Problematic Internet use (PIU), a common phenomenon, has negative effects on adolescents, especially during the COVID-19 pandemic. Adolescents with PIU pose great challenges to parenting. However, little is known about the mediating mechanisms underlying this relationship. The study examines the chain mediating roles of parenting stress and parental expectations between PIU and parental involvement across early, middle, and late adolescence. Families (N = 1206) that included fathers, mothers, and adolescents (48.9% females, Mage  = 13.86 ± 2.48) participated in the study. Adolescents provided a rating of PIU, and fathers and mothers reported their own parenting stress, parental expectations, and parental involvement. The results showed that paternal parenting stress and then expectations mediated the association between PIU and paternal involvement, and maternal parenting stress and then expectations mediated the association between PIU and maternal involvement, indicating a spillover effect. By contrast, the crossover effect was established only in that maternal parenting stress was negatively related to paternal expectations in middle adolescents. Moreover, maternal expectations showed the strongest association with maternal involvement in middle adolescents, whereas paternal expectations were most associated with paternal involvement in late adolescents. These findings underline the necessity of understanding parenting by assessing adolescent developmental stages and paternal and maternal parenting separately. Furthermore, the mediators of parenting stress and parental expectations can be the focus on facilitating parental involvement; the effect of maternal parenting stress on paternal expectations may suggest that intervention programs for fathers should consider more contextual factors.
