目的：本研究調查衛教介入對門診手術患者術前情境焦慮的影響，同時也試圖確定影響其術前情境焦慮的因素。

方法：研究對象包括接受局部麻醉進行門診手術的患者。總計收案人數193人，實驗組110人、對照組83人。對照組使用醫院常規衛教指導，實驗組觀看「手術全期衛教影片」。

結果：在觀看手術全期衛教影片介入後，實驗組的平均焦慮分數從40.3±8.8下降到38.2±9.1。同時，女性、疼痛耐受性、特質焦慮、手術經驗以及親友陪伴為術前焦慮的主要預測因子。

結論：「手術全期衛教影片」提供手術相關訊息，有效降低術前情境焦慮；同時了解術前情境焦慮之預測因子，可提供臨床護理人員辨識病人特性及如何解決患者的焦慮。

Purpose: This study investigated the influence of a health education intervention on the preoperative state anxiety of outpatient surgery patients, while also seeking to confirm the factors influencing their preoperative state anxiety.

Methods: The subjects consisted of patients who received local anesthesia for outpatient surgery. There were total 193 patients participated, including 110 in the experimental group and 83 in the control group. The patients in the control group received the regular health education guidance provided by the hospital, while the patients in the experimental group watched a "surgery- period health education film". Results: After the intervention consisting of watching the surgery- period health education film, the mean anxiety score of the experimental group dropped from 40.3 ± 8.8 to 38.2 ±9.1. Meanwhile, female gender, pain tolerance, trait anxiety, surgical experience, and the company of friends and family were found to be the main predictors of preoperative anxiety.

Conclusions: The surgery-period health education film provides surgery-related information that effectively reduces patients’ preoperative state anxiety, while knowing the predictors of preoperative state anxiety could assist clinical nursing staff in identifying how patients’ anxiety can be addressed.
