title: Explanatory variance in bulimia nervosa.
abstract: In order to prevent disease, one must understand the factors that contribute to the variance of the illness. In an effort to better understand factors that contribute to bulimia nervosa (BN), a study was designed to investigate explanatory factors in BN. Of particular interest to the researchers in the study was the effect of the Hispanic subculture on the variance of BN. Female participants (n = 372) and male participants (n = 109) from the ages of 17-49 agreed to serve in the study. A self-report scale designed to assess the symptoms of BN was the criterion variable in the study. Predictor variables included in the regression model were drive for thinness, body mass index (BMI), age, and ethnicity (Hispanic or Anglo). Separate analyses were run for males and females. Based on the results of the analysis it seems that the desire to be thinner and an individual's BMI contribute to the variance in BN for females, but not for males. There was no difference in the attitudes associated with BN between Hispanic (n = 27) and Anglo (n = 321) females.
