本研究旨在考驗所提之因果模式，並從中探討罪惡感與羞愧感在因果模式中之中介角色，以及兩者與憂鬱症狀之關係。研究對象為高中職一、二年級學生共653人（男314人、女339人）。資料以結構方程模式（SEM）、淨相關及半淨相關處理。研究結果顯示：第一，本研究所提之因果模式獲得支持，然中介角色只有羞愧感有顯著作用。第二，羞愧感與憂鬱症狀有直接關係，罪惡感必須透過羞愧感才能影響憂鬱症狀。第三，羞愧感排除與罪惡感之相關後，或是排除罪惡感在羞愧感及憂鬱症狀之相關後，羞愧感與憂鬱症狀仍有顯著相關，而罪惡感在以上兩種情形下，跟憂鬱症狀都沒有顯著關係。最後，研究者提出未來研究之建議。

The purpose of this research was to test a causal model between attachment and depression, with guilt and shame as mediating variables. Participants were 653 seventh- and eighth-grade students with 314 males and 339 females. Structural equation modeling and semi-partial and partial correlation were used to analyze the data. Results indicated that the causal model was supported, but only shame played a significant mediating role in the model. Guilt could indirectly affect depression by means of shame as a mediator. Besides, when the shared variance between shame and guilt was controlled, the unique component of shame was still significantly related to depression. Finally, recommendations for the future research were suggested.
