For decades, there has been substantial research showing that ability tests effectively predict what people can do, but it is only in the last fifteen years that it has come to be generally accepted that personality is a useful predictor of what they will do. Much of this change in appreciation of the role of personality in predicting performance has been attributed to the application of the Five-Factor Model (FFM) of personality to personality-performance research. The FFM was developed on the basis of the lexical hypothesis, which states that it is advantageous for people to be able to accurately describe the behaviour of others, and therefore the most important dimensions of personality will be encoded in natural languages. An associated premise is that natural language descriptors refer to an individual's surface appearance or reputation (i.e., their observable behaviours), rather than the underlying processes or genotype of personality (i.e., people's cognitive and affective processing). This reasoning was used as the basis for most of the factor-analytical studies of personality descriptors within the English language, and one of the most robust factor solutions was the FFM. The FFM contains the personality dimensions Extraversion, Agreeableness, Conscientiousness, Openness to Experience and Emotional Stability. Although the FFM continues to evolve, particularly in response to cross-cultural research, the five basic dimensions appear to be remarkably consistent, and at least the core of each of these has been identified in the first six or seven factors found in every language considered to date. Of the five factors, Conscientiousness has been the one most reliably associated with workplace performance. Workplace performance itself has undergone a major reconsideration over the last fifteen to twenty years. Prior to that time, formal job roles and responsibilities were typically considered the start and finish of performance, but formal job requirements are now recognised as only one aspect of performance, which is increasingly referred to as Task Performance. Task Performance tends to change substantially from job to job, but there are other aspects of job performance, most notably Citizenship Performance, which appear to be consistent in most jobs. Citizenship Performance includes activities undertaken by an employee which facilitate Task Performance, such as making greater effort, complying with rules and procedures, and assisting others. Whereas Task Performance appears to be closely related to an individual's abilities, Citizenship Performance was originally proposed as an aspect of performance which is influenced by attitudinal and personality variables. Thus it has been proposed that Citizenship Performance largely mediates the relationship between personality variables, such as Conscientiousness, and Task Performance. However, this predictors of performance model has previously only been investigated in workplace settings. Yet performance is a relevant construct not only within workplace settings, but also within academic settings. In addition, the FFM dimension of Conscientiousness has been observed to be a reliable predictor of academic performance, just as it is a reliable predictor of workplace performance. Within educational settings, performance is typically tied to assessment measures, such as marks and GPA, which appear to measure academic Task Performance. However, no previous research appears to have considered whether Citizenship Performance mediates the relationship between Conscientiousness and Task Performance within an academic setting. Study One of this dissertation was designed to test this proposition. Participants in this study were 175 students enrolled within an introductory management subject. Participants provided assessments of their own personality using the Mini-Markers (Saucier, 1994), while Citizenship Performance ratings were provided by students' peers, at the end of a three-week group project. The hand-scored version of the Computerised Adaptive Rating Scales (CARS: Borman, 1999; Coleman & Borman, 2000) was used to assess Citizenship, but unfortunately the three scales of the CARS did not demonstrate good internal reliability. Consequently, a factor analysis was conducted to establish a new scale using the CARS items. This new scale, which was labelled Active Support, used six of the twelve CARS items and had satisfactory internal reliability. It was observed that the resulting scores on this Citizenship Performance scale were positively correlated with both Conscientiousness and academic Task Performance (as measured by grades). As predicted, Citizenship Performance entirely mediated the relationship between Conscientiousness and academic Task Performance. Therefore, the results of Study One were consistent with the predictors of performance model. It was concluded that Citizenship Performance is an important component of performance within academic settings, just as it is within workplace settings. Despite the fact that the relationship between both workplace and academic performance, and Conscientiousness, is reliable and well-established, correlations between Conscientiousness and performance tend to be moderate at best. Previous research has observed that other-rated measures of Conscientiousness have higher correlations with academic performance than do self-rated measures. Consequently, Study Two explored whether other-rated Conscientiousness improved the prediction of academic Citizenship and Task Performance, using a similar design to that utilised in Study One. One hundred and twenty-two students participated in Study Two while undertaking the same course as the students who had participated in Study One. Most of the results of Study Two were consistent with expectations, but there were some unexpected outcomes. Other-rated Conscientiousness was found to be a significantly better predictor of both academic Task and Citizenship Performance than was self-rated Conscientiousness. However, contrary to previous ideas, the relationship between other-rated Conscientiousness and Task Performance was not mediated by Citizenship Performance. In contrast, it was observed that the correlation between other-rated Conscientiousness and other-rated Citizenship Performance was .61 if both ratings were obtained from the same raters, and .44 if the two ratings were obtained from independent raters. When corrected for measurement unreliability, these estimates approached unity, which is consistent with the idea that, for the other-raters, Conscientiousness and Citizenship Performance were measuring the same construct. However, this study had several limitations, including its small sample size, the use of an unusual measure for Citizenship Performance, and the fact that it had been conducted in an academic setting. Therefore, there was a need to replicate Study Two before accepting that Conscientiousness and Citizenship Performance are actually much more strongly associated than previous research has indicated. In order to replicate Study Two, while addressing some of its limitations, a third study was conducted within a workplace setting. In Study Three, general staff supervisors within a public university were asked to rate their staff on measures of both personality and Citizenship Performance. In addition to Active Support, the measure used in Studies One and Two, two additional measures were included, which assessed the aspects of Citizenship Performance referred to as Individual Initiative and Helping Behaviour. The FFM dimension of Agreeableness was also added, because previous research indicates that, while Conscientiousness may be a better predictor of Individual Initiative, Helping Behaviour should be more closely associated with the FFM dimension of Agreeableness. However, using multiple ratings derived from the same raters can create common method bias in correlations, and so, in line with previous recommendations (Podsakoff, MacKenzie, Lee, & Podsakoff, 2003), Structural Equation Modelling (SEM) was used to control for this. The resulting correlations confirmed that there were strong relationships between the measures of Citizenship Performance and personality. Helping Behaviour had a strong relationship with supervisor-rated Agreeableness (.81), while Individual Initiative was significantly correlated with supervisor-rated Agreeableness (.44) and supervisor-rated Conscientiousness (.32). Active Support had strong correlations with these measures of personality (.57 and .55 respectively). The results of Study Three indicate that, for the participating supervisors, the Helping Behaviour dimension of Citizenship Performance is largely the same as the Agreeableness dimension of personality. Unlike Study Two, Active Support appeared to be not so closely associated with Conscientiousness, but instead seemed to occupy a position halfway between other-rated Conscientiousness and other-rated Agreeableness. Individual Initiative occupies a similar position, but is not so closely linked to these other-rated personality variables. Although these results suggest that, when compared with the students in Study Two, the supervisors in Study Three had a slightly different view of Active Support, it remains clear that much or most of the variance in each of these measures of Citizenship Performance is accounted for by these other-rated measures of personality. In order to understand why the strength of the relationship between the other-rated personality dimensions of Conscientiousness and Agreeableness, and the performance construct of Citizenship Performance, has been overlooked by previous researchers, it was necessary to reconsider the basic reasons for disagreement in ratings. Agreement between raters tends to vary considerably, depending on who is rating whom. Self-other agreement on ratings is typically modest, other-other agreement tends to be higher, but alternate-form and test-retest agreement are typically higher still. The reasons for this appear to be related to the extent to which ratings are produced using similar observations, and integrating these in similar ways, as well as the extent to which ratings are affected by specific aspects of individual rater-ratee relationships. Previous research has provided estimates for these effects which can be used to correct correlations for resulting biases. When these are applied to correlations between ratings of measures, such as performance or personality, which are provided by different other-raters, these correlations approximate unity. This includes the correlations, reported in this dissertation, between other-rated personality and other-rated Citizenship Performance. In conclusion, the results of the research reported in this dissertation are consistent with the idea that measures of Citizenship Performance are largely accounted for by other-rated measures of Conscientiousness and Agreeableness. It is argued that this conclusion is consistent with the lexical hypothesis which underlay the development of the FFM, as well as with the theoretical basis for the construct of performance. The dissertation concludes with a discussion of the implications of this conclusion, for a range of fields, including understanding the relationship between personality and performance, methodological consequences for future research, and practical implications for staff selection and performance appraisal systems.

Syfte: Syftet är att beskriva samband av revisorns bakomliggande psykologiska egenskapers påverkan vid värderingen av ett företags varumärke. Metod: Studien utgår ifrån en positivistisk vetenskapssyn där en kvantitativ ansats används. Teoretiskt perspektiv: Uppsatsens teoretiska kapitel utgår ifrån teorier om psykologiska variabler. De psykologiska variabler som i uppsatsen används är femfaktor-teorin samt riskbenägenhet. Empiri: Det empiriska materialet som används i denna studie är insamlat med hjälp av ett modellföretag samt en kompletterande enkät. Resultat: Studien i denna uppsats har visat att inga samband finns mellan revisorns psykologiska egenskaper samt dennes värdering av ett varumärke. Detta berör både faktorerna i femfaktor-teorin samt riskbenägenhet. Ett eventuellt samband finns mellan variablen agreeableness och varumärkesvärderingen,men då signifikans ej finns för hela modellen är det inget som statistiskt kan säkerställas. / Purpose: The purpose of this study is to describe the relationship of the auditor’s underlying psychological characteristics’ effect on the valuation of a brand. Methodology: This study applied a positivist concept of science with a quantitative research approach. Theory: The theoretical chapter is based on theories of psychological factors. The psychological factors in the essay is based on a five factor-model and risk preference. Empirical foundation: The empirical data used in this study was collected by a use of a model company and a supplemental questionnaire. Conclusions: The study in this paper has shown that no connection exists between the auditor's psychological characteristics, and his valuation of a brand. This affects both factors in fivefactor-theory and risk preference. A possible connection between the variable agreeableness and the value of the brand exists, but the significance was not present for the entire model, therefore it is not statistically ensured.

Ausgehend von den klassischen vier Paradigmen zur Messung individueller Differenzen wird die dominierende variablenzentrierte Forschungsausrichtung in der Differentiellen Psychologie hinterfragt und dafür plädiert, diese um einen personenzentrierten Ansatz zu ergänzen. Die Operationalisierung des personenzentrierten Zugangs erfolgt durch einen Prototypenansatz, der auf dem Fünf-Faktoren-Modell der Persönlichkeit basiert und dessen Potential und Grenzen in dieser Arbeit untersucht wurden. Zuerst wurde die Anzahl der Prototypen untersucht und diese Prototypenlösung anschließend validiert. Die auf Basis von zwei bevölkerungsrepräsentativen Stichproben sowie einer umfangreichen Internetstichprobe durchgeführten Analysen konnten übereinstimmend zeigen, dass anhand der ausgewählten multiplen Entscheidungskriterien eine Fünf-Cluster Lösung anderen Clusterlösungen vorzuziehen ist. Die Replizierbarkeit der Prototypen über unterschiedliche Stichproben verschiedenen Alters, Geschlechts, regionaler Herkunft, Bildungshintergrund, sozioökonomischem Status, Gesundheit (Allgemeinbevölkerung, Patientenstichproben), Erhebungsinstrumente (Selbst- und Fremdbeurteilungsverfahren, Fragebogen, Adjektivlisten, Papier-Bleistift-Verfahren und internetbasiert) und Extraktionsverfahren (Clusteranalyse, Mischverteilungsmodelle) zeigt, dass Persönlichkeitstypen eine Möglichkeit der Klassifikation von Personen nach der Ähnlichkeit ihrer Persönlichkeitsprofile darstellen. In vier Validierungsstudien konnten die Befunde zu emotionalen, kognitiven, verhaltensbezogenen und gesundheitsbezogenen Unterschieden zwischen den Prototypen im Erwachsenenalter repliziert und erweitert werden. Wie im Kindes- und Jugendalter zeigt auch der resiliente Prototyp im Erwachsenenalter die beste psychosoziale Anpassung. Für den über- und unterkontrollierten Prototyp lassen sich die Befunde einer hohen psychischen Belastung ebenfalls ins Erwachsenenalter übertragen. Der zuversichtliche und der reservierte Prototyp nehmen eine mittlere Position im Kontinuum der psychosozialen Anpassung zwischen dem resilienten und dem über- und dem unterkontrollierten Prototyp ein. Weiterhin wurden der variablenzentrierte und der personenzentrierten Ansatz hinsichtlich seiner Prädiktionsleistung verglichen. Anhand von zwei umfangreichen und heterogenen Stichproben konnten konsistente Zusammenhänge zwischen der Zugehörigkeit zu einem Persönlichkeitsprototyp und einer Vielzahl relevanter Straßenverkehrskriterien bestätigt werden. Abschließend wurde das Potential der Prototypen als Moderatoren geprüft. Es konnte demonstriert werden, dass die Prototypen den Zusammenhang zwischen dem CRP-Wert und der täglich verwendeten Dosis Prednisolon zur Behandlung der Symptome einer rheumatoiden Arthritis moderieren.

Due to the social environment transition and the health care reform, hospital¡¦s transformation has made the high cost nurse resource of the medical organization issue. While facing salary pressure and nursing shortages, nursing leadership has taken an important role in stabilizing/establishing a positive work environment and maintaining good health care quality and job performance. In the past, personality and leadership have been proved to relate to job performance, but few studies show the relationship between these three variables. This study investigates which dimensions of the Five-Factor Model of personality of the head nurse (HN) are related to job performance. This study also analyzes the HN and investigates whether leadership style moderates personality-job performance relations. This study carried out a survey research and secondary date analysis in three regional hospitals of Kaohsiung-Pingtung area. The sample included 35 HN and 174 nurses who worked with their HN for over 6 months. t-test was used to examine the difference of personalities and leadership style in different demographic variables. In addition, the Tobit regression model explained significant portions of variance in these criterions. Results support the hypothesis that openness and extraversion are positively related to job performance. Results also support the hypothesis that consideration is appeared to moderate relationships between openness and job performance. This study show that personality influences job performance. Moreover, it shows that the leadership style could be the moderator between personality and job performance. This study suggested that personality might be a crucial factor in selection and recruiting of head nurses. In addition, providing training in leadership will facilitate the job performance. This study suggests that future studies should increase the sample size in terms of decision making units as well as random selection from different hospital levels.

In recent years, because of the transition of global economic structure, competition between companies is changing toward knowledge management and innovation. Especially at the field of quickly changing product, the superiority of technology is always the key factor of competition. Today, R&D department is important in many companies. The efficiency of R&D not only depends on the ability of technology development but also on the skill of management. Therefore, innovative ability and R&D personnel behavior are important issues for companies. This study focus on the relationship between the innovative behavior of R&D personnel and its influencing factors that include personality traits of subordinate and leadership style of supervisor. The purpose is explored what factors affect the R&D personnel¡¦s innovative behavior. In addition, this study analyzes the influence of age, gender, education background, and etc., on innovative behavior. This study adopts Five Factor Model (Big Five) that includes Neuroticism, Extraversion, Openness to Experience, Conscientiousness, Agreeableness on the personality traits. In addition, the leadership styles contain the transformational leadership and the transactional leadership. Through a questionnaire survey, the following results are obtained: For the two influent factors, personality traits generate more effect toward the R&D personnel¡¦s innovative behavior than the leadership styles. Among the personality traits, Openness to Experience has the most contribution to innovative behaviors. For the leadership styles, transactional leadership would better encourage subordinates to behave innovatively.

The purpose of the study is to investigate the relationships among personality factors and life satisfaction in high school students. High school students ( N = 625) completed self-report measures of personality characteristics (namely, extraversion, neuroticism, openness, conscientiousness, and agreeableness) and global life satisfaction. Results include the specific contribution of each of these personality dimensions as they relate to life satisfaction, gender differences, and the role of perceived classmate support in relationships between personality factors and life satisfaction. Specifically, findings revealed that about 45% of the variance in adolescents‟ life satisfaction scores was accounted for by their self-reported measures of personality factors. Neuroticism emerged as the strongest predictor of life satisfaction. Further, results demonstrated that openness, conscientiousness, and extraversion were significant and unique predictors of life satisfaction. Gender differences were found in the link between agreeableness and life satisfaction such that a higher level of agreeableness was related to higher life satisfaction for girls, but not for boys. Finally, results of the structural equation model that analyzed the role of perceived classmate support in the link between personality factors and life satisfaction revealed significant paths between four personality factors (excluding openness) and perceived classmate support. Further, the path from extraversion to perceived classmate support showed the strongest standardized path coefficient (.42); suggesting that a higher score on extraversion was associated with a higher level of perceived classmate support which, in turn, predicted higher levels of life satisfaction. Neuroticism demonstrated the strongest, albeit inverse, direct path to life satisfaction, further supporting the finding that higher levels of neuroticism were related to lower levels of life satisfaction. Findings provide school psychologists with a better understanding of the demographic (i.e., gender), stable (i.e., personality) and interpersonal characteristics (i.e., perceptions of classmate support) that place students at-risk for negative outcomes via low life satisfaction or, conversely, facilitate optimal wellness via high life satisfaction.

The National Institute of Mental Health’s (NIMH) Research Domain Criteria (RDoC; Insel et al., 2010; Sanislow et al., 2010) were established in an effort to explore underlying dimensions that cut across many existing disorders as well as to provide an alternative to the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013). The present dissertation aimed to study one major component of the RDoC model, negative valence, as compared to other models hypothesized to be closely related, as well as its relationship to a key component of psychopathology, affective instability. Participants were adult community residents (N=90) currently in mental health treatment. Participants received self-report measures of RDoC negative valence, five-factor model (FFM) neuroticism, and DSM-5 Section 3 negative affectivity, along with measures of affective instability, borderline personality disorder, and social-occupational impairment. Through this investigation, a better understanding and potential expansion of this new model of diagnosis for clinicians and researchers is provided. In particular, it is suggested that RDoC negative valence is commensurate with FFM neuroticism and DSM-5 negative affectivity, and it would be beneficial if it was expanded to include affective instability.

Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income. With this new aspect on entrepreneurial research, we found that four out of five personality traits affect the material living standard among self-employed. Two out of the five personality traits, openness and extraversion, where found uniquely on self-employed. Among the control variables only gender and household income seemed to affect the material living standard, thus excluding the effect of age, hours of labour, education and household structure. This indicates that personality traits should be considered using while studying poverty among the self-employed.
