Scores are medians (ranges). Scores range from 0 to 100. Values are mean differences between week 1 and week 6, with 95% confidence intervals and p-values for from t-tests, testing if the change is zero, with Signed Rank tests also being performed as some distributions were slightly skewed. Differences are calculated as week 6 minus week 1, so positive values indicate larger values are week 6 and negative values indicate smaller values are week 6 compared to week 1.

Performance is a reverse-scored item. Higher performance values represent greater perceived success.
