Primary | Symptom improvement assessed by the Yale-Brown Obsessive Compulsive Scale | The Yale-Brown Obsessive Compulsive Scale is a test to rate the severity of obsessive-compulsive disorder symptoms, which measures obsessions separately from compulsions. The scale includes 10 items, the first 5 items are evaluated obsessions, the rest are assessments compulsions. Each item 0-4 points, a total of 40 points. The lower the score, the better the outcome. | pre-treatment; 1 day post-treatment; Change from baseline score at 1 month | |
Secondary | Obsessive Compulsive Inventory-Revised (OCI-R) | a simplified version of the OCI for self-assessment of Obsessive symptoms, Revised to include only 18 items from 42 items in the original Obsessive Compulsive Questionnaire. Divided into six obsessional subscales, respectively washing (5, 11, 17), obsessional thinking (6, 12, 18), storage (1, 7, 13), sorting (3, 9, 15), check (2, 8, 14), mixed (4, 10, 16), can be very good to distinguish the characteristics of different obsessional symptoms. Each item was assessed on a five-point scale of 0 to 4, with 0 being "not at all" and 5 being "extremely painful," and participants were asked to tick a number that best described the extent of their pain or distress on a scale of 0 to 72, with higher scores indicating more severe obsessive-compulsive symptoms. The questionnaire is simple and easy to understand. It can objectively evaluate individual obsessive-compulsive symptoms from six dimensions, with high reliability (0.82) and validity (0.81). | pre-treatment; 1 day post-treatment | |
Secondary | Hamilton Depression Scale(HAMD) | Hamilton Depression Scale(HAMD): An assessment of depressive mood status with 17 questions on a Scale of 0 to 4. | pre-treatment; 1 day post-treatment | |
Secondary | Hamilton Anxiety Scale(HAMA) | Hamilton Anxiety Scale(HAMA):a scale of 14 questions on a scale of 0 to 4 on a 5 scale. | pre-treatment; 1 day post-treatment | |
Secondary | Stroop word test | To measure the conflict suppression ability of the subjects, consisting of three groups of cards, namely dot, word and color word. The subjects were asked to read the color as quickly and accurately as possible, and record the response time and accuracy. Behavioral indicators :(Stroop interference effects, SIE)= reaction time of color word - reaction time of word. | pre-treatment; 1 day post-treatment | |
Secondary | Behavioral index TMT=TMT-B reaction time - TMT-A reaction time. | Evaluate the executive function of the subjects, including attention, memory, thinking flexibility, reasoning, conversion and other broad executive function components, including A and B. TMT is simple and involves less cognitive involvement. TMT-B involves response inhibition and attentional switching. The task required the subjects to complete the connection according to certain rules and record the reaction time. Behavioral index TMT=TMT-B reaction time - TMT-A reaction time. | pre-treatment; 1 day post-treatment |
