Problematic generalized internet use and insomnia and sleep quality in Portuguese emerging adults

Introduction: The internet use entails various risks, which has led to a growing discussion about its widespread and problematic use. However, the potential repercussions of this use on individuals' insomnia and sleep quality are still not clear. Aims: To explore the relationship between Problematic Generalized Internet Use and Insomnia and Sleep Quality, in a sample of Portuguese emerging adults. Methods: 235 subjects with a mean age of 22.4 (SD = 3.318; range 18- 29) fulfilled a sociodemographic and an internet usage patterns questionnaire, the Generalized Problematic Internet Use Scale, and the Basic Insomnia Symptoms and Sleep Quality Scale. Results: The highest average score on the Generalized Problematic Internet Use scale was obtained in the Mood Regulation dimension. Additionally, 33% reported having poor to very poor sleep quality. Moreover, problematic use was positively associated with poor perceived sleep quality (r =.30**). A significantly difference was found in insomnia and sleep quality between those who were online in leisure more than 4-8 hours (M = 112.23, n = 126), and those who were online less than 2-4 hours. A marginal difference was found between those who were online 1-2 hours before bedtime and those who were online immediately before bedtime. Discussion: results demonstrate the need for better regulation of Internet use, to promote and make individuals aware of a better and healthier quality of sleep and general well-being of individuals.
