When you face your fears, have senior party thrown out (8,7)

I believe the answer is:

aversion therapy

I'm a little stuck... Click here to teach me more about this clue!

'when you face your fears' is the definition.
I can't tell whether this defines the answer.

'have senior party thrown out' is the wordplay.
'thrown out' is an anagram indicator.
'have'+'senior'+'party'='haveseniorparty'
'haveseniorparty' is an anagram of 'AVERSION THERAPY'.

Can you help me to learn more?

(Other definitions for aversion therapy that I've seen before include "Behaviour modification technique" , "Type of treatment" , "Medical treatment" , "addict's treatment" .)

I've seen this clue in The Irish Times.
