The Unified Narcissism Scale: Moving towards an integrated measure of narcissism

Narcissism as a psychological construct has had a contentious past both in its conceptualization and measurement. There is an emerging consensus that narcissism consists of grandiose and vulnerable subtypes, which share a common core. In the present research (N = 1002), we constructed a new measure of unified narcissism that reflects these contemporary understandings using items from the most widely used measures of grandiose and vulnerable narcissism: the Narcissistic Personality Inventory (NPI; Raskin & Terry, 1988, https://doi.org/10.1037/0022-3514.54.5.890), and the Pathological Narcissism Inventory (PNI; Pincus et al., 2009, https://doi-org/10.1037/a0016530). We used classical test theory and item response theory approaches to devise a 29-item Unified Narcissism Scale. The scale showed good internal consistency, and convergent and discriminant validity, and showed evidence of measurement invariance between men and women. This research gave strong support for the structure, reliability, and validity of the unified measure, which offers a promising avenue for further enhancing our knowledge of narcissism.

Person-situation navigation mechanisms at work

Rather than focusing on their dynamic interplay, research in I/O psychology has mostly focused on either person-level variables as predictors of work behaviors or the impact of situational variables on employees’ behaviors. By studying person and situation variables independently or by treating the situation as fixed, previous studies have largely failed to capture the active role employees take in affecting and managing their work situations. This raises the question of how adequately current research that focuses on either the person or the situation captures the reality of work life. To address this issue, this paper aims to provide a starting point for the integration of person-situation interactions at work into an overarching process model (i.e., Person-Situation Navigation Mechanisms Framework; Rauthmann & Sherman, 2016), and illustrates how previous research on I/O constructs can be positioned within this framework.

Authoring esteem: Writing about vicarious and personal life story chapters boosts state self-esteem

Constructing personal life stories carries benefits for psychological adjustment. We examined whether writing about the life stories of parents (i.e., vicarious life stories) hold similar advantages. In Study 1, we adapted an established experimental paradigm to an online format. Participants wrote either about personal life story chapters or about famous persons (control condition) and completed pre- and post-measures of state self-esteem. We found the predicted interaction as self-esteem increased in the chapter but not in the control condition. In Studies 2 and 3, we added the critical condition of writing about vicarious chapters. Study 2 did not find the predicted interaction. Instead, all three conditions increased in self-esteem. Study 3, which used a new neutral control task (writing about historical events), showed that the two chapter conditions, but not the control condition, increased in self-esteem. This suggests that authoring life stories for both oneself and close others momentarily boosts self-esteem.

Geographic variation in personality is associated with fertility across the United States

Levels of fertility and the shape of the age-specific fertility schedule vary substantially across U.S. regions with some states having peak fertility relatively early and others relatively late. Structural institutions or economic factors partly explain these heterogeneous patterns, but regional differences in personality might also contribute to regional differences in fertility. Here, we evaluated whether variation in extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience measured at the U.S. state-level was associated with the level, timing, and context of fertility across states above and beyond sociodemographics, voting behavior, and religiosity. Generally, states with higher levels of agreeableness and conscientiousness had more traditional fertility patterns, and states with higher levels of neuroticism and openness had more nontraditional fertility patterns, even after controlling for established correlates of fertility (r ~ |.50|). Personality is an overlooked correlate that can be leveraged to understand the existence and persistence of fertility differentials.

What does your favourite colour say about your personality? Not much

The claim that favourite colours reveal individuals’ personalities is popular in the media yet lacks scientific support. We assessed this claim in two stages. First, we catalogued claims from six popular websites, and matched them to key Big Six/HEXACO trait terms, ultimately identifying 11 specific, systematic, testable predictions (e.g., higher Extraversion among those who prefer red, orange, yellow, pink, or turquoise). Next, we tested these predictions in terms of the Big Six personality trait scores and reports of favourite and least favourite colours from 323 French-speaking participants. For every prediction (e.g., red-extraversion), we compared trait scores between participants who chose or did not choose the predicted colour using Welch’s t-tests. We failed to confirm any of the 11 predictions. Further exploratory analyses (MANOVA) revealed no associations between colour preferences and personality trait. Favourite colours appear unrelated to personality, failing to support the practical utility of colour-based personality assessment.

Personality predictors of emergency department post-discharge outcomes

Personality traits are important predictors of health behaviors, healthcare utilization, and health outcomes. However, we know little about the role of personality traits for emergency department outcomes. The present study used data from 200 patients (effective Ns range from 84 to 191), who were being discharged from the emergency department at an urban hospital, to investigate whether the Big Five personality traits were associated with post-discharge outcomes (i.e., filling prescriptions, following up with primary care physician, making an unscheduled return to the emergency department). Using logistic regression, we found few associations among the broad Big Five domains and post-discharge outcomes. However, results showed statistically significant associations between specific Big Five items (e.g., “responsible”) and the three post-discharge outcomes. This study demonstrates the feasibility of assessing personality traits in an emergency medicine setting and highlights the utility of having information about patients’ personality tendencies for predicting post-discharge compliance.

The judgment of personality: An overview of current empirical research findings

This article presents an overview of the current state of knowledge in personality judgment research. We discuss accuracy and bias in personality judgments, including types of inter-rater agreement and elements of criteria used to determine levels of agreement and accuracy. We then address 1) the words and phrases that people use to describe one another and themselves, 2) research investigating judgments of targets by perceivers per trait, and 3) research investigating judgments of targets by perceivers on profiles or sets of traits. We also provide 4) an outlook regarding important research questions that remain unanswered in this field.

Testing the relationships between narcissism, risk attitude, and income with data from a representative German sample

Narcissism is related to income and risk-taking behavior, but previous studies have computed only pairwise associations and have used only domain-specific risk-taking measures. We jointly investigated narcissistic admiration and rivalry, income, and general risk attitude. Using a representative sample from the German population (N = 14,473), we contrasted a model with an indirect effect through risk attitude to income and a model with additive effects of narcissism and risk attitude. We found stronger effects of admiration on risk attitude and income than of rivalry and no evidence of the proposed indirect effect. Contrary to previous studies, we found that an individual's income was independent of their risk attitude. In exploratory analyses (Response Surface Analysis, level-and-difference-approach), we found that the relative strength of admiration compared with rivalry positively predicted risk attitude and income. Taken together, our findings are consistent with the hierarchical model of grandiose narcissism.

Predicting current voting intentions by Big Five personality domains, facets, and nuances – A random forest analysis approach in a German sample

To understand what was driving individual differences in voting intentions in a large German sample, we investigated the predictability of voting intentions from the Big Five personality domains, facets, and nuances, thereby tackling shortcomings of previous studies. Using random forest analyses in a dataset of N = 4,286 individuals (46.01% men), separate models were trained to predict intentions to 1) not vote versus to vote, 2) vote for a specific party, and 3) vote for a left- versus right-from-the-center party from either the Big Five personality domains, facets, or nuances (represented by individual items). Except for intentions to not vote versus to vote, balanced accuracies to predict voting intentions marginally exceeded those achieved by a baseline learner always predicting the majority class. Using nuances over facets and domains slightly increased balanced accuracies. Results indicate that additional variables should be considered to accurately predict voting intentions, at least in German samples.
