People using mobile phones International estimates of the prevalence of forms of technology overuse have varied considerably, with marked variations by nation and increases over time. Prevalence of mobile phone overuse depends largely on definition and thus the scales<unk> d to quantify a subject's behaviors. Two main scales are in<unk> , the 20-item self-reported Problematic<unk>  of Mobile Phones (PUMP) scale, and the Mobile Phone Problem<unk>  Scale (MPPUS), which have been<unk> d both with adult and adolescent populations. There are variations in the age, gender, and percentage of the population affected problematically according to the scales and definitions<unk> d. The prevalence among British adolescents aged 11–14 was 10%. In India, addiction is stated at 39-44% for this age group. Under different diagnostic criteria, the estimated prevalence ranges from 0 to 38%, with self-attribution of mobile phone addiction exceeding the prevalence estimated in the studies themselves. The prevalence of the related problem of Internet addiction was 4.9-10.7% in Korea, and is now regarded as a serious public health issue. A questionnaire survey in Korea also found that these teenagers are twice as likely to admit that they are "mobile phone addicted" as adults. For most teenagers,<unk>  communication is what they think is an important way to maintain social relationships and has become an important part of their lives. Additional scales<unk> d to measure<unk>  addictions are the Korean Scale for Internet Addiction for adolescents (K-scale), the<unk>  Addiction Scale (SAS-SV), and the<unk>  Addiction Proneness Scale (SAPS). These implicit tests were validated as means of measuring<unk>  and internet addiction in children and adolescents in a study conducted by Daeyoung Roh, Soo-Young Bhang, Jung-Seok Choi, Yong Sil Kweon, Sang-Kyu Lee and Marc N. Potenza. Behaviors associated with mobile-phone addiction differ between genders. Older people are less likely to develop addictive mobile phone behavior because of different social usage, stress, and greater self-regulation. At the same time, the study by media regulator Ofcom has shown that 50% of 10-year-olds in the UK owned a<unk>  in 2019. These children who grow with gadgets in their hands are more prone to mobile phone addiction, since their online and offline worlds merge into a single whole.
