The use of interdisciplinary teams to address human service delivery i
ssues is becoming increasingly common. Complicated problem require the
expertise of a variety of specialists from different disciplines, and
increased specialization brings with it a heightened need for interdi
sciplinary collaboration. While team meetings are expected to serve as
the vehicle for successful collaboration among professionals three ba
rriers often stand in the way of effective team interactions: disorgan
ization, misunderstandings, and problem-solving difficulties. These pr
oblems suggest a need for interventions aimed at improving team commun
ication and decision-making processes, as well as a need for methods t
o observe and evaluate the effects of such interventions on a team's f
unctioning The purpose of this research was twofold: First, we sought
to investigate the effects of an intervention that differentially targ
eted and trained three sets of group communication and decision-making
skills aimed at addressing the three barriers mentioned above A secon
d goal was to develop new methods of observation that would overcome s
everal serious limitations which have characterized the bulk of existi
ng team intervention research An interdisciplinary rehabilitation clin
ic's staff served as the subject of the study. Using a multiple baseli
ne design across categories of behaviors, the effects of a three-part
intervention on the team's day-to-day meeting behavior was assessed. W
hile there was substantial variability and overlap in much of the data
, videotaped observations revealed that following each training sessio
n, there were modest increases in the average frequency of use of most
targeted behaviors. Social validation data indicated that team member
s found the training to be both useful and enjoyable. Implication for
future research are discussed
