An alternative way to characterize the degree to which individual disorders or traits reflect the genetic common factor is to calculate the percentage of their heritability shared with the common factor. These results are shown in Table 2. Using this measure, ASPD is the disorder most strongly related to the externalizing factor in males followed by AAD, CD and DAD. MD, ND and ADHD are distinctly lower on this index, and CaD is near zero. Of the personality traits, the highest value is obtained by NS, followed by N and SS. E scores a zero.
