Loneliness trajectories

Abstract

This special section brings together five studies using group-based modeling to capture developmental trajectories of loneliness from age 7 through age 20. Together, the findings from these studies provide further evidence that developmental trajectories of loneliness are likely not best understood at a continuum but reflect distinct subpopulations that differ both where they start out and how they change over time in terms of mean levels of loneliness. Furthermore, adolescents who show chronically high loneliness or increasing loneliness over time exhibit poorer psychological and physical health, including greater incidence of depressive symptoms and more frequent suicide attempts. The findings from these studies also suggest that individuals experiencing increases in loneliness with age fare worse as well in terms of both physical and psychological health.
