N = 514 for Model Set 1: Head Injury Count; N = 246 for Model Set 2: LOC Count; *p < 0.05, **p < 0.01, ***p < 0.001. Race/ethnicity was coded White = 1 and Other racial/ethnic identities = 0. Education was coded High school diploma/GED or greater = 1 and Less than high school = 0. Unemployed was coded 1 = Unemployed and 0 = Employed either part-time or full-time. Rural/urban was coded 1 = Rural residence and 0 = Urban residence. Physical and Sexual IPV severity were calculated as weighted sums based on prior experiences. Dependent variables were symptom severity scores, based on summed severity ratings for items aligning with each symptom domain.
IPV, intimate partner violence; LOC, loss of consciousness.
