We examined the relationships between promotion and prevention focus and caloric consumption in reaction to a dietary lapse scenario among weight loss maintainers. Participants were 65 adult females who had attained and maintained a weight loss of 10 % or more for at least 1 month. After engaging in a dietary lapse in a feeding laboratory, participants completed a "bogus" taste test, during which they could consume as much food as they liked. It was hypothesized that promotion and prevention focus would predict caloric consumption, mediated by depressive and anxious affect. Prevention focus, but not promotion focus, was positively associated with proportion of daily calories consumed. Affect was not a mediator. Prevention focus may be deleterious for dietary maintenance following dietary lapses. Theoretical and clinical implications are discussed in light of prior research. Limitations of the study and recommendations for future research also are presented.
我们研究了在减肥维持者面对饮食失误情景时，促进型和预防型焦点与热量摄入之间的关系。参与者为65名成年女性，她们已实现并维持体重减轻10%或更多至少1个月。在进食实验室经历饮食失误后，参与者完成了一项“假的”味觉测试，在此期间他们可以随意食用尽可能多的食物。研究假设促进型和预防型焦点将通过抑郁和焦虑情绪来预测热量摄入。预防型焦点而非促进型焦点与每日摄入热量的比例呈正相关。情绪并非中介因素。预防型焦点可能对饮食失误后的饮食维持有害。根据先前的研究讨论了理论和临床意义。还介绍了该研究的局限性以及对未来研究的建议。
