalization of PTG as positive personality change. We examined the influence of intrapersonal and social factors including motivation to change traits, perceived social support, and event centrality.

METHOD

Participants (n = 1004) reported on trauma exposure in past 1-month, centrality of each traumatic event, and social support. Participants with trauma exposure (n = 146) and a matched control group reported on their traits in 8 waves at 2-week intervals, and motivation to change traits in 3 waves.

RESULTS

Although some trait change was observed, it was not consistent with PTG. We found agreeableness declined in the trauma relative to the control group among participants who did not want to change in this trait. Conscientiousness declined for individuals with highly central traumas. Social support predicted increases in emotional stability, conscientiousness, and openness but only for individuals in the control group.

CONCLUSIONS

We discuss the value of defining PTG as positive trait change and suggest future directions including assessment of facet-level changes and ideographic methods.

A study of high neuroticism in long-term survivors of childhood, adolescence, and young adult cancers

Neuroticism is a basic personality trait concerning negative feelings under stressful conditions. Our purpose was to examine the rate of high neuroticism and factors associated with high neuroticism in long-term (≥ 5 years) survivors of childhood, adolescent, and young adult cancer (CAYACSs). Norwegian CAYACSs aged 0–39 years when diagnosed and treated between 1985 and 2009 for cancer in childhood/adolescence (0–18 years), or as young adults (19–39 years) and alive in 2015 were mailed a questionnaire. Data from 1629 CAYACSs (481 children/adolescents and 1148 young adults) were analyzed. High neuroticism was found in 44% of survivors of childhood/adolescent cancers versus 34% in survivors of young adult cancer (p < 0.001). The rate of high neuroticism in female CAYACSs was 40% and in males 30% (p < 0.001). The corresponding difference between male survivor group was non-significant. In multivariable analysis, young age at survey, more adverse effects, poor self-rated health, female sex, chronic fatigue, and increased depression remained significantly associated with high neuroticism. Cancer treatment, comorbidity, and lifestyle were significant in bivariate analyses. Cancer at earlier age could increase the risk of high neuroticism among adult survivors. Screening for neuroticism could identify CAYACSs at risk for experiencing multiple health concerns and needing special follow-up attention.

How Stable, Really? Traditional and Nonlinear Dynamics Approaches to Studying Temporal Fluctuations in Personality and Affect

A pair of quantitative case studies is presented to demonstrate how different approaches to quantifying temporal variability in ratings of traits and affect can provide rich information for personality researchers. Data are presented and analyzed from two college students who completed an Ecological Momentary Assessment protocol sampling ratings of affect and traits up to 24 times daily for one week. Both classical and nonlinear data analytic techniques were applied to the data to summarize and examine the temporal dynamics of both traits and affect. For the purposes of exposition, one Big Five trait rating, extraversion, and the PANAS positive and negative affects, are discussed. The results support previous research demonstrating a high degree of variability in ratings of both traits and affect over time. Analyses using nonlinear and complexity expand on these findings and suggest temporal patterning as well as disorder; implications of phase portraits for understanding variability are discussed. The findings are discussed in light of a processing dynamics approach to resolving the role of variability in understanding personality.

Perception of major life events and personality trait change

Major life events can trigger personality trait change. However, a clear, replicable pattern of event-related personality trait change has yet to be identified. We examined whether the perception of major life events is associated with personality trait change. Therefore, we assessed young adults’ personality traits at five measurement occasions within 1 year. At the second measurement occasion, we also assessed their perception of a recently experienced major life event using the Event Characteristics Questionnaire. Contrary to our expectations, perceived impact of the event was not associated with the amount of personality trait change, but perceived valence was associated with changes in agreeableness and neuroticism. Exploratory analyses revealed some weak associations between other perceived event characteristics and the amount of personality trait change as well as interactions between perceived event characteristics and event categories in predicting changes in neuroticism. In general, effect sizes were small, and associations depended on the time interval between pre-event and post-event personality assessment. Results indicate that perceived event characteristics should be considered when examining event-related personality trait change.

The effect of perceived stress on cognition is mediated by personality and the underlying neural mechanism

Perceived stress impairs cognitive function across the adult lifespan, but the extent to which cognition decline is variable across individuals. Individual differences in the stress response are described as personality traits. Substantial individual differences in the magnitude of cognitive impairment that is induced by short-term perceived stress are poorly understood. The present study tested the hypothesis that the relationship between short-term perceived stress and different aspects of cognition is mediated by personality traits. The study included 1066 participants with behavior and neuroimaging data from the Human Connectome Project after excluding individuals with missing variables. In the result, the parallel multiple mediation model demonstrated that the influence of perceived stress on the total and crystalized cognition is mainly mediated by neuroticism (indirect effect = -0.04, p < 0.05) and conscientiousness (indirect effect = 0.05, p < 0.05) in adults. Cortical thickness value (n = 1066) of the right superior frontal gyrus (SFG) showed not only positive correlations with short-term perceived stress and neuroticism, but negative associations with cognition. The chain mediation model found that the right SFG and neuroticism play a small but significant chain mediating effect between stress and total cognition. The strength of the resting-state functional connectivity (n = 968) between the left orbitofrontal cortex versus the left superior medial frontal cortex was positively correlated with crystallized cognition and negatively associated with conscientiousness. These results extend previous findings by the impacts of short-term perceived stress on cognitive function is mediated by neuroticism and the right SFG was the underlying neural mechanism.

Facet-level changes in mothers’ neuroticism and extraversion from early pregnancy to 6 months post-partum

Becoming a parent could be expected to affect personality development, but the existing results on parenthood-personality change connection are mixed. The present study investigated 2445 primi- and multiparous mothers’ facet- and domain-level changes in Neuroticism and Extraversion from early pregnancy to 6 months post-partum, using latent difference score models. The results showed that Excitability and the affective facets of Neuroticism decreased, and the Neuroticism facets Impulsivity and Self-Consciousness increased during the follow-up. Furthermore, mother-perceived child difficult temperament attenuated desirable personality change and amplified the increases in Impulsivity. The results suggested that considering facet-level changes in personality development across significant life events is informative, and that mother-perceived child temperament may represent an important moderator of short-term personality change across the transition to parenthood.

Openness to experience is stable following adversity: A case-control longitudinal investigation

Although many people retrospectively report feeling more open-minded after experiencing highly stressful events, relevant longitudinal studies are scarce and have yielded contradictory findings. The present study used a 12-month longitudinal case-control design to test whether growth in openness (assessed every 4 months using multiple methods) occurs following major stressors, and whether changes relate to clinical symptoms of depression and/or posttraumatic stress. To do so, we compared participants (a) with a recent major stressor and with low symptoms ( n = 66), (b) without a recent major stressor and with low symptoms ( n = 76), and (c) with a recent major stressor and with significant symptoms ( n = 76). Overall, growth curve models showed that group membership was not associated with changes in openness over 12 months for most outcomes. Other variables (e.g., education) predicted changes in openness. This study provides robust evidence that openness to experience is mostly stable following major stressors.

Income moderates changes in big-five personality traits across eighteen years

The role of income in adult personality change remains poorly understood. Using latent growth modeling, we performed exploratory analyses of how longitudinal trajectories of change in personal income and the Big Five personality traits would be related. We examined 4234 participants (2149 Males, 2085 Females; MT1age = 46.42, SDT1age = 13.36, age range at T1: 20–74 years) across three time points spanning 18 years using data from the Midlife in the United States study. Results indicated that starting levels of income moderated changes in four personality traits. Specifically, income moderated the slopes of openness to experience, extraversion, agreeableness, and neuroticism, such that for high-income individuals, openness to experience, extraversion, and agreeableness were less likely to decline and more likely to either increase or remain stable over time, while neuroticism was less likely to increase and more likely to remain stable over time. Conversely, personality traits were weaker predictors of income change as slopes of income were not moderated by starting levels of any of the personality traits. Moreover, changes in income were not correlated with changes in any of the personality traits. The findings suggest that individual differences in income could potentially explain diverging trajectories of personality change.

How are common major live events perceived? Exploring differences between and variability of different typical event profiles and raters

Research on major life events and personality change often focuses on the occurrence of specific life events such as childbirth, unemployment, or divorce. However, this typical approach has three important limitations: (1) Life events are typically measured categorically, (2) it is often assumed that people experience and change from the same event in the same way, and (3) external ratings of life events have unknown levels of validity. To address these limitations, we examined how common life events are typically perceived, how much perceptions of life events vary within events, and how well external ratings of events correspond to subjective ratings from people who experienced the events. We analyzed ratings of nine psychologically relevant characteristics of 10 common major life events from three different types of raters ( N = 2,210). Each life event had a distinct subjectively rated profile that corresponded well to external ratings. Collectively, this study demonstrates that life events can be meaningfully described and differentiated with event characteristics. However, people’s individual perceptions of life events varied considerably even within events. Therefore, research on major life events and their associations with personality change should incorporate individual perceptions of the events to advance the understanding of these associations.

Personality and Everyday Functioning in Older Adults With and Without HIV

In a cross-sectional multi-method study of older adults living with and without HIV (n = 202; 69.8% HIV seropositive), we tested associations between personality traits and everyday functioning, and whether these associations differed depending on HIV serostatus. We found that higher levels of conscientiousness and lower levels of neuroticism were associated with higher odds of being clinically independent (vs. dependent) in everyday functioning. These findings replicated across self- and clinician-reports and persisted above and beyond relevant covariates. We found no evidence of interactions between personality and HIV serostatus, suggesting that personality was equally important for everyday functioning regardless of HIV serostatus. Given the present findings and the knowledge that personality is dynamic and amenable to intervention, we discuss two different possible pathways for intervention meant to improve everyday functioning and quality of life among older adults with and without HIV: personality change and personalized medicine.

Educational stays abroad and the development of self-perceived grit: A longitudinal analysis in young adulthood

Grit can be viewed as a facet of conscientiousness consisting of the two sub-facets perseverance of effort and consistency of interest. Although ample research illustrates the importance of grit for educational attainment, little is known about its developmental trajectories. The goal of the present study was to examine the development of self-perceptions in the two grit facets during educational stays abroad in young adulthood. We measured grit in a sample of 179 German sojourners, who went abroad for some type of educational stay, immediately before the start of their stay abroad (T1), 3 months afterwards (T2), and 15 months afterwards (T3). We compared the developmental trajectories across T1 and T2 with a control group of 112 Germans staying at home during this period. Multivariate latent change score models showed an increase in perseverance of effort between T1 and T2 in the group of sojourners, which did not emerge in the control group and persisted throughout T3. Consistency of interest did not change between T1 and T2, but sojourners showed an increase in consistency of interest between T1 and T3. This change was positively predicted by the time sojourners had spent abroad. Although we found different developmental trajectories for perseverance of effort and consistency of interest, substantial correlated change between these facets indicated similar processes to account for change in both traits. We discuss implications for research on the development of grit as well as the role of educational stays abroad.

No party no joy?-Changes in university students' extraversion, neuroticism, and subjective well-being during two COVID-19 lockdowns

The COVID-19 lockdowns represent a major life event with an immense impact on university students' lives. Findings prior to the pandemic suggest that changes in personality and subjective well-being (SWB) can occur after critical life events or psychological interventions. The present study examined how university students' extraversion, neuroticism, and SWB changed during two COVID-19 lockdowns in Germany. To this end, we conducted a partly preregistered, two-cohort study with four measurement points each from October 2019 to May 2021 (N_{Study 1}  = 81-148, N_{Study 2}  = 82-97). We used both multilevel contrast analyses and multi-group random-intercept cross-lagged panel models to examine within-person changes over time. Levels of life satisfaction, extraversion, and, unexpectedly, neuroticism were lower during both lockdowns. Students' affect improved during the first but deteriorated during the second lockdown, suggesting that similar experiences with the deceleration of daily life were associated with different affective outcomes during the two lockdown periods. Following the introduction or termination of a lockdown, changes in extraversion (neuroticism) were consistently positively (negatively) associated with changes in SWB. Our results stress the importance of disentangling between- and within-person processes and using pre-COVID baseline levels to examine changes in personality and SWB.

Awareness of age-related change in the context of major life events

Although gains and losses are an integral part of human development, the experience of change and readjustment that often comes with major life events may be particularly influential for an individual's subjective aging experience and awareness of age-related change (AARC). Thus, this study focused on the role of life events in the domains of family and health for an individual's awareness of age-related gains and losses. Specifically, we differentiated between the experience of specific life events (e.g., entering a new romantic relationship; hospital stay) and the cumulative experience of multiple life events. Furthermore, we differentiated between life events experienced at an expected time in life and life events experienced relatively early or relatively late compared to established social norms. Data came from the Innovation Sample of the German Socio-Economic Panel (SOEP-IS) and consisted of 1,612 participants aged 16 to 93 years (M = 54.1; SD = 18.2). Life events were assessed annually and retrospectively for the last 2 years. Propensity score matching provided evidence for an association of specific family life events and a higher awareness of age-related gains, as well as specific health life events and a higher awareness of age-related losses. Results furthermore indicated that the cumulative experience of family life events was associated with a higher awareness of age-related gains. Conversely, the cumulative experience of health events was associated with higher awareness of both age-related losses and age-related gains. Moreover, it was not only life events happening at an expected age, but also those happening relatively early and particularly those happening late in life, which were associated with AARC. In summary, life events and the change they may bring seem to be reflected in individuals' awareness of age-related losses and awareness of age-related gains.

Advancing a Three-Tier Personality Framework for Posttraumatic Growth

Adversity has been assumed to foster positive personality change under certain conditions. In this article, we examine this assumption within the context of the three-tier personality framework integrating traits, characteristic adaptations, and narrative identity to provide a comprehensive understanding of personality growth. We first review findings on how adverse events affect personality on each of these three levels. Second, we summarize knowledge on event-based and person-based predictors of personality change in the face of adversity. Third, we specify affective, behavioral, and cognitive processes that explain personality change across levels of personality. Innovatively, our proposed process model addresses change at all three levels of personality, as well as similarities and differences in processes across the levels. We conclude by discussing unresolved issues, asking critical questions, and posing challenging hypotheses for testing this framework.

The Mediating Effect of Social Problem-Solving Between Perfectionism and Subjective Well-Being

This study examined the relationship between perfectionism and subjective well-being (SWB) and dimensions of social problem-solving ability. The Almost Perfect Scale-Revised (APS-R), Social problem-solving Inventory-Revised (SPSI-R) and Satisfaction with Life Scale (SWLS) were used to conduct a questionnaire survey of 202 Chinese adults. The results found that: (1) Subjective well-being was significantly negatively correlated with the discrepancy dimension of perfectionism and was also significantly negatively correlated with the negative problem orientation of social problem-solving. (2) The discrepancy dimension reflected in maladaptive perfectionism was significantly positively correlated with the negative aspects of social problem solving (Negative Problem Orientation, NPO; Impulsivity-Carelessness Style, ICS; and Avoidance Style, AS). (3) The negative problem orientation (NPO) dimension in SPSI-R, as a partial mediator, mediated the negative correlation between maladaptive perfectionism and subjective well-being. In conclusion, perfectionism and social problem-solving ability had different degrees of influence on the SWB of Chinese adults, and attention could be paid to dealing with discrepancy and how to reduce negative problem-solving tendency in education and clinical practice.

Publishing quantitative careers research: challenges and recommendations

Purpose

This article aims to provide prospective authors guidelines that will hopefully enable them to submit more competitive manuscripts to journals publishing careers research.

Design/methodology/approach

Based on their experience as an author, reviewer and editorial team member, the authors identify the main criteria that a quantitative study must meet to be considered for publication in international peer-reviewed journals covering career-related topics. They emphasize the importance of contributing to the careers literature and of designing the study in accordance with the research question.

Findings

Manuscripts are rejected because they are insufficiently innovative, and/or because sample, instruments and design are not appropriate to answer the research question at hand. Cross-sectional designs cannot be used to answer questions of mediation but should not be discarded automatically since they can be used to address other types of questions, including questions about nesting, clustering of individuals into subgroups, and to some extent, even causality.

Originality/value

The manuscript provides an insight into the decision-making process of reviewers and editorial board members and includes recommendations on the use of cross-sectional data.

Stability of and change in substance use risk personality: Gender differences and smoking cigarettes among early adolescents

OBJECTIVE

Adolescents show a steadily increasing inclination toward health risk behaviors, including smoking cigarettes. There is ample evidence that personality traits are related to smoking behavior. However, less is known about the stability of and change in these personality traits during early adolescence and whether smoking behavior affects the developmental trajectories. Moreover, less is known about the influence of gender on the course of personality.

METHOD

Longitudinal data of three waves were used from 1121 early adolescents. To measure personality, the Substance Use Risk Profile Scale was used. Individual growth curve models were conducted to measure the stability, mean-level change and individual differences in change for personality.

RESULTS

Stability of personality was moderate for boys and ranged from moderate to high for girls. On average early adolescents became more impulsive and more sensation seeking over a period of 18 months. Furthermore, hopelessness for girls increased and the increase in sensation seeking was higher for girls than for boys. Third, smoking behavior was related to all personality traits, indicating that smoking adolescents are more anxious, hopeless, impulsive and sensation seeking than non-smoking adolescents.

CONCLUSIONS

Our results are in line with the disruption hypothesis, i.e., during early adolescence there is a dip in personality maturity. There are clear differences between girls and boys in stability of and change in personality traits. Besides, although smoking behavior is related to personality, the change in personality is probably related to other variables.

Detecting Idiographic Personality Change

Personality changes across the lifespan, but strong evidence regarding the mechanisms responsible for personality change remains elusive. Studies of personality change and life events, for example, suggest that personality is difficult to change. But there are two key issues with assessing personality change. First, most change models optimize population-level, not individual-level, effects, which ignores heterogeneity in patterns of change. Second, optimizing change as mean-levels of self-reports fails to incorporate methods for assessing personality dynamics, such as using changes in variances of and correlations in multivariate time series data that often proceed changes in mean-levels, making variance change detection a promising technique for the study of change. Using a sample of N = 388 participants (total N = 21,790) assessed weekly over 60 weeks, we test a permutation-based approach for detecting individual-level personality changes in multivariate time series and compare the results to event-based methods for assessing change. We find that a non-trivial number of participants show change over the course of the year but that there was little association between these change points and life events they experienced. We conclude by highlighting the importance in idiographic and dynamic investigations of change.

Conceptualizing and Studying Characteristics, Units, and Fits of Persons and Environments: A Coherent Synthesis

Based on a perspective on personality coherence as the extent to which personality-relevant characteristics are differentiated and integrated within a person in his or her environment, we propose a synthesis that builds on and harmonizes existing and partly conflicting theories, methodological approaches, and empirical findings. This understanding of personality coherence needs clear definitions of person and environment characteristics. We define traits as characteristics of the person, adaptations as characteristics of the person-in-contexts, and states as characteristics of the person-in-situations. Thus, our synthesis involves concepts of environments and person-environment units. Next, we provide testable criteria to differentiate characteristics of persons from characteristics of person-environment units and to identify dispositional traits for a narrow-sense perspective on personality coherence. We raise awareness of the importance of fit between (profiles of) person and environment characteristics for an understanding of the integrated uniqueness of persons in their environments. We outline implications of this broader perspective on personality coherence for personality development, self-regulation, social integration, well-being, and psychological interventions. Lastly, we conclude that the analysis of an individual’s uniqueness and personality differences requires information about how well-defined, well-differentiated, well-integrated, and well-operationalized person(ality) variables are actually expressed in, or interact and transact with, the individual environment.

Personality Traits and Perceptions of Major Life Events

Research examining the associations between major life events and personality trait development is mixed. Work that evaluates perceptions of life events and how those perceptions are themselves associated with personality traits may help clarify the existing literature. We used a large student sample ( N = 1,509) and a demographically diverse sample from a Qualtrics panel ( N = 552) to conduct exploratory analyses examining the associations between the big five personality traits and perceptions of life events. Results suggested that (a) associations between personality and beliefs about event-related personality change differ between students and more representative samples, (b) associations between personality and event perceptions are often nuanced, and (c) event perceptions are not merely proxies for personality traits. These studies highlight the importance of subjective event perceptions in the study of major life events and personality.

Mindful of personality trait change: Are treatment effects on personality trait change ephemeral and attributable to changes in states?

OBJECTIVE

Are treatment effects on personality trait change ephemeral and attributable to change in clinical states? Data of an intervention study were used to examine if change in clinical states (e.g., stress or depression) accounts for change in personality traits and to test whether both changes in traits and clinical states were independently associated with substance use.

METHOD

Seventy-nine substance use patients (M_age = 25.3, SD = 2.7; 35% female) took part at a 4-week intervention and completed a total of 15 bi-monthly assessments across 28 weeks to measure change in traits and states during and after treatment.

RESULTS

The results suggest that participants showed large trait and state changes over time, which happened rapidly with the majority occurring during the first four weeks. Trait and state changes were highly correlated, but not perfectly redundant. Significant variance in personality trait change remained after controlling for change in clinical states. Moreover, both trait and state change independently predicted substance use.

CONCLUSION

Personality trait change occurred relatively fast and was maintained until the last follow-up assessment six months after the end of the intervention. Also, the findings point to the notion that the conceptual distinction between traits and states may not be as important as originally thought.

Perceived Characteristics of Life Events—Short-Term Changes in Prosociality and Empathy?

Post-traumatic growth can be understood as positive change in desirable personality traits after adverse life events. However, recent research questioned whether adversity is a relevant, necessary, and sufficient condition for change in desirable personality traits. Using five-wave longitudinal data, this study explored changes in the desirable personality traits prosociality and empathy before and after life events. We included all life events participants had experienced between the second and third assessment, that is, adverse, ambiguous, and positive events. Participants rated their life events on the Event Characteristics Questionnaire which assesses the individual perception of life events on nine continuous dimensions: challenge, emotional significance, extraordinariness, external control, impact, valence, social status change, predictability, and change in world views. We used multilevel growth curve models to explore changes in prosociality and empathy as a function of these event characteristics. Prosociality and empathy remained stable in the assessment period of 6 to 9 months after the reported life event, independently of whether the event had been perceived as adverse or not. We discuss our findings with respect to the inclusion of positive and ambiguous events as predictors of personality change and with respect to its theoretical implications for post-traumatic growth and personality development more broadly.

Personality Traits and Sense of Dignity in End-of-Life Cancer Patients: A Cross-Sectional Study

CONTEXT

Patients' personality traits can play an important role in the end-of-life care process.

OBJECTIVES

The present study aimed to investigate the relationship between personality traits and dignity in cancer patients nearing death. In addition, the associations between personality traits and physical, psychological symptoms, and coping strategies during the end-of-life stage were explored.

METHODS

The study is cross-sectional. The sample consisted of 210 participants with a Karnofsky Performance Status (KPS) lower than 50 and a life expectancy of a few weeks. For each patient, personal and clinical data were collected and a set of validated rating scales, assessing personality, dignity, physical, psychological symptoms and coping strategies was administered during the first psychological consultation.

RESULTS

The results highlighted significant associations between personality traits and dignity. In particular, Conscientiousness was negatively correlated with Social Support and Extroversion was negatively associated with Loss of Purpose and Meaning. Neuroticism was related to all the dimensions of dignity and Extroversion was significantly associated with the physical and psychological symptoms. Regarding coping styles, active coping strategies were predictors of Extroversion and Agreeableness. Conversely, anxiety symptoms predicted the Neuroticism trait.

CONCLUSIONS

Personality traits seem to be actively involved into the loss of dignity. These findings highlighted the importance of including personality traits and dignity into the patient's care process. Exploring individual differences and coping mechanisms at the end-of-life could improve palliative care and lead to better patient-tailored psychological interventions.

Open to Contact? Increased State Openness Can Lead to Greater Interest in Contact With Diverse Groups

Contact is a reliable method of prejudice reduction. However, individuals higher in prejudice are less interested in contact with diverse groups. This research investigates a novel method of encouraging interest in contact, particularly for those lower in the personality trait of Openness/Intellect, who tend to be higher in prejudice. Although long-term traits are relatively stable, momentary personality states show considerable within-person variation, and can be manipulated. In two experimental studies (total N = 687), we tested whether inducing higher state Openness would affect interest in contact. In Study 1, those lower in trait Openness/Intellect showed a positive indirect effect of condition on two outcome measures, via greater state Openness. In a larger sample with lower trait Openness/Intellect (Study 2), the indirect effect on the first outcome was replicated, regardless of disposition. The findings suggest that experiencing open states more frequently could encourage contact and lead to eventual reductions in prejudice.
