Researchers will compare three groups-active tDCS, sham tDCS (a simulation where stimulation is stopped after the first seconds), and a control group (no stimulation)-to see whether changes are due to tDCS rather than placebo effects or time.\n\nParticipants will:\n\n* Complete an initial screening and baseline questionnaires (a sociodemographic questionnaire and the IAT).\n* Be randomly assigned to one of three groups: active tDCS, sham tDCS, or control (no stimulation).\n* Complete the IAT again after the intervention and again about 5 weeks later (follow-up), along with questions about social media use habits.\n\nDuring intervention, participants in active tDCS and sham tDCS will:\n\n* Attend 10 sessions over 2 consecutive weeks (Monday-Friday), with each session lasting about 30 minutes; mobile phone use is not allowed during sessions.\n* Rate craving on a Visual Analogue Scale (VAS) at the start and end of each session.\n\nThis study will be conducted with university students in the Greater Lisbon area and will follow double-blind procedures for the active vs sham conditions (participants and researchers will not know the assigned condition until the end of the study).",[27,28,29,30],"Social Media Addiction","Craving to Use Social Media","Craving","Internet Addiction",[32,33,34,29,35,36,37],"Social media addiction","Internet addiction","Digital addiction","Transcranial direct current stimulation","tDCS","Non-invasive neuromodulation","RECRUITING","2026-02-18",{"date":41,"type":42},"2026-02-20","ACTUAL",{"date":44,"type":21},"2026-03",{"date":46,"type":21},"2026-09",{"name":48,"class":49},"Egas Moniz - Cooperativa de Ensino Superior, CRL","OTHER"]
