Notes: ¹ N ranged between 59–62; ² N for follow up was 17 (range 15–17); ³ Likert scale values from 1 to 7: 1 = never, 2 = less than once a week, 3 = once a week, 4 = 2–4 times a week, 5 = 5–6 times a week, 7 = more than once a day; ⁴ P25, 25th percentile, P75, 75th percentile; * p-value significance accepted at p < 0.05 using post hoc Wilcoxon Signed-Rank Test.
