跨媒介新聞消費行為越來越普遍，但我們仍不知閱聽眾願意從多個媒介消費新聞的原因。因此，本研究根據跨媒介新聞消費的特殊性修正資訊來源擴大理論，以發展出跨媒介新聞資訊處理模型，並根據此模型找出上述問題的答案。實驗結果顯示高新聞資訊效用感知是跨媒介新聞消費的主要原因，而該變項依序是受到新聞可信度、新聞相關性與新聞新奇性三者的影響。此發現不但補足先前論點的不足，也顯示跨媒介新聞資訊處理歷程有其特殊性。

Although increasingly more people read news from multiple media outlets, little is known on why they are willing to focus on and are motivated to process the news in a subsequent medium. This study investigated the reasons behind this progressive phenomenon. Considering the uniqueness of cross-media news consumption, this study developed a cross-media news information processing model, which was revised according to source magnification theory. This study employed a 2 (high and low news independence) x 2 (high and low news relevance) x 2 (high and low news credibility) factorial design. The results showed that perceived news information utility was the key reason. News credibility, news relevance, and news novelty were the three antecedents that affected the level of perceived information utility. These findings not only complement previous assertions made by other scholars, but also demonstrate the uniqueness of cross-media news information processing.
