Is Conscientiousness Always Associated With Better Health? A U.S.-Japan Cross-Cultural Examination of Biological Health Risk

In Western societies, conscientiousness is associated with better health. Here, we tested whether this pattern would extend to East Asian, collectivistic societies. In these societies, social obligation motivated by conscientiousness could be excessive and thus health-impairing. We tested this prediction using cross-cultural surveys of Americans (N = 1,054) and Japanese (N = 382). Biomarkers of inflammation (interleukin-6 and C-reactive protein) and cardiovascular malfunction (systolic blood pressure and total-to-HDL cholesterol ratio) were adopted to define biological health risk (BHR). Among Americans, conscientiousness was associated with lower BHR. Moreover, this relationship was mediated by healthy lifestyle. In contrast, among Japanese, the relationship between conscientiousness and BHR was not significant. Further analysis revealed, however, that conscientiousness was associated with a greater commitment to social obligation, which in turn predicted higher BHR. These findings suggest that conscientiousness may or may not be salubrious, depending on health implications of normatively sanctioned behaviors in varying cultures.

Childhood socioeconomic status and inflammation: Psychological moderators among Black and White Americans

OBJECTIVE

The current study examined race differences in how childhood socioeconomic status (SES) predicted midlife inflammation. It also tested psychological resources (purpose in life, optimism, and conscientiousness) as moderators of the association between childhood SES and inflammation among Black and White adults.

METHOD

Data came from the biomarker subsamples of the Midlife in the United States Core and Refresher studies (n = 1,578 White and n = 395 Black participants). Childhood SES was operationalized as a composite of parental education, perceived financial status, and welfare status. Outcomes included circulating IL-6 and CRP.

RESULTS

Childhood SES did not predict IL-6 or CRP among Black or White adults in fully adjusted models. Among Black adults with low optimism, lower childhood SES predicted higher IL-6 and CRP. Among Black adults with low purpose in life, lower childhood SES predicted higher CRP (but not IL-6). Conscientiousness did not moderate childhood SES-inflammation associations among Black adults. Among White adults with low conscientiousness or low optimism, lower childhood SES predicted higher IL-6 (but not CRP). Purpose in life did not moderate associations among White adults. Effect sizes were small (≤1% variance explained) and comparable to effects of clinical risk factors in this sample (e.g., age, chronic conditions).

CONCLUSIONS

Race differences in the childhood SES and inflammation association were not apparent. Childhood SES was linked to inflammation more strongly among those with fewer psychological resources across both racial groups. Psychological resources may be important moderators of inflammation in the context of early life SES disadvantage. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Neuroticism, conscientiousness, and in vivo Alzheimer pathologies measured by amyloid PET and MRI

AIM

It has been suggested that personality traits, particularly neuroticism and conscientiousness, are risk factors for Alzheimer's disease (AD) and related cognitive decline. However, the underlying pathological links between personality traits and AD-related cognitive impairments remain unclear. Thus, the present study investigated associations of neuroticism and conscientiousness with in vivo cerebral amyloid-beta (Aβ) burden, AD-signature regional neurodegeneration, and white matter hyperintensities (WMH) in non-demented middle- and old-aged adults.

METHODS

A total of 397 non-demented participants underwent comprehensive clinical and neuropsychological assessments, ¹¹ C-labeled Pittsburgh Compound B positron emission tomography, and magnetic resonance imaging. Additionally, the NEO Five-Factor Inventory was administered to both the participants and their informants to measure neuroticism and conscientiousness.

RESULTS

Neither neuroticism nor conscientiousness was associated with cerebral Aβ deposition or WMH. In contrast, higher neuroticism and lower conscientiousness, reported by informants in particular, were significantly associated with reduced AD-signature region cortical thickness. In regards to the direct and indirect effect of each personality on AD-signature region cortical thickness, only the direct effects were found, whereas indirect effects via Aβ deposition or WMH were not.

CONCLUSION

The present findings suggest that amyloid-independent regional neurodegeneration might underlie relations of neuroticism and conscientiousness with AD.

Inhibition tasks are not associated with a variety of behaviors in college students

Executive functioning (EF) is defined as a set of top-down processes used in reasoning, forming goals, planning, concentrating, and inhibition. It is widely believed that these processes are critical to self-control and, therefore, that performance on behavioral task measures of EF should be associated with individual differences in everyday life outcomes. The purpose of the present study was to test this core assumption, focusing on the EF facet of inhibition. A sample of 463 undergraduates completed five laboratory inhibition tasks, along with three self-report measures of self-control and 28 self-report measures of life outcomes. Results showed that although most of the life outcome measures were associated with self-reported self-control, only one of the outcomes was associated with inhibition task performance at the latent-variable level, and this association was in the unexpected direction. Furthermore, few associations were found at the individual task level. These findings challenge the criterion validity of lab-based inhibition tasks. More generally, when considered alongside the known lack of convergent validity between inhibition tasks and self-report measures of self-control, the findings cast doubt on the task's construct validity as measures of self-control processes. Potential methodological and theoretical reasons for the poor performance of laboratory-based inhibition tasks are discussed.

Expanding the Scope of Implicit Personality Assessment: An Examination of the Questionnaire-Based Implicit Association Test (qIAT)

Self-report questionnaires can only yield information that people are able and willing to report, but implicit assessment methods are not commonly used in mainstream personality research. The Questionnaire-based Implicit Association Test (qIAT) was designed to address the limitations associated with the conventional self-concept IAT, and it enables an indirect assessment that is based on the items of standard self-reports. The present studies examined the psychometric properties of the qIAT across two personality constructs. Study 1 (N = 528) provided support for the internal consistency, test-retest reliability and convergent and discriminant validity of the qIAT that measured extraversion. Study 2 (N = 164) supported the reliability and validity of the qIAT assessment of conscientiousness, which predicted who returned to complete the second session of the study two weeks later, for which participants were paid in advance. This same prediction effect was marginally significant in Study 3 (N = 200), and across both Studies 2 and 3 the qIAT prediction of the criterion behavior was incremental to the parallel self-report questionnaire. Taken together, findings support the reliability and validity of the qIAT, which enables the indirect measurement of a wide variety of distinct personality constructs, currently measured only by self-report scales.

Speed of Processing and Personality: The Influence of Personality and Extrinsic Feedback on the Performance of Cognitive Tasks

Background: Feedback is considered as an effective means of motivating, guiding, and reinforcing desired behaviours. However, the ways to interpret external feedback may be different among individuals with different personality traits; therefore, this would influence the effects of feedback on performance. Accordingly, the influencing effects of personality towards different styles of feedback on cognitive task performance were examined. Methods: Participants (N = 71) were given three Stroop tasks as a dependent variable, whereas the Trail Making Task was an independent variable; additionally, a personality test was used to record the personality traits of each participant. The relationship between personality and feedback-induced changes in Stroop performance was computed by means of Pearson correlation, followed by a mixed-effect model to demonstrate the effect of personality on the overall performance with feedback. Results: The statistical analysis indicated that performance from those with higher levels of extraversion generally profitted from feedback, irrespective of whether it was negative feedback (r = 0.201) or positive feedback (r = 0.205). Additionally, the moderating effect of personality on feedback and performance was demonstrated. Conclusions: The limitations of the sample size and other external influences may have reduced the representativeness of the research. Nonetheless, more potential influencing factors need to be included and explored in future research.

Personality Traits and Psychopathology Over the Course of Six Months of Outpatient Psychotherapy: A Prospective Observational Study

There is a lack of prospective studies that test pre-specified hypotheses on the role of personality traits in outpatient psychotherapy. A total of 47 patients with a broad range of psychopathological syndromes were enrolled in a prospective 6-month observational study conducted in Zurich, Switzerland. We found evidence for remarkably high differential stability in all Big Five personality traits during the first 6 months of psychotherapy. Mean-level stability was very high in agreeableness and conscientiousness, while modest changes were observed in neuroticism, extraversion and openness. Baseline scores in neuroticism and conscientiousness at the beginning of therapy predicted modest change in self-reported severity of psychopathology over 6 months, but no effect was found in association with therapist-rated functional deficits. We conclude that personality trait levels may change slightly over the course of 6 months of psychotherapy and that both neuroticism and conscientiousness may have weak associations with the self-perceived improvement in psychopathology.

Parent-Reported Personality and Weight Transitions across Adolescence

Background: Adolescence is a critical transition point for body weight. Personality traits are associated consistently with weight and obesity risk in adulthood. We examined whether personality, particularly Conscientiousness (the tendency to be organized, disciplined, and responsible), is associated with weight outcomes between ages 13 and 17. Methods: Data are drawn from the Growing Up in Ireland suites of studies. Parents rated their child's personality at age 13, and trained staff measured weight and height at ages 13 and 17 (N = 4962). Logistic regression was used to predict risk of incident obesity and obesity remission between ages 13 and 17. Results: Among children who were not in the obesity category at age 13, higher Conscientiousness was associated with lower risk of moving into the obesity category by age 17, and, among children with obesity at age 13, Conscientiousness was associated with greater likelihood of moving to the nonobesity category by age 17. These associations were independent of sociodemographic characteristics, parent body mass index, and were similar across gender. The other five-factor model personality traits were unrelated to weight outcomes. Conclusions: Conscientiousness is one trait psychological factor implicated in weight transitions across a critical period during adolescence.

Effect of Discrimination on Presenteeism among Aging Workers in the United States: Moderated Mediation Effect of Positive and Negative Affect

This study aimed to examine how perceived everyday discrimination influences presenteeism and how conscientiousness moderates the relationship between discrimination and positive affect among older workers. Structural equation modeling (SEM) was used to examine the mediating effect. The moderated mediation model was examined by PROCESS. The results of the final SEM model showed that discrimination was directly positively associated with presenteeism. Furthermore, positive affect was significantly inversely correlated with discrimination and presenteeism. In addition, negative affect was significantly positively correlated with discrimination and presenteeism. The significant indirect effect between perceived everyday discrimination and positive affect was significantly mediated by positive and negative affect. In addition, the results of the moderated mediation model indicate that positive affect was more likely to be influenced by perceived everyday discrimination among older workers with less conscientiousness, as compared with those with greater conscientiousness. To enhance work outcomes of aging workers in the United States, managers should foster highly conscientious aging workers, award those who are hardworking and goal-oriented, and combine personal goals and organizational goals through bonuses, holidays, and benefits. Policymakers should be mindful of the negative impact of discrimination on presenteeism and should target lowly conscientious older workers.

Personality traits as an organizing framework for personality pathology

We review evidence establishing important parallels between the general structure of psychopathology, the more specific structure of personality pathology and the structure of normal-range personality. We then present data to explicate the nature of associations between the alternative model of personality disorder (AMPD)-as operationalized by the Personality Inventory for DSM-5-and the domains and facets subsumed within the five-factor model of personality. Our data demonstrate substantial links between four of the five domains within these models but also indicate that the AMPD could be realigned to enhance its convergence with the five-factor model of personality. Based on our data, we tentatively propose an expanded four-facet model of AMPD Negative Affectivity (Anxiousness, Depressivity, Hostility and Emotional Lability); an alternative bipolar scheme for Detachment that includes two positively keyed (Withdrawal and Anhedonia) and two negatively keyed (Risk Taking and Attention Seeking) facets; a broader five-facet model of Antagonism (Deceitfulness, Manipulativeness, Callousness, Grandiosity and Suspiciousness); and a reduced two-facet model of Disinhibition (Irresponsibility and Impulsivity). These alternative scores generally showed superior convergent and discriminant validity when compared with current measures of the AMPD domains but also raise other issues. Our findings highlight the strong overlap between normal and pathological personality and clarify the nature of the associations between them. © 2019 John Wiley & Sons, Ltd.

MindHike, a Digital Coaching Application to Promote Self-Control: Rationale, Content, and Study Protocol

This protocol describes a study that will test the effectiveness of a 7-week non-clinical digital coaching intervention to promote self-control. The goal of the coaching is to support and guide people who are willing and motivated to improve their self-control with the help of the smartphone application MindHike. The coaching is based on a process model of self-control and aims to target five groups of self-control strategies. The goal of the study is to examine the effectiveness of the digital coaching intervention. A single-arm study design with pre-test, post-test and 2-month follow-up assessments and process assessments will be used to evaluate the 7-week digital coaching intervention. The digital coaching includes 49 daily lessons that are organized along 7 weekly core themes. Study participants will be at least 150 adults aged 18 years and older who are willing and motivated to improve their self-control using the MindHike application. This is the first study testing the effectiveness of a digital coaching intervention to promote self-control. Given that this approach proves effective, it could be easily implemented in various non-clinical settings such as education, health, relationship, and work, and in clinical settings. Due to its digital low-threshold character, it could also reach large numbers of people.

Beyond the Categorical Distinction Between Borderline Personality Disorder and Bipolar II Disorder Through the Identification of Personality Traits Profiles

BACKGROUND

The relationship between borderline personality disorder (BPD) and type-II bipolar disorder (BDII) is not clearly understood. Nevertheless, in clinical practice and research, most efforts focus on establishing a categorical distinction between the two. We propose using personality traits as a more informative strategy to describe them.

METHODS

Five-Factor Model personality traits were measured in 73 individuals with either BPD or BDII. Latent class cluster analysis was applied to the sample.

RESULTS

A three-cluster model resulted the best fit to the data, where all clusters had high neuroticism and low extraversion scores but differed widely on the other traits. The clusters' boundaries did not match the categorical diagnosis.

CONCLUSIONS

Our sample showed significant heterogeneity on personality traits, which can have a relevant effect on the outcome of each disorder and that was not captured by the categorical diagnosis. Thus, we advocate for a multivariate approach as a better way to understand the relationship between BPD and BDII.

Personal Belief in a Just World and Conscientiousness: A meta-analysis, facet-level examination, and mediation model

Extensive research efforts have been devoted to understanding the nature of Conscientiousness, the only Big Five personality trait that has been robustly linked to professional achievement and longevity. We proposed that Conscientiousness is associated with Personal Belief in a Just World (PBJW), that is, the extent to which an individual believes that her or his efforts will be rewarded. To investigate this proposition, we undertook a meta-analysis synthesizing past findings regarding the relationship between PBJW and Conscientiousness; we confirmed a positive relationship between the two constructs (r = .16) based on 17 samples and 5,810 individuals. We further proposed a theoretical framework linking PBJW to specific facets of Conscientiousness. A survey of a representative sample of the US population (n = 311) confirmed that PBJW is positively correlated with the specific facets of Self-efficacy, Achievement-striving, and Self-discipline. Internal Locus of Control mediated these associations, elucidating the underlying processes linking PBJW and Conscientiousness.

Individual Differences in Mental Accounting

Individual differences in mental accounting have rarely been studied, and empirical evidence regarding the relation between mental accounting and personality characteristics is scarce. The present paper reports three studies applying a Likert-type scale to assess the extent individuals engage in mental accounting practices. In each study, the five items of the measure loaded on a single dimension and had acceptable reliability, with a Cronbach's α between 0.72 and 0.77. Study 1 (N = 165) regards the mental processing of prior losses in the theater-ticket problem (Tversky and Kahneman, 1981). Study 2 (N = 114) is based on prior work on income source effects (Fogel, 1997) and analyzes mental accounting of prior gains. In both studies, individual differences in mental accounting moderated the effects of the experimental treatments. In an explorative survey conducted for Study 3 (N = 373), the extent of engaging in mental accounting was found to be positively correlated with being female, with conscientiousness, and financial literacy, and negatively related with education and non-planning impulsivity. Identification of individual differences and their correlates adds to existing evidence for some of the core assumptions of mental accounting theory. A practical implication of the findings is that providers of financial services must take individual differences into account when designing trainings and supportive tools for money management.

A century of research on conscientiousness at work

Evidence from more than 100 y of research indicates that conscientiousness (C) is the most potent noncognitive construct for occupational performance. However, questions remain about the magnitudes of its effect sizes across occupational variables, its defining characteristics and functions in occupational settings, and potential moderators of its performance relation. Drawing on 92 unique meta-analyses reporting effects for 175 distinct variables, which represent n > 1.1 million participants across k > 2,500 studies, we present the most comprehensive, quantitative review and synthesis of the occupational effects of C available in the literature. Results show C has effects in a desirable direction for 98% of variables and a grand mean of [Formula: see text] (SD = 0.13), indicative of a potent, pervasive influence across occupational variables. Using the top 33% of effect sizes [Formula: see text] we synthesize 10 characteristic themes of C's occupational functioning: 1) motivation for goal-directed performance, 2) preference for more predictable environments, 3) interpersonal responsibility for shared goals, 4) commitment, 5) perseverance, 6) self-regulatory restraint to avoid counterproductivity, and 7) proficient performance-especially for 8) conventional goals, 9) requiring persistence. Finally, we examine C's relation to performance across 8 occupations. Results indicate that occupational complexity moderates this relation. That is, 10) high occupational complexity versus low-to-moderate occupational complexity attenuates the performance effect of C. Altogether, results suggest that goal-directed performance is fundamental to C and that motivational engagement, behavioral restraint, and environmental predictability influence its optimal occupational expression. We conclude by discussing applied and policy implications of our findings.

Personality Traits and Self-Esteem in Combat and Team Sports

The aim of this research was to examine whether psychological variables which make up basic dimensions of personality and self-esteem distinguish competitors in combat sports from competitors in team sports. The research included 149 respondents, aged 19 to 27 years. The Self-Esteem Scale questionnaire was used to measure self-esteem. The BFI inventory was used to measure personality traits according to the Big Five model: Extraversion, Neuroticism, Conscientiousness, Agreeableness, and Openness to Experience. The basic research question is – does the set of psychological variables which make up basic dimensions of personality and self-esteem statistically significantly distinguish competitors in combat sports from the competitors in team sports? Both mean differences and simple discriminant function analyses for competitors in combat/team sports revealed that self-esteem, neuroticism, and conscientiousness were the most important factors distinguishing the two groups. Practical implications, limitations, and future research directions were discussed.

Mind the Silver Bullet Thinking: A Multilevel Study on the Impact of Manager Trait Mindfulness on Subordinate Objective Job Performance

This research examines the relationship between trait mindfulness of managers and job performance of their subordinates. We hypothesized that both are positively associated and that this association exist when personality variables are controlled for. We tested our hypotheses in a sample of 40 line managers and their 487 subordinates working in 40 teams within the customer service division of an energy company. We measured managers' trait mindfulness using the Five Factor Mindfulness Questionnaire (FFMQ) and managers' neuroticism and conscientiousness using the NEO-FFI. We obtained objective data of each subordinate's job performance captured by the company's KPIs assessed monthly over a period of 6 months. We used multilevel regression analyses to test our hypotheses. Results did not support our hypotheses, the regression coefficient from managers' trait mindfulness to subordinates' job performance was close to zero and insignificant. In the context of previously reported positive findings, our results suggest that the contribution of trait mindfulness to subordinates' performance might not exist or could be contingent on contextual factors.

Preference for realistic art predicts support for Brexit

Following the UK's EU referendum in June 2016, there has been considerable interest from scholars in understanding the characteristics that differentiate Leave supporters from Remain supporters. Since Leave supporters score higher on conscientiousness but lower on neuroticism and openness, and given their general proclivity toward conservatism, we hypothesized that preference for realistic art would predict support for Brexit. Data on a large nationally representative sample of the British population were obtained, and preference for realistic art was measured using a four-item binary choice test. Controlling for a range of personal characteristics, we found that respondents who preferred all four realistic paintings were 15-20 percentage points more likely to support Leave than those who preferred zero or one realistic paintings. This effect was comparable to the difference in support between those with a degree and those with no education, and was robust to controlling for the respondent's party identity.

Cognitive Control Moderates the Health Benefits of Trait Self-Regulation in Young Adults

Separate lines of epidemiological research suggest that individuals with high trait self-regulation (e.g. conscientious individuals) and individuals with higher cognitive ability (e.g. executive control/intelligence) each tend to enjoy superior health and well-being outcomes. However, it remains largely unexplored whether these personological and cognitive contributions to physical health are shared, independent, or interdependent. In the current study, we examined associations between trait self-regulation, cognitive control, self-reported physical health, and subjective well-being. A domain-general model revealed little shared variance between trait self-regulation and cognitive control but revealed significant unique relationships between each predictor and physical health. Results of a latent moderation analysis suggested that cognitive control moderated the contribution of self-regulation to health but not subjective well-being. This moderation effect was characterized by a strengthened relationship between trait self-regulation and health with decreases in cognitive control. Together, our results suggest that self-regulation and cognitive control may independently contribute to health outcomes in young adults and that self-regulation may be increasingly important for individuals lower in cognitive control.

Performance Monitoring and Correct Response Significance in Conscientious Individuals

There is sufficient evidence to believe that variations in the error-related negativity (ERN) are linked to dispositional characteristics in individuals. However, explanations of individual differences in the amplitude of the ERN cannot be derived from functional theories of the ERN. The ERN has a counterpart that occurs after correct responses (correct-response negativity, CRN). Based on the assumption that ERN and CRN reflect an identical cognitive process, variations in CRN might be associated with dispositional characteristics as well. Higher CRN amplitudes have been found to reflect task engagement. In the present study, a simple-choice-reaction task was used to investigate ERN and CRN amplitudes in relation to their score on a conscientiousness scale. The task consisted of a simple rule that required pressing the left or right key when a circle or square appeared, respectively. During alternative conditions that occur infrequently, participants were instructed to violate or reverse the previously established response rules. Smaller ΔERN amplitudes (manifested in almost equal CRN and ERN amplitudes) and a tendency of better task performance from participants scoring high on the conscientiousness scale might indicate a greater focus on the task and higher motivation of responding correctly. In addition, higher Pc amplitudes directly following the CRN indicated that the response monitoring system of less conscientious participants showed a higher disengagement. The role of individual differences in CRN amplitude should be studied in future experiments on performance monitoring.

Personality Dynamism and Academic Performance Among Boarders and Non-boarders Studying in a Medical University

Introduction The personality of a human being consists of his behavior, cognition, emotional abilities, and interaction with his surroundings. The personality of an individual is modified by his ability for social perception, life experiences, and training. The pattern of study in which a person acquires education has a great influence on their personality. Objective To compare the personality traits and academic performance of boarders and non-boarders studying in a medical university. Material and methods It is a comparative, descriptive cross-sectional study done at Rawalpindi Medical University, Pakistan. The duration of the study was from January 2019 to April 2019. A questionnaire was randomly distributed among the students of Rawalpindi Medical University and filled under supervision. The questionnaire had two parts: (1) Academic performance information and (2) Big Five inventory (BFI-40). Only MBBS students of Rawalpindi Medical University were included. For statistical analysis, the independent t-test was applied using the Windows IBM Statistical Package for the Social Sciences Version 22 (SPSS, IBM Corp., Armonk, NY, US). The statistically significant value was taken as 0.05. Results Out of 300 questionnaires distributed, 287 were properly filled, giving a response rate of 95.6%. The Cronbach's alpha value was .750. The mean age was 20.87±1.344. There were 216 (75.1%) male and 71 (24.9%) females. One-hundred eighty-three (63.8%) were boarders and 104 (36.2%) were non-boarders. The mean scores of extraversion, agreeableness, and conscientiousness were higher for boarders while the mean scores of neuroticism and openness were higher for non-boarders. High average percentages in professional exams were common in non-boarders while boarders were taking more supplementary exams comparatively. Conclusion Self-discipline, surgency from external activities/situations, and getting along with others are common traits among boarders. On the other hand, non-boarders are more creative but emotionally unstable. The academic status of boarders is comparatively poor. Thus, the hostel administration should be particularly concerned about the activities of boarders, and parents should be aware of their child's academic status. Teachers should pay special attention to the character development of students.

A Psychometric Evaluation of the Short Grit Scale: A Closer Look at its Factor Structure and Scale Functioning

Grit, the passion and perseverance for long-term goals, has received attention from personality psychologists because it predicts success and academic achievement. Grit has also been criticized as simply another measure of self-control or conscientiousness. A precise psychometric representation of grit is needed to understand how the construct is unique and how it overlaps with other constructs. Previous research suggests that the Short Grit Scale (Grit-S) has several psychometric limitations, such as uncertain factor structure within and across populations, uncertainty about reporting total or subscale scores, and different assessment precision at low and high levels on the construct. We conducted modern psychometric techniques including parallel analysis, measurement invariance, extrinsic convergent validity, and Item Response Theory models on two American samples. Our results suggest that the Grit-S is essentially unidimensional and that there is construct overlap with the self-control construct. Subscale factors were the result of an item doublet, where two items had high correlated uniquenesses, showed similar item information, and were more likely to exhibit measurement bias. Findings replicated across samples. Finally, we discuss recommendations for the use of the Grit-S based on the theoretical interpretation of the unidimensional factor and our empirical findings.

Is Grit the New Fit?-Assessing Non-Cognitive Variables in Orthopedic Surgery Trainees

OBJECTIVE

The purpose of this study was to determine overall levels of grit, self-control, and conscientiousness among orthopedic surgery residents, to compare levels of grit across orthopedic resident training levels, and to identify common applicant variables which may correlate with these valuable noncognitive attributes.

DESIGN

A cross-sectional study composed of a confidential electronic survey consisting of a 17-item Grit scale, 10-item Self-control scale, and 9-item Conscientiousness scale was completed by Orthopedic residents and fellows.

SETTING

Department of Orthopedic Surgery, Mayo Clinic, Rochester, MN; a tertiary medical center.

PARTICIPANTS

Grit, ambition, consistency of interest, perseverance of effort, self-control, and conscientiousness were assessed in orthopedic surgery residents and fellows. The survey was distributed to program coordinators of ACGME accredited Orthopedic Surgery residency programs and fellowship. 431 (431 out of 621, 69.4%) respondents completed the assessment.

RESULTS

Orthopedic residents demonstrated high baseline levels of grit (4.0 of 5.0), self-control (3.8 of 5.0), and conscientiousness (4.4 of 5.0). The grit score of 4.0 places them in the 65th percentile of the general adult population. There were no significant differences in scores between training levels of orthopedic residents and fellows. Significantly higher self-control scores were seen in female trainees (p = 0.042), inductees of Alpha Omega Alpha honor society (p = 0.008), and those with higher numbers of publications (p = 0.037). Orthopedic trainees with more publications scored higher in the ambition sub-score (0 publications: 4.0 ± 0.7; 1-3 publications: 4.2 ± 0.5, 3 or more publications: 4.3 ± 0.5; p < 0.001).

CONCLUSIONS

Orthopedic surgery residents demonstrated high levels of grit compared to the general population. Key objective variables utilized in the residency application process including Alpha Omega Alpha status and volume of research publications were predictive of these qualities.

Trait Conscientiousness predicts rate of brain atrophy in multiple sclerosis

BACKGROUND

Conscientiousness is a core personality trait with favorable prognosis in neuropsychiatric disease.

OBJECTIVE

We aimed to determine whether baseline Conscientiousness predicts future brain atrophy in multiple sclerosis (MS) after accounting for demographic and basic clinical characteristics.

METHODS

Trait Conscientiousness, clinical features, and Expanded Disability Status Scale (EDSS) were obtained at baseline. Lateral ventricle volume (LVV) was measured longitudinally. In a retrospective general linear mixed effects model, data from 424 patients were analyzed (mean 6 time-points, up to 15 years).

RESULTS/CONCLUSION

We observed significant age and Conscientiousness by time-from-baseline interactions indicating that younger age and higher Conscientiousness are associated with reduced progression of brain atrophy.

The Emergence of Group Potency and Its Implications for Team Effectiveness

Much of the previous research on the emergence of team-level constructs has overlooked their inherently dynamic nature by relying on static, cross-sectional approaches. Although theoretical arguments regarding emergent states have underscored the importance of considering time, minimal work has examined the dynamics of emergent states. In the present research, we address this limitation by investigating the dynamic nature of group potency, a crucial emergent state, over time. Theory around the "better-than-average" effect (i.e., an individual's tendency to think he/she is better than the average person) suggests that individuals may have elevated expectations of their group's early potency, but may decrease over time as team members interact gain a more realistic perspective of their group's potential. In addition, as members gain experience with each other, they will develop a shared understanding of their team's attributes. The current study used latent growth and consensus emergence modeling to examine how potency changes over time, and its relation with team effectiveness. Further, in accordance with the input-process-output framework, we investigated how group potency mediated the relations between team-level compositions of conscientiousness and extraversion and team effectiveness. We collected data at three time points throughout an engineering design course from 337 first-year engineering students that comprised 77 project teams. Results indicated that group potency decreased over time in a linear trend, and that group consensus increased over time. We also found that teams' initial potency was a significant predictor of team effectiveness, but that change in potency was not related to team effectiveness. Finally, we found that the indirect effect linking conscientiousness to effectiveness, through initial potency, was supported. Overall, the current study offers a unique understanding of the emergence of group potency, and facilitate a number theoretical and practical implications, which are discussed.
