預防醫療尖銳物品扎傷錄影帶製作及其教學成效之探討

The Study of Video Tape Production and Its Instruction Effectiveness for the Prevention of Sharp Inhury in Medical Treatment

本研究目的在運用數位科技製作「預防針扎錄影帶」，並以實驗法驗證媒體教學成效，以調查法驗證收視成效。錄影帶腳本係採專家效度，經12次修改後完成腳本製作，錄影帶初版製作完成後，採護理專家滿意度評審，經專家建議修改兩次後，完成錄影帶製作。媒體教學成效是以知識問卷表為測驗工具，收視成效是以收視滿意度調查表為工具，將91年I月1日至91年II月30日進入本院之新進人員32名為研究對象，依來院先後次序間隔分入實驗組及對照組。對照組與實驗組基本屬性經焰驗證無顯著差異，兩組知識問卷表前測亦蕪顯著差異;但實驗組之知識問卷表前後測經pairttest驗證後則有顯著差異，由平均數可知實驗組後測平均得分大於前測;實驗組與對照組後測比較，亦有顯著差異，且由平均數可知實驗組後測平均得分大於對照組後測。由收視滿意度調查可知，32位收視者都覺得「預防針扎錄影帶」對其有幫助，幫助程度得分在4．72-4.78介於非常有幫助及有幫助之間;對影片影質清晰度、錄影帶內容、整體滿意度得分在4．34-4.47介於滿意與非常滿意之間，影片放映時間得分為3．75，介於尚可/適中與滿意之間。曲於收視者未對錄影帶有任何修改建議，所以錄影帶製作正式完成。

The objective of this study is to use digital technology to produce videotape that prevents injuries caused by sharp medical supplies. This study used experimental methods and questionnaires to assess the effectiveness of this teaching media. The contents of this video had been amended twelve times and the production process was highly professional. The specialists?satisfaction level on the first version of the video was assessed. Under the specialists?recommendations, the video had been amended twice before the final production. The effectiveness of this teaching media was assessed by the knowledge questionnaires, and the visual effectiveness was assessed by satisfaction level questionnaires. The experiment subjects were 32 new personnel recruited to our hospital between January 1st, 2002 and November 30th, 2002. The experimental subjects were assigned alternatively to experimental group and control group based on the order of recruitment dates. The attributes of the subjects in both the experimental and control group had no significant differences, as shown in the χ2 test. The results of the pre-test knowledge questionnaires for both groups also showed no significant differences. The data of the knowledge questionnaires of the experimental group were analyzed by pair t test. The pre-test and post-test results showed significant differences . The average score of the post-test of the experimental group was higher than that of the pre-test. There were also significant differences between the scores of the post-tests of the experimental and control groups .The average score of the post-test of the experimental group was higher than that of the control group. The data from the satisfaction level questionnaires showed that experimental subjects found the video helpful for them. The level of helpfulness scored 4.72-4.78, which was between the helpful and very helpful levels. The visual clarity, video contents, and the overall satisfaction scored 4.37-4.47, which was between satisfied and very satisfied levels. The length of the video scored 3.75, which was between acceptable/moderate and satisfied levels. Since the experimental subjects did not provide any suggestions for improvement, the video production is now officially finished.
