 This scoping review of reviews examined existing literature on measures of emotional well-being, EWB. The review found that there was no consistent definition of EWB, measures varied widely and reviews were published in a range of disciplines. Additionally, the psychometric evidence varied and authors' purposes for conducting the reviews also differed. Overall, this suggests that literature on EWB measurement is disjointed and diffuse. Conceptual integration and harmonization of measures are necessary to advance knowledge of EWB and its measurement. This article was authored by Jessica B. Kosluski, Christine D.
