Answer :
Final answer:
The main difference between DSM-IV and DSM-V is (B) There is no GAF score assessed or documented in the DSM-V.
Explanation:
The principal difference between the DSM-IV and the DSM-V is centered around the structural changes in the diagnostic criteria of mental disorders. Notably, the DSM-V no longer uses the multiaxial system that was a key feature in the DSM-IV.
Specifically, answer B is correct as there is no Global Assessment of Functioning (GAF) score assessed or documented in the DSM-V. The GAF score was previously used as Axis V in the DSM-IV to provide a global assessment of the individual's functioning. In the DSM-V, the previous axes I, II, and III are combined, thus integrating major psychiatric, personality, and medical disorders.
These changes highlight a shift towards a non-axial documentation which allows for a more nuanced understanding of an individual's condition.
Furthermore, the DSM-V includes revisions in organization and naming of categories and in the diagnostic criteria for various disorders, placing emphasis on the need to account for gender and cultural differences in the expression of symptoms. It also introduces the Cultural Formulation Interview, to better assess the cultural context of a patient's condition, which wasn't as developed in the DSM-IV.
