Nomophobia and smartphone addiction: do the variables age and sex explain this relationship?

Abstract This study aimed to identify the extent nomophobia explains smartphone addiction, controlling for age and gender effects. Participants were 316 people from the 22 Brazilian states (Mage = 28.1 years), most from Paraíba (38.9%) and Piauí (16.5%), equally distributed between genders. They answered the Nomophobia Questionnaire, the Smartphone Addition Scale and demographic questions. The results demonstrate that the factors of the nomophobia measure explained smartphone addiction, indicating that more nomophobic behavior equates to increased smartphone addiction, especially in the younger participants, there was no difference regarding gender. These findings are discussed according to the literature on adherence to new technologies, revealing the current problem of smartphone addiction in young people.
