Scientific safeguard
Qualified assessment is authoritative; chronology remains supporting evidence.
Praxis separates source-stated method or instrument changes from automated differences in CDC/NCHS method text. The qualified harmonization assessment below is the researcher-facing conclusion; method chronology explains the underlying evidence and does not override that adjudication.
Variable-by-variable chronology
Qualified harmonization assessment and indexed evidence
Each variable first shows the current qualified assessment used by Study Builder, followed by cycle-specific source evidence and method chronology.
AUQ153Compatible with harmonization
In the past 2 weeks, how often {have you/has SP} worn a {hearing aid and/or personal sound amplifier and/or cochlear implant}? If unsure, provide your best estimate of the average amount of time {you have/he has/she has} worn {your/his/her} {hearing aid, and/or personal sound amplifier, and/or cochlear implant}.

Qualified Praxis harmonization assessment
Compatible with harmonization · moderate confidence
No blocking method discontinuity is identified inside the selected cycle span, but one or more longitudinal changes require explicit harmonization conditions before pooling.
Evidence provenance: Praxis automated inference from indexed CDC/NCHS evidence
Relevant boundaries: 2017-2018 → 2017-2020
