The Development of the Obsessive-Compulsive Disorder School Impact Scale: An Investigation Using the Accuracy-Reliability Paradigm for Scale Validation.
Kratochwill, Thomas R.; Johnston, Hugh; Racine, Caroline N.
This report describes the development of a rating scale and direct observation measure to monitor the treatment of Obsessive Compulsive Disorder (OCD) in the home or school setting. The study applied an accuracy-reliability paradigm to validate the newly created rating scale and observation measure. An incontrovertible index using a scripted performance captured on videotape was developed. Participants included 10 student actors, an adult actor (the teacher), six trained graduate student observers, and nine experts in the field of OCD. Major findings included: (1) OCD expert ratings and observations ranged from moderately accurate to accurate; (2) graduate student observers were fairly reliable using the direct observation system and rating scale; (3) moderate to moderately high correlations were found between observations and ratings; (4) the direct observation system demonstrated sensitivity to change in the expected direction for the four target behaviors; and (5) the rating scale demonstrated sensitivity to change when the experts completed it, but not when the graduate students used it. Individual chapters of the report provide an introduction, a literature review, methodology explanation, presentation of results, and a discussion. Appendices include letters, coding information, the training manual, and the raw data. (Contains 59 references.) (DB)
