Approaches to Understanding and Addressing Treatment-Resistant Depression : A Scoping Review

Abstract EN

Treatment-resistant depression is associated with significant disability and, due to its high prevalence, results in substantive economic and societal burden at a population level.

The objective of this study is to synthesize extant literature on approaches currently being applied to understand and address this condition.

It is hoped that the findings can be used to inform practitioners and guide future research.

A scoping review of the scientific literature was conducted with findings categorized and charted by underlying research paradigm.

Currently, the vast majority of research stems from a biological paradigm (81%).

Research on treatment-resistant depression would benefit from a broadened field of study.

Given that multiple etiological mechanisms likely contribute to treatment-resistant depression and current efforts at prevention and treatment have substantial room for improvement, an expanded research agenda could more effectively address this significant public health issue.
