Developmental Item Nonresponse Code

Encode explicit item presentation, response and decline states without converting nonresponse into a developmental score.

Description

Distinguish unpresented, recorded-response, declined and no-response item states.

Developmental research records separate actual observations, coder presence, task versions, response states, caregiver reports and exposure counts. Calendar age differs from developmental status, while a symbol match or parent-teacher rating gap is only a recorded comparison. Pseudonyms and supplied source labels do not themselves protect identity or validate evidence.

Distinguish unpresented, recorded-response, declined and no-response item states.

When to use this tool

Use Developmental Item Nonresponse Code when you already have presented, responseObserved, declined and need to distinguish unpresented, recorded-response, declined and no-response item states.

How to use the tool and how it works

  1. Enter presented, responseObserved, declined. Use the units and conventions below.
  2. Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
  3. Read code. Use the output convention below.

Require responseObserved/declined to imply presented and forbid both true; choose not-presented, response-recorded, declined or no-response in that order.1

Input fieldMeaning and unitsAccepted input

}

Limitations and assumptions

  • No behavior, intent, ability, diagnosis or appropriate missing-response treatment is inferred.
  • 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 the complete study or assessment method, observation records and context for developmental interpretation. Review task adaptations, reporter perspectives and data protection together; local counts, time gaps and status labels do not establish ability, diagnosis or suitable support.
