ADI-R administration process. The parent is interviewed by a clinician. The clinicians asks open-ended questions that are tied to an item and listens to the responses from a parent. Typically the clinician is listening and asking about specific examples of the child’s behavior in relation to the item at hand. The clinician records a rating based on the presented information and can leave notes to themselves. After the interview is complete the clinician uses their recorded ratings to complete the ADI-R algorithm computing whether the child meets the instrument’s cut-off thresholds for ASD.
