Loneliness in (inter)action: Behavioral correlates of loneliness in friendship interactions

Previous studies have found that loneliness of one person can be judged quite accurately by a close friend or partner. Yet, it is unclear whether there are specific behavioral cues the other-ratings are based on. In the present study, 54 female friendship dyads were videotaped during a guided conversation and behavioral cuesl were coded using the SPAFF coding system. The results indicated that loneliness was negatively associated with one's own and the friend's overall friendship satisfaction and their satisfaction with the interaction. However, with the exception of an inconsistent mediation effect found for sadness, none of the coded behavioral cues were found to mediate the association between loneliness and interaction quality. Nevertheless, the results of the present study may help to understand why it is so difficult to identify people at risk for experiencing loneliness and draws attention to other processes through which loneliness may become visible to others.
