Aim: To evaluate the efficacy of the Portuguese version of the metacognitive training (MCT) programme for schizophrenia and its effects on psychotic symptoms, insight into the disorder and functionality.
Design: This is a randomized controlled trial that will be undertaken in six psychiatric institutions in Portugal.
Methods: This study was approved in March 2019. The sample will consist of people with schizophrenia. The evaluation instruments will include sociodemographic and clinical questionnaires, the Psychotic Symptom Rating Scales, the Beck Cognitive Insight Scale, the World Health Disability Assessment Schedule, and the Personal and Social Performance Scale, applied to both groups at three different times. In the experimental group, the eight MCT modules will be applied over 4 weeks.
Discussion: It is expected that at the end of the programme, the experimental group will have reduced severity of psychotic symptoms and improved insight into the disease and functionality.
Impact: Schizophrenia is a severe mental disorder that, in most cases, leads to the deterioration of cognitive and social functioning as a result of psychotic symptoms. Metacognitive training for schizophrenia has been used in several countries, but its efficacy remains unclear. It is a type of programme that consists of changing the cognitive infrastructure of delusions.
目的: 评估葡萄牙版本的元认知训练(MCT)计划对精神分裂症的疗效及其对精神病症状、认知障碍及功能的影响。 设计: 这是一项随机对照试验,试验将会在葡萄牙的六家精神病院进行。 方法: 该研究于2019年3月获得批准。试验样本将由精神分裂症患者组成。评估工具将包括社会人口统计学和临床问卷、精神病症状评定量表、贝克认知洞察力量表、世界健康残疾评估表以及个人和社会表现量表,分别在三个不同的时间应用于两组。试验小组将在4周内进行八个元认知训练(MCT)模块。 讨论: 预计在项目结束时,实验组将降低精神病症状的严重程度,并提高对疾病及功能的认识。 影响: 精神分裂症是一种严重的精神障碍,大多数情况下,精神病症状会导致认知和社会功能的恶化。精神分裂症的元认知训练已经在几个国家使用,但其效果尚不清楚。这是一个改变错觉认知基础结构的项目。.
