| Objective To explore the mediating effect of rumination on the relationship between insomnia and suicidal ideation in adolescents with depressive disorder， so as to provide guidance for the preventions of suicidal ideation.Methods A total of 302 adolescents with major depressive disorder in Department of Psychosomatic Medicine of Deyang People's Hospital from January to December 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5） clinical significance criterion for depressive disorder were enrolled. All individuals were assessed using Insomnia Severity Index （ISI）， Ruminative Response Scale （RRS） and Positive and Negative Suicide Ideation （PANSI）. Then the mediating effect of rumination in the relation between insomnia and suicidal ideation in adolescents with major depression disorder was analyzed using Process v3.2 model 4， and testified with the bias-corrected non-parametric percentile Bootstrap method.Results ISI scores in adolescents with major depression disorder were positively correlated with PANSI score （r=0.400， P<0.01）， and were positively correlated with RRS total score， obsessive thinking and introspection factor score （r=0.378， 0.360， 0.333， P<0.01）. RRS score was also positively correlated with PANSI score （r=0.292， P<0.01）. Rumination exerted a partial mediating effect on the relationship between insomnia and suicidal ideation （β=0.174， 95% CI： 0.098~0.261）.Conclusion The relationship between insomnia and suicidal ideation in adolescents with depressive disorder is partially mediated by rumination， additionally， insomnia can affect suicidal ideation in adolescents with depressive disorder both directly and indirectly through rumination. |
