Use of default option nudge and individual differences in everyday life decisions.

People often make inefficient decisions for themselves and the community (e.g. they underuse medical screenings or vaccines and they do not vote) also because of their individual characteristics, such as their level of avoidance or anxiety. In recent years, governments have successfully applied strategies, called "nudges", to help people maximizing their decisions in several fields; however, the role of individual characteristics has been poorly explored. The present study investigated whether one kind of nudge, the default option (automatic enrolment in a specific plan), can modulate the influence of such individual differences, promoting favourable decisions in different field, such as the medical and civic ones. One hundred and eighty-three participants completed the Trait Anxiety Inventory, the General Decision-Making Styles Inventory and scenarios about health and civic decisions. Participants have hypothetically been enrolled by default or not enrolled in specific plans and had to decide whether adhere or not to the plan proposed. Result showed that the default option drives anxious and avoidant individuals, who usually refuse to make a choice due to their overestimation of negative events' occurrence, to undergo medical screenings and vaccine and to vote more. Nudge confirmed its effectiveness in favouring better decisions among people according to their individual differences.

Association between personality characteristics and sleep quality among Chinese middle-aged and older adults: evidence from China family panel studies.

BACKGROUND: Poor sleep quality will have adverse effects on physical and mental health, quality of life and other aspects of middle-aged and older adults. Sleep quality is affected by many factors. Whether the sleep quality measures of the participants had changed in the previous or subsequent time period is not easily taken into account. Moreover, there have been no studies on this topic in Chinese middle-aged and older adults. The objective of this study was to mitigate the bias of sleep quality assessment, and analyze the association between personality traits and sleep quality in Chinese middle-aged and older adults. METHODS: The data came from the China Family Panel Studies (CFPS). A total of 6031 participants aged ≥ 45 years were included in this study. Personality characteristics were evaluated based on the scores of each dimension of Big Five personality traits. Sleep duration and sleep perception were used as indicators to measure sleep quality. Logistic models were used to analyze the relationship between personality traits and sleep duration or sleep perception, respectively. RESULTS: 4.5% of the participants had abnormal sleep duration, and 14.4% had a pessimistic sleep perception. Conscientiousness was rated the highest among the personality traits (3.97 ± 0.6). Participants with higher scores for extraversion personality traits had more normal sleep duration (OR = 0.77, 95% CI: 0.64-0.93) and more optimistic sleep perception (OR = 0.86, 95% CI: 0.76-0.96). Using the Internet and feeling unwell in the past week have a moderating effect on the impact of conscientiousness personality characteristics on sleep duration or sleep perception, respectively (but not overall sleep quality). In addition, participants with a spouse or no recent physical discomfort tended to have a normal sleep duration and a more optimistic sleep perception. CONCLUSIONS: The higher the score of extraversion personality traits, the better the overall sleep quality of middle-aged and older adults. Having a spouse and feeling unwell were the important factors affecting their sleep quality. Specific personality traits intervention should be carried out for middle-aged and older adults with poor sleep quality to make their personality traits are closer to extraversion. In addition, middle-aged and older adults without spouses should be encouraged to marry or remarry. We will strengthen health management and medical expenditures for middle-aged and older adults.

Personality and demographic characteristics of parents who occasionally use psychoactive substances.

Although parenting is considered a turning point that reduces non-normative behaviours, some parents choose to occasionally continue using various drugs. The present study examines the personality and demographic characteristics of these parents by comparing three parent groups: those who do not use at all, those who use only cannabis and those who use other substances. Three self-report quantitative questionnaires: Demographic, Patterns of use of psychoactive substances and the Big Five Personality traits questionnaire, were administered to 627 parents. The findings show that the proportion of unmarried and secular men is higher in the group of parents who use substances. They also were found to be younger and less educated than the other parent's groups. We examined the parents' personality characteristics using the Big Five model and found that parents who use substances occasionally exhibit higher levels of extraversion and openness to experiences, and lower levels of conscience. The differences found in the characteristics of parents who use cannabis to those who use other substances, indicate the normativeness of cannabis use among parents, and reflect the need for intervention programs among parents who use substances, which may have a great influence on drug use among their children.

THE QUALITY OF LIFE FOR STUDENTS IN EDUCATIONAL INSTITUTIONS: CURRENT SITUATIONS AND BASIC PRINCIPLES OF PSYCHOHYGIENIC IMPROVEMENT.

OBJECTIVE: The aim: To develop the key principles of psychohygienic improvement of the processes of personality formation and enhancement of the quality of life of pupils and students of modern educational institutions of various types. PATIENTS AND METHODS: Materials and methods: While working out the basic principles of psychohygienic correction of the processes of personality development and improvement of the quality of life of pupils and students of modern educational institutions of various types, we have conducted surveys of the adolescent boys and girls studying at five modern educational institutions in Ivano-Frankivsk city, namely Vasyl Stefanyk Precarpathian National University, Ivano-Frankivsk Finance Commercial Cooperative College named after Stepan Hranat, Ivano-Frankivsk State Music School named after Denys Sichynskyi, Ivano-Frankivsk Vocational Lyceum of Road Transport and Construction No. 15, and Ivano-Frankivsk Boarding Lyceum for Gifted Young People from Rural Areas. A total of 420 pupils and students studying at different types of educational institutions took part in the survey. They were in both natural and preformed conditions due to application of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students. RESULTS: Results: While conducting the research, we have noted that the practical application of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students occurs at mental, personal and psychophysiological levels of the adolescent boys and girls, anticipating correction of emotional, motivational and behaviour-based key characteristics of personality, psychophysiological adaptation and quality of life, thus being a platform for development of creative potential, self-analysis, self-expression and self-control skills, as well as discovery of positive landmarks and meaning of life of the boys and girls. CONCLUSION: Conclusions: The obtained data demonstrate that implementation of the program of psychophysiological effects on the body, psychohygienic correction of personality development processes and improvement of the quality of life of pupils and students, which includes: study of the level of development of psychophysiological functions, personality characteristics and indicators of the quality of life in each of the participants as well as taking into account the leading areas of their development within certain frameworks of educational process (the milestone of psychodiagnostics and assessment of the level of development of psychophysiological functions and personality traits); performing a set of exercises to relieve muscle spasms, isometric and respiratory gymnastics, as well as exercises of asymmetric gymnastics (the milestone of physical impact); application of psychophysiological component (the milestone of psychophysiological influence); introduction of a psychohygienic component (the milestone of psychohygienic correction) serves the basis for creating the foundation for activating positive changes in the peculiarities of psychophysiological and mental adaptation and characteristics of the quality of life of modern youth at educational institutions of various types.

Fibromyalgia: heterogeneity in personality and psychopathology and its implications.

The fibromyalgia syndrome (FM) is a chronic widespread pain condition whose etiology remains unknown and no treatment has satisfactory levels of success. A meta-analysis has identified a distinct Minnesota Multiphasic Personality Inventory-2 (MMPI-2) clinical profile between FM female patients and healthy controls, and differences between FM and other chronic pain condition with clear etiology have also been found. However, heterogeneity in this population has been suggested in several studies. We aim to assess clinical aspects in FM patients, based on personality psychopathology characteristics, in order to explore heterogeneity and the existence of core common aspects. In this cross-sectional study, a relatively homogeneous sample of 56 female FM patients (Mage = 45.95, SDage = 9.39) was assessed through MMPI-2. A K-Means cluster analysis identified two clusters, one (n = 24) with clinically significant levels in Negative Emotionality and Introversion scales. Subsequent MANOVAs identified important features of this cluster on several MMPI-2 dimensions. Moreover, several dimensions are clinically elevated in both clusters. In conclusion, the combination of psychopathological negative emotionality, interpersonal isolation, and low hedonic capacity, in a group of patients, has implications for the daily living and treatment of FM patients, and several core aspects of FM need to be addressed.

Perceived vulnerability to disease and attitudes towards public health measures: COVID-19 in Flanders, Belgium.

During the COVID-19 pandemic, governments installed measures to contain the disease. Information about these measures was disseminated through news media. Nonetheless, many individuals did not abide by these guidelines. We investigated how perceived vulnerability to disease and personality characteristics related to support for public health measures. We analyzed survey data of 1000 Flemish (Belgium) adults, collected between March 17, 2020 and March 22, 2020. Older age, low educational attainment, gender (female) and work situation (no telecommuting) were associated with greater perceived vulnerability. Greater expectations of loneliness and more solidarity with our fellow men were associated with gender (female), younger age and work situation (telecommuting). Greater perceived vulnerability to disease was related to a greater belief that public health measures protect the population, but also to a critical stance towards the Belgian government's handling of the crisis. High agreeableness and high emotional stability were associated with respectively greater belief that health measures protect the population, and greater support for the government's crisis management. Watching television news was related to a greater belief that public health measures are necessary, and specifically consuming public television news increased support for public health measures. We discuss the implications for handling the COVID-19 pandemic.

Relationship of personality characteristics and eating attitude with the success of bariatric surgery.

Background: Obesity is a chronic disease that causes several medical and psychiatric complications. There are plenty of pharmacological and non-pharmacological therapies for obesity treatment. Bariatric surgery is one of the most efficient nonpharmacological treatment for morbid obesity; however, several psychological factors affect the success of bariatric surgery. This study aims to evaluate personality characteristics and eating attitude relationship with the success of bariatric surgery. Methods: This study was carried out on 75 patients with obesity who were candidates of bariatric surgery in the obesity clinic of Rasoul-e-Akram Hospital in Tehran. The patients were asked to fill the TCI and EAT-26 questionnaires before and after the surgery. Statistical analyses were performed using the SPSS-23 applying T-test, Mann-Whitney tests and Pearson and Spearman's correlation coefficient. The significance level was set at 0.05. Results: Seventy-five patients, including 13 men and 62 women, were assessed through this study. The mean of the BMI of the participants was 44.7 prior to the surgery and 30 after the operation. Personality characteristics and eating attitudes had no significant relationship with the success of bariatric surgery. Conclusion: Although the eating attitude and personal characteristics of the bariatric surgery candidates before the surgery was not related to the outcome of the surgery, they should be considered in post-operational psychological assessments.

[Personality and psychological characteristics of premature ejaculation patients].

OBJECTIVE: To investigate the personality and psychological characteristics of premature ejaculation (PE) patients and the correlation between them two. METHODS: Using Eysenck Personality Questionnaire (EPQ) and Symptom Checklist 90 (SCL-90), we conducted an investigation among 94 PE patients seeking medical advice in Drum Tower Hospital from October 2018 to February 2019. RESULTS: The neuroticism score of the PE patients on EPQ was significantly higher than the national norm of adult males (t = 12.010, P < 0.01), and so was their introversion-extroversion score (t = 2.557, P < 0.05), while their concealment score was markedly lower (t = －8.736, P < 0.01). The coercion score of the patients on SCL-90 was remarkably higher than the national norm of adult males (t = 2.787, P < 0.01), and so were their psychosis score (t = 3.944, P < 0.01) and anxiety score (t = 2.512, P < 0.05). There was a significant correlation between the EPQ and SCL-90 scores of the patients. Psychoticism was found highly positively correlated with terror (r = 0.455, P < 0.01), interpersonal relationship (r = 0.295, P < 0.01), hostility (r = 0.375, P < 0.01), psychosis (r = 0.363, P < 0.01), compulsion (r = 0.284, P < 0.01), depression (r = 0.294, P < 0.01), paranoia (r = 0.336, P < 0.01), somatization (r = 0.400, P < 0.01) and anxiety (r = 0.358, P < 0.01), and so was neuroticism with terror (r = 0.466, P < 0.01), interpersonal relationship (r = 0.611, P < 0.01), hostility (r = 0.509, P < 0.01), psychosis (r = 0.593, P < 0.01), compulsion (r = 0.573, P < 0.01), depression (r = 0.560, P < 0.01), paranoia (r = 0.550, P < 0.01), somatization (r = 0.465, P < 0.01) and anxiety (r = 0.572, P < 0.01). Introversion-extroversion, however, was highly negatively correlated with interpersonal relationship (r = －0.226, P < 0.05) and depression (r = －0.228, P < 0.05), and so was concealment with terror (r= － 0.351, P < 0.01), interpersonal relationship (r = －0.433, P < 0.01), hostility (r = －0.347, P < 0.01), psychosis (r = －0.427, P < 0.01), compulsion (r = －0.345, P < 0.01), depression (r = －0.379, P < 0.01) , paranoia (r = －0.393, P < 0.01), somatization (r = －0.204, P < 0.05) and anxiety (r =－0.237, P < 0.05). CONCLUSIONS: The personality and psychological status of PE patients are different from those of normal males, and some personality characteristics of the patients are correlated with their psychological status, especially with high neuroticism.

Personality and Alexithymic Disparity in Obsessive-Compulsive Disorder Based on Washing and Checking.

The aim of this study was to investigate pathway relationship of personality characteristics and alexithymic traits in OCD symptoms of obsession, and compulsive behavior of washing and checking. Two-hundred and seventy patients diagnosed with OCD were consecutively recruited from the psychiatric outpatient department of a teaching hospital. Structural equation modeling showed those more neurotic, less extraverted and with higher levels of alexithymia difficulty identifying feelings (DIF), difficulty describing feelings (DDF) and externally oriented thinking (EOT) were more likely to develop obsessive thoughts. Those less extraverted was more prone to develop washing compulsions, and those more neurotic were more likely to develop checking compulsions. EOT was the only alexithymic trait to have no gender difference within this group of patients with OCDs. The different personality and alexithymic trait pathways found between OCD obsession, washing and checking symptoms provide support that they may be different subtypes within the OCD diagnosis. Obsession was associated with washing, but not checking. Furthermore, no gender difference was found between the obsession and compulsive symptoms. Extraversion and neuroticism can be used to differentiate washing and checking, and alexithymia to differentiate washing and obsessions. This should be taken into consideration for intervention targeting patients with different OCD symptoms.

[Comparison of Occupational Stress and Its Factors of Workers in An Oil Refinery].

Objective: To explore the differences of occupational stress and its factors between petroleum refining workers and support staffs, and to propose more targeted measures to promote the health of petroleum refining and petrochemical workers. Methods: A questionnaire survey was conducted among 353 petroleum refining workers and 189 employees in the logistics department using the occupational stress inventory revised edition (OSI-R) scale between June 13, 2017 and July 27, 2017. Results: Among the occupational factors, there were significant differences in the job requirements, work risk, job monotony, participation in the decision-making scores among the male workers between labor group and logistics group (P<0.01) . And for female workers in the chemical group and logistics group there were also differences in the value of work control, job requirements, work monotonous, work prospects, improvement of opportunity (P<0.05) . In the aspect of personality traits, the score of work psychological control in chemical group was higher than that of the logistics group, while the organization loyalty score was lower than that of the logistics group. Be-sides, there were significant differences between chemical group and logistics group in the score of A behavior, self-esteem and anxiety traits among female group (P<0.05) . In terms of mitigating factors, there was a significant difference in social support score between chemical group and logistics group among female workers (P<0.01) . Comparison of the two groups of psychological stress showed that the mental health and anxiety status of the chemical group and the logistics group showed a difference (P<0.05) , and female workers in the chemical group job satisfaction score lower than the logistics group, but the body Complaints score higher than the logistics group. Conclusion: The psychological stress response of petroleum refining workers is obviously more serious than the staff of logistics department, and there were significant differences between the two groups on occupational stress factors.

Testing the relationship between personality characteristics, contextual factors and entrepreneurial intentions in a developing country.

Drawing upon the theory of planned behaviour (TPB), we developed and tested a conceptual model which integrates both internal personality factors and external contextual factors to determine their associations with motivational factors and entrepreneurial intentions (EIs). We then investigated if the model of EI applies in a developing country, namely Iran. We also set out to identify the most relevant factors for EI within this developing country context. Do distal predictors of EI including personality factors (i.e. need for achievement, risk taking and locus of control) and contextual factors (i.e. perceived barriers and support) significantly relate to EI via proximal predictors including motivational factors (i.e. attitudes towards entrepreneurship and perceived behavioural control [PBC])? Data were collected on 331 students from 7 public universities. The findings support the TPB for EI in Iran. All three motivational factors related to EI, but PBC showed the strongest association, which is different than in developed country contexts. Possible explanations for these differences are discussed. All three personality characteristics indirectly related to EI via the proximal attitudes towards entrepreneurship and PBC. Perceived contextual support and barriers indirectly related to EI via proximal PBC while perceived barriers also directly related to EI.

[Relationship between exercise adherence and personality characteristics in persons experienced in the Medical Fitness program].

Objective　We examined effective exercise adherence support methods for persons experienced in the Medical Fitness (MF) program to clarify the relation of personality traits with exercise adherence and the factors that improve exercise adherence.Methods　Subjects were 283 adults who had registered as members in the MF program at an affiliate of Hospital A. We implemented an anonymous self-administered questionnaire by postal mail. Using the Japanese version of the Ten Item Personality Inventory (which contains 10 items that measure the Big Five personality traits), we evaluated the following characteristics: "Extraversion", "Agreeableness", "Conscientiousness", "Neuroticism", and "Openness". The subjects who reported exercising regularly at the time of survey were considered persons with subjective exercise adherence.Results　In persons with subjective exercise adherence, "Conscientiousness" was significantly lower (P=0.003) among men and "Neuroticism" was significantly higher (P=0.018) among women when compared to persons with subjective exercise adherence. There was no correlation between the things that emphasize exercise adherence and "Conscientiousness" among men. There was a negative correlation between "can achieve goal" and "Neuroticism" among women.Conclusions　It is essential to consider personality and gender differences when devising exercise adherence support measures for the MF program. Our results suggest that women with high neuroticism do not need "can achieve goal" to maintain their exercise habits; therefore, it is necessary to examine teaching methods that do not focus on only goal achievement as part of exercise adherence support for MF.

Multicultural personality and posttraumatic stress in U.S. service members.

OBJECTIVE: Modern military missions place numerous demands on service members, including tactical, personal, and cultural challenges. The purpose of this study was to explore how domains of multicultural personality (cultural empathy, open-mindedness, social initiative, emotional stability, and flexibility) and combat exposure relate to posttraumatic stress disorder (PTSD) in service members. METHOD: Participants (N = 163) completed the Multicultural Personality Questionnaire, Combat Exposure Scale, and PTSD Checklist-Military as part of an online survey. The majority of participants were Caucasian (87%), mean age was 33 years, and all were deployed at least once to Iraq or Afghanistan RESULTS: Regression results indicated that higher levels of combat exposure and open-mindedness and lower levels of flexibility and emotional stability were significant predictors of higher PTSD severity. The interactions between combat exposure and flexibility and combat exposure and openness were also significant. CONCLUSION: Higher levels of flexibility and emotional stability seem particularly important in their association with lower PTSD severity for service members.

Attention deficit hyperactivity disorder and personality characteristics in older adults in the general Dutch population.

OBJECTIVE: The authors wanted to examine the association between attention deficit hyperactivity disorder (ADHD) and personality characteristics and the potential mediating role of these characteristics in the relationship between ADHD and depression in older adults in the general Dutch population. METHODS: Data from the Longitudinal Aging Study Amsterdam in 2008/2009 were used in a cross-sectional design on 231 participants with and without ADHD aged 60-94 years. Questionnaires assessing self-esteem, self-efficacy, mastery, neuroticism, and social inadequacy were administered. ADHD was measured by means of ADHD diagnosis and level of ADHD symptoms. Linear regression analyses were performed to assess the association between ADHD (symptoms) and personality characteristics. Single and multivariate mediation analyses were performed to examine the mediating role of personality characteristics in the relationship between ADHD (symptoms) and depressive symptoms. RESULTS: ADHD was significantly negatively associated with sense of mastery (B = -2.44, t = -3.14, df = 228, p = 0.002), self-esteem (B = -1.16, t = -2.27, df = 228, p = 0.02), and self-efficacy (B = -2.33, t = -2.02, df = 228, p = 0.045) and positively associated with neuroticism (B = 0.99, t = 4.90, df = 228, p <0.001) and social inadequacy (B = 0.65, t = 3.32, df = 229, p = 0.001). In the single mediation analyses, all personality characteristics were mediators in the relationship between ADHD symptoms and depressive symptoms. In the multivariate analysis only mastery and self-esteem were mediators. CONCLUSION: Older adults with ADHD reported lower self-esteem and sense of mastery and higher levels of neuroticism and social inadequacy than older adults without ADHD. Mastery and self-esteem partly explained the association between ADHD and depressive symptoms in old age. The results implicate that in treatment clinicians should pay attention to the personality characteristics of older adults with ADHD.

Is there a relationship between personality and choice of nursing specialty: an integrative literature review.

BACKGROUND: Personality is deemed to play a part in an individual's choice of work, with individuals' preferencing a profession or field of work that will satisfy their personal needs. There is limited research exploring the personality characteristics of nurses within clearly defined nursing specialty areas. Retaining nurses within specialty areas has workforce implications when vacancies are unable to be filled by appropriately experienced staff. The aim of the review was to determine the current state of knowledge regarding the personality profiles of nurses in specialty areas of nursing practice. METHODS: An integrative literature review was undertaken. Five electronic databases were searched using personality and nursing based keywords. No date limit or research design restriction was applied. Rigorous screening and quality appraisal was undertaken considering the research design, methods and limitations of each manuscript. RESULTS: A review of the 13 included articles demonstrated some variability in the personality characteristics of the nursing specialty groups studied. A relationship was identified between personality characteristics and levels of nursing stress and burnout. CONCLUSION: There is some evidence to suggest a relationship between personality characteristics and nursing specialty choice, burnout and job satisfaction. The published literature is limited and the effect of personality on retention is not well established.

Evaluation of the effectiveness of an aerobic exercise program and the personality characteristics of patients with fibromyalgia syndrome: a pilot study.

[Purpose] The aim of this study was to assess the effectiveness of a 6-week aerobic exercise program on pain, physical function, and psychological status, and to evaluate the personality characteristics of fibromyalgia syndrome (FMS) patients. [Subjects and Methods] Fourteen women with FMS were enrolled. They were trained for a 6-week home-based aerobic exercise program. The Fibromyalgia Impact Questionnaire, the Beck Depression Inventory, the visual analog scale of pain and sleep quality were measured at baseline and at the end of week 6. The personality profiles were evaluated using the Minnesota Multiphasic Personality Inventory (MMPI). [Results] After the exercise program, significant improvements were determined in pain, sleep quality, physical function, depression and FMS symptoms compared to baseline. In addition, the hysteria item (71.21±8.84) of the MMPI was significantly higher in FMS. [Conclusion] Our findings indicate that home-based aerobic exercise may be a useful treatment in the management of FMS. Personality characteristics should be considered during the planning process of the treatment of FMS. Personality is a filter between life events and psychological responses. It is defined to be the integration of effective and behavioral patterns. Long-term studies involving larger clinical samples are needed to define the role of personality characteristics in FMS.

Research of correlation between personality traits and hormones with the nature of pulmonary nodules.

Background: Rising rates of lung cancer screening have contributed to an increase in pulmonary nodule diagnosis rates. Studies have shown that psychosocial factors and hormones have an impact on the development of the oncological diseases. Therefore, we conducted this study to explore the potential relationship between pulmonary nodules pathology and patient personality traits and hormone levels. Methods: This study enrolled 245 individuals who had first been diagnosed with pulmonary nodules in Tangdu Hospital and admitted for surgery. The personality profile of these patients was analyzed on admission using the C-Type Behavioral Scale and hormone levels were measured in preoperative serum samples. Associations between nodule pathology, personality scores, and hormone levels， were then assessed through Statistical methods analysis. Results: Behavioral scale analyses revealed significant differences four items, including depression, anger outward, optimism, and social support (P< 0.05). Specifically, patients with higher depression scores were more likely to harbor malignant pulmonary nodules, as were patients with lower levels of anger outward, social support, and optimism. Univariate analyses indicated that nodule pathology was associated with significant differences in nodule imaging density, CT value, testosterone levels, and T4 levels(P< 0.05), and logistic regression analyses revealed pulmonary nodule imaging density and T4 levels to be significant differences of nodule pathology. Conclusion: The results showed a significant association between nodules pathology and the personality characteristics of the patients (depression, anger outward, optimism, social support), the patients' T4 levels and the imaging density of the nodules.

Correlation analysis of mental health conditions and personality of patients with alcohol addiction.

BACKGROUND: Alcohol addiction, or alcohol dependence, refers to a psychological state of strong craving for alcohol caused by drinking when both the drinking times and alcohol consumption reach a certain level. Alcohol addiction can cause irreversible damage, leading to mental illness or mental disorders, negative changes in their original personality, and a tendency to safety incidents such as committing suicide or violent attacks on others. Significant attention needs to be given to the mental health of alcohol addicts, which could reflect their abnormal personality traits. However, only a few papers on this issue have been reported in China. AIM: To investigate the correlation between mental health and personality in patients with alcohol addiction. METHODS: In this single-center observational study, we selected 80 patients with alcohol addiction as the research subjects, according to the criteria of the K10 scale to evaluate the mental health of patients with alcohol addiction, and divided these patients into four groups based on the evaluation results: Good, average, relatively poor and bad. And then analyzed the correlation between mental health conditions and personality characteristics from these four groups of patients. RESULTS: The average score of the K10 scale (Kessler 10 Simple Psychological Status Assessment Scale) in 80 patients with alcohol addiction was 25.45 points, the median score was 25 points, the highest score was 50 points, and the lowest score was 11 points. Pearson's analysis showed that the K10 score was positively correlated with the scores of these two subscales, such as the P-subscale and the N-subscale (P < 0.05). In contrast, the K10 score had no significant correlation with the scores from the E-subscale and the L-subscale (P > 0.05). CONCLUSION: The mental health conditions of patients with alcohol addiction are positively correlated with their personality characteristics.

Psychological and sociological determinants of entrepreneurial intentions and behaviors.

Research concerned with the personality of entrepreneurs entails an important part of the research into the management of small and medium-sized enterprises and entrepreneurship. This research has added new knowledge about the role of entrepreneurs' personality characteristics, their family entrepreneurial background, and the local supportive entrepreneurial background in entrepreneurial start-up intentions and behaviors. Hypotheses and a model were developed and verified using structural equation modeling and regression analysis considering data from a sample of entrepreneurs and students. This research revealed that several personality and sociological factors can be important for entrepreneurship when it comes to starting a business. The most important were the Big Five personality factors openness, extraversion, and non-agreeableness and, to a smaller extent, emotional stability (non-neuroticism), and conscientiousness. The second-most important group of factors were the specific motivational characteristics entrepreneurial self-efficacy, internal locus of control, and risk-taking propensity. Sociological factors were much less important than psychological elements for establishing business.

Effects of BPD tendencies and subjective well-being on NSSI in adolescents with PTSD.

Background: Severe posttraumatic stress disorder (PTSD) may lead to non-suicidal self-injury (NSSI), and borderline personality disorder (BPD) tendencies may play a role in this process. Secondary vocational students experience more social, familial and other pressures and are more vulnerable to psychological problems. Thus, we explored the effect of BPD tendencies and subjective well-being (SWB) on NSSI in secondary vocational students with PTSD. Methods: A total of 2,160 Chinese secondary vocational students in Wuhan participated in our cross-sectional investigation. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), criteria for PTSD, NSSI Questionnaire, Personality Diagnostic Questionnaire-4+, subjective well-being scale, and family adaptation, partnership, growth, affection, and resolve (APGAR) Index were used. We conducted a binary logistic regression model and linear regression analysis. Results: Sex (odds ratio [OR] = 0.354, 95% confidence interval [CI] = 0.171-0.733), BPD tendencies (OR = 1.192, 95% CI = 1.066-1.333) and SWB (OR = 0.652, 95% CI = 0.516-0.824) were independent factors that predicted NSSI in secondary vocational students with PTSD. Spearman's correlation analysis showed that BPD tendencies were positively correlated with NSSI frequency (r = 0.282, P < 0.01). SWB was negatively correlated with NSSI frequency (r = -0.301, P < 0.01). The linear regression showed that BPD tendencies (ß = 0.137, P < 0.05 and ß = -0.230, P < 0.001) were significantly correlated with NSSI frequency. Spearman's correlation analysis showed that family functioning was positively correlated with SWB (r = 0.486, P < 0.01) and negatively correlated with BPD tendencies (r = -0.296, P < 0.01). Conclusion: In adolescents, PTSD in response to stressful events could lead to NSSI, and BPD tendencies promote the intensity of NSSI, while SWB diminishes its intensity. Improvement in family functioning may actively guide the development of mental health and improve SWB; such steps may constitute interventions to prevent or treat NSSI.
