Adverse childhood experiences, symptoms of anxiety and depression in adulthood: Mediation role of life history strategy.

Life history theory has considered the effects of childhood experiences. The present study aimed to investigate the mediating role of life history strategy and the moderating role of gender in the relationship between childhood experiences and symptoms of anxiety and depression in adulthood. In this study, 248 Iranians (including 162 females and 86 males) between 18 and 53 voluntarily participated and responded to all online questionnaires regarding the COVID-19 pandemic. The data were analyzed with SPSS and macro PROCESS. The mediation analysis results demonstrated that the life history strategy mediates the relationship between childhood experiences and symptoms of anxiety and depression. The moderated mediation analysis revealed that there were no gender differences in the moderated mediation. The results have highlighted the importance of life history strategies in the association between childhood experiences and depression and anxiety symptoms and can be considered in the design of interventions based on the prevention of people's vulnerability to mental disorders.
