The long-term effects of childhood stressors, such as childhood abuse and inappropriate parenting experiences, on adult depression are mediated by personality traits. In the present study, we hypothesized that parental bonding in childhood influences adulthood depression, and that this association is mediated by childhood victimization experiences and negative life event evaluations in adulthood. To test this hypothesis, multiple regression analysis and structural equation modeling were performed.Methods: A questionnaire survey, including Patient Health Questionnaire-9, victimization scale in childhood, Parental Bonding Instrument (PBI), and Life Experiences Survey was administered to 449 general adult volunteers (age: 41.1 ± 11.7 years; 196 men and 253 women). Multiple variables were analyzed by multiple regression analysis and structural equation modeling.Results: Multiple regression analysis demonstrated that victimization experiences in childhood affect adulthood depression independently of several other factors. Structural equation modeling showed that the “parental care” subscale of the PBI decreased adulthood depression directly, as well as indirectly through its effects on victimization experiences in childhood and negative life events. On the other hand, the “parental overprotection” subscale of the PBI increased adulthood depression directly, as well as indirectly through its effects on the experience of victimization in childhood and negative life events.Conclusion: The present study indicates that the experience of victimization in childhood is a risk factor of adulthood depression. Furthermore, we found that parenting quality experienced in childhood influences adulthood depression, and that these effects are mediated by the experiences of victimization in childhood and negative life events in adulthood.Keywords: victimization, parental bonding, negative life event appraisal, depression, structural equation modeling
