The International Personality Item Pool (IPIP) Big-Five model summarises how people differ on Extraversion, Agreeableness, Conscientiousness, Neuroticism and Openness. Researchers place these five domains at the centre of modern trait psychology.

This assessment presents sixty plain-language statements. You indicate the extent you agree or disagree with each one. A reactive engine scores your answers, normalises the totals and plots a radar chart so you can see where you sit on every domain.

Individuals often use the results to reflect on teamwork style or study habits; managers may discuss them during coaching sessions. Avoid high-stakes decisions based solely on a single questionnaire. Results do not constitute a clinical diagnosis.

Technical Details:

The IPIP-NEO-60 inventory uses ten-point Likert scoring collapsed into five-point integers. Each domain receives twelve items distributed across positive and reverse-scored phrasing, producing totals between 12 and 60. Higher totals suggest stronger expression of the trait.

S= ∑iposRi + ∑jneg6−Rj

Scores convert to percentage bands: Low < 33 %, Average 33–66 %, High > 66 %. Narrative interpretations explain what each band commonly means in daily life.

ParameterMeaningUnit/Datatype
EExtraversion domain score0-60 integer
AAgreeableness domain score0-60 integer
CConscientiousness domain score0-60 integer
NNeuroticism domain score0-60 integer
OOpenness domain score0-60 integer

Worked example: A respondent selects “Agree” for Item 1 (E pos) and “Disagree” for Item 6 (E neg).

Score = 4 + (6 − 2) = 8. Repeat across all items; total Extraversion = 44 / 60 → 73 % → High.

  • Self-report relies on honest, introspective answers.
  • Trait models describe tendencies, not fixed labels.
  • Reverse scoring assumes consistent interpretation of negated wording.
  • Cultural norms can shift average baselines.
  • All items answered identically (straight-lining).
  • Misreading reversed items.
  • Using the tool under extreme stress.
  • Deliberate social desirability bias.

Validation stems from Goldberg (1999) and subsequent peer-reviewed replications confirming reliability across cultures.

This questionnaire processes only non-identifiable preference data and aligns with GDPR Article 6 (1)(a) consent requirements.

Step-by-Step Guide:

Follow these steps to obtain your five-factor profile.

  1. Read each statement carefully.
  2. Select one response value from Strongly Disagree to Strongly Agree.
  3. Move through all sixty statements in any order.
  4. Review the radar chart and narrative explanations.
  5. Reflect on patterns; consider saving the summary for future reference.

FAQ:

Is my data stored?

No. Responses remain solely in your browser and vanish when you close the tab.

How long does it take?

Most people finish in about five minutes.

Can I skip questions?

Every item must be answered to generate scores, but you may answer in any sequence.

Who created the questions?

The items come from the open-source IPIP International Personality Item Pool project.

What if my scores change?

Traits can shift gradually with life experiences; retake after several months for comparison.
