Book Part Big five personality traits: dating apps [Book Part](Springer International Publishing, 2023) Sevi, Barış; Bostancı, İlksenThe big five personality traits (Openness to experience, Conscientiousness, Extrovertedness, Agreeableness, and Neuroticism) are in relation with different attitudes, behaviors, and constructs, including dating apps. The big five has shown to be related to being a user of dating apps, dating app use motivations, and to different behaviors related to dating app use.Article Examining the Role of Dark and Light Triad Traits on Sociosexuality(Routledge Journals, Taylor & Francis Ltd, 2025) Urganci, Betul; Sevi, Baris; Dogruyol, Burak; Sakman, EzgiSociosexual orientation-the tendency toward casual sex, is associated with dispositional components of personality such as higher scores of Dark Triad traits (narcissism, Machiavellianism, and psychopathy). Yet, it remains unknown which specific Dark Triad traits and Light Triad traits (Kantianism, Humanism, and Faith in Humanity) predict sociosexuality and its dimensions while controlling for the others. In the current study, using an online community sample (N = 308), we examined the links between Dark Triad traits, Light Triad traits, overall sociosexuality, and sociosexuality dimensions (attitude, behavior, desire). Using hierarchical regression, we found that only psychopathy emerged as the predictor of behavior, desire, attitude dimensions, and sociosexuality total score. This effect held when controlling for age, sex, relationship status, the other two Dark personality traits, and the Light Triad. Results suggest that individuals high on psychopathy have a greater tendency toward uncommitted relationships.Book Part Sociosexuality: Infidelity(2023) Urganci, Betul; Sevi, BarışArticle Citation - WoS: 9Citation - Scopus: 9A Longitudinal Assessment of Variability in Covid-19 Vaccine Hesitancy and Psychosocial Correlates in a National United States Sample(Elsevier Sci Ltd, 2023) Shook, Natalie J.; Oosterhoff, Benjamin; Sevi, BarışRecent evidence suggests that COVID-19 vaccine hesitancy is not static. In order to develop effective vaccine uptake interventions, we need to understand the extent to which vaccine hesitancy fluctuates and identify factors associated with both between- and within-person differences in vaccine hesitancy. The goals of the current study were to assess the extent to which COVID-19 vaccine hesitancy varied at an individual level across time and to determine whether disgust sensitivity and germ aversion were associated with between- and within-person differences in COVID-19 vaccine hesitancy. A national sample of U.S. adults (N = 1025; 516 woman; M-age = 46.34 years, SDage = 16.56, range: 18 to 85 years; 72.6 % White) completed six weekly online surveys (March 20 - May 3, 2020). Between-person mean COVID-19 vaccine hesitancy rates were relatively stable across the six-week period (range: 38-42 %). However, there was considerable within-person variability in COVID-19 vaccine hesitancy. Approximately, 40 % of the sample changed their vaccine hesitancy at least once during the six weeks. There was a significant between-person effect for disgust sensitivity, such that greater disgust sensitivity was associated with a lower likelihood of COVID-19 vaccine hesitance. There was also a significant within-person effect for germ aversion. Participants who experienced greater germ aversion for a given week relative to their own six week average were less likely to be COVID-19 vaccine hesitant that week relative to their own six-week average. This study provides important information on rapidly changing individual variability in COVID-19 vaccine hesitancy on a weekly basis, which should be taken into consideration with any efforts to decrease vaccine hesitancy and increase vaccine uptake. Further, these findings identify-two psychological factors (disgust sensitivity and germ aversion) with malleable components that could be leveraged in developing vaccine uptake interventions.Book Part Sex differences: disgust response(Springer International Publishing, 2023) Sevi, BarışDisgust is an emotion that involves the typical experience of a feeling of revulsion and the motivation to retract from substances that elicit disgust. Sex differences are one of its extensive study topics. Several different arguments have been provided for why a sex difference in disgust is present.Article Sociosexuality Is Associated With Disease Avoidance Tendencies and Can Decrease During a Real-Life Disease Threat(Springer, 2024) Sevi, Baris; Shook, Natalie J.Engaging in uncommitted sexual relationships increases the risk of pathogen transmission through close contact with novel partners. As such, greater disease avoidance tendencies may be associated with lower sociosexuality. Across three studies, we examined this proposition. In Studies 1a and 1b, we cross-sectionally assessed the associations between individual differences in disease avoidance (i.e., germ aversion, perceived infectability) and sociosexuality dimensions (i.e., behavior, attitude, desire). Greater germ aversion was significantly associated with more restricted sociosexuality across all three dimensions and replicated in both samples. Perceived infectibility was associated with more unrestricted sociosexual attitude and desire, but only in Study 1a. In Study 2, we tested whether sociosexuality levels changed with the COVID-19 pandemic. Participants reported more restricted sociosexuality levels during the COVID-19 pandemic compared to pre-pandemic levels, where a decrease was especially seen in sociosexual desire. Further, this decrease in sociosexual desire was predicted by pre-pandemic germ aversion levels. Overall, the findings indicate that disease avoidance tendencies (i.e., germ aversion) and real-life disease threat are associated with lower tendency to engage in uncommitted sexual relationships. Further research is needed to understand the causal relation of these two constructs, which may help in developing interventions and campaigns to support better sexual health.Article Big-5 Personality Traits as Predictors of Allostatic Load in Latino Americans: A Longitudinal Study(Oxford Univ Press Inc, 2025) Sevi, Baris; Supiyev, Adil; Gutierrez, Angela; Graham, Eileen K.; Mroczek, Daniel K.; Muniz-Terrera, GracielaObjectives Allostatic load (AL) refers to the measure of cumulative wear and tear resulting from chronic stress and life events. AL presents adverse consequences for a diverse range of health conditions, and Latino populations show a high risk for elevated AL. This study aimed to test the Big-5 personality traits as possible predictors of AL in Latinos.Methods Using data from the Health and Retirement Study, we examined the Big-5 and AL connection through three time points in 8 years (Time 1 = 2006/2008; Time 2 = 2010/2012; Time 3 = 2014/2016). Only self-identified Latinos were included in the analysis sample (N = 319). Big-5 and demographics were obtained at baseline, and AL scores were computed for each time point.Results First, separate longitudinal linear mixed-effect models examined the effects of each Big-5 personality trait on AL change over time, then a fully adjusted longitudinal linear mixed-effect model was tested entering the Big-5 personality traits simultaneously. All models controlled for sociodemographic factors. Conscientiousness emerged as the only consistent significant predictor, for the separate and the simultaneous models. In baseline associations, higher conscientiousness was associated with lower AL. For predicting change in AL over time, none of the personality traits had significant associations in any of the models.Discussion The findings bolster prior evidence that conscientious can be a protective factor against elevated AL. Conscientiousness is a possible protective factor and improving related traits can be a path to achieve better health in Latino Americans.Article Citation - WoS: 1Citation - Scopus: 1I See Sick People: Beliefs About Sensory Detection of Infectious Disease Are Largely Consistent Across Cultures(Academic Press Inc., 2025) Ackerman, Joshua M.; Samore, Theodore; Fessler, Daniel M. T.; Kupfer, Tom R.; Choi, Soyeon; Merrell, Wilson N.; Zezelj, IrisIdentifying cues to contagious disease is critical for effectively tracking and defending against interpersonal infection threats. People hold lay beliefs about the types of sensory information most relevant for identifying whether others are sick with transmissible illnesses. Are these beliefs universal, or do they vary along cultural and ecological dimensions? Participants in 58 countries (N = 19,217) judged how effective, and how likely they were to use, cues involving each of the five major sensory modalities in an imagined social interaction during a flu outbreak. Belief patterns were strongly consistent across countries (sight > audition > touch > smell > taste), suggesting a largely universal conceptualization of the role of sensory information for interpersonal respiratory disease detection. Results also support a safe senses hypothesis, with perceivers reporting that they would use senses that function at a distance-and thus reduce pathogen transmission risk-more than would be expected given participants' beliefs as to the efficacy of these senses for disease detection. Where societal variation did emerge, it was captured by a cohesive set of socio-ecological factors, including human development, latitude, pathogen prevalence, and population density. Together, these findings reveal a shared lens through which contagious respiratory disease is assessed, one that prioritizes minimizing risk to perceivers, and may offer leverage for designing interventions to improve public health.Article Underlining Neighbourhood Perception: a Possible Risk Factor for Dementia That Deserves More Attention(Oxford Univ Press, 2024) Gutierrez, Angela; Sevi, Barış; Muniz-Terrera, GracielaThis essay highlights the interplay between the neighbourhood structural environment and neighbourhood perceptions on dementia by articulating how an individual's perception of neighbourhood, with respect to their individual differences, may provide key insights to understand the link between the neighbourhood and dementia.Article Interplay of Neighborhood and Psychosocial Factors in Predicting Trajectories of Allostatic Load Among Latinx Adults in the United States(SAGE Publications Inc., 2025) Gutiérrez, Á.; Supiyev, A.; Thomas Tobin, C.; Sevi, B.; Marroig, A.; Voll, S.; Muniz-Terrera, G.Research highlights the independent roles of neighborhood and psychosocial risk and protective factors for accelerated physiological aging. However, the combined role of neighborhood and psychosocial factors for allostatic load among Latinx adults in the U.S. remains unclear. Informed by the Health Disparities Framework, the study aims are to: (1) examine the direct associations between neighborhood (cohesion and disorder) and psychosocial (loneliness) factors, respectively, and allostatic load trajectories; and (2) determine whether family social support moderates the association between loneliness and allostatic load trajectories. Data for Latinx adults ages ≥50 (n = 319) are from the Health and Retirement Study (waves 2006–2016). Linear mixed models estimated baseline and rate of change in allostatic load, adjusting for sociodemographics. Loneliness was positively associated with baseline allostatic load. This association persisted when we considered neighborhood factors. Family social support moderated the association between loneliness and allostatic load slope. As neighborhood features, loneliness, and physiological dysregulation are each associated with worse cognitive outcomes, findings underscore the protective role of family social support for physiological dysregulation, thereby promoting cognitive resilience. © The Author(s) 2025.
