Heather Juby of the Canadian RDC Network and I have started a blog on the topic of Clinical Depression in Canada .


When Does an Episode of Depression Require Treatment?

Depression occurs along a broad spectrum of severity, the extent to which treatment is needed for depression varies also. Almost all of the literature concerned with this decision emphasizes the severity of symptoms - ie. more severe depression is more likely to require treatment. However, the duration of symptoms may also be important.

Depressive Disorders in Dspace

The epidemiology of major depression is complex, and it is not an easy matter to anticipate the significance of traditional epidemiological estimates for health care practice and policy. To address this it may be helpful to maintain and update simulation models that can integrate epidemiological data from the best available sources, and provide an accessible visual summary of the epidemiology.

red dot We have used Markov models for this purpose.

red dot Discrete event simulation models may ulimately be more useful. An example can be found here.

Interventions for Stigma

Another area of interest for me is stigma. I am working on an agent-based model to help in understanding the population impact of anti-stigma interventions. The model is available here.
