本研究旨在瞭解超過適婚年齡，且從未結婚單身者，並依據Stein之分類架構， 將單身者區分為矛盾型、決心型、希望型與悔恨型；另將目前擁有親密伴侶的單身者區分為 伴侶型。藉此探討不同背景變項、不同單身類型，其社會支持知覺與其心理健康之關係。以 方便取樣抽樣247位有效樣本作為研究對象。研究者根據受訪本在「單身取向問卷」、「社會 支持問卷」、「心理幸福滿足感量表」的填答內容，進行統計分析。 　　在單身類型的分佈上，以希望型與伴侶型最多，隨年齡增加，各類型的分佈較分均。單 身者的社會支持知覺，會因教育程度不同而有差異；而且家人此一支持網絡的重要性甚於朋 友支持網絡。而單身者的心理健康情形，會因性別、年齡不同而有所差異。 　　另外，本研究亦初步驗証，單身者因為持單身的動機與態度不同確能影響其心理健康與 生活適應，在各類型中，悔恨型單身者是適應較差的族群，研究者依據研究結果加以討論， 並提供若干建議，作為參考依據。
