What this test is

Welcome. The Mini-IPIP uses 20 statements from the International Personality Item Pool (IPIP) to assess Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness.

A 20-item Big Five short form—four items each for Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness/Intellect.

The measure

The Mini-IPIP five-factor model personality scale was developed by Donnellan and colleagues (2006). It has 20 items, each answered on a 5-point (Very Inaccurate … Very Accurate) scale. Its scores cover Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness.

What it measures

Five broad tendencies account for much of how people differ from one another. Extraversion concerns sociability, talkativeness and enjoyment of company; Agreeableness concerns sympathy, warmth and consideration for others; Conscientiousness concerns order, planning and following through; Neuroticism concerns mood swings, worry and how easily one is upset; and Openness, sometimes called Intellect or Imagination, concerns interest in ideas, vivid imagination and abstract thought. The Mini-IPIP asks about each with four short statements, such as being the life of the party or getting chores done right away.

The five domains emerged from decades of research on the words people use to describe one another, culminating in the lexical work of Goldberg (1992) and the questionnaire tradition summarized by Costa and McCrae (1992). Donnellan, Oswald, Baird and Lucas (2006) drew the twenty items of the Mini-IPIP from the longer fifty-item Big Five markers in the public-domain International Personality Item Pool (IPIP), choosing items that preserved the structure of the full set in a much shorter form.

Each domain is scored from its four items, giving five separate scores. Higher scores describe a stronger, more consistent version of the tendency; lower scores describe the opposite pole, which is not a deficit: low Extraversion describes a preference for quiet and smaller groups, and low Neuroticism describes emotional steadiness. With only four items per domain, the scores give a broad sketch rather than a detailed portrait.

The scale is used in research where time is short and in personal development as a quick introduction to the Big Five. On this site, the Big Five Aspect Scales (BFAS) split each domain into two aspects, the IPIP-NEO-120 scores thirty facets, the Big-Five Factor Markers give a fuller fifty-item version of the same domains, and the IPIP-HEXACO adds a sixth dimension, Honesty-Humility.

Nomological network

Convergently, Mini-IPIP domains relate substantially to longer IPIP-NEO/Big Five composites (e.g., Extraversion convergent r ≈ .70 and Agreeableness ≈ .52 with a 120-item IPIP-NEO representation in reported summaries of that work). Discriminantly, the five-factor pattern is reproduced rather than collapsing to a single evaluative factor, and domains show stronger same-trait than cross-trait associations with longer FFM measures (Donnellan et al., 2006). Predictively/criterion-wise, Donnellan et al. reported that despite brevity the Mini-IPIP showed criterion-related validity comparable to longer Big Five inventories for outcomes such as academic and well-being criteria examined in their multi-study package.

Validity evidence

The Mini-IPIP reproduces the Big Five factor structure and shows good convergent and discriminant validity with the NEO-PI-R and IPIP-NEO despite its brevity. It predicts job performance, academic achievement, and well-being outcomes comparably to longer Big Five inventories (Donnellan et al., 2006).

Sample report preview

The report opens with a profile of your scores on the 5 scales (Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness), drawn on a common scale so the overall shape of the profile is visible at a glance. Each scale then receives a short plain-language explanation of what a higher or lower standing describes. It closes with guidance on reading the results and on the limits of self-report.
