多重資訊來源對於網站評估的影響

Abstract

本論文旨在全面探討網路讀者與使用者如何理解健康網站的資訊品質、可信度和網站整體評估。實證研究證明，網站的資訊特徵和設計特性對於資訊品質、可信度和網站評估有重要影響。過去文獻也驗證多重來源的資訊驗證相較於單一來源的資訊驗證更具有說服力與可信度。然而，很少有研究著重於整合多個不同的網站來源，並檢驗資訊特徵和網站設計特性，尤其是與健康相關的網站。鑑於許多人不可避免地喜歡在多個網站上尋求與驗證健康資訊，以幫助他們了解自己的健康狀況。為了填補這個研究缺口，本論文探討了多個健康網站來源中的資訊整合，驗證資訊特徵對於感知資訊品質和可信度的影響，以及視覺化的設計特性對於感知網站說服力、用戶行為意圖的影響。因此，本論文中包含的兩個研究都是基於多個健康網站來源整合所進行的實驗設計。

This dissertation aims to comprehensively understand how online readers and users make sense of information quality, credibility, and website overall evaluation of healthcare websites. Empirical studies have confirmed that the information characteristics and design features substantially impact information quality, credibility, and website evaluation. Past literature also proved that information verification from multiple sources is more persuasive and credible than a single source. Nevertheless, few studies have looked at integrating multiple website sources and examined the information characteristics and design features, especially in health-related websites. In view of many people unavoidably prefer to search and verify health information across many website sources to help them understand their health conditions. To fill this research gap, this dissertation explores the integration of healthcare information from multiple website sources. This dissertation examines the impact of information characteristics on perceived information quality and credibility, as well as the effect of the visual design features on perceived website persuasiveness and behavior intentions of users, respectively. Hence, two essays in this dissertation are based on the experimental designs of multiple healthcare website sources.
