探討鄉村中高齡慢性病患者資訊科技化健康識能與科技接受度之相關性研究

為了解決SN570 Mobile01的問題，作者鄒季蓉 這樣論述：

背景：人口快速老化，慢性疾病與身體功能障礙的盛行率急遽上升，就醫及長照需求負擔繼而增加。延緩失能策略多元興起，疾病自我管理為健康促進重要之一環，隨著醫療科技技術與數位周邊的興盛推進，健康資訊科技化運用亦迅速蓬勃發展。然而，年長者及特定族群之資訊科技化健康識能與科技接受度，是發展健康照護數位系統時需考慮的。目的：本研究旨在探討鄉村中高齡慢性病患資訊科技化健康識能及科技接受度之相關性。研究方法：為橫斷式研究設計之描述性相關性研究，採立意取樣進行收案，對象為雲嘉地區45歲以上中高齡者，經醫師診斷為慢性疾病至某區域教學醫院門診就診者。採結構式訪談問卷進行資料蒐集，包含（1）人口學特性結構問卷；（2）

資訊科技健康照護系統接受度問卷；（3）中文版資訊科技化健康識能量表，來探討中高齡慢性病患資訊科技化健康識能與科技接受度（知覺有用性、知覺易用性、使用意圖）的相關因素分析。經研究倫理委員會審核通過後開始收案，收案時間為民國110年3月至6月。資料分析採描述性統計，與變異數分析、皮爾森積差相關與多元迴歸分析進行推論性統計。結果：有效收案樣本數為120人。資料分析發現相較於全國人口，收案的偏鄉長者的教育程度較低；45%未使用資訊科技健康照護系統；資訊科技化健康識能為中低程度，而科技接受度以「知覺有用性」構面得分最高，「知覺易用性」最低。鄉村地區中高齡慢性病患「性別」、「主要照顧者」、「教育程度」、「

生活費」、「視力狀況」、「擁有智慧型產品數」、「智慧型產品連網方式」及「年齡」等變項，分別與資訊科技化健康識能、和科技接受度具顯著相關（p
