In which of these statements is the scientific rationale for distinguishing type 1 and type 2 most clearly illustrated?

Question

A. If subjects X and Y are identical twins and X is diagnosed with type 1 schizophrenia, it’s nearly 100 percent assured that Y will also develop type 1 schizophrenia
B. The symptomatic profile for type 1 and type 2 schizophrenia is different
C. Type 2 schizophrenics are most likely to be a threat to themselves and others
D. type 1 schizophrenics are most likely to be a threat to themselves and others

Answer 1

The scientific rationale for distinguishing type 1 and type 2 schizophrenia is most clearly illustrated by:

B. The symptomatic profile for type 1 and type 2 schizophrenia is different.

This statement highlights the differences in symptoms that justify the distinction between the two types, which is crucial for diagnosis and treatment. While the other statements provide information about genetic prediction, threats to safety, and behavior associated with each type, they do not explicitly address the differences in the symptomatic profiles, which is foundational to the classification.
