Examining the use intention of mobile health applications among the public based on the technology acceptance model

背景：全球網路資訊的蓬勃發展，各式各樣的行動健康應用程式雨後春筍般出現，民眾可透過智慧型手機或平板電腦裝置mHealth apps，使用者有多元選擇及創造附加價值服務。 目的：應用科技接受模式探討行動健康應用程式使用意願，並比較有無曾經使用者之差異。 方法：本研究採橫斷式研究設計，採用問卷調查法來進行研究資料的蒐集，自2021年2月至4月於台灣南部某區域醫院之門診民眾進行問卷發放，回收有效問卷1,014份。 結果：曾經使用mHealth App經驗417人(41.12%)、未曾使用mHealth App經驗597人(58.88%)。兩者在認知易用性、認知有用性及態度，達顯著水準(p＜0.001)，使用行為意圖兩者之平均值都為3.98分，未達顯著差異(p =0.921)。影響使用行為意圖的因素，曾經使用過mHealth App經驗，為態度達統計顯著水準( p＜0.001)；未曾經使用過mHealth App經驗，則有認知易用性、認知有用性及態度達統計顯著水準(p＜0.05)。 結論：提高使用者態度，有助於民眾對mHealth apps之使用及正向支持，亦能進行健康管理及快速了解及使用醫院所提供醫療資訊。

Background: With the rapid development of global Internet resources, various mobile health applications (mHealth apps) have been introduced. mHealth appscan be installed on smartphones and tablets, providing users with multiple options and value-added services. Aim: Apply technology acceptance model to explore the willingness to use mobile health applications, and compare whether there are any differences between previous users. Methods:A cross-sectional study design was adopted, and questionnaires were used to collect research data from outpatients in a regional hospital in southern Taiwan from February to April 2021. In total, 1014 valid questionnaires were collected. Results: There were 417 (41.12%) and 597 (58.88%)respondents who had and had not previously used mHealth apps, respectively. There were significant differences in the perceived ease of use, perceived usefulness, and attitudes between the two groups (p＜0.001).The mean values of usage behavior intentions of the two groups were3.98 points, with no significant differences (p=0.921).Factors affecting behavioral intention, including the attitude of respondents who were experienced in using mHealth apps, showed significantfindings (p＜0.001). Moreover, perceived ease of use, perceived usefulness, and attitudes in subjects who had not used mHealth apps showed significantfindings(p＜0.05). Conclusion: Improving user attitudes will help people to use and positively support mHealth apps, and they can also perform health management and quickly understand and use the medical information provided by the hospital.
