Scale Overview & Construct

The extended public-domain 100-item Big Five personality marker set (20 items per domain).

100-Item Scale Likert Self-Report Dimensional Breakdown Server-Side Validated

Purpose & Measurement Objectives

This is the extended, 100-item public-domain measure of the Big Five personality domains — Extraversion, Agreeableness, Conscientiousness, Emotional Stability, and Intellect — using 20 items per domain instead of the classic 50-item version's 10. Taking it gives you a more precise domain-level Big Five profile than the 50-item marker set, while still not breaking each domain down into narrower facets.
