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.

Tidigare forskning menar att det äldsta syskonet anses vara mer auktoritärt, det mellersta barnet minst familjeorienterat och det yngsta barnet mer socialt. Uppväxten kan påverka individens KASAM. Studien undersöker om syskonplacering samverkar med människors KASAM, personlighet utifrån femfaktormodellen samt ser till eventuella könsskillnader. Urvalet bestod av högskolestudenter, varav 145 kvinnor och 80 män. Enkätens material analyserades med tvåvägs variansanalyser. Studien uppvisade ingen signifikant skillnad mellan de tre syskonplaceringarna. En tendens till signifikant interaktion visades mellan könen, där kvinnliga mellanbarn har lägre KASAM än de manliga. Studien visade två signifikanta könsskillnader mellan kvinnor och män. Kvinnorna var mer neurotiska och samvetsgranna än männen. Resultatet uppvisade en tendens till signifikans, gällande att kvinnor hade högre grad av personlighetfaktorn öppenhet än männen. Slutligen konstaterades att syskonplaceringen inte samverkar med individens personlighet eller KASAM, men att det finns vissa personlighetsskillnader mellan könen. Resultatet kan bero på brister i studien, som att familjekonstellation inte tillfrågades deltagarna.

Researchers emphasize the role of cognitions in sex offenders' molesting behaviors. Although cognitions are important, little research has examined child molesters' thoughts about themselves in relation to their engagement in treatment. In this study, the NEO-Personality Inventory (NEO-PI-R) was administered to 67 child molesters. Child sexual offenders rated themselves and their view of a typical child molester using two NEO-PI-R versions. The degree to which child sex offenders identify themselves with their view of a typical child molester, and this agreement's relation with engagement in treatment, were investigated. The view that child sex offenders hold about themselves in relation to a typical child molester showed no relation to treatment engagement or length of time in treatment. However, this self-perception was related to the number of children abused.

The trait approach to personality is one of the most influential epistemological frameworks in personality psychology and underlies the development of most objective personality inventories. The Revised NEO Personality Inventory (NEO-PI-R) is amongst the most widely used operationalisations of the FFM within personality assessment (Costa and McCrae, 1992). However, recent research (Franklin, 2009; Laher, 2010) suggests that the NEO-PI-R is not wholly applicable within the South African context; as there may be inappropriate items contained within the inventory, both linguistically and culturally. Within the United States, McCrae, Costa and Martin (2004) identified the NEO-PI-R as having specific problematic items, and developed the NEO-PI-3 as a revised “more readable” version of the NEO-PI-R. Thirty-seven items were changed from the original 240 items in the NEO-PI-R to create the NEO-PI-3. However, the modifications made to the NEO-PI-3 did not address all the issues pertinent within the NEO-PI-R from a South African perspective as evidenced in Laher’s (2010) and Franklin’s (2009) studies. This study adapted the NEO-PI-3 by changing specific items informed through Franklin (2009) and Laher’s (2010) research, as well as research conducted within this study on two samples of university lectures at the University of the Witwatersrand. Forty-nine items were changed from the original 240 NEO-PI-R items, retaining 30 items changed from the NEO-PI-3, and preferring 3 of the original NEO-PI-R items to the NEO-PI-3 items. These changes were aimed at making the NEO-PI-3 a more appropriate and applicable instrument both culturally and linguistically within the South African context. This modified inventory was then administered to 175 students at the University of the Witwatersrand to test the inventory’s validity and reliability. The reliability of this modified inventory was assessed through conducting an internal consistency analysis generating alpha coefficients indicating that the inventory was indeed reliable. The construct validity of this modified inventory was assessed through an exploratory factor analysis where five factors did emerge from the analysis; concomitant with the theoretical basis of the FFM. Based on feedback from the participants, both quantitatively and qualitatively, recommendations for future research and further problematic items are identified and discussed. In terms of the reliability of the modified version of the NEO-PI-3, internal consistency coefficients produced within the study suggested that the instrument is reliable, producing moderate to good alpha values, as well as producing evidence of good construct validity. Only 17 items emerged as still being potentially problematic within the modified version of the NEO-PI-3.

The aim of this study was to examine the association between personality and risk taking in a sample of 461 older adults from the Charlotte County Healthy Aging Study (CCHAS). The personality factors of openness to experience, extraversion, neuroticism, agreeableness and conscientiousness were measured with the NEO Five Factor Inventory. Risk-taking was measured with an 8-item questionnaire and a single-item question that assessed subjects' participation in sensation seeking behaviors. Spearman correlation coefficients, hierarchical linear regression and hierarchical logistic regression were used to assess the association. As consistent with past research, high scores on openness to experience (beta = 0.16, P<.0001) and low scores on neuroticism (β = -0.14, P<.01) and agreeableness (β = -0.16, P<.01) were associated with the total score of the 8-item risk taking questionnaire. The single-item risk question was also associated with openness [OR = 1.09; 95% CI: 1.05-1.13], neuroticism [OR = 0.94; 95% CI: 0.90-0.97] and agreeableness [OR = 0.95; 95% CI: 0.92-0.99]. After stratifying by gender, only openness was still significantly associated with risk-taking. Interaction terms including gender and personality factors were added to the models to test if gender was an effect modifier. Although personality differences existed between men and women, none of the interaction terms were statistically significant.

The predominant model of general personality structure is arguably the Five Factor Model (FFM), consisting of the five broad domains of neuroticism, extraversion, openness, agreeableness, and conscientiousness. The FFM of personality disorder (FFMPD) has proposed maladaptive variants at both poles of the FFM. The purpose of the current study was to identify a subset of FFMPD scales, utilizing factor analysis, that illustrate, and provide a potential measure of, the bipolarity present in the FFMPD. All of the FFMPD scales were administered to 443 community participants recruited from Amazon Mechanical Turk. Bipolarity was evident in a series of factor analyses of subsets of FFMPD scales, with the exception of openness. The current study also demonstrated that the presence of bipolarity is impaired by a number of concerns, including the presence of non-diametric scales, bloated specific factors, general factor of personality disorder, and occupation of interstitial space.

Finding what is alike among the personalities of creative people has been a dream of many researchers. No single personality type has been discovered as prototypical, yet the promise of common attributes among creative people remains enticing. This study examines one of these promising characteristics - Openness to Experience, a personality factor from the Five-Factor Model. This factor has been shown to correlate positively with creativity in past studies. In the present study this relationship was partially confirmed in a sample of employees whose jobs require technical problem solving, by correlating the employees self-rated Work-specific Openness to Experience and NEO PI-R Openness with supervisory ratings of their creative work performance. The Work-specific Openness scale demonstrated a significant correlation with supervisory ratings of creativity, whereas the NEO PI-R Openness scale did not. Although none of the NEO PI-R facets were significant predictors of criterion, four Work-specific facets were significant predictors based on zero order correlations. These facets are Openness to Ideas, Fantasy, Values, and Actions. However, although individual facets of Openness were expected to differ in validity, the magnitude of their correlations with creative performance scores did not differ significantly. Convincing results showing incremental validity of the Work-specific scale over the NEO PI-R scale are also discussed.

The focus of this dissertation is exploring personality factors that impact performance within a small insurance agency. The primary research question is, what is (or are) the best personality factor(s), sub-facets, or constructs, that contribute to increased performance within an insurance agency. Three of the Five-Factor Model dimensions, extroversion, conscientiousness, and openness to experience along with grit and hardiness were examined, as well as their sub-facets. Grit and hardiness were not found to add additional explanation of the variance while five of the sub-facets were found to better explain the variance over the composite dimensions.

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.
