Potential correlations between abnormal homogeneity of default mode network and personality or lipid level in major depressive disorder.

Default mode network (DMN) is one of the most recognized resting-state networks in major depressive disorder (MDD). However, the homogeneity of this network in MDD remains incompletely explored. Therefore, this study aims to determine whether there is abnormal network homogeneity (NH) of the DMN in MDD patients. At the same time, correlations between clinical variables and brain functional connectivity are examined. We enrolled 42 patients diagnosed with MDD and 42 HCs. A variety of clinical variables were collected, and data analysis was conducted using the NH and independent component analysis methods. The study shows that MDD patients have higher NH values in the left superior medial prefrontal cortex (MPFC) and left posterior cingulate cortex (PCC) compared to HCs. Additionally, there is a positive correlation between NH values of the left superior MPFC and Eysenck Personality Questionnaire values. NH values of the left PCC are positively linked to CHOL levels, LDL levels, and utilization scores. However, these correlations lose significance after the Bonferroni correction. Our findings indicate the presence of abnormal DMN homogeneity in MDD, underscoring the significance of DMN in the pathophysiology of MDD. Simultaneously, the study provides preliminary evidence for the correlation between clinical variables and brain functional connectivity.

The Role of Obsessive Compulsive Traits in Fibromyalgia: Is Pain-Related Obsessive Ideation Involved in Pathogenesis?

Background and Objectives: Fibromyalgia syndrome (FMS) is defined as a chronic pain syndrome that is characterized by widespread pain, tenderness, and diffuse stiffness. In addition, neuropsychological symptoms such as fatigue, sleep disorders, poor mood, cognitive impairment, and headaches are often reported. Many reports have addressed the coexistence of affective disorders and anxiety with FMS, yet few have focused on its association with obsessive compulsive disorder (OCD). We investigated the occurrence of classical patterns of OCD in participants with FMS and assessed their effect on pain perception and functional impairment. Material and Methods: The research population included 37 patients diagnosed with FMS, treated at the Rheumatology Clinic in the Sheba Medical Center, Tel-Hashomer, Israel. We used validated questionnaires including a demographic questionnaire, a questionnaire on average and maximal pain intensity, the Eysenck Personality Questionnaire-Revised (EPQ-R), the Perceived Stress Scale, the Pain Catastrophizing Scale, the Pain Obsessive questionnaire, and the Yale–Brown Obsessive Compulsive Scale (Y-BOCS). Results: Patients with FMS were found to have intrusive and obsessive thoughts regarding pain for several hours every day, causing a high degree of anxiety and high levels of pain, catastrophizing, and magnification, leading to helplessness and functional impairment. In total, 27% of the patients reported severe malfunction due to pain and pain ideation, and 49% demonstrated mild obsessive compulsive symptoms that were strongly correlated with pain intensity and functional impairment. Conclusions: Obsessive compulsive thinking patterns contribute to pain magnification and to the cognitive aspects of fibromyalgia syndrome.

The Effect of Personality Traits of Healthcare Worker Candidates on their Attitudes Towards the Elderly

Background:: It is known that attitudes towards the elderly are an important variable affecting healthcare services. Considering the increasing trends of the population over 65 years in countries, it is important to determine the attitudes of future healthcare workers towards the elderly and to prepare them to serve in the health sector with activities that will lead to positive changes. In this direction, it is important to determine the effect of personality traits of prospective healthcare workers on their attitudes toward the elderly Methods:: The research was conducted using the “relational survey model”. The study was conducted with 581 prospective healthcare workers. Personal Information Form, Eysenck Personality Questionnaire, and Kogan's Scale of Attitudes towards the Elderly were used as data collection tools. Data were obtained and analyzed using the online data collection method. Results:: According to the results of the study, it was found that the attitudes of students who were healthcare candidates for older adults were generally positive ( = 63.46±13.42). While there was a positive yet moderate and statistically significant correlation between attitudes towards the elderly and scores on the Extraversion subscale (r= 0.634, p<0.01) and a negative yet moderate and statistically significant correlation with scores on the Neuroticism (r= -0.568, p<0.01) and Psychoticism (r= -0.602, p<0.01) subscales. The personality traits extraversion, neuroticism, and psychoticism explained 58.6% of the attitude towards the elderly. According to the regression results, extraversion (β= 0.358; p<0.001) positively affected attitudes towards the elderly, whereas neuroticism (β= -0.310; p<0.001) and psychoticism (β= -0.307; p<0.001) negatively affected attitudes towards the elderly. Conclusions:: Given the important role of healthcare professionals in improving the care and quality of life of the elderly, it is necessary to develop strategies to improve the attitudes of future healthcare professionals towards the elderly. Consideration of personality traits in determining these strategies may contribute to the development of effective and personalized approaches.

Salutogenic outcomes and their personality predictors in participants of year-long Antarctic expeditions

Prolonged stays in extreme living and working conditions at Antarctic stations can result in both negative psychological manifestations and possible positive, salutogenic effects. The aim of this study was to check an assumption about existing salutogenic outcomes and their personality predictors in expeditioners who participated in year-long expeditions. We examined 62 expeditioners who participated in expeditions to the Ukrainian Antarctic Akademik Vernadsky station between 1996 and 2021, including 59 men and three women aged 27 to 68 years. We used the Posttraumatic Growth Inventory—Expanded, the General Self-Efficacy Scale, the Eysenck Personality Questionnaire, the Sixteen Personality Factor Questionnaire and the Professional Hardiness Questionnaire. The majority of expeditioners (55–71%, on various grounds) recorded personal growth following Antarctic deployment, at a level from moderate to high. Based on personality characteristics diagnosed in the abovementioned questionnaires, we created an informative prognostic model explaining 30–45% of the variation in several indicators of expeditioners’ post-expedition growth. The most important predictors of expeditioners’ post-expedition growth were indicators of professional hardiness. Our findings provide additional opportunities to improve psychological evaluation and training for Antarctic expedition personnel.

Neuroticism personality, social contact, and dementia risk: A prospective cohort study

BackgroundPersonality traits, especially neuroticism, can influence susceptibility to dementia. Social contact mitigates stress and risk of dementia, the extent to which social contact can mitigate excess risk associated with neuroticism remains unclear. We aim to investigate whether active social contact is associated with lower neuroticism-associated excess risk of dementia. MethodsThis prospective cohort study examined 393,939 UK Biobank participants (mean [SD] age: 56.4 [8.1] years; 53.7 % female) assessed from 2006 to 2010 and followed up until December 2022. Neuroticism was measured using the Revised Eysenck Personality Questionnaire. Social contact levels were assessed based on household size, contact with family or friends, and group participation. Dementia was determined using linked electronic health records. ResultsHigh neuroticism was associated with increased all-cause dementia risk and cause-specific dementia. Among high neuroticism participants, excess risk of all-cause dementia showed a stepwise decrease with increasing social contact (low: hazard ratios (HR) = 1.27, 95 % confidence interval (CI) = 1.15–1.40; intermediate: HR = 1.20, 95 % CI = 1.12–1.28; high: HR = 1.07, 95 % CI = 1.00–1.15). High social contact similarly decreased excess risk of cause-specific dementia, comparable to those with low neuroticism. LimitationsNeuroticism and social contact information relied on self-report questionnaires at baseline, with a potential temporal relationship between these factors. ConclusionActive social contact is associated with a stepwise reduction in excess dementia risk and potentially eliminate excess risk of dementia with high neuroticism individuals, supporting social contact as a preventive strategy to attenuate excess risks of dementia from neuroticism personality trait.

Latent profile analysis of Eysenck's personality dimensions and psychological constructs in university students.

The exploration of personality traits in relation to psychological constructs has become increasingly relevant in understanding the mental health of university students (the emerging adulthood). Studies have focused on how dimensions intersect with various psychological parameters. The study aims to identify distinct personality profiles among university students based on Eysenck's personality dimensions and investigate how these profiles differ across psychological constructs. A quantitative methodology was utilized, involving 708 university students from Wenzhou and Nanjing in China as participants. The research employed the Eysenck Personality Questionnaire along with other psychological measures. Latent Profile Analysis was applied to categorize the participants into distinct personality profiles. Four distinct personality profiles emerged: 'The Reserved Analyst,' 'The Social Diplomat,' 'The Unconventional Pragmatist,' and 'The Impulsive Truth-Teller.' Significant differences were found among these profiles on various psychological constructs. 'The Social Diplomat' exhibited the most adaptive psychological profile, with higher cognitive reappraisal (F = 45.818, p < 0.001, η2 = 0.163), meaning in life (F = 17.764, p < 0.001, η2 = 0.070), and positive coping (F = 40.765, p < 0.001, η2 = 0.148) compared to other profiles. Conversely, 'The Reserved Analyst' showed higher intolerance of uncertainty (F = 13.854, p < 0.001, η2 = 0.056) and state anxiety (F = 26.279, p < 0.001, η2 = 0.101). This study enriches the understanding of personality traits in relation to psychological constructs within the context of university student populations. By identifying distinct personality profiles, it lays the groundwork for developing tailored mental health strategies that cater to the specific needs of different student groups.

Service Quality and Related Factors in Primary Health Care Services: A Cross-Sectional Study.

Primary health care services aim to prevent diseases and improve health efficiently and effectively. This study measures perceived service quality in a primary healthcare organization and examines the effect of personality traits on service quality. The cross-sectional study population comprised individuals over the age of 18 who applied to the Bingöl Central Community Health Centre. A total of 460 participants were included in the study between November 2018 and March 2019. The participants completed a face-to-face questionnaire that included socio-demographic characteristics, the SERVQUAL Scale, and an abbreviated form of the revised Eysenck Personality Questionnaire. This study is based on doctoral research in public health. The study found median values for personality trait sub-dimensions as follows: neuroticism: 2, psychoticism: 2.65, extraversion: 4, and lying: 5. The SERVQUAL Score was -0.02. The study revealed that the quality of primary health care services did not meet the participants' expectations. The study findings also indicated that age, educational attainment, and extraverted and psychotic personality traits were significantly associated with the satisfaction of service quality expectations (p < 0.05). It is recommended to provide primary health care services in facilities with good physical characteristics, with sufficient and competent health personnel, and in a timely and accurate manner to improve service quality.

Brief Version of the Revised-Abbreviated Eysenck Personality Questionnaire in a Spanish Young Adult Population

Eysenck’s PEN model is one of the most relevant and fruitful models with empirical support, and continues eliciting a large research corpus. Nevertheless, the systematic limitations regarding the psychoticism dimension and questionable inclusion of social desirability as a personality dimension have limited the model. The current research aimed to estimate an alternativePEN model including social desirability as a control and test its validity and reliability. This sample consists of 2969 Spanish young adults. Confirmatory factor analysis was carried out to test the fitting of four different models tothe data. Once the best-fitting model was obtained, multiple-group analyses were carried out to assess the configural, metric, and scalar invariance of themodel across sexes. The results showed that the three-dimension PEN model and two-dimension EN model controlling social desirability best fit the dataand were invariant across sexes. Despite the apparent appropriateness of both models, the EN model controlling for social desirability is more appropriate due to the weakness of the P dimension.

Polish Adaptation of the Coparenting Relationship Scale

Abstract: The Coparenting Relationship Scale (CRS) is a 35-item self-report measure used to assess subjective evaluation of the relationship between parents. Developed and applied in the United States, it was translated and adapted in other countries. The article presents a Polish adaptation of the CRS. The study included 802 respondents (514 mothers, 288 fathers). In comparison to the original 7-factor structure of the original CRS, in our case, we excluded the division of labor factor and achieved satisfactory goodness-of-fit criteria upon the inclusion of the method factor with reverse-worded (RW) items. We also attempted to test measurement invariance by gender and across two cultural contexts: comparing with the USA and Switzerland. In all cases, at least scalar invariance was achieved, allowing for comparisons between the mentioned groups. We also verified construct validity, which allowed us to demonstrate convergent validity when the CRS was correlated with the Enrich Marital Satisfaction Scale and Parental Distress Scale, as well as discriminant validity when the CRS was correlated with the Lie Scale from the Eysenck Personality Questionnaire-Revised. The results of statistical analyses show that the Polish CRS is a valid and reliable measure of the coparenting relationship.

EXTRAVERSION, INTROVERSION AND NEUROTICISM IN STUDENT ATHLETES INVOLVED IN SHOOTING SPORTS (according to the Eysenck Personality Questionnaire)

In this article, student shooters (69 people) answer the Eysenck Personality Questionnaire and perform control shooting. The levels of neuroticism and extraversion-introversion and their relationship with shooting results are determined both in the entire group and when divided by category and separately among men and women. It is revealed that the level of extraversion-introversion is not correlated with the shooting result. The level of neuroticism determines the balance of nervous processes and, thus, can influence the shooting result. The level of lying indicates the importance of building trust with shooters.

The Relationship between Attitudes toward Death and Emotional Intelligence, Personality, Resilience, and Justice Beliefs: A Cross-Sectional Study of Midwives in Greece.

Midwifery practice inevitably includes miscarriages, stillbirths, and neonatal deaths. The aim of the present study was to investigate the relationship between attitudes toward death and emotional intelligence, personality, resilience, and justice beliefs among midwives in Greece. A descriptive cross-sectional study was conducted from 2020 to 2022 among 348 midwives employed in public hospitals, in regional health authorities, or as independent professionals. Research instruments included the Death Attitude Profile-Revised, the Connor-Davidson Resilience Scale, the Trait Emotional Intelligence Questionnaire-Short Form, the Eysenck Personality Questionnaire, and the Belief in a Just World scale. The results revealed that greater emotional intelligence was significantly associated with higher scores in the escape acceptance subscale. Midwives scored low on the neutral acceptance subscale (2.9 ± 0.8), with the highest score being recorded in the escape acceptance subscale (4.6 ± 1.0), which was significantly associated with greater emotional intelligence. Neuroticism was significantly associated with the death avoidance, approach acceptance, fear of death, and escape acceptance subscales. Finally, the subscale of distributive justice beliefs for self and others was significantly associated with the subscales of death avoidance and approach acceptance. These findings highlight the nuanced perspectives within the healthcare community. As we delve deeper into the complexities of end-of-life care, understanding these diverse attitudes is crucial for providing comprehensive and empathetic support to both patients and healthcare professionals.

Personality dimensions, resilience, and depression during COVID-19 pandemic: A one-year longitudinal study

BackgroundThe onset of the COVID-19 pandemic has brought to light a significant surge in depression across diverse populations. While a considerable body of research has linked this upswing to lockdowns and restrictive measures, it is crucial to recognize that lockdowns alone cannot fully elucidate the observed increase in mental health disorders, given the vast array of individual psychological responses. ObjectiveThis study aims to test e whether personality dimensions (Extroversion, Neuroticism, and Psychoticism) and resilience play a role in shielding individuals from developing depression during the COVID-19 pandemic, as observed in a sample of Brazilian adults. MethodsThis research employed a one-year longitudinal naturalistic study involving the general population. It utilized a web-based questionnaire administered in three waves during the COVID-19 pandemic: April 2020, September 2020, and May 2021. The research protocol contains the Patient Health Questionnaire-9 – PHQ-9, the Connor-Davidson Resilience Scale – CD-RISC, and the Eysenck Personality Questionnaire Revised-Abbreviated - EPQR-A. ResultsOur study encompassed 455 participants, of which 35.6 % met the criteria for depression in the first wave, and this figure decreased to 18.5 % in the second and third waves (p = 0.001). Resilience levels in the non-depressed group (consistently exhibited higher means across all three waves when compared to the depressed group (first wave: x¯= 27.98; second wave: x¯= 37.26; third wave: x¯= 36.67; p = 0.001). Furthermore, resilience exhibited an overall protective effect against depression in all waves (PR = 0.93, p = 0.000). Neuroticism and Psychoticism emerged as predictors of depression across all waves (PR = 1.346; p = 0.0001 and PR = 1.157; p = 0.030), while the Extroversion dimension showed no significant effect. ConclusionThe decline in depression rates during the first year of the COVID-19 pandemic was influenced by levels of resilience, which acted as a protective factor against the development of depressive symptoms. Notably, Neuroticism and Psychoticism predicted the risk of developing depressive symptoms. Implications for practical intervention in future crisis scenarios suggest the need for public health policy programs featuring personalized interventions that prioritize enhancing resilience.

Personality Traits, Burnout, and Psychopathology in Healthcare Professionals in Intensive Care Units-A Moderated Analysis.

This study explored the associations between personality dimensions, burnout, and psychopathology in healthcare professionals in intensive care units (ICUs). This study further aimed to discern the differences in these relationships when considering the variables of critical care experience (less than 5 years, 5-10 years, and more than 10 years), profession (nurses versus intensivists), and the urban size of the city where the ICU is located (metropolitan cities versus smaller urban cities). This cross-sectional investigation's outcomes are based on data from 503 ICU personnel, including 155 intensivists and 348 nurses, in 31 ICU departments in Greece. Participants underwent a comprehensive assessment involving a sociodemographic questionnaire, the Eysenck Personality Questionnaire (EPQ), the Maslach Burnout Inventory (MBI), and the Symptom Checklist-90 (SCL-90). To analyze the interplay among critical care experience, burnout status, and psychopathology, a moderation analysis was conducted with personality dimensions (i.e., psychoticism, extraversion, and neuroticism) serving as the mediator variable. Profession and the urban size of the ICU location were considered as moderators influencing these relationships. Male healthcare professionals showed higher psychoticism levels than females, aligning with prior research. Experienced nurses reported lower personal achievement, hinting at potential motivation challenges for professional growth. Psychoticism predicted high depersonalization and low personal achievement. Neuroticism and psychoticism negatively impacted ICU personnel's mental well-being, reflected in elevated psychopathology scores and burnout status. Psychoticism appears to be the primary factor influencing burnout among the three personality dimensions, particularly affecting intensivists. In contrast, nurses are more influenced by their critical care experience on their mental health status.

Investigating Correlations between Subjective Satisfaction with Body Image and Selected Personality Characteristics in Gender Adolescents with Attractive Face

Body image just during adolescence is influenced not only by the media, but also by family and friends, and related to this, the adolescent must learn to cope with society's demands on body image. This study examines the relationships between facially attractive adolescents' body image dissatisfaction and personality characteristics. The research population consisted of 185 face-attractive students from different types of high schools, including 89 girls and 96 boys with an average age of 18 years. We used the Eysenck Personality Questionnaire EPQ-R and Stunkard Silhouettes and questions designed by us regarding satisfaction/dissatisfaction with different body parts to collect data. We found that there was no significant relationship between body image dissatisfaction and neuroticism, psychoticism. A significant negative relationship was found between body image dissatisfaction and extroversion.

Self-compassion moderates the relationship between neuroticism and depression in junior high school students.

Neuroticism, an emotion-related personality trait, is often associated with a greater susceptibility to depression. On the other hand, self-compassion involves treating oneself in a peaceful, mindful, and friendly manner, particularly in the face of failure or frustration. The study investigated the relationship between neuroticism and depression in junior high school students, as well as the moderating role of self-compassion. A total of 757 junior high school students participated in the survey, which included the Children's Depression Inventory, the Eysenck Personality Questionnaire-Revised, Short Scale for Chinese, and the Chinese version of the Self-Compassion Scale. The results revealed that neuroticism positively predicted depression, while self-compassion had a significant moderating effect on the relationship between neuroticism and depression. Specifically, higher levels of self-compassion were associated with a weaker link between neuroticism and depression. These findings suggest that interventions promoting self-compassion may be beneficial for students exhibiting neurotic tendencies.

Associations Between a General Factor and Group Factor from the Spanish-Language Eysenck Personality Questionnaire–Revised Short Form’s Neuroticism Scale and the Revised NEO Personality Inventory Domains and Facets

Prior studies used exploratory bifactor analyses to examine the structure of the Neuroticism scale from the Short-scale Eysenck Personality Questionnaire–Revised (EPQ–RS). These studies revealed a general factor and two group factors—Anxious-Tense and Worried-Vulnerable. These factors were related to poorer mental health, but their associations with physical health differed, as did their genetic and neurobiological underpinnings. A later study found that their associations with the Big Five Inventory-2 Short Form’s factors and facets differed. We reanalyzed data on 1,006 Spanish students who completed Spanish-language versions of the EPQ–RS and the Revised NEO Personality Inventory (NEO PI–R). Using confirmatory factor analysis, we showed that a model comprising the general factor and a group factor—Anxious-Tense—fit well. In later correlations, a joint factor analysis, and simultaneous multiple regressions, we showed that the EPQ-RS’s general factor and the group factor had different patterns of associations with the NEO PI–R domains and facets. These associations were consistent with the definition of the EPQ–RS Neuroticism scale’s general factor and that of the group factor. Further investigation into the EPQ–RS Neuroticism scale’s structure can improve our understanding of neuroticism’s relationship with health and other outcomes.

Comparative Analysis of Personality Traits in Major Depressive Disorder and Bipolar Disorder: Impact, Differences, and Associations with Symptoms.

This cross-sectional study aimed to compare the personality traits of patients with major depressive disorder (MDD) and bipolar disorder (BD) with those of healthy individuals. The goal was to gain insight into the potential impact of personality traits on the development and manifestation of mood disorders. One hundred seventy-eight patients with mood disorders were analyzed as either MDD or BD, with each group containing euthymic and depressive members: e-MDD, d-MDD, e-BD, and d-BD. Mood status was assessed using the Young Mania Rating Scale (YMRS), and the 17-item Hamilton Depression Rating Scale (HAMD-17). Ninety-five healthy individuals served as controls. Personality traits were assessed with the Eysenck Personality Questionnaire. The scores for neuroticism in the patient groups were comparable, but each group had higher scores compared to the control group (P < 0.001). Each patient group exhibited significantly lower scores for extraversion compared to the control group, with e-MDD, d-MDD, and d-BD showing particularly notable differences (P < 0.001); these groups scored significantly lower than the e-BD (P = 0.041, 0.009, 0.038). In patients with BD, there was an inverted association between extraversion score and HAMD total score (P = 0.010, r = -0.27), and a positive association with the YMRS total score (P = 0.022, r = 0.24). In the MDD group, there was a positive association between the neuroticism score and HAMD total score (P = 0.021, r = 0.25). Patients with mood disorders are characterized by lower extraversion and higher neuroticism. Level of neuroticism associated with depression severity in MDD. Patients with BD may be more extraverted, but their extraversion can be affected by depressive episodes. Extraversion may be a feature of BD, and may differentiate BD from MDD. Personality traits are related to disease diathesis and state, and shaped by symptom manifestations.

Personality differences among acculturation profiles of Chinese domestic migrants: A person-centered approach

We explored acculturation profiles among Chinese domestic migrants and examined the variation in personality traits across these profiles. Questionnaires assessing acculturation patterns and personality traits were completed by 816 participants. Acculturation patterns were measured by the East Asian Acculturation Measure and personality traits were measured with the Eysenck Personality Questionnaire???Revised, Short Scale. Four profiles with personality differences were identified using latent profile analysis: less acculturated, highlyacculturated,marginalized,andmoderatelybicultural.Adoptingapersoncentered approach was underscored by these findings, suggesting that the government could design a targeted strategy aimed at facilitating adjustment among higher risk domestic migrants (e.g., those with marginalized or less-acculturated profiles) with particular personality traits, such as high levels of neuroticism and low extraversion.

Association between dopamine receptor D2 Taq IA gene polymorphism (rs1800497) and personality traits.

This study aimed to find a potential association between the DRD2 Taq1A gene polymorphism (rs1800497 C32806T) and personality traits. In all, 249 youths were recruited for this study. The Short-form Revised Eysenck Personality Questionnaire was administered to assess personality traits. The participants were genotyped for the DRD2 Taq1A polymorphism using the polymerase chain reaction-restriction fragment length polymorphism method. Statistical analysis was carried out to find a possible association between the genotypes and aspects of personality traits assessed. The frequencies of the A1 and A2 alleles in our sampled population were 215 (43.2%) and 283 (56.8%), while the frequencies of A1A1, A1A2, and A2A2 were 67 (26.9%), 81 (32.5%), and 101 (40.6%), respectively. The study population was not in Hardy-Weinberg equilibrium (χ2 = 17.64, p < 0.001). The A2 allele was significantly associated with extraversion. Although this allele was also associated with neuroticism, psychoticism, and lie, the association was not significant. The A2 allele of the DRD2 Taq1A polymorphism was found to be more associated with extraversion, as measured by the Short-form Revised Eysenck Personality Questionnaire.

Effect of Personality and Pain Catastrophizing on Postoperative Analgesia Following Cesarean Section: A Prospective Cohort Study.

This study aimed to investigate the effects of different psychological personalities and pain catastrophizing levels on postoperative analgesia in patients undergoing cesarean section. Puerperas who underwent cesarean section at our hospital between January and August 2023 were recruited into the study and assessed using the Eysenck Personality Questionnaire-Revised Short Scale (EPQRSC) and Pain Catastrophizing Scale (PCS). Data on the numerical pain intensity at rest and during activity 24 h after surgery, number and dosage of analgesia pumps, and satisfaction with analgesia were recorded. According to the numerical pain score during activity 24 h post-operation, the patients were divided into the analgesia incomplete group (≥4) and control group (<4). Univariate analysis, Spearman correlation analysis, and binary logistic regression analysis were used to evaluate the influence of personality characteristics and PCS on postoperative analgesia. A total of 778 women were included in the study. The incidence of inadequate analgesia was 89.8%. The satisfaction rate of analgesia was 66.8%. Univariate analysis showed that extraversion; neuroticism; PCS; numbers of previous cesarean delivery; ASA; analgesic satisfaction; and 24-h analgesia pump compressions and dosage were associated with postoperative analgesia after cesarean section (P<0.05). Using binary logistic regression analysis, the first cesarean section (odds ratio [OR]=0.056, 95% confidence interval [CI]=1.913-19.174), the number of 24-h analgesic pump compressions (OR=8.464, 95% CI=0.356-0.604), extraversion (OR=0.667, 95% CI=0.513-0.866), neuroticism (OR=1.427, 95% CI=1.104-1.844), and PCS (OR=7.718, 95% CI=0.657-0.783) were factors affecting postoperative analgesia. The incidence of inadequate analgesia after a cesarean section was high (89.8% on the first day after surgery). Formulating accurate analgesia programs for women undergoing cesarean section with extraversion, neuroticism personality characteristics, and pain catastrophizing behaviors is necessary for improving their postoperative analgesia effects and satisfaction and promoting postpartum comfort.
