Childhood maltreatment is a key predictor of mental health problems across the life span. Yet, how maltreatment types independently and jointly influence the risk for psychiatric problems remains unclear. The aim of the study was two-fold: first, to replicate recent findings regarding the impact of maltreatment types on youth psychiatric symptoms, based on a Brazilian sample of high-risk adolescents (n = 347; age range = 11-17 yrs), and second, to extend existing findings by examining whether this relationship is mediated by bullying victimization and/or perpetration. Measures included self-report ratings of childhood maltreatment and peer victimization, as well as multi-informant reports of internalizing and externalizing symptoms. Consistent with prior research, we found that: (i) maltreatment types often co-occurred; (ii) there was a linear association between number of maltreatment types experienced and symptom severity (i.e. cumulative effect); and (iii) emotional abuse emerged as the most consistent independent predictor of poor mental health across domains, raters, and gender. Additionally, this study extends previous findings by showing that the influence of maltreatment on psychiatric outcomes is partially mediated by peer victimization, but not by bullying perpetration. In conclusion, these findings expand our understanding of the heterogeneity in individual responses to maltreatment as well as highlighting emotional abuse as an important predictor of poor mental health.

Objective: To evaluate the interrelationships between childhood maltreatment, life satisfaction (LS), and depressive symptoms, and to investigate LS as a mediating factor in the association between childhood maltreatment and depressive symptoms. Methods: The sample consisted of 342 adolescents, aged 11 to 17 years (mean = 13.3, SD = 1.52 years), recruited from a public school in Salvador, Brazil. Participants filled out instruments for the collection of sociodemographic data and evaluation of childhood maltreatment, LS, and depressive symptoms. Structural equation modeling (SEM) was used to evaluate the mediating effect of LS. Results: We detected significant negative correlations between childhood maltreatment and LS and between LS and depressive symptoms. We observed a significant positive correlation between childhood maltreatment and depressive symptoms. LS partially mediated the association between childhood maltreatment and depressive symptoms, mitigating the impact of maltreatment. Conclusion: LS played an important mediating role in the association between childhood maltreatment and depressive symptoms. Longitudinal studies are recommended to fully elucidate these associations, reinforcing the need for attention and care of this vulnerable population.
