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

Choice A reason: Homosexuality was removed as a psychiatric disorder in the DSM-3 and is not a relevant change between DSM-4 and DSM-5. Choice B reason: The DSM-5 continues to consider psychosocial and environmental factors through the use of diagnostic codes and specifiers; it does not eliminate these considerations. Choice C reason: DSM-5 eliminated the multiaxial system of DSM-4; it does not use two axes, but instead provides a single-axis approach with descriptive specifiers and dimensional assessments. Choice D reason: The DSM-4 included a five-axis system (clinical disorders, personality disorders, medical conditions, psychosocial and environmental problems, and global assessment of functioning), which was a defining feature of its multiaxial assessment. This represents the key change when transitioning to DSM-5.
