Psychometric Properties of the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) in Public First Responders

Problematic alcohol consumption is prevalent among first responders because alcohol is commonly used to cope with occupational stress and frequent exposure to traumatic incidents, making them an at-risk population for alcohol use disorders (AUD). This study investigated the psychometric properties of the Korean version of the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) among public first responders. The Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders-IV-Text Revision (SCID), AUDIT-C, AUDIT, and CAGE were administered to 222 public first responders, who were recruited by convenience sampling. One-week test–retest reliability was evaluated in a subsample (n = 24). Receiver operating characteristic (ROC) curve analyses were conducted to evaluate the diagnostic accuracy and estimate the optimal cut-off scores for any AUD and alcohol dependence. Three different analytic criteria were utilized to calculate the cut-off scores. The AUDIT-C demonstrated good test–retest reliability (intraclass correlation coefficient for test–retest reliability = 0.91) and satisfactory convergent validity. The areas under the ROC curves for any AUD and alcohol dependence of the AUDIT-C were 0.87 and 0.93, respectively. For any AUD, all three criteria suggested a cut-off score of 7.5 (sensitivity = 81.8%, specificity = 79.8%), whereas for alcohol dependence, a cut-off score of 8.5 (sensitivity = 85.7%, specificity = 86.1%) was derived from two criteria. In conclusion, the AUDIT-C demonstrated good reliability and validity and proved to be a brief and effective screening test for AUD among first responders.     

Does the Alcohol Use Disorders Identification Test–Consumption identify the same patient population as the full 10-item Alcohol Use Disorders Identification Test?

The aim of this study was to evaluate whether a computer-based 3-item version (Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]) of the Alcohol Use Disorders Identification Test (AUDIT) identifies alcohol use disorder (AUD) in the same patients as the full 10-item version in 809 women and 747 men in an anesthesiology preoperative assessment clinic. According to cutoffs used (AUDIT: 5-8 points, AUDIT-C: 4-6 points), rate of disagreement (AUDIT-positive and AUDIT-C-negative or vice versa) ranged between 4% and 31% (men) and between 4% and 19% (women). In male patients, 15% were positive for both the AUDIT (≥8 points) and the AUDIT-C (≥6 points), 7% were positive for AUDIT-C only, and 4% were positive for AUDIT only. In female patients, using cutoffs of 5 more points (AUDIT) and 4 or more points (AUDIT-C), 16% were positive for both versions, 9% were positive for AUDIT-C only, and 2% were positive for AUDIT only. The AUDIT and AUDIT-C seem to identify AUD in differing patients.     

Performance of the AUDIT in Detecting DSM-5 Alcohol Use Disorders in College Students

Background: It is critical that our alcohol screening instruments maintain their accuracy at detecting DSM-5 Alcohol Use Disorder (AUD) symptomatology. The Alcohol Use Disorders Identification Test (AUDIT) is one of the most widely used alcohol screening instruments, despite no studies evaluating its performance for detecting DSM-5 AUDs. Objectives: The present study evaluated the performance of the AUDIT in the screening of DSM-5 AUDs in non-treatment seeking college students. Methods: Participants (N = 251) were undergraduate students who had at least one binge drinking occasion in the past 90-days. Results: The AUROC value for DSM-5 AUD status in the overall sample was.779 (SE =.029; 95% CIs =.721 to.837). The AUROC values for the reference groups of any DSM-IV AUD and any binge drinker were.798 (SE =.028; 95% CIs =.742 to.853) and.827 (SE =.03; 95% CIs.768 –.886), respectively. A similar pattern of findings emerged between males and females. Gender differences emerged in the identification of AUDIT cut-off scores. A score of ≥ 8 and ≥ 9 had the best balance of sensitivity and specificity for females and males in college, respectively. Conclusion: Findings indicate that the AUDIT has a reasonable degree of diagnostic proficiency in screening for DSM-5 AUDs in college students.     

Alcohol use disorder symptoms and risk-taking behavior as predictors of alcohol-related medical events among young adults treated in emergency departments

BACKGROUND: Studies of alcohol-positive patients in emergency departments are not clear on the relationship between alcohol use disorder (AUD) symptoms and risk for injury. METHOD: Two-hundred three young adults (118 males (58%); mean age = 19.4 years) who were treated in two Level-1 emergency departments (ED) received comprehensive psychiatric interviews and completed the Alcohol Use Disorders Identification Test (AUDIT) and the Cognitive Appraisal of Risky Events (CARE). RESULTS: Males diagnosed with the AUD symptom of "drinking more or over a longer period than intended" are at greatest risk for requiring emergency care for an alcohol-related medical problem (OR = 10.8, 95% CI = 1.2,94.3, p < .04). Risk-taking behaviors increase risk for an alcohol-related medical event for both genders (OR = 2.6, 95% CI=1.1,5.6.1, p < .03). Alcohol use disorder severity related negatively to risk for experiencing an alcohol-related medical problem (OR = 0.6, 95% CI = 0.4,0.9, p < .04). CONCLUSIONS: Young adults treated for alcohol-related medical problems often exhibit DSM-IV defined symptoms of AUD and are engaging in risk-taking behaviors and should be referred for an in-depth assessment of alcohol use disorders and risk-taking activities.     

The Alcohol Use Disorders Identification Test (AUDIT) as a screening instrument for adolescents

Background

The Alcohol Use Disorders Identification Test (AUDIT) is an international screening instrument extensively employed in adult target groups. However, there is scarce information on screening with the AUDIT in adolescent populations. The purpose of this study was to determine the cut-off point for hazardous, harmful, and dependent alcohol use through the validation of the AUDIT in a Chilean adolescent sample.

Methods

The original English version of the AUDIT was translated into Spanish, using the procedure recommended by the World Health Organization. The text was then back-translated and sent to one of the original authors (Thomas Babor), who approved the translation. Students attending public schools in Santiago, Chile, self-administered the AUDIT, and those older than 15 years completed the Composite International Diagnostic Interview-Substance Abuse Module (CIDI-SAM), which served as a gold standard. Between 1 and 4 weeks after the CIDI-SAM, participants answered a second AUDIT.

Results

A total of 42 female and 53 male adolescents (mean age: 15.9 [SD = 1.2]) completed the AUDIT, with a mean score of 4.3. Reliability according to Cronbach's alpha was 0.83. Test–retest correlation was also satisfactory (intra-class correlation 0.81 [95% CI 0.73–0.87]). Analysis of the receiver operating characteristic (ROC) curve yielded cut-off points for hazardous, harmful, and dependent alcohol use of 3, 5, and 7 points, respectively.

Conclusions

The Chilean version of the AUDIT is a valid and reliable tool for identifying adolescents with hazardous, harmful, and dependent alcohol use. The suggested cut-off points make screening with the AUDIT more accurate for adolescent populations.     

An examination of the utility of the AUDIT in people with schizophrenia

OBJECTIVE: To examine the reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) compared to a structured diagnostic interview, the Composite International Diagnostic Interview (CIDI; 12-month version) in psychiatric patients with a diagnosis of schizophrenia. METHOD: Patients (N = 71, 53 men) were interviewed using the CIDI (Alcohol Misuse Section; 12-month version) and then completed the AUDIT. RESULTS: The CIDI identified 32.4% of the sample as having an alcohol use disorder. Of these, 5 (7.0%) met diagnostic criteria for harmful use of alcohol, 1 (1.4%) met diagnostic criteria for alcohol abuse and 17 (23.9%) met diagnostic criteria for alcohol dependence. The AUDIT was found to have good internal reliability (coefficient = 0.85). An AUDIT cutoff of > or = 8 had a sensitivity of 87% and specificity of 90% in detecting CIDI-diagnosed alcohol disorders. All items except Item 9 contributed significantly to discriminant validity. CONCLUSIONS: The findings replicate and extend previous findings of high rates of alcohol use disorders in people with severe mental illness. The AUDIT was found to be reliable and valid in this sample and can be used with confidence as a screening instrument for alcohol use disorders in people with schizophrenia.     

Evaluating Shortened Versions of the AUDIT as Screeners for Alcohol Use Problems in a General Population Study

Background: Efficient alcohol screening measures are important to prevent or treat alcohol use disorders (AUDs). Objectives: We studied different versions of the Alcohol Use Disorders Identification Test (AUDIT) comparing their performance to the full AUDIT and an AUD measure as screeners for alcohol use problems in Goa, India. Methods: Data from a general population study on 743 male drinkers aged 18–49 years are reported. Drinkers completed the AUDIT and an AUD measure. We created shorter versions of the AUDIT by (a) collapsing AUDIT item responses into three and two categories and (b) deleting two items with the lowest factor loadings. Each version was evaluated using factor, reliability and validity, and differential item functioning (DIF) analysis by age, education, standard of living index (SLI), and area of residence. Results: A single factor solution was found for each version with lower factor loadings for items on guilt and concern. There were no significant differences among the different AUDIT versions in predicting AUD. No significant DIF was found by education, SLI or area of residence. DIF was observed for the alcohol frequency item by age. Conclusions/Importance: The AUDIT may be used with dichotomized response options without loss of predictive validity. A shortened eight-item dichotomized scale can adequately screen for AUDs in Goa when brevity is of paramount importance, although with lower predictive validity. Although the frequency item was endorsed more by older men, there is no evidence that the AUDIT items perform differently in other groups of male drinkers in Goa.     

Assessment of binge drinking of alcohol in highly educated employees

This study evaluated the usefulness of the Alcohol Use Disorders Identification Test (AUDIT) and CAGE, a standardized screening instrument for detecting alcohol dependence in identifying binge drinking among highly educated employees. Brochures were mailed to an entire workforce inviting employees to learn about their coping strategies, stress levels, and risk for alcohol-related problems, with 228 employees providing complete data. Binge drinking in the previous 3 months was reported by 29% of the employees, with greater binge drinking reported by White employees, of mixed/other ethnic background, or younger. The AUDIT achieved a sensitivity of 35% in identifying respondents who reported binge drinking and a specificity of 98% in accurately identifying respondents who did not report binge drinking. Sensitivity using the cut-off of scoring one or more positive hits on the CAGE was 67%, and specificity was 84%. Therefore, neither the AUDIT nor the CAGE achieved adequate sensitivity, as well as specificity, as screening tools for assessing binge drinking. A more accurate method for assessing binge drinking appears to be by directly asking for the largest number of drinks consumed in a single drinking session.     

Alcohol-related advice for Veterans Affairs primary care patients: Who gets it? Who gives it?

OBJECTIVE: Most patients who misuse alcohol do not receive alcohol counseling from their providers. This study evaluated primary care patient and provider characteristics associated with receipt of alcohol-related advice and whether patients were advised to drink less or to abstain. METHOD: Outpatients from seven Veterans Affairs (VA) general medicine clinics were eligible if they screened positive for alcohol misuse, completed the Alcohol Use Disorders Identification Test (AUDIT) and answered questions about alcohol-related treatment and advice. Hierarchical logistic regression was used to evaluate patient and provider characteristics associated with patient reports of alcohol-related advice from a primary care provider in the past year. RESULTS: Among 5191 patients with alcohol misuse in the past year, 1554 (30%) reported receiving alcohol-related advice from their primary care provider during that time. Of patients advised, 73% reported advice to abstain. The likelihood of reporting advice increased as AUDIT scores increased: from 13% of patients with AUDIT scores <8 to 71% of those with scores > or =20. After adjustment for important confounders, measures reflecting the severity of alcohol misuse were most strongly associated with receipt of alcohol-related advice. Adjusted analyses also revealed increased odds of receiving advice among patients who reported liver disease, hypertension, current smoking or continuity of care. No measured provider characteristic was associated with giving advice in the fully adjusted model. CONCLUSIONS: This multisite VA study found that most patients with alcohol misuse did not receive alcohol counseling from a primary care provider. Moreover, providers predominantly offered advice to abstain, and they appeared to focus on patients with the most severe problems due to drinking or medical contraindications to drinking.     

Validation of the Alcohol Use Disorders Identification Test (AUDIT) in urban community outreach and de-addiction center samples in north India

OBJECTIVE: The Alcohol Use Disorders Identification Test (AUDIT) developed by the World Health Organization for screening disorders related to alcohol use has been shown to have robust psychometric properties. This study compared the performance of AUDIT with that of the Short Michigan Alcoholism Screening Test (SMAST) in a region of North India. METHOD: A total of 297 consecutive subjects who had used alcohol in the past year were recruited from a de-addiction center (DAC) (n = 97) and a community outreach setting (n = 200) in West Delhi. Using International Classification of Diseases, Tenth Edition (ICD-10) criteria, the relative effectiveness of the AUDIT and the SMAST in identifying alcohol-use-related disorders was assessed and compared. Internal consistency and interscale correlations were evaluated, along with sensitivity, specificity and ROC curve analyses. RESULTS: The AUDIT had very high internal reliability (alpha 0.92) in this Indian sample. There was, in general, good correlation between the total and factor scores of the AUDIT and SMAST (ranging from 0.28 to 0.97), which were higher in the community than in the DAC sample. The AUDIT (area under the curve [AUC] = 0.883) and SMAST (AUC = 0.870) were similar in detecting harmful use of alcohol. The AUDIT optimal cutoff score was 16 (sensitivity 85.3, specificity 89.4) for ICD-10 harmful use and 24 (sensitivity 69.4, specificity 87.5) for ICD-10 alcohol dependence. CONCLUSIONS: The AUDIT and SMAST seem to be comparable in their ability to screen subjects with alcohol use disorders. The AUDIT score for screening harmful use in the sample appears to be higher than previously reported. The utility of such high cutoff for screening subjects for intervention is obvious, but it is quite likely that some positive cases might be missed.     

Automated telephone screening for problem drinking

OBJECTIVE: This study assessed test-retest reliability and criterion validity for an automated version of the Alcohol Use Disorders Identification Test (AUDIT), a screening tool for alcohol-related problems. Participants' willingness to use such a system to learn about and change their drinking behavior was also assessed. METHOD: Participants were 202 callers recruited through newspaper ads and flyers asking for volunteers concerned about their drinking and willing to help test a new method of screening and referral for alcohol problems. Participants were divided into two groups. The first group of subjects recruited received the Telephone-Linked Communications (TLC)-AUDIT twice, administered a week apart. The second group received the TLC-AUDIT once and a human-administered AUDIT once, also a week apart. RESULTS: Test-retest reliability was assessed in 102 participants; the intraclass correlation of AUDIT scores between both administrations was .87; kappa for nonproblem versus problem drinking (AUDIT score of 8 or above) was .89. The validity study compared the TLC-AUDIT scores of the next 100 participants to AUDIT questions administered by a human interviewer. The intraclass correlation was .94; kappa was .75. Seventy-five percent of all participants who screened positive for problem drinking agreed they would "talk to a computer again to learn more about your drinking pattern and how to deal with it". CONCLUSIONS: Automated telephone technology can be used to administer the AUDIT instrument with high levels of reliability and validity. This technology could be used to deliver behavioral change interventions.     

Primary care validation of a single screening question for drinkers

OBJECTIVE: The aim of this study was to conduct a primary care validation study of a single screening question for alcohol misuse ("When was the last time you had more than X drinks in 1 day?," where X was four for women and X was five for men), which was previously validated in a study conducted in emergency departments. METHOD: This cross-sectional study was accomplished by interviewing 625 male and female adult drinkers who presented to five southeastern primary care practices. Patients answered the single question (coded as within 3 months, within 12 months, ever, or never), Alcohol Use Disorders Identification Test (AUDIT), and AUDIT consumption questions (AUDIT-C). Alcohol misuse was defined as either at-risk drinking, identified by a 29-day Timeline Followback interview or a current (past-year) alcohol-use disorder by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria, or both. RESULTS: Among 625 drinkers interviewed, 25.6% were at-risk drinkers, 21.7% had a current alcohol- use disorder, and 35.2% had either or both conditions. Considering "within the last 3 months" as positive, the sensitivity of the single question was 80% and the specificity was 74%. Chi-square analyses revealed similar sensitivity across ethnic and gender groups; however, specificity was higher in women and whites (p = .0187 and .0421, respectively). Considering "within the last 12 months" as positive increased the question's sensitivity, especially for those with alcohol-use disorders. The area under the receiver operating characteristic curve of the single alcohol screening question (0.79) was slightly lower than for the AUDIT and AUDIT-C, but sensitivity and specificity were similar. CONCLUSIONS: A single question about the last episode of heavy drinking is a sensitive, time-efficient screening instrument that shows promise for increasing alcohol screening in primary care practices.     

Comparison of Three Methods to Assess Binge Consumption: One-Week Retrospective Drinking Diary,AUDIT, and Quantity/Frequency

Binge consumption contributes substantially to the occurrence of alcohol-related harm. Despite its importance, binge drinking is not well defined in the literature. The present study examines the proportions of respondents identified as binge drinkers by three separate measures: a 1-week retrospective drinking diary (RD), the Alcohol Use Disorders Identification Test (AUDIT), and a quantity/frequency (QF) question. Overall, AUDIT detected the highest proportion of binge drinkers, followed by QF and RD. There was also good agreement between QF and RD, as well as QF and AUDIT. Ultimately, the measure of choice should be that which provides information most appropriate to the purposes of each study.     

Short forms of the AUDIT in a Web‐based study of young drinkers

Introduction. The Alcohol Use Disorders Identification Test (AUDIT) is under‐studied among young drinkers, as are the contributions of individual items to total AUDIT scores, and online performance of the existing briefer versions of this instrument. Design and Methods. This study examined individual items of the AUDIT, and various combinations, including the existing briefer versions, in relation to total AUDIT scores in a Web‐based study of young drinkers. A total of 167 young people aged 16–24 years old who had consumed any alcohol within the previous 7 days were recruited by both offline and online methods. Results. Considered individually, items 3, 4, 5 and 8 were predictive of the majority of the variance in total AUDIT scores in this Web‐based study. Existing briefer versions of the AUDIT do not better predict total scores than possible alternative combinations of items, for which acceptable levels of sensitivity and specificity for screening have been demonstrated. Conclusions. Short forms of the AUDIT, particularly those based only on consumption questions, require further validation study in online applications with young people.[McCambridge J, Thomas BA. Short forms of the AUDIT in a Web‐based study of young drinkers. Drug Alcohol Rev 2009;28:18–24]     

Problem drinking profiles of patients presenting to general practitioners: analysis of Alcohol Use Disorders Identification Test (AUDIT) scores for the Auckland area

AIM: To quantify the prevalence and demography of at-risk and problematic drinkers in the population attending a random selection of general practices and to compare this with similar studies. METHOD: A study examining the uptake and utilisation of the "DRINKLESS" package to 369 New Zealand general practitioners was conducted during 1995/6. The "DRINKLESS" package was developed with the World Health Organisation collaborative study for brief intervention for at-risk alcohol consumption. The package uses the Alcohol Use Disorders Identification Test (AUDIT). There were 15,670 completed AUDIT questionnaires collected during the study. These were analysed to ascertain the prevalence and demography of at-risk and problematic drinkers attending general practitioners. RESULTS: There were 16% of patients identified as having either "risky drinking" or "problematic or dependent drinking". This pattern varied according to the occupation, age and gender of patients. CONCLUSIONS: The data confirm that large numbers of patients presenting to general practitioners experience alcohol problems of varying degrees. This study also suggests that the AUDIT will have satisfactory detection rates in a primary care setting.     

Internet-based assessment and self-monitoring of problematic alcohol and drug use

A Swedish web-based service (www.escreen.se) offers self-assessment and self-monitoring of alcohol and drug use via on-line screening with the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) as well as in-depth risk assessment using extended versions of both tests (Alcohol-E and DUDIT-E). Users receive individualized feedback concerning their alcohol and drug consumption and can follow their alcohol and drug use over time in personal diagrams and by writing in an electronic diary. This study describes user characteristics, service utilization patterns, and psychometric test properties for 2361 individuals who created a valid account over 20 months starting in February 2007. Problematic alcohol use according to AUDIT criteria was indicated for 67.4%, while 46.0% met DUDIT criteria for problematic drug use. Men and women accessed the service equally, with a mean age of 23 years. Internal consistency reliability figures were 0.90 for 1846 first-time AUDIT users and 0.97 for 1211 first-time DUDIT users; among 213 second-time AUDIT users reliability was 0.93, and 0.96 for 97 second-time DUDIT users. Internet-based alcohol and drug monitoring could function as a self-help tool or as a complement to substance abuse treatment.     

Use of AUDIT for alcohol screening among emergency room patients in Thailand. Alcohol Use Disorders Identification Test.

This study evaluated the Alcohol Use Disorders Identification Test (AUDIT) against blood alcohol levels and medical diagnoses. The population under study included 695 current drinkers admitted to emergency rooms of four regional Thailand hospitals. The AUDIT positivity rate was 61% among 343 patients who drank prior to admission and 32% among 352 patients who did not drink alcohol before admission. Breath alcohol levels were positively associated with AUDIT scores. The sensitivity against a previous or current alcohol-related medical diagnosis was 89%. We concluded that the AUDIT is a satisfactory instrument for alcohol screening in this population.     

Measurements,Instruments, Scales,and Tests: Use of AUDIT for Alcohol Screening among Emergency Room Patients in Thailand

This study evaluated the Alcohol Use Disorders Identification Test (AUDIT) against blood alcohol levels and medical diagnoses. The population under study included 695 current drinkers admitted to emergency rooms of four regional Thailand hospitals. The AUDIT positivity rate was 61% among 343 patients who drank prior to admission and 32% among 352 patients who did not drink alcohol before admission. Breath alcohol levels were positively associated with AUDIT scores. The sensitivity against a previous or current alcohol-related medical diagnosis was 89%. We concluded that the AUDIT is a satisfactory instrument for alcohol screening in this population.     

Confirmatory factor analyses of the alcohol use disorders identification test (AUDIT) among adolescents treated in emergency departments

OBJECTIVE: The Alcohol Use Disorders Identification Test (AUDIT) is a 10-item instrument designed by the World Health Organization to assess problematic drinking. The objective of this study was to conduct confirmatory factor analysis of the AUDIT in a sample of adolescents and young adults who were treated in emergency departments. METHOD: Adolescents and young adults (N= 103, 55 males), ranging in age from 12 to 20.9 years (mean [SD] age = 17.5 [2.1]), completed the AUDIT. Confirmatory factor analyses were conducted using LISREL 8.20 software to test the one-factor, two-factor and three-factor solutions for the AUDIT reported in the literature. RESULTS: Goodness-of-fit indices indicated that a correlated two-factor solution, consisting of a consumption factor and an alcohol-related-problems factor, provides the best fit to the data. The three-factor solution fits the data equally well, but Factor 2 (dependency) and Factor 3 (problems) correlate 1.00. The one-factor solution did not provide a good fit to the data. CONCLUSIONS: Our findings support those of others who have reported that the AUDIT assesses a consumption factor and an alcohol-related problems factor among primary care patients at risk for problematic drinking behavior.     

Is frequency of drinking an indicator of problem drinking? A psychometric analysis of a modified version of the alcohol use disorders identification test in Switzerland.

BACKGROUND: To study the psychometric properties of a modified Alcohol Use Disorders Identification Test in the multilingual context of Switzerland. METHODS: Data were obtained from the most extensive health survey to date in Switzerland, with a response rate of 69%. Seven core items of AUDIT were used. The first two items of AUDIT (frequency of drinking, quantity of drinking) were not used in their original form, but reconstructed from a quantity-frequency instrument (QF) measuring alcohol consumption, and categorized according to the AUDIT. The third AUDIT item (frequency of binge drinking) was similarly not used in its original form, but 8+ drinks instead of 6+ drinks was used. All 10 items of the modified AUDIT were completed by 10321 subjects - 6677 in the German-speaking region and 3644 in the Latin-language (French, Italian) regions. The dimensionality of the modified AUDIT was modelled by confirmatory factor analysis. The contribution of each item to the total modified AUDIT score was investigated by the prevalence of positively screened subjects when items were deleted, and factor loadings of the unidimensional model. RESULTS: In Switzerland the modified AUDIT fitted neither a unidimensional nor the hypothesized tri-dimensional model. Consumption items, especially frequency of drinking, showed almost no correlation with items measuring alcohol-related problems, but the latent constructs 'harmful drinking' and 'alcohol dependence' were highly correlated, indicating a shared underlying factor. Frequency of drinking was the item that most influenced whether an individual screened positively or not. Except for the correlation of frequency and binge drinking, results were almost identical for both linguistic regions. CONCLUSIONS: The current form of the modified AUDIT may have to be changed for screening in Switzerland, as the study raised questions about the suitability of the frequency-of-drinking item as an indicator of a screening device for alcohol-related problems in this country.
