BACKGROUND/OBJECTIVE: The diagnosis and treatment of functional dyspepsia (FD) require a systematic and tailored approach. In traditional Korean medicine (TKM), pattern-identification tools help analyze clinical information and guide treatment. This study aimed to develop a Korean version of the standard tool of pattern identification for functional dyspepsia (STPI-FD) and subsequently assess its reliability and validity.
Common patterns and symptoms were identified through a systematic review of the clinical studies conducted in Korea and China. An importance survey for each pattern and symptom was conducted using the Delphi method and refined through expert consensus. A draft STPI-FD comprising six patterns and 38 items was developed. Ninety-five patients with FD completed the STPI-FD along with the Visual Analog Scale, Total Dyspepsia Symptom scale, Single Dyspepsia Symptom scale, and Functional Dyspepsia-related Quality of Life questionnaire.
Two items were excluded from the STPI-FD due to their negative impact on reliability, resulting in a 36-item tool. The revised STPI-FD demonstrated high internal consistency, with an overall Cronbach's alpha of 0.942. In contrast, the Cronbach's alpha values for each pattern ranged from 0.7 to 0.9. To assess its validity, significant differences in the pattern characteristics and associated symptoms were confirmed, indicating its clinical relevance. Statistically significant positive correlations between the revised STPI-FD and other dyspepsia-related scales underscore the differentiation between patterns.
The final STPI-FD is a moderately reliable and valid tool for diagnosing specific patterns in FD, supporting the selection of interventions and the evaluation of symptom improvement in patients treated with TKM.
背景/目的：功能性消化不良（FD）的诊断和治疗需要系统且个性化的方法。在传统韩医学（TKM）中，辨证工具有助于分析临床信息并指导治疗。本研究旨在开发功能性消化不良辨证标准工具（STPI-FD）的韩文版，并随后评估其信度和效度。
通过对韩国和中国开展的临床研究进行系统评价，确定常见证型和症状。采用德尔菲法对每个证型和症状进行重要性调查，并通过专家共识进行完善。制定了一个包含六种证型和38个条目的STPI-FD草案。95例FD患者完成了STPI-FD，同时完成了视觉模拟量表、消化不良总症状量表、单一消化不良症状量表和功能性消化不良相关生活质量问卷。
由于对信度有负面影响，STPI-FD中排除了两个条目，最终形成了一个36个条目的工具。修订后的STPI-FD显示出高内部一致性，总体Cronbach's α系数为0.942。相比之下，每个证型的Cronbach's α系数范围为0.7至0.9。为评估其效度，证实了证型特征和相关症状存在显著差异，表明其具有临床相关性。修订后的STPI-FD与其他消化不良相关量表之间存在统计学显著正相关，突出了证型之间的差异。
最终的STPI-FD是一种用于诊断FD特定证型的中度可靠且有效的工具，有助于支持传统韩医学治疗中干预措施的选择和症状改善的评估。
