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 .
A self-regulation lifestyle program for post-cardiac rehabilitation patients has long-term effects on exercise adherence
As maintenance of lifestyle change and risk factor modification following completion of cardiac rehabilitation has been shown to be notoriously difficult , we developed a brief self-regulation lifestyle program for post-cardiac rehabilitation patients . R and omized-controlled trial . Following completion of cardiac rehabilitation 210 patients were r and omized to receive either a lifestyle maintenance program ( n = 112 ) or st and ard care ( n = 98 ) . The program was based on self-regulation principles and consisted of a motivational interview , 7 group sessions and home assignments . Risk factors and health behaviors were assessed at baseline ( end of cardiac rehabilitation ) , and 6 and 15 months thereafter . ANCOVAs showed a significant effect of the lifestyle program on exercise behavior at 15-month follow-up . Mediation analysis demonstrated that the treatment effect on exercise behavior could be explained by self-regulation skills . Chi squared tests showed that patients in the intervention group had significantly fewer uncontrolled risk factors as compared to the control group . Finally , the lifestyle intervention program was associated with a 12 % reduction in self-reported cardiac hospital admission rates . This trial indicates that a relatively brief , theory-based lifestyle program is capable of inciting and maintaining improvements in exercise adherence . It is suggested that patients may need ongoing attention and guidance , for example in the form of ( internet-based ) booster sessions , as long-term consolidation of changes is arduous
