Description
Flag a literal change in an aging-panel informant identifier.
Aging research distinguishes participant and informant identities, calendar-month coordinates, time-use exposure and event/censoring status. Proxy responses and missing codes carry different meanings from direct observations. Local record summaries do not establish lifespan, legal status, accessibility or appropriate care.
Flag a literal change in an aging-panel informant identifier.
When to use this tool
Use Aging Panel Informant Change Flag when checking the stated aging-study record, timing, censoring or support convention.
How to use the tool and how it works
- Enter previousInformantId, currentInformantId. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read informantChanged. Inspect informantChanged before interpreting the associated values.
Require nonempty previous/current informant IDs. Return whether they differ literally.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| previousInformantId | Previous Informant Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| currentInformantId | Current Informant Id | Required. Text; minimum UTF-16 length 1; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| informantChanged | Informant Changed | Required. Boolean. |

"informantChanged": true
}
}Limitations and assumptions
- A changed identifier does not independently establish a new person, proxy authority or a change in measurement quality.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use verified original records and suitable complete research methods; involve qualified health, accessibility or legal professionals for actual care or rights decisions.
