Answer:
Identify various psychological disorders, option D
Step-by-step explanation:
The Diagnostic and Statistical Manual of Mental Disorders, Fifth edition, also known as the DSM-5, is (as it sounds) a diagnostic tool used by mental health providers to identify the numerous psychological disorders currently well known and well researched. Each of the disorders within this text has a set of known signs and symptoms that patients with the condition exhibit. Psychologists can note which symptoms their current patient is presenting with and then peruse their DSM-5 to see which condition(s) they best align with, which can then dictate the basis for the patient's individualized treatment plan.
In short, the DSM-5 is used to identify psychological disorders, option D.
