An ounce of prevention is worth a pound of cure is how the old saying goes, and when it comes to mental health, nothing could be more true. The cost of depression is high, both for the people struggling with the disease and for all of those in their work, family and social circles. Depression can rob a family of its parents or a child of his or her childhood. It steals cash from businesses in terms of lost productivity, and robs individuals of enjoyment of life. And yet the lion’s share of the depression-related research has focused on treatment, not prevention, of this disease. Understanding how to prevent depression, especially among those already considered to be at high risk for developing the disease, is an important and valuable contribution to the research literature.
