Substance Dependence and Other Psychiatric Disorders Among Drug Dependent Subjects: Race and Gender Correlates

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 2 2000
Wilson M. Compton III M.D.
Persons in drug treatment with drug dependence were interviewed with the NIMH Diagnostic Interview Schedule to ascertain DSM-III-R disorders. Lifetime prevalence rates were 64% for alcohol dependence, 44% for antisocial personality disorder (ASPD), 39% for phobic disorders, 24% for major depression, 12% for dysthymia, 10% for generalized anxiety disorder, 3% for panic disorder, 3% for mania, 3% for obsessive compulsive disorder, 2% for bulimia, 1% for schizophrenia, and 1% for anorexia. When stratified by race and age, significant main effects were seen, but there were no significant interactions except in "any non-substance disorder" and in the mean number of non-substance use disorders. Caucasians had a higher mean number of drug dependence disorders and higher overall rates of "any other" disorder than African-Americans, and Caucasians and males had higher mean numbers of non-substance use disorders than African-Americans and females, respectively. This was related to rates of alcohol, cannabis, and hallucinogen dependence, and ASPD rates that were higher among men than women and higher among Caucasian respondents than African-American for alcohol, cannabis, hallucinogen, opiate and sedative dependence, major depression, dysthymia, and generalized anxiety disorder. In contrast, women had higher rates than men of amphetamine dependence, phobic disorder, major depression, dysthymia, panic disorder, obsessive compulsive disorder, and mania. African-Americans had higher rates than Caucasians of amphetamine, cocaine, and phencyclidine dependence, but for no comorbid disorders were the rates higher among African-Americans than Caucasians. The differences according to gender in rates of disorders among substance dependent persons are consistent with the results of general population surveys, but the differences in rates according to race are in contrast to these same community surveys. Limitations in the utility of the concept of race as a valid category diminish the generalizability of the findings; however, one possible explanation is differential treatment seeking in African-American and Caucasian populations that would result in the differences seen.

Neuropharmacology of addiction,setting the scene

BRITISH JOURNAL OF PHARMACOLOGY, Issue 2 2008
A J Lawrence
Addiction is a complex disorder, affecting not only the individual addict, but also their family and the community at large. While therapeutic strategies are available for the treatment of some forms of substance abuse/dependence, these are not without problems and are not universally efficacious. Moreover, in some instances (for example, cocaine addiction), there are still no medications specifically registered as treatment options. In this themed issue of the British Journal of Pharmacology, we highlight a number of addictions from a pharmacological perspective, with an emphasis on both mechanism and potential therapeutic approaches that are either under development or reflect preclinical work. As such, the authors endeavour to describe the latest thinking on the neural theory of addiction and corresponding novel pharmacotherapeutic targets, and in this way to set the stage for future advances in research and drug development. In addition, we have also attempted to draw attention to the clinicians' perspective in terms of the interface between basic science and care provision.

The targets of violence committed by young offenders with alcohol dependence, marijuana dependence and schizophrenia-spectrum disorders: findings from a birth cohort

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2002
Louise Arseneault
Background: Estimates of who is most at risk from violence by people with mental illness rest mainly on identified patient samples. This study, without such selection bias, examined the targets of violence committed by young adults with as-yet untreated alcohol dependence, marijuana dependence, or schizophrenia-spectrum disorders, to determine the extent to which their victims were co-residents or non-household members. Methods: In a total birth cohort of 21-year-olds (n = 956), past-year prevalence of alcohol dependence, marijuana dependence and schizophrenia-spectrum disorders were diagnosed using standardized DSM-III-R interviews. None of the people with schizophrenia-spectrum disorder has been hospitalized in the past year. Past-year violence and victim targets were measured using self-reports. Results: Compared with controls, cohort members with substance dependence or schizophrenia-spectrum disorders had higher prevalence and frequency rates of assault against co-residents, against non-household members, and also robbery and gang fights. Out of 39, five individuals with schizophrenia-spectrum disorder committed violent street crimes. Persons with substance dependence had similar proportions of violence against co-resident and non-household members, but persons with schizophrenia-spectrum disorders tended to victimize co-residents more than others. Conclusions: At the age when they are most likely to contribute to the community's violence burden, young untreated offenders with alcohol or marijuana dependence or with schizophrenia-spectrum disorders assault not only co-residents, but others as well, and commit violent street crimes. Families, schoolteachers and primary care physicians have an important potentially preventive role in early identification and treatment of the disorders. Copyright © 2002 Whurr Publishers Ltd.

Panic and suicidal ideation and suicide attempts: results from the National Comorbidity Survey

DEPRESSION AND ANXIETY, Issue 3 2006
M.P.H., Renee D. Goodwin Ph.D.
Abstract Our objective was to determine the association between panic attacks (PAs) and panic disorder (PD), and suicidal ideation (SI) and suicide attempts (SAs) in a nationally representative sample of adults in the community. Data were drawn from the National Comorbidity Survey (n=5,877), a representative household sample of adults ages 15,54 in the United States. Multiple logistic regression analyses were used to examine the relationship between current and lifetime PA and PD and SI and SA, adjusting for differences in demographic characteristics, comorbid mental disorders (major depression, alcohol dependence, and substance dependence), childhood trauma (physical and sexual abuse), and number of lifetime mental disorders. Past-year and lifetime PA and PD were associated with increased SI (both past year and lifetime), and persisted after adjusting for comorbidity and early trauma. Associations between PA and SA were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with lifetime SA, but these associations were no longer statistically significant after adjusting for comorbidity. Past-year and lifetime PD were associated with past-year SA, and this association persisted after adjusting for demographics, comorbidity, and number of lifetime mental disorders. These findings are consistent with previous results, and further help to clarify the relationships between panic and suicide behavior by identifying potential methodological reasons for inconsistencies in results from previous studies.

Process evaluation of an out-patient detoxification service

DRUG AND ALCOHOL REVIEW, Issue 6 2005
Dr CLAUDIA SANNIBALE
Abstract This paper describes the process evaluation of an out-patient detoxification service (ODS) established by Drug Health Services (DHS) to increase the supervised withdrawal options for substance users in a Sydney metropolitan Area Health Service. The ODS aimed to provide a safe and effective supervised withdrawal to substance users who were at low risk of severe withdrawal, engage those with severe dependence in further treatment and increase the involvement of general practitioners (GPs) in the medical care of ODS clients. During its first 10 months of operation, the ODS received 199 inquiries, assessed 82 individuals and admitted 76 clients for detoxification. Withdrawal treatment proceeded without complications and within the expected time frames. Fifty-four clients completed withdrawal, 10 ceased treatment, 10 remained in treatment without completing withdrawal and two were transferred elsewhere. Clients who injected substances (mainly heroin) daily at admission, compared to others, were less likely to complete withdrawal and more likely to use a range of non-prescribed substances during withdrawal. One-fifth of clients went on to further treatment with DHS, attending at least once. Overall, the ODS met its goals, providing a safe and effective supervised withdrawal to local residents, especially women, young people and those withdrawing from benzodiazepines who had significant substance dependence, impairment and previous alcohol and other drug (AOD) treatment. Non-injecting substance users benefited most from the ODS in terms of withdrawal completion and ongoing treatment. The level of GP involvement in the conjoint care of ODS clients remained constant over time. The development and expansion of the ODS are discussed. [source]


Mental disorders as risk factors for substance use, abuse and dependence: results from the 10-year follow-up of the National Comorbidity Survey

ADDICTION, Issue 6 2010
Joel Swendsen
ABSTRACT Aims The comorbidity of mental disorders and substance dependence is well documented, but prospective investigations in community samples are rare. This investigation examines the role of primary mental disorders as risk factors for the later onset of nicotine, alcohol and illicit drug use, abuse and dependence with abuse. Design The National Comorbidity Survey (NCS) was a nationally representative survey of mental and substance disorders in the United States carried out in 1990,92. The NCS-2 re-interviewed a probability subsample of NCS respondents in 2001,03, a decade after the baseline survey. Participants A total of 5001 NCS respondents were re-interviewed in the NCS-2 (87.6% of baseline sample). Results Aggregate analyses demonstrated significant prospective risks posed by baseline mental disorders for the onset of nicotine, alcohol and illicit drug dependence with abuse over the follow-up period. Particularly strong and consistent associations were observed for behavioral disorders and previous substance use conditions, as well as for certain mood and anxiety disorders. Conditional analyses demonstrated that many observed associations were limited to specific categories of use, abuse or dependence, including several mental disorders that were non-significant predictors in the aggregate analyses. Conclusions Many mental disorders are associated with an increased risk of later substance use conditions, but important differences in these associations are observed across the categories of use, abuse and dependence with abuse. These prospective findings have implications for the precision of prevention and treatment strategies targeting substance use disorders. [source]


Anabolic,androgenic steroid dependence: an emerging disorder

ADDICTION, Issue 12 2009
Gen Kanayama
ABSTRACT Aims Anabolic,androgenic steroids (AAS) are widely used illicitly to gain muscle and lose body fat. Here we review the accumulating human and animal evidence showing that AAS may cause a distinct dependence syndrome, often associated with adverse psychiatric and medical effects. Method We present an illustrative case of AAS dependence, followed by a summary of the human and animal literature on this topic, based on publications known to us or obtained by searching the PubMed database. Results About 30% of AAS users appear to develop a dependence syndrome, characterized by chronic AAS use despite adverse effects on physical, psychosocial or occupational functioning. AAS dependence shares many features with classical drug dependence. For example, hamsters will self-administer AAS, even to the point of death, and both humans and animals exhibit a well-documented AAS withdrawal syndrome, mediated by neuroendocrine and cortical neurotransmitter systems. AAS dependence may particularly involve opioidergic mechanisms. However, AAS differ from classical drugs in that they produce little immediate reward of acute intoxication, but instead a delayed effect of muscle gains. Thus standard diagnostic criteria for substance dependence, usually crafted for acutely intoxicating drugs, must be adapted slightly for cumulatively acting drugs such as AAS. Conclusions AAS dependence is a valid diagnostic entity, and probably a growing public health problem. AAS dependence may share brain mechanisms with other forms of substance dependence, especially opioid dependence. Future studies are needed to characterize AAS dependence more clearly, identify risk factors for this syndrome and develop treatment strategies. [source]


Subtypes of major depression in substance dependence

ADDICTION, Issue 10 2009
Mark J. Niciu
ABSTRACT Aims This study evaluated features that differentiate subtypes of major depressive episode (MDE) in the context of substance dependence (SD). Design Secondary data analysis using pooled data from family-based and case,control genetic studies of SD. Setting Community recruitment through academic medical centers. Participants A total of 1929 unrelated subjects with alcohol and/or drug dependence. Measurements Demographics, diagnostic criteria for psychiatric and substance use disorders and related clinical features were obtained using the Semi-Structured Assessment for Drug Dependence and Alcoholism. We compared four groups: no life-time MDE (no MDE), independent MDE only (I-MDE), substance-induced MDE only (SI-MDE) and both types of MDE. Findings Psychiatric measures were better predictors of MDE subtype than substance-related or socio-demographic ones. Subjects with both types of MDE reported more life-time depressive symptoms and comorbid anxiety disorders and were more likely to have attempted suicide than subjects with I-MDE or SI-MDE. Subjects with both types of MDE, like those with I-MDE, were also more likely than subjects with SI-MDE to be alcohol-dependent only than either drug-dependent only or both alcohol- and drug-dependent. Conclusions SD individuals with both types of MDE have greater psychiatric severity than those with I-MDE only or SI-MDE only. These and other features that distinguish among the MDE subtypes have important diagnostic and potential therapeutic implications. [source]


Sexual orientation, substance use behaviors and substance dependence in the United States

ADDICTION, Issue 8 2009
Sean Esteban McCabe
ABSTRACT Aims To assess past-year prevalence rates of substance use behaviors and substance dependence across three major dimensions of sexual orientation (identity, attraction and behavior) in a large national sample of adult women and men in the United States. Design Data were collected from structured diagnostic face-to-face interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule DSM-IV version IV (AUDADIS-IV). Setting Prevalence estimates were based on data collected from the 2004,2005 (wave 2) National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Participants A large national sample of 34 653 adults aged 20 years and older: 52% female, 71% white, 12% Hispanic, 11% African American, 4% Asian and 2% Native American. Findings Approximately 2% of the population self-identified as lesbian, gay or bisexual; 4% reported at least one life-time same-sex sexual partner and 6% reported same-sex sexual attraction. Although non-heterosexual orientation was generally associated with a higher risk of substance use and substance dependence, the majority of sexual minority respondents did not report substance use or meet criteria for DSM-IV substance dependence. There was considerable variation in substance use outcomes across sexual orientation dimensions; these variations were more pronounced among women than among men. Conclusions Results support previous research findings of heightened risk of substance use and substance dependence among some sexual minority groups and point to the need for research that examines the reasons for such differences. Results also highlight important gender differences and question previous findings indicating uniformly higher risk for substance dependence among sexual minorities. Risks appear to vary based on gender and how sexual orientation is defined. Findings have implications for more effective prevention and intervention efforts that target subgroups at greatest risk.

Results from two randomized clinical trials evaluating the impact of quarterly recovery management checkups with adult chronic substance users

ADDICTION, Issue 6 2009
Christy K Scott
ABSTRACT Aims Post-discharge monitoring and early reintervention have become standard practice when managing numerous chronic conditions. These two experiments tested the effectiveness of recovery management checkup (RMC) protocols for adult chronic substance users. Intervention RMC included quarterly monitoring; motivational interviewing to provide personalized feedback and to resolve ambivalence about substance use; treatment linkage, engagement and retention protocols to increase the amount of treatment received. Participants and setting Recruited from sequential addiction treatment admissions, participants in the two experiments were, on average, 36 and 38 years of age, mainly female (59% versus 46%), African American (85% versus 80%) and met past-year criteria for dependence (87% versus 76%). Design Participants in both experiments were assigned randomly to the RMC or control condition and interviewed quarterly for 2 years. Measurement The Global Appraisal of Individual Needs (GAIN) was the main assessment instrument. Findings RMC participant outcomes were better than control participants in both experiments. Effect sizes were larger in the second experiment in terms of reducing days to readmission (Cohen's d = 0.41 versus d = 0.22), successive quarters in the community using substances (d = ,0.32 versus ,0.19), past-month symptoms of abuse/dependence (d = ,0.23 versus ,0.02) and increasing the days of abstinence over 2 years (d = +0.29 versus 0.04). Conclusion RMC, which provided ongoing monitoring and linkage, is feasible to conduct and is effective for adults with chronic substance dependence. [source]


A double-blind, placebo-controlled trial of modafinil (200 mg/day) for methamphetamine dependence

ADDICTION, Issue 2 2009
James Shearer
ABSTRACT Aim To examine the safety and efficacy of modafinil (200 mg/day) compared to placebo in the treatment of methamphetamine dependence and to examine predictors of post-treatment outcome. Participants and design Eighty methamphetamine-dependent subjects in Sydney, Australia were allocated randomly to modafinil (200 mg/day) (n = 38) or placebo (n = 42) under double-blind conditions for 10 weeks with a further 12 weeks post- treatment follow-up. Measures Comprehensive drug use data (urine specimens and self-report) and other health and psychosocial data were collected weekly during treatment and research interviews at baseline, week 10 and week 22. Results Treatment retention and medication adherence were equivalent between groups. There were no differences in methamphetamine abstinence, craving or severity of dependence. Medication-compliant subjects tended to provide more methamphetamine-negative urine samples over the 10-week treatment period (P = 0.07). Outcomes were better for methamphetamine-dependent subjects with no other substance dependence and those who accessed counselling. There were statistically significant reductions in systolic blood pressure (P = 0.03) and weight gain (P = 0.05) in modafinil-compliant subjects compared to placebo. There were no medication-related serious adverse events. Adverse events were generally mild and consistent with known pharmacological effects. Conclusions Modafinil demonstrated promise in reducing methamphetamine use in selected methamphetamine-dependent patients. The study findings support definitive trials of modafinil in larger multi-site trials. [source]


Incentive-elicited striatal activation in adolescent children of alcoholics

ADDICTION, Issue 8 2008
James M. Bjork
ABSTRACT Aims Deficient recruitment of motivational circuitry by non-drug rewards has been postulated as a pre-morbid risk factor for substance dependence (SD). We tested whether parental alcoholism, which confers risk of SD, is correlated with altered recruitment of ventral striatum (VS) by non-drug rewards in adolescence. Design During functional magnetic resonance imaging, adolescent children of alcoholics (COA; age 12,16 years) with no psychiatric disorders (including substance abuse) and similarly aged children with no risk factors responded to targets to win or avoid losing $0, $0.20, $1, $5 or a variable amount (ranging from $0.20 to $5). Results In general, brain activation by either reward anticipation or outcome notification did not differ between COA and age/gender-matched controls. Cue-elicited reward anticipation activated portions of VS in both COA and controls. In nucleus accumbens (NAcc), signal change increased with anticipated reward magnitude (with intermediate recruitment by variable incentives) but not with loss magnitudes. Reward deliveries activated the NAcc and mesofrontal cortex in both COA and controls. Losses activated anterior insula bilaterally in both groups, with more extensive right anterior insula activation by losses in controls. NAcc signal change during anticipation of maximum rewards (relative to non-reward) correlated positively with both Brief Sensation-Seeking Scale scores and with self-reported excitement in response to maximum reward cues (relative to cues for non-reward). Conclusions Among adolescents with no psychiatric disorders, incentive-elicited VS activation may relate more to individual differences in sensation-seeking personality than to presence of parental alcoholism alone. Future research could focus on adolescents with behavior disorders or additional risk factors. [source]


Subtypes of substance dependence and abuse: implications for diagnostic classification and empirical research

ADDICTION, Issue 2006
Thomas F. Babor
ABSTRACT Aims To evaluate the relevance of a form of diagnostic classification called clinical subtyping in relation to possible revisions in the diagnostic criteria for substance abuse and dependence in psychiatric classification systems. Methods A general rationale for subtyping is presented. To explore the implications for diagnostic classification, recent research on a variety of subtyping schemes is reviewed in terms of the development of new subtypes and the validation of established theories. Results Subtypes of alcoholism and other psychiatric disorders have been proposed since the beginning of modern psychiatry. Recent subtyping research suggests that no consensus has emerged about the nature, much less the number, of subtypes that could be used to characterize the clinical heterogeneity assumed to be present in groups of people with substance use disorders. Although several relatively simple binary typologies have been developed (e.g. Cloninger's type I and type II; Babor et al.'s type A and type B), validation research has produced mixed results in terms of the construct, concurrent and predictive validity of these classifications. Conclusions The adoption of a subtyping scheme in the major psychiatric classification systems is not recommended until further international research is conducted. [source]


Drinking patterns in mid-adolescence and psychosocial outcomes in late adolescence and early adulthood

ADDICTION, Issue 12 2004
J. Elisabeth Wells
ABSTRACT Aims To describe the pattern of drinking at age 16 and to relate this to outcomes at 16,21 years and 21,25 years across a number of psychosocial domains. Design A prospective birth cohort study with annual follow-up until age 16 then at 18, 21 and 25 years. Setting Christchurch, New Zealand. Participants Of 1265 subjects, 953 were interviewed at age 16. Measurements Multiple measures of family background were collected from birth to 16 years. Alcohol consumption was measured in terms of frequency, usual or last quantity drunk and most drunk per occasion. Problems were also recorded. Questions about psychiatric symptoms enabled Diagnostic and Statistical Manual (DSM) criteria to be applied. Detailed reports on educational outcomes, employment, sexual behaviours and offending were collected. Findings Four latent classes were required to describe drinking at age 16, but these appeared to lie along a single dimension which strongly predicted outcomes at ages 16,21 and 21,25 across all domains (alcohol-related, substance dependence, mental health, education, sexual relationships and offending). After controlling for background and correlates only a small number of outcomes were still related consistently to drinking at age 16 over both periods: most alcohol-related outcomes, the number of sexual partners and the extent of violent offending. Conclusions Drinking at age 16 is a clear indicator of future life-course over most domains in late adolescence and early adulthood. Many of these associations are due to other covariates. Outcomes specific to drinking at age 16 are alcohol outcomes, number of sexual partners and violence. [source]


HUMAN STUDY: FOSB proteins in the orbitofrontal and dorsolateral prefrontal cortices of human alcoholics

ADDICTION BIOLOGY, Issue 3 2009
Hiroyuki Watanabe
ABSTRACT The transcription factor ,FosB is accumulated in the addiction circuitry, including the orbitofrontal and medial prefrontal cortices of rodents chronically exposed to ethanol or other drugs of abuse, and has been suggested to play a direct role in addiction maintenance. To address this hypothesis in the context of substance dependence in humans, we compared the immunoreactivities of FOSB proteins in the orbitofrontal and dorsolateral prefrontal cortices (OFC and DLPFC respectively) between controls and alcoholics using semiquantitative immunoblotting. In both structures, we detected three forms of FOSB, one of which was ,FOSB, but in neither case did their immunoreactivities differ between the groups. Our results indicate that the ,FOSB immunoreactivity in the human brain is very low, and that it is not accumulated in the OFC and DLPFC of human alcoholics, suggesting that it may not be directly involved in addiction maintenance, at least not in ethanol dependence.

Relational Factors and Family Treatment Engagement among Low-Income, HIV-Positive African American Mothers

FAMILY PROCESS, Issue 1 2003
Victoria B. Mitrani Ph.D.
Clinically derived hypotheses regarding treatment engagement of families of low-income, HIV-positive, African American mothers are tested using univariate and multivariate logistic regression models. Predictors are baseline family relational factors (family support, mother's desire for involvement with family, and family hassles) and mother's history of substance dependence. The study examines a subsample of 49 mothers enrolled in a clinical trial testing the efficacy of Structural Ecosystems Therapy (SET). SET is a family-based intervention intended to relieve and prevent psychosocial distress associated with HIV/AIDS. Participants in the subsample were randomly assigned to SET and attended at least two therapy sessions. Findings reveal that family relational factors predicted family treatment engagement (family support, p < 004; mother's desire for involvement with family, p < 008; family hassles, p < 027). Family support predicted family treatment engagement beyond the prediction provided by the other relational factors and the mother's own treatment engagement (p < 016). History of substance dependence was neither associated with family treatment engagement nor family support. Post hoc analyses revealed that family hassles (p < 003) and mother's desire for involvement with family (p < 018) were differentially related to family treatment engagement in low-versus high-support families. Implications for clinical practice and future research are discussed. [source]


Prefrontal cortex activity is reduced in gambling and nongambling substance users during decision-making,

HUMAN BRAIN MAPPING, Issue 12 2007
Jody Tanabe
Abstract Objective: Poor decision-making is a hallmark of addiction, whether to substances or activities. Performance on a widely used test of decision-making, the Iowa Gambling Task (IGT), can discriminate controls from persons with ventral medial frontal lesions, substance-dependence, and pathological gambling. Positron emission tomography (PET) studies indicate that substance-dependent individuals show altered prefrontal activity on the task. Here we adapted the IGT to an fMRI setting to test the hypothesis that defects in ventral medial and prefrontal processing are associated with impaired decisions that involve risk but may differ depending on whether substance dependence is comorbid with gambling problems. Method: 18 controls, 14 substance-dependent individuals (SD), and 16 SD with gambling problems (SDPG) underwent fMRI while performing a modified version of the IGT. Result: Group differences were observed in ventral medial frontal, right frontopolar, and superior frontal cortex during decision-making. Controls showed the greatest activity, followed by SDPG, followed by SD. Conclusion: Our results support a hypothesis that defects in ventral medial frontal processing lead to impaired decisions that involve risk. Reductions in right prefrontal activity during decision-making appear to be modulated by the presence of gambling problems and may reflect impaired working memory, stimulus reward valuation, or cue reactivity in substance-dependent individuals.

Are there subgroups of bulimia nervosa based on comorbid psychiatric disorders?

INTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 1 2005
Alexis E. Duncan MPH
Abstract Objective The current study sought to determine whether there are subtypes of bulimia nervosa (BN) differentiated by comorbid psychiatric disorders. Method Data on comorbid psychiatric diagnoses in female relatives of probands and controls in the Collaborative Study of the Genetics of Alcoholism (COGA) who met criteria for BN (as outlined in the 3rd Rev. ed. of the Diagnostic and Statistical Manual of Mental Disorders) were analyzed using latent class analysis. Resulting latent classes were compared on a variety of variables related to impulsive behaviors and psychological functioning. Results The best-fitting solution, a two-class model, yielded one class (72%) characterized by substance dependence, depression, antisocial personality disorder (ASPD), and anxiety disorders, and another characterized by depression. The highly comorbid class had more suicidality, more daily smokers, sought help for emotional problems, and had lower Global Assessment of Functioning (GAF) scores compared with those in the comorbid depression only class. Discussion Latent class findings suggest the existence of two classes of BN differentiated by substance dependence, impulsive behaviors, and poorer psychological functioning. © 2004 by Wiley Periodicals, Inc.

A comparison of psychiatric consultation between geriatric and non-geriatric medical inpatients

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 10 2009
Sarah E. Schellhorn
Abstract Objective The authors examine changes in psychiatric referral patterns for geriatric inpatients since last reported in the United States, more than 20 years ago, and compare geriatric psychiatric referrals to those of a non-geriatric cohort. Method Retrospective study comparing psychiatric diagnosis, treatment and aftercare of younger (ages 18,60 years, n,=,474) and older (>60 years, n,=,487) patients seen in psychiatric consultation in a large, urban, university-based tertiary care hospital setting. Results Compared to previous reports in the literature, this cohort contains a notably higher percentage of the ,old-old' (>80 years), reflecting the general aging of those who are hospitalized. Compared to younger patients, geriatric inpatients were more commonly referred for psychiatric consultation, but overall rates of referral remain low (<4%). Geriatric patients were diagnosed with dementia and delirium more frequently; with substance dependence less frequently; and were just as likely to be diagnosed with depression. Geriatric patients were also more likely to receive atypical antipsychotic medications and less likely to receive benzodiazepines than younger patients. In patients diagnosed with depression, psychiatric follow-up is more likely relegated to outpatient geriatricians and nursing homes. Conclusions Consulting psychiatrists frequently encounter geriatric patients and, given patterns of diagnosis and aftercare, should play a major role in medical staff education and in development of enhanced in-hospital and aftercare services, including psychiatric liaison.

A dimensional option for the diagnosis of substance dependence in DSM-V

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue S1 2007
John E. Helzer
Abstract In this paper we discuss the creation of dimensional equivalents for categorically defined substance use disorders (SUDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), which now is being created. We begin with a review of the considerable literature that has accumulated on the dimensional properties of the SUDs. These studies have primarily examined the alcohol use disorders, but work relevant to other substances is reviewed as well. The weight of evidence indicates that SUDs fit well into a unidimensional concept. We next discuss potential advantages, drawbacks, and challenges in developing a dimensional alternative for the SUDs and highlight some issues for an ongoing research agenda to further explore the challenges. Finally we offer a specific proposal for a SUDs dimensional option for DSM-V. The model we propose is based on, and would relate directly back to, the categorical criteria that will be created for the SUDs by the substance use diagnostic workgroup. It is our contention that offering a dimensional equivalent for the DSM-V categories would be of great value, but that the categorical and dimensional definitions should be based on the same symptoms and closely linked. A dimensional scale that does not related directly to the categorical definition would be counterproductive. Copyright © 2007 John Wiley & Sons, Ltd. [source]


Cognitive,behavior therapy for PTSD in rape survivors

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 8 2002
Lisa H. Jaycox
In recent years, new data have appeared, further suggesting the utility of cognitive,behavioral interventions for posttraumatic stress disorder (PTSD) subsequent to sexual assault. In this article, we present a model of cognitive,behavioral treatment (CBT) for PTSD in rape survivors. Emotional-processing theory, which proposes mechanisms that underlie the development of disturbances following rape, is reviewed. A CBT-based therapy (Prolonged Exposure) is presented that entails education about common reactions to trauma, relaxation training, imaginal reliving of the rape memory, exposure to trauma reminders, and cognitive restructuring. Current research regarding the use of prolonged exposure is discussed. The case example of a young female rape survivor is described in detail, and her prior substance dependence and intense shame are highlighted. The therapy was successful in reducing the client's symptoms of PTSD, as well as her depressive symptoms, and these gains were maintained at a one-year follow-up assessment. © 2002 Wiley Periodicals, Inc.

Effects of the History of Conduct Disorder on the Iowa Gambling Tasks

ALCOHOLISM, Issue 3 2006
Yang Tae Kim
Background: Recent research conducted with the Iowa Gambling Task (GT) suggests decision-making impairments in substance dependence, as well as behavior disorders such as conduct disorder and attention-deficit/hyperactivity disorder. However, little is known about the past history of conduct disorder on decision making. The purpose of this study was to test the possible effect of past history of conduct disorder on GT performance and how this factor could contribute to the performance on GT in alcohol-dependent patients. Methods: Four subject groups were tested: (1) alcohol-dependent patients with (n=28) and (2) alcohol-dependent patients without (n=28), a history of conduct disorder and (3) normal controls with (n=10) and (4) normal controls without (n=30) a history of conduct disorder. Demographic and alcohol-related variables were evaluated, and a decision-making task, "Iowa GT," both original and variant version, were applied. Results: As a whole, normal controls with a history of conduct disorder and alcohol-dependent patients with or without a history of conduct disorder show impaired decision making because of hypersensitivity to reward and hyposensitivity to punishment. However, no significant differences were noted between alcohol-dependent patients either with or without a history of conduct disorder on gambling performance. Conclusions: These results indicate that the history of conduct disorder may contribute to impaired decision making on GT. Furthermore, this kind of decision-making pattern may represent one of common underlying mechanisms in both conduct disorder and alcohol dependence. [source]


Hypericum perforatum and substance dependence: a review

PHYTOTHERAPY RESEARCH, Issue 5 2008
Tayfun I. Uzbay
Abstract Substance abuse and dependence is a serious problem throughout the world. The development of several types of dependence remedies has medical, social and economical significance. In particular, alcohol and tobacco are the most commonly abused substances worldwide. An extract of Hypericum perforatum L. (HPE) displayed a clear antidepressant action and it has been used for the treatment of mild to moderate depression. Recent reports imply that HPE may be effective in the treatment of substance abuse. Studies have focused on alcohol and nicotine dependence. In this review, the effects of HPE on substance dependence and its possible benefit have been discussed in the light of current literature. Copyright © 2008 John Wiley & Sons, Ltd. [source]


Drug Interactions between Antiretroviral Medications and Medications Used in the Treatment of Drug Addiction: Research Needs

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 1 2010
Jag H. Khalsa PhD
Today substance dependence is one of the major public health problems in the world with millions of people abusing legal and illegal drugs. In addition, almost one-third of the world's population suffers with one or more infections. Both drugs of abuse and infections are associated with serious medical and health consequences, some of which may be exacerbated by the occurrence of pharmacokinetic and/or pharmacodynamic interactions between medications used in the treatment of these conditions when they co-occur. This review briefly discusses issues surrounding clinical management related to drug interactions experienced by substance abusing patients. The emphasis of this paper is on the research needed to further study the extent, nature, and underlying molecular/genetic mechanism(s) of interactions between drugs of abuse, medications used in the treatment of drug addiction, and co-occurring infections.,(Am J Addict 2009;19:96,100) [source]


Brief Integrated Outpatient Dual-diagnosis Treatment Reduces Psychiatric Hospitalizations

THE AMERICAN JOURNAL ON ADDICTIONS, Issue 4 2003
Eric Granholm Ph.D.
A retrospective pilot study was conducted to determine whether a relatively brief integrated outpatient treatment for patients with dual disorders reduced inpatient hospital service utilization. Outpatients (n = 44) with substance dependence and either comorbid schizophrenia, major depressive disorder, or bipolar disorder were studied. A multidisciplinary team provided relatively brief (up to 24 weeks), integrated, dual-diagnosis outpatient treatment. A significant 60% reduction in the number of psychiatric hospitalization days was found for the year after treatment as compared to the year before. Patients with schizophrenia showed the greatest reduction (74%) in hospitalization days. Thus, even brief integrated outpatient dual-diagnosis treatment can reduce inpatient psychiatric hospitalizations. [source]


Approach to treatment of mental illness and substance dependence in remote Indigenous communities: Results of a mixed methods study

AUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 4 2009
Tricia Nagel
Abstract Objective:,To develop and evaluate a culturally adapted brief intervention for Indigenous people with chronic mental illness. Design:,A mixed methods design in which an exploratory phase of qualitative research was followed by a nested randomised controlled trial. Setting:,Psycho-education resources and a brief intervention, motivational care planning (MCP), were developed and tested in collaboration with aboriginal mental health workers in three remote communities in northern Australia. Participants:,A total of 49 patients with mental illness and 37 carers were recruited to a randomised controlled trial that compared MCP (n = 24) with a clinical control condition (treatment as usual, n = 25). Intervention:,The early treatment group received MCP at baseline and the late treatment group received delayed treatment at six months. Main outcome measures:,The primary outcome was mental health problem severity as measured by the health of the nation outcome scales. Secondary measures of well-being (Kessler 10), life skills, self-management and substance dependence were chosen. Outcome assessments were performed at baseline, six-month, 12-month and 18-month follow up. Results:,Random effects regression analyses showed significant advantage for the treatment condition in terms of well-being with changes in health of the nation outcome scales (P < 0.001) and Kessler 10 (P = 0.001), which were sustained over time. There was also significant advantage for treatment for alcohol dependence (P = 0.05), with response also evident in cannabis dependence (P = 0.064) and with changes in substance dependence sustained over time. Conclusions:,These results suggest that MCP is an effective treatment for Indigenous people with mental illness and provide insight into the experience of mental illness in remote communities.

Can We Help Addicts Become more Autonomous?

BIOETHICS, Issue 5-6 2003
Inside the Mind of An Addict
ABSTRACT I examine the impact of addiction on autonomy in terms of the standard literature on addiction , referred to also as ,substance dependence.'1 Then in terms of the criteria for substance dependence, by developing a set of practical strategies to help people with addictions think more clearly, I test the idea whether addicts can be helped to become more autonomous. Given that unsuccessful attempts to quit constitute part of the criteria of substance dependence, I look at what goes wrong when people try to quit using a substance. The subjective experience of addiction is an important aid in understanding addiction and first person accounts and literary characterisations of addiction provide insight into the addict's mind and assist us in deciding whether addicts can be helped to become more autonomous.

Strategies of emotion regulation in adolescents and young adults with substance dependence or eating disorders

CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 6 2002
Blaise Pierrehumbert
Some authors argue that both substance dependence and eating disorders should be considered as dependent behaviours. Similarities and differences between these disorders, however, remain unclear. This study compares processes of emotion regulation in adolescents and young adults (15 to 25 years old) with substance dependence (SD) or eating disorders (ED). One hundred and thirteen SD, 50 ED and 86 non-clinical subjects (NC), recruited in four French and Swiss locations, completed a self-report questionnaire of emotion regulation strategies. This questionnaire addresses the subjects' relationships, concerning past and present family, and refers to Main's (1990) concept of primary strategy (balanced activation and deactivation of attachment behaviours), and of secondary strategies (hyperactivation or excessive deactivation of the attachment system). Participants were also questioned in structured interviews, about life events and DSM-IV classification criteria. SD reported more adverse events than ED and NC. SD and ED reported using fewer primary strategies than NC, and SD had secondary strategies that were different from those of ED. Patients with eating disorders reported more hyperactivation, and SD reported more deactivation of the attachment system. It is hypothesized that while subjects with SD and ED have in common poorly regulated strategies, they differ in the way they process emotion or relationship-related information.
