Moritz et al.'s metacognitive training (MCT), a new development of cognitive therapy, is a manualized group training program, designed to correct cognitive biases involved in the formation and maintenance of psychotic symptoms, especially delusions. We report on the efficacy of MCT in a Chilean sample of people with schizophrenia.
50 outpatients from the Hospital Del Salvador at Valparaíso, Chile, were randomly assigned to the intervention group (MCT), or the control group, that only received treatment as usual (TAU). Subjects were assessed at the beginning and end of the study with the Positive and Negative Syndrome Scale (PANSS), Cognitive Biases Questionnaire for Psychosis (CBQ-P) and Beck Cognitive Insight Scale (BCIS).
In the MCT group, we found larger, statistically significant improvements, in symptoms, cognitive biases and cognitive insight, than in the control group. However, after a direct comparison of both groups, only the improvement in psychotic symptoms for the MCT group, remained significantly different.
The results of this study suggest superiority of MCT over TAU in the amelioration of positive symptoms. We could not, however demonstrate its superiority in the improvement of the cognitive biases and cognitive insight.
莫里茨等人的元认知训练（MCT）是认知疗法的一项新进展，是一种手册化的团体训练项目，旨在纠正与精神病症状尤其是妄想的形成和维持相关的认知偏差。我们报告了MCT在智利精神分裂症患者样本中的疗效。
来自智利瓦尔帕莱索萨尔瓦多医院的50名门诊患者被随机分配到干预组（MCT）或仅接受常规治疗（TAU）的对照组。在研究开始和结束时，用阳性和阴性症状量表（PANSS）、精神病认知偏差问卷（CBQ-P）和贝克认知领悟量表（BCIS）对受试者进行评估。
在MCT组中，我们发现与对照组相比，在症状、认知偏差和认知领悟方面有更大的、具有统计学意义的改善。然而，在对两组进行直接比较后，只有MCT组的精神病症状改善仍有显著差异。
本研究结果表明，MCT在改善阳性症状方面优于TAU。然而，我们无法证明其在改善认知偏差和认知领悟方面的优越性。
