The BDI-3 yields a Developmental Quotient (DQ) for each developmental domain and an overall BDI-3 Total DQ Score that represents the child's development across all five developmental domains. A DQ score is a standard score that has a mean of 100 and a standard deviation of 15.
However, like the BDI-IA, the BDI-II is scored by summing the highest ratings for each of the 21 items. Each item is rated on a four-point scale ranging from 0 to 3, and the total scores can range from 0 to 63 – the higher the total score, the greater the severity of symptoms.
The results of the BDI-2 are given in terms of developmental quotients. Average scores range between 85 and 115. In order to be eligible for Early Intervention, a child must have a score of 77 or below, which is a 1.5 standard deviation below the average.
The Battelle Developmental Inventory, Third Edition (BDI-3), appropriate for use with children from birth to 7 years, 11 months, measures mastery of those developmental milestones in the following global domains: Communication. Social Emotional. Adaptive.
It is norm-based, meaning that scores are generated by the child's performance based on the performance of same-aged peers on the same items.
The Battelle Developmental Inventory is a clinical-administered assessment that measures mastery of developmental milestones in the global domains of communication, social-emotional, adaptive, motor, and cognitive development. It is appropriate for use with children from birth to 7 years, 11 months.
