Personlighet och dess betydelse för beteende har under lång tid varit ett lika aktuellt som välundersökt forskningsområde. Denna studie syftar undersöka sambandet mellan personlighetsdrag enligt Five Factor Model och musikpreferenser i en svensk population. Resultaten förväntas ligga i linje med tidigare studiers, vilka funnit vissa positiva samband bl. a. mellan Extraversion och konventionell musik samt Öppenhet för erfarenheter och traditionell, komplex musik. Deltagarna (107) svarade på ett webbaserat formulär avsett att mäta musikpreferenser    och    personlighetsdrag.    Musikpreferenstestet utgjordes av 22 genrer varav 20 ingick i en analys resulterandes i sex musikdimensioner. Resultaten visade bl.a. att Öppenhet för erfarenheter    korrelerade    positivt    med    musikdimensionerna Amerikansk traditionell och Europeisk traditionell och Extraversion korrelerade positivt med Konventionell musik. Vidare fanns även könsskillnader vad gällde musikpreferenser. Resultaten följde tidigare forskning trots vissa metodologiska skillnader, vilket ger ytterligare tyngd åt kopplingen mellan musikpreferenser och personlighetsdrag.

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.

There is relatively little research based on the Big Five personality dimensions and job satisfaction and the relationship thereof. Job satisfaction of employees is a good indication of organisational effectiveness and is influenced by organisational and dispositional factors. The fundamental nature of the dispositional approach is that individuals have stable traits that significantly influence their affective and behavioural reactions to organisational settings. Job satisfaction can be considered a general feeling of well-being experienced by any employee about the work he or she does or as a related collection of attitudes about various aspects of the job. Employees, who perform at higher levels, will most likely make a greater contribution in the organisation. These individual's are more likely to achieve greater status; thus the importance of having satisfied employees in any organisation. The general objective of this study was to determine the relationship between personality dimensions and job satisfaction of engineers in a petro-chemical organisation. A cross-sectional survey design was used in the empirical study. The sample consisted of 89 junior to middle level engineers within a petro-chemical organisation. The Minnesota Job Satisfaction Questionnaire (MSQ) and the Personality Characteristics Inventory (PCI) were administered. Descriptive statistics were used to analyse the data. Cronbach alpha coefficients, inter-item correlation coefficients and confirmatory factor analysis were used to assess the reliability and validity of the measuring instruments. Pearson and Spearman correlation coefficients were used to specify the relationships between the variables. Multiple regression analysis was used to determine which personality dimensions were the best predictors of job satisfaction. The current research found that employees who are more stable and introverted tend to be more satisfied with achievement, independence as well as human and technical supervision at the work place. It was also established that extraverted and sociable individuals in the organization are less satisfied with human supervision. The findings of this research showed that some personality dimensions are related to aspects of job satisfaction However, overall personality dimensions explained relatively small percentages in the variance of job satisfaction. Because of this, the situational frame of reference, which is most common at present within the workplace, as well as the frame of reference that most supports this research, job satisfaction/dissatisfaction, is alleged to result from the nature of the job or h m the conditions at work. This basically epitomizes the effects of situational forces on workers' job attitudes. The results showed that subscales predicted job satisfaction to a greater extent than personality dimensions. Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2004.

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.

The ability to control one’s behaviour is a fundamental cognitive function subserved by the prefrontal cortex (PFC). Whereas the neural basis of inhibitory control is reasonably well-established, the possible influence of individual differences in personality on cortical activity associated with this ability remains largely unexplored. The present study obtained self-report ratings of Five-Factor Model personality traits from 42 healthy adults while hemodynamic oxygenation in the PFC was recorded during a Go/No-Go task. Results indicated that Neuroticism, Agreeableness and Openness to Experience were associated with attenuated activity in the lateral PFC, a region critical for emotion regulation and behavioural control, whereas Extraversion and Conscientiousness were associated with greater activation in these regions. Activity within the medial PFC, an area linked to task engagement and self-monitoring, shared a positive association with Agreeableness. These findings provide important insights into how neural systems supporting inhibitory control may be affected by individual differences in personality.
