Interesting article on the use of self help books in the treatment of depression. I can definitely understand how these books may be beneficial, as it may provide help mechanisms. From my experience, help mechanisms can only do so much though, so it does depend on the cause of the depression as to whether this works on the individual or not. And of course on how much the individual is willing to help themselves and actively put into practise what the books may say. As mentioned in the article, books alongside other treatments for depression, in my opinion, would be the most beneficial.
