M. Mueller et G. Pekarik, Treatment duration prediction: Client accuracy and its relationship to dropout, outcome, and satisfaction, PSYCHOTHER, 37(2), 2000, pp. 117-123
The relationship of clients' expected and actual treatment duration was inv
estigated for 230 clients in private practice settings. Clients both expect
ed and attended a relatively low number of visits. These patterns were disc
repant with therapists' duration expectations. A stepwise regression analys
is indicated that clients' expected number of visits was the single best pr
edictor of clients' actual number of visits and that history of eating diso
rder, therapist's degree, and client's years of education also contributed
to actual number of visits (R =.420). Clients who attended fewer sessions t
han expected had lower satisfaction, better outcome on two of six measures,
and were more often identified dropouts.
