Structure
The interview covers the referred individual’s full developmental history, is usually conducted in an office, home or other quiet setting by a psychiatrist or other trained and licensed professional, and generally takes one to two hours. The caregivers are asked 93 questions, spanning the three main behavioral areas, about either the individual’s current behavior or behavior at a certain point in time. The interview is divided into five sections: opening questions, communication questions, social development and play questions, repetitive and restricted behavior questions, and questions about general behavior problems. Because the ADI-R is an investigator-based interview, the questions are very open-ended and the investigator is able to obtain all of the information required to determine a valid rating for each behavior. For this reason, parents and caretakers usually feel very comfortable when taking part in this interview because what they have to say about their children is valued by the interviewer. Also, taking part in this interview helps parents obtain a better understanding of Autism Spectrum Disorder and the factors that lead to a diagnosis.

Famous quotes containing the word structure:
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
“Communism is a proposition to structure the world more reasonably, a proposition for changing the world. As such, we have to analyze it and, if we deem it reasonable, act upon it.”
—Friedrich Dürrenmatt (1921–1990)
“... the structure of a page of good prose is, analyzed logically, not something frozen but the vibrating of a bridge, which changes with every step one takes on it.”
—Robert Musil (1880–1942)
