The Effect of Impulsivity Traits on Senior High School Students’ Suicidal Ideation: The Role of Campus Exclusion and Sense of Life Meaning

Abstract

Abstract: In order to examine whether campus exclusion mediated the relationship between impulsivity trait and suicidal ideation, and whether this mediating effect was moderated by sense of life meaning, the present study was conducted by 633 senior school students in Liaoning province with adopting four anonymous questionnaires, namely Barratt Impulsiveness Scale, Campus Exclusion Inventory for Adolescents, Meaning in Life Questionnaire, and Suicide Ideation Scale. The results demonstrated that: 1) Impulsivity trait positively predicted to suicidal ideation among high school students. 2) Campus exclusion played a partial mediating role in the association of impulsivity trait and suicidal ideation among high school students. 3) The mediating effect of impulsivity trait on high school students’ suicidal ideation was moderated by sense of life meaning. Specifically, with the increase of the sense of life meaning, the effect of campus exclusion on suicidal ideation gradually weakened. These results suggest that impulsivity trait can facilitate the intensity of high school students’ suicidal ideation through campus exclusion, and the sense of life meaning can effectively buffer the negative impact of campus exclusion on suicidal ideation.

Key words: impulsivity trait, suicidal ideation, campus exclusion, sense of life meaning, senior high school students

摘要： 采用冲动性特质量表、青少年遭受校园排斥问卷、生命意义感量表、自杀意念量表对633名高中生进行调查。结果表明：（1）冲动性特质对高中生自杀意念有显著的正向预测作用；（2）校园排斥在冲动性特质与高中生自杀意念间起部分中介作用；（3）冲动性特质经由校园排斥影响高中生自杀意念的中介作用受生命意义感的调节，随着生命意义感的增加，校园排斥对自杀意念的效应逐步减弱。冲动性特质可以通过校园排斥增加高中生自杀意念强度，而生命意义感能有效降低校园排斥对自杀意念的消极影响。
