The oral, obsessive, and hysterical personality syndromes. A study of hereditary and environmental factors by means of the twin method.
Lazare et al have demonstrated a factor structure similar to the oral, obsessive, and hysterical personality syndromes in a female patient population. The factor structure has been replicated in a sample of 99 predominantly "normal" females and male twin pairs. Furthermore, it was found that hysterical traits in female subjects and oral traits in male subjects seemed to have a genetic component. The study also indicated that environmental factors from an early age influence the development of the personality structure.
