Validity of the DSM-5 craving criterion for alcohol, tobacco, cannabis, cocaine, heroin, and non-prescription use of prescription painkillers (opioids).

BACKGROUND: Although the DSM-5 was adopted in 2013, the validity of the new substance use disorder (SUD) diagnosis and craving criterion has not been investigated systematically across substances. METHODS: Adults (N = 588) who engaged in binge drinking or illicit drug use and endorsed at least one DSM-5 SUD criterion were included. DSM-5 SUD criteria were assessed for alcohol, tobacco, cannabis, cocaine, heroin, and opioids. Craving was considered positive if "wanted to use so badly that could not think of anything else" (severe craving) or "felt a very strong desire or urge to use" (moderate craving) was endorsed. Baseline information on substance-related variables and psychopathology was collected, and electronic daily assessment queried substance use for the following 90 days. For each substance, logistic regression estimated the association between craving and validators, i.e. variables expected to be related to craving/SUD, and whether association with the validators differed for DSM-5 SUD diagnosed with craving as a criterion v. without. RESULTS: Across substances, craving was associated with most baseline validators (p values<0.05); neither moderate nor severe craving consistently showed greater associations. Baseline craving predicted subsequent use [odds ratios (OR): 4.2 (alcohol) - 234.3 (heroin); p's ⩽ 0.0001], with stronger associations for moderate than severe craving (p's < 0.05). Baseline DSM-5 SUD showed stronger associations with subsequent use when diagnosed with craving than without (p's < 0.05). CONCLUSION: The DSM-5 craving criterion as operationalized in this study is valid. Including craving improves the validity of DSM-5 SUD diagnoses, and clinical relevance, since craving may cause impaired control over use and development and maintenance of SUD.

Changing relationships between smoking and psychiatric disorders across twentieth century birth cohorts: clinical and research implications.

As the risks of tobacco use become recognized and smoking becomes stigmatized, new smokers may be increasingly driven to smoke by biological or genetic vulnerabilities rather than social desirability. Given that genetic risk for deviant proneness is shared across other psychiatric and addictive disorders, we predicted that as rates of smoking decreased through the latter half of the twentieth century, associations between smoking and psychopathology would increase. Participants (N=25 412) from a large US study-the National Epidemiologic Survey on Alcohol and Related Conditions, NESARC-were interviewed using the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV Version (AUDADIS-IV) and classified into one of five birth cohort decades (1940s to 1980s) and three smoking history (nonsmokers, never-dependent smokers and ever-dependent smokers) groups. We found that the prevalence of smoking decreased across the five birth cohorts, but associations of smoking with drug and AUDs, attention-deficit hyperactivity disorder, bipolar disorder and antisocial personality disorder, each increased monotonically in more recently born cohorts, even after adjusting for concurrent demographic and socioeconomic changes. For drug and AUDs, increases were observed among smokers both with and without a history of nicotine dependence; for other outcomes, increases were entirely driven by nicotine-dependent smokers. Findings suggest that smokers in more recent cohorts have disproportionately high psychiatric vulnerability, and may benefit from greater mental health screenings. Differentiating between casual and dependent smokers may further help prioritize those at greatest risk. Researchers should also be aware of potential variation in psychiatric comorbidity based on cohort of birth when defining groups of smokers, to minimize confounding.

Combined role of childhood maltreatment, family history, and gender in the risk for alcohol dependence.

BACKGROUND: Studies of the relationship between childhood maltreatment and alcohol dependence have not controlled comprehensively for potential confounding by co-occurring maltreatments and other childhood trauma, or determined whether parental history of alcohol disorders operates synergistically with gender and maltreatment to produce alcohol dependence. We addressed these issues using national data. Method Face-to-face surveys of 27 712 adult participants in a national survey. RESULTS: Childhood physical, emotional and sexual abuse, and physical neglect were associated with alcohol dependence (p<0.001), controlling for demographics, co-occurring maltreatments and other childhood trauma. Attributable proportions (APs) due to interaction between each maltreatment and parental history revealed significant synergistic relationships for physical abuse in the entire sample, and for sexual abuse and emotional neglect in women (APs, 0.21, 0.31, 0.26 respectively), indicating that the odds of alcohol dependence given both parental history and these maltreatments were significantly higher than the additive effect of each alone (p<0.05). CONCLUSIONS: Childhood maltreatments independently increased the risk of alcohol dependence. Importantly, results suggest a synergistic role of parental alcoholism: the effect of physical abuse on alcohol dependence may depend on parental history, while the effects of sexual abuse and emotional neglect may depend on parental history among women. Findings underscore the importance of early identification and prevention, particularly among those with a family history, and could guide genetic research and intervention development, e.g. programs to reduce the burden of childhood maltreatment may benefit from addressing the negative long-term effects of maltreatments, including potential alcohol problems, across a broad range of childhood environments.

Thought disorder in the meta-structure of psychopathology.

BACKGROUND: Dimensional models of co-morbidity have the potential to improve the conceptualization of mental disorders in research and clinical work, yet little is known about how relatively uncommon disorders may fit with more common disorders. The present study estimated the meta-structure of psychopathology in the US general population focusing on the placement of five under-studied disorders sharing features of thought disorder: paranoid, schizoid, avoidant and schizotypal personality disorders, and manic episodes as well as bipolar disorder. METHOD: Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions, a face-to-face interview of 34 653 non-institutionalized adults in the US general population. The meta-structure of 16 DSM-IV Axis I and Axis II psychiatric disorders, as assessed by the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM-IV version (AUDADIS-IV), was examined using exploratory and confirmatory factor analysis. RESULTS: We document an empirically derived thought disorder factor that is a subdomain of the internalizing dimension, characterized by schizoid, paranoid, schizotypal and avoidant personality disorders as well as manic episodes. Manic episodes exhibit notable associations with both the distress subdomain of the internalizing dimension as well as the thought disorder subdomain. The structure was replicated for bipolar disorder (I or II) in place of manic episodes. CONCLUSIONS: As our understanding of psychopathological meta-structure expands, incorporation of disorders characterized by detachment and psychoticism grows increasingly important. Disorders characterized by detachment and psychoticism may be well conceptualized, organized and measured as a subdimension of the internalizing spectrum of disorders. Manic episodes and bipolar disorder exhibit substantial co-morbidity across both distress and thought disorder domains of the internalizing dimension. Clinically, these results underscore the potential utility of conceptualizing patient treatment needs using an approach targeting psychopathological systems underlying meta-structural classification rubrics.

Alcohol-use disorder severity predicts first-incidence of depressive disorders.

BACKGROUND: Previous studies suggest that alcohol-use disorder severity, defined by the number of criteria met, provides a more informative phenotype than dichotomized DSM-IV diagnostic measures of alcohol use disorders. Therefore, this study examined whether alcohol-use disorder severity predicted first-incident depressive disorders, an association that has never been found for the presence or absence of an alcohol use disorder in the general population. METHOD: In a national sample of persons who had never experienced a major depressive disorder (MDD), dysthymia, manic or hypomanic episode (n=27 571), we examined whether a version of DSM-5 alcohol-use disorder severity (a count of three abuse and all seven dependence criteria) linearly predicted first-incident depressive disorders (MDD or dysthymia) after 3-year follow-up. Wald tests were used to assess whether more complicated models defined the relationship more accurately. RESULTS: First-incidence of depressive disorders varied across alcohol-use disorder severity and was 4.20% in persons meeting no alcohol-use disorder criteria versus 44.47% in persons meeting all 10 criteria. Alcohol-use disorder severity significantly predicted first-incidence of depressive disorders in a linear fashion (odds ratio 1.14, 95% CI 1.06-1.22), even after adjustment for sociodemographics, smoking status and predisposing factors for depressive disorders, such as general vulnerability factors, psychiatric co-morbidity and subthreshold depressive disorders. This linear model explained the relationship just as well as more complicated models. CONCLUSIONS: Alcohol-use disorder severity was a significant linear predictor of first-incident depressive disorders after 3-year follow-up and may be useful in identifying a high-risk group for depressive disorders that could be targeted by prevention strategies.

Borderline personality disorder co-morbidity: relationship to the internalizing-externalizing structure of common mental disorders.

BACKGROUND: Borderline personality disorder (BPD) shows high levels of co-morbidity with an array of psychiatric disorders. The meaning and causes of this co-morbidity are not fully understood. Our objective was to investigate and clarify the complex co-morbidity of BPD by integrating it into the structure of common mental disorders. METHOD: We conducted exploratory and confirmatory factor analyses on diagnostic interview data from a representative US population-based sample of 34 653 civilian, non-institutionalized individuals aged ≥18 years. We modeled the structure of lifetime DSM-IV diagnoses of BPD and antisocial personality disorder (ASPD), major depressive disorder, dysthymic disorder, panic disorder with agoraphobia, social phobia, specific phobia, generalized anxiety disorder, post-traumatic stress disorder, alcohol dependence, nicotine dependence, marijuana dependence, and any other drug dependence. RESULTS: In both women and men, the internalizing-externalizing structure of common mental disorders captured the co-morbidity among all disorders including BPD. Although BPD was unidimensional in terms of its symptoms, BPD as a disorder showed associations with both the distress subfactor of the internalizing dimension and the externalizing dimension. CONCLUSIONS: The complex patterns of co-morbidity observed with BPD represent connections to other disorders at the level of latent internalizing and externalizing dimensions. BPD is meaningfully connected with liabilities shared with common mental disorders, and these liability dimensions provide a beneficial focus for understanding the co-morbidity, etiology and treatment of BPD.

Alcohol craving and the dimensionality of alcohol disorders.

BACKGROUND: ICD-10 includes a craving criterion for alcohol dependence while DSM-IV does not. Little is known about whether craving fits with or improves the DSM-IV criteria set for alcohol-use disorders. METHOD: Data were derived from current drinkers (n=18 352) in the 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES), a nationally representative survey of US adults >17 years of age. The Alcohol Use Disorder and Associated Disabilities Interview Schedule was used to assess the eleven DSM-IV dependence and abuse criteria, and alcohol craving. Exploratory factor, item response theory, and regression analyses were used to evaluate the psychometric properties and concurrent validity of DSM-based alcohol disorder criteria with the addition of alcohol craving. RESULTS: The past 12-month prevalence of craving was 1.3%. Craving formed part of a unidimensional latent variable that included existing DSM-IV criteria. Craving demonstrated high severity on the alcohol-use disorder continuum, resulting in an improved dimensional model with greater discriminatory ability compared with current DSM-IV criteria. Correlates of the diagnosis did not change with the addition of craving, and past 12-month craving was associated with prior alcohol dependence, depression, and earlier age of alcohol disorder onset among those with current DSM-IV alcohol dependence. CONCLUSIONS: The addition of craving to the existing DSM-IV criteria yields a continuous measure that better differentiates individuals with and without alcohol problems along the alcohol-use disorder continuum. Few individuals are newly diagnosed with alcohol dependence given the addition of craving, indicating construct validity but redundancy with existing criteria.

Social anxiety disorder and alcohol use disorder co-morbidity in the National Epidemiologic Survey on Alcohol and Related Conditions.

BACKGROUND: To assess the prevalence and clinical impact of co-morbid social anxiety disorder (SAD) and alcohol use disorders (AUD, i.e. alcohol abuse and alcohol dependence) in a nationally representative sample of adults in the United States. METHOD: Data came from a large representative sample of the US population. Face-to-face interviews of 43093 adults residing in households were conducted during 2001-2002. Diagnoses of mood, anxiety, alcohol and drug use disorders and personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV version. RESULTS: Lifetime prevalence of co-morbid AUD and SAD in the general population was 2.4%. SAD was associated with significantly increased rates of alcohol dependence [odds ratio (OR) 2.8] and alcohol abuse (OR 1.2). Among respondents with alcohol dependence, SAD was associated with significantly more mood, anxiety, psychotic and personality disorders. Among respondents with SAD, alcohol dependence and abuse were most strongly associated with more substance use disorders, pathological gambling and antisocial personality disorders. SAD occurred before alcohol dependence in 79.7% of co-morbid cases, but co-morbidity status did not influence age of onset for either disorder. Co-morbid SAD was associated with increased severity of alcohol dependence and abuse. Respondents with co-morbid SAD and alcohol dependence or abuse reported low rates of treatment-seeking. CONCLUSIONS: Co-morbid lifetime AUD and SAD is a prevalent dual diagnosis, associated with substantial rates of additional co-morbidity, but remaining largely untreated. Future research should clarify the etiology of this co-morbid presentation to better identify effective means of intervention.

Suicidal ideation and suicide attempts in the United States: 1991-1992 and 2001-2002.

The aim of the study is to compare the prevalence of suicidal ideation and attempts in the United States in 1991-1992 and 2001-2002, and identify sociodemographic groups at increased risk for suicidal ideation and attempts. Data were drawn from the National Institute on Alcohol Abuse and Alcoholism 1991-1992 National Longitudinal Alcohol Epidemiologic Survey (n=42,862) and the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (n=43,093), two nationally representative household surveys of non-institutionalized civilians aged 18 years and older, residing in the United States. The lifetime prevalence of suicide attempts remained unchanged in the United States between 1991-1992 and 2001-2002. Specific groups, namely 18- to 24-year-old white and black women, 25- to 44-year-old white women and 45- to 64-year-old Native American men were identified as being at high risk for suicide attempts. Despite prevention and treatment efforts, the lifetime prevalence of suicide attempts remains unchanged. Given the morbidity and mortality associated with suicide attempts, urgent action is needed to decrease the prevalence of suicide attempts in the United States.

Disordered gambling among racial and ethnic groups in the US: results from the national epidemiologic survey on alcohol and related conditions.

INTRODUCTION: Prior research suggests that racial minority groups in the United States are more vulnerable to develop a gambling disorder than whites. However, no national survey on gambling disorders exists that has focused on ethnic differences. METHODS: Analyses of this study were based on the National Epidemiologic Survey on Alcohol and Related Conditions, a large (N=43,093) nationally representative survey of the adult (> or =18 years of age) population residing in households during 2001-2002 period. Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision diagnoses of pathological gambling, mood, anxiety, drug use, and personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. RESULTS: Prevalence rates of disordered gambling among blacks (2.2%) and Native/Asian Americans (2.3%) were higher than that of whites (1.2%). Demographic characteristics and psychiatric comorbidity differed among Hispanic, black, and white disordered gamblers. However, all racial and ethnic groups evidenced similarities with respect to symptom patterns, time course, and treatment seeking for pathological gambling. CONCLUSION: The prevalence of disordered gambling, but not its onset or course of symptoms, varies by racial and ethnic group. These varying prevalence rates may reflect, at least in part, cultural differences in gambling and its acceptability and accessibility. These data may inform the need for targeted prevention strategies for high-risk racial and ethnic groups.

A low-cost, sustainable intervention for drinking reduction in the HIV primary care setting.

Excess drinking poses multiple substantial health risks to HIV-infected individuals. However, no published intervention studies have focused on drinking reduction as the main outcome in HIV primary care patients. An intervention in this setting must place minimal demands on pressured staff and resources. This pilot study tested such an intervention, which consisted of brief Motivational Interviewing (MI) and HealthCall, an automated daily telephone self-monitoring system based on Interactive Voice Response (IVR), designed to extend and enhance the effects of brief MI. Thirty-one patients entered the study, received a 30-minute MI and were instructed in daily use of the IVR system. They received graphical feedback on their daily drinking from the HealthCall database after 30 days. A statistically significant decrease in drinking was found over time, both as reported in daily IVR calls (beta = - 0.01, se 0.01, p=.03) and in follow-up interviews (beta = - 0.04, se 0.12, p=.02) at 60 days. The proportion of daily calls made supported the feasibility of the intervention. The results indicate that HealthCall is acceptable to a disadvantaged HIV patient population, and preliminary data support the efficacy of this intervention in reducing harmful drinking among HIV primary care patients.

Substance Dependence Severity Scale: reliability and validity for ICD-10 substance use disorders.

The Substance Dependence Severity Scale (SDSS) is a semistructured interview that assesses the severity of the DSM-IV diagnoses of dependence and abuse and the ICD-10 diagnoses of substance dependence and harmful use across a wide range of substances. Previous research has demonstrated that the SDSS' DSM-IV dependence scales are reliable and valid indicators of diagnostic severity. However, the ICD-10 scales have not been psychometrically tested. This study investigated the test-retest reliability, internal consistency, diagnostic concordance, and concurrent validity of the SDSS' ICD-10 dependence and harmful use scales in 180 (112 male and 68 female) treated substance users. Test-retest reliabilities for the ICD-10 dependence scales ranged from good to excellent for alcohol, cocaine, heroin, and cannabis. Test-retest reliabilities for the SDSS' ICD-10 harmful use scales were in the good range for alcohol, cocaine, and heroin and the poor to fair range for cannabis. Internal consistency, diagnostic concordance, and concurrent validity results were comparable to the test-retest findings. These results support the use of the SDSS for assessing the severity of the ICD-10 dependence and harmful use diagnoses.

Reliability and discriminant validity of the Type I/II and Type A/B alcoholic subtype classifications in untreated problem drinkers: a test of the Apollonian--Dionysian hypothesis.

The present study tested the hypothesis that there are two broad groups of problem drinkers: the Apollonian-Dionysian distinction. Apollonian drinkers are defined by a later onset of alcohol problems, a slower developmental course, and less problem severity. Dionysian drinkers are defined by more severe alcohol problems, an earlier onset, and worse prognosis. The discriminant validity and classification agreement of five operations of the Apollonian-Dionysian model were tested in a general population (n=8643) and community sample (n=664). A kappa-means cluster analysis supported the Apollonian-Dionysian distinction. Dionysian problem drinkers were more likely to be males, report greater alcohol consumption, more alcohol related antisocial behavior, have a current DSM-IV alcohol dependence diagnosis, and comorbid depression. Apollonian problem drinkers were more prevalent in the general population and reported less severe drinking problems. Classification agreement was stronger for subtype models that incorporate dimensions of alcohol use and/or the frequency of negative consequences. Babor's Type A-Type B model demonstrated the strongest reliability and consistency over time.

Substance Dependence Severity Scale (SDSS): reliability and validity of a clinician-administered interview for DSM-IV substance use disorders.

No existing diagnostic interview assesses severity of dependence based on DSM-IV criteria across a range of substances. The Substance Dependence Severity Scale (SDSS) was designed to serve this purpose, consisting of substance-specific scales of both severity and frequency of DSM-IV criteria. This study investigated the reliability and validity of the SDSS. The test-retest reliability of the SDSS in 175 (112 male and 63 female) treated substance users ranged from good to excellent for alcohol, cocaine, heroin and sedatives (interclass correlation coefficients (ICCs)=0.75-0.88 for severity, 0.67-0.85 for frequency). Results for cannabis were lower, ranging from fair to good (ICCs=0.50-0.62). Results for joint rating and internal consistency reliability were comparable to test-retest findings. In addition to indicators of concurrent validity, scale applications are presented and discussed.

Concurrent and predictive validity of the Substance Dependence Severity Scale (SDSS).

This study investigated the concurrent and predictive validity of the Substance Dependence Severity Scale (SDSS), a clinician-administered interview designed to assess the severity and frequency of DSM-IV dependence symptoms for a range of substances. A total of 172 (107 males and 66 females) treated substance users participated in the study. Of those, 89% (n=153) received at least one follow-up interview within 1-6 months of an initial assessment. For alcohol, cocaine and heroin, convergent and discriminant validity was supported by significant relationships between SDSS scores at baseline and other baseline measures of substance use consequences, such as the Addiction Severity Index (ASI), as well as significant relationships between SDSS change scores from baseline to follow-up and change scores of other measures of consequences. SDSS scores were significantly associated with time to first post treatment use of alcohol, cocaine and heroin, although the nature of the associations was complex. Scale applications and areas for further study are discussed.

Relationships between obesity and DSM-IV major depressive disorder, suicide ideation, and suicide attempts: results from a general population study.

OBJECTIVES: This study sought to test the relationships between relative body weight and clinical depression, suicide ideation, and suicide attempts in an adult US general population sample. METHODS: Respondents were 40,086 African American and White participants interviewed in a national survey. Outcome measures were past-year major depression, suicide ideation, and suicide attempts diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. The primary predictor was relative body weight, treated both continuously (i.e., body mass index [BMI]) and categorically in logistic regression analyses. Covariates included age, income and education, disease status, and drug and alcohol use. RESULTS: Relative body weight was associated with major depression, suicide attempts, and suicide ideation, although relationships were different for men and women. Among women, increased BMI was associated with both major depression and suicide ideation. Among men, lower BMI was associated with major depression, suicide attempts, and suicide ideation. There were no racial differences. CONCLUSIONS: Differences in BMI, or weight status, were associated with the probability of past-year major depression, suicide attempts, and suicide ideation. Longitudinal studies are needed to differentiate the causal pathways and mechanisms linking physical and psychiatric conditions.

When acute-stage psychosis and substance use co-occur: differentiating substance-induced and primary psychotic disorders.

Substances such as alcohol, cocaine, amphetamine, and cannabis can produce psychotic reactions in individuals who are otherwise free of serious mental illness. However, persons with primary psychotic disorders, such as schizophrenia and bipolar disorder, who use these substances often present for treatment with signs and symptoms similar to those whose psychosis resulted from the use of drugs alone. While it is often difficult to distinguish substance-induced from primary psychoses, especially early in the course of treatment, this differential diagnosis has important implications for treatment planning. To help clinicians distinguish these two types of presentations, the authors first review the types of psychotic symptoms that can co-occur with substance use. They discuss the prevalence and patterns of substance use that have been found in patients with schizophrenia and other primary psychotic disorders and review the negative outcomes associated with substance use in this population. The prevalence of and types of symptoms and problems associated with psychotic symptoms that occur as a result of substance use alone are also reviewed. The authors describe assessment procedures for differentiating substance-induced and primary psychotic disorders. They stress the importance of accurately establishing the temporal relationship between the substance use and the onset and continuation of psychotic symptoms in making a differential diagnosis, as well as the importance of being familiar with the types of psychological symptoms that can occur with specific substances. The authors review the utility and limitations of a number of diagnostic instruments for assessing patients with co-occurring psychosis and substance use problems, including The Addiction Severity Index, The Michigan Alcohol Screening Test, and diagnostic interviews such as the Schedule for Affective Disorders and Schizophrenia and the Structured Clinical Interview for DSM. They then discuss the Psychiatric Research Interview for Substance and Mental Disorders (PRISM), an instrument that has been developed to address the lack of a diagnostic interview that is suitable for assessing the comorbidity of substance use and psychiatric disorders. The article concludes with a discussion of the importance of an appropriate match between diagnosis and treatment and the current state of our knowledge concerning the most appropriate types of treatment interventions for patients with substance-induced psychosis and those with dual diagnoses.

Drinking to cope with negative affect and DSM-IV alcohol use disorders: a test of three alternative explanations.

OBJECTIVE: Previous studies of drinking motives have demonstrated greater levels of drinking to cope with negative affect among problem drinkers relative to nonproblem drinkers. These findings suggest that the use of alcohol to cope with negative affect may place individuals at greater risk for the development of alcohol problems. However, several alternative explanations exist, each with different intervention implications. This study evaluated three alternative explanations or models: risk-factor, generalizing, and epiphenomena. A cross-sectional design was used to compare levels of self-reported drinking to cope with negative affect between individuals who had current DSM-IV alcohol use disorders and those who did not. METHOD: Participants consisted of a sample of community residents (N = 777, 55% men). All participants completed an in-person structured psychiatric interview and a self-report questionnaire assessing alcohol use, drinking motives, depressive affect, and negative alcohol consequences. RESULTS: Linear regression models yielded significant differences in mean drinking to cope with negative affect scores between participants with a DSM-IV alcohol dependence diagnosis and participants with no diagnosis. These differences remained after controlling for depressive affect and frequency of negative alcohol consequences in three of the four adjusted comparisons. No significant differences in adjusted mean drinking to cope with negative affect scores were demonstrated between subjects with a DSM-IV alcohol abuse diagnosis and those with no diagnosis. CONCLUSIONS: The DSM-IV alcohol dependence and no-diagnosis comparisons were most consistent with the predictions of a risk-factor model. These results provide further evidence that drinking to cope with negative affect may have an etiological role in development of alcohol dependence.

Suicidal ideation among the United States drinking population: results from the National Longitudinal Alcohol Epidemiologic Survey.

OBJECTIVE: Data from a national representative sample of adults was used to identify major risk factors of suicidal ideation among the U.S. drinking population. METHOD: Data from a sample of 18,352 current drinkers, 18 years of age and older, were analyzed by means of multiple logistic regression analysis. In these analyses, multivariate associations were examined between risk factors for suicidal ideation and the occurrence of suicidal ideation. RESULTS: For men and women, past year major depression and alcohol dependence were identified as risk factors of suicidal ideation, with major depression having the more sizable impact. Suicidal ideation was increased among men with a past alcohol use disorder, and elevated among women who had used drugs nonmedically and developed a drug use disorder during the past year. The occurrence of a recent physical illness and lifetime treatment for major depression among men and women increased the risk of suicidal ideation, while marriage was protective against ideation for both sexes. Unemployment and having a family history of alcoholism increased the risk of suicidal ideation among men, but not women. CONCLUSIONS: Major findings are discussed in terms of the impact of severity versus chronicity of psychopathology on suicidal ideation, gender roles and differential engagement in suicidal ideation, and the recognition and treatment of major depression as the single most important intervention in reducing suicidal behavior.

Concordance between ICD-10 alcohol and drug use disorder criteria and diagnoses as measured by the AUDADIS-ADR, CIDI and SCAN: results of a cross-national study.

Agreement between the AUDADIS-ADR, CIDI and SCAN in case identification for ICD-10 alcohol and drug use disorders and diagnostic criteria was investigated in three countries, Luxembourg, Greece and the US. Overall, agreement for ICD-10 dependence diagnoses between the three instruments was fair to good for alcohol, opioids and cocaine, but generally lower for dependence diagnoses for other substance. In contrast, concordance between instruments for harmful use diagnoses was extremely poor for all substances. Implications of these major findings are discussed in terms of the relationship between prevalence, reliability and concordance and indications and cautions regarding cross-instrument comparisons.
