摘要
自杀倾向是自杀过程中的重要组成部分,指的是个体有体验自杀行为的动机和趋势,由于某种原因打算自杀或准备实施自杀的一种心理活动。生命愿景是一种精神化的应对源,强调对生命的认知和对生存的动机,主要有生命控制感、消极或积极的生命意义及对生命意义的追求三个主要内容。大学生自杀一直是社会关注的主要健康问题,本研究以自杀倾向大学生为研究对象,探讨其压力感、生命愿景及自杀倾向间的关系。以《自杀倾向综合调查问卷》对全国13所高校的1000名大学生进行施测,筛选出具有自杀倾向的大学生154名,其中男生78名,女生76名,以《大学生心理压力感问卷》和《生命愿景量表》为研究材料进行问卷调查。研究结果表明:(1)女生的压力感水平(t=3.45,p<0.01)、自杀倾向水平(t=3.49,p<0.01)显著高于男生,而在生命控制感上低于男生(t=-2.25,p<0.05);(2)压力感与自杀倾向呈显著的正相关(r=0.45,p<0.01),生命愿景与压力感和自杀倾向呈显著的负相关(r=-0.34,-0.53;ps<0.01)(;3)压力感可以直接预测自杀倾向水平(Bate=0.45,t=6.15,p<0.01),也可以通过间接的作用于生命愿景,进而影响自杀倾向,生命愿景的中介效应占总效应的32.52%,进一步对生命愿景的各维度的分析发现,除了意义的追寻,生命控制感、消极生命意义、积极生命意义都起到中介作用,中介效应分别为43.00%,10.31%,6.08%。这些结果说明在有自杀倾向的大学生中,生命愿景在压力感对自杀倾向的影响中起到中介作用,相对于生命愿景的其他维度的中介作用,生命控制是更重要的中介变量。
Suicidal inclination is an important part of suicide, refers to the individual have motivations and trends to experience suicidal behavior, which is a kind of mental activity for preparing to commit suicide for some reason. Life Vision is a spiritual response to the source, emphasizing cognition of life and motivation for survival, which mainly contain sense of life control, meaning of life(positive or negative), as well as pursuing life meaning. College students' suicide has been the major health issue of social concern, the relationships among stress feeling, life vision and suicidal inclination were explored in 154 college students with suicidal inclination who screened from 1000 college students of 13 universities by "suicidal inclination's comprehensive questionnaire", including 78 boys, 76 girls. The main results showed:(1) girls' level of stress feeling(t = 3.45, p < 0.01), suicidal inclination(t = 3.49, p < 0.01) was significantly higher than boys'. But lower in sense of life control(t =-2.25, p < 0.05);(2) Stress feeling and suicidal inclination showed a significant positive correlation(r = 0.45, p <0.01), but life vision existence significance negative correlation with both stress feeling(r =-0.34, p < 0.01) and suicidal inclination(r =-0.53, p < 0.01);(3) Stress feeling can directly predict suicidal inclination(Bate = 0.45, t = 6.15, p < 0.00), which can also be an indirect effect on the life vision, thereby affecting suicidal inclination, the mediating effect was 32.52%. Further analysis with each dimension of life vision found that, in addition to pursuing life meaning, sense of life control, negative and positive meaning of life had significantly paly an mediation role, mediating effect were 43.00%, 10.31%, 6.08%. These results indicate that in suicidal inclination's college students, life vision as the mediator between the processes of stress feeling affecting suicidal inclination, compared to other dimensions of life vision, sense of life control is the more important mediator.
