Contracts for psychiatrists? (7)
This clue is a double definition.
'contracts' is the first definition.
('shrink' can be a synonym of 'contract')
'psychiatrists?' is the second definition.
('shrink' can be a synonym of 'psychiatrist')
'for' acts as a link.
(Other definitions for shrinks that I've seen before include "psychiatrists", "Contracts", "head examiners", "Reduces in size".)
