[i] Note. CI = 95% confidence interval. Time span between pre- and posttest and all two-way and three-way interactions with the predictors (condition, time, and transportation) were included in the model but are not displayed to enhance readability of the table. Categorical variables were effect-coded (Time: pretest = –1, posttest = 1, follow-up = 1; Condition: documentary = –1, fictional TV series = 1). Continuous predictors (transportation, time between pre- and posttest) were mean-centered. A square-root transformation was applied to time between pre- and posttest because the data were positively skewed.
