BDSLtd.com - Adolescent Chemical Dependency Inventory -----------------------------

All ACDI 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 validity studies used criterion measures and were validated with other tests, e.g., Minnesota Multiphasic Personality Inventory (MMPI) L and F-Scales, 16PF, Treatment Intervention Inventory, MacAndrews, Juvenile Profile, experienced staff ratings, etc. Much of this research is reported in the document titled "ACDI: An Inventory of Scientific Findings." To go directly to this research, click on the ACDI Research link.

The ACDI-Corrections Version II is a corrections version of the ACDI where the Violence Scale was added, but the other scales remained the same. Pearson Product-Moment correlation coefficients between ACDI scale scores and ACDI-CV II scale scores are presented in the table below.

Two different samples of juveniles were used in this correlation analysis, and each youth took only the ACDI or the ACDI-CV II. To test the correlation between scale scores, the data for each scale was sorted in ascending order. This type of correlation was used because different respondents took different tests. But, because the scales and respondents were similar, the correlations are meaningful. There were 2,084 youths included in this analysis (1,042 for each test). Such high correlation coefficients demonstrate that ACDI and ACDI-CV II scales are reliable and valid.

Some people advocate fully automated assessment; Behavior Data Systems does not. The ACDI is to be used in conjunction with experienced staff judgment. Experienced evaluators should also interview the youth. For these reasons, the following statement is contained in each ACDI report: "ACDI reports are confidential and should be considered working hypotheses. No decision should be based solely upon ACDI results. ACDI results are to be used in conjunction with experienced staff judgment."

The Truthfulness Scale measures how truthful and open the juvenile was while completing the ACDI. This scale identifies denial, problem minimization and faking. Many troubled youth attempt to minimize their problems. A Truthfulness Scale is a necessary component in contemporary juvenile assessment. The ACDI Truthfulness Scale has been validated with other tests, truthfulness studies and the Minnesota Multiphasic Personality Inventory (MMPI) L and F-Scales. It consists of a number of items that most juveniles agree or disagree with. This important scale has been demonstrated to be reliable, valid and accurate. Much of this normative research is reported in the document titled "ACDI: An Inventory of Scientific Findings."

Truth-Corrected scores have proven to be very important in enhancing assessment accuracy. This proprietary truth correction program is comparable to the MMPI K-Scale correction methodology. The ACDI Truthfulness Scale has been correlated with the other four ACDI scales. The Truth Correction equation converts raw scores to Truth-Corrected scores. Truth-Corrected scores are more accurate than raw scores. Raw scores reflect what the juvenile wants you to know. Truth-Corrected scores reveal what the juvenile is trying to hide.

Adjustment Scale: Measures the youth's ability to adapt, conform and function. This scale recognizes personal and social stressors at home, school and in authority relationships. It incorporates personal and social forces involved in adapting to one's environment.

Distress Scale: Measures the youth's experienced pain, suffering, anxiety and depression. The blending of symptom clusters is clear in the definition of dysphoria, i.e., a generalized feeling of anxiety, restlessness and depression. Distress incorporates unhappiness, dissatisfaction, worry, apprehension, etc. The Distress Scale also incorporates items symptomatic of anxiety and depression. Distress has broad applicability in adjustment, intervention, counseling and outcome.

More than just another alcohol or drug test. In addition to alcohol and drugs, the ACDI assesses other important areas of inquiry like truthfulness, distress and adjustment. The ACDI is designed specifically for juvenile (male and female) assessment. It provides the information needed for understanding juvenile attitudes and behavior. An ACDI example report can be viewed by clicking on the ACDI Example Report link.

Three ways to give the ACDI: The ACDI can be administered in three different ways: 1. Paper-pencil test booklet format is the most popular testing procedure. English and Spanish test booklets are available. 2. ACDI tests can be given directly on the computer screen. Some youth programs dedicate computers for on-screen testing. And, 3. Human voice audio is available for English and Spanish speaking youths. This involves a computer and a headset. The juvenile uses the up-down arrow keys. As the juvenile goes from question to answer with the arrow key, that question or answer is highlighted on the monitor (screen) and simultaneously read to the juvenile. These three administration modes are discussed in the "ACDI: Orientation and Training Manual." Each test administration mode has advantages and some limitations. Behavior Data Systems offers these three test administration modes so test users can select the administration mode that is optimally suited to their needs.

Reading Impaired Assessment: Reading impaired juveniles represent 20+ percent of youths tested. This represents a serious problem to many other juvenile tests. In contrast, Behavior Data Systems has developed a proprietary alternative for reading impaired assessment, which is termed "human voice audio."

Human Voice Audio (in English or Spanish) helps resolve many reading, along with cultural difference, issues. Passive vocabularies are often greater than active vocabularies. Hearing items read often helps reduce both cultural and communication problems. As discussed earlier, "human voice audio" test presentation requires a computer, earphones and simple instructions regarding how to operate the up-down arrow keys located on the computer keyboard. Without this "human voice audio" option, a juvenile screening program could be limited.

Confidentiality: Behavior Data Systems encourages test users to delete juvenile names from diskettes before they are returned to Behavior Data Systems. This proprietary name deletion procedure involves a few keystrokes. Once juvenile names are deleted, they are gone and cannot be retrieved. Deleting juvenile names does not delete demographics or test data, which is downloaded into the ACDI database for subsequent analysis. This 'name deletion' procedure insures juvenile confidentiality and compliance with HIPAA (federal regulation 45 C.F.R. 164.501).

Test Data Input Verification: This proprietary program allows the person that inputs the test data from the answer sheet into the computer to verify the accuracy of their data input. In brief, test data is input twice, and any inconsistencies between the first and second data entries are highlighted until corrected. When the first and second data entries match or are the same, the staff person may continue. Use of this data entry verification procedure is optional, yet it is strongly recommended by Behavior Data Systems.

Inventory of Scientific Findings: Much of the ACDI research has been gathered together in one document titled "ACDI: An Inventory of Scientific Findings." This document summarizes ACDI research chronologically -- as the studies were completed. This rather innovative chronological reporting format was established largely because of the ACDI database, which permits annual database analysis of all tests administered. It also allows the reader to observe the evolution of the ACDI into its current state-of-the-art position.

Staff Training: Behavior Data Systems' staff is available to participate in ACDI training programs scheduled by test users in the United States. Large departments/agencies or statewide programs often are interested in ACDI staff training. Certificates attesting to training completion are provided.

Staff training is also provided on Fridays at Behavior Data Systems' Phoenix offices from 8:30 a.m. to 11:30 a.m. or from 1:30 p.m. to 4:30 p.m. These training sessions are free. To participate, contact Behavior Data Systems at least ten days in advance. Participation is on a first call, first scheduled basis.

"What Users Are Saying..."

"The Adolescent Chemical Dependency Inventory (ACDI) format is focused, sequential, and easy to read. The over-lay between the print-out and staff assessment has been a perfect fit. The staff response is 'right-on-target.' The scope of the analysis is broad, but concise. Our tested population falls into a normal, bell-curve distribution. The diskette allows us to give a same week guarantee, same day probability, and same hour feedback appropriate for the identified problems. Finally, the option for telephone consultation is of significant value if or when needed - which for this office has been perhaps twice over the past eleven months (in a word or two - its trouble free!)."

Porter County Juvenile Probation Office, Indiana

"We have been using the Adolescent Chemical Dependency Inventory (ACDI) in our standardized youth intake evaluations for two years now. The ACDI has had many positive advantages to our clients, staff and in terms of our mission, i.e., to provide the highest quality of service to those in need at affordable prices. The availability of test results within the same day enables us to focus our interviews and thereby save significant staff time. Test results are summarized in an easily understood manner regarding our client's problems, situation and needs. Client risk levels are summarized at a glance and recommendations are both relevant and helpful. This objective and reliable information does provide us with a 'sound basis for decisions making.' The ACDI shortens our intake procedures, aids us in cutting through denial and facilitates intervention."

"I am writing to indicate how pleased we are with the ACDI. This screening instrument provides us with an enormous amount of invaluable information at a fraction of the cost of any alternatives. As you know troubled youth with a strenuous eight day program in the Northern Flinders Ranges and a reliable initial screening program for prospective participants is essential . . . Over time the ACDI will allow us to develop a much better psychological profile of the youth who experience Operation Flinders."

Operation Flinders, National Curriculum & Training, Australia

"I received the ACDI summary report as requested earlier this month, and wanted to thank you for not only your prompt response but also the information the report itself contains.

It is very difficult for small court systems, like ours, to have the means to compile statistical data on issues other than those which are legislatively mandated. So many times, needed data, such as which your summary covered, is unavailable due to the inability of the system to have the financial resources or technical knowledge base needed. The summary report gives me the ability to now approach community leaders with hard data confirming demographic trends and treatment needs that I am aware of but could not substantiate. Now, future treatment planning that would have not occurred because of lack of data will occur.

Again, thank you for making the summary report available as part of the cost of the instrument itself. We, at TASC, will continue to use the assessment instruments developed by your company and will also continue to recommend them for use in future Ohio Juvenile TASC programs."

Scale Interpretation: There are several levels of scale interpretation ranging from viewing the ACDI and the ACDI-Corrections Version II as self-reports to interpreting scale elevations and scale interrelationships. A discussion of scale interpretation is presented in the ACDI-Corrections Version II webpage.

Test Unit Fee (Cost): ACDI cost information can be reviewed by clicking on the Test Unit Fee (Cost) link. There is only the one cost or charge, and that is the test unit fee. Everything else is included at no additional cost to the test user. This includes test booklets, answer sheets, training manuals, upgrades, ongoing database research, annual summary testing reports, staff training, and support services. Do not be misled by some test publishers' à la carte pricing like separate costs for each test administration as well as for each of the test-related items listed above. Instead of asking for the test administration cost, ask for the total cost involved in using a test. We believe Behavior Data Systems' one test unit fee is very affordable.

Free Examination Kit: A 1-test demonstration diskette is available on a 30-day cost free basis. Demo diskettes are in Windows format. The Examination Kit includes a 1-test demo diskette, installation CD (with instructions), test booklet, answer sheet and some descriptive materials. Behavior Data Systems, Ltd. does want the test booklet and diskette returned within 30 days.
