EFA of the alcohol use and antisocial behavior items at each measurement occasion indicated that a single factor could reasonably be assumed for each set of alcohol use and antisocial behavior items at each time point. For alcohol use items, the ranges of fit indices of single factor models were [0.992, 0.996] for comparative fit index (CFI), [0.988, 0.995] for Tucker-Lewis index (TLI), and [0.036, 0.071] for root mean square error of approximation (RMSEA). For antisocial behavior items, the ranges of fit indices were [0.942, 0.992] for CFI, [0.935, 0.991] for TLI, and [0.016, 0.054] for RMSEA. In addition, from multiple-group CFAs at each measurement occasion, no significant differences were observed in the parameters of factor models between the subgroups of individuals with and without subsequent assessments (p-values of chi-squared difference tests were between 0.1281 and 0.6104), indicating that this assumption for the weighted least square estimator was not violated.
