Dieta mediática, autocontrol digital y procrastinación en universitarios

This research seeks to understand how social media use influences self-control and academic procrastination practices. To this end, a structured questionnaire was administered to students from two Spanish universities. At the same time, a focus group was formed with seven students from the Universidad de Valladolid to explore perceptions and meanings in greater depth. The results show a cross-sectional predominance of social media (Instagram and TikTok) as the main sources of information and leisure, accompanied by persistent difficulties in digital self-control. Academic procrastination is reported in more than 60% of students, linked to excessive use of devices, with effects of stress and temporal disorganization. Likewise, greater vulnerability to misinformation is observed in younger students. These findings confirm that media consumption has an impact on both academic performance and student well-being, leading to a series of recommendations for education and communication.
