ObjectiveThe visceral sensitivity index (VSI) is a useful self-report measure of the gastrointestinal symptom-specific anxiety (GSA) of patients with irritable bowel syndrome (IBS). Previous research has shown that worsening GSA in IBS patients is related to the severity of GI symptoms, suggesting that GSA is an important endpoint for intervention.
However, there is currently no Japanese version of the VSI. We therefore translated the VSI into Japanese (VSI-J) and verified its reliability and validity.
Material and methodsParticipants were 349 university students aged 18 and 19 years and recruited from an academic class. We analyzed data from the VSI-J, Anxiety Sensitivity Index (ASI), Hospital Anxiety and Depression scale (HAD), and Irritable Bowel Syndrome Severity Index (IBS-SI).
The internal consistency, stability, and factor structure of the VSI-J and its associations with anxiety, depression and severity measures were investigated. ResultsThe factor structure of the VSI-J is unidimensional and similar to that of the original VSI (Cronbach’s alpha = 0.93).
Construct validity was demonstrated by significant correlations with ASI (r = 0.43, p
Conclusion:
These findings suggest that the VSI-J is a reliable and valid measure of visceral sensitivity.
