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

Cannabis Use and Cannabis Use Disorder Among U.S. Adults with Psychiatric Disorders: 2001-2002 and 2012-2013

BACKGROUND

Rates of cannabis use disorder (CUD) have increased disproportionately among Veterans Administration (VA) patients with psychiatric disorders compared to patients with no disorder. However, VA patient samples are not representative of all U.S. adults, so results on disproportionate increases in CUD prevalence could have been biased. To address this concern, we investigated whether disproportionate increases in the prevalence of cannabis outcomes among those with psychiatric disorders would replicate in nationally representative samples of U.S. adults.

METHODS

Data came from two national surveys conducted in 2001-2002 (n = 43,093) and 2012-2013 (n = 36,309). Outcomes were any past-year non-medical cannabis use, frequent non-medical use (≥3 times weekly), and DSM-IV CUD. Psychiatric disorders included mood, anxiety and antisocial personality disorders. Logistic regression was used to generate predicted prevalences of the outcomes, prevalence differences calculated and additive interactions compared differences between those with and without psychiatric disorders.

RESULTS

Cannabis outcomes increased more among those with psychiatric disorders. The difference in prevalence differences included any past-year non-medical cannabis use, 2.45% (95%CI = 1.29-3.62); frequent non-medical cannabis use, 1.58% (95%CI = 0.83-2.33); CUD, 1.40% (95%CI = 0.58-2.21). For most specific disorders, prevalences increased more among those with the disorder.

CONCLUSIONS

In the U.S. general population, rates of cannabis use and CUD increased more among adults with psychiatric disorders than other adults, similar to findings from VA patient samples. Results suggest that although VA patients are not representative of all U.S. adults, findings from this important patient group can be informative. Greater clinical and policy attention to CUD is warranted for adults with psychiatric disorders.

Family history of substance problems among African Americans: Associations with drug use, drug use disorder, and prescription drug misuse

A family history of substance problems is a well-known risk factor for substance use and use disorders; however, much of this research has been conducted in studies with predominantly White subjects. The aim of this study was to examine the associations between family history density of substance problems and drug use, risk for drug use disorder, and prescription drug misuse in a sample of African American adults. Results indicate that family history density of substance problems increased the risk for all drug outcomes in the full sample. However, when subgroup analyses by gender were conducted, family history was not a risk factor among men for prescription drug misuse.

Subjective effects as predictors of substance use disorders in a clinical sample: A longitudinal study

BACKGROUND

The literature on the association between subjective effects (SEs; i.e., how an individual perceives their physiological and psychological reactions to a drug) and substance use disorders (SUDs) is largely limited to community samples. The present study addressed the following aims in a clinical sample: whether SEs predict general versus substance-specific SUD in adolescence and adulthood after controlling for conduct disorder symptoms (CDsymp); whether SEs predict SUDs across drug classes; whether SEs predict change in SUD from adolescence to adulthood; and whether there are racial/ethnic differences in associations.

METHODS

Longitudinal analyses were conducted using data from a sample of 744 clinical probands recruited from residential and outpatient SUD treatment facilities in CO during adolescence (Mage = 16.26) and re-assessed twice in adulthood (Mages = 22.56 and 28.96), approximately seven and twelve years after first assessment. SEs and CDsymp were assessed in adolescence. SUD severity was assessed at adolescence and twice during adulthood.

RESULTS

SEs assessed in adolescence robustly predicted general SUD for legal and illegal substances in adolescence and adulthood, whereas CDsymp predicted SUD primarily in adolescence. Higher positive and negative SEs in adolescence were associated with greater SUD severity after controlling for CDsymp, with similar magnitudes. Results indicated cross-substance effects of SEs on SUD. We found no evidence for racial/ethnic differences in associations.

CONCLUSIONS

We investigated the progression of SUD in a high-risk sample with greater odds of sustained SUD. In contrast to CDsymp, both positive and negative SEs consistently predicted general SUD across substances in adolescence and adulthood.

Prevalence of alcohol use disorders in primary health-care facilities in Russia in 2019

AIMS

To estimate prevalence of alcohol use disorders (AUD) and alcohol dependence (AD) for Russia in 2019, based on clients in primary health-care facilities.

DESIGN

Cross-sectional assessment of AUD and AD. Prevalence estimates were cross-validated using a treatment multiplier methodology.

SETTING

A total of 21 primary health-care facilities, including dispanserization units (population health preventive care settings).

PARTICIPANTS

A total of 2022 participants (986 women and 1036 men) 18 years of age and older.

MEASUREMENTS

Composite International Diagnostic Interview.

FINDINGS

The prevalence of AD and AUD was 7.0% [95% confidence interval (CI) = 5.9-8.1%] and 12.2% (95% CI = 10.8-13.6%), respectively. Marked sex differences were observed for the prevalence of AD (women: 2.8%; 95% CI = 1.7-3.8%; men: 12.2%; 95% CI = 10.3-14.1%) and AUD (women: 6.1%; 95% CI = 4.6-7.7%; men: 19.5%; 95% CI = 17.2-21.8%). Age patterns of AD and AUD prevalence were sex-specific. Among women, the prevalence of AUD and AD was highest in the youngest age group and decreased with age. Among men, the prevalence of AUD and AD was highest among men aged 45-59 years. Sensitivity analyses indicated that the prevalence of AD as estimated using a treatment multiplier (6.5%; 95% CI = 5.0-8.9%) was similar to the estimates of the main analysis.

CONCLUSIONS

Even though alcohol use has declined since 2003 in Russia, the prevalence of alcohol use disorders and alcohol dependence remains high at approximately 12 and 7%, respectively.

Adaptation of and Protocol for the Validation of the Alcohol Use Disorders Identification Test (AUDIT) in the Russian Federation for Use in Primary Healthcare

Aims

To adapt and validate the Alcohol Use Disorders Identification Test (AUDIT) for use in the Russian Federation and countries with Russian-speaking populations by:

Methods

Systematic review of past use and validation of the Russian-language AUDIT. Interviews to be conducted with experts to identify problems encountered in the use of existing Russian-language AUDIT versions. A pilot study using a revised translation of the Russian-language AUDIT that incorporates country-specific drinking patterns in the Russian Federation.

Results and Conclusions

The systematic review identified over 60 different Russian-language AUDIT versions without systematic validation studies. The main difficulties encountered with the use of the AUDIT in the Russian Federation were related to the lack of:

A revised version of the Russian-language AUDIT was created based on the pilot studies, and was validated in primary healthcare facilities in all regions in 2019/2020.

Validation of a screening test for alcohol use, the Russian Federation

OBJECTIVE

To validate a Russian-language version of the World Health Organization's Alcohol Use Disorders Identification Test (AUDIT).

METHODS

We invited 2173 patients from 21 rural and urban primary health-care centres in nine Russian regions to participate in the study (143 declined and eight were excluded). In a standardized interview, patients who had consumed alcohol in the past 12 months provided information on their sociodemographic characteristics and completed the Russian AUDIT, the Kessler Psychological Distress Scale and the Composite International Diagnostic Interview to identify problem drinking and alcohol use disorders. We assessed the feasibility of administering the test, its internal consistency and its ability to predict hazardous drinking and alcohol use disorders in primary health care in the Russian Federation.

FINDINGS

Of the 2022 patients included in the study, 1497 were current drinkers with Russian AUDIT scores. The test was internally consistent with good psychometric properties (Cronbach's α : 0.842) and accurately predicted alcohol use disorders and other outcomes (area under the curve > 75%). A three-item short form of the test correlated well with the full instrument and had similar predictive power (area under the curve > 80%). We determined sex-specific thresholds for all outcomes, as non-specific thresholds resulted in few women being identified.

CONCLUSION

With the validated Russian AUDIT, there is no longer a barrier to introducing screening and brief interventions into primary health care in the Russian Federation to supplement successful alcohol control policies.

Evaluating the Psychometric Properties of the Severson 7-Item Smokeless Tobacco Dependence Scale (SSTDS)

INTRODUCTION

The objective of the study was to assess the psychometric properties of the Severson 7-item Smokeless Tobacco Dependence Scale (SSTDS).

METHODS

Data from 95 male exclusive smokeless tobacco (ST) users were obtained through a self-administered mail survey to evaluate the reliability and validity of the SSTDS. Reliability of the scale was assessed by measures of internal consistency including Cronbach's coefficient alpha and item-total correlation. Other ST dependence scales and salivary cotinine concentration were used to evaluate concurrent validity. Structure model of the scale was ascertained by exploratory factor analysis. Overall accuracy and optimal cutoff score were obtained to evaluate SSTDS as a screening tool for ST dependence.

RESULTS

The SSTDS had high reliability as assessed by the internal consistency coefficient (ordinal α = 0.83). SSTDS total score was significantly correlated with Fagerström Test for Nicotine Dependence for ST users-FTND-ST (r = 0.42) and modified Tobacco Dependence Screener-TDS (r = 0.58). Exploratory factor analysis of the SSTDS identified two underlying factors measuring distinct dimensions of dependence. With reference to TDS based dependence diagnosis, SSTDS demonstrated good diagnostic accuracy (area under the curve: 0.82, 95% confidence interval: 0.74-0.90). Salivary cotinine concentration was not associated with the total score of the SSTDS; however, at an optimal cutoff score of SSTDS >9, everyday ST users classified as dependent had significantly higher cotinine concentration.

CONCLUSIONS

SSTDS is a reliable measure of dependence that has higher concurrent validity and reliability as compared with other commonly used ST dependence scales. Further research is needed using a larger and more diverse sample of ST users to unequivocally establish the validity of the scale.

IMPLICATIONS

ST dependence has multiple aspects that can be best studied by multidimensional dependence scales. The study findings validate that the SSTDS measures not only the physical dependence but also the behavioral and psychological dimensions of dependence. Good psychometric properties, diagnostic accuracy, and multidimensional structure of SSTDS indicate that it may serve as an effective tool in assessing ST dependence in clinical and research settings.

The World Health Organization Risk Drinking Levels Measure of Alcohol Consumption: Prevalence and Health Correlates in Nationally Representative Surveys of U.S. Adults, 2001-2002 and 2012-2013

OBJECTIVE

Little is known about change over time in the prevalence of World Health Organization (WHO) risk drinking levels (very high, high, moderate, low) and their association with health conditions, overall and by gender. The authors used two sets of nationally representative U.S. survey data to determine whether changes over time varied by gender and to examine whether health conditions related to alcohol were associated with WHO risk drinking level within each survey, and whether these associations differed by gender.

METHODS

Data on current drinkers from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; N=26,655) and the 2012-2013 NESARC-III (N=25,659) were analyzed using logistic regression. Prevalence differences between surveys were estimated for each drinking level overall and by gender. Within each survey, prevalence differences by WHO risk drinking level were estimated for alcohol use disorder (AUD), drug use disorders, functional impairment, liver disease, and depressive and anxiety disorders.

RESULTS

In the 2012-2013 survey, the prevalences of moderate, high, and very high risk drinking were 5.9%, 3.2%, and 3.5%, respectively, representing significant increases from the prevalences in the 2001-2002 survey, which were 1.0%, 0.6%, and 0.9%, respectively. The increase for very high risk drinking among men (0.5%) was smaller than the increase among women (1.4%). Within both surveys, compared with low risk, health conditions were significantly associated with very high risk (range of prevalence differences, 2.2%-57.8%), high risk (2.6%-41.3%), and moderate risk (0.6%-29.8%) drinking. Associations were similar by gender, except that there were stronger effects for AUD in men and for functional impairment and depressive and anxiety disorders in women.

CONCLUSIONS

The increase in potentially problematic drinking levels among U.S. adults emphasizes the need for better prevention and treatment strategies. The study results support the validity of the WHO risk drinking levels, which show clinical utility as nonabstinent drinking reduction treatment goals. Such goals could engage more people in treatment, improving public health by decreasing personal and societal consequences of risk drinking.

Gut microbiota dysbiosis is associated with worse emotional states in HIV infection

The biological mechanisms underlying emotional distress in HIV infection are likely to be complex but remain understudied. We investigated whether dysbiotic signatures in the gut microbiome of persons living with HIV (PLWH) are associated with their emotional status. We retrospectively examined the gut microbiome and clinical evaluation of 129 adults (94 PLWH and 35 HIV-) enrolled at UC San Diego's HIV Neurobehavioral Research Program. A subset of participants (32 PLWH vs. 13 HIV-) underwent an emotional assessment using the NIH Toolbox Emotion Battery summarized by three composite scores (negative affect, social satisfaction, and psychological well-being). We then sequenced the 16S rDNA V3-V4 regions from stool and performed taxonomic assignment using CLC Microbial Genomics Module. The gut microbiota profiles were evaluated in relation to participants' emotional assessment. All analyses were done in R statistical software. We found that the relative abundance of aerotolerant bacteria was significantly higher in PLWH (p < 0.01) and was associated with a lifetime major depression diagnosis independently of HIV status (p = 0.05). Moreover, PLWH experienced significantly worse psychological well-being (p = 0.02), less social satisfaction (p = 0.03), and more negative affect (p = 0.02). Higher levels of aerotolerant bacteria were associated with worse psychological well-being (rho = -0.35, p = 0.02), less social satisfaction (r = - 0.42, p < 0.01), and more negative affect (rho = 0.46, p < 0.01). The association of aerotolerant bacteria with social satisfaction and negative affect was independent of HIV status (p < 0.05, for both). The over-representation of aerotolerant bacteria in the gut may reflect worse oxidative stress and barrier defects and may contribute to emotional distress during HIV infection.

How to screen for at-risk alcohol use in transplant patients? From instrument selection to implementation of the AUDIT-C

BACKGROUND

Given that drinking >2-3 units of alcohol daily might already have adverse health effects, regular screening of at-risk drinking is warranted. We aimed to select and pilot a short instrument to accurately screen for at-risk drinking in transplant patients.

METHODOLOGY AND RESULTS

Five consecutive steps were completed: A comprehensive literature review identified 24 possible self-report instruments (step 1). These instruments were scored on six yes/no criteria (ie, length, concept measured, diagnostic accuracy, population, manual available, cost) (step 2). Four nurses piloted three instruments with the highest score and were interviewed on their experiences with using the AUDIT-C, TWEAK, and Five Shot. The AUDIT-C was the easiest to use and score, and items were clear. Cognitive debriefings with 16 patients were conducted to verify clarity of instructions and items, and suggestions were incorporated into a modified version of the AUDIT-C (step 4). A convenience sample of 130 Dutch-speaking heart transplant patients completed the modified AUDIT-C during a scheduled visit (Step 5), revealing that 27.6% of patients showed at-risk drinking.

CONCLUSION

The AUDIT-C might be a suitable instrument to identify at-risk drinking in routine post-transplant follow-up. Further validation, however, is indicated.

ICD-11/DSM-5: Entwicklungen und Änderungen bei Alkohol- und Substanzbezogenen Störungen

Die derzeitig gültigen ICD-10 Kriterien für alkohol- und substanzbezogene Abhängigkeit und schädlichen Gebrauch sind seit 1994 gültig. Ziel dieses Reviews ist es, die psychometrischen Eigenschaften Reliabilität der ICD-10 Diagnosen sowie einzelner Diagnosekriterien zu zeigen und ihre Konvergenz mit DSM-IV Diagnosen abzugleichen. Darüber hinaus werden die Hintergründe für die Entwicklung von ICD-11 und DSM-5 präsentiert und die Konvergenz zwischen diesen Diagnosesystemen (DSM-IV/5 mit ICD-10/11) berichtet. Die Vor- und Nachteile der Entwicklung von ICD- und DSM-Konzepten und deren Konvergenz werden kritisch diskutiert.

Illicit drug use by mothers and their daughters in Australia: A comparison of two generations

BACKGROUND

While recent decades have witnessed an increase in the use of illicit drugs in Australia, the extent to which the types of drugs used has changed over a generation of young women has not been documented.

METHODS

Data are from a prospective birth cohort study. Mothers were recruited in early pregnancy (1981-83) and then they and their child were followed up, with mothers interviewed 27 years (2008-2011), and daughters 30 years (2010-14), after the birth. At these most recent interviews both mothers and daughters were administered the Composite International Diagnostic Interview (CIDI III). Comparisons are for mothers and daughters separated by a 25 year period. For this study, we compare levels of lifetime use of a range of illicit drugs and drug use disorders reported by mothers and their daughters (N = 998 mother/daughter pairs) with adjustment for family income, marital status, education and occupation.

RESULTS

There has been a generational increase in the use of illicit substances and prevalence of substance use disorders experienced by Australian women. Mothers' use of illicit drugs was generally restricted to cannabis. By contrast the majority of daughters report lifetime use of an illicit drug with cannabis, club drugs and stimulants the most common. Compared to the mothers, daughters used club drugs 50 times, cocaine 19 times and inhalants 20 times more often. Daughters report experiencing 12 times the rate of cocaine use disorders, 9 times the rate of stimulant disorders and 7 times the rate of cannabis use disorders compared to their mothers.

CONCLUSIONS

Mothers of the current generation of 30 year old Australian women rarely used illicit drugs and few experienced a drug use disorder. The current generation of young women report commonly using one or more illicit drugs with a substantial minority experiencing a drug use disorder. It is unlikely that the use of illicit drugs by young women in Australia will be reversed in the foreseeable future. Government policies and treatment practices need to be calibrated to the reality of the much greater contact with illicit drugs being exhibited by younger women.

Alcohol use and its consequences in the Czech Republic

OBJECTIVE

Alcohol consumption is associated with substantial public health burden. This article summarises available information on the patterns and prevalence of alcohol use in the Czech Republic with a focus on the heavy alcohol use and its health and social consequences.

METHODS

A non-systematic literature review was conducted. The data sources included primarily 3 series of surveys in the adult population, 2 series of surveys in the school population, routine monitoring system of per capita alcohol consumption, routine statistics on alcohol-related morbidity and mortality, and alcohol-related crime.

RESULTS

In recent years the registered alcohol consumption in the Czech Republic has been very high; 9.8 litres of pure alcohol were consumed per capita in 2017. Recently, the prevalence of hazardous alcohol consumption in the adult population has reached 16.8-17.6% and harmful alcohol consumption 9.0-9.3%. From 12% to 17% of adult population and 12% of adolescent population were heavy episodic drinkers. Alcohol-related disorders are disproportionately higher (2-3 times) among men. Mortality for alcohol-related causes fully attributable to alcohol (AAF = 100%) and their proportion in overall mortality is on increase.

CONCLUSIONS

Alcohol consumption as well as the prevalence of heavy episodic drinking in the Czech Republic belongs among the highest globally. On the other hand, declines in alcohol use have been recently observed among children and adolescents. Available data on alcohol-related morbidity indicate stable situation, though alcohol-related mortality is increasing. Alcohol-related burden is rather underestimated and evidence-based alcohol policy should be increasingly implemented.

Chronic childhood adversity and speed of transition through stages of alcohol involvement

BACKGROUND

While research suggests that chronic childhood adversities may be predictors of alcohol use disorders, little is known of their influence on accelerated transitions through stages of alcohol involvement. We estimated the speed of transition from first opportunity (to first drink, regular drinking) to alcohol use disorder, by type and number of childhood adversities experienced.

METHODS

Nine-hundred-and-fifteen individuals participated in the Mexican Adolescent Mental Health Survey (a stratified multistage probabilistic sample), first as adolescents (12-17 years of age) and again eight years later as young adults (19-26 years of age). The WHO World Mental Health Composite International Diagnostic Interview (WMH-CIDI) assessed DSM-IV alcohol use disorders and twelve chronic childhood adversities. We calculated random coefficient models to estimate the association of childhood adversities with speed through stages of alcohol use involvement.

RESULTS

Mean time from opportunity to disorder was 4.08 years and the average growth rate was 1.36 years between each stage of involvement. Some, but not all, childhood adversities accelerated the growth rate, decreasing latency between each stage of alcohol use involvement from 1.36 to 0.93 years for witnessing family violence, 0.87 years for having a life-threatening illness, 0.79 years for sexual abuse to 0.77 years for physical abuse (p < 0.01).

CONCLUSIONS

There is a narrower window of opportunity to prevent progression through stages of alcohol involvement in youth who have experienced certain childhood adversities. Our findings are consistent with the dimensional approach of childhood adversity that distinguishes between experiences of threat and deprivation that might differentially influence neurological development.

Gender differences in exposure to potentially traumatic events and diagnosis of posttraumatic stress disorder (PTSD) by racial and ethnic group

OBJECTIVE

There is a robust literature base documenting gender differences and racial/ethnic differences in exposure to potentially traumatic events (PTEs) and posttraumatic stress disorder (PTSD) diagnosis. Yet, to the best of our knowledge, this is the first study to evaluate the risk of PTEs and PTSD between genders, stratified by race/ethnicity. We aimed to better understand whether factors associated with poor psychological adjustment following PTEs (e.g., PTE type, sociodemographic factors, social support) varied by gender and race/ethnicity.

METHOD

Data were collected from three U.S.-based national studies comprising the Collaborative Psychiatric Epidemiologic Surveys (CPES; N = 13,649). Trained lay interviewers administered questionnaires and collected data on PTE exposure, PTSD, and psychosocial covariates. Regression analyses were conducted to investigate relations between PTEs, PTSD, and gender, stratified by race/ethnicity.

RESULTS

Adjusting for sociodemographic variables, mental health comorbidity, social support, and PTE frequency, White, African-American, and Afro-Caribbean women had higher odds of PTSD than men in their respective racial/ethnic groups, whereas gender differences were not observed for Latinos or Asians.

CONCLUSION

Findings suggest that risk of exposure to PTEs and PTSD may differ by gender and race/ethnicity. Future studies should consider the contributions of social, cultural, and contextual factors in estimating PTSD risk.

Exploring the Potential of Savings-Led Economic Strengthening HIV Interventions Among High-Risk Economically Vulnerable Fishing Communities in Uganda: Associations Between Use of Commitment Savings, Sexual Risk Behavior, and Problematic Alcohol Use

Fishing communities are a most-at-risk population for HIV in Uganda. Alcohol use and abuse and economic vulnerability fuel risky sexual practices and lead to increased risk of HIV infection in these communities. Economic strengthening is an emerging intervention approach and interventions promoting saving money via mechanisms with a "soft commitment" in the form of restricting or charging small fees for withdrawals, may serve to reduce spending on alcohol and spending that leads to HIV risk behaviors in cash-based economies. However, little research has been conducted to explore the potential for commitment savings-led economic strengthening interventions to address alcohol use and sexual risk behavior among fisherfolk. This cross-sectional study explored the associations between commitment savings, HIV sexual risk behavior, and problematic alcohol among fisherfolk. We also determined whether commitment savings moderated the associations between problematic alcohol use and risky sexual behaviors. 300 (132 male, 168 female) residents of fishing communities on Lake Victoria, Uganda completed a structured interviewer-assisted interview. Over half (55.3%) used commitment savings by saving money in a bank or savings cooperative or via mobile money. Having problematic alcohol use increased the rate of risky unprotected sex with: all partners (adjIRR 6.08, 95% CI 4.30-8.60) and with casual partners and CSWs/clients (adjIRR 4.90, 95% CI 3.09-7.78), and increased the odds of having met a sex partner at an alcohol venue (adjOR 2.84, 95% CI 1.46-5.51) compared to those without problematic alcohol use. Commitment savings was associated with lower odds of: problematic alcohol use (adjOR 0.50, 95% CI 0.26-0.96), meeting a sex partner at an alcohol venue (adjOR 0.43, 95% CI 0.24-0.78), as well as lower rates of risky unprotected sex with all partners (adjIRR 0.68, 95% CI 0.48-0.96), and with causal partners, CSWs/clients (adjIRR 0.38, 95% CI 0.17-0.85). Use of commitment savings moderated the associations between problematic alcohol use and unprotected sex. However, the moderating effects of commitment savings varied by gender. These findings suggest that promoting saving money in savings mechanisms which involve a commitment may be a potentially viable avenue for HIV prevention among fishing communities and may be particularly helpful for those who have problematic alcohol use.

Time trends in US cannabis use and cannabis use disorders overall and by sociodemographic subgroups: a narrative review and new findings

Background: Due to significant comorbidity and impairment associated with cannabis use and cannabis use disorder, understanding time trends in cannabis use and cannabis use disorder is an important public health priority.Objectives: To identify trends in cannabis use and cannabis use disorder overall, and by sociodemographic subgroup.Methods: Narrative review of published findings on trends in cannabis use and cannabis use disorders in data from repeated cross-sectional US general population surveys. In addition, in National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2002-2002) and NESARC-III (2012-2013) data, logistic regression was used to examine whether trends differed between subgroups of adults.Results: The review showed that in adults, cannabis use increased over the past decade overall and within sociodemographic subgroups (gender, age, race/ethnicity, income, education, marital status, urbanicity, region, pregnancy status, disability status), with greater increases in men and disabled adults. Most sources also indicated significant increases in cannabis use disorders. New analysis showed significantly greater increases in adult cannabis use and cannabis use disorder in men (p ≤ .0001); young adults (p < .05); Blacks (vs. Whites, p < .01); low income groups (p < .001); never-married p ≤ .0001), and urban residents (p < .05). In adolescents, cannabis use generally decreased, although recent increases were observed in older and non-White adolescents.Conclusion: Cannabis use and cannabis use disorder are increasing in adults, with specific sociodemographic groups at higher risk, and may be increasing in some adolescent subgroups. Studies should determine mechanisms for differential trends to provide information to policymakers and enable informed decisions on cannabis legalization and service planning.

Childhood maltreatment and alcohol use in young adulthood: the role of self-regulation processes

INTRODUCTION

Childhood maltreatment has been linked to later alcohol use and disorders. Few studies have examined the pathways linking child maltreatment to alcohol use during the transition to adulthood. Currently, minimal understanding of such developmental pathways limits the success of alcohol prevention and intervention efforts for this highly vulnerable population. The present study examined if individual differences in self-regulation processes are critical factors that mediate the association between childhood maltreatment and risk for alcohol use.

METHOD

Young adults (N = 335; mean age = 21.7), who were recruited from the community, completed self-report measures of childhood maltreatment, different facets of self-regulation processes, and alcohol use. Multiple structural equation modeling (SEM) analyses were performed to specify the roles of two related, but different, self-regulation processes (i.e., behavioral self-control and behavioral dysregulation) in linking child maltreatment to four different patterns of drinking behaviors, including drinking frequency, binge drinking, alcohol-related problems, and alcohol dependence. Common risk factors for alcohol use, such as psychological symptoms and peer alcohol use, were also entered into the models.

RESULTS

We found that behavioral dysregulation particularly plays a mediating role in the associations between childhood emotional abuse and problematic alcohol use during young adulthood.

CONCLUSION

The results of this research suggest that self-control processes would be potentially useful targets to prevent problematic alcohol use among young people who have had exposure to childhood maltreatment.

The 10-year functional outcome of schizophrenia in Butajira, Ethiopia

BACKGROUND

Long-term functional schizophrenia outcomes are not well characterized in low-income environments because of the rarity of prospective studies.

OBJECTIVES

To assess and describe long-term schizophrenia's functional outcomes and potential outcome predictors.

METHODS

Following a baseline assessment, 316 people with schizophrenia were studied for 10 years, on average. Of the total, 79 were incident cases: cases with onset of the illness occurring two years or less from entry into the study. SF-36 scores of physical and social functioning were used to assess functional outcomes. Linear mixed models were employed to evaluate the association of functioning with potential predictors.

RESULTS

Social and physical functioning scores regarding the cohort were lower than the population's norm for most of the follow-up period. Incident cases had better function than prevalent cases. Fifteen percent of incident and 30% of prevalent cases had reduced social functioning for at least six years. Declining symptom severity during the follow-up period was significantly associated with improvement in social functioning. When baseline functioning was controlled for, the long-term trend in functionality was not associated with demographic or illness characteristics (age and speed of onset, duration of illness and neuroleptic use at entry, substance use, and medication adherence).

CONCLUSION

Long-term physical and social functioning of the population with schizophrenia were significantly lower than the population norm. A significant proportion of the cohort had lower functioning for the long-term. Functioning was not associated with demographic or illness characteristics of the study population.

When should the driver with a history of substance misuse be allowed to return to the wheel? A review of the substance misuse section of the Australian national guidelines

Assessing fitness to drive in applicants with a historical or current substance use disorder presents a specific clinical challenge. The Australian guidelines require evidence of remission and absence of cognitive change when considering applications for re-licensing driver or individuals applying to reengage in safety-sensitive work. This paper reviews some of the clinical and biochemical indicators that determine whether a particular person is in 'remission' and meets the criteria for return to driving or other safety-sensitive occupation. It provides an overview of the challenges in establishing an evidence-based approach to determining fitness for safety critical activities. There is no internationally accepted definition of 'remission'. Review of the literature and examination of assessment protocols from other national jurisdictions are available for alcohol and the more important drugs of interest in road safety. Assessing fitness to drive when there is a history of substance misuse and/or substance use disorders is a complex issue that requires assessment of biomarkers, clinical findings and clinical assessment before the person returns to driving. We propose that hair testing provides a reliable and reproducible way to demonstrate remission and provide cost-effective monitoring. Standardised psychological tests could provide a reproducible assessment of the cognitive effects of drug use and suitability to resume driving. We recommend that AustRoads amend the national guidelines to reflect an evidence-based approach to assessing fitness to drive after conviction for offences related to alcohol and drug use.

Profiles of childhood trauma and psychopathology: US National Epidemiologic Survey

PURPOSE

Childhood trauma may increase vulnerability to numerous specific psychiatric disorders, or a generalised liability to experience dimensions of internalising or externalising psychopathology. We use a nationally representative sample (N = 34,653) to examine the long-term consequences of childhood trauma and their combined effect as predictors of subsequent psychopathology.

METHODS

Data from the US National Epidemiologic Survey on Alcohol and Related Conditions were used. Latent class analysis was used to identify childhood trauma profiles and multinomial logistic regression to validate and explore these profiles with a range of associated demographic and household characteristics. We used Structural Equation Modelling to substantiate initial latent class analysis findings by investigating a range of mental health diagnoses. Internalising and externalising domains of psychopathology were regressed on trauma profiles and associated demographic and household characteristics. We used Differential Item Functioning to examine associations between the trauma groups and a number of psychiatric disorders within internalising and externalising dimensions of mental health.

RESULTS

We found a 3-class model of childhood trauma in which 85% of participants were allocated to a low trauma class; 6% to a multi-type victimization class (reporting exposures for all the child maltreatment criteria); and 9% to a situational trauma class (exposed to a range of traumas). Confirmatory Factor Analysis revealed an internalising-externalising spectrum was used to represent lifetime reporting patterns of mental health disorders. Both trauma groups showed specific gender and race/ethnicity differences, related family discord and increased psychopathology. Additionally, we found significant associations between the trauma groups and specific diagnoses within the internalising-externalising spectrum of mental health.

CONCLUSIONS

The underlying patterns in the exposure to types of interpersonal and non-interpersonal traumas and associated mental health highlight the need to screen for particular types of childhood traumas when individuals present with symptoms of psychiatric disorders.

Hazardous alcohol consumption and alcohol-related problems are associated with unknown and HIV-positive status in fishing communities in Uganda

In Uganda, alcohol consumption is associated with higher HIV prevalence. However, research is needed to better understand how different patterns of alcohol consumption and alcohol-related problems may drive this association. In this cross-sectional study, we examined how hazardous alcohol use and alcohol-related problems such as psychological, physical, and social harms are associated with HIV status in fishing communities in Uganda. 300 (132 male, 168 female) residents of fishing communities in Uganda (75 participants from each of the following occupational groups: fishmongers, alcohol sellers, commercial sex workers (CSW), and fishermen) completed an interviewer-assisted computerized interview. We captured information on sociodemographics and HIV testing history. Prior 12-month hazardous alcohol consumption patterns and alcohol-related problems were assessed with the AUDIT and AUDADIS. 19.7%, 58.0%, and 23.3% of the sample reported being HIV positive, being HIV negative from a test within the prior 12 months, and not knowing their HIV status respectively. 18.7% reported the co-occurrence of hazardous alcohol consumption patterns and alcohol-related problems. 7.7% reported either hazardous alcohol consumption patterns or alcohol-related problems. Compared to non-drinkers, those with co-occurring hazardous consumption and alcohol-related problems had greater odds of being HIV positive (adjOR 2.75, 95% CI 1.17-6.43) and of unknown HIV status (adjOR 3.35, 95% CI 1.52-7.42). Reporting only hazardous consumption levels, only alcohol-related problems, or low-risk drinking, did not increase the odds of being HIV positive or of unknown status. Among those not HIV positive, those with co-occurring hazardous consumption and alcohol-related problems had greater odds of never having had an HIV test (adjOR 3.78, 95% CI 1.63-8.68). The co-occurrence of hazardous alcohol use and alcohol related problems appears to be a prominent risk factor for HIV infection, not knowing one's HIV status, and never testing for HIV in this setting.

Magnetic resonance cholangiogram patterns and clinical profiles of ketamine-related cholangiopathy in drug users

BACKGROUND & AIMS

Recreational ketamine use has emerged as an important health and social issue worldwide. Although ketamine is associated with biliary tract damage, the clinical and radiological profiles of ketamine-related cholangiopathy have not been well described.

METHODS

Chinese individuals who had used ketamine recreationally at least twice per month for six months in the previous two years via a territory-wide community network of charitable organizations tackling substance abuse were recruited. Magnetic resonance cholangiography (MRC) was performed, and the findings were interpreted independently by two radiologists, with the findings analysed in association with clinical characteristics.

RESULTS

Among the 343 ketamine users referred, 257 (74.9%) were recruited. The mean age and ketamine exposure duration were 28.7 (±5.8) and 10.5 (±3.7) years, respectively. A total of 159 (61.9%) had biliary tract anomalies on MRC, categorized as diffuse extrahepatic dilatation (n = 73), fusiform extrahepatic dilatation (n = 64), and intrahepatic ductal changes (n = 22) with no extrahepatic involvement. Serum alkaline phosphatase (ALP) level (odds ratio [OR] 1.007; 95% CI 1.002-1.102), lack of concomitant recreational drug use (OR 1.99; 95% CI 1.11-3.58), and prior emergency attendance for urinary symptoms (OR 1.95; 95% CI 1.03-3.70) had high predictive values for biliary anomalies on MRC. Among sole ketamine users, ALP level had an AUC of 0.800 in predicting biliary anomalies, with an optimal level of ≥113 U/L having a positive predictive value of 85.4%. Cholangiographic anomalies were reversible after ketamine abstinence, whereas decompensated cirrhosis and death were possible after prolonged exposure.

CONCLUSIONS

We have identified distinctive MRC patterns in a large cohort of ketamine users. ALP level and lack of concomitant drug use predicted biliary anomalies, which were reversible after abstinence. The study findings may aid public health efforts in combating the growing epidemic of ketamine abuse.

LAY SUMMARY

Recreational inhalation of ketamine is currently an important substance abuse issue worldwide, and can result in anomalies of the biliary system as demonstrated by magnetic resonance imaging. Although prolonged exposure may lead to further clinical deterioration, such biliary system anomalies might be reversible after ketamine abstinence. Clinical trial number: NCT02165488.

Patterns of adverse childhood experiences and substance use among young adults: A latent class analysis

INTRODUCTION

Adverse childhood experiences (ACEs) have been strongly linked with subsequent substance use. The aim of this study was to investigate how different patterns of ACEs influence substance use in young adulthood.

METHODS

Using a community sample of young individuals (N=336; ages 18-25), we performed latent class analyses (LCA) to identify homogenous groups of young people with similar patterns of ACEs. Exposure to ACEs incorporates 13 childhood adversities including childhood maltreatment, household dysfunction, and community violence. Multiple linear and logistic regression models were used in an effort to examine the associations between ACEs classes and four young adult outcomes such as alcohol-related problems, current tobacco use, drug dependence symptoms, and psychological distress.

RESULTS

LCA identified four heterogeneous classes of young people distinguished by different patterns of ACEs exposure: Low ACEs (56%), Household Dysfunction/Community Violence (14%), Emotional ACEs (14%), and High/Multiple ACEs (16%). Multiple regression analyses found that compared to those in the Low ACEs class, young adults in the High/Multiple ACEs class reported more alcohol-related problems, current tobacco use, and psychological symptoms, controlling for sociodemographic characteristics and common risk factors for substance use such as peer substance use.

CONCLUSIONS

Our findings confirm that for many young people, ACEs occur as multiple rather than single experiences. The results of this research suggest that exposure to poly-victimization during childhood is particularly related to substance use during young adulthood.

Drivers with alcohol use disorders and their risks of crash involvement

BACKGROUND

The relationship between driver blood alcohol concentration (BAC) and crash involvement is well understood. However, the role of alcohol use disorders (AUDs) (i.e., dependence or abuse) in crash occurrence, as distinguished from non-clinical heavy alcohol consumption, has not been adequately explored.

METHODS

Data from the 2010-2011 Crash Risk Study conducted in Virginia Beach, VA, were used in this study. Drivers involved in crashes were compared with control drivers, and four drinker groups were examined: alcohol dependent, alcohol abusers, heavy drinkers, and all other current (i.e., normative) drinkers. Logistic regression analyses were conducted on two outcomes: having a moderate BAC (≥0.05 g/dl), and crash involvement.

RESULTS

Overall, 2411 crash-involved and 5514 control drivers provided useable data, 52.4% of which were men and 70.8% Whites. The prevalence of drivers with AUDs was lower for the crash-involved drivers (8.7%) than for the control drivers (12.7%). Only heavy drinkers, but not abusive or dependent drinkers, were over four times more likely to drive with moderate BACs at nighttime. More important, at nighttime, the odds of crash involvement for dependent drinkers were only one third of those for normative drinkers. Daytime crashes, however, were more likely to involve normative drinkers than any of the other three drinker types.

CONCLUSIONS

Drivers with AUDs are not more likely than normative drinkers to drive with moderate BACs at night. After accounting for the influence of BAC, dependent drinkers have a lower risk of being involved in a crash, at any time of the day.

US Epidemiology of Cannabis Use and Associated Problems

This review provides an overview of the changing US epidemiology of cannabis use and associated problems. Adults and adolescents increasingly view cannabis as harmless, and some can use cannabis without harm. However, potential problems include harms from prenatal exposure and unintentional childhood exposure; decline in educational or occupational functioning after early adolescent use, and in adulthood, impaired driving and vehicle crashes; cannabis use disorders (CUD), cannabis withdrawal, and psychiatric comorbidity. Evidence suggests national increases in cannabis potency, prenatal and unintentional childhood exposure; and in adults, increased use, CUD, cannabis-related emergency room visits, and fatal vehicle crashes. Twenty-nine states have medical marijuana laws (MMLs) and of these, 8 have recreational marijuana laws (RMLs). Many studies indicate that MMLs or their specific provisions did not increase adolescent cannabis use. However, the more limited literature suggests that MMLs have led to increased cannabis potency, unintentional childhood exposures, adult cannabis use, and adult CUD. Ecological-level studies suggest that MMLs have led to substitution of cannabis for opioids, and also possibly for psychiatric medications. Much remains to be determined about cannabis trends and the role of MMLs and RMLs in these trends. The public, health professionals, and policy makers would benefit from education about the risks of cannabis use, the increases in such risks, and the role of marijuana laws in these increases.

Trauma exposure, incident psychiatric disorders, and disorder transitions in a longitudinal population representative sample

Heterotypic continuity, whereby individuals transition from one disorder to another, is common; however, longitudinal studies examining transdiagnostic predictors of heterotypic continuity are lacking. The current study examined whether trauma exposure during childhood (maltreatment) and adulthood (interpersonal and non-interpersonal trauma) is associated with heterotypic continuity in a national sample. Men and women (N = 34,653) who participated in Waves 1 (2001-2002) and 2 (2004-2005) of the National Survey of Alcohol and Related Conditions (NESARC) completed face-to-face interviews about trauma exposure and psychopathology. Risk ratios and population attributable risk proportions (PARPs) quantified the effects of childhood maltreatment and interpersonal and non-interpersonal trauma exposure between Waves 1 and 2 on risk for incident disorders and transitions between specific types of disorders. Twenty percent of respondents reported a Wave 2 incident disorder. Those with any Wave 1 disorder were at increased risk of incident mood (RR range = 1.2-2.1) and anxiety (RR = 1.5-2.7) disorders at Wave 2. Child maltreatment and interpersonal trauma exposure since Wave 1 were associated with roughly 50% of the risk for disorder transitions (RR range = 1.2-2.7); non-interpersonal trauma was associated with 30% of the risk for disorder transitions (RR range = 1.0-1.7). Findings suggest that new onset disorders were common in U.S. adults and trauma exposure explained a large proportion of disorder incidence as well as progression from one disorder to another. Universal prevention efforts that begin early in life, rather than those targeted at specific disorders, would be fruitful for reducing the burden of population mental health and preventing a cascade of mental disorders over the life course.

US Adult Illicit Cannabis Use, Cannabis Use Disorder, and Medical Marijuana Laws: 1991-1992 to 2012-2013

Importance

Over the last 25 years, illicit cannabis use and cannabis use disorders have increased among US adults, and 28 states have passed medical marijuana laws (MML). Little is known about MML and adult illicit cannabis use or cannabis use disorders considered over time.

Objective

To present national data on state MML and degree of change in the prevalence of cannabis use and disorders.

Design, Participants, and Setting

Differences in the degree of change between those living in MML states and other states were examined using 3 cross-sectional US adult surveys: the National Longitudinal Alcohol Epidemiologic Survey (NLAES; 1991-1992), the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; 2001-2002), and the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III; 2012-2013). Early-MML states passed MML between NLAES and NESARC ("earlier period"). Late-MML states passed MML between NESARC and NESARC-III ("later period").

Main Outcomes and Measures

Past-year illicit cannabis use and DSM-IV cannabis use disorder.

Results

Overall, from 1991-1992 to 2012-2013, illicit cannabis use increased significantly more in states that passed MML than in other states (1.4-percentage point more; SE, 0.5; P = .004), as did cannabis use disorders (0.7-percentage point more; SE, 0.3; P = .03). In the earlier period, illicit cannabis use and disorders decreased similarly in non-MML states and in California (where prevalence was much higher to start with). In contrast, in remaining early-MML states, the prevalence of use and disorders increased. Remaining early-MML and non-MML states differed significantly for use (by 2.5 percentage points; SE, 0.9; P = .004) and disorder (1.1 percentage points; SE, 0.5; P = .02). In the later period, illicit use increased by the following percentage points: never-MML states, 3.5 (SE, 0.5); California, 5.3 (SE, 1.0); Colorado, 7.0 (SE, 1.6); other early-MML states, 2.6 (SE, 0.9); and late-MML states, 5.1 (SE, 0.8). Compared with never-MML states, increases in use were significantly greater in late-MML states (1.6-percentage point more; SE, 0.6; P = .01), California (1.8-percentage point more; SE, 0.9; P = .04), and Colorado (3.5-percentage point more; SE, 1.5; P = .03). Increases in cannabis use disorder, which was less prevalent, were smaller but followed similar patterns descriptively, with change greater than never-MML states in California (1.0-percentage point more; SE, 0.5; P = .06) and Colorado (1.6-percentage point more; SE, 0.8; P = .04).

Conclusions and Relevance

Medical marijuana laws appear to have contributed to increased prevalence of illicit cannabis use and cannabis use disorders. State-specific policy changes may also have played a role. While medical marijuana may help some, cannabis-related health consequences associated with changes in state marijuana laws should receive consideration by health care professionals and the public.

Changes in US Lifetime Heroin Use and Heroin Use Disorder: Prevalence From the 2001-2002 to 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions

Importance

Heroin use is an urgent concern in the United States. Little is know about the course of heroin use, heroin use disorder, and associated factors.

Objective

To examine changes in the lifetime prevalence, patterns, and associated demographics of heroin use and use disorder from 2001-2002 to 2012-2013 in 2 nationally representative samples of the US adult general population.

Design, Setting, and Participants

This survey study included data from 43 093 respondents of the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and 36 309 respondents of the 2012-2013 NESARC-III. Data were analyzed from February 2 to September 15, 2016.

Main Outcomes and Measures

Lifetime heroin use and DSM-IV heroin use disorder.

Results

Among the 79 402 respondents (43.3% men; 56.7% women; mean [SD] age, 46.1 [17.9] years), prevalence of heroin use and heroin use disorder significantly increased from 2001-2002 to 2012-2013 (use: 0.33% [SE, 0.03%] vs 1.6% [SE, 0.08%]; disorder: 0.21% [SE, 0.03%] vs 0.69% [SE, 0.06%]; P < .001). The increase in the prevalence of heroin use was significantly pronounced among white (0.34% [SE, 0.04%] in 2001-2002 vs 1.90% [SE, 0.12%] in 2012-2013) compared with nonwhite (0.32% [SE, 0.05%] in 2001-2002 vs 1.05% [SE, 0.10%] in 2012-2013; P < .001) individuals. The increase in the prevalence of heroin use disorder was more pronounced among white individuals (0.19% [SE, 0.03%] in 2001-2002 vs 0.82% [SE, 0.08%] in 2012-2013; P < .001) and those aged 18 to 29 (0.21% [SE, 0.06%] in 2001-2002 vs 1.0% [0.17%] in 2012-2013; P = .01) and 30 to 44 (0.20% [SE, 0.04%] in 2001-2002 vs 0.77% [0.10%] in 2012-2013; P = .03) years than among nonwhite individuals (0.25% [SE, 0.04%] in 2001-2002 vs 0.43% [0.07%] in 2012-2013) and older adults (0.22% [SE, 0.04%] in 2001-2002 vs 0.51% [SE, 0.07%] in 2012-2013). Among users, significant differences were found across time in the proportion of respondents meeting DSM-IV heroin use disorder criteria (63.35% [SE, 4.79%] in 2001-2001 vs 42.69% [SE, 2.87%] in 2012-2013; P < .001). DSM-IV heroin abuse was significantly more prevalent among users in 2001-2002 (37.02% [SE, 4.67%]) than in 2012-2013 (19.19% [SE, 2.34%]; P = .001). DSM-IV heroin dependence among users was similar in 2001-2002 (28.22% [SE, 3.95%]) and in 2012-2013 (25.02% [SE, 2.20%]; P = .48). The proportion of those reporting initiation of nonmedical use of prescription opioids before initiating heroin use increased across time among white individuals (35.83% [SE, 6.03%] in 2001-2002 to 52.83% [SE, 2.88%] in 2012-2013; P = .01).

Conclusions and Relevance

The prevalence of heroin use and heroin use disorder increased significantly, with greater increases among white individuals. The nonmedical use of prescription opioids preceding heroin use increased among white individuals, supporting a link between the prescription opioid epidemic and heroin use in this population. Findings highlight the need for educational campaigns regarding harms related to heroin use and the need to expand access to treatment in populations at increased risk for heroin use and heroin use disorder.

Gender Differences in Substance Use, Problems, Social Situation and Treatment Experiences among Clients Entering Addiction Treatment in Stockholm

AIM

While gender differences in substance use/problems have been found to be smaller in more gender-equal countries such as Sweden, gender-specific norms still prevail, and women's (mis)use continues to be more condemned than men's. This article analyses and discusses similarities and differences between the sexes in alcohol and drug treatment in terms of men's and women's treatment experiences, consumption/problems, social situation, and life-domain problems.

METHOD

1865 respondents were interviewed (structured interview) at the beginning of a new treatment episode in 2000–2002 in Stockholm County (sample representative of those starting a new treatment episode for alcohol or drug problems in Stockholm County). Responses are cross-tabulated by sex and multivariate logistic regression is used to predict whether men or women have more severe problems in various life domains of the Addiction Severity Index (ASI composite scores).

Results

Bivariate analyses showed that women and men differ significantly in their treatment experiences. Women are more likely to have contact with mental health services, whereas men tend to deal more with the criminal justice system. The sexes do not differ in alcohol and drug problem severity, but women are more likely to have problems with pharmaceuticals. In contrast to the hypothesis, it turned out that men, not women, are more marginalised as concerns housing, income, family situation, lack of friends. Women report more problems related to family, social life and mental/physical health, while men report higher criminality and financial problems.

Conclusions

There are no gender differences among the clients in the treatment system when it comes to substance problem severity but differences occur concerning the clients’ social situation and different life-domain problems. As men are more socially exposed a focus on women may obscure problems among men.

Toward National Estimates of Effectiveness of Treatment for Substance Use

OBJECTIVE

To estimate how results would have varied if a substance abuse clinical trial had been conducted with nationally representative adults with substance use and with representative adults receiving substance use treatment.

METHODS

Results were analyzed from a multisite clinical trial comparing the effectiveness of the Therapeutic Education System to treatment as usual for outpatient addiction treatment (n = 507). Patients were recruited between June 2010 and August 2011. Abstinence was the primary outcome. The general population sample and general population-treated samples were derived from Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) (n = 43,093). Propensity scores provided a standardized measure of the difference between clinical trial participants and the 2 NESARC samples. The clinical trial was reanalyzed by reweighting the sample with propensity scores derived from the 2 samples to obtain generalizable estimates of treatment effects.

RESULTS

Before the clinical trial sample was reweighted, the odds ratio (OR) of response to Therapeutic Education System versus treatment as usual in the trial was 1.62 (95% CI, 1.12-2.35). After the sample was reweighted to be representative of the 2 NESARC groups, ORs were 1.33 (95% CI, 0.34-5.26) for the representative sample with any substance use and 1.64 (95% CI, 0.82-3.27) for the representative treated sample.

CONCLUSIONS

Applying propensity score weighting to clinical trial results provides a method for estimating the population generalizability of clinical trial findings that relies on effect moderators observed in the study sample and population. Broader confidence intervals in the reweighted samples do not necessarily indicate lack of efficacy of the Therapeutic Education System but rather greater uncertainty concerning effectiveness in general population samples.

Exploration of Core Symptoms for the Diagnosis of Alcohol Dependence in the ICD-10

BACKGROUND

The classification of alcohol use disorder has changed over the past century. Now, the conceptualization of alcohol dependence is still controversial. Accumulating evidence has shown the reliability and validity for the diagnosis of alcohol dependence in the ICD-10 and DSM-IV. However, the meaning and association of the respective diagnostic items, which are descriptive of representative symptoms, have hardly been examined. The core symptom of substance use disorder has been debated in various situations, but has never been elucidated logically.

METHODS

We consecutively registered 192 patients with alcohol-related problems who visited our hospital for the first time during a certain period. The relations and principal components among the checked items of the ICD-10 diagnostic criteria were examined statistically.

RESULTS

Three diagnostic items in the ICD-10 were strongly correlated with each other and were thought to form the core symptoms of alcohol dependence: "strong desire," "difficulties in controlling," and "neglect of pleasures." One major physical phenomenon, "withdrawal," seemed to complement the core symptoms in the diagnosis of alcohol dependence. Another physical phenomenon, "tolerance," was demonstrated to be a relatively independent item. The principal component analysis also demonstrated that the diagnostic item "difficulties in controlling" had the maximum component loading value, followed by 2 items, "neglect of pleasures" and "strong desire."

CONCLUSIONS

The core symptomatic elements in the diagnosis of alcohol dependence were statistically suggested in this study. Knowledge of the relations and components among the diagnostic items of alcohol dependence might also be applicable to other forms of substance use dependence and behavioral addiction.

Prevalence of HIV-Associated Neurocognitive Disorder (HAND) among Patients Attending a Tertiary Health Facility in Northern Nigeria

BACKGROUND

HIV-associated neurocognitive disorder (HAND) is a great source of morbidity in sub-Saharan African region. However, the magnitude of this problem remains largely uninvestigated despite having the largest number of population with HIV/AIDS. The aim of this study is to determine the prevalence of HAND among patients attending a tertiary health facility in Nigeria.

METHOD

We conducted a cross-sectional study among HIV-positive patients on antiretroviral therapy (ART) for at least 1 year. They were assessed using the International HIV Dementia Scale, Word Recall Test, Stick Design Test, Subjective Cognitive Complaint Questionnaire, Alcohol Use Disorder Identification Test, Drug Abuse Screening Test, Center for Epidemiological Study-Depression Scale, Instrumental Activity of Daily Living, and neurological examination. The CD4 count and viral load were determined for all the participants. A consensus diagnosis was made on each case based on the Frascati criteria. Data obtained were analyzed using "SPSS" for Windows version 15.

RESULTS

A total of 418 HIV-positive patients participated in the study, of which 325 (77.8%) are females. The mean age (standard deviation) of the participants was 37.2 (9.3) years. The prevalence of HAND was 21.5% (95% confidence interval [CI] = 17.6%-25.4%), of which 9.6% were asymptomatic. The significant predictors of HAND in this study are duration of illness (odds ratio [OR] = 1.33 P < .001), detectable viral load (OR = 0.19, P < .001), CD4 count (OR = 0.99, P < .001), education (OR = 0.94, P = .011), stopping medication (OR = 3.55 P = .01), and severity of illness (OR = 1.24, P = .005).

CONCLUSION

One-fifth of the HIV-positive patients in this study had HAND. Various sociodemographic and clinical features were related to the prevalence of HAND.

How should prevalence of alcohol use disorders be assessed globally?

Alcohol is a major risk factor for global burden of disease, and alcohol use disorders make up a considerable portion of this burden. Up to now, prevalence of alcohol use disorders has been estimated based on general population surveys with the Composite International Diagnostic Interview (CIDI) as the gold standard for assessment. However, three major problems have been identified with the current conceptualization of alcohol use disorders and its measurement via CIDI: cultural specificity of key criteria measured such as loss of control; lack of convergence of diagnoses identified by CIDI with clinically relevant diagnoses in primary health care; and impact of stigma on measurement. As a solution, it is proposed to measure alcohol use disorders via heavy drinking over time, with thresholds taken from the European Medicines Agency (60 and more grams on average per day of pure alcohol for men, and 40+ grams for women). Current data on level of drinking (per capita consumption) assessed via taxation and other means allow for a measure of less bias. If these thresholds are considered too low and there is more emphasis on need for specialized treatment, then thresholds for very heavy drinking can be taken as alternatively (100+, and 60+ grams per day pure alcohol for men and women, respectively).

The use of alcohol use disorders identification test (AUDIT) in detecting alcohol use disorder and risk drinking in the general population: validation of AUDIT using schedules for clinical assessment in neuropsychiatry

BACKGROUND

The alcohol use disorders identification test (AUDIT) and AUDIT-Consumption (AUDIT-C) are commonly used in population surveys but there are few validations studies in the general population. Validity should be estimated in samples close to the targeted population and setting. This study aims to validate AUDIT and AUDIT-C in a general population sample (PART) in Stockholm, Sweden.

METHODS

We used a general population subsample age 20 to 64 that answered a postal questionnaire including AUDIT who later participated in a psychiatric interview (n = 1,093). Interviews using Schedules for Clinical Assessment in Neuropsychiatry was used as criterion standard. Diagnoses were set according to the fourth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Agreement between the diagnostic test and criterion standard was measured with area under the receiver operator characteristics curve (AUC).

RESULTS

A total of 1,086 (450 men and 636 women) of the interview participants completed AUDIT. There were 96 individuals with DSM-IV-alcohol dependence, 36 DSM-IV-Alcohol Abuse, and 153 Risk drinkers. AUCs were for DSM-IV-alcohol use disorder 0.90 (AUDIT-C 0.85); DSM-IV-dependence 0.94 (AUDIT-C 0.89); risk drinking 0.80 (AUDIT-C 0.80); and any criterion 0.87 (AUDIT-C 0.84).

CONCLUSIONS

In this general population sample, AUDIT and AUDIT-C performed outstanding or excellent in identifying dependency, risk drinking, alcohol use disorder, any disorder, or risk drinking.

Gender Aspects of Affiliation with Alcoholics Anonymous after Treatment

Studies incorporating gender aspects of post-treatment affiliation with Alcoholics Anonymous (AA) have often focused on meeting attendance, disregarding behavioral indicators of affiliation. This article describes meeting attendance and affiliative behaviors in a Swedish treatment sample of 112 men and 40 women, and also identifies predictors of high affiliation. While no gender differences were found for meeting attendance, more women than men reported that they had called an AA member for help, had experienced a spiritual awakening, and read AA literature after treatment. Bivariate analyses identified a treatment goal of abstinence as predictive of high affiliation for both sexes, and in a multivariate context, female gender, a treatment goal of abstinence and pre-treatment AA exposure increased the likelihood of high affiliation (R2 = .31). Findings suggest that the affiliation process differs by gender, but reflect study methodology and Swedish AA culture, so that these issues need further exploration.

Lifetime and 12 Months Prevalence of Alcohol Use and Alcohol Use Disorders Among Soldiers Residing in a Military Community in Ibadan

OBJECTIVE

Aims of the study were to determine lifetime and 12 months prevalence of alcohol use and alcohol use disorders and the profile of problems associated with the diagnoses of alcohol use disorders among a military population in Nigeria.

METHOD

In this descriptive cross-sectional study, 223 military officers were interviewed by multistage stratified systematic sampling method. The Composite International Diagnostic Interview (CIDI) version 7.0 was used to generate data on prevalence of lifetime and current alcohol use, alcohol use disorders, and associated profile of problems. Chi square statistics, Wilcoxon-signed rank test, and binary regression analysis were used to explore the correlates of alcohol use and alcohol use disorder. All analyses were carried using SPSS Version 17.0.

RESULTS

Prevalence of lifetime alcohol use was 76.0%, 12 months prevalence was 53.9%, and frequent binge drinking was reported in 6.7% of respondents. Predictors of lifetime alcohol use were: Hausa/Fulani ethnicity OR = 1.51, 95% CI (1.11-8.71), Igbo ethnicity OR = 1.46, 95% CI (1.09-7.01), involvement in combat OR = 1.41, 95% CI (1.01-6.16). Predictors of 12 months alcohol use were: Hausa/Fulani ethnicity OR = 1.98, 95% CI (1.25-8.71), involvement in combat OR = 1.39 95% CI (1.01-5.28) and junior rank soldier OR = 2.08, 95% CI (1.47-8.99) while predictors of lifetime alcohol use disorders were: Hausa/Fulani ethnicity OR = 2.22, 95% CI (1.03-6.99) and involvement in combat OR = 2.04 95% CI (1.12-6.81).

CONCLUSION

Alcohol misuse is highly prevalent in the Nigerian military and its associated factors exemplify the common "military drinking culture."

Severity of mental illness as a result of multiple childhood adversities: US National Epidemiologic Survey

PURPOSE

To examine patterns of childhood adversity, their long-term consequences and the combined effect of different childhood adversity patterns as predictors of subsequent psychopathology.

METHODS

Secondary analysis of data from the US National Epidemiologic Survey on alcohol and related conditions. Using latent class analysis to identify childhood adversity profiles; and using multinomial logistic regression to validate and further explore these profiles with a range of associated demographic and household characteristics. Finally, confirmatory factor analysis substantiated initial latent class analysis findings by investigating a range of mental health diagnoses.

RESULTS

Latent class analysis generated a three-class model of childhood adversity in which 60 % of participants were allocated to a low adversity class; 14 % to a global adversities class (reporting exposures for all the derived latent classes); and 26 % to a domestic emotional and physical abuse class (exposed to a range of childhood adversities). Confirmatory Factor analysis defined an internalising-externalising spectrum to represent lifetime reporting patterns of mental health disorders. Using logistic regression, both adversity groups showed specific gender and race/ethnicity differences, related family discord and increased psychopathology.

CONCLUSIONS

We identified underlying patterns in the exposure to childhood adversity and associated mental health. These findings are informative in their description of the configuration of adversities, rather than focusing solely on the cumulative aspect of experience. Amelioration of longer-term negative consequences requires early identification of psychopathology risk factors that can inform protective and preventive interventions. This study highlights the utility of screening for childhood adversities when individuals present with symptoms of psychiatric disorders.

Identifying Sensitive Periods for Alcohol Use: The Roles of Timing and Chronicity of Child Physical Abuse

BACKGROUND

Childhood maltreatment, particularly physical abuse (PA), increases the risk of alcohol use during young adulthood. Although prior research underscores the importance of examining the roles of PA-event characteristics such as timing of and chronicity of PA in initiating and maintaining alcohol use, few studies have explored the risk of developing alcohol use based on the timing and chronicity of PA.

METHODS

Using a community sample of 300 young adults (ages 18 to 25), this study examined how variations in timing and chronicity of PA relate to 4 distinct drinking behaviors including drinking frequency, binge drinking, alcohol-related problems, and alcohol use disorder (AUD) in the past 12 months. We controlled for sociodemographic information, other types of maltreatment, and common risk factors for alcohol use, such as psychological distress, parental alcoholism, and peer alcohol use in all analyses. This study used person-centered and developmental-stage-based characterizations of PA timing and chronicity to explore the relationship between timing and chronicity of PA and later drinking behaviors.

RESULTS

Overall, individuals who were physically abused, particularly during adolescence, and who chronically experienced PA, reported higher levels of monthly drinking frequency and more pathological drinking behaviors such as binge drinking, alcohol-related problems, and AUD.

CONCLUSIONS

This study describes the specific roles of timing and chronicity of PA in understanding the increased vulnerability to alcohol use among victims of PA. Our findings suggest that PA during adolescence and chronic PA are related to problematic drinking behaviors in young adulthood.

Childhood emotional abuse, negative emotion-driven impulsivity, and alcohol use in young adulthood

Childhood emotional abuse has been linked to problematic alcohol use in later life but there is a paucity of empirically based knowledge about the developmental pathways linking emotional abuse and alcohol use in young adulthood. Using a community sample of young individuals aged 18-25 (N=268; female 52%), we performed structural equation modeling to investigate whether emotional abuse influences alcohol use through urgent personality trait and to determine pathways for these effects in a multivariate context. We also examined variations in these pathways by four different alcohol use outcomes including frequency of alcohol use, binge drinking, alcohol-related problems, and alcohol use disorders (AUD). The present study found that emotional abuse was related to urgency, which in turn influenced four types of alcohol use. Urgency may play a significant role in linking childhood maltreatment to alcohol use in young adulthood.

Who receives treatment for alcohol use disorders in the European Union? A cross-sectional representative study in primary and specialized health care

BACKGROUND

Alcohol use disorders (AUDs) are highly prevalent in Europe, but only a minority of those affected receive treatment. It is therefore important to identify factors that predict treatment in order to reframe strategies aimed at improving treatment rates.

METHODS

Representative cross-sectional study with patients aged 18-64 from primary health care (PC, six European countries, n=8476, data collection 01/13-01/14) and from specialized health care (SC, eight European countries, n=1762, data collection 01/13-03/14). For descriptive purposes, six groups were distinguished, based on type of DSM-IV AUD and treatment setting. Treatment status (yes/no) for any treatment (model 1), and for SC treatment (model 2) were main outcome measures in logistic regression models.

RESULTS

AUDs were prevalent in PC (12-month prevalence: 11.8%, 95% confidence interval (CI): 11.2-12.5%), with 17.6% receiving current treatment (95%CI: 15.3-19.9%). There were clear differences between the six groups regarding key variables from all five predictor domains. Prediction of any treatment (model 1) or SC treatment (model 2) was successful with high overall accuracy (both models: 95%), sufficient sensitivity (model 1: 79%/model 2: 76%) and high specificity (both models: 98%). The most predictive single variables were daily drinking level, anxiety, severity of mental distress, and number of inpatient nights during the last 6 months.

CONCLUSIONS

Variables from four domains were highly predictive in identifying treatment for AUD, with SC treatment groups showing very high levels of social disintegration, drinking, comorbidity and functional losses. Earlier intervention and formal treatment for AUD in PC should be implemented to reduce these high levels of adverse outcomes.

The Comorbid and Individual Impacts of Maternal Depression and Substance Dependence on Parenting and Child Behavior Problems

Maternal depression, substance dependence, and the comorbidity of these conditions are highly prevalent risk factors among families involved with Child Protective Services (CPS). Data from the National Survey of Child and Adolescent Well-Being I (NSCAW I) were analyzed to examine the influence of maternal substance dependence, depression, and comorbidity on parenting and child behavior over 36-months among children reported to CPS who remained in the home at all waves. Although neglect and child behavior problems were highest for mothers with comorbidity at baseline, mothers with substance dependence had the poorest self-reported parenting and child behavior problems over time. Results indicate a need for intensive targeted services to address the complex needs of CPS-involved mothers with substance dependence and their in-home children.
