Fig 3
To analyze the perception of time, the apparent time value reported on the questionnaire was subtracted from the actual time value given (actual time—apparent time = perception of time). Positive value: perception of ACT shorter. Negative value: perception of ACT longer. Values above 0: participants felt they spent less time taking the ACT routine than the actual time they spent to taking it. Values below 0: participants felt they spent more time taking the ACT routine than the actual time they spent taking it. Differences were calculated at baseline and the final interviews. The data are presented as the mean (± SD). Wilcoxon test was performed to compare the differences between the baseline and final measures in each group. Changes: *p = 0.003 (Treated Group); p = 0.076 (Placebo Group); p = 0.857 (Control Group).
