An independent researcher who will not be involved in recruitment, intervention delivery, or outcome assessment will generate the random allocation sequence before allocation. Assignments will be concealed in sequentially numbered, opaque, sealed envelopes, which will be opened in order after baseline assessment to reveal each participant’s allocation. N/A Conduct disorder. Intervention group 1: Participants will receive supervised virtual reality–based martial arts training using Pico 4 Enterprise headsets at a pediatric rehabilitation center. The program will include 21 sessions over 7 weeks, three sessions per week, lasting 30–50 minutes each. Sessions will comprise 5–10 minutes of warm-up, 20–30 minutes of striking, footwork, balance, coordination, and progressively complex movement sequences, followed by 5–10 minutes of cool-down and reflection. Two certified martial arts instructors will supervise moderate-intensity training and monitor discomfort. Virtual reality exposure will be paused or stopped if moderate or severe symptoms occur.. Yes - There is a plan to make this available What will be shared: De-identified participant-level data underlying the reported results will be shared, including group allocation and executive-function scores at baseline, post-intervention, and 30-day follow-up. Names, contact details, and other identifying information will be removed. When: Data will be available upon reasonable request from six months after publication of the main study results for a period of five years. To whom: Qualified researchers from academic, scientific, or industry institutions will be eligible to request access. Access will require an approved research proposal and a signed data-use agreement protecting participant confidentiality. Conditions: Data will be used only for approved secondary analyses, verification of findings, or meta-analyses. Requests will specify the research aim, required variables, and analysis plan. Users will maintain secure storage, make no attempt to identify participants, and neither redistribute the data nor use them beyond the approved purpose. Where to obtain: Requests will be submitted by email to Fatemeh Mirzaei at solalll.19966@gmail.com. Applicants will provide their name, institutional affiliation, research proposal, required data, and analysis plan How to obtain: Applicants will email Fatemeh Mirzaei at solalll.19966@gmail.com, providing their institutional affiliation, research aim, required data, and analysis plan. Requests will be reviewed within four weeks. Following approval and signing of a data-use agreement, de-identified data will be transferred securely within two weeks.

The Behavior Regulation Index (BRI) T-score will be assessed using the BRIEF-2 Parent Form. Timepoint: Measurements will be taken at baseline before the intervention, immediately after the 7-week intervention, and 30 days after its completion. Method of measurement: The Parent Form of the Behavior Rating Inventory of Executive Function, Second Edition, will be completed by a parent or legal guardian to obtain the standardized score for the Behavior Regulation Index. university of tehran Approved 2026-05-03 Research Ethics Committee of the Sport Sciences Research Institute (SSRI) No. 3, Fifth Alley (Sedrus), Mir Emad St., Shahid Motahari St., Abbas Abad–Andisheh Neighborhood Tehran Tehran Iran (Islamic Republic of)
