Mapping vulnerability factors of chronic emotional and social loneliness: A network analysis

Chronic loneliness adversely impacts both mental and physical health. As current interventions are only moderately effective, examining vulnerability factors reflected in interpersonal behavior and their relationships with specific chronic loneliness subtypes may provide insights. The present study explored the associations between loneliness vulnerability factors and two subtypes of chronic loneliness: chronic emotional loneliness (a longing for intimate connections) and chronic social loneliness (dissatisfaction with the quantity and quality of one's social network).

The sample consisted of 294 university students who had recently started at a new university. Participants completed surveys across three time points, separated by three-month intervals, including questionnaires on emotional and social loneliness, adult attachment styles, interpersonal behavioral styles, and features of emotional disorders. To explore relationships, we used network analysis by estimating a Mixed Graphical Model (MGM), in which chronic emotional loneliness and chronic social loneliness were dichotomized as binary variables (absence versus presence), while vulnerability factors were treated as continuous variables.

The network analysis demonstrated that chronic loneliness subtypes were differentially linked to vulnerability factors. Chronic emotional loneliness was predominantly linked to features of emotional disorders, whereas chronic social loneliness demonstrated a negative conditional association with secure attachment style.

The assessment of chronic loneliness was based on three time points, which does not capture potential fluctuations between assessments.

These findings highlight the importance of differentiating between chronic loneliness subtypes when examining vulnerability factors. By distinguishing these subtypes, tailored interventions for loneliness can be developed to enhance prevention.
