psychotherapy

'treatment' is the definition.
(psychotherapy is a kind of treatment)

'hasty prophecy about' is the wordplay.
'about' indicates an anagram.
'hasty'+'prophecy'='hastyprophecy'
'hastyprophecy' anagrammed gives 'PSYCHOTHERAPY'.

'a form of behaviour' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
