| 摘要: | 人格特質會影響一個人的思考、行動甚至喜好，大五人格廣泛應用於飲食行為分析的研究。台灣由於咖啡館林立造就了眾多的咖啡飲用人口，消費者也各自有其偏愛的咖啡種類。因此本研究試圖從受測者的大五人格特質探討對於咖啡飲用習慣上的影響。
飲用頻率上，黑咖啡飲用天數正相關謹慎負責性，並具有3%解釋力；無糖拿鐵飲用天數負相關親和性，並具有6.5%解釋力；有糖拿鐵飲用天數負相關外向性、謹慎負責性、開放性，並分別具有5.7、2.3、3.1%解釋力，同時以此三種人格進行多元回歸的解釋力達7.2%；日常有咖啡飲用習慣者，人格特質影響的顯著性會更加明顯。飲用偏好上，以大五人格分數應用支持向量機進行咖啡種類的喜好預測，準確率達74.1%。總體可發現咖啡飲用習慣的確與受測者的人格特質具有關聯性。
