The Stability of Teacher Ratings on the Devereux Elementary School Behavior Rating Scale
AbstractThe stability of Devereux ratings (eleven factors, three items) was investigated for a sample comprised of 67 subjects from the primary unit of a suburban school organized with open classrooms and vertical grouping. The time interval between ratings was approximately one year. The reliabilities differed substantially for the fourteen scores. For the eleven factors, the median r was .73, but individual r’s ranged from .82 for Comprehension through.49 for Achievement Anxiety. The reliabilities for the three single items compared favorably with those for the eleven factors even though the latter were obtained by summing the scores for several items.
