The Alcohol Use Disorders Identification Test (AUDIT): a review of recent research

BACKGROUND: Efficient, inexpensive screening for early stage alcohol problems is important in health care settings. The Alcohol Use Disorders Identification Test (AUDIT) has been studied extensively to establish its value in this regard. METHODS: A literature search that used EtOH as a database was conducted to identify studies published on the AUDIT through September 2001. Keywords used for the search were "Alcohol Use Disorders Identification Test" and "AUDIT." All studies reporting psychometric properties of the measure were reviewed with particular attention being given to the period 1996 and later. A small number of additional references were located by noting their citation in other studies reviewed. RESULTS: Although more research is needed on non-English versions to establish their psychometric properties, at least in its English edition, the AUDIT demonstrates sensitivities and specificities comparable, and typically superior, to those of other self-report screening measures. Test-retest reliability and internal consistency are also quite favorable. For males, the AUDIT-C, a shortened version of the AUDIT, appears approximately equal in validity to the full scale. CONCLUSIONS: Recent research continues to support use of the AUDIT as a means of screening for alcohol use disorders in health care settings in the United States.     

Bayes' Theorem to estimate population prevalence from Alcohol Use Disorders Identification Test (AUDIT) scores

Aim   The aim in this methodological paper is to demonstrate, using Bayes' Theorem, an approach to estimating the difference in prevalence of a disorder in two groups whose test scores are obtained, illustrated with data from a college student trial where 12-month outcomes are reported for the Alcohol Use Disorders Identification Test (AUDIT).
Method   Using known population prevalence as a background probability and diagnostic accuracy information for the AUDIT scale, we calculated the post-test probability of alcohol abuse or dependence for study participants. The difference in post-test probability between the study intervention and control groups indicates the effectiveness of the intervention to reduce alcohol use disorder rates.
Findings   In the illustrative analysis, at 12-month follow-up there was a mean AUDIT score difference of 2.2 points between the intervention and control groups: an effect size of unclear policy relevance. Using Bayes' Theorem, the post-test probability mean difference between the two groups was 9% (95% confidence interval 3–14%). Interpreted as a prevalence reduction, this is evaluated more easily by policy makers and clinicians.
Conclusion   Important information on the probable differences in real world prevalence and impact of prevention and treatment programmes can be produced by applying Bayes' Theorem to studies where diagnostic outcome measures are used. However, the usefulness of this approach relies upon good information on the accuracy of such diagnostic measures for target conditions.     

A Review of Research on the Alcohol Use Disorders Identification Test (AUDIT)

Research on the core version of the Alcohol Use Disorders Identification Test (AUDIT) is reviewed. Sensitivities and specificities of the AUDIT for criteria of current hazardous use and, to a slightly lesser extent, lifetime alcohol dependence are high. In general, AUDIT scores are at least moderately related to other self-report alcohol screening tests. Several studies also show them as correlated with biochemical measures of drinking. Results of the AUDIT have also been associated with more distal indicators of problematic drinking. Indices of internal consistency, including Cronbach's α and item-total correlations, are generally in the 0.80's. Future directions for research on the AUDIT are suggested.     

The Alcohol Use Disorders Identification Test (AUDIT) as a screening tool for excessive drinking in primary care: reliability and validity of a French version

BACKGROUND: Excessive drinking is a major problem in Western countries. AUDIT (Alcohol Use Disorders Identification Test) is a 10-item questionnaire developed as a transcultural screening tool to detect excessive alcohol consumption and dependence in primary health care settings. OBJECTIVES: The aim of the study is to validate a French version of the Alcohol Use Disorders Identification Test (AUDIT). METHODS: We conducted a validation cross-sectional study in three French-speaking areas (Paris, Geneva and Lausanne). We examined psychometric properties of AUDIT as its internal consistency, and its capacity to correctly diagnose alcohol abuse or dependence as defined by DSM-IV and to detect hazardous drinking (defined as alcohol intake >30 g pure ethanol per day for men and >20 g of pure ethanol per day for women). We calculated sensitivity, specificity, positive and negative predictive values and Receiver Operator Characteristic curves. Finally, we compared the ability of AUDIT to accurately detect "alcohol abuse/dependence" with that of CAGE and MAST. RESULTS: 1207 patients presenting to outpatient clinics (Switzerland, n = 580) or general practitioners' (France, n = 627) successively completed CAGE, MAST and AUDIT self-administered questionnaires, and were independently interviewed by a trained addiction specialist. AUDIT showed a good capacity to discriminate dependent patients (with AUDIT > or =13 for males, sensitivity 70.1%, specificity 95.2%, PPV 85.7%, NPV 94.7% and for females sensitivity 94.7%, specificity 98.2%, PPV 100%, NPV 99.8%); and hazardous drinkers (with AUDIT > or =7, for males sensitivity 83.5%, specificity 79.9%, PPV 55.0%, NPV 82.7% and with AUDIT > or =6 for females, sensitivity 81.2%, specificity 93.7%, PPV 64.0%, NPV 72.0%). AUDIT gives better results than MAST and CAGE for detecting "Alcohol abuse/dependence" as showed on the comparative ROC curves. CONCLUSIONS: The AUDIT questionnaire remains a good screening instrument for French-speaking primary care.     

Gender differences in the performance of a computerized version of the alcohol use disorders identification test in subcritically injured patients who are admitted to the emergency department

OBJECTIVE: The Alcohol Use Disorder Identification Test (AUDIT) has been recommended as a screening tool to detect patients who are appropriate candidates for brief, preventive alcohol interventions. Lower AUDIT cutoff scores have been proposed for women; however, the appropriate value remains unknown. The primary purpose of this study was to determine the optimal AUDIT cutpoint for detecting alcohol problems in subcritically injured male and female patients who are treated in the emergency department (ED). An additional purpose of the study was to determine whether computerized screening for alcohol problems is feasible in this setting. METHODS: The study was performed in the ED of a large, urban university teaching hospital. During an 8-month period, 1205 male and 722 female injured patients were screened using an interactive computerized lifestyle assessment that included the AUDIT as an embedded component. World Health Organization criteria were used to define alcohol dependence and harmful drinking. World Health Organization criteria for excessive consumption were used to define high-risk drinking. The ability of the AUDIT to classify appropriately male and female patients as having one of these three conditions was the primary outcome measure. RESULTS: Criteria for any alcohol use disorder were present in 17.5% of men and 6.8% of women. The overall accuracy of the AUDIT was good to excellent. At a specificity >0.80, sensitivity was 0.75 for men using a cutoff of 8 points and 0.84 for women using a cutoff of 5 points. Eighty-five percent of patients completed computerized screening without the need for additional help. CONCLUSIONS: Different AUDIT scoring thresholds for men and women are required to achieve comparable sensitivity and specificity when using the AUDIT to screen injured patients in the ED. Computerized AUDIT administration is feasible and may help to overcome time limitations that may compromise screening in this busy clinical environment.     

Brief Intervention for Problem Drinkers in a Chinese Population: A Randomized Controlled Trial in a Hospital Setting

Background:  Alcohol is a legal and accessible substance in Taiwan. As excessive alcohol has been linked to health and social problems, it is necessary to develop a brief, rapid, and low-cost tool to help health care providers deal with persons in Taiwan whose alcohol consumption has become hazardous or harmful to their health.
Methods:  A randomized controlled clinical trial with 6- and 12-month follow-ups was designed. Eighteen medical/surgical units at a medical center in northern Taiwan were randomly assigned to 2 groups: experimental ( n  = 9) and control ( n  = 9). Inpatients on the units were enrolled if they met the following criteria: were older than 18 years, had no severe psychiatric illness, and were not pregnant. The experimental group ( n  = 138) received the intervention, a 15-minute counseling visit in which nurses screened participants using the Alcohol Use Disorders Identification Test (AUDIT), provided a health promotion booklet for adults, and individually discussed the booklet contents with patients based on their drinking level (AUDIT score). The control group ( n  = 137) received no treatment. Patterns of alcohol consumption were determined by AUDIT scores at baseline, 6, and 12 months later.
Results:  Alcohol use disorders identification test scores decreased significantly in both groups at 6 months after the intervention, but did not differ significantly between the 2 groups. However, 12 months after the brief alcohol intervention, experimental subjects' AUDIT scores were significantly better than those of the control group.
Conclusions:  Our brief alcohol intervention provided a 12-month benefit for problem drinkers in Taiwan.     

Concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) and AUDIT zones in defining levels of severity among out-patients with alcohol dependence in the COMBINE study

AIMS: To examine among alcohol-dependent out-patient clients the concurrent validity of the Alcohol Use Disorders Identification Test (AUDIT) total score and 'zones' suggested by the World Health Organization for defining levels of severity of alcohol use problems. DESIGN: Participants were classified into AUDIT zones (AUDIT total score = 8-15, 16-19, 20-40) and compared on measures of demographics, treatment goals, alcohol consumption, alcohol-related consequences, severity of dependence, physiological dependence, tolerance, withdrawal and biomarkers of alcohol use. SETTING: Eleven out-patient academic clinical research centers across the United States. Participants Alcohol dependent individuals (n = 1335) entering out-patient treatment in the Combined Pharmacotherapies and Behavioral Interventions (COMBINE) study. MEASUREMENTS: The AUDIT was administered as part of an initial screening. Baseline measures used for concurrent validation included the Structured Clinical Interview for Diagnostic and Statistical Manual, 4th edition (DSM-IV) Disorders, the Alcohol Dependence Scale, the Drinker Inventory of Consequences, the Obsessive-Compulsive Drinking Scale, the University of Rhode Island Change Assessment, the Thoughts about Abstinence Scale, the Form-90, %carbohydrate-deficient transferrin and gamma-glutamyl transferase. Findings Indicators of severity of dependence and alcohol-related problems increased linearly with total score and differed significantly across AUDIT zones. The highest zone, with scores of 20 and above, was markedly different with respect to severity from the other two zones and members of this group endorsed an abstinence goal more strongly. CONCLUSIONS: The AUDIT total score is a brief measure that appears to provide an index of severity of dependence in a sample of alcohol-dependent individuals seeking out-patient treatment, extending its potential utility beyond its more traditional role as a screening instrument in general populations.     

Alcohol Use Disorders Identification Test (AUDIT): establishment of cut-off scores in a hospitalized Chinese population

BACKGROUND: Alcohol use has become a problem for Taiwanese society. Developing a brief, rapid, and flexible tool to screen an individual's alcohol consumption is important. Many countries use the Alcohol Use Disorders Identification Test (AUDIT) to screen for harmful and dangerous alcohol consumption. The psychometric characteristics of the AUDIT have not been examined in a Chinese population. METHODS: Determination of the cutoff points for the AUDIT Chinese version included three stages: translating the questionnaire, expert review and formal testing on subjects. Participants (N = 112) were recruited from a medical research center of four gastroenterology wards in northern Taiwan. RESULTS: The cutoff point for participants diagnosed as "harmful users" was an AUDIT score of 8. The sensitivity was 0.96, specificity was 0.85, positive predictive value (PPV) was 0.85, negative predictive value (NPV) was 0.96, and area under the receiver-operating characteristic curve (AUROC) was 0.93. The cutoff point for participants diagnosed as "alcohol dependent" was an AUDIT score of 11. The sensitivity was 0.94, specificity was 0.63, PPV was 0.31, NPV was 0.98, and AUROC was 0.84. Furthermore, males had significantly higher AUDIT and AUDIT-C scores. Males were also significantly more likely than females to be diagnosed as harmful users or alcohol dependents. CONCLUSIONS: The Chinese version of the AUDIT gave the same cutoff point for harmful alcohol use by Taiwanese individuals as that set by the World Health Organization. This finding shows that this cutoff point is generally appropriate in screening for problem alcohol consumption. Moreover, the cutoff AUDIT score of 11 for alcohol dependence provides a reference for screening in Taiwanese clinics.     

Screening Trauma Patients for Alcoholism According to NLAAA Guidelines with Alcohol Use Disorders Identification Test Questions

Drinking pattern criteria (drinking frequency and number of drinks per occasion) issued by the National Institute on Alcohol and Abuse and Alcoholism (NIAAA) to screen primary practice patients for alcohol problems were evaluated in 1216 injured patients treated in a regional trauma center. Vehicular crash victims predominated (50.2%, of whom 64.5% were drivers), followed by victims of violence (31.2%) and nonviolent-injury victims (18.5%). Alcohol Use Disorders Identification Test (AUDIT) questions #1 (drinking frequency) and #2 (drinks/day) were used to assess the patients for current alcohol dependence (CAD). AUDIT responses roughly approximating NIAAA guidelines (high threshold: drinks ≥ 4 times/week, ≥ 5 drinks/day) and those indicating less drinking (low threshold: drinks ≥ 2-3 times/week, ≥3 drinks/day) were chosen. Comparisons were made relative to sensitivity and specificity of responses in detecting CAD. When low threshold responses were used for either question, sensitivity to detect CAD increased overall (#1 from 0.53 to 0.80, #2 from 0.62 to 0.88) as well as among the subgroups of patients, whereas specificity remained high or at acceptable levels overall (#1 from 0.95 to 0.82, #2 from 0.92 to 0.71) and among the subgroups of patients. Study findings suggest that, among injured drivers and other groups of trauma center patients, lesser amounts of drinking should be used as screening criteria for CAD than are used for the general population.     

The alcohol use disorders identification test: an update of research findings

BACKGROUND: The Alcohol Use Disorders Identification Test (AUDIT) has been extensively researched to determine its capability to accurately and practically screen for alcohol problems. METHODS: During the 5 years since our previous review of the literature, a large number of additional studies have been published on the AUDIT, abbreviated versions of it, its psychometric properties, and the applicability of the AUDIT for a diverse array of populations. The current article summarizes new findings and integrates them with results of previous research. It also suggests some issues that we believe are particularly in need of further study. RESULTS: A growing body of research evidence supports the criterion validity of English version of the AUDIT as a screen for alcohol dependence as well as for less severe alcohol problems. Nevertheless, the cut-points for effective detection of hazardous drinking as well as identification of alcohol dependence or harmful use in women need to be lowered from the originally recommended value of 8 points. The AUDIT-C, the most popular short version of the AUDIT consisting solely of its 3 consumption items, is approximately equal in accuracy to the full AUDIT. Psychometric properties of the AUDIT, such as test-retest reliability and internal consistency, are quite favorable. Continued research is urged to establish the psychometric properties of non-English versions of the AUDIT, use of the AUDIT with adolescents and with older adults, and selective inclusion of alcohol biomarkers with the AUDIT in some instances. CONCLUSIONS: Research continues to support use of the AUDIT as a means of screening for the spectrum of alcohol use disorders in various settings and with diverse populations.     

Validity of the obsessive compulsive drinking scale in a heavy drinking population

Background:  The Obsessive Compulsive Drinking Scale [OCDS; Anton et al., Alcohol Clin Exp Res 19 (1995), 92 ] is the most widely used measure of alcohol craving. There are no studies which comprehensively investigate the construct and concurrent validity of the OCDS in a severe alcohol dependent population.
Methods:  Three hundred and seventy alcohol-dependent patients were referred to a hospital-based alcohol treatment program. All participants completed the OCDS, the Alcohol Use Disorders Identification Test [AUDIT; Saunders et al., Addiction 88 (1993), 791 ] and provided demographic and alcohol consumption data.
Results:  The sample was randomly split into 2. Exploratory factor analysis and confirmatory factor analysis were conducted on these subsamples. Both analyses identified a 4-factor solution (compulsions, interference, obsessions and resisting obsessions). All factors showed sound internal consistency. Neither the factor scores nor the total OCDS score was related to baseline alcohol problems (AUDIT) or consumption.
Conclusions:  There was some support for the construct validity of the OCDS in this clinical group. Concurrent validity of the scale was not supported by these cross-sectional data. Future research should examine the predictive utility of the OCDS over time.     

Cost-Effectiveness of Screening for Unhealthy Alcohol Use with %Carbohydrate Deficient Transferrin: Results From a Literature-Based Decision Analytic Computer Model

Background:  The %carbohydrate deficient transferrin (%CDT) test offers objective evidence of unhealthy alcohol use but its cost-effectiveness in primary care conditions is unknown.
Methods:  Using a decision tree and Markov model, we performed a literature-based cost-effectiveness analysis of 4 strategies for detecting unhealthy alcohol use in adult primary care patients: (i) Questionnaire Only, using a validated 3-item alcohol questionnaire; (ii) %CDT Only; (iii) Questionnaire followed by %CDT (Questionnaire-%CDT) if the questionnaire is negative; and (iv) No Screening. For those patients screening positive, clinicians performed more detailed assessment to characterize unhealthy use and determine therapy. We estimated costs using Medicare reimbursement and the Medical Expenditure Panel Survey. We determined sensitivity, specificity, prevalence of disease, and mortality from the medical literature. In the base case, we calculated the incremental cost-effectiveness ratio (ICER) in 2006 dollars per quality-adjusted life year ($/QALY) for a 50-year-old cohort.
Results:  In the base case, the ICER for the Questionnaire-%CDT strategy was $15,500/QALY compared with the Questionnaire Only strategy. Other strategies were dominated. When the prevalence of unhealthy alcohol use exceeded 15% and screening age was <60 years, the Questionnaire-%CDT strategy costs less than $50,000/QALY compared to the Questionnaire Only strategy.
Conclusions:  Adding %CDT to questionnaire-based screening for unhealthy alcohol use was cost-effective in our literature-based decision analytic model set in typical primary care conditions. Screening with %CDT should be considered for adults up to the age of 60 when the prevalence of unhealthy alcohol use is 15% or more and screening questionnaires are negative.     

The Alcohol Use Disorders Identification Test (AUDIT) and carbohydrate-deficient transferrin (CDT) in a routine workplace health examination

BACKGROUND: Only a few studies on workplaces have examined the Alcohol Use Disorders Identification Test (AUDIT) or carbohydrate-deficient transferrin (CDT) as screening instruments for the early identification of elevated and risky levels of alcohol consumption. The purpose of this study was to compare the performances of AUDIT, CDT, and gamma-glutamyltransferase (GGT) in a routine health examination (alcohol screening) in the workplace. METHODS: The study, carried out over 16 months in a large workplace in the transport sector, was part of an on-going controlled study. Employees who came to the company health service for a routine health examination were offered the opportunity to undergo an alcohol screening and check their alcohol habits. RESULTS: Of the 570 subjects who participated, 105 (18.4%) screened positive according to AUDIT, CDT, or both. Only 7.6% of the persons who screened positive did so according to both instruments. If GGT had been included as a screening instrument, the proportion of positive results would have increased to 22.0%. If we had only used AUDIT in the screening process, the proportion of positives would have fallen by nearly half. CONCLUSIONS: The present findings suggest that AUDIT and CDT are complementary instruments for alcohol screening in a routine workplace health examination, and each has value for identifying a different segment of the risky drinking population.     

Reactivity to alcohol assessment measures: an experimental test

Aims   Previous research has suggested that alcohol screening and assessment may affect drinking.
Design   This study was a randomized test of reactivity to alcohol assessment questionnaires among a group of heavy drinking college students.
Setting and participants   A total of 147 university students completed a screening questionnaire and were randomized to either immediate assessment or delayed assessment. The immediate assessment group completed a set of drinking questionnaires at baseline, 3, 6 and 12 months, while the delayed assessment group completed questionnaires only at 12 months.
Measurements   Primary outcomes included overall volume of drinking, risky drinking and use of risk reduction behaviors.
Findings   We found a significant effect of assessment on measures of risky drinking and risk reduction behaviors, but not on overall volume of drinking. Specifically, at 12 months, participants who had previously completed drinking assessments had a lower peak blood alcohol concentration (BAC) ( d  = −0.373), were more likely to report a low score on the Alcohol Use Disorders Identification Test (AUDIT; odds ratio = 2.55) and tended to use more strategies to moderate their alcohol consumption ( d  = 0.352). Risk reduction behaviors that were affected tended to be those that limited alcohol consumption, rather than those that minimized consequences.
Conclusions   These results may have implications for the development of brief interventions.     

Validation of the Alcohol, Smoking And Substance Involvement Screening Test (ASSIST)

AIM: The concurrent, construct and discriminative validity of the World Health Organization's Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) were examined in a multi-site international study. PARTICIPANTS: One thousand and 47 participants, recruited from drug treatment (n = 350) and primary health care (PHC) settings (n = 697), were administered a battery of instruments. MEASUREMENTS: Measures included the ASSIST; the Addiction Severity Index-Lite (ASI-Lite); the Severity of Dependence Scale (SDS); the MINI International Neuropsychiatric Interview (MINI-Plus); the Rating of Injection Site Condition (RISC); the Drug Abuse Screening Test (DAST); the Alcohol Use Disorders Identification Test (AUDIT); the Revised Fagerstrom Tolerance Questionnaire (RTQ); and the Maudsley Addiction Profile (MAP). FINDINGS: Concurrent validity was demonstrated by significant correlations between ASSIST scores and scores from the ASI-Lite (r = 0.76-0.88), SDS (r = 0.59), AUDIT (r = 0.82) and RTQ (r = 0.78); and significantly greater ASSIST scores for those with MINI-Plus diagnoses of abuse or dependence (P < 0.001). Construct validity was established by significant correlations between ASSIST scores and measures of risk factors for the development of drug and alcohol problems (r = 0.48-0.76). Discriminative validity was established by the capacity of the ASSIST to discriminate between substance use, abuse and dependence. Receiver operating characteristic (ROC) analysis was used to establish cut-off scores with suitable specificities (50-96%) and sensitivities (54-97%) for most substances. CONCLUSIONS: The findings demonstrated that the ASSIST is a valid screening test for identifying psychoactive substance use in individuals who use a number of substances and have varying degrees of substance use.     

Alcohol use disorders among emergency department-treated older adolescents: a new brief screen (RUFT-Cut) using the AUDIT, CAGE, CRAFFT, and RAPS-QF

BACKGROUND: Early identification of alcohol use disorders (AUD) among emergency department (ED)-treated patients is important for facilitating intervention and further evaluation outside EDs. A number of brief screening instruments have been developed for identifying patients with AUD, but it is not clear whether they are practical and perform well with older adolescents in an ED setting. This study contrasted four brief screening instruments for detecting DSM-IV-defined AUD and tested a newly developed brief screen for use among ED-treated older adolescents. METHODS: The Alcohol Use Disorders Identification Test (AUDIT), the CAGE, the CRAFFT, and a modified RAPS-QF were given to 93 alcohol-using older adolescents (55% men; aged 18-20 years) in an ED. Receiver operator characteristic analyses were used to evaluate the performance of brief screens against the criterion of a lifetime DSM-IV alcohol abuse or dependence diagnosis. RESULTS: Of existing instruments, the AUDIT had the best overall performance in identifying AUD (sensitivity, 82%; specificity, 78%). A new, shorter screening instrument composed of two AUDIT items, two CRAFFT items, and one CAGE item (RUFT-Cut) performed as well as the AUDIT (sensitivity, 82%; specificity, 78%). CONCLUSIONS: Among existing alcohol screening instruments, the AUDIT performed best for identifying ED-treated older adolescents with alcohol use disorders. The RUFT-Cut is a brief screening instrument for AUD that shows promise for identifying ED-treated older adolescents who are in need of intervention or further evaluation. Future research should focus on use of the RUFT-Cut in other settings with larger, more diverse samples of adolescents.     

Two brief alcohol-screening tests From the Alcohol Use Disorders Identification Test (AUDIT): validation in a female Veterans Affairs patient population

BACKGROUND: Primary care physicians need a brief alcohol questionnaire that identifies hazardous drinking and alcohol use disorders. The Alcohol Use Disorders Identification Test (AUDIT) questions 1 through 3 (AUDIT-C), and AUDIT question 3 alone are effective alcohol-screening tests in male Veterans Affairs (VA) patients, but have not been validated in women. METHODS: Female VA patients (n = 393) completed self-administered questionnaires, including the 10-item AUDIT and a previously proposed modification to AUDIT question 3 with a sex-specific threshold for binge drinking (>/=4 drinks/occasion), and in-person interviews with the Alcohol Use Disorder and Associated Disabilities Interview Schedule. The AUDIT-C, AUDIT question 3 alone, and the 10-item AUDIT were each evaluated with and without the sex-specific binge question and compared with past-year hazardous drinking (>7 drinks/week or >/=4 drinks/occasion) and/or active Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition alcohol abuse or dependence, based on interviews. RESULTS: Eighty-nine women (22.6%) met interview criteria for past-year hazardous drinking and/or active alcohol abuse or dependence. Standard and sex-specific AUDIT-Cs were sensitive (0.81 and 0.84, respectively) and specific (0.86 and 0.85, respectively). Their areas under the receiver operating characteristic curves were equivalent (0.91, and 0.92, respectively) and slightly higher than for the standard 10-item AUDIT (0.87). A single, sex-specific question about binge drinking (modified AUDIT question 3) had a sensitivity of 0.69 and specificity of 0.94, whereas the standard AUDIT question 3 was specific (0.96) but relatively insensitive (0.45). CONCLUSIONS: The standard and sex-specific AUDIT-Cs are effective screening tests for past-year hazardous drinking and/or active alcohol abuse or dependence in female patients in a VA study.     

Prevalence of alcohol use disorders and associated factors: a population-based study using AUDIT in southern Brazil

Aims   To assess the prevalence of potential alcohol use disorders and associated factors using the Alcohol Use Disorders Identification Test (AUDIT).
Design   Cross-sectional study.
Setting   A town in southern Brazil.
Participants   A representative sample of 1260 people aged 15 and over.
Measurements   Demographic, socioeconomic, smoking habit and mental health data were collected. Logistic regression was used in the multivariate analysis, and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.
Findings   Overall prevalence of alcohol use disorder was 7.9%, with 14.5% prevalence among men and 2.4% among women. The risk of alcohol misuse increased across social class ( P linear trend = 0.03) and compared with the highest classes (A and B), groups C through E had ORs of 1.48, 1.51 and 2.36, respectively. Males had an OR of 6.89 (CI 3.61–13.16) compared with women. A linear trend was found ( P  = 0.001) between smoking categories, and smokers (OR 3.27; CI 1.91–5.58) and ex-smokers (OR 1.30; CI 0.56–2.98) were at higher risk than non-smokers. Those with minor psychiatric disorders had a 2.48 OR (CI 1.35–4.56) of presenting a positive test.
Conclusions   The AUDIT detected a high prevalence of potential alcohol use disorders in the population sampled. Those identified are potential targets for preventive measures implemented through health policies.     

Oral and Dental Health in Alcohol Misusing Patients

Dental and oral health and their relationship to nutritional status among a group of alcohol misusers ( n = 107) from south London is reported. The Alcohol Use Disorders Identification Test (AUDIT) questionnaire was validated as an accurate and reliable screening questionnaire for use in alcohol misuse detection by a dentist. Half of the study population consumed >200 units of alcohol/week, and 80% were heavy smokers. A high incidence of tooth wear and trauma to the dentition was recorded. Eight subjects had oral mucosal lesions, including two previously treated carcinomas. The dental health in alcoholics overall was not compromised, but nutritional impairment (body mass index and reduced midarm muscle circumference) was associated with periodontal lesions. Oral mucosal health of alcoholics is of concern, particularly in heavy smokers. The interrelationships between dental-oral health and alcohol-tobacco usage have implications for preventative counseling in this patient group.     

Validity of the alcohol use disorders identification test in college students

BACKGROUND: High-risk alcohol use among college students is associated with accidents, partner violence, unwanted sexual encounters, tobacco use, and performance issues. The identification and treatment of high-risk drinking students is a priority for many college campuses and college health centers. The goal of this study was to test the psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) in college students. METHODS: A convenience sample of students coming into a college health clinic was asked to complete the 10-question AUDIT and then participate in a research interview. The interview focused on assessing students for alcohol abuse and dependence by using the Composite International Diagnostic Interview Substance Abuse Module and timeline follow-back procedures to assess a 28-day drinking history. RESULTS: A total of 302 students met the eligibility criteria and agreed to participate in the study. The sample consisted of 185 females (61%) and 117 males (39%), with a mean age of 20.3 years. Forty students were abstinent, 88 were high-risk drinkers, and 103 met criteria for a 12-month history of dependence. Receiver operator curves demonstrated that the AUDIT had the highest area under the cure for detecting high-risk alcohol use (0.872) and the lowest for identifying persons with a lifetime history of alcohol abuse or dependence (0.775). An AUDIT cutoff score of 6 or greater demonstrated a sensitivity of 91.0% and a specificity of 60.0% in the detection of high-risk drinkers. CONCLUSIONS: The AUDIT has reasonable psychometric properties in sample of college students using student health services. This study supports the use of the AUDIT in this population.
