1
Outcomes within each group and over time were determined by a mixed linear model for repeated measures using all available data at each time point. All means and Standard Errors (S.E) have been rounded to 2 decimal points.
2
Baseline values were not significantly different between groups (independent t tests P<0.05).
3
A significant group x time interaction effect denotes that the response over time differed between groups.
4
Scale values are 1–5 (where 1 = not at all confident and 5 = extremely confident and 4 or> = confident).
5
The combined confidence score is equal to the sum total of all other confidence scores (scores 20 or> = confident).
6
Times per week.
