Identified mediators for medium-/long-term weight control were higher levels of autonomous motivation , self-efficacy/barriers , self-regulation skills ( such as self-monitoring ) , flexible eating restraint , and positive body image .
For physical activity , significant putative mediators were high autonomous motivation , self-efficacy , and use of self-regulation skills .
For dietary intake , the evidence was much less clear , and no consistent mediators were identified .
Conclusions This is the first systematic review of mediational psychological mechanisms of successful outcomes in obesity-related lifestyle change interventions .
Despite limited evidence , higher autonomous motivation , self-efficacy , and self-regulation skills emerged as the best predictors of beneficial weight and physical activity outcomes ; for weight control , positive body image and flexible eating restraint may additionally improve outcomes .
These variables represent possible targets for future lifestyle interventions in overweight/obese population
Background Relapse is high in lifestyle obesity interventions involving behavior and weight change .
Identifying mediators of successful outcomes in these interventions is critical to improve effectiveness and to guide approaches to obesity treatment , including re source allocation .
This article review s the most consistent self-regulation mediators of medium- and long-term weight control , physical activity , and dietary intake in clinical and community behavior change interventions targeting overweight/obese adults .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
