Baseline: N = 569 (387 intervention, 182 comparison). T2: n = 338 (212 intervention, 126 comparison). T3: n = 311 (196 intervention, 115 comparison). Stress (score ranged 1–4): the higher the score, the less stress. Depressive symptoms (score ranged 0–60): the lower the score, the fewer depressive symptoms. Positive affect (score ranged 1–4): the higher the score, the more positive affect. Negative affect (score ranged 1–4): the higher the score, the less negative affect. *p < 0.05, **p ≤ 0.01 for comparisons between the intervention and comparison groups within a timeframe. #p < 0.05 for comparisons between T2 and T3 within the comparison group
