An Evaluation of the Psychometric Properties of the Behavior Change Strategies for Healthy Eating Scale
AbstractBackground and Purpose:
The Behavior Change Strategies for Healthy Eating Scale (BCSHES) has potentially broad implications for use by researchers, practitioners, and educators across various medical and allied health professions. To date, however, the psychometric properties of the BCSHES have not been rigorously evaluated, potentially limiting its use. The purpose of this study was to thoroughly evaluate the psychometric properties of the BCSHES.Methods:
The Rasch Rating Scale Model was used to analyze BCSHES data on a sample of 191 graduate/professional program students.Results:
Messick's framework for construct validity was used to discern validity evidence, which noted the BCSHES possessed very strong psychometric properties and is capable of yielding valid and reliable scores.Conclusions:
Use of the scale is encouraged, where appropriate.
