A Brief Note On Anorexia Nervosa And Bulimia Group

The researchers established validity and reliability for the numerous subscales, questions, and items throughout the assessment by obtaining many subsamples of individuals with anorexia nervosa and bulimia and a control group of individuals that did not have the disorder and looking at the results between the two. The researchers took three subsamples of female patients with anorexia nervosa that were being treated at the time. The patients were all at different steps in their treatment plans but none of the individuals were fully recovered. The control group was made up of three subsamples of females that were attending a university that were in a freshman or sophomore level psychology course and completing the questionnaire was optional. The researchers felt that in order for a specific subscale to be kept within the assessment and declared valid they would have to meet a few standards and be cross validated across various groups. The first standard that the items need to meet is for the subscale scores to be significantly different between the female control group and the anorexia nervosa and bulimia group. The second standard that the subscales had to meet is that the specific assessment item had to have more of a significant connection to the corresponding subscale than any other subscale in the assessment. The third standard that the subscales had to meet was that the â€Å"subscales had to have reliability coefficients above 0.80† in order for the anorexiaShow MoreRelatedEating Disorders : Anorexia Nervosa1477 Words   |  6 Pagesdisorders: anorexia nervosa, bulimia nervosa, and binge-eating disorder.
