“…Eight studies (Cho et al, 2016; Jiang et al, 2016; Kang et al, 2009; Prokopenko et al, 2013; Prokopenko et al, 2018; Van De Ven, Murre, et al, 2017; Xiao, 2018; Yoo et al, 2015) reported the effects of CCT on ADL, and four studies (De Luca et al, 2018; Prokopenko et al, 2013; Prokopenko et al, 2018; Van De Ven, Murre, et al, 2017) reported the effects of CCT on depression. The meta‐analysis showed that there was no significant difference in ADL (SMD = 0.14, 95%CI = −0.07 to 0.34, P = 0.19) and depression (SMD = −0.07, 95%CI = −0.39 to 0.25, P = 0.68) between two groups with low heterogeneity ( I 2 = 25% and 35% respectively) (Figures 7 and 8).…”
