PDDBI™

The PDDBI was developed to provide what many existing assessments of children with PDD lack: evaluation of change in functioning, assessment of response to intervention, assessment of adaptive and maladaptive behaviors, identification of meaningful subgroups, and much more.

The Primary Goals of the PDDBI

• Assess autism with age-standardized scores
• Includes items to measure problem behaviors and social communication skills
• Includes separate inventories for parents and teachers to address the issue of generalization 
• Includes a measurement system to be useful in measuring responsiveness to intervention and disentangling change due to treatment from change due to development
• Useful for multiple applications in various settings such as clinical, medical, academic, and research
