Combination of ESM with actigraphy in mobile device will allow us to map the type and level of activity of the youths in the flow of daily life. Actigraphy is an objective method of assessing sleep and circadian rhythm, as well as physical activity, using an electronic device, actigraph. It is a non-invasive tool that consecutively measures sleep quality and quantity across several days. Experience Sampling Methodology (ESM), available in smartphone app, is a structured diary in daily living environment^3,4,5, which captures subjective experiences in the moment without relying on recall.
