Development of scales of severity of facial cleft impairment.
The reliability and validity of human judgments in rating the severity of cleft-related facial impairment were examined in this series of studies. The goal of the research was to develop scales for rating the severity of facial cleft impairment using psychophysical methods for measuring human judgment. The principle findings were: (1) Four photographic categorized scales with high inter-group reliability and satisfactory content and construct validity were developed; (2) Raters used objective stimulus characteristics of the face to scale impairment; (3) Ratings of facial attractiveness decreased as the severity of impairment increases; (4) Full face ratings of the severity of impairment correlated highly with ratings of the same photographs cropped below the eyes. The implications of these findings for clinical and research application are discussed.
