Notes. PANSS = Positive and Negative Syndrome Scale; Non-EF Cognitive Composite = Non-Executive Function Cognitive Composite; TMT_B=Trail Making Test Part B; WCST_Cat=Wisconsin Card Sorting Test, Categories Completed; UPSA = University of California San Diego Performance-Based Skills Assessment; SLOF = Specific Levels of Functioning scale.
PANSS total score with higher scores reflecting more severe psychopathology.
Factor score reflecting a composite of the following neuropsychological tests: Letter-Number Sequencing, Digit Span, Verbal Fluency, Rey Auditory Verbal Learning Test, Animal Naming, Boston Naming Test, Trail Making Test Part A, and Digit Symbol.
Scores can range from 0 to 240 seconds, with higher scores reflecting more impaired performance.
Scores can range from 0 to 6, with lower scores reflecting more impaired performance.
Scores can range from 0 to 100, with higher scores reflecting higher functional capacity.
Scores can range from 24 to 120 with lower scores indicating more assistance is needed to perform functional skills. SLOF work scores can range from 6 to 30, SLOF Activities scores can range from 11 to 55, SLOF Interpersonal scores can range from 7 to 35. For each domain, lower scores indicate more assistance needed to perform that skill.
