[Prevalence and familiarity of personality disorders in Germany: results of the Greifswald family study].

There are only few data about the prevalence and familiarity of personality disorders (PD) in population based samples in Germany. Moreover, nearly no information exists for the prevalence of PDs among young adults. Thus, in the current study we examined the prevalence, familiarity and psychopathology of PDs, whereby middle-aged adults (about 45 years old) as well as the adult children of these persons (about 20 years old) were examined.
