Abstract:
Objective:To investigate the psychological characteristics of self-injurious behavior (SIB) among Chinese adolescents with depression and the chain mediation mechanism of emotional-behavioral difficulties.Methods:A total of 214 hospitalized adolescents with depression (158 SIB, 56 non-SIB) were assessed using the Rosenberg self-esteem scale (SES), Barratt impulsiveness scale-11 (BIS-11), self-rating depression scale (SDS), and strength and difficulty questionnaire (SDQ) from March 2022 to January 2024. Permutation test, ridge regression, and Bootstrap chain mediation models were applied to identify predictors and pathways by R 4.4.1 software.Results:The SIB group exhibited significantly lower self-esteem (21.6±4.9 vs 24.8±6.4, F=14.9, P<0.01) compared with the non-SIB group.The scores of impulsivity (68.1±8.9 vs 63.2±10.6), depression (33.0±6.2 vs 27.5±7.6), and emotional-behavioral difficulties (21.5±5.8 vs 17.4±7.5) in the SIB group were significantly higher than those in the non-SIB group( F=11.5, 29.0, 17.9, all P<0.01). Ridge regression identified depression ( β=0.137, P<0.001) as the core predictor. Chain mediation analysis revealed that the direct effect of emotional-behavioral difficulties on SIB was not significant ( β=0.004, 95% CI=-0.011-0.018).Emotional-behavioral difficulties affected self-injurions behavior indirectly through the mediating effects of functional impairment and depression, as well as their chain mediating effect, with a total indirect effect of 0.015 (95% CI=0.006-0.026). Conclusion:SIB is driven by the chain mechanism linking emotional-behavioral difficulties, functional impairment, and depression, necessitating integrated interventions targeting emotional regulation and functional recovery.
