The Study of Mindfulness Based Cognitive Therapy and Obsessive-Compulsive Disorder

January 5, 2020 updated by: Shanghai Mental Health Center

The primary objective of the study is to evaluate the clinical curative effect of MBCT to reduce obsessive and compulsive symptoms. Moreover, the investigators will also explore a MBCT manual for Chinese patients with OCD, which can be widely applied to the clinical practice.

There are two parts of the study. The first part is a qualitative research with two pilot MBCT groups. The second part of this study is a single-blind randomized controlled trial with three study arms: one - third of participants receive group mindfulness-based cognitive therapy led by trained MBCT psychotherapists or psychiatrists in addition to medication, one - third of participants receive group psycho-education program and one - third of participants receive drug therapy as usual. All participants have 10 sessions intervention and assessments.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The qualitative research will use grounded theory path to interview therapists and patients for 60 minutes in the baseline, after 5 weeks treatments and after the 10 weeks treatments. The subjective experience of the therapists and patients in two pilot MBCT groups will be described and explained. And the entire process of treatments will be participatory observed.

In the second part of the study, all patients will take blood test and functional magnetic resonance imaging (fMRI) scan in the baseline and after 10 weeks, to gather data in genetics and imaging features, which can help the study to discover biological indicators of the curative effect. And after the patients and their custodians signed the consent form, all of participants will be blindly assigned to three groups by a predetermined random table which is generated by Microsoft Excel 2010 for ensuring randomly fair distribution across conditions. The investigators will not decode these numbers until the intervention group is assigned.

As the research tools, a range of self-rating scales, other-rating scales and behavioral and physiological measures will be mainly applied to assess clinical symptoms of participants at baseline (week 0), mid-treatment (week 4), at the end of acute treatment (week 10), and during the maintenance phase (week 14, 22 and 34).

After 10 sessions, all the participants including the non-responders and the responders (ie, decrease in Yale-Brown Obsessive Compulsive Scale [YBOCS] scores ≥ 25%) will enter the maintenance phase for 6 months. The participants in MBCT group will continue MBCT treatments at home. The participants in drug therapy group will continue on their treatment program without changing the type and dosage of medication they have been using. By comparing clinical symptoms, such as obsessive and compulsive symptoms, anxiety, depression, quality of life and other clinical symptoms and behavior, the study will describe the short-term and long-term effects of MBCT in patients with DSM-IV obsessive-compulsive disorder (OCD).

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Mindfulness-based Cognitive Therapy
MBCT group is a treatment group used mindfulness-based cognitive therapy, and guided by two therapists for 10 sessions. Every collection of about 6-8 patients is a closed structural group. Each session lasts 2.5 hours once a week, and has daily homework assignments.
Behavioral: Mindfulness-based Cognitive Therapy

The intervention will be carried out according to the handbook of the Dr. Didonna. There is a Session Agenda from Dr. Didonna for the use of the Instructor and session handouts for the participants. Some records of mindfulness practices will be given to participants for facilitating practice between sessions. Before each session, the instructor needs to review the session agenda and prepare copies of handouts for participants.

MBCT instructors were experienced psychotherapists and psychiatrists with several years' expertise in OCD treatment. They had been trained by one of the founders of MBCT, Mark Williams and the founder of MBCT for OCD, Fabrizio Didonna. Supervision will be provided by Dr.Didonna.
Placebo Comparator: Psycho-education Program
The program is consists of the information and principle of treatment for OCD, group sharing, supporting and discussion.
Behavioral: Psycho-education Program
As a widely used placebo control condition, the Psycho-Education Program can play an active role through the psychological suggestion and forward thinking mostly. It is designed to be similar with MBCT in level of structure, setting and other non-specific effects of psychological intervention. All instructors will be qualified graduate students who major in clinical psychology with training in cognitive behavioral therapy and psychodynamic therapy.
Active Comparator: SSRIs Therapy
This is a control group that can choose to use SSRI drugs which the SFDA approved for the treatment of OCD (Sertraline, Fluvoxamine, initial dose of 50 mg).
Drug: sertraline, fluvoxamine
The participants can be adjustable once a week dose and the maximum dose does not exceed the maximum amount of instructions. And benzodiazepine drugs also can be used by the OCD patients with sleep disorders, but not be used continuously for more than two weeks. Besides this, other psychotropic drugs are not allowed to use. The use of drugs in this study are commonly used drugs with good safety, and its common adverse reactions include dry mouth, constipation, nausea, indigestion, dizziness, fatigue, sweating and so on.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Yale-Brown Obsessive-Compulsive Scale
Time Frame: Change from baseline up to week 34
Yale-Brown Obsessive-Compulsive Scale is a medical semi-structured questionnaire with a total of 10 items that measure the severity of Obsessive thinking and compulsive behavior on a scale of 0 = None; 1 = Sub-threshold; 2 =Mild; 3 =Moderate; and 4 = Severe. The total score is to be got by adding every score of all the items. And the higher the score is, the more severe OC symptoms are.
Change from baseline up to week 34

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hamilton Anxiety Scale
Time Frame: Change from baseline up to week 34
Hamilton Anxiety Scale is the most common other-rating scale for clinical assessment of anxiety status and suitable for adults with anxiety symptoms. There are 14 items with each symptom rated on a five-point Scale.
Change from baseline up to week 34
Hamilton Depression Scale-24
Time Frame: Change from baseline up to week 34
Hamilton Depression Scale-24 is the most common other-rating scale for clinically assessing the state of depression and suitable for adults with depressive symptoms. There are 24 items rated to each symptom and most of the items used 0 to 4 points.
Change from baseline up to week 34
