Comparing stress markers across various cohorts in a mobile setting

There exist multiple markers for measuring psychological stress, with varying specificities and sensitivities. However, in a real-life setting, there is limited data on how robust these methods may be especially in a relatively mobile context where the signal fidelity maybe limited. Thus any large scale data to inform how these methods perform, using commonly available sensors, based on both context and cohort characterization, can greatly add to our knowledge of their respective utility in real-life settings. This paper presents a study of 253 subjects which provides crucial data for analysing various stress markers in a mobile setting. We also provide early analysis results.
