Studies into paranormal belief and the effects thereof have been gaining more attention. This study looked at the Big Five Personality Traits and how they could relate to belief in the paranormal, specifically which personality traits, if any, lended themselves to paranormal belief more than others. Four hundred forty-six college-age participants completed a Big Five survey as well as the Revised Paranormal Belief Scale. Results from a multiple regression showed a significant relationship between gender, religion, level of education achieved by the participant's mother, extraversion, and neuroticism (emotional stability) in relation to paranormal belief. Implications and elaboration of findings are discussed.

Sugar intake continues to be connected to an increased risk of heart diseases, diabetes, arthritis, and certain forms of cancers, depression, and schizophrenia. The purpose of the study was to examine if sugar intake is related to personality traits in the Millennial population. The health belief model was used as the theoretical framework for conducting the study. The research questions addressed in the current study were in regards to the relationships between Millennials daily sugar intake and openness, conscientiousness, extraversion, agreeableness, and neuroticism. This study was a cross-sectional design in which a panel of randomly selected United States Millennials (N = 106) between the ages of 18-34 were requested to complete a demographic questionnaire and the Big Five Inventory. The survey was conducted online using SurveyMonkey. Multiple linear regression was used to test the five stated hypotheses. Study results indicated no significant relationship between sugar intake and the five personality traits (p > .05). A sequential multiple regression model after controlling for age and gender indicated no significant relationship between the five personality traits and Sugar Intake (p > .05). In effecting positive social change, further investigations are warranted to establish the relationships between personality traits and sugar intake which may help to inform policy to reduce the associated health risks of consuming high sugar.

The purpose of this study was to investigate the relationship between mentor characteristics (i.e., motivational tendencies, personality traits), mentoring provided, and protégé outcomes. A motivational approach was taken, in the sense that motives to mentor, as well as personality characteristics of the mentor, were considered in regard to their ability to predict the type of mentoring provided and outcomes for the protégé. Specifically, the potential relationships between personality traits (Intrinsic Motivation, Learning Goal Orientation, Conscientiousness, Extraversion, Agreeableness, and Machiavellianism) and mentor motives, as well as the provision of career and psychosocial mentoring, were examined. In addition, the current study examined the ability of mentor characteristics to predict several protégé outcomes. Ninety-one mentors (i.e., college juniors and seniors) were paired with 91 protégé (i.e., college freshmen) and were asked to meet for a half hour each week for four consecutive weeks. Self-report measures were collected from both mentors and protégés before the mentoring sessions began (T1) and after (T2) they were completed to determine the effect of having a mentor on various outcomes. All mentoring sessions were videotaped so that trained raters could code the type of mentoring behaviors that occurred within a given session. Results were analyzed via correlational analyses, exploratory regression analyses, and hierarchical regression analyses. Individuals who were generally more intrinsically motivated and learning goal oriented reported being more motivated to mentor others for intrinsic satisfaction reasons. Mentors who were more extraverted and agreeable than their peers reported being more motivated to mentor in order to benefit others. In addition, having a mentor who provided career mentoring reduced school-related stress for a protégé. The key findings of the current study provide support for the view that personality and motivational characteristics of the mentor affect the type of mentoring provided, albeit indirectly in some cases. In addition, it is important to consider multiple sources of mentoring data provided (i.e., mentor, protégé,independent rater) rather than just the protégé's point of view because this will provide a more well-rounded picture of the mentoring relationship, as well as identify potential gaps in perception that may exist between mentors and protégés.

The present study investigated the role of anxiety and avoidance dimensions of attachment and big five personality traits in adaptive and maladaptive dimensions of perfectionism. A pilot study was carried out with 408 (260 males and 148 females) preparatory school students of Middle East Technical University (METU) for the adaptation studies of Almost Perfect Scale-Revised (APS-R). The results of the exploratory and confirmatory factor analyses yielded a 21 item scale with three factors / Standards, Discrepancy and Order. The results of convergent and divergent and criterion-related validity studies revealed evidence for the adaptive and maladaptive dimensions of perfectionism. As for the main purpose of the study, three questionnaires, namely APS-R, Relationship Scales Questionnaire and Big Five Inventory were administered to 604 (377 males and 227 females) preparatory school students of METU. The results of three multiple regression analysis revealed that adaptive perfectionism as measured by Standards scores was significantly predicted by Conscientiousness, Openness and Extraversion. Maladaptive perfectionism as measured by Discrepancy scores was predicted by Neuroticism, Anxiety and Avoidance dimensions of attachment. Order scores used as an additional analysis were found to be predicted by Conscientiousness, Neuroticism, Extraversion and Openness.

The Covid-19 pandemic caused countries across the world to implement a wide range of restrictions and recommendations to control the spread of the virus. The current study aimed to investigate how differences in personality traits and differences in how an individual perceives the situation of Covid-19 among Swedish university students affect the overall compliance with guidelines applied by their government. A total of 106 university students completed a questionnaire measuring personality traits (Big Five) and perceptions of the situation (Situational Eight DIAMONDS) in relation to their self-estimated compliance. The data analysis showed that the students complied with the guidelines with a mean of 77%. Individuals who were less agreeable and perceived less adversity in the Covid-19 situation complied more. All predictor variables could account for approximately 28% of the explained variance in compliance. These results are of importance in a preparatory purpose for governments to efficiently cope with future threats.

Kärleksrelationer är en betydande del av många människors liv. En viktig del för en välfungerande relation är att visa varandra kärlek, förslagsvis genom olika kärleksspråk. De fem kärleksspråken utformades av Chapman (1992) och innefattar tjänster, fysisk beröring, bekräftande ord, kvalitetstid och gåvor. Kärleksspråk har visat sig vara en bidragande faktor för kvalitativa kärleksrelationer. Personlighetsdraget vänligheten från femfaktormodellen är bland annat kopplat till kärleksfulla och empatiska karaktärsdrag. Denna studie har som syfte att studera sambandet mellan vänlighet och kärleksspråk. Studien undersökte även om det fanns någon skillnad på vilket kärleksspråk man har beroende på om man är singel eller i en relation. Detta undersöktes genom en enkätstudie med 417 deltagare som skapades utifrån de validerade mätverktygen Dimensioner för kärleksspråk (Love Language Subscales) och Mini-IPIP (Mini International Personality Item Pool-Five-Factor Model). Data analyserades med hjälp av en korrelationsanalys samt ett t-test. Resultatet från korrelationsanalysen visade ett signifikant positivt samband mellan vänlighet och alla fem kärleksspråk. Med andra ord tyder detta på att personer som skattar högt på vänlighet även skattar högt på Chapmans fem kärleksspråk. T-testet visade endast en svagt signifikant skillnad mellan olika relationsstatus och fysisk beröring samt bekräftande ord, där de i relation skattade högre på båda. Relationsstatus tycks alltså kunna indikera personers kärleksspråk till viss del. / Romantic relationships are a significant part of many people's lives. An important part of a well-functioning relationship is showing love to each other, preferably through different love languages. The five love languages were developed by Chapman (1992) and include Acts of Services, Physical Touch, Words of Affirmation, Quality Time and Gifts. Love languageshave been shown to be a contributing factor to high quality romantic relationships. The personality trait Agreeableness from the Five-factor model is linked to loving and empathic traits, among others. This study aims to study the relationship between Agreeableness and love language. The study also investigated if there was any difference in love language depending on whether you are single or in a relationship. This was done through a survey study with 417 participants that was created using the validated measurement tools Love Language Subscales and Mini-IPIP (Mini International Personality Item Pool-Five-Factor Model). The data were analyzed using a correlation analysis and a t-test. The results of the correlation analysis showed a significant positive correlation between Agreeableness and all five love languages. In other words, this indicates that people who score high on Agreeableness also score high on Chapman's five love languages. The t-test showed only a weak significant difference between relationship status and Physical Touch and Words of Affirmation, with those in relationships scoring higher on both. Thus, relationship status seems to be able to indicate love language to some extent.

<p>Fundamental changes have been happening in healthcare organizations and delivery in these decades, including more accessible physician information, the low-cost collection and sharing of clinical records, and decision support systems, among others. Emerging information systems and technologies play a signification role in these transformations. To extend the understanding and the implications of information systems on healthcare, my dissertation investigates the influence of information systems on enhancing healthcare operations. The findings reveal the practical value of digitalization in indicating healthcare providers' cognitive behaviors, responding to healthcare crises, and improving medical performance.</p> <p><br></p> <p>The first essay investigates the unrevealed value of a special type of user-generated content in healthcare operations. In today's social media world, individuals are willing to express themselves on various online platforms. This user-generated content posted online help readers get easy assess to individuals' features, including but not limited to personality traits. To study the impact of physicians' personality traits on medicine behaviours and performance, we take a view from the perspective of user generated content posted by their supplier side as well as using physician statements which have been made available in medical review websites. It has been found that a higher openness score leads to lower mortality rates, reduced lab test costs, shorter time usage in hospitals treated by physicians with greater openness scores. Furthermore, taking these personality traits into consideration in an optimization problem of ED scheduling, the estimation of counterfactual analysis shows an average of 11.4%, 18.4%, and 17.8% reduction in in-hospital mortality rates, lab test expenditures, and lengths of stay, respectively. In future operation of healthcare, physicians' personalities should be taken into account when healthcare resources are insufficient in times of healthcare pandemics like COVID-19, as our study indicates that health service providers personality is an actual influence on clinical quality.</p> <p><br></p> <p>In the second essay, we focus on the influences of the most severe healthcare pandemic in these decades, COVID-19, on digital goods consumption and examine whether digital goods consumption is resilient to an individual’s physical restriction induced by the pandemic. Leveraging the enforced quarantine policy during the COVID-19 pandemic as a quasi-experiment, we identify the influence of a specific factor, quarantine policy, on mobile app consumption in every Apple app store category in the short and long terms. In the perspective of better responding in the post-pandemic era, the quantitative findings provide managerial implications to the app industry as well as the stock market for accurately understanding the long-term impact of a significant intervention, quarantine, in the pandemic. Moreover, by using the conditional exogenous quarantine policy to instrument app users’ daily movement patterns, we are able to further investigate the digital resilience of physical mobility in different app categories and quantify the impact of an individual’s physical mobility on human behavior in app usage. For results, we find that the reduction in 10% of one’s physical mobility (measured in the radius of gyration) leads to a 2.68% increase in general app usage and a 5.44% rise in app usage time dispersion, suggesting practitioners should consider users’ physical mobility in future mobile app design, pricing, and marketing.</p> <p><br></p> <p>In the third essay, we investigate the role of an emerging AI-based clinical treatment method, robot-assisted surgery (RAS), in transforming the healthcare delivery. As an advanced technique to help diminish the human physical and intellectual limitations in surgeries, RAS is expected to but has not been empirically proven to improve clinical performance. In this work, we first investigate the effect of RAS on clinical outcomes, controlling physicians' self-selection behavior in choosing whether or not to use RAS treatment methods. In particular, we focus on the accessibility of RAS and explore how physician and patient heterogeneity affect the adoption of the RAS method, including learning RAS and using RAS. Investigating the decision-making process on RAS implementation in both the learning and using stages, we show the synergy of RAS implementation in alleviating healthcare racial disparity. Ultimately, the mechanism analysis will be conducted to reveal the underlying mechanism that induces the enhancement of surgical outcomes. For instance, the estimations tend to reveal that, more than surging clinical performance, RAS tends to increase standardization in time and steps when applying the treatment procedures. </p>

L’objectif de ce mémoire est d’examiner les nombreuses associations qui existent entre les conditions de l’organisation du travail, les traits de personnalité et la détresse psychologique au travail. La question de recherche principale était : est-ce que les cinq grands traits de personnalité (Big Five personality traits) ont un effet modérateur sur la relation entre les conditions de l’organisation du travail et la détresse psychologique. De nombreuses autres questions ont aussi été considérées. Pour répondre aux vingt-et-une hypothèses proposées dans cette recherche, nous avons utilisé des données secondaires d’une étude transversale de 395 employés d’un service de police municipal. À la suite d’analyses multivariées, nous avons pu observer quatre associations significatives. Concernant les conditions de l’organisation du travail, nous avons trouvé que les demandes psychologiques en milieu de travail augment la détresse psychologique, tandis que le support d’un superviseur la diminue. En ce qui concerne, les traits de personnalité, nous avons trouvé qu’être névrotique (neuroticism) augmente la détresse psychologique. Finalement, nous avons trouvé un effet modérateur du trait de personnalité, être consciencieux (conscientiousness), sur la relation entre les demandes psychologiques et la détresse psychologique. Bref, nos résultats nous indiquent que les cinq grands traits de personnalité (Big Five personality traits) ont une influence mitigée sur la santé mentale en milieu de travail. / The current thesis sought to observe the multiple relationships that exist between work organization conditions, personality characteristics and psychological distress in the workplace. The main question of interest was whether the Big Five personality traits have a moderating effect on the relationship between work organization and psychological distress, but numerous other questions of interest were also considered. In order to address the twenty-one hypotheses proposed in this study, secondary data was used from a cross-sectional survey of 395 workers from a municipal police service. Multivariate analyses showed four significant relationships between the three variables of interest. With regards to the work organization conditions, it was found that psychological demands in the workplace increase psychological distress, whereas, support from a supervisor decreases psychological distress. With regards to personality, neuroticism was found to increase psychological distress. Finally, a moderating relationship was found for the conscientiousness trait on the relationship between psychological demands and psychological distress. Globally, the results indicate that the Big Five personality traits have a mitigated impact on mental health problems in the workplace.

Effective leadership, ethical leadership, and leadership emergence have been extensively researched, but there remains a lack of research on the relationship between the big 5 personality traits and authentic leadership. This quantitative study was based on the empirical principles of the big 5 model and guided by the big 5 theory. In addition, this research asked if there was a relationship between the big 5 model and authentic leadership, and which combination of the 5 personality traits best predict authentic leadership. Fifty-five adult participants, employed in various corporations, were recruited from a convenience sample. They rated their leaders by completing an Authentic Leadership Questionnaire, the NEO Five-Factor Inventory-3, and a demographic questionnaire. Data were analyzed using multiple linear regression analyses and the results showed that the big 5 personality model explained 46.9% of the variance (F (5, 49) = 8.65, p < .001. Conscientiousness positively (β = 0.40, p = .003) correlated with authentic leadership while neuroticism was inversely (β = -0.04, p = .046) correlated. These 2 traits best predicted authentic leadership and provided the strongest correlation. Extraversion (β = -.04, p = .739) and openness-to-experience (β = .25, p = .080) were non-significant traits. In the Pearson Correlation analysis, agreeableness had a weak inverse correlation with authentic leadership, (r (53) = -0.30, p = .027), and contributed 8.9% of the variance in predicting authentic leadership. Conscientious leaders with low level of neuroticism, who practice authentic leadership, will bring about positive social change by reducing unethical practices, improving communication with employers, employees, and consumers, and improving employee morale.
