Home self-assessment of obsessive-compulsive disorder. Use of a manual and a computer-conducted telephone interview: two UK-US studies.

Abstract

Two studies tested whether subjects with obsessive-compulsive disorder could successfully use BT STEPS, a computer-aided system, to perform self-assessment for self-treatment of obsessive-compulsive disorder by exposure and ritual prevention. Subjects were given a self-guiding manual and could use a touch-tone telephone to access computer-controlled Interactive Voice Response interviews at their convenience from home. Using the BT STEPS system, patients rated themselves and worked out a plan for individually tailored self-exposure therapy. Outcomes were similar in the two studies. Of the 63 subjects who used BT STEPS, 84% completed the self-assessment module. Most calls were made outside usual office hours. As expected, subjects did not improve merely by completing self-assessment. However, completion of self-assessment predicted later improvement with self-exposure therapy. Most subjects successfully completed self-assessment using BT STEPS from their homes. BT STEPS is a trademark of Pfizer, Inc. I.M.M., L.B. and J.H.G. have a financial interest in BT STEPS.
