Symbol Coding (SC)
Zeitfenster: screen, baseline, weeks2, 4, and 8
|
The Symbol Coding (SC) is a coding paradigm adapted from the Digit Symbol Substitution Test (DSST), both of which use essentially the same method, except in reverse; instead of drawing symbols that match digits, the SC requires to write the matching digit in the blank.
The task has been included as a subtest in the Brief Assessment of Cognition in Schizophrenia; in this task, subjects are required to write numerals 1-9 as matches to nonmeaningful symbols on a response sheet for 90 s, as based on a key provided to them, with higher scores reflecting better performance.

Hopkins Verbal Learning Test-Revised (HVLT-R)
Zeitfenster: baseline, weeks 2, 4, and 8
|
Hopkins Verbal Learning Test-Revised (HVLT-R) is a widely used neuropsychological assessment tool designed to evaluate verbal memory and cognitive function.
Developed by J. Brandt and Benedict in 2001, the HVLT-R consists of a list of 12 nouns divided into three semantic categories (e.g., dwelling places, four-legged animals, and precious stones), with four words per category.
The assessment involves three learning trials, where participants are presented with the list of words and are asked to recall as many words as possible immediately after each presentation.
Additionally, there is a delayed recall trial, where participants are asked to recall the words after a delay of 20-25 minutes.
The scoring principle is based on the number of correctly recalled words during each learning trial and the delayed recall trial.
The total score for the three learning trials and the delayed recall trial is calculated as well.
