The regression model was run twice with difference dummy code for intervention type. Change Across Negative Intervention represents the intercept when the positive intervention is coded as Pos = 1 and represents mean change in each DV across the negative intervention (when variables are standardized). Change Across Positive Intervention is the intercept when Pos = 0, and the Difference Between Intervention Conditions is the standardized regression coefficient that represents the effect of intervention condition (i.e., the difference between negative and positive conditions). ^*Represents significance after Bonferroni correction. DV = dependent variable.
