The recent move toward the recognition of empirically supported treatments
(ESTs) within numerous facets of the field of clinical psychology has been
met with general enthusiasm. The EST movement would not have been possible
without the efforts of earlier treatment researchers. Paradoxically, this i
s also a time when some of the leaders in clinical psychology are recognizi
ng that there is a paucity of experimental treatment research being conduct
ed today relative to the high volume of correlationally based, explicative
research, which examines the associations among variables. In this paper we
present numerous reasons for the relative excess of explicative research a
nd the paucity of treatment outcome research. Clinical practice is used to
exemplify how assessment-oriented, explicative activities and the design of
treatment can be integrated. A research-based example in which explicative
research is used directly to inform the design of the intervention in trea
tment outcome research is presented as one model for emulation. Specific re
commendations are made to help guide professionals and students entering th
e field who wish to conduct treatment research. An expansion on some of the
themes highlighted in this paper can be found in the chapter from which it
was in part derived (Blount, Bunke, & Zaff, 1999).
