Equivalence testing for use in psychosocial and services research: An introduction with examples
BL Stegner, AG Bostrom, TK Greenfield - Evaluation and Program Planning, 1996 - Elsevier
This paper provides an introductory presentation of current equivalence methodology that is
a preferred alternative to usual power analyses when one wishes to assert that
performances on given outcome measures for different samples are equivalent, that is, could
have come from the same population. Such an approach may be important for mental health
policy makers who are comparing effectiveness of two systems of care that appear to have
similar outcomes but nontrivial differences in cost or other organizational characteristics.
