This study was conducted to examine the effects of digital addiction on sleep, chronotype, healthy eating self-efficacy and physical activity self-efficacy in adolescents aged 9-18. This study was conducted with 1895 adolescents aged 9-18 studying in schools affiliated with the Ministry of National Education in Elazığ, Turkey. The questionnaire form consisted of demographic data and scales for chronotype, physical activity self-efficacy, healthy eating self-efficacy, sleep disturbance, and digital addiction. Of the adolescents participating in the study, 5.2% were morning people, 46.3% were intermediate, and 48.5% were evening people. Digital addiction was found to affect physical activity self-efficacy (p <0.001) and healthy eating self-efficacy (p <0.001). The introverted factors subscale of digital addiction was found to have a significant and positive effect on chronotype levels (p <0.01). The digital addiction scale subscales were found to have effects on sleep initiation and maintenance problems (p <0.001), sleep-disordered breathing (p <0.001), arousal reaction disorders (p <0.001), sleep-wake transition disorders (p <0.001), and excessive sleepiness disorders (p <0.001). Consequently, increased digital addiction had a negative impact on participants’ physical activity self-efficacy, healthy eating self-efficacy, and sleep disorders.}, number={2}, publisher={Bingöl Üniversitesi}
