Abstract: ObjectiveTo investigate the suicide attitudes of college students and analyze the impact of the perception of life
purpose and meaning of life on their suicide attitudes using structural equation modeling.MethodsA total of1050college
students were tested by Suicide Attitude Questionnaire (QSA), Purpose in Life test (PIL) and Chinese version of Meaning of
Life questionnaire (C-MLQ). A theoretical model was established for confirming the influence of the purpose in life and
meaning in life on suicide attitudes of the college students.ResultsThe college students had generally a negative attitude
towards suicide. The female students tended to show more objective attitudes towards suicide and the students from rural
areas had a stronger attitude against euthanasia.The meanings and purposes in life were closely correlated with the attitudes
towardssuicide, andthestructuralequationmodelingwellfittedthedata(χ²/df=1.924, GFI=0.936, AGFI=0.915, NFI=0.937, CFI=
0.940, and RMSEA=0.045). The perception of meaning and purposes in life had a direct predictive value on the suicide attitude
of the college students, and the presumptions derived from the theoretical model were strongly supported by structural
equation modeling.ConclusionThe perceptions in meanings in life and purposes in livelihood have important influence on
the suicide attitudes of college students, and intervention with effective life education should be administered to guide the
suicide attitude of the college students.
