本研究旨在探究護理科學生於愛情心理學課程中，對於性知識、性態度和性行為的影響。本研究採用「準實驗不等組前測－後測設計」，以北區某護理專科學校之護理科5年級學生12個班級進行研究。針對12個班級分為三組：一共18週的課程，共36小時，實驗組A學生共5班，接受愛情心理學，含6週性學課程；實驗組B學生共4班，接受愛情心理學，含1週性學課程；對照組C學生共3班，未接受任何愛情相關課程。研究對象皆在課程前，與課程後接受「性知識、性態度、性行為量表」問卷，以單因子共變數分析等統計方式進行分析，試圖了解研究愛情心理學課程對性知識、性態度與性行為之效果與差異。本研究結果發現：（1）不同愛情心理學課程設計與教學，對於護理科學生「性知識」並無影響；（2）不同愛情心理學課程設計與教學，對於護理科學生「性態度」與「性行為」有影響，兩者得分後測分數顯著提升；（3）不同愛情心理學課程設計與教學，在控制前測分數之下，實驗組A在「性態度」與「性行為」之後測得分顯著高於實驗組B與對照組C。最後，本研究將依據研究結果進行討論與建議。
