A Study of the Relationship Between Peer Interaction and Delinquency of Junior High Student

本文目的在於同時考慮吸菸、喝酒、吸毒與蹺課之間的互相影響關係，並以遞延時間變數解決同儕互動所產生的內生性問題。採用中央研究院社會科學研究所執行之「青少年個人生活學業評量」問卷調查資料。使用兩階段迴歸分析方式，以Multivariate Probit Model得到結果。結果發現蹺課會正向誘發吸菸、喝酒與吸毒的機率，吸菸會正向誘發喝酒、吸毒與蹺課的機率，且國三所產生的偏差行為相互影響的顯著行為相對國二多出許多。表示國二時期出現了蹺課行為，接下來就會誘發其他的偏差行為的產生，且到了國三更為嚴重。就同儕方面，同儕的偏差行為影響，國二時統計上的結果無顯著現象是由於學生的社交網絡尚未定型。然而到了國三社交網絡大致上已經定型，同儕行為的影響變得非常顯著。Many years of concerted policy effort in young people from experimenting with smoking, alcohol ,illicit-drug use and truant.
