RESUMO

Despite the widespread use of the HEXACO model as a descriptive taxonomy of personality traits, there remains limited information on the test-retest reliability of its commonly-used inventories. Studies typically report internal consistency estimates, such as alpha or omega, but there are good reasons to believe that these do not accurately assess reliability. We report 13-day test-retest correlations of the 100- and 60-item English HEXACO Personality Inventory-Revised (HEXACO-100 and HEXACO-60) domains, facets, and items. In order to test the validity of test-retest reliability, we then compare these estimates to correlations between self- and informant-reports (i.e., cross-rater agreement), a widely-used validity criterion. Median estimates of test-retest reliability were .88, .81, and .65 (N = 416) for domains, facets, and items, respectively. Facets' and items' test-retest reliabilities were highly correlated with their cross-rater agreement estimates, whereas internal consistencies were not. Overall, the HEXACO Personality Inventory-Revised demonstrates test-retest reliability similar to other contemporary measures. We recommend that short-term retest reliability should be routinely calculated to assess reliability.

RESUMO

BACKGROUND/OBJECTIVES: Many personality traits correlate with BMI, but the existence and direction of causal links between them are unclear. If personality influences BMI, knowing this causal direction could inform weight management strategies. Knowing that BMI instead influences personality would contribute to a better understanding of the mechanisms of personality development and the possible psychological effects of weight change. We tested the existence and direction of causal links between BMI and personality. SUBJECTS/METHODS: We employed two genetically informed methods. In Mendelian randomization, allele scores were calculated to summarize genetic propensity for the personality traits neuroticism, worry, and depressive affect and used to predict BMI in an independent sample (N = 3 541). Similarly, an allele score for BMI was used to predict eating-specific and domain-general phenotypic personality scores (PPSs; aggregate scores of personality traits weighted by BMI). In a direction of causation (DoC) analysis, twin data from five countries (N = 5424) were used to assess the fit of four alternative models: PPSs influencing BMI, BMI influencing PPSs, reciprocal causation, and no causation. RESULTS: In Mendelian randomization, the allele score for BMI predicted domain-general (ß = 0.05; 95% CI: 0.02, 0.08; P = 0.003) and eating-specific PPS (ß = 0.06; 95% CI: 0.03, 0.09; P < 0.001). The allele score for worry also predicted BMI (ß = -0.05; 95% CI: -0.08, -0.02; P < 0.001), while those for neuroticism and depressive affect did not (P ≥ 0.459). In DoC, BMI similarly predicted domain-general (ß = 0.21; 95% CI:, 0.18, 0.24; P < 0.001) and eating-specific personality traits (ß = 0.19; 95% CI:, 0.16, 0.22; P < 0.001), suggesting causality from BMI to personality traits. In exploratory analyses, links between BMI and domain-general personality traits appeared reciprocal for higher-weight individuals (BMI > ~25). CONCLUSIONS: Although both genetic analyses suggested an influence of BMI on personality traits, it is not yet known if weight management interventions could influence personality. Personality traits may influence BMI in turn, but effects in this direction appeared weaker.

RESUMO

BACKGROUND: Greater neuroticism has been associated with higher risk for Alzheimer's disease (AD) dementia. However, the directionality of this association is unclear. We examined whether personality traits differ between cognitively-unimpaired carriers of autosomal-dominant AD (ADAD) and non-carriers, and are associated with in vivo AD pathology. OBJECTIVE: To determine whether personality traits differ between cognitively unimpaired ADAD mutation carriers and non-carriers, and whether the traits are related to age and AD biomarkers. METHODS: A total of 33 cognitively-unimpaired Presenilin-1 E280A mutation carriers and 41 non-carriers (ages 27-46) completed neuropsychological testing and the NEO Five-Factor Personality Inventory. A subsample (n = 46; 20 carriers) also underwent tau and amyloid PET imaging. RESULTS: Carriers reported higher neuroticism relative to non-carriers, although this difference was not significant after controlling for sex. Neuroticism was positively correlated with entorhinal tau levels only in carriers, but not with amyloid levels. CONCLUSION: The finding of higher neuroticism in carriers and the association of this trait with tau pathology in preclinical stages of AD highlights the importance of including personality measures in the evaluation of individuals at increased risk for cognitive impairment and dementia. Further research is needed to characterize the mechanisms of these relationships.

RESUMO

The Severity Indices of Personality Problems (SIPP; Verheul et al., 2008) is a popular self-report questionnaire that measures severity of maladaptive personality functioning. Two studies demonstrated the utility of the short form (SIPP-SF) among older adults but validation in clinical settings is lacking. Therefore, we examined the psychometric properties of the SIPP-SF in a large sample of older adult Dutch outpatients (N = 124; age range = 60-85 years, M = 69.8, SD = 5.3). The SIPP-SF domains showed good to excellent internal reliability (Cronbach's α = .75-.91) and effectively discriminated between participants with and without a personality disorder, as assessed with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II). Convergent validity of the SIPP-SF was examined with instruments for measuring personality pathology among older adults (Informant Personality questionnaire [HAP]; Gerontological Personality Disorders Scale [GPS]). The GPS generally correlated with the SIPP-SF domains in expected directions, with small to large effect sizes. For the HAP, only 1 scale correlated with all SIPP-SF domains. No associations were found between the SIPP-SF and psychiatric symptomatology as measured by the Brief Symptom Inventory (BSI). The SIPP-SF appears to be a promising instrument for assessing maladaptive personality functioning among older adult outpatients.

RESUMO

The European Higher Education Area was implemented more than a decade ago with the aim of improving internationally the competitiveness of European university education putting the spotlight on skills and competence development (and not only on knowledge acquisition). This work intends to analyze the impact of competence-based teaching methodologies on university students, as well as to contribute to the study of the individual personality traits differences regarding this impact. For this, a descriptive, quantitative, cross-sectional study was conducted with a non-randomised sample of university students. The sample was composed of a total of 499 students of the University of Huelva (350 from the Health Sciences degree, and 149 form other degrees), who completed a questionnaire on professional skills and teaching methods developed ad hoc for this research, as well as the brief version of the Spanish adaptation of the NEO Five-Factor Inventory. The results show that Health Sciences students feel more satisfied with the most participative and active methodologies, and they consider these better contribute to their future professional competence development. On the other hand, in relation to the big 5 personality traits studied, links have been found between competence development perception and personal preferences and the dimensions of extraversion, agreeableness, conscientiousness and openness to experience. This last factor, openness to experience, appears when analyzing the main differences among both groups, being Health Sciences students more intellectually curious, showing more openness and diversity of interests, in addition to being more creative, innovative, and flexible.

RESUMO

Psychological theories often produce hypotheses that pertain to individual differences in within-person variability. To empirically test the predictions entailed by such hypotheses with longitudinal data, researchers often use multilevel approaches that allow them to model between-person differences in the mean level of a certain variable and the residual within-person variance. Currently, these approaches can be applied only when the data stem from a single variable. However, it is common practice in psychology to assess not just a single measure but rather several measures of a construct. In this paper we describe a model in which we combine the single-indicator model with confirmatory factor analysis. The new model allows individual differences in latent mean-level factors and latent within-person variability factors to be estimated. Furthermore, we show how the model's parameters can be estimated with a maximum likelihood estimator, and we illustrate the approach using an example that involves intensive longitudinal data.

RESUMO

The Child Problematic Traits Inventory (CPTI) is a newly developed informant-rated instrument to measure psychopathic traits during early childhood. The aim of this study was to examine the longitudinal measurement invariance of the CPTI in a group of Chinese schoolchildren. Mothers of 585 children aged 8 to 12 years (50% girls) completed the CPTI twice with one-year interval. Confirmatory factor analyses showed that the CPTI had strict invariance (i.e., equality of factor patterns, loadings, intercepts, and item uniqueness) across time. Furthermore, the internal consistencies for the CPTI subscales were good at both time points and the stability coefficients over time were moderate. Findings suggest that, in children aged 8 to 12 years old, changes in CPTI scores across time can be attributed to actual changes in the child's psychopathic personality.

RESUMO

BACKGROUND: In literature, there are many instruments for evaluating workaholism; however, they do not have convergent validity, because of the lack of a shared definition of workaholism. OBJECTIVE: We propose a new instrument for evaluating workaholism and work engagement, namely the Work-related Inventory (WI-10), which is based on Loscalzo and Giannini's (2017) comprehensive definition of workaholism. METHODS: We developed a pool of 36 items, covering: 1) addiction symptoms; 2) obsessive-compulsive symptoms, and 3) work engagement. Then, we conducted Exploratory and Confirmatory Factor analyses on a sample of 503 Italian workers (165 males, 337 females, one missing; Mean age = 38.26±10.84) aiming to reduce the number of items. RESULTS: The results showed a 10-items (2 filler) and 2-factor solution: 1) Workaholism and 2) Work Engagement; moreover, the WI-10 has good internal reliability, convergent and divergent validity. CONCLUSIONS: We found good psychometric properties for the WI-10. We also proposed the cut-off scores for the screening of the four kinds of workers proposed by Loscalzo and Giannini (2017): disengaged workaholics, engaged workaholics, engaged workers, and detached workers. The WI-10 will be useful for both research and preventive and clinical purposes.

RESUMO

It is commonly accepted that gathering information via multiple assessment methods (e.g., interview and questionnaire, self- and informant report) is important for establishing construct validity. Although numerous articles report convergent and discriminant agreement correlations between self- and other ratings of personality, studies of the structure of personality from such ratings are less common. The present study addresses this gap using a meta-analytic data set (N range = 157-9,295) of various versions (i.e., self- and other-report, full-length and short alternative format) of the Schedule for Nonadaptive and Adaptive Personality (SNAP; Clark, 1993; Clark, Simms, Wu, & Casillas, 2014). We hypothesized that (a) structures across all measure formats would be highly comparable and (b) to the extent that they were dissimilar, perspective (self vs. other) and measure format (long vs. short form), respectively, would influence comparability. Results revealed strong congruence among 3-factor structures (Negative Emotionality, Positive Emotionality, and Disinhibition vs. Constraint) across all versions of the SNAP, suggesting that personality as assessed by this broad measure of personality traits across the normal-abnormal spectrum has a robust structure across different rater perspectives and rating formats. Because the comparability analyses were highly congruent and differences among the comparisons were minimal, we concluded-contrary to our expectations-that different formats and different rater perspectives have little effect on structural comparability. Results generally support Funder's (1995) realistic accuracy model, suggesting that trait relevance, cue detection, and information usage are key factors in structuring informant ratings. Limitations of the present study and implications for future research are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

RESUMO

Mõttus and colleagues (2017) reported evidence that the unique variance in specific personality characteristics captured by single descriptive items often displayed trait-like properties of cross-rater agreement, rank-order stability, and heritability. They suggested that the personality hierarchy should be extended below facets to incorporate these specific characteristics, called personality nuances. The present study attempted to replicate these findings, employing data from 6,287 individuals from 6 countries (Australia, Canada, Czech Republic, Denmark, Japan, and United States). The same personality measure-240-item Revised NEO Personality Inventory-and statistical procedures were used. The present findings closely replicated the original results. When the original and current results were meta-analyzed, the unique variance of nearly all items (i.e., items' scores residualized for all broader personality traits) showed statistically significant cross-rater agreement (median = .12) and rank-order stability over an average of 12 years (median = .24), and the unique variance of the majority of items had a significant heritable component (median = .14). These 3 item properties were intercorrelated, suggesting that items systematically differed in the degree of reflecting valid unique variance. Also, associations of items' unique variance with age, gender, and body mass index (BMI) replicated across samples and tracked with the original findings. Moreover, associations between item residuals and BMI obtained from one group of people allowed for a significant incremental prediction of BMI in an independent sample. Overall, these findings reinforce the hypotheses that nuances constitute the building blocks of the personality trait hierarchy, their properties are robust and they can be useful.

RESUMO

BACKGROUND: The Big Five framework examines five factors that represent a description of human personality. These factors correlate with success measures and job satisfaction. The Big Five Inventory is a 44-item instrument designed to measure the Big Five framework. Our aim was to document the distribution of Big Five personality traits among Pediatric Surgery fellowship applicants, compare with community norms, surgical residents, between genders, and correlate to the fellowship match results. MATERIALS AND METHODS: Forty Pediatric Surgery fellowship applicants at a university hospital completed the Big Five Inventory during the interview process. It was analyzed and compared with general surgery residents' results and community norms. The data were compared regarding gender and match results. Continuous variables were compared by unpaired t-tests and Mann-Whitney tests. A P value <0.05 was considered significant. RESULTS: The 40 applicants were equally divided between male and female. When compared with general surgery residents and community norms, applicants of both genders scored higher on agreeableness (P < 0.01), conscientiousness (P < 0.01), and emotional stability (P < 0.01). Applicants scored higher on openness when compared with surgical residents (P < 0.01). Male applicants scored higher on emotional stability than females (P = 0.026). Matched applicants scored higher for conscientiousness than unmatched applicants (P = 0.016). CONCLUSIONS: Pediatric Surgery fellowship applicants expressed higher levels of desirable professional traits compared with general surgery residents and community norms. Male applicants demonstrated higher emotional stability than females. Conscientiousness was higher in matching applicants. This first reported experience with personality testing in Pediatric Surgery fellow selection demonstrated potential utility in applicant matching.

RESUMO

Many argue that current categorical personality disorder (PD) classification systems should be more dimensional and consider personality traits. The present study examined whether a brief PD screening tool, the Standardized Assessment of Personality: Abbreviated Scale (SAPAS) primarily screened for traits of low emotional stability, low extraversion, and low agreeableness, rather than PD per se. A general community sample (n = 237) completed the SAPAS, a personality trait measure, and the International Personality Disorder Examination (IPDE) screening questionnaire. Regressions showed that the SAPAS provided substantial incremental validity over personality trait scores in predicting total IPDE scores, indicating that the SAPAS captures variance unique to PD, rather than just extremes of general disposition. The SAPAS is an empirically valid rapid PD screen for nonclinical populations, correctly identifying 78% of individuals who screen positively for PD on the IPDE. However, the SAPAS was not effective for screening antisocial PD, limiting its utility in forensic settings.

RESUMO

BACKGROUND: Working in anaesthesia is stressful, but also satisfying. Work-related stress can have a negative impact on mental health, whereas work-related satisfaction protects against these harmful effects. OBJECTIVE(S): How work stress and satisfaction are experienced may be related to personality. Our aim was to study the relationship between personality and perception of work in a sample of Dutch anaesthesiologists. DESIGN: Questionnaire survey. SETTING: Data were collected in the Netherlands from July 2012 until December 2012. PARTICIPANTS: We sent electronic questionnaires to all 1955 practising resident and consultant members of the Dutch Anaesthesia Society. Of those, 655 (33.5%) were returned and could be used for analysis. MAIN OUTCOME MEASURES: The questionnaires assessed general work-related stress and satisfaction and anaesthesia-specific stress. A factor analysis was performed on the stress and satisfaction questionnaires. Personality traits were assessed using the Big Five Inventory. To identify personality profiles, a cluster analysis was performed on the Big Five Inventory. Scores of the extracted factors contributing to job stress and satisfaction were compared between the profiles we identified. RESULTS: Our analysis extracted six factors concerning general job stress. Of those, the emotionally difficult caseload contributed the most to job stress. The analysis also extracted four factors concerning general job satisfaction. Good relationships with patients and their families and being appreciated by colleagues contributed the most to satisfaction. The cluster analysis resulted in two distinct personality profiles: a distressed profile (n = 215) and a resilient profile (n = 440). General and anaesthesia-specific job stress was significantly higher and job satisfaction was significantly lower in the distressed profile, compared with the resilient profile. Experience of the emotionally difficult caseload did not differ between the two profiles CONCLUSION: Personality profiles were found to be related to anaesthesiologists' experience of work-related stress and satisfaction. One-third of the anaesthesiologists in our sample were categorised as distressed and are at risk of developing work-related mental health problems.

RESUMO

Stigma has received attention as a major barrier toward effective mental health service delivery, and previous research has demonstrated that the Five-Factor Model (FFM) domain of Openness to Experience is negatively correlated with stigmatized views of mental health. However, a lack of established relationships between personality and self-stigma, as well as how these concepts affect an individual's treatment-seeking intentions, has left a gap in the literature. To address this, our study recruited a low-income community sample and tested (a) the relationship between self-stigma of mental health treatment and the FFM, (b) the relationship between self-stigma and treatment-seeking intentions, and (c) the incremental validity of FFM personality beyond stigma in the prediction of treatment seeking. Results suggest that there is some incongruence with previous research on personality's relationship to stigma, personality does not act as an additive component in the prediction of the relationship between stigma and treatment seeking, and stigma is related only to the perceived need for mental health treatment but not to an individual's openness to seek that treatment. The discussion concludes with implications for the contextualization and treatment of stigma as a barrier for mental health treatment and a general synthesis of the personality trait profiles for those holding stigmatizing views of mental health.

RESUMO

Facial expressions are critical in forming social bonds and in signalling one's emotional state to others. In eating disorder patients, impairments in facial emotion recognition have been associated with eating psychopathology severity. Little research however has been carried out on how bulimic spectrum disorder (BSD) patients spontaneously express emotions. Our aim was to investigate emotion expression in BSD patients and to explore the influence of personality traits. Our study comprised 28 BSD women and 15 healthy controls. Facial expressions were recorded while participants played a serious video game. Expressions of anger and joy were used as outcome measures. Overall, BSD participants displayed less facial expressiveness than controls. Among BSD women, expressions of joy were positively associated with reward dependence, novelty seeking and self-directedness, whereas expressions of anger were associated with lower self-directedness. Our findings suggest that specific personality traits are associated with altered emotion facial expression in patients with BSD.

RESUMO

Recently, a phenotype of severe dysregulation, the Dysregulation Profile (DP), has been identified. DP consists of elevated scores on the Anxious/Depressed (AD), Aggressive Behavior (AGG) and Attention Problems (AP) scales of the Child Behavior Checklist (CBCL), Teacher Report Form (TRF), or Youth Self Report (YSR). A drawback in current research is that DP has been conceptualized and operationalized in different manners and research on the factor structure of DP is lacking. Therefore, we examined the factor structure of DP across multiple reporters, measurement invariance across gender, parents, and time, as well as links between DP and self-harm and suicidal ideation. Data from a large community sample were used (N = 697), covering middle childhood (Mage = 7.90, (SD = 1.16) and adolescence (Mage = 13.93, SD = 1.14). Mothers, fathers, teachers, and youth themselves reported on children's emotional and behavioral problems using the CBCL, TRF, and YSR. Results indicated that in middle childhood and in adolescence, a bifactor model with a general factor of Dysregulation alongside three specific factors of AD, AGG, and AP fitted best, compared to a second-order or one-factor model. The model showed good fit for mother, father, teacher, and youth reports and showed invariance across gender, parents and time. Youth, mother, and father reported Dysregulation was uniquely and positively related to adolescent-reported self-harm and suicidal ideation. The DP is best conceptualized as a broad dysregulation syndrome, which exists over and above anxiety/depression, aggression, and attention problems as specific problems. The bifactor model of DP explains the uniqueness and interrelatedness of these behavioral problems and can help explaining shared and non-shared etiology factors. The exclusive link between the general dysregulation factor and adolescents' self-harm and suicidal ideation further established the clinical relevance of the bifactor model.

RESUMO

A generalized linear modeling framework to the analysis of responses and response times is outlined. In this framework, referred to as bivariate generalized linear item response theory (B-GLIRT), separate generalized linear measurement models are specified for the responses and the response times that are subsequently linked by cross-relations. The cross-relations can take various forms. Here, we focus on cross-relations with a linear or interaction term for ability tests, and cross-relations with a curvilinear term for personality tests. In addition, we discuss how popular existing models from the psychometric literature are special cases in the B-GLIRT framework depending on restrictions in the cross-relation. This allows us to compare existing models conceptually and empirically. We discuss various extensions of the traditional models motivated by practical problems. We also illustrate the applicability of our approach using various real data examples, including data on personality and cognitive ability.

RESUMO

Faking, the intentional distortion of answers to personality tests, is likely a complex process. In particular, participants in previous research have mentioned that they used different kind of strategies to appear more hirable, including systematically more extreme or more midpoint responses. However, quantitative evidence is still lacking. An experiment was conducted in which 327 students (173 women, 153 men, 1 not indicated; M age = 22.1 yr., SD = 2.8) were randomly assigned to two groups. Hypothetical job advertisements primed the participants into believing that the hiring company preferred a person with either a "strong" (Strong Character group) or a "well-balanced" character (Well-balanced Character group). The participants filled out 40 items that were chosen from four established questionnaires as neither socially desirable nor undesirable. The responses to these items were used to calculate two extreme response measures and one midpoint response measure. The Strong Character group used extreme scores more often than the Well-balanced Character group (and the midpoint scores less often), independently of mean differences. This suggests that fakers use more sophisticated strategies than is often assumed.

RESUMO

Faking is a common problem in testing with self-report personality tests, especially in high-stakes situations. A possible way to correct for it is statistical control on the basis of social desirability scales. Two such scales were developed and applied in the present paper. It was stressed that the statistical models of faking need to be adapted to different properties of the personality scales, since such scales correlate with faking to different extents. In four empirical studies of self-report personality tests, correction for faking was investigated. One of the studies was experimental, and asked participants to fake or to be honest. In the other studies, job or school applicants were investigated. It was found that the approach to correct for effects of faking in self-report personality tests advocated in the paper removed a large share of the effects, about 90%. It was found in one study that faking varied as a function of degree of how important the consequences of test results could be expected to be, more high-stakes situations being associated with more faking. The latter finding is incompatible with the claim that social desirability scales measure a general personality trait. It is concluded that faking can be measured and that correction for faking, based on such measures, can be expected to remove about 90% of its effects.

RESUMO

Introduction: The Temperament & Personality Questionnaire (T&P) is a self-report instrument designed to evaluate personality styles overrepresented in patients with depression. This report briefly describes the translation and adaptation of the T&P into Brazilian Portuguese. Methods: The procedures, which included 10 steps, followed guidelines for the adaptation of self-report instruments defined by the International Society For Pharmacoeconomics and Outcomes Research (ISPOR) Task Force for Translation and Cultural Adaptation. Results: The author of the original T&P questionnaire authorized and participated in the translation conducted by the authors and independent native speakers. Evaluation of the translated questionnaire indicated that only minor adjustments were required in the Portuguese version. Conclusions: The Brazilian version of T&P, translated and adapted following a rigid standardized process, is available for use free of charge and may be especially useful in pursuing links between personality styles and depressive conditions (AU)


Introdução: O Temperament & Personality Questionnaire (T&P) é um instrumento de autorrelato criado para avaliar quais estilos de personalidade têm maior representação em pacientes com depressão. Este trabalho descreve brevemente o processo de tradução e adaptação do T&P para o português brasileiro. Métodos: A tradução e a adaptação cultural se desenvolveram em 10 passos e seguiram as diretrizes para adaptação de instrumentos de autorrelato definidas por força-tarefa do ISPOR (International Society For Pharmacoeconomics and Outcomes Research). Resultados: O autor do questionário T&P original autorizou e participou da tradução feita pelos autores e por falantes nativos independentes. A avaliação do questionário traduzido mostrou que apenas pequenos ajustes foram necessários na versão em português. Conclusões: A versão brasileira do questionário T&P, traduzido e adaptado seguindo um rígido processo padronizado, está disponível gratuitamente e pode ser de grande utilidade na pesquisa sobre as relações entre estilos de personalidade e quadros depressivos (AU)
