<p>Parental phubbing refers to a phenomenon in which parents are distracted by their smartphones when they interact with their children. It has become a common concern and linked to adolescents’ Internet addiction. However, existing studies have insufficient understanding of the mechanism of parental phubbing and adolescent Internet addiction, and have not distinguished between the father-child system and the mother-child system, nor explored differences in the gender of children. This study aims to investigate the relationship between parental phubbing and adolescent Internet addiction through sequential mediation modeling, multi-group analysis, and network analysis. Self-reported data were collected from 2,082 adolescents (M_age = 11.03 years, SD = 1.13; 47.5% girls). Father and mother phubbing were significantly and positively associated with adolescent Internet addiction, with indirect effects mediated through father involvement, mother involvement, and parental internet supervision (Father: proportion of total effect, 37.77%; Mother: proportion of total effect, 30.92%). Significantly, our study discovered that the influence of mother phubbing on adolescent Internet addiction varies according to the adolescent’s gender, a pattern not observed with father phubbing. The network analysis results suggest that parental involvement and parental internet supervision act as mediators in the relationship between parental phubbing and adolescent IA through four specific nodes: PIS5 (My parents are aware of the friends I have met or regularly contact online), PIS10 (My parents are strict about me making or contacting friends online), PIS2 (My parents know exactly how many times I go online in a week), PI1 (Dad/Mom urges me to do my homework). These findings help us understand how parental phubbing affects adolescent Internet addiction and its underlying mechanisms, especially the important role of parental Internet supervision.</p>
