What is the prevalence of schizophrenia for a child with one parent diagnosed with the disorder?

• A. 10%
• B. 12%
• C. 20%
• D. 30%

Answer: (B)

The prevalence of schizophrenia in children with one diagnosed parent is approximately 10%. This statistic highlights the heritable nature of the disorder; individuals with a first-degree relative who has schizophrenia are at a significantly greater risk compared to the general population, where the lifetime prevalence is about 1%. The other options suggest higher rates of prevalence which do not align with the established statistics surrounding the risk of developing schizophrenia based on familial history. Research indicates that while having a parent with schizophrenia increases the risk, it does not approach the higher percentages suggested by the other choices. Understanding the genetic and environmental factors involved can help in estimating risk more accurately in children with a family history of this mental health condition.
