The impact of dyspepsia on symptom severity and quality of life in adults with headache.

Background: Dyspepsia and headache frequently co-exist, but the clinical implication of this association is uncertain. We planned to examine the prevalence and impact of dyspepsia in adults with headache.

Methods: A cross-sectional study was conducted in a secondary care setting.

Mandarin version of the Leeds Dyspepsia Questionnaire: A valid instrument for assessing symptoms in Asians.

Objective: To develop and validate a Mandarin version of the Leeds Dyspepsia Questionnaire (M-LDQ) in Asian patients with dyspepsia.

Methods: The M-LDQ was developed according to standardized methods. The validity, internal consistency, test-retest reliability and responsiveness of the instrument were evaluated in both primary and secondary care patients.

There is a lack of validated instruments assessing dyspepsia symptoms in the Asian region. We aimed to translate and validate the Leeds Dyspepsia Questionnaire (LDQ) in a multi-ethnic Asian population.
