Note: SCT, Social Cognition Training.

^aIn 7 studies, Cognitive Remediation Therapy (CRT) was used as a control group. Since it is an active form of treatment that does not explicitly target social cognition, it was classified as an active control group. To investigate a potential treatment effect of CRT, we added the use of CRT as a variable to the moderator analyses.

^bWe defined targeted treatments as those targeting 1 or 2 domains of social cognition, as there were several treatments (eg, training of affect recognition⁸) that predominantly targeted a single domain, but also included some training of a second domain, and therefore were not as comprehensive as many of the treatments classified as “broad-based.”
