摘要

Purpose

This study aimed to translate and validate the Danish version of the DV-QOL questionnaire, originally developed in 2015, to assess the impact of diverticular disease on quality of life (QOL) in Danish-speaking patients with diverticulosis.

Methods

Following international standards, the DV-QOL was translated. A cross-sectional survey was conducted in 2023 with Danish-speaking subjects. The survey included the Danish DV-QOL, an anchor QOL question, and the EuroQol visual analogue scale. Psychometric properties were evaluated for validity, internal consistency, and the ability to identify significant impacts on QOL.

Results

The validation cohort included 16,766 subjects. The DV-QOL score showed a strong correlation with overall QOL (p < 0.001) and high discriminative validity (p < 0.001). Reliability was confirmed with an inter-item correlation of 0.41 and a Cronbach’s α of 0.92. The score accurately identified patients with a significant impact of bowel function on QOL, achieving 82% sensitivity and 79% specificity.

Conclusion

The Danish DV-QOL is a valid and reliable tool for measuring diverticular disease-specific QOL, beneficial for both clinical and research applications in understanding the impact of the disease and patient outcomes.
