Psychosocial treatments for people with co-occurring severe mental illness and substance misuse: systematic review

Patterns of substance use recovery following residential treatment: A repeated measures latent profile analysis

INTRODUCTION

Ongoing improvement to residential treatment for substance use disorders is critical as it typically targets people with the highest need. Assessing multiple recovery indicators, such as cravings and mental health, at intake and following discharge is important in evaluating treatment effectiveness. To refine services, research should explore whether there are subgroups of individuals with different patterns of recovery following treatment.

METHODS

Participants (n = 554) were attending Australian Salvation Army residential treatment services for substance use issues. Data were collected by surveys at intake and 3-month post-discharge ('early recovery'). Recovery indicators were cravings, confidence to resist substance use and the Depression, Anxiety and Stress Scale. Subgroups of individuals based on these recovery indicators ('profiles') were identified using repeated measures latent profile analysis.

RESULTS

Five profiles were identified, three profiles improved over time (81.4%) and two (18.6%) deteriorated across all indicators. These two profiles had the poorest mental health and addiction scores at intake and reported shorter time in treatment compared to the three profiles showing improvement. There were no demographic or substance type differences between profiles.

DISCUSSION AND CONCLUSIONS

By considering initial severity and multiple recovery indicators at early recovery, this study suggests that individuals at-risk of poor early recovery can be identified at intake. This opens opportunities for tailored treatment approaches to address both mental health and substance use, thereby potentially improving treatment outcomes and reducing the risk of relapse.

Patterns of Self-Reported Mental Health Symptoms and Treatment among People Booked into a Large Metropolitan County Jail

The Brief Jail Mental Health Screen (BJMHS) is one of the most well-known and frequently used tools to conduct routine mental health screening at jail intake. In prior research, the BJMHS results typically have been evaluated overall (i.e., yes/no positive screen). However, there is heterogeneity in symptom presentation and treatment histories among people with serious mental illness, and there are potential consequences of this heterogeneity for mental health administration and policy in jails. We conducted a latent class analysis of BJMHS item-level results using administrative data for 37,998 people booked into a southeastern, metropolitan, U.S. county jail over a 3.5-year period. A 4-class solution provided the best fitting and most interpretable model. The largest class (89.5%) comprised people unlikely to report symptoms or treatment histories (limited symptoms). The next class comprised people who were unlikely to report ongoing symptoms but reported medication and hospitalization (managed symptoms). The third class (2.5%) included people likely to report feeling useless/sinful, prior hospitalization, and current psychiatric medication (depressive symptoms). The fourth class (1.0%) comprised people likely to report thought control, paranoia, feeling useless/sinful, medication, and hospitalization (psychotic symptoms). Controlling for sociodemographic and booking characteristics, people in the managed, depressive, and psychotic symptoms classes had significantly longer jail stays compared to those in the limited symptoms class. People in the managed and depressive symptoms classes were at heightened risk of re-arrest compared to the limited symptoms class. Findings can inform case prioritization and the allocation of resources to support efficient and effective jail-based mental health services.

Effectiveness of residential treatment services for veterans with substance use disorders: A propensity score matching evaluation

BACKGROUND

Prior reviews of substance use disorder (SUD) treatment have found mixed support for residential level of care but are limited by methodology problems and the ethical concerns of randomizing patients with severe SUD to lower levels of care.

METHODS

The present study is the first to use a large archival SUD residential sample with a matched comparison group and one-year follow-up period to examine the benefits of residential treatment provided to adults clinically assessed as warranting SUD residential care. We used propensity score matching in our sample (N = 6177) of veterans with a SUD who were screened and accepted for Veterans Affairs (VA) SUD residential treatment between January 1st, 2019 and June 30th, 2019.

RESULTS

We found evidence that VA SUD residential treatment saves veteran lives with an average 66% all-cause mortality risk reduction during the study period (b = -1.09, exp(b) = 0.34, p <0.001). Medium-to-large residential pre- to post-treatment self-reported mental health and SUD symptom improvements (|SMDrobust| = 0.54-0.93) were sustained by one-year post-screening. These residential treatment improvements were significantly larger than estimated counterfactual outcomes across self-reported SUD and stress disorder symptoms at one-year post-screening (ps <0.001). We found mixed behavioral, service utilization, and other self-reported mental health outcomes.

CONCLUSIONS

We conclude that VA SUD residential treatment is an effective level of care for veterans warranting residential care particularly for SUD symptom improvements and reductions in mortality risk.

Substance use, risk behaviours and well-being after admission to a quasi-residential abstinence-based rehabilitation programme: 4-year follow-up

BACKGROUND

Tackling Scotland's drug-related deaths and improving outcomes from substance misuse treatments, including residential rehabilitation, is a national priority.

AIMS

To analyse and report outcomes up to 4 years after attendance at a substance misuse residential rehabilitation programme (Lothians and Edinburgh Abstinence Programme).

METHOD

In total, 145 participants were recruited to this longitudinal quantitative cohort study of an abstinence-based residential rehabilitation programme based on the therapeutic community model; 87 of these participants were followed up at 4 years. Outcomes are reported for seven subsections of the Addiction Severity Index-X (ASI-X), together with frequency of alcohol use, heroin use, injecting drug use and rates of abstinence from substances of misuse.

RESULTS

Significant improvement in most outcomes at 4 years compared with admission scores were found. Completing the programme was associated with greater rates of abstinence, reduced alcohol use and improvements in alcohol status score (Mann-Whitney U = 626, P = 0.013), work satisfaction score (U = 596, P = 0.016) and psychiatric status score (U = 562, P = 0.007) on the ASI-X, in comparison with non-completion. Abstinence rates improved from 12% at baseline to 48% at 4 years, with the rate for those completing the programme increasing from 14.5% to 60.7% (χ²(2, 87) = 9.738, P = 0.002). Remaining abstinent from substances at follow-up was associated with better outcomes in the medical (U = 540, P < 0.001), psychiatric (U = 273.5, P < 0.001) and alcohol (U = 322.5, P < 0.001) subsections of the ASI-X.

CONCLUSIONS

Attending this abstinence-based rehabilitation programme was associated with positive changes in psychological and social well-being and harm reduction from substance use at 4-year follow-up, with stability of change from years 1 to 4.

Social work in alcohol and other drug service navigation: supporting social complexity in dual diagnosis

Purpose

Many people with dual diagnosis present with social complexity that impedes service access. The role of social work support in such service navigation is poorly understood. This study aims to characterise client presentations to an Australian telephone-based social work alcohol and other drug (AOD) service navigation and linkage program, with consideration of presentation complexity compared between those clients who present with or without self-reported mental health (MH) concerns and a history of MH diagnoses, to identify differences in baseline characteristics, and linkage outcomes.

Design/methodology/approach

A retrospective audit was conducted of routinely collected clinical information from a six-month period, selected to capture the social and health challenges experienced during the mid-pandemic period (mid-2021) in Victoria, Australia, during which a number of lockdowns resulted in a reliance on telephone-based services. The audit focused on client and presentation characteristics, and compared clients with and without a history of co-occurring MH and AOD concerns.

Findings

It was found that three in four people accessing an Australian telephone-based AOD service navigation and linkage program presented with dual diagnosis. Individuals with dual diagnosis required more support from the service compared to those without a co-occurring MH disorder; but overall, were just as likely to achieve a successful linkage to services, when offered holistic, long-term social work support.

Originality/value

This study focused on the role of social workers in this service navigation program in supporting individuals with complexity. It also highlights the challenges in operationalising social complexity factors alongside clinical MH and AOD diagnoses, and points to the need for further research to guide future service development for this vulnerable client group.

Integrated vs non-integrated treatment outcomes in dual diagnosis disorders: A systematic review

Background

The incidence of dual diagnosis (DD) (i.e. substance use disorders [SUD] and co-occurring mental disorders) is widespread; however, they vary widely in permutation and combination. As a result, establishing effective and empirically supported interventions for this clinical population remains challenging.

Aim

This study aimed to examine current literature on the treatment outcomes for patients with DD.

Method

A systematic review of randomised controlled trials (RCTs) published between 2009 and 2018 was conducted for two broad intervention categories identified by the literature: non-integrated and integrated treatment. Multiple electronic databases were searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA).

Results

The search generated a total of 743 studies, of which 11 satisfied the inclusion criteria. These studies were thematically synthesised into two main analytical themes: 'treatment outcomes' and 'reported strengths and limitations of DD treatment'. Specifically, integrated treatment held an advantage over non-integrated treatment in significantly improving psychiatric symptomatology. However, no significant benefits were found between integrated and non-integrated treatment regarding substance misuse and treatment retention.

Conclusion

Overall, the results provided insufficient evidence to support the enhanced efficacy of integrated or non-integrated treatment over the other in treating patients with DD.

Contribution

The study's findings were used to provide recommendations to inform the clinical psychological service delivery of dual diagnosis treatment in South Africa and also to identify gaps in the literature and highlight areas for future research.

Prevalence of co-occurring mental illness and substance use disorder and association with overdose: a linked data cohort study among residents of British Columbia, Canada

AIMS

To estimate the treated prevalence of mental illness, substance use disorder (SUD) and dual diagnosis and the association between dual diagnosis and fatal and non-fatal overdose among residents of British Columbia (BC), Canada.

DESIGN

A retrospective cohort study using linked health, income assistance, corrections and death records.

SETTING

British Columbia (BC), Canada.

PARTICIPANTS

A total of 921 346 BC residents (455 549 males and 465 797 females) aged 10 years and older.

MEASUREMENTS

Hospital and primary-care administrative data were used to identify a history of mental illness only, SUD only, dual diagnosis or no history of SUD or mental illness (2010-14) and overdoses resulting in medical care (2015-17). We calculated crude incidence rates of non-fatal and fatal overdose by dual diagnosis history. Andersen-Gill and competing risks regression were used to examine the association between dual diagnosis and non-fatal and fatal overdose, respectively, adjusting for age, sex, comorbidities, incarceration history, social assistance, history of prescription opioid and benzodiazepine dispensing and region of residence.

FINDINGS

Of the 921 346 people in the cohort, 176 780 (19.2%), 6147 (0.7%) and 15 269 (1.7%) had a history of mental illness only, SUD only and dual diagnosis, respectively; 4696 (0.5%) people experienced 688 fatal and 6938 non-fatal overdoses. In multivariable analyses, mental illness only, SUD only and dual diagnosis were associated with increased rate of non-fatal [hazard ratio (HR) = 1.8, 95% confidence interval (CI) = 1.6-2.1; HR = 9.0, 95% CI = 7.0-11.5, HR = 8.7, 95% CI = 6.9-10.9, respectively] and fatal overdose (HR = 1.6, 95% CI = 1.3-2.0, HR = 4.3, 95% CI = 2.8-6.5, HR = 4.1, 95% CI = 2.8-6.0, respectively) compared with no history.

CONCLUSIONS

In a large sample of residents of British Columbia (Canada), approximately one in five people had sought care for a substance use disorder or mental illness in the past 5 years. The rate of overdose was elevated in people with a mental illness alone, higher again in people with a substance use disorder alone and highest in people with a dual diagnosis. The adjusted hazard rates were similar for people with substance use disorder only and people with a dual diagnosis.

Implementation of a Multi-Modal Training Program for the Management of Comorbid Mental Disorders in Drug and Alcohol Settings: Pathways to Comorbidity Care (PCC)

OBJECTIVES

We aimed to evaluate the impact of the Pathways to Comorbidity Care (PCC) training program for alcohol and other drugs (AOD) clinicians to improve the management of comorbidity.

METHODS

A controlled before-and-after study using PCC training was conducted across 6 matched sites in Australia including 35 clinicians. Controls received standard workplace training. PCC training included seminar presentations, workshops conducted by local "clinical champions," individual clinical supervision, and access to an online information portal. We examined (a) identification (screening, assessment) and treatment (treatment, referral) of comorbidity in practice (N = 10 clinical files per clinician), (b) self-efficacy, knowledge, and attitudes of clinicians.

RESULTS

Significant improvements were observed in the PCC group but not the control sites with regards to the rate of clinical files showing identification of comorbidity (+50% v -12% change from baseline, respectively; [X² (1, N = 340) = 35.29, p = .01] with only a trend for improvements in the rate of files demonstrating treatment of comorbidity [X² (1, N = 340) = 10.45, p = .06]. There were significant improvements in the PCC relative to the control group for clinician self-efficacy, F(1,33) = 6.40, p = .02 and knowledge and attitudes of comorbidity monitoring, F(1,33) = 8.745, p = .01.

CONCLUSIONS

The PCC training package may help improve identification of comorbidity, self-efficacy, and attitudes toward screening and monitoring of comorbidity in drug and alcohol settings.

Systematic review and meta-analyses of randomized control trials of the effectiveness of psychosocial interventions for homeless adults

AIMS

To evaluate the effect of psychosocial interventions for homeless adults on their psychosocial outcomes.

DESIGN

A systematic review and meta-analyses were performed for critical appraisal and synthesis of the included studies.

DATA SOURCES

A systematic search of studies published before 10 September 2018 was performed using PubMed, Cochrane Library, EMBASE, PsycINFO, and CINAHL.

REVIEW METHODS

The review included randomized controlled trials conducting psychosocial interventions and assessing psychosocial outcomes for homeless adults. After systematically describing study and intervention characteristics, we conducted meta-analyses by the type of outcome and subgroup meta-analyses by the type of intervention and outcome. Fourteen studies were included in this review and 11 were included in the meta-analyses.

RESULTS

A significant effect of psychosocial interventions in reducing anxiety and enhancing mental health status among homeless adults was noted.

CONCLUSION

The meta-analyses showed that psychosocial interventions may reduce anxiety and enhance the mental health status of homeless people. Specifically, we suggest that relaxation response training may be effective in improving anxiety and mental health status and cognitive behavioural therapy may reduce anxiety.

IMPACT

Although psychosocial interventions for homeless persons have been implemented for a decade, their impact for psychosocial outcomes among homeless adults has not been evaluated. This review suggest that psychosocial interventions may improve anxiety and mental health status among homeless adults. The findings of the present study may provide directions for developing psychosocial interventions to help vulnerable homeless adults in managing psychological outcomes.

Psychosocial interventions for people with both severe mental illness and substance misuse

BACKGROUND

Even low levels of substance misuse by people with a severe mental illness can have detrimental effects.

OBJECTIVES

To assess the effects of psychosocial interventions for reduction in substance use in people with a serious mental illness compared with standard care.

SEARCH METHODS

The Information Specialist of the Cochrane Schizophrenia Group (CSG) searched the CSG Trials Register (2 May 2018), which is based on regular searches of major medical and scientific databases.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing psychosocial interventions for substance misuse with standard care in people with serious mental illness.

DATA COLLECTION AND ANALYSIS

Review authors independently selected studies, extracted data and appraised study quality. For binary outcomes, we calculated standard estimates of risk ratio (RR) and their 95% confidence intervals (CIs) on an intention-to-treat basis. For continuous outcomes, we calculated the mean difference (MD) between groups. Where meta-analyses were possible, we pooled data using a random-effects model. Using the GRADE approach, we identified seven patient-centred outcomes and assessed the quality of evidence for these within each comparison.

MAIN RESULTS

Our review now includes 41 trials with a total of 4024 participants. We have identified nine comparisons within the included trials and present a summary of our main findings for seven of these below. We were unable to summarise many findings due to skewed data or because trials did not measure the outcome of interest. In general, evidence was rated as low- or very-low quality due to high or unclear risks of bias because of poor trial methods, or inadequately reported methods, and imprecision due to small sample sizes, low event rates and wide confidence intervals. 1. Integrated models of care versus standard care (36 months) No clear differences were found between treatment groups for loss to treatment (RR 1.09, 95% CI 0.82 to 1.45; participants = 603; studies = 3; low-quality evidence), death (RR 1.18, 95% CI 0.39 to 3.57; participants = 421; studies = 2; low-quality evidence), alcohol use (RR 1.15, 95% CI 0.84 to 1.56; participants = 143; studies = 1; low-quality evidence), substance use (drug) (RR 0.89, 95% CI 0.63 to 1.25; participants = 85; studies = 1; low-quality evidence), global assessment of functioning (GAF) scores (MD 0.40, 95% CI -2.47 to 3.27; participants = 170; studies = 1; low-quality evidence), or general life satisfaction (QOLI) scores (MD 0.10, 95% CI -0.18 to 0.38; participants = 373; studies = 2; moderate-quality evidence). 2. Non-integrated models of care versus standard care There was no clear difference between treatment groups for numbers lost to treatment at 12 months (RR 1.21, 95% CI 0.73 to 1.99; participants = 134; studies = 3; very low-quality evidence). 3. Cognitive behavioural therapy (CBT) versus standard care There was no clear difference between treatment groups for numbers lost to treatment at three months (RR 1.12, 95% CI 0.44 to 2.86; participants = 152; studies = 2; low-quality evidence), cannabis use at six months (RR 1.30, 95% CI 0.79 to 2.15; participants = 47; studies = 1; very low-quality evidence) or mental state insight (IS) scores by three months (MD 0.52, 95% CI -0.78 to 1.82; participants = 105; studies = 1; low-quality evidence). 4. Contingency management versus standard care We found no clear differences between treatment groups for numbers lost to treatment at three months (RR 1.55, 95% CI 1.13 to 2.11; participants = 255; studies = 2; moderate-quality evidence), number of stimulant positive urine tests at six months (RR 0.83, 95% CI 0.65 to 1.06; participants = 176; studies = 1) or hospitalisations (RR 0.21, 95% CI 0.05 to 0.93; participants = 176; studies = 1); both low-quality evidence. 5. Motivational interviewing (MI) versus standard care We found no clear differences between treatment groups for numbers lost to treatment at six months (RR 1.71, 95% CI 0.63 to 4.64; participants = 62; studies = 1). A clear difference, favouring MI, was observed for abstaining from alcohol (RR 0.36, 95% CI 0.17 to 0.75; participants = 28; studies = 1) but not other substances (MD -0.07, 95% CI -0.56 to 0.42; participants = 89; studies = 1), and no differences were observed in mental state general severity (SCL-90-R) scores (MD -0.19, 95% CI -0.59 to 0.21; participants = 30; studies = 1). All very low-quality evidence. 6. Skills training versus standard care At 12 months, there were no clear differences between treatment groups for numbers lost to treatment (RR 1.42, 95% CI 0.20 to 10.10; participants = 122; studies = 3) or death (RR 0.15, 95% CI 0.02 to 1.42; participants = 121; studies = 1). Very low-quality, and low-quality evidence, respectively. 7. CBT + MI versus standard care At 12 months, there was no clear difference between treatment groups for numbers lost to treatment (RR 0.99, 95% CI 0.62 to 1.59; participants = 327; studies = 1; low-quality evidence), number of deaths (RR 0.60, 95% CI 0.20 to 1.76; participants = 603; studies = 4; low-quality evidence), relapse (RR 0.50, 95% CI 0.24 to 1.04; participants = 36; studies = 1; very low-quality evidence), or GAF scores (MD 1.24, 95% CI -1.86 to 4.34; participants = 445; studies = 4; very low-quality evidence). There was also no clear difference in reduction of drug use by six months (MD 0.19, 95% CI -0.22 to 0.60; participants = 119; studies = 1; low-quality evidence).

AUTHORS' CONCLUSIONS

We included 41 RCTs but were unable to use much data for analyses. There is currently no high-quality evidence to support any one psychosocial treatment over standard care for important outcomes such as remaining in treatment, reduction in substance use or improving mental or global state in people with serious mental illnesses and substance misuse. Furthermore, methodological difficulties exist which hinder pooling and interpreting results. Further high-quality trials are required which address these concerns and improve the evidence in this important area.

The effectiveness of residential treatment services for individuals with substance use disorders: A systematic review

BACKGROUND

Residential treatment is a standard treatment for individuals with severe and complex substance use problems. However, there is limited evidence on best practice approaches to treatment in these settings. This review provides a comprehensive update on the evidence base for residential treatment, and directions for future research and clinical practice.

METHOD

A systematic review of all studies published between January 2013 and December 2018 was conducted. Public health and psychology databases (Medline, CINAHL, PsycARTICLES and PsycINFO) were systematically searched, and forward and backward snowballing were used to identify additional studies. Studies were included if they were quantitative, assessed the effectiveness of residential substance treatment programs for adults, were published in the English language and in peer-reviewed journals. The Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies was used to assess methodological quality.

RESULTS

Our search identified 23 studies. Eight were rated as methodologically strong, five as moderate and ten rated as weak. Quality ratings were impacted by attrition at follow-up and research design. Despite limitations, results provide moderate quality evidence for the effectiveness of residential treatment in improving outcomes across a number of substance use and life domains.

CONCLUSION

With caution, results suggest that best practice rehabilitation treatment integrates mental health treatment and provides continuity of care post-discharge. Future research and practice should focus on better collection of outcome data and conducting data linkage of key health, welfare and justice agency administrative data to enhance understanding of risk and recovery trajectories.

Effectiveness of Motivational Interviewing on adult behaviour change in health and social care settings: A systematic review of reviews

BACKGROUND

The challenge of addressing unhealthy lifestyle choice is of global concern. Motivational Interviewing has been widely implemented to help people change their behaviour, but it is unclear for whom it is most beneficial. This overview aims to appraise and synthesise the review evidence for the effectiveness of Motivational Interviewing on health behaviour of adults in health and social care settings.

METHODS

A systematic review of reviews. Methods were pre-specified and documented in a protocol (PROSPERO-CRD42016049278). We systematically searched 7 electronic databases: CDSR; DARE; PROSPERO; MEDLINE; CINAHL; AMED and PsycINFO from 2000 to May 2018. Two reviewers applied pre-defined selection criteria, extracted data using TIDIER guidelines and assessed methodological quality using the ROBIS tool. We used GRADE criteria to rate the strength of the evidence for reviews including meta-analyses.

FINDINGS

Searches identified 5222 records. One hundred and four reviews, including 39 meta-analyses met the inclusion criteria. Most meta-analysis evidence was graded as low or very low (128/155). Moderate quality evidence for mainly short term (<6 months) statistically significant small beneficial effects of Motivational Interviewing were found in 11 of 155 (7%) of meta-analysis comparisons. These outcomes include reducing binge drinking, frequency and quantity of alcohol consumption, substance abuse in people with dependency or addiction, and increasing physical activity participation.

CONCLUSIONS

We have created a comprehensive map of reviews relating to Motivational Interviewing to signpost stakeholders to the best available evidence. More high quality research is needed to be confident about the effectiveness of Motivational Interviewing. We identified a large volume of low quality evidence and many areas of overlapping research. To avoid research waste, it is vital for researchers to be aware of existing research, and the implications arising from that research. In the case of Motivational Interviewing issues relating to monitoring and reporting fidelity of interventions need to be addressed.

Prevalence of comorbid substance use in schizophrenia spectrum disorders in community and clinical settings, 1990-2017: Systematic review and meta-analysis

BACKGROUND

Comorbidity is highly prevalent between substance use disorders (SUDs) and schizophrenia. This systematic review and meta-analysis estimated prevalence rates of SUDs in epidemiological and treatment-seeking patients diagnosed with schizophrenia or first episode psychosis.

METHODS

A literature search of Medline, EMBASE, PsycINFO and CINAHL databases was conducted from 1990 to 2017 inclusive. Prevalence of co-morbid SUDs and schizophrenia were extracted and odds ratios (ORs) were calculated using random effects meta-analysis. Combining like studies was dictated how authors reported substance use.

RESULTS

There were 123 included articles with a total sample size of 165,811 subjects that yielded six epidemiological studies, 11 national or state case-registry studies, 20 large cohort studies and 86 clinical studies using in- or out-patient samples. The prevalence of any SUD was 41.7%, followed by illicit drugs (27.5%), cannabis (26.2%), alcohol (24.3%) and stimulant use (7.3%). Meta-analysis showed the pooled variance of any SUD in males was 48% which was significantly higher than that for females with schizophrenia (22.1%, OR 3.43, 95% CI 3.01, 3.92). Patients with SUD had an earlier age of onset of schizophrenia. Meta-regression showed prevalence increased over time for illicit drugs but not for other substances, including alcohol.

CONCLUSIONS

The meta-analysis revealed that SUDs in schizophrenia is highly prevalent and rates have not changed over time. This indicates SUD are difficult to treat in this patient population and there is an urgent need for more informative studies to help develop better prevention, detection and treatment of SUDs in persons with schizophrenia and co-morbid disorders.

Translating Evidence-Based Practice for Managing Comorbid Substance Use and Mental Illness Using a Multimodal Training Package

OBJECTIVE

Comorbid mental health and substance use problems are highly prevalent in substance use treatment settings and generally lead to poorer treatment outcomes. Pathways to Comorbidity Care (PCC) is a multimodal training program developed to encourage an integrated service approach to improve clinicians capacity to identify and manage comorbid substance use and mental health outcomes within public drug and alcohol treatment settings.

METHODS

In this paper we describe the concepts underlying the PCC package and the use of implementation science to assess and overcome potential barriers, including clinicians preferences, knowledge about best practice, and professional culture.

RESULTS

The training components include didactic seminars, group workshops run by a local clinical champion on relevant subjects such as motivational interviewing and cognitive behavioral therapy, individual clinical consultation, and feedback with a senior clinical psychologist. The PCC also includes an online portal containing comorbidity resources including manuals, guidelines, and booster webinars. Finally, we describe the evaluation of PCC implementation.

CONCLUSIONS

Drug and alcohol services need to be equipped to treat the majority of comorbid mental health conditions in their clients. We anticipate that this multimodal training package, which applies the principles of implementation science, will facilitate effective and integrated care for these vulnerable clients.

What works in inclusion health: overview of effective interventions for marginalised and excluded populations

Inclusion health is a service, research, and policy agenda that aims to prevent and redress health and social inequities among the most vulnerable and excluded populations. We did an evidence synthesis of health and social interventions for inclusion health target populations, including people with experiences of homelessness, drug use, imprisonment, and sex work. These populations often have multiple overlapping risk factors and extreme levels of morbidity and mortality. We identified numerous interventions to improve physical and mental health, and substance use; however, evidence is scarce for structural interventions, including housing, employment, and legal support that can prevent exclusion and promote recovery. Dedicated resources and better collaboration with the affected populations are needed to realise the benefits of existing interventions. Research must inform the benefits of early intervention and implementation of policies to address the upstream causes of exclusion, such as adverse childhood experiences and poverty.

Multistrategy childcare-based intervention to improve compliance with nutrition guidelines versus usual care in long day care services: a study protocol for a randomised controlled trial

INTRODUCTION

Interventions to improve child diet are recommended as dietary patterns developed in childhood track into adulthood and influence the risk of chronic disease. For child health, childcare services are required to provide foods to children consistent with nutrition guidelines. Research suggests that foods and beverages provided by services to children are often inconsistent with nutrition guidelines. The primary aim of this study is to assess, relative to a usual care control group, the effectiveness of a multistrategy childcare-based intervention in improving compliance with nutrition guidelines in long day care services.

METHODS AND ANALYSIS

The study will employ a parallel group randomised controlled trial design. A sample of 58 long day care services that provide all meals (typically includes 1 main and 2 mid-meals) to children while they are in care, in the Hunter New England region of New South Wales, Australia, will be randomly allocated to a 6-month intervention to support implementation of nutrition guidelines or a usual care control group in a 1:1 ratio. The intervention was designed to overcome barriers to the implementation of nutrition guidelines assessed using the theoretical domains framework. Intervention strategies will include the provision of staff training and resources, audit and feedback, ongoing support and securing executive support. The primary outcome of the trial will be the change in the proportion of long day care services that have a 2-week menu compliant with childcare nutrition guidelines, measured by comprehensive menu assessments. As a secondary outcome, child dietary intake while in care will also be assessed. To assess the effectiveness of the intervention, the measures will be undertaken at baseline and ∼6 months postbaseline.

ETHICS AND DISSEMINATION

The study was approved by the Hunter New England Human Research Ethics Committee. Study findings will be disseminated widely through peer-reviewed publications.

Motivational interviewing and interaction skills training for parents of young adults with recent-onset schizophrenia and co-occurring cannabis use: 15-month follow-up

BACKGROUND

There is a clear need for effective interventions to reduce cannabis use in patients with first-episode psychosis. This follow-up of a randomized trial examined whether an intervention for parents, based on motivational interviewing and interaction skills (Family Motivational Intervention, FMI), was more effective than routine family support (RFS) in reducing cannabis use in patients with recent-onset schizophrenia.

METHOD

In a single-blind trial with 75 patients in treatment for recent-onset schizophrenia, 97 parents were randomly assigned to either FMI or RFS. Assessments were conducted at baseline and at 3 and 15 months after the interventions had been ended. Analyses were performed on an intention-to-treat basis using mixed-effect regression models.

RESULTS

From baseline to the 15-month follow-up, there was a significantly greater reduction in FMI compared to RFS in patients' quantity (p = 0.01) and frequency (p < 0.01) of cannabis use. Patients' craving for cannabis use was also significantly lower in FMI at 15 months follow-up (p < 0.01). Both groups improved in parental distress and sense of burden; however, only FMI parents' appraisal of patients' symptoms showed further improvement at the 15-month follow-up (p < 0.05).

CONCLUSIONS

The results support the sustained effectiveness of FMI in reducing cannabis use in patients with recent-onset schizophrenia at 15 months follow-up. Findings were not consistent with regard to the long-term superiority of FMI over RFS in reducing parents' distress and sense of burden.

The interaction of active substance use, depression, and antiretroviral adherence in methadone maintenance

BACKGROUND

Adherence to highly active antiretroviral therapy (HAART) remains crucial in successfully treating HIV. While active substance use and depression are both associated with each other and with HAART nonadherence, little is known about their interaction. An understanding of the interaction of substance use and depressive symptoms on HAART adherence can inform adherence-enhancing interventions as well as interventions that target substance use and depression.

PURPOSE

We tested an interaction between substance use and depression on HAART adherence among methadone maintenance patients.

METHOD

We assessed substance use, depressive symptoms, and HAART adherence among 100 HIV-infected individuals receiving methadone maintenance in The Bronx, New York. Regressions were performed on adherence using an interaction term comprised of substance use and depressive symptoms. MODPROBE was used to assess significant interactions.

RESULTS

Any use of illicit substances was associated with HAART nonadherence (p = 0.043). Cannabis was the single substance of abuse most strongly associated with nonadherence (p = 0.003). Depressive symptoms approached significance in bivariate analysis (p = 0.066). In regression analysis, a significant interaction was found between illicit substance use and depressive symptoms [OR (95% CI) 1.23 (1.06-1.44), p = 0.007], where illicit substance use was associated with nonadherence in individuals with lower depressive symptoms, but not among those with depressive symptoms at higher levels. No individual substances interacted with depressive symptoms on adherence.

CONCLUSION

Though substance use and depressive symptoms interacted on HAART adherence, they did not have a synergistic effect. Continued substance use (51% of the sample) suggests an unmet need for treatment, even in methadone maintenance. Further examinations of the interplay of substance use and depression on HAART adherence are warranted.

Delivery of a mainstreaming treatment model towards co-existing difficulties: a brief exploration of practitioners’ understanding, views and reported experiences

Purpose

– The purpose of this paper is to describe the delivery of a mainstreaming model within a public sector, mental health (National Health Service (NHS)) organisation. The model promotes the inclusivity of a spectrum of presentations from co-existing moderate anxiety and depression to severe mental disorder (psychosis) and problematic substance and alcohol use.

Design/methodology/approach

– This paper introduces the delivery of three collective approaches, termed the “three essential elements” to support a mainstreaming treatment model, facilitated by a “Dual Diagnosis Lead”. The model encompasses; a “direct access” referral pathway, joint collaboration with practitioners and the delivery of a “Dual Diagnosis” training programme. An independent evaluation was commissioned to explore eight mental health and substance misuse practitioners’ views and experiences in relation to the impact of the mainstreaming model. This paper also considers feedback from 230 course participants attending a one day “Dual Diagnosis” training programme.

Findings

– This paper suggests that practitioners may benefit from the implementation of the mainstreaming approach and the delivery of this approach could be moving “Dual Diagnosis” interventions closer to mainstream practice.

Research limitations/implications

– The limitations of the mainstreaming model are acknowledged in relation to the generalisation of practitioners’ views and reported experiences.

Originality/value

– This paper offers a description of the delivery of a mainstreaming model involving the “three essential elements”. The model provides a useful insight and demonstrates the possibilities which may be achieved when attempting to implement a mainstreaming treatment approach within mainstream mental health and drug and alcohol services.

S3 guideline on psychosocial therapies in severe mental illness: evidence and recommendations

The burden of severe and persistent mental illness is high. Beside somatic treatment and psychotherapeutic interventions, treatment options for patients with severe mental illness also include psychosocial interventions. This paper summarizes the results of a number of systematic literature searches on psychosocial interventions for people with severe mental illness. Based on this evidence appraisal, recommendations for the treatment of people with severe mental illness were formulated and published in the evidence-based guideline series of the German Society for Psychiatry, Psychotherapy and Neurology (DGPPN) as an evidence-based consensus guideline ("S3 guideline"). Recommendations were strongly based on study results, but used consensus processes to consider external validity and transferability of the recommended practices to the German mental healthcare system. A distinction is made between system-level interventions (multidisciplinary team-based psychiatric community care, case management, vocational rehabilitation and participation in work life and residential care interventions) and single psychosocial interventions (psychoeducation, social skills training, arts therapies, occupational therapy and exercise therapy). There is good evidence for the efficacy of the majority of psychosocial interventions in the target group. The best available evidence exists for multidisciplinary team-based psychiatric community care, family psychoeducation, social skills training and supported employment. The present guideline offers an important opportunity to further improve health services for people with severe mental illness in Germany. Moreover, the guideline highlights areas for further research.

Dual recovery among people with serious mental illnesses and substance problems: a qualitative analysis

OBJECTIVE

Individuals with serious mental illnesses are more likely to have substance-related problems than those without mental health problems. They also face more difficult recovery trajectories as they cope with dual disorders. Nevertheless, little is known about individuals' perspectives regarding their dual recovery experiences.

METHODS

This qualitative analysis was conducted as part of an exploratory mixed-methods study of mental health recovery. Members of Kaiser Permanente Northwest (a group-model, not-for-profit, integrated health plan) who had serious mental illness diagnoses were interviewed four times over two years about factors affecting their mental health recovery. Interviews were recorded, transcribed, and coded with inductively derived codes. Themes were identified by reviewing text coded "alcohol or other drugs."

RESULTS

Participants (N = 177) had diagnosed schizophrenia/schizoaffective disorder (n = 75, 42%), bipolar I/II disorder (n = 84, 48%), or affective psychosis (n = 18, 10%). At baseline, 63% (n = 112) spontaneously described addressing substance use as part of their mental health recovery. When asked at follow-up, 97% (n = 171) provided codeable answers about substances and mental health. We identified differing pathways to recovery, including through formal treatment, self-help groups or peer support, "natural" recovery (without the help of others), and continued but controlled use of alcohol. We found three overarching themes in participants' experiences of recovering from serious mental illnesses and substance-related problems: Learning about the effects of alcohol and drugs provided motivation and a foundation for sobriety; achieving sobriety helped people to initiate their mental health recovery processes; and achieving and maintaining sobriety built self-efficacy, self-confidence, improved functioning and a sense of personal growth. Non-judgmental support from clinicians adopting chronic disease approaches also facilitated recovery.

CONCLUSIONS

Irrespective of how people achieved sobriety, quitting or severely limiting use of substances was important to initiating and continuing mental health recovery processes. Substance abuse treatment approaches that are flexible, reduce barriers to engagement, support learning about effects of substances on mental health and quality of life, and adopt a chronic disease model of addiction may increase engagement and success. Peer-based support like Alcoholics or Narcotics Anonymous can be helpful for people with serious mental illnesses, particularly when programs accept use of mental health medications.

A review of treatment options for co-occurring methamphetamine use disorders and depression

Co-occurring methamphetamine use and depression interferes with treatment outcomes. Female methamphetamine users are known to have higher rates of depression than male methamphetamine users, although this is also true for the general population. There are limited treatment options for the management of depression among methamphetamine users. In this integrative review, we summarize data on treatment strategies for co-occurring depression and methamphetamine use disorders. English-language articles were identified from PsychINFO, CINAHL, PubMed, and Medline as well as from reference lists of key articles. Search terms included "methamphetamine," "depression," and "treatment." Research articles describing psychological (n = 3), pharmacological (n = 6), nutritional supplement (n = 1), and psychological combined with pharmacological (n = 3) approaches for the treatment of methamphetamine use or withdrawal and/or depression are included in this review. Psychological and combination of psychological with pharmacological approaches have not been shown to be effective in treating these co-occurring conditions. Antidepressants have been determined to be ineffective and/or to introduce side effects. Gender differences with response to treatment were examined in only one of the published studies. There is a large gap in knowledge regarding treatment of co-occurring methamphetamine use disorders and depression. Considering that female methamphetamine users experience higher rates of depression than men, a focus on gender-specific treatment approaches is warranted.

Predictors of substance use reduction in an epidemiological first-episode psychosis cohort

AIM

To assess the predictors of a significant decrease or cessation of substance use (SU) in a treated epidemiological cohort of first-episode psychosis (FEP) patients.

METHOD

Participants were FEP patients of the Early Psychosis Prevention and Intervention Centre in Australia. Patients' medical files were reviewed using a standardized file audit. Data on 432 patients with FEP and baseline co-morbid substance use disorder (SUD) were available for analysis. Predictors of reduction/cessation of SU at follow up were examined using logistic regression analyses.

RESULTS

In univariate analyses, a reduction/cessation of SU was predicted by baseline measures reflecting higher education, employment, accommodation with others, cannabis use disorder (CUD) only (rather than poly-SUDs), better global functioning and better premorbid social and occupational functioning, later age at onset of psychosis, and a diagnosis of non-affective psychosis. In multivariate analysis, CUD alone and better premorbid social and occupational functioning remained significant predictors.

CONCLUSIONS

Addressing SUDs and social and occupational goals in people with FEP may offer opportunities to prevent SUDs becoming more severe or entrenched. Further longitudinal research on recovery from SU and FEP is needed to disentangle directions of influence and identify key targets for intervention.

An outcomes study of eTherapy for dual diagnosis using Breaking Free Online

Purpose

– In recent years there has been a proliferation of computer-based psychotherapeutic interventions for common mental health difficulties. Building on this, a small number of such interventions have now been developed to address substance dependence, one of which is Breaking Free Online (BFO). A new “eTherapy” self-help service, which was set up by the UK mental health charity Self-Help Services, has provided access to BFO to service users presenting with comorbid mental health and substance misuse difficulties. The purpose of this paper is to evaluate a range of clinical outcomes in the first cohort of service users accessing this dual diagnosis service.

Design/methodology/approach

– A number of standardised psychometric assessments were conducted with service users at baseline and post-treatment at discharge from the service. Outcome data were available for 47 service users out of an original cohort of 74.

Findings

– Statistically significant improvements were found in terms of measures of social functioning, depression, anxiety, alcohol and drug use and social anxiety. Clinically relevant gains were also identified, with fewer service users reaching threshold scores for depression and anxiety at post-treatment compared to baseline. Effect sizes also indicated that the identified improvements across the psychometric measures were robust and significant.

Research limitations/implications

– These findings provide further support for the clinical effectiveness of BFO, and also provide evidence that an eTherapy self-help service may be appropriate for some individuals presenting with dual diagnosis. Further research is underway with larger and alternative clinical populations to examine the effectiveness of BFO and also this novel eTherapy self-help approach.

Originality/value

– This paper has provided initial data to support effectiveness of a novel eTherapy service for dual diagnosis.

Assertive community treatment and associations with substance abuse problems

This study examined the associations between substance abuse problems in severely mentally ill patients, outcome and Assertive Community Treatment (ACT) model fidelity. In a prospective longitudinal study, ACT model fidelity and patient outcomes were assessed in 20 outpatient treatment teams using the Health of the Nation Outcome Scales, Camberwell Assessment of Needs short appraisal schedule and measures of service use. Five hundred and thirty severely mentally ill patients participated in the study. Substance abuse problems were assessed three times during a 2-year follow-up period. This study found that among patients with severe mental illness, patients with an addiction problem had more serious psychosocial problems at baseline. Substance abuse problems showed improvement over time, but this was not associated with ACT model fidelity. The study indicates that investment by teams to improve a patient's psychosocial situation can lead to improvements on substance problems.

[Evidence-based interventions in psychiatric rehabilitation: which ones should we prioritized and why?]

OBJECTIVE

This critical literature review describes current evidence-based psychiatric rehabilitation interventions.

METHOD

A brief description of recent meta-analyses and (or) literature reviews is presented for each targeted intervention, along with their revelance for psychiatric rehabilitation and their limits.

RESULTS

The interventions presented include: family interventions, cognitive-behavioural therapy for psychosis, social skills training, cognitive remediation, integrated treatment for substance misuse and mental disorders, and supported employment programs.

CONCLUSIONS

The psychiatric rehabilitation interventions presented in this article not only are based on empirical evidence but also offer clinical tools support the recovery of people with a severe mental illness.

Randomized trial of intensive motivational interviewing for methamphetamine dependence

An intensive, 9-session motivational interviewing (IMI) intervention was assessed using a randomized clinical trial of 217 methamphetamine (MA) dependent individuals. Intensive motivational interviewing (IMI) was compared with a single standard session of MI (SMI) combined with eight nutrition education sessions. Interventions were delivered weekly over 2 months. All study participants also received standard outpatient group treatment three times per week. Both study groups showed significant decreases in MA use and Addiction Severity Index drug scores, but there were no significant differences between the two groups. However, reductions in Addiction Severity Index psychiatric severity scores and days of psychiatric problems during the past 30 days were found for clients in the IMI group but not the SMI group. SMI may be equally beneficial to IMI in reducing MA use and problem severity, but IMI may help alleviate co-occurring psychiatric problems that are unaffected by shorter MI interventions. Additional studies are needed to assess the problems, populations, and contexts for which IMI is effective.

Psychosocial interventions for people with both severe mental illness and substance misuse

BACKGROUND

Even low levels of substance misuse by people with a severe mental illness can have detrimental effects.

OBJECTIVES

To assess the effects of psychosocial interventions for reduction in substance use in people with a serious mental illness compared with standard care.

SEARCH METHODS

For this update (2013), the Trials Search Co-ordinator of the Cochrane Schizophrenia Group (CSG) searched the CSG Trials Register (July 2012), which is based on regular searches of major medical and scientific databases. The principal authors conducted two further searches (8 October 2012 and 15 January 2013) of the Cochrane Database of Systematic Reviews, MEDLINE and PsycINFO. A separate search for trials of contingency management was completed as this was an additional intervention category for this update.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing psychosocial interventions for substance misuse with standard care in people with serious mental illness.

DATA COLLECTION AND ANALYSIS

We independently selected studies, extracted data and appraised study quality. For binary outcomes, we calculated standard estimates of relative risk (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis. For continuous outcomes, we calculated the mean difference (MD) between groups. For all meta-analyses we pooled data using a random-effects model. Using the GRADE approach, we identified seven patient-centred outcomes and assessed the quality of evidence for these within each comparison.

MAIN RESULTS

We included 32 trials with a total of 3165 participants. Evaluation of long-term integrated care included four RCTs (n = 735). We found no significant differences on loss to treatment (n = 603, 3 RCTs, RR 1.09 CI 0.82 to 1.45, low quality of evidence), death by 3 years (n = 421, 2 RCTs, RR 1.18 CI 0.39 to 3.57, low quality of evidence), alcohol use (not in remission at 36 months) (n = 143, 1 RCT, RR 1.15 CI 0.84 to 1.56,low quality of evidence), substance use (n = 85, 1 RCT, RR 0.89 CI 0.63 to 1.25, low quality of evidence), global assessment of functioning (n = 171, 1 RCT, MD 0.7 CI 2.07 to 3.47, low quality of evidence), or general life satisfaction (n = 372, 2 RCTs, MD 0.02 higher CI 0.28 to 0.32, moderate quality of evidence).For evaluation of non-integrated intensive case management with usual treatment (4 RCTs, n = 163) we found no statistically significant difference for loss to treatment at 12 months (n = 134, 3 RCTs, RR 1.21 CI 0.73 to 1.99, very low quality of evidence).Motivational interviewing plus cognitive behavioural therapy compared to usual treatment (7 RCTs, total n = 878) did not reveal any advantage for retaining participants at 12 months (n = 327, 1 RCT, RR 0.99 CI 0.62 to 1.59, low quality of evidence) or for death (n = 493, 3 RCTs, RR 0.72 CI 0.22 to 2.41, low quality of evidence), and no benefit for reducing substance use (n = 119, 1 RCT, MD 0.19 CI -0.22 to 0.6, low quality of evidence), relapse (n = 36, 1 RCT, RR 0.5 CI 0.24 to 1.04, very low quality of evidence) or global functioning (n = 445, 4 RCTs, MD 1.24 CI 1.86 to 4.34, very low quality of evidence).Cognitive behavioural therapy alone compared with usual treatment (2 RCTs, n = 152) showed no significant difference for losses from treatment at 3 months (n = 152, 2 RCTs, RR 1.12 CI 0.44 to 2.86, low quality of evidence). No benefits were observed on measures of lessening cannabis use at 6 months (n = 47, 1 RCT, RR 1.30 CI 0.79 to 2.15, very low quality of evidence) or mental state (n = 105, 1 RCT, Brief Psychiatric Rating Scale MD 0.52 CI -0.78 to 1.82, low quality of evidence).We found no advantage for motivational interviewing alone compared with usual treatment (8 RCTs, n = 509) in reducing losses to treatment at 6 months (n = 62, 1 RCT, RR 1.71 CI 0.63 to 4.64, very low quality of evidence), although significantly more participants in the motivational interviewing group reported for their first aftercare appointment (n = 93, 1 RCT, RR 0.69 CI 0.53 to 0.9). Some differences, favouring treatment, were observed in abstaining from alcohol (n = 28, 1 RCT, RR 0.36 CI 0.17 to 0.75, very low quality of evidence) but not other substances (n = 89, 1 RCT, RR -0.07 CI -0.56 to 0.42, very low quality of evidence), and no differences were observed in mental state (n = 30, 1 RCT, MD 0.19 CI -0.59 to 0.21, very low quality of evidence).We found no significant differences for skills training in the numbers lost to treatment by 12 months (n = 94, 2 RCTs, RR 0.70 CI 0.44 to 1.1, very low quality of evidence).We found no differences for contingency management compared with usual treatment (2 RCTs, n = 206) in numbers lost to treatment at 3 months (n = 176, 1 RCT, RR 1.65 CI 1.18 to 2.31, low quality of evidence), number of stimulant positive urine tests at 6 months (n = 176, 1 RCT, RR 0.83 CI 0.65 to 1.06, low quality of evidence) or hospitalisations (n = 176, 1 RCT, RR 0.21 CI 0.05 to 0.93, low quality of evidence).We were unable to summarise all findings due to skewed data or because trials did not measure the outcome of interest. In general, evidence was rated as low or very low due to high or unclear risks of bias because of poor trial methods, or poorly reported methods, and imprecision due to small sample sizes, low event rates and wide confidence intervals.

AUTHORS' CONCLUSIONS

We included 32 RCTs and found no compelling evidence to support any one psychosocial treatment over another for people to remain in treatment or to reduce substance use or improve mental state in people with serious mental illnesses. Furthermore, methodological difficulties exist which hinder pooling and interpreting results. Further high quality trials are required which address these concerns and improve the evidence in this important area.

Intensive motivational interviewing for women with concurrent alcohol problems and methamphetamine dependence

Motivational interviewing (MI) for the treatment of alcohol and drug problems is typically conducted over 1 to 3 sessions. The current work evaluates an intensive 9-session version of MI (Intensive MI) compared to a standard single MI session (Standard MI) using 163 methamphetamine (MA) dependent individuals. The primary purpose of this paper is to report the unexpected finding that women with co-occurring alcohol problems in the Intensive MI condition reduced the severity of their alcohol problems significantly more than women in the Standard MI condition at the 6-month follow-up. Stronger perceived alliance with the therapist was inversely associated with alcohol problem severity scores. Findings indicate that Intensive MI is a beneficial treatment for alcohol problems among women with MA dependence.

Social workers and delivery of evidence-based psychosocial treatments for substance use disorders

Social workers encounter individuals with substance use disorders (SUDs) in a variety of settings. With changes in health care policy and a movement toward integration of health and behavioral health services, social workers will play an increased role vis-á-vis SUD. As direct service providers, administrators, care managers, and policy makers, they will select, deliver, or advocate for delivery of evidence-based SUD treatment practices. This article provides an overview of effective psychosocial SUD treatment approaches. In addition to describing the treatments, the article discusses empirical support, populations for whom the treatments are known to be efficacious, and implementation issues.

Motivational interviewing and interaction skills training for parents to change cannabis use in young adults with recent-onset schizophrenia: a randomized controlled trial

BACKGROUND

Cannabis use by people with schizophrenia has been found to be associated with family distress and poor clinical outcomes. Interventions to reduce drug use in this patient group have had limited efficacy. This study evaluated the effectiveness of a novel intervention for parents of young adults with recent-onset schizophrenia consisting of family-based motivational interviewing and interaction skills (Family Motivational Intervention, FMI) in comparison with routine family support (RFS).

METHOD

In a trial with 75 patients who used cannabis and received treatment for recent-onset schizophrenia, 97 parents were randomly assigned to either FMI (n=53) or RFS (n=44). Assessments were conducted at baseline and 3 months after completion of the family intervention by an investigator who remained blind throughout the study about the assignment of the parents.

RESULTS

At follow-up, patients' frequency and quantity of cannabis use was significantly more reduced in FMI than in RFS (p<0.05 and p<0.04 respectively). Patients' craving for cannabis was also significantly reduced in FMI whereas there was a small increase in RFS (p=0.01). There was no difference between FMI and RFS with regard to patients' other substance use and general level of functioning. Both groups showed significant improvements in parental distress and sense of burden.

CONCLUSIONS

Training parents in motivational interviewing and interaction skills is feasible and effective in reducing cannabis use among young adults with recent-onset schizophrenia. However, FMI was not more effective than RFS in increasing patients' general level of functioning and in reducing parents' stress and sense of burden.

Psychiatric co-morbidity and substance use disorders: treatment in parallel systems or in one integrated system?

Psychiatric co-morbidity among substance users refers to the simultaneous presence of at least another psychiatric disorder in a person diagnosed with a substance use disorder. Co-morbid patients represent a substantial number of people in treatment and present greater disorder severity from both the clinical and social perspectives than those people diagnosed with only one type of disorder. We present an overview of the current state of the art concerning the choice of site of treatment, the kind of intervention, the length of such treatment, and future goals, aiming to establish a more effective intervention, and finally so as to further improve clinical outcomes.

Helping homeless individuals with co-occurring disorders: the four components

Homeless individuals with co-occurring disorders (CODs) of severe mental illness and substance use disorder are one of the most vulnerable populations. This article provides practitioners with a framework and strategies for helping this client population. Four components emerged from a literature review: (1) ensuring an effective transition for individuals with CODs from an institution (such as a hospital, foster care, prison, or residential program) into the community, a particularly important component for clients who were previously homeless, impoverished, or at risk of homelessness; (2) increasing the resources of homeless individuals with CODs by helping them apply for government entitlements or supported employment (3) linking homeless individuals to supportive housing, including housing first options as opposed to only treatment first options, and being flexible in meeting their housing needs; and (4) engaging homeless individuals in COD treatment, incorporating modified assertive community treatment, motivational interviewing, cognitive-behavioral therapy, contingency management, and COD specialized self-help groups.

Effectiveness of psychosocial intervention for children and adolescents with comorbid problems: a systematic review

BACKGROUND

  Comorbidity is common among child clinical samples. Reviews on effective intervention for comorbid problems are lacking.

METHOD

  Based on a literature search of three databases (PsycINFO, MEDLINE and ERIC), initial data analysis was carried out on 865 studies; of these,10 randomised trials fully met study inclusion criteria and were subject to final analysis, with quality assessments and effect sizes calculated.

RESULTS

  Overall, effect sizes for externalising (M = 1.12) and internalising (M = 1.09) outcomes were large. Effect sizes were large for family-based (M = 1.80) compared to individual (M = 0.78) and group-based (M = 0.54) interventions. Studies with homotypic comorbidity (M= 1.18) displayed larger treatment effect sizes than ones with heterotypic comorbidity (M = 0.54).

CONCLUSIONS

  While the overall quality ratings of the reviewed studies varied from mediocre to good, with a variety of measures used across studies to assess the same outcomes, findings suggest that current interventions are effective for reducing internalising and externalising problems in children with comorbidity. More substantive evidence for the beneficial effects of psychosocial interventions for children with comorbid problems may arise as more robust studies, which more explicitly address and describe comorbidity, become available.

Substance use disorder among people with first-episode psychosis: a systematic review of course and treatment

OBJECTIVE

People experiencing a first episode of psychosis frequently have co-occurring substance use disorders, usually involving alcohol and cannabis, which put them at risk for prolonged psychosis, psychotic relapse, and other adverse outcomes. Yet few studies of first-episode psychosis have addressed the course of substance use disorders and the response to specialized substance abuse treatments.

METHODS

The authors searched MEDLINE, PsycINFO, and other medical databases for English-language articles published between 1990 and 2009. Included studies addressed two research questions. First, do some clients become abstinent after a first episode of psychosis without specialized substance abuse treatments? Second, for clients who continue to use substances after a first episode of psychosis, does the addition of specialized substance abuse treatment enhance outcomes?

RESULTS

Nine studies without specialized substance abuse treatment and five with specialized substance abuse treatment assessed the course of substance use (primarily cannabis and alcohol) after a first episode of psychosis. Many clients (approximately half) became abstinent or significantly reduced their alcohol and drug use after a first episode of psychosis. The few available studies of specialized substance abuse treatments did not find better rates of abstinence or reduction.

CONCLUSIONS

Experience, education, treatment, or other factors led many clients to curtail their substance use disorders after a first episode of psychosis. Specialized interventions for others need to be developed and tested.

Why is better mental health care so elusive?

PURPOSE

There are numerous barriers to improving healthcare delivery. This article summarizes contemporary theories and research evidence to focus on ways to motivate change within the hospital system to provide better health care.

CONCLUSIONS

Understanding multidisciplinary team processes, recognizing hospitals as systems, and ascertaining the unit culture is a prerequisite for leaders and policy makers to improve mental health practices.

PRACTICE IMPLICATIONS

Finding ways to deliver better health care to people with a mental illness is a high priority, and nurses have a central role to play in this pursuit of excellence.
