Abstract: Abstract Suicide is defined as an individual’s spontaneous thoughts and behaviors aimed at ending their own life, including suicidal ideation and suicide attempts. The demographic differences and potential mechanisms underlying suicidal ideation and attempts remain unclear and warrant further investigation. A total of 5,408 college students (mean age = 20.06 years, 23.85% male) from South China completed a psychological screening questionnaire. Based on Klonsky’s Ideation-to-Action Framework and O’Connor’s Integrated Motivational-Volitional Model, we established two chain mediation models to explore the complex relationships among stressful life events, rumination, psychotic symptoms, and suicidal issues while investigating the demographic differences in suicidal ideation and attempts. The findings indicate that various demographic factors are associated with suicidal ideation and attempts. Among these, a history of mental illness and somatic symptoms are significant common risk factors. Additionally, the results reveal that rumination and psychotic symptoms serve as chain mediators in the relationship between stressful life events and both suicidal ideation and attempts. This study not only examines the impact of fundamental demographic variables on suicidal ideation and attempts from the perspective of demographic influencing factors but also discusses and compares the important mediating roles of rumination and psychotic symptoms in the relationship between stressful life events and suicide issues.
