Purpose: Comprehensive assessment of normal and abnormal personality traits

Age: 18-74 years

Time: 60-90 minutes for the OMNI; 35-45 minutes for the OMNI-IV

Administration: Self-report; Individual or group

The 375-item OMNI Personality Inventory (OMNI) measures both normal and abnormal personality traits. Composed of seven factor scales, it assesses 25 normal traits (Normal scales) and 10 abnormal traits (Personality Disorder scales).

Derived directly from the OMNI, the 210-item OMNI Personality Inventory – Revised (OMNI-IV) measures abnormal personality traits and assesses personality disorders; it comprises 10 Personality Disorder scales.

The OMNI and the OMNI-IV must be scored using OMNI or OMNI-IV software, which is included in both the kits.

The tests can be administered on-screen (using Counter Serial Numbers), or data can be hand-entered into the software. The software generates an interpretive report that includes a broad range of information about the individual's personality characteristics and deviations from normality (using the language and typology of the DSM-IV Axis II classification of personality disorders).

Key Features

  • Personality Disorder scales are based on the DSM-IV Axis II personality disorder criteria.
  • A Variable Response Inconsistency scale identifies item response inconsistencies
  • A Current Distress scale assesses the respondent's mental state during the 7 days preceding the test date.
  • Both tests demonstrate internal consistency reliability and concurrent validity.
