Measuring screen time among adolescents: test–retest reliability of HBSC questionnaire items across two countries
The screen-time items tested in this study showed acceptable test-retest reliability across countries, age groups, and sexes, particularly for gaming and social networking. These findings support their use in global adolescent health surveillance, while highlighting the need for refinement of less stable domains such as video watching and internet browsing. Given that samples were not nationally representative, findings should be interpreted within these specific contexts. Future research should enhance measurement precision and inform public health efforts to monitor and address screen-time related health risks.
