隨著智慧型手機與網路的普及，青少年的生活深受數位科技影響，許多青少年出現社交剝奪、睡眠不足、注意力分散與上癮等問題，其中「網路成癮」已成為影響青少年心理健康的重要因素。在此背景下，父母如何引導、規範與參與子女的網路使用，也就是「數位教養」，成為影響青少年社會心理發展的關鍵因素。因此，本研究旨在探討父母數位教養風格對青少年憂鬱情緒之影響，並檢驗網路成癮在其中的中介角色。

　　本研究使用「臺灣數位世代青少年的成長歷程追蹤研究（TIGPS）」第一波與第二波資料，以學生知覺之父母數位教養為自變項，透過潛在剖面分析 辨識數位教養風格，後續透過迴歸分析與因果中介分析，檢驗網路成癮在數位教養風格與青少年憂鬱情緒間的中介效果。

　　潛在剖面分析的結果辨識出五種數位教養風格，不同教養風格在網路成癮與憂鬱情緒上具有顯著差異，其中低壓陪伴型青少年整體表現較佳，而嚴格規範型相對較差。接著，因果中介分析顯示，網路成癮具有部分中介效果，約三至四成的影響可由中介路徑解釋，顯示父母數位教養不僅會直接影響憂鬱情緒，也會透過影響青少年網路成癮情形，對憂鬱情緒產生間接作用。

　　整體而言，本研究指出數位教養並非單一面向的教養策略，如：控制、放任、支持，而是透過不同教養面向間交互搭配、組合運用，呈現出多元的數位教養風格；適度支持與陪伴有助於降低網路成癮與憂鬱風險，而過度控制、限制或忽視則可能帶來負面影響。

論文外文摘要： With the widespread use of smartphones and the Internet, adolescents’ daily lives have been profoundly influenced by digital technologies. Many adolescents experience problems such as social deprivation, insufficient sleep, distraction, and addiction, among which Internet addiction has become an important factor affecting adolescent mental health. In this context, how parents guide, regulate, and participate in their children’s Internet use, namely, digital parenting, has become a key factor in adolescents’ social and psychological development. Therefore, this study aims to examine the effects of parental digital parenting styles on adolescent depressive symptoms and to investigate the mediating role of Internet addiction.

This study used data from the first and second waves of the Taiwan Internet Generation and Parenting Study (TIGPS). Adolescents’ perceptions of parental digital parenting were used as the independent variable, and latent profile analysis was conducted to identify distinct digital parenting styles. Regression analysis and causal mediation analysis were subsequently employed to examine the mediating effect of Internet addiction on the relationship between digital parenting styles and adolescent depressive symptoms.

The latent profile analysis identified five distinct digital parenting styles. Significant differences were found across parenting styles in both Internet addiction and depressive symptoms. Overall, adolescents in the low-pressure companionship group demonstrated more favorable outcomes, whereas those in the strict regulation group showed relatively less favorable outcomes. Furthermore, the causal mediation analysis indicated that Internet addiction partially mediated the relationship between digital parenting styles and depressive symptoms, with approximately 30% to 40% of the total effect being explained by the mediating pathway. These findings suggest that parental digital parenting not only has a direct effect on adolescent depressive symptoms but also indirectly affects depressive symptoms by influencing adolescents’ Internet addiction.

Overall, this study demonstrates that digital parenting is not a unidimensional parenting strategy characterized solely by control, permissiveness, or support. Rather, different dimensions of parenting interact and combine to form diverse digital parenting styles. Appropriate support and companionship may help reduce the risks of Internet addiction and depressive symptoms, whereas excessive control, restriction, or neglect may have negative consequences.
