The aim of this study was to examine the convenience of the quality of life and utility evaluation survey technology (QUEST) questionnaire and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire as self-assessment diagnostic instrument.
This was a two-way crossover study conducted over 6 weeks from September 2010 to November 2010. The subjects were 60 consecutive patients admitted to the Hiratsuka city hospital with a gastrointestinal condition, regardless of the coexistence of heartburn. They were assigned to fill in both the QUEST and FSSG questionnaires in random order. We analyzed the time taken to complete the questionnaires, whether subjects asked any questions as they filled in the questionnaire, and the questionnaire scores.
Comparison of the QUEST and the FSSG revealed significant differences in the completion time (196.5 vs. 97.5 seconds, respectively; P < 0.0001) and in whether subjects asked any questions (37 vs. 15 subjects, respectively; P < 0.0001). Completion time in QUEST scores of ≥ 4 was lower than < 4 (170.5 vs. 214.0 seconds, respectively; P = 0.022), and the QUEST score was significantly higher without questions than with question (3 vs. 1 points, respectively; P = 0.025).
This study revealed that the FSSG questionnaire may be easier for Japanese subjects to complete than the QUEST questionnaire.
