Based on the current increase in levels of citizen violence, it is relevant to standardize instruments for identifying crime-related risk factors in youth population. Therefore, this work aims to analyze the psychometric properties of Plutchik’s Violence Risk Scale (PVRS). The PVRS Spanish version was linguistically adapted to local terminology, and subsequently examined by eight judges. It was administered to 1052 university students from Lima, who ranged from 16 to 37 years old. The exploratory factor analysis showed a single-factor structure, which differs from the three-factor Spanish version. It was applied the Rasch model of Andrich’s Rating Scale because of its unidimensionality, identifying sex differential functioning of three items. Reliability was obtained through coefficient omega, whose value was .70; 95% CI [.63, .77]. In conclusion, the PVRS has suitable psychometric properties and appears to be a good alternative to screen the risk of violence in populations similar to the one studied.
