The nih_memory data element records responses to the prompt, or a congruently meaning prompt, "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions?". Equivalent prompts are: - "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions? (5 years of age or older)" RADx-UP - "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions?" RADx-rad - "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions? (5 years or older)" RADx-Tech - "Because of a physical, mental, or emotional condition, do you have serious difficulty concentrating, remembering, or making decisions?" RADx-DHT The values for this data element are integers that come from a list of 5 permissible integer values. The nih_memory data element is the result of the harmonization of other RADx program data elements: disability_decisions RADx-UP; memory_dis RADx-rad; memory RADx-Tech; dht_memory RADx-DHT Note that the meaning of the value 97 is context specific and depends on the subset of permissible value used by a specific study (not all studies presented the full set of permissible values documented here for this data element). Therefore, the meaning of the value 97 in an individual data record MUST be determined by referring to the original data dictionary for the non-harmonized data in that study.
