Alpha ratings for internal consistency ranged from 0.43 to 0.85 for the 20 folk scales, but the median score was 0.76. For the 3 Vector Scales, the alpha ratings were 0.77 to 0.78 and for the 13 specialty scales, it was 0.45 to 0.88 (median above 0.70). Empirical evidence showed that reasonable to high correlations, 0.4 to 0.8, for the Folk and Vector scale with other personality instruments.
