Table 3.
Total genetic and environmental variance of Antisocial Personality Disorder criteria and the percentages attributable to the common factor
| Genetic variance | Environmental variance | |||
|---|---|---|---|---|
| Criterion | a2 | Common factor% | e2 | Common factor% |
| 1. Not conforming | 0.41 | 74 | 0.59 | 48 |
| 2. Deceitfulness | 0.36 | 54 | 0.64 | 28 |
| 3. Impulsivity, or failure to plan | 0.44 | 57 | 0.56 | 41 |
| 4. Irritability/repeated fights | 0.67 | 53 | 0.33 | 100 |
| 5. Reckless disregard | 0.28 | 61 | 0.72 | 22 |
| 6. Irresponsibility | 0.49 | 56 | 0.51 | 49 |
| 7. Lack of remorse | 0.42 | 100 | 0.58 | 66 |
Note: the values correspond the best-fit model illustrated in the Figure 3. a2 = heritability or proportion of variance in liability to endorse a criterion because of genetic factors; e2 = proportion of variance in liability attributable to environmental factors. “Common factor%” refers to the percentage of the variance component that is attributable to the biometric common-pathway factor, the rest being attributable to the influences specific to the given criterion.
