本研究探討休閒時光運用與對於青少年網路不當行為和網路成癮的影響，以父母的正向支持和負向支持為自變項，網路不當行為與網路成癮為依變項，休閒時光（睡眠時間、休閒活動時間、運動天數、與父母聊天時間、參與志工服務時間）運用為中介變項，並以性別、學生身分為調節變項。研究資料取自2021年新北市兒童及少年生活狀況與福利需求調查，以結構方程模型進行資料分析。研究結果顯示，青少年的網路不當行為主要受到父母支持、睡眠時間、休閒活動時間、運動天數的影響，網路成癮則是受到父母支持、睡眠時間、休閒活動時間、運動天數、與父母聊天時間、志工服務時間的影響，研究者據此提出結論與建議。

This study examines the relationships among youths' leisure time use and its influence on online behavior and Internet addiction. Positive and negative support from parents were used as independent variables, adolescent online behavior and Internet addiction as dependent variables, youth's leisure time use as a mediator, and gender and student status were moderators. Mediators of the youth's leisure time included their amount of sleep, time spent on leisure activities, exercise days, time spent conversing with parents, and time spent on volunteer activities. This research used raw data on adolescents extracted from the 1,952 surveys of the Children and Adolescents' Living Conditions and Welfare Needs Survey collected by the New Taipei City government in 2021. The analysis was conducted using a Structural Equation Model. The result shows adolescent online behavior is largely affected by both positive and negative parental support, amount of sleep, time spent on leisure activities, and days of exercise, while Internet addiction is affected by both positive and negative parental support, amount of sleep, time spent on leisure activities, time spent talking to parents, and time spent on volunteer activities. The researchers provide conclusions and give suggestions accordingly.
