The purpose of this paper is to report research findings from a study of the nature of the relationship between informal and formal care of the elderly. There are several explanations for the link between informal and formal care: the task specific model, the compensatory model, the substitution model, the supplementary model, and the complementary model (which combines both the compensatory and supplementary functions of formal care). These explanations were evaluated using data from the 1985 General Social Survey for those aged 65 and older who have functional disabilities. Data were analysed using logistic regression analysis. The findings show support for the complementary function of formal care. The data indicate that formal care compensates for the absence of a spouse or child and, in a minority of cases, supplements work of the spouse or child caregiver for personal care tasks and to a lesser extent housework. Of these two, the compensatory effect of formal care appears to be more prevalent than the supplemental effect.
