Adolescents spend a large amount of time on screens, especially smartphones. Excessive screen use has been linked to health problems such as poor sleep, reduced physical activity, academic difficulties, and mental health issues. Primary care professionals often lack practical tools to help young people address this problem.
This study aims to evaluate whether a dedicated medical consultation (DC), using a structured interview guide and a screening questionnaire (e-KID), can help adolescents aged 12 to 17 reduce and improve their screen use. When excessive screen exposure is identified, adolescents are offered a personalized consultation with a healthcare professional. Together, they discuss screen habits, health impacts, and set achievable goals to change usage patterns.
The investigator hypothesizes that adolescents who receive this dedicated consultation by healthcare providers trained with a specific grid will better reduce their smartphone screen time and adopt healthier screen use habits compared to those receiving usual care.

Change in time spent on the smartphone, measured in hours and minutes (recorded via screenshots), between the baseline visit and one month later, over a period of 7 consecutive days and outside school holidays, in both groups.
Change in time spent on smartphone use, measured in hours and minutes, assessed via participant screenshots of screen-time statistics. Smartphone use will be recorded over 7 consecutive consecutive days at each time point (baseline and 1 month), excluding school holidays, in both intervention and control groups.
