Eysenck's theory of criminality and the personality types and offences of young delinquents

Personality Prototypes in Adult Offenders

“…To overcome some of the inconsistent findings, some authors (e.g., McEwan, 1983;McGurk & McDougall, 1981) introduced the idea of personality heterogeneity of offenders and the use of classification methods for differentiating them into subgroups. Results point to the importance of subtypes of criminal offenders and although the subtypes approach was welcomed as "an interesting development, which could be used fruitfully in future research" (Gudjonsson, 1997, p. 155), the majority of studies in crime and personality research neglect personality heterogeneity of the samples under investigation.…”
