1
Outcomes at each time point 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
Scale values are 1–5 (where 1 = not at all confident and 5 = extremely confident).
3
The combined confidence score is equal to the sum total of all other confidence scores (scores 20 or> = confident).
4
Times per week.
