The current study examined divergences among impulsivity and sensation seeking items from the Zuckerman-Kuhlman Personality Questionnaire Impulsive Sensation Seeking scale in terms of their relations to other personality models, deviance, and laboratory task outcomes. A sample of 654 undergraduates was gathered across two studies and given a Five Factor Model of personality measure (e.g. NEO Five Factor Inventory, NEO Five Factor Report Form), deviance measures (e.g. Antisocial Behavior Inventory, Explicit Attitudes Towards Marijuana Questionnaire), and three laboratory tasks (e.g. Balloon Analogue Risk Task, Newmans Card-Playing Task). Results demonstrated the hypothesized divergences among impulsivity and sensation seeking items on measures of personality and deviance as well as laboratory tasks. We conclude that Impulsive Sensation Seeking is multidimensional and would be more useful if employed as two independent constructs: (Lack of) Premeditation and Sensation Seeking.

A stable and healthy personality is a requirement to deal effectively with the different stressors and demands that are part and parcel of a profession in education. Therefore, it is of the utmost importance to ensure that prospective teachers present well balanced personality profiles, which will enable them to become good teachers. Against the abovementioned background, this research study had the aim to: • by means of a literature study, determine the criteria that are generally used in the selection process of prospective education students nationally and internationally, and to determine the role and function of a personality assessment in the selection of prospective education students; • by means of a literature study, determine the characteristics of the desired personality profile of a teacher by applying the Five Factor Model of personality; • empirically determine the characteristics of the personality profiles of full-time registered education students at a higher education institution; • empirically determine whether there are differences between the personality profiles of 1) male and female education students; 2) education students in the different education phases; 3) education students with different home languages; 4) education students at different academic levels; and 5) education students who indicated education as first choice of study, and those who did not; and • to determine what the application possibility of the NEO-FFI is in the selection of prospective education students. The literature study produced the following results: • Academic criteria are mostly used in selecting education students, nationally and internationally and personality assessment does not play a role in the selection of education students in South Africa. • The desired personality profile of teachers, according to the Five Factor Model of personality, renders low scores on Neuroticism and high scores on Extraversion, Openness to Experience, Agreeableness and Conscientiousness. The empirical study produced the following results: • The group of education students generally presented the characteristics of the theoretical preferred personality profile with regard to Neuroticism, Extraversion, Agreeableness and Conscientiousness, but they presented relatively low mean raw scores for Openness to Experience. • No meaningful differences were found between the personality profiles of education students with regard to the education phase, home language, academic year and education as study choice, however, there were meaningful differences between male and female education students pertaining Agreeableness, where female education students presented higher mean raw scores than their male counterparts. Stanines were calculated to develop norms which can be used for personality assessment in the selection of prospective education students. Gender-specific norms were developed for this purpose. On grounds of the results of the investigation, it is recommended that personality assessment form an integral part of the selection process of prospective education students and that the NEO-FFI appears to be fruitful in this regard. / Thesis (MEd (Educational Psychology))--North-West University, Potchefstroom Campus, 2013

Personality tests are widely used in South Africa. The application of personality assessment techniques for clinical and personnel decisions has been a major activity for psychologists. All main personality models have ken developed in a Western context: the question therefore arises whether these models are adequate and sufficient for South Africa. There is a need to develop personality tests that are based on South African cultures. In South Africa the continuous use of Western-based personality tests raise a challenge. The challenge also lies with the current legislation with regard to the use of psychological tests. The challenge is to construct an inventory suited to the local needs while retaining the standards of validity and reliability expected of established assessment instruments. Our socially diverse society and its wide implications for the cultural dynamics of personality evaluations that we find in South Africa warrant further research. A qualitative research design was used in this study, including interviewing as a data gathering method. A total of 120 Tshivenda speaking people from the Thohoyandou district in Limpopo province and Pretoria in Gauteng province were interviewed. A total of 4 722 personality descriptors with a view to Tshivenda speaking people were obtained from the participants, and then translated into English. Content analysis was used to analyse, interpret and reduce these descriptors to a total of 150 personality characteristics which are the most important perspectives of personality for the Tshivenda speaking individuals. The personality characteristics were divided into eight categories, namely interpersonal relatedness, sociability, conscientiousness, emotionality, meanness, intellect, dominance and a category for other traits. The interpersonal relatedness factor in the Vhavenda personality characteristics could be regarded as a cultural factor. The Tshivenda speaking people are also sociable with a preference for companionship, social skills and numerous friendships. They also have a strong sense of purpose and high inspiration levels. The Tshivenda speaking people also experience emotions and feelings related to situations that they face. Intellect characteristics could also be extrapolated from the personality characteristics of the Vhavenda people. The findings of this study were compared to the five factor model, and evidence was found for extraversion and conscientiousness in particular. Very few characteristics of openness on the five factor model correspond to that of the Tshivenda speaking people, except in the cases of a few personality characteristics that were labelled under the category of intellect. Recommendations for future research are made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

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.

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.

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.

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.
