To explore the mediating role of self-hating in the influence of adverse childhood experiences on adolescents' negative emotions.

A questionnaire method was used to collect demographic variables, and 7 012 valid questionnaires were obtained from adolescents by applying the revised adverse childhood experiences questionnaire, patient health questionnaire-4, and self-hate scale from May 1 to May 30, 2022, in five high schools(90 classes) and five junior high schools(60 classes) in Rizhao city, Shandong province, China. Data entry and analysis were performed by SPSS 22.0 software.Mann-Whitney U test was used for the comparison between demographic variables and other variables, and the correlations between variables were expressed by Spearman correlation coefficient. AMOS 23.0 software was applied for testing the mediating and moderating effects of variables.

(1)There were significant positive correlations between adverse childhood experiences(0(2)) and negative emotion(3(10))(r=0.459, P<0.01), self-hating(2(4))(r=0.427, P<0.01). There were significant positive correlations between self-hating and negative emotion(r=0.566, P<0.01). (2) Self-hating played a mediating role between adverse childhood experience and adolescent negative emotion, and the mediating effect was 0.299, accounted for 61.27% of the total effect.(3) The mediating pathway of self-hated was moderated by gender, with girls' adverse childhood experiences(B_simple=2.428, t=39.585, P<0.05) predicting self-hating more than boys(B_simple=1.641, t=25.355, P<0.05).

Adverse childhood experiences can predict adolescents' negative emotions, and self-disgusting can also affect adolescents' negative emotions.Gender plays a moderating role in the mediating pathway.
