Which of the following represents one of the key changes from the DSM-4 to the DSM-5?

Choice A reason: This choice is incorrect because DSM-4 had already removed homosexuality as a psychiatric disorder in 1973, long before DSM-4 or DSM-5. Therefore, this does not represent a change between DSM-4 and DSM-5. Choice B reason: This choice is incorrect because DSM-5 actually emphasizes consideration of psychosocial and contextual factors in diagnosis, rather than eliminating them. The assessment still incorporates these factors in clinical formulation. Choice C reason: This choice is incorrect because DSM-5 eliminated the multiaxial system, which had five axes in DSM-4, and did not replace it with a two-axis system. The DSM-5 uses a single-axis approach with dimensional assessments. Choice D reason: This choice is correct because DSM-5 removed the multiaxial assessment system that was used in DSM-4, which included five separate axes for diagnosis. This is one of the primary structural changes between the two editions.
