About this trial
In order to assess the clinical efficacy of triple-daily 15mA-tACS stimulation by comparing the effects of active and sham tACS interventions on driving improvements in adolescent Nonsuicidal Self-Injury(NSSI), participants will be randomly assigned to either the active or sham tACS group. This trial consists of a 2-week intensified intervention phase (40 sessions), followed by a 4-week observation period. The key hypothesis is that triple-daily 15mA-tACS stimulation will enhance clinical recovery compared to sham stimulation.
