RESUMO
BACKGROUND: Chronic, heavy alcohol use is associated with multiple health problems, including premature death. Further, the clinical presentation of alcohol dependence may differentially affect and predict the long-term health consequences of affected individuals. Subtypes of alcohol dependence based upon treatment intake information can help identify homogenous groups of patients for treatment purposes, but have not been used to predict long-term outcomes. The current study examined mortality in a 36-year posttreatment interval among 4 subtypes of alcohol-dependent patients based upon their initial intake data. METHODS: Extensive baseline data were collected from n = 316 male and female patients receiving inpatient treatment for alcohol dependence between 1980 and 1982. Four alcohol dependent subtypes (Del Boca & Hesselbrock, Alcohol Health Res World, 20:56, 1996) derived from the baseline data were used to examine the 1-year posttreatment drinking status and the risk of death 36 years postdischarge. Public records were used to determine patient deaths in the 36 years since discharge. RESULTS: At the 36-year follow-up interval since discharge, 68.4% of the sample had died. The 4 subtypes were found to be associated with different rates of resumption of regular drinking in the first year posttreatment and a differential risk of mortality. An increased risk for returning to regular drinking (once a week or more) and early death were associated with subtypes defined, in part, by conduct problems and externalizing disorders. Regardless of subtype membership, women had the highest risk of death following treatment. CONCLUSIONS: This study demonstrates the clinical usefulness of subtypes of alcohol dependence for examining different alcohol use outcomes, including predicting mortality. The increased risks for returning to regular drinking once a week or more and early death posttreatment among subtypes associated with conduct problems and externalizing disorders suggest the need for continued monitoring and possible additional intervention postdischarge.

BACKGROUND AND OBJECTIVES: This special issue brings together papers focusing on a wide range of topics relevant to the research and understanding of the role of race/ethnicity and genetic variation for the susceptibility of developing an alcohol use disorder (AUD). METHODS: The key findings from the issue's 10 articles are reviewed and organized here around three topics: I: addictive behaviors and potential environmental influences; II: a focus on four racial/ethnic groups; and III: special methodologies. RESULTS: Several potential next steps in improving effective research strategies are highlighted: (1) implementing best practices for outreach and community engagement may reduce reluctance to participate; (2) recruiting adequately sized and racially/ethnically diverse samples will require new collaborations with investigators who successfully work in diverse communities; (3) identifying and assessing environmental influences that are both unique to, and common among, racial/ethnic groups may inform preventions for AUD; (4) use of standardized measures will facilitate the generation of larger samples and meta-analysis of research findings; and (5) use of better analytic approaches and experimental methods will improve replication in gene finding research and help advance new areas of research. CONCLUSIONS: Genetic research of AUD in diverse racial/ethnic populations is advancing. The articles in this issue examined the general theme of including diverse population groups in genetic studies and offered potential strategies for addressing some common problems. SCIENTIFIC SIGNIFICANCE: Greater inclusion of diverse racial/ethnic populations in this research is important to ensure that the benefits of new knowledge and technology are equally shared.

This special issue of The American Journal on Addictions is an extension of a workshop held at the Research Society on Alcoholism (2015) highlighting several important issues related to studies of the genetic bases of alcohol use disorder among racially/ethnically diverse populations. While not exhaustive in their coverage, the papers in this special issue focus on three important topics: (1) the importance of considering the social and environmental context in genetic analyses; (2) social and cultural considerations for engaging diverse communities in genetic research; and (3) methodologies related to phenotype development for use with racially/ethnically diverse populations. A brief overview of each paper included in these three sections is presented. The issue concludes with additional considerations for genetic research with racially/ethnically diverse population groups along with a commentary. (Am J Addict 2017;26:422-423).

The moderating effects of ethnicity and gender on factors associated with physical health consequences in adults manifesting alcohol dependence were examined using data from the 2001-2002 US National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Black and white respondents with a lifetime diagnosis of DSM-IV alcohol dependence were selected for the study (n = 3,852). A multiple-group structural equation model tested ethnicity, gender, and intervening variables as predictors of physical health status in alcohol-dependent men and women. Study findings offer implications for clinical practice with alcohol-dependent individuals by identifying likely target groups and problems for intervention.

OBJECTIVE: The comorbidity of alcohol and substance use disorders among persons with bipolar disorder is elevated, as indicated by epidemiological and clinical studies. Following alcohol use, cannabis is the most frequently used and abused illicit substance among bipolar individuals, and such use may lead to comorbid cannabis use disorders (CUD). Previous research indicated that CUDs were related to a more severe course of bipolar disorder and higher rates of other comorbid alcohol and substance use disorders. Few studies, however, have conducted longitudinal research on this comorbidity. The aim of this study is to investigate the influence of CUD on the course of bipolar I and II individuals during a 5-year follow-up. METHODS: The characteristics of bipolar disorder, cannabis use disorders, and other alcohol and substance use disorders, as well as comorbid mental disorders, were assessed using a standardized semi-structured interview (SSAGA) at both baseline and the 5-year follow-up. N = 180 bipolar I and II patients were subdivided into groups of with and without comorbid cannabis use disorders (CUD). RESULTS: Of the 77 bipolar I and 103 bipolar II patients, n = 65 (36.1%) had a comorbid diagnosis of any CUD (DSM-IV cannabis abuse or dependence). Comorbid bipolar patients with CUD had higher rates of other substance use disorders and posttraumatic stress disorders, more affective symptoms, and less psychosocial functioning at baseline and at 5-year follow-up. In contrast to previously reported findings, higher rates of anxiety disorders and bipolar disorder complications (e.g., mixed episodes, rapid cycling, and manic or hypomanic episodes) were not found. The effect of CUD on other substance use disorders was confirmed using moderation analyses. CONCLUSIONS: A 5-year prospective evaluation of bipolar patients with and without CUD confirmed previous investigations, suggesting that the risk of other substance use disorders is significantly increased in comorbid individuals. CUD has a moderation effect, while no effect was found for other mental disorders. Findings from this study and previous research may be due to the examination of different phenotypes (Cannabis use vs. CUD) and sample variation (family study vs. clinical and epidemiological populations).
RESUMO
The study examined the effectiveness of a culturally-adapted Strengthening Families Program (SFP) for Latinos to reduce risks for alcohol and drug use in children. Latino families, predominantly Puerto Rican, with a 9-12 year old child and a parent(s) with a substance abuse problem participated in the study. Pre- and post-tests were conducted with each family. Parental stress, parent-child dysfunctional relations, and child behavior problems were reduced in the families receiving the intervention; family hardiness and family attachment were improved. Findings contribute to the validation of the SFP with Latinos, and can be used to inform social work practice with Puerto Rican families.
RESUMO
AIMS: This paper provides an overview of several multidimensional empirically derived typologies of alcohol use disorders that have been derived primarily for research purposes in relation to their clinical utility. METHODS: Studies using multivariate statistical methods for identifying homogeneous groups of subjects were selected for inclusion. Theoretically based typologies were not included in this review. RESULTS: While formal diagnostic criteria typically identify separate categories of alcohol abuse and dependence, several studies using different statistical methods consistently suggest as many as four homogeneous types of alcoholism: a chronic/severe type, a depressed/anxious type, a mildly affected type and an antisocial type. CONCLUSIONS: Even though the longitudinal outcomes of few empirically derived subtypes have been examined, alcoholism typologies remain a viable and potentially valuable tool for investigating etiological pathways, the effectiveness of treatments and the long-term course of alcohol use disorders.

OBJECTIVE: In previous studies, factors related to a history of suicide attempts in persons with alcohol dependence have included sociodemographic variables, a more severe course of alcoholism, additional substance use disorders, and psychiatric comorbidity. This 5-year prospective study evaluated attributes associated with suicide attempts in a group of treatment-seeking persons with alcohol dependence. Psychiatric comorbidity was examined in terms of a distinction between substance-induced and independent psychiatric disorders. METHOD: Semistructured interviews were conducted with 1,237 alcohol-dependent subjects from the Collaborative Study on the Genetics of Alcoholism both at an initial evaluation and at a 5-year follow-up. Clinically relevant information was gathered at baseline, and suicidal behavior, aspects of alcohol dependence, and drug use were evaluated at the follow-up interview. RESULTS: Alcohol-dependent subjects (N=56) with suicide attempts during the follow-up period were more likely than subjects with no suicide attempts (N=1,181) to have made prior attempts. Other factors related to future suicide attempts in univariate analyses included younger age, being separated or divorced, other drug dependence, substance-induced psychiatric disorders, and indicators of a more severe course of alcoholism. Gender did not predict future attempts. CONCLUSIONS: A 5-year prospective evaluation of attributes associated with suicide attempts among alcohol-dependent persons identified factors that contributed to a small but significant proportion of the variance for future suicidal behavior.

Although women generally have been subjects of alcohol research less often than men, gender can be used as a defining characteristic in subtyping schemes. Whether the sexes actually differ in aspects of their alcoholism, such as in etiology and degree of severity, however, is not known. Analyzing a sample of male and female alcoholics using several different statistical methods, the researchers found that men and women with either a severe or mild form of alcoholism differed little in their character profiles and etiologies. Women and men with moderately severe alcoholism, however, tended to differ with respect to co-occurring psychopathologies (e.g., depression or antisocial personality) and the degree to which they drank to relieve other conditions (e.g., boredom). These findings suggest that different forms of alcoholism treatment may be most effective for men and women with moderately severe alcoholism. However, as is the case with any subtyping scheme, this conclusion cannot be applied to the general population without further research.
RESUMO
Since completion of the mapping of the human genome in early 2000, tremendous progress has been made in the identification of many different genes associated with our health and across diseases. Although social work researchers are not expected to conduct genetic research at the molecular level, it is imperative that we are able to understand the basic genetic findings related to behavioral problems and are able to translate and integrate this information into psychosocial treatment approaches and program development. This article is an introduction and overview of genetic approaches, using studies of the genetics of alcoholism to exemplify important issues. The literature review is not comprehensive and focuses primarily on the Collaborative Study on the Genetics of Alcoholism project as an example of a multidisciplinary and integrative approach to the genetic study of a major health problem often encountered in social work practice.

OBJECTIVES: This article presents an overview of the current literature on biological markers for alcoholism, including markers associated with the pharmacological effects of alcohol and markers related to the clinical course and treatment of alcohol-related problems. Many of these studies are well known, while other studies cited are new and still being evaluated. METHODS: In this paper we first describe known biomarkers of alcohol-related disorders, review their features and the problems involved in their use. We then consider future developments on biomarkers and their possible impact on the field. RESULTS: More recent findings cited include the work on type 7 adenylcyclase (AC) polymorphism and its lower expression levels in female alcoholics. Neuroimaging studies involving biomarkers have also reported brain volume reductions of gray and white matter, including amygdala and subcortical regions in alcoholic patients, while a high association between the copy number variations (CNVs) in 6q14.1/5q13.2 and alcohol dependence has more recently been identified in genetic studies. CONCLUSIONS: In addition to their possible importance for diagnosis, biomarkers may have utility for predicting prognosis, progression of the disorder, the development of new treatments, and monitoring treatment effects. Although such findings should be verified in independent studies, the search for new biomarkers is continuing. Several potential candidate biomarkers have been found recently in blood, imaging, and genetic studies with encouraging results.

AIMS: To examine whether DSM-IV symptoms of substance dependence are psychometrically equivalent between existing community-sampled and clinically overselected studies. PARTICIPANTS: A total of 2476 adult twins born in Minnesota and 4121 unrelated adult participants from a case-control study of alcohol dependence. MEASUREMENTS: Life-time DSM-IV alcohol, marijuana and cocaine dependence symptoms and ever use of each substance. DESIGN: We fitted a hierarchical model to the data, in which ever use and dependence symptoms for each substance were indicators of alcohol, marijuana or cocaine dependence which were, in turn, indicators of a multi-substance dependence factor. We then tested the model for measurement invariance across participant groups, defined by study source and participant sex. FINDINGS: The hierarchical model fitted well among males and females within each sample [comparative fit index (CFI) > 0.96, Tucker-Lewis index (TLI) > 0.95 and root mean square error of approximation (RMSEA) < 0.04 for all], and a multi-group model demonstrated that model parameters were equivalent across sample- and sex-defined groups (ΔCFI = 0.002 between constrained and unconstrained models). Differences between groups in symptom endorsement rates could be expressed solely as mean differences in the multi-substance dependence factor. CONCLUSIONS: Life-time substance dependence symptoms fitted a dimensional model well. Although clinically overselected participants endorsed more dependence symptoms, on average, than community-sampled participants, the pattern of symptom endorsement was similar across groups. From a measurement perspective, DSM-IV criteria are equally appropriate for describing substance dependence across different sampling methods.

Race and gender may be important considerations for recognizing alcohol related problems in Black and White young adults. This study examined the prevalence and age of onset of individual alcohol problems and alcohol problem severity across race and gender subgroups from a longitudinal study of a community sample of adolescents followed into young adulthood (N=166; 23-29 yrs. old who were drinkers). All alcohol problems examined first occurred when subjects were in their late teens and early 20s. Drinking in hazardous situations, blackouts, and tolerance were the most common reported alcohol problems. In race and gender comparisons, more males than females experienced alcohol problems. Blacks generally had a later age of onset of alcohol problems. Multivariate regressions showed greater alcohol problem severity in males compared to females, but no significant differences between Blacks and Whites. Education, family environment and earlier alcohol use behaviors and expectancies were reliable predictors of alcohol problem severity in young adulthood. White males were at particular risk for experiencing more severe alcohol problems. Findings may inform the design of more targeted interventions for alcohol problems in different populations.

This article provides an overview of the characteristics of adolescent alcohol use, normative and subgroup variations in drinking behavior, and the important factors associated with an increased risk for developing alcohol problems in later adolescence and young adulthood. Parental or family histories of alcoholism, temperament traits, conduct problems, cognitive functioning, alcohol expectancies, and peer and other social relations are identified as factors influencing an adolescent's susceptibility for initiating a variety of alcohol use behaviors. The deviance prone model, proposed by Sher in 1991, is presented as an important tool for testing possible relationships among the various risk factors and their sequencing that leads to early adolescent alcohol use and drug initiation. It is also possible to extend the model to allow for an examination of the complex interplay of risk factors that lead to the development of alcohol use problems in late adolescence and young adults.

OBJECTIVE: This study examined the influence of ethnicity on factors affecting alcohol-use behaviors in a community sample of white, black, and Hispanic youth (N = 323). Conduct problems, positive alcohol expectancies, and socioeconomic status were expected to mediate the effect of negative affectivity and a paternal history of substance dependence on the age at onset of regular drinking and the frequency of drinking. METHOD: Subjects ages 14-21 (57.9% female; 60.7% white) were interviewed along with their fathers at baseline (Time 1), and subjects only were interviewed again 5 years later (Time 2). A structural equation model was used to test a deviance proneness model for predicting drinking behaviors and to evaluate differences on model paths by ethnicity. RESULTS: Ethnic group membership moderated mediational pathways linked to the onset of regular alcohol use but not to drinking frequency. An increase in the number of childhood conduct problems predicted an earlier age at onset of regular drinking for blacks, whereas more positive alcohol expectancies were associated with an earlier initiation of regular drinking for whites and Hispanics. CONCLUSIONS: Findings from this study provide evidence that risk factors for alcohol use in adolescents and young adults vary according to ethnic group.

Alcohol dependence among Native Americans and Alaska Natives is twice that found in the general population. Alaska Natives are 7 times more likely to die of alcohol-related problems. This study investigated differences in the course and consequences of alcoholism and co-occurring polysubstance dependence in a sample of 582 alcohol-dependent Alaska Natives undergoing inpatient lifetime treatment in Anchorage between 1994 and 1999. Mean age was 33.9 years. Information on lifetime psychiatric symptoms and disorders was collected by using the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), a research diagnostic interview. Results indicate that in addition to alcohol dependence, the majority of subjects were dependent on other substances. Marijuana dependence was most common, followed by dependence on cocaine and opiates. Compared with subjects not dependent on any other drugs, subjects with co-occurring alcohol and opiate dependence showed significant differences in relation to age of first regular drink, intoxication, tolerance and withdrawal symptoms, number of medical problems, and number of psychological problems. More research and specific clinical interventions are needed for alcohol- and opiate-dependent Alaska Natives. Findings indicate the need for prevention and interventions in alcohol and illicit drug abuse in this population at an early age.

This study examined ethnic and gender differences of psychiatric comorbidity among alcohol dependent men and women from four ethnic groups: Alaska Native, Caucasians, African Americans, and Hispanics. The data were obtained through individual standardized interview; DSM-III-R diagnoses were obtained via a computer algorithm. The subjects included 1177 Caucasians, 361 African Americans, 93 Hispanics and 486 Alaska Natives. Significant ethnic differences were found in relation to age of onset of alcohol and multiple substance dependence and psychiatric comorbidity. Ethnic differences were also noted with regard to the health care utilization.
