Challenges in measuring and valuing productivity costs, and their relevance in mood disorders

Lost productivity is often excluded from economic evaluations, which may lead to an underestimation of the societal benefits of treatment. However, there are multiple-challenges in reliably estimating and reporting productivity losses. This article explores the main challenges, ie, selecting an appropriate valuation method (ie, human capital, friction cost, or multiplier), avoiding double counting, and accounting for equity. It also discusses the use of presenteeism instruments and their application in clinical trials, with a specific focus on their relevance in individuals with mood disorders. Further research and discussion is required on the development of reliable techniques for measuring and valuing productivity changes due to presenteeism.
