^aAdjusted for the depression subscale score of DASS 21 (≥ 10 or < 10) in the baseline survey.

^bMixed-models for repeated measures ANOVA model analyses were conducted.

^cMixed-models for repeated measures conditional growth model analyses were conducted.

^dEffect sizes were calculated by dividing the estimated effect by a pooled SD at baseline and at follow-ups.
