Visceral Sensitivity Index-C: Psychometric Validation Data for Chinese DGBI Patients

102 patients with disorders of gut-brain interaction (DGBI) completed questionnaires for the validation of the Chinese Visceral Sensitivity Index (VSI-C). Mingyu Fu published this validation study data on figshare in April 2026. The dataset likely contains patient scores from the VSI-C, Hospital Anxiety and Depression Scale, and Patient Health Questionnaire-15.

Use Cases

• Validate psychometric instruments for gastrointestinal-specific anxiety based on the described factor analysis and reliability testing.
• Assess correlations between anxiety, depression, and somatic symptoms in DGBI patients based on the described use of HADS and PHQ-15.
• Establish clinical cutoff scores for screening tools based on the described receiver operating characteristic curve analysis.
• Study cultural adaptation of medical questionnaires based on the described translation and validation process.

Strengths

• Psychometric validation includes multiple metrics: Cronbach's α of 0.861 and Spearman-Brown coefficient of 0.860 indicate good reliability.
• Content validity was assessed by an expert panel with a scale-level content validity index average of 0.91.
• Structural validity was confirmed through exploratory factor analysis, confirmatory factor analysis, and exploratory graph analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (23.7 KB), indicating limited scope and sample size.
