DOI:10.1080/00223891.2017.1339711The cohen’s d’s were not calculated correctly in the descriptive statistics for Study 1 – the effect sizes in the paper are double what they should be.
On Page 3, the cohen’s d’s in the following paragraph should read as follows:
We performed Bonferroni-corrected pairwise t tests to examine differences in composite scores between the four factors. Of all the factors, the down-regulation of anger (D-ANG) had the highest score, D-ANG and U-POS, t(489) d = 11.27, p < .001, d = .51; D-ANG and D-DES, t(489) = 5.00, p < .001, d = .23, although it did not differ significantly from D-POS. Similarly, down-regulation of positive emotions scores (D-POS) and down-regulation of despondency or distress (D-DES) scores did not differ significantly from one another, but both scores were significantly higher than the up-regulation of positive emotions (U-POS), D-POS and U-POS, t(489) = 8.14, p < .001, d = .37; D-POS and D-DES, t(489) = 7.62, p < .001, d = .35. These results suggest that people believe that they are better at down-regulating than up-regulating their emotions, and believe they are best at down-regulating their anger.
The authors apologize for their oversight.
