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

GPS Mobility Number of Interactions (EMA) Proportion of Time Alone (EMA) UCLA-LS QLS-IR
Distance traveled (km) 0.603* −0.375 0.007 0.355
Mean flight duration (min) −0.466 −0.213 −0.581*+ −0.425
Time at home (hrs) −0.125 0.569* −0.309 −0.373
Significant locations (number) −0.158 −0.476 0.566+ 0.220
Pause (probability) 0.307 0.242 0.153 0.157
Weekday routine −0.167 0.699*+ −0.459 −0.412
Ambient Audio
rVAD 0.463 0.214 −0.280 0.142

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 orange = moderate effect; dark orange = large effect;
