This article examines the relationship between the frequency and intensity of digital technology use and mental health indicators—anxiety, depression, and stress—among adolescents in Uzbekistan. It is based on a 2022 national school survey conducted with UNICEF and Uzbek ministries, covering 22,854 respondents nationwide. Results show that excessive device use (more than five hours a day) is associated with higher anxiety and depressive symptoms. Focus groups reveal a gap between parents' perceptions and adolescents' actual online behavior. The findings underscore the need for comprehensive digital well-being programs and digital hygiene education in schools.
