Living With Dual Diagnosis and Homelessness: Marginalized Within a Marginalized Group

Objective: Concurrent mental and substance use disorders or dual diagnosis are highly prevalent among individuals experiencing homelessness. Studies have indicated that dual diagnosis leads to poorer health outcomes and higher health service utilization among those affected. This study aims to estimate the prevalence of dual diagnoses among homeless populations in British Columbia (BC), Canada, and understand their characteristics and specific factors associated with dual diagnoses. Methods: The BC Health of the Homeless Survey is a cross-sectional study involving the homeless population of three cities in BC. The survey assessed addiction and concurrent disorders with standardized interviews—the Mini-International Neuropsychiatric Interview Plus, the Maudsley Addiction Profile, and the Brief Symptom Inventory—in a sample of 500 individuals who are homeless living in shelters or on the street. We characterized individuals after categorizing them into four groups: those without any current mental disorder, those with substance use disorders only, those with mental disorders only, and those with concurrent substance use and mental disorders. Focusing on the concurrent disorder group, we completed a multivariate analysis comparing individuals with dual diagnosis to those without concurrent disorders. Results: Consistent with previous studies, we found that individuals with dual diagnoses report more severe physical and psychological symptoms. Among the homeless, they were more likely to be Aboriginal and younger and more likely to not make it into a shelter. They also reported substantially more difficulties in getting the health care service that they need. Conclusions: Within this marginalized group, individuals with dual diagnosis were more likely to be from groups considered to be more vulnerable with more complex needs. They were having more problems accessing even basic support, such as shelters and health care. Without a systematic approach in providing appropriate care to individuals with dual diagnosis, the most vulnerable clients are not only the ones likely to suffer the most but also the ones having the most problems meeting their basic needs.     

Concurrent Disorders and Health Care Utilization Among Homeless and Vulnerably Housed Persons in Canada

Objective: Individuals who are homeless or vulnerably housed have a higher prevalence of concurrent disorders, defined as having a mental health diagnosis and problematic substance use, compared to the general housed population. The study objective was to investigate the effect of having concurrent disorders on health care utilization among homeless or vulnerably housed individuals, using longitudinal data from the Health and Housing in Transition Study. Methods: In 2009, 1190 homeless or vulnerably housed adults were recruited in Ottawa, Toronto, and Vancouver, Canada. Participants completed baseline interviews and four annual follow-up interviews, providing data on sociodemographics, housing history, mental health diagnoses, problematic drug use with the Drug Abuse Screening Test (DAST-10), problematic alcohol use with the Alcohol Use Disorders Identification Test (AUDIT), chronic health conditions, and utilization of the following health care services: emergency department (ED), hospitalization, and primary care. Concurrent disorders were defined as the participant having ever received a mental health diagnosis at baseline and having problematic substance use (i.e., DAST-10 ≥ 6 and/or AUDIT ≥ 20) at any time during the study period. Three generalized mixed effects logistic regression models were used to examine the independent association of having concurrent disorders and reporting ED use, hospitalization, or primary care visits in the past 12 months. Results: Among our sample of adults who were homeless or vulnerably housed, 22.6% (n = 261) reported having concurrent disorders at baseline. Individuals with concurrent disorders had significantly higher odds of ED use (adjusted odds ratio [AOR] = 1.71; 95% confidence interval [CI], 1.4–2.11), hospitalization (AOR = 1.45; 95% CI, 1.16–1.81), and primary care visits (AOR = 1.34; 95% CI, 1.05–1.71) in the past 12 months over the four-year follow-up period, after adjusting for potential confounders. Conclusions: Concurrent disorders were associated with higher rates of health care utilization when compared to those without concurrent disorders among homeless and vulnerably housed individuals. Comprehensive programs that integrate mental health and addiction services with primary care as well as community-based outreach may better address the unmet health care needs of individuals living with concurrent disorders who are vulnerable to poor health outcomes.     

Domains and Perceived Benefits of Treatment Among Patients With and Without Co-Occurring Disorders in Inpatient Substance Use Treatment

Objective: Persons with substance use disorders often have comorbid psychiatric problems, and treating all problem domains is important for treatment success and recovery. This study examined reported interventions provided to patients as well as patients’ reports of domains of help received, perceived areas of greatest benefit, and satisfaction with substance use disorder treatment. We also compared patients with co-occurring disorders and patients with only substance use disorders to see whether there were significant differences across groups on these measures. Methods: Patients receiving inpatient substance use treatment at clinics in Norway were recruited for the study; 85 completed a cross-sectional survey prior to discharge. Treatment personnel also completed a separate survey and gathered information from patient charts. Results: The most frequently provided treatment interventions involved improving relationships with family and important others, applied relaxation, psychodynamic therapy, cognitive behavior therapy, and motivational interviewing. Patients reported receiving the most help in domains of relapse prevention, physical health, daily functioning, relationships with people, psychological health, and self-esteem. They benefited most from physical activities, support from co-patients, group therapy, counseling, and assessment/treatment of psychological health. Patients with co-occurring disorders were given more exposure therapy, motivational interviewing, and cognitive behavior therapy interventions than those without comorbidity. Patients with co-occurring disorders self-reported receiving more help with self-esteem and coping with psychiatric symptoms and benefiting more from interventions involving psychological health, acute help, and social situations. Conclusions: Patients perceived psychological and physical health as important areas for improvement. There were differences between patients with co-occurring disorders and those with substance use disorders only in several measures. It is important to acknowledge that patients with substance use disorders and co-occurring mental problems are heterogeneous groups with unique but overlapping needs.     

Cigarette Smoking in Youths With Mental Health and Substance Use Problems: Prevalence,Patterns, and Potential for Intervention

Mental health symptoms and substance use disorders are clear risk factors for cigarette smoking and nicotine dependence among young people, yet research on cigarette smoking among youths with concurrent mental health and substance use disorders (“dual diagnosis”) is considerably lacking. We examined smoking history and perspectives regarding smoking, cessation, and mental health and substance use in 97 adolescents and emerging adults (ages 14 to 24) referred to a program for youths with concurrent mental health and substance use disorders in Canada. Results show high rates of cigarette smoking, and modest interest in quitting but little interest in attending formalized programs to assist with cessation. Many participants reported smoking more when mental health was worse; most reported that they frequently smoke cigarettes and use drugs or alcohol concurrently. Current smokers perceived more benefits from cigarette smoking in regulating emotions and ameliorating their mental health symptoms than former smokers. In contrast, perceived detrimental effects of smoking were unrelated to current smoking status. Results suggest a need for integrated treatment that incorporates emotion regulation as part of cessation approaches. Integrating smoking cessation approaches into existing mental health and substance use treatments may be more palatable to adolescents and emerging adults than stand-alone smoking cessation programs.     

Evidence-based practices for co-occurring disorders in offenders

Individuals with substance use and concurrent mental disorders or co-occurring disorders (CODs) present numerous risks and treatment challenges. CODs are particularly pronounced within criminal justice settings. Offenders with CODs have higher risk for recidivism and have unique problems including criminal thinking and antisocial behaviours, commonly referred to as “criminogenic needs”. Two important frameworks for treating CODs with offender populations are the Risk-Need-Responsivity Model (RNR) and the Social Learning Model (SLM). These help to guide the application of integrated evidence-based treatments (EBTs) including Cognitive Behavioural Therapy (CBT), Motivational Interviewing (MI), behavioural modification, behavioural social skills training and family therapy. Programmatic adaptions include comprehensive screening/assessment, specialised tracks for dual diagnoses, intensive and phased treatment, ancillary services (e.g. peer support, relapse prevention), cross-training of staff, interdisciplinary treatment teams, specialised caseloads, and linkage with community mental health and social services. EBTs and programmatic adaptations have been successfully applied in community, jail and prison settings, and research indicates that integrated and structured treatment approaches significantly reduce reoffending and recidivism. Aftercare or reentry services can improve successful transition back into the community and improve offender outcomes. Risk assessment and structured assessment can be used to match offenders to the appropriate level of care and intensity of services. Future research should include controlled trials that examine the effectiveness of integrated offender treatment programmes and their components on key outcomes that include recidivism, substance use, utilisation of behavioural health services and psychosocial functioning.     

The Adolescent Community Reinforcement Approach (A-CRA) as a Model Paradigm for the Management of Adolescents With Substance Use Disorders and Co-Occurring Psychiatric Disorders

ABSTRACT. Background: Integrated treatment for youth with substance use disorders (SUDs) and co-occurring psychiatric disorders is recommended; however, there are few studies that have evaluated integrated treatment approaches. Methods: This paper includes a brief review of cognitive-behavioral and family therapies, since they have been demonstrated to be effective treatments for the disorders that commonly co-occur with substance use. It also describes how an integrated treatment paradigm has been implemented using one Empirically Supported Treatment, the Adolescent Community Reinforcement Approach (A-CRA). Results: There is existing research that supports the use of several A-CRA procedures to treat substance use and commonly co-occurring psychiatric disorders. Conclusions: In the absence of further research, it is reasonable in the interim to train clinicians in treatments that incorporate components that have been found to be effective for both substance use and commonly co-occurring psychiatric disorders. These treatments can then be adapted as needed based on an individual youth's set of problems. Further research is needed to test treatments for various combinations of SUDs and psychiatric disorders (i.e., depression, trauma-related problems, conduct disorder/behavior problems, and attention-deficit/hyperactivity disorder [ADHD]).     

Treatment Guidelines for Substance Use Disorders and Serious Mental Illnesses: Do They Address Co-Occurring Disorders?

Practice guidelines are important tools for improving the delivery of evidence-based practices and reducing inappropriate variation in current treatment approaches. This study examined the degree to which guidelines targeted to the treatment of substance use disorders or serious mental illness address treatment of co-occurring disorders. Guidelines archived by the National Guideline Clearinghouse (NGC) were retrieved in December 2007 and content analyzed. Nineteen pertinent guidelines were identified, and 11 included recommendations regarding the assessment and/or treatment of co-occurring disorders. None of the guidelines making recommendations for treatment of co-occurring disorders included outcomes that clearly targeted both substance use and mental health disorders. Limitations and implications of this study are noted.     

Public health care perspectives for the 1990s: What are the options?

Abstract

Despite the high quality of the American health care system at its best, effective service delivery and particularly the integration of substance abuse treatment, mental health services, HIV/AIDS services, and primary care is a serious and continuing problem. The Primary Care/Substance Abuse Linkage Initiative is the central focus of a major Federal effort to improve the integration of health care services. The planning for this initiative is described as are several classes of major barriers to achieving its objectives. These include: (1) issues of health care reimbursement, (2) problems of professional and public attitudes toward alcohol and drug dependency and its treatment, (3) substance abuse treatment service deficiencies, and (4) cultural insensitivity in the planning, administration, and delivery of services to ethnic and racial minorities. A Secretarial Conference and future plans for translating the concept of integrated treatment into a nationwide treatment reality are outlined.     

A cognitive behavioral therapy for co-occurring substance use and posttraumatic stress disorders

Co-occurring posttraumatic stress disorder (PTSD) is prevalent in addiction treatment programs and a risk factor for negative outcomes. Although interventions have been developed to address substance use and PTSD, treatment options are needed that are effective, well tolerated by patients, and potentially integrated with existing program services. This paper describes a cognitive behavioral therapy (CBT) for PTSD that was adapted from a treatment for persons with severe mental illnesses and PTSD in community mental health settings. The new adaptation is for patients in community addiction treatment with co-occurring PTSD and substance use disorders. In this study, 5 community therapists delivered the CBT for PTSD. Outcome data are available on 11 patients who were assessed at baseline, post-CBT treatment, and at a 3-month follow-up post-treatment. Primary outcomes were substance use, PTSD severity, and retention, of which all were favorable for patients receiving the CBT for PTSD.     

Substance misuse trends in South Africa

This paper, the first in a series related to the Joint European South African Research Network in Anxiety Disorders programme, examines substance use trends in South Africa. Alcohol remains the substance with the greatest burden of harm. Yet, trends vary by region, with for example methamphetamine being a major driver of psychiatric and substance abuse treatment demand in the Western Cape province. Heroin use is increasing in several provinces, where rapid intervention is required to avoid an epidemic. In particular, the state (the main funder of drug services) urgently needs to provide opioid substitution treatment. Apart from an inadequate number of treatment services, barriers to treatment are high. Barriers are predominantly cost, transport and resource related. Services are also impacted by a small and inadequately trained workforce and poor integration with mental health services. To adequately intervene with substance use disorders, South Africa needs an evidence-based policy and service planning framework that forges linkages with the mental health service system.     

Long-Term Sobriety Strategies for Men With Co-occurring Disorders

Objective: Roughly half of people with severe mental disorders also experience a co-occurring substance use disorder, and recovery from both is a critical objective for health care services. While understanding of abstinence initiation has grown, the strategies people with co-occurring disorders use to maintain sobriety are largely unknown. This article reports strategies for relapse prevention as described by men with co-occurring disorders who achieved one or more years of sobriety. Methods: We analyzed semi-structured interviews conducted with a sample of 12 men with co-occurring psychosis and substance use disorder who achieved and maintained sobriety for at least one year, supplemented with demographic and diagnostic clinical record data. These men were participating in residential or outpatient treatment at a private, nonprofit integrated treatment clinic. Results: The 12 men were primarily Caucasian (91.7%) and unmarried (100%), and their ages ranged from 23 to 42 years. The two most common psychiatric disorders were schizoaffective disorder (n = 4, 33.3%) and bipolar disorder (n = 4, 33.3%), while the two most commonly misused substances were alcohol and cannabis. Qualitative analyses showed that participants maintained sobriety for at least one year by building a supportive community, engaging in productive activities, and carefully monitoring their own attitudes toward substances, mental health, and responsibility. Alcoholics Anonymous might act as a catalyst for building skills. Conclusions: People with co-occurring disorders who achieve sobriety use a variety of self-management strategies to prevent relapse—seeking support, activities, and a healthy mindset. The findings suggest a relapse prevention model that focuses on social networks, role functioning, and self-monitoring and conceptualizes self-care as critical to extending periods of wellness.     

Smoking Cessation Outcomes and Predictors Among Individuals With Co-occurring Substance Use and/or Psychiatric Disorders

Objective: Individuals with substance use and psychiatric disorders have a high prevalence of tobacco use disorders and are disproportionately affected by tobacco-related morbidity and mortality. However, it is unclear how having co-occurring disorders affects tobacco cessation. Our aim was to examine smoking cessation outcomes and relevant predictors of smoking cessation among smokers with substance use and/or psychiatric disorders. Methods: Data from medical records of 674 participants in a tobacco treatment program within mental health and addictions services in Vancouver, Canada, were analyzed. The 26-week treatment program included an 8-week structured behavioral counseling group, an 18-week support group, and 26 weeks of no-cost pharmacotherapy. Information on demographics, tobacco use and history, type of pharmacotherapy received, nicotine dependence, importance of and confidence in quitting smoking, expired carbon monoxide level, substance use and psychiatric disorder history, and total program visits were gathered. Results: Approximately 67% (n = 449) of participants had co-occurring substance use and psychiatric disorders, while 20% (n = 136) had substance use disorder only, 10% (n = 67) had psychiatric disorder only, and 3% (n = 22) had tobacco dependence only. Rates of tobacco cessation (i.e., 7-day point prevalence of abstinence verified by expired carbon monoxide of ≤8 ppm) by group in the 522 people who completed treatment were as follows: 38.2% for those with co-occurring disorders, 47.1% for those with tobacco dependence only, 47.1% for those with substance use disorder only, and 41.8% for those with psychiatric disorder only. Length of treatment was a significant predictor of smoking cessation for those with co-occurring disorders and substance use disorder only. In the final stratified multivariate analysis, for individuals with co-occurring disorders, having an opiate use disorder (as compared to an alcohol use disorder) and higher nicotine dependence scores at baseline were predictive of poor cessation outcomes, while greater length of treatment was predictive of successful smoking cessation. Conclusions: Tobacco cessation treatment for individuals with co-occurring substance use and psychiatric disorders is likely to be as effective as for smokers with either disorder alone. Treatment duration predicts success among these smokers so strategies to enhance engagement and retention are needed.     

A review of research on residential programs for people with severe mental illness and co-occurring substance use disorders

Substance use disorder is the most common and clinically significant co-morbidity among clients with severe mental illnesses, associated with poor treatment response, homelessness and other adverse outcomes. Residential programs for clients with dual disorders integrate mental health treatment, substance abuse interventions, housing and other supports. Ten controlled studies suggest that greater levels of integration of substance abuse and mental health services are more effective than less integration. Because the research is limited by methodological problems, further research is needed to establish the effectiveness of residential programs, to characterize important program elements, to establish methods to improve engagement into and retention in residential programs and to clarify which clients benefit from this type of service.

The Integrated Co-Occurring Treatment (ICT) Model

Abstract

While integrated treatment programs have been developed and researched nationally for adults with co-occurring disorders of substance abuse and mental illness, little movement has been made on developing and field testing integrated programs that address the needs of youth with co-occurring disorders. This article will present one treatment model that has been developed and piloted in Ohio. The Integrated Co-Occurring Treatment (ICT) model focuses on youth with co-occurring disorders of mental health and substance abuse who have also been involved with the juvenile justice system. To date, the use of the ICT model has resulted in positive outcomes for both the youth and their     

Development and initial feasibility of an organizational measure of behavioral health integration in medical care settings

In the advent of health care reform, models are sought to integrate behavioral health and routine medical care services. Historically, the behavioral health specialty has not itself been integrated, but instead bifurcated by substance use and mental health across treatment systems, care providers and even research. With the present opportunity to transform the health care delivery system, it is incumbent upon policymakers, researchers and clinicians to avoid repeating this historical error, and provide integrated behavioral health services in medical contexts. An organizational measure designed to assess this capacity is described: the Dual Diagnosis Capability in Health Care Settings (DDCHCS). The DDCHCS was used to assess a sample of federally-qualified health centers (N = 13) on the degree of behavioral health integration. The measure was found to be feasible and sensitive to detecting variation in integrated behavioral health services capacity. Three of the 13 agencies were dual diagnosis capable, with significant variation in DDCHCS dimensions measuring staffing, treatment practices and program milieu. In general, mental health services were more integrated than substance use. Future research should consider a revised version of the measure, a larger and more representative sample, and linking organizational capacity with patient outcomes.     

Predictors of Residential Treatment Retention among Individuals with Co-Occurring Substance Abuse and Mental Health Disorders

Abstract

A significant number of individuals with co-occurring substance abuse and mental health disorders do not engage, stay, and/or complete residential treatment. The purpose of this study is to identify factors during the initial phase of treatment which predict retention in private residential treatment for individuals with co-occurring substance use and mental health disorders. The participants were 1,317 individuals with co-occurring substance abuse and mental health disorders receiving treatment at three residential treatment centers located in Memphis, TN, Malibu, CA, and Palm Springs, CA. Bivariate analysis and logistic regression were utilized to identify factors that predict treatment retention at 30 days. The findings indicate a variety of factors including age, gender, types of drug, Addiction Severity Index Medical and Psychiatric scores, and readiness to change. These identified factors could be incorporated into pretreatment assessments, so that programs can initiate preventive measures to decrease attrition and improve treatment outcomes.     

Contrasting the Views of Substance Misuse and Mental Health Treatment Providers on Treating the Dually Diagnosed

Service delivery to dually diagnosed individuals is often impeded by the divergent treatment approaches used by mental health and substance misuse treatment providers. This paper describes findings from a survey of mental health and substance misuse treatment program administrators and staff in Los Angeles County (n=275) on their views about treating the dually diagnosed. All groups agreed about the challenges of treating dually diagnosed patients; however, there were differences both between and within providers in the two treatment systems on other aspects of treatment. The findings are discussed within the context of clinical and programmatic efforts to improve service delivery to the dually diagnosed.     

Developing an integrated treatment for substance use and depression using cognitive–behavioral therapy

Providing a unified treatment approach to meet the substance abuse and mental health needs of clients is the preferred model for addressing co-occurring disorders. We developed a group-based cognitive-behavioral (CBT) integrated treatment for depression and substance use disorders (SUD) that could be delivered by counselors in SUD treatment settings and evaluated its feasibility and acceptability. We conducted an in-depth case study examining one implementation of the treatment using 15 focus groups with clients (n = 7) and semistructured interviews with counselors (n = 2) and administrators (n = 3). Using CBT as a treatment approach to integrate the treatment was widely accepted by clients, counselors, and administrators. Clients stated the treatment was applicable to multiple aspects of their lives and allowed them to recognize their clinical improvements over time. Counselors and administrators discussed challenges for long-term feasibility. Key decisions used to develop the treatment and recommendations for implementing integrated care in SUD settings are discussed.
