本研究旨在探討親子溝通、同儕互動與大學生性行為之關係。研究對象立意取樣方式，選取臺北市公立大學二所、私立大學四所，包括九個科系及四個年級為施測對象，共計411位，其中男生95位、女生316位。研究工具包括以下四個部份:「個人背景資料調查表」、「親子溝通量表」、「同儕互動量表」「性行為量表」，施測所得之資料採SPSS for Windows統計套裝軟體，以次數分配、平均數、t考驗、卡方考驗、單因子變異數分析、薛費事後比較、皮爾森積差相關及多元逐步回歸等統計方式進行資料分析。研究所得之結果如下:1.大學生與父母親之「親子溝通」狀況，傾向於「中立」狀況。2.在「同儕互動」狀況上，大學生與同儕間之互動，傾向於互動佳的狀況。3.在性行為方面，大學生之性行為有逐年增加的趨勢。此外，有性行為經驗者約佔受試者的四分之一，其中男生有性行為經驗的比率大於女生，且幾乎皆曾採取避孕措施。4.大學生之性行為不會因為親子溝通狀況的不同而有所影響。5.大學生之性行為不會因為同儕互動狀況的不同而有所影響。6.大學生之性行為會因「性別」的不同而有差異在在，其中，男生之性行為較女生為開放，且兩者間有顯著差異存在。7.大學生之性行為，會因「年級」不同而有差異存在，其中以大四最為開放，其次依序是大三、大一、大二。根據上述研究之結果，建議正值男女交往時期的大學生，應加強建立正確的交友態度，尊重異性與自己，學校與家庭均應正視性教育的重要，配合子女成長階段給予適當的性教育，並強化親子的溝通，以雙向的「開放式溝通」取代單向的「問題式溝通」，以期使大學生有更負責的性行為。
