Fifteen studies comparing effects on positive symptoms, delusions or acceptance with control group were included this meta-analysis. These comprised total 408 patients condition and 399 condition. moderating masking outcome assessment, randomization, incomplete data, use an active intervention, individual vs investigated. Possible sensitivity analyses publication bias also examined. results show significant overall effect symptoms (g = -0.34, 95% CI [-0.53, -0.15]), -0.41, [-0.74, -0.07]) -0.84, [-1.37, -0.31]). Using only being at low risk regarding data reduced sizes -0.28, [-0.50, -0.06] g -0.18, [-0.43, 0.06]), respectively. This demonstrates that exerts small to moderate large intervention. reduced, but remains when potential biases are considered.
