The predictive validity of the Diet Readiness Test in a clinical population

Article Abstract:

Researchers investigated the validity of Brownell's Diet Readiness Test (DRT) for predicting factors including weight reduction and exercise participation. They tested the DRT on a group of 132 women who attended a 6-month treatment study on binge eating and weight loss. Results indicated that the DRT may have limited value for use with clinical participants. The DRT did not adequately predict changes in binge eating, weight or exercise. Possible reasons for the DRT's lack of validity could include the population type or the small amount of weight loss achieved.

Binge eating severity, self-concept, dieting self-efficacy and social support during treatment of binge eating disorder

Article Abstract:

There is evidence that binge eating, as with other eating disorders, is closely associated with low self-esteem and with feelings of failing to control eating. In the long term, improved social support may play a role in clinical improvement. In theory, it could be possible to limit binge eating through the use of aversive techniques, without having an impact on perceived self-control or improving self-image. This research did not produce conclusive results about the possible temporal links between treatment outcome and psychological factors.

The predictive validity of the diet readiness test in a clinical population

Article Abstract:

The Diet Readiness Test (DRT) has been developed to measure the readiness of an individual to begin a weight loss program, but little is known about its psychometric properties. A new study evaluates the psychometric properties of DRT, in terms of weight loss, exercise behaviour and binge eating, in a clinical population of 132 women who took part in an obesity and binge eating treatment study. It is shown that the DRT is unable to demonstrate predictive or factorial validity and suggests that it may have limited use in clinical populations.
