An Exploratory Study on the Prediction of Recurrence Risk of Bipolar Disorder Using Sentiment Analysis Technology Based on Multi-modal Feature Fusion

May 1, 2026 updated by: Jun CHEN, Shanghai Mental Health Center
Bipolar disorder (BD) has become a significant public health problem with complex clinical manifestations, difficult treatment, and poor prognosis. However, there is still a lack of effective biological markers for diagnosing and predicting recurrence. Sentiment analysis computing usually refers to using machine equipment to classify, identify, interpret, and imitate human emotions. However, current multi-modal emotion analysis research is mainly based on one or two modalities. Due to the diversity and complexity of patients' emotional expressions, this single- and dual-modal information analysis is far from enough for accurate discrimination of emotional symptoms. Only emotion analysis technology based on multi-modal feature fusion can make more precise and effective judgments. The current project is based on our previous research on cognitive neuroimaging and big data analysis of bipolar disorder. The investigators plan to enroll 200 BD patients who meet DSM-5 diagnostic criteria and 200 healthy controls. The investigators will use sentiment analysis technology with multi-modal feature fusion (text data, audio and visual modalities, eye movements, and electrophysiology) to identify BD recurrence. Biological markers for risk prediction and an algorithm model for joint judgment of multi-source information will be established to analyze the characterization data. The effectiveness of this recurrence prediction model will be further verified and optimized through a large-sample, prospective cohort study design. It is hoped that it can provide a new method for predicting the recurrence risk of BD patients. In the near future, clinical decision-making aids based on this auxiliary method can be developed, and the translational application value of clinical diagnosis and treatment can be explored.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

1. patients with bipolar disorder; 2. healthy controls.

Description

Patients group inclusion criteria:

  • Patients who have previously met or currently meet the diagnostic criteria for bipolar disorder according to DSM-5, whose condition and treatment are currently stable, and who cooperate with the assessment;
  • Age ≥18 years, <65 years;
  • Han Chinese ethnicity;
  • Sufficient visual and auditory abilities to complete the necessary examinations for the study;
  • Understanding the study content and signing the informed consent form. If the patient is unable to sign the informed consent form personally due to low education level or other reasons, it may be signed by a relative or guardian on their behalf.

exclusion criteria:

  • The presence of intellectual disability or other conditions that significantly affect the patient's current mental state;
  • the patient has a serious or unstable physical illness, including: neurological disorders (delirium, dementia, stroke, epilepsy, migraine, etc.), congestive heart failure, angina pectoris, myocardial infarction, arrhythmia, hypertension (including untreated or uncontrolled hypertension), malignant tumors, immunodeficiency, and blood glucose levels higher than 12 mmol/L; or other diseases that may interfere with the test assessment (abnormal indicators more than twice the normal value).

Healthy controls group inclusion criteria:

  • Age ≥ 18 years, < 65 years;
  • Han Chinese ethnicity;
  • Gender matched to the patient group;
  • Sufficient visual and auditory ability to complete the necessary examinations for the study;
  • Understanding of the study content and signing of informed consent;
  • No family history of mental illness. exclusion criteria:
  • Individuals with a mental disorder conforming to DSM-5, or those with suspicious mental symptoms but not meeting the diagnostic criteria;
  • Individuals with severe physical illness that makes it difficult to complete the necessary examinations.

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
The recurrence status of patients with bipolar disorder
Time Frame: 1 year, patients will be followed-up every 3 months and healthy controls will be assessed only at baseline
The presence and the type of a relapse will be diagnosed by psychiatrists and assessed using DSM-5 by study assistants. Furthermore, predictive models for recurrence risk of bipolar disorder will be constructed, with adopting the Area Under Curve (AUC) of Receiver Operating Characteristic (ROC) and other measurements to evaluate the performance of constructed models.
1 year, patients will be followed-up every 3 months and healthy controls will be assessed only at baseline
