Strong evidence exists that alcohol consumption and violent offending are linked, and the “common cause” model suggests that this link results from shared risk factors. To test this model and further explore the connection between alcohol consumption and violent offending, the present study used regression analysis to examine possible relationships among alcohol consumption, violent offending and personality characteristics (extraversion, neuroticism and psychoticism) in 1464 male prisoners aged 17 to 79 years who entered in Croatian prison system in 2013. and were evaluated in the Center for Diagnostics in Zagreb. The results suggest that alcohol consumption and violent offending share some personality risk factors, and that alcohol consumption mediates the relationship between personality and violent offending. These results are discussed within the framework of the common cause model, providing more detailed insights into the complex relationship among personality, alcohol consumption, and violent offending.
