Cohort Study of Obsessive-Compulsive Disorder

10 września 2026 zaktualizowane przez: Qing ZHAO, Shanghai Mental Health Center
This study will establish a standardized, multi-dimensional prospective longitudinal cohort for obsessive-compulsive disorder. It seeks to explore differences in symptom trajectories, functional trajectories, treatment responses, and long-term outcomes among different OCD clinical subgroups. Additionally, it will examine whether multi-modal measures (including clinical features, neuropsychological tests, neuroimaging, electroencephalography (EEG), magnetoencephalography (MEG), functional near-infrared spectroscopy (fNIRS), and blood and stool biospecimens) can explain clinical heterogeneity and predict treatment response and long-term prognosis.

Obsessive-Compulsive Disorder Participants
This is a prospective, observational, longitudinal disease-specific cohort study for obsessive-compulsive disorder. This cohort contains first-episode obsessive-compulsive disorder, initial-treatment non-responders, and pharmacotherapy-resistant obsessive-compulsive disorder.No additional research-based randomization will be performed, and no therapeutic interventions will be assigned by investigators. After completing baseline assessments, participants with obsessive-compulsive disorder will enter longitudinal follow-up. After the first-year follow-up, participants will be followed-up every six-months for a total follow-up duration of 5 years. Collected data encompass clinical information and rating scales, biospecimens (blood, stool), neuropsychological tests, MRI, electroencephalography, functional near-infrared spectroscopy (fNIRS), eye-movement tests, and magnetoencephalography. Participants are permitted to enroll in optional nested sub-studies.

Change from baseline in Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) total score
Ramy czasowe: Baseline, 8-week, 12-week, 6-month, 9-month, 12-month, every 6-months thereafter up to total 5-year follow-up
This scale was developed by Goodman et al. It is a widely used self-assessment tool for obsessive-compulsive symptoms both domestically and internationally, consisting of 10 items and 42 sub-items. The scale employs a 5-point rating system ranging from 0 to 4. The total score ranges from 0 to 40. The higher the score, the more severe the obsessive-compulsive symptoms. A total score of 8-15 indicates mild obsessive-compulsive symptoms, 16-25 indicates moderate symptoms, and a score above 25 indicates severe symptoms. Its Chinese version was introduced and validated for reliability and validity by our research group, and has been extensively adopted in both clinical practice and research settings. In the present study, Y-BOCS scores will be applied for participant screening at enrollment, and will also serve as an assessment tool for symptom severity during follow-up visits.

Ramy czasowe: Baseline, 8-week, 12-week, 6-month, 9-month, 12-month, every 6-months thereafter up to total 5-year follow-up
This scale was revised by Beck et al. and is a self-assessment tool used to evaluate the degree of depression. It consists of 21 items and is used to assess the severity of depressive symptoms. This scale uses a four-point rating system from 0 to 3. The total score ranges from 0 to 13 indicating no depression, 14 to 19 indicating mild depression, 20 to 28 indicating moderate depression, and 29 to 63 indicating severe depression.

Change from baseline in Beck Anxiety Inventory (BAI) total score
Ramy czasowe: Baseline, 8-week, 12-week, 6-month, 9-month, 12-month, every 6-months thereafter up to total 5-year follow-up
This scale was developed by Beck et al. It consists of 21 items, each of which is rated on a scale of 0 to 3, representing four levels. It is a self-assessment tool for evaluating anxiety symptoms. The total score is the sum of all items, with a score range of 0 to 63. The higher the score, the more severe the anxiety. A total score of 15-25 indicates mild anxiety, 26-35 indicates moderate anxiety, and above 36 indicates severe anxiety. The Chinese version of this scale has good reliability and validity and is widely used in the assessment of anxiety symptoms.

Number of participants experiencing any adverse event identified via participant follow-up interview

Adverse events prospectively captured during follow-up are documented, includes adverse events that may occur during the actual phamachotherapy treatment process of the research participants, as well as during psychological treatment or other intervention studies. During the research, the occurrence time, manifestation form, severity, handling measures, and outcome of the adverse events will be recorded.Each participant is counted once if one or more adverse events newly occur after study enrolment, regardless of total event episodes. Data will be summarized using participant counts and corresponding proportions.
From study baseline until the end of study follow-up (variable follow-up duration across participants)
Number of participants with suicidal-related events assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS)

Number of participants experiencing serious adverse events identified via participant follow-up interview
Ramy czasowe: From study baseline until the end of study follow-up (variable follow-up duration across participants)
Serious adverse events are defined according to ICH-GCP criteria. Events are documented using verbatim clinical descriptions obtained from study follow-up interviews.
