Big Five source instrument
The Big Five assessment uses the public-domain 50-item IPIP Big-Five Factor Markers. The first implementation keeps the official item wording and keying rather than rewriting a scale while borrowing its evidence.
- IPIP permission and public-domain statement
- IPIP scoring instructions
- IPIP 50-item administration guidance
- IPIP Big-Five Factor Marker scoring keys
- IPIP reliability and comparison table
The explanatory score bands, profile language, examples, and page structure are PersonalityMe editorial copy. The site does not present its 0–100 display scores as percentiles and does not claim a norm sample that has not been implemented.
RIASEC foundation
RIASEC is used as a general model of six vocational-interest themes. PersonalityMe’s 60 activity prompts, score interpretation, and report wording are original product material.
Background and licensing sources reviewed during development include:
- Armstrong, Allison, and Rounds on RIASEC marker development
- O*NET Career Exploration Tools content licence
- O*NET Interest Profiler manual
PersonalityMe does not reuse O*NET Interest Profiler items or occupational data, the IIP RIASEC Markers item bank, Self-Directed Search wording, Strong Interest Inventory content, or OpenPsychometrics test wording. It does not imply endorsement by any of those organisations or products.
16-Type foundation
The four preference pairs are presented as an educational personality lens. The 48-item bank, scoring implementation, profile titles, and report wording are original PersonalityMe material. The site does not use proprietary MBTI® questions or report wording and is not an official or affiliated MBTI product.
Type descriptions are interpretive rather than diagnostic. The four-letter code summarises answers to this assessment; it does not prove a fixed psychological type.
Enneagram foundation
The nine-type model is presented as an interpretive lens on recurring motivations and coping patterns. The 90-item bank, facet labels, profile titles, scoring implementation, and report wording are original PersonalityMe material.
The current version should be treated as exploratory. It does not claim clinical validation, diagnosis, measured instinctual stacking, tritype, or a validated health-level score.
Source and correction standards
We prefer primary documentation and research papers when a claim depends on an external source. A link here documents a source or licensing decision; it does not imply that its author endorses PersonalityMe.
If a source link changes, a licence appears to have been misunderstood, or a claim overreaches the cited material, please send the page URL and concern through the contact page.
Search publishing standards
Our comparison index policy is informed by Google Search's published guidance on creating helpful, reliable, people-first content and its definition of scaled content abuse. These sources do not decide our editorial conclusions, but they reinforce the requirement that an indexable page should exist to answer a reader's question rather than merely occupy another search URL.
