Pattern of mobile phone and internet use among 11–15-years-old

Abstract

ObjectiveTo assess the pattern of problematic internet and mobile use in a sample of adolescents. MethodCross-sectional descriptive study in 8 primary and secondary education centres attached to a semi-rural health centre serving 21,000 inhabitants. Two-stage, cluster and systematic sampling, with a final sample size of 446 participants. Sociodemographic variables and data related to the questionnaire for mobile phone-related experiences (CERM) and questionnaire on internet-related experiences (CERI) were collected. Results446 valid surveys were obtained, 228 boys (51.1%) and 218 girls (48.9%) 11–15 years old. A total of 418 (93.7%) had their own mobile. Median mobile usage was 12h on weekdays and 10 at weekends. The most used platforms were WhatsApp (53.6%) and social media (31.4%). Criteria for problematic internet use (CERI>26) were observed in 15.7%, more in 2nd and 3rd ESO. Girls had higher CERI -interpersonal conflict scores (p=.04). Regarding mobile use, girls had higher scores in total CERM (p=.001) and CERM-communicative and emotional use (p=.001). ConclusionsThe results indicate early onset of problems with internet and mobile use, probably related to the accessibility of the new technologies. No parental control was observed. More problematic use of mobile and internet in second and third compulsory secondary education and higher scores in the group of girls related to communication, emotional use and interpersonal conflicts were observed. The findings can help to raise awareness of this problem, detect it early and prevent the effects of addiction to technologies in adolescents.
