The researchers had hypothesized that schizoida in a twin was how a schizophrenia carrier gene, one in a non-schizophrenic still passing on a genetic risk, expressed itself.

The power of twin designs arises from the fact that twins may be either identical (monozygotic (MZ), i.e. developing from a single fertilized egg and therefore sharing all of their polymorphic alleles) or fraternal (dizygotic (DZ), i.e. developing from two fertilized eggs and therefore sharing on average 50% of their alleles, the same level of genetic similarity found in non-twin siblings).

The following diagnostic systems and rating scales are used in psychiatry and clinical psychology.This list is by no means exhaustive or complete. For instance, in the category of depression, there are over two dozen depression rating scales that have been developed in the past eighty years.
The rate at which troops were hospitalized for mental illnesses has risen 87 percent since 2000, according to a July 2013 study by the Armed Forces Health Surveillance Center.
