Abstract:
Objective:To explore the relationship between childhood abuse, pleasure experience, sleep quality and self-injury behavior in adolescents with depressive disorder.Methods:One hundred and twenty adolescent patients with depressive disorder hospitalized in the Fourth People's Hospital of Hefei City from January 2021 to February 2024 were selected as the study group, as well as 120 healthy controls matched with the patients' age, gender and education level were selected as the control group.The adolescent non-suicidal self-injury assessment questionnaire, Pittsburgh sleep quality index, temporal experience of pleasure scale, and childhood trauma questionnaire were used for assessment. Statistical analysis was performed using SPSS 26.0 software. Independent sample t-test was used for comparison between the two groups. Pearson correlation analysis was used to analyze correlations between scale scores. Chain mediating modeling was used with the PROCESS macro program. Results:The differences of the study group and the control group in childhood abuse ((53.33±15.21), (39.07±11.81), t=8.081, P<0.001), pleasure experience ((85.60±15.77), (67.44±19.46), t=7.941, P<0.001), self-injury behavior ((29.01±9.89), (3.76±0.49), t=8.811, P<0.001), sleep quality ((12.24±4.15), (6.56±4.05), t=10.711, P<0.001), and depression ((30.62±7.97), (5.88±3.28), t=31.451, P<0.001) were all statistically significant. The self-injury behavior of the study group was positively correlated with the sleep quality ( r=0.487, P<0.001) and childhood abuse ( r=0.553, P<0.001), and negatively correlated with the pleasure experience ( r=-0.483, P<0.001). Childhood abuse had a negative predictive effect on pleasure experience ( β=-0.491, P<0.001), there was a positive predictive effect of childhood abuse on sleep quality ( β=0.363, P<0.001), there was a negative predictive effect of pleasure experience on sleep quality ( β=-0.321, P<0.001), there was a simultaneous predictive effect of childhood abuse, pleasure experience and sleep quality on self-injury behaviors predictive effect ( β=0.343, P<0.001, β=-0.211, P<0.001, β=0.208, P<0.001).The total effect of childhood abuse on self-injury behavior mediated by pleasure experience and sleep quality was 0.555(95% CI=0.448-0.663), and the direct effect was 0.343(95% CI=0.219-0.468).The mediating effect of pleasure experience between childhood abuse and self-injury behavior was 0.104(95% CI=0.007-0.196), accounting for 18.74% of the total effect, the mediating effect of sleep quality between childhood abuse and self-injury behavior was 0.075(95% CI=0.028-0.133), accounting for 13.51% of the total effect, and the chain mediating effect of pleasure experience and sleep quality between childhood abuse and self-injury behavior was 0.033(95% CI=0.011-0.060), accounting for 5.95% of the total effect. Conclusion:Sleep quality and pleasure experience exert the chain mediating effect between the childhood abuse and self-injury behavior in adolescents with depressive disorders.
