RESUMEN

OBJECTIVE: This study aimed to explore the efficiency of different emotion regulation strategies, specifically reappraisal and suppression, in relation to adaptive and maladaptive personality profiles. BACKGROUND: Personality conditions emotions and influences emotion regulation. Of the available regulation strategies, reappraisal (reinterpreting the situation) is described as an efficient strategy, whereas suppression (not displaying the experienced emotion) carries higher physiological and cognitive costs. Little is known, however, about the influence of personality on these efficiencies. METHOD: We tested the personality structure of 102 participants (Meanage = 20.75, SDage = 2.15), based on the Five-Factor Model and the Maladaptive Personality Trait Model. Experience, expressivity, and physiological arousal were recorded during the viewing of emotionally charged positive and negative images while participants reappraised, suppressed, or viewed the images without regulating their emotions. RESULTS: We identified two clusters for adaptive personality ("Adaptive Resilient" and "Anti-resilient") and two for maladaptive personality ("Maladaptive Resilient" and "Under-controlled"). The major finding was for emotional experience in maladaptive personalities, where reappraisal was efficient in the Maladaptive Resilient profile, while none of the strategies brought relief in the Under-controlled profile. CONCLUSION: This study, which systematically contrasts personality and efficiency of emotion regulation strategies, is one of the first attempts to refine the understanding of how personality influences the emotional regulation process.

RESUMEN

BACKGROUND: Findings show that the complex nature of humor and its personality basis can be more comprehensively understood if humor styles are analyzed simultaneously within humor types, rather than separately. PARTICIPANTS AND PROCEDURE: Utilizing two independent samples (N1 = 253, N2 = 353) of self-report responses to the Humor Styles Questionnaire (HSQ) and the Zuckerman-Kuhlman-Aluja Personality Questionnaire-Short Form, this paper outlines how the HSQ responses result in three humor use types following cluster analysis. Cluster differences in humor styles and personality traits were analyzed using ANOVA. RESULTS: In both samples, a humor type characteristic of individuals who scored lower in the positive and higher in the negative humor styles was revealed. People within this humor type also scored significantly higher in the personality measures of neuroticism and aggressiveness. A second humor type replicated in the two studies described individuals scoring higher for each of the four humor styles. People within this type also scored significantly higher on extraversion and sensation seeking, suggesting a need for cortical arousal. The third humor type members scored lower in each of the humor styles (apart from the affiliative humor style scores for one of the samples). This humor type requires further investigation. CONCLUSIONS: In general, humor types provide an additional understanding of humor use as people within the types differ for specific personality dimensions.

RESUMEN

Background: There is little and heterogeneous knowledge on the links between the temperamental predispositions of psychopathology and the contemporary dimensional models of psychopathology, such as the Hierarchical Taxonomy of Psychopathology (HiTOP) classification system, which can be aligned with the five-factor model (FFM) of personality. This meta-analysis seeks to expand the temperamental theoretical basis of the HiTOP model by incorporating associations of temperament traits of two temperamental theories measured, respectively, by the Temperament and Character Inventory (TCI) and the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire (TEMPS-A) with (a) the FFM's personality domains and (b) HiTOP's five psychopathological spectra. Methods: A systematic search was done on Web of Science, Scopus, PubMed, ProQuest, Cochrane Database, and Google Scholar for all articles published in English from January 1990 to August 2020. Because of heterogeneity in the results of almost 70% of studies, pooled estimates of correlation coefficients were calculated using the random-effects method. Risk of bias (low-quality studies) and publication bias are reported. Results: The pooled correlations obtained from the analysis of 35 studies showed that the temperamental profile associated with each FFM domain and HiTOP spectra is distinct. Specifically, TCI-harm avoidance (HA) and all TEMPS temperaments were more strongly related to neuroticism/internalizing, extraversion/low detachment, and conscientiousness/disinhibition. In contrast, TCI-novelty seeking was more strongly related to both disinhibited/antagonistic externalizing and thought disorder. Conclusions: A large body of research supports maladaptive variants of all FFM domains and some psychopathological spectra of HiTOP related to the abnormal-range temperaments.

RESUMEN

This study investigates the personality traits and motivations of collaborationists with Russian invaders in Ukraine. A focus group of individuals who knew collaborationists personally identified 14 collaborationism motives (CMs), which were used to interview 104 probation clients convicted of collaborationism. The study utilized the five-factor model developed by Costa and McCrae to evaluate individual characteristics. Categorical principal component analysis (CATPCA) reduced the 14 CMs to three dimensions: pragmatism, adaptation, and fear. The study found that individual factors promoting collaborationism included pragmatism, ideological adaptation to changing realities, and fear stemming from threats to the life and health of an individual and/or their relatives. The study provides insights into the psychology of collaborationism, which can be useful in designing resocialization programs during the probation period of collaborationists.

RESUMEN

AIM: The surgeon's personality contributes to variation in surgical decision-making. Previous work on surgeon personality has largely been reserved to Anglo-Saxon studies, with limited international comparisons. In this work we built upon recent work on gastrointestinal surgeon personality and aimed to detect international variations. METHOD: Gastrointestinal surgeons from the UK and the Netherlands were invited to participate in validated personality assessments (44-item, 60-item Big Five Inventory; BFI). These encompass personality using five domains (open-mindedness, conscientiousness, extraversion, agreeableness and negative emotionality) with three subtraits each. Mean differences in domain factors were calculated between surgeon and nonsurgeon populations from normative data using independent-samples t-tests, adjusted for multiple testing. The items from the 44-item and 60-item BFI were compared between UK and Dutch surgeons and classified accordingly: identical (n = 16), analogous (n = 3), comparable (n = 12). RESULTS: UK (n = 78, 61.5% male) and Dutch (n = 280, 65% male) gastrointestinal surgeons had marked differences in the domains of open-mindedness, extraversion and agreeableness compared with national normative datasets. Moreover, although surgeons had similar levels of emotional stability, country of work influenced differences in specific BFI items. For example, Netherlands-based surgeons scored highly on questions related to sociability and organization versus UK-based surgeons who scored highly on creative imagination (p < 0.0001). CONCLUSION: In a first cross-cultural setting, we identified country-specific personality differences in gastrointestinal surgeon cohorts across domain and facet levels. Given the variation between Dutch and UK surgeons, understanding country-specific data could be useful in guiding personality research in healthcare. Furthermore, we advocate that future work adopts consensus usage of the five factor model.

RESUMEN

Hay un creciente interés por entender los trastornos de la personalidad (TTPP) desde el modelo de los cinco factores. Miller et al. (2005) y Costa y McCrae (2005) propusieron dos conjuntos de escalas basadas en las facetas del “Inventario de personalidad NEO-revisado” (NEO PI-R) para evaluar los TTPP del DSM-5. Existen baremos españoles para las escalas de Miller et al. (2005) a partir de muestras de selección de personal, pero no son apropiados en contextos con deseabilidad social baja. Se presentan datos normativos, de fiabilidad y validez convergente/ discriminante para ambos conjuntos de escalas con voluntarios de la población general española (N= 682). Los índices de consistencia interna y validez convergente/ discriminante fueron excelentes o buenos para todas las escalas, especialmente para las de Miller et al. (2005). Las diferencias entre la muestra de voluntarios y de selección de personal (d= 0,61) y entre varones y mujeres (d= 0,34-0,38) justifican el desarrollo de baremos para los dos conjuntos de escalas de TTPP para situaciones de deseabilidad social baja y separados por sexo. Se discute su utilidad en diferentes contextos.(AU)


There is increasing interest in understanding personality disorders (PDs) fromthe five-factor model. Miller et al. (2005) and Costa and McCrae (2005) proposedtwo sets of scales based on the NEO Personality Inventory-Revised (NEO PI-R) facetsto assess DSM-5 PDs. There are Spanish norms for the scales of Miller et al. (2005)based on personnel selection samples, but they are not appropriate for contextswith low social desirability. Normative, reliability, and convergent/discriminantvalidity data are presented for both sets of scales with volunteers from the generalSpanish population (N= 682). The internal consistency and convergent/discriminantvalidity indices were excellent or good for all scales, especially for those of Miller etal. (2005). The differences between the sample of volunteers and that of personnelselection (d= 0.61) and between males and females (d= 0.34-0.38) justify the development of norms for the two sets of PD scales for situations of low socialdesirability and separate for males and females. Their usefulness in differentcontexts is discussed.(AU)

RESUMEN

BACKGROUND: This study examined the influence of personality traits on (subclinical) positive symptom distress in patients with a psychotic disorder, their unaffected siblings and healthy controls. METHODS: Data were obtained from the Genetic Risk and Outcome of Psychosis study (GROUP), a Dutch longitudinal multicenter cohort study. Data from 140 patients, 216 unaffected siblings and 102 healthy controls was available for baseline levels of Five Factor Model personality traits and frequency and distress due to psychotic experiences three years later, assessed with the Community Assessment of Psychic Experience questionnaire. Main effects of all five personality traits on symptom distress were investigated as well as moderating effects of Neuroticism, Extraversion and Openness on positive symptom frequency and positive symptom distress. Age, gender, symptom frequency and IQ were controlled for. RESULTS: In both patients and siblings, the observed main effects of Neuroticism and Openness on (subclinical) positive symptom distress three years later either lost significance or had a very small effect size when controlling for covariates, mainly due to the correction for the effect of positive symptoms on personality traits at baseline. In both groups, levels of Openness at baseline moderated the association between positive symptom frequency and positive symptom distress three years later, in the direction that higher levels of Openness were associated with weaker associations between positive symptom frequency and - distress, even when covariates were controlled for. DISCUSSION: The level of Openness to Experiences influences the perceived distress from (subclinical) positive symptoms in both patients and siblings.

RESUMEN

INTRODUCTION: Substance 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. METHODS: Treatment-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. RESULTS: Neuroticism (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. CONCLUSION: Personality 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.

RESUMEN

After over a hundred years of research, the question whether the symptoms of schizophrenia are rather trait-like (being a relatively stable quality of individuals) or state-like (being substance to change) is still unanswered. To assess the trait and the state component in patients with acute schizophrenia, one group receiving antipsychotic treatment, the other not. Data from four phase II/III, 6-week, randomized, double-blind, placebo-controlled trials of similar design that included patients with acute exacerbation of schizophrenia were pooled. In every trial, one treatment group received a third-generation antipsychotic, cariprazine, and the other group placebo. To assess symptoms of schizophrenia, the Positive and Negative Symptom Scale (PANSS) was applied. Further analyses were conducted using the five subscales as proposed by Wallwork and colleagues. A latent state-trait (LST) model was developed to estimate the trait and state components of the total variance of the observed scores. All symptom dimensions behaved more in a trait-like manner. The proportions of all sources of variability changed over the course of the observational period, with a bent around weeks 3 and 4. Visually inspected, no major differences were found between the two treatment groups regarding the LST structure of symptom dimensions. This high proportion of inter-individual stability may represent an inherent part of symptomatology that behaves independently from treatment status.

RESUMEN

The main aim of this study was to analyse associations between the five-factor model personality traits and locus of control of successes and failures based on the theory of social learning and to assess whether gender moderated relationships between these variables in Polish early adolescents. The following instruments were used: the Picture Based Personality Survey for Children and the Locus of Control Questionnaire. A total of 1016 students participated in the study, including 49% boys and 51% girls. Both for girls and boys, the highest correlations were found between conscientiousness and locus of control in success situations. Neuroticism correlated negatively with the two types of locus of control. A moderating effect of gender was observed between openness to experience and locus of control of successes, and it was stronger in girls than in boys.

RESUMEN

This study examines the association between personality and cognitive errors in the Healthy Aging in Neighborhoods of Diversity across the Life Span study, a sample diverse across race (Black, White) and SES (above, below 125% of the federal poverty line). Participants (N=1,062) completed a comprehensive personality questionnaire and were administered a brief mental status screener of cognitive errors. Higher neuroticism was associated with more cognitive errors, whereas higher openness and conscientiousness were associated with fewer errors. These associations were independent of age, sex, race, poverty status, and education and were generally not moderated by these factors. These findings support the associations between personality and cognition across race and SES.

RESUMEN

OBJECTIVES: A barrier to seeking mental health care is treatment stigma, a form of stigma associated with seeking/receiving mental health treatment. Prior research has also demonstrated relationships between five-factor model personality traits and treatment-seeking attitudes. However, findings in this area are mixed and research has tended not to include assessments of maladaptive personality traits outlined in the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition Section III: Emerging Measures and Models. The present study sought to examine relationships between maladaptive personality traits, treatment stigma, and treatment-seeking attitudes and behavior in an adult sample. METHODS: Participants (N = 500) completed a series of questionnaires assessing current and past mental health treatment-seeking behaviors, treatment stigma, attitudes toward treatment seeking, and maldaptive personality traits. RESULTS: Results revealed all five maladaptive personality traits were positively associated with increased treatment stigma, and in models controlling for the shared variance across maladaptive personality traits, negative affect, antagonism, psychoticism, and stigma exhibited unique associations with one's perceived value and need of mental health treatment, whereas negative affect, detachment, and stigma were uniquely associated with openness to seeking mental health treatment for emotional problems. While the five maladaptive personality traits were associated with a history of treatment-seeking behaviors at the bivariate level and after controlling for stigma, only negative affect was uniquely associated with treatment-seeking behaviors in a model including all five personality trait domains. Exploratory moderation analyses revealed associations between stigma and openness to seeking treatment varied as a function of maladaptive personality traits. CONCLUSIONS: This study extends prior research on the role of personality traits in understanding treatment-seeking attitudes and behaviors and may have clinical implications for the use of maladaptive personality trait screeners in practice.

RESUMEN

BACKGROUND: Psilocybin Therapy (PT) is being increasingly studied as a psychiatric intervention. Personality relates to mental health and can be used to probe the nature of PT's therapeutic action. METHODS: In a phase 2, double-blind, randomized, active comparator controlled trial involving patients with moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, over a core 6-week trial period. Five-Factor model personality domains, Big Five Aspect Scale Openness aspects, Absorption, and Impulsivity were measured at Baseline, Week 6, and Month 6 follow-up. RESULTS: PT was associated with decreases in neuroticism (B = -0.63), introversion (B = -0.38), disagreeableness (B = -0.47), impulsivity (B = -0.40), and increases in absorption (B = 0.32), conscientiousness (B = 0.30), and openness (B = 0.23) at week 6, with neuroticism (B = -0.47) and disagreeableness (B = -0.41) remaining decreased at month 6. Escitalopram Treatment (ET) was associated with decreases in neuroticism (B = -0.38), disagreeableness (B = -0.26), impulsivity (B = -0.35), and increases in openness (B = 0.28) at week 6, with neuroticism (B = -0.46) remaining decreased at month 6. No significant between-condition differences were observed. CONCLUSIONS: Personality changes across both conditions were in a direction consistent with improved mental health. With the possible exception of trait absorption, there were no compelling between-condition differences warranting conclusions regarding a selective action of PT (v. ET) on personality; however, post-ET changes in personality were significantly moderated by pre-trial positive expectancy for escitalopram, whereas expectancy did not moderate response to PT.

RESUMEN

Background: The Short Dark Tetrad (SD4) is a recently developed instrument for assessing the “dark” personality traits of psychopathy, narcissism, Machiavellianism, and sadism. We aimed to examine the SD4’s psychometric properties, adapting it into Spanish and exploring its structure, gender invariance, reliability, concurrent validity, and nomological network. Method: A sample of 668 adults (Mage = 26.36, SD = 10.64, 69.2% females) completed the SD4 and other self-report questionnaires. Results: The results demonstrated sound indices of reliability and concurrent validity, an adequate four-factor structure, and support for gender invariance. Furthermore, most of the findings about the nomological network were in line with prior hypotheses: All four SD4 scales were associated with low levels of agreeableness and antagonism; psychopathy was also related to low conscientiousness, disinhibition and impulse-control problems; narcissism was positively associated with extraversion and negatively associated with internalizing symptoms; Machiavellianism was uncorrelated with impulsivity- related problems, which made it distinct from the psychopathy profile; finally, sadism showed a similar pattern of associations to psychopathy, albeit less strongly linked to impulsivity problems and externalizing behavior. Conclusions: Overall, the SD4 presents sound psychometric properties, although the overlap between psychopathy and sadism warrants some caution.(AU)


Antecedentes: El Short Dark Tetrad (SD4) es un instrumento recientemente desarrollado para evaluar los rasgos “oscuros” de personalidad de psicopatía, narcisismo, maquiavelismo y sadismo. Nuestro objetivo fue profundizar en las propiedades psicométricas del SD4 adaptando el instrumento al español, y examinar su estructura, invariancia de género, fiabilidad, validez concurrente y red nomológica. Método: Una muestra de 668 adultos (Medad = 26,36, SD = 10,64, 69,2% mujeres) completaron el SD4 y otros cuestionarios. Resultados: Encontramos índices apropiados de fiabilidad y validez concurrente, una estructura de cuatro factores, y apoyo a la invariancia de género. Además, los hallazgos sobre la red nomológica estuvieron mayoritariamente en línea con las hipótesis prerregistradas: las cuatro escalas SD4 se asociaron con baja amabilidad y antagonismo; la psicopatía se relacionó con baja responsabilidad, desinhibición y problemas de impulsividad; el narcisismo se asoció con extraversión y negativamente con síntomas de interiorización; el maquiavelismo no correlacionó con problemas de impulsividad, por lo que mostró un perfil diferenciado al de psicopatía; el sadismo mostró un patrón de asociaciones similar a psicopatía, aunque menos vinculado a problemas de impulsividad y comportamientos externalizantes. Conclusiones: En general, el SD4 presenta buenas propiedades psicométricas, aunque el solapamiento entre psicopatía y sadismo justifica cierta precaución.(AU)

RESUMEN

BACKGROUND: Opioid use disorder (OUD) is a heterogeneous disorder. However, there is a lack of deep phenotyping investigations focusing on important psychological constructs such as resilience that may impact OUD. The present study aimed to investigate the relationship between trait resilience and the five-factor model of personality (FFM) among individuals with opioid use disorder (OUD). We also explored whether the FFM and trait resilience form specific phenotypes associated with psychological functioning. METHODS: This secondary analysis of an epigenetic study included participants of African ancestry (n = 72), an understudied population, who met DSM-5 criteria for OUD. Participants completed measures to assess personality traits, trait resilience, current and previous drug use, and psychological functioning (depression, anxiety, and stress). RESULTS: Linear regression revealed a significant relationship between resilience (CD-RISC-25 score) and the FFM, R2 = 0.56, F(5,62) = 15.7, p<.001. Further, a two-cluster classification emerged as the optimal solution from the cluster analysis. Cluster 1 (n = 33, 45.8% of the sample) showed lower resilience (CD-RISC-25 score: M = 58.6, SD = 11.2) compared to Cluster 2 (n = 35, 48.6%; CD-RISC-25 score: M = 76.1, SD = 11.9). The "High-Resilience Cluster" (Cluster 2) was characterized by higher FFM traits of: Extraversion, Openness, Agreeableness, and Conscientiousness, and lower Neuroticism versus Cluster 1. Multivariate analysis of variance revealed statistically significant differences between the two resilience clusters concerning other psychological symptoms, Λ = 0.732, F(4, 50) = 7.05, p < 0.003. CONCLUSIONS: These findings suggest associations between the FFM and trait resilience among individuals with OUD. Two distinct "resilience phenotypes" emerged, with high-resilience individuals displaying less stress, anxiety, and depressive symptoms. Results highlight the clinical importance of resilience as a potential target for intervention in people with OUD.

RESUMEN

BACKGROUND: The conceptualization of negative symptoms (NS) in schizophrenia is still controversial. Recent confirmatory factor-analytic studies suggested that the bi-dimensional model (motivational deficit [MAP] and expressive deficit [EXP]) may not capture the complexity of NS structure, which could be better defined by a five-factor (five NS domains) or a hierarchical model (five NS domains as first-order factors, and MAP and EXP, as second-order factors). A validation of these models is needed to define the structure of NS. To evaluate the validity and temporal stability of the five-factor or the hierarchical structure of the brief negative symptom scale (BNSS) in individuals with schizophrenia (SCZ), exploring associations between these models with cognition, social cognition, functional capacity, and functioning at baseline and at 4 years follow-up. METHODS: Clinical variables were assessed using state-of-the-art tools in 612 SCZ at two-time points. The validity of the five-factor and the hierarchical models was analyzed through structural equation models. RESULTS: The two models had both a good fit and showed a similar pattern of associations with external validators at the two-time points, with minor variations. The five-factor solution had a slightly better fit. The associations with external validators favored the five-factor structure. CONCLUSIONS: Our findings suggest that both five-factor and hierarchical models provide a valid conceptualization of NS in relation to external variables and that five-factor solution provides the best balance between parsimony and granularity to summarize the BNSS structure. This finding has important implications for the study of pathophysiological mechanisms and the development of new treatments.

RESUMEN

The current study sought to provide evidence for a measure of schizoid personality disorder (SZD PD) traits using the Five-Factor Model framework of personality. In the first study, undergraduate participants (n = 496) completed the Five-Factor Schizoid Inventory (FFZI) and other self-report measures. The first half of the sample was used to develop the FFZI, while the second half was used to validate it. The FFZI demonstrated excellent internal consistency, convergent validity with measures of SZD PD and hypothesized IPIP-NEO facets, and discriminant validity with other PDs and non-hypothesized IPIP-NEO facets. The second study recruited MTurk participants (n = 181) and demonstrated preliminary support for the reliability and validity of the FFZI in an online, community sample. Ultimately, these data suggest that the FFZI is a useful measure of SZD PD and provide further evidence that SZD PD can be conceptualized as a maladaptive extension of introversion traits.

RESUMEN

Older adults need to participate in the digital society, as societal and personal changes and what they do with the remaining time that they have in their older years has an undeniable effect on motivation, cognition and emotion. Changes in personality traits were investigated in older adults over the period 2019-2021. Technology enthusiasm and technology anxiety are attitudes that affect the relationship to the technology used. The changes in the score of technology enthusiasm and technology anxiety were the dependent variables. They were investigated with personality traits, age, gender, education, whether someone lives alone, cognitive function, digital social participation (DSP) and health literacy as predictors of the outcome. The Edwards-Nunnally index and logistic regression were used. The results indicated that DSP, lower age, lower neuroticism and higher education were indicative of less technology anxiety. High DSP and high extraversion are indicative of technology enthusiasm. DSP and attitude towards technology seem to be key in getting older adults to stay active online.

RESUMEN

Recent studies have revived the issue of whether the five-factor personality model or Big Five is the most valid to summarize the most relevant personality traits or whether, on the contrary, the basic structure of personality traits would better fit a six-factor model such as the HEXACO model: Honesty-Humility (H), Emotionality (E), Extraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). In a Spanish community sample of 682 adults, the factorial structure of the 30 facets of the NEO-Revised Personality Inventory (NEO PI-R) and its 16 facets common to the HEXACO model was analyzed. In two subsamples of participants, the internal structure of the NEO PI-R, of 30 and 16 facets, fit the five-factor Big Five model better than the six-factor HEXACO model. In addition, the internal 30-facet structure of the NEO-PI-R replicated that obtained in the original US validation and those previously obtained in Spain, although the latter used different participant samples (people evaluated in personnel selection processes, university students). These results suggest that, at least in Spain, the five-factor personality model or Big Five is still the most valid taxonomy of personality traits.

This study explores the intriguing relationship between personality traits, self-rated fitness (SRF), and physical activity (PA) variables among German university students (N = 4244) and sheds light on the impact of personality on adherence to PA guidelines. Employing an online cross-sectional study, the short-form of the Big Five Inventory-2 assessed five domains of personality traits (Extraversion, Negative Emotionality, Agreeableness, Conscientiousness, and Open-Mindedness). PA, including sitting time, was assessed using the International Physical Activity Questionnaire (short-form). SRF and muscle-strengthening activities (MSA) were assessed with one item each. Multiple linear and logistic regression analyses examined associations of individual personality trait domains and all domains combined with SFR, PA variables, and adherence to PA guidelines, controlling for sociodemographic, behavioral, and (mental) health covariates. Most reliably, Extraversion and Conscientiousness revealed positive associations with PA variables, while Negative Emotionality yielded inverse relationships with PA variables. For instance, each unit increase in Extraversion corresponded to an additional 17 min of weekly MSA. On the contrary, daily sitting time was unrelated to personality. Of note, high Open-Mindedness was associated with lower odds for adhering to current PA guidelines. The findings have implications for developing targeted interventions that promote a physically active lifestyle and support students' well-being and academic success.
