Costs (booklets, forms, kit)

The BDI-2 NU Premium Complete Kit can cost up to $1,368 and includes test item books, examiner’s manual, stimulus book, presentation cards, complete record forms, workbooks, screening test item book with screening test record forms, screening presentation cards, screening stimulus book, complete set of BDI-2 manipulatives, and a blue canvas carrying case. All of these items can also be purchased individually.

Purpose

BDI-2 NU is an assessment tool that screens and evaluates early childhood developmental milestones through 5 domains and 13 subdomains. This assessment determines the child’s strengths and needs in personal-social, adaptive, motor, communication, and cognitive skill sets. The Normative Update was created to accommodate demographic changes of the U.S. population. No changes were made to the test structure, items, or item content. However, norms were recalculated using U.S. census projections for 2015. The complete test battery’s results can help identify specific domain delays and determine a child’s readiness for school and need for special education services.

Type of Test

The BDI-2 NU is a discriminative test that is norm-referenced to help identify delays in the 5 global development domains and need for additional services.

Target Population

Birth – 7 years and 11 months old

Time Requirements 

The battery can be completed in 60 to 90 minutes. The screener test can be administered in 10 to 30 minutes.

Test Administration

The BDI-2 NU includes modifications that allow it to be used with infants or children with special needs or disabilities, as well as different language versions. There are multiple administration options including structured, play based activities, observation, and scripted interviews for parents or caregivers. A single provider or a team consisting of multiple disciplines can administer the test.

Scoring and Type of Information Provided

Each of the 5 domains can be scored individually, but there is also a total score for all 5 domains. Each task is scored on a scale of 0-2.

Scoring for each task:

  • 0 – Future learning objective (child either did not attempt the task or gave the incorrect response)
  • 1 – Emerging Milestone (attempted task or possible immersion of the skill but not performed well enough for full marks)
  • 2 – Mastered Milestone (skill has been mastered and milestone reached)

Curriculum referenced: item-level scores indicating mastery of milestones

Criterion referenced: item-level data providing assessment of progress made; change sensitive scores (CSS) that measure subtle changes in a child’s growth (available in computer scoring options)

Norm referenced: determines developmental delays and eligibility for services

Article Summary:

The Relationship Between Preoperative Fetal Head Circumference and 2-year Cognitive Performance After Laser Surgery for Twin-Twin Transfusion Syndrome

Selective laser photocoagulation of communicating vessels (SLPCV) is a treatment for Twin-twin transfusion syndrome (TTTS) that is performed between 16 and 26 weeks of gestational age (GA). It has been previously noted that in children who had laser surgery for the treatment of TTTS, a smaller head circumference (HC) may be associated with lower overall cognitive performance. This study assessed HC following laser surgery for TTTS, and it’s association with cognitive performance assessed using the BDI-2. Each patent received an ultrasound examination for diagnosis of TTTS at initial assessment, also assessing preoperative HC. Laser surgery was performed within 24 hours of the ultrasound examination, between 16 and 26 weeks GA. The children were assessed at 24 months corrected age, which included a cognitive and developmental evaluation using the BDI-2 and HC measurement. The results indicated that larger preoperative HC was significantly associated with increased BDI-2 scores. The relationship between total BDI-2 scores and preoperative HC percentile increased linearly. In discussion, smaller preoperative HC percentiles identified children who were at risk of lower total BDI-2 scores at 2-years of corrected age, but still within normal range. However, there was no significant difference in HC percentiles between recipients and donors at 2-years corrected age, indicating that the donor twin is permitted to catch-up growth. Overall, the majority of children (donor and recipient twins) who receive laser surgery for TTTS remain within the normal range of BDI-2 score, so should not need any additional assistance postnatal.

    Hi Campbell! Can you tell me a little more about Twin-Twin Transfusion Syndrome? I am unfamiliar with this syndrome.

  2. cbrown72 says:

    Lindsey I am so glad you asked that question! TTTS is a rare disease that occurs in identical twins who share a placenta. It is due to abnormal blood vessel connections creating an unequal exchange of blood flow through the placental vasculature. This unequal blood flow results in blood volume depletion to one twin (donor) and overload of blood volume to the other twin (recipient). The difference in blood volume can effect development and growth, which is why preoperative head circumference (fetal brain growth) was used to correlate with neurodevelopment outcomes at 2 years corrected age. I am sure a quick google will give you a more detailed etiology of the syndrome.
