Methods 1505 college students were investigated with ASLEC, Simplified Coping Style Questionnaire, SSRS, QSA and BDI. Results Incidence rate of college students' suicidal ideations during the past year was 6.67%. The goodness of fit for the structural equation model was satisfactory and 3 major indices( x2/df = 2.23, GFI = 0. 982, RMSEA = 0. 029 ) had met corresponding requirements. The depression was directly influencing factor on suicide ideation, while four factors including passive coping style, social support, positive coping style and suicide attitude, had indirect impacts.
