[Effect of changes in physical capacities upon personal social network in aging people].

The aim of the research is to assess whether there is change in the size and composition of older adults' personal network. Furthermore, change in contact frequency and received instrumental support within the relationships is studied. Five relationship types are distinguished: children, other kin, friends, neighbors and acquaintances. Older adults with a decline in physical capacity are compared with those with stable and increased capacities. Furthermore, differences according to (change in) partner status and age are investigated. Data are from the Longitudinal Aging Study Amsterdam, including the first and fourth observation of 1634 older adults living independently. The observation interval is 7 years. A decline in physical capacities is observed for 35% of the older adults, the capacities are stable for 60% and an increase is observed for 5% of the respondents. In general, network size and composition did not change. The frequency of contact within the relationships decreased. Decline was considerable for parent-child relationships, but relatively modest among older adults who faced a moderate to strong physical decline. However, among older adults who did not have a partner at the fourth observation and among the oldest (> 75 years) the frequency of contact with children increased, independently of the degree of physical decline. The decline in contact with neighbours was nearly absent for older adults who faced a moderate to strong physical decline; the contact increased when there was no partner at the fourth observation. The instrumental support received increased within all relationship types, independently of the degree of physical decline. It is concluded that research into determinants of the decline and increase in parent-child contacts is needed and that the meaning of neighbours should receive attention.
