Alcohol abuse and dependence in an urban primary care clinic in Nigeria.

A two-stage epidemiological survey was conducted in an urban walk-in clinic in Nigeria to detect, among other disorders, the prevalence of alcohol abuse and dependence using DMS-IIIR criteria. At the first stage, respondents were administered the 12-item General Health Questionnaire and the Alcohol Use Disorders Identification Test (AUDIT). A proportion of the respondents were selected for detailed interview at the second stage using the Composite International Diagnostic Interview (CIDI). An estimated 1.7% of this sample met the criteria for alcohol abuse or dependence. All the identified cases were males, thus giving an estimated prevalence of 5.2% in males. In this setting, the AUDIT performed poorly as a screening instrument. It has a sensitivity of 32% but a specificity of 93%. Apart from reasons relating to the low base rates of the disorders under investigation, cultural factors influencing the ways alcohol use are perceived may explain this poor performance.     

WHO Study on the reliability and validity of the alcohol and drug use disorder instruments: overview of methods and results

The WHO Study on the reliability and validity of the alcohol and drug use disorder instruments is an international study which has taken place in 12 centres in ten countries, aiming to test the reliability and validity of three diagnostic instruments for alcohol and drug use disorders: the Composite International Diagnostic Interview (CIDI), the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and a special version of the Alcohol Use Disorder and Associated Disabilities Interview schedule-alcohol/drug-revised (AUDADIS-ADR). The purpose of the reliability and validity (R&V) study is to further develop the alcohol and drug sections of these instruments so that a range of substance-related diagnoses can be made in a systematic, consistent, and reliable way. The study focuses on new criteria proposed in the tenth revision of the International Classification of Diseases (ICD-10) and the fourth revision of the diagnostic and statistical manual of mental disorders (DSM-IV) for dependence, harmful use and abuse categories for alcohol and psychoactive substance use disorders. A systematic study including a scientifically rigorous measure of reliability (i.e. 1 week test-retest reliability) and validity (i.e. comparison between clinical and non-clinical measures) has been undertaken. Results have yielded useful information on reliability and validity of these instruments at diagnosis, criteria and question level. Overall the diagnostic concordance coefficients (kappa, κ) were very good for dependence disorders (0.7–0.9), but were somewhat lower for abuse and harmful use categories. The comparisons among instruments and independent clinical evaluations and debriefing interviews gave important information about possible sources of unreliability, and provided useful clues on the applicability and consistency of nosological concepts across cultures.     

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

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

Validation of the Alcohol Use Identification Test in a Prison Sample Living in the Arabian Gulf Region

The purpose of this study was to assess the utility of the Arabic translation of the Alcohol Use Disorders Identification Test (AUDIT) among a sample of male Muslim prisoners (N = 107) in Dubai, United Arab Emirates (UAE). Confirmatory factor analysis indicated a two-factor model to be the best fit of the data. Good internal reliability (α =.91) and predictive validity were also observed. While the limitations of the study are observed, these promising results suggest that the Arabic version of the AUDIT is a reliable and sound measure of alcohol use disorders among prisoners in the UAE.     

The validity of an Australian modification of the AUDIT questionnaire

The Alcohol Use Disorders Identification Test (AUDIT) has been used widely and is reported to be superior to conventional questionnaires in detection of current hazardous and harmful alcohol use. We assessed the validity of an Australian modification of the AUDIT (the AusAUDIT), which has been employed widely in Australian and New Zealand early intervention programmes. We used a cross-sectional study of 370 subjects from the follow-up phase of a randomized controlled trial of early intervention to reduce hazardous alcohol consumption. Scores on the AusAUDIT were compared against 12-month ICD-10 diagnoses of harmful alcohol use and dependence, as determined by the Composite International Diagnostic Interview, and against self-report of alcohol consumption exceeding Australian National Health and Medical Research Council (NH&MRC) recommended limits. AusAUDIT had good internal consistency and discriminated significantly between persons meeting criteria for ICD-10 alcohol use disorders, and drinkers who did not. At currently recommended cut-off scores, AusAUDIT detected more than 85% of people meeting criteria for ICD-10 alcohol use disorders, or drinking over NH&MRC recommended limits, but its specificity was limited (29% in men, and 58% in women for drinking over NH&MRC limits). No subset of questions performed as well as the full AusAUDIT in detection of drinking problems, but the alcohol consumption items provided a reasonable screen for drinking over NH&MRC limits. We conclude that AusAUDIT is effective in detecting problematic drinking, but positive cases should be confirmed by clinical assessment. The findings illustrate the need for validation of questionnaire modifications, and the difficulty in increasing test sensitivity without reducing specificity. \[Degenhardt LJ, Conigrave KM, Wutzke SE, Saunders JB.

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

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

Effects of item sequence on the performance of the AUDIT in general practices

BACKGROUND: One important task in identifying subjects with alcohol use disorders (AUDs) in the general medical practice setting is the development of effective screening instruments. Sensitivity of screening questionnaires might differ according to the introductory items. This study compares two versions of the alcohol use disorders identification test (AUDIT) with varied item sequence randomly applied to patients derived from a sample of general practitioners (GP) patients. METHODS: Participants were recruited from general practices in two northern German cities; they received two different versions of the AUDIT, one group receiving the original version starting with three items addressing frequency and quantity of alcohol use (AUDIT1), and a second group receiving a version in which these items were put at the end of the questionnaire (AUDIT2). In total, 10.803 screenings were conducted (refusal rate: 5%). Alcohol use disorders were diagnosed using the Munich-Composite International Diagnostic Interview (M-CIDI). RESULTS: Logistic regression analysis revealed that AUDIT1 subjects had higher scores in the consumption items of the AUDIT, whereas AUDIT2 subjects scored higher on items focussing on symptoms of alcohol dependence or abuse. CONCLUSION: The sequence upon which items of the AUDIT are presented influences the report of drinking patterns and symptoms of alcohol use disorders in GP patients.     

Screening adolescents for problem drinking: performance of brief screens against DSM-IV alcohol diagnoses

OBJECTIVE: The performance of three brief screens, the CAGE, TWEAK and Alcohol Use Disorders Identification Test (AUDIT), was evaluated against a DSM-IV diagnosis of alcohol abuse or dependence in an adolescent sample. METHOD: Adolescents (13-19 years old) who presented to an emergency department for treatment of an injury, and who tested negative for blood alcohol concentration at time of admission, were administered a structured diagnostic interview and modified versions of the CAGE, TWEAK and AUDIT. RESULTS: Of the 415 adolescents for whom complete data were available, 18% met criteria for a DSM-IV alcohol use disorder according to the Diagnostic Interview Schedule for Children (version 2.3). Teens who reported alcohol use in the last year (n = 261, 58% male, 71% white) were included in analyses that compared the performance of the three screening instruments. Receiver Operating Characteristic analysis indicated that the AUDIT demonstrated the best performance across the range of its cut-scores, with optimal performance at a cut-score of 4. The TWEAK performed optimally at a cut-score of 2 and the CAGE at a cut-score of 1. CONCLUSIONS: Routine alcohol screening among adolescents seen in a hospital setting is indicated. Two important directions for future research include the identification of adolescent-specific alcohol screening items, and the validation of an adolescent-specific definition of problem drinking that addresses limitations of DSM-IV alcohol diagnoses when applied to adolescents.     

Identifying young people who drink too much: the clinical utility of the five-item Alcohol Use Disorders Identification Test (AUDIT)

The current study investigated the patterns and consequences of alcohol use among young people and their perceptions of associate health risk, and explored the clinical utility of the five-itemversion of the Alcohol Use Disorders Identification Test (AUDIT) in screening young people for hazardous drinking. A cross-sectional sample of 393 young people aged 16-19 years were accessed through two tertiary colleges in South London and self-completed an anonymous, confidential questionnaire recording the five-item AUDIT, patterns of alcohol consumption, hazardous consequences and perception of associate health risk. Over 90% of the sample reported drinking alcohol regularly, commonly excessive weekend use and related physical, psychological and social consequences. A significant minority (20.4% of males, 18.0% of females) reported consumption of alcohol in excess of UKrecommended limits, while almost a third (34.2%of males, 30.2%of females) reported scores in the 'hazardous' range of the five-item AUDIT. However, the majority had little perception of associate health risk, perceiving their use to be 'light' and unproblematic. Only one in 10 of those drinking at 'hazardous' levels recognized their alcohol use as problematic, most believing the hazardous consequences of this use were acceptable. Self-reported patterns of alcohol consumption (except age first used) and total number of psychological and social hazardous consequences were found to significantly predict AUDIT scores using linear regression analysis. Therefore the five-item AUDIT appears to have predictive validity, reflecting self-reported alcohol consumption, perception of associate health risk and hazardous consequences among young people. It is concluded that it may consequently have clinical utility as a simple screening tool (suitable for use by a variety of professionals in contact with young people) for the identification of hazardous alcohol consumption among this population. \[Miles H, Winstock A, Strang J.

Screening for hazardous alcohol use and dependence in psychiatric in-patients using the AUDIT questionnaire

The Alcohol Use Disorders Identification Test (AUDIT) has been used to screen for hazardous and harmful alcohol consumption among general hospital populations but not in psychiatric patients. Using the AUDIT, we assessed alcohol use in patients with four major types of psychiatric disorder, namely mood, adjustment, anxiety and psychotic disorders. Nine hundred and ninety consecutive admissions to the psychiatric units of two hospitals during a 12-month period underwent assessment. In each diagnostic group a high proportion of patients was alcohol-dependent. Among those with mood disorders 25.4% of men were alcohol-dependent, compared with 16.3% of women, while 34.5% of men with anxiety disorder were alcohol-dependent compared with 25.0% of women. Both gender differences were statistically significant. The differences were even greater for adjustment disorder (44.4% vs. 14.5%) and psychosis (29.2% and 4.2%, respectively). More men than women with anxiety disorder were classified as hazardous (24.1%vs. 11.7%) or harmful drinkers (13.8%vs. 3.3%), but for the other diagnostic groupings the percentages in these drinking categories were more nearly similar. Thus, there is a high rate of excessive alcohol consumption in people with psychiatric disorders, especially males. Such individuals may be particularly vulnerable to complications of alcohol misuse such as suicide and exacerbation of their disorder. The potential for decreased severity of psychiatric symptoms and a reduction in the number of hospital admissions following cessation or reduction in alcohol consumption is considerable. The AUDIT is a simple screening device for investigating alcohol use and dependence, and offers a means of initiating intervention in this population.

Application of the Transtheoretical Model of change: psychometric properties of leading measures in patients with co-occurring drug abuse and severe mental illness

People with severe mental illness (SMI) have high rates of substance use disorders. The Transtheoretical Model (TTM) is a framework for understanding behavior change. There are five leading measures associated with the TTM - University of Rhode Island Change Assessment, Processes of Change Scale, Decisional Balance Scale, Abstinence Self-Efficacy Scale, and Temptation to Use Drugs Scale. While these measures have been found to be reliable and valid in primary substance abusers, it is unknown if these measures are relevant in people with co-occurring SMI and substance use disorders (SUD). We evaluated the psychometric properties of these measures in a sample (n=240) of people with co-occurring disorders. Participants met DSM-IV criteria for schizophrenia/schizoaffective disorder or non-psychotic affective disorder, and current cocaine dependence or cocaine dependence in remission. All subscales showed good reliability and validity in the total sample. Analyses within diagnostic groups showed good reliability and validity in most groups, with some falling off in the affective disorders and remitted cocaine dependence groups. Overall, findings support the use of these measures in people with co-occurring disorders.     

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

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

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

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

Alcohol Use Disorders Identification Test (AUDIT) scores are elevated in antipsychotic-induced hyperprolactinaemia

Hyperprolactinaemia in antipsychotic treated patients with schizophrenia is a consequence of D2 receptor (DRD2) blockade. Alcohol use disorder is commonly comorbid with schizophrenia and low availability of striatal DRD2 may predispose individuals to alcohol use. In this pilot study we investigated whether hyperprolactinaemia secondary to pharmacological DRD2 blockade was associated with alcohol use disorder in 219 (178 males and 41 females) patients with schizophrenia. Serum prolactin determinations were made in patients diagnosed with schizophrenia and maintained on antipsychotic agents. Clinical assessment included demographics, family history and administration of the AUDIT (Alcohol Use Disorders Identification Test). Higher AUDIT scores were associated with prolactin-raising antipsychotic medication (n=106) compared with prolactin-sparing medication (n=113). Risperidone (n=63) treated patients had higher AUDIT scores and prolactin levels than those on other atypical antipsychotics (n = 113). Across the entire sample, patients with a prolactin greater than 800 mIU/L had higher AUDIT scores and were more likely to exceed the cut-off score for harmful and hazardous alcohol use. These differences were not explained by potential confounds related to clinical features and demographics, comorbidity or medication side-effects. These data suggest that by lowering dosage, or switching to another antipsychotic agent, the risk for alcohol use disorder in those with schizophrenia may be reduced. This hypothesis requires testing using a prospective methodology.     

Construct validity of the MAST and AUDIT with multiple offender drunk drivers

The construct validity of the Michigan Alcoholism Screening Test (MAST) and the Alcohol Use Disorders Identification Test (AUDIT) in screening for current DSM-IV alcohol dependence disorders with persons convicted of multiple offenses of Driving Under the Influence (DUI) is evaluated. These tests were administered to 126 DUI offenders presenting for court-ordered inpatient treatment at an agency. DSM-IV alcohol disorders are evaluated for a representative subset of clients in this program using National Longitudinal Alcohol Epidemiologic Surveys' DSM-IV Alcohol Dependence Diagnostic Criteria and Associated Questionnaire Items. Both instruments exhibit acceptable internal consistency. The MAST and The AUDIT correlate moderately well with each other (r=0.617). The MAST correlates more highly (r=0.602) than the AUDIT (r=0.432) with DSM-IV. Future research should examine if the results reported here apply to other multiple offender DUI programs. It is recommended that such programs employing test instruments evaluate their construct validity in a similar method.     

The structure of alcohol dependence in the community

BACKGROUND: Although dependence on alcohol appears to be a reliable unitary construct, abuse has not found a similar level of support as a separate construct. This paper describes a confirmatory factor analysis of the DSM-IV alcohol abuse and dependence criteria in a general population sample. METHODS: Data from alcohol drinkers (n = 7746) were obtained from a cross-sectional study of a large, representative sample of the Australian general population. One- and two-factor solutions for the DSM-IV criteria for abuse and dependence (assessed by CIDI-Auto) were compared using confirmatory factor analysis. RESULTS: Approximately 74% of Australians had used alcohol 12 or more times in the past year and 19% met at least one DSM-IV alcohol abuse or dependence criterion. Overall 6% met criteria for an alcohol use disorder (1.9% abuse, 4.1% dependence). More men than women met criteria for an alcohol use disorder and the prevalence of alcohol use disorders decreased with increasing age. Both one- and two-factor solutions from the confirmatory factor analyses provided an adequate fit to the data for the overall sample. The correlation between the abuse and dependence factors in the two-factor model was extremely high (0.95). CONCLUSION: Alcohol abuse and dependence criteria were most parsimoniously described by a single continuous construct incorporating all eleven abuse and dependence criteria.     

Beyond alcoholism: identifying older,at-risk drinkers in primary care

OBJECTIVE: To evaluate the validity and reliability of two self-report instruments: the Alcohol-Related Problems Survey (ARPS) and its shorter version the Short ARPS (shARPS) that identify older persons whose use of alcohol alone or with their comorbidities may be placing them at risk for or causing them harm. METHOD: We compared the two measures against a "LEAD" (longitudinal evaluation done by experts employing all available data) standard among a sample of 166 drinkers aged 60 years and older in 10 internal medicine clinics. The LEAD standard included a medical record review, a clinical interview and a telephone interview with a collateral informant. We tabulated reasons the LEAD identified subjects as harmful or hazardous drinkers. We also compared the Alcohol Use Disorders Identification Test (AUDIT) and the Short Michigan Alcoholism Screening Test-Geriatric Version (SMAST-G) to the LEAD. RESULTS: Sensitivity and specificity of the ARPS and the shARPS as compared to the LEAD were 93% and 63%, and 92% and 51%, respectively. After minor changes were made in the scoring rules, specificity increased to 66% for both the ARPS and shARPS while sensitivity remained stable, 93% and 91%. Harmful and hazardous drinkers were most often identified because of alcohol use with comorbidities, symptoms, and medication use. Sensitivity and specificity of the AUDIT and the SMAST-G as compared to the LEAD were 28% and 100%, and 52% and 96%, respectively. CONCLUSIONS: The ARPS and shARPS are quite sensitive in identifying older drinkers with a spectrum of alcohol use disorders. They are more sensitive than the AUDIT and the SMAST-G in identifying older persons who may be at risk or experiencing harm as a result of their alcohol use and comorbidities. They also provide information on specific risks associated with alcohol use not obtained by other screening measures and may therefore facilitate interventions by busy clinicians to reduce such risks.     

The reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) in a German general practice population sample

OBJECTIVE: Our goal was to analyze the retest reliability and validity of the Alcohol Use Disorders Identification Test (AUDIT) in a primary-care setting and recommend a cut-off value for the different alcohol-related diagnoses. METHOD: Participants recruited from general practices (GPs) in two northern German cities received the AUDIT, which was embedded in a health-risk questionnaire. In total, 10,803 screenings were conducted. The retest reliability was tested on a subsample of 99 patients, with an intertest interval of 30 days. Sensitivity and specificity at a number of different cut-off values were estimated for the sample of alcohol consumers (n=8237). For this study, 1109 screen-positive patients received a diagnostic interview. Individuals who scored less than five points in the AUDIT and also tested negative in a second alcohol-related screen were defined as "negative" (n=6003). This definition was supported by diagnostic interviews of 99 screen-negative patients from which no false negatives could be detected. As the gold standard for detection of an alcohol-use disorder (AUD), we used the Munich-Composite International Diagnostic Interview (MCIDI), which is based on Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. RESULTS: On the item level, the reliability, measured by the intraclass correlation coefficient (ICC), ranged between .39 (Item 9) and .98 (Item 10). For the total score, the ICC was .95. For cut-off values of eight points and five points, 87.5% and 88.9%, respectively, of the AUDIT-positives, and 98.9% and 95.1%, respectively, of the AUDIT-negatives were identically identified at retest, with kappa = .86 and kappa = .81. At the cut-off value of five points, we determined good combinations of sensitivity and specificity for the following diagnoses: alcohol dependence (sensitivity and specificity of .97 and .88, respectively), AUD (.97 and .92), and AUD and/or at-risk consumption (.97 and .91). CONCLUSIONS: Embedded in a health-risk questionnaire in primary-care settings, the AUDIT is a reliable and valid screening instrument to identify at-risk drinkers and patients with an AUD. Our findings strongly suggest a lowering of the recommended cut-off value of eight points.     

The reliability and validity of the Alcohol,Smoking and Substance Involvement Screening Test (ASSIST) in first-episode psychosis

Aims

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is a brief, easily administered, valid and reliable screening instrument for all psychoactive substances in drug treatment and primary care settings. This study aims to determine the reliability and validity of the ASSIST for detecting substance use disorders in first-episode psychosis.

Participants

Participants were 214 first-episode psychosis patients attending the Early Psychosis Prevention and Intervention Centre (EPPIC) in Melbourne, Australia.

Measurements

Participants were administered the ASSIST, Alcohol Use Disorders Identification Test (AUDIT), the Severity of Dependence Scale (SDS) and the Brief Psychiatric Rating Scale (BPRS). Presence of DSM-IV substance abuse and dependence disorders in the previous 12 months was assessed using the Structured Clinical Interview for DSM-IV (SCID-IV).

Findings

The ASSIST total substance involvement (TSI) score and specific substance involvement (SSI) scores for cannabis, alcohol and amphetamine use demonstrated high levels of internal consistency and acceptable levels of concurrent and discriminative validity. Individuals with cutoff scores of ≥ 2, 4 and 1 on the ASSIST cannabis, alcohol and amphetamine SSI scores were 5 to 6 times more likely to meet the diagnostic criteria for these substance use disorders.

Conclusions

The ASSIST is a psychometrically sound measure of cannabis, alcohol and amphetamine use disorders in first-episode psychosis.     

Severity of alcohol problems and readiness to change alcohol use in primary care

Screening measures for hazardous alcohol use that are efficient and can provide clinically relevant information are essential for primary care providers (PCPs). This study examined the clinical utility of the Alcohol Use Disorders Identification Test (AUDIT) and the AUDIT-Consumption (AUDIT-C) as predictors of readiness to change alcohol use in a primary care setting. In total, 114 veterans completed the AUDIT, readiness to change ruler, and an alcohol use disorders diagnostic interview. Two AUDIT-C scores were obtained; one administered during a primary care visit and one derived from the AUDIT. The AUDIT, both AUDIT-C scores, and number of dependence symptoms significantly predicted readiness to change independent of demographic variables. The AUDIT accounted for the greatest percentage of variance in readiness to change (19%). The AUDIT provides information about alcohol severity and readiness to change, which could be clinically useful for providers identifying patients for brief alcohol interventions.
