A Fetal Alcohol Syndrome Screening Tool 总被引:2,自引:0,他引:2
Susan J. Astley Sterling K. Clarren 《Alcoholism, clinical and experimental research》1995,19(6):1565-1571
The purpose of this study was to derive a multivariate, quantitative case definition of the fetal alcohol syndrome (FAS) facial phenotype from a dysmorphologist-derived gold standard and use it to develop an effective screening tool for identification of children at risk for FAS. The facial and physical features of a racially mixed group of children (0.2–10.0 years of age), evaluated by a single dysmorphologist in the University of Washington FAS Clinic, were used to determine which feature or set of features best differentiated between children with and without a diagnosis of FAS. The study population was divided into two groups balanced on gender, age at examination, race, diagnosis, and date of examination. Group 1 was used to identify the most differentiating feature(s), and group 2 was used to validate the differentiating capability of the feature(s). Group 1 included 97 children (20 with FAS and 77 without FAS). Group 2 included 97 children (19 with FAS and 78 without FAS). Discriminant analysis identified smooth philtrum, thin upper lip, and short palpebral fissures as the cluster of features that best differentiated children with and without FAS based on the discriminant function [D = 1.7953086 + 0.8116083 (thin upper lip) + 2.6411562 (smooth philtrum) - 3.4073780 (% predicted right palpebral fissure length)]. Patients with a D-score ± 1.5 were classified as at-risk for FAS (screen positive). Using this cut-off value for the D-score, children in group 1 were classified with 100% sensitivity (20 of 20 true positives) and 90.0% specificity (70 of 77 true negatives). The children in group 2 were classified with 100% sensitivity (19 of 19 true positives) and 87.3% specificity (68 of 78 true negatives). Across all 194 patients, sensitivity was 100% [95% confidence interval (97–100)] and specificity was 89% [95% confidence interval (85 to 93)]. Seventy-one percent (n= 12) of the 17 false-positives had a true classification of possible fetal alcohol effects. Sensitivity and specificity were unaffected by race, gender, and age through 10 years. This screening tool is effective at differentiating children with and without FAS as diagnosed by a single dysmorphologist (S.K.C.) at the University of Washington FAS Clinic. Assessment of diagnostic interrater agreement between trained dysmorphologists and testing in other clinic populations will be needed to assess the tool's external validity. 相似文献

Background: Alcohol expectancies have been linked to drinking behavior in college students, and vary according to a number of factors, including projected dose of alcohol. Research using Multidimensional Scaling (MDS) suggests that drinking may be influenced by activation of differing expectancy dimensions in memory, yet studies have not examined expectancy activation according to projected alcohol doses.
Methods: The present study used Individual Differences Scaling (INDSCAL) to map expectancy networks of college students ( n = 334) who imagined varied drinking at high and low alcohol doses. Expectancy activation was modeled by dose, as well as by gender and by drinking patterns (typical quantity, blood alcohol content, heavy episodic drinking, and alcohol consequences). Expectancies were organized along positive–negative and arousal–sedation dimensions. Anticipation of a high dose of alcohol was associated with greater emphasis on the arousal–sedation dimension, whereas anticipation of a lower dose was associated with greater emphasis on the positive–negative dimension.
Results: Across heavy, medium, and light drinkers, expectancy dimensions were most distinguishable at higher doses; activation patterns were more similar across drinking groups at lighter doses. Modest evidence for the influence of gender on activation patterns was observed. Findings were consistent across alcohol involvement indices.
Conclusions: These data suggest that both dimensionality and context should be considered in the refinement of interventions designed to alter expectancies in order to decrease hazardous drinking. 相似文献

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. 相似文献

Background: Several variations on the CAGE alcohol screening questionnaire have been recommended. This report evaluates modifications and additions to the CAGE. Methods: Alcohol screening questionnaires were evaluated in male VA general medicine patients (n= 227; mean age, 65.8). Mailed questionnaires included two scoring options for the CAGE (standard and last-year time frames), questions about quantity and frequency of drinking, two questions about episodic heavy drinking, and the question “Have you ever had a drinking problem?” Main analyses compared alcohol screening questions, at various cut-points, to a gold standard of hazardous drinking during the past year (≥14 drinks/week or ≥5 drinks on an occasion) and/or DSM-III-R alcohol abuse or dependence, based on standardized interviews. Results: The CAGE questionnaire with a past-year time frame was much less sensitive (0.57 vs. 0.77) but more specific (0.82 vs. 0.59) than the standard CAGE for detecting hazardous drinking during the past year and/or DSM-III-R alcohol abuse or dependence. An eight-item questionnaire that included the standard CAGE was most sensitive (0.92) but had low specificity (0.50). A single question about the frequency of drinking ≥6 drinks on an occasion, included in the eight-item questionnaire, was both relatively sensitive (0.77) and specific (0.83). Conclusion: The CAGE questionnaire with a past-year time frame was an insensitive alcohol-screening test. An eight-item augmented version of the standard CAGE was the most sensitive. A question about the frequency of drinking ≥6 drinks on an occasion performed better than the standard CAGE, which made it the optimal brief screening test for at-risk drinking. 相似文献

Comparison of Screening Instruments for Alcohol Problems Between Black and White Emergency Room Patients from Two Regions of the Country 总被引:5,自引:1,他引:4

A number of brief screening instruments to identify alcohol dependence exist, but the validity of these instruments across ethnic groups or regions of the country is not well established. The sensitivity and specificity of a number of standard screening instruments (CAGE, brief MAST, AUDIT, TWEAK, and RAPS), as well as other measures (History of Trauma Scale, breathalyzer reading, self-reported drinking before the event, and consuming five or more drinks at a sitting at least monthly) are compared against ICD-10 and DSM-IV criteria for alcohol dependence between probability samples of Black and White emergency room patients in Santa Clara County, CA (n= 716) and in Jackson, MS (n= 1330). Variability in the sensitivity of screening instruments among current drinkers was found to be greater between samples for both Blacks and Whites, than for Blacks compared with Whites within the same sample. The AUDIT, TWEAK, and RAPS seemed to perform well by gender and injury status for both Blacks and Whites in the two samples, and no significant differences were found in the performance of these instruments across sample sites. To evaluate the influence of regional differences in alcohol dependence on differences found in the performance of screening instruments, using logistic regression with the simultaneous entry of demographic variables (age, gender, ethnicity, injury status, and site) and drinking variables (breathalyzer reading, serf-reported drinking before the event, and drinking five or more drinks at a sitting at least monthly) to predict alcohol dependence in a merged sample of these patients (Jackson vs. Santa Clara) site was not found to be significant Data suggest that, whereas region of the country may not be important in predicting alcohol dependence in emergency room populations, regional differences in the performance of screening instruments for alcohol dependence may exist, even when ethnicity is taken into account Given distinct regional differences in drinking patterns and problems in the U.S., further research on commonly used screening instruments is needed to determine those screeners most efficient for identifying problem drinking. 相似文献

BACKGROUND: This study attempted to (1) determine the prevalence of alcohol problems in college freshmen, (2) assess the performance of both the CAGE and the Alcohol Use Disorders Identification Test (AUDIT) questionnaires in this population, and (3) assess the possibility of improving the CAGE and/or AUDIT. METHODS: A sample of 3564 consecutive college freshmen, with a mean age of 18 years, at the Catholic University of Leuven, (Belgium) completed, during a cross-sectional study, a questionnaire assessing drinking behavior and identifying students at risk as defined by DSM-IV criteria. The questionnaire also included the CAGE questionnaire and the AUDIT. Calculations of sensitivity, specificity, negative predictive value, positive predictive value, likelihood ratios, and receiver operating characteristic curves for different scores of the CAGE and the AUDIT were performed, using DSM-IV criteria as the reference standard. RESULTS: The area under the receiver operating characteristic curve of the CAGE and the AUDIT was 0.76 and 0.85, respectively. The cutoff score of 1 for the CAGE was associated with a sensitivity of 42%, a specificity of 87%, a positive predictive value of 36%, and a negative predictive value of 90%. A score of 6 or more for the AUDIT gave a sensitivity of 80%, a specificity of 78%, a positive predictive value of 37%, and a negative predictive value of 77%. These results were related with a prevalence of 14.1% of alcohol problems. Replacing one question of the CAGE by "often driving under the influence" resulted in the CUGE (acronym for "cut down, under influence, guilty feelings, and eye opener"), with an area under the curve of 0.96, a positive likelihood ratio of 8.7, and a negative likelihood ratio of 0.04. CONCLUSIONS: Prevalence of alcohol problems in college students is confirmed to be high. When screening for alcohol problems in a college freshmen population, one question seems extremely important. The newly constructed CUGE questionnaire may improve screening efforts in students, compared with existing questionnaires. 相似文献

The performance of standard screening instruments and alternate measures against ICD-10 (International Classification of Diseases, 10th revision) and DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th revision) criteria for alcohol dependence and separately for harmful drinking/abuse were compared between probability samples of 1511 emergency room (ER) patients from three hospitals in Pachuca, Mexico, and 586 Mexican-American ER patients in Santa Clara County, California. Sensitivity was highest for the Alcohol Use Disorders Identification Test (AUDIT), TWEAK, and Rapid Alcohol Problems Screen (RAPS) for alcohol dependence; sensitivity was highest for holding five or more drinks for harmful drinking/abuse in both samples. All instruments performed better for alcohol dependence than for abuse/harmful drinking. Arrests for drinking and driving performed better in Santa Clara than in Pachuca, while a positive Breathalyzer reading and reporting drinking prior to the event performed better in Pachuca; both were significantly more sensitive among the injured compared to the noninjured in Pachuca. The data suggest that instrument performance may be similar between those in Pachuca and those in the low acculturation group in Santa Clara, relative to those scoring higher on acculturation. While standard screening instruments appear to work reasonably well in both samples for alcohol dependence, variation across gender, injury, and acculturation subgroups suggests attention should be given to choosing the “best” instrument. 相似文献

BACKGROUND: The purpose of this study was to compare the performance (sensitivity and specificity) of two brief screening instruments, CAGE and the Rapid Alcohol Problems Screen 4 (RAPS4), against ICD-10 and DSM-IV criteria for alcohol dependence and abuse in a representative sample of the U.S. adult household population by gender, ethnicity, and service utilization (emergency room and primary care) in the last year. METHODS: Data are from the Alcohol Research Group's 2000 National Alcohol Survey (n = 7612), which is a computer-assisted telephone interview survey of the U.S. general population 18 and over in all 50 U.S. states and the District of Columbia. RESULTS: Sensitivity of the RAPS4 (0.86) was better than the CAGE (0.67) given similar specificity (0.95 vs. 0.98) and outperformed the CAGE for alcohol dependence across all gender, ethnic, and service utilization groups, except among blacks and Hispanics. The RAPS4 also performed equally well for females and males (0.88 vs. 0.85), whereas sensitivity of the CAGE was lower for females. Although sensitivity of the RAPS4 was better than the CAGE for alcohol abuse, sensitivity was low for both (0.56 and 0.36, respectively). When quantity-frequency (QF) questions (drinking five or more drinks on at least one occasion during the last year and drinking as often as once a month during the last year) were added to the RAPS4, the RAPS4-QF performed significantly better for alcohol abuse and outperformed the CAGE at a cut point of one across all gender, ethnic, and service utilization groups. The RAPS4-QF appeared to be most sensitive for alcohol abuse among both males and females reporting emergency room use (0.90). CONCLUSIONS: The data suggest that the RAPS4 outperforms the CAGE in this general population sample. The addition of a QF question to the RAPS4 improves performance in relation to sensitivity for alcohol abuse, and the RAPS4 and RAPS4-QF may be the instruments of choice in brief screening for alcohol use disorders. Additional research is needed to further explore these issues. 相似文献

Early identification of and intervention for fetal alcohol spectrum disorder (FASD) has been shown to optimize outcomes for affected individuals. Detecting biomarkers of prenatal alcohol exposure (PAE) in neonates may assist in the identification of children at risk of FASD enabling targeted early interventions. Despite these potential benefits, complicated ethical issues arise in screening for biomarkers of PAE and these must be addressed prior to the implementation of screening programs. Here, we identify and comment, based on a North American perspective, on concerns raised in the current ethical, social, and legal literature related to meconium screening for PAE. Major ethical concerns revolve around the targeting of populations for PAE screening, consent and respect for persons, stigma and participation rates, the cost—benefit analysis of a screening program, consequences of false‐positive and false‐negative test results, confidentiality and appropriate follow‐up to positive screen results, and the use of screen results for criminal prosecution. We identify gaps in the literature on screening for PAE, most notably related to a lack of stakeholder perspectives (e.g., parents, healthcare providers) about screening and the ethical challenges it presents. 相似文献

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. 相似文献

Contrasting Self-Report Screens for Alcohol Problems: A Review 总被引:6,自引:0,他引:6

Current trends in conceptions of alcohol problems and provision of health care put increased emphasis on identifying individuals whose alcohol use and problems cover a range of severity. The purpose of this study is to begin to provide information on the relative utility of self-report measures designed to identify (screen for) individuals with alcohol problems. To achieve this goal, the empirical literature on contrasts of self-report screening measures was reviewed, and 13 relevant studies across diverse settings and subject populations were identified. The review showed that the CAGE, the Michigan Alcoholism Screening Test (MAST), and the short MAST (sMAST) have been the most widely studied self-report instruments to screen for alcohol problems. Direct comparisons show the MAST to be more sensitive than the CAGE, but with elderly patients the CAGE may perform better than the MAST. Furthermore, available data suggest that the CAGE and the sMAST perform comparably. Finally, the CAGE, MAST, and sMAST all perform best when predicting criteria most similar to those the instruments were designed to reflect. The study concludes with a discussion of priorities for research on screening instruments. 相似文献

Alcohol exposure during pregnancy can cause adverse effects to the fetus, because it interferes with fetal development, leading to later physical and mental impairment. The most common clinical tool to determine fetal alcohol exposure is maternal self‐reporting. However, a more objective and useful method is based on the use of biomarkers in biological specimens alone or in combination with maternal self‐reporting. This review reports on clinically relevant biomarkers for detection of prenatal alcohol exposure (PAE). A systematic search was performed to ensure a proper overview in existing literature. Studies were selected to give an overview on clinically relevant neonatal and maternal biomarkers. The direct biomarkers fatty acid ethyl esters (FAEEs), ethyl glucuronide (EtG), ethyl sulfate, and phosphatidylethanol (PEth) were found to be the most appropriate biomarkers in relation to detection of PAE. To review each biomarker in a clinical context, we have compared the advantages and disadvantages of each biomarker, in relation to its window of detectability, ease of collection, and the ease and cost of analysis of each biomarker. The biomarkers PEth, FAEEs, and EtG were found to be applicable for detection of even low levels of alcohol exposure. Meconium is an accessible matrix for determination of FAEEs and EtG, and blood an accessible matrix for determination of PEth. 相似文献

Alcohol use disorders (AUDs) are complex traits, meaning that variations in many genes contribute to the risk, as does the environment. Although the total genetic contribution to risk is substantial, most individual variations make only very small contributions. By far the strongest contributors are functional variations in 2 genes involved in alcohol (ethanol [EtOH]) metabolism. A functional variant in alcohol dehydrogenase 1B (ADH1B) is protective in people of European and Asian descent, and a different functional variant in the same gene is protective in those of African descent. A strongly protective variant in aldehyde dehydrogenase 2 (ALDH2) is essentially only found in Asians. This highlights the need to study a wide range of populations. The likely mechanism of protection against heavy drinking and AUDs in both cases is alteration in the rate of metabolism of EtOH that at least transiently elevates acetaldehyde. Other ADH and ALDH variants, including functional variations in ADH1C, have also been implicated in affecting drinking behavior and risk for alcoholism. The pattern of linkage disequilibrium in the ADH region and the differences among populations complicate analyses, particularly of regulatory variants. This critical review focuses upon the ADH and ALDH genes as they affect AUDs. 相似文献
