本研究將探討在現代資訊多元化的消費環境中，女性消費者對於購買保養品前，各種相關資訊來源的信任程度，並深入瞭解其是否會影響女性消費者的購買意願，同時試圖研究涉入程度是否會對資訊來源信任與購買意圖之間，產生干擾作用。 本研究以問卷方式進行量化研究分析，採用網路問卷與紙本問卷方式發放，回收樣本共178份，有效樣本共計171份，有效回收率為96.07％。 本研究採用路徑分析進行驗證變數間的因果關係。實證結果顯示，女性消費者對於「親友建議的信任」、「廣告代言人的信任」、「產品製造技術的信任」、「傳統大眾傳媒的信任」以及「產品品牌的信任」，會正向影響其對於保養品的購買意願。此外，涉入程度不同，確實會對資訊來源信任與購買意願間造成干擾。 This research is focsing on how the female consumers will trust the information from various different sources before buying the cosmetic productions in this modern, fast-developed society.
