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.

The purpose of this study was to examine whether differences were found in occurrence of three personality traits from the Dark Triad, Machiavellianism, narcissism and psychopathy, in regards to students within different educations in universities and colleges in Sweden. Previous research and findings have shown that students with different educations tend to show traits from the Dark Triad of varying degrees. Data to the study was collected through a self-assessment survey named Short Dark Triad (SD3). The survey was translated to Swedish, then sent to 22 different educations at 33 Swedish universities and colleges. 1055 participants were gathered in the study with a distribution of 709 women and 346 men. The results were mostly supported by previous research, however a few results were not supported by previous research. For example, economy students did not get higher scores on Machiavellianism when compared to students at law and political science.

Syftet med studien var att undersöka om det gick att finna skillnader i förekomst av personlighetsdrag från den mörka triaden, det vill säga, machiavellism, narcissism och psykopati mellan studenter inom olika utbildningar på högskole- och universitetsnivå i Sverige. Tidigare forskning visar att studenter på utbildningar inom olika ämnen tenderar att uppvisa drag från mörka triaden i olika hög utsträckning. Data till studien samlades in genom att en enkät med självskattningstest Short Dark Triad (SD3) översatt till svenska skickades ut till totalt 22 olika ämnen och utbildningar vid 33 av Sveriges lärosäten. Totalt hade studien 1055 deltagare fördelat på 709 kvinnor och 346 män. Studiens resultat visade flertalet signifikanta skillnader gällande alla de tre personlighetsdragen mellan utbildningarna. Resultaten stämde i stora delar överens med tidigare forskning. Ett resultat som dock gick emot tidigare forskning var att ekonomistudenter inte fick högre poäng på machiavellism jämfört med studenter som läser juridik eller statsvetenskap. / The purpose of this study was to examine whether differences were found in occurrence of three personality traits from the Dark Triad, Machiavellianism, narcissism and psychopathy, in regard to students within different educations in universities and colleges in Sweden.
