Epidemiological studies of depression give important insights into populations at higher risk of depression, but not everyone in certain high-risk circumstances will develop a clinical depression. ‘Models of depression’ highlights some of the most well-known biological, psychological, and social models ranging from the monoamine hypothesis to Beck’s cognitive model, and then discusses attempts to integrate these into a multi-dimensional psycho-bio-social theory. It highlights the interaction between stress and vulnerability factors, and the importance of considering the origins of the vulnerabilities. In reality, there is no one cause and no single pathway to depression and multiple factors increase vulnerability to depression.
