Note: Twelve analyses were conducted, each with two predictors: the main effect of condition and the interaction effect of condition by child externalizing. A false discovery rate methodology was applied to guard against Type I error, reflected in the adjusted α column. The main effects are presented in the top half of the table and the interaction effects are presented in the bottom half of the table. Increases in the variable are denoted by (+) and decreases in the variable are denoted by (−) in response to the challenge.
