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 .
Changes in cognitive measures associated with a lifestyle program for treated hypertensives: a randomized controlled trial (ADAPT).
Cognitive changes are reported infrequently in programs targeting cardiovascular risk . We examined self-efficacy , behavioral barriers and health beliefs in a lifestyle program for drug-treated hypertensives that aim ed to reduce blood pressure , antihypertensive drug needs and cardiovascular risk . In a r and omized controlled trial , we compared usual care ( controls ) and a 4-month program focusing on weight loss , diet and exercise . Outcomes were assessed at baseline , 4 months and 1-year follow-up . Of 241 individuals r and omized , 102/123 in the program and 90/118 of controls completed follow-up . In the program group , dietary barriers fell by 14 % at 4 months ( controls 2 % , P = 0.025 ) and by 8 % at follow-up ( controls 3 % , P = 0.010 ) . Exercise barriers fell by 11 % at 4 months ( controls 3 % , P = 0.020 ) and 17 % ( controls 4 % , P = 0.002 ) at follow-up . Dietary self-efficacy improved by 3 % at 4 months ( controls -1 % , P = 0.003 ) and by 2 % at follow-up ( controls -1 % , P = 0.051 ) . Exercise self-efficacy increased by 8 % at 4 months ( controls 3 % , P < 0.001 ) and by 5 % at follow-up ( controls 3 % , P = 0.130 ) . Changes in cognitive variables predicted changes in health-related behaviors at 4 months and follow-up . A cognitively based lifestyle program in treated hypertensives is associated with improvements in cognitive measures in the shorter and longer term
