This study sought to identify the characteristics of stalking perpetrators who violated interim measures. For this purpose, 453 stalking court decision cases during the last two years (2022-2023) were collected. In detail, the study analyzed the group differences of interim measure compliant vs. violating perpetrator group regarding the demographics of perpetrators and victims, criminal demographics of perpetrators, stalking crime characteristics and perpetrator risk factors coded according to the Stalking Risk Assessment Scale (K-SAS). The main findings are as follows. Competing crimes, criminal histories on the same or similar crimes were significantly higher among the interim measure violating perpetrator group. Stalking offense characteristics regarding self/other harm threats, persistent and severity of stalking and also offender risk factors including anger and hostility, pathological obsession or suspicion, antisocial lifestyle, one-sided thinking, and interpersonal problems were higher among them. Finally, same crime recidivism and one-sided thinking were variables that significantly explained the violation of interim measures. Based on the findings, suggestions were made on additional protective measures in light of interim measure violation and ways to protect victims as well as preventing recidivism.
