The relationship between state and trait loneliness and social experiences in daily life
Loneliness, or the subjective experience of social disconnection, is often thought of as a stable characteristic. However, emerging data suggest that experiences of loneliness fluctuate within people over time. Understanding the momentary correlates of state experiences of loneliness can help identify and address the negative consequences of such experiences. Further, the relationship between trait (dispositional) and state (momentary) loneliness remains poorly understood. Identifying the extent to which trait loneliness might moderate momentary associations can inform understanding of their interactions and inform treatments at the within- and between-person levels. In the current ecological momentary assessment (EMA) study, 32 adult participants (mean age = 25) reported on momentary loneliness and qualities of social interactions four times per day for seven days using a smartphone application. Participants also reported on trait loneliness. We found that trait and state loneliness were correlated in the same directions with multiple daily social experiences. Importantly, momentary social appraisals (i.e., rejection/criticism from previous interaction(s), a preference to be alone when with others, feeling connected to others when alone, and hypervigilance to future social threat) were related to more state loneliness, while interacting with others and feeling happy in the moment were related to less state loneliness. These relationships were not moderated by trait loneliness, with one exception: People higher in trait loneliness exhibited a stronger relationship between a preference to be alone when with others and more state loneliness. These results suggest that social appraisals, particularly negative perceptions of social experiences, are important factors in influencing state loneliness, regardless of one’s general tendencies to feel lonely. On the other hand, those higher in trait loneliness are more likely to feel lonely in moments when they are with others but prefer to be alone.
