高齡者常因不熟悉智慧型手機使用方式，造成操作失誤或資料刪除等問題。除了使用行為的的困境之外，高齡者也要面對大量網路訊息。資訊內容是否影響高齡者行為，他們的角色是參與討論還是轉換成傳播者，這些都是是值得探討的問題。本研究透過內容分析法，由高齡者Line群組各式訊息中過濾出謠言，進行內容編碼與找出訊息頻率與群組內成員互動情形。經過分析，高齡者對於政治議題，健康問題和勵志故事的比例最高，很容易被轉傳和引起關注。大量傳遞特定訊息的行為也造成了群組織內的爭端，群組成員甚至會選擇退出群組表示抗議，少數的成員會直接的反駁與爭執，呈現個人不同的喜好差異與反應行為。多數高齡者以直覺或感覺的方式看待謠言，並不會進行內容的檢驗，也不太在乎訊息的真偽。證明高齡者行容易被操縱，謠言經過變形，利用高齡者所關心的議題，透過人為改寫增加可信度，達到傳播謠言的目的。
