Abstract
This trial aimed to assess the effect of an acceptance and commitment therapy (ACT) and mindfulness-based intervention on the various psychological and physical issues associated with obesity. A parallel group randomized controlled trial was conducted with 142 adults with body mass indexes in the overweight or obesity range seeking treatment. Participants were assigned either to the ACT and mindfulness-based group intervention (Mind&Life intervention) plus treatment as usual (TAU) or the TAU-only condition. Individuals receiving the Mind&Life intervention with TAU showed more adherence to the Mediterranean diet, and greater decrease in external eating, weight, and visceral fat both at posttreatment and at 6-month follow-up. Moreover, they displayed a greater reduction in total protein and animal protein intake and GPT enzymes level. By 6-month follow-up, the Mind&Life group experienced a lower impact of weight on quality of life than TAU participants. However, Mind&Life intervention completers showed greater restrained eating levels at follow-up. Overall, this study suggests that an ACT and mindfulness-based group intervention could produce improvements in the impact of weight on quality of life, some eating behaviors, dietary habits, and weight and body composition parameters of people facing weight-related challenges.
期刊介绍：
The Journal of Contextual Behavioral Science is the official journal of the Association for Contextual Behavioral Science (ACBS).
Contextual Behavioral Science is a systematic and pragmatic approach to the understanding of behavior, the solution of human problems, and the promotion of human growth and development. Contextual Behavioral Science uses functional principles and theories to analyze and modify action embedded in its historical and situational context. The goal is to predict and influence behavior, with precision, scope, and depth, across all behavioral domains and all levels of analysis, so as to help create a behavioral science that is more adequate to the challenge of the human condition.
