The dark side of Facebook®: The Dark Tetrad, negative social potency, and trolling behaviours

• Problematic psychological effects for victims of trolling
• Identifying characteristics of ‘trolls’ will aid psychological intervention.
• Facebook® trolling behaviours predicted from personality and motivation.
• Personality traits were the Dark Tetrad, motivation was social reward.
• Trolls higher on trait psychopathy, sadism, and negative social potency

Trolling behaviours on social networking sites (SNSs) are problematic for other computer mediated communication users, as the psychological effects of experiencing trolling online are considered similar to the psychological effects of offline harassment. The current study explored personality traits and social motivations associated with individuals who engage in online trolling, specifically on the SNS Facebook®. The Dark Tetrad personality traits (i.e., narcissism, Machiavellianism, psychopathy, and sadism) and social reward (specifically, negative social potency) were examined for their predictive utility of trolling behaviours on Facebook®. A sample of 396 adults (75.9% women, 24.1% men) aged between 18 and 77 years of age (M = 34.41, SD = 1.70) completed the Global Assessment of Facebook® Trolling (GAFT), The Dirty Dozen, The Short Sadistic Impulse Scale, and The Social Rewards Questionnaire. Results showed that trait psychopathy and sadism predict Facebook® trolling behaviours; however, negative social potency had the strongest predictive utility. These results show that individual trolling behaviour may be better explained by negative social reward motivation than negative personality traits. In addition, these findings offer practical implications for SNS administrators and everyday users of SNSs. Future research should continue to explore predictors of this understudied antisocial online behaviour.
