**4.1 Prevalence of disorders**

A preliminary synthesis of the research found that HR offspring had a greater prevalence of behavioural and emotional disorders in comparison to those without a parent with schizophrenia. It was also found there to be a greater prevalence of psychiatric disorders amongst HR offspring; for example, it was found there to be a 13.7% prevalence of psychiatric disorders amongst HR offspring [55]. Furthermore, HR offspring are at greater risk in developing at least one or more psychiatric conditions. It appeared that the greatest prevalence was for personality disorders amongst HR offspring. This signifies the negative impact parental schizophrenia has on the psychosocial well-being of HR offspring, regarding the development of a psychiatric disorder.
