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). Derived directly from the OMNI, the 210-item 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/OMNI-IV software, which is included in both OMNI kits. The tests can be administered on-screen (using a Counter Serial Number), or you may hand enter 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.
