Comparing relationship researchers to children engaging in parallel pl
ay, the author questions the popular impression that the field of pers
onal relationships is interdisciplinary. The term 'interdisciplinary'
is contrasted with 'multidisciplinary'. Being interdisciplinary requir
es researchers to integrate different perspectives on the same problem
from more than one discipline. Being multidisciplinary requires only
that researchers representing different disciplines be brought togethe
r and work on separate problems relevant to their own disciplines. Sca
nning a sample of the relationship literature, the author concludes th
at the field is more multidisciplinary than interdisciplinary. It is a
field that approaches similar problems from different perspectives, b
ut rarely integrates disparate work into a cohesive whole. With concre
te suggestions, the author encourages relationship researchers from di
fferent disciplines to foster closer working relationships with one an
other in order to integrate their perspectives.
