Prevention of recidivism is the most important goal of today's criminal justice system. The aim of this study, which was designed in a cross-sectional design, was to examine the impulsivity levels and addiction characteristics of convicts with recidivism behavior and to reveal the factors that may be related. The sample of the study consisted of 230 male convicts in four different penal execution institutions; 100 of whom having a one-time offense history, and 130 with a history of recidivism. Personal information form, Barratt Impulsiveness Scale-11 (BIS-11) and Addiction Profile Index (API) were used as data collection tools. The findings of the study showed that lifetime substance use and risky substance use rates of recidivists were statistically significant compared to those without recidivism; impulsivity scores of recidivists were significantly higher than those of first-time offenders; and impulsive behavior increased as the severity of addiction increased in recidivists. As a result of the research, it was revealed that substance use and impulsivity may be a risk factor for re-offending. In this sense, it is thought that it is very important to carry out intervention programs effectively in both penal institutions and probation directorates within the criminal justice system in order to prevent recidivism and support rehabilitation.
