1. Why use Behavior Data Systems tests? In addition to alcohol and drugs, Behavior Data Systems (BDS) tests gather other valuable information. All BDS tests contain a Truthfulness Scale to determine the amount of test taker denial, minimization and faking. And, each test varies according to the client population being evaluated. Consequently, BDS tests measure important behaviors missed by other tests. BDS has different tests for different client populations and different evaluation purposes. BDS tests are designed for drug courts, adult and juvenile general population courts, probation departments, corrections (prisons), parole departments, sex offender evaluations, DUI/DWI offender screening, violence (lethality) assessment, anger management programs, shoplifter testing, substance abuse treatment, counseling programs and other assessment settings. Visit BDS' test list page for more specific information on tests that you are interested in.



2. How do these testing systems work? Behavior Data Systems (BDS) test users are registered and may purchase diskettes which contain 25 or 50 test applications. Windows applications require a one-time installation procedure after which the 25 or 50 test data diskettes are used. Training manuals are provided free. Support services are available by e-mail, telephone and fax. Clients can complete the tests on the computer's screen or using the paper/pencil method with the answers manually entered into the computer by the evaluator at their convenience. When all test applications contained on a diskette are used, diskettes are returned to BDS. Prior to returning a diskette, the "delete names" option can be used to ensure confidentiality and compliance with HIPAA (federal regulation 45 C.F.R. 164.501). Test data and demographics are retained for ongoing research. Data on returned diskettes is downloaded into that test's expanding database for annual analysis. And, annual summary reports can also be provided. Ongoing database research ensures quality control. Annual test program summaries provide for program self-evaluation.



Test users that want to test over the internet should visit www.online-testing.com . You can purchase tests as you need them. This eliminates expensive testing inventories. BDS has exclusively contracted with Online-Testing to provide BDS tests online at $9.95 (U.S. currency) per test. Volume discounts are available for clients that administer over 800 tests a year. For more Online-Testing information e-mail info@online-testing.com .



3. Who can use these tests? A wide variety of staff uses evaluation, assessment and screening instruments. Applications range from troubled youth programs through pre-employment screening and chemical dependency treatment. Users include, but are not limited to, school personnel, counselors, DUI/DWI providers, probation officers, private practitioners, parole officers, juvenile and adult courts, diversion programs, EAP's, HMO's and other professionals. Training manuals and related materials are provided. Tests assess client risk and need in each of the scales (measurements) that comprise the tests. They produce risk-related working hypothesis and are to be used by experienced staff. These tests do not diagnose. BDS registers its test users and only registered users are allowed to administer its tests.

4. How can you tell if the person taking the test was truthful? It would be naive to assume everybody answers all test questions honestly. That's why  Behavior Data Systems, Ltd. (BDS) uses Truthfulness Scales and Truth-Corrected scores. The Truthfulness Scale determines how honest the person was while completing the test. The Truthfulness Scale detects denial and faking. Error of measurement associated with untruthfulness is identified and applied to each test's scale scores, resulting in Truth-Corrected scores. Truth-correcting is standardized on the test population. Raw scores may only reflect what the person being tested wants you to know. Truth-Corrected scores reveal what the test taker is trying to hide. Truth-Corrected scores are more accurate than raw scores. The Truthfulness Scale is discussed on each test webpage.

5. How can you test the reading impaired? Behavior Data Systems, Ltd. (BDS)  tests are available in English and Spanish. Reading levels typically vary around the 5th or 6th grade. "Short-Form" versions of several tests have been developed for reading impaired assessment. Many BDS tests are now available in the Audio (Human Voice) Reading test administration mode. This option is new and innovative. The client sits before the computer with earphones on. Earphones ensure clarity while eliminating distractions. The "arrow keys" allow the client to switch back and forth between questions and answers. As each question or answer is highlighted, it is read to the client. The client can go back and forth as many times as needed. When the client selects an answer, the program advances to the next question. Reading can be in any language, such as English, Spanish or Native American. This innovative approach to reading impaired evaluation resolves most bilingual, cultural and reading impaired screening problems.


6. How is confidentiality protected? BDS tests are used internationally in several countries, such as, Canada, the United Kingdom and the United States. And, there has never been a confidentiality problem. The confidentiality of the test taker is insured and compliance with HIPAA (federal regulation 45 C.F.R. 164.501) with the "delete client names" option. Before returning a used diskette to BDS,  the "delete client names" option can be used. Once test takers' names are deleted, they are removed from the diskette. Demographics and test data are retained for subsequent database analysis and annual program summary. The "delete names" option is explained in each test's "Orientation & Training Manual" and "Computer Operating Guide."


7. Are these tests reliable and valid? Correlations between a test and criteria are called validity coefficients and concurrent validity. These types of validity have been demonstrated with each test and a variety of criteria. The tests measure what they purport to measure. For example, the DRI-II accurately classifies DUI/DWI offenders in representative risk range classification categories. The DRI-II has been validated with other objective measures, selected MMPI scales, experienced staff judgment, polygraph exams, DUI/DWI screening instruments and other DUI/DWI tests. College students and non-DUI clients are represented in this research. Yet, the DRI-II has also been standardized on over one million DUI/DWI offenders. As concluded by NHTSA (National Highway Traffic Safety Administration) in DOT HS 807 475, "The DRI-II appears to be by far the most carefully constructed DWI test . . . Reliability is well established and validity is based on the DRI-II's relationship to other established measures." Continuing, "In settings where it has been adopted as the primary screening instrument for processing convicted drunk drivers, substance abuse counselors have reported that it improves the quality of their decisions while making their task less time-intensive." Reliability studies demonstrate impressive reliability coefficients.

Each test's webpage has a link to that test's reliability, validity and accuracy research.  In some cases a specific test-related study is presented, whereas in other cases a test's "Inventory of Scientific Findings" research is presented.  If additional research is desired, interested parties should contact Behavior Data Systems.

New tests are introduced via field tests. And, upon standardization, each test's database continues to expand with each test that is administered. New tests have smaller databases than established tests. Database research provides a cost efficient approach to sustaining ongoing research on a test-specific basis. Sometimes, a scale may be standardized with one test, incorporated in another test for subsequent standardization on a different population. For example, the Stress Coping Abilities Scale has been incorporated in several of our assessment instruments, and its statistical properties (reliability, validity, etc.) continue to be very impressive.

BDS continues to support independent research. Students are encouraged to utilize these tests in their masters studies and doctoral dissertations. Prior to participating, BDS requires a letter of intent specifying the name, address and telephone number of the doctoral supervisor and/or committee chairman. A research discount can be available for approved research conducted by qualified independent scientists. BDS tests' demonstrated reliability, validity and accuracy provide a sound empirical basis for decision making.


8. What are the advantages of a built-in database? Test software is designed with the capability to save the data, from each test that is administered, in a confidential (no names) manner. This procedure allows continued expansion of the test database with each test that is scored. Databases permit research opportunities that were not possible before. For example, BDS' DRI-II database constitutes one of the most extensive databases ever gathered in the DUI field. Databases permit ongoing research as well as annual statewide program summary -- with no additional imposition on staff time and at no additional cost. Until now, many agencies have lacked the technical capability and budget necessary for database analysis and summary. Ongoing database research ensures meaningful quality control. Annual summary reports provide program self-evaluation.

Built-in databases are an important feature of BDS' tests.  Consequently, databases are discussed frequently in the following webpages.


9. Are these tests expensive? By most psychometric standards, these tests are not expensive. BDS' test unit fee is $9.95 (U.S.A.) per test. BDS' proven research continues to deliver the highest assessment quality, at remarkably affordable prices. Test unit fees are not only nominal, but everything else is included free. Included at no additional cost are test booklets in English and Spanish, computerized human voice reading of tests, staff orientation and training manuals, ongoing research, annual summary reports and support services.

10. Risk Ranges explained:   BDS tests determine client risk by a series of equations, which classify clients according to four risk ranges. These risk ranges and the percentages of clients expected to fall in each risk range are as follows: low (zero-39 th percentile or 39%), medium (40-69 th percentile or 30%), problem (70-89 th percentile or 20%) and severe problem (90-100 th percentile or 11%). A problem is identified when a client's scale score is at or above the 70 th percentile. These percentages were initially derived from available literature. Subsequently they have been endorsed by our peers and test users across the United States.



SCALE RANGES
Risk
Category
Risk Range
Percentile
Total
Percentage
Low Risk 0 - 39% 39%
Medium Risk 40 - 69% 30%
Problem Risk 70 - 89% 20%
Severe Problem 90 - 100% 11%



Validity analyses support the use of these risk ranges. Problem risk (70 th percentile and above) identifies at least 98 percent of clients who have problems. In these analyses, clients who have had treatment are assumed to have problems. These clients are compared to clients who have not had treatment (no problem). Within these two groups, clients who scored at or above the 70 th percentile are compared to clients who scored at or below the 39 th percentile (low risk). In every analyses studied, at least 98 percent of the clients who had treatment scored at or above the 70 th percentile. These findings support the 70 th percentile as the threshold for identifying problems.

Classifying clients according to pre-defined risk ranges provides an efficient and workable solution to the complex problem of determining client risk. In this way risk range classification accuracy can be determined. The percentages of clients falling into each risk range should closely approximate these predicted (cognitively established) risk range percentages. All BDS tests are demonstrated to be accurate within two or three percent of predicted risk range percentages.
