ABSTRACT
Participants in the Multiple Risk Factor Intervention Trial (MRFIT) were taught not only how to modify the fat content of their diets but also how to assess their success in doing so. To simplify the process, a food scoring system was developed in which positive points are assigned to high-saturated-fat and high-cholesterol foods and negative points to foods and high-polyunsaturated-fat and low-cholesterol content. Using special forms supplied by MRFIT nutrition counselors, participants were able to self-monitor their dietary regimens. The method is described and forms are illustrated.

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
