Personome V1 Validation Plan.
What Personome will test, what counts as evidence, and what stays provisional until the data exists.
Current status
V1 is provisional. It is suitable for personal reflection, coaching conversations and product learning. It is not a clinical instrument and must not be used as the sole basis for hiring, medical, legal, financial or other high-stakes decisions.
Evidence levels
L1 · Validated on Personome data
Used only after our own studies are complete and published.L2 · Grounded in open literature
The dimension model and psychometric principles sit here in V1.L3 · Indicative hypothesis
Derived views such as stress are read as hypotheses until criterion studies are complete.Study 1: item reliability
Goal: estimate internal consistency for each dimension and inspect item-total behavior. Minimum target: enough completed profiles to identify weak items and unstable facets. Output: reliability table, item-retention decisions and limitations.
Study 2: test-retest stability
Goal: check whether scores are reasonably stable over a short interval when no major life event has occurred. Output: test-retest correlations by dimension and updated uncertainty bands.
Study 3: convergent validity
Goal: compare Personome dimensions with licensed or public-domain criterion measures selected under appropriate research/commercial permissions. Output: correlation matrix and interpretation of where Personome agrees or diverges.
Study 4: factor structure
Goal: test whether the six-dimension structure holds in Personome response data once sample size supports it. Output: factor-analysis summary, model-fit notes and any required item-bank revisions.
Derived views
Stress and other derived views remain indicative until checked against external criteria. The product should present them as hypotheses, not measurement-grade claims.
Publication rule
Results should be published whether they are flattering or not. If a study weakens a claim, the claim changes. If an item fails, the item bank changes with a new version.
IP and licensing rule
Validation may cite models and use licensed criterion instruments where permitted. Product items must remain original or public-domain/IPIP-derived; proprietary questionnaire items must not be copied or closely reworded.
