Toward DSM-V: an item response theory analysis of the diagnostic process for DSM-IV alcohol abuse and dependence in adolescents

ObjectiveItem response theory analyses were used to examine alcohol abuse and dependence symptoms and diagnoses in adolescents. Previous research suggests that the DSM-IV alcohol use disorder (AUD) symptoms in adolescents may be characterized by a single dimension. The present study extends prior research with a larger and more comprehensive sample and an examination of an alternative diagnostic algorithm for AUDs.MethodApproximately 5,587 adolescents between the ages of 12 and 18 years from adjudicated, clinical, and community samples were administered structured clinical interviews. Analyses were conducted to examine the severity of alcohol abuse and dependence symptoms and the severity of alcohol use problems (AUDs) within the diagnostic categories created by the DSM-IV.ResultsAlthough the DSM-IV diagnostic categories differ in severity of AUDs, there is substantial overlap and inconsistency in AUD severity of persons across these categories. Item Response Theory-based AUD severity estimates suggest that many persons diagnosed with abuse have AUD severity greater than persons with dependence. Similarly, many persons who endorse some symptoms but do not quality for a diagnosis (i.e., diagnostic orphans) have more severe AUDs that persons with an abuse diagnosis. Additionally, two dependence items, “tolerance” and “larger/longer,” show differences in severity between samples.ConclusionsThe distinction between DSM-IV abuse and dependence based on severity can be improved using an alternative diagnostic algorithm that considers all of the alcohol abuse and dependence symptoms conjointly.     

Craving and withdrawal as core symptoms of alcohol dependence

There is ongoing debate regarding the validity of the distinction of alcohol abuse and dependence, the distinction between normality and alcohol abuse, and the absence of craving in the DSM-IV classification of alcohol use disorders. In this study, we examine the discriminant validity of the DSM-IV alcohol use disorder diagnoses in three different populations (98 patients from an alcohol treatment service, 68 nontreatment-seeking heavy drinkers, and 75 psychiatric outpatients). We compare the results of the DSM-IV classification with an alternative classification that requires craving and withdrawal for the diagnosis of dependence and at least two DSM-IV abuse-dependence symptoms for the diagnosis of abuse: the Craving Withdrawal Model (CWM). Although the total prevalence of any alcohol use disorder did not differ between DSM-IV and CWM, the distinction between normality and abuse and between abuse and dependence was better for the CWM categories.     

The 5-year clinical course of high-functioning men with DSM-IV alcohol abuse or dependence

OBJECTIVE: One goal of diagnostic criteria is to predict the course of clinically relevant future problems. This study evaluated the ability of the DSM-IV categories of alcohol abuse and alcohol dependence to predict the onset and cessation of the 11 DSM-IV abuse/dependence criterion items. METHOD: The DSM-IV categorical approach was used to determine alcohol diagnoses for 435 highly educated young adult men, who constituted 97.3% of the 447 men appropriate for this study. Structured face-to-face follow-up interviews were administered 5 years later. RESULTS: At the beginning of the study, 14.5% (N=63) of the subjects were alcohol dependent, 18.2% (N=79) reported alcohol abuse, and 67.4% (N=293) carried no alcohol diagnosis. Across these three diagnostic groups, 68.3%, 46.8%, and 15.4%, respectively, experienced at least one of the 11 DSM-IV abuse/dependence criterion items over the next 5 years. Only 11.4% of those who reported alcohol abuse went on to develop alcohol dependence. In addition to their diagnosis, characteristics that predicted subsequent problems with alcohol included a family history of alcoholism, higher levels of alcohol intake and a greater number of alcohol problems in the 10 years preceding the diagnosis, and a history of drug use. CONCLUSIONS: Even in this highly educated and high-functioning group of men, alcohol abuse and dependence predicted the onset and cessation of alcohol-related problems.     

Prevalence of alcohol consumption, abuse and dependence in a country with high per capita consumption: findings from the German TACOS study

  Background: The aim of the Transitions in Alcohol Consumption and Smoking (TACOS) project is to investigate substance use and use disorders in the adult general population in a region of the under-researched north of Germany, focussing on smoking and alcohol consumption. In this study, the design and quality assurance provisions of the baseline cross-section of the longitudinal project are described. Prevalence rates of alcohol use disorders, consumption pattern, and the nature of their association are also analysed with regard to preventive strategies. Method: A random sample of 4075 participants, aged 18 to 64 and drawn from residents registration office files, was interviewed with a DSM-IV adapted version of WHO CIDI. Fieldwork resulted in a response rate of 70.2% and an unbiased database with regard to demographic characteristics. Results: Low lifetime prevalence of alcohol use disorders (4.5% abuse, 3.8% dependence) and hazardous consumption (13.2% lifetime; 6.0% 12-month) was found compared to southern regions of Germany and US American data. In contrast, we found a comparatively high percentage of moderate alcohol uses. Male subjects are more affected by lifetime alcohol use disorders (abuse OR 8.3, 95% CI 5.3–13.2; dependence OR 4.3, 95% CI 2.8–6.4). The association between alcohol use disorders and alcohol consumption pattern revealed a weaker relation for alcohol abuse compared to dependence. Conclusion: National and regional drinking habits and norms have to be considered as a significant source of variance, supporting the need for European epidemiological research on substance use in addition to US American activities, and emphasising the advantages of community-based preventive measures. An evaluation of public recommendations for safe limits of alcohol consumption and prevention targets referring to average consumption is indicated. There is also a need for a clear distinction between alcohol abuse and dependence. Accepted: 27 October 2000     

Parenting Styles and Psychiatric Profile of Parents of Adult Substance Use Disorder Patients: Cross-sectional Study

The purpose of this Lebanese, cross-sectional, multi-centric study is to examine the prevalence of psychiatric disorders among adult patients with substance use disorder and their parents along with the predominant parenting style. A total of 100 patients suffering from a substance use disorder, and their parents (N = 127) were administered the translated Arabic version of the MINI to diagnose lifetime psychiatric disorders. The Parental Authority Questionnaire (PAQ) in its translated validated Arabic version was filled by patients to detect the predominant parenting style. The least common parenting style reported was authoritative (25%). The parents’ prevalence of nicotine dependence, alcohol abuse and dependence, and illicit substance abuse and dependence were considerably higher than the general population. Mood and anxiety disorders were more prevalent among patients and their parents compared to the Lebanese general population. In the bivariate analysis, no significant association was found between the perceived parenting style (authoritative and non-authoritative) and parents’ economic (p = 0.545) and civil status (p = 0.231), patient’s gender (p = 0.390), birth order (p = 0.084), and parents’ and offspring psychiatric disorder. Hence, an underlying genetic and environmental mechanism could potentially explain our findings rather than a rearing problem; however, further studies with larger sample size are needed to confirm this hypothesis.

     

The differential impact of risk factors on illicit drug involvement in females

AbstractBackground Initiation of drug use and progression to abuse/dependence involve complex pathways. Potential risk factors may correlate with initiation or progression or both. Are there risk factors that associate with illicit drug use or illicit drug abuse/dependence? Is the magnitude of the association the same for use and abuse/dependence? Does this pattern of association differ across categories of drugs?Methods We used data from female-female adult twins to assess the association of 26 putative risk factors with use and abuse/dependence of six illicit psychoactive drugs. Drug involvement was represented by independent dichotomous outcomes and by a single ordinal variable. Odds ratios were obtained by logistic regression and a continuation ratio was used to test the magnitude of association.Results Factors associate in similar patterns with different drug categories. Some associated factors interact only with initiation while others relate with both stages. There is a stronger association of significant socio-demographic factors with drug use while the psychiatric diagnoses are more strongly associated with progression to abuse/dependence.Conclusions Risk factors may be use-specific, abuse/dependence-specific or common to use and abuse/dependence. The trend of associations is similar across different illicit drugs. This suggests complex, interacting pathways that determine drug habits in individuals. These results are hypothesis-generating and future studies of causal relationships may draw from the outcomes presented in these analyses.     

A Norwegian psychiatric epidemiological study.

OBJECTIVE: This study reports results of a large-scale epidemiological investigation of the prevalence of mental disorder in Oslo. METHOD: A random sample of Oslo residents age 18-65 years was drawn from the Norwegian National Population Register. A total of 2,066 subjects, 57.5% of the original sample, were interviewed with the Composite International Diagnostic Interview in 1994-1997. The mean age of the interviewed subjects was 39.3 years. RESULTS: The 12-month prevalence of all mental disorders was 32.8%, and the lifetime prevalence was 52.4%. Alcohol abuse/dependence and major depression had the highest lifetime prevalence and 12-month prevalences. All mental disorders were more prevalent in women than in men, with the exception of alcohol and drug abuse/dependence. Severe psychopathology (e.g., three or more diagnoses) was found in 14%-15% of the respondents. The lifetime and 12-month prevalences for all diagnostic categories except drug abuse/dependence were similar to those found in the United States Comorbidity Survey. CONCLUSIONS: Epidemiological data for Oslo show that the lifetime and 12-month prevalences of mental disorder are quite high, with alcohol abuse/dependence and major depression particularly frequent. The rates for women are higher than those for men for all diagnostic categories, except for alcohol and drug abuse/dependence.     

The impact of alcohol and illicit drugs on people with psychosis: The second Australian national survey of psychosis

Objective: To provide the most up-to-date prevalence estimates of alcohol and illicit drug use among individuals with psychosis in Australia, and explore correlates associated with a lifetime diagnosis of both alcohol abuse/dependence and cannabis abuse/dependence. Method: This paper uses data from the Survey of High Impact Psychosis (SHIP), conducted as a follow-up to the first Australian National Low Prevalence (Psychotic) Disorders Study (1997-1998). The SHIP was a national study, carried out across five states, in which a sample of 1825 individuals was recruited through a two-phase sampling framework. Results: Alcohol and illicit drug use was highly prevalent for the entire sample. There were few significant differences in the prevalence or frequency of use across the diagnostic categories examined. Substantial increases in substance abuse/dependence were noted since the 1997-1998 survey (51% diagnosed with alcohol abuse/dependence, 51% with cannabis abuse/dependence and 32% with other illicit drug abuse/dependence, compared to 28%, 23% and 12% respectively, in the 1997-1998 survey by Kavanagh et al., 2004). Factors significantly associated with both lifetime alcohol and cannabis dependence included male gender, younger age, single marital status, lower educational attainment, shorter duration of illness, lifetime presence of hallucinations, higher negative syndrome score and lower body mass index (BMI). A number of other factors were found to be differentially associated with either lifetime alcohol or cannabis dependence. Conclusions: The use of alcohol and illicit substances is common among people with a psychotic illness, with a concerning upward trend in rates of substance abuse/dependence since the 1997-1998 survey. Clinicians should be aware of the potential impact of concurrent substance use and provide integrated treatment for individuals presenting with psychotic illnesses. More research and investment in new intervention programs is required.     

Lifetime prevalence of specific mental disorders among people born in Iceland in 1931

The lifetime prevalence rates are presented for mental disorders in a random sample of people born in Iceland in 1931, interviewed at the age of 55-57 years. The diagnoses are made according to DSM-III, on the basis of the National Institute of Mental Health's diagnostic Interview Schedule (NIMH-DIS) used by trained lay interviewers. The most common diagnoses were alcohol abuse and dependence, generalized anxiety disorder, phobic disorders, dysthymic disorder and major depressive episode. Disorders more common in men were antisocial personality, alcohol abuse and alcohol dependence. Disorders more common among women were major depressive episode and generalized anxiety disorder. Alcohol abuse was more prevalent among those living in rural areas, but dependence was more prevalent in the urban area, where panic disorder is also more frequent. Widowed, separated and divorced people had most of the highest prevalences: tobacco-use disorder, alcohol abuse and dependence, dysthymia and generalized anxiety disorder. Except for a very high rate of alcohol abuse and dependence and a low rate of substance abuse disorders, the prevalence rates are similar to those obtained in North American studies using the NIMH-DIS as a survey instrument. The DSM-III criteria for alcohol abuse or dependence may be less applicable to Iceland than to North America, because of differences in what is culturally regarded as acceptable use of alcohol.     

Diagnosis-related groups for mental disorders, alcoholism, and drug abuse: evaluation and alternatives

Under the new federal prospective payment system, 15 of the 467 diagnosis-related groups (DRGs) cover mental disorders, including alcohol and substance abuse. The authors compare these 15 DRGs with some criteria of an ideal patient classification system. According to their assessment, the DRGs for mental disorders pose no administrative problems, but are not sufficiently homogeneous within categories or heterogeneous between categories. The authors conclude by discussing their own attempt to develop alternative DRGs, based on such variables as age, marital status, and type of treatment as well as on diagnosis.     

Inhalant use, abuse, and dependence among adolescent patients: commonly comorbid problems

OBJECTIVE: Little is known about adolescents with DSM-IV-defined inhalant abuse and dependence. The aim of this study was to compare comorbidity among (1) adolescents with inhalant use disorders, (2) adolescents who reported using inhalants without inhalant use disorder, and (3) other adolescent patients drawn from an adolescent drug and alcohol treatment program. METHOD: The authors examined 847 admissions of patients who had completed structured diagnostic assessments. The three groups were compared for noninhalant substance use disorders, posttraumatic stress disorder, conduct disorder, major depression, previous suicide attempts, and physical/sexual abuse and neglect. RESULTS: Adolescents with inhalant abuse or dependence (group 1; n = 28) were significantly more likely to meet lifetime criteria for abuse or dependence on alcohol, hallucinogens, nicotine, cocaine, and amphetamines, to have had major depression, and to have attempted suicide compared with other adolescent patients who reported never using inhalants (group 3); adolescents with inhalant use disorders also reported significantly more abuse and neglect. Adolescents with inhalant abuse or dependence (group 1) did not differ significantly on any measure compared with adolescents who reported using inhalants without an inhalant use disorder (group 2). CONCLUSIONS: Adolescent patients with a history of inhalant use, abuse, or dependence entering treatment should be carefully screened for noninhalant substance use disorders, major depression, suicidality, and abuse and neglect.     

Is cigarette smoking a gateway to alcohol and illicit drug use disorders? A study of youths with and without attention deficit hyperactivity disorder.

BACKGROUND: The goal of this study was to assess whether cigarette smoking is a gateway drug for subsequent alcohol and illicit drug abuse and dependence in youth with Attention Deficit Hyperactivity Disorder (ADHD), and to test if this association is stronger in ADHD youth relative to controls. METHODS: We used data from a case-control family study of female youth with and without ADHD. We studied 97 ADHD and 203 control youth of both sexes, aged at least 12 years. We assessed ADHD, smoking, and substance use status using structured diagnostic interviews. We tested the association between cigarette smoking and subsequent substance use outcomes using Cox proportional hazard regression models. RESULTS: ADHD youth who smoked cigarettes (n = 15) were significantly more likely to subsequently use alcohol and illicit drugs as well as to develop abuse and dependence compared to ADHD youth who did not smoke (n = 76; p < .05). CONCLUSIONS: These results extend the gateway hypothesis to an ADHD sample and provide evidence that this effect may be particularly robust in ADHD youth. If replicated in larger, community-based samples, these findings have important public health consequences, and underscore the already pressing need to prevent smoking in ADHD children.     

An epidemiological survey of alcohol use disorders in a Tibetan population

We performed an epidemiological survey in order to detect the prevalence of alcohol use disorders in a sub-group of the population of Tibet. The Alcohol Use Disorders Identification Test (AUDIT) questionnaire, the Severity of Alcohol Dependence Questionnaire (SADQ), and a 12-item version of the General Health Questionnaire (GHQ12) were used to obtain epidemiological data on alcohol use disorders and to assess the severity of ‘problem drinking’ and general mental health status. The AUDIT is a reliable and valid screening tool for both alcohol abuse and dependence in the Tibetan population to identify individuals with alcohol use problems. The cut-off points were set to be 10 and 13 of the AUDIT scores as a diagnostic discriminator of alcohol abuse and alcohol dependence, respectively, with both sensitivity and specificity > 0.84. The prevalence of alcohol abuse, was 2.7% (female: 2.0%; male: 6.2%), alcohol dependence 13.5% (female: 7.6%; male: 25.4%) and alcohol use disorders 16.2% (female: 9.6%; male: 31.6%). Age and sex were the main factors affecting an individual's alcohol use and general mental health status. The epidemiological data on alcohol use disorders documented in this project may be helpful in future work seeking more valid causal inferences or interpretations related to this prevalent health problem in Tibet.     

Prospective evaluation of the four DSM-IV criteria for alcohol abuse in a large population

OBJECTIVE: In 1994 DSM-IV presented new criteria for substance abuse as repetitive problems in any one of four areas reflecting social, interpersonal, and legal difficulties. The authors systematically evaluate the performance of each of the four diagnostic criteria for alcohol abuse (problems in role functioning, alcohol use in hazardous situations, alcohol-related legal problems, and social or interpersonal problems) and determine the prognosis associated with a threshold of one versus two or more criterion endorsements. METHOD: Baseline and 5-year follow-up data were analyzed for 2,596 men and women from the Collaborative Study on the Genetics of Alcoholism, including 1,881 individuals with no alcohol-related diagnosis, and 715 with alcohol abuse, after excluding subjects with alcohol dependence. Performance of each criterion was analyzed for the entire group and for the 565 individuals who endorsed only one criterion at baseline. RESULTS: One alcohol abuse criterion was endorsed by 79% of subjects with alcohol abuse, 18.5% endorsed two, and 2.5% endorsed three. Compared with subjects who endorsed no criteria, individuals who reported any of the four diagnostic criteria at baseline had higher rates of alcohol and drug intake and related problems and higher rates of future difficulties. Diagnostic thresholds of one versus two abuse criteria at baseline performed equally well regarding most outcomes, although endorsement of two criteria predicted a higher risk for progression to dependence. The criterion most frequently endorsed--hazardous use--was associated with baseline substance use characteristics and problematic outcomes similar to those for the other criteria. CONCLUSIONS: The four DSM-IV alcohol abuse criteria performed well regarding both cross-sectional characteristics and the prediction of future problems, but no single diagnostic criterion was superior to any other. The similarity of outcomes for subjects with diagnostic thresholds of one versus two or more criteria may favor the continued use of a threshold of one criterion in the diagnosis of alcohol abuse.     

Cigarette Smoking and Psychiatric Disorder in a Community Sample

We examined the lifetime prevalence of psychiatric disorders in cigarette smokers and nonsmokers in a non-patient sample. First-degree relatives of psychiatric patients (n = 697) and normal controls (n = 360) were interviewed with the Diagnostic Interview Schedule and the Structured Interview for DSM-III Personality Disorders. Using these interviews we diagnosed the major mental (Axis I) disorders and personality (Axis II) disorders. A cigarette smoker was defined as someone who smoked daily for a month or more at some time in their lives. We found that smokers more frequently had a lifetime history of major depression, alcohol and drug abuse/dependence, agoraphobia, unstable/acting out and anxious/fearful personality disorders. In a logistic regression analysis, the only significant variables independently associated with smoking status were the alcohol and drug use disorders. Age was an important modifying variable—the smoking-illness relationship was robust in the youngest age cohort and negligible in the oldest cohort. We conclude that cigarette smokers have increased rates of mood, anxiety, substance use, and personality disorders. However, after controlling for the comorbidity among the disorders only alcohol and drug abuse/dependence were independently associated with smoking. Young smokers had particularly high rates of substance use disorders. This age effect may reflect the impact of a quarter century of health education.     

Sociodemographic predictors of transitions across stages of alcohol use, disorders, and remission in the National Comorbidity Survey Replication

Background

Although much is known about risk factors for the initiation of alcohol use, abuse, and dependence, few population-based studies have examined the predictors of transitions across these stages.

Aim

The aim of this study is to examine the sociodemographic predictors of transitions across 6 stages of alcohol use in the National Comorbidity Survey Replication, a nationally representative household survey of the US population.

Methods

A lifetime history of alcohol use, regular use (at least 12 drinks in a year), Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition alcohol abuse and dependence with abuse was collected in 5692 National Comorbidity Survey Replication respondents using the World Health Organization Composite International Diagnostic Interview, Version 3.0.

Results

Lifetime prevalence estimates were 91.7% for lifetime alcohol use, 72.9% for regular use, 13.2% for abuse, and 5.4% for dependence with abuse. Male sex, young age, non-Hispanic white race/ethnicity, low education, student status, and never being married predicted the onset of alcohol use, the transition from use to regular use, and from regular use to abuse. An early age of onset of alcohol use also predicted the latter transition. The transition from abuse to dependence was associated with an early age of onset of regular alcohol use, being previously married, and student status. Remission was predicted by young age and a later age of onset of alcohol abuse.

Conclusion

The reduced number and magnitude of factors associated with transitions to dependence and remission suggest qualitatively different risk factors at these stages relative to other stages of progression. Further knowledge is needed concerning the mechanisms underlying these differences to guide selective and indicated prevention programs.     

Sex-specific genetic influences on the comorbidity of alcoholism and major depression in a population-based sample of US twins

BACKGROUND: Alcoholism and depression frequently co-occur, but the origins of this comorbidity remain uncertain. Most previous family, twin, and adoption studies of these disorders have used cases ascertained through treatment settings, who may differ from cases in epidemiological samples. We studied the importance of genetic influences on risk for lifetime comorbidity of major depression and alcoholism by means of a population-based twin sample. METHODS: Lifetime major depression (MD), alcohol abuse, and alcohol dependence were assessed by structured interview for both members of 3755 twin pairs from the Mid-Atlantic Twin Registry. Pair resemblance was analyzed by means of structural equation models. RESULTS: Individuals with MD were at significantly increased risk for alcohol dependence and for a combined diagnosis of alcohol abuse and/or dependence. History of MD in a twin significantly increased the risk of cotwin alcohol dependence and alcohol abuse and/or dependence among identical male pairs and for alcohol abuse and/or dependence in identical female pairs, but not among male or female fraternal pairs. Results of structural modeling indicate that comorbidity occurs because the genetic and specific environmental sources of liability to MD overlap with those underlying alcohol dependence and alcohol abuse and/or dependence. This overlap was significant only within sex, not across sexes. CONCLUSIONS: In this population-based twin sample, the familial transmission of MD and alcohol dependence was largely disorder specific. Comorbidity appears to be due to sex-specific genetic and environmental risk factors. The factors underlying depression in women do not appear to arise from the same factors underlying alcoholism in men.     

The Activity of β-Hexosaminidase (uHex) and y-Glutamyi-transferase (uGGT) in Urine as Non-Invasive Markers of Chronic Alcohol Abuse: II. Opiate-Dependent Subjects Receiving Methadone Substitution

Summary: The usefulness of β-hexosaminidase (uHex) and γ glutamyltransferase (uGGT) activity in urine as markers of chronic alcohol abuse was examined in male methadone programme participants. The group consisted of 24 non-abusing and 21 alcohol-abusing men. It has been demonstrated that the uHex test is one of the best alcohol abuse markers for opiate-dependent individuals (Receiver Operating Characteristic (ROC) area under the curve (AUC) 0.82, sensitivity 0.70, specificity 0.82). The uGGT test can be used as a marker of alcohol abuse in opiate-dependent men, however, its parameters are worse than those of uHex (ROC AUC 0.73, sensitivity 0.71, specificity 0.77). Among serum markers, only the relative amount of carbohydrate-deficient transferrin (s%CDT) has parameters sufficient for diagnostic use (ROC AUC 0.74, sensitivity 0.60, specificity 0.86). Factors other than alcohol can render the commonly used sGGT and sHex tests useless (differences between means for abusing and abstinent patients were insignificant, AUC ROC were lower than 0.7-0.65 and 0.69, respectively).

Their good parameters, low costs, ease of use and non-invasive character are all features which make uHex and uGGT highly useful tools in the detection of chronic alcohol abuse in opiate-dependent patients participating in a methadone substitution programme.     

The comorbidity of anxiety disorders with personality,depressive, alcohol and drug disorders

Anxiety disorders seldom exist in isolation from personality traits and disorders, from depressive symptomatology, and from alcohol and drug use and abuse. This review examines the relationships between anxiety disorders and these often comorbid psychiatric disorders. While diagnostic systems such as DSM-III-R which describe multiple, discrete disorders highlight comorbidity and may have value for treatment outcome and other studies, they appear unlikely to generate useful aetiological explanations of the considerable overlap of psychiatric symptomatology seen in anxiety disorder patients.
