研究目的：探討高中職青少年不同生活事件類型對於人格特質與行為問題的中介作用，及不同憂鬱狀態在前述機制中之修飾作用。
研究方法：本研究為以學校為基礎(school-based)的二波段追蹤研究 (2-wave panel study)。研究以多階段抽樣方式(multistage sampling)選取樣本，總計納入354名高中職學生進行分析。生活事件對人格特質與行為問題之中介效果以Sobel test進行檢驗，95%信賴區間以bootstrap方式進行估計；並以結構方程式(Structural Equation Modeling)分析憂鬱狀態對前述關係之修飾作用。
研究結果：不同人格特質為行為問題與負向衍生事件之預測變項。負向生活事件在許多人格特質與行為問題之間產生中介作用，並且青少年憂鬱狀態對大多人格-負向事件-行為問題具有修飾效果，但不影響神經質-負向衍生事件-外化行為問題及神經質-負向衍生事件-全行為的路徑。
結論：青少年不論有無憂鬱，神經質人格明顯者，與各種行為問題均有相關，其中外化行為問題可為負向衍生事件所中介，表示神經質人格與負向衍生事件為預防與介入青少年行為問題之關鍵。心理衛生或學校輔導相關單位應特別注意有此情形之青少年，早期預防青少年行為問題的產生 。
Objectives: The aim of this study is examining the mediating effect of life events and the moderating effect of depressive symptoms on the relationship between personality traits and behavioral problems in adolescents. Methods: There are 354 subjects ascertained by using multistage sampling in a school-based 2-wave panel study. The mediating effect of life events on the relationship between personality traits and behavioral problems was examined by Sobel test, plus with its 95% confidence interval estimated by bootstrapping method. The moderating effect of depressive symptoms on the personality-life events-behavioral problems mechanism was analyzed by Structural Equation Modeling. Results: Personality traits predict behavioral problems and life events. Negative life events were mediator on the relationship between personality traits and behavioral problems in depressive and non-depressive adolescent, and the moderating effects of depressive symptoms on the mechanism of neuroticism-negative life events-behavioral problems were also confirmed. Conclusions: The results indicated that negative dependent life events were mediator between neuroticism and externalizing problems and total problems among adolescents, with or without depression. Prevention or intervention strategies for behavioral problems may focus on adolescents with high neuroticism and recent negative dependent life events.
