Before you start

Describe yourself as you generally are now, not as you wish to be in the future. Describe yourself as you honestly see yourself, in relation to other people you know of the same sex as you are, and roughly your same age. So that you can describe yourself in an honest manner, your responses will be kept in absolute confidence. Indicate for each statement whether it is 1. Very Inaccurate, 2. Moderately Inaccurate, 3. Neither Accurate Nor Inaccurate, 4. Moderately Accurate, or 5. Very Accurate as a description of you.

What this covers

Extraversion: A higher mean reflects more endorsement of sociability and outward engagement items; a lower mean reflects more endorsement of quiet or reserved items. Neither direction is better or clinical.
Agreeableness: A higher mean reflects more endorsement of compassion and interpersonal consideration items; a lower mean reflects less endorsement of those items. Neither direction is a diagnosis or moral judgment.
Conscientiousness: A higher mean reflects more endorsement of preparation, order and follow-through items; a lower mean reflects less endorsement of those items. Context can affect both patterns.
Emotional Stability: A higher mean reflects more endorsement of calm and emotional steadiness items; a lower mean reflects more endorsement of worry, distress or mood-change items. This is not a mental-health assessment.
Intellect/Imagination: A higher mean reflects more endorsement of ideas, imagination and abstract-thinking items; a lower mean reflects less endorsement of those items. This dimension does not measure intelligence.

Who it is for

Adults who want a private, descriptive view of five broad personality dimensions.

What your result can show

The result contains five separate mean item scores from 1 to 5. It has no overall personality score, personality type, percentile, clinical range or low/high classification. Higher and lower values only describe how the published items were endorsed.

Important limitations

Scores are self-reported descriptions influenced by language, context and response style. They do not diagnose or rule out any condition, measure intelligence, or establish fixed traits. NuraCheck translations are unvalidated unless a source is identified for that locale.

A higher score does not establish a diagnosis. A lower score does not show that a condition is absent.

Evidence and permission

IPIP items and scales are in the public domain and may be used, copied, edited and translated for commercial or non-commercial purposes.

Your answers and result stay on this device. After completion, you can separately choose to upload derived scores for a private link that expires after 180 days.
