https://researchdata.se/en/catalogue Search results en This dataset is connected to a study investigating how blue light exposure affects emotions, psychic health, and behaviours. The data material in this publication is a simulation of a forthcoming dataset. The forthcoming dataset will consist of three different data sources: self-reports and aggregated behavioral data from a survey, electrocardiograms, and behavioral data from an N-back task. A detailed description of the data collection and dataset can be found in the attached file "Data_collection_protocol.pdf". The codebook for the self-report measures consists of 286 rows, of which 14 are question texts and therefore not variables. The total number of variables is thus 272, which is the same as in the simulated dataset.
