The performance measures of only the subjects of the two groups that passed the effort test are compared in this table. The P values were determined with t-test for independent samples. CVLT, California Verbal Learning Test (2nd Edition); Rey, Rey-Osterrieth Complex Figure Test; WAIS4, Wechsler Adult Intelligence Scale (4th Edition); LD, long delay; SD, short delay; PTSD, posttraumatic stress disorder; TBI, traumatic brain injury.
T-Score (mean = 50; standard deviation = 10)
Z-score (mean = 0; standard deviation = 1)
Scaled Score (mean = 10; standard deviation = 3).
