Many studies have shown that the use of electronic media is related to sleep disturbance, but few have examined the impact of smartphones. The objective of this study was to assess longitudinally whether acquiring a smartphone had an effect on adolescents’ sleeping duration. The study included 591 adolescents observed at baseline (T0, Spring 2012; mean age 14.3 years, 288 females) and 2 years later (T1). They were divided into owners (those owning a smartphone at T0 and T1; N = 383), new owners (those owning a smartphone at T1 but not at T0; N = 153), and non-owners (those not owning a smartphone at any time-point; N = 55). Groups were compared on sleep duration, sleep problems, and sociodemographic variables. Overall, all three groups decreased their sleeping time between T0 and T1. At T0, owners of a smartphone were found to sleep significantly less than non-owners and new-owners, especially on school days, and to report significantly more sleeping problems. At T1, new-owners and owners showed no differences on sleep duration or sleeping problems.
