The Labor Market with People in It: Personality Traits and Employment Dynamics.

Issues pertaining to the organization and efficiency of the labor market and to the dynamics of employment and unemployment have always been at the forefront of the concerns of economists. Typically, such issues are approached through the analysis of the conflicting interests of a representative worker and of a representative firm, each of which intending to maximize the corresponding intertemporal objective function. Much of the research undertaken on this subject neglects the fact that each person is unique and endowed with different personality traits that influence their educational attainment, their ability to access jobs, their productivity while employed, and also their willingness to support, through social welfare mechanisms, those who become unemployed. In this research, we propose a simulation model to approach the dynamics of the labor market. The model conceives an economy populated by a large number of individuals who, over their life cycles, acquire education, search for a job, receive a wage while employed, and access an unemployment benefit while out of work. Because individuals are endowed with different personalities, they experience different degrees of professional success over their life cycles. Such reasoning leads to a labor market aggregate outcome characterized by emergent phenomena, out-of-equilibrium, path dependence, and other features that are characteristic of a complex evolving system. In the proposed setting, the personality of individuals is shaped by taking into account the big five personality traits of psychological analysis, namely openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism.

O florir da violeta: um estudo de caso em avaliação terapêutica / The flowering of violet: a case study in therapeutic assessment / La flor de la violeta: un estudio de caso en evaluación terapéutica

A Avaliação Terapêutica (AT) é um processo avaliativo e interventivo proposto para ser semiestruturado e colaborativo com o objetivo de promover mudanças positivas no cliente, que é convidado a ter uma participação ativa durante o processo. Na AT, os resultados dos testes psicológicos padronizados ganham destaque como facilitadores do processo de autoconhecimento do cliente. Desse modo, usualmente, integram-se os achados de testes psicológicos de autorrelato com os métodos projetivos para gerar informações que possam ampliar a visão que o cliente tem de si. Neste artigo, buscou-se compreender o potencial de uso dos testes psicológicos e da relação colaborativa a partir de um caso atendido na perspectiva da AT. A participante, Violeta (nome fictício), foi atendida em 10 sessões com duração entre 60 e 115 minutos. Foram utilizados os testes psicológicos Escala de Bem-Estar Psicológico (Ebep), Escala de Vulnerabilidade e Estresse no Trabalho (Event), Bateria Fatorial de Personalidade (BFP), Método de Rorschach e Inventários de Habilidades Sociais 2 (IHS-2). Observou-se que, durante o processo, Violeta ampliou sua autopercepção, o que possibilitou mudanças no modo de agir em seus relacionamentos amorosos e na reflexão sobre como sua postura era vista por si e por seus colegas de trabalho. Acredita-se que a AT cumpriu com o objetivo de estabelecer uma experiência terapêutica que possibilitasse mudanças positivas para a cliente. Este estudo de caso contribuiu para ampliar a compreensão sobre a importância e o uso dos testes psicológicos neste modelo de avaliação psicológica.(AU)

The Therapeutic Assessment (TA) is an evaluative and interventional process proposed to be semi-structured and collaborative with the objective of promoting positive changes in the client, who is invited to have an active participation during the process. At the TA, the results of standardized psychological tests are highlighted as facilitators of the client's self-knowledge process. In this way, the findings of psychological self-report tests are usually integrated with projective methods to generate information that can broaden the client's view of themselves. In this article, understanding the potential use of psychological tests and of the collaborative relationship from a case treated from the TA perspective was sought. The participant, Violet (fictitious name), was assisted in 10 sessions lasting between 60 and 115 minutes. The psychological tests Psychological Well-Being Scale (EBEP), Vulnerability and Stress at Work Scale (EVENT), Personality Factorial Battery (BFP), Rorschach Method and Social Skills Inventories 2 (IHS-2) were used. It was observed that, during the process, Violet increased her self-perception, which allowed changes in her way of acting in her love life and in her reflection on how her posture was seen by herself and herco-workers. It is believed that TA fulfilled the objective of establishing a therapeutic experience that would enable positive changes for the client. This case study contributed to broaden the understanding about the importance and use of psychological testing in this psychological assessment model.(AU)

Así, se cree que ET ha cumplido el objetivo de establecer una experiencia terapéutica que permitió cambios positivos a la cliente. Este estudio contribuyó a ampliar la comprensión sobre la importancia y el uso de las pruebas psicológicas en este modelo de evaluación psicológica.(AU)

Regional personality assessment through social media language.

OBJECTIVE: We explore the personality of counties as assessed through linguistic patterns on social media. Such studies were previously limited by the cost and feasibility of large-scale surveys; however, language-based computational models applied to large social media datasets now allow for large-scale personality assessment. METHOD: We applied a language-based assessment of the five factor model of personality to 6,064,267 U.S. Twitter users. We aggregated the Twitter-based personality scores to 2,041 counties and compared to political, economic, social, and health outcomes measured through surveys and by government agencies. RESULTS: There was significant personality variation across counties. Openness to experience was higher on the coasts, conscientiousness was uniformly spread, extraversion was higher in southern states, agreeableness was higher in western states, and emotional stability was highest in the south. Across 13 outcomes, language-based personality estimates replicated patterns that have been observed in individual-level and geographic studies. This includes higher Republican vote share in less agreeable counties and increased life satisfaction in more conscientious counties. CONCLUSIONS: Results suggest that regions vary in their personality and that these differences can be studied through computational linguistic analysis of social media. Furthermore, these methods may be used to explore other psychological constructs across geographies.

Personality and health-related quality of life (HRQoL) of Hong Kong Chinese older people: resilience as a mediator and financial status as a moderator.

Objectives: Personality can influence older adults' health and quality of life. However, the pathways are relatively less examined. This study aimed to understand the mediating effect of resilience in the relationship between two personality traits-neuroticism and extraversion-and Hong Kong Chinese older adults' health-related quality of life (HRQoL). Whether such effect varied across older adults in different financial conditions were also examined. Method: A purposive non-probability sample of 253 Hong Kong Chinese older adults aged 60 and above was recruited for a face-to-face questionnaire survey. Neuroticism and extraversion were measured using the subscales form the Big Five Inventory (BFI). Resilience was measured by the 10-item Connor-Davidson Resilience Scale (CD-RISC). HRQoL was measured by the short-form 8 (SF- 8). Path analysis was conducted to examine the relationship between key variables. Multi-group path analysis was also performed to investigate whether the pathways differed by financial status. Indirect effects were computed in the path analyses to detect the mediatory role of resilience between personalities and HRQoL.Results: The findings included that after controlling for confounders, neuroticism, but not extraversion was significantly associated with HRQoL. The relationships were mediated by resilience. Moreover, the mediating role of resilience is more pronounced among the participants who live in a financially poor or fair condition, comparing to their wealthier peers.Conclusion: This study confirmed the important role of personality in shaping older adults' resilience and quality of life. Personality should be kept in mind in the identification of potential vulnerable groups for interventions, especially those in financial hardships who may face double disadvantages.

Which personality traits can mitigate the impact of the pandemic? Assessment of the relationship between personality traits and traumatic events in the COVID-19 pandemic as mediated by defense mechanisms.

The COVID-19 pandemic has had a significant influence on the lives of people around the world and could be a risk factor for mental health diseases. This study aimed to explore the psychological impact of the COVID-19 pandemic by identifying patterns related to post-traumatic symptoms by considering personality and defensive styles. Specifically, it was hypothesized that neuroticism was negatively associated with impact of event, as opposed to extraversion, agreeableness, conscientiousness, and openness traits. The mediation role of mature, neurotic, and immature defenses in these relationships was also investigated. This study involved 557 Italian individuals (71.3% women, 28.7% men; Mage = 34.65, SD = 12.05), who completed an online survey including the Impact of Event Scale-Revised, Forty Item Defense Style Questionnaire (DSQ-40) and Ten Item Personality Inventory. Results showed a nonsignificant effect for extraversion and openness on impact of event. The negative influence of neuroticism was instead confirmed in a partial parallel mediation involving significant effects from immature and neurotic defenses in the indirect path. Finally, agreeableness and conscientiousness delineated two protective pathways regarding impact of event, determining two total parallel mediation models in which both these personality traits were negatively associated with immature defensive styles, and conscientiousness was also positively related to mature defenses. These findings provide an exploration post-traumatic symptom patterns during the COVID-19 pandemic, involving the big five personality traits and defense mechanisms. These results may be useful for developing interventions, treatments, and prevention activities.

An Indonesian model of well-being: The integration of universal and cultural factors.

The current study examined a predictive model of both universal factors (socioeconomic, neuroticism, and extraversion) and culturally specific factors (sense of community, trust, and self-construal) towards the well-being of Indonesians. A nationally representative sample (N = 929) was recruited across the nation to complete a survey in either online or offline format. The survey contained a measure of well-being as well as demographic, psychosocial, and cultural variables. Analysis via hierarchical multiple regression showed that both universal and cultural factors were associated with well-being in this Indonesian sample. In particular, once the cultural factors were added to the model, there were changes in universal factor effects to well-being. The finding of this study recognized the multidimensional model of well-being and supports the importance of evaluating well-being at the dimensional level to allow for an exploration of the nuanced relationship between distinct indicators and facets of well-being. The theoretical implications of these results and future directions were also discussed in this study.

Expanding the Scope of Implicit Personality Assessment: An Examination of the Questionnaire-Based Implicit Association Test (qIAT).

Self-report questionnaires can only yield information that people are able and willing to report, but implicit assessment methods are not commonly used in mainstream personality research. The Questionnaire-based Implicit Association Test (qIAT) was designed to address the limitations associated with the conventional self-concept IAT, and it enables an indirect assessment that is based on the items of standard self-reports. The present studies examined the psychometric properties of the qIAT across two personality constructs. Study 1 (N = 528) provided support for the internal consistency, test-retest reliability and convergent and discriminant validity of the qIAT that measured extraversion. Study 2 (N = 164) supported the reliability and validity of the qIAT assessment of conscientiousness, which predicted who returned to complete the second session of the study two weeks later, for which participants were paid in advance. This same prediction effect was marginally significant in Study 3 (N = 200), and across both Studies 2 and 3 the qIAT prediction of the criterion behavior was incremental to the parallel self-report questionnaire. Taken together, findings support the reliability and validity of the qIAT, which enables the indirect measurement of a wide variety of distinct personality constructs, currently measured only by self-report scales.

Indecisão e maturidade vocacional, autoeficácia e personalidade em adolescentes com e sem superdotação / Vocational and maturity indecision, self-efficacy, and personality in gifted and non-gifted adolescents / Indecisión y madurez vocacional, autoeficacia y personalidad en adolescentes superdotados y no superdotados

O objetivo deste estudo foi comparar as características sociodemográficas, nível de indecisão vocacional (EIV), autoeficácia geral percebida (EAGP), personalidade (BFP) e maturidade para a escolha profissional (EMEP) de adolescentes com e sem superdotação. A amostra foi composta por 31 adolescentes com idade média de 16,29 anos (DP = 1,21), 12 com superdotação e 19 sem superdotação. Os superdotados foram recrutados em um Núcleo Estadual de Altas Habilidades/Superdotação e os sem superdotação em uma escola particular. Os dois grupos de adolescentes responderam os mesmos instrumentos: ficha de dados sociodemográficos, EMEP, EIV, BFP e EAGP. Os sem superdotação apresentaram menores níveis de autoeficácia (EAGP) e maiores níveis de neuroticismo (BFP) e responsabilidade (EMEP). Já os adolescentes com superdotação obtiveram maiores níveis de realização (BFP), autoeficácia (EAGP), determinação (EMEP), extroversão e abertura (BFP) e autoconhecimento (EMEP). Os resultados contribuem para que orientadores profissionais e de carreira desenhem intervenções mais assertivas para adolescentes superdotados. (AU)

The aim of the study was to compare the sociodemographic characteristics, level of vocational indecision (EIV), perceived general self-efficacy (EAGP), personality (BFP) and maturity for professional choice (EMEP), of adolescents with and without giftedness. The sample consisted of 31 adolescents with a mean age of 16.29 years (SD = 1.21), 12 with giftedness and 19 without. The gifted students were recruited from a State Center for High Skills/Giftedness and the non-gifted students from a private school. The two groups of adolescents answered the same instruments, including a sociodemographic data form, the EMEP, EIV, BFP and EAGP. The non-gifted students presented lower levels of self-efficacy (EAGP) and higher levels of neuroticism (BFP) and responsibility (EMEP). The gifted adolescents presented higher levels of achievement (BFP), self-efficacy (EAGP), determination (EMEP), extraversion and openness (BFP), and self-knowledge (EMEP). The results can help professional and career counselors to design more assertive actions for gifted adolescents. (AU)

Socio-economic inequality and risk of loneliness by personality traits in girl students.

OBJECTIVE: Personality traits can affect humans' mental health. In the present study, we aimed to assess the relation of loneliness to personality traits and also to inequality in socio-economic status in girl students. METHODS: In a cross-sectional study, investigated the relations of personality traits to loneliness in girl students in Ilam from 2014 to 2015. A multistage cluster random sampling method was used to select the participants. The NEO-FFI and University of California, and Los Angeles questionnaires were used for data collection. Data were analyzed by IBM SPSS and Distributive Analysis Stata Package (DASP). RESULTS: Among 400 recruited participants, 149 (37.2%) were categorized as having loneliness. The concentration index (CI) for loneliness was 0.19 (95 % confidence interval CI] 0.07, 0.27), which indicated that loneliness was observed more in persons with high socioeconomic status. The risk of loneliness was 38% lower in persons with higher scores in neuroticism (adjusted odds ratio (AOR) = 0.62, 95% CI: 0.48, 0.91). CONCLUSION: We found that socio-economic inequality was observed in relation to loneliness with girls of higher socioeconomic status reporting more loneliness. Therefore, more attention should be directed by policymakers to determining the main contributors to inequality contributors and loneliness in advantaged societies.

Association of Socioeconomic, Personality, and Mental Health Factors With Health-Related Quality of Life in Patients With Facial Palsy.

Importance: Knowledge of factors associated with health-related quality of life in patients with facial palsy may aid in better interpreting outcomes of research and treatment. Objective: To identify factors associated with health-related quality of life in patients with facial palsy. Design, Setting, and Participants: The inclusion period for participants in this cross-sectional study at the University Medical Center Groningen, a tertiary referral center for facial reanimation surgery, was March 1 to June 1, 2019. Patients aged at least 18 years with facial palsy who had undergone surgery for facial palsy between January 1, 2007, and January 1, 2018, and patients visiting the outpatient clinic of the University of Groningen Department of Plastic Surgery for their facial palsy between March 1 and June 1, 2019, were also asked to participate. Of 276 patients invited, 145 gave informed consent. Twenty patients did not respond after consent, 3 patients withdrew from the study, and 1 patient was wrongly included. Main Outcomes and Measures: Health-related quality of life was measured using the Facial Clinimetric Evaluation Scale and the Facial Disability Index (physical score and social score). Facial function was assessed with the Sunnybrook Facial Grading System. Other variables were investigated using validated questionnaires, including the Duke University Religion Index, Ten-Item Personality Inventory, and Hospital Anxiety and Depression Scale. Multivariable linear regression analyses with stepwise backward selection were performed to identify associations with health-related quality of life. Because 44 Sunnybrook composite scores were missing, a sensitivity analysis was performed that excluded the Sunnybrook composite scores from the multivariable analysis. Results: In total, 121 patients with facial palsy were included; their median age was 62 years (interquartile range, 48-71 years), and 63 (52%) were women. Sunnybrook composite score (ß = 0.4; 95% CI, 0.2-0.5), extraversion (ß = 2.6; 95% CI, 0.4-4.8), and anxiety (ß = -2.4; 95% CI, -4.1 to -0.8) were associated with the Facial Clinimetric Evaluation Scale total score (R2 = 0.380; 95% CI, 0.212-0.548). The Sunnybrook composite score was associated with the Facial Disability Index physical score (ß = 0.2; 95% CI, 0.0-0.4) (R2 = 0.084; 95% CI, -0.037 to 0.205). Bilateral facial palsy (ß = -21.2; 95% CI, -32.3 to -10.1), extraversion (ß = 2.7; 95% CI, 1.3-4.1), conscientiousness (ß = 2.7; 95% CI, 0.2-5.2), emotional stability (ß = 3.3; 95% CI, 1.7-4.8), and depression (ß = -1.3; 95% CI, -2.5 to -0.1) were associated with the Facial Disability Index social score (R2 = 0.400; 95% CI, 0.262-0.538). In the sensitivity analysis, the Sunnybrook composite score was associated with age (Spearman ρ = -0.252). Conclusions and Relevance: Bilateral facial palsy, age, severity of facial palsy, mental distress, and personality traits should be taken into account in future research and treatment of patients with facial palsy.

Quality of life and social participation in dental rehabilitation: A personality and multi-informant perspective.

OBJECTIVES: Contemporary research on the impact of dental rehabilitation scarcely focuses on the role of personality and social relationships in QoL related to dental implant treatment. To overcome biases related to evaluation with self-reports, descriptions provided by informed external observers are recommended. AIMS: To investigate the impact of implant-supported rehabilitation on quality of life and social participation taking into account patient's personality. MATERIALS AND METHODS: Fifty-four patients were included in this study and assigned to either a single unit group (n = 15) or a complete jaw restoration group (n = 39). Of the 54 participants, 49 nominated an external observer who can evaluate the daily behavior of the patient. Before and after treatment patients and their external observer completed the OHIP-14, the NEO-FFI and the MSPP questionnaires respectively focusing on Oral Health related Quality of Life, Personality and Social participation. RESULTS AND CONCLUSION: The correlations between self- and observer ratings on pre and post treatment outcomes on were insignificant (QoL pre: p = 0.086, post: p = 0.115, freq. soc. part pre: p = 0.944, post: p = 0.876, div. soc. part pre: p = 0.798, post: p = 0.167), suggesting considerable differences in observer perspectives. The traits Neuroticism, Extraversion and Agreeableness were associated with QoL. Openness, Conscientiousness and Agreeableness were associated with social participation. Patients in the complete jaw restoration group reported more impact of the implant treatment on quality of life as compared to the single unit group (p = 0.007). The complete jaw restoration group reported an improved quality of life after treatment and significant increases of both frequency (p = 0.001) and diversity of social participation (p = 0.036). In conclusion there was a minor impact of treatment with single crowns on quality of life and social participation compared to the full denture group. The role of personality and the use of multi-informants in evaluating dental treatment was found important.

Social Integration, Self-Rated Health . . . and Genes?

Objective: This study examined genetic roots of later life social integration, and their confounding of this social factor's health linkages. Method: Data were from the 2010 wave of the Health and Retirement Study. Two dimensions of integration were examined: with one's "stakeholder" network of family and friends and with the community. Genetic measures included polygenic scores for extraversion and educational attainment. Results: Ties to one's stakeholder network had no genetic associations. The extraversion polygenic score was linked to community integration among Blacks as well as Whites. Among the latter, the same was true of one's genetic propensity for educational attainment. Although this score also influenced self-rated health, neither confounded associations of social integration with this indicator. Discussion: Later life social integration seems influenced by genetically rooted propensities for both sociability and human capital accumulation. Health linkages of integration, however, may not reflect mutual dependencies on the same genetic substrates.

Neurostructural correlates of optimism: Gray matter density in the putamen predicts dispositional optimism in late adolescence.

Dispositional optimism reflects one's generalized positive expectancies for future outcomes and plays a crucial role in personal developmental outcomes and health (e.g., counteracting related mental disorders such as depression and anxiety). Increasing evidence has suggested that extraversion is an important personality factor contributing to dispositional optimism. However, less is known about the association between dispositional optimism and brain structure and the role of extraversion in this association. Here, we examined these issues in 231 healthy high school students aged 16 to 20 years (110 males, mean age = 18.48 years, SD = 0.54) by estimating regional gray matter density (rGMD) using a voxel-based morphometry method via structural magnetic resonance imaging. Whole-brain regression analyses revealed a significant positive correlation between dispositional optimism and the rGMD of the bilateral putamen after adjusting for age, sex, family socioeconomic status (SES), general intelligence, and total gray matter volume (TGMV). Moreover, prediction analyses using fourfold balanced cross-validation combined with linear regression confirmed a significant connection between dispositional optimism and putamen density after adjusting for age, sex, and family SES. More importantly, subsequent mediation analysis showed that extraversion may account for the association between putamen density and dispositional optimism after adjusting for age, sex, family SES, general intelligence, TGMV, and the other four Big Five personality traits. Taken together, the current study provides new evidence regarding the neurostructural basis underlying dispositional optimism in adolescents and underscores the importance of extraversion as an essential personality factor for dispositional optimism acquisition.

Employees exposed to work-related threats and violence in human services sectors: Are any employees members particularly exposed to violence and threats and what role do supervisors play?

BACKGROUND: The frequency of being exposed to work-related violence and threats is high in employees working in the human service sector. The question is whether certain employees are particularly exposed to violence and threats than others. OBJECTIVE: This study examined whether particular employees were especially exposed to work-related violence and threats due to personal characteristics, coping styles, attitudes or participating in violence prevention training. We also examined the role played by supervisors. METHODS: Questionnaire data were collected in 2010 and 2011. In all, 3584 employees from special schools, psychiatric wards, eldercare and the Prison and Probation Service participated. We used multivariate logistic regression analyses. RESULTS: We found persons high on the extroversion and introversion scales were associated with statistical significant increased risk for work-related threats. Furthermore, accepting attitudes concerning work-related violence were also statistical significant associated with increased the risk for both work-related threats and violence. Associations between coping styles and work-related threats and violence were very small and statistically non-significant and we found no effect of violence prevention training. The risk for work-related threats for persons high on the extroversion scale was decreased if supervisor violence prevention behaviour was high. Furthermore, if supervisor prevention behaviour was high, prevention training decreased the risk for work-related violence. However, these associations weren't statistically significant. CONCLUSION: The results stress that effective prevention requires involvement of both employees and supervisors.

Can a Good Life Be Unsatisfying? Within-Person Dynamics of Life Satisfaction and Psychological Well-Being in Late Midlife.

Psychological investigations into the structure of well-being have been largely cross-sectional. However, longitudinal models are needed as Western societies work to improve individual well-being. The current multilevel-modeling study examined within-person dynamics of well-being over 8 years. I asked two questions: (a) How do life satisfaction and psychological well-being (measures drawn from two well-being research traditions) relate over time? and (b) do these relationships vary on the basis of individuals' extraversion or neuroticism? Measures of life satisfaction and psychological well-being were collected in 8 consecutive years from 159 American adults in late midlife. A dispositional-life-satisfaction set point and yearly variation in life satisfaction both related to higher yearly psychological well-being. Neuroticism, but not extraversion, predicted a stronger within-person relationship between life satisfaction and psychological well-being. For participants with very low neuroticism, life satisfaction and psychological well-being varied independently. In sum, experiences of life satisfaction and psychological well-being converged for more neurotic individuals and diverged for more emotionally stable participants.

Personality Traits Predict Meeting the WHO Recommendation of 6 Months' Breastfeeding: A Prospective General Population Cohort Study.

BACKGROUND: Although personality as well as anxiety and depression are recognized as predictors for breastfeeding initiation, evidence of an association of these factors with 6 months' exclusive breastfeeding as recommended by the World Health Organization (WHO) is sparse. PURPOSE: The purpose of this study was to investigate the associations of personality and symptoms of anxiety and depression during and after pregnancy with meeting the WHO recommendation of 6 months' exclusive breastfeeding. METHODS: In their first trimester of pregnancy, 5784 pregnant women were enrolled in Dutch primary obstetric care centers and hospitals, of which 2927 completed the breastfeeding assessments 6 months postpartum. We performed logistic regression analyses to test the associations of "big five" personality traits (NEO Five Factor Inventory), anxiety (State-Trait Anxiety Inventory), and depression (Edinburgh Postnatal Depression Scale) symptom levels during pregnancy and postpartum with meeting the WHO recommendation of 6 months' exclusive breastfeeding. RESULTS: Agreeableness (odds ratio [OR] = 1.18, P = .006) and openness (OR = 1.31, P < .001) were positively associated with meeting the WHO recommendation, whereas extraversion (OR = 0.83, P = .005) and neuroticism (OR = 1.18, P = .006) were negatively associated. After adjustment for both antenatal and postpartum symptom levels of anxiety and depression, the associations of the agreeableness, extraversion, and openness personality traits remained strong and statistically significant (P < .05). IMPLICATIONS FOR PRACTICE: Patient-centered care should take personality into account in an effort to tailor interventions to optimize breastfeeding behavior. IMPLICATIONS FOR RESEARCH: In contrast to earlier findings, personality traits may be of greater importance than symptoms of anxiety and depression for meeting the WHO recommendation of 6 months' exclusive breastfeeding.

Costs and benefits of acting extraverted: A randomized controlled trial.

Evidence suggests that extraverted (i.e., bold, agentic) behavior increases positive affect (PA), and could be targeted in wellbeing interventions. However, this evidence is either causally ambiguous or has questionable ecological validity, and the potential costs of sustained extraverted behavior have received minimal attention. To address these limitations, we conducted a randomized controlled trial examining the wellbeing benefits and costs of an extraverted behavior intervention conducted in everyday life. Participants (n = 147) were randomly assigned to an "act-extraverted" intervention or a "sham" (active control) intervention for 1 week in everyday life. Additional data for a contact control condition were obtained from a previous study (n = 76). Wellbeing outcomes included PA and negative affect (NA), feelings of authenticity, and tiredness-assessed both in the moment and retrospectively. There was a positive overall effect of the acting extraverted intervention on PA and authenticity. However, wellbeing outcomes also depended on dispositional extraversion: more introverted participants had weaker PA increases, experienced increased NA and tiredness, and decreased feelings of authenticity. Implications for wellbeing interventions and personality theory are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Self-diagnosed depression in the Norwegian general population - associations with neuroticism, extraversion, optimism, and general self-efficacy.

BACKGROUND: Multi-item rating scales for depression informs about the level of depression, but does not allow individuals to state by self-evaluation whether they feel depressed or not. The insider perspective on depression is rarely assessed. This study investigated the prevalence of self-diagnosed depression in the Norwegian general population, and associations with sociodemographic and psychological factors. METHODS: As part of a national survey, the General Self-Efficacy Scale, the Life Orientation Test-Revised, a short version of the Eysenck Personality Questionnaire and a one-item measure of self-diagnosed depression was administered to 5.500 persons in the general Norwegian population. Of the 4961 eligible participants ≥ 18 years of age, 1.787 (response rate 36%) participated in the survey, and 1.684 of these had valid scores on the relevant scales. The associations between sociodemographic factors and self-diagnosed depression were examined using univariate and multivariate logistic regression analyses. RESULTS: One hundred and thirty-six participants (8.1%) reported depression during the preceding month. When adjusting for sociodemographic and psychological variables, higher age (OR = 0.82), being in work (OR = 0.57), and higher levels of general self-efficacy (OR = 0.67) and optimism (OR = 0.52) were associated with lower risk of self-diagnosed depression, whereas higher levels of neuroticism (OR = 1.97) was associated with higher risk. CONCLUSIONS: The prevalence of self-diagnosed depression in the adult Norwegian population was higher for women than for men. Higher age, being in work and having higher levels of psychological resources appear to reduce the risk of self-diagnosed depression, whereas neuroticism increases the risk.

Extraversion and openness to experience moderate the relationship between orthodontic treatment need and oral health-related quality of life in adolescents: A cross-sectional study.

OBJECTIVE: To investigate the effects of personality traits to moderate the relationships between orthodontic treatment need and oral health-related quality of life (OHRQoL) in adolescents. MATERIALS AND METHODS: A cross-sectional study was performed that included 230 subjects (125 girls and 105 boys) aged 11-14 years. Orthodontic treatment need was measured using the Index of Complexity, Outcome and Need (ICON). The Child Perceptions Questionnaire, the Basic Personality Traits Inventory (BPTI), and the Revised Life Orientation Test were used to assess the OHRQoL, basic personality dimensions, and dispositional optimism respectively. Potential moderation effects were evaluated with Spearman's correlations and multiple regression analyses. RESULTS: There were weak correlations between orthodontic treatment need and quality of life with social and emotional well-being dimensions ( r = 0.238, r = 0.296 and r = 0.209). A moderating effect of extraversion was observed in the relationship between orthodontic treatment need and OHRQoL, emotional well-being, and social well-being (SWB) (Δ R2 = 0.03, Δ R2 = 0.02, and Δ R2 = 0.04, respectively). Openness to experience affected relationships between orthodontic treatment need and OHRQoL, and emotional well-being (EWB) (Δ R2 = 0.03 and Δ R2 = 0.04, respectively). In children with higher extraversion, the increase in ICON scores resulted in less increase in CPQ total, EWB, and SWB scores. In children with higher openness to experience, the increase influenced CPQ total and EWB scores similarly. CONCLUSIONS: The relationship between orthodontic treatment need and quality of life is moderated by personality traits. Early adolescents with higher extraversion and openness to experience are less affected by increased orthodontic treatment need.

The Role of Personality in the Assessment of Subjective and Physiological Emotional Reactivity: A Comparison Between Younger and Older Adults.

This study brings more clarity on the inconsistent findings on emotional reactivity differences between older (OA) and younger (YA) adults, by examining the influence of (mal)adaptive personality traits on emotional reactivity and by applying several assessment methods. We recruited 60 YA (25-50 years) and 60 OA (65+ years) from a nonclinical population. We used Visual Analogue Scales to measure subjective reactivity, and facial electromyography (corrugator and zygomaticus reactivity), heart rate, heart rate variability, and skin conductance level to assess physiological reactivity during happy and sad film clips. Results showed that personality influences on emotional reactivity in OA were largely comparable to YA, although the influence of negative emotionality and neuroticism on subjective reactivity in response to the sad film was significantly stronger in OA. It is thus important to assess both subjective and physiological reactivity when comparing age-related differences in OA and YA given the differential relation with personality features.
