Caregiving networks-using a network approach to identify missed opportunities.

OBJECTIVES
This study demonstrates the added value to caregiving research by using a multi-informant social network approach within the context of Alzheimer's disease and related dementia.


METHOD
Sixty-six informants from 24 families enumerated caregiving network members in 2012. Comparisons were made between networks based on a single informant versus multiple informants in terms of network composition and caregiving roles, core-periphery structure, and identification of "missed opportunities" in recruitment.


RESULTS
On average, each informant beyond the index enumerated 6.2 new members, resulting in about 10 new members per family network when the multiple-informant approach is used. Compared with index informants' networks, multi-informant networks showed an 85% increase in identification of direct care providers (1.71 compared with 3.42) and a 48% increase in identification of those involved in care decision making (3.33 compared with 4.92). Informants from the same network generally showed agreement in reported participation in caregiving activities. However, the reports of non-participation in these roles were less consistent among the informants. Resulting structure indicated a core caregiving network (M = 6.12 members), with semi-peripheral and peripheral members (M = 5.19 and M = 14.83 members, respectively).


DISCUSSION
Results suggest that an iterative, targeted sampling approach with at least three informants allows for a more comprehensive assessment of caregiving processes. Applying this approach in future research will greatly enhance our knowledge and better inform future interventions to facilitate family adaptation.
