Clinical Trial Summary

To investigate the treatment effect of Stanford Neuromodulation Therapy (SNT) on patients with Non-suicidal Self-injury (NSSI) and the underlying neural mechanism.

Description:

This was a open-label clinical trial to assess the efficacy and underlying neural mechanism of SNT among patients with NSSI.

80 patients with NSSI diagnosed by DSM-5 were recruited from the Second Hospital of Anhui Medical University. After meeting the inclusion criteria and obtaining informed consent, All the participants were randomized (1:1) into two groups: SNT group and rTMS group.

Before the treatment, the Adolescent Non-suicidal Self-injury Assessment Questionnaire (ANSAQ) was obtained by a trained investigator to assess baseline severity. The patients had receiving a battery measure of neuropsychological tests(Hamilton depression/anxiety scale, Health Questionnaire-15) and magnetic resonance imaging (MRI) scan in multimodalities.

For SNT group, the treatment was performed once a day for 5 consecutive days. A Brainsight neuronavigation system was used to position the TMS coil over the individualized stimulation target at each session. Ten sessions of iTBS were delivered daily, for a total of 18,000 pulses per day. Stimulation was delivered at 90% of resting motor threshold (rMT).

For rTMS group, the treatment was also performed once a day for 5 consecutive days. Two sessions of rTMS were delivered daily. Each rTMS session comprised 100 trains of 4s duration at 10 Hz with inter-train intervals of 26 s (i.e., 4000 pulses per session). Stimulation was delivered at 90% of rMT.

In the second day after the last treatment, all the tests and MRI were reassessed. Patients were instructed to focus their answers on the past 1 week.

The clinical symptom and cognition of participants were followed in one week and one month after the last treatment.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Adolescent Non-suicidalself-injury Assessment Questionnaire	The questionnaire consisted of 2 dimensions and 12 items, with 5 options for each item, namely, "none, occasional, sometimes, often and always", and was scored on a 5-point Likert scale from 0 to 4. The score for each item was summed up as the total score of the questionnaire, and the total mean score was divided by the number of items. The total mean score was divided by the number of items, and the higher the total mean score, the more serious the patients' non-suicidal Likert 5 self-injurious behaviors were.	baseline, the second day(immediately after the intervention),the seventh day(immediately after the intervention)
Secondary	Hamilton Depression Rating Scale (HAMD) Score	The HAMD is a clinician-administered depression assessment and consists of 17 items with a total score range from 0 to 54. A higher score indicates a worse outcome.	baseline, the second day(immediately after the intervention),the seventh day(immediately after the intervention)
Secondary	Hamilton Anxiety Scale (HAMA) Score	The HAMA is a 14-item scale to measure the severity of anxiety symptoms, where each item is rated on a scale from 0 to 4. The HAMA total score ranges from 0 to 56, with lower scores indicating less anxiety symptoms.	baseline, the second day(immediately after the intervention),the seventh day(immediately after the intervention)
Secondary	Patient Health Questionnaire-15 (PHQ-15) scale	The PHQ-15 is a 15-item scale to measure the severity of somatic symptoms, where each item is rated on a scale from 0 to 2. The PHQ-15 total score ranges from 0 to 30, with lower scores indicating less somatic symptoms.	baseline, the second day(immediately after the intervention),the seventh day(immediately after the intervention)
