Treating comorbid substance use disorders in schizophrenia
This literature review examines the pharmacological and psychosocial treatment approaches for people with schizophrenia and comorbid substance use disorder(s) (SUD). The results show that despite the high prevalence of comorbid SUD among people with schizophrenia, there is a considerable shortage of rigorously conducted randomized controlled treatment trials. Although there is some evidence for clozapine, and for the adjunctive use of agents such as naltrexone for comorbid alcohol dependence, the available literature largely comprises case studies, case series, open label studies and retrospective surveys. In terms of psychosocial approaches, there is reasonable consensus that integrated approaches are most appropriate. Regarding specific aspects of care, motivational interviewing, cognitive behavioral therapy, contingency management, and family interventions have an emerging supportive literature. The authors state there is no ‘one size fits all’, and a flexible approach with the ability to apply specific components of care to particular individuals, is required. Group-based therapies and longer-term residential services have an important role for some patients, but further research is required to delineate more clearly which patients will benefit from these strategies. The authors conclude that although there is growing evidence that integrated and well articulated interventions that encompass pharmacological and psychosocial parameters can be beneficial for people with schizophrenia and comorbid SUD, there remains a considerable gap in the literature available to inform evidence-based practice

Psychotherapy for schizophrenia in an ACT team context
This case study discusses the treatment of a man diagnosed with schizophrenia with severe social anxiety. CBT approaches were used and treatment was conducted by a psychotherapist within the context of ACT services. CBT and ACT were found to be complementary, and the combination of approaches was found to be effective helping to reduce the client’s social anxiety. However, the client decided after all that he did not want to continue therapy. The authors recommend that clinicians working within ACT teams attempt to incorporate CBT approaches to better address the needs of their clients.

The inextricable nature of mental and physical health: Implications for integrative care.
This article provides evidence that physical health problems are caused and exasperated by psychological factors and psychological distress leads to physical disease. It argues that new approaches are needed to assure adequate professional knowledge of behavioral health at basic licensure, to increase the use of advanced practice psychiatric–mental health nurses in primary care set¬tings, to identify and teach behavioral competencies for primary care providers, and to fund the design and evaluation of integrative models of care.

Cognitive behavioural therapy for major psychiatric disorder: does it really work? A meta-analytical review of well-controlled trials.
This meta-analytical review of the CBT for major psychiatric disorders states that although cognitive behavioural therapy (CBT) is claimed to be effective in schizophrenia, major depression and bipolar disorder, there have been negative findings in well-conducted studies and meta-analyses have not fully considered the potential influence of blindness or the use of control interventions. In the current meta-analysis it found that CBT is no better than non-specific control interventions in the treatment of schizophrenia and does not reduce relapse rates.

Assertive community treatment of severe mental illness: a Canadian experience.
The study assessed one-year outcomes for 110 clients with serious mental illness who were randomly assigned to an assertive community rehabilitation program that provides psychiatric rehabilitation services in community settings or to hospital-based rehabilitation programs. Key elements of the community program include a multidisciplinary team on call 24 hours a day, in vivo treatment, and instruction and assistance in basic living skills. Data from client interviews after one year of service were used to assess clients' quality of life, satisfaction with services, and psychopathology. Clients in the assertive community rehabilitation program were more likely to be maintained in community settings and reported better quality of life than clients in the hospital-based programs.
