Bivariate correlations between sensing metrics (GPS mobility and ambient audio) and loneliness, social functioning, and EMA reports of social engagement – Schizophrenia

GPS Mobility Number of Interactions (EMA) Proportion of Time Alone (EMA) UCLA-LS QLS-IR
Distance traveled (km) 0.065 −0.140 0.323 0.356
Mean flight duration (min) 0.154 0.173 0.466+ −0.404
Time at home (hrs) −0.372 0.289 −0.285 −0.088
Significant Locations (number) 0.064 −0.563* −0.583*+ −0.097
Pause (probability) −0.360 0.219 −0.174 0.070
Weekday routine −0.201 0.077+ −0.399 −0.136
Ambient Audio
rVAD 0.017 0.509* −0.446 0.394

Note. QLS-IR = Quality of Life Scale-Interpersonal relations; rVAD = robust Voice Activity Detection; UCLA-LS = UCLA Loneliness Scale; for UCLA-LS and QLS-IR, ns = 12 to 13 Light green = moderate effect; dark green = large effect;
