| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Yale global tic severity scale | baseline assessment (T0) | Tic symptom severity is estimated by Yale Global Tic Severity Scale Total Tic score. The YGTSS is a clinician-rated scale used to assess tic severity over the prior week. It includes a checklist of motor and vocal tics followed by an assessment of the number, frequency, intensity, complexity, and inference of motor tics and phonic tics-scored separately. Each of these dimensions is scored on a 0 to 5 scale. The YGTSS provides three tic severity scores: Total Motor (0 to 25); Total Phonic (0 to 25) and the combined Total Tic Severity Score (0 to 50), as well as a separate Impairment dimension scored from0 to 50. The Total Tic Score (YGTSS-TTS) was used in these analyses.Lower scores indicate improvement and higher scores indicate worsening. |
| Primary | Yale global tic severity scale | assessment after 4 weeks of treatment (T1) | Tic symptom severity is estimated by Yale Global Tic Severity Scale Total Tic score. The YGTSS is a clinician-rated scale used to assess tic severity over the prior week. It includes a checklist of motor and vocal tics followed by an assessment of the number, frequency, intensity, complexity, and inference of motor tics and phonic tics-scored separately.

| Primary | Yale global tic severity scale | assessment after 8 weeks of treatment (T2) | Tic symptom severity is estimated by Yale Global Tic Severity Scale Total Tic score. The YGTSS is a clinician-rated scale used to assess tic severity over the prior week. It includes a checklist of motor and vocal tics followed by an assessment of the number, frequency, intensity, complexity, and inference of motor tics and phonic tics-scored separately. Each of these dimensions is scored on a 0 to 5 scale.

| Primary | Wisconsin Card Sorting Test | baseline assessment (T0) | The participants were asked to sort 64 cards to match either color (red, blue, yellow, or green), form (crosses, circles, triangles, or stars), or number of figures (one, two, three, four). During the task, the sorting rule changed discreetly from color to form or number of figures without the participants being informed. The participants had to shift sets accordingly and sort cards following the new sorting rule. Set shifting difficulties were indicated by preservative errors; thus, higher scores on this test represent worse performance. |
| Primary | Wisconsin Card Sorting Test | assessment after 4 weeks of treatment (T1) | The participants were asked to sort 64 cards to match either color (red, blue, yellow, or green), form (crosses, circles, triangles, or stars), or number of figures (one, two, three, four). During the task, the sorting rule changed discreetly from color to form or number of figures without the participants being informed.

| Secondary | Color-word Stroop task | It's a repeated measurement variable，baseline assessment (T0), assessment after 4 weeks of treatment (T1), assessment after 8 weeks of treatment (T2), and 3-month follow-up after completion of treatment (T3) | The Stroop task requires participants to name the ink color of a series of color words. In the congruent condition, the color name corresponds exactly to the color of each letter; in the incongruent condition, the printed word and the actual color of each letters are different. When subjects are required to report the ink color of the word, greater difficulty is experienced when they are in the incongruent condition. This difficulty can be measured by the increase in the amount of time required to complete the task (the Stroop interference effect). The measure of executive ability is the relative response delay in the Stroop interference condition as measured by response time (RT) in the incongruent condition minus RT in the neutral condition. |
| Secondary | The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) | It's a repeated measurement variable，baseline assessment (T0), assessment after 4 weeks of treatment (T1), assessment after 8 weeks of treatment (T2), and 3-month follow-up after completion of treatment (T3) | The CY-BOCS evaluates the severity of obsessions and compulsions, using ten items across five dimensions (time occupied by symptoms, interference, distress, resistance and degree of control over symptoms). The total severity score can range from 0 to 40. CY-BOCS total scores in the range of 14-24 are considered moderate, 25-30 moderate-severe and over 30 severe |
