ABSTRACT

Objective:To investigate the relationship between childhood psychological abuse and dark triad with suicide ideation, and to provide references for suicide prevention in college students.Methods:A total of 2 995 college students from 6 universities including Guangxi, Sichuan, Henan, Guizhou and Chongqing were enrolled, and were investigated with the child psychological maltreatment scale (CPMS), dirty dozen(DD), and suicide ideation questionnaire.SPSS 26.0 software was used for correlation analysis and macro program-PROCESS was used to analyze the mediating effect.Results:The prevalence of childhood psychological maltreatment among college students was 29.32%, which in male students and students with left-behind experience (33.38%, 34.60%) were higher than that in female students and students without left-behind experience (25.65%, 25.98%)(χ 2=21.53, 25.47, both P<0.01) respectively.There was positive correlation between childhood psychological maltreatment, dark triad and suicidal ideation( r=0.32-0.41, all P<0.001). Dark triad had a partial mediating effect between childhood psychological maltreatment and suicidal ideation(effect size=0.08, 95% CI=0.06-0.10). An analysis of multiple mediating effects on the three dimensions of dark triad found that Machiavellianism and psychopathy had significant mediating effects between childhood psychological maltreatment and suicidal ideation(effect size=0.05, 95% CI=0.02-0.07; effect size=0.07, 95% CI=0.04-0.10), while narcissism had no significant mediating effect(effect size=-0.01, 95% CI=-0.01-0.01). Conclusion:Childhood psychological maltreatment can not only directly affect the suicide ideation of college students, but also further affect the suicide ideation through dark triad.
