背景：大學生值青少年轉成人期過渡階段，亦面臨多變社會，憂鬱情緒是重要健康問題，文獻提到有憂鬱傾向者其情緒辨識表達障礙比率較高，此議題值得重視，研究有助擬定促進大學生心理健康策略參考。目的：探討憂鬱傾向大學生之情緒辨識表達特徵及其障礙風險。方法：橫斷性描述性設計，採分層集束隨機抽樣從南部某大學抽出600位同學，以曾氏自陳憂鬱量表及多倫多述情量表收集資料，回收率76%。經邏輯迴歸調整干擾變項，檢定憂鬱傾向有無，出現情緒辨識表達障礙危險對比值（odds ratio）。結果：有憂鬱傾向占48.8%，有情緒辨識表達障礙占38.3%。出現情緒辨識表達障礙現象，在憂鬱傾向者中有56.5%，而無憂鬱傾向者僅20.9%。經邏輯迴歸調整人口特徵，憂鬱傾向者是無憂鬱傾向者有情緒辨識表達障礙之危險比為4.9倍（p < .001）。結論：大學生有憂鬱傾向者有較高風險出現情緒辨識表達障礙，學校心理衛生專業人員需關注並促進其心理健康及情緒辨識表達能力。

Background: Depression is a significant health problem in undergraduate students, exacerbated by factors that include the transition into adulthood and the changes in social environment. Research has shown depressive tendency and alexithymia as positively correlated. Greater attention to the issue of depression in undergraduate students is needed in order to facilitate appropriate strategies to promote mental health. Objectives: This study was designed to identify the association between depressive tendencies and the identification and expression of emotional obstacles in undergraduate students. Methods: A cross‐sectional and descriptive research design was conducted. A stratified cluster approach randomly selected a total of 600 undergraduate subjects from a university in southern Taiwan. The response rate for the self‐administrated questionnaire was 76%. Measurement tools used included Zung's Self‐Rating Depression Scale and the Toronto Alexithymia Scale‐20. The odds ratio of depressive tendency and the identification and expression of emotional obstacles among undergraduate students was calculated, and then the association between the two variables was examined using logistic regression, with confounding variables taken into account. Results: In total, 48.8% and 38.1% of participants suffered from depressive tendencies and the identification and expression of emotional obstacles, respectively. Findings showed that slightly over half (56.5%) of those with depressive tendencies identified and expressed emotional obstacles. This percentage was only one‐fifth (20.9%) among those without depressive tendencies. The odds ratio for identification and expression of emotional obstacles among those with depressive tendencies was 4.9 times (p < .001) that of their peers without depressive tendency as calculated using logistic regression adjusted for gender, age, and academic department. Conclusions: Undergraduate students with depressive tendencies face a significantly higher risk of identifying and expressing emotional obstacles. School mental‐health professionals may use the results of this study to promote mental health and improve the accurate identification and expression of emotions.
