Abstract:
Objective:To explore the effects of anhedonia, childhood abuse, and depression on suicidal ideation, and the mediating role of anhedonia in adolescents.Methods:A total of 7 431 middle school students were invited to participate in the study. Suicidal ideation, depression, childhood abuse, and anhedonia were assessed by the Positive and Negative Suicide Ideation Scale (PANSI), Self-Rating Depression Scale (SDS), Childhood Trauma Questionnaire (CTQ) and Temporal Experience of Pleasure Scale (TEPS); according to the score of suicidal ideation, a total score of 36 was used as the cut-off score, all students were divided into the group with suicidal ideation ( n=1 265) and the group without suicidal ideation ( n=6 166). Difference test was performed using independent sample t-test and χ 2 test; Correlation analysis was performed by Pearson correlation; The process macro program compiled by Hayes was used to conduct the regulated mediation model analysis; The mediation effect values and 95%bootstrap confidence intervals of depressive symptoms between childhood maltreatment and suicidal ideation were analyzed by the bootstrap method; Simple slope analysis was utilized to examine the interaction effects for depression and anhedonia. Results:The detection rate of adolescent suicidal ideation was 17.02% (1 265/7 431);Childhood abuse significantly positively predicted depression ( β=0.56, P<0.001); depression significantly positively predicted suicidal ideation ( β=0.59, P<0.001); depression and anhedonia interaction significantly predicted suicidal ideation ( β=-0.05, P<0.001); simple slope analysis indicates that low anhedonia depression predicted suicidal ideation ( β=0.51, P<0.001) than the high anhedonia group ( β=0.47, P<0.001). Conclusion:Depression partially mediates the effects of childhood abuse on suicidal ideation, and anhedonia modulates the effects of childhood abuse on suicidal ideation. As the level of anhedonia gradually increases, the predictive effect of depression on suicidal ideation gradually decreases.
