Abstract:
Objective:To explore the relationship between rumination and depression and suicide attempts, and the mediating effect of rumination between depression and suicide attempts in adolescents with depressive disorder.Methods:Clinical interviews and questionnaires were conducted on 331 adolescents aged 11-18 with depressive disorders.Depressive symptoms were assessed with patient health questionnaire-9 (PHQ-9). Rumination was assessed with ruminative responses scale-10 (RRS-10), and Chinese version of the sociality module of MINI5.0 was used to assess suicide.SPSS 23.0 software was applied to descriptive statistics, Chi-square test, t-test, Spearman correlation analysis and hierarchical regression analysis, and the SPSS macro program PROCESS V 3.4 was used for Bootstrap mediating effect. Results:The incidence of suicide attempts in adolescents with depressive disorder was 53.78%, which was significantly higher in girls (59.48%) than that in boys (40.40%), and the difference was significant ( χ2=10.16, P<0.01). In contrast to the non-suicide attempt group, suicide attempt group had higher scores on PHQ-9((11.08±9.26) vs (14.43±7.49), t=-3.634, P<0.01), brooding ((10.76±3.89) vs (12.44±3.87), t=-3.926, P<0.01), reflection ((10.05±3.54) vs (11.20±3.33), t=-3.044, P<0.01) and rumination total score ((20.81±6.78) vs (23.64±6.42), t=-3.898, P<0.01). Regression analysis revealed that girl ( β=0.175, t=3.228, P=0.001), depressive symptoms ( β=0.168, t=3.082, P=0.002), rumination ( β=0.138, t=2.364, P=0.019) were risk factors for suicide attempts.Rumination played a complete mediating effect between depressive symptoms and suicide attempts (effect value=0.013, 95% CI=0.003-0.027). Depression symptoms significantly and positively predicted rumination ( P<0.01), and rumination significantly and positively predicted suicide attempts ( P<0.05). Conclusion:The incidence of suicide attempts was high in adolescents with depressive disorders.Depressive symptoms affect suicide attempts mainly through rumination.Clinicians should assess the rumination of adolescents with depressive disorders.In addition, clinicians should implement concurrent psychotherapy to adjust the cognitive response and reduce rumination, in order to improve the mental health and reduce suicide attempts.
