医学院学生自杀意念与希望特质、抑郁情绪的关系以及希望特质的调节作用

目的:探讨医学院学生的自杀意念与希望特质和抑郁情绪的关系,以及在其中希望特质的调节作用。方法:选择某医学院各年级学生按比例进行分层整群随机抽样调查,发放自杀意念自评量表(SIOSS)、希望特质量表(DHS)和抑郁自评量表(SDS)。回收有效问卷148份。结果:样本中自杀意念检出率为8.1%,其中有自杀意念组抑郁得分高于无自杀意念组(t=8.699,P0.001),希望特质评分低于无自杀意念组(t=-6.077,P0.001);抑郁得分与自杀意念得分成正相关(t=0.681,P0.01),希望特质得分与自杀意念得分成负相关(t=-0.328,P0.01)。并且分层回归显示,抑郁自评量表得分与希望特质的交互作用显著(t=-4.727,P0.01),即希望特质在抑郁情绪与自杀意念之间有显著的调节作用。结论:自杀意念与抑郁情绪消极相关,与希望特质积极相关。关注大学生抑郁情绪,提高大学生希望特质水平,可以增强危机因素的抵抗作用,有助于对大学生自杀危机干预工作提供科学参考。

The Mediating Effect of Dis-positional Hope between Suicidal Ideation and Depression Emotion in Medical College Students

Objective:To explore the relationship among suicidal ideation ,dis-positional hope and depression emo‐tion in medical college students ,especially ,the mediating effect of dis-positional hope .Methods:Surveying the medi‐cal students collected by cluster randomized sampling method and distributing questionnaire as Self -rating Idea of Suicide Scale(SIOSS) ,Dis -positional Hope Scale(DHS) ,and Self -rating Depression Scale(SDS) .at last ,there were 148 effective questionnaire .Results:8 1.% students had suicidal idea ,the score of SDS was higher in students with suicidal idea(t=8 6.99 ,P<0 0.01)and the score of DHS was higher in students without suicidal idea(t=‐6 0.77 , P<0 0.01) .We also found positive correlation between the score of depression and the score of suicidal ideation(r=0 6.81 ,P<0 0.1) ,and negative correlation between the score of dis-positional hope and suicidal ideation .(r=‐0 3.28 , P<0 0.1) .And hierarchical regression analysis showed that the score of SDS and SIOSS had significantly interactive effects I.t meant that the dis-positional hope acted as a significant moderator between depression emotion and sui‐cidal ideation .Conclusion:There are negative correlation between dis-positional hope and suicidal ideation ,but posi‐tive correlation between depression and suicidal ideation S.o we should pay attention to depressive emotion of college students ,and enhance theirs hope dis-positional as protective effect to mental healthy crisis .The survey aims to pro‐vide a scientific reference for college students suicide crisis intervention work .
