整合自我效能、信任、組織支持與動機因素探索醫療知識庫系統之使用意圖－－以台灣某教學醫院為例

The Integration of Self-Efficacy, Trust, Organizational Support, and Personal Motivation to Explore Behavioral Intention of Health Knowledge Repository Systems-an Empirical Study of Teaching Hospital in Taiwan

本研究以技術接受模式為基礎，整合自我效能、信任、組織支持與動機因素，以解釋台灣某教學醫院員工對知識庫系統之使用意圖。經過相關分析、迴歸分析與變異數分析之驗證。研究結果發現：（1）易用性認知、制度信任、人際信任、組織支持分別對有用性認知、主觀規範、愉悅性認知均有正向顯著性的影響。（2）有用性認知、主觀規範與愉悅性認知對醫療知識庫系統的使用意圖也均有正向顯著性的影響。（3）值得注意的是：輸出品質對有用性認知與愉悅性認知的影響均不顯著，而人際信任與制度信任對兩者的影響卻都顯著，顯示信任因素的重要性比輸出品質來的重要。（4）在差異性分析方面，性別、主管與非主管、職務類別對某些研究變項有顯著差異，而年齡、學歷、年資等變項對所有研究變項則無顯著差異。本研究可以作為未來研究之基礎，且當知識庫系統最初引進於醫院時，也可以提供給組織管理者一些實務的洞視與方案。

Based on TAM (Technology Acceptance Model), the purpose of the present study is to integrate self-efficacy, trust, organizational support, and personal motivation into TAM to explain the behavioral intention of health knowledge repository systems of one teaching hospital’s employees in Taiwan. The findings show: (1) perceived ease of use, institutional trust, interpersonal trust, and organizational support all have significantly influence on perceived useful, subjective norm, and perceived enjoyment. (2) Our findings also suggest perceived useful, subjective norm, and perceived enjoyment as three important antecedents directly influence users’ intention to use system. (3) In addition, among the antecedents, output quality hasn’t significant influence on perceived useful and perceived enjoyment. Furthermore, interpersonal trust and institutional trust are two significant determinants of perceived useful and perceived enjoyment. That is, interpersonal trust and institutional trust are more important than output quality to predict perceived useful and perceived enjoyment. (4) Gender, supervisor or not, and the kinds of professionals have significant difference on certain constructs, whereas age, educational level, and work experience have not significant difference on all constructs The findings may be used as theoretical base for future research and can also offer empirical foresight and practical solutions to managers of organizations when the knowledge repository systems are being introduced initially into the hospitals.
