Survey Analysis

The 722-record file appears fully populated under a literal null check. Looking at the recorded values reveals 50 entries marked −9 in 20 rows. Their interpretation requires the published codebook.

01 / COUNT WHAT IS IN THE FILE

No CSV cells are null.
But 20 records contain −9.

The semicolon-delimited file uses decimal commas, and 50 cells contain the code −9. These are observed values, not automatically validated missing responses.

LITERAL CSV NULLS

0The original CSV contains no parsed null cells.

CELLS CODED −9

50Original values are preserved, not overwritten.

RECORDS WITH −9

20Records affected by at least one observed −9 code.
✳

The audit in one minute: The dataset must first be parsed with the correct delimiter and decimal convention. A labeled sensitivity check can then study −9 as potentially unavailable without changing the underlying file.

Two ways to count completeness.

Toggle between literal CSV nulls and entries coded −9. This reveals recorded special codes; it does not establish their meaning without checking the original codebook.

AUDIT COUNTS · PRESERVED ORIGINAL DATA

0

Selected indicator

Indicator A0
Indicator B0

Comparable counts only within each definition. A switch reveals the preserved observations, not a cleaned or imputed dataset.

The input CSV has no literal nulls under the documented parser. A standard null count therefore returns zero.

03 / INTERPRET WHAT SURVIVES

Scoring needs verification
before interpretation.

A diagnostic HA03 internal-consistency calculation yields α = 0.248 on raw item directions. Without validated scoring and reversal rules, it is not a final reliability estimate or a clinical conclusion.

THE LIMIT OF A SIMPLE MISSING-CELL CHECK
Literal missing count0

A conventional CSV-null check reports none.

−9 code inventory50

Observed codes requiring instrument-specific interpretation.

The -9 meaning and HA03 scoring rules remain unconfirmed from the uploaded CSV alone. No clinical or causal conclusion is claimed.

01 / EXPLORATORY

The file format matters

What we found → 722 records and 36 variables parse correctly only with semicolon delimiters; comma decimals require a separate option.

What to do → Import using the source-specific delimiter and decimal configuration.

02 / EXPLORATORY

Encoded missingness changes the audit

What we found → The file contains zero literal nulls but 50 -9 cells spread across 20 records.

What to do → Preserve -9 and verify its meaning against the published codebook before recoding.

03 / EXPLORATORY

Internal consistency is not validation

What we found → The raw-direction 12-item HA03 coefficient alpha is 0.248 for 711 complete cases under a -9-unavailable sensitivity assumption.

What to do → Obtain scale keys and investigate multidimensionality before reporting a wellbeing score.

04 / EXPLORATORY

Age-related patterns are exploratory

What we found → Age spans 12 to 85 and a raw HA03 item mean differs modestly across an explicitly chosen age-40 split.

What to do → Avoid clinical or causal conclusions until variable definitions and scoring are verified.

DATA LIMITATIONS · UNRESOLVED
  • The study dataset is published with a separate codebook, but the codebook was not part of the uploaded files and the original variable labels are not embedded in CSV.
  • The -9 code appears in multiple questions; the sensitivity calculation assumes it denotes an unavailable response, but the original CSV remains unchanged.
  • HA03 reliability is computed on raw directions and complete cases; its score semantics and reverse coding are not established. No clinical diagnosis or outcome score is inferred.
  • The survey has no participant identifier or repeated-measures index; one row per respondent is assumed, not externally verified.
  • Observational cross-sectional results cannot support causal claims.
