The Relationship between Introvert and Extrovert Personality towards Students’ Academic Achievement in Primary School

This study examines the relationship between introvert and extrovert personality with the students’ academic achievement in a primary school located in Malaysia. This study uses a quantitative approach, followed by a descriptive correlation method. Two null hypotheses were formulated to guide the study. The population is 839 students, a random sampling technique was used to determine the sample size of 269 students from Year 1 and Year 2. Eysenck Personality Questionnaire-Revised (EPQ-R) was used to measure the level of extrovert and introvert personality while the Classroom Assessment Report 2022 is used to measure students’ academic achievement. The data obtained was analysed using descriptive statistics. This study found that the mean of academic achievement for extroverted students (4.1911) was higher than the introverted students’ (4.0956). The results also show that there is no significant relationship between extroverted personality and students’ academic achievement (r = - 0.085, p = 0.257) and no significant relationship between introverted personality and students’ academic achievement (r = - 0.021, p = 0.844). This study may contribute to the primary school students, educators and Malaysia’s Ministry of Education. The findings of this study give implications that age also affects the level of extrovert and introvert personality in addition to the type of assessment that will affect the academic achievement of extrovert and introvert students.

Association between personality and the risk of ischemic heart disease mortality before and after the Great East Japan Earthquake: Data from the Miyagi Cohort Study

The purpose of the present study was to investigate the association between personality and the risk of IHD mortality among Great East Japan Earthquake (GEJE) survivors, and to investigate whether personality traits affected the increase in IHD mortality observed after the GEJE. We analyzed data for 29,065 men and women in the Miyagi Cohort Study who were 40-64 years old at baseline. We divided the participants into quartiles based on scores for each of the four personality subscales (extraversion, neuroticism, psychoticism, and lie), using the Japanese version of the Eysenck Personality Questionnaire-Revised Short Form. We divided the eight years before and after the GEJE event (11 March 2011) into two period, and examined the relationship between personality traits and the risk of IHD mortality. Cox proportional hazards analysis was used to estimate the multivariate hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of IHD mortality according to each personality subscale category. In the four years before the GEJE, neuroticism was significantly associated with an increased risk of IHD mortality. Compared with the lowest category for neuroticism, the multivariate-adjusted HR (95% CI) for IHD mortality in the highest category was 2.19 (1.03-4.67) (p-trend=0.12). In contrast, no statistically significant association between neuroticism and IHD mortality was observed in the four years after the GEJE. This finding suggests that the observed increase in IHD mortality after the GEJE can be attributed to risk factors other than personality.

Predictors of Psychological Distress among Patients with Colorectal Cancer-Related Enterostomy: A Cross-sectional Study.

To identify variables that may predict psychological distress in patients with an enterostomy. Investigators recruited 77 patients with a stoma from a stoma clinic according to the inclusion criteria. Patients' psychological distress was assessed with the Distress Thermometer (DT) tool, and their personality type was determined by the Eysenck Personality Questionnaire. Researchers also collected demographic and disease-related data. Predictive values were estimated using multiple regression analyses. The mean DT score of all patients was 5.94 (SD, 1.81), and approximately 85.7% consistently suffered from psychological distress. Being unmarried and having peristomal complications were associated with higher psychological distress, whereas having a monthly income 5,000 ¥ or more was associated with lower levels of distress. Moreover, patients with a melancholic personality type tended to have higher DT scores, which could act as a strong independent predictor for psychological distress. The majority of patients with a stoma endured moderate to severe psychological distress during follow-up care. Exploring the related factors that predict the levels of psychological distress could enable clinicians to identify at-risk patients as early as possible and thus provide optimal care for improving patients' quality of life.

Resilience among women with breast cancer surviving longer than five years: The relationship with illness perception and body image.

This study aimed to investigate the correlations and identify the relationships between the resilience, perception of illness and body image of women with breast cancer in the 5-year-or-above survivorship. We used convenient sampling to recruit from an outpatient department 106 women with breast cancer. The inclusion criteria were participants aged >20 years currently in a stable condition and were able to understand the Chinese language. Those women with mental health illness were excluded. All participants completed questionnaires on the following: demographic information, revision of illness perception (IPQ-R), body image scale (BIS), Eysenck personality questionnaire (EPQ), and resilience scale (RS). We conducted the structural equation modeling (SEM) to explore the factor structure. SEM results showed a good fit to the data (comparative fit index=0.97, Tucker-Lewis index=0.94). Findings F indicated the existence of significant relationships between resilience and either illness perception or body image. Personality had a direct association with illness perception (β=0.73, P<0.05). Body image had an indirect effect on the relationship between resilience and illness perception (coefficient=-2.52; 95% bootstrapping CI=-31.36, -0.62). Results indicated that illness perception is a crucial predictor for better resilience as mediated through body image. To provide adequate information to women with breast cancer can improve their perception of breast cancer more positively. Hence, their body image and their way of coping with survival life turn better.

Personality characteristics, defense styles, borderline symptoms, and non-suicidal self-injury in first-episode major depressive disorder.

Non-suicidal self-injury (NSSI) is commonly seen in adolescents with depression and is a high-risk factor leading to suicide. The psychological mechanisms underlying depression with NSSI are still unclear. The purpose of this study was to explore the differences in personality traits, defensive styles, and borderline symptoms among first-episode youth patients with depression and self-injury compared with patients with depression without self-injury and healthy populations. The current study recruited 188 participants, including 64 patients with depression and NSSI, 60 patients with depression without NSSI, and 64 healthy control subjects. Eysenck Personality Questionnaire, the Defense Style Questionnaire, the short version of the Borderline Symptom List, the Beck Depression Inventory, and the Ottawa Self-Injury Inventory were used to assess all participants. Patients with depression and NSSI showed more psychoticism than patients with depression without NSSI and healthy control subjects. Patients with depression and NSSI presented more intermediate defense styles than healthy control subjects. In the patients with depression and NSSI group, the frequency of self-injury in the last week was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. Further regression analysis showed that EPQ-psychoticism and depressive symptoms were independent risk factors for NSSI in patients with depression. This study found that patients with depression and self-injury presented more neuroticism, introversion, EPQ-psychoticism, immature defenses, intermediate defenses, and borderline symptoms. Self-injury frequency was negatively correlated with mature defense styles and positively correlated with depressive symptoms and borderline symptoms. EPQ-Psychoticism and depressive symptoms are risk factors for predicting non-suicidal self-injury in patients with depression.

The Effect of Personality Traits of Surgical Nurses on COVID-19 Fear, Work Stress, and Psychological Resilience in the Pandemic

PurposeThis research was carried out to determine the effects of the personality traits of surgical nurses on COVID-19 fear, work stress, and psychological resilience in the pandemic. DesignThe research was descriptive and cross-sectional types. MethodsThe study was conducted between February 2021 and May 2021 at a State University Research Hospital. The research aimed to reach all surgery nurses (357) working in surgical units without selecting a sample. The sample included 325 participants. At the end of the study, the participation rate was 91.03%. Study reporting adheres to STROBE checklist. FindingsIt was determined that 43.4% of the nurses participating in the study were in the age range of 26-30, 64.9% were women. The correlation values between the COVID-19 Fear Scale and the Nurse Stress Scale scores were found to be significant in the positive direction. The correlation values between the Eysenck Personality Questionnaire neuroticism subdimension and the Nurse Stress Scale, and Fear of COVID-19 Scale scores were found to be positive. ConclusionsDuring the pandemic, it is suggested that nurses' work stress and psychological resilience levels should be evaluated at regular intervals and that in-service trainings on coping with stress and stress management should be organized. Taking the necessary precautions and improving working conditions will have positive effects on both the health of nurses and patient care.

Effect of childhood maltreatment on cognitive function and its relationship with personality development and social coping style in major depression disorder patients: A latent class model and network analysis.

The study aimed to (1) analyze the interrelationships among different types of childhood adversity, diverse personality dimensions, and individual coping style integratively among major depressive disorder (MDD) patients and healthy participants using a network approach; (2) explore the latent class of child maltreatment (CM) and its relationship with cognitive function. Data were collected from the Objective Diagnostic Markers and Personalized Intervention in MDD Patients (ODMPIM) study, including 1,629 Chinese participants. Using the Childhood Trauma Questionnaire to assess CM, the Simplified Coping Style Questionnaire to measure individual coping style, Eysenck Personality Questionnaire Revised-Short Form for personality characters, and a series of neurocognitive tests, including seven tests with 18 subtests for cognitive assessments. We used the "Network Module" in Jeffreys's Amazing Statistics Program (JASP) and R package for network analysis. A latent class analysis was performed with SAS9.4. Child maltreatment was more common in MDD patients than in healthy controls, except for emotional abuse. Network analysis showed that emotional abuse, emotional neglect, physical abuse, and physical neglect formed quadrangle connections. Personality dimensions were associated with physical neglect and emotional abuse. All types of CM (excluding sex abuse) showed an association with coping style. Emotional neglect showed the highest centrality measures. Physical neglect had a high level of closeness. To a concerning strength, emotional and physical neglect showed the highest levels. The structure of the networks is variant between groups (M = 0.28, P = 0.04). Latent class analysis (LCA) revealed that three classes provided the best fit statistics. Neglect and abuse classes tended to perform more poorly on the five cognitive domains. This study provided insights on multi-type of CM. Neglect played an important role in different routes through the relation between CM with personality traits and social coping style. However, neglect has often been ignored in previous studies and should receive more public attention.

Accelerating L1-penalized expectation maximization algorithm for latent variable selection in multidimensional two-parameter logistic models.

One of the main concerns in multidimensional item response theory (MIRT) is to detect the relationship between observed items and latent traits, which is typically addressed by the exploratory analysis and factor rotation techniques. Recently, an EM-based L1-penalized log-likelihood method (EML1) is proposed as a vital alternative to factor rotation. Based on the observed test response data, EML1 can yield a sparse and interpretable estimate of the loading matrix. However, EML1 suffers from high computational burden. In this paper, we consider the coordinate descent algorithm to optimize a new weighted log-likelihood, and consequently propose an improved EML1 (IEML1) which is more than 30 times faster than EML1. The performance of IEML1 is evaluated through simulation studies and an application on a real data set related to the Eysenck Personality Questionnaire is used to demonstrate our methodologies.

The Eysenck Personality Questionnaire Revised - Abbreviated (EPQR-A): psychometric properties of the Brazilian Portuguese version.

The Eysenck Personality Questionnaire Revised - Abbreviated (EPQR-A) consists of 24 items for assessment of the three fundamental personality traits (psychoticism, extraversion, and neuroticism) and a validity scale (lie scale). Our objectives were to assess the psychometric properties of a version of this instrument culturally adapted for Brazil. 321 participants were recruited using a non-probabilistic method. Internal consistencies ranged from minimally acceptable to respectable, except for the psychoticism domain. Higher neuroticism scores were associated with higher depression and anxiety scores, higher extraversion scores were associated with lower levels of depression symptoms, and higher psychoticism scores were associated with higher levels of depression symptoms. Our findings describe sustainable psychometric properties for the Brazilian Portuguese version of EPQR-A.

GReek Anaesthesiologists's Burnout EPidemic within the COVID-19 pandemic (GRABEP study); a multicenter study on burn out prevalence among Greek anesthesiologists and association with personality traits.

COVID-19 pandemic resulted in an unprecedented crisis with extreme distress for the frontline physicians and increased risk of developing burnout. Burnout has a negative impact on patients and physicians, posing a substantial risk in patient safety, quality of care and physicians' overall wellbeing. We evaluated burnout prevalence and possible predisposing factors among anaesthesiologists in the COVID-19 referral university/tertiary hospitals in Greece. In this multicenter, cross-sectional study we have included anaesthesiologists, involved in the care of patients with COVID-19, during the fourth peak of the pandemic (11/2021), in the 7 referral hospitals in Greece. The validated Maslach Burnout Inventory (MBI) and Eysenck Personality Questionnaire (EPQ) were used. The response rate was 98% (116/118). More than half of the respondents were females (67.83%, median age 46 years). The overall Cronbach's alpha for MBI and EPQ was 0.894 and 0.877, respectively. The majority (67.24%) of anaesthesiologists were assessed as "high risk for burnout" and 21.55% were diagnosed with burnout syndrome. Almost half participants experienced high levels of all three dimensions of burnout; high emotional exhaustion (46.09%), high depersonalization (49.57%) and high levels of low personal accomplishment (43.49%). Multivariate logistic analysis revealed that neuroticism was an independent factor predicting "high risk for burnout" as well as burnout syndrome, whereas the "Lie scale" of EPQ exhibited a protective effect against burnout. Burnout prevalence in Greek anaesthesiologists working in COVID-19 referral hospitals during the fourth peak of the pandemic was high. Neuroticism was predictive of both "high risk for burnout" and "burnout syndrome".

Gene-environment interaction study on the polygenic risk score for neuroticism, childhood adversity, and parental bonding.

The present study examines whether neuroticism is predicted by genetic vulnerability, summarized as polygenic risk score for neuroticism (PRSN), in interaction with bullying, parental bonding, and childhood adversity. Data were derived from a general population adolescent and young adult twin cohort. The final sample consisted of 202 monozygotic and 436 dizygotic twins and 319 twin pairs. The Short Eysenck Personality questionnaire was used to measure neuroticism. PRSN was trained on the results from the Genetics of Personality Consortium (GPC) and United Kingdom Biobank (UKB) cohorts, yielding two different PRSN. Multilevel mixed-effects models were used to analyze the main and interacting associations of PRSN, childhood adversity, bullying, and parental bonding style with neuroticism. We found no evidence of gene-environment correlation. PRSN thresholds of .005 and .2 were chosen, based on GPC and UKB datasets, respectively. After correction for confounders, all the individual variables were associated with the expression of neuroticism: both PRSN from GPC and UKB, childhood adversity, maternal bonding, paternal bonding, and bullying in primary school and secondary school. However, the results indicated no evidence for gene-environment interaction in this cohort. These results suggest that genetic vulnerability on the one hand and negative life events (childhood adversity and bullying) and positive life events (optimal parental bonding) on the other represent noninteracting pathways to neuroticism.

Personality Traits and Tinnitus Distress: Results Based on Patients with Tinnitus in China.

Due to the socio-cultural differences between China and other countries, which may affect the development of an individual's personality and behavior, it is necessary to explore the relationship between personality traits and tinnitus distress in the context of China's socio-cultural background. The Tinnitus Handicap Inventory and the Eysenck Personality Questionnaire Short Scale Chinese version were used to explore the influence of personality traits on tinnitus distress in Chinese patients with tinnitus. The results were not entirely consistent with previous studies from other countries. First, extroversion was significantly higher in patients with bothersome tinnitus, both in acute and chronic conditions. Second, the personality traits that affected the patients with bothersome tinnitus were different in different conditions. Finally, the tridimensional personality structure, high psychoticism / normal extroversion / normal neuroticism, was significantly higher in people with bothersome tinnitus. Furthermore, the difference became more obvious with a prolonged disease course. This study suggested that the relationship between personality traits and tinnitus distress in Chinese patients with tinnitus was not the same as in other countries. "High psychoticism / normal extroversion / normal neuroticism" may be a risk factor for chronic bothersome tinnitus in China.

ELECTROENCEPHALOGRAPHIC STUDY OF PREFRONTAL CORTEX AMONG YOUTH ATHLETES HAS GIVEN THEIR TEMPERAMENT

The problem of studies is the determination of hypothetical predictors for personality traits among five generalized EEG rhythms in the prefrontal cortex of youth soccer players. The goal of study was to explore the relationship between the oscillations of EEG rhythms in the prefrontal cortex and the personality traits of undergraduates of Sports University . The EEG was recorded using a wireless system with dry non-contact frontal sensor electrodes. The power spectrum was analyzed in five frequency bands (1-50 Hz). Personality traits determination was performed using Eysenck's personality questionnaire. A pair linear regression model, the Spearman's rank correlation and Kruskal - Wallis tests were used for analysis. The research revealed dominance of the extraversive peculiarity of the nervous system over introversive, which is likely due to preference for students, as groups as team interactions rather than individual behavioral strategies. Additionally, the findings of the study determined two slow EEG rhythms as predictors of personality traits among extraverts. It was found that delta rhythm is a correlate of extraversion, and theta rhythm is neuroticism with inversely proportional relationships. These EEG patterns of the prefrontal cortex are related to the features of behavior of youth soccer players of the extraversive type, which is caused by their temperament.

Intervention Effect of Theme Building Block Games on the Mental Health and Behavior of Children with Attention Deficit Hyperactivity Disorder.

Children with attention deficit hyperactivity disorder (ADHD) are mainly characterized by learning difficulties, emotional impulsion, excessive activity, and distracted attention, which have a certain impact on their social ability, physical and mental health, and their living ability. This study aims to explore the effects of theme building block games on the psychological behaviors of children with ADHD, and to provide some reference for promoting the mental health development of children with ADHD. A total of 180 children with ADHD in Healthcare Center for Children from January 2020 to June 2021 were selected via convenient sampling. They were randomly divided into control (n=90) and observation (n=90) groups. Children in the control and observation groups received routine and theme building block games, respectively, once a week and a total of 8 weeks of building block game interventions. Improvement of symptoms, Eysenck Personality Questionnaire (EPQ), Achenback Child Behavior Scale List (CBLC), Child Sensory Integration Development Scale, and Piers-Harris Child Self-concept Scale (PHCSS) of two groups were compared before and after intervention. After intervention, children in the two groups showed lower T scores in P and N, and higher T scores in E and L of EPQ; T scores of children in the observation group improved more significantly. Children (boys) in the two groups showed lower scores in discipline violation, hostility, compulsion, immaturity, poor communication, schizophrenia-like, and physical complaints in CBCL. Moreover, those in the observation group obtained significantly lower scores in CBCL than those in the control group. Children (girls) in the two groups showed lower scores in cruelty, aggressiveness, immaturity, depression withdrawal, schizophrenia-like, somatic complaints, and anxiety compulsion in CBCL. Meanwhile, those in the observation group obtained significantly lower scores in CBCL than those in the control group. After intervention, scores of children in the two groups in symptom improvement, sensory integration ability, and PHCSS were significantly improved. Lastly, those in the observation group obtained higher scores in these aspects compared with those in the control group. The theme building block game can effectively improve symptoms of children with ADHD and also help promote their sensory integration ability, self-concept, and personality development, as well as improve their psychological and behavioral status. Accordingly, this rehabilitation intervention method is worthy of promotion, which can be recognized and accepted easily.

Prognostic factors for persistent fatigue after COVID-19: a prospective matched cohort study in primary care.

Persistent fatigue after COVID-19 is common; however, the exact incidence and prognostic factors differ between studies. Evidence suggests that age, female sex, high body mass index, and comorbidities are risk factors for long COVID. To investigate the prevalence of persistent fatigue after COVID-19 in patients with a mild infection (managed in primary care) during the first wave of the pandemic and to determine prognostic factors for persistent fatigue. This was a prospective cohort study in Dutch general practice, combining online questionnaires with data from electronic health records. Patients who contacted their GP between March and May 2020 and were diagnosed with COVID-19 during the first wave of the pandemic were included. Patients were matched to controls without COVID-19 based on age, sex, and GP practice. Fatigue was measured at 3, 6, and 15 months, using the Checklist of Individual Strength. All the participants were GP attendees and included 179 with suspected COVID-19, but who had mild COVID and who had not been admitted to hospital with COVID, and 122 without suspected COVID-19. Persistent fatigue was present in 35% (49/142) of the suspected COVID-19 group and 13% (14/109) of the non-COVID-19 group (odds ratio 3.65; 95% confidence interval = 1.82 to 7.32). Prognostic factors for persistent fatigue included low education level, absence of a partner, high neuroticism (using the Eysenck Personality Questionnaire Revised-Short Form), low resilience, high frequency of GP contact, medication use, and threatening experiences in the past. The latter three factors appeared to be prognostic factors for persistent fatigue specifically after COVID-19 infection. GP patients with COVID-19 (who were not admitted to hospital with COVID) have a fourfold higher chance of developing persistent fatigue than GP patients who had not had COVID-19. This risk is even higher in psychosocially vulnerable patients who had COVID-19.

The Effect of Traffic Noise on Divided Attention and Perception Concerning Individual Role Differences: An Experimental Study

Background and Aim: Noise pollution is one of the urban problems that can affect the exposed individuals’ cognitive function. This study set to investigate the impact of traffic noise on drivers’ cognitive variables including perceptual capacity, speed of perception, and divided attention concerning the role of individual orientation and neuroticism. Methods: This study recruited 35 male student participants. The Eysenck personality questionnaire was used to evaluate the participants’personalities (neuroticism and extroversion). Participants were then exposed to traffic noise, and the Adaptive Tachistoscopic Traffic Perception Test (ATTPT) was performed to assess their capacity and speed of perception. The Peripheral Perception Test (PPT) was also conducted to evaluate the divided attention using the Vienna test system software. Results: Introverted and stable individuals had better performance in perceptual capacity and speed of perception tasks after exposure to traffic noise. However, these effects were not observed in extrovert and unstable individuals. This study also showed no significant alterations in variables in extroverted (introverted/extroverted) subjects with neuroticism (unstable/stable) concerning divided attention tasks after traffic noise exposure. Conclusion: This study showed that divided attention in extrovert individuals with neuroticism was not influenced by traffic noise exposure. But perceptual capacity and perception speed was influenced by traffic noise in introverts and unstable subjects. Keywords: Traffic noise; divided attention; perception; individual differences

Factors associated with the high susceptibility to depression of women during the perimenopause.

This study investigated the factors associated with the high susceptibility of perimenopausal women to depression. A total of 66 perimenopausal women participated in this study. The Zung self-rating depression scale (SDS) was used to evaluate the intensity of depressive symptoms. The modified Kupperman index (KI) was used to assess common perimenopausal symptoms. Psychosocial factors were assessed via the Eysenck Personality Questionnaire, attitudes toward menopause checklist, and metacognition questionnaire (MCQ). Levels of serum estradiol, testosterone, and progesterone were determined. There were statistically significant associations between SDS standard score and the KI scale score (β=.361, p=.001), years of education (β=-.309, p=.005), and F3 cognitive self-consciousness score of MCQ (β=-.234, p=.032; adjusted R2 =.264, F=8.759, p<.001). High susceptibility to depression of perimenopausal women may be related to lower educational level, more severe perimenopausal symptoms, and altered metacognition.

Use of Symptom Checklist 90 for exploring psychological factors among the parents of children hospitalized for burn injuries in Shanghai: a cross-sectional study

To better improve the conditions for the recovery of children with burn injuries, timely understanding of the psychological status of parents is important. A cross-sectional survey on it using convenience sampling was conducted at two hospitals. Besides basic information, the Symptom Checklist 90, Eysenck Personality Questionnaire, Social Support Rate Scale, and Simplified Coping Style Questionnaire were used, and the key factors were identified via multivariate linear regression analysis and path analysis. A total of 196 guardians were recruited, 180 valid and completed questionnaires were obtained, including 58 men (32.2%) and 122 women (67.8%), and their average age was 30.3 years (standard deviation = 7.6). Of these, 151 participants (83.9%) were parents. Multivariate analysis revealed that children’s age, parent gender, P score, negative coping style, and religion were the main factors that affected parents’ psychology. Moreover, path analysis showed that P score, children’s age, and negative coping style had the greatest impact on the total average score. These results suggest that during hospitalization, the following three factors should be focused on: older children, higher parental psychoticism, and increased negative coping style.

Effect of sound pressure levels on problem-solving abilities with the mediation of personality traits

Objective Noise can cause distraction and mental dysfunction. In examining the effects of noise, it is important to pay attention to personality traits. The aim of this study was to investigate the effect of noise exposure on problem-solving ability with the mediating role of personality type. Method This laboratory study was performed on 40 students. For this study, the recorded noise from the industry environment was broadcast to the volunteers and the students were exposed to different sound pressure levels (33, 75, 85 and 95 dBA). Eysenck Personality Questionnaire was used to assess personality type. Problem-solving abilities of students were assessed using the London Tower test. Data analysis was performed in version 22 of SPSS software. Results The results of data analysis showed that there is a significant relationship between different levels of noise pressure and students’ problem-solving ability so with increasing sound pressure level, problem-solving ability decreases (p < 0.001). No significant relationship was found between personality type and problem-solving ability (p > 0.05). Conclusion Considering the effect of noise on mental performance, noise control in work positions that require attention and processing of mental information is necessary.

Psychological Characteristics Associated with Post-Treatment Physical Status and Quality of Life in Patients with Brain Tumor Undergoing Radiotherapy

Radiotherapy (RT) is a mainstay of treatment for brain tumors. To minimize the risk of side effects while maximizing the therapeutic effects, personalized treatment plans, consisting mainly of genomics, radiomics, and mathematical modeling, are increasingly being used. We hypothesize that personality characteristics could influence treatment outcomes and thus could be used to help personalize RT. Therefore, the aim of this study was to identify the psychological characteristics associated with post-treatment physical status and quality of life (QoL) in patients with brain tumors undergoing RT. Two psychological tests-the Eysenck Personality Questionnaire and the State-Trait Anxiety Inventory-were administered prior to RT. Physical parameters before and after RT were also assessed through the following tests: hand grip strength, Timed Up and Go test, 6 Min Walk Test, and Functional Independence Measure. The Functional Assessment of Cancer Therapy-General (FACT-G) was used to assess QoL. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) was administered to assess fatigue. Neuroticism was significantly associated with low FACT-G Physical Well-Being scores. Psychoticism was associated with an improvement in physical fitness scores after RT. These findings suggest that personality traits should be considered when designing a personalized radiotherapy plan.
