About this trial
This randomized, double-blinded, placebo-controlled clinical trial aims to evaluate the efficacy and safety of naltrexone in reducing nonsuicidal self-injurious behavior among individuals with nonsuicidal self-injury. Participants will be randomly assigned to receive either naltrexone plus treatment as usual or placebo plus treatment as usual for 6 weeks.
The primary objective is to determine whether naltrexone reduces the frequency of nonsuicidal self-injurious behavior compared with placebo. Secondary objectives include evaluating changes in clinical severity, suicidal ideation, self-injury-related urges, ecological momentary assessment measures, and safety outcomes.
