The role of social network diversity in self-perceptions of aging in later life.

While the link between self-perceptions of aging (SPA) and healthy aging is well established, less is known about the association between social factors and SPA. The present study investigated whether higher social network diversity is associated with more positive and less negative SPA and whether this association is moderated by age. We examined cross-sectional data from the German Ageing Survey of 2008 (DEAS; N = 6205, 40-85 years, 49.5% female). Network diversity was assessed as the number of social roles in an individual's network (such as spouse, friend and colleague). Three domains of SPA were measured using the Aging-Related Cognitions Scale (AgeCog): ongoing development (positive SPA), social losses (negative SPA) and physical losses (negative SPA). We conducted multiple linear regression models and tested for a moderator effect of age using an interaction term of age and network diversity. Results showed that at higher ages older adults with higher network diversity reported more positive SPA related to ongoing development and more negative SPA related to social losses than those with less diverse networks, indicating that age has a moderating effect. We found no association between network diversity and negative SPA related to physical losses and no indication that age was relevant to this relationship. The present study adds to evidence on the role of social networks in SPA. Our findings suggest that in certain SPA domains and depending on age, network diversity is related to both more positive and more negative SPA, which emphasizes the importance of considering domain-specific SPA.
