背景
大腸鏡是最佳的腸道疾病篩檢工具，但是，此項檢查常令病人感覺疼痛與不舒服，因而降低病人接受檢查的意願。

目的
探討大腸鏡檢查前提供病人相關檢查訊息對降低檢查焦慮與疼痛的影響，以及確認執行大腸鏡檢查病人對疼痛與焦慮的影響因子。

方法
採類實驗性研究（Quasi- experimental design），以接受非無痛麻醉之大腸鏡檢查之門診 病人為研究對象。研究期間為2011 年1–4月，實際收案人數為213人，其中實驗組103 人、控制組110人。所有研究對象皆接受醫院常規照護，但實驗組則需觀看「檢查過程 指引」多媒體衛教光碟。

結果
實驗組經由衛教介入後，情境焦慮分數由48.7 分（± 11.6），降為39.2 分（± 8.7）。實驗 組的檢查疼痛分數顯著低於控制組（3.8 ± 2.5 vs. 5.0 ± 2.7）。特質焦慮、性別與教育程 度是情境焦慮的主要預測因子；而情境焦慮是大腸鏡檢查疼痛的重要預測因子。

結論／實務應用
經由多媒體衛教光碟提供大腸鏡檢查過程相關訊息，可有效降低病人的焦慮與疼痛。

Background: Colonoscopy is currently considered the best screening tool in the diagnosis of colon diseases. However, this procedure often causes pain and discomfort in patients, thus reducing patient willingness to undergo and comply with this procedure. Purpose: This study explores the effects of providing procedurerelated information to patients receiving colonoscopy in terms of anxiety and pain reduction and identifies factors that influence the pain and anxiety experienced by patients during this procedure. Methods: This study adopted a quasi-experimental design that targeted colonoscopy patients in outpatient clinics. Two hundred thirteen patients were recruited, with 103 patients in the experimental group and 110 in the control group. Participants were recruited between January and April 2011. All of the participants received standard care, and only those participants who were assigned to the experimental group were asked to watch ‘‘A Guide to the Colonoscopy Procedure,’’ a multimedia health informatics CD-ROM. Results: Anxiety scores of the experimental group dropped from 48.7 T 11.6 to 39.2 T 8.7 after the intervention. The average pain score of the experimental group was significantly lower than that of the control group (3.8 T 2.5 vs. 5.0 T 2.7). Furthermore, trait anxiety, gender, and educational level were identified as the main predictors for state anxiety, and state anxiety was identified as an important predictor for pain during the colonoscopy examination. Conclusions/Implications for Practice: This study found that using a multimedia health informatics CD-ROM to provide information on the colonoscopy procedure effectively reduced the examination-related anxiety and pain of patients.
