Since behavioral consultation was first described 20 years ago, a numb
er of assumptions have emerged in the literature and gained legendary
status despite being based either on weak or non-existent data. Noell
and Witt (1996) initially identified five assumptions underlying behav
ioral consultation including: (a) consultative services are more cost
efficient than direct intervention, (b) collaborative consultation are
more effective than expert consultation, (c) verbal interactions with
teachers result in significant behavior change, (d) skills learned du
ring the consultation interaction will generalize across subjects and
behaviors, and (e) direct contact with the client are unnecessary for
behavior change to occur. Because these assumptions do not have a soli
d empirical basis, we prefer to call them ''myths.'' In an attempt to
''demythtify'' behavioral consultation, we present four additional myt
hs not previously discussed to further emphasize that what many practi
tioners have been taught about how to conduct consultation may not be
the most effective means for teaching consultees new skills, improving
treatment integrity, and improving client outcome. We also hope to pr
ovide an impetus for new research directions to enhance the effectiven
ess of consultation practice.
