behaviors and restrained food intake


22/25

Descriptive statistics showed that the EB Checklistmeasured the factors that it purports to evaluateConfirmatory Factor Analysis supports the construct validity of the two instruments.low internal consistencies of the subscales were foundin the EB Checklist, as influenced by the small number

of items for each subscale

Research Implicationshow far most young womens self -esteem is attachedto their body weight, shape and size and what dietingor weight loss techniques they employ that may adversely affect their healthhow adolescent women cope with the pressure of media or society in achieving the ideal figure

how disordered eating patterns may lead these young women to other self-destructive behaviors likedrinking, smoking or self-injury
