An accurate personality model is crucial to many research fields. Most personality models have been constructed using linear factor analysis (LFA). In this paper, we investigate if an effective deep learning tool for factor extraction, the Variational Autoencoder (VAE), can be applied to explore the factor structure of a set of personality variables. To compare VAE with LFA, we applied VAE to an International Personality Item Pool (IPIP) Big 5 dataset and an IPIP HEXACO (Humility-Honesty, Emotionality, Extroversion, Agreeableness, Conscientiousness, Openness) dataset...

The genetic protective factors for cognitive decline in aging remain unknown. Predicting an individual's rate of cognitive decline-or with better cognitive resilience-using genetics will allow personalized intervention for cognitive enhancement and the optimal selection of target samples in clinical trials. Here, using genome-wide polygenic scores (GPS) of cognitive capacity as the genomic indicators for variations of human intelligence, we analyzed the 18-year records of cognitive and behavioral data of 8511 European-ancestry adults from the Wisconsin Longitudinal Study (WLS), specifically focusing on the cognitive assessments that were repeatedly administered to the participants with their average ages of 64...

To enhance formulation and interventions for emotional distress symptoms, research should aim to identify factors that contribute to distress and disorder. One way to formulate emotional distress symptoms is to view them as state manifestations of underlying personality traits. However, the metacognitive model suggests that emotional distress is maintained by metacognitive strategies directed by underlying metacognitive beliefs. The aim of the present study was therefore to evaluate the role of these factors as predictors of anxiety and depression symptoms in a cross-sectional sample of 4936 participants collected during the COVID-19 pandemic...

Social distancing (SD) was an effective way of reducing virus transmission during the deadly and highly infectious COVID-19 pandemic. Using a prospective longitudinal design, the present study explored how the Big 5 traits relate to variations in SD in a sample of university students (n = 285), and replicated these findings using informant reports. Self-determination theory's concepts of autonomous motivation and intrinsic community values were explored as potential mechanisms linking traits to SD. Individuals who were higher on trait agreeableness and conscientiousness engaged in more SD because they more effectively internalized the importance and value of the guidelines as a function of their concerns about the welfare of their communities...

In many countries, the current vaccination rates are stagnating, to the extent that vaccine hesitancy-the delay or refusal to take recommended vaccinations-forms a major obstacle to ending the COVID-19 pandemic. This tendency is particularly concerning when observed among healthcare workers who are opinion leaders on medical matters for their patients and peers. Our study surveys 965 employees of two large Swiss hospitals and profiles vaccine-hesitant hospital employees using not only socio-demographic characteristics, but also a comprehensive set of standard behavioral preference measures: (i) Big-5 personality traits, (ii) risk-, time- and social preferences, and (iii) perceived prevailing social norms...

BACKGROUND: The sociodemographic and personality profiles of effective peer leaders in the context of diabetes self-management interventions are poorly understood. In this study we explored the demographic and personality characteristics of peer leaders participating in a 12-month, telephone-based type 2 diabetes self-management intervention. METHODS: We used a sequential explanatory mixed-methods research design and recruited 52 peer leaders. Thirty-seven peer leaders had at least 1 participant complete both the baseline and 12-month assessments...

BACKGROUND: Previous evidence has suggested that physically inactive individuals and extensive media users are at high risk for experiencing depressive symptoms. We examined personality traits and perceived social support as potential moderators of this association. Personality and perceived social support were included as two of the most frequently considered variables when determining predispositioning factors for media use phenomena also discussed in relation to physical activity. METHODS: We analysed cross-sectional data from 1402 adults (18-31 years old) who participated in a national health survey in Germany (KiGGS, Study on the health of children and adolescents in Germany, wave 2)...

The aim of the study was to clarify whether personality traits predict the structure, function and quality of egocentric confidant networks in later life. Data were drawn from Waves 7 and 8 of the Survey of Health, Ageing and Retirement in Europe (SHARE) ( N  = 39,172) . We regressed network size, contact frequency and network satisfaction on the Big-5 personality traits, using a single path analysis structure, controlling for country, sociodemographic background and health status. The findings showed that the personality traits were related to the social network outcomes, but their effect was modest and less predictive than the contextual factors...

Victims of Childhood Sexual Abuse (CSA) may be met with skeptical responses when they disclose their experience. The fear of such a response means that most victims delay telling anyone about the abuse. The aim of this study was to explore how contextual factors of abuse such as victim gender and age, perpetrator gender, and victim-perpetrator relationship affect a response to CSA. Further, we explored what personality traits may predict a skeptical response. An online questionnaire with 357 undergraduate students asked participants to read a vignette describing CSA, and to indicate the extent to which they believed the vignette, whether they blamed the victim or perpetrator, and what punishment they would recommend for the perpetrator...

BACKGROUND: Many people suffer from insomnia, a sleep disorder characterized by difficulty falling and staying asleep during the night. As social media have become a ubiquitous platform to share users' thoughts, opinions, activities, and preferences with their friends and acquaintances, the shared content across these platforms can be used to diagnose different health problems, including insomnia. Only a few recent studies have examined the prediction of insomnia from Twitter data, and we found research gaps in predicting insomnia from word usage patterns and correlations between users' insomnia and their Big 5 personality traits as derived from social media interactions...

Objective numeracy, the ability to understand and use mathematical concepts, has been related to superior decisions and life outcomes. Unknown is whether it relates to greater satisfaction in life. We investigated numeracy's relations with income satisfaction and overall life satisfaction in a diverse sample of 5,525 American adults. First, more numerate individuals had higher incomes; for every one point higher on the eight-item numeracy test, individuals reported $4,062 more in annual income, controlling for education and verbal intelligence...

Background: Female intrasexual competition (ISC) represents a unique form of social interaction. It describes behaviors primarily applied to enhance a woman's ability to outcompete other women. Previous research suggests that female ISC is influenced by personality characteristics and sex hormones. Although these factors most likely interact to predict female ISC, no previous study has investigated those factors in parallel in order to link theories from social psychology and biology. Women at the end of the reproductive lifespan represent the ideal study population, as they allow for a controlled hormonal environment...

Acoustic noise is pervasive in human environments. Some individuals are more tolerant to noise than others. We demonstrate the explanatory potential of Big-5 personality traits neuroticism (being emotionally unstable) and extraversion (being enthusiastic, outgoing) on subjective self-report and objective psycho-acoustic metrics of hearing in noise in two samples (total N = 1103). Under statistical control for demographics and in agreement with pre-registered hypotheses, lower neuroticism and higher extraversion independently explained superior self-reported noise resistance, speech-hearing ability and acceptable background noise levels...

A central feature of the Covid-19 pandemic is state differences. Some state Governors closed all but essential businesses, others did not. In some states, most of the population wore face coverings when in public; in other states, <50% wore face coverings. According to journalists, these differences were symptomatic of a politically polarized America. The Big 5 personality factors also cluster at the state level. For example, residents of Utah score high on Conscientiousness and low on Neuroticism , whereas residents of Massachusetts and Connecticut show the opposite pattern...

Interpersonal difficulties are common across psychological disorders and are a legitimate target of treatment. Psychotherapeutic models differ in their understanding of interpersonal problems and how these problems are formulated and treated. It has been suggested that they are both the cause and effect of emotional distress symptoms, that they result from early attachment experiences, and that they are related to personality dimensions. However, the metacognitive model of psychopathology predicts that emotion disorder symptoms and interpersonal problems are linked to a common set of factors involving dysfunctional metacognition...

OBJECTIVES: Personality traits are linked with healthy aging, but it is not clear how these associations come to manifest across the life-course and across generations. To study this question, we tested a series of hypotheses about (a) personality-trait prediction of markers of healthy aging across the life-course, (b) developmental origins, stability and change of links between personality and healthy aging across time, and (c) intergenerational transmission of links between personality and healthy aging...

BACKGROUND AND AIMS: Previous research has demonstrated phenotypic associations between disordered gambling (DG) and Big 5 personality traits, and a twin study suggested shared genetic influences accounted for a substantial portion of this relation. The present study examined associations between DG and polygenic scores (PSs) for Big 5 traits to measure the shared genetic underpinnings of Big 5 personality traits and DG. DESIGN: Zero-inflated negative binomial regression models estimated associations between Big 5 PSs and past-year and lifetime assessments of DG in a longitudinally-assessed population-based birth cohort...

Childhood unpredictability and harshness are associated with patterns of psychology and behavior that enable individuals to make the most of adverse environments. The current research assessed effects of childhood unpredictability and harshness on individual differences in sacrificial moral decision making. Six studies ( N = 1,503) supported the hypothesis that childhood unpredictability, but not harshness, would be associated with fewer decisions to reject harm (consistent with deontological ethics) and to maximize overall outcomes (consistent with utilitarian ethics)...

OBJECTIVES: The personality traits of conscientiousness and neuroticism have been consistently linked to mean-level, self-reported sleep duration and continuity. The present study expands this literature by using actigraphy sleep assessment to examine how personality is related to both mean-level and the intraindividual variability in sleep duration, continuity, and timing. DESIGN: One-week ecological sleep assessment. SETTING: The research was conducted at a mid-size Midwestern university...

People possess psychological processes that help them avoid pathogens, which is particularly important when novel infectious diseases (e.g., COVID-19) spread through the population. Across two studies we examined whether trait pathogen avoidance (operationalized as perceived vulnerability to disease; PVD) was linked with responses to COVID-19 and preventative behaviors. In Study 1, PVD was positively associated with stronger reactions to the threat of COVID-19, including increased anxiety, perceptions that people should alter their typical behavior, as well as reported importance of engaging in proactive and social distancing behaviors...
