本研究旨在針對一名極重度多障孩童，設計一套適宜的如廁訓練方案，同時採用研究者自行研發的無線傳輸排泄警示器，解決其無法自行至廁所如廁的問題。本研究係採單一受詴研究法之逐變標準設計，分為基線期、處理期、撤除期及追蹤期等四個階段。結果顯示：(一) 本訓練方案能建立個案主動至廁所使用馬桶如廁的技能，而且在方案撤除後能繼續保持；(二) 無線傳輸排泄警示器不僅訊號傳輸準確度高 (96.52%)，且訓練者使用後甚為滿意。由此可知，本研究所設計的如廁訓練方案及無線傳輸排泄警示器，不僅對個案的如廁行為具有良好的訓練成效，更可供國內教育人員、醫療人員、養護人員、身障孩童家長、相關專業人員、產品開發人員之參考。

The present study adopted changing-criterion design of single subject study to assess the effectiveness of toilet training program and the wireless urine-alarm (WUA) applied for a 10 year-old boy with profoundly multiple disabilities. The results appeared that (1) the subject formed the habit of initiative urinating in the stool in the restroom and remained urinating initiatively after training, and (2) the accuracy of signal transmitted from the WUA was up to 96.52% and the trainers were very satisfied with this new apparatus. Implications of this study were also discussed.
