Abstract
BACKGROUND Although the link between alcohol involvement and behavioral phenotypes (e.g. impulsivity, negative affect, executive function [EF]) is well-established, the directionality of these associations, specificity to stages of alcohol involvement, and extent of shared genetic liability remain unclear. We estimate longitudinal associations between transitions among alcohol milestones, behavioral phenotypes, and indices of genetic risk. METHODS Data came from the Collaborative Study on the Genetics of Alcoholism (n = 3681; ages 11-36). Alcohol transitions (first: drink, intoxication, alcohol use disorder [AUD] symptom, AUD diagnosis), internalizing, and externalizing phenotypes came from the Semi-Structured Assessment for the Genetics of Alcoholism. EF was measured with the Tower of London and Visual Span Tasks. Polygenic scores (PGS) were computed for alcohol-related and behavioral phenotypes. Cox models estimated associations among PGS, behavior, and alcohol milestones. RESULTS Externalizing phenotypes (e.g. conduct disorder symptoms) were associated with future initiation and drinking problems (hazard ratio (HR)⩾1.16). Internalizing (e.g. social anxiety) was associated with hazards for progression from first drink to severe AUD (HR⩾1.55). Initiation and AUD were associated with increased hazards for later depressive symptoms and suicidal ideation (HR⩾1.38), and initiation was associated with increased hazards for future conduct symptoms (HR = 1.60). EF was not associated with alcohol transitions. Drinks per week PGS was linked with increased hazards for alcohol transitions (HR⩾1.06). Problematic alcohol use PGS increased hazards for suicidal ideation (HR = 1.20). CONCLUSIONS Behavioral markers of addiction vulnerability precede and follow alcohol transitions, highlighting dynamic, bidirectional relationships between behavior and emerging addiction.

Abstract
Child maltreatment is a pervasive social problem often perpetuated by family members and is related to a wide array of negative life outcomes. Although substance use is an outcome commonly associated with experiences of child maltreatment, not all individuals who experience maltreatment struggle with such issues. Many individuals can positively adapt to experiences of maltreatment based on levels of resilience and susceptibility. Research suggests that genetic differences may partly explain why negative outcomes develop for some, but not for others. Few studies have examined the extent to which genetic and environmental factors influence the longitudinal association between child maltreatment and varying forms of substance use, leaving a fundamental gap in our current understanding of this association. The current study aims to address this gap by analyzing a sample of twins from the National Longitudinal Study of Adolescent to Adult Health (Add Health). Findings from a series of univariate and bivariate biometric models reveal that the longitudinal associations between maltreatment, cigarette use, and marijuana use are accounted for by additive genetic and nonshared environmental factors. Moreover, the magnitude of the contribution varies across unique subgroups of cigarette and marijuana use. Directions for future research and theoretical implications are discussed.

Abstract
Students with anxiety or mood issues tend to engage in more problematic drinking, but less is known about those students with co-occurring anxiety and mood symptoms. This study compares rates of weekly alcohol use, hazardous drinking, and alcohol-related negative consequences in a sample of 699 college students with symptoms of comorbid anxiety and depression (35% of the sample) compared to their non-symptomatic drinking peers, as well as the moderating role of gender. We found main effects of gender and comorbidity status such that participants with comorbid symptoms of anxiety and depression or who were male reported higher rates of weekly alcohol use, more hazardous drinking and more alcohol-related negative consequences than their non-symptomatic and female peers. We also found an interaction effect on alcohol-related negative consequences such that male participants with comorbid anxiety and depression reported more alcohol-related negative consequences than all other groups. These findings imply that while any student drinker with both anxiety and depression may be considered at higher risk for problematic drinking behavior, the risk of negative consequences in particular may be highest in the men of that group.

Abstract
BACKGROUND Depressive symptoms are common during abstinence from psychoactive substances. Research caveats limit the study of persistence of significant depressive symptoms beyond four weeks of abstinence. This prospective study examined the course and correlates of depressive symptoms in patients with alcohol or opioid use disorder over 5-8 weeks. METHODS Sample consisted of 100 men randomly selected out of 307 inpatient men with either alcohol or opioid use disorder. Weekly assessments focused on depressive symptoms (HDRS, BDI), and their correlates (HAM-A for anxiety symptoms, CIWA-Ar and COWS for withdrawal symptoms, OCDS and OCDUS for craving for alcohol and opioids respectively). Other correlates assessed were severity of dependence and family support. PRISM (Psychiatric Research Interview for Substance and Mental disorders) was used for diagnosis of substance-induced depression and major depressive episode. Repeated measures ANOVA was used for weekly comparison of depressive symptoms. RESULTS Participants were dependent on opioids (56%), or alcohol (41%), or both (3%). Mean age was 33.5 years. Eighty-eight participants completed the study. Substance-induced depressive episode was diagnosed by PRISM in 59% participants. Weekly assessments of depressive symptoms recorded significant reductions (p < 0.0001; Wilk's Lambda for HDRS and BDI 137.01 and 105.4 respectively). Baseline depressive symptoms correlated significantly with anxiety, withdrawal symptoms, and negatively with social support. No participant was diagnosed with a major depressive episode at 6-8 weeks. CONCLUSION Depressive symptoms in early alcohol or opioid abstinence resolve significantly over a month; therefore, clinicians should exercise watchful waiting before starting antidepressant therapy.

Abstract
Mental disorders are highly comorbid and occur together with physical diseases, which are often considered to arise from separate pathogenic pathways. We observed in alcohol-dependent patients increased serum activity of neutral sphingomyelinase. A genetic association analysis in 456,693 volunteers found associations of haplotypes of SMPD3 coding for NSM-2 (NSM) with alcohol consumption, but also with affective state, and bone mineralisation. Functional analysis in mice showed that NSM controls alcohol consumption, affective behaviour, and their interaction by regulating hippocampal volume, cortical connectivity, and monoaminergic responses. Furthermore, NSM controlled bone-brain communication by enhancing osteocalcin signalling, which can independently supress alcohol consumption and reduce depressive behaviour. Altogether, we identified a single gene source for multiple pathways originating in the brain and bone, which interlink disorders of a mental-physical co-morbidity trias of alcohol abuse-depression/anxiety-bone disorder. Targeting NSM and osteocalcin signalling may, thus, provide a new systems approach in the treatment of a mental-physical co-morbidity trias.

Abstract
Psychoactive drugs with addiction potential are widely used by people of virtually all cultures in a non-addictive way. In order to understand this behaviour, its population penetrance, and its persistence, drug instrumentalization was suggested as a driving force for this consumption. Drug instrumentalization theory holds that psychoactive drugs are consumed in a very systematic way in order to make other, non-drug-related behaviours more efficient. Here, we review the evolutionary origin of this behaviour and its psychological mechanisms and explore the neurobiological and neuropharmacological mechanisms underlying them. Instrumentalization goals are discussed, for which an environmentally selective and mental state-dependent consumption of psychoactive drugs can be learned and maintained in a non-addictive way. A small percentage of people who regularly instrumentalize psychoactive drugs make a transition to addiction, which often starts with qualitative and quantitative changes in the instrumentalization goals. As such, addiction is proposed to develop from previously established long-term drug instrumentalization. Thus, preventing and treating drug addiction in an individualized medicine approach may essentially require understanding and supporting personal instrumentalization goals.

Abstract
There is still no widely effective pharmacotherapy for alcohol addiction available in the clinic. FK506-binding protein 51 (FKBP51) is a negative regulator of the glucocorticoid receptor signaling pathway that regulates the stress-induced glucocorticoid feedback circuit. Here we asked whether selective inhibitors of FKBP51, exemplified by SAFit2, may serve as a new pharmacological strategy to reduce alcohol consumption and conditioned alcohol effects in a mouse model. We report that a relatively short treatment with SAFit2 (20 mg/kg, ip) reduces ongoing 16 vol% alcohol consumption when administered during free access to alcohol in a two-bottle free-choice test. SAFit2 was also able to reduce alcohol consumption when given during an abstinence period immediately before relapse. In contrast, SAFit2 did not affect alcohol consumption when given during a relapse period after repeated withdrawal from alcohol. SAFit2 (10 and 20 mg/kg, ip) showed no effects when used in an intermittent drinking schedule. When 20 vol% alcohol was only available every other day, SAFit2 had no effect on drinking, no matter whether given during a drinking episode or the day before. SAFit2 (2 and 20 mg/kg, ip) did not affect the expression of an alcohol-induced conditioned place preference (CPP). However, SAFit2 was able to inhibit alcohol-induced reinstatement of an extinguished CPP in a dose-dependent way. Altogether, these data may suggest pharmacological inhibition of FKBP51 as a viable strategy to reduce alcohol seeking and consumption.

Abstract
Based on their pharmacological properties, psychoactive drugs are supposed to take control of the natural reward system to finally drive compulsory drug seeking and consumption. However, psychoactive drugs are not used in an arbitrary way as pure pharmacological reinforcement would suggest, but rather in a highly specific manner depending on non-pharmacological factors. While pharmacological effects of psychoactive drugs are well studied, neurobiological mechanisms of non-pharmacological factors are less well understood. Here we review the emerging neurobiological mechanisms beyond pharmacological reinforcement which determine drug effects and use frequency. Important progress was made on the understanding of how the character of an environment and social stress determine drug self-administration. This is expanded by new evidence on how behavioral alternatives and opportunities for drug instrumentalization generate different patterns of drug choice. Emerging evidence suggests that the neurobiology of non-pharmacological factors strongly determines pharmacological and behavioral drug action and may, thus, give rise for an expanded system's approach of psychoactive drug use and addiction.

Abstract
The objective of this study was to estimate a network model of risk and resilience factors of suicidal ideation among veterans. Two network models of suicidal ideation among Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn veterans (N = 276) incorporated key disorders, traumatic stress, and resilience constructs to contextualize suicidal ideation. Childhood trauma was positively connected with suicidal ideation and harassment and inversely connected with social support and distress tolerance. This exemplifies long-lasting associations between childhood trauma and re-victimization, emotion regulation, and ability to form supportive social relationships. A subsequent model including lower-order facets indicated that combat trauma was predominantly associated with posttraumatic stress disorder-intrusion symptoms. This study highlights the importance of addressing both risk and resilience to reduce suicide risk among veterans and increases understanding of factors that contribute to suicidal ideation.

Abstract
Many of the currently available treatments for obsessive-compulsive and related
disorders (OCRDs) such as pharmacotherapy augmentation strategies, partial hospitalization
programs, deep brain stimulation, and neurosurgery are efficacious for individuals
suffering from more severe forms of these conditions. Unfortunately, the application
of these treatments in milder forms of illness and subclinical samples, which affect a
substantial portion of the population, is not justifiable by their costs (e.g. cognitivebehavioral
therapy) and/or potential for side effects (serotonin-reuptake inhibitors associated
sexual side effects). As such, there is an urgent need to develop simple yet effective
treatments, such as modifiable lifestyle interventions, that can be employed on a broader
scale. Here, we review the current state of evidence that supports or refutes the efficacy of
lifestyle approaches for OCRDs. We focus on dimensions of lifestyle that are deemed important
for cardiovascular diseases; namely, physical activity, stress, sleep, diet and eating
behaviors, alcohol consumption, and smoking. Despite the relative scarcity of welldesigned
randomized controlled trials targeting unhealthy life styles in OCRDs, we found
meditation-based therapies and interventions focusing on eliminating sedentarism to be
promising approaches. In the future, these strategies may represent valid alternative for
subjects with subthreshold symptoms or at risk for OCRDs or other “compulsive” disorders.

Abstract
BACKGROUND AND AIMS The emergence of negative affective symptoms during the course of alcohol use disorders (AUDs) (e.g. 'dark side' symptoms) has been suggested theoretically; however, the description of their occurrence is limited. This study operationalized two negative affect symptoms and tested the strength of association between these phenotypes and (1) indicators of the clinical course of the severity of AUD, (2) comorbid Axis I psychiatric disorders, suicidal behaviors and trait neuroticism and (3) whether participants reported drinking to relieve the negative affective symptoms. DESIGN A retrospective cross-sectional study was used to evaluate associations, using logistic regression, between the two negative affective symptoms and clinical measures of AUD severity and progression as well as comorbidity with other psychiatric disorders and conditions, adjusted for demographic characteristics. SETTING US community-based studies. PARTICIPANTS A total of 2568 individuals with AUDs obtained from larger population studies that targeted individuals of European American (n = 1663), Mexican American and American Indian (n = 905) ancestry. MEASUREMENTS Semi-Structured Assessment for the Genetics of Alcoholism was used to ascertain the two 'dark side' phenotypes, clinical diagnoses, the clinical course of AUD and associated symptoms. The two phenotypes were: (1) being anxious or depressed when trying to cut down or stop drinking and (2) experiencing disabling depression for more than 24 hours while drinking. FINDINGS Both phenotypes were found to be rare in mild and moderate use disorder and highly prevalent in severe AUDs. Having an independent anxiety or affective disorder and elevated scores on trait neuroticism were also associated significantly with the occurrence of both symptoms, as was alcohol 'craving', elevated treatment-seeking, suicidal behaviors and drinking to relieve the symptoms. CONCLUSIONS Affective symptoms are common in severe alcohol use disorders are associated with a history of independent affective/anxiety disorders, neuroticism and suicidal behaviors; and may promote further heavy drinking.

Abstract
The original Human Connectome Project yielded a rich data set on structural and functional connectivity in a large sample of healthy young adults using improved methods of data acquisition, analysis, and sharing. More recent efforts are extending this approach to include infants, children, older adults, and brain disorders. This paper introduces and describes the Human Connectome Project in Aging (HCP-A), which is currently recruiting 1200 + healthy adults aged 36 to 100+, with a subset of 600 + participants returning for longitudinal assessment. Four acquisition sites using matched Siemens Prisma 3T MRI scanners with centralized quality control and data analysis are enrolling participants. Data are acquired across multimodal imaging and behavioral domains with a focus on factors known to be altered in advanced aging. MRI acquisitions include structural (whole brain and high resolution hippocampal) plus multiband resting state functional (rfMRI), task fMRI (tfMRI), diffusion MRI (dMRI), and arterial spin labeling (ASL). Behavioral characterization includes cognitive (such as processing speed and episodic memory), psychiatric, metabolic, and socioeconomic measures as well as assessment of systemic health (with a focus on menopause via hormonal assays). This dataset will provide a unique resource for examining how brain organization and connectivity changes across typical aging, and how these differences relate to key characteristics of aging including alterations in hormonal status and declining memory and general cognition. A primary goal of the HCP-A is to make these data freely available to the scientific community, supported by the Connectome Coordination Facility (CCF) platform for data quality assurance, preprocessing and basic analysis, and shared via the NIMH Data Archive (NDA). Here we provide the rationale for our study design and sufficient details of the resource for scientists to plan future analyses of these data. A companion paper describes the related Human Connectome Project in Development (HCP-D, Somerville et al., 2018), and the image acquisition protocol common to both studies (Harms et al., 2018).

[PMID: 28802190 DOI: 10.1016/j.drugalcdep.2017.07.005] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Revised: 07/05/2017] [Accepted: 07/07/2017] [Indexed: 01/20/2023]
Abstract
BACKGROUND Little is known about the sequence of onsets in patients affected by comorbid alcohol use and bipolar disorder. This study examines the risk factors associated with their co-occurrence and order of onset. METHOD The demographic, clinical, and temperament characteristics as well as the course of illness were analyzed within our sample of 1090 DSM-IV bipolar I manic patients. Our sample was categorized according to the presence of comorbid alcohol use disorder and the sequence of onsets of bipolar and alcohol use disorders i.e., alcohol first (AUD-BD) and bipolar first (BD-AUD). RESULTS Regression analyses revealed that alcohol use disorder (52.5%) was associated with the male gender, additional substance use disorders, as well as an irritable and a hyperthymic temperament. The AUD-BD group (6.6%) was older than the BD-AUD group (45.8%) and showed higher rates of comorbid sedative use, organic, and anxiety disorders with higher levels of irritable temperament, and a bipolar subtype characterized by depressive polarity at onset. The BD-AUD group had high levels of hyperthymic temperament with higher rates of comorbid stimulant use disorder and a manic polarity at onset. CONCLUSIONS In the AUD-BD group, alcohol might have been used to reduce stress and tension caused by the presence of an irritable temperament as well as anxious and organic disorders, leading to first depressive episode. In the BD-AUD group, stimulant use might have triggered the first manic episode, and alcohol abuse result from mania severity.

Abstract
OBJECTIVE Alcohol-related blackouts (ARBs) are anterograde amnesias related to heavy alcohol intake seen in about 50% of drinkers. Although a major determinant of ARBs relates to blood alcohol concentrations, additional contributions come from genetic vulnerabilities and possible impacts of cannabis use disorders (CUDs). We evaluated relationships of genetics and cannabis use to latent class trajectories of ARBs in 829 subjects from the Collaborative Study of the Genetics of Alcoholism (COGA). METHOD The number of ARBs experienced every 2 years from subjects with average ages of 18 to 25 were entered into a latent class growth analysis in Mplus, and resulting class membership was evaluated in light of baseline characteristics, including CUDs. Correlations of number of ARBs across assessments were also compared for sibling pairs versus unrelated subjects. RESULTS Latent class growth analysis identified ARB-based Classes 1 (consistent low = 42.5%), 2 (moderate low = 28.3%), 3 (moderate high = 22.9%), and 4 (consistent high = 6.3%). A multinomial logistic regression analysis within latent class growth analysis revealed that baseline CUDs related most closely to Classes 3 and 4. The number of ARBs across time correlated .23 for sibling pairs and -.10 for unrelated subjects. CONCLUSIONS Baseline CUDs related to the most severe latent ARB course over time, even when considered along with other trajectory predictors, including baseline alcohol use disorders and maximum number of drinks. Data indicated significant roles for genetic factors for alcohol use disorder patterns over time. Future research is needed to improve understanding of how cannabis adds to the ARB risk and to find genes that contribute to risks for ARBs among drinkers.

Abstract
Mood and substance use disorders (SUDs) are mental conditions that are highly prevalent in the general population. Cooccurrence of major depression and SUD, also known as dual depression, is very common in the field of substance addiction. Sex differences are found in both major depression and SUD. This review, after presenting the state of the art of dual depression as regards prevalence, ethiopathologic mechanisms, and clinical aspects, is focused on dual depression in women. An overview of some potential factors associated with the sex gap in dual depression such as injecting, sexual risk behavior, intimate partner violence, and the reproductive cycle is presented.

Abstract
OBJECTIVE Although major depressive disorder (MDD) and heavy episodic drinking (HED, 4+/5+ drinks in a single sitting for women/men) are common among young adults in college, the relationship between the two remains unclear. This study examined the association between MDD and HED in this population, the effect of gender on this association, and whether comorbid MDD and heavy alcohol use are associated with higher rates of mental health treatment engagement. METHOD The study comprised 61,561 (65.3% female) undergraduate students who answered an online survey on depression, alcohol use, and treatment engagement in the past year. Hierarchical linear regressions examined the association between MDD and alcohol use (HED and peak blood alcohol concentration [pBAC]) and whether gender moderated these associations. Logistic regressions were then conducted to examine the influence of MDD, heavy alcohol use, and gender on treatment engagement. RESULTS Students with MDD reported more frequent HED and higher pBAC than did students without MDD; this was especially true for female students. Rates of treatment engagement were higher among women than men, among students with MDD than students without MDD, and among female students with HED than women without HED. CONCLUSIONS The presence of an association between MDD and heavy alcohol use suggests the need for systematic screenings of both conditions. Low rates of treatment engagement in college students with MDD and heavy alcohol use calls for the development of strategies to engage this high-risk group in treatment.

Abstract
During puberty, when young people are completing their education, transitioning into employment, and forming longer-term intimate relationships, a shift in emotional regulation and an increase in risky behaviour, including substance use, is seen. This Series paper considers the potential effects of alcohol, tobacco, and illicit drug use during this period on: social, psychological, and health outcomes in adolescence and young adulthood; role transitions, and later health and social outcomes of regular substance use initiated in adolescence; and the offspring of young people who use substances. We sourced consistent support for causal relations between substance use and outcomes and evidence of biological plausibility from different but complementary research designs. Many adverse health and social outcomes have been associated with different types of substance use. The major challenge lies in deciding which are causal. Furthermore, qualitatively different harms are associated with different substances, differences in life stage when these harms occur, and the quality of evidence for different substances and health outcomes varies substantially. The preponderance of evidence comes from a few high-income countries, thus whether the same social and health outcomes would occur in other countries and cultures is unclear. Nonetheless, the number of harms that are causally related to substance use in young people warrant high-quality research design interventions to prevent or ameliorate these harms.

Abstract
BACKGROUND Epidemiological studies and theory implicate drinking to cope (DTC) with anxiety as a potent moderator of the association between anxiety disorder (AnxD) and problematic alcohol use. However, the relevance of DTC to the treatment of alcohol use disorder (AUD) in those with a co-occurring AnxD has not been well studied. To address this, we examined whether DTC moderates the impact of two therapies: (1) a cognitive behavioral therapy (CBT) designed to reduce DTC and anxiety symptoms; (2) a progressive muscle relaxation training (PMRT) program designed to reduce anxiety symptoms only. METHODS Patients undergoing a standard AUD residential treatment with a co-occurring AnxD (N=218) were randomly assigned to also receive either the CBT or PMRT. DTC in the 30 days prior to treatment was measured using the Unpleasant Emotions subscale of the Inventory of Drinking Situations. RESULTS Confirming the predicted moderator model, the results indicated a significant interaction between treatment group and level of pre-treatment DTC behavior. Probing this interaction revealed that for those reporting more pre-treatment DTC behavior, 4-month alcohol outcomes were superior in the CBT group relative to the PMRT group. For those reporting less pre-treatment DTC behavior, however, 4-month alcohol outcomes were similar and relatively good in both treatment groups. CONCLUSIONS These findings establish a meaningful clinical distinction among those with co-occurring AUD-AnxD based on the degree to which the symptoms of the two disorders are functionally linked through DTC. Those whose co-occurring AUD-AnxD is more versus less strongly linked via DTC are especially likely to benefit from standard AUD treatment that is augmented by a brief CBT designed to disrupt this functional link.

Abstract
OBJECTIVE A person's pattern of heavier drinking often changes over time, especially during the early drinking years, and reflects complex relationships among a wide range of characteristics. Optimal understanding of the predictors of drinking during times of change might come from studies of trajectories of alcohol intake rather than cross-sectional evaluations. METHOD The patterns of maximum drinks per occasion were evaluated every 2 years between the average ages of 18 and 24 years for 833 subjects from the Collaborative Study on the Genetics of Alcoholism. Latent class growth analysis identified latent classes for the trajectories of maximum drinks, and then logistic regression analyses highlighted variables that best predicted class membership. RESULTS Four latent classes were found, including Class 1 (69%), with about 5 maximum drinks per occasion across time; Class 2 (15%), with about 9 drinks at baseline that increased to 18 across time; Class 3 (10%), who began with a maximum of 18 drinks per occasion but decreased to 9 over time; and Class 4 (6%), with a maximum of about 22 drinks across time. The most consistent predictors of higher drinking classes were female sex, a low baseline level of response to alcohol, externalizing characteristics, prior alcohol and tobacco use, and heavier drinking peers. CONCLUSIONS Four trajectory classes were observed and were best predicted by a combination of items that reflected demography, substance use, level of response and externalizing phenotypes, and baseline environment and attitudes.

Abstract
OBJECTIVE As part of the 75th anniversary edition of the Journal of Studies on Alcohol and Drugs, this article reviews research on the relationship between mental disorders and substance use disorders ("comorbidity") from 1940--the journal's inception--to the present. METHOD First, a survey of the titles and abstracts of all articles published in the journal was used to identify those articles pertaining to comorbidity. Seminal and representative works from this set of articles and a limited selection of articles from other journals were included in the review. RESULTS The early psychosocial research emphasized psychoanalytic formulations of alcohol use as a defensive symptom, which informed the early experimental research on the tension-reducing properties of alcohol. The "cognitive revolution," occurring in the 1970s, enabled an expansion of the tension-reduction theory to include a central role for mental processes (e.g., alcohol expectancies) in promoting drinking to cope with negative affectivity. The early clinical research characterized mental conditions commonly co-occurring with alcohol disorders and considered their etiological relationship to alcohol disorders. The "neo-Kraepelinian revolution" in psychiatry, which also occurred in the 1970s, infused the clinical comorbidity research with a more rigorous diagnostic technology and a range of biomedical research methodologies to study the mechanistic linkages of co-occurring disorders. CONCLUSIONS Although a substantial quantity of scientific information on comorbidity has accumulated over the past 75 years, a standard model(s) of comorbidity has yet to congeal. Barriers and opportunities related to achieving this important goal are discussed.

Abstract
BACKGROUND Alcohol and drug use disorders (AUDs and SUDs) and their combination are relatively common and often occur together. However, the relationships of potential early life correlates of alcohol and drug disorders to the combined diagnoses have rarely been evaluated in long-term prospective studies or in populations at high risk of one of these diagnoses but not the other. METHODS Data were analyzed from 397 males (half with an alcohol-dependent father) who had no AUDs or SUDs at age 20 and who were followed approximately every 5 years for 3 decades. Early life correlates and the course of AUDs, SUDs, and combined disorders were evaluated for 4 groups of subjects based on subsequent alcohol and/or drug diagnoses. RESULTS While the overall rates of the development of AUDs and SUDs were 41 and 21%, respectively, the rates of the second substance-related diagnosis were almost 2-fold higher for individuals who had the first condition. Among potential risk factors, scores for externalizing traits were elevated for men with AUDs, SUDs, and their combination, but a low level of response (low LR) to alcohol was associated only with the risk of AUDs, even when observed in the context of SUDs. The same earlier life characteristics that related to AUDs and to SUDs also related to the combination of these diagnoses in the same person. Finally, in this prospective study, subjects with both AUDs and SUDs had a more severe course than subjects with either condition alone. CONCLUSIONS This prospective evaluation of a group at high risk of AUDs confirmed the selective impact of the low LR on the risk of AUDs, the relationship of externalizing characteristics to both AUDs and SUDs and confirmed the more severe clinical course for both conditions when seen together.
