Differential Behavioral Pathways Linking Personality to Leadership Emergence and Effectiveness in Groups

This study integrates leadership process models with process models of personality and behavioral personality science to examine the behavioral-perceptual pathways that explain interpersonal personality traits' divergent relation to group leadership evaluations. We applied data from an online group interaction study (N = 364) alternately assigning participants as leaders conducting brief tasks. We used four variable types to build the pathways in multiple mediator models: (a) Self-reported personality traits, (b) video recordings of expressed interpersonal behaviors coded by 6 trained raters, (c) interpersonal impressions, and (d) mutual evaluations of leadership emergence/effectiveness. We find interpersonal big five traits to differently relate to the two leadership outcomes via the behavioral-perceptual pathways: Extraversion was more important to leadership emergence due to impressions of assertiveness evoked by task-focused behavior being strongly valued. Agreeableness/emotional stability were more important to leadership effectiveness due to impressions of trustworthiness/calmness evoked by member-focused/calm behavior being stronger valued.

The impact of intimate partner violence on depressive symptoms among college students: A moderated mediation model of the big five personality traits and perceived social support

BACKGROUND

Previous study has identified a connection between intimate partner violence (IPV) and depressive symptoms. However, the underlying mechanisms of this connection have not yet been well understood. The aim of this study was to investigate the roles of big five personality traits and perceived social support on the association between IPV and depressive symptoms among Chinese college students.

METHODS

A cross-sectional questionnaire survey was conducted among college students in 23 provinces, 5 autonomous regions, and 4 municipalities in China from June to August 2022. Intimate Partner Violence Questionnaire was used to measure the frequency of exposure to IPV. The big five personality traits were measured by 10-item Big Five Inventory, Perceptive Social Support Scale-3 items was used to estimate the degree of perceived social support and the data on depressive symptoms were collected by Patient Health Questionnaire-9 items. We used data from the "Psychology and Behavior Investigation of Chinese Residents in 2022", which includes 6686 valid questionnaires of college students. The PROCESS macro developed by Hayes was utilized to perform moderated mediation analysis.

RESULTS

Among college students, IPV had a significant direct impact on depressive symptoms. Extroversion, agreeableness, conscientiousness and neuroticism mediated the association between IPV and depressive symptoms (β = -0.08, P < 0.001; β = -0.08, P < 0.001; β = -0.14, P < 0.001; β = 0.20, P < 0.001). Perceived social support significantly moderated the mediating role of the big five personality traits between IPV and depressive symptoms. Furthermore, perceived social support moderated the direct relationship between IPV and depressive symptoms (β = 0.34, P < 0.001), as well as the indirect path of extroversion, agreeableness, neuroticism and the first half of the mediating role of conscientiousness. Moreover, perceived social support was one of the preventive factors that could effectively mitigate the harmful effects of IPV, neuroticism and depressive symptoms.

LIMITATIONS

As this was a cross-sectional study, we were unable to investigate causal relationships between variables. The prevalence of IPV and depressive symptoms were self-reported by the college students, and there may be reporting bias. Additionally, this study only explored the influence and mechanism from the integrated dimension of IPV and PSSS, due to spatial constraints.

CONCLUSIONS

The findings contribute to the existing understanding by clarifying the fundamental mechanisms linking IPV and depressive symptoms. These results may serve as a valuable reference for the Chinese government to improve mental health among college students.

The effects of big five personality traits on sub-health in a Chinese young adults: A moderated mediation model

BACKGROUND

Sub-health can have an impact on the physical condition of the youth adults, and this study aimed to investigate the influencing factors of sub-health related to the Big Five personality in the Chinese youth adults.

METHODS

A multi-stage random sampling method was used to survey young adults. A moderated mediation analysis was conducted to investigate how overall sleep quality and family health influenced the relationship between youth with different personalities and sub-health.

RESULTS

A total of 6165 young adults were included in this study. The results of the mediation analyses indicated that sleep quality partially mediated the relationship between neurotic, extraversion, agreeableness, and conscientiousness of young adults and sub-health. Family health played a moderating role in the sleep quality of agreeableness young adults.

LIMITATIONS

The cross-sectional study limits conclusions about causal relationships between factors.

CONCLUSION

Family health and sleep quality can influence sub-health in the Chinese youth adults with different personality traits.

The mediating effect of perceived stress on the relationship between big five personality traits and suboptimal health status in Chinese population: a nationwide survey in the framework of predictive, preventive, and personalized medicine

Background

The effects of psychological factors on suboptimal health status (SHS) have been widely described; however, mechanisms behind the complex relationships among the Big Five personality traits and SHS are unclear. Identifying people with specific traits who are susceptible to SHS will help improve life quality and reduce the chronic disease burden under the framework of predictive, preventive, and personalized medicine (PPPM / 3PM). This study investigated the relationships among personality traits and SHS. It also explored whether perceived stress plays a mediating role in SHS development.

Method

A nationwide cross-sectional survey based on multistage random sampling was conducted in 148 cities in China between June 20 and August 31, 2022. Personality traits, perceived stress, and SHS were evaluated using the Big Five Inventory-10 (BFI-10), the 4-item Perceived Stress Scale (PSS-4), and the Short-Form Suboptimal Health Status Questionnaire (SHSQ-SF), respectively. Pearson's correlation analysis was employed to examine the associations between personality traits, perceived stress, and SHS. Structural equation modeling (SEM) was used to discern the mediating role of perceived stress in the relationships among personality traits and SHS.

Result

A total of 22,897 participants were enrolled in this study, among whom the prevalence of SHS was 52.9%. SHS was negatively correlated with three trait dimensions (i.e., extraversion, agreeableness, and conscientiousness) but positively correlated with neuroticism. Meanwhile, stress was negatively correlated with extraversion, agreeableness, conscientiousness, and openness, whereas it was positively correlated with neuroticism. The SEM results showed that, when adjusting for covariates (i.e., gender, age, BMI, educational level, current residence, marital status, and occupational status), higher agreeableness (β =  - 0.049, P < 0.001) and conscientiousness (β =  - 0.103, P < 0.001) led to lower SHS prevalence, higher neuroticism (β = 0.130, P < 0.001), and openness (β = 0.026, P < 0.001) caused SHS to be more prevalent. Perceived stress played a partial mediating role in the relationships among personality traits and SHS, respectively, contributing 41.3%, 35.9%, and 32.5% to the total effects of agreeableness, conscientiousness, and neuroticism on SHS. Additionally, the mediating impact of stress was significant even though extraversion had no direct effect on SHS.

Conclusion

This study revealed a high prevalence of SHS in Chinese residents. Personality traits significantly influenced SHS rates, which perceived stress tended to mediate. From a PPPM perspective, early screening and targeted intervention for people with neuroticism (as well as stress alleviation) might contribute to health enhancement and chronic disease prevention.

A network analysis bridging the gap between the big five personality traits and burnout among medical staff

BACKGROUND

Burnout is a common issue among medical professionals, and one of the well-studied predisposing factors is the Big Five personality traits. However, no studies have explored the relationships between these traits and burnout from a trait-to-component perspective. To understand the specific connections between each Big Five trait and burnout components, as well as the bridging effects of each trait on burnout, we employed network analysis.

METHODS

A cluster sampling method was used to select a total of 420 Chinese medical personnel. The 15-item Chinese Big Five Personality Inventory-15 (CBF-PI-15) assessed the Big Five personality traits, while the 15-item Maslach Burnout Inventory-General Survey (MBI-GS) assessed burnout components. Network analysis was used to estimate network structure of Big Five personality traits and burnout components and calculate the bridge expected influence.

RESULTS

The study revealed distinct and clear relationships between the Big Five personality traits and burnout components. For instance, Neuroticism was positively related to Doubt significance and Worthwhile, while Conscientiousness was negatively related to Accomplish all tasks. Among the Big Five traits, Neuroticism displayed the highest positive bridge expected influence, while Conscientiousness displayed the highest negative bridge expected influence.

CONCLUSIONS

The network model provides a means to investigate the connections between the Big Five personality traits and burnout components among medical professionals. This study offers new avenues for thought and potential targets for burnout prevention and treatment in medical personnel, which can be further explored and tested in clinical settings.

The mediating role of big five traits and self-efficacy on the relationship between entrepreneurship education and entrepreneurial behavior: Study of Tunisian university graduate employees

The present paper aimed to explore the mediating roles of entrepreneurial self-efficacy and the big five personality traits in the relationship between entrepreneurship education and university graduate employees' entrepreneurial behavior. Structural equations modeling was applied to data collected through a survey questionnaire among 300 Tunisian employees with a university degree working in the private sector who participated in 2021 in an entrepreneurship education program provided by the Sfax Business Center, a Public-Private organization. The results demonstrate that entrepreneurship education, entrepreneurial self-efficacy, and the big five personality traits affect entrepreneurial behavior positively. Moreover, entrepreneurship education has a positive effect on self-efficacy and the big five personality traits. The findings also show a significant partial mediation of self-efficacy and the big five personality traits on the relationships between entrepreneurship education and entrepreneurial behavior.

How to effectively communicate health information on social media depending on the audience's personality traits: An experimental study in the context of organ donation in Germany

OBJECTIVE

The shortage of organs donated for transplantation is a global concern. Even though increasing awareness can boost organ donation registration rates (thus leading to a higher number of available organ transplants), public organ donation campaigns lack effectiveness and are rarely tailored to audiences. To further enhance the effectiveness of digital health (i.e., organ donation) communication, we assessed the perception of social media organ donation campaign strategies (i.e., transformational, informational, neutral) as a function of personality traits (i.e., Big Five).

METHOD

Data was collected through an online experiment with 1000 participants (i.e., German citizens between 18 and 70 years) who were recruited via Facebook and Prolific between Jun-Aug 2022. Perceived message effectiveness of the organ donation posts was measured on a 5-point Likert scale applying the AIDA model and consequently analyzed using multiple regression analyses.

RESULTS

Messaging strategy applied in the social media campaigns served as a predictor for message effectiveness depending on the personality traits of the audience when controlling for demographics and donor status. Extraversion was positively associated with higher message effectiveness of the transformational post while neuroticism showed a significant positive association with informational content. Agreeableness was positively correlated with transformational as well as informational post effectiveness. Furthermore, higher perceived post effectiveness increased the likelihood to sign-up for further organ donation information.

CONCLUSION

Our results show that Instagram in Germany is an underleveraged but potentially effective platform to spread organ donation knowledge. Based on our results, we urge public health authorities to revisit and start tailoring their (digital) health (i.e., organ donation) campaigns to audiences (i.e., personality traits) to increase their effectiveness.

Association of personality traits with dental visit procrastination by Japanese university students

BACKGROUND

Procrastination is a psychological trait that causes individuals to put off doing things that need to be done. It has recently shown to result in the worsening of symptoms due to delays in seeking medical care. However, it is not clear how perception of dental disease influences dental visits. This study examined the associations of procrastination and personality traits with delayed dental visits for both acute and chronic conditions.

METHODS

Of 599 university students queried, the data of 549 subjects (mean age 19.7 years) were analyzed. A general procrastination scale (GPS), the Big Five personality traits, and oral hygiene habits were used for analysis. The participants were asked about illness awareness conditions related to dental disease, perception of pain in the oral region due to acute oral symptoms and chronic symptoms. The participants were asked the number of days until they decided that treatment was required. Based on the bimodal shape of the distribution, those who answered at least eight days for acute or chronic conditions were classified as the procrastination (P) group and the others as the non-procrastination (Non-P) group.

RESULTS

Significant differences in GPS scores were found between the groups for both acute and chronic conditions, with significant differences in the Big Five traits of extraversion, agreeableness, and neuroticism for an acute condition and extraversion, openness, and neuroticism for a chronic condition. There were no significant differences regarding oral hygiene habits between the groups for either condition. Next, using a Bayesian network, the probabilistic causal relations among procrastination, the Big Five traits, and delays in dental visits for both acute and chronic conditions were analyzed. Among the Big Five traits, conscientiousness and neuroticism were directly related to GPS score. Interestingly, agreeableness was directly related to delays in dental visits only for an acute condition and showed a negative effect, while dental student status had a positive effect on delays in dental visits.

CONCLUSIONS

The results showed that procrastination and dentistry department are factors that directly influence delays in dental visits, while agreeableness, a Big Five trait, has a negative effect on individuals with an acute condition.

Get creative to get ahead? How personality contributes to creative performance and perceptions by supervisors at work

What are creative employees like, aside from being high on Openness to Experience? Based on a sample of 170 full-time working professionals in the consulting industry, the present study investigated the Big Five personality predictors of both supervisory perceptions and performance ratings of creative individuals at work. Results suggested that those with higher Openness and Extraversion but lower Agreeableness, were more likely to be perceived as creative people by their supervisors. In terms of their actual creative performance on the job, employees with higher Openness, Extraversion, and Conscientiousness, received better supervisory ratings. In highlighting the impact of other Big Five traits in addition to Openness, we interpreted the findings in terms of motives to get ahead or get along and further discussed the implications of the study results for personality and creativity research in the workplace.

Exploring the surgical personality

Surgery is a demanding field, requiring determination and emotional stability. This review explores the surgical personality, addressing international personality differences between surgical and non-surgical specialties. Across the globe, surgically-interested individuals (i.e., medical students, residents, surgeons) generally scored higher on conscientiousness, open mindedness, and extraversion, and lower on neuroticism compared to non-surgically-interested contemporaries. Extraversion was inversely correlated to burnout in surgical residents and open mindedness to reduced competence in giving feedback. Although additional region- and/or country-specific research is warranted, being or becoming a surgeon appears to correlate to personality traits such as high conscientiousness and low neuroticism.

The relationship between the big five personality traits and job satisfaction with virtual teaching among teachers of students with learning difficulties

BACKGROUND

Job satisfaction has been described to be an important for individuals as well as for the society in general. However, several factors were introduced to be crucial for job satisfaction; one of the more influenced factors in satisfaction experiences is individual personality. The present study aim is to identify the relationship between the five major traits of personality and job satisfaction with virtual education among teachers of students with learning difficulties.

MATERIALS AND METHODS

The research is a descriptive quantitative design. The research population consists of 94 male and female teachers who are involved in primary and intermediate public schools in Saudi Arabia. Data were then exposed to the analysis, namely, descriptive statistics, Pearson correlation, and Mann-Whitney U test to obtain the answers to the research questions at the level of <0.05.

RESULTS

Based on the results, the most common personality trait among the study sample is conscientiousness, while neuroticism was the least common among the five traits. It was also found that there are differences between males and females in all dimensions of job satisfaction with virtual education (satisfaction with the nature of work - the relationship with colleagues and bosses - the relationship with parents) and the overall score in favor of females, except for the dimension of the relationship with colleagues and superiors, where males and females are equal.

CONCLUSION

The average score of the personality types and job satisfaction is moderate. Job satisfaction has a significant relationship with personality types. In addition, partial significant differences were found among the study variables. Given the importance of identifying teachers' personality in the workplace, reducing psychological and work factors effects in the educational environment among teachers can be helpful to enhance their job satisfaction. The study therefor, enumerated implications and recommendations based on the findings.

Factor structure of ten psychoactive substance addictions and behavioural addictions

Over the past two decades, many problematic/excessive behaviours have increasingly been conceptualized as addictions due to their similarity with more traditional psychoactive substance addictions. The primary aim of the present study was to simultaneously examine the factor structure of three psychoactive substance addictions (alcohol use, cigarette smoking, and substance use) and seven behavioural addictions (sex, social media use, shopping, exercise, online gambling, internet gaming, and internet use), using exploratory factor analysis (EFA; N = 481) and confirmatory factor analysis (CFA; N = 487). A total of 968 participants completed an online survey including ten psychometric scales assessing the ten different potentially addictive behaviours. EFA supported a two-factor solution, with different factors for the psychoactive substance and behavioural addictions (excluding exercise addiction). CFA supported the two-factor model in a separate sample. There was good support for the concurrent and discriminant validities of the CFA latent factors and the reliability of the behavioural latent factor in the two-factor CFA model. While there was support for the concurrent and discriminant validities of the psychoactive substance latent factor, there was insufficient support for its reliability. The taxonomic, theoretical, and clinical implications of the findings are discussed.

Role of personality traits in collaborative group works at flipped classrooms

The Flipped Classroom (FC) approach is an important model for individualizing teaching, improving motivation, interaction, and increasing academic performance in a student-centered learning environment. However, at FC, not all students benefit equally from teaching opportunities. There may be important individual differences that affect their academic performance. The relationship between personality traits and academic performance in the FC model in which collaborative group studies are carried out is important for the design of individualized learning environments. In this context, the aim of this study is to research the relationship between academic success and personality traits within a collaborative flipped classroom model. Additionally, in this study, the differentiation of the relationship between academic success and personality traits according to gender, motivation, engagement, and interaction variables were examined. In this research, relational screening model was utilized. The application was achieved through the participation of 167 students for a 14-week period in Turkey. In the research, self-description form and data collection instruments were utilized. At the end of this research, Extraversion from personality traits is the strongest predictor of academic performance in FC. According to descriptive statistics, it was found that female students scored higher in FC settings for extraversion, and male students had higher scores for openness than other structures. In addition, it was found that the motivation scores of women and engagement scores of men were prominent. It was observed that the openness personality of the students with low motivation and the agreeableness of the students with high motivation is more dominant than the other personality structures. Students with the low level of engagement had the highest openness, and those with high agreeableness scores were the highest. The students with the low level of interaction had the highest openness scores, while those with high levels of interaction had the highest conscientiousness. While personality traits and academic achievements of students differed significantly according to gender, motivation and interaction levels, no significant difference was found according to engagement levels. The results reached in this study will guide the applicators about how the students become more ready to learn based on the personality traits of the classroom in which the FC model was utilized.

The Psychology of COVID-19 Economic Impact Payment Use

This study investigates how American adults' personality and financial self-efficacy (FSE) beliefs contributed to how they used their COVID-19 CARES Act Economic Impact Payment (EIP) for spending needs, spending wants, and financial transactions (save, invest, debt repayment). The results from a sample of 1172 Amazon MTurk users collected in July 2020 suggest that both personality traits and FSE beliefs were associated with EIP use. Specifically, this study finds that FSE and conscientiousness emerged as the most robust predictors of EIP use across all categories of financial behavior with a greater allocation of EIP funds to saving and less to spending needs and debt repayment. Additionally, greater FSE is associated with investing, while greater conscientiousness is connected to more spending on wants. The results suggest that saving habits associated with personality and FSE persist in a crisis environment, and pre-crisis preparedness may allow for greater spending flexibility on wants. Significant relationships were also found for openness, extraversion, agreeableness, and neuroticism. The findings highlight how people use unexpected financial windfalls during crises and uncertainty and how personal characteristics contribute to this decision making.

Self-reported well-being and the importance of green spaces - A comparison of garden owners and non-garden owners in times of COVID-19

This study focuses on the effects of the use of green spaces on the self-reported well-being measures of life satisfaction and mental well-being during the COVID-19 pandemic. We compare two distinct groups of people: garden owners and non-garden owners. We collected quantitative data and data from an open-ended question online from 495 people living in all regions of Germany in May 2020. To analyze our quantitative data, we used a combination of descriptive statistics and hierarchal regressions. Here, results indicated that garden owners had substantially greater life satisfaction and mental well-being than non-garden owners. Additionally, the two groups differed statistically significant in many socioeconomic factors (e.g., income, age, fear of job loss), in the context of time spent outside, as well as personality traits. Our analyses suggest that these differences are valuable for understanding differences between the two groups' self-reported well-being. To analyze the open-ended question, we followed the main steps of a qualitative content analysis. Here, we found that the vast majority of participants associated positive meanings (e.g., freedom and joy) with private gardens and public green spaces during the pandemic. Our findings have implications for policies to promote and support the design and use of public green spaces. Overall, our findings support governmental decisions in Germany (as elsewhere) to keep public green spaces open during the first wave of the outbreak of COVID-19, suggesting that green spaces provide valuable support for self-reported well-being in these difficult times of COVID-19 contagion.

Individual differences in functional food consumption: The role of time perspective and the Big Five personality traits

Prior research suggests inconsistent relationships between individuals' personality traits, time perspective, and specific behavior. In a large representative sample of Norwegian consumers (N = 810), we investigated the relationships between the Big Five personality traits, domain-specific consideration of future consequences (CFC), and consumption of functional foods. Structural equation modeling was employed to test the hypothesized associations. Both CFC-Future and CFC-Immediate were positively related to the consumption of functional foods, whereas personality traits exerted no direct influence on consumption. Several significant associations between personality traits and CFC-Future and CFC-Immediate were found, and three of the five personality traits-Conscientiousness, Agreeableness, and Neuroticism-exerted indirect effects on consumption frequency via CFC-Future. Results support an integrative and hierarchical understanding of how personality traits and time perspective interact in explaining variation in functional food consumption. The findings support the notion that (domain-specific) CFC is better conceptualized as two distinct-albeit related constructs-that are shaped, in part, by broader personality traits.

The effects of personality and locus of control on trust in humans versus artificial intelligence

Introduction

We are increasingly exposed to applications that embed some sort of artificial intelligence (AI) algorithm, and there is a general belief that people trust any AI-based product or service without question. This study investigated the effect of personality characteristics (Big Five Inventory (BFI) traits and locus of control (LOC)) on trust behaviour, and the extent to which people trust the advice from an AI-based algorithm, more than humans, in a decision-making card game.

Method

One hundred and seventy-one adult volunteers decided whether the final covered card, in a five-card sequence over ten trials, had a higher/lower number than the second-to-last card. They either received no suggestion (control), recommendations from what they were told were previous participants (humans), or an AI-based algorithm (AI). Trust behaviour was measured as response time and concordance (number of participants' responses that were the same as the suggestion), and trust beliefs were measured as self-reported trust ratings.

Results

It was found that LOC influences trust concordance and trust ratings, which are correlated. In particular, LOC negatively predicted beyond the BFI dimensions trust concordance. As LOC levels increased, people were less likely to follow suggestions from both humans or AI. Neuroticism negatively predicted trust ratings. Openness predicted reaction time, but only for suggestions from previous participants. However, people chose the AI suggestions more than those from humans, and self-reported that they believed such recommendations more.

Conclusions

The results indicate that LOC accounts for a significant variance for trust concordance and trust ratings, predicting beyond BFI traits, and affects the way people select whom they trust whether humans or AI. These findings also support the AI-based algorithm appreciation.

Depressive symptomatology and personality traits in patients with symptomatic and asymptomatic peripheral arterial disease

Background

The aim of this study was to examine the relationship of depressive symptomatology and personality traits with peripheral arterial disease (PAD).

Methods

The sample of this cross-sectional study comprised of 300 individuals (M_age = 65.3 ± 8.7 years, 61.0% female) recruited from the offices of 33 general practitioners. Based on at-rest ankle-brachial index (ABI) values and claudication symptoms, four subsamples were formed: clear PAD-positive, clear PAD-negative, ABI-negative but symptomatic, and a non-compressible-artery group. The concurrent role of depression (assessed by a shortened version of the Beck Depression Inventory) and personality traits (measured by the Big Five Inventory) in predicting PAD status was examined using multinomial logistic regression – controlled for sex, age, hypertonia, diabetes, smoking, hazardous drinking, and body mass index.

Results

Depressive symptomatology was significant in predicting peripheral arterial disease status even after controlling for both traditional risk factors and personality traits. Among the Big Five personality traits, neuroticism showed a significant, positive relationship with PAD – independently of depression.

Conclusions

Patients with PAD – even those with asymptomatic forms of the disease – are at higher risk for suffering from depression compared to individuals without PAD, independently of neuroticism, other Big Five personality dimensions or traditional risk factors for cardiovascular diseases.

Facebook addiction and personality

This study explored the associations between Facebook addiction and personality factors. A total of 114 participants (age range of participants is 18-30 and males were 68.4% and females were 31.6 %) have participated through an online survey. The results showed that 14.91 % of the participants had reached the critical polythetic cutoff score, and 1.75 % has reached the monothetic cutoff score. The personality traits, such as extraversion, openness to experience, neuroticism, agreeableness, conscientiousness, and narcissism, are not related to Facebook addiction and Facebook intensity. Loneliness was positively related to Facebook addiction, and it significantly predicted Facebook addiction by accounting to 14% of the variation in Facebook addiction. The limitations and suggestions for further research have been discussed.

Improvement of mindfulness skills during Mindfulness-Based Cognitive Therapy predicts long-term reductions of neuroticism in persons with recurrent depression in remission

BACKGROUND

This study examined whether changes in mindfulness skills following Mindfulness-based Cognitive Therapy (MBCT) are predictive of long-term changes in personality traits.

METHODS

Using data from the MOMENT study, we included 278 participants with recurrent depression in remission allocated to Mindfulness-Based Cognitive Therapy (MBCT). Mindfulness skills were measured with the FFMQ at baseline, after treatment and at 15-month follow-up and personality traits with the NEO-PI-R at baseline and follow-up.

RESULTS

For 138 participants, complete repeated assessments of mindfulness and personality traits were available. Following MBCT participants manifested significant improvement of mindfulness skills. Moreover, at 15-month follow-up participants showed significantly lower levels of neuroticism and higher levels of conscientiousness. Large improvements in mindfulness skills after treatment predicted the long-term changes in neuroticism but not in conscientiousness, while controlling for use of maintenance antidepressant medication, baseline depression severity and change in depression severity during follow-up (IDS-C). In particular improvements in the facets of acting with awareness predicted lower levels of neuroticism. Sensitivity analyses with multiple data imputation yielded similar results.

LIMITATIONS

Uncontrolled clinical study with substantial attrition based on data of two randomized controlled trials.

CONCLUSIONS

The design of the present study precludes to establish whether there is any causal association between changes in mindfulness and subsequent changes in neuroticism. MBCT could be a viable intervention to directly target one of the most important risk factors for onset and maintenance of recurrent depression and other mental disorders, i.e. neuroticism.
