Introduction and AimsEarly childhood is crucial for the development of social and emotional competencies, significantly influenced by parental interactions. While the impact of maternal psychopathology has been extensively studied, less is known about the effect of paternal trauma on parenting behaviors and subsequent child development. This study examines the effects of fathers' traumatic experiences on their psychopathology, quality of feeding interactions, and children's emotional and behavioral functioning. MethodsA sample of 100 fathers and their two-year-old children participated in this cross-sectional study. Paternal psychopathology was assessed using the Symptom Checklist-90-Revised (SCL-90-R), and trauma exposure was measured with the Traumatic Experience Checklist (TEC). Parent-child feeding interactions were evaluated using the Scala di Valutazione delle Interazioni Alimentari (SVIA), and children's emotional and behavioral outcomes were assessed using the Child Behavior Checklist (CBCL 1,5-5). ResultsFathers with past trauma displayed significantly higher levels of psychopathological symptoms and engaged in poorer quality feeding interactions compared to controls. These paternal characteristics were associated with higher scores on maladaptive outcomes in children's CBCL, indicating worse emotional and behavioral functioning. ConclusionsThe findings suggest that paternal trauma is linked to increased psychopathological risks and negatively affects the quality of paternal feeding interactions, which in turnith children's emotional and behavioral development. These results underscore the importance of integrating paternal trauma into clinical assessments and interventions to support family dynamics and promote healthier developmental outcomes in children.
