CORRELATION COEFFICIENTS
DRI-II AND SHORT FORM CORRELATIONS

DRI-II Short Form scales correlate highly significantly with comparable DRI-II scales. Correlation coefficients between DRI-II and DRI-II Short Form scales for 6,394 DUI/DWI offenders are:

Pearson Product Moment Correlation Coefficients demonstrate a very high correlation between DRI-II and comparable DRI-II Short Form scales. These correlation coefficients are so high that it is safe to conclude that the DRI-II Short Form scales measure essentially the same attitudes/behaviors that are measured with the comparable DRI-II scales. A correlation coefficient of zero refers to no relationship between variables; whereas, a correlation coefficient of 1.0 refers to a perfect relationship or correlation. In the above table, DRI-II Short Form scale items were correlated against the DRI-II scales in this sample of DRI-II data. DRI-II Short Form scales are subsets of DRI-II scales (same or similar items are in both tests), and they are shown to be highly correlated with the DRI-II scales. Along with having fewer test items per scale, the DRI-II Short Form does not include the Stress Coping Abilities Scale. For DUI/DWI offender assessment, test users now have a choice: DRI-II or DRI-II Short Form.

Sometimes its helpful when searching for a test that will meet your assessment needs to develop an outline of important test features and then see how a test meets this objective criteria. To help meet this need Behavior Data Systems offers a checklist that includes DUI/DWI offender test features.  Click on this Test Comparison Checklist link to view this checklist.

More DRI-II Short Form research is presented on the Behavior Data Systems, Ltd. website www.bdsltd.com.  Much of the Short Form research is summarized in the document titled:  "DRI-II: An Inventory of Scientific Findings" which can be provided upon request.  And this DRI-II Short Form Study link will take you to another Short Form study.
