Hypothesis
How do exercise and weight management psychosocial variables predict weight change in a short-term intervention?
Conclusion
The study found that changes in weight management self-efficacy were the strongest predictors of short-term weight loss.
Supporting Evidence
- Weight management self-efficacy was the strongest predictor of weight loss.
- 20-30% of variance in weight change was explained by the models.
- Exercise-related variables showed moderate associations with weight loss.
Takeaway
This study shows that believing in yourself can help you lose weight, especially when you change how you think about eating and exercise.
Methodology
142 overweight and obese women participated in a 16-week weight control program, with assessments of body weight and psychosocial variables at baseline and program's end.
Potential Biases
Self-reported data may lead to inaccuracies in the reported psychosocial variables.
Limitations
The study lacked a control group and relied on self-reported data, which may introduce bias.
Participant Demographics
Participants were overweight and obese women with a mean age of 38.3 years.
