Ten items adapted from two empirically validated scales (Straus, 1979, 1990; Wyatt, 1985) were used to assess physical and sexual abuse, and witnessing parental/domestic violence before age 18. Scales of these items have excellent reliability [intraclass coefficients, 0.79–0.88 (Ruan et al. 2008)]. A three-factor model with a latent dimension indexing each IPV type provided an excellent fit to the data [Comparative Fit Index (CFI (Bentler, 1990)]: 0.96, Tucker-Lewis Index [TLI (Tucker & Lewis, 1973)]: 0.89, RMSEA (Root Mean Square Error of Approximation): 0.05).
