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.
ABSTRACT
Objective To understand the characteristics of problem behaviors among junior middle school students in northern Guizhou rural areas to provide reference for formulating the intervention measures .Methods The Chinese middle school students mental health scale and the self-made externalizing behavior problem questionnaire were adopted to perform the questionnaire sur-vey on left-behind kids of 6 junior middle schools .Results In the implicit problem behavior ,the scores of girls in hostility ,interper-sonal ,depression factor ,anxiety and total score were higher than those of boys ,and the each factor score was increased with grade ;in the explicit behavioral problems ,the occurrence rates of smoking ,drinking and gambling in boys were higher ,the detection rates of smoking and gambling were higher than those in students ,the occurrence rates of suicidal idea and leaving from home idea in students were 13 .1% and 22 .2% respectively ,in which the occurance rates of girls were higher than those in boys .The detection rate of sex related behaviors in boys was higher than that in girls .Conclusion The problem behaviors appear the gender and grade differences among left-behind kids in northern Guizhou rural areas .The differential mental health education should be carried out according to different target behaviors .
