Vosloo C, Van Staden W. Agentive steadfastness as trait marker in relation to temperament and character. J Affect Disord 2024; 361:348-355.

Abstract
BACKGROUND Agentive steadfastness was identified as a potential trait marker with which to anticipate prognostically that a patient will persevere steadfastly and take congruent action in facing the demands of living. Taken as an enduring expression of personality, this study investigated agentive steadfastness among adult social media respondents (n = 511) in relation to temperament and character as captured in Cloninger's psychobiological model of personality. METHODS Participants recruited though snowball sampling on social media platforms, applied the 27-item Agentive Steadfastness Index (ASI) and the 240-item Temperament and Character Inventory (TCI-R-240). RESULTS Agentive steadfastness was statistically predicted by the Self-directedness (β = 0.634), Self-transcendence (β = 0.119), Harm Avoidance (β = -0.142) and the Reward Dependence (β = 0.071) scales, accounting for 63.3 % of the variance in one stepwise regression model. In another stepwise model for the TCI-R-240 subscales, the Purposeful (β = 0.359), Anticipatory Worry (β = -0.353), and the Responsibility (β = 0.259) subscales accounted for respectively 56.8 %, 11.2 % and 2.8 % of the variance in ASI scores. LIMITATIONS Results are limited to adult social media respondents who were willing to participate. CONCLUSIONS Agentive steadfastness may serve as a trait marker of well-being and the good prognostic associations that have been established for high self-directedness, low harm avoidance, as well as resilience, and character strengths. It may be assessed clinically to anticipate prognostically the extent to which a patient will persevere steadfastly and take congruent action in facing the demands of living and adversity.

Abstract
The syndrome of apathy has generated increasing interest in recent years as systematic evaluations have revealed its high prevalence and strong negative impact on quality of life across a wide range of neurological and psychiatric conditions. However, although several theoretical models have been proposed to account for various aspects of the condition, understanding of this syndrome is still incomplete. One influential model has proposed that apathy might be described as a quantitative reduction of goal-directed behaviour in comparison to an individual's prior level of functioning. Persistence of activity defined as the capacity to continue with a task - sometimes in the face of setbacks, high levels of difficulty or fatigue - is a crucial but understudied aspect of goal-directed behaviour. Surprisingly, it has not been investigated yet in the context of apathy. Here, we provide an overview of theoretical and experimental aspects of persistence in effort that might assist to develop methods for the investigation of persistence in human behaviour, particularly within the pathologic context of apathy.

Three joint temperament-character configurations account for learning, personality and well-being: normative demographic findings in a representative national population. Front Psychol 2023; 14:1193441.

Abstract
Introduction A common practice in research and clinical practice is to use data considered representative of a target population to compare and understand the personality characteristics of specific groups or specific individuals. To this end, numerous studies have presented normative data for the temperament and character traits outlined in Cloninger's psychobiological model of personality. However, recent genomic evidence demonstrates that human personality is organized as a complex hierarchy that ascends beyond the individual traits to multi-trait profiles that regulate emotional reactivity (temperament profiles) or goals and values (character profiles), and then to three phenotypic networks, which integrate temperament profiles and character profiles, that regulate learning. Given this recent understanding, our aim was to provide a novel and more comprehensive description of personality features at a societal level (using a stratified sample representative of the Portuguese population) by considering personality at its higher levels of complexity. Methods Toward this goal, a stratified sample of 2,443 Portuguese adults responded to the Revised Temperament and Character Inventory (TCI-R). Results We summarize the prevalence of (a) temperament profiles, (b) character profiles, and (c) integrated temperament-character networks within the whole sample, as well as for men vs. women and different age groups separately. Independent of age and education, women were more likely to be capable of resourceful productivity and helpful cooperation combined with being more intuitive, meditative and creative than men. Independent of age and gender, individuals with a degree were also more likely to present these biopsychosocial features. We also found that the organized character profile was most typical of adults in their 40s. Finally, the distribution of personality profiles across age differed as a function of gender: for men the oldest individuals had the most coherent personalities while high personality integration was most prevalent for women in their 30s. Discussion These results have strong implications for research and intervention. In particular, these results are relevant for understanding the epidemiology of interactions between personality, mental health and well-being, including their expressions in a national population as a function of demographic characteristics.

Abstract
Recent genomic, psychological, and developmental research shows that human personality is organized as a complex hierarchy that ascends from individual traits in many specific situations to multi-trait profiles in two domains that regulate emotional reactivity (temperament) or goals and values (character), and finally to three integrated temperament-character networks that regulate learning to maintain well-being in changing conditions. We carried out person-centered analyses of the components of subjective well-being (positive affect, negative affect, and life satisfaction) to personality in both adolescents (N = 1739) and adults (N = 897). Personality was considered at each level of its organization (trait, temperament or character profiles, and joint temperament-character networks). We show for the first time that negative affect and life satisfaction are dependent on the personality network for intentional self-control, whereas positive affect is dependent on the personality network for self-awareness that underlies the human capacities for healthy longevity, creativity, and prosocial values.

Abstract
Objective Personality can influence how we interpret and react to our day-to-day life circumstances. Temperament and character are the primary dimensions of personality, and both are influenced genetically. Temperament represents our emotional core, while character reflects our goals and values as we develop through life. Research shows that where people live, their social, economic, and physical environment can influence attitudes and behaviors, and these have links to variations in personality traits. There are few studies that focus on Australian personality as temperament and character. Using an Australian general population sample, we examined the psychometric properties of the Temperament and Character Inventory (TCIR140) and investigated the associations between TCIR140 traits with both sociodemographic variables and measures of well-being. In addition, we investigated differences in temperament and character between our Australian general population sample and published results of similar studies from other countries. Methods Australians (N = 1,510) completed the Temperament and Character Inventory (TCIR-140), the Positive and Negative Affect Scale and the Satisfaction with Life Scale. Cronbach's alpha and confirmatory factor analysis (CFA) examined the TCIR-140 psychometrics. Correlation analyzes, independent sample t-tests and ANOVA with post-hoc comparisons analyzed the sample. Results Cronbach's alphas were high, ranging from α = 0.78-0.92, and the CFA confirmed two constructs of temperament and character. Females were higher in Harm Avoidance (p < 0.001), Reward Dependence (p < 0.001), and Cooperativeness (p < 0.001) compared to males, who were higher in Self-Directedness (p < 0.001). Age groups showed significant differences among all temperament and character traits (p < 0.001) except for Reward Dependence (p = 0.690). Young adults had the least resilient personality profile and poorest measures of well-being. Correlations with measures of temperament and character, well-being and affect were all in the expected direction. Conclusions Temperament and character are related to indicators of wellbeing and differs by age and sex. This Australian sample demonstrate a temperament that is high in Persistence and a character high in Self-Directedness and Cooperativeness with an overall postive affect and a general satisfaction with life. In comparison to other countries, Australians in this sample differ in levels of several traits, demonstrating a cautious and independent temperament with a character that is cooperative, industrious, and self-reliant. Young-adults in comparison to older groups have a temperament and character profile that is prone to negative emotions and a lower satisfaction with life.

Eley DS, Leung J, Cloninger KM. A longitudinal cohort study observed increasing perfectionism and declining resilience, ambiguity tolerance and calling during medical school which is not explained by student personality. BMC MEDICAL EDUCATION 2022; 22:784. [PMID: 36371205 PMCID: PMC9655808 DOI: 10.1186/s12909-022-03850-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 10/31/2022] [Indexed: 05/19/2023]
Abstract
BACKGROUND The medical degree is a long and challenging program, not just academically, but regarding the expectations engrained in the culture of medical education. The recent proliferation of literature on the poor mental well-being among students suggests a dilemma that often lays the onus on students to improve their health. The link between personality and vulnerability to psychological distress is acknowledged. This longitudinal study looked at personality in 1st-year and changes in levels of certain psychological traits, as proxy indicators of well-being, in 4th-year. We aimed to determine to what extent changes in psychological traits over time may be attributed to personality. METHODS Medical students completed surveys at the start (1st-year: baseline) and finish (4th-year: follow-up) of their medical degree (N = 154). Temperament and character personality, Perfectionism-Concern over mistakes (CoM), Ambiguity Tolerance, Resilience, Calling to medicine, and demographic variables were measured. Paired t-tests compared changes in psychological traits from baseline to follow-up. Linear regression examined whether personality at baseline would predict levels of psychological traits at follow-up. RESULTS The temperament and character profile of the sample was as expected, and congruent with previous studies, which describe a mature personality. Over four years, levels of Perfectionism-CoM significantly increased, while Resilience, Ambiguity Tolerance and Calling to medicine decreased. Harm Avoidance, Persistence, Self-Directedness and Cooperativeness at baseline significantly predicted levels of these traits at follow-up, but effect sizes were weak. Correlations were in the expected direction and weak. CONCLUSIONS Most commencing medical students, including this cohort, have mature personalities with an industrious temperament and an adaptable character. Yet over four years of medicine, Ambiguity Tolerance, Resilience and Calling declined while Perfectionism-CoM, already elevated at baseline, continued to increase to the final year. Of concern is the increased perfectionism that is strongly associated with poor mental health and psychological distress. The findings suggest a closer look at the entirety of the education environment and how its culture, including secondary school and the medical school admissions processes may influence these trends in students. As medical educators we should question why the pathway to medicine places such unhealthy pressure on students who aspire to be doctors.

Abstract
BACKGROUND The temperament and character dimensions of personality appear to be networking structures that interact nonlinearly. Previous studies have attempted to classify temperament and character subtypes using a person-centered approach but have been unable to explore the relationship between the combination of temperament and character and psychopathology patterns in a transdiagnostic sample. The purpose of this study was to examine how symptomatology patterns differ according to individuals' personality profiles, employing a psychobiological model in a transdiagnostic psychiatric sample. METHODS Participants were 1881 patients who visited the psychiatry department of a major medical hospital in Seoul, Korea, and completed both the Temperament Character Inventory (TCI) and the Minnesota Multiphasic Personality Inventory-2-Restructed Form (MMPI-2-RF) as part of their psychological evaluation. We performed two separate latent profile analyses using four temperament and four character indicators of the TCI to identify personality profiles and nine restructured clinical scales of the MMPI-2-RF to identify symptom patterns. RESULTS Five personality classes emerged: "vulnerable-maladaptive," "stable-adaptive," "average," "inhibited-neurotic," and "impulsive-irrational." Moreover, six symptom classes emerged: "non-distressed," "depressed," "emotionally-distressed," "average," "dysfunctional thoughts," and "confused." The personality profiles comprising a combination of rigid temperament and immature character were related to patterns of more severe subjective pain and symptoms. However, profiles with less rigid temperament and less immature character exhibited more diverse symptom patterns. CONCLUSIONS This study examined the relationship between personality profiles and symptomatology patterns, suggesting that understanding patients' personality profiles may be helpful in predicting symptom manifestation and establishing treatment plans.

Abstract
In the current study, common and unique genetic and environmental influences on personality and a broad range of well-being measures were investigated. Data on the Big Five, life satisfaction, quality of life, self-rated health, loneliness, and depression from 14,253 twins and their siblings (age M: 31.82, SD: 14.41, range 16–97) from the Netherlands Twin Register were used in multivariate extended twin models. The best-fitting theoretical model indicated that genetic variance in personality and well-being traits can be decomposed into effects due to one general, common factor ( Mdn: 60%, range 15%–89%), due to personality-specific ( Mdn: 2%, range 0%–78%) and well-being-specific ( Mdn: 12%, range 4%–35%) factors, and trait-specific effects ( Mdn: 18%, range 0%–65%). Significant amounts of non-additive genetic influences on the traits’ (co)variances were found, while no evidence was found for quantitative or qualitative sex differences. Taken together, our study paints a fine-grained, complex picture of common and unique genetic and environmental effects on personality and well-being. Implications for the interpretation of shared variance, inflated phenotypic correlations between traits and future gene finding studies are discussed.

Abstract
Background Personality is the major predictor of people's subjective well-being (i.e., positive affect, negative affect, and life satisfaction). Recent research in countries with high-income and strong self-transcendent values shows that well-being depends on multidimensional configurations of temperament and character traits (i.e., Joint Personality Networks) that regulate the way people learn to adapt their habits to be in accord with their goals and values, rather than individual traits. To evaluate the prevalence and the associations of different Joint Personality (temperament-character) Networks with well-being in a low-income country with weak self-transcendent values, we tested their association in Bulgarian adults, a population known to have strong secular-rationalist values but weak self-transcendent values. Method The sample consisted of 443 individuals from Bulgaria (68.70% females) with a mean age of 34 years (SD = 15.05). Participants self-reported personality (Temperament and Character Inventory), affect (Positive Affect Negative Affect Schedule), and life satisfaction (Satisfaction with Life Scale). The personality scores were used for profiling through latent profile analysis and latent class analysis based on temperament configurations (i.e., Temperament Profiles) of high/low scores of Novelty Seeking (N/n), Harm Avoidance (H/h), Reward Dependence (R/r), and Persistence (P/s); and character configurations (i.e., Character Profiles) of high/low scores of Self-Directedness (S/s), Cooperativeness (C/c), and Self-Transcendence (T/t). Results We found two Temperament Profiles and two Character Profiles that clustered into two distinctive Joint Personality Networks. All individuals in Joint Personality Network 1 had a Reliable (nhRP) Temperament Profile in combination with an Organized (SCt) Character Profile (i.e., a stable temperament and a healthy character configuration). About 71.9% in Joint Personality Network 2 had an Apathetic (sct) Character Profile in combination with Methodical (nHrp) or Reliable (nhRP) Temperament Profiles, while 28.1% had a Methodical (nHrp) Temperament Profile in combination with an Organized (SCt) Character Profile. Few people with high self-expressive values (i.e., high in all three character traits; SCT) were found. Individuals with a Joint Personality Network 1 with strong secular-rationalist values reported higher levels of positive affect and life satisfaction (p < .001), while individuals with a Joint Personality Network 2 reported higher levels of negative affect (p < .001). Conclusions Although a stable temperament and a healthy character were separately important for well-being, it was clear that it was the interaction between such temperament and character configuration that yielded greater levels of subjective well-being. Nevertheless, future research needs to investigate this interaction further to evaluate other cultures with variable configurations of personality traits and values.

Abstract
The aim of this study was to investigate whether loneliness and personality traits correlate with the treatment outcome of methamphetamine use disorder. In this 1-year longitudinal study, a total 106 participants (98 males, 8 females), with a mean age 36.3 ± 9.6 years were enrolled. We measured UCLA Loneliness Scale and Tridimensional Personality Questionnaire at baseline, while craving level at baseline, week 12, 24, 36, and 48. Urinary methamphetamine tests were given 17 times. For the evaluation of the data, multiple linear regression and generalized linear mixed models were used. The baseline results showed lower levels of the harm avoidance trait and higher levels of loneliness were significantly associated with higher craving levels (p=0.04 and 0.04). Moreover, loneliness was not only positively associated with craving levels (B=0.05, p<0.01) but with urinary methamphetamine positive results (B= 0.08, p=0.03) during one-year treatment. The findings suggested that loneliness was associated with poor methamphetamine treatment outcome (greater craving levels and higher proportion of positive methamphetamine urine tests) and lower harm avoidance traits are associated with higher craving levels.

Abstract
OBJECTIVES The relationship between major depressive disorder (MDD) and, especially harm avoidance, self-directedness, and cooperativeness has been determined based on Cloninger's psychobiological personality model; there are not enough studies in the literature on the role of the subdimensions. Therefore, the aim of this study was to compare the patients with MDD and healthy controls in terms of temperament and character traits and especially subdimensions and thus to determine the role and predictive value of temperament and character subdimensions in major depression patients. METHODS The sample of this cross-sectional study consisted of 105 participants, 65 of whom were MDD patients, and 40 healthy controls, who voluntarily agreed to participate in the study. Sociodemographic data form, temperament and character inventory, and Hamilton depression rating scale were administered to the participants. RESULTS Compared with healthy controls, patients with MDD had lower self-directedness (p<0.001), cooperativeness (p=0.017), persistence (p<0.001), self-transcendence (p=0.001), and higher harm avoidance (p<0.001) scores. While there was no significant difference in novelty seeking (p=0.774); it was determined that MDD patients got higher scores in "Impulsiveness" (p=0.013) and lower scores in "Exploratory excitability" (p=0.001) subscales. Reward dependence has been identified as the only personality trait that there was no significant difference between major depression patients and healthy controls (p=0.511). As a result of the logistic regression analysis performed to determine the predictors of temperament and character subdimensions in major depression patients, only three temperament and character traits "Fatigability, Purposefulness, and Spiritual Acceptance" were determined as significant predictors (p<0.001). Fatigability was determined to be a serious risk factor, increasing the probability of MDD 3.6 times (p<0.001); purposefulness and spiritual acceptance were found to be protective personality traits that together reduced the probability of MDD by 0.8 times (p<0.001). CONCLUSION This study shows that the risk of developing MDD is increased in individuals with low self-directedness, cooperativeness, persistence, and self-transcendence profiles, and whereas with prominent Harm avoidance personality traits. Therapeutic interventions, especially considering the temperament and character traits of "Fatigability, Purposefulness, and Spiritual Acceptance" determined in our study, may contribute positively to MDD treatment.

Abstract
The development of compassion for others might be influenced by the social experiences made during childhood and has a genetic component. No research has yet investigated whether the parent-child relationship quality interacts with genetic variation in the oxytocin and dopamine systems in predicting compassion over the life span. In the prospective Young Finns Study (N = 2099, 43.9% men), we examined the interaction between mother-reported emotional warmth and intolerance toward their child assessed in 1980 (age of participants, 3-18 years) and two established genetic risk scores for oxytocin levels and dopamine signaling activity. Dispositional compassion for others was measured with the Temperament and Character Inventory 1997, 2001, and 2012 (age of participants, 20-50 years). We found a gene-environment interaction (p = .031) that remained marginally significant after adjustment for multiple testing. In line with the differential susceptibility hypothesis, only participants who carry alleles associated with low dopamine signaling activity had higher levels of compassion when growing up with emotionally warm parents, whereas they had lower levels of compassion when their parents were emotionally cold. Children's genetic variability in the dopamine system might result in plasticity to early environmental influences that have a long-lasting effect on the development of compassion. However, our findings need replication.

Abstract
Phylogenetic, developmental, and brain-imaging studies suggest that human personality is the integrated expression of three major systems of learning and memory that regulate (1) associative conditioning, (2) intentionality, and (3) self-awareness. We have uncovered largely disjoint sets of genes regulating these dissociable learning processes in different clusters of people with (1) unregulated temperament profiles (i.e., associatively conditioned habits and emotional reactivity), (2) organized character profiles (i.e., intentional self-control of emotional conflicts and goals), and (3) creative character profiles (i.e., self-aware appraisal of values and theories), respectively. However, little is known about how these temperament and character components of personality are jointly organized and develop in an integrated manner. In three large independent genome-wide association studies from Finland, Germany, and Korea, we used a data-driven machine learning method to uncover joint phenotypic networks of temperament and character and also the genetic networks with which they are associated. We found three clusters of similar numbers of people with distinct combinations of temperament and character profiles. Their associated genetic and environmental networks were largely disjoint, and differentially related to distinct forms of learning and memory. Of the 972 genes that mapped to the three phenotypic networks, 72% were unique to a single network. The findings in the Finnish discovery sample were blindly and independently replicated in samples of Germans and Koreans. We conclude that temperament and character are integrated within three disjoint networks that regulate healthy longevity and dissociable systems of learning and memory by nearly disjoint sets of genetic and environmental influences.

Functional Polymorphisms in Oxytocin and Dopamine Pathway Genes and the Development of Dispositional Compassion Over Time: The Young Finns Study. Front Psychol 2021; 12:576346. [PMID: 33897514 PMCID: PMC8060576 DOI: 10.3389/fpsyg.2021.576346] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2020] [Accepted: 03/03/2021] [Indexed: 12/21/2022] Open
Abstract
Background: We define compassion as an enduring disposition that centers upon empathetic concern for another person's suffering and the motivation to act to alleviate it. The contribution of specific candidate genes to the development of dispositional compassion for others is currently unknown. We examine candidate genes in the oxytocin and dopamine signaling pathways. Methods: In a 32-year follow-up of the Young Finns Study (N = 2,130, 44.0% men), we examined with multiple indicators latent growth curve modeling the molecular genetic underpinnings of dispositional compassion for others across the life span. We selected five single nucleotide polymorphisms (SNPs) whose functions are known in humans: rs2268498 (OXTR), rs3796863 (CD38) (related to lower oxytocin levels), rs1800497 (ANKK1/DRD2), rs4680 (COMT), and rs1611115 (DBH) (related to higher dopamine levels). Compassion was measured with Cloninger's Temperament and Character Inventory on three repeated observations spanning 15 years (1997–2012). Differences between gender were tested. Results: We did not find an effect of the five SNPs in oxytocin and dopamine pathway genes on the initial levels of dispositional compassion for others. Individuals who carry one or two copies of the T-allele of DBH rs1611115, however, tend to increase faster in compassion over time than those homozygotes for the C-allele, b = 0.063 (SE = 0.027; p = 0.018). This effect was largely driven by male participants, 0.206 (SE = 0.046; p < 0.001), and was not significant in female participants when analyzed separately. Conclusions: Men who are known to have, on average, lower compassion than women seem to reduce this difference over time if they carry the T-allele of DBH rs1611115. The direction of the association indicates that dopamine signaling activity rather than overall dopamine levels might drive the development of compassion.

Abstract
The multifaceted nature of Alzheimer's disease (AD) and Mild cognitive impairment (MCI) can lead to wide inter-individual differences in disease manifestation in terms of brain pathology and cognition. The lack of understanding of phenotypic diversity in AD arises from a difficulty in understanding the integration of different levels of network organization (i.e. genes, neurons, synapses, anatomical regions, functions) and in inclusion of other information such as neuropsychiatric characteristics, personal history, information regarding general health or subjective cognitive complaints in a coherent model. Non-cognitive factors, such as personality traits and behavioral and psychiatric symptoms, can be informative markers of early disease stage. It is known that personality can affect cognition and behavioral symptoms. The aim of the paper is to review the different types of interactions existing between personality, depression/anxiety, and cognition and cognitive disorders at behavioral and brain/genetic levels.

Abstract
Emerging evidence suggests that temperament may predict childbearing. We examined the association between four temperament traits (novelty seeking, harm avoidance, reward dependence and persistence of the Temperament and Character Inventory) and childbearing over the life course in the population‐based Cardiovascular Risk in Young Finns study (n = 1535; 985 women, 550 men). Temperament was assessed when the participants were aged 20–35 and fertility history from adolescence to adulthood was reported by the participants at age 30–45. Discrete‐time survival analysis modelling indicated that high childbearing probability was predicted by low novelty seeking (standardized OR = 0.92; 95% confidence interval 0.88–0.97), low harm avoidance (OR = 0.90; 0.85–0.95), high reward dependence (OR = 1.09; 1.03–1.15) and low persistence (OR = 0.91; 0.87–0.96) with no sex differences or quadratic effects. These associations grew stronger with increase in numbers of children. The findings were substantially the same in a completely prospective analysis. Adjusting for education did not influence the associations. Despite its negative association with overall childbearing, high novelty seeking increased the probability of having children in participants who were not living with a partner (OR = 1.29; 1.12–1.49). These data provide novel evidence for the role of temperament in influencing childbearing, and suggest possible weak natural selection of temperament traits in contemporary humans.

Abstract
Reinforcement sensitivity theory (RST) is complex, and there are subtle differences between RST and other approach‐avoidance process theories of personality. However, most such theories posit a common biobehavioural mechanism underlying personality which we must therefore strive to understand: differential sensitivity to reinforcing stimuli. Reinforcement sensitivity is widely assessed using questionnaires, but should we treat such measures as (a) a proxy for reinforcement sensitivity itself (i.e. the underlying causes of personality) or (b) trait constructs potentially manifesting out of reinforcement sensitivity (i.e. the ‘surface’ of personality)? Might neuroscience paradigms, such as those I have reviewed in my target paper, provide an advantage over questionnaires in allowing us to move closer to (a), thereby improving both the measurement and our understanding of reinforcement sensitivity? Assuming we can achieve this, how useful is reinforcement sensitivity—and biological perspectives more generally—for explaining personality? These are the major questions raised in the discussion of my target paper, and among the most pertinent issues in this field today. Copyright © 2008 John Wiley & Sons, Ltd.

Abstract
OBJECTIVE Obsessive-compulsive disorder (OCD) is a complex psychiatric disorder with a substantial genetic contribution. While the specific variants underlying OCD's heritability are still unknown, findings from genome-wide association studies (GWAS) corroborate the importance of common SNPs explaining the phenotypic variance in OCD. Investigating associations between the genetic liability for OCD, as reflected by a polygenic risk score (PRS), and potential endophenotypes of the disorder, such as the personality trait harm avoidance, may aid the understanding of functional pathways from genes to diagnostic phenotypes. METHODS We derived PRS for OCD at several P-value thresholds based on the latest Psychiatric Genomics Consortium OCD GWAS (2688 cases, 7037 controls) in an independent sample of OCD patients (n = 180), their unaffected first-degree relatives (n = 108) and healthy controls (n = 200). Using linear regression, we tested whether these PRS are associated with the personality trait harm avoidance. RESULTS Results showed that OCD PRS significantly predicted OCD status, with patients having the highest scores and relatives having intermediate scores. Furthermore, the genetic risk for OCD was associated with harm avoidance across the entire sample, and among OCD patients. As indicated by mediation analyses, harm avoidance mediated the association between the OCD PRS and OCD caseness. These results were observed at multiple P-value thresholds and persisted after the exclusion of patients with a current comorbid major depressive or anxiety disorder. CONCLUSION Our findings support the polygenic nature of OCD and further validate harm avoidance as a candidate endophenotype and diathesis of OCD.

Abstract
Unique pathways to adolescents' co-occurring internalizing/externalizing problems, a severe and common form of psychopathology, remain poorly delineated; this paucity of knowledge impedes the development of personalized interventions. We examined established measures of genetic risk and early childhood temperamental dimensions to clarify potentially distinct pathways to adolescents' co-occurring internalizing/externalizing problems. Participants were drawn from a longitudinal randomized controlled trial of a family-based intervention. The study employed multiple informants and methods, including observer ratings of toddlers' negative affectivity and behavioral inhibition, and primary caregiver ratings of toddlers' inhibitory control; internalizing and aggression polygenic risk scores (PRS) based on prior meta-genome-wide association studies (GWAS); and parents' and teachers' reports of adolescents' internalizing and externalizing problems. Higher levels of the aggression PRS indirectly predicted primary caregiver- and teacher-reported co-occurring problems relative to all other groups through greater early childhood negative affectivity. Lower levels of the aggression PRS and higher levels of the internalizing PRS indirectly predicted co-occurring problems relative to the externalizing "only" and low problem groups (primary caregivers only) through greater early childhood behavioral inhibition. Findings suggest two different genetic pathways to co-occurring problems that could lead to distinct prevention and intervention efforts. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Abstract
Human personality is 30-60% heritable according to twin and adoption studies. Hundreds of genetic variants are expected to influence its complex development, but few have been identified. We used a machine learning method for genome-wide association studies (GWAS) to uncover complex genotypic-phenotypic networks and environmental interactions. The Temperament and Character Inventory (TCI) measured the self-regulatory components of personality critical for health (i.e., the character traits of self-directedness, cooperativeness, and self-transcendence). In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified five clusters of people with distinct profiles of character traits regardless of genotype. Third, we found 42 SNP sets that identified 727 gene loci and were significantly associated with one or more of the character profiles. Each character profile was related to different SNP sets with distinct molecular processes and neuronal functions. Environmental influences measured in childhood and adulthood had small but significant effects. We confirmed the replicability of 95% of the 42 SNP sets in healthy Korean and German samples, as well as their associations with character. The identified SNPs explained nearly all the heritability expected for character in each sample (50 to 58%). We conclude that self-regulatory personality traits are strongly influenced by organized interactions among more than 700 genes despite variable cultures and environments. These gene sets modulate specific molecular processes in brain for intentional goal-setting, self-reflection, empathy, and episodic learning and memory.

Abstract
Recent genome-wide association studies (GWAS) have shown that temperament is strongly influenced by more than 700 genes that modulate associative conditioning by molecular processes for synaptic plasticity and long-term learning and memory. The results were replicated in three independent samples despite variable cultures and environments. The identified genes were enriched in pathways activated by behavioral conditioning in animals, including the two major molecular pathways for response to extracellular stimuli, the Ras-MEK-ERK and the PI3K-AKT-mTOR cascades. These pathways are activated by a wide variety of physiological and psychosocial stimuli that vary in positive and negative valence and in consequences for health and survival. Changes in these pathways are orchestrated to maintain cellular homeostasis despite changing conditions by modulating temperament and its circadian and seasonal rhythms. In this review we first consider traditional concepts of temperament in relation to the new genetic findings by examining the partial overlap of alternative measures of temperament. Then we propose a definition of temperament as the disposition of a person to learn how to behave, react emotionally, and form attachments automatically by associative conditioning. This definition provides necessary and sufficient criteria to distinguish temperament from other aspects of personality that become integrated with it across the life span. We describe the effects of specific stimuli on the molecular processes underlying temperament from functional, developmental, and evolutionary perspectives. Our new knowledge can improve communication among investigators, increase the power and efficacy of clinical trials, and improve the effectiveness of treatment of personality and its disorders.

Abstract
PURPOSE The investigation aimed to explore the association between personality traits, stressful life events, quality of life on anthropometric characteristics (waist/height ratio and percentage of visceral fat). METHOD A total of 227 participants took part in this cross-sectional study. Participants completed the Social Readjustment Rating Scale (SRRS), Temperament and Character Inventory-Revised, Type-D Scale (DS-14), EuroQol Group 5-Dimension Self-Report Questionnaire (EQ-5D), and demographic questionnaire. Two anthropometric parameters were measured: Waist/height ratio and Percentage of the visceral fat. RESULTS The average age of participants was 39.6±12.9 years, 60.4% women. The 41.8% of participants were overweight or obese. Regression analysis found a significant link between Harm-avoidance and EQ-5D visual analog scale (VAS) with Waist/height ratio in women and Reward dependence and Cooperativeness with Waist/height ratio in men. In regression analysis, the score of life events (SRRS) has statistically significant linked to Percentage of the visceral fat in women. The regression analysis also found a significant link between Novelty seeking, DS14, Negative affectivity, and EQ-5D VAS with Percentage of the visceral fat in women. CONCLUSION Significant associations between live events, personality traits, and body anthropometric measures were recognized. The differences were recognized between women and men. Outcomes propose some promising tools by which personality factors may influence overweight and obesity.

Abstract
The “extreme sports” of mountaineering and BASE Jumping are growing in popularity and are associated with significant risk of injury and death. In recent years there have also been increasing numbers of reports of reckless disregard and selfishness in the pursuit of mountaineering goals, including severe environmental degradation. Extant research has focused predominantly on personality variables that contribute to engagement, participation, and stress responsivity in these extreme sports. The Temperament and Character Inventory (TCI) provides a comprehensive account of personality traits, measuring seven dimensions of personality that are moderately heritable and associated with distinct brain networks and psychological characteristics. One of these traits is Self-Transcendence, which is associated with spiritual ideas and experiences, such as searching for something elevated and greater than one's individual self. High Self-Transcendence can motivate people to act altruistically even if that requires personal sacrifices and hardship. This article draws on the extant research literature, which has consistently found that despite substantial heterogeneity in their individual personality profiles, mountaineers, and BASE jumpers are adventurous in temperament and highly self-controlled and organized in character. Between 75 and 85% of the character configurations observed in these populations are associated with low Self-Transcendence. The purpose of this paper is to consider the role of Self-Transcendence and its effect on individual personality profiles of extreme athletes, in particular in moderating potentially self- destructive, and regressive ethical and moral behaviors in mountaineering and BASE jumping.

Abstract
There is fundamental doubt about whether the natural unit of measurement for temperament and personality corresponds to single traits or to multi-trait profiles that describe the functioning of a whole person. Biogenetic researchers of temperament usually assume they need to focus on individual traits that differ between individuals. Recent research indicates that a shift of emphasis to understand processes within the individual is crucial for identifying the natural building blocks of temperament. Evolution and development operate on adaptation of whole organisms or persons, not on individual traits or categories. Adaptive functioning generally depends on feedback among many variable processes in ways that are characteristic of complex adaptive systems, not machines with separate parts. Advanced methods of unsupervised machine learning can now be applied to genome-wide association studies and brain imaging in order to uncover the genotypic-phenotypic architecture of traits like temperament, which are strongly influenced by complex interactions, such as genetic epistasis, pleiotropy and gene-environment interactions. We have found that the heritability of temperament can be nearly fully explained by a large number of genetic variants that are unique for multi-trait profiles, not single traits. The implications of this finding for research design and precision medicine are discussed.This article is part of the theme issue 'Diverse perspectives on diversity: multi-disciplinary approaches to taxonomies of individual differences'.

Abstract
Despite various advances in the study of the neurobiological underpinnings of personality traits, the specific neural correlates associated with character and temperament traits are not yet fully understood. Therefore, this study aims to fill this gap by exploring the biochemical basis of personality, which is explored with the temperament and character inventory (TCI), during brain development in a sample of adolescents. Twenty-six healthy adolescents (aged between 13 and 21 years; 17 males and 9 females) with behavioral and emotional problems underwent a TCI evaluation and a 3T single-voxel proton magnetic resonance spectroscopy (1H MRS) acquisition of the anterior cingulate cortex (ACC). Absolute metabolite levels were estimated using LCModel: significant correlations between metabolite levels and selective TCI scales were identified. Specifically, phosphocreatine plus creatine (PCr+Cre) significantly correlated with self-directedness, positively, and with a self-transcendence (ST), negatively, while glycerophosphocholine plus phosphocholine (GPC+PC) and myo-inositol negatively correlated with ST. To the best of our knowledge, this is the first study reporting associations of brain metabolites with personality traits in adolescents. Therefore, our results represent a step forward for personality neuroscience within the study of biochemical systems and brain structures.

Abstract
Objective A putative relationship between markers for the serotonin system and the personality scale self-transcendence (ST) and its subscale spiritual acceptance (SA) has been demonstrated in a previous PET study of 5-HT1A receptor binding in healthy control subjects. The results could however not be replicated in a subsequent PET study at an independent centre. In this study, we performed a replication of our original study in a larger sample using Bayesian hypothesis testing to evaluate relative evidence both for and against this hypothesis. Methods Regional 5-HT1A receptor binding potential (BPND) was examined in 50 healthy male subjects using PET with the radioligand [11C]WAY100635. 5-HT1Aavailability was calculated using the simplified reference tissue model (SRTM) yielding regional BPND. ST and SA were measured using the Temperament and Character Inventory (TCI) questionnaire. Correlations between ST/SA scores and 5-HT1ABPND in frontal cortex, hippocampus and raphe nuclei were examined by calculation of default correlation Bayes factors (BFs) and replication BFs. Results There were no significant correlations between 5-HT1A receptor binding and ST/SA scores. Rather, five of six replication BFs provided moderate to strong evidence for no association between 5-HT1A availability and ST/SA, while the remaining BF provided only weak evidence. Conclusion We could not replicate our previous findings of an association between 5-HT1A availability and the personality trait ST/SA. Rather, the Bayesian analysis provided evidence for a lack of correlation. Further research should focus on whether other components of the serotonin system may be related to ST or SA. This study also illustrates how Bayesian hypothesis testing allows for greater flexibility and more informative conclusions than traditional p-values, suggesting that this approach may be advantageous for analysis of molecular imaging data.

Abstract
BACKGROUND Several conditions presenting with abdominal pain are associated with specific personality factors although it is unclear if this is true also in emergency clinic settings. OBJECTIVE To study personality factors among patients with acute abdominal pain in an emergency ward. METHODS Consecutive patients (N = 165) with abdominal symptoms at an emergency clinic were administrated the Temperament and Character Inventory (TCI). Three main groups were identified; specific abdominal diagnoses, (N = 77), non-specific abdominal pain, (N = 67) and organic dyspepsia (N = 21). TCI results were compared between clinical groups and a control group (N = 122). RESULTS As compared to individuals with specific abdominal diagnoses and controls, those with organic dyspepsia were significantly more anxious (harm avoidance), (p = 0.003), and had lower ability to cooperate (cooperativeness) (p = 0.048 and p = 0.004 respectively). They were also significantly more unpretentious (self-transcendence) compared to individuals with specific abdominal diagnoses (p = 0.048), non-specific abdominal pain (p = 0.012) and controls (p = 0.004) and evidenced less mature character (sum of self-directedness and cooperativeness) compared to those with specific abdominal diagnoses and controls (p = 0.003). CONCLUSION Individuals seeking care at an emergency clinic with organic dyspepsia showed a distinguishable pattern of personality features that distinguished them from the other comparison groups. Therefore an evaluation of personality factors may add a new dimension to the diagnostic investigation in the emergency care of abdominal pain and contribute to the optimization of the treatment of organic dyspepsia.

Abstract
BACKGROUND Temperament is theorized to be an important factor contributing to the development of alcohol use disorder, but longitudinal studies on how temperament is related to alcohol use among general population in midlife are scarce. Our aims were to investigate potentially reciprocal associations between temperament and changes in alcohol use from age 31 to 46 using prospective birth cohort data. METHOD Within the Northern Finland Birth Cohort 1966, alcohol use and temperament were studied at ages 31 and 46. Participants (N = 5,274) were classified into moderate users, abstainers and heavy users based on their mean alcohol use (g/d). Additionally, participants were categorized as steady users, reducers, or increasers. Multinomial regression analyses were conducted with Cloninger's Temperament and Character Inventory (TCI) scores as factors influencing alcohol use using moderate and stable users as reference groups. Reciprocity of relations was assessed with cross-lagged structural equation modeling. RESULTS Temperament and alcohol use are rather stable in midlife. Novelty seeking (NS) predicted heavy use (OR = 1.4; CI: 1.3 to 1.6 for men, OR = 1.3; CI: 1.1 to 1.5 for women) and increasing use (OR = 1.2; CI: 1.1 to 1.4 for men, OR = 1.1; CI: 1.0 to 1.3 for women), whereas low NS predicted abstaining among women (OR = 0.7; CI: 0.6 to 0.8). High harm avoidance (HA) predicted abstaining (OR = 1.3; CI: 1.1 to 1.5) for men. Low persistence (P) among men predicted both abstaining (OR = 0.9; CI: 0.7 to 0.98) and heavy use (OR = 0.9; CI: 0.8 to 0.98). Among women, low reward dependence (RD) predicted heavy use (OR = 0.8; CI: 0.7 to 0.9). Among TCI scores, only NS predicted increasing use in the cross-lagged models. CONCLUSIONS Temperament has an impact on alcohol use in midlife. Of the TCI dimensions, only NS seems to predispose to increased alcohol use and problem use throughout life. Additionally, RD among women and P among men are significant factors from a life-course perspective. Our results did not support Cloninger's theory on type I alcoholism, as HA showed no relation to problematic alcohol use in midlife.

Abstract
The elusive relationship between the mental domain and the physical brain, known as the mind-body problem, is still a hot topic of discussion among philosophers and neuroscientists. Rather than solving this problem, our pilot study addresses the question as to whether personality features could influence intuitions of the mind-body problem, or more precisely, whether it is possible to identify a person’s intuitive inclinations toward dualism or materialism and their inclinations toward reduction of the mind to the brain. For the purposes of this pilot study, we developed a questionnaire, which employed several theories of analytic philosophy of the mind, in order to determine which category the participants would belong to. These main categories were dualism, non-reductive materialism and reductive materialism. To test whether personality features affect preferences for these categories, the participants were investigated by Cloninger’s Temperament and Character Inventory (TCI). We found significant differences in the self-transcendence dimension of the TCI between participants who were evaluated as dualists and those who were assessed as reductive materialists. Our data show that the personality dimension of self-transcendence correlates with intuitive inclination toward reductive materialism or dualism. In addition, our results suggest that ideas, theories, and hypothetical solutions of the mind-body problem and possibly even conclusions, acceptance, and disputations of thought experiments of philosophy of the mind can be biased by personality traits. This fact should be taken into account in future discussions of the philosophy of the mind and may also be important for empirical research and an empirical understanding of the mind.

Abstract
Phenotypic heterogeneity is a major barrier to understanding the genetic architecture underlying schizophrenia. Incorporating endophenotypes is one way to reduce heterogeneity and facilitate more powerful genetic analysis. Candidate endophenotypes require systematic assessment against endophenotype criteria, and a ranking of their potential utility for genetic analysis. In this study we assess 20 cognitive and personality measures in a sample of 127 families with at least 2 cases of schizophrenia per family (n = 535) plus a set of 30 control families (n = 121) against 4 endophenotype criteria: (a) be associated with the illness but not be a part of its diagnosis, (b) be heritable, (c) co-segregate with the illness in families, and (d) be found in unaffected relatives at a higher rate than in the general population. The endophenotype ranking score (endophenotype ranking variable [ERV]) was used to rank candidate endophenotypes based on their heritability and genetic correlation with schizophrenia. Finally, we used factor analysis to explore latent factors underlying the cognitive and personality measures. Evidence for personality measures as endophenotypes was at least equivalent to that of the cognitive measures. Factor analysis indicated that personality and cognitive traits contribute to independent latent dimensions. The results suggest for this first time that a number of cognitive and personality measures are independent and informative endophenotypes. Use of these endophenotypes in genetic studies will likely improve power and facilitate novel aetiological insights.

Abstract
We studied the pattern of personality development in a longitudinal population-based sample of 752 American adolescents. Personality was assessed reliably with the Junior Temperament and Character Inventory at 12, 14, and 16 years of age. The rank-order stability of Junior Temperament and Character Inventory traits from age 12 to 16 was moderate (r = .35). Hierarchical linear modeling of between-group variance due to gender and within-group variance due to age indicated that harm avoidance and persistence decreased whereas self-directedness and cooperativeness increased from age 12 to 16. Novelty seeking, reward dependence, and self-transcendence increased from age 12 to 14 and then decreased. This biphasic pattern suggests that prior to age 14 teens became more emancipated from adult authorities while identifying more with the emergent norms of their peers, and after age 14 their created identity was internalized. Girls were more self-directed and cooperative than boys and maintained this advantage from age 12 to 16. Dependability of temperament at age 16 was mainly predicted by the same traits at earlier ages. In contrast, maturity of character at age 16 was predicted by both temperament and character at earlier ages. We conclude that character develops rapidly in adolescence to self-regulate temperament in accord with personally valued goals shaped by peers.

Abstract
Personality traits are the relatively enduring patterns of thoughts, feelings and behaviors that reflect the tendency to respond in certain ways under certain circumstances. Twin and family studies have showed that personality traits are moderately heritable, and can predict various lifetime outcomes, including psychopathology. The Research Domain Criteria characterizes psychiatric diseases as extremes of normal tendencies, including specific personality traits. This implies that heritable variation in personality traits, such as neuroticism, would share a common genetic basis with psychiatric diseases, such as major depressive disorder. Despite considerable efforts over the past several decades, the genetic variants that influence personality are only beginning to be identified. We review these recent and increasingly rapid developments, which focus on the assessment of personality via several commonly used personality questionnaires in healthy human subjects. Study designs covered include twin, linkage, candidate gene association studies, genome-wide association studies and polygenic analyses. Findings from genetic studies of personality have furthered our understanding about the genetic etiology of personality, which, like neuropsychiatric diseases themselves, is highly polygenic. Polygenic analyses have showed genetic correlations between personality and psychopathology, confirming that genetic studies of personality can help to elucidate the etiology of several neuropsychiatric diseases.

Abstract
Conduct disorder (CD) and anxiety disorders (ADs) are often comorbid and both are characterized by hyper-sensitivity to threat, and reduced structural and functional connectivity between the amygdala and orbitofrontal cortex (OFC). Previous studies of CD have not taken account of ADs nor directly compared connectivity in the two disorders. We examined three groups of young women: 23 presenting CD and lifetime AD; 30 presenting lifetime AD and not CD; and 17 with neither disorder (ND). Participants completed clinical assessments and diffusion-weighted and resting-state functional MRI scans. The uncinate fasciculus was reconstructed using tractography and manual dissection, and structural measures extracted. Correlations of resting-state activity between amygdala and OFC seeds were computed. The CD + AD and AD groups showed similarly reduced structural integrity of the left uncinate compared to ND, even after adjusting for IQ, psychiatric comorbidity, and childhood maltreatment. Uncinate integrity was associated with harm avoidance traits among AD-only women, and with the interaction of poor anger control and anxiety symptoms among CD + AD women. Groups did not differ in functional connectivity. Reduced uncinate integrity observed in CD + AD and AD-only women may reflect deficient emotion regulation in response to threat, common to both disorders, while other neural mechanisms determine the behavioral response.

Abstract
Genetic and environmental interactive influences on predisposition to develop alcohol use disorder (AUD) account for the high heterogeneity among AUD patients and make research on the risk and resiliency factors complicated. Several attempts have been made to identify the genetic basis of AUD; however, only few genetic polymorphisms have consistently been associated with AUD. Intermediate phenotypes are expected to be in-between proxies of basic neuronal biological processes and nosological symptoms of AUD. Personality is likely to be a top candidate intermediate phenotype for the dissection of the genetic underpinnings of different subtypes of AUD. To date, 38 studies have investigated personality traits, commonly assessed by the Cloninger's Tridimensional Personality Questionnaire (TPQ) or Temperament and Character Inventory (TCI), in relation to polymorphisms of candidate genes of neurotransmitter systems in alcohol-dependent patients. Particular attention has been given to the functional polymorphism of the serotonin transporter gene (5-HTTLPR), however, leading to contradictory results, whereas results with polymorphisms in other candidate monoaminergic genes (e.g., tryptophan hydroxylase, serotonin receptors, monoamine oxidases, dopamine receptors and transporter) are sparse. Only one genome-wide association study has been performed so far and identified the ABLIM1 gene of relevance for novelty seeking, harm avoidance and reward dependence in alcohol-dependent patients. Studies investigating genetic factors together with personality could help to define more homogenous subgroups of AUD patients and facilitate treatment strategies. This review also urges the scientific community to combine genetic data with psychobiological and environmental data to further dissect the link between personality and AUD.

Abstract
BACKGROUND AND AIM Patients who have schizophrenia are more prone to suicidal behavior than the general population. This study aimed to find connections between suicidality and self-stigma, hope, and personality traits in patients with schizophrenia. METHODS Forty-eight stabilized outpatients with schizophrenia attended this cross-sectional study. Patients were diagnosed by the Mini International Neuropsychiatric Interview (MINI) using the ICD-10 research diagnostic criteria. The assessments included Positive and Negative Syndrome Scale, objective and subjective Clinical Global Impression, Liebowitz Social Anxiety Scale, Beck Depression Inventory-second edition, Internalized Stigma of Mental Illness, the Temperament and Character Inventory, and Adult Dispositional Hope Scale. RESULTS The individual rate of suicidality (suicidal index from MINI) strongly positively correlated with self-stigma, level of depression, social anxiety, and harm-avoidance, and negatively correlated with hope, self-directedness, and stigma resistance. CONCLUSION Individuals with additional symptoms of depression, social anxiety, trait-like anxiety, and self-stigma should be carefully monitored for suicidal ideation. On the opposite side, patients with sufficient hope, self-esteem, and goal-directed attitudes are less likely to have suicidal thoughts and may potentially be role models in group rehabilitation programs, motivating more distressed colleagues and showing them ways to cope.

Abstract
BACKGROUND Food addiction has been widely researched in past years. However, there is a debate on the mechanisms underlying addictive eating and a better understanding of the processes associated to these behaviors is needed. Previous studies have found characteristic psychological correlates of food addiction, such as high negative urgency, emotion regulation difficulties and low self-directedness, in different samples of adults with addictive eating patterns. Still, it seems difficult to disentangle effects independent from general eating disorder psychopathology. Therefore, this study aimed to test a comprehensive model under control of eating disorder severity, in order to find independent predictors of food addiction. METHODS 315 patients with eating disorder diagnoses on the binge-eating spectrum were assessed in personality, emotion regulation, negative urgency, eating disorder symptomatology, and food addiction by self-report. Hypothesis-driven structural equation modeling was conducted to test the comprehensive model. RESULTS The only independent predictor found for food addiction was negative urgency, while self-directedness and emotion regulation predicted negative urgency and were highly related to eating disorder symptomatology, but not to food addiction. CONCLUSIONS Altogether the model suggests that low self-directedness and difficulties in emotion regulation are related to higher eating disorder symptomatology in general. Those patients who, in addition to these traits, tend to act impulsively when in negative mood states, are at risk for developing addictive eating patterns. Urgency-based treatments are therefore recommended for this subgroup of patients.

Abstract
OBJECTIVE The etiology of obsessive-compulsive disorder (OCD) is assumed to involve interactions between genetically determined vulnerability factors and significant environmental features. Here, we aim to investigate how the personality trait harm avoidance and the experience of childhood adversities contribute to OCD. METHOD A total of 169 patients with OCD, 157 healthy comparison subjects, and 57 unaffected first-degree relatives of patients with OCD participated in the study. Harm avoidance was assessed using the Temperament and Character Inventory, and the severity of childhood adversities was measured with the Childhood Trauma Questionnaire. RESULTS Both patients with OCD and relatives showed elevated levels of harm avoidance compared to controls. Furthermore, patients exhibited significantly higher scores than relatives. This linear pattern was observed throughout all subscales of harm avoidance, and remained stable after controlling for the severity of depressive and obsessive-compulsive symptoms. With regard to childhood adversities, patients with OCD reported higher levels than relatives and controls. CONCLUSION Our results provide further evidence for a diathesis-stress model of OCD. While patients and unaffected relatives share elevated levels of harm avoidance, supporting the role of harm avoidance as an endophenotype of OCD, a heightened severity of childhood adversity was only observed in patients. The assumed biological underpinnings of these findings are discussed.

Abstract
OBJECTIVE The purpose of the study was to explore whether the comorbidity of social phobia affects symptoms severity, positive and negative symptoms, self-stigma, hope, and quality of life in patients with schizophrenia spectrum disorders. METHODS This is a cross-sectional study in which all participants completed the Internalized Stigma of Mental Illness (ISMI) scale, Adult Dispositional Hope Scale (ADHS), Liebowitz Social Anxiety Scale (LSAS), Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II), Positive and Negative Syndrome Scale (PANSS), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), Temperament and Character Inventory - Revised (TCI-R), and the demographic questionnaire. The disorder severity was assessed both by a psychiatrist (Clinical Global Impression Severity - the objective version [objCGI-S] scale) and by the patients (Clinical Global Impression Severity - the subjective version [subjCGI-S] scale). The patients were in a stabilized state that did not require changes in the treatment. Diagnosis of schizophrenia, schizoaffective disorder, or delusional disorder was determined according to the International Classification of Diseases 10th Revision (ICD-10) research criteria. A structured interview by Mini International Neuropsychiatric Interview was used to confirm the diagnosis. RESULTS The study included 61 patients of both genders. Clinically, the patients with comorbid social phobia had the earlier onset of the illness, more severe current psychopathology, more intense anxiety (general and social), and higher severity of depressive symptoms. The patients with comorbid social phobia showed the significantly lower quality of life compared to the patients without this comorbidity. The patients with comorbid social phobia also had a statistically lower mean level of hope and experienced a higher rate of the self-stigma. They also exhibited higher average scores of personality trait harm avoidance (HA) and a lower score of personality trait self-directedness (SD). CONCLUSION The study demonstrated differences in demographic factors, the severity of the disorder, self-stigma, hope, HA, and SD between patients with schizophrenia spectrum disorders with and without comorbid social phobia.

Abstract
GOALS The aim of this study was to explore the quality of life, self-stigma, personality traits, and hope in patients with schizophrenia spectrum disorders. PATIENTS AND METHODS A total of 52 outpatients participated in this cross-sectional study. The attending psychiatrist assessed each patient with Mini International Neuropsychiatric Interview (MINI). The patients then completed Quality of Life Satisfaction and Enjoyment Questionnaire (Q-LES-Q), Internalized Stigma of Mental Illness (ISMI) Scale, Temperament and Character Inventory - Revised (TCI-R), Adult Dispositional Hope Scale (ADHS), Drug Attitude Inventory 10 (DAI-10), and Liebowitz Social Anxiety Scale (LSAS)-Self-report. The psychiatrist evaluated Clinical Global Impression Severity - the objective version (objCGI-S), and the patients completed the Clinical Global Impression Severity - the subjective version (subjCGI-S). Each participant also completed Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI). RESULTS The quality of life was significantly higher in employed patients and individuals with higher hope, self-directedness (SD), and persistence (PS). The quality of life was lower among patients with higher number of psychiatric hospitalizations, those with higher severity of the disorder, and individuals who were taking higher doses of antipsychotics. Patients with more pronounced symptoms of depression, anxiety, and social anxiety had a lower quality of life. Finally, the quality of life was lower among individuals with higher harm avoidance (HA) and self-stigmatization (ISMI). Backward stepwise regression was applied to identify the most significant factors connected to self-stigma. The regression analysis showed that occupation, level of depression (BDI-II), attitude to using medication (DAI-10), social anxiety (LSAS), and antipsychotic index were the most relevant factors associated with lower quality of life. CONCLUSION Detection of the quality of life in the context of personality traits, hope, self-stigma, and demographic and clinical factors may be an important part of the assessment of the patient with schizophrenia.

Normative data and effects of age and gender on temperament and character dimensions across the lifespan in an Italian population: A cross-sectional validation study. J Affect Disord 2016; 204:83-91. [PMID: 27341424 DOI: 10.1016/j.jad.2016.06.014] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2015] [Revised: 05/09/2016] [Accepted: 06/05/2016] [Indexed: 01/18/2023]
Abstract
BACKGROUND The short version of the Temperament and Character Inventory (TCI-125) has been employed for the study of personality traits in both clinical and normal populations. However, to the best of our knowledge, no studies explored the psychometric properties of this instrument in healthy individuals across the lifespan. We here provide the Italian normative data and present the personality features according to age and gender in a sample of healthy individuals. METHODS A cross-sectional study was carried out in a total of 1430 Italian healthy individuals ranging from 13 to 67 years (59.3% females). We evaluated the factorial model of the TCI-125, explored the internal consistency of the scales and carried out univariate analyses of variance for the investigation of age and gender differences in temperament and character dimensions. RESULTS Confirmatory factor analysis only partially confirmed the factor structure, with some Reward Dependence, Self-Directedness, and Cooperativeness items showing poor fit. Overall we found acceptable internal consistencies for all the dimensions of the TCI-125 across all age groups, except for Reward Dependence, Persistence, and Novelty Seeking, which showed unsatisfactory internal consistency in younger age groups. Furthermore, we found significant age differences in most temperament and all character dimensions. Finally, in specific age groups we also observed significantly lower scores in males compared to females in Harm Avoidance, Reward Dependence and all character dimensions except for Self-Directedness, on which males scored higher than females. CONCLUSIONS Although this study only partially confirmed the factor structure of the TCI-125 and suggested limited homogeneity for some temperament scales, overall our results supported the reliability of the TCI-125, which can therefore be considered a useful tool for exploring personality traits in both clinical and normal samples. Moreover, this study suggested the need of using this instrument with caution in adolescents.

Stress reactivity and personality in extreme sport athletes: The psychobiology of BASE jumpers. Physiol Behav 2016; 167:289-297. [PMID: 27693575 DOI: 10.1016/j.physbeh.2016.09.025] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2016] [Revised: 09/13/2016] [Accepted: 09/27/2016] [Indexed: 11/23/2022]
Abstract
This is the first report of the psychobiology of stress in BASE jumpers, one of the most dangerous forms of extreme sport. We tested the hypotheses that indicators of emotional style (temperament) predict salivary cortisol reactivity, whereas indicators of intentional goal-setting (persistence and character) predict salivary alpha-amylase reactivity during BASE jumping. Ninety-eight subjects completed the Temperament and Character Inventory (TCI) the day before the jump, and 77 also gave salivary samples at baseline, pre-jump on the bridge over the New River Gorge, and post-jump upon landing. Overall BASE jumpers are highly resilient individuals who are highly self-directed, persistent, and risk-taking, but they are heterogeneous in their motives and stress reactivity in the Hypothalamic-Pituitary-Adrenal (HPA) stress system (cortisol reactivity) and the sympathetic arousal system (alpha-amylase reactivity). Three classes of jumpers were identified using latent class analysis based on their personality profiles, prior jumping experience, and levels of cortisol and alpha-amylase at all three time points. "Masterful" jumpers (class 1) had a strong sense of self-directedness and mastery, extensive prior experience, and had little alpha-amylase reactivity and average cortisol reactivity. "Trustful" jumpers (class 2) were highly cooperative and trustful individuals who had little cortisol reactivity coincident with the social support they experienced prior to jumping. "Courageous" jumpers (class 3) were determined despite anxiety and inexperience, and they had high sympathetic reactivity but average cortisol activation. We conclude that trusting social attachment (Reward Dependence) and not jumping experience predicted low cortisol reactivity, whereas persistence (determination) and not jumping experience predicted high alpha-amylase reactivity.

Association between neurological soft signs, temperament and character in patients with schizophrenia and non-psychotic relatives. PeerJ 2016; 4:e1651.

Abstract
The heritability of schizophrenia and most personality traits has been well established, but the role of personality in susceptibility to schizophrenia remains uncertain. The aim of this study was to test for an association between personality traits and Neurological Soft Signs (NSS), a well-known biological marker of schizophrenia, in non-psychotic relatives of patients with schizophrenia. For this purpose, we evaluated the NSS scale and personality measured by the Temperament and Character inventory (TCI-R) in three groups of subjects: 29 patients with schizophrenia, 24 unaffected relatives and 37 controls. The results showed that patients with schizophrenia were more asocial (higher harm avoidance and lower reward dependence), more perseverative (higher persistence), and more schizotypal (lower self-directedness and cooperativeness, higher self-transcendence). The unaffected relatives showed higher harm avoidance, lower self-directedness and cooperativeness than the healthy controls. Higher NSS scores and sub-scores were found in patients and non-psychotic relatives compared with the controls. Among all the patients, total NSS scores were positively correlated with harm avoidance but negatively correlated with novelty seeking and persistence. Total NSS were also correlated with low scores on self-directedness and cooperativeness, which are indicators of personality disorder. Our results show that susceptibility to NSS and to schizophrenia are both related to individual differences in the temperament and character features in non-psychotic relatives of patients with schizophrenia. High harm avoidance, low persistence, low self-directedness and low cooperativeness contribute to both the risk of NSS and schizophrenia. These findings highlight the value of using both assessments to study high risk populations.
