Construct-irrelevant variance (CIV), defined as excessive variance that is unrelated to the intended construct, poses a significant threat to the validity of test interpretations and applications. CIV can arise from two notable sources: construct-irrelevant items, which include items with content unrelated to the construct being measured, and redundant items, which repeat information already captured by other items, leading to individual fatigue and inflated reliability estimates. This study explores the detection of CIV using network psychometrics in comparison with traditional psychometrics methods. The study utilizes the HEXACO-PI dataset, focusing on six personality dimensions, and applies network psychometrics techniques such as Exploratory Graph Analysis and Unique Variable Analysis. These techniques are compared against traditional methods, such as reliability and factor analysis, to assess their effectiveness in identifying CIV items. Results highlight the potential of network psychometrics as a complementary approach for enhancing the structural integrity of psychological instruments, with 89% agreement in the number of identified CIV items. This comparison provides insights into alternative methods for improving psychological instruments, with implications for the future of psychometric evaluation. Full article

Addressing climate change requires deeper insight into the psychological drivers of pro-environmental behavior. This study investigates how personality traits, climate-related emotions, and demographic factors can predict sustainable consumption and climate action participation using a Bayesian regression approach. Drawing from the HEXACO personality model and key emotional predictors—Climate Change Worry (CCW) and environmental empathy (EE)—we analyzed data from 604 adults in Greece to assess both private and public climate-related behaviors. This research is novel in its integrative approach, combining dispositional traits and affective states within a Bayesian analytical framework to simultaneously predict both sustainable consumption and climate action. Bayesian model testing highlighted education as the most powerful and reliable predictor of sustainable consumption, with increasing levels—namely Doctoral education—linked to more environmentally responsible action. CCW produced small but reliable effects, supporting hypotheses that moderate emotional concern will lead to sustainable behavior when linked to efficacy belief. The majority of HEXACO traits, e.g., Honesty–Humility and Conscientiousness, produced limited predictive power. This indicates in this case that structural and emotional considerations were stronger than dispositional personality traits. For climate action involvement, Bayesian logistic models found no considerable evidence of any predictor, corroborating the perspective that public participation in high effort action is most likely to rely on contextual enablers instead of internal sentiments or attributes. A significant interaction effect between education and gender also indicated that the sustainability effect of education is moderated by sociocultural identity. Methodologically, this research demonstrates the strengths of Bayesian analysis in sustainability science to make sensitive inference and model comparison possible. The results highlight the importance of affect-related structural variables in behavioral models and have applied implications for theory-informed and targeted climate education and communication interventions to enable different populations to act sustainably.

In this study, we examined the role of intellectual humility (IH) as an antecedent of individual attitude toward sustainable tourism viewed from the lens of personality trait theory, virtue ethics theory, and regenerative tourism principles within a stakeholder framework. Data were collected via Qualtrics in an online survey of 233 adults in the United States. A series of confirmatory factor analyses (CFA) were applied to the data to test the measurement model. In addition, a bifactor CFA was found to have acceptable fit and appropriate in controlling for common method variance. A series of covariance-based structural equations models (SEMs) was estimated to test the hypothesized model while controlling for common method variance in addition to individual age and gender. Using the chi-square difference test for nested model comparison, we found that intellectual humility was a significant antecedent of the negative ecological impact of tourism (β = 0.14, p < 0.01) while its relationships with economic and social impacts of travel became non-significant after controlling for common method variance. Pro-social tendency, operationalized as HEXACO Honesty–Humility, was also a significant antecedent of the negative ecological impact (β = 0.17) and positive economic impact (β = −0.34) of tourism, after controlling for common method variance. Despite its limitations due to its cross-sectional design and use of self-report data in the U.S., this study was novel in introducing intellectual humility as an important virtue to be cultivated at the individual level to achieve a holistic approach to sustainable tourism, especially in shaping destination choices. In addition, the study highlights the need to detect common method variance in self-report data via bifactor CFA to avoid erroneous reporting of significant findings, hampering our collective research efforts to address climate change and its impact.

With the HEXACO model of personality, this study examined the relationship between HEXACO traits (i.e., honesty–humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience) and teaching commitment among 2031 Chinese pre-service teachers. The results show that all HEXACO traits positively predicted teaching commitment, with extraversion and agreeableness being the most pronounced predictors. Also, this study investigated whether teaching motivation, including intrinsic motivation, altruistic motivation, and extrinsic motivation, could explain the relationship between HEXACO traits and teaching commitment. The results supported the mediational role of teaching motivation, with intrinsic motivation showing the strongest mediational effect. For extraversion and openness to experience, a full mediation model was supported, while for the other four HEXACO traits, a partial mediation model was validated. The theoretical and practical implications of this study for teacher education are discussed. Full article

This pilot study investigated how viewers perceive Monica Geller’s personality using three evidence-based personality models: Big Five, HEXACO, and Cloninger’s Biopsychosocial Model. Additionally, it examined how these perceptions are associated to audiences’ engagement in parasocial relationships with this iconic character from the sitcom Friends. A sample of sixty-three participants assessed Monica’s personality by responding to the Big Five Inventory (BFI), the HEXACO-60, and the Temperament and Character Inventory (TCI-60). Participants also completed the Multidimensional Measure of Parasocial Relationships (MMPR). Personality scores were contextualized against U.S. population norms (N_BFI = 711, N_HEXACO = 1126, N_TCI = 1948) and Pearson correlations were conducted to explore associations between personality traits and the Affective, Behavioral, Cognitive, and Decisional dimensions of parasocial engagement. Normative comparisons revealed Monica’s perceived Openness and Agreeableness in the Big Five and her Openness and Agreeableness in the HEXACO as significantly below average, while her Big Five Neuroticism and her HEXACO Conscientiousness were significantly above average. In the Biopsychosocial Model, Monica’s Persistence was significantly higher than population norms, while Cooperativeness was significantly lower. Big Five Agreeableness showed correlations across all parasocial engagement dimensions. HEXACO Emotionality was strongly linked to the Affective and Behavioral dimensions, while Honesty–Humility was associated with Cognitive parasocial engagement. In the Biopsychosocial Model, Reward Dependence and Cooperativeness were associated with Cognitive and Affective parasocial engagement, while Self-Directedness was linked to the Behavioral dimension. The Biopsychosocial Model offered the most comprehensive insights, capturing the multidimensional nature of viewer–character engagement. The Big Five and HEXACO models added valuable perspectives, particularly in explaining that traits associated with trust and kindness are linked to decision making. These findings emphasize the importance of integrating multiple personality frameworks to advance the understanding of parasocial relationship engagement, shedding light on the nuanced ways personality traits shape audience perceptions and relationships with media characters, with significant implications for media psychology and personality research. Limitations and avenues for future developments are discussed, building on the insights from this pilot study. Full article

Impulsive buying is a growing problem in modern society with significant financial and psychological consequences, and it is necessary to examine the mechanisms underlying it. Understanding the mechanisms driving this behavior is crucial. Impulsive buying consists of two key aspects: a cognitive aspect, characterized by a lack of planning and reflection, and an affective aspect, involving emotional responses that can occur before, during, or after a purchase. This study aims to explore the relationship between personality traits, as measured by the HEXACO model, and tendencies toward impulsive buying. Specifically, it examines how the HEXACO traits differentially predict the cognitive and affective components of impulsive buying tendencies. Data were collected from a sample of 420 students, with 32 excluded due to incomplete responses, resulting in a final sample of 388 students (155 men, 233 women) with an average age of 22.8. Hierarchical regression analyses revealed that HEXACO personality domains significantly predicted overall impulsive buying tendencies. As expected, Honesty–Humility and Conscientiousness were negatively associated with impulsive buying, while Emotionality and Extraversion positively predicted impulsive buying tendencies. Moreover, Honesty–Humility, Conscientiousness, and Extraversion significantly predicted the cognitive component of impulsive buying, while Honesty–Humility and Emotionality were significant predictors of the affective component. These findings suggest the importance of educating individuals, from an early age, on the negative consequences of impulsive buying, effective money-saving strategies, and the principles of mental accounting.

Climate change is an irreversible crisis that urgently calls for social transformation to protect human livelihood and environmental stability. Establishing awareness, building environmental literacy, and citizens’ mobilization are the steps toward sustainable change in giving a legacy of hope to future generations. This research explores major psychological and social drivers of pro-environmental behavior, considering the influence of HEXACO personality traits, climate anxiety (CCW), and social media engagement (SMI) on sustainable consumption (SC) and climate action intentions (CCI). Our findings revealed th eco-guilt (EGQ) and environmental empathy (EE) are immediate drivers for climate action, while long-term nurturance of eco-grief (ECOG) leads to engagement, supporting the notion that different emotions uniquely contribute to pro-environmental intentions. In terms of personality predictors, HEXACO’s traits of emotionality (E), honesty-humility (HH), and openness (O) are revealed to be significant, with emotionality also moderating the relationship between eco-grief and climate change action. The results reveal that connectedness to nature (CTN) and moderate levels of climate anxiety synergistically promote sustainable consumption intentions, while demographic factors such as gender, education levels, and exposure to social media moderate these intentions. Females also show a higher level of climate action intention in response to eco-guilt and eco-grief, while individuals with higher levels of education are more responsive to climate-related social media content, increasing their sustainable consumption behaviors. In exploring such interactions, this study aims to add to the understanding of what drives people toward valued environmental behaviors and, in turn, to inform effective climate advocacy, education, and personality-driven strategies to promote environmental engagement.

Human blood is one of the most valuable and irreplaceable goods in modern medicine. Although its necessity increases daily, one of the most significant challenges we have to overcome is a scarcity of willing blood donors. Volunteer motives and attitudes have been studied for decades, but it is now considered vital to grasp the many aspects that will increase the effectiveness of attracting new blood donors. This study focuses on the impact of emotional arousal produced by advertising messages, as well as the determining role of altruistic and egoistic incentives in deciding behavior. We also incorporated the element of personality to investigate how personality traits influence behavioral intention to donate blood. To this end, a quantitative non-experimental correlational 2 × 2 experimental design (positive vs. negative emotional appeal; altruistic vs. egoistic message) was implemented with the participation of 462 respondents who were shown a total of 12 advertisements (ads) promoting blood donation. The data were analyzed using structural equation modeling, with a focus on the direct impacts on donation intentions, the role of emotional arousals and attitude towards the ads as mediators and the moderating effect of the message. The empirical results of our hypotheses revealed that only Honesty–Humility had a strong direct impact on behavioral intention to donate, while Emotionality and Agreeableness did not have any direct effect. On the other hand, attitudes towards advertisements significantly and directly influenced positive and negative emotional arousals, respectively. Furthermore, if we consider these two variables alone, they can be found to exert a direct impact on BI. Mediation analysis showed that attitudes towards the advertisements and emotional arousals partially mediated the relation between Honesty-Humility and Behavioral Intention, thus confirming partial mediation. With respect to Emotionality and Agreeableness, mediation was found to be full since these factors only affected BI through a mediated path, which confirmed full mediation. Furthermore, the moderation analysis highlighted that the type of message (altruistic vs. egoistic) significantly moderated the relationship between both emotional arousals and BI. In particular, positive emotional arousal’s influence is strengthened when it is aligned with altruistic messages, while negative emotional arousal’s influence is weakened if it follows an altruistic message. These findings illustrate that using positive emotions will be more beneficial for increasing people’s donation intentions than bringing negative ones, which implies that message framing has a hidden impact on donation decisions.

During the COVID-19 pandemic, people exhibited various forms of adjustments. This study examines how situational factors (i.e., the severity of COVID-19) and individual differences (i.e., the HEXACO traits) affect one’s COVID-19-related responses regarding behaviors (i.e., mask-wearing and hoarding), worries (i.e., worrying about infecting and spreading COVID-19), and attitudes (i.e., discrimination and empathy toward people infecting COVID-19) in China. With a sample of 927 participants, our results show that the severity of COVID-19 was predictive of all the responses, and its predictive value was more pronounced relative to personality traits. Concerning the association between personality traits and responses, Honesty-Humility and Conscientiousness were predictive of one’s behaviors, Emotionality was predictive of one’s worries, and almost all the HEXACO traits were associated with one’s attitudes toward people infected with COVID-19. This study sheds some light on understanding how situations and individual differences shape one’s responses in a time of emergency. Full article

Trust and distrust are constructs that have provoked and undergone lots of discussion in the fields of sociology and psychology. However, to our knowledge, there is little agreement about how these constructs should be treated in the future. The present study tries to help in this discussion by re-analyzing prior neurophysiological data highlighting differences between trust and distrust by connecting these data with two distinct personality dimensions. Thus, the objective was to analyze the connection between neurophysiological trust/distrust processing and distinct HEXACO personality dimensions. Differences were found in the event-related potentials (ERPs) calculated for visual presentations of political institution words and brand names, which were evaluated with respect to trust and distrust by button presses. Two time points (330 ms and 780 ms) showed brain activity differences between trust and distrust related to the two word categories at frontal electrode locations. For this study, these findings were taken and connected to HEXACO-60 personality inventory results collected from prior participants. Statistical analysis revealed a significant interaction between the ERPs and two HEXACO personality dimensions concerning trusted brands at the later time point (780 ms) at the right frontal electrode location F8. This result is taken as neurophysiological evidence that parameter values of the personality traits honesty–humility and agreeableness have an influence on brain functions related to trusted brands.

Given the serious humanitarian crises encountered by the modern world, it is more crucial than ever to build a society based on solidarity, compassion, empathy, and a sense of teamwork and cooperation. This research provides insight into how the factors of personality traits, altruistic behaviors, and humanitarian actions can positively influence citizens’ behavioral intentions, allowing for a deeper understanding of the motives behind charitable giving. To this end, a study was conducted with 332 Greek respondents, which used a special purpose questionnaire, including the HEXACO-24 questions and 13 additional questions, that addressed attitude towards advertisement, charitable giving, as well as the behavioral intention to donate. The findings add to current research by underlining the relevance of individuals’ altruistic character, since our analysis revealed a statistically significant relationship between charitable giving and behavioral intention to donate. All HEXACO personality traits, excluding emotionality, demonstrated a statistically significant positive relationship with the attitude towards advertising, while none of the personality traits exhibited a statistically significant positive relationship with the concept of charitable giving, which calls for further investigation. Our findings also revealed that attitude towards an advertisement had no drastic effect on charitable giving and behavioral intention. Full article

Nowadays, people have started to spend more and more time using the Internet, which has a crucial impact on people’s lives. Individual personality type is often the main factor dictating the various behaviors that people carry out, and it dominates their activities when socializing, communicating, and making choices in the virtual world. This study is dedicated to uncovering how the six dimensions of personality traits relate to players’ in-game behavior. This research is divided into two studies. Study 1 uses the K-means method to classify players in “Clash of Kings”, an online strategy video game, according to their activities. Using apriori algorithm, this research analyzes the correlation between in-game behavior and personality. In Study 2, the correlations are validated. In conclusion, not all personality traits are related to in-game behaviors. Players with high extraversion demonstrate more killings and attacks in games. Conscientiousness is negatively related to deaths. Emotionality shows strong extremes. The highest or lowest emotionality scores are associated with killings and attacks, while players with moderate emotionality will behave irregularly. Honesty/humility, agreeableness, and openness to experience are not predictive of in-game behaviors. For game manufacturers, players’ personality traits can be inferred through their corresponding in-game behaviors, to use in order to carry out targeted promotions. Full article

Adolescence is an important developmental period for both trust behavior and personality maturation, and individual differences in trust decisions may be related to different personality traits. In the current study, a group of adolescents (n = 483, M_age = 13.5, SD_age = 0.4) played two counterbalanced conditions of a multi-round trust game. In one condition, the partner displayed trustworthy behavior (the trustworthy condition), while the partner in the other condition played untrustworthy behavior (the untrustworthy condition). Three types of trust behavior were examined: initial trust behavior, the adaptation of trust behavior (trustworthy condition), and the adaptation of trust behavior (untrustworthy condition). Personality was measured using the Brief HEXACO Inventory. We expected the HEXACO personality dimensions of honesty–humility and agreeableness to be positively associated with initial trust behavior, but conscientiousness to be negatively related to initial trust behavior. The examination of the relationship between these dimensions and the adaptation of trust behavior were conducted on an exploratory basis. The investigation of the relationship between the remaining dimensions (emotionality, extraversion, and openness to experience) and the three types of trust behavior were also carried out on an exploratory basis. For each type of trust behavior, a hierarchical multiple regression analysis was undertaken to examine whether the HEXACO personality dimensions were related to trust behavior. Using frequentist analyses, no evidence was found that supported the HEXACO dimensions as significant predictors of the three types of trust behavior. Moreover, additional Bayesian analyses showed evidence that the hypothesized HEXACO dimensions (honesty–humility, agreeableness, and conscientiousness) did not outperform the non-hypothesized HEXACO dimensions (emotionality, extraversion, and openness to experience). The association between personality traits and trust might be less pronounced during adolescence as personality maturates across an individual’s lifespan. Additionally, due to a heightened sensitivity to the environment, contextual cues may affect adolescent decision-making processes, leaving less room for personality-driven behaviors. Full article

(1) Background: The aim of the study was to investigate if the Dark Triad (DT)—which includes psychopathy, Machiavellianism and narcissism—impulsiveness and Honesty-Humility (HH), can predict individuals’ intended behavior in a one-shot Prisoner’s Dilemma Game (PDG) and whether this relationship is moderated by gender. (2) Methods: A cross-sectional correlational design was used, examining regression and moderation models. A total sample of 197 working adults from Greece (64% women, M_age = 35.13 years old) completed a one-shot, simulated PDG, the Dirty Dozen scale, the Barratt Impulsiveness Scale and the Honesty-Humility subscale from the HEXACO NEO-PI. (3) Results: Significant correlations between overall DT score, narcissism and psychopathy scores and impulsiveness and all three DT traits, as well as the overall DT score and honesty-humility, were identified. Overall DT scores were found to increase the odds of defecting, while gender significantly moderated the effects of Machiavellianism, HH and impulsiveness on the participants’ behavior in the one shot PDG, leading to different effects for men and women. (4) Conclusions: Gender moderates the relationship between certain personality traits and behavior in social situations involving interdependence and/or moral decision making, such as the PDG, leading to changes both in terms of the statistical significance and the direction of the effect. Simulated social situations could serve as situational judgment tests in an effort to develop a better understanding of the underpinning mechanisms between personality, gender and social behavior.

Contrary to the common notion that personality and intelligence are unrelated constructs, numerous correlational studies have demonstrated substantial associations between the two domains. Moreover, samples of intellectually gifted individuals have been found to differ from the general population in specific aspects of their personalities. However, most studies so far have relied on the Five-Factor Model of Personality (FFM), while none have investigated this phenomenon using the HEXACO personality framework. We recruited 617 adult members of the international high-IQ society MENSA and compared them to 3 reference samples (combined N = 112,637) regarding their personalities as measured by the HEXACO-60 personality inventory. We found that gifted persons scored higher in Honesty-Humility and Conscientiousness but lower in Emotionality compared to reference samples. Interestingly, gifted individuals scored only slightly higher in Openness to Experience, and no consistent differences emerged for Agreeableness. We demonstrate that some known personality differences between gifted and non-gifted persons translate from the FFM to the HEXACO model, while others do not. Our results indicate that within the HEXACO factor structure differences in sociability are more pronounced, while intellect-related differences are comparatively weak. Full article
