Wider, faster, more: Re-envisioning the treatment and research of depression to address its public health burden in the United States
Depression and other internalizing disorder symptoms are leading causes of disability in theUnited States. Although there are effective interventions, the burden of disability attributableto internalizing disorder symptoms is not decreasing. I review clinical and epidemiological datato identify solutions to the public health burden of internalizing disorder symptoms. Contemporary research efforts have a focus on treatment development and the identification of biomarkers of response. However, these solutions are not scalable because internalizing disorders are much more common than usually appreciated and there are substantial disparities in access to mental health care. Improving the dissemination of individual interventions may also be of limited value given data suggesting that high rates of symptom remission can only be achieved with multiple (e.g., 4-10) treatment steps. The logic of stepped care approaches for internalizing disorders is well-supported by these data, but initial treatments likely should be low-intensity and “stepping up” should occur more quickly than usually done in most trials. Efforts that promise to make an impact in the public health burden of internalizing disorder symptoms need to consider their high prevalence and heterogeneity in the level of care as well as in the mechanisms that treatments may need to engage.
