European and Canadian studies of loneliness among seniors.

This article provides a commentary on a set of five other articles reporting European and Canadian studies of loneliness among seniors. It places those works involving Canadian, Dutch, Finnish, and Welsh samples in the larger context of research on loneliness; offers reflections on the methods and findings reported in the articles; and addresses the question, Is loneliness universal? Points of similarity in the articles are identified and possible ways of reconciling discrepant findings regarding age trends and gender differences are put forward. A discrepancy model of loneliness is used as a key framework for explaining several points, including why objective social isolation and loneliness don't always go together.
