After five classes, the model did not converge. Thus, more than six class-solutions fit really poorly. Model selection was performed before we compared with groping variables (e.g., gender and lifetime interparental violence). That is, these fit statistics refer to an unconstrained model with respect to gender and lifetime interparental violence in LCA
