Can be used with normal adults and with individuals who have a suspected or diagnosed psychiatric disorder.

 

Purpose:                      Comprehensive assessment of normal and abnormal personality traits

Age range:                   18 to 74 years

Admin:                        Self-report; Individual or group

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

Scoring time:               15-20 minutes

 

The 375-item 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).

 

Features and benefits

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 require a 4th-grade reading level.

Both tests demonstrate internal consistency reliability and concurrent validity.

 

Test structure

The OMNI must be scored using OMNI software, which is included in both OMNI kits. The tests can be administered on-screen (using a Counter Serial Number), or you may handenter responses 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.
