With the ubiquity of digital technology in the daily lives of children, issues have been raised regarding its potential perils on children's development. Parental mediation may mitigate these potential negative effects. However, parental mediation and its impact on children's screentime have been hardly explored in the Philippine setting, highlighting the need to examine the said topic. Thus, this study aimed to investigate the impact of parental mediation strategies on the children's recreational screentime according to three age groups: preschoolers (4-6 years), younger (7-9 years) and older (10-12 years) elementary graders. 172 parents, with children ages 4-12 years, answered an online survey on their children's media practices and the mediation strategies they use. Results revealed that the mean screentime for preschoolers and younger elementary graders were significantly lower compared to older elementary graders but there was no significant difference between mean screentime of preschoolers and younger elementary graders. Regression analysis indicated that diversionary mediation was a statistically significant predictor of screentime (i.e., children whose parents use this strategy have significantly lower screentime compared to parents who do not use it). Results also showed that there was a statistically significant interaction between age group (older elementary graders versus preschoolers) and absence of co-use mediation, indicating that the decrease in screentime associated with non-practice of co-use was less pronounced for older elementary graders than for preschoolers, which in turn, may suggest that co-use mediation is more likely used with younger than older children. This study highlights the crucial role of parents and caregivers in regulating children's screen media use and the value of employing more than one parental mediation strategies, especially more contemporary ones such as diversionary mediation.
