Product Description
The ADI-R has proven effectiveness in differentiating autism from other developmental disorders, assessing syndrome boundaries, identifying new sub-groups and quantifying autistic symptomatology.
Composed of 93 items, the ADI-R focuses on three functional domains:
- Language and Communication
- Reciprocal Social Interactions
- Restricted, Repetitive and Stereotyped Behaviours and Interests
Interview questions cover eight content areas:
- The subject's background including family, education, previous diagnoses and medications
- Overview of the subject's behaviour
- Early development and development milestones
- Language acquisition and loss of language or other skills
- Current functioning in regard to language and communication
- Social development and play
- Interests and behaviours
- Clinically relevant behaviours such as aggression, self-injury and possible epileptic features.
ADI-R administration
To administer ADI-R, an experienced clinical interviewer questions a parent or caregiver who is familiar with the developmental history and current behaviour of the individual being evaluated.
Administration of the ADI-R requires use of the ADI-R Interview Protocol booklet which contains the 93 items. Following a standardised procedure, the interviewer records and codes the informant's responses in the Interview Protocol booklet.
ADI-R scoring and interpretation
The ADI-R Comprehensive Algorithm Form allows users to calculate and interpret any one of five age-specific ADI-R algorithms (two Diagnostic Algorithms that are based on developmental history and are used for formal diagnosis, and three Current Behavior Algorithms that focus on present functioning and are used for treatment and educational planning).
