IPIP-AB5C Personality Circumplex

Scale Overview & Construct

A public-domain 445-item measure of 44 narrow personality facets from the AB5C circumplex model.

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

Purpose & Measurement Objectives

The IPIP-AB5C is a public-domain measure built on the Abridged Big Five-Dimensional Circumplex model, which maps 44 narrow personality facets onto the space around the Big Five domains. Rather than one score per broad domain, it gives you a score on each of 44 specific facets — from Assertiveness and Leadership to Tenderness and Tranquility — capturing fine shades of personality that sit between and around the standard Big Five traits. Taking it gives you the most granular personality facet profile on this platform, useful for spotting specific tendencies that a broader Big Five or CPI-style profile can blur together.

Governance, Boundaries & Ethical Use

Construct Boundaries & Interpretive Limitations

This is a 445-item self-report inventory covering 44 separate facets; individual facet scores are based on 5 to 14 items each, so shorter facets are less precise than longer ones. Results reflect how you currently see yourself, not an objective or clinical evaluation of personality.
