The measurement models for aggressive behavior and peer victimization were constructed from parcels of items created using the domain representative approach (Little et al. 2002), such that each parcel included items from each of the subscales of the relevant measures. The aggression model was created from four parcels (factor loadings of .83–.88) and fit the data quite well, χ2(1)=1.13, p=.324, CFI=1.00, and RMSEA=0.01 (90% CI: 0.00–0.06). The peer victimization model was also created from four parcels, each including items reflecting each of the three types of victimization (factor loadings of .75–.87). This model was an excellent fit to the data, χ2(2)=2.21, p=.332, CFI=1.00, and RMSEA=0.01 (90% CI: 0.00–0.06).
