This study was based on The Big Five theoretical framework with focus on the extraversion factor, and its purpose was to assess how we value introverted and extraverted personality traits. A hypothesis was that ratings of extraversion-related adjectives would be higher than ratings of introversion-related adjectives. Another hypothesis was established to test if the ratings would differ between genders. The study included sixty-three participants (Age M = 23, SD = 3,6; 37 females; 26 males) who rated adjective words related to personality traits on the spectrum of introversion and extraversion on a Likert scale from one through seven. Results showed that extraversion related adjectives were rated higher than introversion adjectives and in terms of gender, males did not differ in their ratings of introversion and extraversion adjectives, however, females rated extraversion higher than introversion. In addition to considering personality adjectives as positive or negative, participants also answered the 20-Item Mini IPIP personality test, to explore whether our preference can be associated with our own personality. Results showed that the ratings of extraverted personality adjectives had a significant positive correlation with the extraversion factor in the IPIP, and the ratings for introverted adjectives showed a negative correlation, however it did not remain significant after a Bonferroni correction.

Government reports indicate that, on average, more than 3000 people die due to distracted driving each year, accounting for nearly 10% of all fatal car crashes. Other reports claim that two-thirds of fatal car accidents result from aggressive driving. Previous research has been inconclusive regarding how personality impacts distracted and aggressive driving behaviors. Therefore, the goal of this current study is to fill the gap in the literature concerning the role that personality plays in distracted and aggressive driving behaviors. We also explored the role that distracted and aggressive driving behaviors played in accident involvement. A sample of (N=327) participants were recruited using social media and the UCF SONA System. They were asked to self-report their driving behaviors and personality traits by completing a series of online questionnaires (ADBQ, BFI, DBQ, DDQ, DEMO, and IPIP NEO PI-R). Using this data, bivariate correlations were run using the Pearson Correlation Coefficients to determine the role that personality (OCEAN) plays in distracted and aggressive driving behaviors. We used the DDQ and the IPIP NEO PI-R to evaluate the relationship between personality and distracted driving, and we found that personality traits: Agreeableness, Conscientiousness, Extraversion, and Neuroticism were all significant predictors of distracted driving. Openness was the only one of the five personality traits to have no significant correlation. We used the ADBQ and the IPIP NEO PI-R to assess the relationship between personality and aggressive driving, and we found the same four personality traits: Agreeableness, Conscientiousness, Extraversion, and Neuroticism were all significant predictors of aggressive driving. Openness was, again, the only one of the five personality traits to have no significant correlation. Backward regression analyses were performed to determine what caused these relationships. The regression analysis displayed trait subscales: Morality, Cooperation, Self Discipline, Activity Level, Excitement Seeking, Anger, Emotionality, and Liberalism, each significantly contributed to driver distraction. Another backward regression analysis reveals trait subscales: Morality, Self-Efficacy, Dutifulness, Self Discipline, Anger, and Artistic Interests, each significantly contributed to driver aggression.

Dark triad är en kombination av mörka personlighetsdrag som består av subklinisk psykopati, subklinisk narcissism och machiavellism (Paulhus & Williams, 2002). Jones och Paulhus (2013), utvecklade Short Dark Triad (SD3), ett test som mäter dark triads personlighetsdrag. Den föreliggande studiens syfte var att validera en svensk version av SD3. Respondenterna svarade på nio enkäter som ingick i ett forskningsprojekt varav tre användes till denna studie. Respondenterna (N = 103) var mellan 19 och 64 år, och alla var aktiva i arbetslivet. Konvergent validering gjordes genom korrelationsanalyser som kontrollerade sambanden mellan de delar, i beprövade instrument, som mäter personlighetsdrag relaterade till begreppen subklinisk psykopati, subklinisk narcissism och machiavellism. Sambandsanalyserna gjordes mellan SD3 och IPIP-120 som mäter femfaktormodellens dimensioner, samt Swedish universities Scales of Personality (SSP) som grundar sig på biologiska markörer för olika psykiatriska tillstånd. Resultaten gick i huvudsak i linje med tidigare forskning (Furnham, Richards, Rangel, & Jones, 2014) med avseende på sambanden mellan femfaktormodellens dimensioner och SD3. En gemensam kärna i de tre personlighetsdragen i dark triad var ovänlighet, och ett viktigt resultat var de signifikanta negativa sambanden med femfaktordimensionen vänlighet. Den Svenska versionen av SD3 anses validerad. / Dark triad is a group of three dark personality scales consisting of subclinical psychopathy, subclinical narcissism and Machiavellianism (Paulhus & Williams. 2002). The Short Dark Triad (SD3), is the measuring tool and was developed by Jones and Paulhus (2013). The purpose of this thesis was to validate a Swedish translation of the SD3. This was done within an existing research project and included 103 respondents, aged 19-64 years, all being employed. They were assigned to respond to nine different surveys, three of them measuring psychopathy, narcissism and Machiavellianism-related scales. Convergent validation was done by correlation analysis with IPIP-120, measuring the personality of five factor model and Swedish universities Scales of Personality (SSP), measuring personality traits based on biological markers, and how well they measure the SD3. Our results generally confirm earlier research on studies between five factor models personality scales and SD3 (Furnham, Richards, Rangel, & Jones, 2014). One result of particular importance was the negative correlation with the Agreeableness Scale since it is a core for the dark triad personalities. Furthermore, our results followed the expected patterns in the correlations between dark triad personalities and the five factor model. The result of our thesis concludes that the Swedish translation of thPSKe SD3 test is to be considered valid.
