We are developing a strategy to raise the visibility of the Toolkit and promote its use by epidemiologists and other investigators. Based on Toolkit user feedback, we expect to continue to update the functionality of the Toolkit. We plan to establish a process for updating Toolkit content. As complementary and related research efforts mature, some of these measures may be incorporated into the PhenX Toolkit. For example, the Patient-Reported Outcomes Measurement System (http://www.nihpromis.org/) is developing new instruments for effectively capturing patient-provided information, and the NIH Toolbox (http://www.nihtoolbox.org/) is focused on developing new protocols for neurologic and behavioral assessments.
