This research aims to explore the relationship between different domains of life satisfaction (LS), time spent in different activities using digital technology (DT) and negative online experiences in children aged 9 to 12 years in Croatia. Participants were 168 elementary school pupils who filled out a paper questionnaire providing data on LS, different DT activities and negative online experiences. Results point to gender differences for engagement in some types of DT activities and negative online experiences. Furthermore, while there are some aspects of DT use that can to some extent be related to lower LS in certain domains (e.g., time spent watching YouTube and using social networks), there are some aspects of this use that can be viewed as beneficial for LS (e.g., time spent corresponding with friends). The suggested model for predicting LS based on different activities using DT and negative online experiences was statistically insignificant.
