Psychotherapy research in managed health-care settings is discussed. I
nvestigations of the relationships between amount of therapy and subse
quent outcome adjusted by such patient characteristics as diagnosis, i
ndicators of illness chronicity and severity, and social support marke
rs are well suited to these settings. In addition, research on the eff
ectiveness of treatment guidelines, treatment manuals, alternative the
rapies, and alternatives to therapy is likely to be conducted in these
companies resulting in potentially important applied results. Finally
, investigations dealing with the selection and training of therapists
and care managers would seem to be particularly relevant in managed c
are. Problems associated with the conduct of research in these setting
s are presented including lack of experimental control, demand charact
eristics, and the effects of business decisions on the collection and
dissemination of data. On balance we conclude that managed healthcare
organizations will be an important future source of naturalistic studi
es on the effects of psychotherapy.
