The Financial Impact Scale (FIS) was designed for use with all informal long-term caregivers. The FIS provides a mechanism by which this relatively ignored dimension of caregiving can be measured. Scale development results with 98 subjects yielded a unidimensional scale with a Cronbach's Alpha of .9324. Correlations of the FIS with the Zarit Burden Scale (1980) and the two Hafstrom and Dunsing (1973) measures of financial well-being proved the FIS to be a valid instrument that is a sensitive measure of differences in financial impact.
