Utility of Family Reports in Predicting Emergency Department Patient Alcohol Use in Tanzania.

Myriad reasons, including stigma, may prevent patients from self-reporting harmful use of alcohol in Tanzania. Family members may be more forthright but might not know the extent of the patient's alcohol use or suffer alcohol-related stigma as well. Our study aims to compare the reporting of patient alcohol use by emergency department patients themselves and their family members in Tanzania in order to describe the potential use of family reports as a proxy for patient self-reports. We conducted a secondary descriptive analysis of a prospective cohort of adult patients seeking treatment for injury and their family members. We evaluated alcohol use behavior, alcohol-related consequences, and alcohol-related stigma reported by 231 patients and 231 family members (both majority male, ages 25-45 years), measured by the Alcohol Use Disorders Identification Test (AUDIT), Perceived Alcohol Stigma (PAS) scale, and the Drinker Inventory of Consequences (DrInC). Alcohol use behavior concordance/discordance between patients and families was established, and alcohol use and perceived stigma were analyzed. More than 72% of patient-family pairs showed alcohol use (AUDIT) concordance. Receiver operating characteristic curve and regression analysis suggests family reports to be clinically relevant, significant, and potentially accurate markers of patient alcohol use (sensitivity: 95.10%, specificity: 69.77%). Findings support the existence of stigma toward alcohol in this context, with similar stigma levels of patients and family members. Family-reported patient alcohol use may be an accurate proxy for patient self-reporting. Further research is needed into stigma toward alcohol that is culturally appropriate and adopted.

Fluorodeoxyglucose positron emission tomography scans in patients with alcohol use disorder.

Diminished uptake of fluorodeoxyglucose (FDG) has been observed in patients with alcohol use disorder (AUD) but little statistical contrast of the regional brain deficits has been undertaken. This study examined prefrontal cortex inter-regional Brodmann area differences to delineate patterns associated with behavioral, neurotransmitter, and general toxicity hypotheses of cerebral involvement in AUD. We obtained data from FDG positron emission tomography (PET) and anatomical magnetic resonance imaging (MRI) for 87 patients with AUD and 41 age- and sex-matched healthy volunteers. Patients were alcohol dependent and had negative breathalyzer tests at the time of imaging. They were assessed with the Beck Depression Inventory, Alcohol Urge Questionnaire, Obsessive Compulsive Drinking Scale, Spielberger State/Trait Anxiety Scale, Buss-Durkee Hostility Inventory, and the Drinker Inventory of Consequences (DrInC). PET images were co-registered to MRI and both voxel×voxel statistical mapping and stereotaxic regions of interest were obtained. Compared with healthy volunteers, patients with AUD had lower relative metabolic rates in the frontal, temporal, and parietal lobes, localizable most prominently to the dorsolateral and nearly all orbital prefrontal cortex, superior temporal gyrus, and inferior parietal lobule. In contrast, metabolic rates in the medial orbitofrontal and anterior cingulate cortex, and the subcortical structures (thalamus, cerebellum, ventral striatum, and the dorsal raphe nucleus) in patients were significantly greater. The severity of alcohol-related consequences as assessed by the DrInC scale was most highly associated with lower metabolism in the caudate, dorsolateral prefrontal, frontopolar, and anteroposterior cingulate cortex. Despite widespread metabolic abnormalities, decreases in AUD were most marked in frontal executive areas, consistent with diminished impulse control, and increases were most prominent in the striatum and cingulate areas, consistent with a suppressed reward system.

An application of moderated nonlinear factor analysis to develop a commensurate measure of alcohol problems across four alcohol treatment studies

BackgroundSelf-report measures of alcohol problems are commonly included in studies evaluating treatment and recovery from alcohol use disorder (AUD), but no prior study has examined the replicability of the measurement of alcohol problems across studies with various measures and diverse samples. Further, it is unclear which items may be better indicators of alcohol problems for patient subgroups. In the present study, we integrated data from four large alcohol treatment studies to develop a commensurate measure of alcohol problems using moderated nonlinear factor analysis (MNLFA). MethodsData were from the COMBINE study, Project MATCH, the Relapse Replication and Extension Project (RREP), and the United Kingdom Alcohol Treatment Trial (UKATT), yielding a total sample size of 4414. MNLFA was carried out on the Drinker Inventory of Consequences (COMBINE, MATCH, RREP) and Alcohol Problems Questionnaire (UKATT). ResultsWe successfully created a 78-item commensurate measure of alcohol problems and examined differential item functioning (DIF) by study membership, time, and socio-demographic characteristics. Sixty-two items demonstrated intercept DIF, suggesting differences in rates of item endorsement for clients with the same underlying levels of alcohol problems across patient subgroups. Six items demonstrated loading DIF, suggesting differences in the extent to which the items were indicative of alcohol problems across patient subgroups. ConclusionsThe self-reported measurement of alcohol problems replicates across measures and diverse samples. Items with DIF have clinical implications for the treatment of AUD. Finally, MNLFA scores can be used to test substantive research questions across these studies.

Stability of Posttreatment Reductions in World Health Organization (WHO) Drinking Risk Levels and Posttreatment Functioning in Older Adults with DSM-5 Alcohol Use Disorder: Secondary Data Analysis of the Elderly Study.

Studies have found that reductions in World Health Organization (WHO) drinking risk levels may be a stable outcome of treatment for alcohol use disorder (AUD) and associated with functional improvements. The aim of this study was to investigate whether posttreatment reductions in WHO drinking risk levels are stable over time among older adults and associated with a decrease in consequences of drinking and AUD symptoms and improved quality of life. Participants. Individuals 60+years old, suffering from DSM-5 AUD (n=693), and seeking outpatient treatment. WHO drinking risk levels, prior to treatment and at all follow-up points up to 1year after treatment start, were assessed with Form 90. Outcomes at follow-up included consequences of drinking (Drinker Inventory of Consequences), quality of life (WHOQOL-BREF), and DSM-5 AUD symptoms (Mini International Neuropsychiatric Interview). Logistic regression and linear mixed models were used to examine the probability of maintaining risk-level reductions at follow-up and the association between risk-level reductions and outcomes, respectively. Reductions in risk levels were maintained over time (at least 1 level: OR 5.39, 95% CI 3.43, 8.47; at least 2 levels: OR 9.30, 95% CI 6.14, 14.07). Reductions were associated with reduced consequences of drinking and number of AUD symptoms, and minor, but statistically significant, improvements in quality of life. Maintaining reductions in WHO risk levels appears achievable for older adults seeking treatment for AUD. The small reduction of AUD symptoms and improvement of quality of life indicates that these reductions may not be adequate as the only treatment goal.

World Health Organization risk drinking level reductions are associated with improved functioning and are sustained among patients with mild, moderate and severe alcohol dependence in clinical trials in the United States and United Kingdom

To examine whether World Health Organization (WHO) risk-level reductions in drinking were achievable, associated with improved functioning and maintained over time among patients at varying initial alcohol dependence severity levels. Design and setting Secondary data analysis of multi-site randomized clinical trials: the US Combined Pharmacotherapies and Behavioral Interventions for Alcohol Dependence (COMBINE) study and the UK Alcohol Treatment Trial (UKATT). Individuals with alcohol dependence enrolled in COMBINE (n=1383; 68.8% male) and seeking treatment for alcohol problems in UKATT (n=742; 74.1% male). Interventions Naltrexone, acamprosate or placebo, and combined behavioral intervention or medication management in COMBINE. Social behavior network therapy or motivational enhancement therapy in UKATT. WHO risk-level reductions were assessed via the calendar method. Alcohol dependence was measured by the Alcohol Dependence Scale, the Leeds Dependence Questionnaire and the Diagnostic and Statistical Manual of Mental Disorders. Measures of functioning included alcohol-related consequences (Drinker Inventory of Consequences and Alcohol Problems Questionnaire), mental health (Short Form Health Survey) and liver enzyme tests. One- and two-level reductions in WHO risk levels in the last month of treatment were maintained at the 1-year follow-up [adjusted odds ratio (OR), 95% confidence interval (CI)= one-level reduction in COMBINE: 3.51 (2.73, 4.29) and UKATT: 2.65 (2.32, 2.98)] and associated with fewer alcohol-related consequences [e.g. B, 95% CI=one-level reduction COMBINE: -26.22 (-30.62, -21.82)], better mental health [e.g. B, 95% CI=one-level reduction UKATT: 9.53 (7.36, 11.73)] and improvements in γ-glutamyltransferase [e.g. B, 95% CI=one-level reduction UKATT: -89.77 (-122.50, -57.04)] at the end of treatment, even among patients with severe alcohol dependence. Results were similar when abstainers were excluded. Conclusions Reductions in World Health Organization risk levels for alcohol consumption appear to be achievable, associated with better functioning and maintained over time in both the United States and the United Kingdom.

The pattern of alcohol use and its relationship with consequences among problem alcohol users: A community-based cross-sectional study from India.

Background:Pattern of drinking has a strong bearing on alcohol-related negative consequences. Very few studies from India have assessed this relationship using any standardized instrument.Aim:The current study aims to assess the relationship between pattern of alcohol use and negative consequences among problem alcohol users using a standardized instrument.Materials and Methods:This cross-sectional, observational study using snowball sampling technique was conducted among 75 participants in an urban slum of a metropolitan city of India. Screening of the participants was done by the World Health Organization Alcohol, Smoking and Substance Involvement Screening Test (WHO-ASSIST). Alcohol use details and alcohol-related adverse consequences were obtained by a semi-structured questionnaire and Drinker Inventory of Consequences (DrInC) inventory, respectively. Descriptive statistics, Chi-square test, and logistic regression test were used to analyze the data.Results:There was a significant association between high total DrInC score and ≥3 subscale scores with employment status, percentage of total family income spent on alcohol, source of income to procure alcohol, amount of alcohol, morning drinking, alcohol use for relaxation, and drinking throughout the day (Chi-square test). Age ≤35 years, current unemployment/part-time employment state, spending ≥25% of total family income on alcohol, family history, and drinking throughout the day were more likely to have high total DrInC score and ≥2 subscale scores (logistic regression analysis).Conclusion:A large proportion of the participants were suffering significantly from alcohol-related consequences but still were not receiving any treatment. It emphasizes the need for more epidemiological studies in this area for its treatment and policy-level implication.

Cross-Culture Adaptation and Psychometric Properties of the DrInC Questionnaire in Tanzanian Swahili.

Aims: To develop Swahili versions of the Drinker Inventory of Consequences (DrInC) and evaluate its psychometric properties among a mixed population in Tanzania.Methods: A Swahili version of the DrInC was developed by a panel of bilingual Swahili and English speakers through translation and back-translation. The translated DrInC was administered to a sample of Tanzanian injury patients and a sample of the general population. The validity and reliability of the scale were tested using standard statistical methods.Results: The translated version of the DrInC questionnaire was found to have outstanding domain coherence and language clarity. The tested scale and subscales have adequate reliability (>0.85). Confirmatory factor analysis (CFA) confirmed the five-factor solution by yielding adequate results. DrInC score is statistically significantly correlated with alcohol consumption quantity and the AUDIT score, suggesting that DrInC is able to predict alcohol use as well.Conclusions: This study presents the first validation of the DrInC questionnaire with injury patients and a general population and the first adaptations of the DrInC questionnaire in the Tanzanian and Swahili setting. DrInC instrument was found to have satisfactory psychometric properties, resulting in a new medical and social research tool in this setting.

Profiles of recovery from alcohol use disorder at three years following treatment: can the definition of recovery be extended to include high functioning heavy drinkers?

Recovery from alcohol use disorder (AUD) is often narrowly defined by abstinence from alcohol and improvements in functioning (e.g. mental health, social functioning, employment). This study used latent profile analysis to examine variability in recovery outcomes, defined by alcohol use, alcohol-related problems and psychosocial functioning at 3years following treatment. Secondary analysis investigated pre-treatment, post-treatment and 1- and 3-year post-treatment covariate predictors of the latent profiles. Secondary analysis of data from a randomized clinical trial. United States. We used data from the out-patient arm of Project MATCH (n=806; 29.7% female, 22.2% non-white). Recovery was defined by latent profile analyses including measures of psychosocial functioning and life satisfaction (Psychosocial Functioning Inventory), unemployment and mental health (Addiction Severity Index), alcohol and other drug use (Form 90) and alcohol-related consequences (Drinker Inventory of Consequences) 3 years following treatment. Mixture modeling was used to examine correlates of profiles. We identified four profiles at 3years following treatment: (1) poor functioning frequent heavy drinkers, (2) poor functioning infrequent heavy drinkers, (3) high functioning occasional heavy drinkers and (4) high-functioning infrequent non-heavy drinkers. There were relatively few differences on indicators of functioning and treatment-related variables between the high functioning infrequent non-heavy drinkers and the high-functioning occasional heavy drinkers, other than high-functioning occasional heavy drinkers having lower alcohol dependence severity [odds ratio (OR)=0.94, 95% confidence interval (CI)=0.90, 0.98], fewer post-treatment coping skills (OR=0.54, 95% CI=0.32, 0.90) and lower 3-year post-treatment abstinence self-efficacy (OR=0.37, 95% CI=0.28, 0.49) and Alcoholics Anonymous (AA) involvement (OR=0.87, 95% CI=0.85, 0.99). The two high-functioning profiles showed the greatest improvements in functioning from baseline through the 3-year follow-up, whereas the low-functioning profiles showed the least amount of improvement. High-functioning occasional heavy drinkers had higher purpose in life than the poor-functioning profiles. Some individuals who engage in heavy drinking following treatment for alcohol use disorder may function as well as those who are mostly abstinent with respect to psychosocial functioning, employment, life satisfaction and mental health.

Ascertaining the relationships between the trajectories of specific categories of alcohol-related negative consequences and subsequent drinking behavior.

The first year following alcohol use disorder (AUD) treatment has been identified as a period of high risk for relapse and an important timeframe for enquiry regarding alcohol-related behavior change and its maintenance. In addition, at least among individuals with AUD, alcohol use and negative consequences have been shown to be reciprocally related. A commonly used measure of alcohol-related negative consequences is the Drinker Inventory of Consequences (DrInC). Investigations of specific categories of alcohol-related negative consequences and their trajectories, however, have been lacking. Given this background, the purpose of this study was to: follow the course of the 5 DrInC categories of alcohol-related negative consequences over the first year post-AUD treatment initiation; investigate whether these trajectories varied by gender, age, and/or treatment condition; examine the relationships between these trajectories and subsequent drinking behavior; and investigate whether these relationships varied by gender, age, and/or treatment condition, via secondary data analyses. Data from the outpatient arm of Project MATCH (n = 952) were utilized. Study results revealed that the trajectory of each DrInC category was indicative of improved alcohol-related problems across the first year posttreatment initiation. Specific DrInC categories varied as a function of gender, age, and treatment condition, and the trajectories were predictive of subsequent drinking behavior. Specifically, higher intercepts during the treatment period were associated with poorer drinking behavior 1 year later. Alternatively, steeper negative slopes were associated with improved drinking behavior. Some of these relationships were modified by gender, age, and treatment condition. It was concluded that assessing alcohol-related negative consequences during the first year posttreatment initiation period has clinical utility. (PsycINFO Database Record

Under the influence of Facebook? Excess use of social networking sites and drinking motives, consequences, and attitudes in college students.

Background and aimsExcessive use of social networking sites (SNS) has recently been conceptualized as a behavioral addiction (i.e., “disordered SNS use”) using key criteria for the diagnosis of substance dependence and shown to be associated with a variety of impairments in psychosocial functioning, including an increased risk of problem drinking. This study sought to characterize associations between “disordered SNS use” and attitudes towards alcohol, drinking motives, and adverse consequences resulting from alcohol use in young adults.MethodsUndergraduate students (n = 537, 64.0% female, mean age = 19.63 years, SD = 4.24) reported on their use of SNSs and completed the Alcohol Use Disorders Identification Test, Temptation and Restraint Inventory, Approach and Avoidance of Alcohol and Drinking Motives Questionnaires, and Drinker Inventory of Consequences.ResultsRespondents meeting previously established criteria for “disordered SNS use” were significantly more likely to use alcohol to cope with negative affect and to conform to perceived social norms, reported significantly more conflicting (i.e., simultaneous positive and negative) attitudes towards alcohol, and had experienced significantly more, and more frequent adverse consequences from drinking in their inter- and intrapersonal, physical, and social functioning, compared to individuals without problems related to SNS use.Discussion and conclusionsFindings add to an emerging body of literature suggesting a link between excess or maladaptive SNS use and problems related to alcohol in young adults and point to emotion dysregulation and coping motives as potential shared risk factors for substance and behavioral addictions in this demographic.

The Effects of as-Needed Nalmefene on Patient-Reported Outcomes and Quality of Life in Relation to a Reduction in Alcohol Consumption in Alcohol-Dependent Patients.

BackgroundThe objective of this article was to investigate the effect of as-needed nalmefene on health-related quality of life (HRQoL) in patients with alcohol dependence, and to relate changes in drinking behavior and status to HRQoL outcomes.MethodsThis post hoc analysis was conducted on a pooled subgroup of patients with at least a high drinking risk level (men: >60 g/day; women: >40 g/day) who participated in one of two randomized controlled 6-month studies, ESENSE 1 and ESENSE 2. Patients received nalmefene 18 mg or placebo on an as-needed basis, in addition to a motivational and adherence-enhancing intervention (BRENDA). At baseline and after 12 and 24 weeks questionnaires for the Medical Outcomes Study (MOS) 36-item Short-Form Health Survey (SF-36), European Quality of life-5 Dimensions (EQ-5D) and the Drinker Inventory of Consequences (DrInC-2R) were completed.ResultsThe pooled population consisted of 667 patients (nalmefene: 335; placebo: 332), with no notable between-group differences in baseline patient demographics/characteristics. At week 24, nalmefene had a superior effect compared to placebo in improving SF-36 mental component summary scores (mean difference [95% CI], p-value: 3.09 [1.29, 4.89]; p=0.0008), SF-36 physical component summary scores (1.23 [0.15, 2.31]; p=0.026), EQ-5D utility index scores (0.03 [0.00, 0.06]; p=0.045), EQ-5D health state scores (3.46 [0.75, 6.17]; p=0.012), and DrInC-2R scores (-3.22 [-6.12, 0.33]; p=0.029). The improvements in SF-36 mental component summary scores at week 24, and the DrInC-2R total score change from baseline to week 24, were significantly correlated to reductions in heavy drinking days and total alcohol consumption at week 24.ConclusionsAs-needed nalmefene significantly improved almost all patient-reported HRQoL measures included in SF-36 and EQ-5D compared with placebo. These HRQoL gains were significantly correlated to reduced drinking behavior, as determined by reductions in heavy drinking days and total alcohol consumption.

EPA-0255 – Clinical relevance of as-needed treatment with nalmefene in alcohol dependent patients

The opioid system modulator nalmefeneis the first pharmacological therapy approved in the European Union for reduction of alcohol consumption. To evaluate the clinical relevance of the reduction of alcohol consumption in patients with at least high drinking risk level at screening and randomisation from the two, identically designed, randomised controlled 6-month studies ESENSE1 (NCT00811720) and ESENSE2 (NCT00812461) of nalmefene versus placebo. Study medication was taken as-needed. All patients received a motivational and adherence-enhancing intervention (BRENDA). Response criteria were based on alcohol consumption at month 6 and Clinical Global Impression – Severity of Illness/Improvement (CGI-S/I), Short Form Health Survey version 2 (SF-36) mental component summary(MCS) scores at week 24. Clinical relevance was also studied using the Drinker Inventory of Consequences (DrInC), Alcohol Dependence Scale (ADS), and liver function variables. Pooled study population: 667 patients (placebo N=332; nalmefene N=335). The proportion of responders was higher in the nalmefene group than in the placebo group with odds ratios for response consistently significantly (p<0.05) in favour of nalmefene. The difference in the proportions of responders translated to numbers-needed-to-treat ranging from 6 to 10. Significant differences to placebo (p<0.05) in the SF-36 MCS and physical component summary score, ADS, DrInC, CGI-I/S and liver enzymes further supported the clinical relevance of the treatment effect. In view of the immense alcohol-related burden to society, the harm to the individual and the large treatment gap partly due to a reluctance to engage in abstinence, the effect of nalmefene is clearly clinically relevant.

Perturbation of the Glutamate–Glutamine System in Alcohol Dependence and Remission

As acute ethanol exposure inhibits N-methyl-D-aspartate glutamate (Glu) receptors, sudden withdrawal from chronic alcohol use may lead to an increased activation of these receptors with excitotoxic effects. In the longer term, brain levels of Glu and its metabolites, such as glutamine (Gln), are likely to be chronically altered by alcohol, possibly providing a measure of overall abnormal Glu-Gln cycling. However, few studies have assessed concentrations of these metabolites in clinical populations of individuals with alcohol use disorders. Glu and Gln levels were compared in groups of 17 healthy controls and in 13 participants with alcohol dependence. Within the alcohol-dependent group, seven participants had current alcohol use disorder (AUD), and six had AUD in remission for at least 1 year (AUD-R). Neurometabolite concentrations were measured with proton magnetic resonance spectroscopy ((1)H-MRS) in a predominantly gray matter voxel that included the bilateral anterior cingulate gyri. Tissue segmentation provided an assessment of the proportion of gray matter in the (1)H-MRS voxel. The Drinker Inventory of Consequences (DrInC) and Form-90 were administered to all participants to quantify alcohol consequences and use. Glu level was lower and Gln level was higher in the AUD and AUD-R groups relative to the control group; creatine, choline, myo-inositol, and total N-acetyl groups, primarily N-acetylaspartate did not differ across groups. These results were not confounded by age, sex, or proportion of gray matter in the (1)H-MRS voxel. Neurometabolite concentrations did not differ between AUD and AUD-R groups. Subsequent regressions in the combined clinical group, treating voxel gray matter proportion as a covariate, revealed that total score on the DrInC was positively correlated with Gln but negatively correlated with both Glu and gray matter proportion. Regression analyses, including DrInC scores and smoking variables, identified a marginal independent effect of smoking on Gln. The current findings of higher Gln and lower Glu in the combined AUD and AUD-R groups might indicate a perturbation of the Glu-Gln cycle in alcohol use disorders. The absence of differences in mean Glu and Gln between the AUD and AUD-R groups suggests that altered Glu-Gln metabolism may either predate the onset of abuse or persist during prolonged abstinence.

Change Plan as an Active Ingredient of Brief Motivational Interventions for Reducing Negative Consequences of Drinking in Hazardous Drinking Emergency-Department Patients

Few studies have examined the effects of brief motivational intervention components, such as change-plan completion, on treatment outcomes. This secondary analysis of an opportunistically recruited emergency-department sample of hazardous injured drinkers examines the potential predictive role of an alcohol-related change plan on treatment outcomes after accounting for pretreatment readiness. Written change plans were independently rated. A mediational analysis framework tested directional hypotheses between pretreatment readiness, change plan, and treatment outcomes using linear regressions. The baseline total Drinker Inventory of Consequences (DrInC) score was covaried on 12-month DrInC total score, in all analyses. Participants who completed a brief motivational intervention and a change plan were included (N = 333). Pretreatment readiness was negatively associated with alcohol consequences at 12 months, (beta = -.09, t(254) = -2.07, p < .05, and good-quality change plans, (beta = .18, t(320) = 4.37, p < .001. With change plan and readiness in the same model, the relationship between readiness and treatment outcomes became nonsignificant, but change plan remained a significant predictor of treatment outcomes in the expected direction, beta = -.17, t(254) = -2.89, p < .01. Follow-up generalized linear modeling including an interaction term (change plan and pretreatment readiness) revealed that those with high readiness and a good-quality change plan versus those with low readiness and a poor-quality change plan had better-than-predicted outcomes for either readiness or change plan alone. Study findings suggest that the change plan in brief motivational intervention may be an active ingredient of treatment associated with better outcomes over and above the influence of pretreatment readiness.

Estimating driver risk using alcohol biomarkers, interlock blood alcohol concentration tests and psychometric assessments: initial descriptives

To identify alcohol biomarker and psychometric measures that relate to drivers' blood alcohol concentration (BAC) patterns from ignition interlock devices (IIDs). In Alberta, Canada, 534 drivers, convicted of driving under the influence of alcohol (DUI), installed IIDs and agreed to participate in a research study. IID BAC tests are an established proxy for predicting future DUI convictions. Three risk groups were defined by rates of failed BAC tests. Program entry and follow-up blood samples (n = 302, 171) were used to measure phosphatidyl ethanol (PETH), carbohydrate deficient transferrin (%CDT), gamma glutamyltransferase (GGT) and other biomarkers. Program entry urine (n = 130) was analyzed for ethyl glucuronide (ETG) and ethyl sulphate (ETS). Entry hair samples were tested for fatty acid ethyl esters (FAEE) (n = 92) and ETG (n = 146). Psychometric measures included the DSM-4 Diagnostic Interview Schedule Alcohol Module, Alcohol Use Disorders Identification Test (AUDIT), the time-line follow-back (TLFB), the Drinker Inventory of Consequences (DRINC) and the Temptation and Restraint Inventory (TRI). Except for FAEE, all alcohol biomarkers were related significantly to the interlock BAC test profiles; higher marker levels predicted higher rates of interlock BAC test failures. PETH, the strongest with an overall analysis of variance F ratio of 35.5, had significant correlations with all nine of the other alcohol biomarkers and with 16 of 19 psychometric variables. Urine ETG and ETS were correlated strongly with the IID BAC tests. The findings suggest that several alcohol biomarkers and assessments could play an important role in the prediction and control of driver alcohol risk when re-licensing.

Reliability and Validity of the Alcohol Short Index of Problems and a Newly Constructed Drug Short Index of Problems

This study evaluated the psychometric properties of the 15-item alcohol Short Index of Problems (SIP) instrument and those of a newly constructed 15-item drug Short Index of Problems (SIP-D) instrument in 277 newly entered substance-abuse patients. The SIP is derived from the longer, 50-item Drinker Inventory of Consequences (DrInC), which was designed to assess adverse consequences of alcohol use. The SIP-D was constructed by substituting the term "drug use" for the term "drinking" in each SIP item. A 3-month recall interval was employed. Factor analyses of each of the instruments revealed similar solutions, with only one main factor accounting for the majority of variance. Nonparametric item response theory methods produced the same finding. Internal consistency reliability estimates for the SIP and SIP-D total scores were .98 and .97, respectively. Concurrent validity was demonstrated by examining the correlations of the total scores for each of the instruments with the recent summary indexes of the newly revised Addiction Severity Index (ASI-Version 6): alcohol, drug, medical, economic, legal, family/social, and psychiatric problems. This study is the first to confirm the psychometric validity of the SIP when used as an independent instrument unembedded within the DrInC. The study also supports the use of the SIP-D as a brief measure of adverse consequences of drug use. The findings strongly support the unidimensional structure of both measures.

Gender Differences in Alcohol Use and Alcohol-Related Problems: Do They Hold for Lesbians and Gay Men?

ABSTRACT Research regarding gender differences in alcohol use and alcohol-related problems finds that men drink more and suffer higher rates of alcohol-related problems compared with women. The purpose of the current study was to examine whether these differences also exist between lesbians and gay men. A sample of 335 lesbians and gay men were recruited through lesbian and gay events, Listservs, and friendship networks. Items from the National Household Survey on Drug Abuse (Substance Abuse and Mental Health Services Administration, 2000) measured alcohol consumption. The Michigan Alcoholism Screening Test (Selzer, 1971) and the Drinker Inventory of Consequences (Miller, Tonigan, & Longabaugh, 1995) measured alcohol-related problems. Gay men tended to drink more often than lesbians, but there were no significant gender differences regarding alcohol-related problems. Research, theoretical, and clinical implications are discussed.

Web-based norms for the Drinker Inventory of Consequences from the Drinker's Checkup

To date, the only published norms for the Drinker Inventory of Consequences (DrInC) have come from a sample of heavy drinkers in Project MATCH (Matching Alcoholism Treatments to Client Heterogeneity) who were enrolling in a treatment program. We have generated an additional set of norms for the DrInC based on a large sample ( N = 1,564) of heavy drinkers who have completed the DrInC as part of a Web-based brief motivational intervention, the Drinker's Checkup (DCU; www.drinkerscheckup.com). Although these drinkers were not seeking formal treatment, they were concerned enough about their drinking to pay $25 to use the DCU. Comparing the means and decile scores for lifetime and recent total scores and subscale scores between the DCU and MATCH samples revealed that DrInC scores for the DCU sample were significantly lower than the MATCH sample. These findings have implications for giving normative feedback using the DrInC with non-treatment-seeking populations. The use and limitations of these findings are discussed.

Psychometrics of the Drinker Inventory of Consequences (DrInC)

The Drinker Inventory of Consequences (DrInC) was developed for Project MATCH to assess the consequences of drinking in five domains. The present study, using baseline data from the 1382 participants involved in the COMBINE Study, analyzed the psychometrics of the 50-item DrInC and its shorter form, the 15-item SIP. Findings indicate the DrInC is reliable, valid, and clinically useful and that DrInC subscales are internally consistent and non-redundant. In an examination of the shorter version of the DrInC, findings suggest that the SIP is suitable when assessing the overall level of drinking-related consequences.

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

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. 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. 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. 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. 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.
