Name / group Date

1 Paste your draft questions

The whole clinic runs on these. Paste your group's questions as they stand now — faults and all.

Your draft questionnaire

2 Diagnose the faults

Tick the faults you spot (5.3). The two-question test: could two people read it differently? Can you name the output it feeds? If either fails, fix it.

The faults you found + your fix for each

3 Pick the scale — work backwards

Decide the analysis first, then pick the highest scale the concept honestly supports (5.4). The scale you choose is the analysis you are allowed.

Nominal categories, no order · mode, %, chi-square

Ordinal ranked, uneven gaps · median, cross-tab

Interval equal gaps (1–7 Likert) · mean, t-test, correlation

Ratio true zero · everything, incl. ratios

For each key question: concept → analysis you want → scale you'll use

4 Three AI review passes

The prompt below already includes your questions. It runs the three passes from 5.7 — wording, bias, and a persona pretest — then hands back a ready-to-field version. Copy it into any AI.
