The Behavior Observation Scale for Autism (BOS): Factor Analysis of Behaviors.
Freeman, B. J.; And Others
Data on 36 autistic, 30 mentally retarded (MR), and 22 normal children (23-65 months old) was collected to develop a method of objective behavioral assessment for diagnosing autism and documenting symptom changes over time. Ss were observed and rated on the Behavior Observation Scale, an instrument which contains 67 objectively defined behaviors in the areas of general behaviors, language, response to stimuli, attending response, response to being held, inappropriate response to pain, and motility disturbance to stimuli. Factor analyses were performed for each diagnostic group. When the individual groups were examined, the autistic group could best be characterized by behaviors reflecting inappropriate interaction with people and objects; the MR group could best be characterized by solitary behaviors; and the normal group behavior could best be characterized by appropriate interactions with people and objects. (Operational definitions and procedures are detailed, and factor analyses of the preliminary data on 89 children are reported.) (SBH)
