Childhood maltreatment and its associations with trauma-related psychopathology: disentangling two classification approaches.

Childhood maltreatment (CM) is associated with various mental health disorders, including PTSD, depression, and anxiety. This study explores how specific classifications - dichotomous (abuse versus neglect) and dimensional (physical, emotional, sexual) - relate to distinct psychopathologies. We recruited 642 individuals, screening them for CM history and symptoms. ANOVA, regression, and SEM analyses compared CM approaches and symptom associations. The dichotomous approach showed significant effects of abuse and neglect on all symptoms. In the dimensional approach, sexual and physical CM were primary features for PTSD, while sexual and emotional CM were primary for depression and anxiety. Overall, the dimensional approach outperformed the dichotomous approach in capturing symptoms, suggesting its importance in understanding psychopathologies and guiding therapeutic interventions. Our findings highlight the differential associations of CM experiences with PTSD, depression, and anxiety symptoms. The findings suggest the importance of a dimensional CM approach for understanding psychopathologies and possibly informing targeted therapeutic interventions.
