Developmental considerations in measuring children's disordered eating attitudes and behaviors.

This study examined the discriminant ability of the Children's version of the Eating Attitudes Test (ChEAT) clinical cut-off in a low/low-middle socioeconomic status, non-clinical sample of primarily Hispanic and non-Hispanic white (Caucasian) girls aged 8 to 12. We investigated how age, age-standardized body mass index (z-BMI), body dissatisfaction, body esteem, self-esteem, and depressive symptoms contributed to disordered eating status in 152 girls. Girls scoring at/above the ChEAT clinical cut-off reported significantly greater body dissatisfaction and depressive symptoms and lower body esteem than did girls who scored below the cut-off. We then investigated whether age moderated the discriminant ability of the ChEAT threshold and found that the ChEAT was significantly more sensitive when our sample was limited to 10- to 12-year-olds. An abbreviated 6-item ChEAT scale, based on marker items distinguishing at-risk and non-clinical status, was subsequently developed. Findings indicate that this abbreviated ChEAT scale has improved sensitivity with older girls (10- to 12-year-olds). However, sensitivity was unacceptable for younger girls (8- and 9-year-olds) for both the ChEAT and abbreviated ChEAT scale, regardless of cut-off.
