Summary: | Objective
To evaluate the psychometric properties, including the factorial and predictive validity, of the Diet Readiness Test (DRT) in a clinical population.
Method
The DRT was administered to 132 women who participated in an obesity and binge eating treatment study.
Results
The DRT demonstrated adequate internal consistency. The DRT's proposed factor structure was not supported. Neither the DRT subscales nor the derived factors predicted changes in weight, binge eating, or exercise.
Discussion
The DRT did not demonstrate factorial or predictive validity in this study. Based on the DRT's cutoff criteria, 100% of the sample was considered not ready to begin a weight loss program, suggesting that the DRT may have limited utility with clinical populations. © 1998 by John Wiley & Sons, Inc.
