Concerning technological trends, it stands out that 96.1% of participants (teenage students) already owned a smartphone. Among them, about one-third stated its use was somewhat restricted (e.g., limited functionality by an app) or supervised by parents (e.g., only allowed to use it at home). On the other hand, approximately two-thirds of mobile phone owners stated a relatively free right to use their devices. Approximately 70% of participants declared a greatly frequent social network use, while only about 10% accessed them less than once a week (including teenagers not using them at all).
