3. Discussion
These two studies confirm that the relationship between socially deviant behaviours and trait EI is not straightforward. Generally considered a positive attribute, our results present evidence that higher levels of trait EI may actually facilitate both criminal and non-criminal deviant behaviours, especially among younger women and adult males. This research builds on the extant work of Bacon et al. (2014) by explicating the aspects of the trait which are most salient in helping to explain adolescent deviance in both males and females. In addition, we present preliminary investigations into how the EI profile of deviant individuals changes as they move through emerging adulthood and into full adulthood, lifestages when they should have normatively desisted from typical adolescent-limited behaviour.
For male participants aged 18–25, our results supported the prediction that deviant behaviours would be negatively associated with the trait EI factor Self-control, reflecting a tendency towards impulsivity, poor emotional regulation and difficulties managing stress. Overall, this is exactly the trait El profile we might expect in antisocial individuals given previous research on measures of similar constructs but measured independently of trait El, such as empathy and self-regulation (e.g. Cohen & Strayer, 1996; Downey et al., 2010; Jolliffe & Farrington, 2007). In contrast, for female participants, we predicted a positive association between trait El factors Emotionality and Sociability to support Bacon et al.'s suggestion that empathy, emotion perception, social skills and the ability to influence other people's feelings are associated with deviant behaviour in young female. Our results fully uphold this prediction.
