Using the NIH Toolbox in special populations Considerations for assessment of pediatric, geriatric, culturally diverse, non-English-speaking, and disabled individuals

Background: In order to develop health outcomes measures that are relevant and applicable to the general population, it is essential to consider the needs and requirements of special subgroups, such as the young, elderly, disabled, and people of different ethnic and cultural backgrounds, within that population. Methods: The NIH Toolbox project convened several working groups to address assessment issues for the following subgroups: pediatric, geriatric, cultural, non-English-speaking, and disabled. Each group reviewed all NIH Toolbox instruments in their entirety. Results: Each working group provided recommendations to the scientific study teams regarding instrument content, presentation, and administration. When feasible and appropriate, instruments and administration procedures have been modified in accordance with these recommendations. Conclusion: Health outcome measurement can benefit from expert input regarding assessment considerations for special subgroups. Neurology (R) 2013; 80 (Suppl 3):S13-S19
