The homogeneity models, which constrain the parameter estimates to be equal across the sexes, did not fit significantly worse than the heterogeneity models, which allow the parameter estimates to vary across the sexes. However, the patterns of results from the homogeneity and heterogeneity models were substantively different for physical maltreatment and neglect, indicating the possibility there was insufficient power to differentiate between the homogeneity and heterogeneity models. Therefore, results from both the homogeneity and heterogeneity models were interpreted for these variables.
