Bulimia: prevalence and component factors in college women

Using a measure of bulimia (BULIT) that has demonstrated validity and reliability, the prevalence of bulimia among three samples of college females was found to range from 2.0 to 3.8%. These percentages are substantially lower than most previous reports would suggest. Factor analysis of the BULIT data revealed that the binging factor accounted for 63% of the variance. Other factors identified include vomiting, negative feelings about overeating, menstruation problems, preference for high caloric/easily ingested food, and weight fluctuations. The intercorrelations among the factors were examined and the implications of these data for the proposed revised DSM-III criteria for bulimia are discussed.
