简要总结
The goal of this clinical trial is to learn if metacognitive therapy can be effective in a Chinese sample of obsessive compulsive disorder (OCD) . The main questions it aims to answer are:
Can metacognitive therapy significantly reduce participants' levels of obsessive-compulsive symptoms? Can metacognitive therapy significantly improve participants' metacognitive adaptations?
The researchers will compare metacognitive therapy to a control condition without psychotherapy to see if metacognitive therapy is effective in treating OCD.
Participants will:
Receive the metacognitive therapy intervention or under control conditions for 8 to 15 weeks.
Be assessed for symptoms and metacognitive beliefs at pre-intervention, post-intervention and 12 weeks post-intervention
详细描述
This study will be a randomised controlled clinical trial. Participants who meet the enrolment criteria will be randomised into an experimental group and a control group. Participants in the experimental group will receive 8-15 weeks of metacognitive therapy, while participants in the control group will receive the same amount of time of regular treatment without psychotherapy components.
The researchers will assess participants' obsessive-compulsive symptoms and metacognitive levels before, after, and 12 weeks after the intervention. Assessment measures will be the Yale Brown Obsessive-Compulsive Scale (Y-BOCS) and the Metacognition Questionnaire (MCQ-30).
By comparing the assessment results of the two groups of participants, conclusions will be drawn as to whether metacognitive therapy can have a positive effect on a Chinese OCD sample.
