The role of noncognitive skills in educational mismatch: evidence from China

PurposeThe purpose of this study is to investigate the effect of noncognitive skills on educational mismatch in the context of China and to further explore the potential mechanisms concerning how noncognitive skills determine mismatch outcomes.Design/methodology/approachThis paper uses the Chinese Family Panel Survey of 2018, which provides the Big Five Personality Inventory to assess respondents' noncognitive skills and contains information on educational mismatch. The authors estimate the effects of noncognitive skills on educational mismatch by means of a probit model. Additionally, the correlated random effects (CRE) model and instrumental variable (IV) approach have also been exploited in the robust checks.FindingsThe findings show that the composite score of noncognitive skills reduces the probability of being overeducated and, conversely, increases the likelihood of being undereducated. When distinguishing the effects of different personality traits, the authors find significantly negative effects of agreeableness and openness on overeducation and a positive effect of openness on undereducation. With regard to heterogeneous analysis, the effects of noncognitive skills on educational mismatch exist mostly among white-collar employees and employees with fewer than 5 years of work experience. Finally, the authors provide two likely mechanisms related to job search effort and social capital, followed by the presentation of supporting evidence.Practical implicationsThe results of this paper underline the importance of noncognitive skills in raising the quality of jobs that individuals can obtain. This suggests that the development of noncognitive skills should be encouraged to be integrated into formal education systems and social job training programs in China.Originality/valueDespite a growing interest in its consequences in the labor market, the role of noncognitive skills in determining educational mismatch has rarely been discussed in developing countries. This study provides the first evidence regarding the effects of noncognitive skills on education mismatch in China. It contributes to the research on noncognitive skills' labor market outcomes and enhances the understanding of the factors driving educational mismatch.

The Personality Inventory for DSM-5-Brief Form (PID-5-BF): Psychometric indicators in a Brazilian community sample

Objective: To investigate psychometric properties (internal structure, convergent/discriminant validity, internal consistency, and test-retest) of the Personality Inventory for DSM-5-Brief Form (PID-5-BF) in a Brazilian community sample. Method: This is a study with a psychometric design. A sample of 527 adults from the general population (69.9% women; 33.5 ± 14.0 years; 74.0% ≥ 12 years education) responded to the instrument online after the study was disseminated on social networks and to the researchers’ contacts. The NEO-PI-R and sociodemographic questionnaire were applied besides the PID-5-BF, and a retest was applied 15-30 days after the initial assessment for reliability assessment. Data were analyzed using statistical techniques (IBM SPSS19 and Factor20); the significance level was set at p ≤ 0.05 for all the analyses. Results: Internal consistency was verified using Cronbach’s alpha and was adequate (domains α ≥ 0.69; total α = 0.87), in addition to test-retest reliability (domains ICC ≥ 0.82; total ICC = 0.95). Divergences were found between the PID-5-BF different domains despite them being significantly correlated with each other. Convergent validity with the NEO-PI-R was adequate, with moderate/strong correlations between the domains theoretically associated (r > 0.38). The internal structure (Exploratory Factor Analysis) indicated that the original five-factor model (CFI = 0.991; TLI = 0.986; RMSEA = 0.033) and one-factor model were adequate (CFI = 0.908; TLI = 0.899; RMSEA = 0.089. Conclusions: The findings support using the PID-5-BF Brazilian version, which presented adequate psychometric properties comparable to the original version. This instrument can be helpful in the clinical and research fields to screen general and specific traits of personality pathology. Future studies are suggested to expand the psychometric findings among clinical samples, confirming the instrument’s scope of reach.

The sensitivity of the ICD-11 trait model to the symptoms of clinical disorders in young adults.

Hierarchical psychopathology contributes to providing a broader picture of the links between emerging personality structures such as the DSM-5/ICD-11 trait models and clinical disorders. The present study aimed to predict the specific and general clinical symptoms by the less studied constructs of the ICD-11 model (negative affectivity, detachment, dissociality, disinhibition, and anankastia). Data from 642 young adults from Iran (63% female, 18-34 years) were collected by three mental symptom scales and the Personality Inventory for DSM-5 (PID-5), which was recently used to harmonize the constructs of the DSM-5 and ICD-11 trait models. Multiple linear regressions showed that the ICD-11 model significantly predicted both the specific clinical symptoms (ranging from R2 = 0.15 to 0.40) and the general factor of clinical symptoms extracted by exploratory factor analysis (R2 = 0.40, all p < 0.001). Negative affectivity was the strongest construct correlated with both the specific symptoms (ranging from β = 0.36 to 0.69) and the general symptom factor (β = 0.59, all p < 0.001). Because the ICD-11 trait model is a practical structure related to the clinical psychopathology in young adults, screening for maladaptive traits can help clinicians in case formulation for diagnosis and treatment.

No Initial Elevation on Personality Self-Reports in an Online Convenience Sample

Research shows that people’s self-reports may be biased by an initial elevation phenomenon in which ratings are higher the first time that people take a survey as compared to the second and subsequent times. Apart from the fact that this phenomenon exists, and that it might bias ratings for negative subjective experiences more strongly than positive ones, little else is known. In the present study, we examined whether the initial elevation phenomenon occurs for commonly used trait measures, such as ratings on personality inventories and life satisfaction. We hypothesized that the initial elevation phenomenon may be associated with the (un)desirability of the content of the self-report items such that scores for undesirable facets would show initial elevation and scores for desirable facets would show the reverse. We tested this in an online convenience sample (N = 3,329) using 5 facets of a personality inventory and a single item measure of life satisfaction. Our hypotheses were not supported. Our findings suggest that at least for online convenience samples, ratings on personality inventories and life satisfaction are not strongly impacted by initial elevation.

Assessing malingering and personality styles in dissociative identity disorder: a case study

ABSTRACT Dissociative Identity Disorder (DID), formerly Multiple Personality Disorder, involves two or more distinct identities controlling behaviour, stemming from trauma-related dissociation. Understanding DID’s cognitive, neural, and psychometric aspects remains a challenge, especially in distinguishing genuine cases from malingering. We present a case of a DID patient with nine identities, evaluated to rule out malingering. Using the Millon Index of Personality Styles, we assessed the primary and two alternate identities, revealing marked differences. High consistency scores support validity. We suggest employing personality inventories beyond symptomatology to characterise dissociative identities’ consistency and adaptation styles, aiding in malingering assessments in future studies.

The relationship between nomophobia and latent classes of personality.

The phenomenon of nomophobia, defined as the anxiety experienced when a person is without their mobile phone or is unable to use it, has been identified as having serious negative effects on individuals, particularly students. Previous research has explored the relationship between personality traits and nomophobia, but the findings have been inconclusive. The main objective of this study was to classify personality types through latent class analysis and explore the relationship between these personality types and nomophobia. The Chinese version of the Nomophobia Scale and the Chinese brief version of the Big Five Personality Inventory were used in this study to survey 1906 Chinese college students. The results indicated that (1) a four-class model provided the best fit and categorized the personality traits as the overcontrolled class, resilient class, moderate class, and vulnerable class; (2) significant differences were observed between the four personality types and nomophobia, with overcontrolled and resilient personality types consistently scoring significantly lower than moderate and vulnerable personality types. Our finding highlights the key feature of the study.

The Attachment-Caregiving Questionnaire as a Personality Inventory Sensitive to Psychological Vulnerabilities: A Pilot Study

Evolution enabled the human species to form attachment relationships, where a caregiver looks after a needy attacher. In early-life interactions with a parent-caregiver, the child-attacher acquires adaptive durable information—the attachment dimensions—which become part of their personality. As such, the dimensions affect vulnerability to psychological conditions, but the precise nature of this link remains controversial. With this pilot study, we addressed this issue. Considering a sample of 67 psychotherapy patients, we tested (H1) the expected connections between dimensions and specific vulnerability to psychological conditions and (H2) the capability of a self-report to detect such links. We relied on the Attachment-Caregiving Questionnaire (ACQ) to measure seven dimensions and test the hypotheses by (1) investigating the correlation between the patients’ dimensions and their symptoms and (2) building logistic regression models to test whether the dimensions can predict vulnerability to specific symptoms. Our analysis demonstrated that almost all expected dimensions could predict vulnerability to related symptoms. Given the limited sample size, one dimension could not be connected to any symptoms. This study provides preliminary support for the connections between attachment dimensions and vulnerability to clinical conditions and the ACQ’s capability in detecting such links. Further testing is required.

Relationship between Personality Characteristics and Spiritual Health

Abstract Background: Spirituality significantly impacts our well-being. Objectives: This study aims to investigate the role of personality traits and Spiritual Well-Being (SWB) responses. Methods: We utilized the Five Factor Personality Inventory and the Spiritual Health and Life Orientation Measure. A total of 264 individuals aged 18 to 80 (M=37.17; SD=13.88) participated, with 78% female and 22% male. Results: Our findings indicate that individuals with higher levels of extraversion (β=-0.15) have greater spiritual well-being. Individuals who have higher levels of openness to experience (β=0.19) and neuroticism (β=0.17) tend to have lower spiritual health. Conclusion: Extraverted individuals perceive enhanced development in spiritual ideals, resulting in elevated levels of spiritual health. Future research could explore additional factors influencing spiritual well-being. Keywords: Personality Factors, Spiritual Well-Being, Extraversion, Correlational Study.

An Analysis and Observation of Anxiousness and Risk-taking Traits among Firefighters: Implications for Training and Support Programs

This research explores the personality traits of anxiousness and risk-taking among firefighters using the Personality Inventory for DSM-5 (PID-5) and also understands these traits in context with the experiences of the fire fighters shared by them in the workshop. A workshop on Role of Mob Psychology in emergency situation was conducted with 30 firefighters from Ahmedabad, Gujarat. The PID-5 was administered, focusing on the domains of Anxiousness and Risk-Taking. The study aims to understand the relation between risk taking behavior and anxiousness trait of the fire fighters. It also explores the implications experience sharing on job performance, team dynamics, and safety outcomes on the basis of interaction with them and providing insights for tailored training and support programs. It is concluded that the sharing of the experiences of senior officers and field staff may help them in confronting the emergency situation.

Influence of the typology and timing of childhood trauma in psychoticism.

Child maltreatment (CM) is associated with psychosis; however little is known about the frequency, type, and timing of abuse in the personality pathology domain of psychoticism (PSY) in the DSM-5. The purpose of this study was to analyze childhood trauma typology and frequency according to gender and to identify sensitive periods of susceptibility to CM in women with high PSY. The Maltreatment and Abuse Chronology Exposure (MACE) scale was used to evaluate the frequency, severity and timing of each type of maltreatment. The full sample consisted of 83 participants with different psychiatric diagnoses. Psychoticism was assessed with the DSM-5 Personality Inventory (PID-5). To identify the differences in CM exposure between the PSY+ (high psychoticism) and PSY- (low psychoticism) groups, the Mann-Whitney U test, the chi square test and random forest (RF) test were used. Comparing PSY + and PSY-, revealed gender differences in the impact of abuse, with highly frequent and severe types of abuse, in women. In women, PSY + and PSY-, were differentiated especially in non-verbal emotional abuse, peer physical bullying and parental verbal abuse. Several periods with a major peak at age seven followed by peaks at age 17 and 12 years old were identified. Increased exposure to CM occurs in women with PSY+. A sensitivity to CM exposure during early childhood and late adolescence could be a risk factor for psychoticism in women.

A cross-sectional study of the association of exposure to web-based streaming platforms on the psychosocial behaviour and the sleep pattern of Indian youth

Background The rapid proliferation of web-based streaming platforms has become a ubiquitous aspect of contemporary life, especially among the youth in urban areas. This study seeks to delve into the usage patterns and discern potential associations between web-based streaming platforms and the psychosocial behaviour, sleep patterns, and work and study routines of Indian youth in the Wardha District of Maharashtra and Central India. With the escalating prevalence of digital entertainment, understanding the impact on this demographic's mental well-being and lifestyle is imperative. Methods Employing a cross-sectional design, this study will involve youth aged 15-29 from urban communities and schools in the designated district. The sample size, determined by the Cochran formula, is 170 participants. A comprehensive data collection process will unfold by utilising validated assessment tools, including the Young's Internet Addiction Test, WHO (Five) Well-Being Index, Pittsburgh Sleep Quality Index, and Eysenck's Personality Inventory. Statistical analyses, encompassing descriptive statistics, association tests, and regression analyses, will be conducted using SPSS version 23 software. Expected Outcome Anticipated outcomes of this study encompass a nuanced understanding of web-based streaming platform usage patterns, unveiling potential associations with psychosocial behaviours, sleep patterns, and work and study routines among Indian youth. The results are poised to contribute valuable insights into the intricate interplay between digital entertainment and the well-being of the urban youth population. Such findings can inform future interventions and strategies to foster a balanced and healthy digital lifestyle.

Clinical and Psychological Characteristics of Patients after First-Episode Psychosis with Cognitive, Emotional, and Volitional Deficiencies: Comparative Analysis

This research featured 139 patients (60 men, 79 women) after the first-episode psychosis. All patients demonstrated cognitive and/or emotional deficiency. The research objective was to compare clinical, sociodemographic, psychosocial, and individual characteristics. The expert clinical assessment revealed three groups. Group I included 29 patients with negative symptoms in the cognitive sphere; group II consisted of 46 people with negative symptoms in the emotional and volitional sphere; group III included 64 people with no pronounced deficiencies. The authors employed the method of clinical psychological interview and various pathopsychological non-standard methods to study the cognitive activity of the patients. The list of psychometric methods included the Beck’s Depression Inventory, a coping behavior questionnaire, a short version of Minnesota Multiphasic Personality Inventory (MMPI), and the Suicide Risk Assessment Scale. The data obtained were processed using SPSS v. 25.0 and Excel 2010. The three groups demonstrated the following statistically significant differences: diagnosis, critical attitude to one’s own condition, and continuity of psychiatric care (clinical characteristics); social adaptation problems (psychosocial characteristics); association and motivation (cognitive activity); suicidal risk (emotions, personality, and behavior). The MMPI and the coping behavior test also showed differences from the test norm, as well as between the groups. A comparative analysis of clinical and psychological characteristics in patients after the first-episode psychosis makes it possible to develop a correct psychorehabilitation program, prevent deficit symptoms, and improve social functioning.

Examining the relationship between social withdrawal motivations and symptoms of hikikomori

Objective: This study aimed to examine the association between social withdrawal motivations (peer isolation, shyness, unsociability, low mood, and avoidance) and symptoms of hikikomori using both variable- and person-oriented analyses. Method: Adolescents (N = 212) participated in this cross-sectional study. Data were collected using the Social Withdrawal Motivations Scale and the Avoidance subscale of the Child Social Preference Scale-Revised, the 25-item Hikikomori Questionnaire, the Personality Inventory for the DSM-5 Brief Form, and the Interpersonal sensitivity subscale of the Brief Symptom Inventory. Results: Path analysis revealed that peer isolation, shyness, unsociability, and avoidance were associated with symptoms of hikikomori while covarying for age, sex, maladaptive personality, and interpersonal sensitivity. Cluster analysis based on social withdrawal motivations identified four subtypes of adolescents. The group with high social withdrawal motivations showed the highest level of overall personality dysfunction and interpersonal sensitivity. Additionally, the group with high social withdrawal motivations and the group with high avoidance demonstrated higher symptoms of hikikomori compared to the other two groups, after accounting for the effects of the covariates. Conclusions: The findings highlight that the evaluation of co-occurrent social withdrawal motivations may improve the ability to identify those adolescents most in need of support.

Why do companies integrate products and services? Linking decision-makers’ personality traits and decision-making logics

PurposeDespite the increasing attention given to product-service integration (PSI), little is known about this innovation strategy from a key decision-maker’s perspective. To address this gap, our study draws from personality psychology and decision-making (DM) logics theory to better understand why and how companies’ decision-makers strategize for PSI.Design/methodology/approachUsing an abductive, empirics-first approach, we identify the study’s theoretical building blocks, followed by an exploratory quantitative analysis to generate new theory. We propose a fit-as-mediation conceptual framework suggesting that (1) specific personality traits [i.e. honesty-humility (H), emotionality (E), extraversion (X), agreeableness (A), conscientiousness (C) and openness to experience (O) (HEXACO)] make decision-makers more likely to include PSI in their company’s strategy and (2) depending on their personality, they apply different DM logics (i.e. causation or effectuation) to do so. To empirically examine this, we use data from 289 SMEs’ decision-makers.FindingsWe report several meaningful relationships among our key theoretical constructs. For instance, we find that conscientious decision-makers are more likely to develop a PSI strategy via causation, whereas extravert decision-makers are more likely to do so via both causation and effectuation.Originality/valueThis service study is the first to apply the well-established HEXACO Personality Inventory to companies’ key decision-makers. Moreover, it contributes to the microfoundations of PSI strategy and DM logic theories.

Personality Traits and Internet Addiction among Adolescent Students: The Moderating Role of Family Functioning

Objectives: Internet addiction is a behavioral addiction characterized by excessive and compulsive use of the internet. The risk of internet addiction among adolescents has risen recently due to an increase in technological advancement and globalization. However, previous studies have focused on the precipitating factors triggering the internet addiction without looking at the exogenous factors and boundary conditions, such as family functioning, that can either sustain or weaken such behavior. Thus, the present study aimed to examine the moderating role of family functioning in the relationship between personality traits and internet addiction among adolescents. Methods: This study is a cross-sectional study consisting of 3150 adolescent students in the grade/class level of JSS1-SS3 who were assessed with standardized measures of the Big-Five Personality Inventory, Internet Addictive Test, and Family APGAR Index. Pearson correlation was used to explore the bivariate relationships between the demographic variable and other variables of interest, while Hayes regression-based PROCESS macro for SPSS was used to test the Hypotheses. Results: (1) Openness to experience, conscientiousness, extraversion, and neuroticism positively correlated with internet addiction, whereas agreeableness was negatively associated with internet addiction. (2) Positive family functioning correlated negatively with internet addiction. (3) Positive family functioning moderated the relationships of extraversion and agreeableness with internet addiction but not on openness to experience, conscientiousness, and neuroticism with internet addiction. Conclusions: Positive family functioning correlated negatively with internet addiction among adolescents, suggesting that improving family functioning would be a valuable tactic for reducing adolescents’ susceptibility to personality-related internet addiction.

“I Don’t Mind Them Drinking, as Long as…”: A Cross-sectional Study to Identify Codependence among Primary Caregivers of Patients with Alcohol Dependence in Urban India

Abstract Background: Codependence is a form of relationship addiction, described as a “disease of lost selfhood.” Codependence among primary caregivers adversely impacts treatment outcomes in Alcohol Dependence Syndrome (ADS) patients. Personality traits of the caregiver may also influence codependency and its severity. However, in routine clinical practice, codependence among primary caregivers of alcoholic patients is not assessed and addressed. This study aimed to identify codependence among caregivers of ADS patients and determine its association with personality traits in various subgroups. Materials and Methods: A cross-sectional study was conducted in a private mental health establishment in urban Karnataka, India, among 125 adult primary caregivers of ADS patients who were spending at least 4 h daily with the patient for more than a year. Spann-Fischer codependence scale and Big Five personality inventory were used to assess codependence and personality domains, respectively. Codependence scores were correlated with Big Five personality scores and examined in various subgroups. Results: Among 125 study participants, 103 (82.4%) were female and 81 (64.8%) were spouse of ADS patients. Moderate and high codependency was found in 86 (68.8%) and 38 (30.4%) participants, respectively. Codependence was found to be significantly higher among females (64.5 ± 7.7) than males (57.6 ± 10.9), (t = −2.8, df = 25.6, P = 0.000), independent of the type of relationship with the patient. There was a significant positive correlation with neuroticism personality trait. Sociocultural and economic conditions of the caregiver also contributed to codependence. Conclusions: The study identified the presence of moderate-to-severe codependence, especially among female caregivers of ADS patients. This emphasizes the need for a protocol to assess codependency and personality traits among caregivers of ADS patients to improve treatment outcomes in urban Indian settings.

Surgical treatment may improve depressive and hysterical traits in temporal lobe epilepsy with hippocampal sclerosis: Study using the Minnesota Multiphasic Personality Inventory

AbstractAimThe influence of surgeries on psychiatric symptoms and personality traits is not well known in patients with intractable temporal lobe epilepsy (TLE). We investigated changes in personality traits with respect to postoperative seizure outcomes, etiology, side of surgery, and sex differences.MethodsClinical information was retrospectively collected for 44 patients whose Minnesota Multiphasic Personality Inventory (MMPI) was examined before and 1 year after surgical treatment for drug‐resistant TLE. Postoperative changes in MMPI T‐scores were analyzed using a paired t‐test. Participants were divided into two groups based on postoperative seizure outcome, the presence or absence of hippocampal sclerosis (HS) as the etiology, side of surgery, and sex differences. The effect of these clinical factors on postoperative changes in MMPI T‐scores was evaluated using analysis of covariance (P‐values &lt; 0.05).ResultsThe hypochondria (Hs) scale decreased significantly in all patients (p = 0.022). The postoperative seizure‐free group had a significant decrease in the depression (D) scale (p = 0.037). The HS group had significant decreases in the D scale and the hysteria (Hy) scale (p = 0.016 and 0.004, respectively), and a significant increase in the masculinity‐femininity (Mf) scale (p = 0.009). No significant differences existed between the sides of surgery or sex.ConclusionDepressive traits were improved in patients with postoperative seizure freedom. Depressive and hysterical traits were improved in patients with HS, which may be attributed to a reduction in anxiety and fear associated with aura. Most personality traits are not significantly changed or exacerbated by surgical treatment of TLE.

Dispositional factors in the explanation of symptoms of depression, anxiety, health anxiety and COVID-19 Phobia.

Maladaptive personality, the motivational systems, and intolerance of uncertainty play important roles in the statistical explanation of depression and anxiety. Here, we notably examined for the first time whether symptoms of depression, anxiety, health anxiety, and fear of COVID-19 share similar associations (e.g., variance explained) with these important dispositional dimensions. For this cross-sectional study, data from 1001 participants recruited in Germany (50% women; mean age = 47.26) were collected. In separate models, we examined the cross-sectional associations of the symptoms of depression, anxiety, health anxiety, and fear of COVID-19 with the Personality Inventory for DSM Short Form Plus scales, the Behavioral Inhibition System / Flight-Fight-Freeze System / Behavioral Activation System scales, and Intolerance of Uncertainty scales. Relative weight analyses were used to determine the within-model importance of the different scales in the prediction of the symptoms. All in all, our study showed that maladaptive personality and intolerance of uncertainty dimensions are more important sets of predictors of the studied outcomes (with which depressive and anxious symptomatology feature very similar associations) than are the motivational system dimensions. Within predictor sets, the scales with the most important predictors were: Negative Affectivity, the Behavioral Inhibition System, and Burden due to Intolerance of Uncertainty. Our findings highlight the relevance of focusing behavioral targets of psychotherapy on these within-set traits and identify potential research priorities (maladaptive personality and intolerance of uncertainty) in relation to the symptoms of interest.

Personality traits as predictors of recovery among patients with substance use disorder

IntroductionSubstance use disorder (SUD) is often considered a chronic illness in which prolonged recovery, in terms of abstinence, is uncommon. Personality has been found to predict recovery, but not much is known about its long-term predictive ability as the majority of previous studies have had short follow-up periods (≥ one year). The current longitudinal cohort study therefore investigated whether personality traits predict short- (STR) as well as long-term recovery (LTR) in SUD patients. MethodsTreatment-seeking patients with SUD (n = 123) completed the NEO Personality Inventory – Revised. STR and LTR categories were defined as scoring <8 on the Alcohol Use Disorders Identification Test – C and <2 on the Drug Use Disorder Identification Test – C at the one-year and 6–8-year follow-up, respectively. Whether personality traits predicted outcome was investigated by two-tailed independent samples t-tests, α < 0.05. Additional analysis was conducted with latent growth curve model. ResultsNeuroticism (inversely, p = .004, d = 0.55) and Extraversion (p = .04, d = 0.38) predicted STR (n = 114). Although not significant the effect size for Conscientiousness was above the cut-off for a practical significant effect (d = 0.31). No traits predicted LTR category. Still, the effect sizes for LTR regarding Neuroticism (d = 0.36), Extraversion (d = 0.21) and Conscientiousness (d = 0.27) indicated that these traits have relevance for LTR. The latent growth curve model indicated that these traits predicted the short-term use of drugs and long-term use of alcohol in this cohort dominated by patients suffering from severe poly-SUD. ConclusionPersonality traits predict recovery. The effect sizes indicate that more studies with larger samples on personality traits and LTR are required to understand their possible influences on the recovery process.

Identifying tripartite relationship among cortical thickness, neuroticism, and mood and anxiety disorders

The number of young adults seeking help for emotional distress, subsyndromal-syndromal mood/anxiety symptoms, including those associated with neuroticism, is rising and can be an early manifestation of mood/anxiety disorders. Identification of gray matter (GM) thickness alterations and their relationship with neuroticism and mood/anxiety symptoms can aid in earlier diagnosis and prevention of risk for future mood and anxiety disorders. In a transdiagnostic sample of young adults (n = 252;177 females; age 21.7 ± 2), Hypothesis (H) 1:regularized regression followed by multiple regression examined relationships among GM cortical thickness and clinician-rated depression, anxiety, and mania/hypomania; H2:the neuroticism factor and its subfactors as measured by NEO Personality Inventory (NEO-PI-R) were tested as mediators. Analyses revealed positive relationships between left parsopercularis thickness and depression (B = 4.87, p = 0.002), anxiety (B = 4.68, p = 0.002), mania/hypomania (B = 6.08, p ≤ 0.001); negative relationships between left inferior temporal gyrus (ITG) thickness and depression (B = − 5.64, p ≤ 0.001), anxiety (B = − 6.77, p ≤ 0.001), mania/hypomania (B = − 6.47, p ≤ 0.001); and positive relationships between left isthmus cingulate thickness (B = 2.84, p = 0.011), and anxiety. NEO anger/hostility mediated the relationship between left ITG thickness and mania/hypomania; NEO vulnerability mediated the relationship between left ITG thickness and depression. Examining the interrelationships among cortical thickness, neuroticism and mood and anxiety symptoms enriches the potential for identifying markers conferring risk for mood and anxiety disorders and can provide targets for personalized intervention strategies for these disorders.
