Mobbning på arbetsplatser är ett stort samhällsproblem. År 2013 rapporterades 8 % av de arbetsrelaterade sjukdomar som anmälts till försäkringskassan vara orsakade av kränkningar, mobbning och trakasserier. Ohälsa, tvångstankar, ångest, depression, och posttraumatisk stress är vanligt förekommande hos de som utsatts för mobbning. Syftet med studien var att undersöka hur mörka personlighetsdrag samt ledarskapsstilar predicerar mobbning, baserat på data från observatörer av mobbning. Studiens två regressionsmodeller uppvisades en skillnad i varians, där den senare, som inkluderade även ledarens ledarstil och mörka personlighetsdrag, förklarade 8% mer av variationen i observerad mobbning än den modell som bara analyserade mobbaren. En rimlig slutsats är därför att ledarens ledarstil och mörka personlighetsdrag kan vara avgörande för förekomsten av mobbning. / Bullying at workplaces is a major problem among societys. In 2013, 8% of the occupational diseases reported to the Swedish insurance fund were reported to be caused by violations, bullying and harassment. Illnesses, obsessive thoughts, anxiety, depression, and posttraumatic stress are common in those who have been subjected to bullying. The purpose of the study was to investigate how dark personality traits and leadership styles predict bullying based on data from bullying observers. The two regression models in the study's showed a difference in variance, where the latter, which included the leader's leadership style and dark personality traits, explained 8% more of the variation in perceived bullying than the model that only analysed the bully, not including the leader. A reasonable conclusion is therefore that the leader's leadership style and dark personality traits can be decisive for the occurrence of bullying.

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.
