Description
Audit overlap in supplied informant coverage windows without merging clinical judgments.
Research questionnaires and interview records distinguish answered, declined, omitted, unpresented, and inapplicable items. Timing and support annotations also affect their denominators. A completeness measure or scale transformation describes those records without establishing an instrument score or a mental-health assessment.
Audit overlap in supplied informant coverage windows without merging clinical judgments.
When to use this tool
Use Informant Overlap Time Budget when you need the particular completeness, timing, polarity, or bookkeeping term for supplied research and interview records.
How to use the tool and how it works
- Enter firstMinutes, secondMinutes, sharedMinutes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read uniqueMinutes, duplicateShare. Use the output convention below.
Return uniqueMinutes=firstMinutes+secondMinutes-sharedMinutes and duplicateShare=sharedMinutes/(firstMinutes+secondMinutes), using zero for an all-zero total. Require nonnegative durations and feasible shared time.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| firstMinutes | First Minutes | Required. Finite number; minimum 0. |
| secondMinutes | Second Minutes | Required. Finite number; minimum 0. |
| sharedMinutes | Shared Minutes | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| uniqueMinutes | Unique Minutes | Required. Finite number. |
| duplicateShare | Shared time divided by gross time sum, not unique time. | Required. Finite number. |

}Limitations and assumptions
- DuplicateShare uses the gross sum rather than union time. The overlap is supplied, not reconstructed from interviews, and no clinical equivalence or reliable corroboration is inferred.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use the relevant validated instrument and its documented missing-response and scoring procedures when the task requires an assessment. Verify research annotations and timing before combining record terms.
