According to the World Health Organization in 2012, depression is the leading cause of disability worldwide and represents a global public health challenge. Due to its early adult onset, its effect on lifestyle behaviors may contribute to the onset or worsening of medical illnesses. It is also estimated that depression costs employers $44 billion per year in lost productivity, more than three times greater than the estimated $13 billion attributed to those with non-depressive illnesses (Kessler, et al., June 2003).

The evidence is compelling that individuals with depression are less well off than individuals without depression, in terms of overall health and functioning. Additionally, the cost to society in health care expenditures as well as productivity requires structured programming aimed at identification, education and intervention to reduce the incidence of depression and the associated conditions.
