Mean ± SD; p values below .05 are statistically significant based on two-tailed t-tests. Note: Standard scores are based on a mean of 100 and a standard deviation of 15 (average range of 85-115) except for the CTOPP (based on mean of 10 and a standard deviation of 3; average range of 7-13) and NDRT (based on mean of 200 and a standard deviation of 25; average range of 175-225). SD = Standard deviation.
