In response to J. C. Norcross and J. S. Rossi's (see record 1994-38252-001) comment on our article (D. A. Shapiro et al; see record 1994-38260-001), we note that research as reported does not fully represent the processes whereby it was designed and completed. The true statistical power of an investigation reflects all the analyses carried out, not just those that get reported. The power of our analyses was sufficient to address the substantive questions at issue. The importance of these questions does not depend on allegiance to equivalent outcomes of diverse therapies. The outcome phase of the Second Sheffield Psychotherapy Project is but part of its broad strategic approach to advancing our understanding of the mechanisms of change in the psychotherapies.
