What this Trial Is About
Researchers are evaluating whether beta-band transcranial alternating current stimulation tACS can improve impulse control in adolescents with non-suicidal self-injury NSSI and assess its safety. The study aims to find out if this stimulation can reduce the frequency of self-injury and impulsivity scores compared to a sham procedure that mimics stimulation without effective current. Participants will receive two daily sessions of either active beta-band tACS or sham stimulation, spaced at least 4 hours apart, for 7 consecutive days, totaling 14 sessions. The active treatment involves 20 minutes of 20 Hz stimulation delivered to the left dorsolateral prefrontal cortex, while the sham group receives a ramp-up then ramp-down of current to mimic the experience without ongoing stimulation. During the study, participants will undergo assessments including clinical scales for self-injury and impulsivity, behavioral tasks, and eye-tracking tests before and after treatment. Researchers will monitor self-injury episodes and any adverse reactions closely, providing psychological support throughout. The primary outcomes focus on changes in self-injury frequency and impulsivity measured at baseline and after the last treatment day on Day 8.
