家庭功能不良与青少年内感受及情绪和躯体症状关系及其性别差异OACHSSCD

Objective:To explore the relationship between adverse childhood experiences(ACEs),interocep-tion,and emotional and somatic symptoms in adolescents,and to examine the mediating role of interoception and its sex differences.Methods:A total of 629 vocational school students(age 14-24)were assessed using the ACE-IQ(including family dysfunction),MAIA-2(interoceptive sensitivity),GAD-7(anxiety),PHQ-9(depression),and PHQ-15(somatic symptoms).Results:After controlling for confounders,only family dysfunction among ACEs showed significant sex differences in prevalence,with a higher rate in females.Females reported higher levels of GAD-7,PHQ-9,and PHQ-15 than males(P＜0.001)and lower total interoception scores(P＜0.05),particularly in"non-distraction"dimension and so on.Mediation analysis revealed that,among females,the"non-distraction"di-mension of interoception partially or fully mediated the relationship between family dysfunction and the scores of GAD-7(β=0.10;21.8%of total effect),PHQ-9(β=0.11;24.4%),and PHQ-15(β=0.11;30.4%).In males,the mediating effect of interoception was not significant.Conclusion:Family dysfunction is a key risk factor for ad-olescents'emotional and somatic symptoms.The"non-distraction"aspect of interoception plays a significant media-ting role in females.
