Two-year test-retest reliability coefficients for IQ measures

Two-Year Prodromal HD (N = 371) Two-Year Controls (N = 51)
ANART number correct standard score 0.94 0.93
WASI Vocabulary standard score 0.86 0.82
WASI Matrix Reasoning standard score 0.68 0.72
two-subtest WASI Combined standard score 0.86 0.82

Note. IQ = intelligence quotient; HD = Huntington disease; ANART = American National Adult Reading Test; WASI = Wechsler Abbreviated Scale of Intelligence. All test-retest reliability coefficients (within group analysis) p < .0001.
