Smartphone dependence can be measured through questionnaires that evaluate time of use, feelings associated with the absence of the device, and habits related to the use of this technology. Unlike gambling addiction, smartphone addiction has not yet been classified as a disease within the areas of medical knowledge, but several studies show harm to individuals who develop this addiction, such as sleep, mood, and impulsive disorders. Purpose: We aim to find out the prevalence of smartphone addiction and determine its epidemiology among university students in the city of Maceió. Methods: The smartphone dependency scale was applied among undergraduates, validated by the author Julia Khoury, from the SPAI (Smartphone Addiction Inventory) questionnaire, using the cutoff point of 9 positive answers out of 26 questions. Results: In this research, a prevalence of dependence of 31.85% was found, without gender difference, with higher incidence among individuals under 40 years old. Conclusions: Given the high proportion of smartphone addicts and the consequences of this addiction, it is appropriate to discuss strategies to promote health and assist those affected.
