Connors Abbreviated Parent-Teacher Rating Scale for ADHD

In its original form, the Connors Abbreviated Parent-Teacher Rating Scale for ADHD comprised 93  items rated on a 0 to 3 scale and was sub-grouped into 25 clusters, including problems with restlessness, temper, school, stealing, eating, and sleeping. Over the years, multiple versions of this scale were developed and used to aid in the systematic identification of children with ADHD. A highly abbreviated form of this rating scale, the Conners Abbreviated Parent-Teacher Questionnaire, was developed for use with both parents and teachers by Keith Connors in 1973. It comprises ten items that assess both hyperactivity and inattention.
