如果参与者坚持减少卡路里的饮食处方，并可能受到外部或内部因素(如压力)引发的饮食失误的破坏，减肥干预就是成功的。这项研究的目的是检验基于接受的治疗(ABT)与标准行为治疗(SBT)是否缓和了压力对饮食失误的影响。生态瞬时评估数据来自189名参与者，他们被随机分配到ABT或SBT。受试者之间和受试者内部的压力被用来预测失误的发生和干预条件，干预条件和压力之间的交互作用采用广义线性混合效应模型。控制变量包括性别、一天中的时间和基线平均失误次数/天。较高的平均基线失误/天、女性性别和一天中较晚的时间与失误几率的增加显著相关。受试者之间的压力与失误的几率呈显著正相关。与SBT相比，ABT显示个体在受试者内部压力的平均水平上的失误几率显著降低，但干预条件与受试者内压力的交互作用在统计学上并不显著。总体压力水平较高的参与者比总体压力水平较低的参与者更容易出现失误。在参与者自己的平均压力水平上，ABT组的失误几率显著降低，这表明ABT在参与者通常的压力水平上可能是有益的，但当他们偏离他们通常的压力水平时，没有治疗上的差异。
Weight toss interventions are successful to the extent that participants adhere to calorie-reduced dietary prescriptions and may be undermined by dietary lapses triggered by external or internal factors, such as stress. The purpose of this study was to examine whether an acceptance-based treatment (ABT) versus a standard behavioral treatment (SBT) moderated the effect of stress on dietary lapses. Ecological momentary assessment data were collected from 189 participants who were randomly assigned to either ABT or SBT. Between-subject and within-subject stress were used to predict lapse occurrence along with intervention condition, and the interaction between intervention condition and stress using a generalized linear mixed-effects model. Gender, time of day, and baseline mean lapses/day were included as control variables. Higher mean baseline lapses/day, female gender, and later time of day were significantly associated with increased odds of lapse. Between-subject stress was positively and significantly related to the odds of lapse. Compared to SBT, ABT showed a significant decrease in the odds of lapse at an individual's average level of within-subject stress, but the interaction of intervention condition with within-subject stress was not statistically significant. Participants with high overall stress levels lapsed more frequently than those with low overall stress levels. There was a significant decrease in the odds of lapse for the ABT group at a participant's own average stress level, suggesting that ABT may be beneficial at participants' usual stress levels but when they deviate from their usual stress level, there are no treatment differences.
