Overview

The BDI-2 is an individualized assessment that may be used for a variety of purposes, including diagnosis, eligibility, determination of discrepancies, reevaluation, and instructional planning.  Appropriate for ages birth through 7.11 years, the BDI-2 is ideal for several uses:

The BDI-2 offers two types of assessment: the full assessment and the screening test.  The full assessment refers to the use of the complete instrument, including all five domains.  The screening test refers to an abbreviated instrument that includes 100 test items from the full BDI-2.  The results of the screening test indicate whether it is advisable to administer the full BDI-2. 

Below is a chart that maps the structure of the BDI-2 domains and subdomains:

Adaptive Domain Personal-Social Domain Communication Domain Motor Domain Cognitive Domain

Administration

Complete BDI-2: 1-2 hours; Screening Test: 10-30 minutes.

Administration of the BDI-2 can begin in any of the five domains.  The start points for each subdomain are clearly marked and are determined by the age or estimated ability level of the child.  Examiners proceed though each of the subdomains to determine the child's level of development.

Technical Qualities

Standardization

Normative data for the BDI-2 were gathered from over 2500 children between the ages of Birth through 7 years, 11 months. The normative sample closely matches the 2000 U.S. Census (education level based on 2001 data). Bias reviews were conducted on all items for gender and ethnicity concerns. Item desirability information from examiners was also considered in the selection of the final items.

Reliability and Validity

Reliabilities for the BDI-2 meet or exceed traditional standards for excellence at the subdomain, domain, and full test composite levels. Concurrent and criterion validity were obtained using the original Battelle Developmental Inventory; the Bayley Scales of Infant Development, Second Edition ; Woodcock-Johnson® III; Denver Developmental Screening Test, Second Edition; Preschool Language Scale, Fourth Edition; Vineland Social-Emotional Early Childhood Scales; and Wechsler Preschool and Primary Scale of Intelligence, Third Edition. All validity and reliability information is contained in the Examiner's Manual.
