本研究採用橫斷法，以叢集取樣抽取台灣地區14所高中職校，共3470名有效樣本。研究發現：1.高中職生的情緒智慧呈現中等以上程度，不同性別、公私立、高中職、憂鬱傾向變項有顯著差異，年級則無；2.整體高中職生的憂鬱傾向雖未達明顯憂鬱程度，但不低，高達33.2%學生明顯憂鬱，不同性別、情緒智慧類別變項有顯著差異，公私立、高中職、年級則無；3.情緒智慧(整體、自我、人際)與憂鬱傾向之間呈現顯著負相關，特別是自我情緒智慧的預測力較明顯；4.不同性別高中職生的情緒調整狀況各方面存在明顯差異，並發現：心情好的最主要原因為人際關係，心情好時通常自己開心並與別人分享，心情不好的主要原因為學業與人際關係，心情不好時通常傾向轉變自己的想法和心情，想要讓自己心情變好時主要選擇放鬆分心與尋求支持，心情不好時通常選擇獨自處理，想要找人讓心情變好時主要選擇朋友，想要讓別人心情變好時主要選擇給予支持與放鬆分心，認為要讓心情變好的最佳處理方式為放鬆分心與問題解決，多數高中職生對於自己平常情緒反應的評價為尚稱不錯。本研究也提出六點建議提供實務服務與後續研究之參考。 The study measured 3470 valid students of 14 senior and vocational high schools in Taiwan with cross-sectional method and cluster sampling.
