• Abstract: Suicide has emerged as a leading cause of death among university students in China. Due to its profoundly adverse impact, suicide prevention has consistently been a critical priority in university mental health initiatives. The recently proposed “Three-Step Theory of Suicide” (3ST) provides a clear framework for the dynamic process through which suicidal ideation progresses into suicidal behavior. It shifts the focus of research and practice from “which factors are associated with suicidal behavior” to “how these factors contribute to the behavior.” This theory suggests that universities should move away from a static, solution-oriented model and instead establish a dynamic, process-oriented intervention system to systematically enhance the effectiveness of suicide prevention. 自杀已经成为我国高校危及大学生生命安全的最大的“杀手”。鉴于自杀事件的极端恶劣影响，自杀的预防工作历来是高校心理卫生重点工作。作为新生的“从想法到行动”自杀三步理论清晰地展示了从自杀意念到自杀行为的过程，将关注点从“哪些影响因素与自杀行为有关”转变为“这些影响因素如何对自杀行为起作用”，这一理论启示高校预防和干预自杀要放弃以解决方案为导向，转向以过程为导向，进而提高自杀预防能力。
