The effect sizes (Hedges’ g) with 95% CIs were estimated using a random-effects REML model. Pooled effects were: art (g = 0.79; 95% CI 0.56 to 1.03; Q(14) = 916.60; P < 0.001; I² = 99.14%), dance (g = 1.00; 95% CI 0.82 to 1.20; Q(5) = 13.86; P = 0.02; and I² = 0.00%), mixed (Mix) (g = 1.01; 95% CI 0.81 to 1.20; Q(10) = 20.58; P = 0.02; I² = 56.03%) and music (g = 0.63; 95% CI 0.61 to 0.65; Q(4) = 2.43; P = 0.66; I² = 0.04%). The overall pooled effect was significant (g = 0.83; 95% CI 0.70 to 0.95; Q(36) = 1,734.62, P < 0.001; I² = 98.25%). A significant subgroup difference was observed (Qb(3) = 271.36 and P < 0.001). All tests were two-sided with no adjustments for multiple comparisons.
