A recent project at the Hastings Center examined the question of prior
ity setting in the provision of mental health services. A central issu
e was whether those services should bc prioritized independently of ot
her health services. The answer to that question was no: they should h
ave full parity. Even so, priority setting can be a complex venture. A
t the heart of any such effort will be the relationship between empiri
cal evidence on treatment outcomes and efficacy and the political and
ethical interests that legitimately bear on interpreting and using tha
t evidence. An argument is made that a priority should be given those
whose suffering and inability to function in ordinary life is most pro
nounced. even if the available treatment for them is comparatively les
s efficacious than for other conditions.
