Investigation into the effects of the software, MCT, for the improvement of cognitive function in people with schizophrenia

本研究旨在探讨元认知训练（MCT； S. Moritz et al., 2010）对精神分裂症患者（以下简称患者）的影响。MCT是一个使用PowerPoint图像的群体认知行为治疗项目。在本研究中，MCT每周进行一次（约60分钟），共8次。在每次MCT前后分别获得自我参照量表、新控制源量表和负反刍量表3份问卷的答案。研究对象为住院患者15例（男9例，女9例）。通过统计比较MCT实施前后的答案，我们发现消极反刍量表存在显著差异。这些结果表明，MCT可能会加强认知，使患者不会反复出现不愉快的想法。

The aim of this study was to investigate the effects of metacognitive training (MCT; S. Moritz et al., 2010)in people with schizophrenia (hereinafter, patients).MCT is a program for group cognitive behavioral therapy that uses PowerPoint images. In the present study, MCT was performed once a week (approximately 60 min) for a total of 8 sessions.Before and after each MCT session, answers to 3 scales were obtained(self-reference, new locus of control scale, and negative rumination scale).Subjects were 15 hospitalized patients 6 men,9 women).On statistically comparing answers before and after implementation of MCT,we found significant differences in the negative rumination scale.These results suggest that MCT may strengthen cognition so that patients do not repeatedly have unpleasant thoughts.
