Exploring the impact of user interface on sustaining usage of citation database -- a study of ABI/INFORM Complete and Science Direct OnSite(SDOS)

[[abstract]]本研究應用結構方程式模型（Structural Equation Modeling，SEM）探討資料庫檢索介面呈現，對影響系統持續使用各因素間的關係。所探討因素包括電腦自我效能、個人特徵、網站回應時間、檢索介面語言、與可用性等。因此以「科技接受模型」探討線上資料庫查詢系統之檢索介面可用性，與個人特徵（學校、性別、經驗）、檢索介面語言、電腦自我效能與網站回應時間的相關程度。研究結果發現：個人特徵（學校、經驗）對於電腦自我效能與認知上易用性之間具有調節效用；個人特徵（性別）對於電腦自我效能與認知上易用性之間並不具有調節效用；不同程度之電腦自我效能對於認知上易用性與檢索系統之可用性具有顯著差異；網站回應時間不同對認知上易用性不具有顯著差異；檢索介面語言不同對於檢索系統可用性亦不具有顯著差異；認知上易用性不同對於認知上有用性及檢索系統介面之可用性具有顯著差異；但認知上有用性不同對於檢索系統介面之可用性具有顯著差異。[[abstract]]This study adopts TAM to explore the related factors that affect the use of interface on sustaining usage of citation database. The study depends on literature analysis and uses the questionnaire to collect data. The collected data is processed and analyzed. Statistical methods adopted in this study are descriptive statistics and structural equation modeling. The results are as follow. I Personnal Characteristic – experience and school significantly affect the perceived ease of use and Computer Self-Efficacy. II Personnal Characteristic – sex does not affect the perceived ease of use and Computer Self-Efficacy. III Computer Self-Efficacy significantly affects the perceived ease of use and interface usability. IV Responsing time does not affect the perceived ease of use. V Language of interface does not affect the use of interface usability. VI The perceived ease of use significantly affects on the perceived usefulness and interface usability. VII The perceived usefulness does not affect the interface usability
