It compared relatives of suicide victims with relatives of demographically similar adolescents; both groups were examined for Axis I and II disorders, histories of aggression, and histories of suicidal behavior (Brent, Bridge, Johnson, & Connolly, 1996).

The increased risk for suicidal behavior in suicide probands, it was concluded from this study, is probably a trait independent of Axis I and II psychiatric disorders (Brent et al., 1996). Anorexia nervosa and bulimia often exist comorbid with other psychiatric disorders, such as depression, anxiety, and obsessive-compulsive disorder.

This coefficient ought to be higher in identical twins than in fraternal twins.

Origins of individual differences in infant shyness.

I am sure further research could answer these questions.

Reliability of the italian version of the 16-item Prodromal Questionnaire (iPQ-16) for psychosis risk screening in a young help-seeking community sample

I should have been more clear about that.

There is much unknown in this field, but the perusal and review of twin, adoption, and family studies is a significant stepping stone in better understanding this topic.
