Question

Quizplus · Accepted Answer

The decision to eliminate the subtypes of schizophrenia in DSM-5 was based on evidence that suggests that the previous subtypes were not qualitatively different disorders. This means that the subtypes did not have different underlying causes or treatment implications, and so they provide limited clinical utility. Therefore, option C is the correct choice. Option A is incorrect because the subtypes were not strong predictors of the course of the disorder. Option B is incorrect because there is no evidence that recent genetic findings led to the elimination of the subtypes. Option D is also incorrect because, while the subtypes were valid in the previous DSM versions, their removal from DSM-5 illustrates the evolution of the classification system based on new evidence and research findings.
