Abstract

Background

The category Fluency Test (CFT) is included in the MATRICS consensus cognitive battery for schizophrenia (MCCB). This test has several components that allow the exploration of other cognitive functions and could be related to different symptom profiles.

Methods

a sample of 98 Mexican adolescents was evaluated with the CFT and the following components were analyzed: total words, errors, clusters, switching, related words, and categories. Demographic and clinical differences among them and correlations with other MCCB tests and with Positive and Negative Syndrome Scale (PANSS) factors were explored.

Results

The CFT components showed significant correlations with each other and with other MCCB tests, particularly with those related to verbal learning, working memory, and speed of processing. In addition, they showed moderate correlations with the total PANSS score and with the negative, positive, and cognitive PANSS factors.

Conclusions

The analysis of CFT components allows clinicians and investigators to obtain information regarding other cognitive functions and symptom profiles in adolescents with schizophrenia.

青少年精神分裂症的类别流畅性测试成分及其与认知和症状的关系

背景类别流畅性测试(CFT)包含在精神分裂症(MCCB)的matrix共识认知电池中。该测试有几个组成部分，允许探索其他认知功能，并可能与不同的症状概况有关。方法采用CFT量表对98名墨西哥青少年进行测评，并对总字数、错误字数、聚类、转换字数、相关字数和类别进行分析。探讨两组患者的人口学和临床差异，以及与其他MCCB检测结果和阳性阴性综合征量表(PANSS)因素的相关性。结果CFT各组成部分之间以及与其他MCCB测试之间均存在显著的相关性，尤其是与语言学习、工作记忆和加工速度相关的部分。此外，它们与PANSS总分以及消极、积极和认知PANSS因素表现出中度相关性。结论CFT成分的分析使临床医生和研究人员能够获得有关精神分裂症青少年其他认知功能和症状概况的信息。
