Query: Improving Prediction of Real-Time Loneliness and Companionship Type
  Using Geosocial Features of Personal Smartphone Data   Loneliness is a widely affecting mental health symptom and can be mediated by
and co-vary with patterns of social exposure. Using momentary survey and
smartphone sensing data collected from 129 Android-using college student
participants over three weeks, we (1) investigate and uncover the relations
between momentary loneliness experience and companionship type and (2) propose
and validate novel geosocial features of smartphone-based Bluetooth and GPS
data for predicting loneliness and companionship type in real time. We base our
features on intuitions characterizing the quantity and spatiotemporal
predictability of an individual's Bluetooth encounters and GPS location
clusters to capture personal significance of social exposure scenarios
conditional on their temporal distribution and geographic patterns. We examine
our features' statistical correlation with momentary loneliness through
regression analyses and evaluate their predictive power using a sliding window
prediction procedure. Our features achieved significant performance improvement
compared to baseline for predicting both momentary loneliness and companionship
type, with the effect stronger for the loneliness prediction task. As such we
recommend incorporation and further evaluation of our geosocial features
proposed in this study in future mental health sensing and context-aware
computing applications.
