Abstract
This article explores the definition and main characteristics of severe violent crimes committed by minors, and provides an in-depth analysis of Carl Jung's analytical psychology and the biopsychosocial model of interaction. These theoretical frameworks offer crucial perspectives for understanding the complex psychological motivations and social environmental impacts behind juvenile criminal behavior. Based on this, the paper proposes a multidimensional prevention strategy that includes psychological education, enhanced community support, and optimization of the family environment, aimed at preventing juvenile crime and promoting their healthy development.
