This is a toy dataset containing pre-calculated effect size data of a meta-analysis on randomized controlled trials comparing the effectiveness of 'third-wave' CBT interventions for perceived stress in college students to inactive controls. Effect size data is provided as the standardized mean difference (SMD) between the intervention and control group and the corresponding standard error for each study at post. The dataset also contains columns for study characteristics which may serve as potential effect size moderators.
