LOOKING AS STRONGLY AS WE SHOULD IN THE RIGHT PLACES - REPLY TO NORCROSS AND ROSSI (1994)

In response to Norcross and Rossi's (1994) comment on our article (Sha piro, Barkham, Rees, Hardy, Reynolds, & Startup, 1994), we note that r esearch as reported does not fully represent the processes whereby it was designed and completed. The true statistical power of an investiga tion reflects all the analyses carried out, not just those that get re ported. The power of our analyses was sufficient to address the substa ntive questions at issue. The importance of these questions does not d epend on allegiance to equivalent outcomes of diverse therapies. The o utcome 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.
