Managed Health Care programs are beginning to look to findings from ps
ychotherapy outcome research to help set policy. This fact introduces
the need to consider outcomes research from the standpoint of usabilit
y or utility. It also provides a unique opportunity to integrate scien
ce and practice. From a different perspective, considering and applyin
g outcomes in this context requires selfless cooperation between scien
tists and practitioners, the willingness of each group to set aside gu
ild agenda, and giving up favored but insupportable beliefs and practi
ces on the parts of those in both scientist and practitioner camps. Th
is type of cooperation, while very challenging, may have mutual pay-of
fs. This article considers some of the obstacles both to this type of
sacrifice and evaluates some of the potential costs of cooperating. It
also provides some perspectives on the promising new roles of psychol
ogical assessment and methods of outcome research which would provide
a scientific basis for the function of managed health care.
