A Big Tent of Dark Personality Traits

Giving Meaning to the Dark Triad: Comparison of Different Factor Structures of the Dirty Dozen Through Eight Regions of the World

The traits of the dark triad (narcissism, psychopathy, and Machiavellianism) capture the individual differences in the aversive personality. The dark triad has shown significant relations with behaviors that affect people's lives. One of the best-known instruments to assess the dark triad is the Dirty Dozen. However, controversy continues over the use of one general dark triad score or, conversely, three different scores. This study aimed to investigate the factor structure of the Dirty Dozen across eight global regions. There were 11,477 participants in 49 countries grouped into eight regions. Different factor structures were studied using confirmatory factor analyses. Both the three-dimensional models and the bifactor models (symmetrical or traditional and non-symmetrical or bifactor-[S - 1]) showed a good fit to the data. The bifactor-(S - 1) models (with psychopathy or Machiavellianism as the reference factors) show adequate fit to the data, supported by the coherence of the factorial loadings and the bifactor indices. Regarding measurement invariance for both models, configural, metric, and scalar invariance were satisfied. The results indicate that it is not clear whether a psychopathy or Machiavellianism reference factor predominates in the Dirty Dozen. For both models, templates are provided to obtain standardized scores for applied researchers in the eight studied world regions until future studies offer a greater amount of validity evidence for this instrument.

Theoretical and Empirical Integration of "Dark" Traits and Socially Aversive Personality Psychopathology

Conceptual work integrating constructs from mainstream personality research (especially so-called "dark" traits) and clinical psychopathology research has been limited. Herein, we propose all socially and/or ethically aversive traits as "flavored" manifestations of the D factor of personality (D). We argue that the D framework provides the commonality of all aversive traits, including the aversive traits from the DSM-5 Alternative Model for Personality Disorders (AMPD), a more thorough theoretical foundation. Moreover, D covers aspects that are not captured by any of the aversive AMPD traits directly (e.g., greed), thus offering indications for possible expansions to the AMPD. We tested our predictions in two online studies (N = 1,781 and N = 2,006) using quota-representative samples of the German population regarding age and gender. Twelve aversive traits from mainstream personality research and eight aversive AMPD traits were assessed together with consequential behavior in an economic game. Analyses using structural equation modeling overall confirmed predictions.

Pet attachment and owner personality

Introduction

Research points to a relationship between owner personality and strength of attachment to one's pet, with implications for psychological health. So far, studies in this area, albeit sparse, have focused on the 'Big Five' traits of owner personality. The 'Dark Triad' is a cluster of traits that has also been linked to emotional deficits, but has been overlooked in relation to pet attachment. This study therefore examined the association between owner personality and pet attachment, focusing on both the 'Big Five' and 'Dark Triad' traits of personality.

Methods

A cross-sectional design was employed to collect quantitative data from dog and cat owners across the globe between May-June 2023. A purpose-designed online survey collected sociodemographic details, along with information on pet ownership, strength of the pet-owner bond and participant personality, assessed using the Big Five personality scale and the Short Dark Triad scale. The survey was fully completed by 759 dog and 179 cat owners.

Results

Analysis revealed significant correlations between many of the participants' personality traits, both within and between scales. Strength of pet attachment was positively correlated with neuroticism and conscientiousness, and, more weakly, to Machiavellianism. Regression analysis revealed that females, dog owners, people over the age of 50 and individuals who had children under 18 years to care for were more strongly attached to their pets than others. Both neuroticism and conscientiousness were found to be significant predictors of participants' pet attachment scores. None of the Dark Triad traits significantly predicted the criterion.

Discussion

This study points to a relationship between strength of attachment to one's pet and owner personality, at least as measured using the Big Five approach to personality assessment. There was little to support an association between the Dark Triad traits and strength of attachment to one's pet, although the link between these characteristics and attachment styles is still unknown. The investigation lends support for the idea that high attachment levels are associated with personality traits aligned to psychological ill-health. Further work is recommended in this area, with a greater focus on both strength and quality (e.g., attachment style) of the pet-owner bond.

Personality and motivation of physical activity in adolescent girls: effects of perceived parental support and social physical anxiety

In the present study, we investigated the relationship between personality and motivation for physical activity while introducing perceived parental support and social physical anxiety in adolescent girls (N = 318, Mage: 16.19 ± 0.51 years). The present study was a retrospective correlational study that was conducted to analyze of a path model. Dark triad traits: Machiavellianism, narcissism, and psychopathy, student's motivation for physical activity, social physique anxiety, and participants' perceptions of parents' behaviors were measured. The findings indicated that psychopathy and Machiavellianism were directly and indirectly associated with motivation for physical activity, but Narcissism could only directly predict the motivation for physical activity. Also, need-thwarting (the most), need-supportive and social physical anxiety could predict motivation for physical activity. This model of the result suggests that among adolescent girls, dark triad personality could, directly and indirectly, predict motivation with need-supportive and need-thwarting and also social physical anxiety. It seems that the sense of importance and more attention to oneself in adolescent girls, which exists in the narcissistic personality, can directly lead to more motivation for physical activity. Also, the duplicitous ways of Machiavellian people in pursuing their motives were confirmed in this research.

Individual differences in spite predict costly third-party punishment

OBJECTIVE

Spiteful behaviors are those aimed at inflicting harm on another person while also incurring a cost to the self. Although spite sometimes reflects destructive and socially undesirable behaviors including aggression, the current work sought to examine a potentially socially beneficial aspect of spite: engagement in costly punishment for selfish behavior.

METHOD

Four studies used a costly third-party punishment task and measured individual differences in spite, narcissism, Machiavellianism, psychopathy, and motivations for engaging in punishment.

RESULTS

Trait spite was positively associated with costly punishment of selfish behavior. That association was independent of other dark personality traits (narcissism, Machiavellianism, psychopathy) and was statistically mediated by a desire for retribution. One of the studies also provided evidence that trait spite was associated with costly punishment of even generous behavior; however, rather than a desire for retribution, that association was mediated by a desire to threaten the person being punished.

CONCLUSION

Punishing selfishness and other forms of wrongdoing plays an essential role in cooperative group living. The current work provides new insight into the role spiteful motivations might play in this crucial social behavior.

Dark-ego-vehicle principle: Narcissism as a predictor of anti-sexual assault activism

In this preregistered study, we tested the dark-ego-vehicle principle. This principle states that individuals with dark personalities, such as high narcissistic traits, are inclined to become involved in certain kinds of ideologies and political activism. We argue that narcissistic individuals can be attracted to anti-sexual assault activism because this form of activism may provide them with opportunities to obtain positive self-presentation (e.g., virtue signaling), gain status, dominate others, and engage in social conflicts to get their thrills. A diverse US sample (N = 313) completed online measures of narcissistic traits and involvement in anti-sexual assault activism. In addition, relevant covariates were assessed (i.e., age, gender, adult sexual assault history, sexual harassment myth acceptance, and altruism), and the interaction between narcissistic traits and gender was considered. The results of the multiple regression analysis showed that higher narcissistic traits predicted an individual’s higher involvement in anti-sexual assault activism over and above the covariates. However, this relationship was evident only for the women in this sample. Notably, a higher level of altruism in an individual was also substantially associated with higher involvement in anti-sexual assault activism. We discuss how the narcissism-by-gender interaction may be in line with the dark-ego-vehicle principle.

Development and Initial Validation of Two Brief Measures of Left-Wing Authoritarianism: A Machine Learning Approach

Although authoritarianism has predominantly been studied among political conservatives, authoritarian individuals exist on both "poles" of the political spectrum. A 39-item multidimensional measure of left-wing authoritarianism, the Left-wing Authoritarianism Index, was recently developed to extend the study of authoritarianism to members of the far-left. The present study coupled a fully automated machine learning approach (i.e., a genetic algorithm) with multidimensional item response theory in a large, demographically representative American sample (N = 834) to generate and evaluate two abbreviated versions of the Left-wing Authoritarianism Index. We subsequently used a second community sample (N = 477) to conduct extensive validational tests of the abbreviated measures, which comprise 25- and 13-items. The abbreviated forms demonstrated remarkable convergence with the full LWA Index in terms of their psychometric (e.g., internal consistency) and distributional (e.g., mean, standard deviation, skew, kurtosis) properties. This convergence extended to virtually identical cross-measure patterns of correlations with 14 external criteria, including need for chaos, political violence, anomia, low institutional trust. In light of these results, the LWA-25 and LWA-13 scales appeared to function effectively as measures of LWA.

The Dispositional Essence of Proactive Social Preferences: The Dark Core of Personality vis-à-vis 58 Traits

Individuals differ in how they weigh their own utility versus others'. This tendency codefines the dark factor of personality (D), which is conceptualized as the underlying disposition from which all socially and ethically aversive (dark) traits arise as specific, flavored manifestations. We scrutinize this unique theoretical notion by testing, for a broad set of 58 different traits and related constructs, whether any predict how individuals weigh their own versus others' utility in proactive allocation decisions (i.e., social value orientations) beyond D. These traits and constructs range from broad dimensions (e.g., agreeableness), to aversive traits (e.g., sadism) and beliefs (e.g., normlessness), to prosocial tendencies (e.g., compassion). In a large-scale longitudinal study involving the assessment of consequential choices (median N = 2,270; a heterogeneous adult community sample from Germany), results from several hundred latent model comparisons revealed that no meaningful incremental variance was explained beyond D. Thus, D alone is sufficient to represent the social preferences inherent in socially and ethically aversive personality traits.

Development and validation of Chinese form Short Dark Tetrad (C-SD4)

The Short Dark Tetrad (SD4) was developed as a brief measure of the Dark Tetrad, which comprises narcissism, Machiavellianism, psychopathy, and sadism. Previous research suggests the possibility of cultural differences in these traits in Western and Eastern cultures. We developed and validated the Chinese form of SD4 (C-SD4) cross four studies in a large sample (total N = 3181) to assist in solving problems caused by these differences. In study 1, we adjusted the item pool on the basis of the original form of SD4. In Study 2, we trimmed the scale to generate a 28-item version of C-SD4 and examined correlations with Big-5. In study 3, we examined the internal structure, measurement invariance, and criterion validity of the C-SD4. In study 4 we examined C-SD4 test-retest reliability and compared item content to standard measures. This package of studies suggests that the C-SD4 is a reliable and valid measure of the Dark Tetrad in Chinese participants.

Item Response Theory Analysis of the Dark Factor of Personality Scale for College Students in China

The Dark Factor of Personality (D) describes the common core of dark traits and is a stable indicator for socially aversive behaviors. This study investigated the psychometric properties of the Chinese version of the Dark Factor of Personality Scale for college students using item response theory (IRT). A total of 762 students-251 males and 511 females (M = 19.99, SD = 1.30)-were recruited. Item response theory methods were utilized to evaluate the properties of the scale. Four items with poor item properties were excluded, obtaining a final 28-item scale (D28-C) that included highly discriminative items showing high measurement precision in various levels of the D factor. Furthermore, a test of differential item functioning (DIF) by gender was conducted. The result indicated that the scale as a whole could be seen as gender invariant. Lastly, according to the detailed information provided by IRT and the content of items, a reliable short form of the D28-C comprising 15 items was obtained. The study enriched the existing knowledge of the dark factor of personality in the Chinese background and made some revisions to the corresponding scale to make it a more reliable tool for measurement in China. In addition, the shortened version of the scale based on item information and content helps to improve the efficiency of the measurement.

Dark Tetrad, Acceptance of Sexual Violence, and Sexism

Abstract. The Dark Tetrad is a cluster of four “dark” personality traits which are socially aversive, with distinct conceptual roots, but which are intercorrelated: narcissism, psychopathy, Machiavellianism, and sadism. Narcissism is associated with inflated self-esteem and feelings of grandiosity; psychopathy involves reduced empathy and a lack of remorse or guilt; Machiavellianism is characterized by a tendency for manipulation for own personal benefit; sadism involves feelings of pleasure with the pain or suffering of others. Sexism is the group of beliefs linked with the perceived superiority of men over women. Previous studies have found relationships between the Dark Tetrad and the tolerance of the use of sexual violence and between the former and sexism. Furthermore, sexism has been linked with the acceptance of sexual violence. This study aims to revise the literature exploring the link between each of the components of the Dark Tetrad and the legitimation of the use of sexual violence; it also aims to present the associations that have been found between the aforementioned variables and sexism and related concepts, in multiple studies. Based on the previous literature, suggestions for aims of future research in this field (i.e., Dark Tetrad, sexual violence, sexism) are made, more specifically exploring the relative effect of each of the components of the Dark Tetrad in the explanation of the legitimation of sexual violence, as well as exploring a possible, at least partial, mediation of sexism in the link between each of the “dark” traits and the acceptance of sexual violence.

The bright and dark sides of the Dark Triad traits among senior managers: effects on organizational commitment

Senior managers play a fundamental role in organizations. They shape organizational strategy and culture, set the mission, including opportunities for new markets, and construct the business models. Their commitment to the organization is vital to organizational performance, yet research on personality traits of senior managers and their commitment to organizations is limited. Drawing on self-affirmation theory, we investigate the consequences of senior managers’ ‘Dark Triad Traits’ (narcissism, psychopathy, and Machiavellianism) for their organizational commitment. We use the three-component model developed by Allen and Meyer (J Occup Psychol 63:1–18, 1990) to distinguish affective, continuance, and normative commitment. Our findings from a dataset of 394 senior French managers collected between 2017 and 2018 show that narcissism positively affects continuance commitment and normative commitment. This study contributes to a neglected stream of research investigating the relationship between Dark Triad traits and organizational commitment; contributes to ‘destigmatizing’ Dark Triad traits, often considered problematic for individuals; and adds to the minimal research currently on manager personality and organizational commitment.

Dark personalities and general masochistic tendencies: Their relationships to giving and receiving sexualized pain

Recent research has shown that a tendency to harm others goes hand in hand with a tendency to harm oneself. The present two studies further supported the notion that the joy of harming others and oneself has a common core by showing positive relationships between dark personality traits (particularly psychopathy) and sexual masochistic preferences and between general masochistic tendencies and sexual sadistic preferences. Despite the overlap between dark personality traits and general masochistic tendencies, they independently predicted the engagement in sexual sadomasochism. These relationships statistically held when controlling for the impact of basic personality (Study 1). Study 2 found that self-enhancement, openness to change, and low conservation values serve as motivators for a person's attraction to sexual sadomasochism and shed some light on the differences between sexual sadomasochism and the Dark Tetrad. Overall, people who score relatively high on dark personalities and masochism are particularly predisposed to engage in sexual sadomasochism, in both the dominant and the submissive roles.

Bad Is Stronger Than Good

Abstract. Organizational scholars increasingly realize the importance of a dark personality in the workplace. Although a great deal has been learned in terms of the utility of dark personality for the prediction of workplace outcomes, the field has yet to consolidate in terms of which models and measures best reflect the nature of dark personality traits. To facilitate this discussion, the present review examines and evaluates both established and emergent models and measures of dark personality. Further, to inform future research, it also summarizes evidence concerning methodological issues that have been shown to impact levels of dark traits or to moderate their relationships with work outcomes. Finally, the paper considers the implications of widespread practices in the field of dark personality and makes recommendations for future theorizing, research practices, and implementation.

Other-Oriented Perfectionism in Children and Adolescents: Development and Validation of the Other-Oriented Perfectionism Subscale-Junior Form (OOPjr)

Research on adults indicates other-oriented perfectionism (requiring perfection from others) is associated with various consequential outcomes independent of self-oriented perfectionism (requiring perfection of the self) and socially prescribed perfectionism (believing others require perfection of the self). However, historically, the most widely used and researched measure of trait perfectionism in children, the Child-Adolescent Perfectionism Scale (CAPS), has omitted other-oriented perfectionism. In the present study, we address this by reporting on the multisource development and validation of the first self-report measure of other-oriented perfectionism specifically intended for youths: the Other-Oriented Perfectionism Subscale-Junior Form (OOPjr). Children ( N = 107; Mage = 11.5, SD = 1.7) completed the OOPjr, CAPS, and measures of perfectionistic self-presentation, narcissism, social disconnection, depressive symptoms, and parental psychological control. Parents provided ratings of children’s self-oriented, socially prescribed, and other-oriented perfectionism. Psychometric analyses indicated the OOPjr is a homogenous and internally reliable scale that, when factor analyzed alongside the CAPS, displays measurement invariance across gender and replicates the three-factor solution found in adults. Furthermore, parent ratings of other-oriented perfectionism showed unique positive relationships with OOPjr scores, but not CAPS scores. Likewise, other-oriented perfectionism had independent positive relationships with narcissistic superiority and achievement-oriented parental psychological control, after controlling for self-oriented and socially prescribed perfectionism. Overall, our findings provide preliminary support for the use of the OOPjr as a measure of other-oriented perfectionism in youths.

Dark triads, tetrads, tents, and cores: Why navigate (research) the jungle of dark personality models without a compass (criterion)?

This comprehensive review summarizes and evaluates the present state of the Dark Triad research literature (or more broadly, the dark personality trait literature), and as such serves both a pedagogical purpose, by providing an introduction or primer on the dark personality literature and a scientific purpose by directing future research on key issues that still have not been sufficiently addressed. In this review, we discuss and critique current operational conceptualizations of what it means for a personality trait to be classified as 'dark'. Also discussed is the Dark Core, as well as quantitative issues such as limitations of commonly used statistical treatments, such as multivariate analyses, bifactor modeling, and composite measures, and proposed solutions to some of these issues. Based on a comprehensive and critical appraisal of the literature, future directions are suggested to drive the dark trait field towards a more organized, parsimonious, and productive future.

Dark or disturbed?: Predicting aggression from the Dark Tetrad and schizotypy

Research on the personality foundations of aggression typically implicates either (a) aspects of the so-called "Dark Tetrad" or (b) severe mental disturbance (psychosis). The appearance of psychotic symptoms in general populations is termed schizotypy. We conducted two studies to compare the effects of dark personalities and schizotypy on aggression. Study 1 used standard inventories to investigate the overlap of Dark Tetrad traits with schizotypy in a sample of 977 undergraduates. All tetrad traits except narcissism were positively associated with schizotypy, but only at moderate levels. Study 2 administered the same personality battery to 303 members of an online community sample: Aggression outcomes were measured with both self-reports and a behavioral measure-the Voodoo Doll Task. Regression analyses determined the unique contributions of the five personality variables. Two dark traits-psychopathy and sadism-were strong predictors of self-report aggression. Schizotypy added incrementally to the Dark Tetrad in predicting both self-report and behaviorally measured aggression.

Aversive Personality and COVID-19

Abstract. The Coronavirus Disease 2019 (COVID-19) has strongly affected individuals and societies worldwide. In this review and meta-analysis, we investigated how aversive personality traits – that is, relatively stable antisocial personality characteristics – related to how individuals perceived, evaluated, and responded to the COVID-19 pandemic. Across 34 studies with overall 26,780 participants, we found that people with higher scores in aversive personality traits were less likely to perceive guidelines and restrictions to curb the spread of the virus as protective ([Formula: see text] = −.11), to engage in health behaviors related to COVID-19 ([Formula: see text] = −.16), and to engage in non-health-related prosocial behavior related to COVID-19 ([Formula: see text] = −.14). We found no consistent relation between aversive personality and negative effect regarding the pandemic. The results thus indicate the importance of aversive personality traits in understanding individual differences with regard to COVID-19.

"Perfect Leader, Perfect Leadership?" Linking Leaders' Perfectionism to Monitoring, Transformational, and Servant Leadership Behavior

Despite the growing interest in perfectionism and its many facets, there is a lack of research on this phenomenon in the context of leadership. Attending to this deficit, the present study is the first to investigate the relationship between the three facets of perfectionism (self-oriented, socially prescribed, and other-oriented perfectionism) and three types of self-rated leadership behavior. In Study 1 (N = 182), leaders’ perfectionism and its association to their organizational, goal-oriented leadership behavior—self-rated as transactional (management by exception) and transformational leadership—is explored. In Study 2 (N = 185), the relationship of leaders’ perfectionism to their servant leadership as a people-centered leadership behavior is investigated. In line with the perfectionism social disconnection model (PSDM), we assume other-oriented and socially prescribed perfectionism to be positively related to management by exception (i.e., monitoring behavior) and negatively related to transformational and servant leadership, whereas the opposite pattern is primarily predicted for self-oriented perfectionism. Our findings in Study 1 reveal a negative relationship between leaders’ self-oriented perfectionism as well as positive relationships to their other-oriented and socially prescribed perfectionism in management by exception, while no substantial correlations with transformational leadership have emerged. In Study 2, a negative association between other-oriented perfectionism and the forgiveness dimension of servant leadership is revealed, indicating a possible barrier to building interpersonal relationships of acceptance and trust. Additionally, self-oriented perfectionism has been proven to be a rather favorable trait in servant leadership.

Age and gender differences in socially aversive (“dark”) personality traits

The strong overlap of personality traits discussed under the label of “dark personality” (e.g., psychopathy, spitefulness, moral disengagement) endorses a common framework for socially aversive traits over and beyond the dark triad. Despite the rapidly growing research on socially aversive traits, there is a lack of studies addressing age-associated differences in these traits. In the present study ( N = 12,501), we investigated the structure of the D Factor of Personality across age and gender using local structural equation modeling, thereby expressing the model parameters as a quasi-continuous, nonparametric function of age. Specifically, we evaluated loadings, reliabilities, factor (co-)variances, and means across 35 locally weighted age groups (from 20 to 54 years), separately for females and males. Results indicated that measurement models were highly stable, thereby supporting the conceptualization of the D factor independent of age and gender. Men exhibited uniformly higher latent means than females and all latent means decreased with increasing age. Overall, D and its themes were invariant across age and gender. Therefore, future studies can meaningfully pursue causes of mean differences across age and between genders.

Examining the Short Dark Tetrad (SD4) Across Models, Correlates, and Gender

To date, no studies have examined a range of structural models of the interpersonally aversive traits tapped by the Short Dark Tetrad (SD4; narcissism, Machiavellianism, psychopathy, sadism), in conjunction with their measurement invariance (males vs. females) and how the models each predict external correlates. Using a large sample of young adults (N = 3,975), four latent variable models were compared in terms of fit, measurement invariance, and prediction of intrapersonal and interpersonal functioning. The models tested were as follows: (Model A) confirmatory factor analytic, (Model B) bifactor, (Model C) exploratory structural equation model, and (Model D) a reduced-item confirmatory factor analytic that maximized item information. All models accounted for item covariance with good precision, although differed in incremental fit. Strong invariance held for all models, and each accounted similarly for the external correlates, highlighting differential predictive effects of the SD4 factors. The results provide support for four theoretically distinct but overlapping dark personality domains.

Disengaging from Evil: Longitudinal Associations Between the Dark Triad, Moral Disengagement, and Antisocial Behavior in Adolescence

Previous work has identified important correlational linkages between the dark triad of personality (Machiavellianism, psychopathy, and narcissism) and antisocial behavior in adolescence. However, little is known about the longitudinal associations between these personality characteristics and antisocial behavior, and the processes underlying these linkages. We hypothesized positive bidirectional associations between the dark triad and antisocial behavior, and that increases in moral disengagement would underlie these longitudinal associations. In the current study, we examined these hypotheses in 502 Dutch adolescents (51.8% boys, Mage = 13.57, SD = 1.07) across three annual waves. Path models showed that antisocial behavior was positively associated with relative increases in moral disengagement, a general dark personality factor, and Machiavellianism specifically, but not the other way around. These paths were only observed in boys and more pronounced during the first year of the study. Finally, antisocial behavior was partly indirectly associated to psychopathy across time via antisocial behavior and moral disengagement at a later time point. Together, these findings suggest that dark personality characteristics and moral disengagement development are more likely to be the result of changes in antisocial behavior than the other way around.

Screening for Dark Personalities

Abstract. Consensus is emerging that the constellation of dark personalities should include the sadistic personality. To build a four-factor measure, we modified and extended the Short Dark Triad (SD3) measure to include sadism. A series of three studies yielded the Short Dark Tetrad (SD4), a four subscale inventory with 7 items per construct. Study 1 ( N = 868) applied exploratory factor analysis (EFA) to a diverse 48-item pool using data collected on MTurk. A 4-factor solution revealed a separate sadism factor, as well as a shifted Dark Triad. Study 2 ( N = 999 students) applied EFA to a reduced 37-item set. Associations with adjustment and sex drive provided insight into unique personality dynamics of the four constructs. In Study 3 ( N = 660), a confirmatory factor analysis (CFA) of the final 28 items showed acceptable fit for a four-factor solution. Moreover, the resulting 7-item subscales each showed coherent links with the Big Five and adjustment. In sum, the four-factor structure replicated across student and community samples. Although they overlap to a moderate degree, the four subscales show distinctive correlates – even with a control for acquiescence. We also uncovered a novel link between sadism and sexuality, but no association with maladjustment.

Dispositional Greed Scale: evidências de sua estrutura interna e parâmetros dos itens

Resumo Este estudo objetivou conhecer as evidências da estrutura interna da Dispositional Greed Scale (DGS) e os parâmetros de seus itens. Contou-se com a participação de 338 pessoas com média de idade de 26,5 anos (DP = 8,18), que responderam a DGS e perguntas demográficas. Os resultados indicaram uma solução unifatorial da DGS (Ω = 0,75). Análises via Teoria de Resposta ao Item demonstraram que os itens da DGS discriminam adequadamente os participantes e exigem baixa a moderada quantidade de traço latente para serem endossados. Ademais, detectou-se funcionamento diferencial, quanto à variável sexo, em apenas um item da DGS que apresentou impacto reduzido nas curvas características do teste total. Conclui-se que a DGS reúne evidências que corroboram sua qualidade psicométrica, podendo ser utilizada em estudos futuros que objetivem mensurar a ganância no contexto brasileiro.
