Examining Rater Behavior on a Revised Version of the Short Child Occupational Profile (SCOPE)

Abstract

A previous study of the Short Child Occupational Profile (SCOPE), an assessment of occupational participation, supported the psychometric soundness of the instrument overall, but pointed to some potential problems in practitioners' use of the SCOPE in practice. Specific revisions were made to the SCOPE to address the rating behaviors of leniency/severity, halo effect, and restriction of range. A many-faceted Rasch model analysis was conducted after 39 practitioners working in eight practice sites learned to administer the SCOPE using a variety of methods and rated 168 clients using the SCOPE (version 2.1). Practitioners exhibited three significantly different levels of leniency/severity, 35 practitioners did not exhibit any halo effects, and the top three rating categories were used 91% of the time. Findings suggest that a variety of methods can be used to learn to administer and rate the SCOPE in an appropriate manner to assess the personal and environmental factors affecting the occupational participation of children.
