The Influence of Genetic Polymorphic Variability of the Catechol-O-methyltransferase Gene in a Group of Patients with a Diagnosis of Behavioural Addiction, including Personality Traits.

Gambling Disorder (GD) is characterised by a harmful, enduring, and recurrent involvement in betting-related behaviours. Therefore, GD shares similar biological mechanisms and symptoms to substance use disorders (SUD). Therefore, in this study, we chose the behavioural addictions group. During the examination and recruitment to the study, it turned out that all the people undergoing treatment for gambling addiction were also addicted to amphetamines, which is consistent with the biological mechanism related to cerebral neurotransmission. The aim of the study was to investigate the association of the COMT gene polymorphism with behavioral addiction. The study group consisted of 307 participants: 107 men with gambling disorder and amphetamine dependency (mean age = 27.51, SD = 5.25) and 200 non-addicted, nor dependent, free from neuro-psychiatric disorders control group men (mean age = 20.20, SD = 4.51). Both groups were subjected to psychometric evaluation using the State-Trait Anxiety Inventory and the NEO Five-Factor Personality Inventory. Genomic DNA was extracted from venous blood following standard protocols. Determination of the rs4680 polymorphism in the COMT gene was performed using the real-time PCR technique. Statistically significant differences in the frequency of rs4680 genotypes were found in the tested sample of subjects compared with the control group (p = 0.03543). Subjects with gambling disorder and amphetamine use disorder compared to the control group obtained higher scores in the assessment of the STAI trait scale (p = 0.0019), state scale (p < 0.0000), and NEO-FFI Neuroticism scale (p < 0.0000). Significantly lower results were obtained for the NEO-FFI Agreeability scale (p < 0.0000). Additionally, a significant statistical impact of gambling disorder and amphetamine use disorder, and the COMT rs4680 genotype was demonstrated for the score of the STAI trait (p = 0.0351) and state (p = 0.0343) and the NEO-FFI Conscientiousness scale (p = 0.0018). We conclude that COMT and its polymorphic variant influence the development of addiction. Still, considering its multifactorial and polygenic nature, it should be combined with other factors such as personality.

The HINT1 Gene rs2526303 Polymorphism and Its Association with Personality Traits in Cigarette Smokers.

The development of a substance use disorder (SUD) is a multifaceted process influenced by both genetic and environmental factors. Recent research has suggested the potential involvement of the HINT1 gene in various aspects of plasticity, mood regulation, anxiety-like behaviour, and stress-coping mechanisms. Moreover, personality traits are also recognised to be instrumental in developing substance dependency. Given these considerations, our study investigated the associations among cigarette smoking, personality traits, and the rs2526303 polymorphism. Additionally, we investigated the interactions between personality traits and rs2526303 in the HINT1 gene. The study group comprised 531 volunteers: 375 cigarette users (mean age = 29.42 ± 10.72; F = 49%, M = 51%) and 156 never-smokers (mean age = 26.93 ± 10.09; F = 79%, M = 21%). Genotyping was conducted using the real-time PCR method, and the NEO Five-Factor Personality Inventory and State-Trait Anxiety Inventory were administered. There were no statistically significant differences in the frequency of rs2526303 genotypes and alleles in the cigarette user group compared to the control group. Compared to the control group, the cigarette users obtained higher scores in the assessment of the NEO-FFI Extraversion scale and lower results for the NEO-FFI Openness, Agreeableness, and Conscientiousness scales. Additionally, there was a statistically significant effect of rs2526303 genotype interaction and cigarette-using status on the conscientiousness scale. These outcomes collectively suggest a notable association between cigarette smoking and specific dimensions of personality, particularly highlighting differences in extraversion, openness, agreeableness, and conscientiousness. Furthermore, the detected interaction effect involving rs2526303 concerning conscientiousness signifies a complex interplay between genetic factors and smoking behaviour.

Association of Personality Traits with Treatment Adherence in Vitiligo

Background: Vitiligo is an acquired, auto-immune chronic skin disorder with different treatment modalities. Insufficient adherence to treatment is closely related to the efficacy of a prescribed treatment, and also, there are some associations between adherence behaviour and personality. Therefore, the study aimed to assess a relationship between five-factor personality traits and treatment adherence in patients with vitiligo.&#x0D; Methods: In this cross-sectional study, patients with vitiligo who received Ultraviolet B (UVB) phototherapy were recruited. The Morisky Medication Adherence Scale (MMAS-8) assessed treatment adherence, and personality factors were evaluated by NEO Five-Factor Personality Inventory (NEO-FFI). Data were analysed using t-tests, correlations, and multiple regression.&#x0D; Results: Among 70 participants, 62.9% had low adherence, 24.3% had medium adherence, and 12.9 % had high adherence. There was a positive correlation between neuroticism (p&lt;0.001) and adherence score. Furthermore, a negative correlation between Agreeableness (p=0.13), Conscientiousness (p&lt;0.001), Openness to experiences (p=005), Extraversion (p&lt;0.001), and adherence score was obtained. In the regression analysis method, only the factors of neuroticism (p&lt;0.001) and openness ( p=0.001), and conscientiousness ( p=0.016) predicted the dependent variable (adherence score) at the significance level.&#x0D; Conclusion: This study demonstrated that openness to experience and conscientiousness positively affected adherence, while Neuroticism negatively affected adherence. Considering these personality factors can effectively screen poor adherence and improve treatment adherence.

Predicting the Desire for Remarriage Based on Family Relationships, Attachment Styles, and Personality Traits Among Married Men

The present study aimed to investigate the multifaceted relationships between family relationships, attachment styles, and personality traits with the desire for remarriage among married men in Isfahan. The research method was descriptive and correlational. The statistical population consisted of all married men in Isfahan during the years 2016-2017. The sample included 195 married men selected through convenience sampling. The research instruments were the Remarriage Desire Scale, the Family Relationships Questionnaire (Olson &amp; Barnes, 2004), the Attachment Styles Questionnaire (Armsden &amp; Greenberg, 1987), and the NEO Five-Factor Personality Inventory (Costa &amp; McCrae, 1997). Data were analyzed using both descriptive statistics (mean and standard deviation) and inferential statistics (Pearson correlation and stepwise regression analysis). Analyses were conducted using the SPSS statistical package. Results showed that the predictor variables of family relationships, insecure attachment style with father, neuroticism, agreeableness, and conscientiousness significantly related to the desire for remarriage among married men, with family relationships having predictive power for the desire for remarriage in married men. Based on these results, it can be said that an increase in the experience of satisfactory family relationships, conscientiousness, and agreeableness reduces men's desire for remarriage, while neuroticism and insecure attachment style with father increase the desire for remarriage in these men. Additionally, satisfactory family relationships can predict a decrease in the desire for remarriage among married men. Thus, if women can form a good relationship with men, they can reduce their husbands' desire for remarriage.

Association between Polymorphism rs1799732 of DRD2 Dopamine Receptor Gene and Personality Traits among Cannabis Dependency.

Compared to other addictive substances, patients with cannabis addiction are significantly outnumbered by those who report dependence on other, more addictive substances. Unfortunately, most cannabis addiction goes untreated, and among those who choose treatment, the requirements are much higher for adolescents and young adults. The aim of the study: To examine the relationship of cannabinoid dependency in the genetic context—the association between the rs1799732 polymorphism of the DRD2 gene and psychological traits and anxiety. Methods: The study group consisted of 515 male volunteers. Of these, 214 patients were diagnosed with cannabis addiction and 301 were non-addicted. Patients were diagnosed with NEO Five-Factor Personality Inventory (NEO-FFI), and State–Trait Anxiety Inventory (STAI) questionnaires. The interactions between personality traits and polymorphisms in the DRD2 rs1799732 gene were investigated in a group of cannabis-addicted patients and non-addicted controls using the real-time PCR method. Results: Compared to the control group, the case group obtained significantly higher scores on the STAI State, STAI Trait, Neuroticism and Openness scales, as well as lower scores on the Extraversion, Agreeableness, and Conscientiousness scales. There was no statistically significant difference between addicts and the control group in the frequency of genotypes, but there was a statistically significant difference between addicts and the control group in the frequency of the DRD2 allele rs179973. The multivariate ANOVA analysis showed a statistically significant influence of the DRD2 rs1799732 genotype on the NEO-FFI agreeableness scale and a statistically significant effect of addiction to cannabinoids or its absence on the NEO-FFI agreeableness scale score. Conclusions: Studying homogeneous subgroups—as in our study—seems reasonable, particularly when combined with genetic determinants and psychological traits. In multigenic and multifactorial entities, such a strategy has a future.

Personality and Age of Male National Team of Ukraine in Kyokushin Karate-Pilot Study.

This article is a continuation of the research on personality in combat sports in karate. The authors’ goal was to verify the relationship between personality and age of kyokushin karate practitioners. The male national team of Ukraine in karate kyokushin (N = 7) participated in the personality study with the use of the Big Five model. The NEO-FFI (NEO Five-Factor Inventory) Personality Questionnaire was applied as a research tool and the package of statistical methods IBM SPSS Statistics 27.0 (IBM Polska, Warszawa, Poland) was used to compute the research results. The study showed that there were differences in the intensity of openness to experiences between individual samples only at the level of the statistical trend. Masters showed a higher level of openness to experiences in relation to juniors (p = 0.081) and seniors (p = 0.097). Also, a negative and strong correlation between the intensity of neuroticism and conscientiousness among the respondents was noted. A conclusion was drawn that, with age, karatekas probably manifest greater openness to experience, which is the result of their sports experience, high sports level and pro-health values of karate. On the other hand, good emotional adaptation of karatekas is strictly related to conscientiousness.

Prožívaná smysluplnost v kontextu osobnostních rysů budoucích učitelů

Background. The individually experienced fulfilment of one's own life is utterly unique. It is a very important experience with regard to the quality of life of each individual and their mental health and work performance. This topic has attracted increased research interest in the Czech Republic in recent decades, especially in the discourses of psychology and pedagogy. Methods. The research study documented in this contribution deals with the experience of life fulfilment and existential grounding in a group of university students who were future teachers (n = 346, of whom 294 were women) aged 19–27 years. Two questionnaires were used to collect the data, specifically the Logo-test and the NEO five-factor personality inventory. The data that was obtained was analysed in the context of selected personality traits (extraversion, friendliness, conscientiousness, neuroticism, openness to experience); other factors that were observed were differences between the sexes, age, year of study, and form of study. The complementary qualitative processing of the data that was obtained also included free subjective statements about the life stories of 282 of the respondents. Results. The determined level of lived meaningfulness of life was correlated with selected personality variables of the respondents by means of statistical processing. The results of the research show a significant positive link between the degree of lived meaningfulness and the representation of the personality traits of extraversion, friendliness, openness to experience, and conscientiousness. A negative relationship was found between the personality variable of neuroticism and the degree of meaningfulness that was experienced. Conclusions. The results of the survey can be considered very favourable; they convincingly demonstrate a sufficiently meaningful and existentially rooted life for the majority of the respondents from the ranks of future teachers (95.6% of the respondents). A level of experienced meaningfulness which is questionable and thus endangers the further development of the individualʼs personality or the respondent lacks it altogether was only found in a negligible part of the sample (4.4%). In connection with the future profession of the group of people who were observed, in which they will wield a significant influence on the personality of their pupils and students, it can be concluded that our results are pleasing.

Analysis of Relationships between DAT1 Polymorphism Variants, Personality Dimensions, and Anxiety in New Psychoactive Substance (Designer Drug) (NPS) Users.

The use of ‘new psychoactive substances’ appears to be increasingly common. The aim of this study was to examine biological and personality determinants in individuals who choose to use these substances, which may help in the prevention and treatment of psychoactive substance use disorders. The study group consisted of 374 male volunteers; all were users of ‘new psychoactive substances’ (NPS). The NPS users were recruited after they had abstained—for at least 3 months—from any substance of abuse in addiction treatment facilities. The NPS patients and the control subjects were examined by a psychiatrist using the Mini-International Neuropsychiatric Interview (M.I.N.I.), the NEO Five-Factor Personality Inventory (NEO-FFI), and the State-Trait Anxiety Inventory (STAI) scales. The real-time PCR method was used for genotyping. When we compared the controls with the study group, statistically significant interactions were found between DAT1 polymorphism, neuroticism, and NPS use. NPS use and DAT1 polymorphism were associated with a higher level of neuroticism on the NEO-FFI scale. The study group of NPS users showed a higher severity of anxiety symptoms, both in terms of trait and state, compared to the control group. The results may support the idea that neuroticism and anxiety correlate strongly with coping motives for using NPS.

DRD4 Exon 3 Gene Polymorphisms in Patients Diagnosed with Polysubstance Use Disorder and Co-Occurrence of a Depressive Episode.

Background: There has been a noticeable and systematic growth of the use of psychoactive substances over the past few decades. Dual diagnosis is a clinical term referring to the occurrence of psychoactive substance use disorder comorbid with another psychiatric disorder in the same person. The most common type of dual diagnosis is the co-occurrence of alcohol use disorder and mood disorders in the form of a depressive episode. Co-occurrent substance use disorders are frequently influenced by genetic factors. In selecting our area of research, we focused on dopamine and the DRD4 (Dopamine Receptor D4) gene polymorphism as well as associations with personality features. The aim of the study: The aim of the study was to compare DRD4 exon 3 (DRD4 Ex3) gene polymorphisms in patients diagnosed with polysubstance use disorder and co-occurrence of a depressive episode to DRD4 exon 3 gene polymorphisms in patients diagnosed with polysubstance use disorder and without co-occurrence of a depressive episode and a group of healthy volunteers. The study also aimed at establishing associations between personality features and DRD4 exon 3 gene polymorphisms of male patients diagnosed with polysubstance use disorder with co-occurrence of a depressive episode which may present a specific endophenotype of this group of patients. Methods: The study group comprised 602 male volunteers: patients diagnosed with polysubstance use disorder comorbid with a depressive episode (PUD MDD) (n = 95; mean age = 28.29, standard deviation (SD) = 7.40), patients diagnosed with polysubstance use disorder (PUD) (n = 206; mean age = 28.13, SD = 5.97), and controls (n = 301; mean age = 22.13, SD = 4.57). The patients and control subjects were diagnosed by a psychiatrist using the Mini International Neuropsychiatric Interview (MINI), the NEO Five-Factor Personality Inventory (NEO-FFI), and the State-Trait Anxiety Inventory (STAI) questionnaires. An analysis of the DRD4 exon 3 polymorphism was performed. Results: The patients diagnosed with PUD MDD compared to the control group of healthy volunteers showed significantly higher scores on both the STAI status and features scale and the NEO-FFI Neuroticism and Openness Scale, as well as lower scores on the Extraversion, Agreeableness, and Conscientiousness NEO-FFI scales. In the DRD4 exon 3 gene polymorphism, the s allele was more frequent in the PUD MDD compared to the l allele, which was less frequent. The results of the 2 × 3 factor analysis of variance (ANOVA) in patients and controls and the variant DRD4 exon 3 interaction were found on the Extraversion Scale and the Conscientiousness Scale of the NEO-FFI. Conclusions: The associations show that psychological factors combined with genetic data create a new area of research on addiction, including the problem of dual diagnosis. However, we want to be careful and draw no definite conclusions at this stage of our research.

Influence of DAT1 Promotor Methylation on Sports Performance.

In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. DNA methylation regulates gene expression by recruiting proteins involved in gene repression or by inhibiting the binding of transcription factors (TFs) to DNA. As there are still many questions concerning the role of methylation in creating personality, we concentrated on searching for such associations. The research group was 100 sports male subjects (mean age = 22.88, SD = 6.35), whereas the control group included 239 healthy male volunteers matched for age (mean age = 21.69, SD = 3.39), both of European origin. The methods used in our research were as follows: DNA isolation, methylation-specific PCR, sequencing chromatophores, all conducted according to the manufacturer’s procedure. To evaluate personality traits, the NEO Five-Factor Personality Inventory (NEO-FFI) and STAI Inventory were used. We observed the existence of a statistically significant correlation for all the aspects of personality covered and CpG islands’ methylation. Nonetheless, we think that the tested group and the number of tested promotor islands in the DAT1 gene are still too small to make explicit conclusions, so it needs further profound analysis.

Association Analysis of Polymorphic Variants of the BDNF Gene in Athletes.

As BDNF is one of the group of neurotrophins highly influencing the processes happening in the brain, such as the processes of learning and personality creation, we decided to look closer at its genetic variations in association with the personality of a group of athletes and their controls. The study group consisted of 305 volunteers: martial arts athletes (n = 153; mean age = 24.06) and healthy non-athletes as controls (n = 152; mean age = 22.23). Thirty-eight percent of the martial arts group achieved the championship level. Both the martial arts and control subjects were examined using the NEO Five-Factor Personality Inventory (NEO-FFI) and the State-Trait Anxiety Inventory (STAI) scales. The results of the NEO-FFI and STAI inventories were given as sten scores. The conversion of the raw score to the sten scale was performed according to Polish norms for adults. Genomic DNA was extracted from blood leukocytes and then genotyped using a PCR method for the following polymorphisms: BDNF rs10767664 and BDNF rs2030323. We observed statistical significance for both polymorphisms when comparing martial arts athletes with the control group in relation to the conscientiousness and extraversion scales. However, since few extant articles consider this association, our results still require further analysis, probably by considering a larger group.

Neuroticism Is Associated with Tau Pathology in Cognitively Unimpaired Individuals with Autosomal Dominant Alzheimer's Disease.

Greater neuroticism has been associated with higher risk for Alzheimer's disease (AD) dementia. However, the directionality of this association is unclear. We examined whether personality traits differ between cognitively-unimpaired carriers of autosomal-dominant AD (ADAD) and non-carriers, and are associated with in vivo AD pathology. To determine whether personality traits differ between cognitively unimpaired ADAD mutation carriers and non-carriers, and whether the traits are related to age and AD biomarkers. A total of 33 cognitively-unimpaired Presenilin-1 E280A mutation carriers and 41 non-carriers (ages 27-46) completed neuropsychological testing and the NEO Five-Factor Personality Inventory. A subsample (n = 46; 20 carriers) also underwent tau and amyloid PET imaging. Carriers reported higher neuroticism relative to non-carriers, although this difference was not significant after controlling for sex. Neuroticism was positively correlated with entorhinal tau levels only in carriers, but not with amyloid levels. The finding of higher neuroticism in carriers and the association of this trait with tau pathology in preclinical stages of AD highlights the importance of including personality measures in the evaluation of individuals at increased risk for cognitive impairment and dementia. Further research is needed to characterize the mechanisms of these relationships.

Analysis of Personality Traits in Patients with Hodgkin Lymphoma.

Hodgkin lymphoma (HL) is a highly-curable malignancy mostly affecting young people. As far as we know, there is no published study that has analyzed personality profiles in HL nor their potential role in lymphomagenesis, natural history, or response to treatment. We aim to explore the personality traits of HL patients, as well as the prevalence of mental disorders and suicide ideas. We retrospectively identified all alive HL patients from three centers (Son Espases and Son Llatzer University Hospitals and Hospital del Mar of Barcelona) for using NEO Five-Factor Inventory (NEO-FFI) and Personality Inventory for DSM-5 Brief Form. Patients with HL showed significantly higher neuroticism scores and lower conscientiousness, extraversion, and openness. Considering maladaptive personality traits, HL patients showed higher levels of detachment and psychoticism. All of these translated into the fact that HL patients showed more than double the prevalence of mental illnesses (41%) and more than triple the prevalence of suicidal ideation or attempts than the general population (15 and 6%, respectively). An exploratory analysis of biomarkers associated with HL personality traits showed that higher scores of neuroticism correlated with more elevated erythrocyte sedimentation rate (ESR) and red cell distribution width (RDW), suggesting a potential link between neuroticism and proinflammatory activity in HL.

The Mediating Role of Alexithymia in the Relationship of Coping Strategies and Personality Traits With Obsessive-Compulsive Disorder

Aims: Obsessive-Compulsive Disorder (OCD) is one of the severe psychological health problems imposing considerable social and economic costs on society. OCD debilitating symptoms can disrupt interpersonal relations, job performance, and life quality. The purpose of this study is to investigate the mediating role of alexithymia in the relationship between coping strategies and personality traits with OCD. Methods &amp; Materials: This is a descriptive correlational study. The study population consists of all people with OCD referred to psychiatric clinics in Kerman City, Iran, during 2018-2019. Of this population, 200 patients were selected using a convenience sampling method. Research instruments included the ways of coping questionnaire, NEO five-factor personality inventory, Toronto alexithymia scale, and Maudsley obsessive-compulsive test. The obtained data were analyzed using the Pearson correlation test and simultaneous and hierarchical regression in SPSS v. 23. Findings: Personality traits had a negative significant correlation with alexithymia (r=0.523, P&lt;0.000) and OCD (r=0.253, P&lt;0.000). Alexithymia had a significant positive correlation with OCD (r=0.272, P&lt;0.000). There was no correlation between problem-focused coping and alexithymia (r=-0.045, P&lt;0.531). There was a positive correlation between emotion-focused coping and OCD (r=0.198, P&lt;0.000). The fit indices indicated a good fit of the proposed model (P&lt;0.005). Conclusion: Alexithymia, as a mediator of the relationship between coping styles and personality traits with OCD, plays an essential role in improving the psychological health of people with OCD.

Personality and stress influence vision restoration and recovery in glaucoma and optic neuropathy following alternating current stimulation: implications for personalized neuromodulation and rehabilitation

PurposeIdentifying factors that affect recovery or restoration of neurological function is a key goal of rehabilitation in neurology and ophthalmology. One such factor can be prolonged mental stress, which may be not only the consequence of nervous system damage but also a major risk factor, or cause, of neural inactivation. Using the visual system as a model of neural injury, we wished to study how patients’ stress and personality profiles correlate with vision recovery as induced by therapy with alternating current stimulation (ACS) in patients with optic nerve damage.MethodsPersonality and stress questionnaires were sent retrospectively to a clinical convenience sample of patients who suffer low vision due to optic nerve damage, which had previously been treated with ACS. The questionnaires included the NEO Five-Factor Inventory (NEO-FFI), the Trier Inventory of Chronic Stress (TICS), and the Flammer syndrome (FS) checklist, which probes signs of vascular dysregulation (VD). These scores were then correlated with the extent of ACS-induced vision restoration as recorded 1–3 years earlier by perimetric visual field tests.ResultsTwo NEO-FFI personality factors (lower neuroticism, higher conscientiousness) and the presence of physiological Flammer signs were associated with greater recovery as were individual items of the factors openness and agreeableness. Single NEO-FFI item analysis revealed that recovery relates to greater extraversion (optimistic and happy), openness (less guided by authorities for decisions on moral issues), and agreeableness (argue less, like working with others, thoughtful, considerate) as well as the presence of FS signs (cold hands/feet, hypotension, slim body shapes, tinnitus). This suggests that patients with better recovery were more calm, peaceful and secure, hard-working, and reliable, and with high organizational skills. In contrast, patients with poor recovery had a tendency to be emotionally unstable, anxious, unhappy and prone to negative emotions, impulsive, careless, and unorganized. Chronic stress assessed with TICS did not correlate with recovery.ConclusionVision restoration induced by ACS is greater in patients with less stress-prone personality traits and those who show signs of VD. Prospective studies are now needed to determine if personality has (i) a causal influence, i.e., patients with less stress-prone personalities and greater VD signs recover better, and/or (ii) if personality changes are an effect of the treatment, i.e., successful recovery induces personality changes. Though the cause-effect relationship is still open, we nevertheless propose that psychosocial factors and VD contribute to the highly variable outcome of vision restoration treatments in low vision rehabilitation. This has implications for preventive and personalized vision restoration and is of general value for our understanding of outcome variability in neuromodulation and neurological rehabilitation.

Subjective Well-being, Personality, and Loneliness as Correlates of Saudade: A Preliminary Study

AbstractSaudade is a psychological reaction to the absence of significant others or familiar places. The correlates of the experience of saudade were examined using a sample of Portuguese adults. Two hundred and twenty-seven participants of both genders, aged 20–65, were presented with (a) the Satisfaction with Life Scale (SWLS), (b) the Positive and Negative Affect Schedules (PANAS), (c) the brief Loneliness Scale (ULS-6), (d) the Neo Five-Factor Personality Inventory (NEO-FFI), and (e) an experience of saudade two-item scale. Experience of saudade was more often reported by females than by males, and positively correlated with negative affect, loneliness, and neuroticism.

ÜNİVERSİTE ÖĞRENCİLERİNDE TANRI ALGISI VE KİŞİLİK ÖZELLİKLERİ ARASINDAKİ İLİŞKİNİN İNCELENMESİ

The purpose of this study is to examine the relationship between university students God perception and personality traits. The relationship between God and human is an important issue addressed in the psychology of religion.In this context, how the individual perceives God in the world of emotion and thought and the effect of these visions on the personality traits of the individual are the basis of our study.The sample of the study consists of 400 undergraduate students at Sakarya University and Uludag University in the spring term of 2019-2020. As data collection instruments, Personal information form, the Perception of God Scale and Neo-Five Factor Personality Inventory were applied. In addition, a question has been added about parents' attitude.What is the analysis of the findings Mann Whitney U, Kruskal Wallis Test and Spearman correlations analysis were used. It was determined that positive God perception and extroversion, responsibility and agreeableness personality traits were positively correlated; negative God perception and nevroticism personality traits were positively related. Also in the research it was determined that individuals who grew up with authoritarian oppressive mother attitude had a higher negative perception of God.

Personality Dimensions of Speech–Language Pathologists who Work With Clients who Stutter

The personality characteristics of the speech–language pathologists (SLPs) may impact their success with each client they see, specifically in stuttering therapy. This initial study explores a general personality profile of SLPs who work in the area of stuttering compared with SLPs who do not. Personality dimensions were measured by the NEO Five-Factor Inventory (NEO-FFI). An occupational questionnaire was also administered. Results from 142 respondents were available for the analysis. Results indicated a significant interaction of group affiliation and patterns of NEO-FFI personality dimensions. SLPs who work with persons who stutter (PWS) were characterized by lower levels of Neuroticism. Lower Neuroticism levels, which are associated with elevated resilience to anxiety, may be a personality trait of SLPs who choose to work with PWS. Possibly, the SLPs’ resilience may facilitate a better therapeutic alliance with stuttering clients. We discuss the importance of the personality dimensions of the SLPs in the SLPs’ career education.

Personality profiling of South African rugby union players

This study aimed to investigate whether differences exist in the personality profiles of professional and semi-professional rugby union players. Participants were 73 male rugby players, 52 professional players and 21 semi-professional players. All participants completed the NEO Five-Factor Personality Inventory (NEO-FFI) as part of the WebNeuro Sport online assessment. An independent sample t-test showed a statistically significant difference in neuroticism between the professional and semi-professional players. The magnitude-based inference method confirmed the results of the independent sample t-test with a moderate effect. The potential practical value of these findings is that the Neuroticism scale of the Big Five personality dimensions can be used as a screening tool for indicating which players a team would want to recruit and invest time and money in since these players will most likely be capable of progressing to the top level in their sport.

Associations between the dopamine D4 receptor gene polymorphisms and personality traits in elite athletes.

Personality traits and temperament may affect sports performance. Previous studies suggest that dopamine may play an important role in behavior regulation and physical exercise performance. The aim of this study is to determine associations between dopamine D4 receptor gene (DRD4 Ex3) polymorphisms and personality traits (such as neuroticism, extraversion, openness, agreeability and conscientiousness) in elite combat athletes. A total of 302 physically active, unrelated, self-reported Caucasian participants were recruited for this study. The participants consisted of 200 elite male combat athletes and 102 healthy male participants (control group). For personality trait measurements, the NEO Five-Factor Personality Inventory (NEO-FFI) and the State-Trait Anxiety Inventory questionnaires were used. For the genetic assays, blood was collected and all samples were genotyped using the real-time PCR method. A 2 x 3 factorial ANOVA revealed statistically significant differences on the Openness NEO Five Factor Inventory scale for both examined factors, i.e. sport status and genetics DTD4 Ex3. Combat athletes achieved higher scores on the Conscientiousness NEO-FFI scale when compared to controls (7.18 vs 5.98). On the other hand, combat athletes scored lower on the Openness scale in comparison with control group (4.42 vs. 4.63). Subjects with the DRD4 Ex3 s/s genotype had lower results on the openness scale in comparison with participants with the DRD4 Ex3 s/1 genotype (4.01 vs. 4.57) and higher DRD4 Ex3 1/1 genotype (4,01 vs. 3,50). In conclusion, we found an association between the dopamine D4 receptor gene in variable number tandem repeat (VNTR) polymorphisms and athletic status for two NEO-FFI factors: Openness and Conscientiousness. The DRD4 exon 3 polymorphism may be associated with the selected personality traits in combat athletes, thereby modulating athletes’ predisposition to participate in high risk sports.
