“…This supports Cantor's (1975) hierarchical model, which suggests that care is usually provided by the closest and most available person, with friends and family being used as last resort. Similarly, Johnson's (1983) shared-functioning model believed that no one family member was responsible for care, rather the entire family shares the responsibility, and Shanas' (1979) model of kin substitution also falls under the kin independence category, as Shanas believed kin substituted for kin. Thus, the phenomenon of kin independence clearly needs clari®cation as to whether the informal caregiver is receiving additional informal support from family members and friends or is the sole provider of care.…”
