Abstract:
Objective:To explore the effects of non-suicidal self-injury on suicidal ideation in adolescents with depressive disorder, and the mediating role of rumination and depression between them.Methods:A sample of 397 depressive disorder adolescents were recruited to complete the adolescent non-suicidal self-injury behaviour questionnaire, ruminative responses scale (RRS), self-rating depression scale (SDS), and Beck scale for suicide ideation-Chinese version(BSI-CV). All data processing and analysis were performed using SPSS 23.0.The mediating effect was tested by correlation analysis and Bootstrap analysis.Results:The non-suicidal self-injury score was (29.192±11.281), the rumination score was (65.036±12.284), the depression score was (75.770±11.278), and the suicidal ideation score was (40.681±11.626). Non-suicidal self-injury was significantly and positively correlated with suicidal ideation( r=0.403, P<0.01), rumination and depression( r=0.332, 0.470, both P<0.01). Rumination was significantly and positively correlated with depression and suicidal ideation( r=0.549, 0.181, both P<0.05). Depression was significantly and positively correlated with suicidal ideation( r=0.313, P<0.01). The direct effect value of non-suicidal self-injury on suicidal ideation was 0.341(95% CI=0.238-0.444), the indirect effect of non-suicidal self-injury on suicidal ideation through two pathways, the separate mediating effect value of depression was 0.057(95% CI=0.077-0.114), and the chain mediating effect value of rumination and depression was 0.026(95% CI=0.004-0.057). Conclusion:Non-suicidal self-injury can directly affect suicidal ideation of depressive disorder adolescents and indirectly through rumination and depression.
