Lifetime comorbidity of DSM-IV mood and anxiety disorders and specific drug use disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

OBJECTIVE: To present nationally representative data on the lifetime prevalence and comorbidity of 8 specific drug use disorders, separately for abuse and dependence, and mood and anxiety disorders. METHOD: Data come from a representative sample (N=43,093) of the United States civilian, noninstitutional population 18 years and older. Diagnoses of mood, anxiety, and drug use disorders were based upon face-to-face personal interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version (AUDADIS-IV). RESULTS: Associations between specific mood and anxiety disorders and specific drug use disorders were virtually all positive and statistically significant (p<.05). In general, associations were greater for dependence than abuse, greater for mood than anxiety disorders, and in some instances stronger among women than men (p<.05). Large odds ratios also were observed for individuals with comorbid mood and anxiety disorders. CONCLUSION: The comorbidity between specific mood and anxiety disorders and specific drug use disorders is pervasive in the U.S. population. Findings suggest that comorbid psychiatric disorders may increase the risk of greater involvement in more serious illicit drug use disorders and that the greater comorbidity between mood and anxiety and drug use disorders among women may reflect greater deviance and psychopathology among drug-using women than men. Findings also suggest that drug abuse prevention and intervention efforts should address other psychiatric conditions. Further, definitions of drug use disorder phenotypes should give careful consideration to other psychiatric conditions as meaningful characteristics of case heterogeneity.

The epidemiology of DSM-IV panic disorder and agoraphobia in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

OBJECTIVE: To present nationally representative data on the prevalence, correlates, and comorbidity of DSM-IV panic disorder (PAN), including the differentiation between panic with agoraphobia (PDA) and without agoraphobia (PDWA) and agoraphobia without a history of panic disorder (AG). METHOD: The data were derived from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (N = 43,093). Prevalence, correlates, and comorbidity of PAN, PDA, and PDWA with Axis I and II disorders were determined. RESULTS: Prevalences of 12-month and lifetime PAN were 2.1% and 5.1%. Rates of 12-month and lifetime PDWA were 1.6% and 4.0%, exceeding those of 12-month (0.6%) and lifetime (1.1%) PDA. Rates of 12-month and lifetime AG were extremely low, 0.05% and 0.17%. Being female, Native American, middle-aged, widowed/ separated/divorced, and of low income increased risk, while being Asian, Hispanic, or black decreased risk for PAN, PDA, and PDWA. Individuals with PDA were more likely to seek treatment and had earlier ages at onset and first treatment, longer episodes, and more severe disability, impairment, panic symptomatology, and Axis I and II comorbidity than those with PDWA. CONCLUSION: PDA may be a more severe variant of PAN. Overrepresentation of PDA in treatment settings reflects increased treatment seeking and the severity of PDA relative to PDWA. The very low prevalence of AG leaves open questions about the meaning of the disorder as a distinct clinical entity as defined in the DSM-IV.

Prevalence, correlates, and comorbidity of nonmedical prescription drug use and drug use disorders in the United States: Results of the National Epidemiologic Survey on Alcohol and Related Conditions.

OBJECTIVE: To present national data on the prevalence, correlates, and comorbidity of nonmedical prescription drug use and drug use disorders for sedatives, tranquilizers, opioids, and amphetamines. METHOD: Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face nationally representative survey of 43,093 adults conducted during 2001 and 2002. RESULTS: Lifetime prevalences of nonmedical use of sedatives, tranquilizers, opioids, and amphetamines were 4.1%, 3.4%, 4.7%, and 4.7%, respectively. Corresponding rates of abuse and/or dependence on these substances were 1.1%, 1.0%, 1.4%, and 2.0%. The odds of nonmedical prescription drug use and drug use disorders were generally greater among men, Native Americans, young and middle-aged, those who were widowed/ separated/divorced or never married, and those residing in the West. Abuse/dependence liability was greatest for amphetamines, and nonmedical prescription drug use disorders were highly comorbid with other Axis I and II disorders. The majority of individuals with non-medical prescription drug use disorders never received treatment. CONCLUSIONS: Nonmedical prescription drug use and disorders are pervasive in the U.S. population and highly comorbid with other psychiatric disorders. Native Americans had significantly greater rates of nonmedical prescription drug use and drug use disorders, highlighting the need for culturally-sensitive prevention and intervention programs. Unprecedented comorbidity between nonmedical prescription drug use disorders and between nonmedical prescription drug use disorders and illicit drug use disorders suggests that the typical individual abusing or dependent on these drugs obtained them illegally, rather than through a physician. Amphetamines had the greatest abuse/dependence liability, and recent increases in the potency of illegally manufactured amphetamines may portend an epidemic in the youngest NESARC cohort.

The prevalence of drinking and driving in the United States, 2001-2002: results from the national epidemiological survey on alcohol and related conditions.

Traffic deaths and injuries are among the most frequent causes of deaths and disability worldwide. In the United States, the National Highway Transportation Safety Administration (NHTSA) reported that approximately 40% of all traffic fatalities were alcohol-related. Yet, information about the prevalence of drinking and driving behaviors of the U.S. general population is lacking. The purpose of this study was to examine the magnitude of driver-based (i.e., driving while drinking and driving after having too much to drink) and passenger-based (i.e., riding with a drinking driver and riding as a passenger while drinking) drinking and driving behaviors confronting contemporary America. The past-year prevalence data were stratified by major sociodemographic characteristics to identify important determinants of drinking and driving behaviors for further research. Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC, n=43,093). In 2001-2002 there were 23.4 million, or 11.3%, of American adults who reported engaging in at least one of the four driver- or passenger-based drinking and driving behaviors. The prevalences of passenger-based drinking and driving behaviors were generally greater than those of the driver-based measures. For all four drinking and driving behaviors, age was inversely associated with the risk and males were at greater risk with the associated male-to-female ratios of approximately 3.0. Our data also suggested that Native Americans, individuals who were widowed/separated/divorced or never married, and those with greater than a high school education were also at greater risks of all drinking and driving behaviors.

Prevalence, correlates, co-morbidity, and comparative disability of DSM-IV generalized anxiety disorder in the USA: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

BACKGROUND: This study addressed the prevalences, correlates, co-morbidity and disability of DSM-IV generalized anxiety disorder (GAD) and other psychiatric disorders in a large national survey of the general population, the National Institute on Alcohol Abuse and Alcoholism's (NIAAA) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). The study presents nationally representative data, for the first time, on prevalence, correlates, co-morbidity, and comparative disability of DSM-IV GAD. METHOD: Data are taken from a large (n=43093) representative sample of the adult USA population.R: Prevalences of 12-month and lifetime GAD were 2.1% and 4.1%. Being female, middle-aged, widowed/separated/divorced, and low income increased risk, while being Asian, Hispanic, or Black decreased risk. GAD was highly co-morbid with substance use, and other anxiety, mood, and personality disorders. Co-morbidity in GAD was not substantially greater than for most other Axis I and II disorders. Disability and impairment in pure GAD were equivalent to pure mood disorders, but significantly greater than in pure substance use, and other anxiety and personality disorders. Individuals co-morbid for GAD and each mood disorder were more disabled than those with pure forms of GAD or each mood disorder. When co-morbid with GAD, nicotine dependence and other anxiety and personality disorders were not associated with increased disability over that associated with pure GAD, but GAD did show increased disability over that due to each of these disorders in pure form.Conclusions. Associations between GAD and Axis I and II disorders were strong and significant, with variation among specific disorders. Results strongly support GAD as an independent disorder with significant impairment and disability.

The association between stress and drinking: modifying effects of gender and vulnerability.

AIMS: To assess the relationship between number and type of past-year stressful experiences and alcohol consumption, with a focus on how gender, poverty, and psychological vulnerability moderate this association. METHODS: Data from 26 946 US past-year drinkers 18 years of age and over, interviewed in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), were used to construct multivariate linear regression models predicting six measures of drinking pattern and volume. RESULTS: There was a consistent positive relationship between number of past-year stressors experienced and all measures of heavy drinking. Frequency of heavy (5+ drinks for men; 4+ drinks for women) drinking increased by 24% with each additional stressor reported by men and by 13% with each additional stressor reported by women. In contrast, the frequency of moderate drinking (<5 drinks for men; <4 drinks for women) decreased as stress levels increased. Job-related and legal sources of stress were more strongly associated with alcohol consumption than were social and health-related stress. Men showed a stronger association than women between the number of stressors and the most consumption measures; they also responded more strongly to the presence of any legal and job-related stress. Having an income below the poverty level intensified the effects of job-related stress, but having a mood or anxiety disorder did not affect any of the associations between stress and consumption. CONCLUSIONS: Stress does not so much lead individuals to drink more often as to substitute larger quantities of alcohol on the days when they do drink. Treatment and brief interventions aimed at problem drinkers might benefit from addressing the issue of tension alleviation and the development of alternative coping mechanisms.

Twelve-month prevalence and changes in driving after drinking: United States, 1991-1992 and 2001-2002.

BACKGROUND: Drinking and driving has been identified as one of the most important contributors of motor vehicle fatalities. This paper addressed the existing gap in our public health knowledge regarding the current prevalence of driving after drinking and how this has changed over the past decade. METHODS: Prevalence rates of drinking and driving in 2001-2002, and changes in those prevalence rates between 1991-1992 and 2001-2002 were examined in two large nationally representative surveys of the U.S. population. RESULTS: Overall, the prevalence of driving after drinking was 2.9% in 2001-2002 representing approximately six million U.S. adults. This rate was about three quarters of the rate observed in 1991-1992 (3.7%), reflecting a 22% reduction. Generally, the male-female differentials in the rate of driving after drinking decreased over the past decade. However, the sex ratios increased substantially for under-aged youth over the past decade, reflecting the sharp decrease in prevalence of driving after drinking among 18-20-year-old women. Constant and emerging subgroups at high risk for drinking and driving included Whites, Native Americans, males, under-aged young adults and 21-25-year-olds. CONCLUSIONS: The results of this study highlighted the need to continue to monitor prevalence and changes in driving after drinking. Results are discussed in the context of strengthening existing prevention and intervention efforts and developing new programs with the sociodemographic differentials observed in this study in mind.

Comorbidity between DSM-IV alcohol and specific drug use disorders in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

BACKGROUND: To date, there have been no published data on 12-month comorbidity of DSM-IV alcohol and drug use disorders in the general U.S. population. The purposes of the present study were to examine the prevalence and comorbidity of alcohol and specific drug use disorders, and to identify sociodemographic and psychopathologic correlates and treatment seeking among three groups of respondents: (1) those with alcohol use disorders only; (2) those with drug use disorders only; (3) those with comorbid alcohol and drug use disorders. METHODS: Information on 12-month alcohol and specific drug use disorders in the United States was derived from face-to-face interviews in the National Institute on Alcohol Abuse and Alcoholism's (NIAAA) 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC: n = 43,093). RESULTS: Prevalences were 7.35% for alcohol use disorders only, 0.90% for drug use disorder only and 1.10% for comorbid alcohol and drug use disorders. Sociodemographic and psychopathologic correlates of these three groups were quite different, with the drug use disorder and comorbid groups significantly more likely to be young, male, never married and of lower socioeconomic status than the alcohol use disorder only group. Associations between current alcohol use disorders and 25 specific drug use disorders were generally positive and statistically significant. The 12-month prevalence of treatment seeking significantly increased from 6.06% for those with an alcohol use disorder only to 15.63% for those with a drug use disorder only, and to 21.76% for those with comorbid alcohol and drug use disorders. CONCLUSIONS: This study provides detailed data on the homotypic comorbidity of alcohol use disorders and 25 different drug use disorders and confirms the high levels of association seen in previous studies based on lifetime measures. Implications of this study are discussed in terms of integrating alcohol and drug treatment services and refining prevention and intervention efforts.

Co-occurring DSM-IV drug abuse in DSM-IV drug dependence: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

The extent to which dependence occurs with or without abuse is important because of the potential for underestimation and biased estimates of drug dependence in surveys that rely on abuse as a screening method for dependence. The purpose of this paper was to present the prevalence of DSM-IV drug dependence with and without drug abuse in a nationally representative sample, as well as in subgroups defined by sex, age and race/ethnicity. Among all respondents with current drug dependence, 22.0% did not additionally meet criteria for abuse (19.5% among males and 27.8% among females). Current drug dependence without abuse was especially common among females age 45-64 (52.6% of all cases). Among those with lifetime diagnoses of drug dependence, a small proportion overall, 5.0% had no symptoms of abuse, with the highest proportion again found among females aged 45-64 (19.5% of all cases). The use of drug abuse as a screening method for drug dependence in large epidemiologic studies will differentially underestimate the prevalence of dependence by subgroup, affecting many types of research. Dependence with and without abuse may represent heterogeneous phenotypes for genetic and gene-environment research, which should be explored.

Psychopathology associated with drinking and alcohol use disorders in the college and general adult populations.

This paper examines the associations between past-year drinking status and the prevalence of 15 different past-year anxiety, mood and personality disorders, using a large (n = 43,093) nationally representative sample of the U.S. population. The prevalence of these disorders and their associations with drinking are compared for college students 18-29 years of age, other youth 18-29 years of age, and adults 30 years of age and older. After adjusting for sociodemographic characteristics and past-year tobacco and illicit drug use, only drinkers with alcohol dependence experienced an excess risk of a mood or anxiety disorder among college students 18-29 years of age, OR = 2.4. In contrast, the excess risk of any mood or anxiety disorder associated with drinking status among non-college youth varied from an OR of 1.8 for non-binge drinkers to 4.7 for drinkers with alcohol dependence. Among persons 30 years of age and older, the degree of excess risk was slightly lower but still higher than those for college students, OR = 1.5-3.8. Similarly, the excess odds of any personality disorder associated with drinking varied from 1.6 to 5.0 for the younger, non-college group and from 1.5 to 3.8 for the older adults, with no significant effect observed among college students. Factors that may help explain the weaker association of psychopathology and drinking in the college population include selectivity and greater availability of social and treatment resources that serve as alternatives to self-medicating the symptoms of psychological distress with alcohol.

Epidemiology of major depressive disorder: results from the National Epidemiologic Survey on Alcoholism and Related Conditions.

OBJECTIVE: To present nationally representative data on 12-month and lifetime prevalence, correlates, and comorbidity of DSM-IV major depressive disorder (MDD) among adults in the United States. DESIGN/SETTING/ PARTICIPANTS: Face-to-face survey of more than 43 000 adults aged 18 years and older residing in households and group quarters in the United States. MAIN OUTCOME MEASURES: Prevalence and associations of MDD with sociodemographic correlates and Axis I and II disorders. RESULTS: The prevalence of 12-month and lifetime DSM-IV MDD was 5.28% (95% confidence interval, 4.98-5.57) and 13.23% (95% confidence interval, 12.64-13.81), respectively. Being female; Native American; middle-aged; widowed, separated, or divorced; and low income increased risk, and being Asian, Hispanic, or black decreased risk (P<.05). Women were significantly more likely to receive treatment than men. Both current and lifetime MDD were significantly associated with other specific psychiatric disorders, notably substance dependence, panic and generalized anxiety disorder, and several personality disorders. CONCLUSIONS: This large survey suggests a higher prevalence of MDD in the US population than large-sample estimates from the 1980s and 1990s. The shift in highest lifetime risk from young to middle-aged adults is an important transformation in the distribution of MDD in the United States and specificity in risk for an age-period cohort. Associations between MDD and Axis I and II disorders were strong and significant, with variation within broad categories by specific diagnoses signaling the need for attention to the genetic and environmental reasons for such variation, as well as the implications for treatment response.

Co-occurrence of 12-month mood and anxiety disorders and personality disorders in the US: results from the national epidemiologic survey on alcohol and related conditions.

The objective of this study was to determine the prevalence and co-occurrence of DSM-IV personality disorders (PDs) among individuals with current DSM-IV mood and anxiety disorders in the US population and among individuals who sought treatment for such mood or anxiety disorders. Face-to-face interviews were conducted with 43,093 individuals, 18 years and older, in the National Institute on alcohol abuse and alcoholism's 2001-2002 National epidemiologic survey on alcohol and related conditions (NESARC). Odds ratios (ORs) were calculated to determine the prevalence and associations between current DSM-IV axis I and axis II disorders. Associations between mood, anxiety and PDs were all positive and statistically significant. Avoidant and dependent PDs were more strongly related to mood and anxiety disorders than other PDs. Associations between obsessive-compulsive PD and mood and anxiety disorders were significant, but much weaker. Paranoid and schizoid PDs were most strongly related to dysthymia, mania, panic disorder with agoraphobia, social phobia and generalized anxiety disorder, while histrionic and antisocial PDs were most strongly related to mania and panic disorder with agoraphobia. Results of this study highlight the need for further research on overlapping symptomatology, factors giving rise to the associations and the treatment implications of these disorders when comorbid.

Effectiveness of the derived Alcohol Use Disorders Identification Test (AUDIT-C) in screening for alcohol use disorders and risk drinking in the US general population.

BACKGROUND: The three consumption questions from the Alcohol Use Disorders Identification Test (AUDIT-C) are increasingly used as a screener for alcohol use disorders (AUDs) and risk drinking. METHODS: In a representative sample of US adults 18 years of age and older, AUDIT-C scores (derived from consumption questions embedded in a large national survey) were used to estimate sensitivity, specificity, and areas under receiver operator characteristic curves (AUROCs) for alcohol dependence, any AUD, and risk drinking. AUDs were defined according to DSM-IV criteria. For men, risk drinking was defined as consuming >14 drinks per week or >4 drinks in a single day at least once a month; for women, the weekly and daily limits were >7 drinks and >3 drinks, respectively. The derived AUDIT-C was evaluated among past-year drinkers (n = 26,946), within the total population (n = 43,093), in groups defined by age, sex, and race/ethnicity, and among pregnant women, persons attending an emergency room, and college students. RESULTS: For past-year drinkers, the AUROCs for the derived AUDIT-C were 0.887 for alcohol dependence, 0.860 for any AUD, and 0.966 for risk drinking. Scores were higher in the total population, 0.931, 0.917, and 0.981, respectively. The derived AUDIT-C performed slightly better in screening for dependence among women than men. Screening for risk drinking was better among men, probably because the third AUDIT-C question directly mirrors one of the definitions of risk drinking for men but not for women. Performance in pregnant women, past-year emergency room patients, and college students was on a par with performance in the general population. CONCLUSIONS: The derived AUDIT-C performs well in screening for AUDs and risk drinking. The use of variable cut points for men and women improves its sensitivity and specificity. Validation in a realistic screening situation, in which the AUDIT-C questions are asked as stand-alone and not embedded items, is a critical future step.

Patterns of DSM-IV alcohol abuse and dependence criteria among adolescents and adults: results from the 2001 National Household Survey on Drug Abuse.

BACKGROUND: Studies of the prevalence of DSM-IV alcohol use disorders (AUDs) in general population samples of adolescents and adults are rare. Comparisons of the prevalence of alcohol abuse and dependence in adolescent surveys with the prevalence in adult general population surveys are confounded by differences in survey design and measurement, thereby reducing their validity. The purpose of the present study was to examine the effects of age, sex, race/ethnicity, and drinking status on the prevalence of DSM-IV alcohol abuse and dependence (including diagnostic orphans) and associated diagnostic criteria among adolescents and adults aged 12-65 years in a single representative sample of the US population. METHODS: This study was based on data from the 2001 National Household Survey on Drug Abuse public use file. Of the 55,561 subjects in the survey, 33,576 (60.5%) reported alcohol use in the past year and provided information on DSM-IV AUD criteria. DSM-IV AUD criteria were assessed by questions related to specific symptoms occurring during the past 12 months. RESULTS: Overall, the most prevalent criteria of DSM-IV alcohol dependence were "tolerance" and "time spent obtaining alcohol, drinking, or getting over its effects." The most prevalent criterion of DSM-IV alcohol abuse was "hazardous use." The prevalence of alcohol abuse only and of dependence with and without abuse was highest among respondents aged 18-23 years, followed by respondents aged 12-17 years, and lowest among respondents aged 50 years and older. Among subgroups of current and heavier drinkers, differences between adolescents and young adults were less pronounced, especially among females. For each age group, the prevalence of alcohol abuse only was greater than the prevalence of dependence (with or without abuse). The abuse-to-dependence ratios also were generally consistent across age groups and slightly higher among males (2.1:1.0) than females (1.6:1.0). CONCLUSIONS: The higher prevalence for some dependence criteria among adolescents and young adults as measured in the present study may blur the distinction between symptom reports associated with the normative development of drinking patterns and clinically relevant aspects of DSM-IV alcohol dependence.

Quantifying the risks associated with exceeding recommended drinking limits.

BACKGROUND: Although daily and weekly drinking limits demonstrate strong sensitivity and specificity in identifying alcohol use disorders (AUDs), there are no descriptive data that present the risks associated with exceeding these limits in a format suitable for presentation to patients, students, and the general public. METHODS: Data collected in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions were used to estimate the risks of past-year DSM-IV alcohol abuse and dependence associated with various frequencies of exceeding daily drinking limits (no more than 4 drinks for men; no more than 3 drinks for women) in a nationally representative sample of 26,946 US drinkers 18 years of age and older. These risks were further categorized by whether weekly drinking limits (no more than 14 drinks for men; no more than 7 drinks for women) were exceeded and by maximum number of drinks consumed in the past year. RESULTS: The prevalence of alcohol dependence with abuse increased in a fairly linear fashion with frequency of exceeding daily drinking limits. The prevalence of dependence alone (no abuse) and abuse alone (no dependence) peaked among persons who exceeded the daily limits twice a week and then leveled off, because individuals became increasingly likely to have both disorders at higher frequencies. Exceeding the weekly limits generally increased the risks of both disorders after accounting for frequency of exceeding the daily limits, but not always to a significant extent. Likewise, maximum quantity of drinks consumed was positively associated with the risks of AUDs even after accounting for frequency of risk drinking. There were few gender differences in the risk of dependence after adjusting for frequency of exceeding daily drinking limits, but the risk of alcohol abuse remained greater among men. CONCLUSIONS: These data provide a useful tool for illustrating the broad range of risk of AUDs associated with exceeding recommended drinking limits, and they support the utility of the daily and weekly drinking limits in predicting AUDs.

Recovery from DSM-IV alcohol dependence: United States, 2001-2002.

AIMS: To investigate the prevalence and correlates of recovery from Diagnostic and Statistical Manual version IV (DSM-IV) alcohol dependence by examining the past-year status of individuals who met the criteria for prior-to-past-year (PPY) dependence. DESIGN: Cross-sectional, retrospective survey of a nationally representative sample of US adults 18 years of age and over (first wave of a planned longitudinal survey). METHODS: This analysis is based on data from the 2001-02 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), in which data were collected in personal interviews conducted with one randomly selected adult in each sample household. A subset of the NESARC sample (total n = 43 093), consisting of 4422 US adults 18 years of age and over classified with PPY DSM-IV alcohol dependence, were evaluated with respect to their past-year recovery status: past-year dependence, partial remission, full remission, asymptomatic risk drinking, abstinent recovery (AR) and non-abstinent recovery (NR). Correlates of past-year status were examined in bivariate analyses and using multivariate logistic regression models. FINDINGS: Of people classified with PPY alcohol dependence, 25.0% were still classified as dependent in the past year; 27.3% were classified as being in partial remission; 11.8% were asymptomatic risk drinkers who demonstrated a pattern of drinking that put them at risk of relapse; 17.7% were low-risk drinkers; and 18.2% were abstainers. Only 25.5% of people with PPY dependence ever received treatment. Being married was associated positively with the odds of both AR and NR, and ethanol intake was negatively associated with both. Severity of dependence increased the odds of AR but decreased the odds of NR. The odds of AR (but not NR) increased with age and female gender but were decreased by the presence of a personality disorder. Treatment history modified the effects of college attendance/graduation, age at onset and interval since onset on the odds of recovery. CONCLUSIONS: There is a substantial level of recovery from alcohol dependence. Information on factors associated with recovery may be useful in targeting appropriate treatment modalities.

Comorbidity of DSM-IV pathological gambling and other psychiatric disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

OBJECTIVE: To present nationally representative data on lifetime prevalence and comorbidity of pathological gambling with other psychiatric disorders and to evaluate sex differences in the strength of the comorbid associations. METHOD: Data were derived from a large national sample of the United States. Some 43,093 household and group quarters residents age 18 years and older participated in the 2001-2002 survey. Prevalence and associations of lifetime pathological gambling and other lifetime psychiatric disorders are presented. The diagnostic interview was the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. Fifteen symptom items operationalized the 10 pathological gambling criteria. RESULTS: The lifetime prevalence rate of pathological gambling was 0.42%. Almost three quarters (73.2%) of pathological gamblers had an alcohol use disorder, 38.1% had a drug use disorder, 60.4% had nicotine dependence, 49.6% had a mood disorder, 41.3% had an anxiety disorder, and 60.8% had a personality disorder. A large majority of the associations between pathological gambling and substance use, mood, anxiety, and personality disorders were overwhelmingly positive and significant (p < .05), even after controlling for sociodemographic and socioeconomic characteristics. Male sex, black race, divorced/separated/widowed marital status, middle age, and living in the West and Midwest were associated with increased risk for pathological gambling. Further, associations between alcohol dependence, any drug use disorder, drug abuse, nicotine dependence, major depressive episode, and generalized anxiety disorder and pathological gambling were stronger among women than men (p > .05). CONCLUSION: Pathological gambling is highly comorbid with substance use, mood, anxiety, and personality disorders, suggesting that treatment for one condition should involve assessment and possible concomitant treatment for comorbid conditions.

Prevalence, correlates, and comorbidity of DSM-IV antisocial personality syndromes and alcohol and specific drug use disorders in the United States: results from the national epidemiologic survey on alcohol and related conditions.

OBJECTIVE: The purpose of this study was to provide nationally representative data on the prevalence, sociodemographic correlates, and comorbidity of antisocial syndromes across alcohol and 8 specific drug use disorders, including sedative, tranquilizer, opiate, stimulant, hallucinogen, cannabis, cocaine, and inhalant/solvent abuse and dependence. METHOD: This study is based on a nationally representative sample of adults. Lifetime prevalences of antisocial syndromes were estimated and logistic regression analyses were used to examine associations between antisocial syndromes and sociodemographic characteristics and substance use disorders. Diagnoses were made according to the criteria of the DSM-IV using the National Institute on Alcohol Abuse and Alcoholism Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. RESULTS: The lifetime prevalences of antisocial personality disorder (APD), conduct disorder, and adult antisocial behavior were 3.6%, 1.1%, and 12.3%, respectively. Prevalences of alcohol use disorders and drug use disorders were 30.3% and 10.3%, respectively. In general, men and individuals who were younger, widowed/separated/divorced, of lower socioeconomic status, and living in urban areas or in the West were more likely to have antisocial syndromes. Native Americans were more likely and Asians and Hispanics were less likely to have APD and adult antisocial behavior. Virtually all of the associations between APD and adult antisocial behavior and specific substance use disorders were positive and statistically significant (p < .05). Significant associations between conduct disorder and substance use disorders were concentrated among women. CONCLUSION: Comorbidity of specific substance disorders with antisocial syndromes is very common in the U.S. population. Further work in many directions is indicated by the results of this study, including the factors that give rise to the associations and the treatment and prevention implications of these conditions when comorbid.
