本研究主要依據社會學習理論與理性選擇理論之觀點,探討有毒的男子氣概、暴力行為自我效能、暴力行為效益評估對青少年暴力行為的影響。本研究之資料係以自陳問卷調查法蒐集取得,研究對象為彰化縣333名國小高年級男性學生,再將受測者資料透過描述性統計、相關分析及巢式迴歸模型分析加以處理與分析。本研究結果發現鬥毆性暴力行為自我效能及威嚇性暴力行為自我效能對青少年暴力行為具正向影響效果,且暴力行為效益評估越高時,亦會增加青少年暴力行為的發生。最後,本研究根據研究結果進行討論並提出建議,作為政府、學校、教師、家長、社福單位以及未來研究之參考。 This study is mainly based on the perspectives of social learning theory and rational choice theory to explore the impact of toxic masculinity, violent self-efficacy, and evaluation of the benefits of violent behavior on violence among elementary school seniors. The data of this study was collected through self-reported questionnaires from 333 male students in their senior year of elementary school in Changhua County. The collected data was then processed and analyzed through descriptive statistics, correlation analysis, and nested regression models. The results of this study found that both fighting violent self-efficacy and intimidating violent self-efficacy have a positive impact on violence among adolescents, and the higher the evaluation of the benefits of violent behavior, the more likely violence among adolescents will occur. Finally, based on the research results, this study provides suggestions for the government, schools, teachers, parents, social welfare agencies, and future research as a reference.
