前言：疼痛評估視病人自評疼痛程度為「黃金標準」（gold standard）。台灣疼痛醫學會發展Pain Face Scale，並授權台中榮民總醫院使用。臉譜設計包含六種疼痛表情及顏色變化，本研究目的為驗證Taichung Veterans Pain Face Scale（TVPFS）之信效度。

材料與方法：採立意取樣，於中部某醫學中心病房收案，共有70名受試者。研究採前、後測設計，先請受試者依不痛至最痛依序排列六張TVPFS臉譜，之後請受試者接受（1）靜脈注射，及（2）傷口換藥前、中、後時以TVPFS及NRS自評疼痛強度。結果：70位所有受試者依據共排列140次，正確排列者佔93.6%。

區辨效度方面，請受試者以TVPFS自評疼痛，受試者在靜脈注射及傷口換藥前、中、後三次測量皆呈現顯著差異（X^2=106.29, p＜.001；X^2=104.89,p＜.001）。

換藥中的TVPFS顯著高於靜脈注射中（p＜.001）。效標關聯效度方面，病人接受靜脈注射及換藥時的TVPFS，與其NRS自評疼痛分數呈正相關（p＜.01）。

討論：TVPFS在疼痛評估上，是一個有效的工具，但有一臉譜需要再修改。

建議修改TVPFS後進一步研究，以確定TVPFS在病人疼痛評估上之效益。

摘要 Summary

Foreword: Pain assessment regards the patient's self-assessment of pain as the ＂gold standard＂. Taiwan Pain Society developed the Pain Face Scale and authorized it to be used by Taichung Veterans General Hospital. The facial makeup design includes six pain expressions and color changes. The purpose of this study is to verify the reliability and validity of the Taichung Veterans Pain Face Scale (TVPFS). Materials and methods: A sample was taken intentionally, and the case was collected in a ward of a medical center in the central part. There were 70 subjects in total. Study the pre- and post-test design. First, the subjects were asked to arrange six TVPFS facial masks in order from no pain to the most pain, and then the subjects were asked to receive (1) intravenous injection, and (2) before, during, and after the wound dressing change. Later, the pain intensity was evaluated by TVPFS and NRS. Results: All 70 subjects were ranked 140 times according to the total, and 93.6% were correctly ranked. In terms of discriminative validity, the subjects were asked to self-assess pain with TVPFS. The subjects showed significant differences in the three measurements before, during and after intravenous injection and wound dressing (X^2=106.29, p＜. 001; X^2=104.89), p＜.001). The TVPFS in dressing change was significantly higher than that in intravenous injection (p＜.001). In terms of the validity of the standard correlation, the TVPFS of patients receiving intravenous injection and dressing changes was positively correlated with their NRS self-rated pain score (p ＜.01). Discussion: TVPFS is an effective tool for pain assessment, but there is a Facebook that needs to be revised. It is recommended to modify TVPFS and further research to determine the effectiveness of TVPFS in patient pain assessment.
