Battelle Developmental Inventory, 2nd Edition Normative Update (BDI-2 NU)

Battelle Developmental Inventory, Second Edition Normative Update (BDI-2 NU) is an early childhood instrument based on the concepts of developmental milestones. As a child develops, he or she typically attains critical skills and behaviors sequentially from simple to complex. BDI-2 NU helps measure a child's progress along this developmental continuum by both global domains and discrete skill sets. BDI-2 NU is aligned to the three OSEP Early Childhood Outcomes, as well as the Head Start Child Outcomes. It can be used to meet the federal reporting requirements across Part C, Part B/619, and Head Start programs. The BDI-2 NU includes re-weighted normative data based on 2015 U.S. Census data projections to meet federal requirements for eligibility.

The overall composite score is reported.

There are five domain scores and 13 subdomain scores:

• Adaptive domain
• Self-care
• Personal responsibility
• Personal-social domain
• Adult interaction
• Peer interaction
• Self-concept and social role
• Communication domain
• Receptive communication
• Expressive communication
• Motor domain
• Gross motor
• Fine motor
• Perceptual motor
• Cognitive domain
• Attention and memory
• Reasoning and academic skills
• Perception and concepts

A scoring manual and software are provided by the assessment developers.

Percentile ranks and confidence intervals are provided for the subdomain scores and developmental quotients. Age-equivalent tables are also available. Reporting is also available through the BDI-2 Data Manager.

Data was collected from 2,500 children ages birth to 7 years, 11 months from four U.S. census regions: Northeast, Midwest, South, and West.

Internal consistency reliability estimates (coefficient alpha) for subdomains ranged from 0.85 to 0.95. Total score reliability (coefficient alpha) was 0.99.

Evidence based on content

No information available in the references.

Evidence based on response processes

New items were piloted in a separate study, and items were revised deleted or replaced based on this pilot. Ease of administration and child responsiveness were examined, and these factors were used to select items for the final version.

Evidence based on internal structure

No information available in the references reviewed.

Evidence based on relations with other variables

BDI-2 subdomain scores correlated positively with scores on the Bayley Scales of Infant Development, Second Edition on similar constructs (between 0.48 and 0.75). Studies suggest that BDI-2 scores can accurately identify students from special populations (autism, cognitive delays, prematurity, and speech/language delays). Accuracy rates ranged from 0.75 to 0.91.
