Assessing dietary adherence in the Multiple Risk Factor Intervention Trial (MRFIT). II. Food record rating as an indicator of compliance.
The reliability of the food record rating (FRR) sytem devised for assessing nutritional compliance by participants of MRFIT was statistically validated. Two nutritionists in each of four clinical MRFIT centers each rated thirty records drawn from a pool of 120 records from twenty centers. The eight raters working independently in four cities were able to duplicate FRR scores 86 per cent of the time. The FRR provides a systematic, rapid measure of progress in food-habit change which would be applicable to other preventive nutrition programs
