Study Details
Study Description
Brief Summary
There is some cognitive impairment in patients with bipolar depression. THINC-it is a simple, fast and free cognitive assessment tool. It has good reliability and validity in patients with depression, but its application in patients with bipolar depression is not clear. The purpose of this study is to verify the reliability and validity of THINC-it cognitive test in bipolar depression, and to further explore the difference of cognitive impairment between attack and remission of bipolar depression, so as to provide empirical research basis for clinical evaluation-based treatment.

Detailed Description
There is some cognitive impairment in patients with bipolar depression. THINC-it is a simple, fast and free cognitive assessment tool. It has good reliability and validity in patients with depression, but its application in patients with bipolar depression is not clear.
This study includes three steps.
-
baseline: demographic data, sequential test THINC-it and standard test tools, clinical scale evaluation, to verify the discriminant validity and parallel validity of THINC-it in bipolar depression.
-
follow-up (1 week): 30-50 patients with stable bipolar depression were evaluated by clinical scale and THINC-it test to verify the test-retest reliability of THINC-it in bipolar depression.
-
follow-up (8 weeks): all patients with bipolar depression were evaluated by clinical scale, THINC-it test, longitudinal comparison data, and the influencing factors of cognitive impairment were analyzed.

Outcome Measures
Primary Outcome Measures
- Composite THINC-it Tool Score [up to 8 week]
The composite THINC-it tool score is the integrated total score of results from performance on five sub-component cognitive tests of the THINC-it tool.
- CANTAB reaction time (RTI) [Up to 1 week]
online computer test, RTI evaluates the response speed of movement and psychology, as well as activity time, reaction time, accurate value and error value of response, and calculates the time required to correctly evaluate the occurrence of stimuli in one location.
- 1-back memory task (1-back) [Up to 1 week]
the subjects' attention, memory, reaction speed and executive function were tested.
- Digit Symbol Substitution Test (DSST) [Up to 1 week]
participants in the digital symbol substitution test calculated the correct total number by matching symbols and numbers as soon as possible within 90 seconds according to the coding table.
- Trail Making Test B [Up to 1 week]
he subjects calculated the completion time according to the cross-connection of numbers and letters. The higher the score, the more obvious the functional damage.
Secondary Outcome Measures
- Sheehan Disability scale (SDS) [Up to 8 week]
Evaluation of the severity of overall functional impairment
- HAM-D [Up to 8 week]
Assess the state of depression
- HAM-A [Up to 8 week]
Assessing anxiety state
