本研究旨在探討老人人口特質、社會支持是否會對老人生活滿意度產生影響，並檢驗工具性、情緒性與訊息性社會支持與生活滿意度的相關性以及三者的影響關係。研究資料為對南投縣65 歲以上老人進行實證調查研究，並採叢集抽樣法，抽取700 位老人進行問卷調查，計回收有效問卷454 份，並使用描述性統計、獨立樣本t 檢定、單因子變異數分析、皮爾森積差相關與迴歸分析等研究方法，進行相關統計檢定。本研究結果發現，社會支持與老人生活滿意度有正相關，社會支持愈多者，生活滿意度愈高，社會支持的主要來源為非正式支持體系之家庭成員及鄰居朋友，社會支持對老人生活滿意度最具影響力。針對此研究結果顯示，建議日後推動老人福利相關政策或措施時，應重視老人家屬參與以及社區支持體系的建構，以確保未來老人生活品質。
