Growing numbers of clinicians and researchers from the major therapeut
ic orientations have begun to demonstrate an open attitude toward pote
ntial contributions of other approaches. Efforts at rapprochment and i
ntegration sharply contrast with the acrimonious debates that prevaile
d in the field a few decades ago. These efforts represent much needed
attempts to better understand psychotherapy and to improve its effecti
veness. In this article, the factors that have contributed to the emer
gence and development of psychotherapy integration are described, incl
uding the inadequacies of predominant models, limited effectiveness of
existing treatments, and external pressures for the accountability of
psychotherapy. Also reviewed are core issues within the integration m
ovement itself, such as the search for theoretical integration, elabor
ation of eclectic therapies, identification of conceptual convergence
and common factors, development of integrative approaches for particul
ar clinical problems, and improvement in major orientations as a resul
t of transtheoretical dialogue. Finally, several unresolved issues and
unanswered questions facing psychotherapy integration are described,
as they suggest future directions for the development of this movement
