Abstract：
BACKGROUND: Individuals with schizophrenia spectrum and related psychotic disorders (SSD) experience significant impairments in social cognition that impede functioning. Social cognition is a multidimensional construct consisting of four domains: 1. theory of mind, 2. emotion processing, 3. attributional style and 4. social perception. Metacognitive training (MCT) is an intervention designed to target cognitive biases in psychosis containing two modules addressing social cognition.
METHODS: A systematic review and meta-analysis was conducted to investigate the effects of MCT on social cognition and two of its domains: theory of mind and emotion processing. Ten electronic databases were scoured from 2007 to 1 February 2022 for MCT studies reporting social cognition outcomes for people with SSD (1050 identified, 282 assessed). Effect sizes were calculated using Cohen\'s d in R.
RESULTS: Nine studies were included in the meta-analysis (nMCT = 212, ncontrol = 194). MCT had a small but positive effect on global social cognition (d = 0.28 [95% CI 0.07-0.49]) and theory of mind (d = 0.27 [95% CI 0.01-0.52]). MCT showed no evidence of an effect on emotion processing (d = 0.03 [95% CI -0.26 to 0.32]).
CONCLUSIONS: MCT has a small but significant effect on social cognition for people with SSD. Our results add to other recent meta-analyses showing significant effects of MCT on clinically relevant outcomes such as positive symptoms, cognitive biases and cognitive insight. We recommend that future studies on MCT report outcomes on all four domains of social cognition.

摘要：
背景：患有精神分裂症谱和相关精神病（SSD）的个体在社会认知方面经历了严重的损害，从而阻碍了功能。社会认知是由四个领域组成的多维结构:1.心理理论，2.情绪处理，3.归因风格和4。社会认知。元认知训练（MCT）是一种干预措施，旨在针对精神病中的认知偏见，其中包含两个解决社会认知的模块。
方法：进行了系统综述和荟萃分析，以研究MCT对社会认知及其两个领域的影响：心理理论和情绪加工。从2007年到2022年2月1日，对十个电子数据库进行了搜索，用于MCT研究，报告了SSD患者的社会认知结果（1050确定，282评估）。使用R.中的Cohen'sd计算效应大小。
结果：9项研究纳入荟萃分析（nMCT=212，ncontrol=194）。MCT对整体社会认知（d=0.28[95％CI0.07-0.49]）和心理理论（d=0.27[95％CI0.01-0.52]）有很小但积极的影响。MCT没有显示对情绪处理有影响的证据(d=0.03[95%CI-0.26至0.32])。
结论：MCT对SSD患者的社会认知有微小但显著的影响。我们的结果添加到其他最近的荟萃分析中，显示MCT对临床相关结果的显着影响，例如阳性症状，认知偏见和认知洞察力。我们建议未来对MCT的研究报告社会认知的所有四个领域的结果。
