A systematic review of psychosocial research on psychosocial interventions for people with co-occurring severe mental and substance use disorders

Integrating services for patients with mental and substance use disorders

“…As with others, our study suggests that there is no preferred model for the organization of care for co-occurring disorders; well-coordinated care with close communication between clinicians and treatment that takes full account of comorbidity can also have a significant impact on patients' health (Donald et al, 2005;Drake et al, 2008). An important and recent publication presents a thorough analysis of the various ways of integrating services, in terms of process and forms of integration, for a clientele with cooccurring disorders (Rush et al, 2008).…”

“…However, previous experiences have shown that these may not necessarily be suitable for all types of clientele nor for several forms of health systems organization, in particular because of the required restructuring of human and financial resources (SAMHSA, 2003). Furthermore, a systematic literature review shows that the superiority of these propositions has not been not demonstrated because of the heterogeneity of studies (lack of standardization, absence of fidelity assessment, diversity of patients, varying lengths of intervention, diversity of outcomes, and inconsistency of measures in current research; Drake et al, 2008). Recent studies on models of care show that patients' health seems to improve if they are treated in programs that provide specific services for cooccurring disorders (Grella & Stein, 2006), but they also underline the importance of adapting approaches to different types of conditions, as there is great heterogeneity in mental health diagnosis and substance consumptions (Tiet & Mausbach, 2007), which requires flexibility in the organization of care.…”

Substance Use Disorder Among People With First-Episode Psychosis: A Systematic Review of Course and Treatment

“…The negative outcomes associated with traditional approaches have led to integrated treatments designed to target co-occurring mental and substance use disorders concurrently in the same setting (36,37). Several reviews of experimental and quasi-experimental studies support different types of integrated treatment, including group counseling, contingency management, residential treatment, and motivational interventions combined with cognitive-behavioral treatment (38,39). …”

Managing cannabis use in people with severe mental illness: what can be done?

“…The most recent comprehensive review of psycho social interventions for people with cooccurring substance use disorder and severe mental illness assessed 45 controlled studies (Drake 2008). Consistent positive effects on substance misuse were found with three types of integrated intervention: group counselling, contingency management and longterm residential treatment.…”
