Millennials of the 21st century tend to have an active daily life and practice more sports, spending more on health and fitness. Therefore, the present paper seeks to investigate the propensity of Millennials to recommend their preferred fitness center, depending on their psychological condition (i.e., introversion versus extraversion), which may lead to their tendency to practice and to their involvement and satisfaction with the fitness center. The authors deduce a conceptual model from the literature, which is further analyzed with data collected through an empirical investigation based on a face-to-face administered questionnaire. Data gathered from 2138 Millennials are investigated with the help of structural equation modeling using SmartPLS. The results show that a positive image of a fitness center stimulates the satisfaction of extravert and introvert consumers. Millennials have different personality types, such as extraversion and introversion, that influence their propensity to practice fitness and to recommend their favorite fitness center. It can be concluded that not only extraversion but also introversion influence consumers\' satisfaction, positively impacting the consumer\'s intention to recommend their favorite fitness center to peers.

Clinical communication skills training is a key element of modern medical education as it has been shown to have multiple benefits in delivering healthcare. Various factors affect clinical communication and we believe that personality is a major one. As an introverted second year medical student who has recently failed his Objectively Structured Clinical Examination (OSCE) despite passing the written knowledge examination with flying colours, I reflect on my OSCE experience and try to understand the reasons that caused my failure. Methods for improving communication skills such as role plays, systematic desensitisation and remediation are suggested. Although there is one study that has shown that introverted students score lower in OSCEs compared to extroverted students, more research is needed in this area in order to draw meaningful conclusions. Therefore, a research study is suggested to look into the correlation between personality traits and OSCE results. If a correlation is indeed found, it may suggest that medical schools should provide additional support in communication skills for introverted students.

BACKGROUND: The migration of healthcare workers is attracting growing attention worldwide. Attitudes towards emigration develop over the years, and it is possible that, in addition to social factors, they are influenced by the characteristics of a person\'s personality and the sense of belonging to the social environment. This study aimed to determine the tendencies of final-year medical students\' from Osijek, Croatia, towards emigration after graduation and after specialization, as well as their specialty preferences and to investigate whether introversion and ethnocentrism have an impact on attitudes toward leaving the country in search of employment elsewhere.
METHODS: A cross-sectional study was conducted among final-year (6th year) medical students from Osijek, Croatia, in two consecutive academic years - 2014/2015 and 2015/2016. Students completed a questionnaire about sociodemographic characteristics, academic and scientific performance, preferences about their future medical career, the medical specialty of choice, emigration tendencies after graduation and specialization, ethnocentrism and introversion.
RESULTS: There were 124 students who participated in the study (response rate: 96%). A quarter of participants agreed that they are likely or very likely to emigrate after graduation (25.0%) or after specialization (23.39%). Variables associated with the intention to emigrate were specialty preferences (students that prefer endocrinology and psychiatry had the highest emigration tendencies), academic year in which the participants were included (students included in 2014/2015 were more prone to emigrate after specialization, p = 0.060), prior involvement in scientific projects (students with experience in scientific projects expressed higher tendencies to emigrate after graduation, p = 0.023), and ethnocentrism (higher ethnocentrism was associated with a lower tendency towards emigration after specialization, Spearman\'s rho = -0.191).
CONCLUSIONS: Our finding that a quarter of final-year medical students from the Faculty of Medicine Osijek were considering emigrating from Croatia in search of employment elsewhere after graduation or specialization is not as high as in previous Croatian studies or studies conducted in other European countries. Even though these data may be encouraging, considering the lack of physicians in Croatia, interventions are needed to prevent permanent emigration to protect the future functioning of the Croatian health system. Furthermore, our study did not find significant associations between levels of introversion and ethnocentrism and tendency to emigrate from Croatia. It seems that the phenomenon covering the emigration of students is more complex and influenced by many other factors which were not included in our study.

UNASSIGNED: Extraversion and its facets of assertiveness and sociability were identified as stable predictors for leader emergence and effectiveness. However, recent research suggested that extraversion may lie in the eyes of the beholder; it might not be the leader\'s possession but their followers\' attribution of the trait that shapes these criteria of leader success.
UNASSIGNED: In our study, we reverse-engineered this relationship and assessed the effects of effective leadership behaviors on personality perceptions. More specifically, we created scenarios of a leader responding to coordination challenges with passive-avoidant, transactional, or transformational leadership behaviors. We presented 204 participants with these scenarios and assessed how extraverted, assertive, and sociable they perceived the leader to be.
UNASSIGNED: Interestingly, and not fully meeting our expectations, ascriptions of extraversion and its facets of assertiveness and sociability did not directly relate to the effectiveness of the behaviors, as the moderately effective transactional leadership style garnered the highest ascriptions of extraversion and its facets. Further, ascriptions of extraversion to the transformational behavior of intellectual stimulation were remarkably low, matched only by the laissez-faire dimension of the passive-avoidant leadership style.
UNASSIGNED: We integrate and contrast these unexpected but explainable findings with current research, discuss potential associations between introversion and empowering leadership practices and provide suggestions for future discourse, illustrating the potential of investigating the presence of an introverted leadership advantage in the workplace of tomorrow.

UNASSIGNED: We investigated whether the relationship between extroversion and mortality changed during the COVID-19 pandemic.
UNASSIGNED: Midlife Americans were surveyed in 1995-96 with mortality follow-up through December 31, 2020. We used a Cox model to estimate age-specific mortality controlling for sex, race/ethnicity, the period trend in mortality, an indicator for the pandemic period (Mar-Dec 2020), extroversion, and an interaction between extroversion and the pandemic indicator.
UNASSIGNED: Prior to the pandemic, extroversion was associated with somewhat lower mortality (HR = 0.93 per SD, 95% CI 0.88-0.97), but the relationship reversed during the pandemic. Extroversion was associated with greater pandemic-related excess mortality (HR = 1.29 per SD, 95% CI 1.002-1.67). That is, compared with persons who were more introverted, those who were highly extroverted suffered a bigger increase in mortality during the pandemic relative to pre-pandemic mortality levels.
UNASSIGNED: The slight mortality advantage enjoyed by more extroverted Americans prior to the pandemic disappeared during the first 10 months of the COVID-19 pandemic. We suspect that the mortality benefit of introversion during the pandemic is largely a result of reduced exposure to the risk of infection, but it may also derive in part from the ability of more introverted individuals to adapt more easily to reduced social interaction without engaging in self-destructive behavior (e.g., drug and alcohol abuse).

Earth\'s known supercontinents are believed to have formed in vastly different ways, with two endmembers being introversion and extroversion. The former involves the closure of the internal oceans formed during the break-up of the previous supercontinent, whereas the latter involves the closure of the previous external superocean. However, it is unclear what caused such diverging behavior of supercontinent cycles that involved first-order interaction between subducting tectonic plates and the mantle. Here we address this question through 4D geodynamic modeling using realistic tectonic set-ups. Our results show that the strength of the oceanic lithosphere plays a critical role in determining the assembly path of a supercontinent. We found that high oceanic lithospheric strength leads to introversion assembly, whereas lower strength leads to extroversion assembly. A theoretically estimated reduction in oceanic crustal thickness, and thus its strength, during Earth\'s secular cooling indicates that introversion was only possible for the Precambrian time when the oceanic lithosphere was stronger, thus predicting the assembling of the next supercontinent Amasia through the closure of the Pacific Ocean instead of the Indian-Atlantic oceans. Our work provides a new understanding of the secular evolution of plate tectonics and geodynamics as the Earth cooled.

COVID-19 social distancing mandates increased social isolation, resulting in changes in pain severity and interference among individuals with chronic pain. Differences in personality (e.g., introversion/extraversion) may modulate responses to social isolation. We examined the influence of introversion on reported social distancing-related increases in pain interference and assessed for mediators of this relationship. Individuals with chronic pain (n = 150) completed validated questionnaires 4-8 weeks after implementation of social distancing mandates. Introversion/extraversion was measured using a subscale of the Myers-Briggs Type Indicator and changes in pain and psychosocial variables were calculated by comparing participants\' recalled and current scores. Association between introversion/extraversion and other variables were assessed using linear regression. A parallel mediation was used to examine mediators of the association between introversion and change in pain interference. Higher introversion was associated with a decrease in pain interference after social distancing (Rho = - .194, p = .017). Parallel mediation analysis revealed that the relationship between introversion/extraversion and change in pain interference was mediated by changes in sleep disturbance and depression, such that higher introversion was associated with less isolation-induced sleep disruption and depression, and thereby less worsening of pain interference. These findings suggest that personality factors such as introversion/extraversion should be considered when personalizing treatment of chronic pain.

There is reason to believe that introversion may relate to different patterns of negative and positive experiences in everyday life (\"hassles\" and \"uplifts\"), but there is little evidence for this based on reports made in daily life as events occur. We thus extend the literature by using data from ecological momentary assessments to examine whether introversion is associated with either the frequency or intensity of hassles and uplifts.
Participants (N = 242) were community-dwelling adults (63% Black, 24% Hispanic; ages 25-65; 65% women) who completed baseline measures of personality and mental health, followed by reports of hassles and uplifts 5x/day for 14 days. We present associations between introversion and hassles/uplifts both with and without controlling for mood-related factors (neuroticism, recent symptoms of depression, and anxiety).
Introversion was associated with reporting less frequent and less enjoyable uplifts, but not with overall hassle frequency or unpleasantness; exploratory analyses suggest associations with specific types of hassles.
Our results expand understanding of the role of introversion in everyday experiences, suggesting an overall association between introversion and uplifts (but not hassles, broadly) in daily life. Better understanding of such connections may inform future research to determine mechanisms by which introversion relates to health.

This study examined the relationship between origami performance, personality traits, and spatial ability. The researchers asked 43 Japanese university students (19 women and 24 men) to fold three models of origami (paper folding). Their performance was assessed by the number of successes in correctly folding the paper to make the models. They also answered the personality inventory NEO-FFI and completed the block-design test of the Wechsler Adult Intelligence Scale IV, which measures the spatial ability of people. The results showed that although origami performance demonstrated no significant relation with neuroticism, openness to experience, agreeableness, or conscientiousness, it improved as introversion tendency and spatial ability increased. There were no differences based on sex in origami performance. The findings suggest that performing origami requires spatial ability, which supports the view that origami is a potential educational material for training and enhancing spatial ability, and that introversion is advantageous to origami performance.

BACKGROUND: The main treatment methods for cancer include surgery, radiotherapy, chemotherapy, targeted drug therapy and so on. Patients often feel anger, anxiety, depression, and other negative psychological reactions in the process of treatment.
OBJECTIVE: To explore the effects of cognitive behavioral therapy on the personality characteristics of cancer patients.
METHODS: According to the matching design requirements, 150 cancer patients were divided into 3 groups based on sex, age, condition, and cultural background. Patients in the control group received conventional treatment. Patients in experimental group 1 received an intervention based on conventional treatment combined with cognitive behavioral therapy. Patients in experimental group 2 received family members\' participation in addition to the treatment given in experimental group 1. An Eysenck personality questionnaire was used to investigate all the patients before and after the intervention, and the scores for psychosis, introversion, neuroticism, and concealment degree were analyzed.
RESULTS: Compared with the control group, for experimental group 1 and experimental group 2 before and after the intervention, the four dimensions of mental quality, neuroticism, introversion and concealment degree all decreased, and the difference was statistically significant (P < 0.05). After the intervention, there were no obvious or statistically significant differences (P > 0.05) among the control group, experimental group 1, and experimental group 2 for two personality traits, psychoticism and neuroticism, both inside and outside degree and all four dimensions.
CONCLUSIONS: Simple cognitive behavioral therapy could not change the personality characteristics of cancer patients quickly, but the patients\' personality characteristics were significantly improved after treatment.
