Effectiveness of Traditional Chinese Metacognitive Training (MCT) in Patients With Schizophrenia, Depression, or Bipolar Disorder Attending a Psychiatric Day Hospital in Taiwan

Rövid összefoglaló (regiszter, angolul)

Schizophrenia is characterized by positive symptoms such as delusions and hallucinations, which significantly impact daily functioning. While antipsychotics are the primary treatment, many patients exhibit resistance or intolerance. Metacognitive Training (MCT) has shown promise in addressing cognitive biases related to positive symptoms, offering potential benefits as an adjunct to pharmacological treatment. Additionally, cognitive biases are prevalent in other psychiatric disorders, such as bipolar disorder and major depression, and are closely related to the onset and persistence of emotional symptoms. Preliminary studies have supported the effectiveness of MCT in reducing depressive symptoms and related biases. However, its effects in Taiwan remain unexplored. Therefore, this study aims to examine the effectiveness of the Traditional Chinese version of MCT for individuals with schizophrenia in Taiwan. This study adopts a one-group pretest-posttest design, recruiting 26 participants to undergo an 8-session MCT group intervention over four weeks. Assessments include the Chinese versions of the Psychotic Symptom Rating Scales (C-PSYRATS), the Traditional Chinese version of the PROMIS Depression and Anxiety Short Forms (4a v1.0), the Modified Davos Assessment of Cognitive Biases Scale (MCL-DACOBS), the Self-reported Graphic Personal and Social Performance Scale (SRG-PSP), Self-Reported Activities of Daily Living Scale, third version (sf-ADLS), and Neuro-QoL Item Bank v2.0 - Cognitive Function- Short Form. Participant satisfaction is also collected. Statistical analyses will utilize non-parametric Wilcoxon Signed-Rank Test and Cohen's d for effect size calculations. Despite limitations such as a single-group design and recruitment from one hospital, this study is the first to examine MCT's applicability in Taiwanese clinical settings. Expected outcomes include improvements in positive symptoms, depressive and anxiety symptoms, cognitive biases, cognitive functioning, daily living skills, and social functioning. Future research should validate these findings through randomized controlled trials across multiple sites.
