BACKGROUND: Previous studies have shown that elevated, risky levels of alcohol consumption may lead to higher rates of sickness absence. However, no studies have examined the Alcohol Use Disorders Identification Test (AUDIT) or serum carbohydrate-deficient transferrin (CDT) in relation to sickness absence in the workplace. The purpose of this study was to examine the relationship between sick-days, 12 months before screening, and the AUDIT and CDT (CDTect kit). Serum gamma-glutamyltransferase also was used for comparison. METHOD: The study was carried out over 36 months in a large workplace and formed part of an ongoing controlled study. In conjunction with a routine health examination, employees were offered the opportunity to undergo an alcohol screening. Absence data were obtained from the company payroll system, and sickness absence was analyzed by using a three-ordinal level cumulative logistic model on the number of sick-days. Odds ratios (OR) and 95% confidence intervals (CI) are reported. RESULTS: Of the 989 subjects who participated in the study, 193 (19.5%) screened positive in relation to either the AUDIT (>or=8 points) or CDT (<20 units/liter for men, and <27 units/liter for women), or both. Employees who screened positive with the AUDIT had a significantly higher proportion of sick-days (p = 0.047) compared with those who screened negative (OR = 1.4, CI 1.0-1.9). Neither long, continuous periods of sickness absence nor absence on Mondays or Fridays gave a clear indication of individuals who screened positive on the AUDIT or CDT test. CONCLUSION: Our data indicate that individuals with moderately elevated or risky levels of alcohol consumption show an increase in sick-days. Accordingly, workplaces have a good reason for using a more systematic approach to alcohol screening in routine workplace health examinations.  相似文献

BACKGROUND: Moderate consumption of alcohol may reduce mortality from vascular diseases. The beneficial effects of alcohol may partly be mediated by its effects on lipoprotein metabolism. We studied the connection between alcohol consumption and the serum lipid profile from a well-documented national health program study. METHODS AND RESULTS: Carbohydrate-deficient transferrin (CDT) and gamma-glutamyl-transferase (GGT) were used as biochemical markers for alcohol consumption. The laboratory analyses were carried out on 5675 subjects (3097 males and 2578 females). The subjects were divided into quartiles on the basis of CDT or GGT value. The highest CDT quartile and the lowest GGT quartile seemed to be associated with a favorable lipid profile and the lowest CDT quartile and the highest GGT quartile were associated with an unfavorable lipid profile. Serum high density lipoprotein (HDL) cholesterol values were significantly higher and triglycerides lower with increasing serum CDT concentrations for both men and women. Increasing serum GGT was associated with higher serum total cholesterol and higher triglycerides in both men and women and lower HDL cholesterol in men. CONCLUSIONS: CDT and GGT seem to detect different populations of subjects in regard to lipid metabolism. These observations may lead to a better understanding of the effects of alcohol consumption on lipids as well as mechanisms behind favorable and detrimental effects of alcohol on vascular diseases. Condensed abstract: Carbohydrate-deficient transferrin (CDT) and gamma-glutamyl-transferase (GGT) were used as biochemical markers for alcohol consumption. A total of 3097 males and 2578 females were divided into quartiles on the basis of their CDT or GGT values. The highest CDT quartiles had higher HDL and lower triglycerides, whereas the highest GGT quartiles appeared to be associated with higher total cholesterol and triglycerides in both genders and lower HDL in men. CDT and GGT seem to detect different populations of subjects in regard to lipid metabolism. These observations may have important clinical and public health implications.  相似文献

BACKGROUND: Serum levels of total HDL cholesterol (HDL) are reportedly influenced by recent alcohol intake. We examined the correlation between HDL cholesterol and widely used markers of excessive alcohol intake, such as carbohydrate-deficient transferrin (CDT), gamma-glutamyl-transferase (GGT), or mean corpuscular volume of erythrocytes (MCV), of which CDT is thought to be the most specific. METHODS: Several serological markers [i.e., CDT, GGT, aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), MCV, and HDL] were determined in 100 actively drinking male patients with alcohol dependence (DSM-IV) and in 27 non-alcohol-dependent controls, according to routine procedures. Spearman's rank correlation coefficients were calculated. RESULTS: We found a highly significant positive correlation between HDL and CDT (r(s) = 0.55; p < 0.0005) in patients, but not in controls (r(s) = 0.13;p = 0.51). HDL was also positively correlated with GGT, ALAT, ASAT, and MCV only in patients. CONCLUSIONS: HDL cholesterol, as a widely determined parameter, may represent a useful routine marker for recent excessive alcohol intake. High HDL cholesterol levels should alert clinicians to investigate a patient's recent pattern of alcohol consumption.  相似文献

Background: Carbohydrate-deficient transferrin (CDT) and γ-glutamyl transferase (GGT) are used as biomarkers of alcohol misuse. The aim of this study was to evaluate, in terms of sensitivity and specificity, the performance of the new Bio-Rad %CDT TIA kit and GGT assay for identifying alcohol abuse and alcohol dependence (according to the DSM-IV criteria).
Methods: An open multicenter study (30 centers) over 3 months, including patient groups of "abusers,""dependents," and controls, was conducted in France.
Results: In alcohol abuse, the sensitivity of GGT was 0.56, and that of CDT was 0.80; in alcohol dependence, the sensitivity of GGT was 0.86, and that of CDT was 0.91. The specificity of GGT was 0.77, and that of CDT was 0.83. The association of GGT with CDT increased sensitivity for alcohol abuse to 0.90 and for alcohol dependence to 0.99, but it appreciably decreased specificity (0.63).
Conclusions: %CDT is the better screening marker for alcohol abuse and dependence, but GGT is still a useful marker for the detection of alcohol dependence. As an assay method, the second-generation Bio-Rad %CDT immunoassay can be recommended for routine CDT measurement.  相似文献

BACKGROUND: Assessment of high-risk drinking in the general population can be problematic: questionnaire-based instruments may carry the problem of random or systematic recall bias, and the effectiveness of screening of single biomarkers has been shown to be insufficient. In this article, we analyze the alcohol intake/biomarker relationship of carbohydrate-deficient transferrin (CDT), gamma-glutamyltransferase (GGT), and erythrocyte mean corpuscular volume (MCV). Specific aims were (1) screening effectiveness comparison of GGT, CDT, and MCV in terms of sensitivity, specificity, and positive (PPVs) and negative predictive values (NPVs) and the effect of covariates on these measures; (2) the comparison of summary measures for the effectiveness of screening: the receiver characteristic curve (ROC) and the area under the ROC; and (3) to answer the question of which covariates effect which biomarkers and whether accounting for relevant covariates increases the prognostic value of biomarkers to levels that allow for application in the general population. METHODS: In a representative cross-sectional health survey in northeast Germany with data collection from 1997 to 2001, 4310 men and women were asked for their recent alcohol consumption and smoking. Biomarkers were analyzed from blood samples. The effectiveness of screening of CDT, GGT, and MCV for high-risk drinking (men: >60 g/day, women: >40 g/day) was analyzed with PPV and ROC curve analysis. RESULTS: For all three biomarkers, PPVs for high-risk drinking are very low (< 50%). There are some effects of covariates on screening effectiveness and on PPV, and knowledge of these covariates increases screening effectiveness, but no subgroup that had a combination of covariate levels and prevalence of high-risk drinking that led to a PPV > 50% could be found. CONCLUSIONS:: Accounting for covariates in the screening procedure does not lead to a sufficient increase in PPV. Screening effectiveness of laboratory markers CDT, GGT, and MCV is insufficient for their application as screening tools for high-risk alcohol drinking in the general population. This was found using self-reported alcohol consumption as an imperfect gold standard, which is a limitation of the study, although self-reports are the standard instrument in comparable epidemiologic studies.  相似文献

To determine the prevalence of “hazardous drinkers,” 1,064 Mexican inpatients (ages 18–59 years) from nine general hospitals answered an Alcohol Use Disorders Identification Test (AUDIT) questionnaire, previously validated by the World Health Organization. When subjects scored positive, a clinical screening procedure and a serum gamma-glutamyl-trans-peptidase (GGT) test were carried out. An AUDIT score ≥ 8 (hazardous drinking) was found in 23.4% of the sample (43.2% in men vs. 3.6% in women). Patients' answers were positively correlated in 83.3% with those of their next of kin. The clinical screening procedure and serum GGT levels correlated with AUDIT scores ≥ 8 in 55%. Data support the recommendation of routine screening for alcohol consumption in a general hospital population and the usefulness of the AUDIT application as a screening instrument for early phases of hazardous use of alcohol.  相似文献

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.  相似文献

In this pilot study, we compared two brief screening instruments, the T-ACE (Tolerance, Annoyed, Cut down, Eye-opener) and the Alcohol Use Disorders Identification Test (AUDIT), with a clinician interview and structured clinical interview (SCID) to determine if they improved identification of risky drinking in a psychiatry clinic compared to clinician interviews. Sixteen of 50 subjects satisfied DSM-IV criteria for lifetime alcohol abuse or dependence on the SCID, and four, all T-ACE positive, were listed "correctly" in the chart as having an alcohol problem. With an SCID gold standard, risky drinking was identified with sensitivities and specificities of 0.88 and 0.59 for the T-ACE and 0.63 and 0.85 for the AUDIT. Brief screening instruments improved the identification of risky drinking in a psychiatry clinic.  相似文献

Background: The currently available biological markers are limited in sensitivity and specificity for screening of excessive alcohol drinkers. We recently purified and identified 3 potential markers for alcoholism (5.9 and 7.8 kDa peptides and 28 kDa protein) by using surface-enhanced laser desorption/ionization (SELDI-TOF MS) technology. In the present study, we determined the diagnostic values of these novel markers in screening habitual drinkers with moderate alcohol consumption (hereafter habitual drinkers) in the general population as compared with 2 conventional markers: γ -glutamyltransferase (GGT) and carbohydrate-deficient transferrin (CDT).
Methods: Serum samples obtained from a total of 128 Japanese who sought regular medical checkup were analyzed by SELDI-TOF MS.
Results: The relative intensities of the 5.9 and the 28 kDa peak of habitual drinkers were significantly different from those in nondrinkers even in GGT nonresponders. The sensitivity and specificity were the highest in 5.9 kDa. When 5.9, 28 kDa, and GGT were combined, 96.8% of the habitual drinkers were successfully screened with a specificity of 60.9%.
Conclusion: The results of this study clearly indicate that the 5.9 kDa peak is a promising novel biological marker for moderate alcohol consumption.  相似文献

BACKGROUND: Moderate alcohol consumption may reduce the risk of coronary heart disease (CHD), but excessive alcohol consumption is probably harmful to the heart. We analyzed the association of 2 commonly used markers of alcohol consumption-carbohydrate-deficient transferrin (CDT) and gamma-glutamyltransferase (GGT)-and self-reported alcohol consumption with prevalent CHD. METHODS: The study included a random sample of 3666 Finnish men aged 25 to 74 years who participated in a risk factor survey in 1997. The cross-sectional association of CDT, GGT, and self-reported drinking with CHD was analyzed by means of logistic regression models. RESULTS: The CDT level was inversely and GGT level positively associated with CHD risk. The odds ratios (adjusted for age, smoking, total and high-density lipoprotein cholesterol levels, systolic blood pressure, and body mass index) of CHD among men in the fourth quartiles of CDT and GGT, as compared with the first quartiles, were 0.69 and 1.76, respectively. In a composite risk assessment, men with normal CDT levels (< or =20 U/L) and elevated GGT levels (>80 U/L) had nearly 8-fold adjusted risk of CHD as compared with the men with normal GGT levels and elevated CDT levels. Self-reported alcohol consumption had an inverse association with CHD risk, which disappeared after adjustment for the other risk factors. CONCLUSIONS: Levels of CDT and GGT may be indicators of factors behind the curvilinear association between alcohol consumption and CHD risk. The CDT level seems to be related to beneficial biological changes and GGT level with the changes that are detrimental to the cardiovascular system. The inverse association of CDT level with CHD risk will be examined further in a forthcoming prospective study.  相似文献

BACKGROUND: Early identification of alcohol problems in women is important. Differences in patterns of drinking and in biological function between genders, however, may present unique difficulties in biochemical screening. METHODS: Published alcohol-screening studies with female samples and use as biomarkers of carbohydrate-deficient transferrin (CDT), gamma-glutamyltransferase (GGT), and macrocytic volume were reviewed. RESULTS: A wide range of sensitivities and specificities of GGT and CDT have been reported, although, in general, the two markers seem approximately equal in accuracy. As in the case of males, use of them in combination substantially enhances sensitivity and little reduces specificity. Use of macrocytic volume improves the sensitivity of both GGT and CDT as alcohol-screening markers. CONCLUSIONS: GGT and CDT have moderate sensitivity in screening for alcohol problems in women. Use of them in concert offers further advantage.  相似文献

BACKGROUND: The purpose of this study was to compare the sensitivity and specificity of some new and traditional biological markers and indicators of health among Brazilian nondrinkers, drinkers, and alcohol-dependent patients. MATERIAL AND METHODS: We evaluated 130 nondrinkers, 167 drinkers, and 183 alcohol-dependent drinkers from Brazil who participated in the WHO/ISBRA Study on State and Trait Markers of Alcohol Use and Dependence. A standardized WHO/ISBRA Interview Schedule provided background information on the subjects' characteristics including reported health problems and alcohol consumption. Blood samples were analyzed for aspartate aminotransferase (AST), carbohydrate deficient transferrin (CDT), gamma-glutamyltransferase (GGT), blood alcohol levels (BAL), and platelet adenylate cyclase activity (basal levels [AC] and levels after stimulation with Gpp(NH)p, cesium fluoride, and forskolin). RESULTS: The alcohol-dependent drinkers presented higher levels of AST, GGT, AC, CDT, and BAL than the nondrinkers and drinkers, whose levels were similar. Sex differences in the sensitivity of CDT and AC were found. The alcohol-dependent women presented a lower prevalence of abnormal values of CDT and Gpp(NH)p-stimulated AC than the alcohol-dependent men, despite the fact that they presented similar alcohol consumption levels. The alcohol-dependent drinkers presented a higher prevalence of clinical disorders than the nondrinkers and drinkers. The drinkers and alcohol-dependent patients presented significantly higher rates of gastritis than the nondrinkers. CONCLUSIONS: Sex differences in the sensitivity of CDT and AC suggest that these markers are not as sensitive at detecting excessive alcohol use in women as they are in men. If data from this Brazilian sample are compared with those reported for international samples, relevant differences are detected, which suggests that genetic and cultural differences should be considered in the selection of biological markers of heavy alcohol consumption.  相似文献

BACKGROUND: Biological markers like carbohydrate-deficient transferrin (CDT), gamma-glutamyltransferase (GGT), and mean corpuscular volume (MCV) are used widely to screen for alcoholism. Most research has focused on male alcoholics, and there are few studies on female patients. The results are inconsistent; in general, they show lower sensitivities for all markers for women. METHODS: We compared the diagnostic value of CDT, GGT, and MCV in 126 alcohol-dependent patients (91 men, 35 women) who entered an inpatient treatment program. For the receiver operating characteristic (ROC) analyses, we investigated a control group of 112 patients (64 men, 38 women) from the Department of Psychiatry at the University of Tübingen with no diagnosis of substance abuse or substance dependency. RESULTS: Mean levels of CDT and MCV were significantly different in male and female patients. CDT showed higher test results in men (4.4% vs. 2.8%, p < 0.05), whereas mean levels of MCV were higher in women (99.7 fl vs. 96.4 fl,p < 0.01). The sensitivities of CDT and GGT were higher in men than in women (CDT: 76% vs. 54%,p < 0.1; GGT: 68% vs. 43%,p < 0.05), and the sensitivity of MCV was significantly higher in women (71% vs. 41%,p < 0.01). The superiority of MCV in women also was supported by ROC analyses (p < 0.01). The combined use of markers showed satisfactory sensitivity rates of > or = 80% not only in men but also in women. Yet, the specificity rates were partly below the recommended 90% for identifying alcohol abuse; therefore, these markers must be combined with caution. CONCLUSIONS: If combined, the biological markers CDT and GGT are useful diagnostic instruments for both alcohol-dependent men and women. According to our results, the "forgotten" marker MCV is superior in women and is a marker of second choice in men. The combination GGT and MCV is the most cost-effective choice for men and women.  相似文献

Optimal selection of liver transplant candidates and early detection of alcohol relapse after orthotopic liver transplantation (OLT) is necessary to improve long-term outcomes. In this study, urinary ethyl glucuronide (uEtG) was prospectively evaluated as a novel screening tool for alcohol detection in the transplant setting. Overall, 141 liver transplant candidates and recipients, visiting the outpatient clinic for a total of 308 times, were included. At each visit, the alcohol markers, uEtG, ethanol, methanol, and carbohydrate-deficient transferrin (CDT), as well as the state markers, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase (GGT), and mean corpuscular volume (MCV), were determined, then compared to patients' self-reports on alcohol intake. Urinary EtG significantly increased the detection rate of alcohol consumption, compared to the other alcohol markers (P < 0.001). In 93% of patients and at 92.5% of visits with positive alcohol markers, alcohol intake was detected by uEtG and/or CDT. Sensitivity and specificity of uEtG were 89.3% and 98.9% and of CDT were 25% and 98.6%, respectively. Urinary EtG was the best independent predictor of alcohol consumption in univariate and multivariate analysis (positive predictive value: 89.3%; negative predictive value: 98.9%; odds ratio: 761.1; P < 0.001). It showed a superior prediction rate, when compared to established alcohol and state markers, as well as to the combination of CDT with MCV and GGT, assessed by net reclassification improvement (NRI) (NRI: 1.01, P < 0.001; NRI: 1.755, P < 0.001). CONCLUSION: uEtG is a sensitive, specific, and reliable marker for the detection of recent alcohol intake pre- and post-OLT. In combination with CDT, uEtG should be considered as a tool for routine alcohol screening within the transplant setting.  相似文献

Four alcohol screening instruments (the AUDIT, CAGE, MAST, and Svanum's scale) were administered to a sample of 306 undergraduate students at a Midwestern university and were compared with regard to several test characteristics, using the alcohol section of the CIDI-SAM (DSM-IV version) as the criterion measure. The performance of these instruments was evaluated using two subsets of subjects: (1) students who currently met diagnostic criteria for alcohol dependence ( n = 35); and (2) students who met diagnostic criteria for alcohol dependence in the past and/or at present (i.e., lifetime diagnosis; n = 50). The AUDIT performed significantly better than the other three instruments in identifying students who were currently alcohol dependent, providing a moderate degree of clinical utility with this group. The four instruments did not differ significantly in their ability to identify students with a lifetime diagnosis; each measure provided only a modest degree of clinical utility with this group.  相似文献

BACKGROUND: The application of biochemical markers to detect heavy alcohol use in women has shown disappointing results until now. We evaluated carbohydrate-deficient transferrin (CDT) by the CDTect method and gamma-glutamyltransferase (GGT) in a large cohort of alcohol-using perimenopausal women studied primarily for osteoporosis. METHODS: CDT and GGT were measured in 431 women aged 46 to 54 years, who were selected from a large cohort (n = 8503) of pre-, peri-, and postmenopausal women. Their alcohol intake was known from questionnaires and face-to-face interviews. Three groups were constructed for statistical analysis: those drinking on average less than 7 alcoholic drinks per week (n = 103), those drinking 7 to 34 per week (n = 280), and those drinking at least 35 per week (n = 48). RESULTS: The mean values of CDT and GGT of the three groups increased with an increasing alcohol intake, but there was a poor correlation between CDT and GGT in the complete study group (r = 0.3). The specificities of CDT and GGT were comparable, 83% and 78%, respectively. The sensitivities for CDT and GGT were 30% and 50%, respectively. A logistic regression model could assign, overall, 77% of the women correctly in relation to their alcohol intake: 43% of the women drinking at least 35 drinks per week and 92% of the women drinking less than 7 drinks per week. CONCLUSIONS: The test characteristics of both GGT and CDT are not good enough to be used as biochemical markers for detecting heavy alcohol use in women. The use of a logistic regression model offers an advantage, because both numeric values of CDT and GGT are taken into account instead of arbitrary cutoff values.  相似文献

Older drinkers may incur alcohol-related risks at low consumption levels, but commonly used screening measures do not address alcohol's effects among persons with declining health and increased medication use. We compared the newly developed Alcohol-Related Problems Survey (ARPS) to three validated alcohol screens: the Cut down, Annoyed, Guilty, Eye-opener (CAGE), Short-Michigan Alcohol Screening Test (SMAST), and Alcohol-Use Identification Test (AUDIT). The ARPS classifies drinking as non-hazardous, hazardous or harmful. Non-hazardous drinking is defined as consumption with no known risks for adverse physical or psychological health events. Hazardous drinking is consumption with such risks. Harmful drinking results in adverse events. The AUDIT screens for hazardous and harmful drinking; the CAGE and SMAST identify abusive (e.g. failure to fulfill social obligations) and dependent (e.g. having withdrawal symptoms) drinkers. In this study of 574 current drinkers 65 years and older who completed the ARPS and AUDIT in primary care clinics, half were randomly assigned to complete the CAGE and half, the SMAST. Drinkers who screened positive on the CAGE, SMAST or AUDIT were correctly classified by the ARPS as hazardous or harmful drinkers 91, 75, and 100% of the time, respectively. The majority of ARPS-identified hazardous or harmful drinkers did not screen positive on the CAGE, SMAST or AUDIT. These drinkers had medical conditions or used medications that placed them at risk for adverse health events, none of which was addressed in these three screens. In this study, the ARPS identified nearly all drinkers detected by the CAGE, SMAST, and AUDIT and detected hazardous and harmful drinkers not identified by these measures.  相似文献

BACKGROUND: The ability to reliably detect heavy alcohol use is important in both clinical and research populations. The current study evaluates the utility of the newest method of measuring carbohydrate deficient transferrin (CDT) in monitoring the abstinence during a treatment outcome study. METHODS: Blood from 40 alcohol dependent individuals was obtained at baseline and at weeks 4, 8, and 12 of treatment. Differences in percent of baseline GGT and %CDT levels were analyzed in people who remained abstinent throughout treatment (abstainers) and in those who consumed alcohol during treatment (drinkers). RESULTS: There was a significant decrease in the percent of baseline %CDT levels in the subjects who abstained at week 4 and a trend at weeks 8 and 12. Conversely, there were no significant differences in percent of baseline GGT levels between drinkers and abstainers at any time point. CONCLUSIONS: Although small in nature, this study provides preliminary evidence for the use of the relatively new Biorad %CDT assay to monitor drinking status during treatment outcome studies. This study is also consistent with previously reported findings that GGT appears to be less sensitive than %CDT in detecting the consumption of alcohol. A larger trial focusing on sex differences in the utility of % CDT to monitor outcome would be of interest.  相似文献

Eight previous investigations have suggested that conjoint consideration of findings on tests for gamma glutamyl transpeptidase (GGT) and carbohydrate deficient transferrin (CDT) substantially enhances sensitivity of screening for alcohol problems while minimally diminishing specificity. Using results from a large clinical trial, the current study evaluated the two tests singly and in combination as measures of three clinically important treatment outcome criteria: any drinking, at least one day of heavy drinking, and at least three consecutive days of heavy drinking during the past month. When scored by quartile, CDT is slightly better at screening for alcohol problems in males than GGT. However, CDT seems less accurate in females than GGT. Use of the two tests in consort moderately improves the individual test accuracy in predicting drinking status for both genders.  相似文献

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.  相似文献
