RCT Entities:   Population Interventions Outcomes

There is an error in the second sentence under the heading “Results” in the Abstract. The correct sentence is: The intervention group showed a statistically significant improvement (ES d = 0.45, p = .01) in the All items domain of the rating scales between t1 and t2 and showed a significant advantage compared with the CG (ES d = .41, p = .04).

In Table 7, the values in the column with the heading “Effect Size” are incorrect. Please see the corrected Table 7 here.
