本研究主要依據理性選擇理論與一般化犯罪理論之觀點，探討偏差行為之傷害及效益評估、低自我控制與國中生偏差行為之關聯性。利用問卷調查法進行研究，以雲、嘉地區12所學校之871名國中學生為研究對象，經資料整理後以描述統計、積差相關與巢氏迴歸分析法等統計方法，進行資料處理與統計分析。研究結果發現：（1）國中生對偏差行為之傷害評估對偏差行為具有抑制性影響力。（2）國中生對偏差行為之心理效益評估對偏差行為發生具有響力。（3）國中生之低自我控制程度影響其偏差行為之發生情形。最後，本研究根據研究結果進行討論，並提出對家長、教師與未來相關研究之建議。 This study, based on Rational Choice Theory and General Theory of Crime, aimed to investigate the relations among the evaluation of the costs and benefits of deviant behavior , low self-control, and junior high school students' delinquency.
