While the BootStRaP project has not yet reached the stage of data analysis, our work to date represents a significant advancement beyond the current state of the art in understanding and addressing Problematic Usage of the Internet (PUI). Through the development of our digital screening and assessment platform, we have established an innovative, multimodal approach that integrates passive digital phenotyping, mobile sensing, and cognitive testing to objectively measure behavioural patterns linked to PUI. This marks a crucial departure from traditional self-report methods, offering a more reliable and dynamic means of assessing risk and resilience factors.
Our large-scale, cross-national recruitment of adolescents aged 12 to 16 from nine countries (UK, France, Germany, the Netherlands, Lithuania, Hungary, Switzerland, Spain, and Portugal) is another major advancement. This diverse, multi-site approach allows for a systematic, longitudinal examination of PUI across different cultural and socio-economic contexts, enhancing the generalizability of our findings.
Additionally, BootStRaP is set to establish a new benchmark in early detection by refining and validating the most effective screening tools for PUI. By comparing different self-report measures and integrating them with objective digital assessments, we are working towards a gold-standard methodology for identifying risk at an individual level. This personalized approach has not been previously implemented at this scale.
Furthermore, BootStRaP’s digital self-management interventions, currently under development, will be the first to systematically test the effectiveness of cognitive-behavioural strategies tailored to key mechanisms of PUI, such as affect regulation and inhibitory control. By co-designing these interventions with stakeholders, including young advisors and educators, we aim to maximize engagement, effectiveness, and scalability.
As data collection progresses, BootStRaP will continue to push the boundaries of knowledge in this field, ultimately delivering a transformative impact on adolescent digital well-being, intervention strategies, and policy development.
