Qualification Level: A
The 375-item OMNI is designed to provide clinicians and researchers with a comprehensive self-report instrument for measuring both normal and abnormal personality traits. It is composed of seven Factor scales and assesses 25 normal traits (Normal scales) and 10 abnormal traits (Personality Disorder scales). The Personality Disorder scales are based on the DSM-IV Axis II personality disorder criteria. A Variable Response Inconsistency (VRIN) scale identifies item response inconsistencies and a Current Distress (CD) scale assesses the respondent's mental state during the 7 days preceding the test date.
- For use with normal adults and individuals with a suspected or diagnosed psychiatric disorder.
- Self-report format; 10 year reading level.
- Useful in a variety of settings: psychological/psychiatric settings (inpatient and outpatient), neuropsychological assessment (e.g., head injured patients), and correctional facilities (e.g., assessing for Antisocial Personality Disorder).
- Normative sample included 1,000 community dwelling adults, ages 18-74 years, approximating U.S. census data for age and gender.
- Demonstrated internal consistency reliability and concurrent validity.
- Can be completed in approximately 60-90 minutes.
The OMNI can be administered on-screen using a Counter Serial Number, or the clinician can administer using the paper-and-pencil Test Booklet and then enter the individual's responses into the OMNI Software System. The software scores the inventory and generates an interpretive report that includes a broad range of information about the individual's normal personality characteristics and deviations from normality using the language and typology of the DSM-IV Axis II classification of personality disorders.
