	Interpersonal Trauma Exposure Group
	Not Exposed to Maltreatment or Partner Violence Against Mother		Exposed to Maltreatment or Partner Violence Against Mother		Exposed to Maltreatment and Partner Violence Against Mother
	M	SD	M	SD	M	SD
Sociodemographic risk	1.69	1.63	2.83	1.83	3.27	1.42
Developmental competence
Preschool	0.59	3.75	−1.09	3.33	−0.74	4.14
School-age	0.30	1.01	−0.62	0.74	−0.40	0.72
PTSD symptoms	0.54	0.96	1.28	0.99	1.96	0.85

Note. Exposure to any trauma (maltreatment, partner violence) was associated with greater sociodemographic risk, lower preschool and school-age competence, and greater PTSD symptoms than exposure to no trauma (ps < .01). Exposure to both trauma types (maltreatment and partner violence) was associated with greater PTSD symptoms than exposure to one type (p = .038).
