to load onto a (positive) Family Functioning LV. These LVs were allowed to correlate with the Time 1 MTI factors and also served as predictors of the Time 2 MTI factors, along with the Time 1 MTI factors. Standard SEM approaches were used for determining parameter significance. (Note that the MTI item invariance constraints were also employed for this final model). The sample N for the MTI model analyses was 315 (those participants with MTI items at both Time 1 and Time 2). For the final model, which included the two external correlate LVs, the sample N was 252. There were no significant differences between those with versus without the externalizing or family functioning variables in terms of the MTI variables and similarly for age or education (results available on request).
