Abstract

Objectives: This study is aimed at assessing the reliability of a standard instrument of diagnosis and assessment for Spleen Qi deficiency pattern questionnaire (SQDQ) and examining the validity of the SQDQ by comparing the pattern identification scores of different groups. Methods: We conducted a survey of 72 participants (60 patients with chronic dyspepsia and 12 healthy subjects) using self-reported questionnaire. Participants were given written consent and this study was performed under the permission of institutional review board of Kyung-Hee university Korean medicine hospital. Results: The reliability and the validity of the questionnaire were inspected. Internal consistency of the SQDQ was excellent. Construct validity analyzed by exploratory factor analysis produced 4 factors, which were selected from eigenvalues that are greater than 1.0. The factor 1, 2, 3 and 4 showed ‘fatigue’, ‘meal’, ‘diagnosis’ and ‘figure’ respectively. For most of SQDQs’ items, there were significant differences observed between the Spleen Qi and the non-Spleen Qi groups. However, the ‘emaciation’, ‘tongue diagnosis’ and ‘pulse diagnosis’ showed no significant differences. Conclusions: The SQDQ restructured in this study may provide a fundamental questionnaire and a further study is required for a more advanced, standardized and statistically proven questionnaire.
