Violation Analysis Inventory

The Violation Analysis Inventory (VAI) is a brief, easily administered and automated (computer scored) test specifically designed for use with defendants convicted of moving violations. The Violation Analysis Inventory (VAI) consists of 105 items and can be completed in 15 to 20 minutes. The VAI has five (5) scales (measures): 1. Truthfulness Scale, 2. Driver Risk Scale, 3. Self-Esteem Scale, 4. Attitude Scale, and 5. Stress Coping Abilities Scale.


1. Truthfulness Scale: The Truthfulness Scale measures how truthful the client was while completing the test. This scale identifies self-protective, guarded and defensive people who minimize or even conceal information. The VAI identifies faking.

2. Driver Risk Scale: Measures the defendants driver risk independent of substance abuse. Some people are simply irresponsible or aggressive drivers. This scale identifies driver risk.

3. Self-Esteem Scale: This scale reflects a person's explicit valuing and appraisal of self. It incorporates an attitude of acceptance-approval versus rejection-disapproval. The Self-Esteem Scale reflects how a person perceives themselves.

4. Attitude Scale: Identifies negative outlooks characterized by resistance, entitlement, oppositional disposition and un-cooperativeness. Positive attitude change is a prerequisite to behavior change. This scale identifies positive or negative features of one's attitude.

5. Stress Coping Abilities Scale: This scale measures how well the applicant copes with stress, tension and job pressure. Stress exacerbates defendant problems and contributes to mental health and adjustment problems.

The Violation Analysis Inventory Training Manual provides an in depth discussion of the Violation Analysis Inventory and how it works. To review the VAI Training Manual click on this VAI Training Manual link.

The VAI is a proprietary self-report assessment instrument that is completed by the defendant individually or in group testing settings. There are no forms or questionnaires to be completed by the staff. The VAI is scored and interpreted by the computer, which generates VAI reports on-site.
