Does Diversity of Social Ties Really Matter More for Health and Leisure Activity than Number of Social Ties? Evidence from Later Adulthood.

Objectives: Claims that the diversity of social ties matters more for health than the sheer number of ties have largely gone untested. This study accordingly compared the unique associations of number versus diversity of social ties with key health-related outcomes: functional limitations and leisure activities. Additionally, positive and ambivalent ties were distinguished.

Methods: Social networks, health, and leisure activities were assessed in a national sample of older adults ( = 874; ages 65-91).

Results: Regression analyses revealed that number of ties related to each outcome at a magnitude comparable to, or exceeding, that of diversity in most models. For positive ties, number related more strongly than diversity to greater leisure activities. For ambivalent ties, number related more strongly than diversity to worse functional limitations.

Discussion: Contrary to prevailing views, diversity of ties is not necessarily more important than number of ties. Findings extend scientific understanding and approaches to interventions.
