Objectives: Epidemiologic studies have confirmed that major depression (MD) is an extremely common condition, but also one that is associated with an unexpectedly broad spectrum of morbidity. It is no longer a tenable position to regard MD as being a simple indicator of treatment need, nor is a one-size-fits-all approach to treatment likely to be an effective guide to health care delivery. The objective of this commentary is to explore the implications of these new epidemiologic findings for policy and practice in Canada.Method: This paper is a selective review and commentary.Results: Whereas the acute and long-term treatment needs of a subset of individuals with MD have received much attention in the literature, the needs of other groups have not. A sizable proportion of individuals with episodes meeting the Diagnostic and Statistical Manual of Mental Disorders-fourth edition definition in community populations may not need the intensive treatment emphasized by current Canadian practice guidelines. The strategy of watchful waiting may have a role in primary care. On the policy front, guided and perhaps self-guided management strategies deserve greater emphasis than they have received. Stepped-care strategies are an appealing option, but how best to effectively implement these in the Canadian context is unclear.Conclusions: The spectrum of morbidity among individuals with MD in community populations is much wider than has been previously appreciated. The health system should respond with an appropriate spectrum of services, but many questions remain about how to facilitate this. [ABSTRACT FROM AUTHOR]

It is time to move beyond education about qualitative research theory and methods to using them to understand and improve psychiatric practice. There is a good fit between this agenda and current thinking about research use that broadens definitions of evidence beyond the results of experiments. This paper describes a qualitative program evaluation to illustrate what kind of useful knowledge is generated and how it can be created through a clinician-researcher partnership. The linkage and exchange model of effective knowledge translation described involves interaction between clinicians and researchers throughout the research process and results in mutual learning through the planning, disseminating, and application of existing or new qualitative research in decision making.

Objective: Publicly funded cognitive-behavioural therapy (CBT) for mental disorders is scarce in Canada, despite proven efficacy and guidelines recommending its use. This paper reviews published data on the economic impact of CBT to inform recommendations for current Canadian mental health care funding policy.Method: We searched the literature for economic analyses of CBT in the treatment of mental disorders.Results: We identified 22 health economic studies involving CBT for mood, anxiety, psychotic, and somatoform disorders. Across health care settings and patient populations, CBT alone or in combination with pharmacotherapy represented acceptable value for health dollars spent, with CBT costs offset by reduced health care use.Conclusions: International evidence suggests CBT is cost-effective. Greater access to CBT would likely improve outcomes and result in cost savings. Future research is warranted to evaluate the economic impact of CBT in Canada. [ABSTRACT FROM AUTHOR]
