Dysfunctional personality, Dark Triad and moral disengagement in incarcerated offenders: implications for recidivism and violence.

It is particularly important to study the underlying processes of the dysfunctional personality patterns and of antisocial behaviour in the prison population, to identify them and to analyse the functioning of the psychological mechanisms involved in these constructs. The main goal of this study was to analyse dysfunctional personality patterns, Dark Triad, moral disengagement mechanisms and their relationship with violence and recidivism. Participants were 63 incarcerated offenders in two prisons. The study found a higher degree of moral disengagement in the participants convicted for crimes involving the use of violence. The results indicated that antisocial and aggressive-sadistic tendencies were the dysfunctional personality traits most strongly associated with moral disengagement. The binary logistic regression analysis showed that the variables, which influenced recidivism in criminal behaviour, were the use of violence in the crime committed, antisocial personality traits, and advantageous comparison and dehumanisation as mechanisms of moral disengagement.
