DVI-SHORT FORM

The DVI-Short Form is a brief, easily administered and automated (computer-scored) adult domestic violence offender screening instrument or test. The DVI-Short Form consists of 76 items and takes 15 to 20 minutes to complete.

The DVI-Short Form evolved from the Domestic Violence Inventory (DVI) and contains variations of the six DVI scales. The DVI-Short Form assesses attitudes and behaviors important in domestic violence offender profiling. Paper-pencil test administration takes on average 17 minutes, and tests are computer-scored on-site within 2˝ minutes. The DVI-Short Form was developed specifically for domestic violence offender evaluation. It is much more than just another alcohol and drug test; it measures important attitudes and behaviors missed by other tests.

DVI-Short Form Scales (Measures)
1. Truthfulness Scale 3. Alcohol Scale 5. Control Scale
2. Violence Scale 4. Drugs Scale 6. Stress Coping Abilities

At one sitting of approximately 15 to 20 minutes' duration, staff can acquire a vast amount of information. The DVI-Short Form collects information on offender acting out (violence), controlling tendencies, substance abuse and stress coping abilities. Early problem identification facilitates timely intervention and improved outcome.

Reliability and Validity

The DVI-Short Form has a proprietary built-in database that insures inclusion of all administered tests in a confidential (no names) manner. Tens of thousands of DVI and DVI-Short Form tests' data are represented in the DVI database. These reliability, validity and accuracy statistics are reported in the document titled "DVI: An Inventory of Scientific Findings," which can be read by clicking on the “DVI Research” link in the links table on the home page. This research also presents the impressive correlation coefficients between DVI scales and their analogous DVI-Short Form scales.

In this analysis, Domestic Violence Inventory (DVI) scales were correlated with analogous DVI Short-Form scales. Pearson’s r correlation coefficients can range from zero to 1, where zero means there is no association between variables and 1 means that two variables are perfectly correlated. As shown in the following table, correlation analysis of DVI scales with DVI-Short Form scales all yielded coefficients very close to 1.0. This is to be expected because only the statistically strongest items in the DVI were selected for inclusion in the DVI-Short Form. Thus, the DVI-Short Form scales are close approximations to analogous DVI scales.

The DVI-Short Form scales correlate highly significantly with DVI scale scores.

For domestic violence offender assessment, test users now have a choice: DVI or DVI-Short Form.

Internal consistencies (coefficient alphas) for DVI-Short Form scales are reported in the following table for 5,416 domestic violence offenders assessed in the year 2010.

All DVI-Short Form scales have alpha coefficients well above the professionally accepted standard of .75 and are highly reliable. All coefficient alphas are significant at the p<.001 level.

Early DVI studies used criterion measures and were validated with other tests, e.g., Minnesota Multiphasic Personality Inventory (MMPI) L-Scale and F-Scale, 16PF, MacAndrews, MMPI Psychopathic Deviate, Treatment Intervention Inventory, SAQ-Adult Probation III, etc. Much of this research is summarized in the document titled "DVI: An Inventory of Scientific Findings." All DVI scales correlate significantly with corresponding DVI-Short Form scales.

It's reasonable to conclude that the Domestic Violence Inventory (DVI) and DVI-Short Form are evidence (reliability, validity, accuracy, scale correlations, etc.) based.
