Development and preliminary validation of the cognitive behavioral dieting scale

Area of Science:

• Psychology
• Behavioral Science
• Health Psychology

Background:

• Dieting is a common behavior with significant implications for health and well-being.
• Existing measures may not fully capture the cognitive and behavioral aspects of current dieting practices.
• A validated scale is needed to accurately assess dieting behavior for research purposes.

Purpose of the Study:

• To empirically develop and validate the Cognitive Behavioral Dieting Scale (CBDS).
• To create a reliable and concise measure of current dieting behavior and associated thoughts.
• To assess the scale's ability to predict relevant outcomes and its construct validity.

Main Methods:

• Item generation and refinement to enhance internal consistency and reduce scale length.
• Factor analysis and reliability testing (internal consistency and test-retest).
• Evaluation of predictive validity for calorie intake and negative calorie balance, and construct validity against related psychological constructs.

Main Results:

• The final CBDS is a 14-item scale with high internal consistency (α = .95) and test-retest reliability (r = .95).
• The CBDS demonstrated predictive validity for calorie intake and negative calorie balance, independent of physical variables like BMI.
• Construct validity was supported, showing associations with body image esteem and dietary restraint, but minimal relation to healthy eating self-efficacy.

Conclusions:

• The CBDS is a promising, valid, and reliable measure for assessing current dieting behavior.
• This scale offers a distinct construct from dietary restraint and measures dieting on a continuum.
• The CBDS has potential utility in future research on eating disorders, dietary restraint, and obesity.
