INTRODUCTION AND RESEARCH GOAL: Aggressive behavior by patients in psychiatric institutions is a global problem that results in physical and psychological injuries to staff. Violence against nurses/technicians in hospital psychiatry is a frequent issue with serious consequences. The aim of this study was to determine the frequency and types of aggression by psychiatric patients towards nurses and technicians. RESPONDENTS AND METHODS: The study was conducted on a convenience sample of 120 respondents via an online questionnaire during April and May 2024. RESULTS: 92.5% of nurses/technicians experienced some form of aggressive behavior, with verbal aggression being the most common (92.5%), followed by physical aggression (61.7%) and sexual aggression (5%). The highest frequency of aggression was recorded in acute and forensic psychiatric wards. Most respondents (72.1%) reported the aggression to the relevant authorities, indicating a high awareness of the importance of reporting violence. Although men reported aggression more often, no statistically significant difference was found between genders. Most respondents (85.0%) stated that they do not feel safe at work, and those who believe that protection and security are inadequate reported higher levels of experienced aggression. CONCLUSION: Most nurses/technicians do not feel safe, with higher levels of experienced aggression among those who believe that protection and security are inadequate. Although aggression is common, there are no statistically significant links between the age, gender, or workplace of nurses/technicians and the frequency of aggression, suggesting that aggression does not discriminate based on these demographic factors. However, gender and educational level are important for reporting aggression, with men and those with a secondary level of education more likely to report incidents.
