Planned programme in favour of Jung's initial shock treatment (7)
I believe the answer is:
project
'planned programme' is the definition.
'in favour of jung's initial shock treatment' is the wordplay.
'in favour of' becomes 'pro' (I've seen this before).
'initial' suggests taking the first letters.
'shock treatment' becomes 'ect' (ECT is an example).
The first letter of 'jungs' is 'j'.
'pro'+'j'+'ect'='PROJECT'
(Other definitions for project that I've seen before include "Scheme, hurl" , "Enterprise; stick out" , "Planned enterprise" , "low-cost housing" , "Lengthy task for student" .)
