Over the last 20 years, coalition building has become a prominent intervent
ion employed in communities across America. Coalitions provide community ps
ychologists and those in related fields with a chance to work with M,hole c
ommunities and to better understand how to create community change. As we r
eflect on the past two decades of community coalition building there are ma
ny questions to be answered about this phenomenon. Why has there been such
an upsurge in community coalition building activity? What is the impact of
this activity? What have we as students of community learned? What are the
questions that we need to be asking to improve the effectiveness of coaliti
on building efforts and their evaluation? This set of articles will review
the state of the art of community coalition building in both practice and r
esearch. The structure of the articles reflects a collaborative process, wi
th multiple contributors from different disciplines, using a variety of for
mats. Because this is an evolving phenomenon where the questions asked are
as important as the lessons learned, many of the major sections include dia
logues with community experts from across the country and from multiple fie
lds, including community psychology, public health, political science, publ
ic administration, and grassroots organizing.
