Purpose

The purpose of NIHTB-CB was to design a brief assessment tool for variety of researchers that would measure neurological functions across the lifespan, but with a particular emphasis on longitudinal epidemiologic studies and intervention trails.

Cost Description

The annual subscription costs for the NIHTB (V3) is $599.99 plus the cost of equipment (iPad, Bluetooth keyboard, batteries).

The yearly subscription price is for up to 2 iPads. Additional subscription options are up to 6 devices for $1,499.99 and up to 10 for $2,499.99. It also includes the NIH Toolbox batteries for emotion, motor and sensory domains. Plus, access to PROMIS, Neuro-QOl, TBI-QOL, SCI-QLI and SCI-fI, and ECOG. The subscription is auto-renewing. There is a free 14 day trial period, but one is not able to save data or export reports.

The cost of the public V2 apps will increase to $749.99 with anticipated annual increases of $250 on June 1 from 2025 through 2027.

Key Descriptions

  • Brief measures that were designed to provide a common currency between researchers in the cognitive domains to assess domains that are important for school and work.
  • The NIH Toolbox Version 3 (V3) update was released in 2023 with an enhanced user interface, advanced data management capabilities, and expanded features including addition of new and improved tests with updated normed scores. The NIH Toolbox V2 will be retired, with annual subscriptions for both the English and Spanish versions no longer sold after June 30, 2027 and the last subscription expiring on June 30, 2028. Official support for the V2 app will cease after August 2028.
  • Seven main sub tests that cover attention, executive functioning, language, memory, and processing speed.
  • A new normative sample was collected for the NIH Toolbox Cognition Tests and Standing Balance Test (Motor Domain) as part of the 2023 Version 3 update with sample demographics representative of the 2020 U.S. Census.
  • For those ages 4-6 there is an Early Childhood Composite score derived from the scores for the Dimensional Change Card Sort, Flanker, Picture Sequence Memory, Picture Vocabulary, and Speeded Matching tests.
  • For those age 7+ there is a Total Cognition Composite score that is the sum of the Crystalized Composite (Picture Vocabulary and Oral Reading Recognition tests) and Fluid Composite (Dimensional Change Card Sort, Flanker, Picture Sequence Memory, List Sorting, and Pattern Comparison tests) scores.
  • Supplemental tests not used in the calculation of the composite scores can be used to better understand the participant’s cognitive functioning.
  • Results can be accessed through a Score Report or .CSV file once the assessment has been completed.
  • The NIHTB-CB was designed to be quick, reliable, and easy to administer.
  • The instrument uses IRT and CAT to assess constructs quickly

Content Validity

The Cognition Battery (CB) team selected the subdomains of attention, executive function, episodic memory, language, working memory, and processing speed based on two Requests for Information (RFIs) that were solicited online to obtain the input from 293 experts. The RFIs were then followed-up by telephone interviews of a subset of 44 experts. After selecting the specific tests for the subdomains, the NIH Toolbox was presented to an expert advisory panel who provided written critiques of the subdomains and instruments that were reviewed and addressed by the CB team. Lastly, several conference calls were conducted with 16 expert consultants to present the version of the CB created for validation testing and to invite feedback prior to initiating the validation study (Weintraub et al., 2013a).

Cut-Off Scores

Brain Injury: (Tulskey et al, 2017; n = 182 (mild or moderate, n = 83 or severe, n = 99); mean age = 38.6 (17.4) years; mean time since TBI = 5.8 years (5.6) years).

  • 16th percentile (score ≤ 40) is the cutoff for a low score. Complicated mild/moderate TBI and severe TBI respectively had individuals with 59% and 75% of individuals have one or more low scores.  Normative base rate of 46% suggests that .54 specificity is poor.

The Cognition Battery (CB) team selected the subdomains of attention, executive function, episodic memory, language, working memory, and processing speed based on two Requests for Information (RFIs) that were solicited online to obtain the input from 293 experts. The RFIs were then followed-up by telephone interviews of a subset of 44 experts. After selecting the specific tests for the subdomains, the NIH Toolbox was presented to an expert advisory panel who provided written critiques of the subdomains and instruments that were reviewed and addressed by the CB team. Lastly, several conference calls were conducted with 16 expert consultants to present the version of the CB created for validation testing and to invite feedback prior to initiating the validation study (Weintraub et al., 2013a).
