Summary
Obese individuals showed improved self-efficacy after a 26-week VLCD program. The Weight Efficacy Life-Style Questionnaire (WEL) scores significantly increased, demonstrating treatment effectiveness.
Area of Science:
- Obesity Research
- Behavioral Psychology
Background:
- Self-efficacy is crucial for obesity treatment success.
- Limited research exists on self-efficacy changes post-obesity interventions.
Purpose of the Study:
- To examine changes in self-efficacy among obese subjects after a multidisciplinary VLCD program.
- To assess the construct validity of the Weight Efficacy Life-Style Questionnaire (WEL).
Main Methods:
- Quasi-experimental study design.
- 26 obese subjects participated in a 26-week Very Low-Calorie Diet (VLCD) program.
- Pre- and post-treatment assessments using the WEL.
Main Results:
- Significant improvement in total WEL scores from pre- to post-treatment.
- Significant improvements across all five WEL situational factors: Negative Emotions, Availability, Social Pressure, Physical Discomfort, and Positive Activities.
- Demonstrated construct validity of the WEL.
Conclusions:
- Multidisciplinary VLCD programs can enhance self-efficacy in obese individuals.
- The WEL is a valid tool for measuring changes in self-efficacy related to obesity treatment.
- Provides benchmarks for expected WEL score changes in obesity treatment contexts.
