Intervention Effect of High-Definition Transcranial Alternating Current Stimulation (HD-tACS) on Non-suicidal Self-injury (NSSI)
Study Overview
Status
Detailed Description
Forty patients with Non-suicidal Self-injury (NSSI) diagnosed by DSM-5 were recruited from the Second Affiliated Hospital of Anhui Medical University. All participants underwent a structured interview and routine laboratory examination before and after receiving high-definition transcranial alternating current stimulation (HD-tACS) treatment after meeting the inclusion criteria and obtaining informed consent. Each participant will complete the clinical evaluation, magnetic resonance imaging (MRI), and HD-tACS treatment conducted by trained researchers at the Second Affiliated Hospital of Anhui Medical University. All the participants were randomized (1:1) to receive an "active HD-tACS" or "sham HD-tACS" treatment protocol. tACS: the central electrode was placed over F3 with return electrodes placed at Fp1, Fz, F7 and C3. Fourteen 2-mA sessions (ramp-up and ramp-down periods of 15 and 15 seconds, respectively) were applied for 20 minutes per session, twice daily over 7 consecutive days, and the stimulus frequency was set as individual alpha frequency (IAF). Sham HD-tACS was delivered using the same protocol and current intensity, but the period of active stimulation was only during the ramp-up and ramp-down periods of 15 and 15 seconds.
Before and after the treatments, the patients received a battery measure of neuropsychological tests, and MRI scans in multimodalities. The neuropsychological assessment included the Ottawa Self-injury Inventory (OSI), the Adolescent Non-suicidal Self-injury Assessment Questionnaire (ANSAQ), the Hamilton Depression Rating Scale (HAMD), the Hamilton Anxiety Rating Scale (HAMA), and Patient Health Questionnaire-15 (PHQ-15) etc.Multimodal MRI includes 3D-T1, rs-fMRI, and DTI. The symptoms of the patients were followed up one and two months after the end of treatments.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: real stimulation
The central electrode was placed over F3, with return electrodes at Fp1, Fz, F7 and C3.
Fourteen 2-mA sessions (ramp-up and ramp-down periods of 15 and 15 seconds, respectively) were applied for 20 minutes per session, twice daily over 7 consecutive days, and the stimulus frequency was set as IAF.
|
tACS is described as a non-invasive form of brain stimulation that uses a low-intensity, alternating current applied directly to the head through scalp electrodes.
|
Sham Comparator: sham stimulation
In the sham condition, tACS was delivered only during the ramp-up and ramp-down periods (15 and 15 s); no current was delivered during the 20-minute intervention.
Participants will receive sham tACS twice daily for two weeks.
|
In the sham condition, tACS was delivered only during the ramp-up and ramp-down periods (15s and 15s); no current was delivered during the 20-minute intervention.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in the number, frequency, and impulsivity of self-injurious behaviors
Time Frame: baseline and immediately after the intervention
|
Adolescent Non-suicidal self-injury Assessment 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 and immediately after the intervention
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Hamilton Depression Rating Scale (HAMD) Score
Time Frame: baseline and immediately after the intervention
|
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 and immediately after the intervention
|
Change in Hamilton Anxiety Scale (HAMA) Score
Time Frame: baseline and immediately after the intervention
|
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 and immediately after the intervention
|
Change in Patient Health Questionnaire-15 (PHQ-15) Score
Time Frame: baseline and immediately after the intervention
|
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.
