What this means
Researchers looked at who felt less lonely after using a social robot. People who had less social contact before the program saw bigger drops in loneliness. Future trials should check whether past social contact changes how well these robots work.

Abstract
Among community-dwelling older adults living alone, less frequent preintervention social contact was associated with greater reductions in loneliness during a social robot intervention. Future trials should examine whether preintervention social contact modifies the effects of social robot interventions.
