A single summative global scale of disordered eating attitudes and behaviors: Findings from Project EAT, a 15-year longitudinal population-based study.

ABSTRACT:

Objective

The Project EAT Disordered Eating Attitudes and Behaviors (DEAB) scale was created from disordered eating attitudes and behaviors that tend to interrelate. To examine the appropriateness of the scale, we assessed the fit (i.e., how well a single latent factor fits a set of interrelated disordered eating attitudes and behaviors) and the convergent validity over time.

Method

Five interrelated disordered eating attitudes and behaviors were assessed in a longitudinal cohort (Project EAT, age 11 to 18 in 1998-1999, N = 1492). Confirmatory factor analysis examined the appropriateness of the DEAB scale. To examine whether individual variables function differently in relation to the latent construct across time, two models were compared: one requiring indicator-level facto
