Rationalizing criminal behaviour: the influence of criminal sentiments on sociomoral development in violent offenders and nonoffenders.

Cognitive developmental theory suggests that mature-level sociomoral reasoning (Stages 3 and 4) can provide a protective factor, or buffer, against antisocial and violent criminal behavior. This study explored whether the influence of internalised criminal sentiments could undermine this buffer. The sample was high-risk men and women offenders (n = 99) convicted of serious violent index offences, and men and women nonoffender university students (n = 101).
