As exchanges of instrumental support between kin and non-kin remain essential to buffer the impact of critical life events, we consider the characteristics of personal configurations that may enhance or hinder them. Personal configurations vary in terms of their composition and two aspects of their structure: density and centrality. These dimensions are investigated to uncover whether they influence the type of instrumental support being exchanged (financial, material, and care) and the likelihood of their being reciprocal. Drawing on a representative sample of individuals living in Switzerland, results show that overall instrumental support is present in all personal configurations irrespective of their composition, but financial support is more prevalent in configurations based on parent–adult child relationships. Furthermore, configuration structures characterized by density of emotional support are positively associated with giving care support and with reciprocity, while those characterized by density of conflict are associated with giving less instrumental support overall.

Research on informal care-giving has largely neglected the contributions of non-kin carers. This paper investigated the characteristics and contributions of non-kin who care for older adults with a long-term health problem, and investigated friends and neighbours as distinct categories of care providers. Using data from 324 non-kin carers in the 1996 General Social Survey of Canada, this study compared individual and relationship characteristics, care tasks and amount of care provided for the two groups. Interpersonal and socio-demographic characteristics were investigated as mediators of potential differences between friends and neighbours in patterns of care. Results demonstrate that friend and neighbour carers differed on age, marital status, geographical proximity and relationship closeness. Friends were more likely than neighbours to assist with personal care, bills and banking, and transportation. Neighbours were more likely to assist with home maintenance. Friends provided assistance with a greater number of tasks and provided more hours of care per week, suggesting a more prominent role in the care of non-kin than neighbours. Age, income, a minor child in the household, proximity and relationship closeness significantly predicted amount of care provided, and relationship closeness largely explained differences between friends and neighbours. Future research on informal care-giving can build on the findings that distinguish friend and neighbour carers to further discriminate the dynamics of non-kin care.

Most published research on informal care for older people focuses on the support provided by relatives. The role of non-kin carers can, however, also be significant in supporting older people in their own homes. In this paper, we report the findings from an exploratory study of the support provided by friends and neighbours who are the main carers of frail older people. It draws on interviews with an opportunistic sample of friends, neighbours and older people, which explored their views about the support arrangements, the reasons why help was provided and any difficulties experienced. Several friends and neighbours provided intensive and frequent help, and some played a key role in co-ordinating other services. One of the main forms of direct support related to older people's quality of life, at a broader level than the practical help provided by statutory services. The flexibility of such support, and the friends' and neighbours' concern for older people as individuals, were particularly important to the people they helped. Nevertheless, such help was not provided without costs to the carers. The study highlights the need for policy-makers and practitioners not to take help from friends and neighbours for granted and, in line with the White Paper Modernising Social Services, to provide the support services they need.
