Autism Developmental Instrument (ADI)

Increase your autism intervention success with ADI

What is the ADI?


The Autism Developmental Instrument (ADI) assesses the needs of a person with autism.  It is easy to administer and gives immediate results that can be automatically mapped to program templates so that treatment plans are streamlined.  The assessment can be retaken numerous times to track the needs of an individual over time.

The ADI is based on the Model of Hierarchical Complexity (MHC), an innovative framework for scoring based on the complexity of a behavior.  The MHC analyzes skill level based on the developmental difficulty of tasks.  The ADI provides an easy to use method of actively applying the model to behavior therapy.



Who is the ADI for?


Autism treatment providers, schools and clinics worldwide can benefit from the Autism Developmental Instrument (ADI).  


Why should you use the ADI?

Unlike other assessments in the field, the ADI is a behavioral-developmental based assessment. It is designed to increase the effectiveness of autism interventions by assessing the needs of a person with autism as early as their initial months of development.  The assessment is designed to be bias-free, effective across cultures and used repeatedly to assess behavioral changes over time.

By combining assessment questions, scoring, and the ability to suggest related programs and to track progress over years, the ADI, delivered via the UnitusTI electronic data management cloud, is a complete toolset that is designed to maximize the success of autism treatment programs in schools and clinics. 

ADI is more comprehensive than other assessments in testing the social and communicative domains involved in development. ADI comes with a built in scoring system, providing immediate results. ADI has been tested and has an ‘r’ value of 0.9 of predicting task difficulty, which is higher than most of the other assessments. The assessment is easy to administer, requiring no special training.  Results are immediate.

Top reasons why the ADI is superior:

  1. The ADI is easy to administer.

  2. The ADI can identify the specific domains in which the children require most immediate intervention.

  3. The ADI increases effectiveness of intervention. It helps assign participants to where they will benefit the most.

  4. The ADI allows for the monitoring of the effectiveness of the intervention. It can track the child’s progress over years.

  5. The earlier an intervention, the more successful it will be; with the ADI, tasks can be measured for children in their initial months of development.

  6. Unlike the other assessment tools in the market, the ADI is a behaviorally-developmentally based assessment.

  7. The ADI task performance is measured using the Order of Hierarchical Complexity (OHC), which is a representation of the mathematically behavioral aprioi task difficulty. As task difficulty increases, the OHC also increases.

  8. The ADI is designed to be bias-free, effective across cultures and used repeatedly to assess behavioral changes over time.

  9. The ADI is more comprehensive that other assessments in testing the social and communicative domains involved in the child’s development.

  10. The ADI comes with a built in scoring system, allowing for immediate results.

  11. With increased streamlining and success of interventions, the ADI may reduce the turnover rate of professionals working with children on the spectrum.

  12. The ADI is filled out by an observer either the parent or caregiver and can be administered multiple times with the same child.

  13. The ADI has been tested and has an ‘r’ value of 0.9 of predicting task difficulty, which is higher than most of the other assessments.


How does it work?


Delivered through our innovative UnitusTI cloud service.  Access from any device, anywhere in the world.


The Autism Developmental Instrument (ADI) is delivered as an add-on to your subscription to the UnitusTI cloud.  The assessment is administered through a series of questions that are scored by an observer based on behavior during the administration of the instrument.  Results are immediate and scores can be linked to related programs so that the results are automatically redirected to program assignment, creating a seamless path from assessment to intervention.  

With UnitusTI's program template creation feature, you can use your own programs or purchase a subscription to one of our ready-made curricula.  Run the programs in UnitusTI and track your client acquisition data, maintenance data and create customizable reports for insurance, staff or clients.

Creator of the Autism Developmental Instrument (ADI)

Michael Lamport Commons, Core Complexity Solutions© 

Dr. Michael Lamport Commons is a theoretical behavioral and complex systems scientist. He developed the model of hierarchical complexity upon which some of the instruments are based. In addition to being on the Corresponding member of the faculty of the department of Psychiatry at Harvard Medical School , he co-founded the Society for Quantitative Analysis of Behavior, the Society for Research in Adult Development, the European Society for Research in Adult Development, the Society for Terrorism Research, and the Developmental Behavior Analysis Special Interest Group in the Association for Behavior Analysis International. The largest part of his research has centered around the Model of Hierarchical Complexity of tasks and the corresponding stage of performance on those tasks. This includes studies of stage transition as in the study of the acquisition of formal stage behavior by 5th and 6th graders. The Model of Hierarchical Complexity has been applied in the moral and social (including attachment, empathy) domains, mathematics, logic, physics and chemistry domains.

With Patrice Marie Miller and others, he has published on the importance of attachment parenting and co-sleeping, attachment, and its relationship to the development of emotional regulation, the lack of which results in attachment disorders and therefore personality disorders.
