ABSTRACT
Background: Crime is a complex psychological, sociological and situational behaviour. Personality theories provide possible insights into the psychological aspects of crime. The primary assumption behind the personality theories is that crime and delinquency are related to the presence of some personality traits. Aims: To assess the personality dimensions of offenders, mentally ill offenders and to compare them with normal control population. Methods: A semi-structured interview consisting of Socio-demographic details, Eysenck Personality Questionnaire (EPQ) and Barratt Impulsiveness Scale (BIS-11) were used to assess the personality of offenders, mentally ill offenders and normal population. Results: Offenders with and without mental illness did not differ in their personality, but both the groups differed significantly with the personality of general population. The offenders were more impulsive compared to normal population in general and offenders with mental illness were scoring high on total BIS-11 score and on non-planning impulsivity score compared to normal offenders. Conclusion: Personality traits can predict the person’s vulnerability to commit an offence.
