Four structural models predicting pretreatment performance (measured in September and October) plus treatment to posttreatment near- and far-transfer outcomes (measured in March). The Full (base) Model is the least parsimonious structural, in which each of the six dimensions of pretreatment performance plus treatment was included as a predictor of outcomes. Each of the subsequent (nested) models is more parsimonious. In the Cognitive Model, pretreatment cognitive dimensions and treatment were examined as the sole predictors of outcomes. In the Math Model, pretreatment calculations and word-problem skill and treatment were considered as the sole predictors of outcomes. In the DA Model, pretreatment DA and treatment were examined as the sole predictors of outcomes.
