Mini-IPIP (Big Five, 20 items)

The Five-Factor Model organizes personality into five broad domains, each capturing a general tendency that shapes how a person thinks, feels, and behaves. The Mini-IPIP is a brief 20-item measure of those five dimensions — Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience — using four items per domain on a 1–5 accuracy scale. It is designed for situations where a full-length inventory is impractical, trading the facet-level detail of longer forms for a fast, well-validated read on the broad domains.

Your five Big Five domain scores, each shown with a population percentile and a 90% confidence range so you can see where you stand relative to a normative sample and how precisely each score is estimated. Each domain is a 4-item sum (range 4–20).

The normative comparison comes from Cooper, Smillie & Corr (2010), a UK internet reference sample (N = 1,470) of summed total scores on the verbatim 20-item Mini-IPIP. That sample is a self-selected online pool rather than a nationally representative survey, so percentiles should be read as a comparison against other online respondents, not the general population. The confidence range uses the standard error of measurement from the published Cronbach’s α.
