The current thesis presents five studies which consider the structure of normal range human personality as measured by psychometric inventories. The primary aim of the thesis was to develop a hierarchical model of the structure of human personality, which not only encapsulated the content of extant personality inventories, but extended the extant models to better represent the accumulated knowledge in the field of personality research. To do so, the thesis reports on the largest item level exploratory and confirmatory factor analytic investigation of the structure of personality to date. In Study 1, the utility of confirmatory factor analysis (CFA) for the investigation of personality structure was established by conducting dimensionality, structural and invariance analysis of the 16 Personality Factor Questionnaire, Version 5, using the US Standardization sample. The results clearly demonstrated that confirmatory models of personality inventories can display model fit, and that structures can be identified which are invariant across samples. In Study 2, 1,772 items from the Eugene-Springfield community sample were used to locate 78 unidimensional narrow personality facets, which were both substantively consistent and displayed strong psychometric properties. These 78 facets were then used to identify a second order 11 factor global structure to human personality, the 11+ Model. The 11+ Model was robust over different rotational criteria, and displayed excellent theoretical coverage of the personality sphere. However, confirmatory factor analyses of the 11 factor solution failed to demonstrate model fit. As a result, three further studies were conducted to explore the possible reasons for model misfit. In Study 3, the model fit of the new exploratory 11 factor solution was considered against model fit for extant structures and inventories. The results showed that across modelling strategy, the fit of newly identified structure was comparable to the extant inventories. In Study 4, the claim the model misfit is caused by the inherent complexity in personality was considered through an application of exploratory structural equation modelling (ESEM). ESEM has been argued to more adequately represent such complexity. Results suggested that the ESEM framework fails to offer additional information to help resolve the substantive problems in personality research. Finally, in Study 5, the sample size required to reliably estimate single factor confirmatory models, and second order structural models, was investigated using Monte Carlo simulations. The results suggest that samples of over 2000 are required to reliably estimate second order structural parameters in confirmatory factor analytic models. This finding suggests the samples used in much published research to investigate confirmatory structural models of personality inventories may be deficient.

A distinction between ruminative and reflective forms of dispositional self-focus is introduced and the theoretical utility of this distinction is evaluated in a program of eight studies. Study 1 examined for the presence of this distinction among natural language trait descriptors. Study 2 evaluated whether this distinction provided a sufficient summary of relations between the Fenigstein, Scheier and Buss (1975) Self-Consciousness scales and the Five Factor Model of personality (FFM). In Study 3, two brief questionnaire measures of ruminative and reflective tendencies were developed, and their convergent and discriminant validity evaluated with respect to the FFM, and the Fenigstein et al. (1975) Public Self- Consciousness (PUSC) and Private Self-Consciousness (PRSC) scales. Study 4 investigated the extent to which rumination and reflection separately account for PRSC associations with measures of psychological distress (e.g., Beck Depression scale) and intellective dispositions (e.g., Need for Cognition scale), respectively. Study 5 evaluated, using a sample of dormitory roommates, the extent to which self-estimates of ruminativeness and reflectiveness correspond with the judgments of a knowledgeable observer. Studies 6, 7, and 8 evaluated the extent to which the traits of rumination and reflection separately account for previously reported PRSC associations with three theoretically relevant criteria of private self-consciousness: state indices of self-focused attention (Study 6), the asymmetry effect in self-other similarity judgments (Study 7), and research volunteerism (Study 8). Findings suggest that the PRSC scale confounds two relatively independent, and motivationally distinct dispositions, rumination and reflection, and that latent ruminative and reflective components of PRSC scores separately and fully account for PRSC correlates and effects. These findings provide a straight forward explanation of the "self-absorption" paradox implicit in the PRSC research literature, i.e., the consistent but apparently contradictory finding of more accurate and extensive self-knowledge, yet higher levels of subjective psychological distress, among persons high in private self-consciousness. It is likely that the PRSC's associations with psychological distress are uniquely due to its neurotic component (rumination), and that the PRSC's self-knowledge effects are uniquely due its intellective component (reflection). It is argued that rumination and reflection represent statistically and functionally independent self-focusing tendencies. Their strong and unique associations with the FFM dimensions of neuroticism and openness, respectively, imply a basic dichotomy of self-attentive motives: anxiety/fear and curiosity/exploration: rumination represents a useful summary conception of self-attentiveness motivated by perceived threats, losses, or injustices to the self; reflection represents a useful summary conception of self-attentiveness motivated by intrinsic curiosity, or epistemic interest in the self. It is concluded that the spatial metaphor of "direction" may not be an appropriate basis for a useful scientific conception of dispositional self-consciousness. The concept of a purely cognitive tendency to have attention chronically directed toward the self versus away from the self, construed independently of the emotional and motivational determinants of such a tendency, is probably untenable. / Arts, Faculty of / Psychology, Department of / Graduate

Organizational commitment has been linked to several important outcomes, including employee turnover and work performance. Despite that the antecedents of organizational commitment have been a subject of research for several decades, the relation between personality and organizational commitment is relatively unexplored. The aim of this study was to examine the relations between the personality traits in the five-factor model (Conscientiousness, Agreeableness, Neuroticism, Openness to Experience, and Extraversion) and organizational commitment. Personality was measured by the IPIP30 questionnaire. Three types of organizational commitment (affective commitment, continuance commitment, and normative commitment) were measured by the Organizational Commitment Questionnaire. The respondents (N = 303) consisted of workers from both the public and the private sector in Sweden. Multiple linear regression analyzes showed that Conscientiousness was statistically significantly related to affective commitment. Agreeableness, Neuroticism, and Extraversion were statistically significantly related to continuance commitment. Practical implications of the results as well as future research directions are discussed.

Forskning tyder på att faktorer som exempelvis personlighetsdrag, kön, ålder, relationsstatus och erfarenhet kan påverka en individs risktolerans. Det förekommer dock tvetydigheter om hur olika faktorer påverkar risktolerans. Denna studie undersökte vilka bakgrundsvariabler och personlighets­dimensioner som relaterade till risktolerans samt vilka variabler som var mest avgörande för att kunna förklara den totala variationen av risktolerans. Studien hade tre frågeställningar. I studien deltog 133 högskolestudenter. Deltagarna fick besvara en enkät bestående av Shafers personality scale som mäter de grundläggande personlighetsdimensionerna enligt femfaktorteorin samt 13-item instrument som mäter risktolerans. Studiens frågeställningar besvarades med Pearsons produktmomentkorrelationskoefficient och en stegvis multipel linjär regressionsanalys med forward selection. Korrelationerna visade att män, ekonomistudenter och privatsparande hade högre risktolerans än kvinnor, övriga ämnesområden och icke-privatsparade. Neuroticism korrelerade negativt med risktolerans. Samma variabler var mest avgörande och kunde förklara 28% av den totala variationen i risktolerans bland högskolestudenter. Det diskuterades att intresse och kunskap möjligen inverkade på risktolerans.

No / Purpose ¿ To examine the psychometric properties and construct validity of the general decision making style (GDMS) questionnaire in two UK samples. Design/methodology/approach ¿ The GDMS takes the form of a self-report questionnaire which identifies five decision making styles: rational, intuitive, dependent, avoidant, and spontaneous. It was administered to samples of business studies undergraduates in two UK business schools. Analyses included scale reliabilities, test-re-test reliability, and both exploratory and confirmatory factor analyses. Findings ¿ The instrument's internal and temporal consistencies were generally sound. Consistent with earlier studies, analyses undertaken on the two samples independently were generally supportive of a five factor model of decision making style. No relationships with gender or year of study were observed.

The relationship between personality trait change and major life events is currently undergoing extensive investigations within the field of personality psychology. A debate has risen regarding whether or not major life events can bring about trait change, and how typical trait change patterns over the adult lifespan can be explained. It is valuable to understand how traits change because they predict important future outcomes. The Five-Factor Theory described by McCrae and Costa (2008a) states that traits are purely biological entities, and trait change is explained to result from processes of intrinsic biological maturation, unaffected by life events. This thesis reviewed the literature regarding the relationship of trait change and life events, and the research of potential biological bases of traits in the brain together with a brain developmental perspective of intrinsic maturation. Gaining an insight in the relationship between personality traits and the brain is a goal within a young field of research called personality neuroscience, and an agenda of the Five-Factor Theory. Major life events do cause trait change, but the relationship is complex. A brain developmental perspective of intrinsic maturation did not entirely correspond with patterns of typical trait change in young adulthood. The Five-Factor Theory is challenged and modifications are suggested. Neurobiological correlates of five-factor traits reveal issues and potentials for future research.

Objectivity is often emphasized as one of the fundamental principles for the auditing profession and is also a requirement for preserving satisfactory professional practice. The multiple company scandals in the first decade of the 21st century have created distrust for auditors’ capability to maintain objectivity. The purpose of this study is to contribute with a new way of thinking when it comes to the factors that affect objectivity. Earlier studies have indicated that personality factors may affect work performance in many different fields and this study is exploring the connection between separate personality factors, and the capability of less experienced auditors to maintain objectivity in the relationship with dominating and demanding clients. Data was collected through a survey that was divided into two separate parts where the first part measured the participant’s score on different personality factors, and the other part measured the participant’s score on perceived objectivity. 133 subjects participated in the study and these subjects were divided into non-authorized or non-approved auditors and recently authorized or approved auditors. The result of the study did not indicate any significant connection between perceived objectivity and the different personality factors. However, there was a statistically significant connection between authorization and perceived objectivity. Non-authorized and non-approved auditors in the study tended to score higher on perceived objectivity than did their authorized counterparts. In order to regain the trust for auditors and to strengthen the role of the profession it is important to increase objectivity. The surprising evidence supplied by this study creates a curiosity and urge to further investigate the factors affecting objectivity, especially in combination with possible psychological aspects. This study is unique because it focuses strictly on individual instead of contextual factors and it thereby contributes to the literature about the influence of individual factors as well as to the study of objectivity among auditors. This is a step towards greater understanding of the factors that actually affect objectivity and, as a consequence, also affect the quality of the audit as a control mechanism. / Objektivitet framhålls ofta som en av de grundläggande principerna för revisorsyrket samt ett krav för att upprätthålla god yrkessed. Det tidiga 2000-talets stora företagsskandaler har dock skapat en misstro till revisorer som yrkesgrupp och har dessutom föranlett ett tvivel gentemot revisorers objektivitet. Avsikten med denna studie är att bidra med nya tankebanor kring vad som skulle kunna påverka objektiviteten. Tidigare studier har indikerat att personlighetsfaktorer kan påverka arbetsprestationen inom vitt skilda branscher och denna studie undersöker sambandet mellan olika personlighetsfaktorer och mindre erfarna revisorers förmåga att bibehålla objektiviteten i relationen med dominerande och krävande klienter. Data till studien samlades in genom en tvådelad enkät där en del mätte personligheten och den andra delen mätte graden av objektivitet. I studien deltog 133 respondenter fördelat på revisorsassistenter, revisorer som varken är auktoriserade eller godkända samt revisorer som har auktoriserats det senaste året. Resultatet av studien påvisar inte några signifikanta samband mellan graden av objektivitet och de studerade personlighetsfaktorerna. Istället påvisades ett signifikant samband mellan auktorisation och graden av objektivitet. Revisorer som varken var godkända eller auktoriserade visade i studien tendenser till högre grad av objektivitet än sina auktoriserade kollegor. I fråga om att vinna tillbaka förtroendet för revisorerna och att stärka deras yrkesroll är det viktigt att öka graden av objektivitet. Informationen som den här studien ger är överraskande och skapar framför allt en nyfikenhet och forskarlust att gräva djupare i objektivitetens påverkansfaktorer, och då i synnerhet i kombination med tänkbara psykologiska aspekter. Denna studie är unik då den i allra högsta grad fokuserar på individfaktorer istället för kontextuella faktorer och därmed bidrar till litteraturen om individfaktorers påverkan såväl som till studiet av objektivitet hos revisorer.  Detta är ett led i förståelsen av vilka faktorer som faktiskt har inverkan på objektivitet och därmed också har inverkan på kvaliteten hos revisionen som kontrollfunktion.

In the realm of asset pricing models, the Fama-French five-factor model has become a foundational framework for explaining the variation of excess stock returns. However, as financial markets continue to evolve, there arises a need to explore potential extensions to capture additional sources of risk and return. One such extension involves incorporating the difference between the actual and expected interest rates as an additional factor. This report delves into the empirical testing of this extended model and assesses its implications for explaining the variation of excess returns on the Swedish stock market. The rationale behind introducing such a factor is rooted in its potential to capture variations in excess returns attributed to unexpected changes in interest rates. To evaluate its efficacy, a comprehensive analysis was undertaken, focusing on three key aspects: the statistical significance of the factor, its impact on model fit, and its role in explaining variations in excess returns. Upon conducting time-series regressions across three sets of nine portfolios, it was found that while the factor exhibited notable coefficients with substantial influence on explaining excess returns, it failed to achieve statistical significance. This outcome prompts a crucial question: can an extension with a factor of high explanatory power but low significance truly enhances our understanding of stock returns? The findings suggest that despite its influence, other factors present in the model might already absorb the explanatory potential attributed to the new factor. Further examination of the extended model's performance provides insights into the overall model fit. The GRS statistic indicates that the extended model offers a superior fit compared to the original five-factor model. However, the adjusted R2 values suggest that this enhanced fit is not translated into a meaningful improvement in the model's ability to explain variations in returns. This prompts a nuanced consideration of whether the complexity introduced by the additional factor aligns with its incremental ability to explain variation in returns. / Inom asset pricing models har Fama-French five-factor model blivit ett av de mest grundläggande ramverken för att beskriva variationen i överavkastning. Eftersom finansmarknaderna fortsätter att kontinuerligt utvecklas finns det ett behov av att undersöka potentiella utvidgningar av modellen för att hitta ytterligare källor till risk och avkastning. Ett exempel av en sådan utveckling är att skillnaden mellan faktiska och förväntade räntor läggs till som en ytterligare faktor. I detta arbete utförs empiriska tester för att kunna bedöma om en utvidgad modell kan användas för att kunna beskriva variationen i överavkastning på den svenska aktiemarknaden. Motivation bakom att införa en sådan faktor är dess potentiella kraft i att beskriva variation i överavkastning hänförligt till oförväntade förändringar av räntor. För att utvärdera dess effektivitet utfördes en omfattande analys som fokuserade på tre nyckelaspekter: faktorns statistiska signifikans, dess påverkan på model fit och dess roll för att förklara variation i överavkastning. Efter att ha utfört tidsserieregressioner över tre uppsättningar av nio portföljer, visade det sig att medan faktorn uppvisade anmärkningsvärda koefficienter med betydande inflytande på att förklara variationen i avkastning, var den emellertid ej statistiskt signifikant. Detta utfall ger upphov till en viktig fråga: kan en utvidgad modell med en faktor med stor förmåga att förklara, men med låg signifikans, förbättra vår förståelse av variation i överkastning? Resultaten antyder att trots den nya faktorns förklarande förmåga, har den förklarande förmåga som tillskrivits den nya faktorn redan absorberats av tidigare faktorer i modellen. Vidare undersökning av den utvidgade modellens prestanda ger insikter i hur modellen är anpassad till observationer. GRS-statistiken visar att den utvidgade modellen är bättre anpassad än den ursprungliga modellen. Dock visar adjusted R2 värdena att detta inte översätts till en meningsfull förmåga att beskriva variationen i överavkastning. Detta ger upphov till en diskussion om huruvida den ökade komplexitet som införs är i linje med dess inkrementella värde i att förklara variation i överavkastning.

Research has suggested that the Five Factor Model (FFM) is useful in describing personality pathology as well as personality traits. However, there appears to be disproportionate implications of the five domains for problems in living. Previous empirical research concerning the differential direction and magnitude of the relationship of the FFM domains to problems in living and personality disorder symptomatology has perhaps been limited in part by the use of a measure of the FFM that itself includes a disproportionate representation of maladaptive personality functioning across the domains. The current study also tests the hypothesis that the relationship of the FFM domains to problems in living parallels the definition of personality disorder as provided in the American Psychiatric Association’s (2000) diagnostic manual, concerning social impairment, occupational impairment, and distress. These hypotheses were tested in a sample of 79 persons who were within psychiatric treatment. The current study indicated that problems in living relate to the FFM domains in a meaningful manner and that these relationships correspond to the definition of personality disorder. Implications of the findings for future research are discussed.
