The Relationship between Personality and Job Performance in Sales: : A Replication of Past Research and an Extension to a Swedish Context

Klang, Andreas January 2012 (has links)
This study examined the relationship between personality dimensions and supervisory ratings of job performance, in a sales context in Sweden. A sample of 34 telesales workers, employed at two major telecom companies, completed the NEO PI-3 (McCrae & Costa, 2010). As hypothesized, it was found that Extroversion, Conscientiousness, and Neuroticism correlated moderately with job performance. In line with past research, this suggests that individuals, who display high levels of Extroversion and Conscientiousness, as well as low levels of Neuroticism, perform better in sales related occupations. Unlike hypothesized, no correlation was found between job performance and Agreeableness and Openness to Experience. Additional computations indicated the importance of specific sub dimensions of Extroversion and Conscientiousness in respect to job performance. Practical implications in respect to recruitment and directions of future research are discussed.

Generalized Identification : Individuals’ levels of identification with groups and its relation to personality

Manninen, Elina January 2016 (has links)
This thesis investigates a newly developed term coined by the author called generalized identification, which is the tendency that people who identify high with one group tend to identify high with other groups as well, and how personality variables from the Five-Factor model may relate to this tendency. A common component of identification towards 10 preselected groups was calculated (N = 148), with a principal component analysis. The result reveal that the generalized identification account for 41 % of the total variance. A stepwise multiple regression analysis further showed that Openness to Experience and Agreeableness from the Five-Factor model explained 26 % of the variance in the generalized identification. However, due to low reliability when measuring personality traits, the relationship between personality and generalized identification could not be interpreted in a satisfying way, and it needs to be further explored before drawing firm conclusions.

COMPARING PERSONALITY DISORDER MODELS: FFM AND DSM-IV-TR

Samuel, Douglas B. 01 January 2008 (has links)
The current edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; American Psychiatric Association, 2000) defines personality disorders as categorical entities that are distinct from themselves and from normal personality traits. However, many scientists now believe that personality disorders can best be conceptualized using a dimensional model of traits that span normal and abnormal personality, such as the Five-Factor Model (FFM). Many research studies have indicated that the current personality disorder system can be adequately conceptualized using the FFM. However, if the FFM or any dimensional model is to be considered as a credible alternative to the current model, it must first demonstrate an increment in the validity of the assessment offered within a clinical setting. Thus, the current study extended previous research by comparing the convergent and discriminant validity of the current DSM-IV-TR model to the FFM across four assessment methodologies. Eighty-eight individuals that were currently receiving ongoing psychotherapy were assessed for the FFM and the DSM-IV-TR personality disorders using self-report, informant report, structured interview, and therapist ratings. The results indicated that the FFM had an appreciable advantage over the DSM-IV-TR in terms of discriminant validity and, at the domain level, convergent validity. Implications of the findings for future research are discussed.

USING THR FFM TO UNDERSTAND AND INTEGRATE THE DEFICITS OF PSYCHOPATHY

Derefinko, Karen J. 01 January 2009 (has links)
Psychopathy is associated with several behavioral and psychophysiological deficits. Lynam (2002) has argued that the use of an overarching conceptualization of psychopathy can provide a parsimonious explanation of psychopathic pathology. The current study examined relations between tasks used to explore psychopathic pathology and dimensions from the Five Factor Model of personality. Undergraduate participants completed the NEO PI-R, the BART, a go/no-go task, an emotional morph task, and provided physiological responses to stimuli. While hypothesized relations to FFM psychopathy composites were generally unsupported, other interesting relations to traits were identified. Results indicated that hypoarousal to negative stimuli was negatively related to pan-impulsivity. Maladaptive risk taking was positively related to panimpulsivity and high self-directed negative affect. Response modulation deficits were negatively related to pan-impulsivity, low self-directed negative affect, and facets of openness. Deficits in empathic responding were positively related to other-directed negative affect and self-directed negative affect, and negatively related to pan-impulsivity and interpersonal assertiveness. Although it remains unclear whether the failure to support hypotheses was related to the study variables or population, results indicate that the FFM can provide additional information with regard to what deficit tasks assess.

The establishment of implicit perspectives of personality in Tshivenda-speaking South Africans / Rejoyce Talifhani Ntsieni

Ntsieni, Rejoyce Talifhani January 2006 (has links)
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.

Exploring Psychopathic Personality Traits and Moral Development in a Non-criminal Sample

Bewsey, Kyle 05 1900 (has links)
This study explored psychopathic personality traits among a non-criminal, college undergraduate sample. Much research has been done on conceptualizing the construct of psychopathy, but this work has been conducted primarily with incarcerated individuals using a structured interview, The Psychopathy Checklist – Revised (PCL-R; Hare, 1991, 2003). The goal of the current study was to assess psychopathic traits among non-criminal individuals using The Self-Report Psychopathy Scale - Version Four (SRP-IV; Paulhus, Neumann, & Hare, in press), and compare how SRP-IV scores were associated with a well recognized semi-structured interview for psychopathy, The Psychopathy Checklist – Screening Version (PCL: SV; Hart, Cox, & Hare, 1995). The study also examined whether psychopathic personality traits could be predicted using a measure of normal-range personality, based on the five-factor model (FFM; Digman, 1990), and a measure developed by Loevinger (1976) related to ego development. Five-Factor Model Rating Form (FFMRF; Mullins-Sweat, Jamerson, Samuel, Olson, & Widiger, 2006) scores and Total Protocol Ratings (TPR score) on the Washington University Sentence Completion Test (WUSCT; Hy & Loevinger, 1996) were used to predict psychopathy scores. Correlations of SRP-IV scores and PCL: SV scores with FFMRF scores and WUSCT TPR scores were also examined for their uniformity. As predicted, there were significant, negative correlations between FFM domains, Agreeableness and Conscientious, and SRP-IV scores, as well as significant, negative correlations between WUSCT TPR scores and SRP-IV scores. These correlations ranged from small to strong for both SRP-IV overall scores and for SRP-IV factor scores (i.e., Interpersonal Manipulation, Callous Affect, Erratic Lifestyle, and Criminal Tendencies). Additionally, FFM domain scores and WUSCT TPR scores significantly predicted SRP-IV scores. FFM domains, Agreeableness and Conscientiousness, and WUSCT TPR scores, were the strongest predictors of SRP-IV scores. Similar results were found when FFM domain scores and WUSCT TPR scores predicted SRP-IV factor scores. Results also indicated Agreeableness and Conscientious explained an additional 24% of the variance in psychopathy scores, after controlling for WUSCT TPR scores. Conversely, WUSCT TPR scores explained an additional 5% of the variance in psychopathy scores after controlling for Agreeableness and Conscientiousness. Finally, as predicted, the differences in correlations between psychopathy scores (i.e., PCL: SV, SRP-IV), and Agreeableness, Conscientiousness, and WUSCT TPR scores were not statistically significant providing evidence that correlates of psychopathic traits can be measured among non-criminal individuals using a self-report measure, the SRP-IV, and that these findings are concordant with those based on a standardized structured assessment for psychopathy. Limitations of the study, implications, and recommendations for future research are also discussed.

Personality and Neurobiology : A Review of Fronto-Limbic Structural and Functional Connectivity in Neuroticism

Jedbäck, William January 2019 (has links)
Background: The five-factor model is the most prominent theory in personality science which aspire to understand the thoughts, feelings and behavior of individuals, determined by five relatively stable domains. Neuroticism, defined as a higher threat reactivity and susceptibility to negative affect, is one domain which has proven problematic for well-being, and has estimated societal costs of approximately 2.5 times that of common mental disorder per 1 million inhabitants. Problem: The neural correlates of neuroticism could supply research with a fundamental base of understanding the trait, however, due to scattered founding’s of segregated activity in brain structures relative to neuroticism, meta-analyses argue that increased understanding of global rather than local organization, could be more fruitful for the investigation. Methodology: Since neuroticism is convergent with emotional instability, two structures of interest with regards to global organization are the amygdala, crucial for emotion generation, and the prefrontal cortex (PFC), responsible for emotion interpretation and emotion regulation. Reviewing brain imaging research conducted with emphasis on integrative communication between the amygdala and the PFC in individuals with high trait neuroticism has therefore been the main objective of this thesis. Results/conclusion: According to the investigated research there is compromised structural integrity correlated with neuroticism, while the research on functional communication between the structures explored is not yet sufficiently covered to supply a satisfactory answer. Some of these neurobiological findings are in line with personality science observation in neuroticism, and could hence contribute to the investigation. However, more research is warranted in this field of neuroscience.

The relationship between the five-factor model and individualism/collectivism among South African students

Vogt, Liesl Therese 03 October 2008 (has links)
The Five-Factor Model (FFM) of personality is one of the prominent models in contemporary psychology and defines personality in terms of five broad factors, namely, Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness. Recent research, however, questions the applicability of the FFM in non-Western cultures, suggesting that it is not exhaustive enough and that it does not account for some other personality factors, most notably Individualism/Collectivism. Therefore, this study investigated whether the FFM of personality is related to Individualism/Collectivism in a sample of South African students. A total of 176 questionnaires were completed by students from the University of the Witwatersrand. The questionnaire contained the individualism/collectivism (INDCOL) scales and the Basic Traits Inventory (BTI) which is a South African instrument based on the FFM. Results indicate that there were no significant relationships between the five factors and Individualism/Collectivism. In addition no significant difference was found between race and the five factors and Individualism/Collectivism. There were also no significant differences between home language and the five factors and Individualism/Collectivism.

Exploring language bias in the NEO-PI-R

Franklin, Dee Ross 08 March 2010 (has links)
The study explores language bias in the NEO-PI-R both quantitatively and qualitatively. A sample of 28 postgraduate psychology student volunteers completed a questionnaire containing the NEO-PI-R and two open-ended questions about the instrument. These responses were then analysed across English first language and second language speakers to explore issues of bias. Reliability of the NEO-PI-R appeared to be robust at a domain level. The reliability of the facets, while appropriate for the most part, still yielded low alpha coefficients for the Excitement-seeking, Actions, Values and Straightforwardness facets. ANOVA’s at the domain and facet scale levels indicated no significant differences across home language. However ANOVA’s at the item level yielded 33 in total that were problematic, comprising of 12 items that were significant at the 5% level of significance and 21 items at the 10% level of significance. These items were primarily from the N and E domains. Thematic analysis of the open-ended questions of the questionnaire indicated 26 items were difficult to understand and/or inappropriate for the South African context. These items were primarily from the E and A domains. From the original sample of 28 volunteers, two focus groups were formed, comprising of volunteers from the initial sample. The focus groups explored several qualitative issues, including concepts of personality, language and culture and the applicability of the NEO-PI-R for South African user groups. It was perceived that there is a presence of American socio-cultural references within the use of language, grammar and socio-cultural context in the instrument. Thus the results show evidence of language bias in the NEO-PI-R, and subsequently identify particular aspects and items of the instrument that are especially problematic for a South African user group. The present study suggests that the NEO-PI-R would need to be revised to suit the South African context by changing the problematic items.

Five Factor Personality Traits in Schizophrenics with a History of Violent Behavior

Lust, Ashley 01 January 2017 (has links)
The diagnosis of schizophrenia has been associated with increased risk of violence and aggression. However, the extent of this association in relation to displayed personality traits among individuals diagnosed with schizophrenia have not been fully investigated. The lack of research has resulted in an inability to determine why only some individuals with schizophrenia display violent tendencies when others do not. Guided by Costa and McCrae's five-factor model of personality and Eysenck's theory of personality and crime, the purpose of this study was to investigate the relationship between the five personality traits and the display of violence among individuals with schizophrenia, as well as the predictability of violence. A personality assessment was used to explore the personality of the participants (n = 111), individuals obtained by convenience sampling of data originally collected by Ohi, Shimada, and Kawasaki. Each of the participants included had been diagnosed with schizophrenia by at least two clinical physicians. One-way analyses of variance were performed for each of the five personality traits in order to distinguish any relationships. A binary logistic regression model was conducted in order to discover a model of predictability in regards to violent behavior among individuals with schizophrenia. Results confirmed previous research findings of a statistically significant relationship between neuroticism and violence. However, adding to the research was the result of a significant contribution of neuroticism in the prediction of violence among schizophrenics. Positive social changes arising from these findings include practitioners having the future abilities of designing specific treatment options for individuals diagnosed with schizophrenia based on personality.
