本研究主要在探討中高齡人口選擇老人福利機構做為養老方式的可能性，並探討影響其進住機構養老的決定因素。研究對象為50 歲以上之人口，研究資料取自2005年老人狀況調查原始資料。研究結果顯示，女性受訪者對於選擇老人福利機構的可性較男性高，教育程度愈高則愈有可能進住老人福利機構，但擁有的子女數愈多則愈不可能進住老人福利機構。在不同世代選擇機構養老的決定因素上，對50 至64 歲的人口而言，是否採取機構養老方式多與傳統觀念有關，例如教育程度或擁有的子女數。但對65 歲以上的人口而言，他們會依據自己目前所處的狀況及擁有的資源多寡來決定養老生活方式，所以其預測的因素大多與其所處的現實環境有密切關係，例如年齡、經濟來源等。研究者據此提出結論和建議。
