student's question

[Michael Sylvester]

A student asked about the process involved in adopting new labels or
changing labels in psychology.
For examples,did they take a vote to use DID instead of MPD?
Who has the final authority on that?
There maybe other changed terminologies.But his question was who decides
to do away with a terminology and adopt a different terminology.
The APA?
