The objective of this multidisciplinary, longitudinal study was to determine the reliability and concurrent and predictive validity of the DETERMINE Checklist. A combination of anthropometric and blood biochemistry values for a sample of older women, 61-82 years of age, were used as standards to determine validity. The checklist scores, which averaged 5.1 to 5.5, were significantly correlated across time providing evidence for reliability. The checklist identified 40% of the sample to be at high nutritional risk. However, anthropometric and biochemical data did not support this classification. For this apparently healthy group, the checklist was reliable, but the predictive validity was negligible.
