Loneliness and depressive symptoms: The mediating and moderating role of uncontrollable ruminative thoughts

Although feelings of loneliness often are accompanied by depressive symptoms, little is known about underlying mechanisms in this association. The present study sampled 370 college freshmen and investigated whether rumination (and its components of Uncontrollability, Causal Analysis, and Understanding) functioned as a mediator or moderator in the relationship between 2 types of loneliness (as experienced in the relationship with parents and with peers, respectively) and depressive symptoms. Results indicated that rumination partially mediated the relationship between peer-related loneliness and depressive symptoms and moderated the relationship between parent-related loneliness and depressive symptoms. In addition, the uncontrollable nature, rather than the content, of these ruminative thoughts about parent- and peer-related loneliness was particularly harmful in the development of depressive symptoms. Implications and suggestions for future research are discussed.status: publishe
