本研究主要探討家庭支持、不當對待行為、社會參與對青少年幸福感的影響，並比較性別上的差異。研究資料取自「2019年臺北市兒童及少年生活狀況調查」的原始資料，以家庭支持為自變項、不當對待行為和社會參與為中介變項、幸福感為依變項，並以性別為調節變項。研究結果顯示，青少年的幸福感會受到家庭支持和社會參與的影響，但不會受到不當對待行為的影響，而且此一模型在不同性別間具有恆等性，研究者據此提出結論和建議。

This study aimed to explore the effect of family support, youth maltreatment, and social participation on adolescents' well-being with gender differences. The research used the data from the Taipei City Children and Adolescents' Living Conditions Survey in 2019 for analysis, with family support as the independent variable, youth mistreatment and social participation as the mediating variables, adolescents' well-being as the dependent variable, and gender as the moderating variable. Results indicate that family support and social participation affect adolescents' well-being; however, youth maltreatment has no effect on their well-being. There are no gender differences within this model. Based on the results, conclusions and suggestions were made.
