Objective. To assess the repeatability of the validated Flinders Calcium Food Frequency Questionnaire (FFQCA)
for estimating dietary calcium intake in a sample of community dwelling older Australians. Methods. A test-retest repeatability study involving 100 subjects (≥65
years) living independently in metropolitan Adelaide, Australia. Estimates of daily calcium intake from the first (FFQCA1)
and repeated administration (FFQCA2)
were calculated from two versions (35-item and 15-item) of the FFQCA. The intraclass correlation coefficient (ICC) was used to assess the repeatability. Results. Moderate and comparable ICC values (r = 0.5, r = 0.6) were found across the two versions of the FFQCA. Conclusion. Both FFQCA versions demonstrated moderate repeatability, supporting the results of previous studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
