The purpose of this Toolbox is to have a resource of stress measures within the stress domains listed below. Network members and their colleagues who have expertise in the domain were asked to choose several measures they value, and describe the different aspects of each measure. Instead of ‘recommending’ a measure, we asked researchers to instead describe the differences between each measure. In this way, researchers designing new studies can implement the measure that best captures the aspect of stress that aligns with their interest and hypotheses. Other resources have been created that take more comprehensive and empirical approaches to psychosocial measure recommendations such as those found here: ADOPT, NIH Toolbox, PROMIS, and PhenX Toolkit. This is a living document so we welcome any input and suggested edits!
