Abstract

Personality profiling of violent and deceptive offenders is crucial, as these offenses indicate an offender's dangerousness. However, the personality differences between these groups remain unclear. The present study was conducted to comparatively examine the personality traits of these groups. This descriptive study uses a causal-comparative approach on a sample of 177 prisoners (91 violent and 86 deceptive offenders) at Tabriz Prison. Data were collected using the NEO Five-Factor Inventory (NEO-FFI), and analyzed through multivariate analysis of variance and logistic regression. The findings revealed that violent offenders scored significantly higher on "Neuroticism", whereas deceptive offenders had higher mean scores for "Conscientiousness," "Extraversion," "Openness to Experience," and "Agreeableness" (p < 0.05). Additionally, "Neuroticism" and "Conscientiousness" predicted the type of crime with an accuracy of %72.3. These findings indicate the existence of distinct personality profiles in these offender groups and their applicability in crime prevention and rehabilitation programs.
