Note. Maternal report variables include mother’s report of her own BMI category, whether she is trying to lose weight, her frequency of dieting, her weight dissatisfaction, and whether she encourages her child to diet to lose weight. Adolescent Report variables include adolescents’ report of mothers’ weight status, mothers’ dieting frequency, and whether mother encourages the adolescent to diet to lose weight. Adj R2 = adjusted R2, which is adjusted for the number of predictors in the model. Base model includes covariates (adolescent weight status, race/ethnicity, socioeconomic status, and cohort) and baseline level of the dependent variable. Maternal report model is base model with the addition of mother report variables (see text for description of models). Adolescent report model is base model with the addition of adolescent report variables. Full model is base model with the addition of all maternal and adolescent report variables.
aF and p values are for the test of the increment in R2 gained by adding the predictors to the model.
bMaternal report and adolescent report blocks are mutually adjusted.
