Bonferroni post hoc tests indicated significant differences among all groups on all dimensions, with the exception of Motives—Social which was only significant in the comparison of 6–29 days versus 30 days (P = 0.02) and Motives—Self-confidence which was only significant in the comparison of 1–5 days versus 30 days (P = 0.001).
