The Short-Form Leeds Dyspepsia Questionnaire is a reliable, valid, and responsive tool for measuring dyspepsia symptoms. This shorter version is more convenient for self-completion in clinical trials.

Area of Science:

  • Gastroenterology
  • Clinical Trials Methodology

Background:

  • Dyspepsia symptom assessment is crucial for clinical trials.
  • The original Leeds Dyspepsia Questionnaire is effective but lengthy and not self-completed.
  • A shorter, self-completed version, the Short-Form Leeds Dyspepsia Questionnaire, was developed.

Purpose of the Study:

  • To evaluate the Short-Form Leeds Dyspepsia Questionnaire's acceptability, interpretability, internal consistency, reliability, validity, and responsiveness.
  • Assessment was conducted in both primary and secondary care settings.

Main Methods:

  • The Short-Form Leeds Dyspepsia Questionnaire was administered to 388 primary care and 204 secondary care patients.
  • Test-retest reliability was assessed over 2 days.
  • Validity was determined by comparing with general practitioner diagnoses, and responsiveness was measured before and after treatment for endoscopically confirmed disease.

Main Results:

  • The questionnaire demonstrated high test-retest reliability (Pearson coefficient = 0.93).
  • It achieved a sensitivity of 77% and specificity of 75%.
  • A statistically significant response to change was observed (P < 0.005).

Conclusions:

  • The Short-Form Leeds Dyspepsia Questionnaire is a reliable, valid, and responsive measure for dyspepsia symptom frequency and severity.
  • It offers a more convenient and shorter alternative to the original Leeds Dyspepsia Questionnaire for self-administration.
  • This tool enhances outcome measurement in dyspepsia research and clinical practice.
