Trial Outcomes & Findings for Exploring the Effect of Rumination-Focused Cognitive Behaviour Therapy in Patients With Schizophrenia (NCT NCT04442893)

NCT ID: NCT04442893

Last Updated: 2023-11-09

Results Overview

The Beck Depression Inventory-II (BDI-II) is a 21-item self-report depression screening measure. Each item is rated on a four-point Likert-type scale ranging from 0 to 3, which with possible scores ranging from 0 to 63. The BDI-II has been translated into a Chinese version. Higher total scores indicate more severe depressive symptoms, and a score of \>16 points is considered suggestive of the presence of clinically significant depressive symptom intensity. In this study, the investigators will explore the change of BDI-II score among baseline, after intervention and three-month follow-up.

Measure
Experimental Group
The experimental group would be provided with a 6- session RFCBT program for 12 weeks (60-90 mins, once every two weeks). Rumination-Focused Cognitive Behaviour Therapy: Rumination-Focused Cognitive Behavioural Therapy(RFCBT) is based on a differentiation between functional and dysfunctional styles of perseverative thinking with the helpful style characterized as a concrete, process-focused and specific style of thinking and the idea that rumination is a habit maintained by negative reinforcement. In line with the theoretical assumptions, RFCBT combines strategies from behavioral activation with strategies to foster concrete, process-focused and specific thinking.
Control Group
The control group would receive a 6- session Health Education program for 12 weeks (60-90 mins, once every two weeks) Health Education programme: Health education programme would be any planned activity or set of activities aimed at increasing health literacy and developing life skills conducing to health (e.g. decision making, problem solving, critical thinking, interpersonal skills, stress management, coping with emotions).

The Chinese Response Style Questionnaire-short form revised (CRSQ-10) is a self-report measure of rumination, comprising ten items and describing the factors of brooding and reflection. Each item is rated on a four-point Likert-type scale ranging from 1 (strongly disagree) to 4 (strongly agree), which with possible scores ranging from 10 to 40. The CRSQ-10 has been used to evaluate the intensity of ruminative responses to depressed mood. In this study, the investigators will explore the change of CRSQ-10 score among baseline, after intervention and three-month follow-up.

The Internalized Stigma of Mental Illness (ISMI) Scale is a 29-item self-report questionnaire measuring self-stigma among persons with psychiatric disorders. Each item is rated on a four-point Likert scale from 1 (strongly disagree) to 4 (strongly agree), which with possible scores ranging from 29 to 116. The ISMI Scale has been translated into a Chinese version. Higher scores indicating greater self-stigma. In this study, the investigators will explore the change of ISMI Scale score among baseline, after intervention and three-month follow-up.
