^aT-score change = baseline − 3 months (thus, positive change score = improvement)

^bEffect size for within-group change = within-group change / SD of that group at baseline. Effect size for between-group change = difference in change scores / pooled SD of total sample at baseline

^cFeedback group T-score change − control group T-score change
