Query: Measuring Adolescents' Well-being: Correspondence of Naive Digital
  Traces to Survey Data   Digital traces are often used as a substitute for survey data. However, it is
unclear whether and how digital traces actually correspond to the survey-based
traits they purport to measure. This paper examines correlations between
self-reports and digital trace proxies of depression, anxiety, mood, social
integration and sleep among high school students. The study is based on a small
but rich multilayer data set (N = 144). The data set contains mood and sleep
measures, assessed daily over a 4-month period, along with survey measures at
two points in time and information about online activity from VK, the most
popular social networking site in Russia. Our analysis indicates that 1) the
sentiments expressed in social media posts are correlated with depression;
namely, adolescents with more severe symptoms of depression write more negative
posts, 2) late-night posting indicates less sleep and poorer sleep quality, and
3) students who were nominated less often as somebody's friend in the survey
have fewer friends on VK and their posts receive fewer "likes." However, these
correlations are generally weak. These results demonstrate that digital traces
can serve as useful supplements to, rather than substitutes for, survey data in
studies on adolescents' well-being. These estimates of correlations between
survey and digital trace data could provide useful guidelines for future
research on the topic.
